Potential role of telemedicine in solving ST-segment elevation dilemmas in remote areas during the COVID-19 pandemic

Delay in Regular Visits of Chronic Disease Patients and Its Associated Factors during the COVID-19 Pandemic

Background

Chronic patients need regular follow-ups. During the COVID-19 pandemic, these regular visits can be affected. The delay of chronic patients and its contributing factors in their periodic visits during the COVID-19 pandemic are examined here.

Methods

This cross-sectional study was conducted between February and June 2021, in Fars, Iran. Two hundred and eighty-six households with at least one chronic patient were recruited. Then, several trained questioners called the studied households and asked about the studied variables. The dependent variable was the number of delays in regular visits during the COVID-19 pandemic. The results were analyzed through Poisson regression by SPSS Statistics version 22 and GraphPad Prism software version 9. A significance level of 0.05 was considered for this study.

Results

Out of 286 households 113 (73.4%) fathers, 138 (70.1%) mothers, and 17 (58.6%) children in the households reported delayed referral. In fathers, referring to the health center was significantly associated with a decrease in the number of delays (P=0.033). The higher age of the householder (P=0.005), the higher number of children (P=0.043), and having a family physician (P=0.007) in the mothers' group, also the number of children in households (P=0.001) in the children group were significantly associated with increasing the number of delays.

Conclusion

COVID-19 pandemic not only creates direct harmful effects but also adversely affects people in danger of chronic diseases. Delays in follow-ups are taken into account as a major challenge during the COVID-19 pandemic. This issue is not limited to rural or urban residency.

ST-Segment Elevation Myocardial Infarction (STEMI) Management in the Era of COVID-19: A Systematic and Critical Review of Published Guidance Reports

Background

Coronavirus disease 2019 (COVID-19) had a major impact on healthcare systems worldwide. During the early phase of the pandemic many elective procedures were postponed. At the same time, the safe and effective management of medical emergencies such as ST-segment elevation myocardial infarction (STEMI) has been a challenge.

Methods

A systematic literature search was conducted aiming to identify published guidance reports by national or international societies regarding the management of patients suffering STEMI in the era of COVID-19.

Results

Among 1681 articles initially retrieved, six fulfilled the inclusion criteria and were included in the systematic review. Two reports were international consensus documents, while four reports were national guidance statements from Asian countries (Taiwan, India, Iran, and China). Most documents were drafted during the early phase of the pandemic. According to the international consensus documents, percutaneous coronary intervention (PCI) should be regarded as the reperfusion method of choice. On the other hand, in three out of four national consensus statements (Taiwan, Iran and China) fibrinolysis was considered as the reperfusion method of choice for STEMI in suspected/confirmed patients with COVID-19, unless contraindicated or in the presence of high cardiovascular risk clinical features. Authors of all documents underlined the need for early COVID-19 testing in patients with STEMI to better determine the next therapeutical steps.

Conclusions

National and international consensus statements for STEMI management in the era of COVID-19 have been published mainly during the early peak phase of the pandemic. Authors recognise that these recommendations are mainly based on expert opinions and observational data. As global immunization rates increase and methods for rapid COVID-19 detection are widely available, the implementation of traditional evidence-based practices used before the pandemic is becoming more feasible.

Is T-Wave Alternans a Repolarization Abnormality Marker in COVID-19? An Investigation on the Potentialities of Portable Electrocardiogram Device

Background

Cardiac arrhythmias are significantly associated with poor outcomes in coronavirus disease 2019 (COVID-19) patients. Microvolt T-wave alternans (TWA) can be automatically quantified and has been recognized as a representation of repolarization heterogeneity and linked to arrhythmogenesis in various cardiovascular diseases. This study aimed to explore the correlation between microvolt TWA and COVID-19 pathology.

Methods

Patients suspected of COVID-19 in Mohammad Hoesin General Hospital were consecutively evaluated using Alivecor^® Kardiamobile 6L™ portable electrocardiogram (ECG) device. Severe COVID-19 patients or those who are unable to cooperate in active ECG self-recording were excluded from the study. TWA was detected and its amplitude was quantified using the novel enhanced adaptive match filter (EAMF) method.

Results

A total of 175 patients, 114 COVID-19 patients (polymerase chain reaction (PCR)-positive group), and 61 non-COVID-19 patients (PCR-negative group) were enrolled in the study. PCR-positive group was subdivided according to the severity of COVID-19 pathology into mild and moderate severity subgroups. Baseline TWA levels were similar between both groups during admission (42.47 ± 26.52 µV vs. 44.72 ± 38.21 µV), but higher TWA levels were observed during discharge in the PCR-positive compared to the PCR-negative group (53.45 ± 34.42 µV vs. 25.15 ± 17.64 µV, P = 0.03). The correlation between PCR-positive result in COVID-19 and TWA value was significant, after adjustment of other confounding variables (R² = 0.081, P = 0.030). There was no significant difference in TWA levels between mild and moderate severity subgroups in patients with COVID-19, both during admission (44.29 ± 27.14 µV vs. 36.75 ± 24.46 µV, P = 0.34) and discharge (49.47 ± 33.62 µV vs. 61.09 ± 35.99 µV, P = 0.33).

Conclusions

Higher TWA values can be observed on follow-up ECG obtained during discharge in the PCR-positive COVID-19 patients.

Epidemiological pattern of orthopaedic fracture during the COVID-19 pandemic: A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis aimed evaluate the 30-day mortality, number and site of fracture, mechanism of injury, and location where injury was sustained during the pandemic compared to pre-pandemic.

METHODS

We performed a systematic literature search from PubMed and Embase on original articles, research letters, and short reports which have data about the number of fractures, site of fracture, mechanism of injury, location where injury was sustained, percentage of operative intervention, mortality during the pandemic compared to a specified period of time before the pandemic. The search was finalized in October 14, 2020.

RESULTS

A total of 11,936 participants from 16 studies were included in our study. The pooled analysis indicated a higher 30-days mortality associated with fractures during the pandemic (9% vs 4%, OR 1.86 [1.05, 3.27], p = 0.03; I2: 36%, p = 0.15). The number of fractures presenting to hospitals has declined 43% (35-50%) compared to pre-pandemic. Hand fracture was fewer during the pandemic (18% vs 23%, OR 0.75 [0.58, 0.97], p = 0.03; I2: 69%, p = 0.002). Work-related traumas, high-energy falls, and domestic accidents were more common during the pandemic, while sports-related traumas were found to be less. Injuries that occurred in the sports area were lower than before the pandemic.

CONCLUSION

The present meta-analysis showed that during the COVID-19 pandemic, the number of fractures has decreased, but there is a higher mortality rate associated with fractures.

Coronavirus disease 2019 (COVID-19) markedly increased mortality in patients with hip fracture - A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis aimed to evaluate the prevalence of coronavirus disease 2019 (COVID-19) and its impact on mortality in patients with hip fracture.

METHODS

We performed a systematic literature search in PubMed, Cochrane Central Database, and medRvix from inception up to July 13, 2020 on research articles that enrolled hip fracture patients who had information on COVID-19 and clinically validated definition of death.

RESULTS

A total of 984 participants from 6 studies were included in our study. The pooled prevalence of COVID-19 was 9% [95% CI: 7-11%]. The mortality rate in patients with concomitant hip fracture and COVID-19 was found to be 36% (95% CI: 26-47%), whereas the mortality rate in hip fracture without COVID-19 is 2% (95% CI: 1-3%). Meta-analysis showed that COVID-19 was associated with a seven-fold increase in risk (RR 7.45 [95% CI: 2.72, 20.43], p < 0.001; I2: 68.6%) of mortality in patients with hip fracture. Regression-based Harbord's test showed no indication of small-study effects (p = 0.06).

CONCLUSION

The present meta-analysis showed that COVID-19 increased the risk of mortality in patients with hip fracture.

The Effect of Metformin Consumption on Mortality in Hospitalized COVID-19 patients: a systematic review and meta-analysis

BACKGROUND AND AIMS

Diabetes is one of the most common comorbidities, and it is associated with poorer outcomes in patients with coronavirus disease 2019 (COVID-19). Preliminary findings showed that mortality was reduced in those who consume metformin compared to those who did not, and given its low cost and widespread availability; metformin is an attractive and potential agent to mitigate excessive risk in diabetic populations.

METHODS

Several medical databases (Pubmed, EuropePMC, EBSCOhost, Proquest, Cochrane library) and two health-science preprint servers (preprint.org and Medrxiv) were systematically searched for relevant literature.

RESULTS

Nine studies with 10,233 subjects were included in the qualitative and quantitative synthesis. Meta-analysis showed that metformin is associated with lower mortality in pooled non-adjusted model (OR 0.45 [0.25, 0.81], p = 0.008; I2: 63.9%, p = 0.026) and pooled adjusted model (OR 0.64 [0.43, 0.97], p = 0.035; I2: 52.1%, p = 0.064).

CONCLUSION

The analysis showed that metformin consumption was associated with lower mortality. Randomized controlled trials are needed to confirm this finding.

Ayurveda and Allopathic Therapeutic Strategies in Coronavirus Pandemic Treatment 2020

Purpose of Review

In the last month of 2019, i.e., December, COVID-19 hit Wuhan city in China. Since then, it has infected more than 210 countries and nearly about 33.4 million people with one million deaths globally. It is a viral disease with flu-like symptoms; hence, prevention and management is the best option to be adopted for its cure.

Recent Findings

Many healthcare systems, scientists, and researchers are fighting for the cure of this pandemic. Ayurvedic and allopathic treatments have been studied extensively and approached for the cure of COVID-19. In addition to ayurvedic treatments, the Ministry of Ayush, India, has also recommended many remedies to boost up immunity. Allopathic studies involved several antiviral drugs which were used in different combinations for the treatment of COVID-19.

Summary

Comparative analysis of Ayurveda and allopathic treatment strategies were carried out in the present study. Depending upon the patient's conditions and symptoms, Ayurveda is useful for the treatment of COVID-19. Allopathic treatments inhibit viral infection by targeting majorly endocytosis, and angiotensin-converting enzyme (Ace) receptor signaling. In this article, we summarize different ayurvedic and allopathic medicines and treatment strategies which have been used for the treatment of COVID-19, a global pandemic.
