OCLC Number/Unique Identifier: 7286356007

Thermal stress of a continuous rigid frame bridge, based on the temperature gradient in Chinese bridge gauge, using a finite element analysis (FEA) method was investigated. First of all, the temperature effect of the whole bridge was analyzed, and the correlation of the improved amplitude of temperature gradient and temperature effect were studied. It was found that there was a linear relationship with temperature stress and improved temperature. And then, the temperature effect of zero block was analyzed and the details of box girder temperature stress distribution investigated by utilizing the FEA method. It was concluded that temperature stress mainly distributed in the body surface; under the condition of the improvement of temperature field, the center temperature stress of zero block was improved about 60% and the end temperature stress of zero block was improved about 75%.

Removal of Chromium from Aqueous Solution by Thermally Treated Mgal Layered Double Hydroxide

Published on: 11th January, 2017

OCLC Number/Unique Identifier: 7286428770

MgAl based layered double hydroxide (MgAl-LDH) was used as adsorbent for the removal of chromium oxyanion from an aqueous solution. MgAl-LDH was synthesized successfully using co-precipitation method, and was characterized by X-Ray Diffractometer (XRD), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). MgAl-LDH was thermally treated for improving the chromium adsorption. Samples were treated at 220°C and 450°C. A negligible difference of total chromium adsorption capacities was observed between MgAl-LDH000 and MgAl-LDH220 as 12.56 mg/g and 11.01 mg/g. The maximum chromium adsorption capacity of MgAl-LDH was 88.07 mg/g at 500g/l chromium concentration for MgAl-LDH which has been thermally treated at 450°C (MgAl-LDH450). The results indicated that memory effects of thermally treated MgAl-LDH at certain temperatures were retained and enhanced chromium removal efficiency.

Association between obesity profile and non-alcoholic fatty liver by race/ethnicity

Published on: 19th January, 2021

OCLC Number/Unique Identifier: 8897963456

NAFLD is characterized by accumulation of fat in the liver that can lead to health complications. Previous studies have found the obesity phenotype and its components to be risk factors for the development of NAFLD. This study aims to examine the relationship between the obesity phenotype and NAFLD among each racial-ethnic group. We analyzed data from the NHANES III survey (1988-1994). The obesity phenotype was defined based on BMI and metabolic syndrome. NAFLD was defined by abdominal ultrasounds among non-alcoholics with no infection or taking drugs affecting the liver. A higher prevalence of NAFLD was found among the metabolically unhealthy obese group (43.1%) and the metabolically unhealthy overweight (29.4%) than the metabolically unhealthy normal weight (11.8%). Mexicans-Americans had higher odds of NAFLD relative to whites (adjusted odds ratio (AOR) = 1.3, 95% confidence interval (CI) = 1.01-1.9, p = 0.04). The metabolically healthy obese phenotype was associated with NAFLD (p > 0.05) in the overall sample and in Whites. The metabolically healthy overweight was associated with NAFLD only among Mexican-American (p < 0.05). Metabolically unhealthy overweight or obese had higher odds of NAFLD relative to the metabolically healthy normal weight and this relation is consistent in all the racial/ethnic groups (p < 0.05). Metabolically healthy overweight and obese individuals had a high chance of NAFLD and it varied by race/ethnicity. Healthcare providers should pay more attention to care for those who are part of the metabolically healthy overweight or obese group especially among the Mexican-American population.

COVID-19 associated hyperthyroidism due to destructive thyrotoxicosis in a young female patient

Published on: 27th July, 2020

OCLC Number/Unique Identifier: 8643729535

SARS-CoV2 can induce multiple immunological and endocrinological changes. We report the case of a COVID-19 associated hyperthyroidism in a young female. Per definition the patient – because of having given birth six weeks previously - had a postpartum thyroiditis. However thus no antibodies were detected, the thyroiditis ceased without medication after the dissolving of the virus disease and the fT3/fT3-ratio proved a destructive thyreopathy as well as there was a close time link onset of the symptoms with the novel corona virus infection we argue it to be a COVID-19 induced thyrotoxicosis. This proves the ability of SARS-CoV-2 to alter thyroid function, therefore all COVID-19 patients should be monitored regarding endocrinological changes and TSH, fT3, fT4 should be assessed.

OCLC Number/Unique Identifier: 9138596883

Objective: This study discusses strategies to overcome hypertension patient compliance to manage self-care. The purpose of the study is to provide a summary of the importance of attention to managing hypertension. Method: a review of literature relevant to hypertension, policies, and management, both pharmacological and non-pharmacological, through cross-programs or sectors. Result: This study found that the ministry of health had compiled various policies to reduce the prevalence of hypertension, including technical guidelines for its implementation, but the strategy has not yet fully reached the minimum service standard, which is because it has not fully involved the relevant cross sectors. Conclusion: Improve the coordination system by “Joint Decree” between the Ministry of Health and the Ministry of Villages, PDT and Transmigration, the Ministry of Social Affairs, Indonesian National Army, police, and NGOs to carry out activities simultaneously to the community.

Meclizine prescriptions in the Emergency Department and return visits in the elderly population

Published on: 11th June, 2021

OCLC Number/Unique Identifier: 9124652483

Background: Meclizine is a commonly prescribed medication for patients discharged from the Emergency Department (ED) with a diagnosis of peripheral vertigo, however it is on the Beers list of medications to avoid in elderly patients. Objectives: This study aims to determine the correlation between use of meclizine and return visits to the ED within 1 week in patients > 65 years old. Methods: This is a retrospective observational study conducted at 2 urban tertiary care EDs over 5 years. Inclusion criteria included patients > 65 years who were given meclizine in the ED or discharged with a prescription. Charts were reviewed for diagnosis, prescriptions and return visits within 7 days. Results: There were a total of 1608 patients over 65 years of age who met inclusion criteria, 669 patients identified as receiving meclizine in the ED and 962 who received no meclizine (ED or ED plus home prescription). Of the meclizine patients, 548 (84.8%) were given home prescriptions, of which there were 36 (6.6%) return visits within 7 days. Patients who were given meclizine while in the ED without home prescriptions (121) had 16 return visits (13.2%). Among the non-meclizine group, 102 patients (10.6%) had a return visit within 7 days. Conclusion: There was no increase in return visits in elderly patients discharged from the ED with a prescription for meclizine after a diagnosis of benign dizziness. Meclizine prescriptions at discharge were associated with fewer return visits to the ED within 1 week. Ongoing dizziness was the most common reason for return visits; there were no documented chief complaints of weakness, syncope/falls, or hypotension.

Identification and resolution of drug therapy problems among hypertensive patients receiving care in a Nigerian Hospital - A pilot study

Published on: 1st October, 2020

OCLC Number/Unique Identifier: 8677986406

Background: An event involving drug therapy that actually or potentially interfers with the desired health outcomes is known as drug therapy problem. Objective: The study aimed to identify and resolve potential drug related problems encountered among adult hypertensive patients receiving care in a Nigerian Tertiary Hospital. Methods: This was a prospective cross sectional study. The data were collected from the patients’ medical records using the Pharmaceutical Care Network Europe (PCNE) Classification tool Version 6.2 (PCNE, 2010). For each of the 171 medical records, the DTPs experienced within the study period were identified. Data were analyzed using the IBM Statistical Product and Service Solutions (SPSS) for Windows, Version 21.0 (IBM Corp, Version 21.0, and Armonk, NY, USA). Results: Majority of the patients were above 65years of age 64(37.4%), while about half of the patients were females. A total of 644 drug therapy problems were identified. The major cause of DTP was prescribing error 189(29.3). Other causes of drug therapy problem identified in this study were inappropriate drug selection 122(18.9), no indication for drugs 52(8.1), inappropriate drug combination 87(13.6), new indication presented 61(9.5), dose too high 62(9.6), dose too low 44(6.8), wrong drug taken/administered 27(4.2). Majority of the interventions made were accepted 586(91.0%) while only 3(0.5%) of the interventions made were not accepted. Conclusion: This study demonstrates that a pharmacist, with adequate training and support can play a vital role in identifying and resolving drug therapy problems. Also, there is a need for an educational intervention among prescribing physicians to update them regularly on hypertension guidelines.
