Background Suicide is a critical psychological issue worldwide with an increasing trend. This study investigated suicide comprehensively. Methods In this cross-sectional study, we reviewed data of 28 552 suicide attempts during 2011–16, in Southern Iran. To calculate age-standardized incidence rates, population statistics were derived from the Statistical Center of Iran and the National Organization for Civil Registration. We used the standard population of World Health Organization 2012 to adjust the suicide attempts and deaths rates by age. Results The mean age of participants was 26.8 ± 10.6 years with the highest suicide attempts rates in the age groups of 15–24 and 25–34 years (48% and 32.5%, respectively); 58.7% were women and 52.9% were single. Case-fatality rate (CFR) was 6.27%. Annual age-standardized incidence rates of suicide attempts during the 6-year period has increased (P < 0.001), and that of deaths were not incremental (P > 0.05). Logistic regression model showed male sex, rural area, older age, psychological and somatic disorders, and family history of suicide as significant factors. Conclusions In this comprehensive study, although the age-standardized mortality rate of suicide in southern Iran was lower than in other countries, the increasing trend of suicide attempts during the study period served as an alarming sign in this province.

Acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. The analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. The changes in long-term average spectrum (LTAS) spectral tilt and harmony to noise ratio (HNR) were analyzed to assess the voice quality before and after functional rhinoplasty in patients with internal nasal valve collapse. Before and 3 months after functional rhinoplasty, 12 participants were evaluated and HNR and LTAS spectral tilt in /a/ and /i/ vowels were estimated. It was seen that an increase in HNR and a decrease in LTAS spectral tilt existed after surgery. Mean LTAS spectral tilt in vowel /a/ decreased from 2.37 ± 1.04 to 2.28 ± 1.17 (P = 0.388), and it was decreased from 4.16 ± 1.65 to 2.73 ± 0.69 in vowel /i/ (P = 0.008). Mean HNR in the vowel /a/ increased from 20.71 ± 3.93 to 25.06 ± 2.67 (P = 0.002), and it was increased from 21.28 ± 4.11 to 25.26 ± 3.94 in vowel /i/ (P = 0.002). Modification of the vocal tract caused the vocal cords to close sufficiently, and this showed that although rhinoplasty did not affect the larynx directly, it changes the structure of the vocal tract and consequently the resonance of voice production. The aim of this study was to investigate the changes in voice parameters after functional rhinoplasty in patients with internal nasal valve collapse by computerized analysis of acoustic characteristics.

Introduction: The main objective of this study was to determine the mental health status of population aged 15 and over in the province of Fars in 2015. Methods: The statistical population of this cross-sectional field survey consisted of residents of urban and rural areas of Fars in Iran. Through systematic random cluster sampling, 1200 individuals were selected from the residents of urban and rural areas of Shiraz, Jahrom and Kazeroun. The 28-item version of the General Health Questionnaire was applied as the screening tool. The data were analyzed using SPSS, version 18.0 for windows. Results: This study showed that using the traditional scoring method, 22.5% of the subjects (26.9% of females and 18% of males) were suspected of having mental disorders. The prevalence of suspected psychiatric disorders in urban areas (24.3%) was more than the prevalence of these disorders in rural areas (18.6%). The prevalence of suspected anxiety and the somatization of symptoms was higher than the prevalence of social dysfunction and depression, and the prevalence of these components was higher in women than men. The findings of this study also showed that the prevalence of suspected mental disorders increased significantly with age. The prevalence of suspected cases of these disorders was higher among women, the age group of 65 and older, people living in urban areas, divorced and widowed, illiterate, and retired compared to other groups. Conclusion: The results of this study show that more than a fourth of the sample were suspected of mental disorders, and the prevalence of these disorders has decreased from 22.9% in 1999 to 22.5% in 2015. Therefore, it seems necessary for the provincial public health authorities to take the needed steps for providing requirements encompassing prevention and promotion of mental health in this area.
