Background: Observational epidemiological studies and a systematic review have consistently shown an association between maternal exposure to biomass smoke and reduced birth weight. Our aim was to further test this hypothesis. Methods. We analysed the data from 47,139 most recent singleton births during preceding five years of 2005-06 India Demographic Health Survey (DHS). Information about birth weight from child health card and/or mothers' recall) was analysed. Since birth weight was not recorded for nearly 60% of the reported births, maternal self-report of child's size at birth was used as a proxy. Fuel type was classified as high pollution fuels (wood, straw, animal dung, and crop residues kerosene, coal and charcoal), and low pollution fuels (electricity, liquid petroleum gas (LPG), natural gas and biogas). Univariate and multivariable logistic regression models were developed using SURVEYLOGISTIC procedure in SAS system. We used three logistic regression models in which child factors, maternal factors and demographic factors were added step-by-step to the main exposure variable. Adjusted Odds Ratios (AORs) and their 95% CI were calculated. A p-value less than 0.05 was considered as significant. Results: Child's birth weight was available for only 19,270 (41%) births; 3113 from health card and 16,157 from mothers' recall. For available data, mean birth weight was 2846.5 grams (SD = 684.6). Children born in households using high pollution fuels were 73 grams lighter than those born in households using low pollution fuels (mean birth weight 2883.8 grams versus 2810.7 grams, p < 0.001). Use of biomass fuels was associated with size at birth. Unadjusted OR was 1.41 (95% CI, 1.27 1.55). Adjusted OR after controlling for child factors was 1.41 (95% CI 1.29, 1.57). AOR after controlling for both child and maternal factors was 1.21 (95% CI 1.06, 1.32). In final model AOR was 1.07 (95% 0.94, 1.22) after controlling for child, maternal and demographic factors. Gender, birth order, mother's BMI, haemoglobin level and education were significant in all three models. Conclusions: Use of biomass fuels is associated with child size at birth. Future studies should investigate this association using more direct methods for measurement of exposure to smoke emitted from biomass fuels and birth weight. © 2011 Sreeramareddy et al; licensee BioMed Central Ltd.

After the concept of evidence based medicine it became important all over the world to have more structured, clinical oriented curriculum. According to the United Nations, Asia is divided into five sub regions. Brunei, Cambodia, East Timor, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam belong to South-eastern Asia. To cope with the rapid changes in medical education curriculum most of the medical school in Asia particularly south East Asian countries adopted took up curriculum to fit to the current need. Medical education in Malaysia and Singapore developed similarly as the two countries together formed a federation in the British Empire until independence in 1957. Currently, in medical education, a trend has emerged to utilize "trustable research findings" in place of "personal opinions" as a basis for educational management and decision-making. Several of Malaysia's medical schools partner with other European, American and Asian schools, and students sometimes earn the certification or accreditation to practice in those countries as well. In the context of changing medical education system, South East Asia is also adopting up to date medical curriculum for the medical students in these countries. As a result rapid changes in curriculum with special focus on research these schools likely to become a hub of 'educational tourist'.

Congenital bleeding disorders can cause obstetric haemorrhage during pregnancy, labour and following delivery. Desmopressin acetate is found to be an effective drug which can reduce the risk of haemorrhage and can also stop bleeding in certain congenital bleeding disorders. Its use in pregnancy has been controversial. Hence beneficial and adverse effects of desmopressin acetate in these groups of pregnant women should be evaluated. To determine the efficacy of desmopressin acetate in preventing and treating acute bleeds during pregnancy in women with congenital bleeding disorders. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coaguopathies Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant and abstract books of conferences proceedings. We also searched for any randomised controlled trials in a registry of ongoing trials and the reference lists of relevant articles and reviews.Date of most recent search: 28 February 2013. Randomised and quasi-randomised controlled trials investigating the efficacy of desmopressin acetate versus tranexamic acid or factor VIII or rFactor VII or fresh frozen plasma in preventing and treating congenital bleeding disorders during pregnancy were eligible. No trials matching the selection criteria were eligible for inclusion. No trials matching the selection criteria were eligible for inclusion. The review did not identify any randomised controlled trials investigating the relative effectiveness of desmopressin acetate for bleeding during pregnancy in women with congenital bleeding disorders. In the absence of high quality evidence, clinicians need to use their clinical judgement and lower level evidence (e.g. from observational trials) to decide whether or not to treat women with congenital bleeding disorders with desmopressin acetate.Given the ethical considerations, future randomised controlled trials are unlikely. However, other high quality controlled studies (such as risk allocation designs, sequential design, parallel cohort design) to investigate the risks and benefits of using desmopressin acetate in this population are needed.

During pregnancy, a Rhesus-negative (Rh-negative) woman may develop antibodies if her fetus is Rh-positive, which can cause fetal morbidity or mortality in following pregnancies, if untreated. To assess the effects of administering anti-D immunoglobulin (Ig) after spontaneous miscarriage in a Rh-negative woman, with no anti-D antibodies. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 December 2012). Randomised controlled trials (RCT) in Rh-negative women without antibodies who were given anti-D Ig following spontaneous miscarriage compared with no treatment or placebo treatment following spontaneous miscarriage as control. Two review authors independently assessed trials for inclusion and trial quality. Two review authors extracted data and checked it for accuracy. We included one RCT, involving 48 women who had a miscarriage between eight to 24 weeks of gestation. Of the 19 women in the treatment group, 14 had therapeutic dilatation & curettage (D&C) and five had spontaneous miscarriage; of the 29 women in the control group, 25 had therapeutic D&C and four had spontaneous miscarriage. The treatment group received 300 μg anti-D Ig intramuscular injection and were compared with a control group who received 1 cc homogenous gamma globulin placebo.This review's primary outcomes (development of a positive Kleihauer Betke test (a test that detects fetal cells in the maternal blood; and development of RhD alloimmunisation in a subsequent pregnancy) were not reported in the included study.Similarly, none of the review's secondary outcomes were reported in the included study: the need for increased surveillance for suspected fetal blood sampling and fetal transfusions in subsequent pregnancies, neonatal morbidity such as neonatal anaemia, jaundice, bilirubin encephalopathy, erythroblastosis, prematurity, hypoglycaemia (low blood sugar) in subsequent pregnancies, maternal adverse events of anti-D administration including anaphylactic reaction and blood-borne infections.The included study did report subsequent Rh-positive pregnancies in three women in the treatment group and six women in the control group. However, due to the small sample size, the study failed to show any difference in maternal sensitisation or development of Rh alloimmunisation in the subsequent pregnancies. There are insufficient data available to evaluate the practice of anti-D administration in an unsensitised Rh-negative mother after spontaneous miscarriage. Thus, until high-quality evidence becomes available, the practice of anti-D Immunoglobulin prophylaxis after spontaneous miscarriage for preventing Rh alloimmunisation cannot be generalised and should be based on the standard practice guidelines of each country.

Restless legs syndrome (RLS) is a common sensory motor neurological disorder that is characterised by an irresistible urge to move the legs that significantly affects the quality of life of the patient. Prevalence in the general population is 5-25% and it is twice as prevalent in women as in men. RLS is the most common movement disorder in pregnancy with a fourfold increased risk of developing this disorder later in life. The pathophysiology of RLS is centred on dopaminergic dysfunction, reduced central nervous system iron, genetic linkages, or alteration in neurotransmitters such as hypocretins, endorphins levels and immune dysfunction and inflammatory mechanisms. With the emergence of new evidence, there are changes to the previous treatment recommendations for RLS. There is sufficient evidence to conclude that dopamine agonists such as rotigotine transdermal patch, pramipexole, ropinirole, gabapentin enacarbil, pregabalin and gabapentin are effective in the short-term treatment of RLS and rotigotine, followed by gabapentin enacarbil, ropinirole, pramipexole and gabapentin for long-term treatment. Based on expert consensus, the recommendation for daily RLS is dopamine agonists or gabapentin or low-potency opioids. Levodopa is less preferred for treating daily RLS due to its high risk of augmentation. For intermittent RLS, it is levodopa or dopamine agonists or low-potency opioids or benzodiazepines. For refractory RLS, the choice is to change to gabapentin or a different dopamine agonist, addition of a second agent like gabapentin or benzodiazepine to the existing drug or changing to a high-potency opioid or tramadol. Medications with safety record in pregnancy include opioids and antiepileptics such as carbamazepine and gabapentin. There are concerns that patients with RLS are at risk for metabolic deregulation, autonomic dysfunction and cardiovascular morbidity. However, a recent study concluded that RLS is not associated with increased risk of cardiovascular complications.

Adenosine receptors are major targets of caffeine, the most commonly consumed drug in the world. There is growing evidence that they could also be promising therapeutic targets in a wide range of conditions, including cerebral and cardiac ischaemic diseases, sleep disorders, immune and inflammatory disorders and cancer. After more than three decades of medicinal chemistry research, a considerable number of selective agonists and antagonists of adenosine receptors have been discovered, and some have been clinically evaluated, although none has yet received regulatory approval. However, recent advances in the understanding of the roles of the various adenosine receptor subtypes, and in the development of selective and potent ligands, as discussed in this review, have brought the goal of therapeutic application of adenosine receptor modulators considerably closer.

Sirtuins are evolutionary conserved NAD+ dependent acetyl-lysine deacetylases and ADP ribosyltransferases dual-function enzymes involved in the regulation of metabolism and lifespan. Sirtuins represent a promising new class of III NAD dependent histone deacetylases that regulate a number of physiological processes, originally identified in yeast. Sirtuins regulate various normal and abnormal cellular and metabolic processes, including tumorgenesis, neurodegeneration and processes associated with type 2 diabetes and obesity. Several age-related diseases such as Alzheimer's disease and longevity have also been linked to the functions of sirtuins. Because of these associations, the identification of small molecules sirtuin modulators has been of significant interest.

Charcot neuroarthropathy (CN) is a rare, progressive, deforming disease of bone and joints, especially affecting the foot and ankle and leading to considerable morbidity. It can also affect other joints such as the wrist, knee, spine and shoulder. This disease, described originally in reference to syphilis, is now one of the most common associates of diabetes mellitus. As the number of diabetics increase, the incidence of CN is bound to rise. Faster initial diagnosis and prompt institution of treatment may help to reduce its sequelae. There should be a low threshold for ordering investigations to assist coming to this diagnosis. No single investigation is the gold standard. Recent studies on pathogenesis and development of newer investigation modalities have helped to clarify the mystery of its pathogenesis and of its diagnosis in the acute phase. Various complementary investigations together allow the correct diagnosis to be made. Osteomyelitis continues to be confused with acute CN. Hybrid positron emission tomography has shown some promise in differentiating these conditions. A multispecialty approach involving diabetologists, orthopaedists and podiatrists should be used to tackle this difficult problem. The aim of this article is to describe current knowledge about CN with particular reference to the status of diagnostic indicators and management options. © 2013 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

Simulation in Healthcare | Year: 2014

SUMMARY STATEMENT: Arthroscopy uses a completely different skill set compared with open orthopedic surgery. Hitherto, arthroscopy had not been given enough emphasis in the core orthopedic curricula. Simulation has been seen as an excellent way to teach the skills required in arthroscopy. The simulators used for arthroscopy training can be broadly classified into physical simulators such as cadavers, animals, models and box trainers, virtual-reality simulators, and hybrid simulators that combine virtual-reality simulation with physical components that allow real tactile feedback. The advantages and disadvantages of each of these types have been described in this article. The factors that determine skill acquisition using these simulators have been highlighted. In conclusion, simulation seems to be a valuable tool for arthroscopy training, although further studies are needed to state whether this translates into better operative skill on real patients.Copyright © 2014 Society for Simulation in Healthcare.

Background: Heart Rate Variability (HRV) analysis is easy to perform, has good reproducibility and provides prognostic information about Coronary Heart Disease. Objective: This work was devised to correlate exercise induced HRV with BMI and compare gender variability among healthy Indian children aged 13-20 years. Methods: The Heart Rate Variability of sixty-five students in the 13-20 years age group was assessed by time-domain methods during resting and after exercise. On the basis of BMI, the subjects were grouped into T1 group (BMI<18) and T2 group (≥18). The HRV of these groups were analyzed. In addition, based on gender, male students were divided on the basis of BMI as follows: M1 group <18 and M2 group ≥ 18. Likewise females were grouped into F1 and F2 groups. The HRV of 3 male groups and 3 female groups were also separately analysed. A paired t- test was used for the dependent variables and an unpaired t-test was carried out for normally distributed variables using Statistical Package for Social Sciences (SPSS) 11.0 for windows. Results: Females showed higher HRV than males during resting condition. But immediately after exercise, the HRV increased in all groups and there was no difference in HRV based on gender and BMI. When recorded 5 minutes after exercise, the HRV decreased further regardless of gender and BMI. However, the HRV taken 30 minutes after exercise behaved more like the resting condition. The HRV recorded 30 minutes after exercise increased from the "5 minutes after exercise" value but still remained lower in all groups regardless of gender and BMI. Conclusions: The results demonstrate that, in healthy adolescents, the parasympathetic activity is higher in females than in males during the rest period. Exercise induced sympathetic activity lasts longer in females with higher BMI and lower age, resulting in decreased HRV.
