Acinetobacter baumannii is a pathogenic bacterium commonly associated with multidrug resistance. In this issue of Antimicrobial Agents and Chemotherapy, Rao et al. present a challenging case of ventilator-associated pneumonia in which bacteriophage therapy was used as a last resort treatment in combination with systemic antibiotics (S. Rao, M. Betancourt-Garcia, Y. O. Kare-Opaneye, B. E. Swiercezewski, et al., Antimicrob Agents Chemother, 2021, https//doi.org/10.1128/AAC.00824-21). The data are promising, and several key areas are highlighted for future research.The objective of this study was to compare the rate of pneumonia resolution in obese (BMI ≥ 30 kg/m2) and non-obese (BMI less then 30 kg/m2) patients treated with ertapenem one gram daily. This was a retrospective cohort study evaluating patients treated at The Ohio State University Wexner Medical Center between January 1, 2015 and August 31, 2020. Patients were included if they were between 18 and 89 years old and received ertapenem for at least 48 hours for pneumonia. Patients were excluded if pregnant, incarcerated, had renal impairment, received antibiotics with gram-negative activity for a significant period prior to or in addition to ertapenem, and patients with other concomitant deep-seated infections. The primary outcome of clinical resolution was defined as meeting any of three criteria in order of evaluation discontinuation of antibiotics by day 8 of therapy, afebrile while on ertapenem in addition to a decrease in white blood cell count, or improvement on chest radiograph at day 7 of therapy. A multivariable logistic regression analysis was performed to examine the association between obesity and clinical resolution, while adjusting for proven confounders. There were 76 non-obese and 65 obese patients included. The median patient BMI was 23.7 kg/m2 (21.0-26.9) and 35.0 kg/m2 (32.8-39.8) for the non-obese and obese cohorts, respectively. Clinical resolution was achieved in 78% (59/76) of non-obese and 75% (49/65) of obese patients (p=0.75) without an observed difference in the regression model. Outcomes were similar in obese and non-obese patients treated with ertapenem one gram daily for pneumonia.Telacebec (Q203) is a potent drug candidate under clinical development for the treatment of drug-naïve and drug-resistant tuberculosis. The first-in-human randomized, placebo-controlled, double-blind, dose-escalation Phase 1A trial (Q203-TB-PI-US001) was conducted to evaluate the safety, tolerability, and pharmacokinetics of telacebec. A total of 56 normal, healthy, male and female subjects (42 active and 14 placebo) were enrolled in the study. The doses of telacebec were 10 mg (Cohort 1), 30 mg (Cohort 2), 50 mg (Cohort 3), 100 mg (Cohort 4), 200 mg (Cohort 5), 400 mg (Cohort 6), and 800 mg (Cohort 7) in a fasted state. Subjects participating in Cohort 4 were also enrolled in Cohort 8 to investigate the food effect on the pharmacokinetics of telacebec after a high-fat meal. In all subjects dosed with telacebec (10 - 800 mg), telacebec was well tolerated and did not lead to any significant or serious adverse events. Following a single oral administration of telacebec (10 - 800 mg), telacebec plasma concentration reached the maximal plasma concentration (Cmax) in average 2.0 - 3.5 h and showed multi-exponential decline thereafter. The area under the plasma concentration vs. time curve (AUC) was approximately dose-proportional. A significant increase in plasma concentrations was observed in the fed condition compared with the fasted condition with the geometric mean ratio of 3.93 for Cmax. Moderate delay in Tmax (4.5 h) was also observed in the fed condition. These results, combined with the demonstrated activity against drug-sensitive and multidrug-resistant Mycobacterium tuberculosis, support further investigation of telacebec for the treatment of tuberculosis.Research efforts to combat antimalarial drug resistance rely on quick, robust, and sensitive methods to genetically characterize Plasmodium falciparum parasites. We developed a single-nucleotide polymorphism (SNP)-based genotyping method that can assess 33 drug resistance-conferring SNPs in dhfr, dhps, pfmdr1, pfcrt, and k13 in nine PCR reactions, performed directly from P. falciparum cultures or infected blood. AZD9291 solubility dmso We also optimized multiplexed fragment analysis and gel electrophoresis-based microsatellite typing methods using a set of five markers that can distinguish 12 laboratory strains of diverse geographical and temporal origin. We demonstrate how these methods can be applied to screen for the multidrug-resistant KEL1/PLA1/PfPailin (KelPP) lineage that has been sweeping across the Greater Mekong Subregion, verify parasite in vitro SNP-editing, identify novel recombinant genetic cross progeny, or cluster strains to infer their geographical origins. Results were compared with Illumina-based whole-genome sequence analysis that provides the most detailed sequence information but is cost-prohibitive. These adaptable, simple, and inexpensive methods can be easily implemented into routine genotyping of P. falciparum parasites in both laboratory and field settings.Increased usage of daptomycin (DAP) for methicillin-resistant Staphylococcus aureus (MRSA) infections has led to emergence of DAP-resistant (DAP-R) strains, resulting in treatment failures. DAP-fosfomycin (Fosfo) combinations are synergistically active against MRSA, although the mechanism(s) of this interaction are not fully understood. The current study explores four unique, but likely interrelated activities of DAP-Fosfo combinations i) synergistic killing; ii) prevention of evolution of DAP-R; iii) resensitization of already DAP-R subpopulations to a DAP-susceptible (DAP-S) phenotype; and iv) perturbations of specific cell envelope phenotypes known to correlate with DAP-R in MRSA. Using an isogenic DAP-S (CB1483) / DAP-R (CB185) clinical MRSA strain-pair, we demonstrated that DAP + Fosfo combinations i) enhanced killing of both strains in vitro and ex vivo; ii) increased target tissue clearances of the DAP-R strain in an in vivo model of experimental infective endocarditis (IE); iii) prevented emergence of DAP-R in the DAP-S parental strain both in vitro and ex vivo; and iv) resensitized the DAP-R strain to a DAP-S phenotype ex vivo. Phenotypically, following exposure to sub-MIC Fosfo, the DAP-S/ DAP-R strain-pair exhibited distinct modifications in i) net positive surface charge (p less then 0.0001); ii) quantity (p less then 0.0001) and localization of cell membrane cardiolipin (CL); iii) DAP surface binding; and iv) membrane fluidity (p less then 0.0001). Furthermore, pre-conditioning to this strain-pair to DAP +/- Fosfo sensitized these organisms to killing by the human host defense peptide, LL37. These data underscore the notion that DAP-Fosfo combinations can impact MRSA clearances within multiple microenvironments, likely based on specific phenotypic adaptations.Background Timely and effective removal of respiratory secretions is of great significance for tracheotomized patients. The purpose of this study is to investigate the effectiveness of capsaicin nebulization to stimulate cough to promote early clearance of respiratory secretions in tracheotomized patients after hemorrhagic stroke. Method This study implemented a randomized controlled design. Sixty-three patients who were tracheotomized following a hemorrhagic stroke completed this randomized controlled trial. In the control group, 33 cases were given a routine care after tracheotomy. In the intervention group, 30 cases were given a capsaicin solution nebulization in addition to the routine care. The daily sputum output and the number of sputum suctioning were observed. The differences in sputum viscosity, cough function, and Clinical Pulmonary Infection Score (CPIS) were compared between the two groups before and after the intervention. Vital sign changes during capsaicin nebulization and suctioning were compared between the two groups in a pilot study. Results The daily sputum output of the capsaicin intervention group was significantly higher than that of the control group (p .05). Conclusions Capsaicin atomization-induced cough can effectively promote sputum excretion of hemorrhagic stroke patients undergoing tracheotomy and has a good safety profile. The Clinical Trial registration number of this study is ChiCTR2000037772 (http//www.chictr.org.cns). Supplemental Material https//doi.org/10.23641/asha.16821352.Introduction Adults with mild traumatic brain injury (mTBI) are at risk for communication disorders, yet studies exploring cognitive-communication performance are currently lacking. Aims This aim of this study was to characterize discourse-level performance by adults with mTBI on a standardized elicitation task and compare it to (a) healthy adults, (b) adults with orthopedic injuries (OIs), and (c) adults with moderate to severe TBI. Method This study used a cross-sectional design. The participants included mTBI and OI groups recruited prospectively from an emergency medicine department. Moderate to severe TBI and healthy data were acquired from TalkBank. One-way analyses of variance were used to compare mean linguistic scores. Results Seventy participants across all groups were recruited. Groups did not differ on demographic variables. The study found significant differences in both content and productivity measures among the groups. Variables did not appear sensitive to differentiate between mTBI and OI groups. Discussion Cognitive and language performance of adults with mTBI is a pressing clinical issue. Studies exploring language with carefully selected control groups can influence the development of sensitive measures to identify individuals with cognitive-communication deficits.[Figure see text].A nationally representative survey (N = 2,213) and five experiments (four preregistered, total N = 1,920) revealed that Whites perceived a foreign cultural threat, or a threat to their American culture and way of life, from the projected growth of racial and ethnic minority populations in their majority-White neighborhoods (Studies 1-5) and schools (Study 6). Whites perceived the increasing presence of Arab Americans, Latinos, and Asian Americans to pose an especially strong degree of perceived foreign cultural threat relative to Black Americans, who were perceived as more threatening than no demographic change. Furthermore, perceptions of foreign cultural threat predicted Whites' desires to move out above and beyond other established intergroup threats (e.g., realistic and symbolic threats). These findings highlight how Whites' concerns about losing their American culture and way of life as racial and ethnic minority groups enter majority-White neighborhoods and schools may contribute to the maintenance of racial segregation.

It may most usefully serve these functions when it is preferentially directed toward better cooperators. We examined this proposal in two studies with young children. Study 1 asked whether children forgive in-group members (whom people generally expect to be more cooperative) more than out-group members. When a novel in-group member and out-group member both transgressed against the child and both showed remorse, 5-year-old children (N = 20) were more forgiving of the in-group member. In Study 2, when only the out-group transgressor was remorseful whereas the in-group transgressor was unremorseful (and did not demonstrate cooperative intent), 5-year-olds (N = 20) were more forgiving of the remorseful out-group transgressor. Children also judged the unremorseful in-group transgressor negatively and wanted her to leave their group. Together, these results reveal that from early in life, forgiveness is preferentially directed so as to maximize successful cooperation while reducing the risk of exploitation.
