Wide fluctuations in placebo responses have been reported in phase 3 trials of systemic therapies for moderate-to-severe plaque psoriasis.

In this systematic review and meta-analysis, we assessed placebo responses in phase 3 trials of systemic therapies for moderate-to-severe plaque psoriasis. The medical databases PubMed Medline, Embase, and Web of Science were searched for studies reporting on phase 3 psoriasis trials. A proportion meta-analysis determined the proportion of placebo-treated psoriasis patients obtaining a 75, 90, or 100% reduction in Psoriasis Area and Severity Index (PASI), that is, PASI75, PASI90, or PASI100, respectively, at week 12. In the assessment of PASI75 response, 44 trials with a total number of 7,972 patients were included.

In pooled analyses, 5.2% (95% CI 4.7-5.7%) obtained PASI75, 2.1% (95% CI 1.7-2.4%) obtained PASI90, and 0.3% (95% CI 0.1-0.5%) obtained PASI100 among placebo receivers. selleck inhibitor No temporal changes were observed. The overall proportion of placebo responders in phase 3 psoriasis trials is low and does not appear to be increasing in recent years.

Neurogenic lower urinary tract dysfunction (NLUTD) represents a severe burden for patients with open spina bifida (OSB). The effect of fetal OSB repair on the urological outcome remains unclear, as controversial data exist. The aim of this study was to further increment existing outcome data and to demonstrate that our earlier published positive preliminary results are not erratic.

Data from standardized urological follow-up appointments of patients with fetal OSB repair operated at our center were analyzed. Data were obtained from urodynamic studies (UDSs) and radiologic exams performed in the newborn (gestational age 37-39 weeks), at ages of 6, 12, 18, and 24 months, and then at yearly intervals.

Of 82 patients (mean age 2.6 years, range 6 months to 7 years), 26 (32%) had a normal bladder function as demonstrated by UDSs. Of the 56 (68%) patients with NLUTD, 29 (51%) patients showed initially a normal UDS, but developed NLUTD in the follow-up, 19 (66%) of them spontaneously and another 10 (34%) in association with growth and development, or surgery of inclusion cysts. Radiologic abnormalities (upper tract dilatation and vesico-uretero-renal reflux) were seen in 15%, mainly patients with NLUTD.

Our results add an important set of information to the existing body of evidence. The data reconfirm our earlier published favorable preliminary results and support other studies that show a possible benefit of prenatal OSB repair on the urological outcome, but they also demonstrate that the positive effect remains limited.

In triple negative breast cancer (TNBC) patients receiving neoadjuvant chemotherapy (NACT), pre-treatment predictors for pathological complete response (pCR) have been reported; however, those for progressive disease (PD) remain unidentified.

We investigated pre-treatment clinicopathological predictors associated with pCR and PD by retrospectively reviewing data for 165 patients treated between 2015 and 2018. Patients with pCR and PD were compared to those without pCR and PD, respectively, using logistic regression and Kaplan-Meier methods.

Lack of androgen receptor (AR) was an independent predictor of pCR, while high histological grade, low Ki-67 index, and incomplete NACT courses were independent predictors of PD. Mean disease-free survival and overall survival were significantly poorer in PD patients than in pCR patients (15.7, 21.3 vs. 52.4, 56.3 months).

Insights into the chemo-resistance mechanisms and exploration of novel targeted agents in subgroups as per AR and Ki-67 status are needed to improve survival outcomes in TNBC patients.

Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) are episodes of acute respiratory worsening characterized by diffuse alveolar damage superimposed on usual interstitial pneumonia. Direct hemoperfusion with a polymyxin B-immobilized fiber column (PMX-DHP) is reported to have beneficial effects on the respiratory status and outcome in patients with AE-IPF although its mechanism of action is not fully elucidated.

To investigate whether and how the PMX-immobilized fiber (PMX-F) adsorbs cytokines because reduction of the serum levels of various cytokines has been noted in AE-IPF patients receiving PMX-DHP.

The propensity of recombinant cytokines for adsorption onto PMX-F was examined by incubating cytokines with heparin-coated or uncoated PMX-F for 2 h at 37°C. Cytokines were quantitated by multiplex bead array assay or ELISA.

Interleukin (IL)-8, RANTES, platelet-derived growth factor-bb, and transforming growth factor-β were substantially adsorbed onto PMX-F without heparin coating. The adsorimpacts of PMX-DHP in patients with AE-IPF.

While cochlear implantation may have a positive effect on tinnitus, it is not effective in reducing tinnitus in all patients. This may be due to different patients requiring different strategies of electrical stimulation in order to obtain a positive effect on tinnitus. It is, therefore, important to identify the most effective stimulation strategies to reduce tinnitus. The simplest possible strategy is stimulation by only one electrode. In this study, we investigated tinnitus suppression by electrical stimulation via a single electrode of the cochlear implant.

We performed a listening experiment in 19 adult participants, who had received a unilateral cochlear implant (CI) because of severe bilateral hearing loss. All of these patients had indicated that they suffered from tinnitus. During a 300-s interval, patients listened to blocks of single-electrode stimulation and rated the loudness of the stimulus and any effects on their tinnitus. The 300-s interval included a block of single-electrode stimulation (duration 120 s).
