Shared decision making in Iran: Current and future trends.
Authors: Rahimi SA, Alizadeh M, Légaré F Abstract This paper describes the current situation of shared decision making (SDM) in the Iranian healthcare system, discusses barriers to implementation and gives future directions. What about policy regarding SDM? Although the Ministry of Health and Medical Education has enacted some legislation on informed consent and patients' rights, there is no policy specifically regarding SDM in Iran. What about decision support tools for patients? Although some Iranian researchers and clinicians have highlighted patients' desire to be informed and involved in decision...

Application of Cox and Parametric Survival Models to Assessment Social Determinants of Health Affecting the Three-Year Survival of Breast Cancer Patients
This study aimed to determine those influencing breast cancer survival time with parametric and semi-parametric regression models. Materials and Methods: This cross-sectional study was conducted on male and female patients diagnosed with breast cancer presenting to the Cancer Research Center of Shohada-E-Tajrish Hospital from 2006 to 2010. Cox proportional hazard and parametric models including the Weibull, lognormal and log-logistic were applied to determine the social determinants of survival time of breast cancer patients. The Akaike information criterion (AIC) was used to assess the best fit. Statistical analysis was p...

Comparison of Cox Regression and Parametric Models: Application for Assessment of Survival of Pediatric Cases of Acute Leukemia in Southern Iran
Conclusion: Parametric regression models demonstrate better performance as compared to the Cox model for identifying risk factors for prognosis with acute leukemia data. Just because the assumption of PH (Proportional Hazards) is held for the Cox regression model, we should not ignore parameter models.

BRD4 facilitates DNA damage response and represses CBX5/Heterochromatin protein 1 (HP1).
Authors: Pongas G, Kim MK, Min DJ, House CD, Jordan E, Caplen N, Chakka S, Ohiri J, Kruhlak MJ, Annunziata CM Abstract Ovarian cancer (OC) is a heterogeneous disease characterized by defective DNA repair. Very few targets are universally expressed in the high grade serous (HGS) subtype. We previously identified that CHK1 was overexpressed in most of HGSOC. Here, we sought to understand the DNA damage response (DDR) to CHK1 inhibition and increase the anti-tumor activity of this pathway. We found BRD4 suppression either by siRNA or BRD4 inhibitor JQ1 enhanced the cytotoxicity of CHK1 inhibition. Interestingly, BRD4 ...

CONCLUSIONS: Psychiatric diagnoses are very frequent in PWS and strongly influence QOL. Furthermore, characterizing the profile of psychiatric comorbidity in PWS is crucial for planning effective interventions. Precise behavioral phenotyping in PWS in combination with a well-defined genetic etiology may aid biological research linking biological correlates to behavior.

Iranian Nurses' Challenges in Caring for Older Adults: A Content Analysis Study
The current study describes Iranian nurses' challenges in caring for older adults. Participants included 22 nurses who were selected by purposeful method and underwent semi-structured, face-to-face interviews. The interviews were reviewed, and three categories and seven subcategories were noted. The categoryolder adults –nurse interaction challenges included: specific characteristics of older adults and inappropriate interaction between nurses and older adults. The categorystructural problems included: shortage of nurses, inappropriateness of ward environment, and service problems. The categoryeducational gap include...

Vacuolar digestion of entire damaged chloroplasts in Arabidopsis thaliana is accomplished by chlorophagy.
Abstract In yeast and mammals, selective vacuolar delivery and degradation of whole mitochondria, or mitophagy, represents an important quality control system and is achieved by a cargo recognition mechanism enabling selective elimination of dysfunctional mitochondria. As photosynthetic organelles that need light for energy production, plant chloroplasts accumulate sunlight-induced damage. Plants have evolved multiple mechanisms to avoid, relieve, or repair chloroplast photodamage. Our recent study showed that vacuolar degradation of entire chloroplasts, termed chlorophagy, is induced to degrade chloroplasts that ...

Rurality or distance to care and the risk of homelessness among Afghanistan and Iraq veterans
We examined differences in the rate of homelessness within a year of a Veteran ’s first encounter with the VA following last military separation based on rurality and distance to the nearest VA facility using multivariable log-binomial regressions. Findings In our cohort of 708,318 Veterans, 84.3% were determined to have a forwarding address in urban areas, 60.4% and 88.7 % lived within 40 miles of the nearest VA medical center (VAMC), respectively. Veterans living in a rural area (RR=0.763; 95% CI=0.718-0.810) and those living between 20-40 miles (RR=0.893; 95% CI=0.846-0.943) and 40+ miles away from the nearest VAM...

Does the emergency surgery score accurately predict outcomes in emergent laparotomies?
The emergency surgery score is a mortality-risk calculator for emergency general operation patients. We sought to examine whether the emergency surgery score predicts 30-day morbidity and mortality in a high-risk group of patients undergoing emergent laparotomy. (Source: Surgery)
