Will These 2 Home Remedies Help Your Sore Throat?

MONDAY, Dec. 18, 2017 (HealthDay News) — Down go another two worthless home remedies for strep throa..

MONDAY, Dec. 18, 2017 (HealthDay News) — Down go another two worthless home remedies for strep throat.

Neither sugarless gum nor probiotics help to treat the symptoms or speed up recovery from a sore throat caused by bacterial infection, a new clinical trial reports.

Doctors had thought that gum sweetened by xylitol, a sugar substitute, might coat the throat and prevent the spread of strep bugs, said lead researcher Michael Moore of the University of Southampton in England.

And some doctors thought probiotics could stimulate the immune system and crowd out harmful strep bacteria, he added.

Probiotics, some suggested, might even help fend off viral infections that cause sore throat, said Moore, a professor of primary health care research.

But his team found no significant benefit from either in a four-year clinical trial involving almost 700 people suffering from sore throat.

Folks with strep should stick with proven remedies to ease their pain, Moore concluded.

"Simple painkillers taken by mouth or medicated lozenges that are anesthetic and antiseptic can provide some short-term symptom relief," Moore said.

Most sore throats are caused by viruses. But about 20 percent are caused by bacteria, most often streptococcus, Moore said.

Only a laboratory test can confirm strep throat, according to the U.S. Centers for Disease Control and Prevention.

But antibiotics are frequently overused to treat sore throat. About 70 percent of sore throat patients receive antibiotics, even though these drugs do nothing to treat a viral infection and aren't effective in soothing strep soreness, according to the Infectious Diseases Society of America.

Concerns about increasing antibiotic resistance led Moore and his team to test these two home remedies.

Clinical trial participants were divided into two groups, one testing the usefulness of gum and the other testing probiotics. Probiotics are good bacteria thought to have health benefits.

Gum chewers were given sticks sweetened with either xylitol (a birch sugar) or sorbitol, or told not to chew gum.

Xylitol has been shown to inhibit bacterial growth and coat the throat wall; the sweetener sorbitol has no such effect, but was included to test whether simply generating more saliva would help soothe the throat.

The probiotic group was provided capsules that contained either actual probiotics or a placebo.

The upshot: Neither xylitol gum nor probiotics provided effective treatment of sore throat symptoms.

"There's no shortage of remedies put forward for sore throats," said Dr. Jack Ende, president of the American College of Physicians. "It's the old axiom that if there are a lot of treatments suggested, no single one actually works."

People with a simple sore throat should try gargling with salt water, downing a spoonful of honey or taking aspirin, ibuprofen or acetaminophen to help them feel better, Ende advised.

Also, look for typical cold symptoms. If you're sneezing or coughing, you probably don't have strep throat, he said.

"Wait it out, and do not go to your doctor's office," Ende said. "He or she has nothing to offer, and all you'll do is potentially infect others in the waiting room."

People with more serious symptoms — a high fever or swollen glands — are more likely to have strep and should go to the doctor, Ende said.

Your doctor might prescribe antibiotics for your strep throat, but don't be surprised if you aren't provided any, Ende and Moore said.

"It gets better on its own. It really does," Ende said. "Antibiotics shorten the course by a day or two, but that's all."

However, the CDC says antibiotics are prescribed for strep to prevent rheumatic fever.

The study was published Dec. 18 in the journal CMAJ.

Monkeypox: First deaths outside Africa in Brazil and Spain

Brazil and Spain have reported their first monkeypox deaths.

A 41-year-old man in Brazil became the first fatality from the virus outside Africa. Spain announced two deaths soon afterwards – the first in Europe.

Last week, the World Health Organization (WHO) declared the monkeypox outbreak a global health emergency.

But infections are usually mild and the risk to the general population is low.

On Friday Brazil’s health ministry said the victim there had suffered from lymphoma and a weakened immune system, and “comorbidities aggravated his condition”.

Brazil has so far reported 1,066 confirmed cases and 513 suspected cases of the virus. Data from Brazil’s health ministry indicates that more than 98% of confirmed cases were in men who have sex with men.

Shortly afterwards, Spain’s health ministry confirmed Europe’s first death from the virus – a patient who suffered from encephalitis.

A second death linked to monkeypox was confirmed by Spanish authorities on Saturday.

The health ministry said that of 3,750 monkeypox patients with available information, 120 or 3.2% had been hospitalised.

According to the US Centers for Disease Control and Prevention, there are 21,148 cases worldwide.

The monkeypox virus is a member of the same family of viruses as smallpox, although it is much less severe and experts say chances of infection are low.

It occurs mostly in remote parts of central and west African countries, near tropical rainforests.

Health officials are recommending people at highest risk of exposure to the virus – including some gay and bisexual men, as well as some healthcare workers – should be offered a vaccine.

Last week, WHO director general Dr Tedros Adhanom Ghebreyesus said declaring the outbreak a global health emergency would help speed up the development of vaccines and the implementation of measures to limit the spread of the virus.

Dr Tedros said the risk of monkeypox is moderate globally, but high in Europe.

But, he added, “this is an outbreak that can be stopped with the right strategies in the right groups”. The WHO is issuing recommendations, which it hopes will spur countries to take action to stop transmission of the virus and protect those most at risk.

Covid: Woman caught virus twice within record 20 days

A 31-year-old healthcare worker caught Covid twice within 20 days – the shortest-known gap between infections, Spanish researchers have claimed.

Tests show the woman was infected with two different variants – Delta in late December and then Omicron in January.

This shows that even if you have had Covid before, you can still be infected again even if fully vaccinated, the researchers say.

Reinfections in the UK require 90 days between positive tests.

Based on that definition, health officials say nearly 900,000 people have potentially been infected twice with Covid up to the start of April.

It is difficult to pin down an exact number, because only whole genome sequencing can confirm the infections are caused by different strains, and very few positive tests go through this process.

The Spaniard did not develop any symptoms after her first positive PCR test, but less than three weeks later she developed a cough and fever which prompted her to take another test.

When the tests were analysed further, they showed the patient had been infected by two different strains of coronavirus.

In a presentation at the European Congress of Clinical Microbiology and Infectious Diseases, study author Dr. Gemma Recio said the case highlighted that Omicron can “evade the previous immunity acquired either from a natural infection with other variants or from vaccines”.

She said: “In other words, people who have had Covid-19 cannot assume they are protected against reinfection, even if they have been fully vaccinated.

“Nevertheless, both previous infection with other variants and vaccination do seem to partially protect against severe disease and hospitalisation in those with Omicron,” added Dr Recio, from the Institut Catala de Salut, Tarragona in Spain.

She said monitoring reinfections in people who were fully vaccinated was important, and would help the search for variants which evade vaccines.

Covid reinfections rose sharply in December 2021 after the much more infectious Omicron variant emerged, and there was another increase when a slightly different version of it, called BA.2, appeared in early March.

Before that, 1% of all cases recorded in the UK were labelled as second infection – but that has now gone up to 11%.

Most are likely to be people infected by the Alpha or Delta variants and then infected again by the more contagious Omicron.

Scientists predict that eventually everyone will catch Covid twice, and probably many more times over the course of their lifetime.

Poverty, crime linked to differences in newborns’ brains

Poverty and crime can have devastating effects on a child’s health. But a new study from researchers at Washington University School of Medicine in St. Louis suggests that some environmental factors influence the structure and function of young brains even before babies make their entrances into the world.

A study published online in the journal JAMA Network Open found that MRI scans performed on healthy newborns. At the same time, they slept indicated that babies facing social disadvantages such as poverty tended to be born with smaller brains than babies whose mothers had higher household incomes.

MRI scans of full-term newborns born to mothers living in poverty revealed smaller volumes across the entire brain — including the cortical grey matter, subcortical grey matter and white matter — than found in the brains of babies whose mothers had higher household incomes.

The brain scans, conducted only a few days to weeks after birth, also showed more miniature folding of the brain among infants born to mothers living in poverty. Fewer and shallower folds typically signify brain immaturity. The healthy human brain folds as it grows and develops, providing the cerebral cortex with a more extensive functional surface area.

A second study of data from the same sample of 399 mothers and their babies — this one published online in the journal Biological Psychiatry — reports that pregnant mothers from neighbourhoods with high crime rates gave birth to infants whose brains functioned differently during their first weeks of life than babies born to mothers living in safer neighbourhoods.

Functional MRI scans of babies whose mothers were exposed to crime displayed weaker connections between brain structures that process emotions and structures that help regulate and control those emotions. Maternal stress is believed to be one of the reasons for the weaker connections in the babies’ brains.

“These studies demonstrate that a mother’s experiences during pregnancy can have a major impact on her infant’s brain development,” said Christopher D. Smyser, MD, one of the principal investigators. “Like that old song about how the ‘knee bone is connected to the shin bone,’ there’s a saying about the brain that ‘areas that fire together wire together.’ We’re analysing how brain regions develop and form early functional networks because how those structures develop and work together may impact long-term development and behaviour.”

Babies in the study were born from 2017 through 2020, before the COVID-19 pandemic. Smyser, a professor of neurology, paediatrics and radiology, said that babies are fed when they arrive for scans because they tend to fall asleep after eating to scan newborns during the first few weeks of life successfully. They are then snugly swaddled into blankets and a device that helps keep them comfortable and still. The brain scans take place while they sleep.

In the study involving the effects of poverty, the researchers focused on 280 mothers and their newborns. First author Regina L. Triplett, MD, a postdoctoral fellow in neurology, had expected to find that maternal poverty — referred to in the paper as a social disadvantage — could affect the babies’ developing brains. But she also expected to see the effects of psychosocial stress, which includes measures of adverse life experiences and anxiety and depression.

“Social disadvantage

affected the brain across many of its structures, but there were no significant effects related to psychosocial stress,” Triplett said. “Our concern is that as babies begin life with these smaller brain structures, their brains may not develop as healthy as the brains of babies whose mothers lived in higher-income households.”

In the second study, which implicated living in high-crime neighbourhoods as a factor in weaker functional connections in the brains of newborns, first author Rebecca G. Brady, a graduate student in the university’s Medical Scientist Training Program, found that unlike the effects of poverty, the results of exposure to crime were focused on particular areas of the babies’ brains.

“Instead of a brain-wide effect, living in a high-crime area during pregnancy seems to have more specific effects on the emotion-processing regions of babies’ brains,” Brady said. “We found that this weakening of the functional connections between emotion-processing structures in the babies’ brains was robust when we controlled for other types of adversity, such as poverty. It appears that stresses linked to crime had more specific effects on brain function.”

Reducing poverty and lowering crime rates are well-established goals in public policy and health. And the researchers believe protecting expectant mothers from crime and helping them out of poverty will do more than improve brain growth and connections in their babies. But if social programs that aim to help people reach their full potential are to succeed, the researchers said the policies must focus on assisting people even before they are born.

“Several research projects around the country are now providing money for living expenses to pregnant mothers. Some cities have determined that raising pregnant mothers out of poverty is good public policy,” Smyser said. “The evidence we’re gathering from these studies certainly would support that idea.”
