    Introduction: Glucose-6-phosphate dehydrogenase (G6PD) deficiency causes red blood cell destruction due to oxi- dative stress. G6PD is essential for NADPH conversion; which is critical for glutathione reductase to prevent damage to cellular structures. In Malaysia, blood donors are not routinely screened for G6PD deficiency. We hypothesise that G6PD-deficient red blood cells are more likely to haemolyse during storage due to increased oxidative molecules. The objectives of this study were to determine the prevalence of G6PD deficiency among blood donors, describe their characteristics and to evaluate the effects of storage on G6PD-deficient donated blood. Methods: This study was conducted at selected mobile donation centres in Terengganu. Consented blood donors were screened for G6PD sta- tus using fluorescent spot tests (FST). G6PD enzyme activities were measured for donors who were G6PD deficient. Effects of storage on haemolysis from G6PD-deficient donors were compared with non G6PD-deficient group. Sixty ml of blood was collected from blood unit to transfer pouch for estimation of haemoglobin (Hb), plasma Hb, per- centage of haemolysis and plasma potassium. Serial sampling with a 7-day interval was done from Day 1 to Day 35. Statistical analysis was considered significant if p 0.05. Results: A total of 440 blood donors were screened and 12 male donors were found to be G6PD deficient by FST. Enzymatic activities were measured in 11 donors as one donor sample failed to be sent to the centre due to logistic problem. Their enzymatic activities ranged from 1.66-2.93 U/g Hb whereby 6 have severe deficiency and the other 5 were categorised as partial deficiency. Donors were asymp- tomatic for haemolytic episode. Serial sampling showed there was no significant difference of haemolytic parameters in blood units of G6PD-deficient donors as compared to control (p>0.05). Conclusion: Prevalence of G6PD blood donors in Terengganu mobile centres was 2.7%. G6PD enzyme activities did not correlate with clinical symptoms. Haemolytic parameters were not affected in blood units which were G6PD-deficient.

    BACKGROUND: Although epidemiological studies report a lower risk of venous thromboembolism (VTE) than in the Western world, VTE rates in Asia may be underestimated. Furthermore, it is uncertain whether VTE outcomes differ in Asia and the rest of the world (ROW).

    METHODS: GARFIELD-VTE is a global, prospective, non-interventional study of real-world treatment practices. In this study, we compared baseline characteristics, treatment patterns, and 12-month outcomes in Asia and ROW.

    RESULTS: Of the 10,684 enrolled patients, 1822 (17.1%) were Asian (China n = 420, Hong Kong n = 98, Japan n = 148, Malaysia n = 244, South Korea n = 343, Taiwan n = 232, Thailand n = 337). Compared with ROW patients, those from Asia were more often female (57.4% vs. 48.0%), non-smokers (74.0% vs. 58.9%) and had a lower BMI (24.8 kg/m2 vs. 29.1 kg/m2). Asian patients were more likely to be managed in the hospital (86.9% vs. 70.4%) and to have active cancer (19.8% vs. 8.1%) or a history of cancer (19.1% vs. 12.0%). Asian patients received no anticoagulation more frequently than ROW patients (6.5% vs. 2.1%). Over 12-months follow-up, the rate of all-cause mortality (per 100 person-years [95% confidence interval]) was higher in Asians (15.2 [13.4-17.3] vs. 5.9 [5.4-6.5]). Adjusted hazard ratios indicated a higher risk of all-cause mortality in Asian patients than the ROW (1.32 [1.08-1.62]). The frequencies of major bleeding and recurrent VTE were similar.

    CONCLUSION: Asian patients have different risk profiles, treatment patterns and a higher risk of mortality compared with the ROW.

    BACKGROUND AND AIMS: Restless legs syndromes (RLS) are intrinsic sleeping disorder and its prevalence rate is 10-15% in general population but it is observed that prevalence rate is different in diabetes patients. Current study aims to find prevalence and determinants of RLS in people living with type 2 diabetes mellitus in Pakistan.

    METHOD: A multicenter cross-sectional observational study was conducted in 388 diabetes patients attending daily diabetes clinics and teaching hospitals in Pakistan's twin city between August 2019 and February 2020. The chi-square test and linear regression were used to detect RLS-related factors in type 2 diabetes mellitus.

    RESULTS: The prevalence of RLS found was; 3.1% patients with diabetes were suffering from very severe RLS, 23.5% from severe RLS, 34% from moderate RLS, 21.1% from mild RLS and 18.3% from non-RLS. Gender, age, education, blood glucose fasting (BSF), blood glucose random (BSR) and HBA1c were found to be significant predictors of RLS in patients with diabetes.

    CONCLUSION: Policy makers can develop local interventions to curb the growing RLS prevalence by keeping in control the risk factors of RLS in people living with type 2 diabetes.

    Mauriac syndrome is a rare and underdiagnosed complication of type 1 diabetes mellitus (T1DM). It is characterized by growth retardation, delayed puberty, Cushingoid features, hepatomegaly, and increased transaminase levels. The term glycogenic hepatopathy has been used to describe patients with poorly controlled T1DM and glycogen overload in the hepatocytes but without all the features of Mauriac syndrome. Although rare, glycogenic hepatopathy is reported to be the main cause of hepatomegaly in young patients with T1DM. We report two cases of glycogenic hepatopathy in children with poorly controlled T1DM. Both children had hepatomegaly, elevated liver enzyme levels, and elevated lactate levels. A liver biopsy confirmed the diagnosis of glycogenic hepatopathy in both patients. In conclusion, hepatomegaly with elevated liver enzymes, negative infective and metabolic screenings and persistently elevated plasma lactate levels should raise the suspicion of glycogenic hepatopathy in poorly controlled T1DM. Early diagnosis and improvement in glycemic control are the mainstays of treatment, which can prevent long-term complications.

    Metabolic syndrome is one of the major risk factors that lead to various serious complications like cardiovascular abnormalities, hyperlipidemia and diabetes. Its co-incidence with other organs dysfunction results in further deterioration of the condition or precipitation of other dysfunctions. This study aimed at studying the changes in the hepatic functions after the co-incidence of the high fat or fructose diets induced metabolic syndrome along with the gentamicin induced nephrotoxicity. Briefly, six groups of male Sprague Daley rats (n = 10-12) were fed with different feeding protocols; viz; standard rodent's chow, an experimental high fat or high fructose diets feedings. For each, two groups were allocated that one of them was injected with normal saline and the other with 80 mg/kg/day I.P gentamicin during the last 24 days of the feeding period. The rats were monitored for changes in the metabolic data, glycemic control, lipid profile, renal and hepatic functions, oxidative stress and the inflammatory response. The study revealed stronger hepatic changes in the renal failure groups fed with the high fat diet rather than that in the groups fed with the high fructose diet. Although, the latter experienced a stronger deterioration in the glycemic control. The study suggests that the incidence of the hepatic changes is more linked to the incidence of the deterioration in the lipids profile that was observed after the high fat diet feeding. Overall, the co-incidence of the high fat diet induced metabolic syndrome along with the renal failure constitutes a risk factor for the hepatic dysfunction.

    Purpose:
    Insulin resistance is a characteristic of non-insulin-dependent diabetes mellitus associated with obesity and caused by the failure of pancreatic beta cells to secrete sufficient amount of insulin. Andrographolide (AND) improves beta-cell reconstruction and inhibits fat-cell formation. This research aimed to improve the delivery of water-insoluble AND in self-nanoemulsifying (ASNE) formulation, tested in streptozotocin (STZ)-induced diabetic rats and 3T3-L1 preadipocyte cells.
    Methods:
    A conventional formulation of AND in suspension was used as a control. The experimental rats were orally administered with self-nanoemulsifying (SNE) and suspension of AND for 8 days. Measurements were performed to evaluate blood glucose levels in preprandial and postprandial conditions. Immunohistochemistry was used to assess the process of islet beta cell reconstruction. In vitro study was performed using cell viability and adipocyte differentiation assay to determine the delivery of AND in the formulation.
    Results:
    ASNE lowered blood glucose levels (day 4) faster than AND suspension (day 6). The histological testing showed that ASNE could regenerate pancreatic beta cells. Therefore, ASNE ameliorated pancreatic beta cells. The in vitro evaluation indicated the inhibition of adipocyte differentiation by both AND and ASNE, which occurred in a time-dependent manner. ASNE formulation had better delivery than AND.
    Conclusion:
    ASNE could improve the antidiabetic activity by lowering blood glucose levels, enhancing pancreatic beta cells, and inhibiting lipid formation in adipocyte cells.

    Introduction: Electronic medical records from hospital information system (HIS) offer a major potential for secondary data analysis which can improve the efficiency of healthcare delivery. This study describes an initiative to use HIS data to explore the level of diabetic care in patients with T2DM in a hospital-based outpatient clinic, the advantages and challenges in utilising HIS data. Methods: Patients age of 18 and above who received any diabetes medication in 2013 were retrospectively identified from HIS of Serdang Hospital. Demographic characteristics, anti-diabetic agent (ADA) dispensed, and glycaemic measures were quantified. Data was extracted using structured query lan- guage (SQL) and descriptive statistical analyses were conducted using Stata Version 12. Results: Prevalence of T2DM patients in the hospital was 7.5%. Male had slightly higher prevalence and patient at age of 61-70 years old. About 62% of patients were prescribed with metformin and 5% of newer combination of oral hypoglycemic agent. In pre- scribing pattern, stratification by age group, showed that patient age 41 to 70 years received mostly monotherapy, whilst 61.1% continue their regime for the year. Only 18% obtained good glycaemic control. Conclusion: Hospital Information system is a critical instrument in providing data as a platform in diabetic care in an outpatient care. Moving forward, steps to improve HIS should be taken to seize its potential as a tool to increase the efficiency of healthcare delivery.

    High-fat diet (HFD) can cause hyperlipidemia, fatty liver and cardiovascular disorders. Herein, we evaluated therapeutic effects and possible underlying mechanisms of actions of Schistosoma mansoni soluble egg antigen (SEA) against experimental HFD induced dyslipidemia, hepatic and cardiovascular pathology. Forty Swiss albino mice were divided into four groups (10 each); mice fed standard diet (SD), mice fed HFD, mice fed HFD for 8 weeks then infected by S. mansoni cercaria (HFD+I) and mice fed HFD for 8 weeks then treated with SEA (HFD+SEA), all mice were euthanized 16 weeks after starting the experiment. HFD+SEA mice showed significantly (p<0.001) reduced total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG), and significantly (p<0.05) increased high-density lipoprotein cholesterol (HDL-C) comparing to HFD mice with non-significant difference with HFD+I mice group. Doppler flowmetry showed significantly (p<0.01) lower arterial resistance and significantly (p<0.05) higher blood flow velocity in HFD+SEA and HFD+I mice groups than HFD mice. HFD+SEA mice revealed improving in liver and aortic pathology and these were better than HFD+I mice group. HFD+SEA and HFD+I mice groups had less myocardium lipid deposits, but still showing some congested blood vessels. HFD myocardium revealed strong CD34+ expression on immunohistochemistry study, while that of HFD+SEA showed weak and HFD+I mice had moderate expressions. HFD+SEA mice had significantly (p<0.01) lower serum IL-1β and vascular endothelial growth factor (VEGF) and significantly (p<0.001) higher serum transforming growth factor beta 1 (TGF-β1) and IL-10 than HFD mice with non-significant difference with HFD+I mice. In conclusion, SEA lowered serum lipids, improved aortic function, decreased liver and cardiovascular pathology in HFD mice, so, it is recommended to purify active molecules from SEA to develop anti-dyslipidemic treatment.

    Many factors contribute to the reluctance towards blood donation, but available studies done in Malaysia involving University students does not reflect the knowledge of the public in general. The objective of this study is to determine knowledge, attitude practice towards blood donation among the Sandakan population. A cross-sectional study was employed using an adapted 29-item structured validated questionnaire available in English and Bahasa, consisting of subject’s demography, questions regarding knowledge, attitude, and perception of blood donation. Convenient random sampling was done within the hospital compound, 79 healthy adults consented, and their data were used for the final data analysis, yielding an excellent internal consistency (Cronbach’s α coefficient = 0.816). Out of all, 74.7% of the respondents had a high level of knowledge, and independent t-tests showed that those who were not married, had tertiary education, donated blood in the past, had a statistically significant higher level of knowledge and 96.2% of respondents have a positive attitude. Some donors (40.6%) donated blood for moral satisfaction, and only a quarter (25%) experienced adverse events. Fear of pain, needle, fainting was the highest reason for reluctance in blood donation (36.2% of non-donors), followed by self-perception of being medically unfit to donate (31.9% of non-donors). Even though the sampled population in Sandakan showed an adequate level of knowledge as well as a positive attitude towards blood donation, blood product shortage is still present. This study may contribute by serving as an educational platform for awareness and education to improve the number of blood donors.

    Objective: To determine the effectiveness of telemedicine in the delivery of diabetes care in low- and middle-income countries.

    Methods: We searched seven databases up to July 2020 for randomized controlled trials investigating the effectiveness of telemedicine in the delivery of diabetes care in low- and middle-income countries. We extracted data on the study characteristics, primary end-points and effect sizes of outcomes. Using random effects analyses, we ran a series of meta-analyses for both biochemical outcomes and related patient properties.

    Findings: We included 31 interventions in our meta-analysis. We observed significant standardized mean differences of -0.38 for glycated haemoglobin (95% confidence interval, CI: -0.52 to -0.23; I2 = 86.70%), -0.20 for fasting blood sugar (95% CI: -0.32 to -0.08; I2 = 64.28%), 0.81 for adherence to treatment (95% CI: 0.19 to 1.42; I2 = 93.75%), 0.55 for diabetes knowledge (95% CI: -0.10 to 1.20; I2 = 92.65%) and 1.68 for self-efficacy (95% CI: 1.06 to 2.30; I2 = 97.15%). We observed no significant treatment effects for other outcomes, with standardized mean differences of -0.04 for body mass index (95% CI: -0.13 to 0.05; I2 = 35.94%), -0.06 for total cholesterol (95% CI: -0.16 to 0.04; I2 = 59.93%) and -0.02 for triglycerides (95% CI: -0.12 to 0.09; I2 = 0%). Interventions via telephone and short message service yielded the highest treatment effects compared with services based on telemetry and smartphone applications.

    Conclusion: Although we determined that telemedicine is effective in improving several diabetes-related outcomes, the certainty of evidence was very low due to substantial heterogeneity and risk of bias.

    Obesity is a known risk factor for non-communicable diseases, including hypertension and diabetes mellitus, with Malaysia having the highest prevalence of obesity among Southeast Asian countries. Additionally, the delivery of medical services to the rural communities remains challenging despite efforts to increase accessibilities to the healthcare facilities. Therefore, regular health screening programmes specifically aiming at these communities are necessary for early diagnosis and intervention to prevent complications while improving the patients’ quality of life. A health screening programme was conducted in a sub-district of Kota Kinabalu, Sabah, Malaysia, where 50 participants were examined for general obesity based on body mass index (BMI) together with central obesity according to waist circumference (WC) and waist-to-hip ratio (WHR). Bioelectrical impedance analysis was performed to estimate body fat percentage (fat%) and body fat mass, along with the measurement of systolic blood pressure (SBP), diastolic blood pressure (DBP), and capillary blood glucose. The median age of the participants was 39.50 years. The prevalence of general obesity, central obesity based on WC and WHR, hypertension, and hyperglycaemia was 28%, 78%, 74%, 24%, and 20%, respectively. Both fat% and fat mass had positive correlations to the BMI (fat%: r = 0.656, p = 0.001; fat mass: r = 0.868, p = 0.001) and WC (fat%: r = 0.505, p = 0.001; fat mass: r = 0.761, p = 0.001). DBP had positive correlations with the BMI (r = 0.390, p = 0.005), WC (r = 0.467, p = 0.001), and WHR (r = 0.331, p = 0.019), while SBP had a positive correlation only with WC (r = 0.341, p = 0.015). Conversely, capillary blood glucose had no significant correlation with either BMI, WC, or WHR. The higher prevalence of central obesity among participants of the health screening program compared to the national level should raise concern among the healthcare providers regarding the future risk for hypertension and hyperglycaemia in this community

    Familial hypercholesterolaemia (FH), the commonest and serious but potentially treatable
    form of inherited dyslipidaemias, is characterised by severely elevated plasma low-density
    lipoprotein-cholesterol (LDL-C) level, which subsequently leads to premature coronary artery
    disease (pCAD). Effectiveness of FH early detection and treatment is supported by the
    outcome of several international cohort studies. Optimal FH management relies on
    prescription of statins either alone or together with other lipid-lowering therapies (LLT).
    Intensive lifestyle intervention is required in parallel with LLT, which should be commenced at
    diagnosis in adults and childhood. Treatment with high intensity statin should be started as
    soon as possible. Combination with ezetimibe and/or bile acid sequestrants is indicated if
    target LDL-C is not achieved. For FH patients in the very-high risk category, if their LDL-C
    targets are not achieved, despite being on maximally tolerated statin dose and ezetimibe,
    proprotein convertase subtilisin/kexin type1 inhibitor (PCSK9i) is recommended. In statin
    intolerance, ezetimibe alone, or in combination with PCSK9i may be considered. Clinical
    evaluation of response to treatment and safety are recommended to be done about 4-6 weeks
    following initiation of treatment. Homozygous FH (HoFH) patients should be treated with
    maximally tolerated intensive LLT and, when available, with lipoprotein apheresis. This review
    highlights the overall management, and optimal treatment combinations in FH in adults and
    children, newer LLT including PCSK9i, microsomal transfer protein inhibitor, allele-specific
    oligonucleotide to ApoB100 and PCSK9 mRNA. Family cascade screening and/or screening
    of high-risk individuals, is the most cost-effective way of identifying FH cases and initiating
    early and adequate LLT.

    Natural compounds have tremendous potential to regulate glucose metabolism, but conventional methods for studying their bioactivities are usually labor intensive. Here, hypoglycemic properties in 22 selected food-derived compounds were examined using molecular docking. The results indicated that curcumin is an inhibitor of both α-glucosidase and dipeptidyl-peptidase 4 (DPP-4), which are important for glycemic control. These effects of curcumin were also confirmed by enzymatic determination in vitro. Furthermore, curcumin significantly improved diet-induced hyperglycemia (e.g., fasting plasma glucose levels and glycogen storage in muscle or liver) in mice. This might be attributed to its inhibitory effects on the activities of α-glucosidase and DPP-4 in vivo. Curcumin also upregulated the expression of genes (e.g., glucagon-like peptide 1) related to DPP-4 activity in the small intestine. In conclusion, curcumin is a potential ingredient of functional foods used for diet-induced hyperglycemia management. PRACTICAL APPLICATIONS: Curcumin has been widely used as a colorant in the food industry. Moreover, a growing number of studies have described its diverse biological functions, such as anti-inflammatory, anti-oxidant, and anti-angiogenic activities. Thus, curcumin is regarded as a potential ingredient in functional foods. Our results highlighted the hyperglycemic effect of curcumin, suggesting that curcumin may be included in food products for hyperglycemic patients.

    Cerebral venous thrombosis (CVT) is a neurological condition occurring because of thrombosis involving the cerebral venous sinuses. This case report is an unusual clinical manifestation of cerebral venous thrombosis in a 76-year-old Chinese man who presented with restricted eye movement and double vision. Despite extensive investigation, there was no better explanation for his clinical symptom and sign apart from cerebral venous thrombosis which was confirmed by magnetic resonance venography (MRV) of the brain. Once cerebral venous thrombosis was diagnosed, he was initiated on anticoagulation and discharged with oral warfarin. This case emphasizes the need to consider cerebral venous thrombosis as one of the rare causes of complex ophthalmoplegia especially when typical cardiovascular risk factors are lacking in an individual.

    Leptin, a 16 kDa protein and a product of the ob/ob gene, has a tertiary structure similar to that
    of a cytokine. It is primarily secreted by white adipose tissue and its levels in the blood correlate
    positively with percentage body fat. Leptin was first identified in 1994 as a major factor that
    regulated food intake and energy balance. Leptin in the circulation exists either as a free
    monomeric hormone or bound to its soluble receptor. Its serum levels usually range from 0.5 to
    37.7 ng/ml in males and 2.0 to 45.2 ng/ml in females. The half-life of leptin is between 20 - 30
    minutes and it is eliminated mainly by the kidneys. However, research over the last 25 years
    has revealed numerous other physiological roles for leptin, including roles in inflammation,
    immune function, neuro-endocrine function, bone metabolism, blood pressure regulation and
    sexual maturation. Most of these roles have been identified from studies on leptin deficient
    rodents. Apart from energy balance and sexual maturation, where its role is direct and obvious,
    its actions on the rest of the other systems are permissive. Actions of leptin are both centrally
    and peripherally mediated involving receptors that are widely distributed in the body. Six leptin
    receptor isoforms, belonging to the class 1 cytokine receptor family, have been identified.
    These receptors are products of the OBR gene. The cellular actions of leptin are mediated
    through any one of five different signalling pathways that include the JAK-STAT, PI3K, MAPK,
    AMPK, and the mTOR signalling pathways.

    Hereditary or developmental neurological disorders (HNDs or DNDs) affect the quality of life and contribute to the high mortality rates among neonates. Most HNDs are incurable, and the search for new and effective treatments is hampered by challenges peculiar to the human brain, which is guarded by the near-impervious blood-brain barrier. Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR), a gene-editing tool repurposed from bacterial defense systems against viruses, has been touted by some as a panacea for genetic diseases. CRISPR has expedited the research into HNDs, enabling the generation of in vitro and in vivo models to simulate the changes in human physiology caused by genetic variation. In this review, we describe the basic principles and workings of CRISPR and the modifications that have been made to broaden its applications. Then, we review important CRISPR-based studies that have opened new doors to the treatment of HNDs such as fragile X syndrome and Down syndrome. We also discuss how CRISPR can be used to generate research models to examine the effects of genetic variation and caffeine therapy on the developing brain. Several drawbacks of CRISPR may preclude its use at the clinics, particularly the vulnerability of neuronal cells to the adverse effect of gene editing, and the inefficiency of CRISPR delivery into the brain. In concluding the review, we offer some suggestions for enhancing the gene-editing efficacy of CRISPR and how it may be morphed into safe and effective therapy for HNDs and other brain disorders.

    High-intensity exercise acutely improves suppression of appetite in populations with normal body mass index (BMI). However, whether moderate intensity exercise (MIE) and high-intensity exercise (HIE) can elicit similar (or greater) appetite suppression effects for obese populations are still relatively unknown. The main aim is to investigate the acute effects of MIE and HIE on the appetite score, eating behaviour and blood glucose regulation among the obese population. Twelve obese participants (age: 20.8 ± 1 yr, BMI: 34.1 ± 3 kg·m-2, V̇o2max: 30.7 ± 3 ml·kg·min-1) were randomly allocated, in a crossover manner, with a 7-day interval in between (1) MIE (cycling at 60-75% HRmax), (2) HIE (cycling at 80-95% HRmax, 8-sec sprint x 12 sec rest) and (3) control (CON) condition after a 10-hr overnight fast. Physiological (fasting blood [glucose] and 24-hr calorie intake) and psychological responses (Three Factor Eating Questionnaire-R18, TFEQ-R18, and appetite score using Visual Analog Scale, VAS) were recorded prior to and after exercise interventions. Both MIE and HIE significantly reduced the calorie intake compared to CON (P0.05). A difference was found in fasting blood [glucose] level between trials in MIE (P0.05). In response to acute intervention, both MIE and HIE improved some psychological appetite score and attenuated daily energy consumption; these positive effects could benefit obese and diabetic populations.

    PURPOSE: IDegAsp, a co-formulation of long-acting basal (insulin degludec) and rapid-acting bolus (insulin aspart) insulin, provides separate prandial and basal glucose-lowering effects with relatively low risk of hypoglycaemia. Its efficacy and safety have been investigated in a large clinical trial programme (BOOST). We present the rationale and design of the ARISE study, which aims to assess glycaemic control and other clinical parameters associated with IDegAsp use in real world.

    METHODS: ARISE is a ~26-wk-long, prospective, non-interventional, single-arm study of patients with type 2 diabetes (T2D) initiating IDegAsp treatment. Approximately 1112 patients with T2D aged ≥18 years previously on anti-hyperglycaemic drugs except IDegAsp will be enroled across six countries from 15 Aug 2019 to 12 Nov 2020. IDegAsp treatment will be initiated at the physicians' discretion and as per the local label. Key exclusion criteria include previous participation, or previous IDegAsp treatment. The primary and secondary endpoints are change in HbA1c from baseline (wk 0) to study end (wk 26-36) and the proportion of patients achieving the target HbA1c level of <7% at the study end, respectively. A mixed model for repeated measurements will analyse the primary endpoint.

    CONCLUSION: Between-country differences in the prescription patterns of glucose-lowering agents in people with T2D warrant examination of their clinical use in different geographical settings. The ARISE study is designed to assess the clinical use of IDegAsp from real world in six different countries. Findings from the ARISE study will supplement those of previous randomised controlled studies by establishing real-world evidence of IDegAsp use in the participating countries.

    OBJECTIVE: The use of platelet concentrates (PCs) in oral and maxillofacial surgery, periodontology, and craniofacial surgery has been reported. While PCs provide a rich reservoir of autologous bioactive growth factors for tissue regeneration, their drawbacks include lack of utility for long-term application, low elastic modulus and strength, and limited storage capability. These issues restrict their broader application. This review focuses on the lyophilization of PCs (LPCs) and how this processing approach affects their biological and mechanical properties for application as a bioactive scaffold for craniofacial tissue regeneration.

    MATERIALS AND METHODS: A comprehensive search of five electronic databases, including Medline, PubMed, EMBASE, Web of Science, and Scopus, was conducted from 1946 until 2019 using a combination of search terms relating to this topic.

    RESULTS: Ten manuscripts were identified as being relevant. The use of LPCs was mostly studied in in vitro and in vivo craniofacial bone regeneration models. Notably, one clinical study reported the utility of LPCs for guided bone regeneration prior to dental implant placement.

    CONCLUSIONS: Lyophilization can enhance the inherent characteristics of PCs and extends shelf-life, enable their use in emergency surgery, and improve storage and transportation capabilities. In light of this, further preclinical studies and clinical trials are required, as LPCs offer a potential approach for clinical application in craniofacial tissue regeneration.

    Background: Traditional Siddha Medicine advises using metal-based formulations to treat cancers. In the case of any toxicities during the therapy, Siddha physicians use Vernonia cinerea (VC) whole plant kashayam (crude aqueous extract-CAE) to reverse the toxic effects.

    Aim: To evaluate the nephroprotective activity of CAE and its fractions in cisplatin-induced nephrotoxicity and to assess whether they compromise the anticancer efficacy of cisplatin.

    Materials and methods: Cisplatin-induced renal damage was induced in Ehrlich Ascites Carcinoma (EAC) bearing mice during mild phase of tumor growth. CAE and its butanol (BF) and aqueous (AF) fractions were administered orally from the 5th day for five days. Nephroprotective potential (serum urea, creatinine, renal histology) and effect of VC on cisplatin anticancer efficacy (tumor volume, viable tumor cells, percentage increase in life span (% ILS)) were calculated.

    Result: CAE and its fractions significantly reversed the cisplatin-induced renal damage. CAE and BF treated animals showed regeneration of 50%-75% of proximal tubular cells. Compared to EAC control mice, the % ILS of the cisplatin-treated group was 244% and it was further extended to 379% after CAE administration. The % ILS in the CAE treated group was 1.6 times higher than the cisplatin alone treated group. GC-MS study showed the presence of astaxanthin and betulin.

    Conclusion: CAE of VC reverses cisplatin-induced kidney damage as well as regenerates proximal tubular epithelial cells, without compromising the anticancer effect of cisplatin. When CAE was further fractionated, the nephroprotective activity was retained, but the beneficial anticancer effect of cisplatin was compromised.
