The effect of education based on Leventhal's model on adherence to treatment and control of blood pressure in patients with hypertension

Background & Aim: Hypertension is a prevalent and significant health problem; moreover, lack of treatment adherence can cause precarious complications. The present study aims to determine the effect of education based on Leventhal's model on adherence to treatment and control of blood pressure in patients with hypertension. Methods & Materials: This quasi-experimental study was performed on 59 patients with hypertension in Gonabad in 2020. The participants were selected based on convenience sampling; they were randomly assigned to the intervention and control groups. In addition to the routine treatment for hypertension, the patients in the intervention group received a training program based on Leventhal's model in 45-minute sessions and three times a week. In contrast, the patients in the control group received only the routine treatment for hypertension. A demographic and Hill-Bone Adherence Questionnaires were completed for the participants. Moreover, their blood pressure was recorded using the blood pressure record form. The data were analyzed in SPSS v.22 software, at the significance level of p<0.05. Results: The two groups were homogeneous in adherence to treatment (P=0.63) before the intervention; yet, there was a substantial difference between the groups once the intervention was implemented (P<0.001). Besides, the average systolic and diastolic blood pressure was not significantly different between the two groups before the intervention. After the intervention, though, the difference was reported significant (p<0.05). Conclusion: Education based on Leventhal's model caused an improvement in adherence to treatment and reduced blood pressure among patients with hypertension.

Materials (II)

This chapter describes the properties of a number of interesting superconducting materials. The study of phonon-mediated superconductors, such as A-15 materials and MgB2, flourished after the discovery of the high-Tc hydrides. At present, this family displays, under high pressure, record values of Tc close to room temperature. Other interesting systems, such as pnictides, heavy fermions, and ruthenates, with their peculiar interplay of superconductivity and magnetism, are also described. Fe-based superconductors, which were recently discovered, have relatively high Tc at ambient pressure. They display a two-gap energy spectrum. Pairing in intercalated nitrides is mainly provided by acoustic plasmons. Tungsten oxides represent a new family of oxides containing elements other than copper; they form filamentary structures. A special class is formed by topological superconductors; usually their properties are caused by odd-parity pairing. The presence of the states inside of the energy gap make these superconductors similar to topological insulators.

Technical note: Disentangling the groundwater response to Earth and atmospheric tides to improve subsurface characterisation

The groundwater response to Earth tides and atmospheric pressure changes can be used to understand subsurface processes and estimate hydraulic and hydro-mechanical properties. We develop a generalised frequency domain approach to disentangle the impacts of Earth and atmospheric tides on groundwater level responses. By considering the complex harmonic properties of the signal, we improve upon a previous method for quantifying barometric efficiency (BE), while simultaneously assessing system confinement and estimating hydraulic conductivity and specific storage. We demonstrate and validate this novel approach using an example barometric and groundwater pressure record with strong Earth tide influences. Our method enables improved and rapid assessment of subsurface processes and properties using standard pressure measurements.

Sound signals of tsunamis from a slender fault

Since the speed of sound in water is much greater than that of the surface gravity waves, acoustic signals can be used for early warning of tsunamis. We simplify existing works by treating the sound wave alone without the much slower gravity wave, and derive a two-dimensional theory for signals emanating from a fault of finite length. Under the assumptions of a slender fault and constant sea depth, the asymptotic technique of multiple scales is applied to obtain analytical results. The modal envelopes of the two-dimensional sound waves are found to be governed by the Schrödinger equation and are solved explicitly. An approximate method is described for the inverse estimation of fault properties from the pressure record at a distant hydrophone.

SURVEY ON DESIGN OF PATIENT BLOOD PRESSURE MONITORING SYSTEM USING SECURE IOT

Blood Pressure Monitoring using sensor and cloud technology, Personal biological readings such as blood pressure are collected by sensor networks device from patients at homes and will be transmitted to cloud and get treated accordingly. It is very important that privacy of patient’s medical condition is protected while data are being transmitted over the public network as well as when they are stored in servers. In this paper, a unique Cryptography technique has been used, Cryptography allows privacy of data that is transmitted. This will ensure that it is implemented for small foot print using IOT for secure data transmission. While data is transmitting to cloud Doctor will get email/message notification and Doctor can also view the Patient Blood Pressure Record stored in cloud.
