A study of risk factors of postpartum hemorrhage and indications for caesarean section

Background: To prevent post-partum hemorrhage the concept of active management of third stage of labour has been proposed which decreases the blood loss by 40-68%. The best preventive strategy is active management of the third stage of labour. The objective of the study was to study risk factors of postpartum hemorrhage and indications for caesarean section.Methods: A hospital based cross sectional study was carried out among 100 women at term for a period of one year. Pregnant women who are at term i.e. at 38-39 weeks of gestation were included in the study. Detailed history, clinical examination and investigations were carried out.Results: The mean pre pregnancy BMI in study group was 22.4±3.96. The majority of patients recruited were primiparous. Socio-demographic data shows that there was no statistical difference in place of residence, occupation and level of literacy between two groups. The prevalence of anemia among women at term was found to be 43%. The most common obstetric high risk factor was gestational diabetes mellitus in 10% followed by gestational hypertension in (6%). 71% of women underwent the emergency LSCS. The most common indication for LSCS was fetal distress in 29% of cases followed by mal-presentation in 12% of cases.Conclusions: The prevalence of anemia among women at term was found to be 43%. The different medical high risk factors were human immunodeficiency virus positive (asymptomatic diagnosed during pregnancy), Hepatitis B antigen positive, cardiovascular risk, hypothyroidism, epilepsy observed in the groups. Other high risk factors included asthma, Crohns disease, and systemic sclerosis

Efficacy of prophylactic tranexamic acid in reducing blood loss during and after caesarean section

Background: In India, caesarean section rate is rising, so the impact of prophylactic injection of tranexamic acid in decreasing blood loss during caesarean section would be more beneficial in terms of having minimal blood loss intra operatively and post operatively and thereby decreasing maternal morbidity. The objective of the study was to evaluate the efficacy of prophylactic tranexamic acid in reducing blood loss during and after caesarean section.Methods: A randomized controlled trial among 200 term women with singleton pregnancy for a period of 2 years was carried out. They were randomized by computer generated numbers into two groups: study group-100 women receiving prophylactic tranexamic acid women and control group-100 women receiving placebo.Results: The blood loss during caesarean section was less in the tranexamic acid group compared to the placebo group. Similarly blood loss measured 6hrs after caesarean section was less in the tranexamic acid group compared to placebo group. 20-40min before the time of incision was the ideal time gap for administering the injection tranexamic acid for its optimum efficacy. Tranexamic acid group had lesser requirement of uterotonic when compared to placebo, but need for blood transfusion was similar in both the groups. Greater fall in the hemoglobin and haematocrit occurred in placebo group compared to tranexamic acid group. No changes in the post-operative vitals or side effects were seen in the tranexamic acid group. Even no change in birth weight and Apgar scores was seen in neonates of tranexamic acid group.Conclusions: Injection tranexamic acid is the, antifibrinolytic agent that can be used for prophylactic administration before caesarean section for decreasing blood loss during surgery

Quantitative analysis of Amoxicillin and Dicloxacillin in Combined Dosage Form by First Derivative and Simultaneous Equation Method in Application to the determination of Content Uniformity

Two simple, accurate and precise spectrophotometric methods have been developed for the simultaneous estimation of Amoxicillin and Dicloxacillin. Method A was quantitative determination of Amoxicillin and Dicloxacillin by First Order Derivative zero crossing method. The first order derivative absorption at 231.02 nm (zero cross point of Dicloxacillin) was used for Amoxicillin and 246.26nm (zero cross point of Amoxicillin) for Dicloxacillin. Both the drugs obeyed the limit 15-35g/ml (correlation coefficient r 2 1). No interference was found between the both determined constituents and those of matrix. Method B was developed for estimation of content uniformity of Amoxicillin and Dicloxaciliin in its combined tablet dosage form. The method involves solving the simultaneous equation using 245nm and 227nm as two wavelengths for Amoxicillin and Dicloxacillin respectively. From the results, it was concluded that all brands are within the limits of content uniformity (85-115%). 0.1 N sodium hydroxide was used as a solvent for both methods. Developed method was employed to determine the Amoxicillin and Dicloxacillin content in ten individual capsule units of four marketed formulations. Both the methods were validated statistically and recovery studies were carried out to confirm the accuracy of the methods

Assessment of dynamic balance and bone density in premenopausal and postmenopausal middle-age women: a comparative study

Background: Dynamic balance control is required to perform simple and complex mobility task in our day-to-day life. Deficit in balance can results in falls and fractures which can affect health-related quality of life. Menopause is also considered as a risk for fracture due to osteoporosis, which at later life becomes difficult to manage and causes higher morbidity. So, evaluation of balance and bone density is important in middle-age in women, so that we can plan and administer proper treatment strategies at an early stage which can reduce risk of falls and fractures. Therefore, the aim of the study was to assess and compare dynamic balance and bone density in premenopausal and postmenopausal middle-age women.Methods: Female participants in the age-group of 40-60 years were divided into premenopausal and postmenopausal group based on the criteria of cessation of menstrual cycles for minimum one year. Participants were assessed barefooted for dynamic balance by physical performance mobility tests such as narrow walk test (NWT), Figure-of-8 walk test (F8WT), obstacle walk test (OWT) and normal gait speed (NGS). Bone density was evaluated by using ultrasound bone densitometer at calcaneus in community setting. Results: The time taken to complete the NWT, F8WT, OWT was reduced significantly (p<0.05) in post-menopausal group, showing dynamic balance is significantly affected in postmenopausal women when compared with premenopausal women in middle-age group. Gait speed was also reduced in both the groups but it was significantly reduced (p<0.05) in postmenopausal group. Also bone density decreases significantly in post-menopausal group showing osteoporosis, premenopausal group also showed osteopenia when assessed by ultrasound bone densitometer in community setting.Conclusions: Dynamic balance and bone density significantly decreases in post-menopausal middle-age women as compared with pre-menopausal middle-age women

The hemostatic activity of Manilkara zapota (L.) P. Royen latex associated with fibrinogenolytic activity

Manilkara zapota (L.) P. Royen (Sapotaceae), is widely used in traditional medicine for various ailments like, diarrhea, pulmonary diseases, piles, ulcers and to treat wounds. The present study evaluates the role of M. zapota latex in hemostasis. The processed latex named as M. zapota natant latex (MzNL), has proteins at the concentration of 8 mg/ml and showed protein bands in Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The proteolytic activity of MzNL was evaluated using casein in comparison with trypsin. The phenylmethylsulfonyl fluoride (PMSF) inhibited the protease activity indicating the possible presence of serine protease. The effect of temperature, pH and metal ions on proteolytic activity was evaluated. MzNL exhibited fibrinogenolytic activity by hydrolysing A? and B? subunits of fibrinogen. However, ? subunit remained resistant for hydrolysis. MzNL hydrolyzed all the subunits of collagen type I and IV at the concentration of 8 µg and 25 µg in 20 µl each respectively. MzNL showed procoagulant activity and is devoid of hemolytic activity. Fibrinogenolytic activity and procoagulant nature of MzNL suggests its possible role in blood coagulation that in turn restores hemostasis

A Randomized Comparative Clinical Study to evaluate the effect of Bodhi Vruksha Twak Kashaya with Madhu and Guduchi Kashaya in the Management of Vatarakta with special reference to Gouty Arthritis

Background: Vatarakta is a disease which is said to affect the population indulging in sedentary lifestyle. In today’s era the evolution of technology has reached a point where pretty much anything is available at the touch of a button. The lifestyle of today’s population is breeding ground for diseases like Vatarakta. Based on the causes, signs and symptoms, Vatarakta may be correlated to gouty arthritis in contemporary medicine. Gout affects about 2.1 million worldwide. Its prevalence is increasing; moreover it is a potential signal for unrecognized co-morbidities like obesity, diabetes mellitus, hypertension and renal diseases. In India the prevalence of gout is 2-6 per 1000. The purpose of this study is to explore and find out an effective, less expensive, easily available and well accepted drug with minimal or no complications for this dreadful condition.

Observations and Results: In the present study Group A showed statistical significant results in all the parameters except for Sandhishotha and group B showed statistical significant result in Sandhishoola, Sandhidaha, Sparshasahaishnuta and uric acid levels. Conclusion: Overall result shows patients treated with Guduchi Kashaya showed better results than patients treated with Bodhi Vruksha Twak Kashaya with Madhu in Vatarakta with special reference to Gouty Arthritis

Optimization of ohmic contact for AlGaN/ GaN HEMT on low resistivity silicon

In this article, we report the optimization of ohmic contact formation on AlGaN/GaN on low-resistivity silicon. For achieving this, a strategy of uneven AlGaN/GaN was introduced through patterned etching of the substrate under the contact. Various pattern designs (holes, horizontal lines, vertical lines, grid) and varied etch depth (above and below the 2-D electron gas) were investigated. Furthermore, a study of planar and nonplanar ohmic metallization was investigated. Compared to a traditional fabrication strategy, we observed a reduced contact resistance from 0.35 to 0.27 Ω · mm by employing a grid etching approach with a “below channel” etch depth and nonplanar ohmic metallization. In general, measurements of “below channel” test structures exhibited improved contact resistance compared to “above channel” in both planar and nonplanar ohmic metallizatio

Whole genome expression and biochemical correlates of extreme constitutional types defined in Ayurveda

<p>Abstract</p> <p>Background</p> <p>Ayurveda is an ancient system of personalized medicine documented and practiced in India since 1500 B.C. According to this system an individual's basic constitution to a large extent determines predisposition and prognosis to diseases as well as therapy and life-style regime. Ayurveda describes seven broad constitution types (<it>Prakriti</it>s) each with a varying degree of predisposition to different diseases. Amongst these, three most contrasting types, <it>Vata</it>, <it>Pitta</it>, <it>Kapha</it>, are the most vulnerable to diseases. In the realm of modern predictive medicine, efforts are being directed towards capturing disease phenotypes with greater precision for successful identification of markers for prospective disease conditions. In this study, we explore whether the different constitution types as described in Ayurveda has molecular correlates.</p> <p>Methods</p> <p>Normal individuals of the three most contrasting constitutional types were identified following phenotyping criteria described in Ayurveda in Indian population of Indo-European origin. The peripheral blood samples of these individuals were analysed for genome wide expression levels, biochemical and hematological parameters. Gene Ontology (GO) and pathway based analysis was carried out on differentially expressed genes to explore if there were significant enrichments of functional categories among <it>Prakriti </it>types.</p> <p>Results</p> <p>Individuals from the three most contrasting constitutional types exhibit striking differences with respect to biochemical and hematological parameters and at genome wide expression levels. Biochemical profiles like liver function tests, lipid profiles, and hematological parameters like haemoglobin exhibited differences between <it>Prakriti </it>types. Functional categories of genes showing differential expression among <it>Prakriti </it>types were significantly enriched in core biological processes like transport, regulation of cyclin dependent protein kinase activity, immune response and regulation of blood coagulation. A significant enrichment of housekeeping, disease related and hub genes were observed in these extreme constitution types.</p> <p>Conclusion</p> <p>Ayurveda based method of phenotypic classification of extreme constitutional types allows us to uncover genes that may contribute to system level differences in normal individuals which could lead to differential disease predisposition. This is a first attempt towards unraveling the clinical phenotyping principle of a traditional system of medicine in terms of modern biology. An integration of Ayurveda with genomics holds potential and promise for future predictive medicine.</p
