Texas woman dies from brain-eating amoeba after cleaning sinuses with tap water
A Texas woman died from an infection caused by a brain-eating amoeba days after cleaning her sinuses using tap water, according to a Centers for Disease Control and Prevention case report.
The woman, an otherwise healthy 71-year-old, developed "severe neurologic symptoms" including fever, headache and an altered mental status four days after she filled a nasal irrigation device with tap water from her RV's water system at a Texas campsite, the CDC report said.
She was treated for primary amebic meningoencephalitis (PAM) — a brain infection caused by Naegleria fowleri, often referred to as the "brain-eating amoeba,"the CDC said. Despite treatment, the woman experienced seizures and died from the infection eight days after she developed symptoms, the agency said.
Lab tests confirmed the amoeba in the woman's cerebrospinal fluid, according to the report.
The CDC said the infection usually occurs after "recreational water activities" but noted that cleaning sinuses with non-distilled water is also a risk factor for developing PAM.
An investigation conducted by the agency found that the woman had not recently been exposed to fresh water but had done the nasal irrigation using non-boiled water from the RV's potable water faucet "on several occasions" before her illness.
The potable water tank, the investigation found, was filled before the woman bought the RV three months ago and could have contained contaminated water. The investigation also concluded that the municipal water system, which was connected to the potable water system and bypassed the tank, could have caused the contamination.
The agency stressed the importance of using distilled, sterilized or boiled and cooled tap water when performing nasal irrigation to reduce the risk of infection and illness.

St. Francis Hospital recognizes National Gun Violence Awareness Day
HARTFORD, Conn. (WTNH) — Friday is National Gun Violence Awareness Day. Guns are listed as the leading cause of death for children and teens in the United States and more than 100 Americans are killed with guns every day, according to the Centers for Disease Control and Prevention. Governor Lamont advocates for more funding for gun violence prevention Saint Francis Hospital hosted a ceremony and speaking program Friday morning to honor those who have been impacted by gun violence and raise awareness of the important day. 'On Jan. 29, 2013, Hadiya Pendleton, a 15-year-old high school sophomore was shot and killed while standing in harsh park in Kenwood, Chicago,' hospital president Valerie Powell-Stafford said. 'Her death drew a national spotlight and stands as a reminder of how easily and abruptly gun violence can disrupt lives.

RFK Jr.'s policies will make America's maternal mortality rates worse
The American College of Obstetricians and Gynecologists rightly criticized Health and Human Services Secretary Robert F. Kennedy Jr.'s announcement at the end of last month that his department will no longer recommend the Covid vaccine for pregnant women. Covid was the leading cause of maternal mortality in 2021, and the ACOG correctly pointed out that the vaccine is safe and that it provides needed protection for expectant mothers and their unborn children. The decision by Kennedy's agency to delete the recommendation that pregnant women be vaccinated against a virus that was recently the leading cause of maternal death should prompt us to ask: Where are pregnant women in Kennedy's 'Make America Healthy Again' plan? As a maternal health physician, public health expert and equity leader, I'm as unhappy as ACOG is with the specific decision the HHS has made to stop recommending the Covid vaccine for my pregnant patients. Contracting Covid during pregnancy increases the risk of complications, including death. But I'm even more outraged and alarmed by something else HHS has done on Kennedy's watch: omit maternal mortality review committees (MMRCs) and perinatal quality collaboratives (PQCs) from the new structure of HHS. Maternal mortality review committees show us what is killing mothers and how we can stop it. Perinatal quality collaboratives give us the tools to act. They help hospitals and providers implement lifesaving solutions. These programs are not bureaucratic add-ons, but the main reason our nation has made progress in reducing maternal deaths. And yet, in a new proposed budget, programs run by the Centers for Disease Control and Prevention, such as the pregnancy risk assessment monitoring system, maternal mortality review committees and perinatal quality collaboratives are conspicuously missing. Together, these programs have led to measurable improvements in maternal outcomes across the country. From 2021 to 2023, the U.S. saw statistically significant decreases in maternal mortality. That's not a coincidence — it's the result of a national, coordinated strategy rooted in evidence and accountability. The removal of this infrastructure is more than a policy shift — it's a dismantling of the very system that allowed us to fight back against a maternal health crisis. And the stakes are especially high for Black women and rural mothers, who face the greatest disparities in maternal outcomes. Without MMRCs, we lose the ability to track those disparities. Without PQCs, we lose the mechanism to fix them. In smaller hospitals, especially, quality improvement isn't a given — it's something PQCs make possible by helping teams implement patient safety bundles that might otherwise remain unused. Forty-six states and six U.S. territories have MMRCs supported by a CDC grant. This funding provides support to perform case reviews of maternal deaths, while the CDC provides the infrastructure, including a database that allows the results of such reviews to be aggregated. Data from MMRCs in 38 states in 2020, for example, showed that the leading cause of pregnancy-related deaths was mental health conditions, inclusive of suicide and accidental overdose, and 84% of those deaths were deemed preventable. Those findings gave rise to federal programs such as the maternal mental health hotline which, I'm thankful, will continue to be supported in the proposed HHS budget. The CDC also provides funding to support 36 state-based PQCs. This is an example of how the programs work together: In Louisiana, our maternal mortality review identified obstetric hemorrhage as our leading cause of pregnancy-related deaths in 2018. As a result, the Louisiana Perinatal Quality Collaborative (LaPQC) through the reducing maternal morbidity initiative and the safe births initiative worked to implement the AIM obstetric hemorrhage patient safety bundle. As a result, Louisiana mothers experiencing hemorrhage saw a 39% decrease in severe maternal morbidity (SMM), with a 58% decrease among Black women. These aren't anecdotes. They are blueprints for saving lives. Like the decision to stop recommending the Covid vaccine, if the decision to remove these programs from the budget stands, we will reverse course. The U.S. already has the highest maternal mortality rate among high-income countries. Removing these programs is likely to make the national crisis worse. We cannot allow that. My message to policymakers is simple: You can't 'Make America Healthy Again' if you ignore the risks of pregnancy and childbirth. Reinvest in the programs that are working. Fund the programs that show us why mothers are dying and what to do to keep more mothers alive. Preserve the public health infrastructure that has already started to move the needle in the right direction. If we as a country fail to act, then more mothers will die — and the tragic part is, we'll know we had the tools to prevent it. This article was originally published on

The 9 best deodorants and antiperspirants for men in 2025, according to testers and dermatologists
If you haven't realized by now, men's deodorant isn't one size fits all. You have the option between deodorant and antiperspirant, then the choice of solids, gels, sprays or wipes, plus 24-, 48- or 72-hour protection. It gets kind of overwhelming to think about, but there's a purpose for every deodorant option out there. To help you break down the madness so you can choose the best deodorant and/or antiperspirant for you, we turned to a panel of experts, including dermatologists and in-house testers. For starters, we asked about the difference between a deodorant and an antiperspirant, and why you might want both in one product. "Deodorants mask the odor, while antiperspirants prevent you from sweating," said Dr. Monika Kaniszewska, a board-certified dermatologist based in Chicago. So, in order to stop stink and sweat, you'll want a combination of both. With feedback from our experts, we compared dozens of products, from extra-strength sweat-stopping antiperspirants to gentle, all-natural, aluminum-free deodorants, to find the best of the best. Whether you're looking for an all-natural deodorant for men, designed to stop the stink without harsh chemicals, or the best antiperspirant for men to block sweat completely, this list has you covered. Best deodorant for men overall for 2025 Other top deodorants for men we recommend for 2025 What to consider when buying the best deodorant for men How we chose the best deodorant for men FAQs Meet our experts Update, June 6, 2025: We checked all product prices, availability and specs. Our number one pick for the best men's deodorant remains unchanged. (back to top) (back to top) While some people use the terms "antiperspirant" and "deodorant" interchangeably, these are two different things. According to Dr. Camila Antia, a Houston-based dermatologist, "Antiperspirants control sweat by blocking sweat glands, usually with aluminum compounds. Deodorants, on the other hand, primarily mask odor and may contain antimicrobial agents. Some products are combination antiperspirant deodorants, providing both functions." The difference means that if excessive sweating is your main concern, antiperspirants are better suited for you than a standard deodorant. You can tell whether a product is an antiperspirant by looking for the term "antiperspirant" on the label. Furthermore, in the United States, antiperspirants are regulated by the FDA as an over-the-counter drug and have drug information panels on their labels. Many deodorants claim to be all-natural, but if you're shopping in the United States, this term means little in terms of cosmetics. However, many deodorants advertised as "natural" are free from parabens, which are preservatives often found in many cosmetics. Some research has suggested that parabens can disrupt human hormone production, but the Centers for Disease Control and Prevention says "health effects from environmental exposure to low levels of parabens are unknown." Aluminum-based antiperspirants: Various aluminum compounds are used in antiperspirants because they work to reduce the release of sweat by physically blocking it from exiting the sweat glands, chemically inhibiting sweat release, or a combination of the two. Sodium bicarbonate (baking soda): Baking soda acts as a deodorizer, partially by killing the bacteria that cause body odor. While baking soda is nontoxic, it can cause skin irritation. Avoid it if you have sensitive skin. Fragrances: In the United States, companies are not required to list ingredients added to products to create scents, but fragrances can cause allergic reactions. Since there's no way to identify which chemical caused the reaction, those who've had allergic reactions to fragrances should choose unscented deodorants. Solid: Solid deodorants are just that — solid rather than liquid or gel-like. Solids are often bright white, which can lead to stains on darker clothing. Invisible solid: Invisible solids are identical to other solids except they go on clear instead of white. Roll-on deodorant: Roll-on deodorants are liquid and often have a smooth, gel-like consistency. You apply these deodorants by rubbing a roller ball at the end of a tube against your skin. The biggest downside is that they can leave you feeling a little wet and sticky for a few moments until they're completely absorbed by your skin. Spray: Spray, or aerosol, deodorants are applied by spraying under your armpits, like you would a spray-on sunscreen. Gel: Some deodorants come in gel form but are applied like a solid deodorant rather than a roll-on. These deodorants don't leave stains, unlike most solids. However, they can take a while to dry. Wipe: Wipes can be an easy way to reapply deodorant throughout the day if you need to remove some sweat in the process. Most don't contain antiperspirant and tend to be on the expensive side. Many deodorants and antiperspirants are labeled "extra-strength." This usually means that they have more of whatever active ingredient (typically aluminum) included to keep you dry and smelling fresh. Figuring out whether you need an extra-strength product is a matter of trial and error. Different deodorants and antiperspirants claim to last different amounts of time. Most last for a minimum of a day, while others claim to last up to three or four days. While these results vary, you might want to choose a longer-lasting product if you forget to reapply or don't shower every day. Since deodorants and antiperspirants need to be reapplied at least once every couple of days, choosing one that you can afford to purchase on a regular basis is important. Deodorants advertised as "all-natural" and ones from luxury brands tend to be more expensive, yet may or may not contain sweat- or smell-blocking ingredients. More popular brands can sometimes be bought in bulk online, which can drive down the cost per stick. When evaluating the price of a product, make sure to check not only how many sticks of deodorant are included, but also how many ounces of product are in each stick, since each product can vary in size. (back to top) We evaluated dozens of deodorant and antiperspirant products and spoke to board-certified dermatologists, in addition to reviewing the scientific literature. We chose products that received positive reviews online that provided a breadth of features, depending on the category. We rated each product based on variables such as ingredients, cost, longevity, scents and what the product stated it was designed to do. (back to top) Yes, says Antia. "Generally, antiperspirant deodorants are considered safe for most people. They work by reducing sweat production and often contain aluminum compounds. Some individuals may be sensitive to certain ingredients, so it's advisable to check for any allergic reactions." Nope. "The strength of deodorants is not necessarily determined by gender," Antia says. "Some products may be marketed with specific scents or packaging for men or women, but the effectiveness is more related to the formulation." So if you like that lilac-scented deodorant you sniffed at the drugstore, go for it. Although the conventional wisdom is that you should apply deodorant after your morning shower, that's not when it's most effective to do so. Antia says that "it's best to apply antiperspirant to clean, dry skin at night. Sweat gland activity decreases during sleep. Nighttime application allows the active ingredients, such as aluminum-based compounds, more time to penetrate and block sweat ducts. It also allows the product to dry thoroughly and decreases the chance of irritation." That depends. Different products claim to last a variety of times: anywhere from one to three or four days. Antia says that while these claims can be true, your results depend far more on your lifestyle and biology. "Whether a deodorant can last for 48 hours depends on factors such as individual sweat rates, activity levels and product composition." No and no. Dr. Natalie Hone, a dermatologist in Houston, says aluminum is needed for a deodorant to have antiperspirant properties. "Aluminum-free deodorants work by neutralizing odor but do not reduce sweat like antiperspirants." So while you may want to avoid aluminum if you're allergic, don't worry about it giving you cancer. While it's been suggested that aluminum can cause various ailments and disorders, most notably Alzheimer's disease and breast cancer, there is no evidence that antiperspirants cause any health concerns, including no link between antiperspirant use and breast cancer. "If excessive sweating or persistent odor becomes a concern, it's advisable to consult with your dermatologist," Hone said. "They can help determine if there's an underlying medical issue or recommend suitable solutions." If over-the-counter solutions aren't working for you, there is still hope, she said. "There are several treatment options for patients with severe sweating, also known as hyperhidrosis. Options include topical towelettes, oral medications and even neurotoxin injections to the area."
