Effectiveness of Wet Cupping Therapy for Migraine in Mojokerto, East Java

Background: Cupping therapy is an ancient form of alternative medicine in which a therapist puts special cups on the patient skin for a few minutes to create suction. It is used for various purposes, including to help with pain, inflammation, blood flow, relaxation and well-being, and as a type of deep-tissue massage. Wet cupping creates a mild suction by leaving a cup in place for about 3 minutes. The therapist then removes the cup and uses a small scalpel to make light, tiny cuts on your skin. Next, the therapist does a second suction to draw out a small quantity of blood. This study aimed to determine effectiveness of wet cupping therapy for migraine. Subjects and Method: This was a quasi experiment before and after with no control design conducted in Mojokerto, East Java. A sample of 57 patients with migraine was selected for this study. The dependent variable was migraine pain level. The independent variable was wet cupping therapy. Pain level was measured by visual analog scale (VAS). Pain level before and after cupping therapy were compaired by paired t test. Results: Pain level of migraine after wet cupping therapy (mean= 2.40; SD= 1.10) was lower than before (mean= 9.21; SD= 1.57), and it was statistically significant (p= 0.024). Conclusion: Wet cupping therapy is effective to relieve pain of migraine. Keywords: wet cupping therapy, pain, migraine

A Technical Analysis Investigating Energy Sustainability Utilizing Reliable Renewable Energy Sources to Reduce CO2 Emissions in a High Potential Area

©2020 Elsevier Ltd. All rights reserved. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1016/j.renene.2020.09.042Reduction of carbon dioxide (CO 2) emissions will have a positive impact on the environment by preventing adverse effects of global warming. To achieve an eco-environment, the primary source of energy needs to shift from fossil fuels to clean renewable energy. Thus, increased utilization of renewable energy overtime reduces air pollution and contributes to securing sustainable energy supply to satisfy future energy needs. The main purpose of this study is to investigate several sustainable hybrid renewable systems for electricity production in Iran. In this regard, critical indicators that have the strongest impact on the environment and energy sustainability are presented in this study. After a comprehensive review of environmental issues, data was collected from the meteorological organization and a techno-economic assessment was performed using HOMER software. It was concluded that the hybrid configuration composed of photovoltaic (PV), wind turbine, diesel generator and battery produced the best outcome with an energy cost of 0.151$/kWh and 15.6% return on investment. In addition, the results showed that with a higher renewable fraction exceeding 72%, this hybrid system can reduce more than 2000 Kg of CO 2 emission per household annually. Although excess electricity generation is a challenge in stand-alone systems, by using the fuel cell, an electrolyzer, and a hydrogen tank unit, the amount of energy loss was reduced to less than one-sixth. These results show that selecting useful indicators such as appropriate implementation of policies of new enabling technologies and investments on renewable energy resources, has three potential benefits namely: CO 2 reduction, greater sustainable electricity generation and provides an economic justication for stakeholders to invest in the renewable energy sector.Peer reviewe

Characteristics and outcomes of an international cohort of 600 000 hospitalized patients with COVID-19

Background: We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, one of the world's largest international, standardized data sets concerning hospitalized patients. Methods: The data set analysed includes COVID-19 patients hospitalized between January 2020 and January 2022 in 52 countries. We investigated how symptoms on admission, co-morbidities, risk factors and treatments varied by age, sex and other characteristics. We used Cox regression models to investigate associations between demographics, symptoms, co-morbidities and other factors with risk of death, admission to an intensive care unit (ICU) and invasive mechanical ventilation (IMV). Results: Data were available for 689 572 patients with laboratory-confirmed (91.1%) or clinically diagnosed (8.9%) SARS-CoV-2 infection from 52 countries. Age [adjusted hazard ratio per 10 years 1.49 (95% CI 1.48, 1.49)] and male sex [1.23 (1.21, 1.24)] were associated with a higher risk of death. Rates of admission to an ICU and use of IMV increased with age up to age 60&nbsp;years then dropped. Symptoms, co-morbidities and treatments varied by age and had varied associations with clinical outcomes. The case-fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients and was on average 21.5%. Conclusions: Age was the strongest determinant of risk of death, with a ∼30-fold difference between the oldest and youngest groups; each of the co-morbidities included was associated with up to an almost 2-fold increase in risk. Smoking and obesity were also associated with a higher risk of death.&nbsp;The size of our international database and the standardized data collection method make this study a comprehensive international description of COVID-19 clinical features. Our findings may inform strategies that involve prioritization of patients hospitalized with COVID-19 who have a higher risk of death
