The Effect of Occupational Stress and Concerns about the COVID-19 Pandemic on Secondary Traumatic Stress Syndrome among Iranian Frontline Nurses: A Mediating Model

Objective: With the increasing effects of stress caused by the COVID-19 pandemic and occupational stress on the mental health of frontline nurses, it is imperative to further investigate how these stresses affect nurses' mental health and secondary traumatic stress syndrome. This research aimed to investigate the relationship of nurses' occupational stress and concerns about COVID-19 with secondary traumatic stress syndrome, and also to investigate the mediating effect that concerns about the COVID-19 pandemic have on the relationship between nurses' occupational stress and secondary traumatic stress syndrome. Method : A cross-sectional design was adopted. The population of the study was defined as all front-line nurses in Shiraz hospitals, from which 225 nurses of two corona care hospitals were selected using convenience sampling. The degree of secondary traumatic stress, concerns about the COVID-19, and nurses' occupational stress were assessed using Bride's Secondary Traumatic Stress Scale (STSS), an adopted version of Level of Concerns about the COVID-19 questionnaire, and the Nurses' Occupational Stressor Scale (NOSS) among Hospital-based Healthcare Workers. Structural equation modeling (SEM) was used to examine the relationships among variables. Results: Results showed that nurses' occupational stresses presented a direct effect on nurses' level of concern about the COVID-19 pandemic (β = 0.85, P < 0.001), and concern about the COVID-19 pandemic was directly related to front-line nurse's secondary traumatic stress syndrome (β = 0.83, P < 0.001). In addition, nurses' level of concern about the COVID-19 pandemic fully mediated the effects of nurses' occupational stresses on their secondary traumatic stress (β = 0.70, P < 0.001). This indirect effect has explained 68% of the variance in nurses' secondary traumatic stress. Conclusion: These results emphasized the indirect effect of nurses' occupational stresses on secondary traumatic stress syndrome via mediating the level of concern about COVID-19. Therefore, to reduce the secondary traumatic stress of nurses who have dealt directly with COVID-19 patients, it seems necessary to pay serious attention to the sources of their occupational stress, which probably existed even before this pandemic and increased their concerns in pandemic conditions.

The serum vitamin D levels in children with urinary tract infection: a case-control study

Urinary tract infection (UTI) is one of the most common infections in infants and children. The aim of this study is to evaluate the association between vitamin D levels and urinary tract infections in children. This case-control study was performed on 80 children aged 1–12 years with urinary tract infection referred to the pediatric clinic of Mousavi Hospital in Zanjan, Iran. For each patient in the case group, an individual of the same age and sex was selected in the control group. Vitamin D was measured by the ELISA method. Statistical analysis was performed by SPSS V22 software. In this study, 80 children were divided into two groups of 40 cases (UTI) and control. Serum levels of vitamin D in the case group were significantly lower than in the control group [OR (95%CI) = 3.316 (1.286–8.550),( p = 0.013)]. In females, serum levels of vitamin D in cases were significantly lower than for controls [OR (95%CI) = (5.417 (1.685–17.417), P-value = 0.005)]. No significant relationship was found between serum levels of vitamin D in cases and controls regarding male gender, age and weight. Conclusions: This study showed that vitamin D deficiency has a significant relationship with the prevalence of UTI in children. Vitamin D deficiency and female gender are more frequent risk factors for UTI.

Challenges in a child with asthma and COVID-19

Today clinicians may diagnose hundreds of people with coronavirus disease 2019 (COVID-19). We report the case of a child with asthma who sought care for COVID-19 symptoms whose condition did not improve despite appropriate treatment for asthma, pneumonia and COVID-19. Further examination revealed a surprising underlying disease. It is important to consider that in pandemics such as COVID-19, because all attention is paid to the disease, underlying hidden causes may be neglected.

Reliability and validity of the Self-report Family Content Scale

The aim of the study was to assess the reliability and validity of Self-report Family Content Scale for measurement of a contextual and psychoeducational model for family studies. The sample included 450 college students at Shiraz University (241 women, 209 men; M age=27.5 yr., SD=3.8). Principal-components factor analysis indicated a 7-factor solution. The mean correlations among factors and between factors and the total score of the scale were .18 and .42, respectively. Coefficients alpha indicated good reliability and internal consistency for the scale.
