Risultati per: Terapia antibiotica: breve durata vs. lunga durata

To the Editor A recent study evaluating the safety and efficacy of roflumilast cream, 0.3%, for chronic plaque psoriasis involving 2% to 20% of body surface area concluded that daily use of roflumilast cream for 8 weeks was more effective than vehicle cream. We would like to point out some limitations of this study that decrease its generalizability.

To the Editor We have several comments about the recent study that concluded that nasal swabs collected by children and adolescents have similar diagnostic performance to those collected by health care professionals.

In Reply We appreciate the letter from Drs Hong and Sung about our study, which demonstrated the ability of children and adolescents to self-collect samples for respiratory virus testing and independently participate in their medical care.

Stroke, Volume 54, Issue Suppl_1, Page AWMP35-AWMP35, February 1, 2023. Background:Long-term disability after stroke is standardly assessed 3m post-onset, using the modified Rankin Scale (mRS), but clinical trial patients lost to follow-up require imputation of likely outcome. An early post-onset, e.g. day 4, mRS is often available but its utility to forecast outcome in ischemic and in hemorrhagic stroke patients has not been delineated.Methods:We analyzed all patients with acute cerebral ischemia (ACI) and with intracranial hemorrhage (ICH) enrolled in the NIH Field Administration of Stroke Therapy- Magnesium (FAST-MAG) Phase 3 trial. The performance of ordinal day 4 mRS, alone and as part of multivariate models, in predicting ordinal day 90 mRS was assessed using Spearman correlation coefficients (rs) and kappa (chance corrected agreement) statistics.Results:Among the 1206 acute cerebral ischemic patients, age was 70.9, 45.5 % were female, and initial NIHSS was 9.28 ± 8.28. In univariate analysis, day 4 mRS and day 90 mRS correlated strongly, rs= 0.76, weighted kappa = 0.71 increasing in multivariate analysis to rs= 0.78 and weighted kappa = 0.76 (Figure 1A). Among the 367 intracranial hemorrhage patients, age was 65.4, 32.7% were female, and initial NIHSS was 18.3 ± 11. In univariate analysis, day 4 mRS and day 90 mRS also correlated moderately rs= 0.64, weighted kappa = 0.63, increasing in multivariate analysis to rs= 0.81 and weighted kappa = 0.78 (Figure 1B). In the multivariate predictive models, day 4 mRS was the most determinative variable along with age and initial NIHSS for both ICH and ACI.Conclusion:For both acute cerebral ischemia and intracranial hemorrhage patients, long-term, 3m mRS disability outcomes can be predicted well using mRS assessment on day 4, alone and even more accurately in combination with baseline prognostic variables. Age and baseline NIHSS exert more additional influence on 3m mRS outcome in ICH than ACI, likely reflecting the better functional recovery among ICH than ACI stroke survivors.

Stroke, Volume 54, Issue Suppl_1, Page A23-A23, February 1, 2023. Background:First-pass effect (FPE) defined as a complete or near-complete reperfusion achieved after a single thrombectomy pass is predictive of favorable outcome in acute ischemic stroke (AIS) patients with large vessel occlusion. It remains uncertain whether intravenous tirofiban is effective to improve the rate of FPE in anterior circulation strokes.Methods:RESCUE-BT (A randomized controlled trial of intravenous tirofiban or placebo prior to endovascular thrombectomy for large vessel occlusion stroke) enrolled 948 patients with proximal intracranial large vessel occlusion presenting within 24 hours of time last known well to receive intravenous either tirofiban or placebo before endovascular thrombectomy. Patients who did not treated with endovascular thrombectomy were excluded from this cohort. The endpoint was FPE, which defined by extended thrombolysis in cerebral infarction (eTICI) scale 2b, 2c or 3 after the first pass. A modified Poisson regression analysis was performed to assess the association between intravenous tirofiban treatment and FPE.Results:Twenty-two patients were excluded for not treating with endovascular thrombectomy. The remaining 926 patients were included (mean age, 66 years; 380 [41.0%] women), with 450 in the tirofiban and 476 in the placebo group, respectively. Among them, an FPE was achieved in 141 patients (31.3%) of the tirofiban group vs 114 patients (23.9%) of the placebo group. The adjusted risk ratio for FPE with tirofiban vs placebo was 1.24 (95%CI, 1.02-1.52).Conclusions:Treatment with intravenous tirofiban before endovascular thrombectomy significantly increased the incidence of FPE in acute ischemic stroke patients with large vessel occlusion presenting within 24 hours of time last known well.

Stroke, Volume 54, Issue Suppl_1, Page AWP1-AWP1, February 1, 2023. Introduction:Patients with large vessel occlusion stroke (LVO) benefit from thrombolysis before thrombectomy. Previous meta-analysis suggested superiority of tenecteplase over alteplase in achieving good clinical outcome at 3 months.Aim:We aimed to compare clinical outcomes after tenecteplase 0.25 mg/kg versus alteplase in patients with LVO.Methods:An experienced librarian searched PubMed and Scopus databases through July 13, 2022 for randomized controlled trials comparing tenecteplase with alteplase in patients with LVO. We included trials using 0.25 mg/kg tenecteplase dose, reporting blindly assessed pre-specified clinical outcomes at 3-4 months among patients with LVO. Two authors independently reviewed eligibility and extracted the data. We used RevMan 5.4 and random effect models with inverse variance weights to calculate odds ratios (OR) and 95% confidence intervals (CI). This systematic review is registered (CRD42022349414).Results:From 585 retrieved abstracts, 3 trials and 1 pooled secondary analysis involving 704 unique patients met the inclusion criteria. Among patients with LVO, tenecteplase 0.25mg/kg is not superior to alteplase in achieving good clinical outcome (defined as modified Rankin Scale [mRS] 0-2, OR 1.82 (95% CI 0.91-3.65, panel A); nor all-cause mortality, OR 0.75 (95% CI 0.49-1.13, panel B); while tenecteplase increases the odds of excellent outcome (mRS 0-1), OR 1.52 (95% CI 1.11-2.09, panel C), and odds of functional improvement (defined as a shift on the ordinal mRS), OR 1.54 (95% CI 1.07-2.20, panel D). High heterogeneity was present (I2 =70%) for the good clinical outcome.Conclusion:Tenecteplase is not superior over alteplase in achieving good clinical outcome. Tenecteplase, as compared to alteplase, increases the odds of functional improvement and excellent outcome. These findings support bridging tenecteplase in patients with LVO.

Stroke, Volume 54, Issue Suppl_1, Page AWP113-AWP113, February 1, 2023. Introduction:Brain-selective hypothermia is a promising neuroprotectant in acute ischemic stroke. However, a non-invasive bedside method to monitor brain temperature during cooling is lacking. We tested the feasibility and accuracy of measuring brain temperature non-invasively using sensors designed to monitor core body temperature.Methods:In this prospective single-center study, 20 patients with large or medium vessel occlusion strokes were enrolled. Patients underwent a 3T MR spectroscopy imaging (MRSI, the reference standard) and zero heat flux (ZHF) core temperature sensor measurements (3MTMBair HuggerTM) within 12-72 hours from admission. Two ZHF sensors were placed on each side of the forehead on the side of stroke and contralateral side and the temperatures were checked before and after MRSI. A 2x2x2 cm voxel was centered on the infarct and matching contralateral location using diffusion weighted imaging. Brain temperature on MRSI was calculated using the relative chemical shifts of water and N-acetyl aspartate. Temperature measurements of the ZHF sensors were compared to MRSI measurements.Results:The brain temperature of stroke and contralateral sides were similar using MRSI or using ZHF sensors when each modality was compared to itself by hemisphere (all p >0.05). However, there was a significant difference for the ipsilateral side: median (SD) temperatures using MRSI was 36.0°C (1.8) vs 36.8°C (0.5) for sensor measurement. Bland-Altman plots showed that 95% of the observations fell within upper and lower limits of agreement of -2.1 to +3.7°C while 61% of observations fell within an agreement limit of +/- 1°C. There was an indication of an overall higher temperature measurements using the ZHF sensors compared to MRSI (Figure 1).Conclusions:More studies are needed to validate the use of ZHF thermometry in ischemic stroke including studies implementing hypothermia.Figure 1.

Stroke, Volume 54, Issue Suppl_1, Page ANS1-ANS1, February 1, 2023. Background:Post-stroke depression (PSD) affects up to one-third of stroke survivors and remains under-recognized. The optimal time for PSD screening seems to be about 30-45 days post-stroke. However, screening and follow up remains insufficient.Methods:Our stroke certified registered nurse contacted stroke patients admitted to Kaiser Permanente Los Angeles in 2021 to assess depression within 30-45 days post discharge using the Patient Health Questionnaire Screening Tool (PHQ9). Two call attempts were made. Based on the PHQ9 scores, patients were referred to different clinical care pathways. Patients who scored10-19 were referred to depression care management (DCM), while 20 and above were referred to psychiatry directly. We collected the demographics, stroke types and discharge disposition inpatients who were lost to follow up and patients who completed the follow up. Data were analyzed using R-Statistics.Results:Among 92 patients, 41 (45%) had follow-up depression screening completed; 13 (32%)received psychiatry referral given severity of depression, and 28 (68%) received a depression care management referral. Of 51 patients who did not complete follow-up screening, 27 (53%)declined to participate in screening, while 22 (43%) could not be reached. Patients who did not receive follow-up screening were older (P=0.02). Race, gender, discharge mRS or length of acute hospital stay did not have a significant effect on patient’s depression screening follow-up status. Patients discharged home with home health showed a trend for better completed follow-ups despite not reaching statistical significance (P=0.07).Conclusion:Raising awareness about the necessity of depression screening and its treatment is of utmost importance for reaching optimal recovery and rehabilitation potential in stroke patients. Post-discharge follow-up and education can be implemented to narrow the PSD recognition gap.
