Amphibian and reptile diversity from Isla Santay (Durán, Ecuador) has been underestimated due to the lack of monitoring throughout the island. Historically, this island has also been affected by anthropic landscape changes which limit the occurrence of certain species and favors the dispersion of opportunistic or more tolerant species. Such species dynamics tend to be more evident on islands, since their isolation limits species’ mobility. We present an updated checklist of the herpetofauna of Isla Santay Durán, Ecuador, and report for the first time the occurrence of two introduced species, Anolis sagrei Duméril & Bibron, 1837, Brown Anole, and Hemydactylus frenatus Duméril & Bibron, 1836.

There is limited evidence regarding the effects of a pre-existing heart failure (HF) on the diagnostic yield of pulmonary embolism (PE) evaluation in the Emergency Department (ED).Electronic medical record of consecutive adults who underwent a computed tomography pulmonary angiogram (CTPA) in the ED at Loma Linda University Medical Center between June 1, 2019 and March 25, 2022 were reviewed. Repeat studies for the same patient and patients with unspecified HF diagnoses or isolated right ventricular HF were excluded. Key demographics, lab values and vital signs, relevant medications were collected. Primary outcome was the incidence of PE on CTPA compared between patients with and without pre-existing HF.A total of 2846 patients were included in the study (602 patients with HF and 2244 without). In total cohort, 11.7% (n = 334) of patients had PE found on CTPA. The incidence of PE on CTPA was lower among patients with a history of HF than patients without a history of HF (12.5% vs 9%). A history of pre-existing HF was associated with a lower odds ratio for a positive PE study (OR 0.13, 95%CI: 0.03-0.57) in multivariable analyses.In this study, we observed that the incidence of PE among patients who undergo CTPA was lower among patients with pre-existing HF compared to those without. Further studies should determine if HF is an important mitigating factor when risk stratifying patients for PE.

We describe a patient who developed bilateral temporal lesions due to a haemorrhagic stroke. One year after onset, he showed marked apperceptive prosopagnosia and could not name people from their voices, although he had spared semantic knowledge about people he could not name and could access this knowledge from people's voice. Importantly, the patient was able to retrieve proper name of persons after their description and was able to name sounds and songs; he could also retrieve proper names of monuments, towns and cartoon characters upon visual presentation. No further relevant cognitive impairment was present. This clinical picture represents the auditory counterpart of prosopanomia and could be defined 'phonoanomia'. This case report suggests that naming people from their voice implies specific retrieval processes, and pose specific constraints to theoretical models of person recognition.

Abstract: Antimicrobial peptides (AMPs) are small molecules belonging to innate immunity that act against bacteria, fungi, and viruses. With the spread of bacterial strains resistant to current antibiotics, the scientific community is deeply committed to the identification and study of new molecules with putative antimicrobial activity. In this context, AMPs represent a promising alternative to overcome this problem. To date, several databases have been built up to provide information on the AMPs identified so far and their physico-chemical properties. Moreover, several tools have been developed and are available online that allow to highlight sequences with putative antimicrobial activity and predict their biological activity. These tools can also predict the secondary and tertiary structures of putative AMPs, thus allowing molecular docking studies to evaluate potential interactions with proteins/ligands. In this paper, we focused our attention on online available AMPs databases and computational tools for biological activity and tertiary structure prediction, highlighting some papers in which the computational approach was successfully used. As the identification of peptides starts from the analysis of a large amount of data, we show that bioinformatics predictions are the best starting point for the identification of new sequences of interest that can be subsequently produced and tested.

Type II Diabetes mellitus (T2DM) is the most common of two types of Diabetes disease. T2DM is a metabolic disease characterized mainly by insulin resistance, reduction of insulin secretion, and hyperglycemia. T2DM is a major public health cause of concern not only by the increase in morbidity and mortality associated with patients with the disease, but also by the significant reduction in quality of life and productivity among the economically active population. Isolated hyperglycemia refers to patients with T2DM with normal fasting plasma glucose and no ketoacidosis. With the rise of T2DM and the presence of hidden symptoms, it is vital to determine a diagnostic sequence, blood-glucose control with sulfonylureas or insulin, and diet and exercise.

Objectives: The objective of the study was to assess medical care and pain management of 237 lumbar disk herniation cases treated from 2011 to 2021 in the Specialties Hospital CREHVITAL, Ambato-Ecuador, and to provide a set of standards for appropriate management. Methods: Retrospective, cross-sectional analysis of archives, and registries of patient’s data provided by the Specialties Hospital CREHVITAL, Ambato-Ecuador. Participants: A total of 237 patients with lumbar disk herniation received medical services from 2011 to 2021; outcome measures were: Pain management, patient characteristics, surgical procedures, and medication after surgery. Results: The 40–50 age range had the highest prevalence of lumbar disk herniation and a higher percentage of the pathology in men (66%) than in women. Of the 237 patients, magnetic resonance imaging (MRI) showed the highest lumbar disk herniation of the L4–L5 (101 men and 20 women), followed by herniation of the L5–S1 (59 men and 51 women). Two types of surgeries were performed: Classical surgery on 157 patients and microsurgery on 80 patients. The average period before receiving treatment was 1.5 years of maintaining back pain, and the early post-operative management consisted of patients receiving diclofenac, ketorolac, and ceftriaxone. Analgesics were used in 73.43% of patients. All cases required strict control, follow-up, and post-operative check-ups. Conclusion: This study provides essential and conclusive evidence and information on treated cases of lumbar disk herniation and its incidence in the medical field.

In December 2019 in China, after a pneumonia outbreak of unknown etiology, a new RNA virus has been identified and called Sars-CoV-2. Sars-CoV-2 induced severe respiratory infections, with global and rapid epidemic diffusion, designated coronavirus disease 2019 (Covid-19). Sars-CoV-2 infection can lead to severe complications, such as acute respiratory distress syndrome (ARDS) with progression to pulmonary fibrosis. Recent clinical studies described that in patients with severe Covid-19, MSC infusions, promote regenerative and reparative effects with anti-inflammatory and anti-fibrotic action. MSCs do not express ACE2 and TMPRSS2, the two main human receptors for host-pathogen interaction, and are not permissive to in vitro Sars-CoV-2 infection, making them suitable for clinical application. The aim of our study was to evaluate the safety and efficacy of MSCs as cellular therapy in ARDS secondary to Sars-CoV-2 in patients undergoing mechanical ventilation, in order to prevent pulmonary fibrosis. MSCs for infusions are thawed at 2x106/ml cellular concentration. The intravenous infusion protocol consists of two doses of third party allogenic MSCs at 1x106/Kg, 15 day apart. From April 2020, six adult patients median age 65 years, median body weight 80 Kg, in mechanical ventilation for ARDS secondary to Sars-CoV-2 infection have been treated. Early or late adverse events were not recorded. Four out six patients showed a significant gas exchange improvement with extubation within seven days from the first infusion. Our results underline the safety and efficacy of MSC infusions for ARDS patients in mechanical ventilation, supporting the need of a phase I/II clinical trial.

PurposeThere is a lack of research proving how electronic word-of-mouth (eWOM) is a valuable source of information in the hospitality industry for developing hotels' intellectual capital. To fill this gap, this study aims to examine hotel managers' decision-making processes regarding the acceptance and management of eWOM and its impact on the Italian hotel ecosystem.Design/methodology/approachThis work takes advantage of the previous contributions to present a hotel's decision-making process model regarding structural capital. It includes eWOM as a context variable and changes implemented as a dependent variable in a comprehensive model. The structural equation modelling applies to a database obtained through a survey addressed to Italian hotel managers.FindingsThe results show that eWOM plays an essential role in managers' motivations to explain hotel changes implementation. The hotel leverages eWOM information and interaction through structural, relational and human capital to enhance products, services and strategies.Research limitations/implicationsThis work contributes to the extant literature by providing a comprehensive framework to explain the consequences of eWOM knowledge management from the intellectual capital view in the Italian hotel ecosystem.Practical implicationsFor practitioners, this research demonstrates how hotel managers should accept and manage eWOM knowledge through intellectual capital to make determinant decisions that improve hotel performance.Originality/valueThere is a scarcity of research on modelling the acceptability and management of eWOM in the hotel ecosystem from practitioners' perspectives. This work is the first attempt to determine how eWOM knowledge management boosts hotel intellectual capital and improves service innovation and performance.

Despite evidence of abnormal affective processing as a key correlate of depression, specific attentional mechanisms underlying processing of emotions in familial risk for depression have yet to be investigated in a single study. To this end, the amplitude of the P300 and late positive potential (LPP) complex and cardiac deceleration were assessed during the passive viewing of affective pictures in 32 individuals who had family history of depression (without depressive symptoms) and in 30 controls (without depressive symptoms and family history of depression). Individuals with familial risk for depression revealed reduced P300-LPP amplitudes in response to pleasant and unpleasant stimuli relative to controls, and comparable P300-LPP amplitudes in response to pleasant and neutral stimuli. Controls, but not individuals with familial risk for depression, reported cardiac deceleration during the viewing of pleasant vs. neutral and unpleasant stimuli in the 0–3 s time window. Also, only individuals with familial risk for depression showed a prolonged cardiac deceleration in response to unpleasant vs. neutral stimuli. Overall, the present study provides new insights into the characterization of emotion-related attentional processes in familial risk for depression as potential vulnerability factors for the development of the disorder.

In this study, we explored whether Nutlin-3a, a well-known, nontoxic small-molecule compound antagonizing the inhibitory interaction of MDM2 with the tumor suppressor p53, may restore ligands for natural killer (NK) cell–activating receptors (NK-AR) on neuroblastoma cells to enhance the NK cell–mediated killing. Neuroblastoma cell lines were treated with Nutlin-3a, and the expression of ligands for NKG2D and DNAM-1 NK-ARs and the neuroblastoma susceptibility to NK cells were evaluated. Adoptive transfer of human NK cells in a xenograft neuroblastoma-bearing NSG murine model was assessed. Two data sets of neuroblastoma patients were explored to correlate p53 expression with ligand expression. Luciferase assays and chromatin immunoprecipitation analysis of p53 functional binding on PVR promoter were performed. Primary neuroblastoma cells were also treated with Nutlin-3a, and neuroblastoma spheroids obtained from one high-risk patient were assayed for NK-cell cytotoxicity. We provide evidence showing that the Nutlin-3a–dependent rescue of p53 function in neuroblastoma cells resulted in (i) increased surface expression of ligands for NK-ARs, thus rendering neuroblastoma cell lines significantly more susceptible to NK cell–mediated killing; (ii) shrinkage of human neuroblastoma tumor masses that correlated with overall survival upon adoptive transfer of NK cells in neuroblastoma-bearing mice; (iii) and increased expression of ligands in primary neuroblastoma cells and boosting of NK cell–mediated disaggregation of neuroblastoma spheroids. We also found that p53 was a direct transcription factor regulating the expression of PVR ligand recognized by DNAM-1. Our findings demonstrated an immunomodulatory role of Nutlin-3a, which might be prospectively used for a novel NK cell–based immunotherapy for neuroblastoma.

Immune checkpoint blockade therapy has changed prognoses for many melanoma patients. However, immune responses that correlate with clinical progression of the disease are still poorly understood. To identify immune responses correlating with melanoma clinical evolution, we analyzed serum cytokines as well as circulating NK and T-cell subpopulations from melanoma patients. The patients' immune profiles suggested that melanoma progression leads to changes in peripheral blood NK and T-cell subsets. Stage IV melanoma was characterized by an increased frequency of CCR7+CD56bright NK cells as well as high serum concentrations of the CCR7 ligand CCL19. CCR7 expression and CCL19 secretion were also observed in melanoma cell lines. The CCR7+ melanoma cell subpopulation coexpressed PD-L1 and Galectin-9 and had stemness properties. Analysis of melanoma-derived cancer stem cells (CSC) showed high CCR7 expression; these CSCs were efficiently recognized and killed by NK cells. An accumulation of CCR7+, PD-L1+, and Galectin-9+ melanoma cells in melanoma metastases was demonstrated ex vivo. Altogether, our data identify biomarkers that may mark a CCR7-driven metastatic melanoma pathway.

Characteristics of prostate tumors.

Correlation of mRNA for NK cell markers with prognosis in prostate cancer (public datasets).

The field of immunotherapy for solid tumors, such as prostate cancer, has been recently focusing on therapies that can counter tumor-mediated immunosuppression. Precise quantification and characterization of the immune infiltrates in tumors is crucial to improve treatment efficacy. Natural killer (NK) cells, major components of the antitumor immune system, have never been isolated from prostate tumors, despite their suspected role in disease progression. Here, we examined the frequency, phenotype, and functions of NK cells infiltrating control and tumor prostate tissues. NK cell infiltrates in prostate tissues were mainly CD56 (NCAM1)-positive and displayed an unexpected immature, but activated, phenotype with low or no cytotoxic potential. Furthermore, we show that TGFβ1 (TGFB1) is highly secreted into the prostate environment and partly mediates the immunosuppressive effects on NK cells. In addition to this basal level of immunotolerance to NK cells, the prostate environment became further resistant to NK cell–mediated immunity upon cancer cell infiltration. Coculture experiments revealed that prostate cancer cells induced the expression of inhibitory receptor (ILT2/LILRB1) and downregulated the expression of activating receptors NKp46 (NCR1), NKG2D (KLRK1), and CD16 (FCGR3) by NK cells, thus preventing their recognition of tumor cells. Notably, blood levels of NKp46 were also decreased in prostate cancer patients and were inversely correlated with levels of prostate-specific antigen, the main prognostic factor in prostate cancer. Our study shows that a strong immunosuppressive environment impairs NK cell function at multiple levels in prostate cancer and provides a rationale for the design of therapies that restore NK cell efficiency in the prostate tumor microenvironment.
