Performance of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 (CURB-65) score among patients with COVID-19 pneumonia in an emergency department triage setting: a retrospective study

ABSTRACT BACKGROUND: Healthcare institutions are confronted with large numbers of patient admissions during large-scale or long-term public health emergencies like pandemics. Appropriate and effective triage is needed for effective resource use. OBJECTIVES: To evaluate the effectiveness of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 years (CURB-65) score in an emergency department (ED) triage setting. DESIGN AND SETTING: Retrospective study in the ED of a tertiary-care university hospital in Düzce, Turkey. METHODS: PMEWS, STSS and CURB-65 scores of patients diagnosed with COVID-19 pneumonia were calculated. Thirty-day mortality, intensive care unit (ICU) admission, mechanical ventilation (MV) need and outcomes were recorded. The predictive accuracy of the scores was assessed using receiver operating characteristic curve analysis. RESULTS: One hundred patients with COVID-19 pneumonia were included. The 30-day mortality was 6%. PMEWS, STSS and CURB-65 showed high performance for predicting 30-day mortality (area under the curve: 0.968, 0.962 and 0.942, respectively). Age > 65 years, respiratory rate > 20/minute, oxygen saturation (SpO2) < 90% and ED length of stay > 4 hours showed associations with 30-day mortality (P < 0.05). CONCLUSIONS: CURB-65, STSS and PMEWS scores are useful for predicting mortality, ICU admission and MV need among patients diagnosed with COVID-19 pneumonia. Advanced age, increased respiratory rate, low SpO2 and prolonged ED length of stay may increase mortality. Further studies are needed for developing the triage scoring systems, to ensure effective long-term use of healthcare service capacity during pandemics.

Chemotherapy in adult soft tissue sarcoma.

Soft tissue sarcomas (STSs) are rare and histologically diverse neoplasms. Recent results of various meta-analyses and development of newer drugs have changed the medical management of soft tissue sarcoma. This review gives an outline of chemotherapy and the newer targeted therapies for the same. We have carried out an extensive search in PubMed, Medline for almost all relevant articles concerning chemotherapy of soft tissue sarcoma. The available data from the literature is mainly composed of the most recent reviews, meta-analyses, phase II, and randomized phase III trials published in various peer reviewed journals and various international conferences. The role of neoadjuvant and adjuvant chemotherapy has been found to be controversial. The recent meta-analysis for adjuvant therapy in STSs has shown an increase in the overall survival with combination of ifosfamide and adriamycin. In locally advanced and metastatic STSs, single agent adriamycin remains the basic standard of medication. The combination of ifosfamide and adriamycin may also be used for rapid symptom relief and in patients planned for curative resection for metastases. Newer combinations of docetaxel and gemcitabine appear promising in selected subgroups, especially in leiomyosarcoma and malignant fibrous histiocytoma. Some recent developments include the European Union's approval of trabectedin for advanced STSs patients who had progressed on adriamycin and ifosfamide therapy. The future of mTOR inhibitors, insulin like growth factor receptor inhibitors and anti-angiogenic drugs appear quite promising. Newer methodologies such as, Bayesian adaptive randomization and inclusion of newer end points like progression-free rate, time of progression rate, and tumor growth rate will improve the results of sarcoma trials. At the end of each section we have also presented recommendations from *European Society of Medical Oncology and **National Comprehensive Cancer Network guidelines v.1.2009 for better correlation with the present literature.
