Reputation is multidimensional, with some traits being more relevant than others in particular contexts. Can people selectively respond to reputational cues relevant to the task at hand? Across three studies, we examined how people weigh cues about helpfulness and competence when forming expectations about strangers' behavior. Using adapted investment games, we varied whether a stranger's helpfulness or competence predicted participants' future payoffs.

Background: Exposure to fungi, especially Aspergillus fumigatus, can elicit potent allergic inflammation that triggers and worsens asthmatic disease. Dendritic cells (DCs) initiate allergic inflammatory responses to allergic stimuli. However, it is unclear if Af spores during isotropic growth (early spore swelling) can activate DCs to initiate allergic responses or if germination is required.

Objective: To evaluate adherence to treatment guideline recommendations across the continuum of prostate cancer (PCa) care by US community urologists using several PCa-specific performance indicators (PIs). Additionally, to determine which practice-related factors, such as having a designated PCa patient champion, active patient management in a patient portal, and in-office dispensing of medications, were associated with improved PI performance.

Methods: Electronic medical record data were collected retrospectively from the PPS Analytics Patient Population Health Management Platform.

Fungi play critical roles in the homeostasis of ecosystems globally and have emerged as significant causes of an expanding repertoire of devastating diseases in plants, animals, and humans. In this Commentary, we highlight the importance of fungal pathogens and argue for concerted research efforts to enhance understanding of fungal virulence, antifungal immunity, novel drug targets, antifungal resistance, and the mycobiota to improve human health.

Article Synopsis
  • Neutrophil activation needs careful control to prevent diseases, as uncontrolled neutrophil extracellular traps (NETs) can cause more harm than good.
  • A receptor called MICL helps keep this process in check by recognizing DNA in NETs, and when it doesn't work properly, it can lead to too many NETs being formed.
  • In diseases like rheumatoid arthritis and lupus, there are autoantibodies that block MICL, which worsens the disease, but during certain infections, like with a fungus, having more NETs can actually help fight off the infection.

Purpose: Approximately 25% to 50% of patients with high-risk localized prostate cancer experience biochemical recurrence (BCR) within 2 years of radical prostatectomy. The Apa-RP study (NCT04523207) investigated whether adjuvant apalutamide plus androgen deprivation therapy (ADT) in high-risk patients who have undergone radical prostatectomy improved BCR-free survival.

Materials And Methods: Apa-RP was a multicenter, open-label, single-arm, phase 2 study conducted in community urology practices in the US.

Respiratory infections caused by the human fungal pathogen Aspergillus fumigatus are a major cause of mortality for immunocompromised patients. Exposure to these pathogens occurs through inhalation, although the role of the respiratory epithelium in disease pathogenesis has not been fully defined. Employing a primary human airway epithelial model, we demonstrate that fungal melanins potently block the post-translational secretion of the chemokines CXCL1 and CXCL8 independent of transcription or the requirement of melanin to be phagocytosed, leading to a significant reduction in neutrophil recruitment to the apical airway both in vitro and in vivo.

Host recognition of the pathogen-associated molecular pattern (PAMP), β-1,3-glucan, plays a major role in antifungal immunity. β-1,3-glucan is an essential component of the inner cell wall of the opportunistic pathogen . Most β-1,3-glucan is shielded by the outer cell wall layer of mannan fibrils, but some can become exposed at the cell surface.

C-type lectin receptors (CLRs) expressed by myeloid cells constitute a versatile family of receptors that play a key role in innate immune recognition. Myeloid CLRs exhibit a remarkable ability to recognize an extensive array of ligands, from carbohydrates and beyond, and encompass pattern-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs), and markers of altered self. These receptors, classified into distinct subgroups, play pivotal roles in immune recognition and modulation of immune responses.

Purpose: Germline genetic testing (GT) is important for prostate cancer (PCA) management, clinical trial eligibility, and hereditary cancer risk. However, GT is underutilized and there is a shortage of genetic counselors. To address these gaps, a patient-driven, pretest genetic education webtool was designed and studied compared with traditional genetic counseling (GC) to inform strategies for expanding access to genetic services.

Microbial species capable of co-existing with healthy individuals, such as the commensal fungus exploit multifarious strategies to evade our immune defenses. These strategies include the masking of immunoinflammatory pathogen-associated molecular patterns (PAMPs) at their cell surface. We reported previously that actively reduces the exposure of the proinflammatory PAMP, β-1,3-glucan, at its cell surface in response to host-related signals such as lactate and hypoxia.

Many models of choice assume that people retrieve memories of past experiences and use them to guide evaluation and choice. In this paper, we examine whether samples of recalled past experiences do indeed underpin our evaluations of options. We showed participants sequences of numerical values and asked them to recall as many of those values as possible and also to state how much they would be willing to pay for another draw from the sequence.
