ReviewHealth Systems Approach to Ensure Quality and Safety Amid COVID-19 Pandemic in Pakistan.
Ensuring quality and safe care during the coronavirus disease 2019 (COVID-19) pandemic offers a challenge to already strained health systems in low and middle-income countries (LMICs), such as Pakistan with less shock-absorbing capacities. There is a dearth of evidence on mechanisms to provide optimum quality care to COVID-19 patients in the resource-constrained healthcare environment. ⋯ Research evidence is needed to be better prepared for an effective and coordinated health systems response to offer quality and safe care to patients. Key Words: Health systems approach, COVID-19 pandemic, Quality of healthcare, Safe care.

Approximately 1% of the world population has now been infected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). With cases still rising and vaccines just beginning to rollout, we are still several months away from seeing reductions in daily case numbers, hospitalisations, and mortality. Therefore, there is a still an urgent need to control the disease spread by repurposing existing therapeutics. Owing to antiviral, anti-inflammatory, immunomodulatory, and cardioprotective actions, statin therapy has been considered as a plausible approach to improve COVID-19 outcomes. ⋯ These findings call attention to the need for systematic clinical studies to assess both pre- and in-hospital use of statins as a potential means of reducing COVID-19 disease severity, particularly in terms of reduction of ICU admission and total mortality reduction.

Comparative StudyComparison of HRCT Chest and RT-PCR in Diagnosis of COVID-19.
To compare the diagnostic accuracies of HRCT chest and RT-PCR results in diagnosis of coronavirus disease (COVID-19) in a tertiary care hospital in Lahore. ⋯ The sensitivity of HRCT chest is higher (92%) as compared to first RT-PCR (45%). Key Words: COVID-19, RT-PCR, HRCT chest, Sensitivity, Specificity.

ABSTARCT Four hundred and fifty-three SARS CoV-2 antibodies tests were conducted using Roche Elecsys® Anti SARS CoV-2 kits (detecting total antibodies) between June 13 to July 8, 2020 (25 days) on Cobas® e411 automatic analyser, based on electrochemiluminescence immunoassay (ECLIA) principle. Samples were collected from walk-in patients at our facility. Among them, 2 (0.4%) were found equivocal, 289 (63.8%) were found reactive, while 162 (35.8%) were found non-reactive. ⋯ Most common symptom was fever, found in 262 (87.9%) individuals, followed by dry cough 146 (49.0%). Most number of reactive cases, i.e. 110 (42.6%) were those who got themselves tested between 15-21 days after onset of first symptom. Key Words: COVID-19, Coronavirus, Antibodies testing.

ReviewStructural and functional insights into non-structural proteins of coronaviruses.
Coronaviruses (CoVs) are causing a number of human and animal diseases because of their zoonotic nature such as Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19). These viruses can infect respiratory, gastrointestinal, hepatic and central nervous systems of human, livestock, birds, bat, mouse, and many wild animals. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly emerging respiratory virus and is causing CoVID-19 with high morbidity and considerable mortality. ⋯ Coronavirus replicase has more or less universal activities, such as RNA polymerase (nsp 12) and helicase (nsp 13), as well as a variety of unusual or even special mRNA capping (nsp 14, nsp 16) and fidelity regulation (nsp 14) domains. Besides that, several smaller subunits (nsp 7- nsp 10) serve as essential cofactors for these enzymes and contribute to the emerging "nsp interactome." In spite of the significant progress in studying coronaviruses structural and functional properties, there is an urgent need to understand the coronaviruses evolutionary success that will be helpful to develop enhanced control strategies. Therefore, it is crucial to understand the structure, function, and interactions of coronaviruses RNA synthesizing machinery and their replication strategies.
