Bacterial infection common in women may actually be an STI: Study
In a new study published Wednesday, researchers found that treating male partners may prevent the recurrence of bacterial vaginosis.
Bacterial vaginosis results from an imbalance in the vagina's bacteria, causing symptoms of discolored discharge, a 'fishy' odor, vaginal itching and a burning feeling when peeing, though not all women who have BV will show symptoms.
According to the Cleveland Clinic, the infection is the most common vaginal problem for women ages 15 to 44.

In the study, published in The New England Journal of Medicine, researchers in Australia observed 164 monogamous heterosexual couples to study whether treating male partners would reduce the recurrence of BV in the female partner.
In the control group, the women who had bacterial vaginosis received antibiotics, while the men did not receive any treatment. In a second study group, both partners received treatment.
In the control group in which men did not take antibiotics, 63% of women redeveloped bacterial vaginosis within 12 weeks after taking oral medication.
In comparison, just 35% of women whose partners also received treatment experienced reoccurrence.

'Our trial has shown that reinfection from partners is causing a lot of the BV recurrence women experience, and provides evidence that BV is in fact an STI,' said Professor Catriona Bradshaw at Monash University.
The study calls for a new approach to the way the infection is classified and treated, finding that male-partner treatment may prevent the recurrence of bacterial vaginosis.
'We've suspected for a long time that it's a sexually transmitted infection (STI), because it has a similar incubation period (after sex) to most STIs and is associated with the same risk factors as STIs like chlamydia, such as change in sexual partner and not using condoms,' said Dr. Lenka Vodstrcil, one of the study's authors.
Practitioners still do not treat BV as an STI, but if it were to officially be classified as one, it would surpass chlamydia as the most common.

What sharing a bottle of wine with your spouse every night really means for your health
Since they first met in 2009, Sarah Wellband and her partner James have settled into a nightly routine which involves, at the minimum, sharing the best part of a bottle of wine together. 'We have a gin and tonic, followed by two or three glasses of wine with dinner and watching TV,' says Wellband, a 62-year-old remedial hypnotherapist. Such a routine, seven nights a week, would probably amount to somewhere between 46 and 62 units of alcohol per week, depending on whether that third glass of wine was consumed – far more than the NHS recommended guidelines of 14 units. However, Wellband says that the drinking habits of her and her 70-year-old partner are far from an issue. Instead, she insists that they form an important part of their general wellbeing. '7pm is news and a drink time,' she says. 'It signals the end of the day and time to wind down and catch up with each other. The routine is more important than the alcohol, but it helps. We are well aware of our limits and will leave a glass rather than finish it for the sake of it, but we just find it a nice way to end the day.' Recently however, the potentially long-term harm from excessive daily drinking has been brought once more to the spotlight. Earlier this year, a study found that consuming more than eight alcoholic drinks a week increases your risk of incurring the brain degeneration commonly linked with dementia, while former TV executive Martin Frizell recently gave an interview about his wife Fiona Phillips's battle with early-onset Alzheimer's, and openly mused as to whether their habit of drinking a bottle of wine a night in their younger years had been a contributing factor. Yet the link between alcohol and chronic diseases is a little more nuanced than often portrayed. While excessive drinking has been identified as a direct cause of at least seven types of cancer and a known risk factor for dementia, the exact risk varies considerably from person to person. As Debbie Shawcross, professor of hepatology and chronic liver failure at King's College London, explains, women have far lower levels of the enzyme that breaks down alcohol compared with men, which makes them more susceptible, and studies have even shown that women are more likely to display signs of 'leaky gut' – a term which characterises greater intestinal permeability, meaning that toxins are more likely to leak out into the bloodstream – following a binge than men. An alcohol 'binge' is characterised as more than six units (a standard-sized glass of wine contains 2.1 units) in a single session for women and eight units for men. Some people do also carry gene variants that improve alcohol metabolism, allowing them to knock back the booze with no apparent ill effects – and Wellband says that she and her partner never get drunk on their nightly routine – while your diet can also be a contributing factor. 'Environmental, social and lifestyle factors also play a role,' says Shawcross. 'For example, being overweight or having an unhealthy diet rich in ultra-processed foods can increase the risk of alcohol harm on the body.' On average though, sharing a bottle of wine every night with your spouse isn't the greatest thing for your long-term health. Here's the very latest on how this amount of daily booze can affect your body, and what some of the UK's leading experts advise in terms of how to still enjoy alcohol in a safer way. What are the effects on the brain? As Anya Topiwala, a senior clinical researcher at the University of Oxford, points out, half a bottle of wine a night works out at a minimum of 35 units per week for white wine and 42 units if you're only drinking red wine, which generally contains more alcohol per volume. 'If sustained, I would say there is a high likelihood of this negatively impacting your brain and memory,' she says. This comes from studies she's conducted which have found that people drinking more than 14 units per week, or seven medium-sized glasses of wine, have small total brain volumes, greater age-related shrinkage of the hippocampus – the brain's memory hub and one of the areas particularly impacted by Alzheimer's – and faster cognitive decline. 'Alcohol is a neurotoxin,' says Topiwala. 'Put simply, it kills brain cells. Additionally, heavy drinking often leads to a deficiency in vitamin B1 which can also damage the brain.' But it's not all doom and gloom. By reducing the amount you drink, even by a glass or two per week, it's possible to mitigate and even reverse some of these issues, something which Topiwala has witnessed first-hand in her practice as an old-age psychiatrist, with various patients seeing their short-term memory and recall improving after reducing their alcohol intake. 'I can think of many patients who have experienced a cognitive benefit from cutting down,' she says. What are the effects on the liver? Between 90 and 98 per cent of the alcohol you consume is broken down by your liver, making it one of the organs most acutely impacted by booze. Based on her own clinical and research knowledge, Shawcross says that people consuming half a bottle of wine per night will be particularly at risk of developing fatty liver – a condition where the liver becomes progressively clogged up with harmful visceral fat. Over time, this makes you more prone to cirrhosis or scarring and liver cancer. But she says that cutting down, even slightly, would undoubtedly help. 'There is no safe level of drinking, but if you didn't drink at all for two to three nights per week, there would be even more benefits,' says Shawcross. 'For example, you'd see a reduction in the amount of liver fat, as measured on a scan.' Shawcross is keen to point out that if you are not getting drunk, as noted by Wellband and her partner, it is not necessarily a sign that you have a protective gene variant which allows you to metabolise alcohol more quickly, limiting its damaging effects on the body. She explains that people can develop a tolerance to higher amounts of alcohol because the liver has a different group of enzymes which kick into action when there are consistently large amounts of alcohol in the bloodstream. This isn't a good thing, as harmful fat and other forms of damage will still be accruing, but it makes you less aware of alcohol's effects. 'When this different set of enzymes is consistently activated, it means you need to drink more alcohol to feel its effects,' she says. What is the effect on the heart? Consuming more than 7.5 units of alcohol a day – or most of a bottle of wine by yourself – is thought to increase risk of hypertension, where the pressure on your blood vessels is too high. Over time, this may lead to other issues such as arrhythmia or abnormal heart rhythms. 'Alcohol increases blood pressure and if this is untreated, it puts strain on the heart,' says Shawcross. Studies have indicated that hypertension risk seems to increase proportionally with the amount you drink. So a glass of wine per day will still make you more susceptible than not drinking at all, but is certainly less problematic than two or three glasses. What are the effects on the muscles and bones? As John Kiely, a researcher at the University of Limerick, puts it, alcohol accelerates many of the ravages of ageing, from loss of muscle to reduced coordination and increased vulnerability to twinges, strains and other injuries. In particular, if you've consumed half a bottle of wine one night, it probably isn't a wise idea to hit the gym or do some vigorous gardening the next day as the alcohol will impair your immune system's ability to reach and repair any damaged muscles or tendons, leaving you feeling all the more tender and sore. If you are drinking half a bottle of wine on a regular basis, Kiely suggests that you will be much more likely to get injured. There's also the matter of the progressive muscle and bone loss which most of us experience as part of ageing. Studies have long shown that regular, heavy drinking in middle age accelerates bone weakness and interrupts normal cycles of muscle repair, making it harder to hold onto the strength we have, as we age. 'An otherwise healthy diet and lifestyle will reduce these risks but persistent heavy drinking drives progressively accumulating issues that a healthy lifestyle alone can't fully counteract,' says Kiely. 'For example, alcohol lowers levels of key hormones [for muscle growth] like testosterone and growth hormone, while cortisol, a key stress hormone that drives muscle breakdown, rises. And because alcohol also reduces the absorption of calcium and suppresses the activity of bone-building cells, you're likely to have a faster decline in bone density, making your bones more fragile.' The good news is that such effects do not seem to be as pronounced with moderate drinking. 'A single glass of wine a night for women, or two for men, is unlikely to cause measurable harm to muscle health and little risk for bone health,' says Kiely. 'This is particularly the case for people who stay active and eat well.' What is the effect on how quickly you age? Drinking too much has long been associated with faster signs of visible ageing, such as more wrinkles, saggy skin and a duller complexion, but we now know that consuming half a bottle of wine each night actually ages you at the DNA level. In 2022, Topiwala carried out a study showing that consuming more than 17 units of alcohol per week – or around eight standard glasses of wine – causes damage to the tips of chromosomes, known as telomeres, which play an important role in keeping your DNA stable. 'Alcohol directly damages DNA, causing breaks and mutations,' says Topiwala. 'This is thought to explain why alcohol increases cancer risk.' What you can do to limit the risks While all of this may seem like something of a downer, all these risks are most apparent when it comes to heavy drinking. Research has also repeatedly shown that we can still enjoy alcohol throughout mid and later life and minimise the negative impacts on our health through having a few non-drinking days each week, eating well and exercising, and, particularly, consuming alcohol with a meal wherever possible. For example, one study of more than 300,000 people in the UK found that people who predominantly drank alcohol with meals had a 12 per cent lower risk of premature death from cardiovascular diseases and cancer, compared with those who mainly consumed their alcohol on its own. But for Wellband, like many others, the idea of changing the nightly drinking routine is not something that she and her partner are willing to contemplate, at least for now. 'We have no intention of changing our ways,' she says. 'Although I was adopted I have since discovered my birth mother is 82 and still drinks two or three glasses of wine every night so I'm following her lead. My partner and I have gradually reduced the amount we drink – on the rare occasion we go out for lunch we'll now have a glass of wine each rather than a bottle. Living on a farm with horses and other animals means that we have to be fit and active, but equally we enjoy our evening drinks and would be loath to give them up.' How can you adjust your drinking habit? For anyone looking to try to switch to drinking less, Dr Richard Piper, chief executive at Alcohol Change UK, offers the following guide: Try to spread your week's alcohol across more days Our bodies and our minds are grateful for any breaks we can give them. Pepper your week with several alcohol-free days. Aiming for fewer than five units in a single day will mean your overall weekly consumption should drop. Replace with lower-strength or alcohol-free alternatives There is a wonderful range and availability of alcohol-free alternatives in shops, pubs and bars now, which are improving year on year. Our taste testers particularly recommend the Mash Gang ranges of alcohol-free beers (Journey Juice and Lesser Evil were given a 5/5 rating), while Nozeco Spritz is an alcohol-free cocktail which stands out from others on the market.

Tick-borne Rocky Mountain spotted fever spreading in Canada
Quebec has reported a case of the potentially deadly tick-borne disease Rocky Mountain spotted fever that was likely acquired in Ontario or Quebec. The disease was reported in dogs in Ontario earlier this year. Here's what you need to know about preventing, identifying and treating the disease. What is Rocky Mountain spotted fever? Rocky Mountain spotted fever is a disease caused by the bacteria Rickettsia ricketssii. It's named for the fact that it was first identified in Rocky Mountain valleys of Idaho and Montana in the 1890s. Symptoms in humans can include fever, headache, nausea or vomiting, stomach pain, muscle pain and lack of appetite. The disease is named for the red rash that develops two to four days after the fever begins. The rash can range from pinpoint dots to red splotches. The disease can be treated with the common antibiotic doxycycline, and most people make a full recovery. But it can be deadly in five to 10 per cent of cases in the U.S. even with treatment, reports the U.S.-based Cleveland Clinic. Without treatment, one in four people die of the disease. WATCH | Researchers try to curb tick populations as diseases spread: Dogs can also get Rocky Mountain spotted fever. Dr. Scott Weese, director of the Centre for Public Health and Zoonoses at the University of Guelph, said symptoms in dogs include fever, malaise, enlarged lymph nodes, loss of appetite and muscle aches that make the animals reluctant to move. The rash can sometimes be seen inside the dog's mouth. As with humans, the disease can be deadly in dogs, and Weese said one of the first dogs identified with the disease in Ontario died of it. How is it transmitted? It can't be transmitted from person to person. It's only acquired from tick bites — typically the American dog tick (Demacentor variabilis), which is found from eastern Alberta to Nova Scotia, especially in the southern parts of those provinces. Weese says despite its name, it doesn't target dogs specifically, but a variety of large mammals, including humans. Previously, people didn't worry about American dog ticks because they didn't carry Lyme disease, which people get from the blacklegged or deer tick. "Now we're having to change our tune a little bit, realizing that this tick might not be as benign as we thought around here," Weese said. Like black-legged ticks, American dog ticks are found in grassy and wooded areas. Ticks can also hitch-hike between dogs or from dogs to humans — something Weese thinks happened to him the other day with his own dog at home. Other ticks that can carry Rocky Mountain spotted fever include the Rocky Mountain wood tick (Dermacentor andersoni) and the brown dog tick (Rhicephalus sanguineus). Where is the disease found? The U.S. sees 6,000 cases per year, especially in North Carolina, Tennessee, Missouri, Arkansas and Oklahoma, the Cleveland Clinic reports. In Canada, the disease was known but rare in B.C., with an incidence of one case per 500,000 people in 2019. WATCH | Tick-borne illnesses are on the rise. Here's what to look out for: There have been occasional cases of Rocky Mountain spotted fever reported in other parts of the country. A 73-year-old woman was diagnosed with the disease in 2023 after travelling from Saskatchewan to Ontario, and being in contact with her son's two dogs in Ottawa. The Ottawa doctors who saw the case said the disease's expansion north into areas where it hadn't been seen before was likely linked to milder winters and hotter, drier summers linked to climate change, which allow ticks to expand their range. Earlier this year, a cluster of cases in dogs was linked to Long Point Provincial Park on Lake Erie in Ontario. Weese said such a large group in a small area was a surprise. "That would suggest that this is quite well-established, at least in some areas." LISTEN | Rocky Mountain spotted fever found at Long Point: This week, Dr. Alex Carignan, a microbiologist and infectious disease specialist with the regional health authority in Estrie, Que., reported a "recent" case in the province's Eastern Townships. In an update Wednesday, he wrote that the further investigation showed that the infected patient had recently spent time both in the region of Ontario where the dogs were infected and in an area of the Eastern Townships with a lot of ticks. That makes it uncertain where the patient picked up the infection. Carignan wrote that it remains important to keep an eye out for the disease in Quebec and for local health professionals to be able to recognize it. Dr. Isaac Bogoch, an infectious disease specialist based at Toronto General Hospital, said the Ontario dog infections and the detection of Rickettsia bacteria in ticks north of the border had shown that the disease was already in Canada. "The real question is how much of it is here and what's the geographic distribution." He added that other tick-borne diseases such as Lyme disease, anaplasmosis and babesiosis have spread more widely over recent years as shorter, warmer winters allow tick populations to push north. What should people do to protect themselves and their pets? Both Bogoch and Weese recommend people take precautions to avoid being bitten by ticks. This can include staying on trails and away from places such as long grass and leaf litter; wearing long sleeves, long pants and insect repellent when possible while in areas where ticks might be; checking for ticks on themselves and their dogs after visiting such areas; and removing ticks promptly if found. Weese said people with dogs are at higher risk because they're more likely to walk in areas with higher risk of tick exposure and because dogs can sometimes bring ticks into homes in their fur. Giving dogs oral or topical tick preventive medications can greatly reduce the risk of exposure, Weese said. However, it doesn't replace other measures, and may not be as effective with Rocky Mountain spotted fever as it is with Lyme disease, since the former is transmitted more quickly. Bogoch said health-care workers should be aware there are tick-transmitted diseases beyond Lyme that they should look out for, so that suspected cases of Rocky Mountain spotted fever can be treated immediately. Weese recommended that if people or their pets fall ill after visiting wooded or grassy areas that might have ticks or Rocky Mountain spotted fever, they should mention the possible exposure to their doctor or vet to ensure prompt diagnosis and treatment. He also noted that while people should be aware of these diseases, they're still rare in Canada. "Canada hasn't been the hot spot for any of these ticks or their diseases in the past, and they won't be the hot spot compared to the U.S. But we're a hotter spot than we were."

Gut-Lung Axis: Clinical Relevance for Pulmonology
Emerging insights into the gut-lung axis continue to open new possibilities for managing chronic respiratory diseases, from cystic fibrosis (CF) in the youngest patients to chronic obstructive pulmonary disease (COPD) in older adults. Despite growing evidence linking gut health to respiratory disease pathogenesis, these findings are not yet ready for routine clinical application. Still they underscore the value of discussing diet and nutrition with patients as part of broader strategies to optimize overall health. 'For most lung diseases, the majority of the literature on gut health that changes lung disease pathogenesis is from research studies,' explained Rachel Scheraga, MD, pulmonologist and critical care physician at Cleveland Clinic in Cleveland. Although studies have explored gut metabolites and lung microbiome changes associated with gut dysbiosis, they cannot yet lead to evidence-based dietary interventions for patients without further clinical trials in humans. But there are some practical gut-lung connection that currently impact practice. For instance, when gut dysfunction is suspected, pulmonologists at Cleveland Clinic refer patients to gastroenterology to rule out other contributing conditions such as reflux. This is an especially important step in patients with end-stage lung disease awaiting transplant, given the link between poor gut health and an increased risk for transplant rejection. 'The main gap is for the pulmonologist to determine what context the gut may be contributing to either the acute or chronic disease and the proper time to screen for gut dysfunction,' Scheraga said. 'I believe it is important to start with translational research to determine the cause and effect of the contribution of gut dysfunction to lung disease. Once it is determined what specifically the gut is doing to cause lung disease progression, then clinical research can be performed to modify this factor and see if the lung disease improves.' Mechanistic Insights: Linking Gut Microbes to Lung Outcomes At the Geisel School of Medicine at Dartmouth in Hanover, New Hampshire, George A. O'Toole, PhD, is exploring the association between the gut microbiome and CF. 'Linking the gut to the lung is a complex process that requires a team of researchers in the clinic and at the bench,' he shared. 'Bench scientists need to understand the clinical issues, and clinicians can help translate observations from patient care into laboratory studies to better define these connections. This area of research must be collaborative — and pulmonologists play a key role.' While many studies have documented associations between gut dysbiosis and chronic lung disease, the mechanisms remain poorly defined. O'Toole points to several key questions: How are gut microbes influencing the airway? Is the effect direct, with microbial metabolites traveling to the lung and modulating immune responses? Or are gut microbes shaping immune cells in the gut, which then migrate to the airway? O'Toole's work in CF in pediatric populations has validated links between gut pathogens such as Escherichia coli with Pseudomonas aeruginosa airway infections in infants and children. This work has been done in close collaboration with Juliette Madan, MD, MS, and Julie Sanville, DO, physician-scientists at the Dartmouth Hitchcock Medical Center, Lebanon, New Hampshire. 'In our CF model, we established the link between gut and airway, and we know this link is driven by propionate,' he said. 'I'm excited to understand how propionate tunes the airway response. We are also developing probiotic strategies that I think could have great potential.' 'Understanding this connection lets us develop new means to help address airway disease. We have the opportunity to improve patient outcomes.' Nutrition: A Modifiable Factor As diet and nutritional status are recognized as modulators of lung health through the gut-lung axis, personalized nutrition has potential to be as complementary to pharmacologic therapy, said Inês Brandão, PhD, Head of Research at Centro de Apoio Tecnológico Agro Alimentar, Castelo Branco, Portugal, a Portugal-based research and innovation center focused on the agri-food sector. Adequate protein intake, anti-inflammatory, fiber-rich diets, and the use of probiotics, prebiotics, or symbiotics can help support asthma, COPD, and other respiratory diseases, she said, adding the need for well-designed clinical trials, validated biomarkers, and multidisciplinary care teams. 'Encouraging patients to adopt anti-inflammatory, fiber-rich diets and consider probiotic or prebiotic supplementation may support gut microbiota health and reduce lung inflammation,' she said. 'This represents, beyond any doubt, low-risk and cost-effective strategies.' 'Moving forward,' Brandão said, 'building a shared understanding through collaboration between researchers, clinicians, and nutrition experts will be essential to provide clear, practical guidance for pulmonologists.' Brandão, O'Toole, and Scheraga reported having no relevant financial relationships.
