Indoor Air Pollution (IAP) from smoky cooking fires causes deaths over 22,800 per year being the fourth leading cause of death in Nepal. The study aims to compare the pollution level particularly Carbon Monoxide (CO) and Particulate Matter (PM 2.5 ) in different firewood species. Two households one with ICS and TCS is selected purposively to monitor the concentration of pollutants in Ward no. 3 of Gatlang, Rasuwa, Nepal. IAP Meter based on Laser Sensor principle is used to monitor real time concentration of PM 2.5 and CO. 24 hours mean concentration of PM 2.5 and 8 hours mean average concentrations of CO are found to be above the WHO and National Indoor Air Quality Guidelines i.e. For ICS using household the concentration is found to be 155.26 µg/m 3 and 9 ppm respectively and household using TCS is found to be 385.12 µg/m 3 and 12.2 ppm). Both pollutants’ concentration is found less in Abies Spectabilis than other species. Positive correlation is found in both households along with moisture content, amount of firewood used, etc. This result suggests the use of Abies Spectabilis as it emits less emission as compared to other species as it has less moisture content that reduces the concentration of air pollution.

Background:Although various antihypertensive medications are available, some hypertensive patients have uncontrolled blood pressures, especially in the clinic. The aim of the present study was to compare the efficacies of various antihypertensive therapies in our hypertension (HTN) clinic (monotherapy vs. combination therapy, fixed-dose combination (FDC) versus free equivalent combination (FEC), and diuretics versus non-diuretics. Material/Methods:In this retrospective study, patients at the HTN clinic of the Third Xiangya Hospital with primary hypertension were enrolled from June 2016 to February 2017. Data on participants' basic characteristics, blood pressure data, and treatment modalities were collected. The proportions of participants attaining target blood pressure after treatment with antihypertensive modalities were calculated and compared. Results:Among 1900 participants, combination therapy had a better control efficacy than monotherapy (P<0.0005).When HTN was treated by 2 kinds of drugs, FEC was used much more frequently than FDC (P<0.0005). In grade 3 HTN, FDC had a higher control rate (P=0.002). If more than 2 kinds of drugs were used, FDC+OTHER had a slightly higher control rate in grade 2 and 3 (42.1% vs. 38.5%, P=0.724; 36.2% vs. 31.0%, P=0.526, respectively). Therapies with diuretics had better control rates than those without diuretics (43.1% vs. 36.9%, P=0.025). Conclusions:In our clinic, FEC was prescribed more often than FDC. When blood pressure is significantly elevated, especially at levels 2 or 3, FDC seems to have a better control rate than FEC. Therapies with diuretics controlled HTN more efficiently.
