Fasting during the month of Ramadan is one of the five pillars of Islam, a recurring annual ritual, which is passionately practiced by most Muslims across the world. It is obligatory on every healthy Muslim; however, the Qur’an and Islamic teachings specifically exempt people with acute or chronic illnesses from this duty, especially if it might have harmful consequences. Muslims with diabetes are exempted from fasting, but many of them still fast during Ramadan, for their personal convictions as revealed by EPIDIAR study which showed that 43% of patients with type 1 diabetes and 79% with type 2 diabetes fasted during Ramadan. Muslims constitute about a quarter of the world’s population who are spread all over the globe. It is inevitable that health care issues peculiar to them will be encountered worldwide and health care providers will have to counsel them regarding medications and whether it is safe to undertake the fast. This paper is an update on the management of Ramadan fasting based on current evidence from published literature and expert opinions.

Fulltext The effects of different velogenic NDV infections on the chicken bursa of Fabricius

Kristeen-Teo YW, Yeap SK, Tan SW, Omar AR, Ideris A, Tan SG, et al.

BMC Vet Res, 2017 May 31;13(1):151.

PMID: 28569155 DOI: 10.1186/s12917-017-1071-y

BACKGROUND: Virulent Newcastle disease virus (NDV) was reported to cause rapid depletion of chicken bursa of Fabricius. Severe pathological condition of the organ is commonly associated with high levels of virus replication, intense inflammatory response and also the degree of apoptosis. In this study, the responses of chicken bursa of Fabricius infected with two different strains of velogenic NDV, namely AF2240 and IBS002, were investigated by observing cell population changes, oxidative stress, viral replication and cytokine expression in the organ. Subsequently, apoptosis of enriched bursal IgM+ cells was determined to help us elucidate possible host pathogen relationships between the chicken bursa of Fabricius and NDV infection.

RESULTS: The depletion of IgM+ cells and infiltration of macrophages were observed to be higher in bursa infected with AF2240 as compared to IBS002. In line with the increment of the macrophage population, higher nitric oxide (NO) and malondialdehyde (MDA) contents which indicated higher oxidative stress were also detected in bursa infected with NDV AF2240. In addition, higher pro-inflammatory cytokines and chemokine gene expression such as chicken CXCLi2, IL-18 and IFN-γ were observed in AF2240 infected bursa. Depletion of IgM+ cells was further confirmed with increased cell death and apoptosis of the cells in AF2240 infected bursa as compared to IBS002. However, it was found that the viral load for NDV strain IBS002 was comparatively higher than AF2240 although the magnitude of the pro- inflammatory cytokines expression and cell apoptosis was lower than AF2240.

CONCLUSION: The results of our study demonstrated that infection of NDV strains AF2240 and IBS002 caused apoptosis in bursa IgM+ cells and its severity was associated with increased expression of pro-inflammatory cytokines/chemokine, macrophage infiltration and oxidative stress as the infection duration was prolonged. However, of the two viruses, we observed that NDV AF2240 induced a greater magnitude of apoptosis in chicken bursa IgM+ cells in comparison to IBS002. This might be due to the high level of oxidative stress and inflammatory cytokines/chemokine as well as lower IL10 expression which subsequently led to a high rate of apoptosis in the chicken bursa of Fabricius although the detected viral load of AF2240 was lower than IBS002.

Infected poultry meat plays an important role in the spread of Newcastle Disease (ND). In this study, an imported meat product was found to be positive for ND by both virus isolation and molecular characterization. Analysis of the deduced amino acid sequences of the F protein cleavage site showed that the isolate was virulent as indicated by the sequence 112RRQKR116 for the Cterminus of the F2 protein and phenylanine (F) at the N-terminus of the F1 protein, residue 117. Basic Local Alignment Search Tool (BLAST) analysis showed the isolate was 98% identical with China Hebei ND strain. Though the regulations for the importation of poultry meat for human consumption into Malaysia are strict, the possibility of the persistence of ND virus in imported meat is prevalent. Strict enforcement of importing regulations and screening the disease in imported poultry meat is important to ensure food safety and prevent introducing ND strain fInfected poultry meat plays an important role in the spread of Newcastle Disease (ND).

The incidence of diseases related to oxidative stress disorders have been increased dramatically. Alternatives medicine or the active compound extracted from the natural products received great attention among researches at the present era. Naringenin (NG), a common dietary flavanone, found in the citrus fruits such as oranges, bergamots, lemons and grapefruit. It is used in the several oxidative stress disorders as the nutraceutical value of the compound emerges. Functionally, the antioxidants effect of NG is primarily attributed by reducing the free radical like reactive oxygen species (ROS) and enhancing the antioxidants activity such as superoxide dismutase (SOD), catalase, glutathione (GSH) in chronic diseases such as cardiovascular, neurodegenerative, diabetes, pulmonary, cancer and nephropathy. The present review article summarised the antioxidant property of NG and its molecular mechanism towards such diseases. Pubmed, Science Direct, Scopus, Web of Science and Google scholar were searched using the terms 'naringenin', 'oxidative stress disorders', 'naringenin and cardiovascular diseases', 'naringenin and diabetes mellitus', 'naringenin and neurodegenerative diseases', 'naringenin and pulmonary diseases', 'naringenin and cancer' and 'naringenin and nephropathy'. There has been special attention on evaluating anti-oxidative effect of NG on neurodegenerative diseases. Although some mechanisms of action remain vague, the current review highlighted the potential use of NG as a oxidative stress reliever which can be used as next prophylaxis compound in the treatment of the various oxidative stress disorders.

Although individuals with Zika virus (ZIKV) antibodies were reported in Malaya in mid-1950s, entomological and human surveillance in Singapore did not identify autochthonous transmission until the outbreak of August-November, 2016. A total of 455 cases from 15 separate clusters were identified. We asked if this ZIKV outbreak increased the incidence of Guillain-Barré syndrome (GBS) and aimed to characterize these cases. Eleven GBS cases, consecutively enrolled into our prospective GBS database from onset to 4 weeks after outbreak, and six controls, comprising three GBS patients enrolled before outbreak and three non-GBS patients, were examined for evidence of recent ZIKV infection. We performed serum, urine ZIKV RT-PCR, ZIKV serology, and virus neutralization assays, accounting for cross-reaction and co-infection with dengue (DENV). We found five GBS cases with only serological evidence of recent ZIKV infection (including one ZIKV-DENV co-infection). A temporal relationship with ZIKV outbreak was unlikely as two cases were GBS controls enrolled 3 months before outbreak. None reported symptoms of ZIKV infection. In addition, compared to last 10 years the national number of GBS hospitalizations did not increase during and immediately after outbreak. We conclude the 2016 Singapore ZIKV outbreak did not cause a change in GBS epidemiology.

Enterovirus A71 and coxsackievirus A16 show different replication kinetics in human neuronal and non-neuronal cell lines

Yogarajah T, Ong KC, Perera D, Wong KT

Arch Virol, 2017 Mar;162(3):727-737.

Enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16) are closely related enteroviruses that cause hand, foot and mouth disease (HFMD) in children. Serious neurological complications almost always occur in EV-A71 infection, but are rare in CV-A16 infection. Based on the hypothesis that this may be because EV-A71 infects neuronal cells more easily than CV-A16, we compared virus infection, replication and spread of EV-A71 and CV-A16 in SK-N-SH cells. We found that CV-A16 invariably showed significantly lower replication and caused less necrotic cell death in SK-N-SH cells, compared with EV-A71. This was not due to a lower proportion of CV-A16-infected cells, since both viruses showed similar proportions of infected cells at all time points analyzed. Furthermore, reduced replication of CV-A16 in SK-N-SH cells does not appear to be due to limited viral receptor availability, which might limit viral entry, because experiments with viral RNA-transfected cells showed the same results as for live virus infections. On the other hand, no differences were observed between EV-A71 and CV-A16 in RD cells and results were generally similar in RD cells for both viruses. Taken together, our findings suggest that the poor growth of CV-A16 and EV-A71in SK-N-SH cells, compared with RD cells, may be due to cell type-specific restrictions on viral replication and spread. Furthermore, the lower viral replication and necrotic cell death in CV-A16-infected SK-N-SH cells, compared with EV-A71-infected SK-N-SH cells, is consistent with the lower prevalence of neurotropism observed in CV-A16-associated HFMD outbreaks. Nonetheless, in vivo data and more extensive comparisons of different viral strains are essential to confirm our findings.
