RESUMO

BACKGROUND: Prior reports have shown the utility of conventional lipiodol-based transarterial chemoembolization in hepatoblastoma. The authors describe the first reported case of hepatoblastoma treated with drug-eluting bead transarterial chemoembolization (DEB-TACE). OBSERVATIONS: An 11-month-old infant presented with hepatoblastoma measuring 14.3 cm. A trial of cisplatin chemotherapy followed by sequential DEB-TACE to the tumor's feeding vasculature reduced the mass to 5.3 cm. The patient tolerated both sessions of DEB-TACE without any major complication. Having demonstrated adequate disease control, the patient then underwent successful liver transplantation. CONCLUSION: This report provides promising evidence for the treatment of hepatoblastoma with DEB-TACE.

RESUMO

Objective: While hearing loss is associated with loneliness, the long term impact of hearing loss interventions remains unknown. We investigated levels of loneliness in adults at baseline, 6-months, 1-year and 5-years after receiving a hearing aid (HA) or cochlear implant (CI). Design: In this 5-year follow-up to the Studying Multiple Outcomes after Aural Rehabilitative Treatment study, participants completed the University of California, Los Angeles (UCLA) Loneliness Scale at baseline, 6-months, 1-year, and 5-year time points. Generalized estimating equations modeled the population average UCLA score over time. Study Sample: Analytic cohort of 115 participants (74% of original 156) 50 years or older who received a HA or CI at baseline and completed at least one follow up visit. Results: Loneliness scores were not different at 5 years versus baseline for HA users. CI users showed significantly reduced loneliness at 6-months and 1-year from baseline and with no significant difference at 5 years. Conclusion: Over 5 years, we observed no increase in loneliness from baseline in a cohort of adults receiving HAs and CIs. Short-term reduction in loneliness in CI users was demonstrated. Future randomized trials are needed to definitively assess the impact of treated versus untreated hearing loss on loneliness.

RESUMO

The nosocomial pathogen Candida albicans forms biofilms on medical devices that persist in the face of antifungals and host defenses. Echinocandins, the most effective antibiofilm drugs, have recently been shown to augment the activity of neutrophils against biofilms through an unknown mechanism. Here, we show that treatment of C. albicans biofilms with subinhibitory concentrations of echinocandins promotes the formation of neutrophil extracellular traps (NETs), structures of DNA, histones, and antimicrobial proteins with antifungal activity.

RESUMO

Infections with Staphylococcus aureus are a continuing and growing problem in community and hospital settings. Preclinical animal modeling of S. aureus relies on experimental infection, which carries some limitations. We describe here a novel, spontaneous model of oral staphylococcal infection in double knockout mice, deficient in the receptors for IL-17 (IL-17RA) and interferon (IFN)-γ (IFNγRI), beginning at 6 to 8 weeks of age. IFNγRI(-/-)IL17RA(-/-) (GRAKO) mice developed progressive oral abscesses. Cytometric methods revealed extensive neutrophilic infiltration of oral tissues in GRAKO mice; further investigation evidenced that IL-17 predominated neutrophil defects in these mice. To investigate the contribution of IFN-γ signaling to this native host defense to S. aureus, we observed perturbations of monocyte recruitment and macrophage differentiation in the oral tissues of GRAKO mice, and CXCL9/chemokine ligand receptor (CXCR)3-driven recruitment of T-cell oral tissues and draining lymph nodes. To address the former finding, we depleted macrophages and monocytes in vivo from IL17RA(-/-) mice using liposomes loaded with clodronate. This treatment elicited oral abscesses, recapitulating the phenotype of GRAKO mice. From these findings, we propose novel collaborative functions of IL-17 and IFN-γ, acting through neutrophils and macrophages, respectively, in native mucocutaneous host defenses to S. aureus.

RESUMO

OBJECTIVES/HYPOTHESIS: Previous research has shown hearing handicap to be reduced following hearing aid use or cochlear implantation in short-to-medium follow-up periods, yet the impact of interventions for hearing loss on hearing handicap in the long term remains understudied. This article reports hearing handicap at 6 months, 12 months, and 5 years after either hearing aid provision or cochlear implantation. STUDY DESIGN: Observational study. METHODS: A study of 115 participants from the Studying Multiple Outcomes after Aural Rehabilitative Treatment (SMART) study cohort assessed self-reported hearing handicap using the Hearing Handicap Inventory for the Elderly Screening version (HHIE-S) at baseline, 6 months, 12 months, and 5 years. Generalized estimating equations (GEE) were used to estimate the population mean HHIE-S score over time, accounting for the correlated nature of repeated measures data, and multiple imputation with chained equations was performed to impute missing data. RESULTS: Compared to baseline, mean HHIE-S scores after hearing aid provision were significantly reduced at 6 months (mean = -7.96, 95% confidence interval [CI]: -10.40, -5.53), 12 months (mean = -6.58, 95% CI: -9.26, -3.90), and 5 years (mean = -4.58, 95% CI: -7.87, -1.30). After cochlear implantation, mean hearing handicap scores were also significantly lower compared to baseline at 6 months (mean = -8.18, 95% CI: -11.07, -5.30), 12 months (mean = -10.04, 95% CI: -12.92, -7.16), and 5 years (mean = -8.97, 95% CI: -12.92, -7.16). CONCLUSIONS: This study found short-term benefits from hearing aids and cochlear implantation on hearing handicap were maintained over 5 years. Laryngoscope, 131:1122-1126, 2021.

RESUMO

Acute pathology of the biliary tract including cholangitis and cholecystitis can lead to biliary sepsis if early decompression is not performed. This article provides an overview of the presenting signs and symptoms and role of interventional radiology in the management of patients with acute cholangitis or acute cholecystitis. It is especially important to understand the role of IR in the context of other treatment options including medical management, endoscopy, and surgery.

RESUMO

OBJECTIVE: Social isolation and loneliness are associated with increased mortality and higher health care spending in older adults. Hearing loss is a common condition in older adults and impairs communication and social interactions. The objective of this review is to summarize the current state of the literature exploring the association between hearing loss and social isolation and/or loneliness. DATA SOURCES: PubMed, Embase, CINAHL Plus, PsycINFO, and the Cochrane Library. REVIEW METHODS: Articles were screened for inclusion by 2 independent reviewers, with a third reviewer for adjudication. English-language studies of older adults with hearing loss that used a validated measure of social isolation or loneliness were included. A modified Newcastle-Ottawa Scale was used to assess the quality of the studies included in the review. RESULTS: Of the 2495 identified studies, 14 were included in the review. Most of the studies (12/14) were cross-sectional. Despite the heterogeneity of assessment methods for hearing status (self-report or objective audiometry), loneliness, and social isolation, most multivariable-adjusted studies found that hearing loss was associated with higher risk of loneliness and social isolation. Several studies found an effect modification of gender such that among women, hearing loss was more strongly associated with loneliness and social isolation than among men. CONCLUSIONS: Our findings that hearing loss is associated with loneliness and social isolation have important implications for the cognitive and psychosocial health of older adults. Future studies should investigate whether treating hearing loss can decrease loneliness and social isolation in older adults.
