75% of women are affected by Candida albicans, the cause of vulvovaginal candidiasis. Valentine et al. address the interactions between Candida, vaginal microbiome, and host factors to better understand infections and the development of novel treatment strategies.

Towards shorter therapy for candidaemia: defining uncomplicated candidaemia in adults

@ilanareinhold.bsky.social ... @olivercornely.bsky.social

Thoughtful approach to selecting patients for whom shorter candidemia therapy MAY be safe

www.thelancet.com/journals/lan...
Clinical and microbiological criteria evaluated to distinguish uncomplicated from complicated candidaemia Figure 2 Time-dependent criteria proposed to distinguish uncomplicated from complicated candidaemia
Timeline depicting the onset of candidaemia (upper blue rectangle), timing of antifungal treatment initiation (upper grey rectangle), and time-dependent criteria. Day 0 refers to initiation of antifungal treatment. Criteria proposed to enter definition of complicated candidaemia are: neutropenia for over 10 days in the past 30 days, ongoing use of glucocorticosteroids for 21 days or more, missing removal of central venous line for over 48 h, missing source control of intra-abdominal candidiasis for over 5 days, and duration of candidaemia for 120 h or more. Panel: Definition criteria for uncomplicated candidaemia after 5 days of treatment
Absence of relevant immunosuppression
• No neutropenia (<500 cells per μl) for more than 10 days in the last 30 days
• No recent or newly initiated ongoing use of glucocorticosteroids (≥0·3 mg/kg per day for ≥3 weeks)
• No haematological malignancy without remission
• No allogeneic haematopoietic stem-cell transplantation
• No acute graft-versus-host disease grade III or IV
Absence of active illicit intravenous drug use
Controlled source
• Central venous line, if any, is removed within 24–48 h after diagnosis of candidaemia
• No implantable cardiac electronic device, ventricular assist device, extracorporeal membrane oxygenation, or indwelling intravascular foreign body that cannot be removed present at onset of candidaemia
• Intra-abdominal candidiasis (eg, abdominal abscess or peritonitis) is surgically or interventionally controlled
Absence of extra-abdominal deep-seated candidiasis
• No central nervous system infection, chorioretinitis, endophthalmitis, intravascular infection, endocarditis, renal abscess, osteomyelitis, or joint infection
Clinical response
• No attributable signs or symptoms for persistent candidaemia 120 h or more after treatment initiation
• No signs, symptoms, or indicative imaging for deep- seated candidiasis 120 h or more after treatment initiation
Mycological response
• Candidaemia less than 120 h between blood draws of the index blood culture and the first negative blood culture
Antifungal susceptibility testing available
• Absence of echinocandin-resistant Candida species

The koji-fungus, Aspergillus oryzae, traditionally used in Japanese brewing, is now widely used to make enzymes.

It seems its capacity for enzyme production is thanks to its unique ability to proportionally increase cell volume and nuclear number.

This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵

Federal funding to universities is appropriated by Congress. Trump asks them to sign an "agreement" to get preference for future funding. This is exerting control over higher ed.

History rhymes. University professors in Italy were subjected to this in 1931 by Mussolini.

The data and evidence are clear. Over the past 8 months, the egregious actions of President Trump and his enablers have caused real harm to people and communities across the country.

This administration's first 6 months have been characterized by destruction, division, and chaos.

I wrote something about my impression of RFK Jr.’s announcement regarding the “causes” of autism last week.

As usual, it’s a magician’s trick; a misdirection borne of his inability to actually find anything new or useful for families of autistic kids.
