Abstract Background New management, risk stratification and treatment strategies have become available over the last years for patients with acute pulmonary embolism (PE), potentially leading to changes in clinical practice and improvement of patients’ outcome. Methods The COntemporary management of Pulmonary Embolism (COPE) is a prospective, non-interventional, multicentre study in patients with acute PE evaluated at internal medicine, cardiology and emergency departments in Italy. The aim of the COPE study is to assess contemporary management strategies in patients with acute, symptomatic, objectively confirmed PE concerning diagnosis, risk stratification, hospitalization and treatment and to assess rates and predictors of in-hospital and 30-day mortality. The composite of death (either overall or PE-related) or clinical deterioration at 30 days from the diagnosis of PE, major bleeding occurring in hospital and up to 30 days from the diagnosis of PE and adherence to guidelines of the European Society of Cardiology (ESC) are secondary study outcomes. Participation in controlled trials on the management of acute PE is the only exclusion criteria. Expecting a 10–15%, 3% and 0.5% incidence of death for patients with high, intermediate or low-risk PE, respectively, it is estimated that 400 patients with high, 2100 patients with intermediate and 2500 with low-risk PE should be included in the study. This will allow to have about 100 deaths in study patients and will empower assessment of independent predictors of death. Conclusions COPE will provide contemporary data on in-hospital and 30-day mortality of patients with documented PE as well as information on guidelines adherence and its impact on clinical outcomes. Trail registration NCT number: NCT03631810.

Pregnancy and parturition involve extensive changes in the maternal immune system. In our randomized, multi-site, double-blind superiority trial using a Bayesian adaptive design, we demonstrated that 1000 mg/day of docosahexaenoic acid (DHA) was superior to 200 mg/day in preventing both early preterm birth (less than 34 weeks’ gestation) and preterm birth (less than 37 weeks’ gestation). The goal of this secondary study is to compare the effects of 1000 mg/day versus 200 mg/day on maternal inflammation, a possible mechanism by which DHA may prevent preterm birth. Maternal blood samples were collected at enrollment (12–20 weeks’ gestation) and at delivery. Red blood cell DHA levels were measured by gas chromatography, and plasma concentrations of sRAGE, IL-6, IL-1β, TNFα, and INFγ were measured by ELISA. Data were analyzed for associations with the DHA dose, gestational age at birth, and preterm birth (<37 weeks). Higher baseline and lower delivery levels of maternal sRAGE were associated with a greater probability of longer gestation and delivery at term gestation. Higher-dose DHA supplementation increased the probability of a smaller decrease in delivery sRAGE levels. Higher IL-6 concentrations at delivery were associated with the probability of delivering after 37 weeks, and higher-dose DHA supplementation increased the probability of greater increases in IL-6 concentrations between enrollment and delivery. These data provide a proposed mechanistic explanation of how a higher dose of DHA during pregnancy provides immunomodulatory regulation in the initiation of parturition by influencing sRAGE and IL-6 levels, which may explain its ability to reduce the risk of preterm birth.

History has shown that the “songket” is in a class of its own in the socio-culture of Malays in the Malay Archipelago. Fundamentally, “songket” and its wearing have been the symbol of acceptance and the collective instillation of cultural values. The textile was created based on cross- and multi-cultural elements that have long been established and further assimilated into society today. Therefore, this study aims to trace the beginnings and roles of the royal institutions in spreading this heritage art between Malaysia and Indonesia, specifically for “songket” Terengganu and Riau. The research focuses on the similarities based on acculturation and assimilation of culture. This study is critical as a form of knowledge documentation for both countries, which share similar connections and homogenous values. The research employs the qualitative approach, with a focus on observation and conducting interviews. A secondary study is also conducted to analyse the historical and socio-cultural aspects involved. Interview subjects from both countries were chosen based on specific fields and locations. Each finding leads and adds to the existing body of knowledge. Since issues on the Malay World usually take on a broader outlook, the implications of the study can contribute to the ethnic group itself, especially the scholars, weavers, cultural activists, art historians and the community at large. Based on the quality and uniqueness of the “songket”, there is no doubt that the textile should be acknowledged as one of the greatest heritage art, saturated with civil values and symbols of the finesse of the Malays.

Objectives: Left ventricular (LV) involvement has been associated with unfavorable prognosis in arrhythmogenic cardiomyopathy (ACM). We aim to evaluate LV mechanics by cardiovascular magnetic resonance-feature tracking (CMR-FT) in ACM patients with right ventricular (RV) dysfunction.Methods: We retrospectively recruited ACM patients diagnosed according to the revised Task Force Criteria (rTFC) from January 2015 to July 2017. All patients underwent CMR examinations and collections of clinical, electrocardiographic data. The strain and dyssynchrony parameters of LV and RV were analyzed. These patients were followed, and primary study outcome was defined as a composite of cardiovascular events (arrhythmic events and heart transplantation), secondary study outcome included arrhythmic events.Results: Eighty-nine ACM patients (40.40 ± 13.98 years, 67.42% male) were included. LV and RV ejection fractions were 49.12 ± 12.02% and 22.28 ± 10.11%, respectively. During a median (IQR) follow-up for 18.20 (11.60-30.04) months, 30 patients experienced cardiovascular events which included 22 patients who experienced arrhythmic events. Patients with cardiovascular events had impaired LV global longitudinal strain (−10.82 ± 2.77 vs. −12.61 ± 3.18%, p = 0.010), impaired LV global circumferential strain (−11.81 ± 2.40 vs. −13.04 ± 2.83%, p = 0.044), and greater LV longitudinal dyssynchrony (LVLD) (80.98 ± 30.98 vs. 64.23 ± 25.51 ms, p = 0.012) than those without. After adjusting for age, sex, and other confounding factors, LVLD ≥89.15 ms was an independent risk factor for cardiovascular events (HR: 4.50, 95% CI: 1.94 to 10.42; p = 0.001) and for arrhythmic events (HR: 4.79, 95% CI: 1.74 to 13.20; p = 0.003).Conclusions: LVLD by CMR-FT was an independent risk factor for cardiovascular and arrhythmic events in ACM patients in advanced stage, which could provide prognostic value for this subtype.

Conduct a reanalysis of transcriptome data for studying intracellular signaling or solving other experimental problems is becoming increasingly popular. Gene expression data are archived as microarray or RNA-seq datasets mainly in two public databases: Gene Expression Omnibus (GEO) and ArrayExpress (AE). These databases were not initially intended to systematically search datasets, making it challenging to conduct a secondary study. Therefore, we have created the ARGEOS service, which has the following advantages that facilitate the search: (1) Users can simultaneously send several requests that are supposed to be used for systematic searches, and it is possible to correct the requests; (2) advanced analysis of information about the dataset is available. The service collects detailed protocols, information on the number of datasets, analyzes the availability of raw data, and provides other reference information. All this contributes to both rapid data analysis with the search for the most relevant datasets and to the systematic search with detailed analysis of the information of the datasets. The efficiency of the service is shown in the example of analyzing transcriptome data of activated (polarized) cells. We have performed a systematic search of studies of cell polarization (when cells are exposed to different immune stimuli). The web interface for ARGEOS is user-friendly and straightforward. It can be used by a person who is not familiar with database searching.

Abstract Background The modifications to the standard intensive care unit (ICU) organization that had to be urgently implemented worldwide to overcome the surge of ICU admissions due to patients with a severe coronavirus disease 2019 (COVID-19) have resulted in increased workload and patients-to-nurse ratio. The aim of this study was to investigate whether level of critical care staffing could be associated with an increased risk of ICU mortality (primary endpoint), length of stay, mechanical ventilation and the evolution of disease (secondary study endpoints) in critically ill patients with COVID-19. Methods Retrospective multicenter analysis of the international Risk Stratification in COVID-19 patients in the Intensive Care Unit (RISC-19-ICU) registry that prospectively enrolls patients developing critical illness due to COVID-19 in several countries worldwide. The analysis was limited to the period between March 1st, 2020 and May 31st, 2020, to ICUs in Switzerland that have collected additional data on nurse and physician staffing. Hierarchical regression models were used to investigate crude and adjusted effects of critical care staffing ratio on study endpoints. We adjusted for diseases severity and weekly caseload. Results Among the 38 Swiss participating ICUs, 17 recorded critical care staffing information. The study population included 437 patients and 2342 daily assessments of patient-to-nurse/physician ratio. Median of daily patient-to-nurse ratio started at 1.0 ([IQR] 0.5–1.5; calendar week 9) and peaked at 2.4 (IQR 0.4-2.0; calendar week 16), while the median of daily patient-to-physician ratio started at 4.0 (IQR 2.1-5.0; calendar week 9) and peaked at 6.8 (IQR 6.3–7.3; calendar week 19). Neither the patient-to-nurse ratio [adjusted Odds Ratio (OR) 1.28, 95% confidence interval (CI) 0.85–1.94; doubling of ratio] nor the patient-to-physician ratio [adjusted OR 1.08, 95% CI 0.87–1.32; doubling of ratio] was associated with ICU mortality. We found no association of critical care staffing on the investigated secondary study endpoints in adjusted models. COnclusion The Swiss health care system successfully overcame the first wave of the COVID-19 pandemic with regards to the unprecedented demand for ICU treatments. The reduced availability of critical care staffing resources per critically ill patient in Swiss ICUs did not translate in an overall increased risk of mortality.

Crop diversification is a planned innovative approach to maximize land usage with optimum crop production to aim at minimizes losses of seasonal and other impacts on crop. India being one of the biggest countries of agricultural economy and West Bengal, although tiny in size, is one of the biggest producers of few agricultural produces like rice, potato, oil seed etc. Within West Bengal, undivided retained a significant role in agricultural produce. After division of the district in to &amp; during 2000, most of the cultivable land is within . has some pocket areas that has good reputation of cultivation. The Crop diversification is the need for the hour for small cultivable area. In this particular scenario, this study has tried to focus on the state of crop diversification in the district with a comparative study on district because of its history of its erstwhile geographical tie up. At the same time, it has also attempted to find out the effect of crop diversification on crop production. In this particular aspect this study has focused on the condition of this particular aspect on undivided district also. It has found that crop diversification on the basis of principal food crop in district has significantly positive relationship with production but has insignificant negative relationship in between crop diversity of rice with its production. In undivided there has been positive relationship between crop diversity and crop production in both principal food crops and rice. This has attracted to conclusive remark that division of district has impaired the scope of crop diversification of district but it has sufficient space to improve it as the relationship has indicated positive direction to that end although negative direction in rice crop would be matter further research.

Background. Anti-inflammatory therapy is used to achieve and maintain asthma control, as well as respiratory function indicators monitoring. Telemedicine technologies can be used for this purpose, and it became particularly essential during the COVID-19 pandemic.Objective. The aim of the study is to analyze efficacy of the mobile technology MedQuizBot for asthma monitoring, to estimate patient compliance to use such instruments of self-control via the bot and without it, and bot's functioning satisfaction.Methods. 6-month prospective observational comparative study in patients with asthma from 4 to 17 years old was conducted. All patients were divided into two groups: patients who have used MedQuizBot and patients who have used any other self-control tools. Patients had to enter peakflowmetry data daily and undergo asthma control tests monthly. Patients were able to communicate with their doctor remotely via the chat bot. Main study indicators: determining the efficacy of MedQuizBot in patients with asthma by estimating the compliance to self-control tools at using the bot. Secondary study indicators: estimation of patients satisfaction on using the MedQuizBot and determination of level of asthma control due to the obtained data results.Results. 41 patients have used MedQuizBot, 27 patients were in the control group. Patients who used the bot more often answered asthma control test questions. Patients over 12 years old have completed the asthma control test less often than young children: ACT was filled on average in 1.5 times, САСТ — 1.8 times. 51% of patients filled in data on peakflowmetry via the new technology, patients from control group did not start the picflowmetry diary. Patients under 12 years old, who filled up the test with their parents, has entered picflowmetry data 7 times more often than adolescents. The asthma was under control in 70% of patients. The data was entered into the system 2.5 times more often during the lockdown period due to COVID-19 pandemic and during the tree flowering season in comparison to other periods of2020. Patients noted the usability of the MedQuizBot and agreed to use it in future.Conclusion. MedQuizBot is effective in achieving asthma control mainly during the period of need — in case of insufficient control over the disease itself (exposure to pollen allergens, acute respiratory diseases), during the limitations in medical care availability.

Abstract Background To investigate the efficacy and safety of dexamethasone-lipiodol emulsion in the prevention of post-embolization syndrome after TACE. Method The data of 255 patients who underwent TACE in the interventional department from June 2017 to June 2020 were collected. This is a retrospective assessment of patients who were non-randomly treated with dexamethasone in TACE. The patients were divided into two groups: TACE using lipiodol + chemotherapeutic emulsion group (TACE group, N = 133); TACE using lipiodol + dexamethasone + chemotherapeutic emulsion group (TACE + dexamethasone group, N = 122). Primary study endpoint: incidence of abdominal pain, fever, nausea and vomiting 0–72 h after TACE in both groups. Secondary study endpoints: incidence of infection after TACE in both groups. Results Incidence of post-embolization syndrome after TACE (TACE group vs TACE + dexamethasone group): abdominal pain, 55.6% versus 36.1% (P value 0.002); fever, 37.6% versus 13.1% (P value 0.000); nausea, 60.9% versus 41.0% (P value 0.001); vomiting, 48.1% versus 21.3% (P value 0.000). Incidence of infection after TACE (TACE group vs TACE + dexamethasone group): 1.5% versus 2.5% (P value 0.583). Conclusion The lipiodol + dexamethasone emulsion can significantly reduce the incidence rate of post-embolization syndrome after TACE, with exact effect and high safety.
