Published: July 2022

Las instituciones universitarias juegan un rol protagónico en el desarrollo del conocimiento científico y su desempeño deja huellas favorecedoras al desarrollo de toda nación; ya que son parte de un engranaje social que incide de manera radical en la definición de los derroteros por los que ellas enrumban el desarrollo de regiones y países. Este trabajo pretende abordar esta problemática desde el contexto de la pandemia Covid-19 relativo a la incidencia de estas instituciones como actores fundamentales del desarrollo de la sociedad. En este sentido se realizó un análisis conceptual de varias perspectivas y enfoques de la literatura científica, a partir de un análisis documental, tomando el criterio de autores contemporáneos de gran relevancia. Se enfatiza en la incidencia de las universidades en la innovación social como fenómeno impulsado desde la ciudadanía, y las comunidades que refuerzan la llamada tercera misión de estas instituciones académicas desde el enfoque del modelo de la triple hélice: gobierno-empresa-academia. Se concluye con los principales retos que distinguen el accionar de ellas en las contingencias actuales.

Mangrove (Avicennia marina) is a “green lung” tree growing along the Arabian Gulf coastline in the United Arab Emirates. Here, we aimed to determine the impact of the application of a commercial seaweed extract (SWE) biostimulant and endophytic actinobacterial isolates on growth performance and endogenous hormonal levels of mangroves. Therefore, we isolated endophytic plant growth-promoting (PGP) actinobacteria (PGPA) from mangrove roots and evaluated their potential as biological inoculants on mangrove seedlings under greenhouse and open-field nursery conditions. Seven salt-tolerant isolates had the ability to produce different levels ofin vitroplant growth regulators (PGRs) and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (ACCD) and to solubilize phosphorus. Accordingly, only one isolate,Streptomyces tubercidicusUAE1 (St), was selected based on its relative superiority in displaying multiple modes of action and in successfully colonizing mangrove tissues for 15 weeks. In the greenhouse experiments, plants treated withStand SWE significantly (p&lt; 0.05) improved dry biomass by 40.2% and 55.1% in roots and 42.2% and 55.4% in shoots, respectively, compared to seawater-irrigated non-treated mangrove plants (control). However,St+SWE caused a greater significant (p&lt; 0.05) increase in dry weight of roots (67.6%) and shoots (65.7%) than did control plants. Following the combined treatment ofSt+SWE,in plantaPGR levels were found to be greatly enhanced over the non-treated control plants grown in non-SWE supplemented sediments, or plants inoculated with onlySt without the supplementation with SWE,or with non-inoculated plants grown in sediments supplied with SWE only. This was evident from the significant (p&lt; 0.05) increases in the photosynthetic pigments and production of PGRs, as well as the reduction in the endogenous ACC levels of plant tissues compared to those in other treatments. Tissue nutrient contents of seedlings also increased by at least two-fold inSt+SWE treatment as compared to control. Similar effects were observed on all growth parameters under natural open-field nursery conditions. CombiningStwith SWE not only stimulates plant growth but also potentially has additive effects on mangrove ecosystem productivity in nutrient-impoverished soils in the Arabian coastal areas. This report is the first in the field of marine agriculture that uses SWE as a nutrient base for actinobacteria capable of producing PGRs and ACCD.

Published: July 2022

BackgroundDynamic functional network connectivity (dFNC) estimated from resting-state functional magnetic imaging (rs-fMRI) studies the temporally varying functional integration between brain networks. In a conventional dFNC pipeline, a clustering stage to summarize the connectivity patterns that are transiently but reliably realized over the course of a scanning session. However, identifying the right number of clusters (or states) through a conventional clustering criterion computed by running the algorithm repeatedly over a large range of cluster numbers is time-consuming and requires substantial computational power even for typical dFNC datasets, and the computational demands become prohibitive as datasets become larger and scans longer. Here we developed a new dFNC pipeline based on a two-step clustering approach to analyze large dFNC data without having access to huge computational power.MethodsIn the proposed dFNC pipeline, we implement two-step clustering. In the first step, we randomly use a sub-sample dFNC data and identify several sets of states at different model orders. In the second step, we aggregate all dFNC states estimated from all iterations in the first step and use this to identify the optimum number of clusters using the elbow criteria. Additionally, we use this new reduced dataset and estimate a final set of states by performing a second kmeans clustering on the aggregated dFNC states from the first k-means clustering. To validate the reproducibility of results in the new pipeline, we analyzed four dFNC datasets from the human connectome project (HCP).ResultsWe found that both conventional and proposed dFNC pipelines generate similar brain dFNC states across all four sessions with more than 99% similarity. We found that the conventional dFNC pipeline evaluates the clustering order and finds the final dFNC state in 275 min, while this process takes only 11 min for the proposed dFNC pipeline. In other words, the new pipeline is 25 times faster than the traditional method in finding the optimum number of clusters and finding the final dFNC states. We also found that the new method results in better clustering quality than the conventional approach (p &lt; 0.001). We show that the results are replicated across four different datasets from HCP.ConclusionWe developed a new analytic pipeline that facilitates the analysis of large dFNC datasets without having access to a huge computational power source. We validated the reproducibility of the result across multiple datasets.

ObjectiveThe role of stereotactic body radiation therapy (SBRT) for treating small hepatocellular carcinoma (sHCC) has gained increasing recognition. However, the prognosis and risk factors for recurrence in patients with sHCC remain unclear. This study investigated the risk factors for the recurrence of hepatitis B virus (HBV)-related sHCC after SBRT.MethodsA total of 240 HBV-related sHCC patients treated with SBRT between March 2011 and March 2020 were retrospectively analyzed. The cumulative probability of recurrence was calculated according to the Kaplan–Meier method. Univariate and multivariate analyses were performed with Cox proportional hazard models.ResultsRecurrent hepatocellular carcinoma developed in 134 (55.8%) patients at a median time of 27 months after SBRT. The one- and two-year rates of recurrence were 20.9 and 45.0%, respectively. The median follow-up time was 30 months. The Cox multivariate analysis indicated that age (P = 0.029, HR [1.019, 1.002–1.037]), tumor size (P = 0.012, HR [1.227, 1.045–1.440]), and aspartate aminotransferase-to-platelet ratio index (APRI) (P = 0.005, HR [1.911, 1.221–2.989]) were independent risk factors for recurrence.ConclusionPatients receiving SBRT for HBV-related sHCC may be at greater risk of recurrence if they have a high APRI score combined with advanced age and large tumor size.

Porphyran possesses various activities, while the effects of the porphyran from Porphyra haitanensis (PPH) on obesity are rarely reported. In this study, C57BL/6J male mice were fed with HFD combined with PPH gavage (50 mg/kg/d) for 16 weeks, and body weight was measured once a week. After that, serum, adipose, and liver tissues were collected for physiological and biochemical analyses. Our research indicated that PPH treatment alleviated obesity in HFD-fed mice. PPH alleviated fat accumulation in serum, liver, and adipose tissues. In addition, PPH activated the AMPK-HSL/ACC pathway in epididymal adipose tissue to reduce lipid accumulation. Moreover, PPH turned white adipose into brown and activated the PGC 1α-UCP 1-mitochondrial pathway in scapular adipose tissue to generate more heat. Interestingly, PPH regulated colonic microbiota homeostasis in obese mice, including significant elevation of Roseburia and Eubacterium and marked reduction of Helicobacter. Moreover, Spearman’s correlation analysis demonstrated that regulation of gut microbiota can decrease lipid accumulation. In summary, our study illustrated that PPH possesses the potential to be developed as an anti-obesity agent.

BackgroundThis pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates.MethodsSeventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform’s usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention from a practitioner’s point of view.ResultsThis study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format.ConclusionThis study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed.

Published: July 2022

IntroductionDignity therapy (DT) is brief psychotherapy targeting psychological and existential suffering among patients with a life-limiting illness. Studies have been conducted on the use of DT by healthcare professionals. In Italy, the current legislation defines that any form of psychotherapy may be performed exclusively by psychotherapists. Consequently, this intervention is unlikely to be used by other healthcare professionals. Herein, we will describe a training on DT not as a psychotherapy intervention but as a narrative intervention for non-psychotherapists health care professionals. Finally, we will explore the potential enablers/barriers as experienced by palliative care physicians and nurses.MethodsThe study was conducted in the Psycho-Oncology Unit within the Cancer Research Hospital of Reggio Emilia (Italy). It consisted of an exploratory qualitative case study. Data were collected employing observations and interview data and thematically analyzed.ResultsThe training was attended by six physicians and ten nurses and took place during two-afternoon sessions for 10 h. Two participants put their training into practice and administered DT under the supervision of a psychotherapist. Data analysis highlighted five overarching themes relating to the training experience and direct use of DT, namely, (i) time required, (ii) psychological skills, (iii) patient’s disease awareness, (iv) patient’s life history, and (v) distinguishing DT from Advance Care Planning.ConclusionPalliative care professionals found DT to be a valuable non-pharmacological hospital-based intervention to address the person beyond the patient and his clinical conditions. In our experience, considering that in Italy, psychotherapy is an intervention that psychotherapists can only perform, it can help organize different training on DT for psychotherapists and other healthcare professionals.

BackgroundThe global shortage and turnover of nurses is a current challenge. Past studies have shown that nurse job satisfaction may ameliorate nurse shortage. Although there are many studies on the criteria influencing nurses' job satisfaction, few have examined the causal relationships and weight of each criterion from a systematic perspective.ObjectiveIdentify the key criteria and causal relationships that affect nurses' job satisfaction, and help nurse leaders identify high-weight, high-impact dimensions and contextualize them for improvement.MethodsThe study developed a hybrid multi-criterion decision-making model, which incorporated the McCloskey/Mueller satisfaction 13-item scale (MMSS-13), and the Decision-Making Trial and Evaluation Laboratory and the Importance-Performance Analysis methods the model was used to analyze key factors of nurse satisfaction and their interrelationships based on the experience of 15 clinical nurse specialists.ResultsIn MMSS-13's dimension level, “satisfaction with work conditions and supervisor support” (C5) had the highest impact, and “satisfaction with salary and benefits” (C1) had the highest weight. In criteria level, “salary” (C11), “flexibility in scheduling time off” (C24), “maternity leave time” (C31), “opportunities for social contact after work” (C41), and “your head nurse or facility manager” (C51) had high influence under their corresponding dimensions. The “benefits package” (C13) was the top criterion with the highest impact on MMSS-13.ConclusionsThis study assessed nurses' job satisfaction from a multidimensional perspective and revealed the causal relationships between the dimensions. It refined the assessment of nurse job satisfaction to help nurse leaders better assess nurse job satisfaction and make strategic improvements. The study found that compensation and benefits had the highest weight in nurses' job satisfaction. Meanwhile, support for family responsibilities and working conditions, and support from supervisors were the cause dimensions of job satisfaction. Among the more detailed criteria, salary, benefits package, maternity leave time, and leadership had a greater impact on nurses' job satisfaction. Nurse leaders should start with these dimensions to achieve efficient improvement of nurses' job satisfaction.

PurposeTo explore the effect of human papillomavirus (HPV) status on prognosis and further investigate whether human papillomavirus (HPV) status has an impact on the local treatment strategies for T1-2N0 oropharyngeal squamous cell cancer (OPSCC) patients.MethodsPatients diagnosed with T1-2N0 OPSCC between 2010 and 2015 were included from the Surveillance, Epidemiology, and End Results database. Data were analyzed using propensity score matching (PSM), Chi-square test, Kaplan-Meier survival analysis, and Cox multivariable analyses.ResultsA total of 1,004 patients were identified, of whom 595 (59.3%) had HPV-related tumors. Of all the patients, 386 (38.4%) and 618 (61.6%) received definitive radiotherapy and radical surgery, respectively. HPV status had no significant effect on local treatment strategies for early-stage OPSCC (P = 0.817). The 3-year cancer-specific survival (CSS) and overall survival (OS) were 89.6 and 80.1%, respectively. Compared to those with HPV-negative diseases, patients with HPV-positive diseases had better CSS and OS. A total of 222 pairs of patients were completely matched after PSM. The results of multivariate Cox regression analysis showed that patients with HPV-positive disease had significantly better CSS (P = 0.001) and OS (P &lt; 0.001) compared to those with HPV-negative tumors. However, local treatment strategy was not associated with survival outcomes after PSM (CSS, P = 0.771; OS, P = 0.440). The subgroup analysis showed comparable CSS and OS between those treated with radical surgery and definitive radiotherapy regardless of HPV status.ConclusionsHPV status is an independent prognostic factor for the survival of stage T1-2N0 OPSCC patients. Local treatment strategies had no significant effect on the survival of early-stage OPSCC regardless of HPV status. Patients with early-stage OPSCC should be informed regarding the pros and cons of definitive radiotherapy or radical surgery.

ObjectivesWhile timely assessment of long-term survival for patients with cervical cancer is essential for the evaluation of early detection and screening programs for cervical cancer, those data are extremely scarce in China. We aimed to timely and accurately assess long-term survival for patients with cervical cancer in eastern China, using cancer registry data from Taizhou, eastern China.MethodsPatients diagnosed with cervical cancer during 2004–2018 from four cancer registries with high-quality data from Taizhou, eastern China were included. A period analysis was used to calculate the 5-year relative survival (RS) overall and on stratification by sex, age at diagnosis, and region. Additionally, the projected 5-year relative survival (RS) of patients with cervical cancer during 2019–2023 was evaluated, using a model-based period analysis.ResultsOverall 5-year RS for patients with cervical cancer during 2014–2018 reached 90.9%. When stratified by age at diagnosis, we found a clear age gradient for 5-year RS, declining from 95.6% for age &lt;45 years to 68.7% for age &gt;74 years, while urban areas had higher 5-year RS compared to rural areas (92.9 vs. 88.6%). We found a clear increasing trend of 5-year RS during 2004–2018 overall and on stratification by region and age at diagnosis. The projected overall 5-year RS is expected to reach 94.2% for the period 2019–2023.ConclusionsWe found that, for the first time in China, using period analysis, the most up-to-date (during 2014–2018) 5-year RS for patients with cervical cancer reached 90.9%. Our data have important implications for the timely evaluation of early detection and screening programs for patients with cervical cancer in eastern China.

Published: July 2022

The scattering by suspended particles is being measured with increasing frequency in the global oceans. Yet, little is known of size fractioned contribution, particularly from submicron particles and to the polarized scattering. In this study, three Mueller scattering matrix elements, P11, P12, and P22, for the bulk particles and for size fractions &lt;0.2 μm and &lt;0.7/0.8 μm were measured using a commercial instrument LISST-VSF in the North Pacific Ocean in 2018 (NPO-18) and in the North Atlantic Ocean in 2021 (NAO-21). We found that P11 and P12 by particles &lt;0.2 μm each had median value that was very similar between the two sites, even though the variability was greater in the NAO-21 than in the NPO-18. Relatively, particles &lt;0.2 µm accounted for the same fraction of total particle scattering in P11 and P12, approximately 20% at near surface water and 40–60% at deeper depths. In contrast, P11 and P12 by particles &lt;0.7/0.8 μm differed between the two sites, which we found was because particles of sizes 0.25–1.0 µm had greater concentration in the NAO-21 than in the NPO-18. P22 normalized to P11 indicated that the sphericity of particles was the same between submicron and bulk particles in the NPO-18 site, but bulk particles deviated more from sphericity than submicron particles in the NAO-21 site where the experiment took place during a phytoplankton spring bloom. Simulations were conducted using three particle models including homogenous spheres, mix of homogenous/coated spheres, and homogenous asymmetric hexahedra to account for the effects of particle shapes or internal structures on the polarized scattering. Using the size distribution that was measured, each of the models can reproduce some of the scattering features measured in this study, but neither of them can reproduce all. Our results suggest that accurate simulation of the polarized scattering by oceanic particles needs to account for both their nonsphericity and heterogeneity, in addition to the concentration and size distribution of the particles.
