Girls who said they often weigh themselves were more likely to have depression, weight concerns and self esteem issues, researchers found.

“The findings from this study suggest that for some teens and young adults, self-weighing is associated with poor psychological health and it is important that we use caution when recommending self-weighing or any strategy for weight control that may not be beneficial for some individuals,” said lead author Carly R. Pacanowski, of the University of Minnesota in Minneapolis.

The 10-year study tracked almost 2,000 adolescents, most of whom were female. They were surveyed, weighed and measured in 1998, when they were in middle or high school and then again in 2003 and 2008 as they transitioned into young adulthood.

Overall, few participants agreed that they weighed themselves "often," the researchers reported in the Journal of Nutrition Education and Behavior.

But among women whose reports of self-weighing increased over time, so did their weight concern and symptoms of depression, which can be predictors of eating disorders, researchers found.

For men, as reported self-weighing increased, so did concern about weight, but other psychological variables did not change.

Parents, teachers, aunts, uncles, and friends may want to ask about self-weighing to gather more information if a teen seems overly concerned with her weight, Pacanowski told Reuters Health by email.

“Self-weighing may be easier to talk about initially than self-esteem or depressive symptoms,” Pacanowski said. “From there, getting in touch with a healthcare provider would be the next step.”

Obesity-prevention programs should avoid worsening body dissatisfaction and weight concern by understanding how behaviors like self-weighing affect teens, she said.

Pacanowski also cautioned that the new study can't say whether self-weighing causes low self-esteem, or low self-esteem causes teens or young adults to weigh themselves more frequently.

The new study is also limited by the use of the subjective term "often" to gauge the frequency of self-weighing over time, said Jessica LaRose, a health behavior and policy researcher at Virginia Commonwealth University in Richmond, who was not part of the new study.

“Thus, in terms of clinical implications for pediatricians, we can't determine using these data whether there is a specific threshold or frequency of self-weighing in this age group that could serve as a signal to explore mental health symptoms and well being,” LaRose told Reuters Health by email.

The woman in her late 50s, who suffered from serious underlying health problems, died on Sept. 4 at a Tucson, Arizona-area hospital, said Pima County Health Department spokesman Aaron Pacheco.

    Federal health officials have confirmed deaths in Texas and California from the strain of Salmonella Poona, and another 91 people have been hospitalized.

The outbreak has made 418 people ill across 31 states, with 52 percent of those infected being younger than 18, according to the U.S. Centers for Disease Control and Prevention (CDC).

    The agency said the outbreak was caused by tainted cucumbers produced in Baja California, Mexico, and distributed by Andrew and Williamson Fresh Produce in San Diego. Company officials said they have voluntarily recalled all of its Limited Edition brand label cucumbers sold between Aug. 1 and Sept. 3.  

    About 1.2 million people annually become ill from salmonella, with about 450 cases resulting in death, the CDC reports. Symptoms may include headache, stomach pain, diarrhea, nausea and sometimes vomiting within 72 hours of ingesting a contaminated food or drink, Arizona health officials said.

The Agriculture Department (USDA) said in a statement that it would consider using the method if there are no other ways to kill flocks within 24 hours of infections being detected.

The agency wants to cull infected flocks within a day to prevent the virus from spreading. Nearly 50 millions chickens and turkeys died from bird flu or were culled from December through June in the country's worst animal disease outbreak on record.

Shutting down ventilation systems in poultry houses "essentially bakes the birds to death," the Humane Society of the United States said.

“We shouldn’t compound the problems for birds by subjecting them to a particularly miserable and protracted means of euthanasia," said Michael Blackwell, the Humane Society's chief veterinary officer.

The Agriculture Department said the method was a "necessary alternative" because of the need to eradicate the virus.

According to the agency, its first choices for culling infected poultry will be suffocating them with foam or in chambers filled with carbon dioxide, methods widely used last spring.

More than two months have passed since the last infection. However, officials are preparing for a potential resurgence this fall because wild ducks, which can carry the virus, will be migrating.

It takes about 30 to 40 minutes for birds to die from heat stress during the process, known as ventilation shutdown, said T.J. Myers, the Agriculture Department's associate deputy administrator for veterinary services. He said the agency had never used the method.

"We certainly hope we don't have to use this, or any depopulation methods," Myers said.

The government is trying to improve its response after farmers complained the agency had moved too slowly in killing and disposing of infected flocks. Delays can contribute to the spread of the disease.

Separately, the Agriculture Department has allowed Harrisvaccines to become the first company to produce a vaccine to fight bird flu. The agency plans to build a stockpile of vaccines in case there is another outbreak. It has not given any company permission to market a vaccine.

"Really the only buyer right now would be the U.S. government," Harrisvaccines spokesman Joel Harris said.

Researchers questioned caregivers of newborns at Staten Island University Hospital in New York City about sleep safety and found 53 percent of them disagreed with use of pacifiers – which are in fact linked to a lower risk of SIDS – and 62 percent believed in swaddling infants – which is tied to an increased SIDS risk.

It’s possible that new parents may have a hard time discarding advice from their own parents or grandparents even though recommendations about sleep safety have changed considerably from one generation to the next, lead study author Dr. Sarah Varghese said by email.

“There is a certain power surrounding 'traditional' knowledge,” said Varghese, now at Emory University and Children’s Healthcare of Atlanta. “Both parents and health care professionals need to stay up-to-date on recommendations.”

Nationwide, SIDS kills about four babies out of every 10,000 live births, down from about 130 in 10,000 in 1990, according to the Centers for Disease Control and Prevention.

Despite the dramatic decline in death from SIDS since 1992, when the American Academy of Pediatrics (AAP) announced that babies should be placed on their backs to sleep, SIDS in recent years has remained the third leading cause of infant mortality, the authors report in the Journal of Perinatology.

Almost four years ago, the AAP issued new infant sleep guidelines for prevention of SIDS and other sleep-related deaths; the guidelines encouraged breastfeeding, pacifier use, and firm crib mattresses, and cautioned against blankets and pillows and bed-sharing.

The study by Varghese and colleagues, while small, suggests that at least some parents may not have absorbed these most recent recommendations.

The researchers questioned 121 caregivers, including parents and grandparents, of newborns delivered in 2013, asking how strongly they agreed or disagreed with recommended infant sleep safety practice.

Most participants strongly agreed on the importance of using a safety approved crib, avoiding exposure to smoke and getting routine childhood vaccinations.

But most of them disagreed with guidance against swaddling and using home monitors, as well as recommended pacifier use.

Some caregivers may avoid pacifiers because they have concerns about dental issues, while others may worry that it could interfere with breastfeeding, the study authors note. The AAP recommends starting pacifier use when babies are about three or four weeks old, after they are successfully breastfeeding.

Swaddling with blankets or specially designed wraps can increase the risk of infant death, but some nurses still swaddle infants in the hospital and teach new parents how to do it themselves, the authors note. Some caregivers believe swaddling can soothe infants and make it easier for them to sleep.

Only 61 percent of participants recalled being taught about sleep safety by a health care provider.

The study was small, limited to English-speaking participants and included primarily white caregivers, which may limit how much the findings apply to a more diverse population, the researchers acknowledge.

Even so, the findings highlight the challenge of conveying safe sleep practices to parents who may be overwhelmed by too much advice, said Dr. Michael Goodstein, a neonatologist at York Hospital WellSpan Health in York, Pennsylvania and a member of the AAP task force on SIDS.

“Even if parents have been made aware of safe sleep information, there may be competing and conflicting information and advice available from multiple sources including books, magazines, family and friends, TV shows and the Internet, as well as many different health care providers,” Goodstein, who wasn’t involved in the study, said by email.

NPH insulin comes as an insoluble mixture of crystals and liquid and must be resuspended before injection.

Researchers at Perugia University in Italy wanted to know what difference it would make if patients didn’t resuspend their NPH insulin by tipping the insulin pen 20 times before injection - and if they didn’t shake it by tipping it back and forth, whether it would matter how they held the needle during the injection.

As it turned out, everything mattered.

One of the researchers, Dr. Geremia B. Bolli, told Reuters Health he was surprised by “the high variability of effects on lowering of blood glucose depending as to whether the NPH pen is properly resuspended or not, and (if it’s not resuspended), even great differences depending on the position of the pen, i.e., horizontal, vertical with tip up or down.”

“The same NPH appears as a different insulin in each of these conditions,” Bolli said by email.

Compared with resuspending NPH insulin, not shaking the pen before injecting could result in lower insulin levels in the blood (if you inject with the needle flat or pointing up) or higher insulin levels (if you inject with the needle facing down).

Your body would also feel the effects of insulin earlier if you injected with the needle down without shaking it first or later if you injected it flat or needle up without shaking it first.

This could result in your blood sugar rising above desired levels sooner (needle flat or pointed up) or later (needle pointed down) when you don’t resuspend the NPH insulin by shaking the pen first.

The research team reported in the journal Diabetes Care that insulin levels could vary by as much as 23% and blood sugar control could vary by as much as 62% depending on whether NPH insulin is shaken before injecting, or not.

“For the users of NPH and also of the pre-mixed insulin (rapid+NPH) it is important to resuspend carefully prior to injection,” Dr. Bolli concluded. “This will reduce variability of NPH effects a lot.”

Dr. Satoru Yamada from Kitasato Institute Hospital, Tokyo, Japan, who was not involved in this study, told Reuters Health by email that the results show it's very difficult to have stable efficacy with NPH insulin.

Yamada advises doctors to select long-acting analogs rather than NPH itself.

Bolli agrees that it’s great if patients can afford the newer glargine and detemir forms of insulin, but he points out that for many patients, these alternatives are beyond their means. And for these patients, the message is clear: always resuspend your NPH insulin before injecting.

Researchers examined U.S. survey data on racial attitudes from 1993 to 2002 and linked the responses to death records through 2008, to explore the impact of prejudice on mortality. Altogether they had data from almost 11,000 people living in 100 communities nationwide.

By 2008, 1,651 people died, accounting for about 15 percent of the participants.

Living in a community with higher levels of anti-black prejudice increased residents’ overall odds of death by 24 percent when mortality risk was assessed independent of individual and neighborhood socioeconomic factors and individually held racial attitudes, the study found.

“Racial prejudice compromises health for the community as a whole,” said lead study author Yeonjin Lee, a sociology researcher at the University of Pennsylvania.

The findings challenge a widespread belief that only victims of racial prejudice can be harmed by prejudice, Lee said by email. Instead, the study found prejudice was harmful for the health of both black and white participants.

“The current finding - that adverse effects of structural racism were not specific to blacks - show that structural discrimination not only damages the low-status group members but also majority group members who live in the same community,” Lee added.

Structural racism is when social systems, social forces, institutions, ideologies, and processes interact to create and maintain racial and ethnic inequities, according to John A. Powell writing in the open-access Berkeley Law Scholarship Repository (bit.ly/1gycM4T).

The survey questions that Lee and colleagues analyzed asked whether black people had worse jobs, income or housing due to less in-born ability to learn; and whether black people lacked motivation to get out of poverty.

Additional questions touched on both black and white individuals, asking if one race was more or less intelligent or lazy than the other and whether there should be laws against marriages between the two races.

One limitation of the study is its reliance on survey participants to honestly answer questions about race because some people may try to provide what they think are socially acceptable responses even if they are not truthful, the researchers acknowledge in the American Journal of Public Health.

Researchers also lacked data on some factors that can influence mortality, such as how people eat and whether they smoke or drink.

While the paper doesn’t prove prejudice causes premature death, it’s possible that residents of communities with less racial tension may have a greater ability to band together to advocate for policies and services that help foster a healthier neighborhood, the authors suggest.

Researchers call this social capital, and they found higher levels linked to a 17 percent reduction in community-level mortality. Social capital was lower in communities where racial prejudice was higher, the study found.

It’s also possible that communities with high levels of racial prejudice may create a hostile living environment that triggers certain stress responses in the body that can negatively impact health and mortality, said David Williams, a professor of public health and African-American studies at Harvard University in Boston.

Many little indignities – like being treated disrespectfully or with fear or mistrust – can create a hostile environment in a community and add up to enough stress to trigger a biological response to racial prejudice, said Williams, who wasn’t involved in the study.

Over time, heightened stress can lead to more abdominal fat, heart disease and the buildup of plaque in the coronary artery, all of which have the potential to hasten death.

“Little indignities can predict mortality,” Williams said. “Sometimes we think it takes a big event, but if you are exposed to a series of chronic ongoing little indignities it all adds up.”

Congress adjourned for the weekend with an Oct. 1 government shutdown deadline fast approaching and no clear plan from Republican leaders for extending funding for federal agencies.

Many conservative Republicans had called for the stop-gap spending measure to deny funding to Planned Parenthood, but others in the party, aware of Democratic opposition, had said this would increase the likelihood of a second government shutdown in two years.

House Speaker John Boehner, trying to release some steam from his caucus, chose to delay consideration of a spending bill vote and put the stand-alone defunding bill to a vote, along with a separate measure aimed at banning abortions that involve live births.

Both measures passed easily, largely on party lines.

Planned Parenthood faces allegations, which it denies, of improperly selling fetal tissue from abortions. The non-profit group said Internet videos that have inflamed anti-abortion sentiment among Republicans "falsely" portray its participation in tissue donation programs for medical research.

Several House Republicans said the two bills passed on Friday would be blocked by Senate Democrats, and stronger action to stop Planned Parenthood funding may be necessary.

"I think you still need to continue to look at the funding mechanism as a potential vehicle to stop the murders," said Representative Bill Flores of Texas, who heads a group of 172 House conservatives.

During debate of the two bills, Democratic Representative Carolyn Maloney of New York said the legislation "attempts to criminalize legal medical care and punish women by rolling back reproductive choices."

Representative Richard Hudson of North Carolina said he was concerned that anti-Planned Parenthood policy provisions in the spending bill would prompt a shutdown without stopping the practices.

And Representative Roger Williams of Texas said, "There are "people like me who can’t find a way to vote for anything that funds Planned Parenthood."

The White House again called on Republicans to enter budget talks to ease automatic spending constraints, but said a short funding extension was still needed.

"I would not envision a long extension of funding at current levels, but rather enough time for Congress to finally convene the talks, reach an agreement and implement it," White House Spokesman Josh Earnest said.
