The COVID-19 pandemic tested the capacity of intensive care units (ICU) to respond to a crisis and demonstrated their fragility. Unsurprisingly, higher than usual mortality rates, lengths of stay (LOS), and ICU-acquired complications occurred during the pandemic. However, worse outcomes were not universal nor constant across ICUs and significant variation in outcomes was reported, demonstrating that some ICUs could adequately manage the surge of COVID-19.

In the present editorial, we discuss the concept of a resilient Intensive Care Unit, including which metrics can be used to address the capacity to respond, sustain results and incorporate new practices that lead to improvement.

We believe that a resiliency analysis adds a component of preparedness to the usual ICU performance evaluation and outcomes metrics to be used during the crisis and in regular times.

The COVID-19 pandemic demonstrated the need for a resilient health system. Although this concept has been discussed for health systems, it was not tested in intensive care. Future studies should evaluate this concept to improve ICU organization for standard and pandemic times.

Most of the currently used scaffolds in regenerative endodontic procedures (REPs) are unsuitable for chairside clinical use. This study aimed to evaluate the effect of an injectable synthetic scaffold (Restylane Lyft) on human bone marrow mesenchymal stem cell (hBMSC) viability, proliferation, and osteo/dentinogenic differentiation in a regenerative endodontic organotype model (REM). hBMSC were loaded in an REM either alone (hBMSC group) or mixed with the Restylane Lyft scaffold (Restylane/hBMSC group) and cultured in basal culture medium (n = 9/group). hMSC on culture plates served as controls. Cell viability and proliferation were measured using AlamarBlue assay. The loaded REM was cultured in an osteogenic differentiation medium to measure alkaline phosphatase activity (ALP) and examine the expression of the osteo/dentinogenic markers using real-time reverse transcriptase polymerase chain reaction. Cell viability in all groups increased significantly over 5 days. The Restylane/hBMSC group showed significantly higher ALP activity and dentin sialophosphoprotein, osteocalcin, and bone sialoprotein genes expression than the hBMSC and the control groups. Restylane Lyft, a hyaluronic acid (HA) injectable, FDA-approved hydrogel, maintained cell viability and proliferation and promoted osteo/dentinogenic differentiation of hBMSC when cultured in an REM. Henceforth, it could be a promising chairside scaffold material for REPs.
Despite the involvement of subcortical brain structures in the pathogenesis of classic trigeminal neuralgia (CTN), the details of morphological abnormalities of basal ganglia to this disorder are still unknown. This study aimed to investigate potential changes in terms of volume and shape of subcortical regions in patients with CTN.

Forty-eight patients with CTN and 46 matched healthy subjects were recruited in the study. The whole-brain T1 anatomical data was acquired at a 3.0 Tesla scanner using a fast spoiled gradient recalled sequence (FSPGR). Vertex-wise analysis was applied to detect the alterations of volume and shape in each subcortical region in the patients with CTN compared to healthy controls. The relationships of morphological abnormalities in subcortical structures to the severity of orofacial pain and the affective disturbance in the patient group were examined using the multiple linear regression model.

No group difference was found about volumetric measurement in any of the subcortical regions. Vertex-wise analysis revealed areas of significant shape atrophy in bilateral putamen and bilateral pallidum in the patients with CTN compared to healthy controls. Besides, the patient group exhibited shape expansion in the head of the right caudate nucleus compared to healthy subjects. In addition, shape deformation in the head of the right caudate nucleus was positively associated with VAS score in CTN.

The patients with CTN display shape alterations in the specific subregions of basal ganglia, which may contribute to the pathophysiology of this refractory disorder and may be useful for translational medicine.

In the tropics, mistletoes are frequent parasitic plants, influencing different trophic levels involved with the host plant. Here, we investigated the direct and indirect influences of multiple partners involved in interactions between the mistletoe Psittachantus robustus and its host tree, Vochysia thyrsoidea. Fimepinostat chemical structure More specifically, we assessed if the presence of the mistletoe modified herbivory levels of its host by altering the diversity of associated insects. We found that insect feeding guild modulated mistletoe influence on insect community, and there were fewer species and individuals of leaf-chewing insects in parasitized than non-parasitized trees. Despite this decrease in leaf-chewing insects, there were increased levels of herbivory in parasitized plants. Mistletoes' presence did not influence the hemipteran sap-sucking insects, but this herbivore guild directly responded to the abundance of their associated ants. Overall, our study found empirical support for the crucial role of mistletoes on their host-associated organisms, ultimately shaping the herbivory levels of their tree hosts. By exposing the distinct effects of the different partners involved, our results shed light on the intricated interactions mediated by parasitic plants, opening the path for new investigations.Forty years ago, the introduction of a new electrophysiological technique, the patch clamp, revolutionized the fields of Cellular Physiology and Biophysics, providing for the first time the possibility of describing the behavior of a single protein, an ion-permeable channel of the cell plasma membrane, in its physiological environment. The new approach was actually much more potent and versatile than initially envisaged, and it has evolved into several different modalities that have radically changed our knowledge of how cells (not only the classical "electrically excitable "ones, such as nerves and muscles) use electrical signaling to modulate and organize their activity. This review aims at telling the history of the background from which the new technique evolved and at analyzing some of its more recent developments.
We investigated the cytologic findings of primary acquired nasolacrimal duct obstruction (PANDO) based on the thin-prep cytology method using sheath-guided dacryoendoscopy.

A retrospective review was conducted of 66 cases from 50 patients who were diagnosed with PANDO. Slit-lamp examination, the lacrimal irrigation test, and dacryocystography were performed for the evaluation of PANDO. The dacryocystography (DCG) findings were classified into primary and secondary change. Each patient was treated with transcanalicular dacryoplasty using catheter sheath-guided dacryoendoscopy (RUIDO Fiberscope, Fiber Tech Co., Ltd., Tokyo, Japan) and obtained cytologic specimens. The liquid-based thin-prep cytology method was used for the analysis of histopathology.

The cellular detection rate was as follows epithelial cells with 56 cases (84.8%), 33 cases (50.0%) with inflammatory cells, 1 case (1.5%) with mucin, and bacterial colonies with 2 cases (3.0%). In the dacryoendoscopic findings, all cases of a presence of pusprep cytology can be used to analyze histopathological changes of lacrimal passage in PANDO without invasive biopsy. These cytologic findings of lacrimal passage provide a better understanding of the pathogenesis of lacrimal passage in patients with PANDO.
Toinvestigate the effect of font choice on reading parameters by using the RADNER Reading Charts printed in two fonts (Helvetica vs. Times Roman) equalized in terms of x-height.

This is a cross-sectional study of 40 participants with healthy eyes (18 to 60years of age; mean 42.13 ± 12.28years). Reading performance was evaluated binocularly with RADNER Reading Charts printed in either Helvetica Neue (T1) Roman sans serif (Adobe) or Times New Roman PS Roman serif (Adobe). The test distance was 40cm. Reading charts were presented in random order. Reading acuity (RA), mean reading speed of all sentences read (MEAN-ALL RS), mean reading speed from 0.8 logRAD to 0.3 logRAD (MEAN-RS), maximum reading speed (MAX-RS), and critical print size (CPS) were compared.

The RA values obtained for the Helvetica and Times Roman fonts (in full logarithmic units of 0.1 logRAD) did not differ between the two fonts (mean for both fonts - 0.128 ± 0.064 logRAD; 95% CI for both - 0.148; - 0.107 logRAD). The differences in all other reading parameters between the two fonts were small and not statistically significant. The analyses revealed narrow confidence intervals and good coefficients of reliability. Except for the CPS (r = 0.49) and RA (equal for Helvetica and Times Roman), the correlations for all parameters were high, ranging from r = 0.92 to r = 0.98.

The equivalent reading performance obtained with Helvetica and Times Roman (when equalized in x-height and layout) makes these font types interchangeable as standards for reading charts.

To verify the correct decision-making procedure on performing an intravitreal injection by investigating the in vivo wound morphology and evolution of 22-gauge wounds after dexamethasone oblique injection with anterior segment optical coherence tomography (OCT).

Prospective, observational consecutive case series.

Subjects underwent a dexamethasone injection at University Eye Clinic of Turin. All the injections have been performed in an oblique (aka beveled or angled) fashion. Patients were divided according to the number of injections already performed with dexamethasone. Group 1 consisted of patients at the first injection, group 2 of patients at a second or more injection always in the same quadrant, and group 3 of patients at the second or more injection in a different quadrant. The incisions were imaged with the Heidelberg SPECTRALIS OCT device on postoperative days 1, 8, and 15. The main outcome measure was wound structure/characteristics (e.g., presence of gaping) as evaluated with OCT. Surgical ara via and the scleral damage, thus protecting the patient from complications. For the future, it is hoped that the operating microscope and intraoperative OCT will be used on every occasion.
