Treatment of distal tibia fractures: plating versus intramedullary nailing

Background: Distal tibia shaft fractures pose significant challenge to treating surgeons. Giving more importance to anatomical reduction and ignoring often injured soft tissues has led to poor outcomes and high complication rates. Although multiple options are described to treat these fractures, there is no consensus on the best method of treatment. We hereby want to study the results of distal tibia fractures treated by expert tibia nailing and distal tibia plating.Methods: This study was undertaken in patients who were operated in between January 2012 to March 2015 at M S Ramaiah Teaching Hospital, which is a tertiary care hospital in Bangalore. Study included 52 patients with distal tibia fracture treated by surgery. All the fractures were closed distal diaphyseal fractures without articular involvement. Thirty two patients underwent expert tibia nailing whereas 20 patients were treated with open reduction and internal fixation with locking plates. Patients were followed up at 6 weeks, 3 months, 6 months and 1 year.Results: Fifty two patients included in study and they were divided into two groups as nailing group and plating group. Plating group included 20 patients whereas nailing group included 32 patients. The mode of injury was  road traffic injury in 32 cases , followed by self-fall in 17 cases and sports related injury in 3 cases. Distal tibia fracture was associated with in 29 patients (87%) of nailing group whereas in 17 patients (80) of plating group. Average distance of fracture from pilon was 6 cm in nailing group and 3cm in plating group.  The average duration of surgery in nailing was  group  was 88 minutes (range, 65-130 minutes) whereas average duration of surgery in  plating group was group  was 92 minutes (range, 70-130 minutes).  The average time for union was 16 weeks for nailing group and for plating group it was 18 weeks.  Conclusions: Both intramedullary nailing and plating are the optimal methods of treatment. Plating is preferred in cases where fracture is close to pilon whereas intramedullary nailing is preferred for fractures away from tibial pilon. There is no significant difference between union and complication rates

Dynamic Response and Flutter Prediction of Structures with Unknown System Parameters using Experimental Modal Parameters

This paper presents an approach for prediction of dynamic modal transient response and flutter characteristics of structures with unknown system parameters, such as stiffness and mass, using experimental modal parameters. Correlation of the results with a finite element model created using the actual material properties of the structure was studied. Close agreement was observed for the computed transient responses and flutter velocities by the proposed method, using experimental modal parameters, for which material properties are not a pre-requisite

Extraction of manganese from Ferro-manganese slag

In the present investigation an attempt has been made to recover manganese from ferro-manganese slag of ferro-alloy plant. Roasting and leaching are the techniques used to recover- manganese. Roasting has been carried out by mixing the slag with CaO and CaCO3, at 1200Cfor 2 hours. The leaching of the roasted mass has been carried out in ferric chloride solution alone, as well as in presence of sucrose in ferric chloride solution. The optimum condit-ions have been established by varying the parameters like concentration of leaching agent, percent solids, particle size of the slag, temperature and time of leaching. It is possible to recover 87% of manganese from the ferro-manganese slag of 200# at a temperature of 80°C, 2 hours of leaching time and 5% solids in 0. 154 M ferric chloride solution. It has been found that the presence of sucrose in ferric chloride solution enhances the rate & recovery)recovery of manganese from slag

Data quality monitoring and performance metrics of a prospective, population-based observational study of maternal and newborn health in low resource settings

BACKGROUND: To describe quantitative data quality monitoring and performance metrics adopted by the Global Network´s (GN) Maternal Newborn Health Registry (MNHR), a maternal and perinatal population-based registry (MPPBR) based in low and middle income countries (LMICs). METHODS: Ongoing prospective, population-based data on all pregnancy outcomes within defined geographical locations participating in the GN have been collected since 2008. Data quality metrics were defined and are implemented at the cluster, site and the central level to ensure data quality. Quantitative performance metrics are described for data collected between 2010 and 2013. RESULTS: Delivery outcome rates over 95% illustrate that all sites are successful in following patients from pregnancy through delivery. Examples of specific performance metric reports illustrate how both the metrics and reporting process are used to identify cluster-level and site-level quality issues and illustrate how those metrics track over time. Other summary reports (e.g. the increasing proportion of measured birth weight compared to estimated and missing birth weight) illustrate how a site has improved quality over time. CONCLUSION: High quality MPPBRs such as the MNHR provide key information on pregnancy outcomes to local and international health officials where civil registration systems are lacking. The MNHR has measures in place to monitor data collection procedures and improve the quality of data collected. Sites have increasingly achieved acceptable values of performance metrics over time, indicating improvements in data quality, but the quality control program must continue to evolve to optimize the use of the MNHR to assess the impact of community interventions in research protocols in pregnancy and perinatal health.Fil: Goudar, Shivaprasad S..

Soil-site suitability evaluation for cardamom - A case study

Nineteen soil profiles representing seven soil series with sixteen mapping units were collected, described and mapped at Indian Institute of Spices Research, Cardamom Research Centre, Appangala, Madikeri, Karnataka for evaluating their suitability for cardamom cultivation. Soil and site properties such as climate, depth, slope, elevation, shade, texture, drainage, etc were compared with suitability criteria and the soils were assessed for growing cardamom. It is indicated that the well distributed rainfall of 1500-2000 mm with well drained conditions, a soil depth of more than 80 cm and 900-1200 m elevation support good crop of cardamom. The critical limit of Available Water Capacity was found to be 100 cm. Of the total area of the research station, 42 per cent area is highly suitable for cardamom cultivation. About 53 per cent of the area is moderately suitable and about 4 per cent is marginally suitable. &nbsp

A Color-Coded Tape for Uterine Height Measurement: A Tool to Identify Preterm Pregnancies in Low Resource Settings

Introduction Neonatal mortality associated with preterm birth can be reduced with antenatal corticosteroids (ACS), yet <10% of eligible pregnant women in low-middle income countries. The inability to accurately determine gestational age (GA) leads to under-identification of high-risk women who could receive ACS or other interventions. To facilitate better identification in low-resource settings, we developed a color-coded tape for uterine height (UH) measurement and estimated its accuracy identifying preterm pregnancies. Methods We designed a series of colored-coded tapes with segments corresponding to UH measurements for 20–23.6 weeks, 24.0–35.6 weeks, and >36.0 weeks GA. In phase 1, UH measurements were collected prospectively in the Democratic Republic of Congo, India and Pakistan, using distinct tapes to address variation across regions and ethnicities. In phase 2, we tested accuracy in 250 pregnant women with known GA from early ultrasound enrolled at prenatal clinics in Argentina, India, Pakistan and Zambia. Providers masked to the ultrasound GA measured UH. Receiver operating characteristics (ROC) analysis was conducted. Results 1,029 pregnant women were enrolled. In all countries the tapes were most effective identifying pregnancies between 20.0–35.6 weeks, compared to the other GAs. The ROC areas under the curves and 95% confidence intervals were: Argentina 0.69 (0.63, 0.74); Zambia 0.72 (0.66, 0.78), India 0.84 (0.80, 0.89), and Pakistan 0.83 (0.78, 0.87). The sensitivity and specificity (and 95% confidence intervals) for identifying pregnancies between 20.0–35.6 weeks, respectively, were: Argentina 87% (82%–92%) and 51% (42%–61%); Zambia 91% (86%–95%) and 50% (40%–60%); India 78% (71%–85%) and 89% (83%–94%); Pakistan 63% (55%–70%) and 94% (89%–99%). Conclusions We observed moderate-good accuracy identifying pregnancies ≤35.6 weeks gestation, with potential usefulness at the community level in low-middle income countries to facilitate the preterm identification and interventions to reduce preterm neonatal mortality. Further research is needed to validate these findings on a population basis

Evaluation of a novel device for the management of high blood pressure and shock in pregnancy in low-resource settings: study protocol for a stepped-wedge cluster-randomised controlled trial (CRADLE-3 trial).

BackgroundObstetric haemorrhage, sepsis and pregnancy hypertension account for more than 50% of maternal deaths worldwide. Early detection and effective management of these conditions relies on vital signs. The Microlife® CRADLE Vital Sign Alert (VSA) is an easy-to-use, accurate device that measures blood pressure and pulse. It incorporates a traffic-light early warning system that alerts all levels of healthcare provider to the need for escalation of care in women with obstetric haemorrhage, sepsis or pregnancy hypertension, thereby aiding early recognition of haemodynamic instability and preventing maternal mortality and morbidity. The aim of the trial was to determine whether implementation of the CRADLE intervention (the Microlife® CRADLE VSA device and CRADLE training package) into routine maternity care in place of existing equipment will reduce a composite outcome of maternal mortality and morbidity in low- and middle-income country populations.MethodsThe CRADLE-3 trial was a stepped-wedge cluster-randomised controlled trial of the CRADLE intervention compared to routine maternity care. Each cluster crossed from routine maternity care to the intervention at 2-monthly intervals over the course of 20 months (April 2016 to November 2017). All women identified as pregnant or within 6 weeks postpartum, presenting for maternity care in cluster catchment areas were eligible to participate. Primary outcome data (composite of maternal death, eclampsia and emergency hysterectomy per 10,000 deliveries) were collected at 10 clusters (Gokak, Belgaum, India; Harare, Zimbabwe; Ndola, Zambia; Lusaka, Zambia; Free Town, Sierra Leone; Mbale, Uganda; Kampala, Uganda; Cap Haitien, Haiti; South West, Malawi; Addis Ababa, Ethiopia). This trial was informed by the Medical Research Council guidance for complex interventions. A process evaluation was undertaken to evaluate implementation in each site and a cost-effectiveness evaluation will be undertaken.DiscussionAll aspects of this protocol have been evaluated in a feasibility study, with subsequent optimisation of the intervention. This trial will demonstrate the potential impact of the CRADLE intervention on reducing maternal mortality and morbidity in low-resource settings. It is anticipated that the relatively low cost of the intervention and ease of integration into existing health systems will be of significant interest to local, national and international health policy-makers.Trial registrationISCRTN41244132.

Phenolic compounds as Nrf2 inhibitors : potential applications in cancer therapy

Cancer is a leading cause of death worldwide and involves an oxidative stress mechanism. The transcription factor Nrf2 has a crucial role in cytoprotective response against oxidative stress, including cancer growth and progression and therapy resistance. For this reason, inhibitors of Nrf2 are new targets to be studied. Traditional plant-based remedies rich in phytochemicals have been used against human cancers and phenolic compounds are known for their chemopreventive properties. This comprehensive review offers an updated review of the role of phenolic compounds as anticancer agents due to their action on Nrf2 inhibition. In addition, the role of naturally-occurring bioactive anticancer agents are covered in the clinical applications of polyphenols as Nrf2 inhibitors. EkynToSR555mbd1vVCBd11Video Abstrac
