Monitoring the utilization and effectiveness of Iron and Vitamin D supplementations program and its predictive factors in high schools' girls in Qom, Iran.

Background: Iron and Vitamin D3 deficiency is one of the major global health problems in teenagers and adolescent population. This study was aimed to monitor the utilization and predictive factors of Iron and Vitamin D Supplementations Program (IVDSP) in high schools' girls. Methods: In a cross sectional study, the pattern of Iron and D3 consumption based on IVDSP on 400 high schools' girl in Qom, Iran assesses. Data collection was used by a reliable and standard researcher based questionnaire and daily, weekly, monthly and seasonally consumption of complementary minerals in schools were gathered. Data analysis conducted using SPSS version 20 (SPSS Inc., Chicago, IL, USA) by chi square, independent t-test and multivariate logistic regression. Results: The mean age of subjects was 15.14 ± 1.52 years and ranged from 12 to 18 years old. The total weekly prevalence of D3 and Iron consumption in high schools' girls was calculated 36.73% and the weekly prevalence of Iron and monthly prevalence of Vitamin D3 consumption was 33.75% and 40.5%, respectively. The most common causes of non-consumption were bad taste 49.31%, Iranian made drug 20.27%, drug sensitivity 19.82% and drug interaction 10.60%, respectively. Conclusions: The inadequate and incomplete rate of IVDSP in Qom was high and more than 60% of distributed supplementations have been wasted. Results showed that students who were participated in educational orientation classes were more successful and eager in Iron and Vitamin D3 consumption. Therefore, more educational explanatory interventions for both students and her parents recommended to increase the efficiency of the program.

Cancer resilience in parents of children with cancer; the role of general health and self-efficacy on resiliency.

Introduction: Cancer in children affect their parents to some stress and worries during treatment process. This study aimed to assess the parental adjustment on the resiliency of parents of children with cancer and its relationship with social support, self-efficacy, and general health. Materials and Methods: In a cross-sectional study, 107 parents of children with cancer were selected by convenience sampling method from the Oncology Departments of Qom Hospitals, Iran. Standard questionnaires including Phillips Social Support, Corner Davidson Resilience, Sheerer Self-Efficacy Inventory, and General Health Questionnaire (GHQ-28) were used for data collection. Pearson's correlation coefficient, Chi-square test, t-test, and multivariate linear regression were used for data analysis in SPSS software. Results: A significant correlation was observed between cancer resilience and social support score (r = 0.285). Multivariate regression model Showed that social support was the most important predictor of cancer resilience (ß =0.723, P = 0.045). In addition, self efficacy (ß =0.356, P = 0.005) showed a direct relationship with cancer resilience. Nevertheless, an inverse association (ß = -0.351, P = 0.025) was observed between GHQ score and cancer resilience in parents of children with cancer. Conclusion: Cancer resilience in families of children with cancer is significantly associated with higher social support, more self-efficacy, and better general health. Interventional programs aimed at increasing family resilience and reducing stress by increasing the social support and self-efficacy in patients' families are helpful and necessary.

CIRCULATING GHRELIN LEVELS AND SUSCEPTIBILITY TO COLORECTAL CÂNCER.

BACKGROUND AND OBJECTIVE: Considering the association between colorectal cancer (CRC) and both insulin resistance and obesity, and the prominent role of ghrelin in these metabolic disorders, we explored whether plasma levels of ghrelin were associated with CRC. Moreover, in the patients with CRC the possible correlations between ghrelin and insulin, insulin resistance, and body mass index (BMI) as an indicator of obesity were examined. METHODS: A total of 170 subjects, including 82 cases with CRC and 88 controls were enrolled in this study. Plasma levels of ghrelin, insulin, and glucose were measured in all the subjects using ELISA and glucose oxidase methods. Furthermore, insulin resistance was assessed by calculating HOMA-IR index. RESULTS: The cases with CRC had decreased ghrelin levels (P<0.001) and a higher HOMA-IR index (P<0.001) than controls. Interestingly, when CRC patients were stratified based on tumor site, lower ghrelin levels and a higher HOMA-IR index were observed in the patients with either colon or rectal cancer vs. controls too. Additionally, there were an age and BMI-independent negative correlation between ghrelin levels and HOMA-IR (r=-0.365, P<0.05), and an age-independent negative correlation between ghrelin levels and BMI (r=-0.335, P<0.05) in the rectal subgroup. CONCLUSION: Our findings support a role for ghrelin in connection with insulin resistance and obesity in CRC susceptibility; however, it needs to be corroborated by further studies.

RESUMO CONTEXTO E OBJETIVO: Considerando a associação entre câncer colorretal (CCR), a resistência à insulina, à obesidade e o papel proeminente da grelina nessas doenças metabólicas, foi explorado se os níveis plasmáticos de grelina estavam associados ao CCR. Além disso, nos pacientes com CCR foram pesquisadas as possíveis correlações entre a grelina, insulina, resistência insulínica e índice de massa corporal (IMC) como indicadores de obesidade. MÉTODOS: Foram incluídos neste estudo 170 indivíduos, sendo 82 com CRC e 88 controles. Os níveis plasmáticos de grelina, insulina e glicose foram medidos em todos os sujeitos utilizando métodos ELISA e glicose oxidase. Além disso, a resistência à insulina foi avaliada pelo cálculo do índice HOMA-IR. RESULTADOS: Os pacientes com CRC apresentaram redução dos níveis de grelina (P<0,001) e maior índice HOMA-IR (P<0.001) do que os controles. Curiosamente, quando os pacientes com CRC foram estratificados com base no local do tumor, níveis mais baixos de grelina e maior índice de HOMA-IR foram observados nos indivíduos com câncer de cólon ou retal versus controles também. Além disso, houve uma correlação negativa entre idade e IMC independente entre os níveis de grelina e HOMA-IR (r=-0,365, P<0,05) e uma correlação negativa independente da idade entre os níveis de grelina e IMC (r=-0,335, P<0,05) no subgrupo retal. CONCLUSÃO: Nossos achados apoiam o papel da grelina em relação à resistência à insulina e à obesidade na suscetibilidade do CRC; no entanto, ela precisa ser corroborada por estudos posteriores.

The effect of dexmedetomidine on decrease of cough, hemodynamic parameters and Ramsay score versus lidocaine during general anesthesia: a randomized clinical trial.

Physiological responses remain common during anesthesia emergence and endotracheal extubation, causing some complications. We aimed to address the effect of dexmedetomidine (DEX) on decrease of cough, hemodynamic parameters and Ramsay score in comparing to lidocaine (LID) during anesthesia. In this double-blinded randomized clinical trial 120 hospitalized patients undergoing general anesthesia were enrolled after obtaining written consent. Block random allocation was used to assign patients into three groups including DEX (intravenous injection; 0.5 µg/kg), LID (1.5 mg/kg), and PBO (10 mL normal saline) at 10 minutes before anesthesia. No statistical significance was uncovered among three groups in blood pressure, oxygen saturation, frequency of laryngospasm and duration of surgery amongst the groups (P > 0.05), but DEX having lower heart rate and cough frequency (P < 0.05). Moreover, the mean of Ramsay score was statistically higher in DEX and LID groups than PBO except at the 50th and 60th minutes after extubation (P < 0.05). Since the mean of Ramsay score was higher in DEX vs. LID groups and reduced heart rate and cough frequency demonstrates in DEX, it seems that DEX could be an appropriate drug on suppressing cough during anesthesia without side effects. The study protocol was approved by the Ethical Committee of Arak University of Medical Sciences by code IR.ARAKMU.REC.1397.140 on August 19, 2018, and the protocol was registered at Iranian Registry of Clinical Trials by code IRCT20141209020258N97 on February 22, 2019.

Adding ursodeoxycholic acid to the endoscopic treatment and common bile duct stenting for large and multiple biliary stones: Will it improve the outcomes?

BACKGROUND: The role of common bile duct (CBD) stenting in the establishment of bile stream in the elderly patients and the ones who are not good candidates for surgery due to not responding to treatments was well documented in previous studies. The current study aimed at investigating the effect of adding Ursodeoxycholic acid (UDCA) to CBD stenting alone in order to reduce the size of large and multiple CBD stones. METHODS: Clinical outcomes including success rates in CBD stones clearance, incidence of pancreatitis, perforation, bleeding, as well as, decrease in size of stones and liver enzymes after a two-month period were assessed in the UDCA + CBD stenting group. RESULTS: A total of 64 patients referring to Shahid Beheshti Hospital in Qom, Iran with multiple or large CBD stones (above three or larger than 15 mm) received standard endoscopic therapies and UDCA + CBD stenting (group B) and controls only received standard endoscopic therapies with only CBD stenting (group A). The mean reduction in the size of stones in group B was significantly higher than that of group A (3.22 ± 1.31 vs 4.09 ± 1.87 mm) (p = 0.034). There was no difference in the incidence rate of complications including pancreatitis, cholangitis, bleeding, and perforation between the two groups (P > 0.05). CONCLUSION: Adding UDCA to CBD stenting, due to decrease in the stone size and subsequently facilitation of the stones outlet, can be considered as the first-line treatment for patients with large and multiple CBD stones. Also, in the cases with large or multi stones may be effective in reducing size and subsequently stone retrieval. Trial registry The study protocol was approved by the Ethics Committee of Qom University of Medical Sciences (ethical code: IR.MUQ.REC.1397.075); the study was also registered in the Iranian Registry of Clinical Trials (No. IRCT20161205031252N8). This study adheres to CONSORT guidelines.

Efficacy of dexmedetomidine-ketamine vs. fentanylketamine on saturated oxygen, hemodynamic responses and sedation in cystoscopy: a doubleblinded randomized controlled clinical trial.

Cystoscopy is a diagnostic and invasive procedure for treatment and follow-up of genitourinary system patients and could be performed with a variety of anesthesia techniques. The study aimed to assess the efficacy of dexmedetomidine-ketamine vs. fentanyl-ketamine on sedation and analgesia for cystoscopy. This double-blind randomized controlled clinical trial enrolled 60 patients undergoing cystoscopy in two groups. Patients were assigned randomly by block random allocation method into dexmedetomidine-ketamine group (1 µg/kg dexmedetomidine) and fentanyl-ketamine group (2 µg/kg fentanyl) receiving ketamine (0.5 mg/kg). Subsequently, mean blood pressure, heart rate, saturated oxygen, respiratory rate, pain intensity, Ramsay score for sedation level, cystoscopy duration, and urologic satisfaction were measured and compared between two groups. Both the groups were similar regarding age, sex and baseline hemodynamic parameters (P > 0.05). Lower heart rate and pain score were revealed in the dexmedetomidine-ketamine group at 25-50 and 30-60 minutes, respectively, after cystoscopy (P < 0.05). Moreover, repeated measure test showed that there was significant difference in trend of respiratory rate and pain score between two groups (P = 0.017) and was lower in dexmedetomidine-ketamine group. The dexmedetomidine-ketamine group relieves pain 30 minutes after cystoscopy with stable hemodynamic parameters during operation. Therefore, dexmedetomidine-ketamine is recommended to be employed for pain relief in subjects undergoing cystoscopy. The study was approved by Ethical Committee of Arak University of Medical Sciences with IR.ARAKMU.REC.1397.108 on July 2, 2018, and registered in Iranian Registry Clinical Trial center with code IRCT20141209020258N105 on April 21, 2019.

Environmental and ecological factors of stomach cancer incidence and mortality: a systematic review study on ecological studies.

OBJECTIVES: Stomach cancer (SC) is one of the most common and deadly types of cancer. It is the third leading cause of cancer deaths worldwide. The effect of environmental and ecological factors in SC have been assessed in some studies. Thus, we aimed to synthesize the environmental and ecological factors of SC incidence and mortality. CONTENT: In this systematic review study, the scientific databases, including Web of Science, Scopus and PubMed, were searched from inception to November 2019 for all primary articles written in English by using relevant Medical Subject Heading (Mesh) terms. Two independent authors conducted the screening process to decide on the eligibility and inclusion of the articles in the study. The third author acted as an arbiter to resolve any disagreements. SUMMARY AND OUTLOOK: A total of 157 potentially relevant articles were identified from the initial search 38 of which met the eligibility criteria; finally, 34 articles were included in the systematic review. The results revealed that soil arsenic exposure, coal and other opencast mining installations, living near incinerators and installations for the recovery or disposal of hazardous waste, installations for the production of cement, lime, plaster, and magnesium oxide, proximity to a metal industry sources, dietary iron, ingested asbestos, farming, arsenic in soil, altitude, organochlorines and environmental exposure to cadmium and lead have positive associations with SC incidence or death. Most of the ecological and environmental factors such as living near the mineral industries, the disposal of hazardous waste, metal industry sources and environmental exposure to cadmium and lead are positively related to SC mortality and incidence. However, solar UV-B, heat index and dietary zinc can be taken into account as protective factors against SC mortality and incidence.

Socio-Economic Status Inequity in Self Rated Health in Patients with Breast Cancer.

AIM: We investigate the evaluation of socio-economic status (SES) inequality on self-rated health (SRH) at women with breast cancer. STUDY DESIGN: Cross-sectional study. METHODS: The current study conducted on all 270 breast cancer patients that were admitted to one of the hospitals of Arak University Medical Sciences (Arak, Iran from April to July 2018) by census (using non-random sampling (accessible sampling). SES was calculated by asset-based questionnaire and Principle Component Analysis (PCA) was performed to estimate the families' SES. Concentration Index (C) and Curve (CC) was used to measure SES inequality in SRH. The data were analysed with Stata software. RESULTS: The number of persons with good SRH by the level of SES was 165 (61.1%) and with poor SRH was 105 (38.9%). The number of persons with good SRH in comparison to same-aged people by level of SES was 135 (50%) and with poor SRH was 135 (50%). Concentration index of SRH in all level of SES was 0.061 (SE = 0.03). Also, Concentration index for SRH in comparison to same-aged people at different levels of SES was -0.044 (SE = 0.03). CONCLUSION: The results of this study showed that there is inequality in SRH in a patient with breast cancer of the richest level of SES.

Respiratory effects of occupational exposure to low concentration of hydrochloric acid among exposed workers: a case study in steel industry.

Occupational exposure to hydrochloric acid in pickling of steel for remove rust or iron oxide scale from iron processing occurs at low concentration. This study aimed to investigate the respiratory symptoms and pulmonary dysfunction caused by exposure to low concentration of hydrochloric acid in acid washing unit in one of the steel industries. A case control study was carried out in the acid washing unit of the cold rolling of the steel industry in 2017. The exposed group included 45 male workers, and another 41 unexposed employees from official employees were enrolled as control group. A questionnaire was used to collect personal and occupational data and pulmonary function tests, including forced vital capacity (FVC), forced expiratory volume in the first second and peak expiratory flow rate followed guidelines given by the American Thoracic Society and measured with a portable calibrated vitalograph spirometer. For determination of acid concentration, 21 breathing zone air samples were collected in accordance with Method 7903 NIOSH. The findings showed that nose sensitivity, throat irritation and shortness of breath were the highest prevalence symptoms among exposed persons (30.4% to 32.6%). Also, the results showed that FVC and forced expiratory volume in the first second had highest and direct or positive correlation with height (0.965 and 0.927, respectively). Age and weight put in the next priorities (P < 0.01). On the other hand, based on the results of multivariate linear regression, exposing to the acid and job history are two main predictor factors for FVC. So that, the exposing to acid, by itself can reduce FVC as 4.386 units. This value is equal to 1.117 for the job history. Exposure to low concentrations of hydrochloric acid alone could increase the risk of respiratory tract damage and pulmonary function disorders. But the extent to which it can cause respiratory complications for occupational exposure is still unknown and requires further study. This study was approved by Ethical Committee of Qom University of Medical Sciences (approval No. IR.MUQ.REC.1397.118) on November 6, 2018.

Efficacy of dexmedetomidine versus remifentanil to blunt the hemodynamic response to laryngoscopy and orotracheal intubation: a randomized clinical trial.

The study aims to compare the efficacy of dexmedetomidine (DEX) vs. remifentanil (REM) to blunt the hemodynamic response to laryngoscopy and orotracheal intubation. Enrolled in a double-blind clinical trial, 124 patients undergoing elective surgery under general anesthesia at Amirkabir Hospital (Arak, Iran), were assigned into four groups equally (31 patients in each group), DEX, REM, DEX-REM, and normal saline (NS), who received intravenous DEX (1 µg/kg), REM (1 µg/kg), their equal mixture (each 0.5 µg/kg, 1 minute before tracheal intubation), and NS, respectively. Then, blood pressure (BP), heart rate (HR), and arterial oxygen saturation (SaO2) were measured on arrival to the operating room, 1 minute before laryngoscopy and tracheal intubation, immediately after intubation, and afterwards every 5 to 15 minutes, and finally the data were analyzed using SPSS 18.0. The groups were same regarding to age, sex and baseline hemodynamic variables including mean of BP (P = 0.157), HR (P = 0.105) and SaO2 (P = 0.366). Tukey post-hoc test showed that there DEX, REM, and a DEX + REM groups was same regarding to MBP and HR, but these hemodynamic responses were higher in NS group than other groups at all time after laryngoscopy and intubation (P < 0.05). Moreover, repeated measure test showed a decreasing trend in MBP and HR in three intervention groups at all time after intubation (P > 0.05). A DEX/REM mixture had the lowest BP and three intervention groups had lower HR than the NS group. A mixture of the drugs used seems to lead to not only a prevented increase in HR and BP during laryngoscopy but also a decreased BP and HR. This study was registered in Iranian Registry Clinical Center with the registration No. IRCT2016092722254N1.

Comparing remifentanil, magnesium sulfate, and dexmedetomidine for intraoperative hypotension and bleeding and postoperative recovery in endoscopic sinus surgery and tympanomastoidectomy.

The study aimed to compare remifentanil, magnesium sulfate, and dexmedetomidine for intraoperative hypotension, bleeding volume, and recovery time in endoscopic sinus surgery and tympanomastoidectomy (TM). A double-blind clinical trial enrolled the patients undergoing endoscopic nasal sinus surgery and TM at Amirkabir Hospital (Arak, Iran), who were randomly assigned into three groups dexmedetomidine (DEX), remifentanil (REM), and magnesium sulfate (MgSO4) to which we intravenously administered 1 µg/kg DEX, an intravenous dose of 1 µg/kg REM, and 40 mg/kg of intravenous MgSO4, respectively. The blood loss, blood pressure (BP), heart ratio (HR), oxygen saturation (SaO2), and recovery time were recorded. Significant differences were found statistically in bleeding rates among all groups (P = 0.0001). The least amount of blood loss (very mild bleeding) was observed at 82.85% in the DEX group. BP and HR were lower in this group than those in the other groups. While recovery score was significantly different in the three groups (P = 0.007), the recovery time was the highest in the DEX group, while the least in the REM group. Based on the present results Dexmedetomidine seems to better prevent from bleeding than the others. Moreover, DEX can cause lower BP and HR in subjects with lower propofol administration, but the recovery time is longer. This study was registered by IRCT2017021114056N11 in Iranian Registry Clinical Center.

Safety and efficacy of N-acetyl-cysteine for prophylaxis of ventilator-associated pneumonia: a randomized, double blind, placebo-controlled clinical trial.

Ventilator-associated-pneumonia (VAP) is characterized by morbidity, mortality, and prolonged length of stay in intensive care unit (ICU). The present study aimed to examine the effect of N-acetyl-cysteine (NAC) in preventing VAP in patients hospitalized in ICU. We performed a prospective, randomized, double-blind, placebo-controlled trial of 60 mechanically ventilated patients at high risk of developing VAP. NAC (600 mg/twice daily) and placebo (twice daily) were administered to NAC group (n = 30) and control group (n = 30), respectively, through the nasogastric tube in addition to routine care. The clinical response was considered as primary (incidence of VAP) and secondary outcomes. Twenty-two (36.6%) patients developed VAP. Patients treated with NAC were significantly less likely to develop clinically confirmed VAP compared with patients treated with placebo (26.6% vs. 46.6%; P = 0.032). Patients treated with NAC had significantly less ICU length of stay (14.36 ± 4.69 days vs. 17.81 ± 6.37 days, P = 0.028) and less hospital stay (19.23 ± 5.54 days vs. 24.61 ± 6.81 days; P = 0.03) than patients treated with placebo. Time to VAP was significantly longer in the NAC group (9.42 ± 1.9 days vs. 6.46 ± 2.53 days; P = 0.002). The incidence of complete recovery was significantly higher in the NAC group (56.6% vs. 30%; P = 0.006). No adverse events related to NAC were identified. NAC is safe and effective to prevent and delay VAP, and improve its complete recovery rate in a selected, high-risk ICU population.

Trends in epidemiology of Hepatitis B and C Infections in Ilam Province: National Notifiable Diseases Surveillance System data.

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the main causes of severe liver failure worldwide. This study was conducted to evaluate the incidence rate and trend of these infections over six successive years from 2008 to 2013 in Ilam Province, western Iran. METHODS: We studied the registered data of HBV and HCV based on the National Notifiable Diseases Surveillance System in Ilam Province from 2008 to 2013. Incidence rate per 100,000 populations was estimated for HBV and HCV infections through location, years and age groups of patients. RESULTS: The overall incidence rate per 100,000 populations from 2008 to 2013 for HBV infection was 9.57, 5.83, 16.26, 12.44, 21.89 and 13.93, respectively. The corresponding values for HCV infection were 0.55, 0.72, 1.44, 2.69, 1.24 and 1.93, respectively and these trends for both the HBV and HCV infections were increasing. The major distribution of HBV and HCV infections was 25-44 years of age. Both HBV and HCV infections were more common in males, urban areas and married patients. Forty-one percent of cases were carriers and history of surgery was the common risk factor. CONCLUSIONS: Our results showed that HBV and HCV are prevalent in the middle-age group. Despite effective vaccination against hepatitis B, optimized blood donor screening and better sterilization procedures for blood products, trend of HBV and HCV in Ilam are increasing. Further studies should address the role other risk factors in the trend of HBV and HCV.

Concomitant neurogenic and vascular thoracic outlet syndrome due to multiple exostoses.

We report a rare case of multiple hereditary exostosis where patient presented with bilateral base of neck exostoses with concurrent compression of brachial plexus and subclavian artery and vein. The patient was a young 26-year-old woman with chief complaints of pain in the left upper extremity, paresthesia in the left ring and little finger, and weakness in hand movement and grip. On referral, history, physical examination, radiological imaging, and electrodiagnostic tests evaluated the patient. Due to severe pain and disability in performing routine activities, surgical intervention was necessary. In the current case, the patient had thoracic outlet syndrome with concomitant venous, arterial, and neurogenic sub types. Radial pulse returned and pain associated with brachial plexus compression was resolved after the surgery.

Endotracheal intubation in patients with difficult airway: using laryngeal mask airway with bougie versus video laryngoscopy.

Airway management is essential for safe anesthesia and endotracheal intubation is the most important procedure by which critically ill patients can be better managed, especially if done quickly and successfully. This study aimed to compare the techniques of intubation through laryngeal mask airway (LMA) using a bougie versus video laryngoscopy (VL) regarding to intubation success and the quality of intubation indices in patients with difficult airways. This randomized clinical trial was performed on 96 patients aged 16-76 years with Mallampati class 3 or 4 who underwent elective surgery. Once the demographics were recorded, patients were randomly divided into two groups and the first group intubated with VL, and the second group intubated through laryngeal mask using a bougie. Then vital signs, arterial oxygen saturation, the time required for successful intubation, and ease of intubation were recorded. Here t-tests, chi-square, Fisher exact tests, and analysis of variance for repeated measurement were used to analyze the data in SPSS software. The overall success rates of intubation in VL and LMA groups were 46 (96%) and 44 (92%), respectively. The mean duration of intubation for the LMA and VL groups was 18.70 ± 6.73 and 14.21 ± 4.14 seconds, respectively (P < 0.001). Moreover, visual analogue scale score for pain in throat was significantly lower in VL group than LMA (1.65 ± 0.76 vs. 1.33 ± 0.52). Moreover, easy intubation in bougie group was 50%, while the easy intubation in VL was 73% (P = 0.023). In addition, incidence of cough was 31% in the LMA with bougie group and 9% in VL group (P = 0.005). The VL technique is an easier method and has a shorter intubation time than LMA using bougie, and causes a lower incidence of coughing, laryngospasm in patients that need intubation. Moreover, cough and discomfort in the throat tend to be less in VL, and the LMA could be used as replacement of VL in hard situations.

Effect of intravenous anesthesia with propofol versus isoflurane inhalation anesthesia in postoperative pain of inguinal herniotomy: a randomized clinical trial.

Postoperative pain is a common problem after inguinal herniotomy. We aimed to compare the intravenous anesthesia effects of propofol and isoflurane inhalation anesthesia on postoperative pain after inguinal herniotomy. In a randomized clinical trial, 102 eligible patients were selected based on inclusion and exclusion criteria and were randomly divided in two groups. In the first group, propofol was used for the maintenance of anesthesia, while isoflurane was used in the second group. The patient's heart rate, systolic and diastolic blood pressure and oxygen saturation before, during and after surgery, recovery time and postoperative pain were measured immediately, 2, 4 and 6 hours after surgery and compared between two groups. T-test, and repeated measurement test were used for statistical analysis. No statistically significant differences were observed in heart rate, blood pressure and oxygen saturation levels between the two groups (P > 0.05). Propofol has higher effect in easing postoperative pain of patients than isoflurane, but no difference in postoperative complications, including chills, nausea and vomiting, occurs in both two groups. Propofol is effective in declining the postoperative pain of patients after anesthesia in comparison with isoflurane. Moreover, due to the antioxidant, anti-inflammatory and analgesic properties of propofol, it is preferred to isoflurane and the authors recommended it to be used.

Comparing the efficacy and safety of laryngeal mask airway, streamlined liner of the pharyngeal airway and I-gel following tracheal extubation.

Adverse events following surgical operations are common complications due to removal of tracheal tube in contrast to the tracheal intubation. Awareness about the new methods and strategies for tracheal tube extubation is necessary for a safe and successful extubation. Therefore, we aimed to assess the safety and efficacy of laryngeal mask airway (LMA), streamlined liner of the pharyngeal airway (SLIPA) and I-gel in extubation time of tracheal tube. A one-single randomized clinical trial was conducted in 105 eligible patients in three groups including LMA, SLIPA and I-gel. The patients were under surgery after general anesthesia with propofol (2-3 mg/kg) and fentanyl (1-2 µg/kg). Hemodynamic responses and extubation consequences including coughing rate, laryngospasm, airway obstruction, apnea, breath holding and straining of patients, vomiting, and need for re-intubation were recorded every 5 minutes since inserting of supraglottic airway devices (SADs) until patients restore consciousness. Analysis of data was conducted in SPSS software by analysis of variance (ANOVA) and ANOVA for repeated measurements tests. The overall successful insertion was 100% for LMA and I-Gel and this rate was 97.1% for SLIPA method. A significant decrease was observed in trend of hemodynamic responses in all three groups. Nevertheless, the MBP was lower in LMA group and lower HR was observed in I-Gel and higher HR occurred in SLIPA (P < 0.05). Three groups was same statistically regarding sore throat, vomiting, coughing, breath holding, apnea, laryngospasm, and re-intubation need (P > 0.05). However, the incidence rate of apnea, and laryngospasm, as well as re-intubation need in SLIPA group was 2.9%, respectively. LMA, I-GEL and SLIPA could be considered as useful and safe devices for ventilation control after tracheal tube removal at the end of operation. Three devices were same regarding to sore throat, vomiting, coughing, and breath holding. However, LMA showed lower side effects while SLIPA was related to more occurrences of apnea, laryngospasm, and re-intubation need.

Protection behaviors for cytotoxic drugs in oncology nurses of chemotherapy centers in Shiraz hospitals, South of Iran.

CONTEXT: The use of antineoplastic agents for the treatment of cancer is an increasingly common practice in hospitals. As a result, workers involved with handling antineoplastic drugs may be accidentally exposed to these agents, placing them at potential risk for long-term adverse effects. This study aimed to determine the occupational protection status of clinical nursing staff exposed to cytotoxic drugs. SUBJECTS AND METHODS: The study was designed as an analytic descriptive survey. The research settings took place in six centers of chemotherapy in Shiraz, Iran. The participants were 86 nurses who worked in oncology units and administered cytotoxic drugs. Data were collected using a questionnaire and a checklist which was developed by the investigators to determine occupational protection status of clinical nursing staff exposed to cytotoxic drugs. Percentage calculations and the independent samples t-test were used to see the general distribution and analysis of data. To statistically analyze of the data, SPSS software (version 16) was applied. RESULTS: The mean age of participants was 30.52 ± 6.50 years and 66.27% of the nurses worked on inpatient oncology wards. The mean practice score was 21.1 ± 3.76 that ranged from 12.5 to 31. The independent samples t-test showed the outpatient nurses were weaker in practice (17.2 ± 2.52) in comparison with university hospitals (23.35 ± 3.02, P < 0.001). Occupational protection status of clinical nursing staff exposed to cytotoxic drugs especially during administration and disposal of medicines was poor and rarely trained with this subject and was observed under the standard conditions. CONCLUSIONS: There is deficiency in the understanding and related protection practices of clinical nursing staff vocationally exposed to cytotoxic drugs. It is recommended that all clinical nursing staff should receive full occupational protection training about these matters and the authorities provide standard conditions of oncology wards.

Protecting effect of gabapentin for nausea and vomiting in the surgery of cesarean after spinal anesthesia.

BACKGROUND: Nausea and vomiting are the most common effects after cesarean delivery with spinal anesthesia that was associated with problems such as pneumonia, delay in patient discharge, electrolyte abnormalities, and the maternal dissatisfaction. OBJECTIVES: The aim of this study was to evaluate the effects of gabapentin in preventing nausea and vomiting after spinal anesthesia in cesarean delivery. PATIENTS AND METHODS: This study as a double-blind clinical trial was done on 200 candidates of cesarean with a random distribution. Patients without cardiovascular diseases and in 1 and 2 American Society of Anesthesiologists were divided into two groups. Treatment group received 600 mg capsule (gabapentin) 1 h before surgery and the control group received placebo. The severity of nausea and vomiting were evaluated according to 4 Scores every hour to 4 h after the withdrawal of mother from the recovery section. RESULTS: In this study, there is no significant difference in demographic information between these two groups. In the 1(st) h, there is a significant difference between the severity of nausea and vomiting in these two groups, but there is not a significant difference between 2 and 4 h after surgery. However, the incidence of nausea between the two groups shows a significant correlation. CONCLUSIONS: A single dose of gabapentin 1 h before cesarean delivery decreases the incidence of nausea and vomiting after surgery.
