Amniotic membrane extract or deferoxamine could be used interchangeably in angiogenesis within wound healing due to their high safety and availability.
In this study, using latent class analysis (LCA), we investigated whether there are any homogeneous subclasses of individuals exhibiting different profiles of metabolic syndrome (MetS) components. The current study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS), a population-based cohort including 6448 subjects, aged 20–50 years. We carried out a LCA on MetS components and assessed the association of some demographic and behavioral variables with membership of latent subclasses using multinomial logistic regression. Four latent classes were identified:(1) Low riskclass, with the lowest probabilities for all MetS components (its prevalence rate in men: 29%, women: 64.7%), (2) MetS with diabetes medication (men: 1%, women: 2.3%), (3) Mets without diabetes medication (men: 32%, women: 13.4%), (4) dyslipidemia (men: 38%, women: 19.6%). In men the forth subclass was more significantly associated with being smoker (odds ratio: 4.49; 95% CI: 1.89–9.97). Our study showed that subjects with MetS could be classified in sub-classes with different origins for their metabolic disorders including drug treated diabetes, those with central obesity and dyslipidemia associated with smoking.
Oral lichen planus is a premalignant chronic inflammatory mucosal disorder with unknown etiology. It is a multifactorial disease and in addition to genetic background, infections, stress, drug reactions are suggested as risk factors. Helicobacter pylori which is involved in development of many gastrointestinal lesions may also be implicated in oral lichen planus induction. This is of clear importance for cancer prevention and the present study was performed to determine any association between H. pylori infection and oral lichen planus in southwestern Iran. Anti H. pylori IgG levels were determined in 41 patients and 82 sex-age matched controls. The results showed no association between H. pylori infection and oral lichen planus (51% in patients vs. 66% in control). or any of its clinical presentations.
Alipour A., Veisi H., Darijani F., Mirbagheri B., Behbahani A.G., 2012. Study and determination of energy consumption to produce conventional rice of the Guilan province. Res. Agr. Eng., 58: 99-106.The aim of this study was to determine the energy efficiency indices in the agro-ecosystems of the Guilan province in 2010. One hundred and twenty-seven farmers were interviewed using a particularly designed questionnaire. The inputs in the calculation of energy use in agro-ecosystems embraced labour, machinery, electricity, diesel oil, fertilizers, seeds, while rice and straw yield were included in the output. The results depicted that total input and output energy into these agro-ecosystems were about 47,604 and 90,680.04 MJ/ha, respectively. The highest energy input was related to water (38.84%), electricity (27.87%) and nitrogen fertilizer (17.5%). Energy efficiency and energy productivity in these agro-ecosystems was 2.19 and 0.064 kg/MJ, respectively, and water productivity was 0.11 kg/m 3 . The results also showed that due to application of flood irrigation in these agro-ecosystems and also water elicited from subterranean sources by electrical pump, the inputs had the largest portion among the energy inputs to agro-ecosystems that this matter increased energy use in the unit area and also reduced energy efficiency and productivity.
Objective: Job burnout can cause physical and psychological damage and reduce job efficiency, especially in difficult jobs such as health care fields. This study aimed to assess the association between the level of job burnout and some contributing factors among health care providers in Iran.
Method: This study was performed on the data derived from 1807 participants from the first phase of the employees’ health cohort in 2017-2018. The data were collected using as a self-administrated tool utilizing Maslach Burnout Inventory. The questionnaire scores ranged from never to everyday, with 3 levels of burnout as well as burnout itself; then, the scores were categorized as low, moderate, or high. Ordinal logistic regression model was used to adjust ordinal dependent variables.
Results: The mean score of the total burnout was 16.5±7.77 and was associated with work experience and age group (p < 0.001). The components of burnout consisted of emotional exhaustion (8.9± 9.0), depersonalization (23± 2.9), and personal accomplishment (34± 8.6). Emotional exhaustion was related to sex (less among males, OR=0.48) and type of job (less among officials compared to health care staff, OR=0.488). Composite burnout was more common among younger staff (OR= 3.85). Depersonalization was associated with duty shift workers (OR=2.42).
Conclusion: Job burnout is a major concern, and lack of personal accomplishment, as a component of burnout, was highly prevalent among Iranian health care employees. Being a single woman, health care provider, and having more than 20 years of work experience with a duty shift were contributing factors for burnout experience. Monitoring symptoms of burnout and its associated factors in the workplace and proposing an alternative organizational and behavioral system and sharing it with relevant authorities may help prevent or reduce job burnout and its deleterious effects.
