Learning to switch gears - Steering palliative care into emergency medicine.

Emergency care is largely seen as synonymous with resuscitation and saving lives. In most of the developing world where Emergency Medicine (EM) is still evolving, the concept of EM palliative care is alien. Provision of palliative care in such settings poses its own challenges in terms of knowledge gaps, socio-cultural barriers, dismal doctor-to-patient ratio with limited time for communication with patients, and lack of established pathways to provide EM palliative care. Integrating the concept of palliative medicine is crucial for expanding the dimension of holistic, value-based, quality emergency care. However, glitches in decision-making processes, especially in high patient volume settings, may lead to inequalities in care provision, based on socio-financial disparities of patients or premature termination of challenging resuscitations. Pertinent, robust, validated screening tools and guides may assist physicians in tackling this ethical dilemma.

Clinical Determinants of Severe COVID-19 Disease - A Systematic Review and Meta-Analysis.

BACKGROUND: A systematic review and meta-analysis of available studies was performed to investigate the clinical characteristics that can predict COVID-19 disease severity. MATERIALS AND METHODS: Databases including PubMed, Embase, and Web of Science were searched from December 31, 2019, to May 24, 2020. Random-effects meta-analysis was used for summarizing the Pooled odds ratio (pOR) of individual clinical characteristics to describe their association with severe COVID-19 disease. RESULTS: A total of 3895 articles were identified, and finally, 22 studies comprising 4380 patients were included. Severe disease was more common in males than females (pOR: 1.36, 95% confidence interval [CI]: 1.08-1.70). Clinical features that were associated with significantly higher odds of severe disease were abdominal pain (pOR: 6.58, 95% CI: 1.56-27.67), breathlessness (pOR: 3.94, 95% CI: 2.55-6.07), and hemoptysis (pOR: 3.35, 95% CI: 1.05-10.74). pOR was highest for chronic obstructive pulmonary disease (pOR: 2.92, 95% CI: 1.70-5.02), followed by obesity (pOR: 2.84, 95% CI: 1.19-6.77), malignancy (pOR: 2.38, 95% CI: 1.25-4.52), diabetes (pOR: 2.29, 95% CI: 1.56-3.39), hypertension (pOR: 1.72, 95% CI: 1.23-2.42), cardiovascular disease (pOR: 1.61, 95% CI: 1.31-1.98) and chronic kidney disease (pOR: 1.46, 95% CI: 1.06-2.02), for predicting severe COVID-19. CONCLUSION: Our analysis describes the association of specific symptoms and comorbidities with severe COVID-19 disease. Knowledge of these clinical determinants will assist the clinicians in the risk-stratification of these patients for better triage and clinical management.

Prognostic Value of Serum Procalcitonin Levels in Patients With Febrile Neutropenia Presenting to the Emergency Department.

BACKGROUND: Various risk-stratification scores have been developed to identify low-risk febrile neutropenia (FN). The Multinational Association of Supportive Care in Cancer (MASCC) score is a commonly used validated scoring system, although its performance varies due to its subjectivity. Biomarkers like procalcitonin (PCT) are being used in patients with FN to detect bacteremia and additional complications. OBJECTIVE: Our objective was to compare the performance of MASCC score with PCT in predicting adverse outcomes in patients with FN. METHODS: This was a prospective observational study that included chemotherapy-induced FN in hematologic or solid malignancy. The MASCC score, PCT levels, and blood cultures were taken at the first point of contact, and patient treatment was managed according to routine institutional protocol. The primary outcome was mortality at 30 days. RESULTS: A total of 100 patients were recruited, of which 92 had hematologic malignancy and 8 had solid malignancy. Forty-six patients were classified as low risk by MASCC score (≥21). The PCT threshold, 1.42 ng/mL, was taken as a cutoff value, with area under the receiver operating characteristic curve (AUROC) of 0.664 (95% confidence interval [CI] -0.55 to 0.77) for predicting mortality. AUROC for MASCC was 0.586 (95% CI 0.462 to 0.711). CONCLUSIONS: PCT is a useful marker with better prognostic efficacy than MASCC score in patients with FN and can be used as an adjunct to the score in risk-stratifying patients with FN.

Occupational Sharp Injury and Splash Exposure among Healthcare Workers in a Tertiary Hospital.

Background Occupational hazards like sharp injury and splash exposure (SISE) are frequently encountered in health-care settings. The adoption of standard precautions by healthcare workers (HCWs) has led to significant reduction in the incidence of such injuries, still SISE continues to pose a serious threat to certain groups of HCWs. Materials and Methods This was a retrospective study which examined the available records of all patients from January 2015 to August 2019 who self-reported to our emergency department with history of sharp injury and/or splash exposure. Details of the patients, mechanism of injury, the circumstances leading to the injury, status of the source (hepatitis B surface antigen, human immunodeficiency virus, and hepatitis C virus antibody status), and the postexposure prophylaxis given were recorded and analyzed. Data were represented in frequency and percentages. Results During the defined period, a total of 834 HCWs reported with SISE, out of which 44.6% were doctors. Majority of the patients have SISE while performing medical procedures on patients (49.5%), while 19.2% were exposed during segregation of waste. The frequency of needle stick injury during cannulation, sampling, and recapping of needle were higher in emergency department than in wards. More than 80% of HCWs received hepatitis B vaccine and immunoglobulin postexposure. Conclusion There is need for periodical briefings on practices of sharp handling as well as re-emphasizing the use of personal protective equipment while performing procedures.

The INDUSEM Position Paper on the Emerging Electronic Waste Management Emergency.

Electronic waste or e-waste is a serious and concerning issue globally. Exponential increase in the production of these instrument have created a man-made problem of e-waste; United Nations has called it as "tsunami of e-waste." Informal management and unsafe disposals have compounded the problem further. The hazardous chemicals, metals, and organic pollutants released from e-waste can lead to serious health consequences such as organ damage, genetic defects, neuropsychiatric illness, and cancer. Problem of e-waste is colossal and should be seen as major public health emergency. In India, use of electronic instrument has increased considerably with less focus on formal waste management and safe disposal. This has created a major health hazard. International health agencies, Indian Council of Medical Research, e-waste regulating bodies, academic institutes, and various government and non-government organizations should join hands together to effectively manage the problems of e-waste. Swacch Bharat Abhiyan started by the honorable Prime Minster should consider e-waste as the top most priority in terms of its safe management and disposal.

Serum Angiopoietin-1 and -2 and VEGF are associated with severe disease in vivax malaria.

BACKGROUND & OBJECTIVES: Malaria continues to be a significant public health problem in tropical countries including India; however, there are limited tools to predict occurrence of severe disease due to malaria. This study was designed to evaluate the role of Angiopoietin-1 (Ang-1), Angiopoietin-2 (Ang-2), Vascular endothelial growth factor (VEGF) and Asymmetric Dimethylarginine (ADMA)as disease biomarkers in uncomplicated malaria (UM) and severe malaria (SM). METHODS: This is a prospective observational study carried out at All India Institute of Medical Sciences (AIIMS), tertiary referral hospital in New Delhi, India. The study population included patients diagnosed with malaria (Plasmodium falciparum or Plasmodium vivax) either by rapid diagnostic kit test or positive peripheral smear and age more than 12 years. Forty-nine patients (25 with SM, 24 with UM) and 22 controls were recruited. In addition to routine investigations, serum concentrations of Ang-1, Ang-2, VEGF and ADMA were measured using ELISA technique. RESULTS: We observed Ang-1 serum levels to be significantly lower in patients with severe malaria (7775 pg/ml) compared to uncomplicated malaria (17629 pg/ml) and healthy controls (43472 pg/ml) [p <0.001]. Ang-2 levels were significantly higher in severe malaria (11100 pg/ml) compared to uncomplicated malaria (7315 pg/ml) and healthy controls (3679 pg/ml) (p <0.001). The ratio of Ang-2/Ang-1 was significantly higher in patients with severe malaria. VEGF serum levels was significantly lower in severe malaria (130.36 pg/ml) compared to uncomplicated malaria (317.3 pg/ml). The Ang-1, Ang-2 and VEGF levels were able to differentiate severe malaria from uncomplicated malaria caused by P. vivax but not with P. falciparum. INTERPRETATION & CONCLUSION: We conclude that Ang-1, Ang-2 and VEGF are markers of disease severity in vivax malaria.

CISNE versus MASCC: Identifying low risk febrile neutropenic patients.

OBJECTIVE: Febrile neutropenia though a dreaded complication of chemotherapy, not all patients need inpatient treatment. Risk score indices like MASCC and CISNE have been developed to identify low risk patients eligible for outpatient management. We undertook this study to compare the performances of MASCC and CISNE. METHODS: This was a prospective observational study conducted in a tertiary care centre from August 2017 to April 2019 where patients with chemotherapy induced febrile neutropenia were included. Basic demographic data and primary site of cancer were collected with characteristics required to calculate both MASCC and CISNE scores. The primary outcome measure was 30-day mortality. Apart from the 3 group risk stratification of CISNE, apriori it was decided that two-tier CISNE score will be calculated with 0 or 1 score as low risk and ≥2 as high risk. Descriptive statistics are reported and predictive performance of each score was analysed. RESULTS: Total of 129 patients were recruited. The performance of three-tier CISNE score was more specific (90.6%, 95% CI 76.9-96.9) but sensitivity (25.1%, 95% CI 17.0-36.3) was low compared to that of MASCC score (sensitivity 58.1%, 95% CI 47.0-68.5; specificity 65.1, 95% CI 49.0-78.5%). However, analysis with two-tier CISNE score demonstrated a better sensitivity (56.9%, 95%CI 45.8-67.4). Kappa for agreement between the two scores was 0.520 (95% CI 0.373-0.667, p < 0.001). CONCLUSION: CISNE and MASCC have fair discriminatory power in identifying low risk febrile neutropenia cases. Two group stratification on CISNE scoring will help in better decision making in emergency department.

Atrial Myxoma Presenting as Acute Bilateral Limb Ischemia.

BACKGROUND: Cardiac myxoma is the most common primary benign tumor of the heart and it has diverse clinical presentations. It is known to embolize into systemic circulation. However, presentation with complete occlusion of the aorta is uncommon. CASE REPORT: We report an 18-year-old female who presented to the emergency department with features of acute bilateral limb ischemia. Arterial Doppler ultrasonography showed infrarenal aortic occlusion. A bedside cardiac ultrasound was done in the emergency department which clinched the diagnosis of atrial myxoma. Complete surgical excision of the tumor and subsequent histopathologic examination confirmed the diagnosis of atrial myxoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This report puts emphasis on the fact that atrial myxoma, though rare, may be considered as a source of embolism in patients presenting with acute limb ischemia. The importance of bedside ultrasonography for early diagnosis in such presentations is also highlighted.

Effect of probiotic fermented milk and chlorophyllin on gene expressions and genotoxicity during AFB1-induced hepatocellular carcinoma.

The aim of this study was to investigate the chemopreventive effect of probiotic fermented milk and chlorophyllin on aflatoxin B1 (AFB1) induced hepatocellular carcinoma. In vivo trials were conducted on 200 Wistar rats allocated to eight groups. Rats in the positive control group were given intraperitoneal injection of aflatoxin B1 at 450 µg/kg body weight twice a week for 6 weeks. The rats were sacrificed and dissected at 25th week of the experiment, and comet assay was carried out in hepatic cells to assess the genotoxicity or DNA damage. The tumour incidence was decreased by approximately one-third than AFB1 control group. The expression of c-myc bax, bcl-2, cyclin D1, p53 and rasp-21 genes was also studied. A significant (P<0.05) reduction in DNA damage was observed in probiotic fermented milk with chlorophyllin group as compared to aflatoxin B1 control group. The c-myc, bcl-2, cyclin D1 and rasp-21 level was found to be highest in AFB1 control group as compared to the treatment group. The results advocate the enhanced protective potential of probiotic fermented milk and chlorophyllin against AFB1-induced molecular alterations in hepatic cells during carcinogenesis.
