We report that HCW share similar clinical characteristics of COVID-19 infection as those of non HCW patients in earlier studies. The infection can spread rapidly within healthcare settings via close contacts among infected HCWs. As such, we advocate distancing when working and usage of personal protective equipment when treating patients with respiratory illness to reduce transmission of COVID-19.

Spontaneous subarachnoid haemorrhage (SAH) is a significant cause of stroke and associated with high morbidity and mortality. One substantial complication of SAH is cerebral vasospasm (CV) and delayed cerebral ischemia (DCI). This study aimed to define the clinical profile in patients with SAH, CV and DCI secondary to spontaneous SAH (aneurysmal and pretruncal non-aneurysmal).

We analysed 122 consecutive patients with spontaneous SAH following intracranial aneurysmal and non-aneurysmal information (including patients' pattern characterisation and their possible risk factor association to pre-operative clinical decision and long-term clinical outcome) was documented and analysed.

The main clinical presentations for spontaneous SAH following ruptured intracranial aneurysm and nonaneurysm were headache (77%) and nausea/vomiting (62.3%). The most common sites for SAH following ruptured intracranial aneurysm rupture were the anterior and posterior communicating arteries (57.5%). Hypertension was the most comd non-aneurysmal rupture and it is associated with substantial morbidity. Prevention, effective monitoring, and early detection are keys to successful management. Regional investigation using a multicentre cohort to analyse mortality and survival rates may aid in improving national resource management of these patients.

Thrombolytic therapy with intravenous alteplase is a well-established treatment for acute ischaemic stroke (AIS). However, in Malaysia, treatment prescription is often limited by the availability of neurologists. The objective was to compare the outcomes of acute stroke thrombolysis therapy prescribed by neurologists in the Seberang Jaya Hospital (SJH) and non-neurologists in the Taiping Hospital (TH).

In this cross-sectional study, all AIS patients who received thrombolytic therapy in SJH and TH between January 2012 and September 2019 were included. Clinical data was extracted from admission records. The outcomes assessed were the percentage of patients who achieved excellent functional outcome at 3 months (modified Rankin scale of 0 to 1), rates of symptomatic intracranial haemorrhage (SICH), and mortality.

A total of 63 AIS patients who received thrombolytic therapy were included, of which 37 patients (58.7%) were treated in SJH. The median NIHSS on admission was 12 in SJH and 11.5 in TH. In all 21.6% of patients from SJH and 30.7% of patients from TH achieved favourable functional outcome at 3 months (p=0.412). There were no significant differences between the two centres in terms of the rates of SICH (10.8% in SJH and 3.8% in TH, p=0.314) and 3-month mortality (24.3% versus 12.5%, p=0.203).

The 3-month functional outcomes and complication rates of stroke thrombolysis in hospitals with or without neurologists are not significantly different. Thus non-neurologist hospitals may be able to provide thrombolysis service to AIS patients safely and effectively.

By the 20 January 2021, the cumulative numbers reported confirmed cases of COVID-19 had reached 169,379 including 630 deaths. Malaysia has been hit by three waves of COVID-19. This article reports on the three waves, the current situation and some of the possible factors associated. It outlines the need to reassess the overall situation, re-strategize the approach in order to contain the spread. The first COVID-19 wave lasted from 25 January to 16 February 2020, the second wave occurred between the 27 February 2020 and the 30 June 2020. The current third wave began on 8th September 2020.The sudden surge of cases in the third wave was mainly due to the two largest contributors, namely the Benteng Lahad Datu cluster in Sabah state and Kedah's Tembok cluster. The current situation is critical. The daily confirmed cases of COVID-19 continue to soar. The challengers faced by healthcare workers and other front liners is tremendous. Non-communicable diseases such as cardiovascular diseases, diabetes and cancer are the leading cause of death in Malaysia. A paradigm shift in the approach is required to ensure the sustainability of the normal healthcare services provided by the government especially for the lower income groups. There is also a need to expedite the tabling of Tobacco Control Bill in coming parliament session which is long overdue. H.E. the King of Malaysia has called on all Malaysians to put aside political, racial and religious differences and show the spirit of loyalty, humanitarianism and steadfastness in fighting the COVID-19 pandemic.[This corrects the article DOI 10.4103/1673-5374.286977.Animal studies have shown that amphoteric detergent and nuclease (DNase I and ribonuclease A) is the most reliable decellularization method of the peripheral nerve. However, the optimal combination of chemical reagents for decellularization of human nerve allograft needs further investigation. To find the optimal protocol to remove the immunogenic cellular components of the nerve tissue and preserve the basal lamina and extracellular matrix and whether the optimal protocol can be applied to larger-diameter human peripheral nerves, in this study, we decellularized the median and sural nerves from the cadavers with two different methods nonionic and anionic detergents (Triton X-100 and sodium deoxycholate) and amphoteric detergent and nuclease (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS), deoxyribonuclease I, and ribonuclease A). All cellular components were successfully removed from the median and sural nerves by amphoteric detergent and nuclease. Not all cellular components were removed review.Vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) are well-known growth factors involved in the regeneration of various tissues and organs, including peripheral nerve system. In the present study, we elucidated the local and systemic effects of plasmid construct рBud-coVEGF165-coFGF2 injected into the epineurium of intact rat sciatic nerve. Results of histological examination of sciatic nerve and multiplex immunoassays of serum showed the absence of immunogenicity and biosafety of plasmid рBud-coVEGF165-coFGF2. Moreover, local administration of plasmid DNA construct resulted in significantly decreased levels of pro-inflammatory cytokines in the peripheral blood, including tumor necrosis factor α (TNFα) and interleukin-12, and significantly increased levels of cytokines and chemokines including Regulated upon Activation, Normal T Cell Expressed and Presumably Secrete (RANTES), epidermal growth factor, interleukin-2, and monocyte chemoattractant protein 1. These changes in the peripheral blood on day 7 after injection of plasmid construct рBud-coVEGF165-coFGF2 show that the plasmid construct has systemic effects and may modulate immune response. At the same time, reverse transcription-polymerase chain reaction revealed transient expression of coFGF2, coVEGF165, ratFGF2 and ratVEGFA with direct transport of transcripts from distal part to proximal part of the sciatic nerve. Immunohistochemical staining revealed prolonged presence of VEGFA in sciatic nerve till 14 days post-injection. These findings suggest that local administration of plasmid construct рBud-coVEGF165-coFGF2 at a concentration of 30 ng/µL results in the formation of pro-angiogenic stimuli and, and the plasmid construct, used as a drug for gene therapy, might potentially facilitate regeneration of the sciatic nerve.

To validate this hypothesis, we established a newborn mouse model of oxygen-induced retinopathy by feeding in an oxygen concentration of 75 ± 2% from postnatal day 8 to postnatal day 12, followed by in normal air. On postnatal day 11, the mice were injected with the myocardial infarction-associated transcript siRNA plasmid via the vitreous cavity to knockdown long non-coding RNA myocardial infarction-associated transcript. Myocardial infarction-associated transcript siRNA transcription significantly inhibited myocardial infarction-associated transcript mRNA expression, reduced the phosphatidylinosital-3-kinase, phosphorylated Akt and vascular endothelial growth factor immunopositivities, protein and mRNA expression, and alleviated the pathological damage to the retina of oxygen-induced retinopathy mouse models. These findings suggest that myocardial infarction-associated transcript is likely involved in the retinal neovascularization in retinopathy of prematurity and that inhibition of myocardial infarction-associated transcript can downregulate phosphatidylinosital-3-kinase, phosphorylated Akt and vascular endothelial growth factor expression levels and inhibit neovascularization. This study was approved by the Animal Ethics Committee of Shengjing Hospital of China Medical University, China (approval No. 2016PS074K) on February 25, 2016.The physiological characteristics of the marmoset second visual area (V2) are poorly understood compared with those of the primary visual area (V1). In this study, we observed the physiological response characteristics of V2 neurons in four healthy adult marmosets using intracortical tungsten microelectrodes. We recorded 110 neurons in area V2, with receptive fields located between 8° and 15° eccentricity. Most (88.2%) of these neurons were orientation selective, with half-bandwidths typically ranging between 10° and 30°. A significant proportion of neurons (28.2%) with direction selectivity had a direction index greater than 0.5. The vast majority of V2 neurons had separable spatial frequency and temporal frequency curves and, according to this criterion, they were not speed selective. The basic functional response characteristics of neurons in area V2 resemble those found in area V1. Our findings show that area V2 together with V1 are important in primate visual processing, especially in locating objects in space and in detecting an object's direction of motion.
