ObjectiveCancer-related communication is critical for patients’ and caregivers’ adaptation to illness. This randomized pilot study was conducted to test the feasibility, acceptability, and efficacy of a specific dyadic intervention to improve communication.MethodsA four weekly-session intervention was developed to reinforce cancer-related patient-caregiver communication. Patients receiving treatment for any diagnosed cancer, and their caregivers, were recruited from two oncology clinics in Belgium. Sixty-four patient-caregiver dyads were assigned randomly to intervention and waitlist groups. Cancer-related dyadic communication, dyadic coping and emotional distress were assessed at baseline and post-intervention.ResultsThe intervention attrition rate was 6 %. Linear mixed models were performed on 60 dyads. Significant two-way group × time interaction indicated improvement in participants’ cancer-related dyadic communication frequency (β = ?1.30; SE = 0.31; p = .004), self-efficacy (β = ?10.03; SE = 3.90; p = .011) and dyadic coping (β = ?5.93; SE = 2.73; p = .046) after the intervention.ConclusionThese results indicate that the brief dyadic communication intervention is feasible and acceptable, and show preliminary evidence of efficacy.Practice implicationsEncouraging patients and caregivers to discuss personal cancer-related concerns may improve their ability to cope with the illness together. 相似文献
In routine susceptibility testing of Gram-negative bacteria, a particular resistance phenotype was observed: an Escherichia coli isolate from a urine sample exhibited resistance solely to mecillinam (MEC) but was fully susceptible to other β-lactam antibiotics (MEC-R-BL-S). The objectives as this study were to determine the prevalence of this phenotype and to describe the phenotype, molecular epidemiology and genetic background. Between 1 January 2014 and 31 January 2016, MEC-R-BL-S E. coli isolates from urine were collected and genes previously reported as mostly involved in MEC resistance were analysed. The genetic relatedness among isolates was investigated by repetitive element sequence-based PCR (rep-PCR) and multilocus sequence typing (MLST). Ten MEC-R-BL-S isolates were collected, accounting for 0.4% (10/2547) of all E. coli obtained from urine samples, 0.9% (10/1135) of ampicillin-susceptible E. coli isolates and 9.6% (10/104) of MEC-R E. coli isolates. The isolates appeared as small colonies with round morphology and had impaired fitness. The isolates were not clonal and belonged to various extraintestinal or commensal E. coli phylogroups. Mutations in the cysB gene were evidenced in all clinical isolates. In conclusion, microbiologists should be aware of these isolates with a particular susceptibility phenotype, which is not due to error in disk diffusion but is a real non-enzymatic antibiotic resistance pattern. 相似文献
Background: Angiotensin receptor blockers (ARBs) can induce or exacerbate psoriasis. Psoriasis is unlisted in the Summary of Product Characteristics (SmPC) of ARBs. We aimed to investigate the association between psoriasis and ARB exposure.
Methods: We reviewed spontaneous reports recorded in the French national Pharmacovigilance Database (FPVD). The association between psoriasis and ARB exposure was assessed using the case/non-case method. We also analyzed literature reports.
Results: We identified 89 reports of psoriasis during ARB exposure in the FPVD. Time to onset was most often less than 1 year. Outcome was favorable in 67% of reports after ARB discontinuation. Almost all ARBs were concerned. The reporting odds ratio (ROR) for psoriasis with this therapeutic class was 4.86 (95%CI 3.92–6.03). In the literature, we found 14 published reports of psoriasis with ARB exposure. Time to onset ranged from 6 weeks to 9 months. Outcome was also favorable after ARB discontinuation in the literature.
Conclusions: This underestimated adverse drug reaction is a class effect, time to onset is most often less than 1 year and outcome seems favorable after ARB discontinuation. The case/non-case approach highlights a potential safety signal. The SmPC of ARBs should be updated, increased awareness among healthcare professionals is warranted. 相似文献
Bone infections are difficult to treat and can lead to severe tissue destruction. Acute bone infections are usually caused by Staphylococcus aureus. Osteoclasts, which belong to the monocyte/macrophage lineage, are the key cells in bone infections. They are not well equipped for killing bacteria and may serve as a reservoir for bacterial pathogens. Silver has been known for centuries for its bactericidal activity. Here, we investigated the bactericidal effects of nano-silver particles in bacteria infected human osteoclasts. We found that nano-silver in per se non-toxic concentration enhanced the bactericidal activity in osteoclasts against intracellular Methicillin-resistant, virulent Staphylococcus aureus. The reduced bacterial survival in nano-silver pretreated cells correlated with increased reactive oxygen responses towards the invading pathogens. Overall, these results indicate that nano-silver compounds should be considered as an effective treatment and prevention option for bacterial bone and orthopedic implant infections. 相似文献
To explore efficacy and safety of Botulinum Neurotoxin Type A (BoNT-A) prostatic injection in patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperperplasia.
Materials and methods
A phase 3 multicenter open-labeled study randomised patients to receive BoNT-A prostatic injection or optimized medical therapy. BoNT-A injection consisted in trans-rectal injections of 200 UI in the transitional zone of the prostate. Optimal medical therapy consisted in oral medication with any drug patented for LUTS. One month (M1) after randomisation patients in the BoNT-A group were asked to stop any medical therapy related to LUTS. The main judgment criterion was the IPSS score at M4. Per-protocol analysis was performed with a non-inferiority hypothesis (ΔIPSS < 3).
Results
127 patients were randomised to BoNT-A (n = 64) or medical therapy (n = 63). At randomisation mean IPSS was 16.9 ± 7.2 in the BoNT-A group vs 15.7 ± 7.3 in control. In the BoNT-A group, 44 patients (73.3%) could interrupt medical therapy for LUTS from M1 to M4. At M4, mean IPSS score was 12.0 ± 6.7 in the BoNT-A group vs 11.8 ± 6.9 in control. After adjustment for baseline IPSS, delta IPSS between groups was 0.01; 95% CI [? 2.14; 2.11] leading to accept the non-inferiority hypothesis.
Conclusions
Four months after BoNT-A injection, most of the patients could interrupt LUTS-related medical treatments. In these patients, IPSS improvement was not inferior to optimized medical treatment, but the study design did not allow to conclude that this improvement was related with study drug rather than with sustained placebo effect.
Clear cell meningioma (CCM) is a rare grade II histopathological subtype that usually occurs in young patients and displays high recurrence rate. Germline SMARCE1 mutations have been described in hereditary forms of this disease and more recently in small syndromic and sporadic CCM series. The diagnostic value of SMARCE1 in distinguishing between CCM and other meningioma variants has not been yet established. The aim of our study was to investigate the status of SMARCE1 in a series of CCMs and its morphological mimickers. We compared the performance of an anti‐SMARCE1 antibody and the molecular analysis of the SMARCE1 gene in a retrospective multicenter series of CCMs. All CCMs lossed SMARCE1 immunoexpression. Bi‐allelic inactivating events were found by NGS‐based sequencing in all of these cases, except for one, which was incompletely explored, but had a wild‐type sequence. We then validated the anti‐SMARCE1 antibody specificity by analyzing additional 305 pediatric and adult meningiomas of various subtypes and 15 non‐meningioma clear cell tumors by SMARCE1 immunohistochemistry. A nuclear immunostaining was preserved in all other meningioma variants, as well as non‐meningioma clear cell tumors. In conclusion, our series showed, for the first time, that SMARCE1 immunostaining is a highly sensitive biomarker for CCM, useful as a routine diagnostic biomarker. 相似文献
