Be cautious when heading to Florida’s beaches this summer, an expert warned, as a 5,000-mile floating mass of sargassum seaweed has begun washing up on the state’s shores. It can be low risk in some instances, but it also has the potential for triggering serious respiratory health issues. “The sargassum itself is not dangerous. It can have different jellyfish and sea creatures in it that could be a source of sting,” said Dr. Sarah Shafer, medical toxicologist and an assistant professor in the department of emergency medicine at Baylor College of Medicine in Houston. However, “once the sargassum washes up on the beach, in 48 hours it will start to break down and lose toxic gasses. As it decomposes, we have to worry about potential exposure to humans.” Sargassum can decompose in one of several ways. It can release ammonia and hydrogen sulfide, which is toxic, she explained in a college news release. Even at low levels, hydrogen sulfide can produce the smell of rotten eggs. Yet when the gas reaches a certain level, humans can become “nose-blind” and not smell it. “At low levels, it smells like rotten eggs in the air. This happens in natural hot springs, like at Yellowstone. It can cause some irritant effects,” Shafer said. “In high levels, it can cause sudden death.” This can be a concern in closed-off…  read on >  read on >

Heavy users of marijuana might face an increased risk of bipolar disorder and depression, a new study suggests. The analysis of more than 6.6 million Danish individuals found that having cannabis use disorder doubled or even tripled the odds for most forms of depression or bipolar disorder. When it came to bipolar disorder in particular, “cannabis use disorder was associated with higher risk for psychotic than non-psychotic subtypes of bipolar disorder,” the researchers noted. These results, however, cannot prove that marijuana use was the cause of these conditions, the investigators said. “Our results are compatible with the idea that cannabis may increase the risk of developing depression or bipolar disorder, but we cannot prove this for certain, since we are working with observational data,” explained lead researcher Dr. Oskar Jefsen, from the psychosis research unit at Aarhus University in Denmark. “Unequivocal evidence would require a randomized controlled trial, but this would be unethical.” Still, one expert noted that while the study can’t prove that cannabis was the cause of bipolar disorder or depression, it adds to growing evidence that the drug is not harmless. “This is a powerful and well-conducted study that adds to the emerging evidence of the added risk of cannabis regular use to the development of serious mental health disorders,” said Beatriz Carlini, director of the Cannabis Research and Education program and…  read on >  read on >

Attachment theory sounds like a complicated concept, but when you’re a parent it can sometimes boil down to a crying, clinging child who does not want to be separated from you. Put simply, attachment theory explores the lasting psychological and emotional bonds between individuals. Developed by British psychologist John Bowlby and then expanded by scientist Mary Ainsworth, think of attachment theory as a lasting feeling of connectedness between human beings. Here, experts offer insights into its core principles, stages and attachment styles. Bowlby emphasized the significance of secure infant-caregiver attachments, proposing distinct stages in attachment formation. Ainsworth’s research introduced different attachment styles. Understanding attachment theory can help you navigate relationships and emotions with greater understanding and empathy. What is attachment theory? Attachment theory is explained in a video published by students from McMaster University, in Ontario, Canada. In the video, students explain that the theory of attachment was discovered by John Bowlby, a British psychologist, back in 1969. Bowlby was trying to comprehend the intense distress experienced by infants who had been separated from their parents. Bowlby believed that behaviors such as crying and searching were adaptive responses to separation from a primary attachment figure who provides support, protection and care. Bowlby attachment theory Bowlby’s theory of attachment, as outlined in a recent article published by Simply Psychology, highlights the importance of secure attachments between…  read on >  read on >

Ketamine may be an alternative to shock treatment for people with treatment-resistant major depression, a new study suggests. Currently, patients with major depressive disorder who don’t find a medication or therapy that works may undergo electroconvulsive therapy (ECT), also known as shock therapy. But researchers have also been studying intravenous ketamine — a powerful anesthetic that’s also long been used as an illicit ‘party’ drug — as a potential antidepressant. They say the results of a new study were surprising. “I have to say it was a wow,” said principal investigator Dr. James Murrough, director of the Depression and Anxiety Center for Discovery and Treatment at Icahn School of Medicine at Mount Sinai in New York City. That isn’t to say that ketamine is superior to ECT, Murrough cautioned. This study wasn’t assessing that. What it does mean is that in this comparative effectiveness trial, “by the numbers ketamine performed very well,” Murrough said. The findings apply to patients who don’t have psychosis but have treatment-resistant major depression that has not been helped through two or three earlier medications. The main takeaway, Murrough said, is that for doctors treating these patients, ketamine is something they could consider as an alternative to ECT. “The take home from this study is there’s another option that’s in that conversation now that really wasn’t before in a meaningful way,”…  read on >  read on >

Only 13% of American adults understand the purpose of the 988 Suicide and Crisis Lifeline nearly a year after its widely publicized launch, a new survey from the Pew Charitable Trusts shows. “There is an opportunity and a need for state and local leaders to launch inclusive awareness campaigns in the months ahead,” lead researcher and Pew senior manager Tracy Velázquez said in a statement, CNN reported. “The federal government’s most recent investment into 988 shows a commitment to building a strong crisis care infrastructure in the country — one that is critically important, given the many people experiencing mental health and substance use issues,” Velázquez added. The 988 line began last year after it was changed from 1-800-273-TALK. It was previously called the National Suicide Prevention Lifeline. Pew surveyed more than 5,000 adults in April, finding that once people knew about the 988 crisis line, about 7 in 10 said they were somewhat or highly likely to use it. Respondents also had some concerns about where calling the line might lead them. About 2 in 5 of those surveyed worried that calling 988 would lead to police arriving at their home, being forced to go to the hospital, being charged for services they couldn’t afford or having other people learn about the call. Race played a part in the results: Twice as many white…  read on >  read on >

About 7 in 10 American parents are concerned that social media trends related to appearance and editing apps and filters are harming their children’s body image, a new survey shows. Among those polled, about 69% of parents expressed worry about these editing apps and filters, which can completely change the look of someone’s face and body. This may make them appear to meet some supposed standard of beauty. Also, about two-thirds said that trends related to diet and exercise also had a negative influence, according to the survey results released May 23 by the On Our Sleeves Movement for Children’s Mental Health, from Nationwide Children’s Hospital in Columbus, Ohio. A young person’s feelings about their body can affect their mental health, said Erin McTiernan, a contributor to On Our Sleeves and a pediatric psychologist at Nationwide Children’s. “Those concerns are valid,” McTiernan said about parents’ strong response to the survey questions. “Social media has some great benefits for kids, especially in the areas of entertainment and social connection. But when it comes to body image, there are some things that we know can have a negative impact.” Making comparisons Children may compare themselves to these unrealistic standards or feel this is how they should be because of the numbers of “likes” they get on social media for a certain look, McTiernan said. “We know that…  read on >  read on >
