Ticks use static electricity to latch onto hosts: Study
It turns out that some people really are tick magnets.
Researchers have discovered that ticks can defy gravity in their quest to latch onto people and animals. The key is static electricity, just like when someone rubs a balloon and things stick to it.
The study was published in the journal Current Biology. In the first phase of the research, scientists exposed ticks to furry rabbit feet and to acrylic surfaces that each had electrostatic charges.
“Ticks were readily attracted across air gaps of up to several millimeters or centimeters onto these statically charged surfaces,” the authors wrote.
In a second part of the study, the researchers created computer models simulating the electrostatic charges that exist in environments where both ticks and mammals are found. In one simulation, the researchers observed that the body parts of a cow with the most electric charge were the nose, tail, and legs, which are the body parts most likely to be encountered by a tick. They also found that the vegetation near the animal had a strong electric field that is just a few millimeters wide.
In a final phase of the study, the researchers conducted laboratory experiments in which they re-created the electric field conditions from the computer model and successfully lifted some ticks across an air gap, although some ticks did not make the full leap if they were observed to be resisting.
The authors noted that their findings could be applied to developing new tick prevention strategies, such as designing clothing that resists electrostatic charges or spraying livestock.
The study authors reported that they had no conflicts of interest.

Malaria is spreading in the U.S. for the first time in 20 years
, the Centers for Disease Control and Prevention says.
The federal health agency recently issued a nationwide warning to health providers and officials to be on the lookout for symptoms of the potentially fatal illness. Usually, people in the U.S. who get malaria get the disease during international travel.
All five people – four in Florida and one in Texas – have received treatment and are improving, according to the CDC. The case in Texas is not related to the Florida cases, and all occurred in the past 2 months.
Malaria cannot be transmitted from person to person. It is spread by the bite of an infected female mosquito. The last cases of people being infected while in the U.S. occurred 20 years ago, when there were eight cases in Palm Beach County, Fla. The Texas Department of State Health Services said the last time malaria was locally acquired in the state was 1994.
The Florida Department of Health said it was spraying for mosquitoes in the two counties surrounding Sarasota, Fla., where the four cases occurred.
The CDC said the risk of getting malaria while in the United States “remains extremely low.” The agency advised people to protect themselves by taking precautions to prevent mosquito bites, such as wearing insect repellent and wearing long-sleeved shirts and pants. People should also do things to ensure that mosquitoes aren’t around their home, such as getting rid of standing water, which is an environment for mosquitoes to lay eggs.
More than 240 million malaria cases occur annually worldwide, the CDC said, with 95% in Africa. There are 2,000 cases diagnosed annually in the U.S. that are related to international travel. Malaria symptoms are similar to those of other illnesses and include fever, chills, a headache, and muscle aches. If not treated, malaria can be fatal.

Nebulized amphotericin B does not affect aspergillosis exacerbation-free status at 1 year
Topline
Nebulized amphotericin B does not improve exacerbation-free status at 1 year for patients with bronchopulmonary aspergillosis, though it may delay onset and incidence.
Methodology
Investigators searched PubMed and Embase databases for studies that included at least five patients with allergic bronchopulmonary aspergillosis who were managed with nebulized amphotericin B.
They included five studies, two of which were randomized controlled trials (RCTs), and three were observational studies; there was a total of 188 patients.
The primary objective of this systematic review and meta-analysis was to determine the frequency of patients remaining exacerbation free 1 year after initiating treatment with nebulized amphotericin B.
Takeaway
From the studies (one observational, two RCTs; n = 84) with exacerbation data at 1 or 2 years, the pooled proportion of patients who remained exacerbation free with nebulized amphotericin B at 1 year was 76% (I2 = 64.6%).
The pooled difference in risk with the two RCTs that assessed exacerbation-free status at 1 year was 0.33 and was not significantly different between the nebulized amphotericin B and control arms, which received nebulized saline.
Two RCTs provided the time to first exacerbation, which was significantly longer with nebulized amphotericin B than with nebulized saline (337 vs. 177 days; P = .004; I2 = 82%).
The proportion of patients who experienced two or more exacerbations was significantly lower with nebulized amphotericin B than with nebulized saline (9/33 [27.3%] vs 20/38 [52.6%]; P = .03).
In practice
Also, the proportion of subjects experiencing ≥ 2 exacerbations was also lesser with NAB than in the control,” concluded Valliappan Muthu, MD, and colleagues. However, “the ideal duration and optimal dose of LAMB for nebulization are unclear.”
Study details
“Nebulized amphotericin B for preventing exacerbations in allergic bronchopulmonary aspergillosis: A systematic review and meta-analysis” was published online in Pulmonary Pharmacology and Therapeutics.
Limitations
The current review is limited by the small number of included trials and may have a high risk of bias. Therefore, more evidence is required for the use of nebulized amphotericin B in routine care. The authors have disclosed no conflicts of interest.

Palliative Care: Utilization Patterns in Inpatient Dermatology
Palliative care (PC) is a field of medicine that focuses on improving quality of life by managing physical symptoms as well as mental and spiritual well-being in patients with severe illnesses.1,2 Despite cases of severe dermatologic disease, the use of PC in the field of dermatology is limited, often leaving patients with a range of unmet needs.2,3 In one study that explored PC in patients with melanoma, only one-third of patients with advanced melanoma had a PC consultation.4 Reasons behind the lack of utilization of PC in dermatology include time constraints and limited training in addressing the complex psychosocial needs of patients with severe dermatologic illnesses.1 We conducted a retrospective, cross-sectional, single-institution study of specific inpatient dermatology consultations over a 5-year period to describe PC utilization among patients who were hospitalized with select severe dermatologic diseases.
Methods
A retrospective, cross-sectional study of inpatient dermatology consultations over a 5-year period (October 2016 to October 2021) was performed at Atrium Health Wake Forest Baptist Medical Center (Winston-Salem, North Carolina). Patients’ medical records were reviewed if they had one of the following diseases: bullous pemphigoid, calciphylaxis, cutaneous T-cell lymphoma (CTCL), drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, erythrodermic psoriasis, graft-vs-host disease, pemphigus vulgaris (PV), purpura fulminans, pyoderma gangrenosum, and Stevens-Johnson syndrome/toxic epidermal necrolysis. These diseases were selected for inclusion because they have been associated with a documented increase in inpatient mortality and have been described in the published literature on PC in dermatology.2 This study was reviewed and approved by the Wake Forest University institutional review board.
Use of PC consultative services along with other associated consultative care (ie, recreation therapy [RT], acute pain management, pastoral care) was assessed for each patient. Recreation therapy included specific interventions such as music therapy, arts/craft therapy, pet therapy, and other services with the goal of improving patient cognitive, emotional, and social function. For patients with a completed PC consultation, goals for PC intervention were recorded.
Results
The total study sample included 193 inpatient dermatology consultations. The mean age of the patients was 58.9 years (range, 2–100 years); 66.8% (129/193) were White and 28.5% (55/193) were Black (Table). Palliative care was consulted in 5.7% of cases, with consultations being requested by the primary care team. Reasons for PC consultation included assessment of the patient’s goals of care (4.1% [8/193]), pain management (3.6% [7/193]), non–pain symptom management (2.6% [5/193]), psychosocial support (1.6% [3/193]), and transitions of care (1.0% [2/193]). The average length of patients’ hospital stay prior to PC consultation was 11.5 days(range, 1–32 days). Acute pain management was the reason for consultation in 15.0% of cases (29/193), RT in 21.8% (42/193), and pastoral care in 13.5% (26/193) of cases. Patients with calciphylaxis received the most PC and pain consultations, but fewer than half received these services. Patients with calciphylaxis, PV, purpura fulminans, and CTCL received a higher percentage of PC consultations than the overall cohort, while patients with calciphylaxis, DRESS syndrome, PV, and pyoderma gangrenosum received relatively more pain consultations than the overall cohort (Figure).
Comment
Clinical practice guidelines for quality PC stress the importance of specialists being familiar with these services and the ability to involve PC as part of the treatment plan to achieve better care for patients with serious illnesses.5 Our results demonstrated low rates of PC consultation services for dermatology patients, which supports the existing literature and suggests that PC may be highly underutilized in inpatient settings for patients with serious skin diseases. Use of PC was infrequent and was initiated relatively late in the course of hospital admission, which can negatively impact a patient’s well-being and care experience and can increase the care burden on their caregivers and families.2
Our results suggest a discrepancy in the frequency of formal PC and other palliative consultative services used for dermatologic diseases, with non-PC services including RT, acute pain management, and pastoral care more likely to be utilized. Impacting this finding may be that RT, pastoral care, and acute pain management are provided by nonphysician providers at our institution, not attending faculty staffing PC services. Patients with calciphylaxis were more likely to have PC consultations, potentially due to medicine providers’ familiarity with its morbidity and mortality, as it is commonly associated with end-stage renal disease. Similarly, internal medicine providers may be more familiar with pain classically associated with PG and PV and may be more likely to engage pain experts. Some diseases with notable morbidity and potential mortality were underrepresented including SJS/TEN, erythrodermic psoriasis, CTCL, and GVHD.
Limitations of our study included examination of data from a single institution, as well as the small sample sizes in specific subgroups, which prevented us from making comparisons between diseases. The cross-sectional design also limited our ability to control for confounding variables.
Conclusion
We urge dermatology consultation services to advocate for patients with serious skin diseases andinclude PC consultation as part of their recommendations to primary care teams. Further research should characterize the specific needs of patients that may be addressed by PC services and explore ways dermatologists and others can identify and provide specialty care to hospitalized patients.

Practice Points
- Although severe dermatologic disease negatively impacts patients’ quality of life, palliative care may be underutilized in this population.
- Palliative care should be an integral part of caring for patients who are admitted to the hospital with serious dermatologic illnesses.
Placebo effect can be found in a cup of coffee
The best part of waking up is placebo in your cup
Coffee makes the world go round. It’s impossible to picture any workplace without a cast of forlorn characters huddled around the office coffee maker on a Monday morning, imbibing their beverage du jour until they’ve been lifted out of their semi-zombified stupor.
Millions upon millions of people swear by their morning coffee. And if they don’t get that sweet, sweet caffeine boost, they’ll make Garfield and the Boomtown Rats’ opinions of Mondays look tame. And it only makes sense that they’d believe that. After all, caffeine is a stimulant. It helps your brain focus and kicks it into overdrive. Of course drinking a beverage full of caffeine wakes you up. Right?
Not so fast, a group of Portuguese researchers say. That morning cup of coffee? It may actually be a placebo. Cue the dramatic sound effect.
Here’s the scoop: After recruiting a group of coffee drinkers (at least one cup a day), the researchers kept their test subjects off of coffee for at least 3 hours, then performed a brief functional MRI scan on all test subjects. Half an hour later, study participants received either a standard cup of coffee or pure caffeine. Half an hour after consuming their respective study product, the subjects underwent a second MRI.
As expected, both people who consumed coffee and those who consumed pure caffeine showed decreased connectivity in the default mode network after consumption, indicating preparation in the brain to move from resting to working on tasks. However, those who had pure caffeine did not show increased connectivity in the visual and executive control networks, while those who had coffee did. Simply put, caffeine may wake you up, but it doesn’t make you any sharper. Only coffee gets you in shape for that oh-so-important Monday meeting.
This doesn’t make a lot of sense. How can the drug part of coffee not be responsible for every effect the drink gives you? That’s where the placebo comes in, according to the scientists. It’s possible the effect they saw was caused by withdrawal – after just 3 hours? Yikes, hope not – but it’s more likely it comes down to psychology. We expect coffee to wake us up and make us ready for the day, so that’s exactly what it does. Hey, if that’s all it takes, time to convince ourselves that eating an entire pizza is actually an incredibly effective weight loss tool. Don’t let us down now, placebo effect.
Bread, milk, toilet paper, AFib diagnosis
Now consider the shopping cart. It does its job of carrying stuff around the store well enough, but can it lift you out of a semi-zombified stupor in the morning? No. Can it identify undiagnosed atrial fibrillation? Again, no.
Not so fast, say the investigators conducting the SHOPS-AF (Supermarket/Hypermarket Opportunistic Screening for Atrial Fibrillation) study. They built a better shopping cart. Except they call it a trolley, not a cart, since the study was conducted in England, where they sometimes have funny names for things.
Their improved shopping trolley – we’re just going to call it a cart from here on – has an electrocardiogram sensor embedded into the handlebar, so it can effectively detect AFib in shoppers who held it for at least 60 seconds. The sensor lights up red if it detects an irregular heartbeat and green if it does not. Let’s see a cup of coffee do that.
They put 10 of these modified carts in four supermarkets in Liverpool to see what would happen. Would shoppers be able to tell that we secretly replaced the fine coffee they usually serve with Folger’s crystals? Oops. Sorry about that. Coffee on the brain, apparently. Back to the carts.
A total of 2,155 adult shoppers used one of the carts over 2 months, and electrocardiogram data were available for 220 participants who either had a red light on the sensor and/or an irregular pulse that suggested atrial fibrillation. After further review by the SHOPS-AF cardiologist, AFib was diagnosed in 59 shoppers, of whom 39 were previously undiagnosed.
They’re already working to cut the scan time to 30 seconds for SHOPS-AF II, but we’re wondering about a possible flaw in the whole health-care-delivery-through-shopping-cart scenario. When we go to the local super/hyper/megamart, it seems like half of the people trundling up and down the aisles are store employees filling orders for customers who won’t even set foot inside. Is the shopping cart on its way out? Maybe. Who wants to tell the SHOPS-AF II team? Not us.
Put pneumonia where your mouth is
Getting dentures does not mean the end of dental care. If anything, new research reveals a huge reason for staying on top of one’s denture care: pneumonia.
It all started with swabs. Scientists in the United Kingdom took mouth, tongue, and denture specimens from frail elderly hospital patients who had pneumonia and wore dentures and from similar patients in care homes who wore dentures and did not have pneumonia. When they compared the microbial populations of the two groups, the investigators found about 20 times the number of respiratory pathogens on the dentures of those with pneumonia.
The research team suggested that dentures may play a role in causing pneumonia, but lead author Josh Twigg, BDS, PhD, also noted that “you certainly couldn’t say that people got pneumonia because they were wearing dentures. It’s just showing that there is an association there.” Improper cleaning, though, could lead to microbial colonization of the dentures, and patients could be inhaling those microbes into their lungs, thereby turning a dental issue into a respiratory issue.
More research needs to be done on the association between dentures and pneumonia, but Dr. Twigg hoped that the results of this study could be presented to the public. The message? “It is important to clean dentures thoroughly” and visit the dentist regularly, he said, but the best way to prevent denture-related infections is to avoid needing to wear dentures entirely.

Comorbid respiratory disease key predictor of NTM-PD
(NTM-PD), data from a systematic review of 99 studies indicate.
NTM-PD is frequently underdiagnosed, and data on specific risk factors are lacking, especially for high-risk individuals with preexisting respiratory diseases, wrote Michael R. Loebinger, PhD, of Imperial College London, and colleagues.
“NTM-PD can be a substantial burden for patients, contributing to lung function decline and reduced health-related quality of life, and is associated with significant morbidity and mortality,” they said.
In a study published in the journal Chest, the researchers identified 99 studies published between 2011 and 2021. Of these, 24 reported an association between risk factors and NTM-PD among patients with respiratory disease compared with patients without NTM-PD and with healthy control persons without NTM-PD; these studies were included in the meta-analysis.
Overall, comorbid respiratory disease was significantly associated with an increased risk of NTM-PD, with odds ratios ranging from 4.15 for asthma to 21.43 for bronchiectasis. Other conditions significantly associated with NTM-PD risk included history of tuberculosis (odds ratio, 12.69), interstitial lung disease (OR, 6.39), and chronic obstructive pulmonary disease (COPD) (OR, 6.63).
Other factors associated with increased NTM-PD risk included inhaled corticosteroids (OR, 4.46), oral corticosteroids (OR, 3.37), and other immunosuppressants (OR, 2.60). Additional risk factors were use of anti–tumor necrosis factor-alpha for rheumatoid arthritis (OR, 2.13), solid tumors (OR, 4.66), current pneumonia (OR, 5.54), cardiovascular disease (OR, 1.73), and low body mass index (OR, 3.04).
Additional marginal or nonsignificant associations with NTM-PD risk were found for lung function, diabetes, renal disease, cancer, healthy weight, and infection with either Pseudomonas aeruginosa or Staphylococcus aureus.
Possible protective factors, though not significant, included increasing or high BMI and long-term macrolide use.
Bronchiectasis, which is associated with the highest risk of NTM-PD, was assessed in four studies. It was evaluated less frequently because it was often considered a reason for study exclusion, the researchers wrote in their discussion.
“However, many studies report high numbers of patients with nodular bronchiectatic NTM-PD and is suggested to be almost universal in patients with noncavitary NTM-PD,” they said.
The most common risk factors for NTM-PD in the included studies were the use of immunosuppressants, female sex, COPD comorbidity, and history of suspected tuberculosis.
The findings were limited by several factors, including the high level of heterogeneity among the included studies, the lack of data on attributable risk, and inconsistent definitions of NTM-PD, the researchers noted. However, the results may be useful for highlighting risk factors that could be used to identify high-risk patients and to promote early diagnosis and treatment, they said. In addition, long-term studies are needed regarding the impact of multiple potential risk factors on individual risk for NTM-PD among patients with respiratory disease, they concluded.
The study was supported by Insmed BV. Dr. Loebinger has relationships with Insmed, AstraZeneca, Chiesi, Savara, Parion, Zambon, 30T, Electromed, Recode, AN2 Therapeutics, and Armata.

CDC signs off on RSV vaccine for older adults
The Centers for Disease Control and Prevention has given a green light to two new vaccines to protect against respiratory syncytial virus, or RSV, in older adults.
CDC Director Rochelle P. Walensky, MD, MPH, agreed with and endorsed the recommendations made earlier by CDC advisors that people age 60 and over may get one of two new vaccines for RSV. Decisions should be made based on discussions with one’s health care provider about whether the vaccine is right for them, the federal health agency said.
The new vaccines, the first licensed in the United States to protect against the respiratory illness, are expected to be available this fall.
On June 21, the CDC’s Advisory Committee on Immunization Practices (ACIP), an independent panel, stopped short of recommending the vaccines for everyone age 65 and above, which was the original question the committee was to consider. The experts amended that question, changing it to whether the panel should recommend the vaccine for those 65 and above if the person and their doctor agreed. The committee voted 9 to 5 in favor.
RSV vaccines
RSV leads to 6,000 to 10,000 deaths a year in the United States among those age 65 and older and 60,000 to 160,000 hospitalizations in that group. Seniors and infants are among the most vulnerable to the lower respiratory infection, marked by runny nose, wheezing, sneezing, decreased appetite, and fever.
The FDA in May approved two vaccines — GSK’s Arexvy and Pfizer’s Abrysvo — for adults age 60 and above.
The vote recommending shared decision-making about the vaccine, instead of a routine vaccination recommended for all, “is a weaker recommendation,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center in Nashville and medical director of the National Foundation for Infectious Diseases. Dr. Schaffner is a non-voting member of ACIP. He attended the meeting.
He said the experts voiced concern about a number of issues, including what some saw as a lack of sufficient data from trials on the most vulnerable groups, such as nursing home residents.
Experts also wanted more information about the duration of protection and exactly when a second dose might be needed. At the meeting, a GSK official said its vaccine was 84.6% effective after one and a half seasons, down from 94.1% after one season. A Pfizer official said its vaccine decreased the risk of RSV with three or more symptoms by 78.6% after a season and a half, down from 88.9% after one season.
The panel also wanted more data on whether the RSV vaccines could be administered at the same time as other vaccines recommended for adults.
Both companies gave a range of cost estimates. Pfizer expects its vaccine to cost $180 to $270 but said it could not guarantee that range. GSK said it expects a price of $200 to $295. Under the Inflation Reduction Act, recommended vaccines are covered under Medicare for those with Part D plans, which 51 million of 65 million Medicare patients have. Commercial insurance is likely to cover the vaccines if the CDC recommends them.

RSV leads to 6,000 to 10,000 deaths a year in the United States among those age 65 and older and 60,000 to 160,000 hospitalizations in that group. Seniors and infants are among the most vulnerable to the lower respiratory infection, marked by runny nose, wheezing, sneezing, decreased appetite, and fever.
The FDA in May approved two vaccines — GSK’s Arexvy and Pfizer’s Abrysvo — for adults age 60 and above.
The vote recommending shared decision-making about the vaccine, instead of a routine vaccination recommended for all, “is a weaker recommendation,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center in Nashville and medical director of the National Foundation for Infectious Diseases. Dr. Schaffner is a non-voting member of ACIP. He attended the meeting.
He said the experts voiced concern about a number of issues, including what some saw as a lack of sufficient data from trials on the most vulnerable groups, such as nursing home residents.
Experts also wanted more information about the duration of protection and exactly when a second dose might be needed. At the meeting, a GSK official said its vaccine was 84.6% effective after one and a half seasons, down from 94.1% after one season. A Pfizer official said its vaccine decreased the risk of RSV with three or more symptoms by 78.6% after a season and a half, down from 88.9% after one season.
The panel also wanted more data on whether the RSV vaccines could be administered at the same time as other vaccines recommended for adults.
Both companies gave a range of cost estimates. Pfizer expects its vaccine to cost $180 to $270 but said it could not guarantee that range. GSK said it expects a price of $200 to $295. Under the Inflation Reduction Act, recommended vaccines are covered under Medicare for those with Part D plans, which 51 million of 65 million Medicare patients have. Commercial insurance is likely to cover the vaccines if the CDC recommends them.

The Centers for Disease Control and Prevention has given a green light to two new vaccines to protect against respiratory syncytial virus, or RSV, in older adults.
CDC Director Rochelle P. Walensky, MD, MPH, agreed with and endorsed the recommendations made earlier by CDC advisors that people age 60 and over may get one of two new vaccines for RSV. Decisions should be made based on discussions with one’s health care provider about whether the vaccine is right for them, the federal health agency said.
The new vaccines, the first licensed in the United States to protect against the respiratory illness, are expected to be available this fall.
On June 21, the CDC’s Advisory Committee on Immunization Practices (ACIP), an independent panel, stopped short of recommending the vaccines for everyone age 65 and above, which was the original question the committee was to consider. The experts amended that question, changing it to whether the panel should recommend the vaccine for those 65 and above if the person and their doctor agreed. The committee voted 9 to 5 in favor.

Severe strep infections rebound after pandemic lull
Severe infections caused by group A streptococcus bacteria are on the rise in countries around the world, including the United States, according to new data from the Centers for Disease Control and Prevention.
Group A strep bacteria usually cause mild illnesses like strep throat and scarlet fever. But they can also cause more severe diseases, like the flesh-eating disease necrotizing fasciitis and streptococcal toxic shock syndrome, known as invasive group A strep infections.
These infections fell by 25% during the COVID-19 pandemic and were especially low in children. The number of milder infections also dropped. But in 2022, severe infections came roaring back, particularly in children.
such as Colorado and Minnesota.
Now in 2023, invasive infections are high in children in some parts of the country, even after respiratory viruses like the flu and respiratory syncytial virus (RSV) decreased in those areas. Some parts of the country also saw high rates of invasive infections in older adults.
Less severe strep A infections in children have returned to levels similar to or higher than those seen in prepandemic years.
A similar postpandemic resurgence in invasive infections has also been seen in other countries, including Canada, the United Kingdom, France, and Denmark.
Strep A is a very common bacteria that causes only mild or no symptoms in most people, and severe infections are usually quite rare. They tend to affect the most vulnerable people: those who have another virus, multiple chronic conditions, or an open wound.
People should watch for fever, headaches, or confusion during a strep infection, which all might signal a more severe illness.

FDA passes on olorofim despite critical need for antifungals
The U.S. Food and Drug Administration is declining to approve the investigational antifungal olorofim and is asking for more data, according to a news release from the manufacturer, F2G.
Olorofim, (formerly known as F901318) is the first in the orotomide class of antifungals to be evaluated clinically for the treatment of invasive mold infections. Its maker, F2G, is a biotech company based in Manchester, England, that focuses on developing drugs for rare fungal diseases.
The company says it remains optimistic and will address the FDA’s requirements and continue to seek approval.
The FDA’s denial comes as fungal infections are becoming increasingly common and resistant to treatment. There are only four antifungal classes currently available, and there are few new candidates in the pipeline. No new classes of antifungals have been developed in 2 decades.
David Andes, MD, chief of the division of infectious diseases at the University of Wisconsin–Madison, told this news organization he shares the hope that the company can meet the requirements to gain approval.
“Some of the early results were really exciting,” he said. “People are enthusiastic about the compound because it has a novel mechanism of action, and it is active against a group of fungi that we have limited to no options for.”
Early results ‘exciting’
Dr. Andes said several physicians have been able to prescribe olorofim under the compassionate use program “and have witnessed success.”
Olorofim is the first antifungal agent to be granted breakthrough therapy designation, which the FDA granted in November 2019 for the treatment of invasive mold infections for patients with limited or no treatment options, including patients with refractory aspergillosis or those who are intolerant of currently available therapy. It is also indicated for infections due to Lomentospora prolificans, Scedosporium, and Scopulariopsis species.
Olorofim received a second breakthrough therapy designation in October 2020. The second designation was granted for treatment of central nervous system coccidioidomycosis that is refractory or for cases that cannot be treated with standard-of-care therapy.
It is very difficult for patients to be approved to receive compassionate use medicines, Dr. Andes pointed out. “I’d like to have access sooner rather than later,” he added.
Dr. Andes says the drugs are expensive and are time consuming to produce. And with antifungals, it is difficult to demonstrate safety in comparison with other antimicrobial agents because “it’s hard to hurt a fungus without having toxicity with human cells.”
Complete response letter issued
F2G received a complete response letter from the FDA regarding its new drug application for olorofim, according to the news release issued by the company. “While F2G is disappointed with this outcome, we remain optimistic about olorofim’s potential to address an unmet need for patients with invasive fungal infections who have exhausted their treatment alternatives,” Francesco Maria Lavino, chief executive officer, said in the release. “We are assessing the details of the Complete Response Letter, and we plan to meet with the FDA to discuss it further.”
Dr. Andes says few other antifungals have made it as far as olorofim in clinical trials.
Lance B. Price, PhD, codirector of the Antibiotic Resistance Action Center at George Washington University in Washington, told this news organization that despite the lack of antifungals in the pipeline, “We can’t allow our desperation to override the checkpoints that ensure that antifungals are safe to use in people.”
In the meantime, he said, it is important to preserve the utility of current antifungals by avoiding overusing them in medicine and agriculture.
“Sadly,” he said, “a drug called ipflufenoquin, which works by a similar mode of action as olorofim, has already been approved by the U.S. Environmental Protection Agency for use in plant agriculture. This could weaken the effectiveness of olorofim for treating things like Aspergillus infections even before the drug has been approved for use in humans.”
Plant drug undermining olorofim efficacy in humans
“While I’m sure this makes financial sense for the makers of ipflufenoquin, it borders on insanity from a public health perspective,” Dr. Price said.
Meanwhile, the global threat of fungal infections grows. The World Health Organization has launched its first-ever list of health-threatening fungi. Authors of a WHO report that contains the list write, “The invasive forms of these fungal infections often affect severely ill patients and those with significant underlying immune system–related conditions.”
F2G will continue to expand olorofim’s clinical trial program, according to the company’s statement. Along with its partner, Shionogi, it is enrolling patients with proven or probable invasive aspergillosis in a global phase 3 trial (OASIS), which will compare outcomes after treatment with olorofim in comparison with amphotericin B liposome (AmBisome) followed by standard of care.

Low-calorie tastes sweeter with a little salt
Low-calorie tastes sweeter with a little salt
Diet and sugar-free foods and drinks seem like a good idea, but it’s hard to get past that strange aftertaste, right? It’s the calling card for the noncaloric aspartame- and stevia-containing sweeteners that we consume to make us feel like we can have the best of both worlds.
That weird lingering taste can be a total turn-off for some (raises hand), but researchers have found an almost facepalm solution to the not-so-sweet problem, and it’s salt.
Now, the concept of sweet and salty is not a far-fetched partnership when it comes to snack consumption (try M&Ms in your popcorn). The researchers at Almendra, a manufacturer of stevia sweeteners, put that iconic flavor pair to the test by adding mineral salts that have some nutritional value to lessen the effect of a stevia compound, rebaudioside A, found in noncaloric sweeteners.
The researchers added in magnesium chloride, calcium chloride, and potassium chloride separately to lessen rebaudioside A’s intensity, but they needed so much salt that it killed the sweet taste completely. A blend of the three mineral salts, however, reduced the lingering taste by 79% and improved the real sugar-like taste. The researchers tried this blend in reduced-calorie orange juice and a citrus-flavored soft drink, improving the taste in both.
The salty and sweet match comes in for the win once again. This time helping against the fight of obesity instead of making it worse.
Pseudomonas’ Achilles’ heel is more of an Achilles’ genetic switch
Today, on the long-awaited return of “Bacteria vs. the World,” we meet one of the rock stars of infectious disease.
LOTME: Through the use of imaginary technology, we’re talking to Pseudomonas aeruginosa. Thanks for joining us on such short notice, after Neisseria gonorrhoeae canceled at the last minute.
P. aeruginosa: No problem. I think we can all guess what that little devil is up to.
LOTME: Bacterial resistance to antibiotics is a huge problem for our species. What makes you so hard to fight?
P. aeruginosa: We’ve been trying to keep that a secret, actually, but now that researchers in Switzerland and Denmark seem to have figured it out, I guess it’s okay for me to spill the beans.
LOTME: Beans? What do beans have to do with it?
P. aeruginosa: Nothing, it’s just a colloquial expression that means I’m sharing previously private information.
LOTME: Sure, we knew that. Please, continue your spilling.
P. aeruginosa: The secret is … Well, let’s just say we were a little worried when the Clash released “Should I Stay or Should I Go” back in the 1980s.
LOTME: The Clash? Now we’re really confused.
P. aeruginosa: The answer to their question, “Should I stay or should I go? is yes. Successful invasion of a human is all about division of labor. “While one fraction of the bacterial population adheres to the mucosal surface and forms a biofilm, the other subpopulation spreads to distant tissue sites,” is how the investigators described it. We can increase surface colonization by using a “job-sharing” process, they said, and even resist antibiotics because most of us remain in the protective biofilm.
LOTME: And they say you guys don’t have brains.
P. aeruginosa: But wait, there’s more. We don’t just divide the labor randomly. After the initial colonization we form two functionally distinct subpopulations. One has high levels of the bacterial signaling molecule c-di-GMP and stays put to work on the biofilm. The other group, with low levels of c-di-GMP, heads out to the surrounding tissue to continue the colonization. As project leader Urs Jenal put it, “By identifying the genetic switch, we have tracked down the Achilles heel of the pathogen.”
LOTME: Pretty clever stuff, for humans, anyway.
P. aeruginosa: We agree, but now that you know our secret, we can’t let you share it.
LOTME: Wait! The journal article’s already been published. Your secret is out. You can’t stop that by infecting me.
P. aeruginosa: True enough, but are you familiar with the fable of the scorpion and the frog? It’s our nature.
LOTME: Nooooo! N. gonorrhoeae wouldn’t have done this!
What a pain in the Butt
Businesses rise and businesses fall. We all know that one cursed location, that spot in town where we see businesses move in and close up in a matter of months. At the same time, though, there are also businesses that have been around as long as anyone can remember, pillars of the community.
Corydon, IN., likely has a few such long-lived shops, but it is officially down one 70-year-old family business as of late April, with the unfortunate passing of beloved local pharmacy Butt Drugs. Prescription pick-up in rear.
The business dates back to 1952, when it was founded as William H. Butt Drugs. We’re sure William Butt was never teased about his last name. Nope. No one would ever do that. After he passed the store to his children, it underwent a stint as Butt Rexall Drugs. When the shop was passed down to its third-generation and ultimately final owner, Katie Butt Beckort, she decided to simplify the name. Get right down to the bottom of things, as it were.
Butt Drugs was a popular spot, featuring an old-school soda fountain and themed souvenirs. According to Ms. Butt Beckort, people would come from miles away to buy “I love Butt Drugs” T-shirts, magnets, and so on. Yes, they knew perfectly well what they were sitting on.
So, if was such a hit, why did it close? Butt Drugs may have a hilarious name and merchandise to match, but the pharmacy portion of the pharmacy had been losing money for years. You know, the actual point of the business. As with so many things, we can blame it on the insurance companies. More than half the drugs that passed through Butt Drugs’ doors were sold at a loss, because the insurance companies refused to reimburse the store more than the wholesale price of the drug. Not even a good butt drug could clear up that financial diarrhea.
And so, we’ve lost Butt Drugs forever. Spicy food enthusiasts, coffee drinkers, and all patrons of Taco Bell, take a moment to reflect and mourn on what you’ve lost. No more Butt Drugs to relieve your suffering. A true kick in the butt indeed.

Businesses rise and businesses fall. We all know that one cursed location, that spot in town where we see businesses move in and close up in a matter of months. At the same time, though, there are also businesses that have been around as long as anyone can remember, pillars of the community.
Corydon, IN., likely has a few such long-lived shops, but it is officially down one 70-year-old family business as of late April, with the unfortunate passing of beloved local pharmacy Butt Drugs. Prescription pick-up in rear.
The business dates back to 1952, when it was founded as William H. Butt Drugs. We’re sure William Butt was never teased about his last name. Nope. No one would ever do that. After he passed the store to his children, it underwent a stint as Butt Rexall Drugs. When the shop was passed down to its third-generation and ultimately final owner, Katie Butt Beckort, she decided to simplify the name. Get right down to the bottom of things, as it were.
Butt Drugs was a popular spot, featuring an old-school soda fountain and themed souvenirs. According to Ms. Butt Beckort, people would come from miles away to buy “I love Butt Drugs” T-shirts, magnets, and so on. Yes, they knew perfectly well what they were sitting on.
So, if was such a hit, why did it close? Butt Drugs may have a hilarious name and merchandise to match, but the pharmacy portion of the pharmacy had been losing money for years. You know, the actual point of the business. As with so many things, we can blame it on the insurance companies. More than half the drugs that passed through Butt Drugs’ doors were sold at a loss, because the insurance companies refused to reimburse the store more than the wholesale price of the drug. Not even a good butt drug could clear up that financial diarrhea.
And so, we’ve lost Butt Drugs forever. Spicy food enthusiasts, coffee drinkers, and all patrons of Taco Bell, take a moment to reflect and mourn on what you’ve lost. No more Butt Drugs to relieve your suffering. A true kick in the butt indeed.
Low-calorie tastes sweeter with a little salt
Diet and sugar-free foods and drinks seem like a good idea, but it’s hard to get past that strange aftertaste, right? It’s the calling card for the noncaloric aspartame- and stevia-containing sweeteners that we consume to make us feel like we can have the best of both worlds.
That weird lingering taste can be a total turn-off for some (raises hand), but researchers have found an almost facepalm solution to the not-so-sweet problem, and it’s salt.
Now, the concept of sweet and salty is not a far-fetched partnership when it comes to snack consumption (try M&Ms in your popcorn). The researchers at Almendra, a manufacturer of stevia sweeteners, put that iconic flavor pair to the test by adding mineral salts that have some nutritional value to lessen the effect of a stevia compound, rebaudioside A, found in noncaloric sweeteners.
The researchers added in magnesium chloride, calcium chloride, and potassium chloride separately to lessen rebaudioside A’s intensity, but they needed so much salt that it killed the sweet taste completely. A blend of the three mineral salts, however, reduced the lingering taste by 79% and improved the real sugar-like taste. The researchers tried this blend in reduced-calorie orange juice and a citrus-flavored soft drink, improving the taste in both.
The salty and sweet match comes in for the win once again. This time helping against the fight of obesity instead of making it worse.
Pseudomonas’ Achilles’ heel is more of an Achilles’ genetic switch
Today, on the long-awaited return of “Bacteria vs. the World,” we meet one of the rock stars of infectious disease.
LOTME: Through the use of imaginary technology, we’re talking to Pseudomonas aeruginosa. Thanks for joining us on such short notice, after Neisseria gonorrhoeae canceled at the last minute.
P. aeruginosa: No problem. I think we can all guess what that little devil is up to.
LOTME: Bacterial resistance to antibiotics is a huge problem for our species. What makes you so hard to fight?
P. aeruginosa: We’ve been trying to keep that a secret, actually, but now that researchers in Switzerland and Denmark seem to have figured it out, I guess it’s okay for me to spill the beans.
LOTME: Beans? What do beans have to do with it?
P. aeruginosa: Nothing, it’s just a colloquial expression that means I’m sharing previously private information.
LOTME: Sure, we knew that. Please, continue your spilling.
P. aeruginosa: The secret is … Well, let’s just say we were a little worried when the Clash released “Should I Stay or Should I Go” back in the 1980s.
LOTME: The Clash? Now we’re really confused.
P. aeruginosa: The answer to their question, “Should I stay or should I go? is yes. Successful invasion of a human is all about division of labor. “While one fraction of the bacterial population adheres to the mucosal surface and forms a biofilm, the other subpopulation spreads to distant tissue sites,” is how the investigators described it. We can increase surface colonization by using a “job-sharing” process, they said, and even resist antibiotics because most of us remain in the protective biofilm.
LOTME: And they say you guys don’t have brains.
P. aeruginosa: But wait, there’s more. We don’t just divide the labor randomly. After the initial colonization we form two functionally distinct subpopulations. One has high levels of the bacterial signaling molecule c-di-GMP and stays put to work on the biofilm. The other group, with low levels of c-di-GMP, heads out to the surrounding tissue to continue the colonization. As project leader Urs Jenal put it, “By identifying the genetic switch, we have tracked down the Achilles heel of the pathogen.”
LOTME: Pretty clever stuff, for humans, anyway.
P. aeruginosa: We agree, but now that you know our secret, we can’t let you share it.
LOTME: Wait! The journal article’s already been published. Your secret is out. You can’t stop that by infecting me.
P. aeruginosa: True enough, but are you familiar with the fable of the scorpion and the frog? It’s our nature.
LOTME: Nooooo! N. gonorrhoeae wouldn’t have done this!
