Poor pain control in burn patients as a great public health problem disrupts the healing and rehabilitation process and results in several adverse outcomes. The aim of this study was to investigate the efficacy and safety of intravenous lidocaine in reducing the pain of burn injuries.
Materials and MethodsFrom August 2014 to March 2015, 66 eligible burn patients participated in the study and were randomly divided into two groups of lidocaine (L) and placebo (P). In group L, lidocaine 2% was injected at a bolus dose of 1.5 mg/kg followed by infusion at the dosage of 1.5 mg/kg/h, and in group P, saline was administrated. Pain severity was measured during 24 hours at baseline and 1, 2, 4, 8, 12, 16, 20, 24 hours after intervention based on Numerical Rating Scale (NRS-11). Morphine consumption, Ramsay score, and side effects were also documented.
ResultsFinally the data from 60 patients were analyzed. Comparing baseline with 24 hours after intervention, NRS-11 scores decreased from 7.12±1.42 to 3.33±0.76 (P<0.001) in group P and from 6.45±1.02 to 2.50±0.72 (P<0.001) in group L. Moreover, the mean of NRS scores during 24 hours in the lidocaine group was significantly lower compared to the placebo group, 3.93±0.72 vs 4.73 ±1.14, (P=0.03). The mean amounts of morphine consumption in group L were significantly lower compared to group P, 14.41 ± 4.86 vs 21.07±6.86, (P=0.001). The mean of Ramsay score in group L was significantly lower compared to group P, 1.38±0.59 vs 1.45±0.6, (P=0.014).
ConclusionsThis study revealed that intravenous lidocaine was an effective and safe drug for pain reduction in burn patients.

Traditional guidelines for preoperative fasting (POF) time lead to several complications in surgery patients. However, not enough attention has been paid to the issue. This aimed of this study was to investigate the management of fasting times in Guilan academic hospitals.
Materials and MethodsIn this descriptive cross-sectional study, individuals from five academic referral centers enrolled the survey and questionnaires including demographic characteristics, fasting hours for liquids and solids, POF recommenders, and patient’s knowledge regarding the definition of clear liquids were completed.
ResultsA total of 390 individuals candidate for elective surgeries enrolled in the study, the mean age of our cases were 46.61 years. The average POF time for solids and liquids was 11.43 and 9.70 hours, respectively. 95.38% of the participants did not know a correct definition of clear liquids, which was not related to their level of education (P=0.314). A positive association was observed between age and POF times for liquids and American Society of Anesthesiologists Classification for both solids (P=0.010) and liquids (P=0.0001).
ConclusionsIt was found that the real POF time in our hospitals was significantly longer than the modern guidelines, and needs to be corrected.

Due to the important influence of glycemic control on oral health, this study aimed to compare the gingival index and decayed, missing, filled teeth (DMFT) in participants with type 2 diabetes mellitus receiving insulin and metformin.
Materials and MethodsIn this cross-sectional study, 130 participants with type 2 diabetes mellitus treated with insulin and metformin were studied in two groups based on the type of treatment. The information for DMFT and gingival indices were obtained using the oral examination. In the insulin group, participants received insulin Lantus 0.2 unit/kg once daily, and in the metformin group, participants received metformin tablets 500 mg every 12 hours. Glycosylated hemoglobin A1c (HbA1c) was measured by lab test in all participants. Finally, HbA1c, the information of DMFT, and gingival indices were compared between the two groups.
ResultsThe results showed that there were no statistically significant differences in decayed, missed, and restored teeth, as well as the overall DMFT index between the two groups. The gingival index was significantly higher in the insulin group (P=0.046).
ConclusionsGingival health of insulin users is poorer than metformin users, but it seems that type of diabetes treatment does not affect the DMFT index.

Hypovitaminosis D is suggested to be related to the high risk of metabolic disorders and symptoms of schizophrenia. Therefore, this study aimed to evaluate the effect of vitamin D supplementation on cardio-metabolic indices and the severity of symptoms in schizophrenic patients.
Materials and MethodsPatients with schizophrenia (N=42) were randomly assigned to 2 groups, i.e., intervention (2000 IU of vitamin D daily; n=21) and placebo groups (n=21). The intervention was administered for 8 weeks. Anthropometric, clinical, and laboratory measures were assessed at both baseline and end of the trial. The Positive and Negative Syndrome Scale (PANSS) was performed to assess the schizophrenia symptoms.
ResultsVitamin D supplementation leads to a significant decrease in low-density lipoprotein cholesterol (LDL-C) levels (P=0.006). In addition, a significant improvement was found in the PANSS negative subscale score (PANSS-NSS) and PANSS total score (PANSS-TS; P=0.005 and P=0.015, respectively). At the baseline, there was a significant negative correlation between PANSSNSS, PANSS positive subscale score (PANSS-PSS), and PANSS-TS with serum levels of vitamin D (r=-0.42, P=0.010; r=-0.34, P=0.041; and r=-0.47, P=0.004, respectively).
ConclusionsVitamin D supplementation may have helpful efficacy on some cardio-metabolic indices and schizophrenia severity

This study aimed to determine the relationships between endometrial compaction and pregnancy outcome in patients receiving artificial endometrial preparation for frozen embryo transfer (FET) cycles.
Materials and MethodsThis prospective cohort study was performed in a university-affiliated fertility clinic from March 2020 to March 2021. The eligible women undergoing their first or second FET cycle and having the top grading cleavage stage embryos were enrolled. All patients received the same endometrial preparation regime. The alteration in endometrial thickness (EMT) between the day of progesterone initiation and the day of embryo transfer (ET) was measured using consecutive transvaginal sonography. The patients were divided into three groups based on the percentage of endometrial compaction (i.e., the difference of EMT at end of the estrogen-only phase and after three days of progesterone administration (ET day) divided by the EMT on the terminal day of the estrogen-only exposure).
ResultsOverall, 300 eligible women were evaluated and only 27.3% (82/300) of the studied cycles showed ≥5% compaction, whereas 72.6% (218/300) either expanded or showed minimal compaction. The clinical and ongoing pregnancy rates in group 2 (any expansion) were significantly higher than those in groups 1 and 3 (P=0.002 and P=0.01, respectively). Multivariable logistic regression test indicated that the cycles with any expansion in ET were independently associated with 3.1 times improvement in clinical pregnancy rate in comparison to those with any compaction (P=0.002).
ConclusionGross endometrial compaction occurred in one-third of FET cycles with no significant positive effect on pregnancy outcomes after cleavage-stage ET.

Suicide is a serious public health problem, especially among students as active members of the community. The present study aimed to determine the correlation among personality characteristics, family functioning, and suicidal ideation in students of Shahid Beheshti University of Medical Sciences in Tehran, Iran in 2018.
Materials and MethodsThe population of this descriptive correlational study included all 675 students of Shahid Beheshti University of Medical Sciences, from whom 244 students were selected using stratified random sampling. The required data was collected using four questionnaires, including demographic characteristics, personality traits, family functioning, and Beck Scale for Suicidal Ideation (BSSI). To analyze data, we used multiple linear regression and the Statistical Package for the Social Sciences (SPSS, version 22).
ResultsExamination of personality traits suggested that the correlation between psychosis and suicidal thoughts was positive and significant (P<0.05). The correlation coefficients between the components of extraversion-introversion, agreeability, and responsibility and suicidal ideation were negative and significant (P<0.05). There was also a positive and significant relationship between all components of family functioning and suicidal ideation (P<0.05).
ConclusionsEffective steps can be taken to prevent suicide among students through providing optimal psychological healthcare and periodic screening of students in terms of suicidal thoughts and mental disorders.

This study aimed to evaluate the effect of carvacrol and treadmill exercise on oxidative stress and testis structure in streptozotocin (STZ)-induced diabetic rats.
Materials and MethodsIn this experimental study, the diabetes was induced using a single intraperitoneal (IP) injection of STZ (50 mg/kg). The rats were assigned to five groups, namely a control group, a diabetic control group, a diabetic group receiving daily carvacrol at a dose of 75 mg/kg, diabetic groups performing treadmill exercise, and a diabetic group performing daily treadmill exercise and receiving carvacrol. After covering the treatment period, all rats were anesthetized and their blood sample were taken. Then the serum levels of oxidative stress markers were measured, the testicles and epididymis were removed, and the sperm parameters were assessed.
ResultsThe treatment of diabetic rats with carvacrol and treadmill exercise effectively improved testis tissue damage, sperm parameters, glucose, and insulin plasma levels (P=0.001). In diabetic rats, the level of malondialdehyde (MDA) increased while the activity of superoxide dismutase (SOD) and catalase (CAT) enzymes decreased in the testes tissue (P=0.001). However, when carvacrol administration (75 mg/kg) was combined with treadmill exercise, these parameters were significantly rectified (P<0.05).
ConclusionIn sum, administering carvacrol and performing treadmill exercise were effective in improving the sperm parameters and testicular oxidative damage caused by diabetes.
