Clinical outcome of tracheal extubatedcardiac surgery patients who did not meet protocol driven laboratory criteria for extubation
Background: We retrospectively compared the clinical outcome of post-cardiac surgery tracheal extubation between patients extubated with a lower than normal pH and patients extubated according to our routine institutional protocol. Our main goal was to clarify that strict adherence to the current criteria is dispensable.
Methods: In this retrospective cohort study, we recruited 256 patients who met our study criteria and divided them into the exposed group (n= 95) and the control group (n= 161). The inclusion criteria consisted of coronary artery bypass grafting alone and age> 18 years. The exclusion criteria comprised the use of corticosteroids in the preceding 2 weeks, Serum creatinine (SCr)> 2 mg/dL, uncontrolled diabetes, liver dysfunction, Glasgow coma scale <13, and acetazolamide and sodium bicarbonate use. The arterial blood gas (ABG) characteristics before and 6 hours after extubation, extubation failure rate, length of stay in the in ICU, length of stay in the hospital and mortality were compared between the two groups.
Results: In the control group, the males outnumbered the females and the ejection fraction was higher relative to that in the exposure group (P= 0.01 and P= 0.02, respectively). There were more patients with chronic obstructive pulmonary disease in the exposure group (P< 0.005) and also the euroSCORE was higher (P< 0.002). There were no significant differences between the groups regarding the ABG values at the time of ICU admission. Significantly higher levels of FiO2 and PaCO2 (P< 0.001 for both) as well as lower HCO3 and pH (P< 0.001 for both) were observed in the exposure group immediately before extubation. Following extubation, there was a significant increase in pH and a significant reduction in FiO2 need in the exposure group (P< 0.001 for both). The extubation failure rate, length of stay in the in ICU, length of stay in the hospital, and mortality rate were not different between the 2 groups.
Conclusion: The patients with a lower than normal pH, tracheal extubated at the discretion of the ICU anesthesiologist did not have a clinical outcome worse than that of the patients extubated in accordance with our routine institutional protocol
Synthesis and Pharmacological Evaluation of New 2-Substituted-5-{2-[(2-halobenzyl)thio)phenyl}-1,3,4-oxadiazoles as Anticonvulsant Agents
A new series of 2-substituted-5-{2-[(2-halobenzyl)thio)phenyl}-1,3,4-oxadiazoles was designed, synthesized and investigated for anticonvulsant activities. The designed compounds contain the main essential pharmacophore for binding to the benzodiazepine receptors. Conformational analysis and superimposition of energy minima conformers of designed molecules on estazolam, a known benzodiazepine receptor agonist, revealed that the main characteristics of the proposed benzodiazepine pharmacophore were well matched. Electroshock and pentylenetetrazole-induced lethal convulsion tests showed that some of the synthesized compounds had significant anticonvulsant activity. The structure-activity relationship study of these compounds indicated that the introduction of an amino group at position 2 of 1,3,4-oxadiazole ring and a fluoro substituent at the ortho position of the benzylthio moiety had the best anticonvulsant activity. Anticonvulsant effects of active compounds were antagonized by flumazenil, a benzodiazepine antagonist, which establish the involvement of benzodiazepine receptors in these effects

The association between dietary intake and cervical cancer in women at risk of cervical cancer; a nested case-control study
Background: The risk of cervical cancer was reported to be influenced by dietary
components. This study aimed to illustrate the association between cervical cancer with the
intake of food groups in women with a history of cervical neoplasia.
Methods: This nested case-control study was conducted in 558 people with a history of
cervical intraepithelial neoplasia (CIN), including 279 women with cervical cancers and 279
controls with low-grade squamous intraepithelial lesions (LSIL). A validated food frequency
questionnaire (FFQ) was used to assess the intake of food groups.
Results: The intake of fruits and vegetables in the case group was significantly lower than
the control group (P=0.001). Low intake of dairy products, vegetables, and fruits was
associated with cervical cancer risk (OR=4.67; 95% CI 1.2-9.49, P=0.001; OR=9.75, 95%
CI 1.36-19. 51, P=0.001; and OR=4.82, 95% CI 1.09-7.25, P=0.001, respectively). After
adjusting for age, family history, age at first menstruation, number of children, history of
vaginal infection, and age at first sexual intercourse, the results were still significant.
Additional adjustments to BMI did not change the results.
Conclusion: The results indicate that the risk of cervical cancer can be affected by the intake
of certain food groups. Further longitudinal studies are needed to confirm these findings and
determine the underlying mechanism of the influence of dietary components on cervical
cancer risk

Depression and anxiety both associate with serum level of hs-CRP: a gender- stratified analysis in a population-based study
Background: Depression and anxiety are two important mood disorders that are frequently associated with chronic diseases such as cardiovascular diseases (CVDs). Hyper-inflammation is related to both CVDs and psychological conditions such as depression and anxiety. Therefore, inflammation may partially explain the relationship between depression and cardiovascular disease.
Objective: The objective of this study was to perform a gender-stratified examination of the association between symptoms of depression/anxiety disorders and serum hs-CRP and inflammation linked conditions in a large Iranian population.
Methods: Symptoms of depression and anxiety disorders and serum hs-CRP levels were measured in 9759 participants (40% males and 60% females) aged 35–65 years, enrolled in a population-based cohort (MASHAD) study in north-eastern Iran. Symptoms of depression and anxiety were evaluated with Beck Depression and Anxiety Inventories. According to the scores of depression and anxiety, individuals were categorized into four groups of no or minimal, low, moderate and severe categories.
Results: The median serum hs-CRP concentration increased with increasing severity of depression and anxiety disorders. Male participants with severe depression had significantly higher levels of hs-CRP (p < 0.001); however, this relationship was less marked among women (p = 0.04). Subjects with severe anxiety also had significantly higher levels of hs-CRP (p < 0.001). Moreover, women with severe depression and anxiety had higher BMI. There was also a positive association between current smoking habit and depression/anxiety disorders.
Conclusion: Depression and anxiety disorders are associated with elevated levels of hs-CRP, particularly among men. Also, there is a significant positive association between depression/anxiety disorders and inflammation linked conditions such as smoking and obesity; however, in the case of obesity this association is only present in women
