Abstract
Erythema ab igne is a dermatological condition resulting from repeated low-grade heat exposure (below the burning point), which can variably manifest with reticulated erythema and skin hyperpigmentation. Not infrequently, the cause of such a skin disorder is not immediately evident or reported by patients, especially if these are children. Compared to adults, erythema ab igne is rare in children and, if the general practitioners and pediatricians are not aware of this disorder, pediatric patients are often addressed to rheumatologists and/or undergo useless immunological investigations. Here, we performed a systematic case-based review, which finally included 32 cases of pediatric erythema ab igne (in addition to our new clinical report), and discussed the main clinical aspects and issues of this clinical entity in children. In detail, similarities of erythema ab igne with livedo reticularis and/or vasculitis-related rashes sometimes can lead to perform a panel of immunological investigations, which could be avoided. Indeed, our analysis emphasizes the importance of a careful and complete patient's anamnesis, including active questioning about the potential exposure to any physical agents (including heat sources) that may cause dermatological lesions. We also highlight some peculiarities in terms of location and heat injury in children developing erythema ab igne, based on the presence or absence of comorbidities. CONCLUSION The occurrence of erythema ab igne in children (and especially in adolescents) is likely to increase in the next years because of the greater and sometimes inappropriate use of technological devices. Physicians should be aware of this condition in order to prevent patients from useless investigations, especially in the differential diagnosis of rheumatic disorders. A careful and complete patient's history with active questioning about the potential exposure to heating source is often decisive to diagnose erythema ab igne. WHAT IS KNOWN • Erythema ab igne is a dermatological condition which is mainly described in adults exposed to heating source at the workplace. WHAT IS NEW • The occurrence of erythema ab igne in children is likely to increase in the next years because of the greater and sometimes inappropriate use of technological devices. • Erythema ab igne in children can be classified in two main categories, based on the presence or absence of comorbidity. • A careful and complete anamnesis (including the active questioning about potential exposure to any heating source) is the mainstay for diagnosing erythema ab igne in children.

Abstract
Diabetes mellitus (DM) is a non-communicable disease throughout the world in which there is persistently high blood glucose level from the normal range. The diabetes and insulin resistance are mainly responsible for the morbidities and mortalities of humans in the world. This disease is mainly regulated by various enzymes and hormones among which Glycogen synthase kinase-3 (GSK-3) is a principle enzyme and insulin is the key hormone regulating it. The GSK-3, that is the key enzyme is normally showing its actions by various mechanisms that include its phosphorylation, formation of protein complexes, and other cellular distribution and thus it control and directly affects cellular morphology, its growth, mobility and apoptosis of the cell. Disturbances in the action of GSK-3 enzyme may leads to various disease conditions that include insulin resistance leading to diabetes, neurological disease like Alzheimer's disease and cancer. Fluoroquinolones are the most common class of drugs that shows dysglycemic effects via interacting with GSK-3 enzyme. Therefore, it is the need of the day to properly understand functions and mechanisms of GSK-3, especially its role in glucose homeostasis via effects on glycogen synthase.

Abstract
Malaysia is currently experiencing an epidemiologic and demographic transition. Rapid
urbanization and vast changes in lifestyles among the population has led to widespread
cardiovascular disease (CVD) outcomes. Also, until now, the most prevalent
cardiovascular risk factor has remained unknown among the Malaysian population. This
study aimed to identify the most significant cardiovascular risk factor among multiethnic
adults in Dengkil, Selangor. A case-control retrospective study comparing past exposure
(retrospective) between the case (total cholesterol (TC) ≥ 5.18 mmol/L) and control
groups (TC < 5.18 mmol/L) on CVD risk via guided questionnaire comprised of
International Physical Activity Questionnaire (IPAQ), Food Frequency Questionnaire
(FFQ), Depression, Anxiety and Stress Scales (DASS)-21 and SF-12 was carried out
among 180 respondents aged 20 to 56 years in Dengkil, Selangor. In the present study,
purposive and consecutive sampling were both applied to recruit respondents and also
considering ethnic as a factor; thus, quota sampling was also conducted. The data were
analyzed using Mann-Whitney, Kruskal-Wallis, Chi-Square, Independent Samples t-test
and multiple logistic regression tests. The findings indicated there were no significant
differences (p > 0.05) regarding all the risk factors between the case and control groups
except for personal medical history (p < 0.05). Chinese possessed the highest number of
significant risk and protective factors. Lastly, the quality of life of Malay controls was
higher than that of cases in terms of Physical Component Summary (PCS). Generally, all
the risk factors were independent in terms of total cholesterol status, except for personal
medical history. The significance of risk factors and protective factors varies according to
ethnicity.

Abstract
The primary aim of this systematic review was to assess the effect on neonatal outcome of pharmacological interventions used for attenuation of the haemodynamic response to tracheal intubation in patients undergoing caesarean Section under general anaesthesia. A systematic search of randomised controlled trials from 1990 to 2015 was conducted. The primary outcome measure was the Apgar score at five minutes and secondary outcomes were umbilical arterial blood gas parameters and neurological adaptive capacity scores. Twenty-seven randomised controlled trials (1,689 patients) were included in the qualitative synthesis. Only five studies using opioids (383 patients) and five studies using non-opioid analgesics (358 patients) were subjected to meta-analysis. The Apgar score at five minutes was significantly lower in neonates of opioid-treated mothers (mean difference: −0.29, 95% confidence interval −0.56 to −0.02, P-value=0.03) compared to mothers in the control group; the umbilical arterial pH was lower and there was a higher requirement for tactile stimulation in neonates. No difference was seen in Apgar scores of neonates of mothers administered non-opioid analgesics compared to placebo. No difference was observed in other parameters between opioid- or non-opioid-treated mothers. This review suggests that opioid interventions for attenuation of the haemodynamic response to tracheal intubation in pregnant patients under general anaesthesia affect neonatal Apgar scores at five minutes in neonates but the difference did not appear to be clinically meaningful. We were unable to demonstrate any difference in safety.

Abstract
Approved proteasome inhibitors have advanced the treatment of multiple myeloma but are associated with serious toxicities, poor pharmacokinetics, and most with the inconvenience of intravenous administration. We therefore sought to identify novel orally bioavailable proteasome inhibitors with a continuous daily dosing schedule and improved therapeutic window using a unique drug discovery platform. We employed a fluorine-based medicinal chemistry technology to synthesize 14 novel analogs of epoxyketone-based proteasome inhibitors and screened them for their stability, ability to inhibit the chymotrypsin-like proteasome, and antimyeloma activity in vitro. The tolerability, pharmacokinetics, pharmacodynamic activity, and antimyeloma efficacy of our lead candidate were examined in NOD/SCID mice. We identified a tripeptide epoxyketone, FV-162, as a metabolically stable, potent proteasome inhibitor cytotoxic to human myeloma cell lines and primary myeloma cells. FV-162 had limited toxicity and was well tolerated on a continuous daily dosing schedule. Compared with the benchmark oral irreversible proteasome inhibitor, ONX-0192, FV-162 had a lower peak plasma concentration and longer half-life, resulting in a larger area under the curve (AUC). Oral FV-162 treatment induced rapid, irreversible inhibition of chymotrypsin-like proteasome activity in murine red blood cells and inhibited tumor growth in a myeloma xenograft model. Our data suggest that oral FV-162 with continuous daily dosing schedule displays a favorable safety, efficacy, and pharmacokinetic profile in vivo, identifying it as a promising lead for clinical evaluation in myeloma therapy.

Abstract
Body weight and nine body measurements were recorded on 79 mature Kedah-Kelantan cows at two locations. The Kedah-Kelantan is an indigenous cattle of Malaysia. A principal component analysis was used to study size and shape as indicated by the dependence structure among measurements. The total variation among measurements associated with the first principal component which was interpreted as a measure of general size was 40.8%. The second principal component contrasted cows tall at the withers, and deep at the chest with top line sloping downward and under line sloping upward from front to rear with those having less wither height and chest depth and straighter lines. This contrast accounted for 14.3% of the variation in body dimensions. The third principal component contrasted long, narrow, and deeper cows with a more compact type. This contrast accounted for 10.7% of the variation in body dimensions.
