Artificial bloodstream vessels mimic rare faster aging disease

Lab-grown bloodstream vessels provide platform for studying premature aging syndrome along with other rare illnesses.

Biomedical engineers have become miniature human bloodstream vessels that exhibit most of the signs and symptoms and drug reactions connected with Hutchinson-Gilford Progeria Syndrome – an very rare genetic ailment that causes signs and symptoms resembling faster aging in youngsters.

We’ve got the technology can help doctors and researchers screen potential therapeutics for that disease more quickly, with the aim of eventually developing a platform for personalized screening. The process also provides a different way to review other rare illnesses and may provide insights into treating cardiovascular disease within the seniors.

The research was printed online within the journal Scientific Reports.

“Among the drugs presently prescribed with this disease extends patients’ lives by three several weeks, and that is been considered a significant task,” stated Leigh Atchison, a doctorate candidate in biomedical engineering at Duke College and first author from the study. “They are searching for something that will extend lifespan by a couple of several weeks. It’s that devastating.”

Hutchinson-Gilford Progeria Syndrome – or just progeria for brief – is really a non-hereditary genetic disease the result of a single-point mutation within the genome. It’s so rare and thus deadly there are presently no more than 250 known cases worldwide.

Progeria is triggered with a defective protein known as progerin that builds up outdoors of the cell’s nucleus instead of becoming a part of its structural support system. This will cause the nucleus to defend myself against an abnormal shape and inhibits being able to divide. The resulting signs and symptoms look similar to faster aging, and affected patients usually die of cardiovascular disease introduced on by weakened bloodstream vessels before age 14.

“Progeria is not considered hereditary, because nobody lives lengthy enough to transfer,Inch stated George Truskey, the R. Eugene and Susie E. Goodson Professor of Biomedical Engineering at Duke. “You will find presently 75 children in numerous studies, that is amazing because of the rarity from the disease. However with 15 compounds into consideration for trials, the mathematics just ultimately will not exercise. You cannot try many of these drugs or various mixtures of them in humans, so we are wishing our platform will give you another way to check them.”

Bloodstream vessels take time and effort to simulate as their walls have multiple layers of cells, such as the endothelium and also the media. The endothelium may be the innermost lining of bloodstream vessels that interacts with circulating bloodstream. The press is created mostly of smooth muscle tissues which help control the flow and pressure from the bloodstream within.

Researchers still find it the degeneration of those smooth muscle tissues that ultimately results in the center disease and failure that so frequently kills patients with progeria. But since there are so couple of individuals with progeria, it’s very hard to study within the patients themselves.

“Since it is this type of hard disease to review, we would have liked to find out if we’re able to produce a platform using human cells more precisely represents the condition after which apply it drug testing,” stated Atchison. “Therefore we attempted to develop miniature artificial bloodstream vessels using caused pluripotent stem cells produced from cells obtained from patients with progeria.”

The program labored. In only four days of growth, the engineered bloodstream vessels exhibit most of the signs and symptoms observed in individuals with the condition – signs and symptoms that easy cell cultures haven’t been in a position to recreate. The bloodstream vessels also respond much like pharmaceuticals, revealing nuances into how current therapies will work.

As the bloodstream vessels demonstrated improved function following a week to be dosed by having an analogue of rapamycin, a medication referred to as everolimus, calcification along with other signs and symptoms of coronary disease continued to be. This means that the medication is enhancing the smooth muscle tissues are more effective, although not remedying the actual signs and symptoms.

“This is exactly why our bodies might be so helpful,” stated Atchison. “It might inform us just what the drug does inside a faster, more high-throughput manner, and whether we want another treatment to deal with other facets of the condition.Inch

The success may aid study regarding other rare illnesses, too.

“The main factor we are pleased with is this fact works as a evidence of principle for developing a vascular type of an uncommon disease within the laboratory to higher comprehend it and hopefully create a therapy,” stated Truskey.

The study might also provide understanding of why some seniors people become especially vulnerable to cardiovascular disease. Many heart patients have proven exactly the same buildup from the progerin protein, so researchers believe there might be a hyperlink backward and forward conditions.

You will find, obviously, limitations towards the new artificial bloodstream vessels. They aren’t linked to any outdoors organs, nor could they be baked into the complicated biology of the living individual.

“We simply produced smooth muscle tissues from progeria patients within this study, however their endothelial cells might play a significant role too,Inch stated Atchison. “When we can incorporate endothelial cells produced from the patients’ own cells in to the model too, only then do we can produce a more personalized testing platform of these patients.”

These studies was based on the nation’s Institutes of Health (UH3TR000505, R01HL126784), the nation’s Science Foundation (GRFP Grant #1106401), the Maryland Stem Cell Research Fund, and also the Progeria Research Foundation.

Inadequate sleep raises diabetes type 2 risk in youngsters

child sleeping with clock
New information investigates the hyperlink between sleep duration and risk markers for diabetes type 2 in youngsters.
Could less than one hour rest influence children’s chance of developing diabetes type 2? New research suggests so.

Within the U . s . States, one in three individuals are believed to build up diabetes type 2 at some point within their lifetime.

The condition affects men and a lot of women, but based on the latest data in the Cdc and Prevention (CDC), over 5,000 youthful individuals are identified as having diabetes type 2 each year.

Researchers from St. George’s, College based in london within the Uk attempted to check out the potential outcomes of sleep duration and diabetes type 2 risk in youngsters.

They was brought by St. George’s professor Christopher G. Owen, and also the findings were printed within the journal Pediatrics.

Because the authors from the new information explain, the potential associations between the size of sleep and also the risk markers for diabetes type 2 haven’t been sufficiently studied.

Studying sleep duration and diabetes risk

Prof. Owen and colleagues examined 4,525 multiethnic children aged between 9 and ten years, all whom existed within the U.K.

They required the kids body measurements, including height, weight, bloodstream pressure, and bioimpedance – a stride of methods well your body resists electric energy, which provides insights into body composition.

They required bloodstream samples and tested the kids predisposition to diabetes type 2 utilizing a plasma glucose test.

The scientists also tested the kids amounts of lipids, insulin, and also the hemoglobin HbA1c, amongst others.

Insulin may be the hormone that regulates bloodstream sugar. An imbalance within the body’s lipids – or excess fat – is regarded as involved with cardiovascular complications for those who have diabetes type 2. Finally, HbA1c continues to be proven to become a marker of these fat impairment.

Sleep duration was calculated while using information supplied by the kids. They reported around the time they sometimes go to sleep and also the time they awaken on the school day. They confirmed these details inside a subgroup of kids, utilizing an accelerometer-based sleep tracker.

Prof. Owen and team given your body measurements, along with the cardiovascular and diabetes type 2 risk markers, into multilevel straight line regression models, modifying for possible confounders for example sex, age, ethnicity, socioeconomic background, and also the effect their schools may have around the results.

Just one hour a smaller amount of sleep raises risk

Overall, the kids rested for 10.5 hrs every night, typically. The research found no associations with cardiovascular risks, like the hemoglobin HbA1c.

However, the research did discover that the shorter the sleep duration, the greater the kids amounts of excess fat – a connection previous research has also highlighted.

Furthermore, the study uncovered an identical inverse correlation between sleep duration and levels of insulin, insulin resistance, and bloodstream sugar levels.

Actually, just one hour of less sleep considerably elevated diabetes type 2 risks, for example bloodstream sugar and insulin resistance.

“The finding of the inverse association between sleep duration and T2D [diabetes type 2 risk markers in early childhood is novel,” the authors conclude. “Intervention studies are necessary to establish the causality of those associations, that could give a simple technique for early T2D prevention.”

Prof. Owen and colleagues include that growing the mean sleep length throughout the week day by less than half an hour can lead to home loan business bmi (Body mass index) of .1 kilograms per square meter and home loan business insulin resistance.

These bits of information suggest growing sleep duration could provide a simple method of reducing amounts of excess fat and diabetes type 2 risk from early existence […]. Potential benefits connected with elevated sleep in early childhood might have implications for health in their adult years.”

Prof. Cristopher G. Owen

The CDC suggest that children between 6 and 12 years of age is deserving of between 9 and 12 hrs rest every evening.

Mental health programs in schools – growing body of evidence supports effectiveness

School-based mental health programs can achieve large figures of kids, with growing proof of effectiveness in improving mental health insurance and related outcomes, based on an investigation review within the September/October publication of the Harvard Overview of Psychiatry. The journal is printed by Wolters Kluwer.

“This review provides evidence that giant-scale, school-based programs could be implemented in a number of diverse cultures and academic models in addition to preliminary evidence that such programs have significant, measurable results on students’ emotional, behavior, and academic outcomes,” write J. Michael Murphy, EdD, of Massachusetts General Hospital and colleagues.

School-Based Programs Concentrate on Stopping Mental Health Issues

An believed 13 % of kids and adolescents worldwide have significant mental health issues for example anxiety, disruptive behavior disorders, attention-deficit/hyperactivity disorder, and depression. Particularly if not treated, these disorders frequently persist into their adult years, with lasting effects on the majority of facets of existence.

Through the years, many programs happen to be made to deliver preventive mental health services in schools, where children and teenagers spend a lot of time. Substantial research now implies that school-based mental health interventions could be broadly implemented and can result in population-wide enhancements in mental health, health, educational, and social outcomes.

Dr. Murphy and colleagues identified and examined school-based mental health programs which have been implemented on the massive and also have collected data on specific mental health outcomes. The authors estimate the eight largest programs have arrived at a minimum of 27 million children during the last decade.

The interventions vary within their focus, methods, and goals. The biggest program, known as “Positive Behavior Interventions and Supports” (PBIS), concentrates on positive social culture and behavior support for those students. The 2nd-largest program, known as “Buddies,” aims to lessen anxiety and also to educate skills for managing feelings and dealing with stress – not just to children, but additionally to teachers and parents.

The majority of the school-based mental health interventions specified for to pay attention to mental health promotion or primary prevention for those students within the school some programs also target students at high-risk of mental health issues. The majority of the programs happen to be implemented across school districts, although some happen to be introduced around the condition or national level.

Available research provides “moderate to strong” evidence these interventions work well to promote good mental health insurance and related outcomes. For instance, studies of Buddies have reported reductions in anxiety, while PBIS has proven improved studying scores and less school suspensions. Other individuals have proven benefits for example reducing bullying in school one intervention has been associated with lower rates of drug abuse in youthful their adult years.

The authors explain that college-based mental health interventions happen to be studied almost solely in high-earnings countries – even though about 80 % from the global population of kids reside in low- and middle-earnings countries (LMICs). There is however evidence that this can be altering, since three from the eight largest programs happen to be implemented “to scale” in LMICs. One of these simple, known as “Skills for Existence,” continues to be running on the national basis in Chile for over a decade.

“Data teams of growing quality and size are opening new possibilities to evaluate the amount that preventive interventions for child mental health, delivered at scale, can lead to improving health insurance and other existence outcomes,” Dr. Murphy and colleagues conclude. With ongoing data collection and new evaluation frameworks, they feel that college-based mental health programs have the possibility to “improve population-wide health connection between generation x.Inch

Rotavirus vaccines still reduce diarrhea hospitalizations, medical costs in US kids

Following the development of routine childhood vaccination against rotavirus, a standard reason for diarrheal illness, greater than 380,000 children prevented hospitalization for diarrhea from 2008 to 2013 within the U.S., thus saving an believed $1.2 billion in direct medical costs. The estimates, from new research printed within the Journal from the Pediatric Infectious Illnesses Society, provide additional evidence for that substantial impact of routine rotavirus vaccination. Additionally they suggest increased advantages of immunization if other prevented costs may be considered.

For that study, researchers examined data from community and academic hospitals in 26 states, concentrating on hospitalizations for acute gastroenteritis among children under five years old, to estimate the outcome of rotavirus vaccination nationwide. They compared periods pre and post vaccination licensure in the year 2006, excluding the very first year where vaccine coverage rates were low and uneven. Following the beginning of routine rotavirus vaccination in the year 2006, diarrhea hospitalizations decreased by between 31 percent to 55 percent from 2008 to 2013, with greater reductions within the old age. They believed which more than 380,000 hospitalizations for severe diarrhea in youngsters more youthful than 5 were prevented over the U.S. in this six-year period.

“Our findings read the sustained impact and effectiveness from the rotavirus vaccine program,” stated author Eyal Leshem, MD, formerly from the Cdc and Prevention (CDC) during the time of the research and who’s presently associated with the Sackler Faculty of drugs at Tel-Aviv College in Israel. “Growing vaccine coverage likely led to the bigger declines of rotavirus hospitalizations noticed in the old age studied.”

They believed the direct medical financial savings from prevented hospitalizations for diarrhea in infants and youthful children were $1.2 billion nationwide throughout the 2008-2013 period. This amount likely underestimates the general economic impact, the research authors noted, because additional fees, for example individuals connected with averted doctor’s office or er visits for rotavirus disease, weren’t incorporated within their analysis.

In 2015, an believed 73 percent of U.S. children 19-35 several weeks old received rotavirus vaccines, less than rates for other routine childhood vaccines, such as the diphtheria, tetanus, and acellular pertussis (DTaP) vaccine, which 95 % from the children within this same age bracket received, based on CDC. Future research should explore the reason why behind the low than optimal rotavirus immunization rates and interventions to enhance them, Dr. Leshem stated. “Efforts to help increase rotavirus vaccine coverage rates to higher safeguard all children within the U.S. against rotavirus disease should continue.”

Heartbeats could contain the answer to understanding babies&#039 inner world

Research printed in eLife explains how researchers produced a singular new experiment to check how aware babies have their bodies’ internal signals. The opportunity to consciously sense signals from bodies are known as interoception, and a few individuals are more conscious of these signals than the others. These variations between people may influence an array of mental processes, including how strongly you are feeling feelings, your choice-making, and mental health.

“Understanding whenever we start to understand internal signals and just how this ability differs among people is important,Inch stated Professor Manos Tsakiris in the Department of Psychology at Royal Holloway. “Even though we all know that this kind of awareness plays a vital role in cognition in their adult years, we all know absolutely nothing about how exactly its early developmental origins. When and how performs this ability develop? And just how performs this influence who we’re as adults?”

By developing a new test known as iBEATS, they could measure this ability the very first time, and located that babies as youthful as five several weeks old can sense their very own heartbeats.

“When you get butterflies before an address, or feel your heart thumping inside your chest when you are scared, you are utilizing a skill known as interoception.” explains Dr Lara Maister, also at Royal Holloway and also the Warburg Institute, in the School of Advanced Study. “We produced a brand new experiment to find out if youthful children were using interoception therefore we often see when these skills develop.”

In the past, focusing on how babies process internal signals continues to be difficult so far, there’s been not a way to determine interoception in infants. They measured whether infants can discriminate between an animated character relocating synchrony or from synchrony using their own heartbeat. Infants chosen over watch the type which was leaving synchrony, suggesting that even only at that young age, infants are sensitive to their personal interoceptive signals.

The exam also demonstrated that some babies were more sensitive than the others. They measured brain activity and infants who’d proven a powerful preference within the iBEATS task also demonstrated a bigger brain signal referred to as Heart-Evoked Potential (or HEP) that reflects how our minds process signals in the heart. This special interoceptive brain signal got more powerful when babies saw people making negative facial expressions like fear and anger. This means the way babies experience feelings may be carefully associated with their bodies’ responses.

It’s now entirely possible that applying this make sure following babies as they age allows researchers to trace how awareness to internal bodily signals changes as we grow older to aid self-awareness, emotional and cognitive development, and just how these processes effect on mental health once we develop.

Gripe water: Uses along with other treating baby colic

Baby being spoon fed medicine.
Gripe water is a kind of herbal remedy you can use to deal with colic in infants.
Colic is frustrating and frequently frightening for moms and dads with a brand new baby. Otherwise healthy babies with colic can cry not less than three hrs each day for 3 or more days per week without any known cause.

Previously, doctors speculated that colic was brought on by a baby getting stomach discomfort or upset, though this is not proven. Regardless of this, many parents use gripe water, or water combined with herbs, to assuage a baby’s upset stomach, and contains gain popularity with a few parents and supporters of other or herbal medicine.

However, parents thinking about using gripe water like a colic remedy should consult their doctor first.

Contents want to know ,:

  1. What’s colic?
  2. What’s gripe water?
  3. How’s gripe water used?
  4. Risks and benefits
  5. What are the options to gripe water?

What’s colic?

Colic is a disorder that causes a normally healthy and well-given infant to weep intensely for several or even more hrs each day for several or even more days each week. Babies with colic will cry inconsolably and could clench their fists and curl their legs throughout the crying episodes.

Colic starts whenever a baby is about 2-3 days old and could last until an infant is about 4 several weeks old.

Doctors don’t know the precise reason for colic, only one explanation is the fact that some babies tend to be more responsive to stimulation using their atmosphere than the others. This overstimulation causes them stress, which means they are cry.

Because the babies get older, they become able to better soothe themselves and cry less frequently. Other concerns, for example gassiness, may also result in a baby to weep similarly to some baby with colic.

What’s gripe water?

Gripe water is a combination of water, sodium bicarbonate, and herbs that lots of parents use like a fix for colic and stomach upsets in infants.

Most commercially accessible gripe water contains a mixture of the next herbs:

  • fennel
  • ginger root
  • lavender
  • lemon balm

Lots of people using gripe water to assuage colic, believe the colic is because a baby’s stomach troubles or gassiness. Theoretically, these herbs will help ease gas, thus relieving the anguish that’s resulting in the baby to weep.

Gripe water has existed for any lengthy time. It was initially utilized in the 1840s in England to deal with a malarial disease referred to as fen fever. The initial combination of sodium bicarbonate, alcohol, and herbs grew to become well-liked by British moms and nannies through the 1850s. Many believed that gripe water helped calm a picky baby, that is most likely due mainly towards the alcohol.

Today, alcohol isn’t a element of gripe water as scientists realize that giving alcohol to some baby could be very harmful. However, many moms and supporters of herbal supplements still recommend gripe water’s calming impact on babies.


Herbal oils.
Gripe water usually contains a combination of different herbs, including ginger root, fennel, and lemon balm.

Ingredients in gripe water vary by brand. All gripe waters contain a combination of herbs and water. Most include those who are.

Additional ingredients can include a mix of the next:

  • dill oil
  • fennel oil
  • aloe
  • lemon balm
  • ginger root
  • preservatives for freshness

When selecting a gripe water, parents should browse the ingredients listed. Some ingredients to prevent include:

  • gluten, for example wheat
  • milk products
  • sucrose
  • alcohol

Wheat or dairy may cause upset stomach in infants, sucrose can lead to cavities for infants with baby teeth, and alcohol may cause developmental problems in infants.

Also, because gripe water is classed like a supplement and never a medicine, it’s not controlled through the U . s . States Fda (Food and drug administration). Which means that there’s no be certain that any product contains the components for auction on its label.

How’s gripe water used?

Before using gripe water, a parent or gaurdian should first seek advice from a doctor. When the doctor provides the all obvious, parents should then browse the instructions around the gripe water. The instructions includes information about how much gripe water to own baby.

It is advisable to provide the gripe water towards the baby without mixing it with other things, for example breast milk or formula. Most babies such as the flavor of gripe water and won’t spit it, because they will with a few other medications.

Parents should do as instructed as directed through the packaging as well as their doctor.

Risks and benefits

Some formulas of gripe water are usually safe, there are several risks connected with gripe water. Despite its recognition for colic and gas pains, no sufficient research has proven gripe water to work in easing stomach discomfort.

Risks for implementing gripe water can include the next:

  • you can get a hypersensitive reaction
  • it might introduce bacteria right into a baby’s digestive tract
  • if given too early after birth, gripe water may hinder breast-feeding and delay milk supply

So even though many people accept the anecdotal evidence that gripe water may ease their newborn’s cries and support its use, parents should think about if the risks over-shadow any perceived benefits.

Also, since the Food and drug administration don’t approve using gripe water for colic, or other condition, it’s not exposed towards the same rules as medicines.

What are the options to gripe water?

Mother with baby.
Other treatments include applying gentle pressure towards the baby’s belly, and swaddling.

Because so many doctors do caution against using gripe water, parents should consider other ways of soothing their baby.

Other methods include:

  • swaddling the infant
  • applying gentle pressure towards the baby’s belly
  • rubbing the newborn’s belly in gentle circular motions to assist exercise gas
  • if formula feeding, consider switching to some gentler brand as directed with a doctor
  • if breast-feeding, mom might want to alter her diet to get rid of foods that may cause gas or stomach distress, for example spicy food, dairy, and certain vegetables
  • distracting the infant
  • trying white-colored noise

There are more products available, for example gas drops, that some parents use. However, there’s no evidence to demonstrate these goods are more appropriate for the baby than gripe water. Parents must always meet with a doctor before using any herbal remedy.

Regardless of what a parent or gaurdian chooses, the colicky period inside a baby’s existence will pass. Although it may go through like forever as the baby is experiencing colic, colic more often than not resolves by itself when the infant is 3-4 several weeks old.

Do pets really benefit children&#039s health? Large study investigates

happy child with dog
Without effort, we have a tendency to believe that pets benefit our children’s health insurance and emotional well-being. But scientifically, new research suggests, it isn’t really the situation.
An array of small research has recently been suggesting that youngsters who own or communicate with a dog have better physical and mental health. However the largest study available up to now now disproves this hypothesis.

The brand new study was transported out by researchers at RAND corporation, a nonprofit think tank and a part of RAND Health, that is a completely independent healthy policy research program.

The brand new research brings advanced record tools for example double robust regression analyses to study regarding this subject, that the scientists accustomed to take into account additional factors that could influence children’s health instead of pet possession, for example family earnings.

Furthermore, towards the authors’ understanding, this is actually the largest record study to research the hyperlink between children’s health insurance and family dog possession.

The very first author from the study is Jeremy N. V. Miles, and Layla Parast, a statistician at RAND, may be the corresponding author with this research.

Existing research might be biased

Numerous small studies – referenced by Miles and colleagues – have recommended that having a pet may enhance the health insurance and mental well-being of kids.

However, many of these studies, repeat the researchers, have underwent two primary flaws: first of all, they didn’t correctly take into account the so-known as selection bias or even the issue of confounding – that’s, factors for example family earnings that could bias the outcomes.

Statistically, a fix for your problem is utilizing “tendency scores” – a strategy that’s typically accustomed to allow researchers to calculate the probability a thief, for example, may be treated differently according to bias-inducing traits for example age or gender.

But, they stated, couple of from the studies analyzing pets’ impact on the healthiness of children used tendency scores.

A hyperlink between pets and pediatric health?

Miles and colleagues examined data from 2,236 households that owned whether dog or perhaps a cat and compared all of them with 2,955 households that didn’t possess a pet.

They acquired the information in the 2003 California Health Interview Survey – a sizable, population-based, random-digit dialed survey of households.

Laptop computer collected details about the status and health-related and mental behaviors from the families interviewed. Even though laptop computer was transported out over the last years, the 2003 survey was the only person that contained an issue about dog and cat possession.

Miles and colleagues narrowed lower their research to families which had a minumum of one child between 5 and 11 years of age.

Questions assessed through the researchers incorporated queries concerning the all around health and well-being from the child, if the child had received an attention deficit disorder (Attention deficit hyperactivity disorder) diagnosis, and questions if parents had any concerns concerning the mood, feelings, and behavior from the child.

With regards to the record analysis, they used “survey-weighted straight line and logistic regression analyses” with pet possession because the primary variable. Survey weighting is frequently used when statisticians need to estimate regression models according to survey data.

The authors explain that instead of most record studies, designed to use the majority of the available control variables to regulate for possible confounding factors, the present study used a far more advanced record tool known as double robust regression.

This method used tendency scores and weighted the regression models to ensure that “individuals having a pet were comparable with individuals with no pet on all available confounding factors within the data.”

Overall, the scientists accounted in excess of 100 confounding factors that may influence the outcomes, including earnings, vocabulary skills, and the kind of housing they resided in.

Study finds no significant link

The research discovered that, not surprisingly, children in families that owned a dog were in better health insurance and were rather more physically active than children in families with no pet.

In addition, children in pet-owning families were more prone to have Attention deficit hyperactivity disorder, however their parents were not as likely to think about their mood, feelings, behavior, and skill to understand.

However, following the researchers adjusted the findings while using double-robust approach and including tendency scores, the hyperlink between pet possession and children’s health wasn’t any longer statistically significant.

These answers are more reliable than individuals of previous research, the scientists say, as their study may be the largest available up to now.

We’re able to not find evidence that youngsters from families with cats or dogs be more effective off either when it comes to their mental well-being or their health […] Everybody around the research team was surprised – everyone has or increased track of cats and dogs. We’d basically assumed from your personal encounters there would be a connection.”

Layla Parast

Probably the most accurate test for whether pet possession improves children’s health, the authors say, will be a trial in which people are at random assigned a dog and control people are not. This type of randomized trial would need to follow-on the household’s health for ten to fifteen years, the authors say, which is not financially achievable.
