To date, the COVID-19 pandemic has caused millions of deaths across the world. Prognostic scores can improve the clinical management of COVID-19 diagnosis and treatment. The objective of this study was to assess the predictive role of 4C Mortality, CURB-65, and NEWS in COVID-19 mortality among the Romanian population. A single-center, retrospective, observational study was conducted on patients with reverse transcriptase-polymerase chain reaction (RT-PCR)-proven COVID-19 admitted to the Municipal Emergency Clinical Hospital of Timisoara, Romania, between 1 October 2020 and 15 March 2021. Receiver operating characteristic (ROC) and area under the curve (AUC) analyses were performed to determine the discrimination accuracy of the three scores. The mean values of the risk scores were higher in the non-survivors group (survivors group vs. non-survivors group: 8 vs. 15 (4C Mortality Score); 3 vs. 8.5 (NEWS); 1 vs. 3 (CURB-65)). In terms of mortality risk prediction, the NEWS performed best, with an AUC of 0.86, and the CURB-65 score performed poorly, with an AUC of 0.80. CURB-65, NEWS, and 4C Mortality scores were significant mortality predictors in the analysis, with acceptable calibration. Among the scores assessed in our study, NEWS had the highest performance in predicting in-hospital mortality in COVID-19 patients. Thus, the findings from this study suggest that the use of NEWS may be beneficial to the early identification of high-risk COVID-19 patients and the provision of more aggressive care to reduce mortality associated with COVID-19.
During the COVID-19 pandemic, it was observed that patients with heart disease are more likely to be hospitalized and develop severe COVID-19. Cardiac disease takes the top position among patient comorbidities, heart failure (HF) prevalence reaching almost 5% in the general population older than 35 years in Romania. This retrospective study aimed to determine the potential use of the NYHA classification for HF in hospitalized patients with COVID-19 as prognostic tool for in-hospital mortality, length of hospitalization, and probability of rehospitalization for HF decompensation. We observed that patients with advanced HF had a history of significantly more comorbid conditions that are associated with worse disease outcomes than the rest of patients classified as NYHA I and II. However, regardless of existing diseases, NYHA III, and, especially, NYHA IV, patients were at greatest risk for mortality following SARS-CoV-2 infection. They required significantly longer durations of hospitalization, ICU admission for mechanical ventilation, and developed multiple severe complications. NYHA IV patients required a median duration of 20 days of hospitalization, and their in-hospital mortality was as high as 47.8%. Cardiac biomarkers were significantly altered in patients with SARS-CoV-2 and advanced HF. Although the study sample was small, all patients with NYHA IV who recovered from COVID-19 required a rehospitalization in the following month, and 65.2% of the patients at initial presentation died during the next six months. The most significant risk factor for mortality was the development of severe in-hospital complications (OR = 4.38), while ICU admission was the strongest predictor for rehospitalization (OR = 5.19). Our result highlights that HF patients continue to be vulnerable post SARS-CoV-2 infection. Physicians and policymakers should consider this population’s high likelihood of hospital readmissions when making discharge, hospital capacity planning, and post-discharge patient monitoring choices.
Objectives Small cell carcinoma (SCC) of the pancreas is a rare malignancy with a poor prognosis. We established and characterized a primary human pancreatic SCC cell line, designated A99. Methods Cancer tissue was obtained from the liver metastasis of a SCC of the pancreas and xenografted into nude mice. The first-pass xenograft was then used to establish a cultured cell line called A99. Cellular morphology, immunohistochemical properties, tumorigenic potential, and genetic alterations of this new line were characterized. Results A99 cells grew consistently in culture, formed colonies in soft agar and grew as subcutaneous xenografts when inoculated into nude mice. A99 cells were positive for pancytokeratin, synaptophysin, chromogranin A, NSE, CD57 (Leu7), CD56, PGP 9.5, TTF-1, Smad4, p53 and p16 but not for CD99, PDX-1 or RB protein. Sequencing analysis revealed homozygous point mutations of KRAS and TP53. Cytogenetic analysis revealed complex chromosomal rearrangements including marker chromosomes. Conclusions A99 is the first cell line report to be derived from a primary SCC of the pancreas. The establishment of this cell line may serve as a useful model system for studying the cell biology of this rare cancer, or for evaluation of novel targeted agents in preclinical models.
Purpose The year 2020 was marked by the COVID-19 pandemic, massively disruptive at the general population level and for healthcare systems. We aimed to evaluate the psychological distress associated with work-related experiences among medical professionals and supporting staff during the pandemic outbreak. Patients and Methods A cross-sectional survey was conducted between April and May 2020, employing a self-administered on-line questionnaire that included the collection of socio-demographic and professional status information, Hamilton Anxiety Rating Scale, nine-item Patient Health Questionnaire (PHQ-9), Maslach Burnout Inventory - General Survey, Connor-Davidson Resilience Scale, and a subscale of the International Personality Item Pool (IPIP) for empathy. A total of 364 professionals of the county-coordinated area responded. Descriptive statistics summarized the findings and a mediation model was analyzed, applying the causal step strategy. The specific direct and causal mediation effects were estimated with the bias-corrected and accelerated bootstrap sampling method. Results Anxiety, burnout, stress, resilience, and empathy proved to be significantly associated with both the professional category (ie, consultant, specialty doctor, trainee doctor, senior nurse, trainee nurse or other) and the perceived professional support (the nonparametric multivariate permutation test resulted in p=0.048 and p<0.001, respectively). When controlling for the marital and professional status, the female gender had an OR=2.26, 95% CI (1.21; 4.22) toward a high level of empathy compared to males. The causal mediation effect of the perceived lack of professional support on empathy through burnout-depersonalization was highly significant (p<0.001) with an average of 0.0599, 95% CI (0.0238; 0.10), while the direct effect was non-significant (p=0.536) with an average of 0.0295, 95% CI (−0.0774; 0.15). Conclusion We highlighted the impact of the lack of professional support on healthcare workers’ empathy through burnout-depersonalization in a context of a high workload, time pressure, job stress beyond previous training, and inherently limited organizational support, which are potentially modifiable factors in the mid-term.
The aim of the present study was to determine the pattern of symptoms of ragweed pollen-induced allergic disease in sensitized patients from Romania and to compare the molecular diagnosis of allergy with the skin prick test, in order to better characterize allergic patients and to guide therapy. A total of 97 subjects, including patients with ragweed pollen-induced allergic rhinoconjunctivitis with/without asthma, as well as healthy controls, were recruited prospectively in one ragweed pollen season, submitted to allergy questionnaires, skin prick tests and multiplex specific IgE (immunoglobulin E) measurement by ImmunoCAP ISAC (ImmunoCAP Immuno-Solid phase Allergy Chip) assay. A total of 83 patients were sensitized to ragweed pollen. Most patients (73%) were diagnosed with moderate-severe intermittent allergic rhinoconjunctivitis and 25% of the patients also had allergic asthma. The most common symptoms were watery rhinorrhea (91.57%), nasal obstruction (86.75%), and sneezing (85.54%). Most patients were polysensitized (62.65%), especially to other pollens, house dust mites and animal danders. Only 90% of the patients with positive skin prick test to ragweed pollen extract also had increased specific serum IgE to Amb a 1. Current options for specific molecular diagnosis of ragweed allergy are limited, as they only contain one or few of the sensitizing allergens present in ragweed pollen. An improved component-resolved diagnosis, using several ragweed pollen allergens, is required for better patient characterization and subsequent selection of an appropriate allergen immunotherapy product, thereby enabling a more personalized approach to the management of the ragweed-allergic patient.
