Characteristics of flavored and non-flavored waterpipe tobacco users: a real-world setting study.

We aimed to compare sociodemographic characteristics, smoking patterns, beliefs and perceptions, nicotine dependence, and psychological indicators between flavored waterpipe (WP) tobacco (FWT) and non-flavored WP tobacco (non-FWT) smokers in Iran. A cross-sectional study was conducted in 94 WP-serving venues surrounding Tehran and Ardabil metropolitans in Iran. Convenience sampling was applied to select 900 current WP smokers [508 (56%) FWT-only and 392 (44%) non-FWT-only smokers] aged 18 years and older.

Insecticide Susceptibility Status of Wild Population of and Collected from Visceral Leishmaniasis Endemic Foci in Northwestern Iran.

Background: and sand flies are the vectors of visceral leishmaniasis in Iran. The aim of this study was to evaluate the susceptibility of and , collected from an endemic focus of visceral leishmaniasis (VL) in the northwest of Iran, to different selected insecticides.

Methods: Sand flies were collected from the villages of Meshkinshahr and Germi Counties using light traps and aspirators from May to October 2019.

Exposure to BTEX concentration and the related health risk assessment in printing and copying centers.

This study was derived to investigation of BTEX (benzene, toluene, ethylbenzene, xylenes) concentrations in printing and copying centers (PCCs) in Ardabil city of Iran. Fifty-three PCCs were randomly selected from all the 136 number of PCCs and BTEX was sampled form their indoor air. The results showed that the concentration of BTEX in the indoor air PCCs is lower than the OELs (occupational exposure limit) in all cases.

Pattern of Crimean-Congo hemorrhagic fever related high risk behaviors among Iranian butchers and its relation to perceived self-efficacy.

Background: Crimean-Congo hemorrhagic fever (CCHF) is highly fatal to humans and an acute viral disease. The CCHF disease has been reported in occupations such as butchers, slaughterhouse butchers and workers. The aim of this study was to investigate the pattern of CCHF related high risk behaviors among butchers and determine the effects of perceived self-efficacy of the participants on their membership in latent classes.

Assessment of types of bacterial bio-aerosols and concentrations in the indoor air of gyms.

The presence of airborne microorganisms in indoor air (home and work) is a serious public health concern. Bio-aerosols have a significant role in indoor air pollution as they can be pathogenic or cause an allergic reaction following inhalation, ingestion or skin absorption. This study aimed to assess bacterial bio-aerosols in the indoor air concentration of gyms, and its relationship with gym area per person, temperature, and relative humidity.

The Relationship between Quality of Life and Physical Activity, Worry, Depression, and Insomnia in Pregnant Women.

Physical activity (PA), insomnia, depression, and worry were the key factors affecting pregnant women's quality of life (QoL). The present study aimed to determine quality of life and its relationship with physical activity, insomnia, depression, and worry in pregnant women. This was an observational cross sectional study, conducted among 256 healthy pregnant women using 5 questionnaires: WHOQOL-brief (WHO Quality of Life Questionnaire, brief version, ISI (Insomnia Severity Index), PSWQ (Penn State Worry Questionnaire), ZSRDS (Zung Self-Rating depression Scale), and Pregnancy Physical Activity Questionnaire (PPAQ).

Forecasting head lice (: ) infestation incidence hotspots based on spatial correlation analysis in Northwest Iran.

Background And Aim: has been prevalent throughout the world, especially in developing countries among elementary students and societies with a weak socio-economic status.
