Abstract
BACKGROUND The efficacy of esketamine in treatment-resistant depression (TRD) has been confirmed. However, its administration is expensive and restrictive, with limited knowledge on how long the treatment should be continued. Predicting the treatment outcome would benefit patients and alleviate the global treatment cost. We aimed to define distinct trajectories of treatment response and assess their predictability. METHODS In this longitudinal study, two independent samples of patients with unipolar or bipolar TRD were treated with esketamine in real-world settings. Depression severity was assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS) before each esketamine administration. Latent class analyses were used to define trajectories of response. RESULTS In the original sample (N = 50), we identified two classes whose trajectories depicted response and non-response, respectively. The model was validated in the confirmatory sample (N = 55). Class membership was influenced by a few baseline characteristics such as concomitant benzodiazepine medication, number of depressive episodes or polarity. On the other hand, after only two esketamine administrations, the MADRS score predicted the 90-day trajectory of response with an accuracy of 80 %. LIMITATIONS This observational study is not placebo-controlled. Therefore, its results and their generalizability need to be confirmed in experimental settings. CONCLUSIONS After the first administrations of esketamine, the MADRS score has a good capacity to predict the most plausible trajectory of response. While thresholds and their predictive values need to be confirmed, this finding suggests that clinicians could base on MADRS scores their decision to discontinue treatment because of poor remaining chances of treatment response.

Abstract
The use of high-frequency Transcranial Magnetic Stimulation (HF-rTMS) of the right dorsolateral prefrontal cortex (DLPFC) in treating Post-traumatic Stress Disorder (PTSD) is currently regarded as a level B intervention (probable effectiveness). HF-rTMS has attracted interest as a neuromodulation therapeutic method for PTSD. Prolonged exposure and reactivation therapy are also regarded as first-line treatments for PTSD. Randomized controlled clinical studies examining the effectiveness of several HF-rTMS sessions coupled with psychotherapy have not yet been completed. In total, 102 patients with refractory PTSD will be randomly assigned (1:1) to reactivation therapy, in addition to either active HF-rTMS (20 Hz) or sham HF-rTMS, for 12 sessions in a nationwide, multicenter, double-blind controlled trial. The impact on PTSD symptoms and neurocognitive functioning will be assessed. The primary outcome is the PTSD severity score measured based on the Clinician-Administered PTSD Scale (CAPS-5) at one month. If this additional therapy is successful, it may strengthen the case for regulatory authorities to approve this additional technique of treating PTSD. Additionally, it expands the field of neurostimulation-assisted psychotherapy.

Abstract
AIMS To identify factors associated with in-hospital mortality, to estimate the intubation rate and to describe in-hospital mortality in patients over 65 years old with invasive mechanical ventilation (IMV) in the emergency department (ED). METHODS Retrospective cohort study of patients over 65 years old, who were intubated in an ED of a high complexity hospital between 2016 and 2018. Demographic data, comorbidities, and severity scores on admission were described. Bivariate and multivariate analyses were performed with logistic regression according to mortality and possible confounders. RESULTS A total of 285 patients with a mean age of 80 years required IMV in the emergency department, for a median of 3 days, and with a mean APACHE II score of 20 points of severity. The IMV rate was .48% (95% CI .43-.54), and 55.44% (158) died. Mortality-associated factors after age and sex adjustment were stroke (OR 2.13; 95% CI 1.21-3.76), chronic kidney failure, (OR 4.,38; 95% CI 1.91-10.04), Charlson index (OR 1.19; 95% CI 1.02-1.38), APACHE II score (OR 1.07; 95% CI 1.02-1.12), and SOFA score (OR 1.14; 95% CI 1.03-1.27). DISCUSSION Our IMV rate was lower than that stated by Johnson et al. in the United States in 2018 (.59%). In-hospital mortality in our study exceeded that predicted by the APACHE II score (40%) and SOFA (33%). However it was consistent with that reported by Lieberman et al. in Israel and Esteban et al. in the United States. CONCLUSIONS Although the IMV rate was low in the ED, more than half the patients died during hospitalization. Pre-existing cerebrovascular and renal diseases and high results in the comorbidities index and severity scores on admission were independent factors associated with in-hospital mortality.

Abstract
To determine the distribution of the epidermal growth factor (EGF) receptor (EGFR) on the surface of cells responding to EGF as a chemoattractant, an EGFR-green fluorescent protein chimera was expressed in the MTLn3 mammary carcinoma cell line. The chimera was functional and easily visualized on the cell surface. In contrast to other studies indicating that the EGFR might be localized to certain regions of the plasma membrane, we found that the chimera is homogeneously distributed on the plasma membrane and becomes most concentrated in vesicles after endocytosis. In spatial gradients of EGF, endocytosed receptor accumulates on the upgradient side of the cell. Visualization of the binding of fluorescent EGF to cells reveals that the affinity properties of the receptor, together with its expression level on cells, can provide an initial amplification step in spatial gradient sensing.
