This investigation describes the impacts of dietary provisioning with astaxanthin on hemato-biochemistry, non-specific immunity, and disease resistance of the Asian seabass, Lates calcarifer, against the virulent Vibrio alginolyticus; with specific reference to dose-response associations and variations over different post-infection periods (0-, 7-, and 14-day). Triplicate groups of fish weighing 28 g, on average, were fed various diets (C, the control or astaxanthin-free; AXT50, 50 mg astaxanthin kg-1 diet; AXT100, 100 mg astaxanthin kg-1 diet; and AXT150, 150 mg astaxanthin kg-1 diet) for 90 days and subsequently challenged with V. alginolyticus at the end of the feeding period. Experimental infection unveiled that supplemented fish demonstrated significant improvements (P

Fulltext Reduced red blood cell deformability in Plasmodium knowlesi malaria

Barber BE, Russell B, Grigg MJ, Zhang R, William T, Amir A, et al.

Blood Adv, 2018 02 27;2(4):433-443.
PMID: 29487058 DOI: 10.1182/bloodadvances.2017013730

The simian parasite Plasmodium knowlesi can cause severe and fatal human malaria. However, little is known about the pathogenesis of this disease. In falciparum malaria, reduced red blood cell deformability (RBC-D) contributes to microvascular obstruction and impaired organ perfusion. In P knowlesi infection, impaired microcirculatory flow has been observed in Macaca mulatta (rhesus macaques), unnatural hosts who develop severe and fatal disease. However, RBC-D has not been measured in human infection or in the natural host M fascicularis (long-tailed macaques). Using ektacytometry, we measured RBC-D in adults with severe and non-severe knowlesi and falciparum malaria and in healthy controls. In addition, we used micropipette aspiration to determine the relative stiffness of infected RBCs (iRBCs) and uninfected RBCs (uRBCs) in P knowlesi-infected humans and M fascicularis Ektacytometry demonstrated that RBC-D overall was reduced in human knowlesi malaria in proportion to disease severity, and in severe knowlesi malaria, it was comparable to that of severe falciparum malaria. RBC-D correlated inversely with parasitemia and lactate in knowlesi malaria and HRP2 in falciparum malaria, and it correlated with hemoglobin nadir in knowlesi malaria. Micropipette aspiration confirmed that in humans, P knowlesi infection increased stiffness of both iRBCs and uRBCs, with the latter mostly the result of echinocytosis. In contrast, in the natural host M fascicularis, echinocyte formation was not observed, and the RBC-D of uRBCs was unaffected. In unnatural primate hosts of P knowlesi, including humans, reduced deformability of iRBCs and uRBCs may represent a key pathogenic mechanism leading to microvascular accumulation, impaired organ perfusion, and anemia.

Introduction: Childhood stunting is recognised as one of the most significant
barriers to human development. This cross-sectional study aimed to determine the
factors associated with stunting among Orang Asli (OA) preschool children in Negeri
Sembilan, Malaysia.

Methods: A total of 264 children (50.9% boys and 49.1%
girls) aged 2-6 years (M=4.04, SD=1.21 years) including their mothers from 14 OA
villages in Negeri Sembilan participated in this study. Mothers were interviewed to
obtain information regarding socioeconomic status, sanitation facility and personal
hygiene. The height of the children and their mothers were measured. Venous
blood samples were drawn from the children to estimate haemoglobin level, and
stool samples were collected to screen for intestinal parasitic infections.

Results:
Approximately one third of the children (35.6%) and 7.8% of the mothers were
stunted. One in five of the children were anaemic (21.6%), while one- third had
intestinal parasitic infections (35.0%). Low birth weight (AOR=2.526, 95% CI: 1.310-
4.872; p=0.006), anaemia (AOR=2.742, 95% CI: 1.265-5.945; p=0.011), presence
of intestinal parasitic infections (AOR=2.235, 95% CI: 1.310-3.813, p=0.003), not
wearing shoes (AOR=2.602, 95% CI: 1.453-4.660; p=0.001), absence of piped water
at home (AOR=2.395, 95% CI: 1.047-5.476; p=0.039), dirty nails (AOR=1.956, 95%
CI: 1.163-3.289, p=0.011), and stunted mothers (AOR=3.443, 95% CI: 1.334-8.890;
p=0.011) were identified as significant factors for childhood stunting.

Conclusion:
It is suggested that the factors identified associated with childhood stunting be
included in future intervention programmes that address stunting among OA
children.

Management of Beta (β)-thalassaemia intermedia in contrast to β-thalassaemia major patients has no clear guidelines as to indicators of adequate transfusion. Regular blood transfusion suppresses bone marrow erythropoietic activity. Serum soluble transferrin receptor (sTfR) concentration is a marker for erythropoietic activity, with increased sTfR being associated with functional iron deficiency and increased erythropoietic activity. This study aimed to determine the use of sTfR as an indicator of adequate transfusion in adult β-thalassaemia intermedia patients. A cross-sectional study was conducted at Hospital Ampang, Malaysia, for six months. Patient group included six β-thalassaemia intermedia and 34 HbE-β-thalassaemia transfused patients. None of the patients were on regular monthly blood transfusions as in β-thalassaemia major. The control group comprised of 16 healthy subjects with normal haematological parameters. Haemoglobin (Hb) analysis, sTfR and ferritin assays were performed. Hb and HbA percentages (%) were found to be significantly lower in patients compared to the controls, while HbE%, HbF%, sTfR and ferritin were significantly higher in patients. An inverse relationship was found in the controls between HbF% with Hb (r = -0.515, p < 0.05) and HbA% (r = -0.534, p < 0.05). In patients, sTfR showed an inverse relationship with HbA% (r = -0.618, p = 0.000) and a positive correlation with HbE% (r = 0.418, p = 0.007) and HbF% (r = 0.469, p = 0.002). Multivariate analysis showed that HbA% (r = 2.875, p = 0.048), HbE% (r = 2.872, p = 0.020) and HbF% (r = 2.436, p = 0.013) best predicted sTfR independently in patients. Thus, sTfR is a useful marker for erythropoiesis. The elevated sTfR in these patients indicate that the transfusion regimen used was inadequate to suppress ineffective erythropoiesis. Hb levels may not be the best target for monitoring transfusion treatment in β-thalassaemia intermedia patients, but the use of sTfR is helpful in individualising transfusion regimens.

Background : Anemia in pregnancy is a worldwide problem. Ministry of Health Malaysia has conducted prophylaxis program to distribute hematinic pills to pregnant women since 3 decades ago.
Methodology : A cross sectional study was conducted among pregnant women who attended government health clinics in Johor Bahru district to assess the prevalence of taking iron tablet and factors associated with it by using a structured questionnaire.
Result : Prevalence of respondents taking ferrous pill daily was 68.6%. Anemia prevalence found in this study was 37.5%. Majority of the respondents did not take pills regularly said their reason as forgotten(54.0%), side effects caused by taking pill (39.3%) and did not like the taste (6.7%). The haemoglobin mean was directly inclined with frequency of ferrous pill intake. The significant associated factor in taking iron pill was only frequency of drinking tea. Multivariate logistic regression analyses revealed that drinking tea was the only factor that contributing to iron pills consumption.
Conclusion : Education is the most important factor in improving adherence to iron pill. Besides that, motivation and behaviour modification of pregnant women also needs to be taken into account.

Fulltext Reduction of tear-drop poikilocytes in a case of myelofibrosis following splenectomy

Chooi, Fun Leong, Soon, Keng Cheong

Medicine & Health, 2006;1(1):81-84.
MyJurnal

Myelofibrosis is a chronic myeloproliferative disorder characterised by splenomegaly, leukoerythroblastic anaemia, tear-drop poikilocytosis and marrow fibrosis. Splenectomy is indicated for patients requiring frequent transfusions or massive splenomegaly causing distressing symptoms and severe thrombocytopenia secondary to hypersplenism.A 56 year-old lady diagnosed to have primary myelofibrosis in year 2000 was referred to HUKM for further management of her increasing requirement of blood transfusion and massive splenomegaly. She has had two episodes of acute cholecytitis. Investigations done in our hospital showed that her hemoglobin level was 6.4g/dl, white cell count of 23.4x109/l, platelet count 163x109/l and peripheral blood showing leukoerythroblastic picture and tear-drop poikilocytosis. Leukocyte alkaline phosphatase score (NAP) was 184/100 neutrophils. Ultrasound of the abdomen showed massive splenomegaly with multiple gall stones. In view of the frequent transfusion requirements and symptomatic massive splenomegaly, splenectomy and cholecystectomy was performed. A review of her peripheral blood picture, post-splenectomy, showed marked reduction of the tear-drop poikilocytosis and leukoerythroblastosis. We believe that the spleen plays an important role in their formation, but the exact mechanism remains unclear.

This study was conducted to determine the health status of aboriginal ("Orang Asli') children aged 0-12 years in Post Brooke, Gua Musang, Kelantan. This is done by appraising the environmental status, patterns of illnesses including communicable diseases and usage of health resources. Six villages were selected randomly from 12 villages in the area; 179 families were interviewed, 200 under-12-year-olds were examined and their blood samples taken for haemoglobin (HB) estimation as well as malarial screening. Water supply through Gravity Feed System (GFS) was used by 134 families (70.2%) whilst the rest obtained water direct from the river for the purpose. Only 63.6% of families boiled their drinking water 56.4% families threw rubbish indiscriminately, while 82.1% used the river as their toilets. Eighty-seven percent of the families saw the village medicine man first when ill. Forty (22.2%) children had had serious illnesses including malaria and 24 were admitted to hospitals. 15% of the children had never been immunized. A total of 102 (51%) children were pale and 90 (45%) had brown hair. Eighty nine (44.5%) of the children were anaemic (Hb < 10 gm/di). Sixty-nine children (34%) had dental caries. Forty-two (21%) had distended abdomen and 37 (18.5%) had hepatomegaly. Out of 84 stool samples examined, 67 (79.8%) had helminthic ova. Of all families, 47.1% gave a past history of at least one baby among their children who had died due to one reason or another. The health status of this community (especially children) was low that it warrants special attention.

MyJurnal

Fulminant haemorrhage in cervical cancer leads to severe anaemia and haemodynamic instability. Palliative management includes vaginal packing as temporary measure, radiotherapy and other invasive surgical procedures. High dose emergency chemotherapy is not commonly implemented particularly when complicated with anaemia and renal impairment. We discuss three case series on the usefulness of high dose chemotherapy to combat bleeding from cervical cancer as an emergency treatment. The first case was clinically staged as operable 2A disease with severe anaemia due to bleeding from the tumour mass. The haemoglobin was corrected by blood transfusion while the bleeding was being arrested by high dose chemotherapy. The second case was inoperable with invasion to the bladder mucosa. She had frank haematuria and bleeding from the tumour with severe anaemia. A course of chemotherapy and blood transfusion controlled the bleeding and anaemia was corrected. The third case presented late with obstructive uropathy and anaemia. She required dialysis, blood transfusion and high dose emergency chemotherapy to stop the bleeding before undergoing urinary diversion after an unsuccessful ureteric stenting. High dose chemotherapy consisting cisplatin, vincristine, bleomycin and mitomycin-C has a clinical value in arresting fulminant haemorrhage in cervical cancer.

Introduction : A retrospective cohort study was conducted among ESRD who received dialysis treatment (Haemodialysis and CAPD) in all government hospitals in the State of Pahang from 1st January 2000 to 31st December 2004.
Objective : The aim of the study was to identify factors affecting the survival of patients undergoing dialysis in the state of Pahang.
Methods : Survival time was measured from the date of dialysis until the subjects died, lost to follow up or until the end of the study period at 31st December 2004.
Results : Diabetes mellitus was the major cause for ESRD (33%) out of 132 subjects eligible for the study. Seven (7.1%) and five (15.2%) deaths occurred among haemodialysis and CAPD patients respectively, but statistically of no difference between the two treatments (log-rank, p=0.093). Factors influencing the survival of haemodialysis patients were diabetes mellitus (p=0.014), albumin (p=0.0005), creatinine (p=0.020) and hemoglobin level (p=0.002), while age of treatment and diabetes mellitus affecting the survival of CAPD patient. Cox Proportional Hazard Regression showed that haemodialysis subjects with low albumin (HR 0.669 df 95% 0.513 - 0.873) and hemoglobin (HR 0.403 df 95% 0.225 - 0.720) level had lower survival rate but none for CAPD.
Conclusion : Good nutritional status, higher hemoglobin level and prevention of diabetes mellitus are important for the survival of haemodialysis patient.

The relationship between anaemia and cognitive function was evaluated among 35 Chinese elderly (24 men and 11 women) aged 60 to 85 years (mean age 70.1 ± 6.7 years) from five old folks homes in Klang Valley. They were interviewed to obtain information on social and health status, habitual dietary intake and cognitive function. Hodkinson's Abbreviated Mental Test was used to measure the cognitive function. Haematological indices which included Full Blood Count (FBC), serum iron, serum ferritin, Total Iron Binding Capacity (TIBC), serum folate and serum cobalamine (vitamin B12) were measured using an automated analyzer. Anthropometric measurements and clinical signs of anaemia were also examined. The findings indicated that the prevalence of anaemia as assessed using haemoglobin alone was 22.9%, while iron deficiency anaemia based on low serum iron, microcytic and hypochromic criterion was detected among 5.7% of the sample. Subclinical folate and vitamin B12 deficiencies were diagnosed among 34.3% and 8.6% of the subjects. However, there was no occurrence of megaloblastic anaemia. There was a positive correlation between cognitive score with mid upper arm circumference (MUAC) (r=0.547, p

Health awareness promotion among farming communities are important for a sustainable agriculture activities. A cross-sectional study was conducted to assess health status among farming communities in Cameron Highlands, Pahang (n = 61) and Bachok and Pasir Puteh, Kelantan (n = 143). Mobile Health Screening Programme composed of assessment of blood glucose, blood cholesterol, haemoglobin, blood pressure, pterygium, lung function and nerve conductive velocity was utilized. Our results indicate that the percentage of Cameron Highland’s farmers with hyperglycaemia, systolic hypertension, diastolic hypertension and anaemia were 8.2%, 14.8%, 11.5% and 8.2%, respectively. However, higher percentage of farmers in Bachok and Pasir Puteh, Kelantan with hyperglycaemia (32.8%), hypercholesterolaemia (83%), anaemia (24.2%) and systolic hypertension (41.9%) were observed. Pterygium was positive for 88.6% of farmers in Cameron Highlands and 94.4% in Bachok and Pasir Puteh. Lung function test shows that 61.7% and 11.4% of farmers in Cameron Highlands had restrictive and obstructive lung, respectively. In Bachok and Pasir Puteh, a total of 19.8%, 55.5% and 23.9% of farmers were found to have obstructive, restrictive and combined obstructive and restrictive lung, respectively. Current Perception Threshold (CPT) value which indicate nerve conductive velocity were significantly increased (p < 0.05) among Cameron Highland’s farmers for both median and peroneal nerve at all frequencies (5 Hz, 250 Hz and 2000 Hz). In Bachok and Pasir Puteh, the values of the CPT for median nerve was significantly increased (p < 0.05) for all frequencies (5, 250 and 2000 Hz). Meanwhile, a signifi cant increased (p < 0.05) was observed for the CPT values for peroneal nerve at the frequencies of 250 and 2000 Hz as compared to control groups. In conclusion, analysis revealed different health problem among the studied farming communities which could be influenced by the differences in farming practices. Thus, employed Mobile Health Screening Programme offers a monitoring approach that could highlight the need for suitable health services and awareness programmes for different farming communities.

Adequate nutrition is important for mothers and their offspring during and after birth. This cross sectional study was conducted to determine nutritional status and nutritional knowledge of pregnant women from two selected private hospitals in Klang Valley, Malaysia. A total of 236 Malay pregnant women aged between 20 to 45 years old (mean age 31+5 years) were recruited through convenient sampling method. Socio-demographic data, nutritional knowledge and a 24-hours diet recall were obtained through a self-administered questionnaire. Anthropometric and haemoglobin data were obtained from the antenatal records in the respective hospitals. The percentages of participants who were underweight, normal, overweight and obese before pregnancy were 12.7%, 55.1%, 25.0% and 7.2% respectively. Among those who were obese before pregnancy, a total of 59.7% had inadequate weight gain, 24.6% gained adequate weight and 15.7% gained excessive gestational weight. About 33.5% of subjects were anaemic (Hb < 11.0g/dL). The mean daily energy intake of the participants was 1748 ± 526 kcal which was 76% of RNI. Calcium (73% of RNI), folic acid (36% of RNI), niacin (89% of RNI) and vitamin D (40% of RNI). The nutritional knowledge level of subjects was moderate (51.9 ± 13.8%). Lower monthly household income (p < 0.001), educational level (p < 0.001) and gestational stage (p < 0.05) of participants were associated with a lower nutritional knowledge level. Nutritional knowledge score was positively correlated with gestational weight gain (r = 0.166, p < 0.05) and haemoglobin level (r = 0.200, p < 0.05). Subjects who claimed practising food taboos had higher nutritional knowledge score (54.9 ± 12.5%) than those who did not (49.9 ± 14.4%)(p < 0.05). A comprehensive nutrition education should be integrated in the antenatal classes to improve nutritional status of pregnant women.

A cross-sectional study was undertaken to evaluate if outpatient administration of in-travenous iron sucrose complex (Venofer) was a sensible option in treating iron defi-ciency anaemia during pregnancy and puerperium. A total of 120 patients with iron deficiency anaemia were recruited from the Obstetric Day Care Clinic at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) over 18 months from March 2003 to August 2004. The main outcome measures were haemoglobin increment, patients’ compliance, adverse effects and saving from hospitalization fees. The pre-treatment haemoglobin (Hb) level was 8.5+0.85g/dl for the antenatal patient and 7.6+0.80 g/dl in the post-partum group. The mean post-treatment haemoglobin increment at day four-teenth was 3.52+0.75g/dl. One patient developed skin rash while another had low-grade pyrexia. Seven patients experienced mild metallic taste. There were no serious side effects or anaphylactic reactions. Ten patients (8.3%) did not complete their ther-apy - eight delivered before completion of treatment; another two defaulted following delivery. The average number of Venofer used was seven ampoules i.e. 700mg per person, most of them required three sessions to complete the course. Outpatient treatment allows each patient to save hospitalization fees of RM45 per day, which to-talled up to RM135 for a 3-days ward stay. An estimation of RM16,200 hospitalization fees for the 120 patients was avoided during the study period. In conclusion, outpatient treatment of anaemia in pregnancy and post-partum period using Venofer was safe and feasible, with high patient compliant and cost-savings from hospitalization fees.

PMID: 28717318 DOI: 10.14202/vetworld.2017.655-661

AIM: This study was conducted to analyze the changes in blood profile of goats inoculated with Corynebacterium pseudotuberculosis and its immunogen mycolic acid (MA) extract.
MATERIALS AND METHODS: A total of 12 clinically healthy crossbred Boer female goats were divided into three groups; A, B and C (4 goats each per group). Group A was inoculated with 2 ml sterile phosphate buffered saline via intradermal route as the negative control group whilst Group B was inoculated with 2 ml of MA extract (1 g/ml) intradermally and Group C was then inoculated with 2 ml (1×10(9)) colony forming unit of active C. pseudotuberculosis intradermally. Blood sample was collected aseptically from the jugular vein periodically for complete blood count (CBC) analysis throughout the experimental period (3 months).
RESULT: A significant decrease (p<0.05) was observed in red blood cells, hemoglobin (Hb), packed cell volume, mean corpuscular volume and mean corpuscular Hb concentration in Groups B and C as compared to the control while WBCs, neutrophil, lymphocyte and basophil showed a significant increase (p<0.05) as compared to the control.
CONCLUSION: The inoculation of C. pseudotuberculosis and MA resulted in a significant change in the CBC, thereby, indicating that MA has a role in caseous lymphadenitis pathogenesis.

PMID: 30211075 DOI: 10.15171/bi.2018.18

Introduction:
Obesity is commonly linked up with several life-threatening diseases. This study aims to investigate the association of fatty acid synthase (FASN) rs4246445, rs2229425, rs2228305, and rs2229422 single nucleotide polymorphisms (SNPs) with the risk of overweight and obesity in the Malaysian population.
Methods:
Blood samples were collected from 1030 individuals who were grouped into normal, overweight, and obese categories. Blood biochemistry test and lipid profiling were performed and genomic DNA was extracted. Genotyping was performed using hydrolysis probes and odd ratio with 95% CI was calculated for risk association analysis. Linkage disequilibrium and haplotypes analyses were carried out using SHEsis software.
Results:
We found that the hemoglobin and white blood cell counts were significantly high in the obese subjects. There is a lack of evidence to link the FASN SNPs with the risk of overweight and obesity in the population. All 4 SNPs were seemed to be in linkage equilibrium. Five common haplotypes were identified in this study but none of them was significantly associated with overweight and obesity in the population.
Conclusion:
Our findings suggest a lack of evidence to associate the FASN rs4246445, rs2229425, rs2228305, and rs2229422 SNPs with the risk of overweight and obesity in the Malaysian population. All 4 SNPs were independent of each other and not all identified haplotypes were significantly associated with overweight and obesity in this study.

PMID: 30186328 DOI: 10.1155/2018/8425985

We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal center type, CD20 positive, and proliferative index 95% was confirmed via renal biopsy, and there was no bone marrow infiltrates. Unfortunately, the patient succumbs prior to initiation of chemotherapy.

Toxicological evaluation of dried kacangma herb (Leonurus sibiricus) in rats

Chua HP, Aminah Abdullah, Murugaiyah M

Sains Malaysiana, 2009;38.

Kacangma (Leonurus sibiricus L.) is a popular traditional herb that has been consumed for decades by the people of Sarawak as a herbal medicine or culinary ingredient. The toxicity of dried kacangma herb on Sprague Dawley male and female rats was evaluated through 90-day sub-chronic studies. The rats were fed kacangma at the rate of 0.5 (low dose), 5 (medium dose) and 25 (high dose) g/kg body weight. The control groups of rats received only the commercial rat pellet. Minor treatment-related effects were observed for body weights, organ weights and the lipid profile parameters and these did not appear to be of toxicological significance. In the sub-chronic toxicity studies, some indications of renal and liver toxicity were evident in the medium and high dose groups when plasma creatinine and liver enzymes were found to be higher when compared with the control and the low dose groups. The hematology study reveals statistically significant mild anemia in rats from the medium and high dose groups as indicated by decreases in hemoglobin, red blood cell count and packed cell volume (hematocrit value). Administration of kacangma herb at medium and high dose was also found to cause adverse effects in histopathological structure of the liver and kidney of both male and female rats. However, low dose group showed no significant differences compared to the control. Therefore, it is considered safe and less chance of developing toxicity if the herb is consumed at the dose of 0.5 g/kg body weight as observed throughout the 90 days period of sub-chronic study.

Hepatic phosphoprotein levels are altered in mouse liver as a manifestation of bacteria, virus or parasite infection. Identification of signaling pathways mediated by these hepatic proteins contribute to the current understanding of the mechanism of pathogenesis in malarial infection. The present study was undertaken to evaluate the changes in hepatic phosphoprotein levels during Plasmodium berghei infection. Our study revealed changes in levels of three hepatic phosphoproteins following P. berghei infection compared to non-infected controls. Peptide fragment sequence analysis using tandem mass spectrometry (MS/MS) showed these hepatic proteins to be homologs to haemoglobin beta (HBB), class
Pi glutathione S-tranferase (GSTPi) and carbonic anhydrase III (CAIII) proteins of Mus musculus species respectively from the NCBInr sequence database. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis predicted the involvement of these proteins in specific pathways in Mus musculus species; GSTPi in glutathione and drug metabolism and CAIII in nitrogen metabolism. This shows that P. berghei infection affects similar signaling pathways as those reported in other pathogenic infections such as that related to GSTPi and CAIII in response to oxidative stress.

INTRODUCTION: Chronic kidney disease (CKD) usually has increase of asymmetric dimethylarginine (ADMA) levels. ADMA is a cardiovascular disease (CVD) risk factor and its elevation associated with other CVD risk factors at CKD leads to increasing risk of death. In this article, we aimed to identify levels and elevation proportion of plasma ADMA in CKD as well as association between ADMA with CVD risk factors.
METHODS: This cross-sectional study was performed at Hue Central Hospital from 2012-2016 on 176 CKD and 64 control subjects. ADMA levels were measured by using the enzyme linked immunosorbent assay (ELISA) method.
RESULTS: Mean ADMA level was markedly higher (p<0.001) in all patients combined (0.73±0.24μmol/L) than in control subjects (0.47±0.13μmol/L). Mean ADMA levels in advanced kidney disease were higher than control subjects. ADMA levels correlated inversely and relatively strictly to estimated glomerular filtration rate (eGFR) (r = -0.689; p<0.001), haemoglobin (r = -0.525; p<0.001) and haematocrit (r = - 0.491; p<0.001); correlated favourably and relatively strictly to serum creatinine (r = 0.569; p<0.001) and serum urea (r = 0.642; p<0.001). ADMA elevation was predicted simultaneously by eGFR<60 mL/min/1.73m2 (p<0.001), anaemia (p=0.002), body mass index (BMI) (p=0.011) and high sensitivity C-reactive protein (hs-CRP) (p=0.041). Cutoff of ≥0.68μmol/L, ADMA levels predict reduction of eGFR<60 mL/min/1.73m2, sensitivity of 86.9 %, specificity of 82.6%, area under ROC 92.4% (95%CI: 88.6-96.1%).

Fulltext Axillary Artery Injury with Intact Radial Pulse following Fracture-Dislocation of Shoulder: A Case Report

Rajeev A, Timmons G

Malays Orthop J, 2019 Nov;13(3):66-68.
PMID: 31890113 DOI: 10.5704/MOJ.1911.011

The occurrence of axillary artery injury following proximal humerus fracture dislocation in elderly patient with low velocity fall is uncommon. The patient could have diverse clinical presentations in spite of intact peripheral pulses. We report the case of an 85-year-old lady who presented to our emergency department with greater tuberosity fracture of the humerus with dislocation of the right shoulder. After closed manipulative reduction of the dislocation, it was observed that the patient had brachial plexus palsy with intact radial pulse. An expanding swelling and bruise around the shoulder was noted and a steady drop in haemoglobin level. CT angiogram revealed avulsion of the posterior circumflex artery which was then treated successfully with stenting.
