Chemistry by Mobile Phone (or how to justify more time at the bar)

By combining automatic environment monitoring with Java smartphones a system has been produced for the real-time monitoring of experiments whilst away from the lab. Changes in the laboratory environment are encapsulated as simple XML messages, which are published using an MQTT compliant broker. Clients subscribe to the MQTT stream, and produce a user display. An MQTT client written for the Java MIDP platform, can be run on a smartphone with a GPRS Internet connection, freeing us from the constraints of the lab. We present an overview of the technologies used, and how these are helping chemists make the best use of their time

Assessment of clinical practice guideline methodology for the treatment of knee osteoarthritis with intra-articular hyaluronic acid

© 2015 The Authors. Published by Elsevier HS Journals ,Inc. Introduction: Clinical practice guidelines are of increasing importance in the decision making for the treatment of knee osteoarthritis. Inconsistent recommendations regarding the use of intra-articular hyaluronic acid for the treatment of knee osteoarthritis have led to confusion among treating physicians. Methods: Literature search to identify clinical practice guidelines that provide recommendations regarding the use of intra-articular hyaluronic acid treatment for knee osteoarthritis was conducted. Included guidelines were appraised using the AGREE II instrument. Guideline development methodologies, how the results were assessed, the recommendation formation, and work group composition were summarized. Results: Overall, 10 clinical practice guidelines were identified that met our inclusion criteria. AGREE II domain scores were variable across the included guidelines. The methodology utilized across the guidelines was heterogeneous regarding the evidence inclusion criteria, analysis of evidence results, formulation of clinical practice recommendations, and work group composition. The recommendations provided by the guidelines for intra-articular hyaluronic acid treatment for knee osteoarthritis are highly inconsistent as a result of the variability in guideline methodology. Overall, 30% of the included guidelines recommended against the use of intra-articular hyaluronic acid in the treatment of knee osteoarthritis, while 30% deemed the treatment an appropriate intervention under certain scenarios. The remaining 40% of the guidelines provided either an uncertain recommendation or no recommendation at all, based on the high variability in reviewed evidence regarding efficacy and trial quality. Conclusion: There is a need for a standard appropriate methodology that is agreed upon for osteoarthritis clinical practice guidelines in order to prevent the development of conflicting recommendations for intra-articular hyaluronic acid treatment for knee osteoarthritis, and to assure that treating physicians who are utilizing these guidelines are making their clinical decisions on the best available evidence. At present, the inconsistent recommendations provided for intra-articular hyaluronic acid treatment make it difficult for clinical professionals to determine its appropriateness when treating patients with knee osteoarthritis

NONTHERMAL EFFECTS OF MOBILE PHONE RADIATIONS ON HUMAN HEART RATE, BLOOD PRESSURE, AND SUGAR LEVEL

Objective: A single-blinded pilot study has been conducted to investigate the effect of cell phone radiation on the human heart. Methods: Experimental work has been conducted in Jalandhar-based hospital under the supervision of a cardiologist. During experimental work, electrocardiogram (ECG), blood pressure (BP) level, and sugar level have been examined before and after cell phone radiation exposure. For ECG analysis, the parameters such as heart rate, rhythm, mechanism, axis, P wave, PR interval, QRS complex, ST segment, T wave, and QT interval have been examined in the study.Results: No significant variations in the results of above-mentioned parameter has been observed before and after acute exposure of cell phones radiations by placing cell phone closer to heart.Conclusion: The result of this study concludes that mobile phone radiations do not interfere with any electrical activity of the human heart, BP, and sugar level in healthy individuals

Comparative evaluation of machine learning models for groundwater quality assessment

Contamination from pesticides and nitrate in groundwater is a significant threat to water quality in general and agriculturally intensive regions in particular. Three widely used machine learning models, namely, artificial neural networks (ANN), support vector machines (SVM), and extreme gradient boosting (XGB), were evaluated for their efficacy in predicting contamination levels using sparse data with non-linear relationships. The predictive ability of the models was assessed using a dataset consisting of 303 wells across 12 Midwestern states in the USA. Multiple hydrogeologic, water quality, and land use features were chosen as the independent variables, and classes were based on measured concentration ranges of nitrate and pesticide. This study evaluates the classification performance of the models for two, three, and four class scenarios and compares them with the corresponding regression models. The study also examines the issue of class imbalance and tests the efficacy of three class imbalance mitigation techniques: oversampling, weighting, and oversampling and weighting, for all the scenarios. The models’ performance is reported using multiple metrics, both insensitive to class imbalance (accuracy) and sensitive to class imbalance (F1 score and MCC). Finally, the study assesses the importance of features using game-theoretic Shapley values to rank features consistently and offer model interpretability

Does community-based health insurance affect lifestyle and timing of treatment seeking behavior?:Evidence from Ethiopia

Objectives: This paper aims to investigate the effects of enrollment in the Ethiopian community-based health insurance (CBHI) scheme on household preventive care activities and the timing of treatment-seeking behavior for illness symptoms. There is growing concern about the financial sustainability of CBHI schemes in developing countries. However, few empirical studies have identified potential contributors, including ex-ante and ex-post moral hazards. Methods: We implement a household fixed-effect panel data regression model, drawing on three rounds of household survey data collected face to face in districts where CBHI scheme is operational and in districts where it is not operational in Ethiopia. Results: The findings show that enrolment in CBHI does not significantly influence household behaviour regarding preventive care activities such as water treatment before drinking and handwashing before meals. However, CBHI significantly increases delay in treatment-seeking behaviour for diseases symptoms. Particularly, on average, we estimate about 4‒6 h delay for malaria symptoms, a little above 4 h for tetanus, and 10‒11 h for tuberculosis among the insured households. Conclusions: While there is evidence that CBHI improve the utilization of outpatient or primary care services, our study suggests that insured members may wait longer before visiting health facilities. This delay could be partly due to moral hazard problems, as insured households, particularly those from rural areas, may consider the opportunity costs associated with visiting health facilities for minor symptoms. Overall, it is essential to identify the primary causes of delays in seeking medical services and implement appropriate interventions to encourage insured individuals to seek early medical attention.</p
