Cytoplasmic CCR7 (CCR7c) Immunoexpression Is Associated with Tumor Invasion in Gastric Cancer.

Background : This study investigates the CCR7 chemokine receptor's prognostic value in gastric cancer and its relationship to metastasis. Materials and Methods : Normal and adjacent tumor cells in 70 patients with gastric cancer were evaluated for CCR7 expression using immunohistochemical staining. The prognostic values of high and low levels of expression of CCR7 were also evaluated by multivariate and univariate analyses. Results : Analysis indicated high expression of CCR7 in 52.9% of tumor tissue. Moreover, high expression of CCR7 was significantly related to metastasis of lymph nodes (p = 0.00). In addition, high expression of CCR7 had a positive correlation to the disease stage (p = 0.00), age of ≥50 years (p = 0.019), male gender (p = 0.024), vascular involvement (p = 0.009), histology of tumor adenocarcinoma (p = 0.00), and poor tumor differentiation (p = 0.00). However, the high expression of the CCR7 marker was not related to the tumor size. Conclusion : Based on our results, CCR7 expression in gastric cancer can be considered a clinical prognostic indicator in patients with gastric cancer.

Viral contamination of acrylic resin removable denture bases in patients with COVID-19: A cross-sectional study.

STATEMENT OF PROBLEM: Salivary gland ducts are one of the primary targets of severe acute respiratory syndrome coronavirus 2. Moreover, saliva contains minor and major salivary gland secretions and a combination of nasopharyngeal and lung secretions. The acrylic resin bases of complete or partial removable dentures have pores and provide a favorable environment for the growth of microorganisms. PURPOSE: The purpose of this cross-sectional study was to investigate the presence of viral contamination of acrylic resin removable denture bases in patients with coronavirus disease 2019 (COVID-19). MATERIAL AND METHODS: The acrylic resin denture bases (partial and complete) of 29 patients with COVID-19 who underwent treatment in the Infectious Diseases Department of Razi Hospital in Ghaemshahr, Mazandaran, Iran, were evaluated. Samples were collected from the intaglio surface of the prostheses by direct swabbing and coding and were evaluated in a laboratory for the presence or absence of coronavirus. The relationship between hospital polymerase chain reaction (PCR) and denture PCR and the relationship between denture type and denture PCR were evaluated with the Fisher exact test (α=.05). RESULTS: Twenty-nine patients, age range 55 to 85 years, 18 women, 3 with partial dentures and 26 with complete dentures, were evaluated. The hospital PCR test was positive in 28 patients, while the denture PCR test was positive in 4 patients. No significant relationship was observed between the results of hospital PCR and denture PCR in patients with COVID-19 (P=.138). All 4 patients who tested positive for denture PCR had complete dentures. No significant relationship was found between denture type and denture PCR test results in patients with COVID-19 (P>999). CONCLUSIONS: Despite the microporous structure of the acrylic resin base, no statistically significant viral contamination was observed.

Depressive symptoms in men immediately after birth.

OBJECTIVE: Depression is the second leading cause of morbidity worldwide. This study aimed to assess the prevalence and associated risk factors of paternal postpartum depressive symptoms (PPD). METHODS: In a cross-sectional study, via a stratified random and convenience sampling method 591 couples who were referred to Mazandaran primary health centers between 2 and 8 weeks postpartum were recruited from March to October 2017. Couples were screened for depressive symptoms using Edinburgh Postnatal Depression Scale (EPDS). Fathers provided information on socio-demographic characteristics, life events, neonatal stressor, perceived stress (Perceived Stress Scale), social support (Multidimensional Scale of Perceived Social Support), and general health status using General Health Questionnaire (GHQ-12) as well. Data was analyzed using multiple logistic regression. RESULTS: Overall, 93 fathers (15.7%) and 188 mothers (31.8%) reported depressive symptoms above the cut-off EPDS score of 12. In the multiple logistic regression model, older age, maternal depressive symptoms, higher GHQ-12 scores and increased recent life events were related to paternal PPD. A significant inverse association was found between number of children and paternal PPD. CONCLUSION: Depressive symptoms especially in first-time fathers following the birth of a child are not uncommon. Creating opportunities for men to access special health care services, parental education to help adapting to parenthood, screening programs, and psychiatric/psychosocial interventions to decrease suffering of depression for both depressed parents are recommended.

Intralesional Injection of the Measles-Mumps-Rubella Vaccine into Resistant Palmoplantar Warts: A Randomized Controlled Trial.

BACKGROUND: Common resistant-to-therapy warts pose a challenge to both clinicians and patients. Among many destructive and immunotherapeutic options, no single, fully effective treatment has been suggested yet. Many investigations, including those using intralesional antigen administrations, have demonstrated that cellular immunity plays a major role in the clearance of human papilloma virus (HPV) infection. The aim of the present study was to evaluate the effects of the intralesional injection of the measles-mumps-rubella (MMR) vaccine into resistant-to- treatment palmoplantar warts and its complications. METHODS: In this single-blind, randomized, controlled clinical trial, 60 cases with resistant-to-therapy palmoplantar warts referring to the Dermatology Clinic of Bou-Ali Sina Hospital of Sari between June 2015 and 2016 were randomly assigned to 2 equal groups: the MMR Group received intralesional MMR and the Placebo Group was given saline injection. The injections were administered at 2-week intervals until complete clearance was achieved or for a maximum of 5 injections (<5 injections at 2-week intervals). The study protocol was registered in the Iranian Registry of Randomised Clinical Trials (ID: IRCT2016101027636N3), and the statistical analyses were performed using SPSS, version 17.0. The χ2 test and the F-test were used as appropriate, and a P value less than 0.05 was considered statistically significant. RESULTS: Complete clearance was observed in 65.2% (14/23) of the patients presenting with resistant-to-therapy palmoplantar warts in the MMR Group and 23.85% (5/21) in the Placebo Group (P=0.021). Recurrence was not observed in any of the completely cured patients at 6 months' follow-up. CONCLUSION: Intralesional immunotherapy with the MMR vaccine may result in a desirable therapeutic response and can be used as an effective and safe treatment option for palmoplantar warts, particularly persistent ones. Trial Registration Number: IRCT2016101027636N3.

Analyzing Short Message Services Application Effect on Diabetic Patients' Self-caring.

BACKGROUND: Diabetes is the most prevalent metabolic disease with a growing spread rate in word wide. Short message service (SMS) is of the most common public communication networks, which have brought about a broad spectrum of applications like social, cultural and service products in the late decade. The objective of this research is, the investigate of using SMS on diabetes patients self-caring. METHODS: In an interventional study, 228 diabetes patients have been selected from a community charity. With using of random sampling method, they were divided into two groups of 114 subjects as the control and case. The case group was sent messages reminding them about sports, caring foot, taking insulin and oral tablet for 4 weeks via mobile phone. After 4 weeks, a posttest questionnaire was completed. The data analysis was performed using a descriptive statistic, Chi-square, independent t-test, and paired t-test. RESULTS: There are not significant differences between case and control groups before intervention by studied dependent variables (P > 0.05). Performance score mean of taking care of foot, sport and taking oral tablet and insulin in case group before intervention were 29.90, 10, 11.16 and 3.75 respectively and after intervention were 20.11, 41.36, 13.09 and 4.90, respectively. Furthermore, the performance scores mean difference after intervention, taking care of foot (P < 0.001), sport (P < 0.001), taking oral tablet (P = 0.020) was meaningful in case and control groups. CONCLUSIONS: Regarding the study results on using cell phone, to utilize virtual training methods is recommended as an appropriate procedure for different health care, self-caring and follow-up training plans for various groups in society, especially diabetic and chronic patients.

Assessment of Critical Care Provider's Application of Preventive Measures for Ventilator-Associated Pneumonia in Intensive Care Units.

BACKGROUND: The implementation of guidelines for the prevention of Ventilator-associated pneumonia has been shown to have a significant effect in reducing the incidence of VAP. OBJECTIVE: The aim of the present study was to evaluate the implementation of the preventive strategies for VAP in ICUs of university hospitals of Sari, Iran. MATERIALS AND METHODS: This cross-sectional study was carried out in 600 beds/day in the ICUs of university hospitals of Sari from April to June 2012. Sampling was done by availability technique in patients receiving mechanical ventilation in the ICU. The implementation of the preventive measures was assessed by a standard checklist with previously approved validity and reliability. RESULTS: The percentage of implementing each of the measures was as follows: sterile suction, 88.44%; semi-recumbent position, 76.8%; oral hygiene, 58.45%; using heat and moisture exchanges (HMEs), 58%; controlling cuff pressure, 46.8%; hand hygiene, 32.8%; using anti-coagulants, 26.8% and physiotherapy, 25.5%. Closed suction system, continuous drainage of subglottic secretions and kinetic beds were not used at all. CONCLUSION: The overall mean percentage of implementing preventive measures was low and required designing integrated guidelines by considering the conditions of the ICUs in each country, as well as educating and encouraging the staffs to use the recommended guidelines.

Isolation of different species of Candida in patients with vulvovaginal candidiasis from sari, iran.

BACKGROUND: Vulvovaginal Candidiasis (VVC) is a frequent, complex and cumbersome condition that can cause physical and psychological distress for the involved individual. Candida albicans was reported as the most common agent of VVC yet it seems that we are recently encountering changes in the pattern of Candida species in VVC. OBJECTIVES: In this study we assessed different species of Candida isolated from patients with VVC, residing in Sari, Iran. PATIENTS AND METHODS: Two hundred and thirty-four patients with vulvovaginitis were enrolled in this study. Samples were collected by a wet swab. Each vaginal swab was examined microscopically and processed for fungal culture. The identification of Candida species was done by morphological and physiological methods such as culture on CHROMagar Candida media and sugar assimilation test with the HiCandida identification kit (HiMedia, Mumbai, India). RESULTS: Out of 234 patients with vulvovaginitis, 66 (28.2%) patients showed VVC. Of these patients, 16 (24.2%) had recurrent VVC (RVVC). The age group of 20 - 29 year-olds had the highest frequency of VVC (48.5%). Erythema concomitant with itching (40.9%) was the most prevalent sign in VVC patients. Fifty-seven (86.4%) of the collected samples had positive results from both microscopic examination and culture. In total, 73 colonies of Candida spp. were isolated from 66 patients with VVC. The most common identified species of Candida were C. albicans (42.5%), C. glabrata (21.9%) and C. dubliniensis (16.4%). In patients with RVVC and patients without recurrence, C. albicans and non-albicans species of Candida were frequent species, respectively. CONCLUSIONS: The results of our study showed that non-albicans species of Candida are more frequent than C. albicans in patients with VVC. This result is in line with some recent studies indicating that non-albicans species of Candida must be considered in gynecology clinics due to the reported azole resistance in these species.

Comparison of the effects of heparin and 0.9% sodium chloride solutions in maintenance of patency of central venous catheters.

BACKGROUND: Occlusion of central venous catheters is one of the limiting factors in using them. Heparinized saline solution is the standard solution used for keeping the catheters open. OBJECTIVES: This study aimed to determine the effect of heparin saline solution and normal saline in maintenance of patency of central venous catheters. PATIENTS AND METHODS: This double-blind study was performed on 84 patients of intensive care unit who had central venous catheters. The patients were randomly divided into two groups of heparin saline receivers and normal saline receivers. In the heparin group after each drug injection into the lumen, 3 mL of heparin saline solution was injected in the catheter as well. The other group only received 10 mL of normal saline instead. The catheters were examined for blood return and flushing every eight hours for 21 days. Data was analyzed using SPSS software version 20 and descriptive and analytic statistics were studied. RESULTS: There was no significant difference in the rate of flushing (P = 0.872) and possibility of taking blood samples from catheters (P = 0.745) in the two groups of heparin and normal saline receivers. Furthermore, using heparin had no effect on prolonging the survival of catheters. CONCLUSIONS: Considering possible side effects of heparin and the increase in treatment charges and the fact that using heparin did not have a significant effect on patency and survival of catheters in the studied patients, it is recommended to use normal saline solution to maintain the patency of central venous catheters.

Sociocultural factors associated with breast self-examination among Iranian women.

Of the ways to fight breast cancer and reduce deaths hazard due to early detection is one of early detection programs in women's breast self- examination. Examining breast by oneself increase individuals knowledge of her breast health that helps in detecting breast cancer early. Different cultural, social, family and individual factors play roles in women's behavior about breast self- examination applying PEN-3 model in this study is to analyze factors influencing on breast self-examination. The research is a descriptive- analytical, cross-sectional type. Research community consists of women at fertility age of 20-49 in sari. Sample volume is 415 individuals and sampling method is cluster method. In this study, a 50-item questionnaire based on PEN-3 was used. Questions were answered by Likert scoring method. Questionnaire was gathered by personal presence of questioners. Data was analyzed via descriptive statistics and logistic regression methods. Based on the study findings, the most significant positive behaviors related to perceptual factors included effectiveness of disease background in family and relatives (73%), believing in breast self- examination for pursuing health (93%) and the most important negative behaviors were shyness and modesty (83.9%) and increased worry (78.9%). The most remarkable positive behaviors regarding enabling factors covered the skill to do breast examination oneself (35.2%), the availability of health and therapeutic centers (80.7%) and the most significant negative behavior was being busy and lack of time (85.3%). The most important positive behavior about nurturing factors included family consent (68.9%) and the most significant negative one was the inappropriate treatment of health and therapeutic personnel (61.8%). In this study, there is a meaningful difference between employment ages, education with PEN-3 model constituents. Since behaviors due to enabling and nurturing perceptual factors have been important in doing or not doing breast self- examination; thus its worth to take measures to plan some educational and administrative intervention programs about women breast cancer early detection through sufficient knowledge of influential sociocultural factors.

Procrastination and Self-Efficacy Among Intravenous Drug Users on a Methadone Maintenance Program in Sari City, Iran, 2013.

BACKGROUND: Self-efficacy is the belief that one has the ability to implement the behaviors needed to produce a desired effect. There has been growing interest in the role of self-efficacy as a predictor and/or mediator of treatment outcome in a number of domains. Procrastination is a self-regulatory failure, defined as the voluntary delay of an intended course of action despite expecting to be worse off for the delay. Behavioral procrastination is a self-sabotage strategy that allows people to shift blame and avoid action; the decisional procrastination strategy is to put off making a decision when dealing with conflicts or choices. Procrastination has a great role in quitting drug addiction. OBJECTIVES: The aim of this study was to determine the relationship between procrastination and self-efficacy and other factors among intravenous drug users. PATIENTS AND METHODS: This cross-sectional study was conducted on 178 intravenous drug users in the behavioral disease counseling, health center in Sari city, Mazandaran province, Iran, in 2013. The samples were selected through census sampling, descriptive and inferential statistics were used to measure the properties of distribution that depicts a set of data shown as frequency distribution tables, while for the mean and standard deviation, chi-square, Fisher and Spearman-Brown coefficients were used to analyze the data. RESULTS: The mean age of the participants was 43 years. Seventy-two percent of them were married and opium was the first drug used. The first substance used in them was 54% of opium, 33% cannabis and 5% alcohol and 79% smoking. The reason of the first drug use in 32% of the subjects was temptation and in 10% a friend's influence. The mean age of the first drug use was 23 years, and the frequency was 2 times per day. All of them had relapse at least once. Seven percent of them currently use other materials (2% crystal, 5% alcohol and opium and crack) both in methadone treatment. Behavioral procrastination in 60.5% of them and decisional procrastination in 62% is from low to average range. There was a significant relationship between relapse and self-efficacy as well as between self-efficacy and the age of the first drug use, drug dose, and procrastination for treatment, marriage, employment and job. Also, the relationship between behavioral procrastination and self-efficacy was significant and inverse. CONCLUSIONS: This study found a significant difference between procrastination and self-efficacy as well as other related factors. It is important to include drug users and the society organizations representing them in every stage of the governmental policy and program development process to make them responsive to the needs of the community.

Impact of Comorbid Ischemic Heart Disease on Short-Term Outcomes of Patients Hospitalized for Acute Exacerbations of COPD.

BACKGROUND: Ischemic heart disease (IHD) is a leading cause of mortality and morbidity in patients with COPD. The contribution of IHD to acute outcomes in patients with acute exacerbation of COPD (AECOPD) is not known in detail. The present study assessed the effect of comorbid IHD on length of stay (LOS), risk of intensive care unit (ICU) admission and death as indicators of the short-term outcomes for patients hospitalized for AECOPD. MATERIALS AND METHODS: Medical records of patients hospitalized for AECOPD from September 2008 to March 2014 were reviewed. Data extracted from patient records regarding the presence of comorbidities and the markers of disease severity were analyzed using logistic regression for ICU admission and mortality, the Kaplan-Meier method, log rank test and Cox regression for LOS. RESULTS: Of 507 separate admissions, 146 episodes (28.8%) occurred in patients with IHD. The median LOS was 7 days [interquartile range (IQR) 6, 11] in patients with IHD versus 6 days (IQR 5, 8) for patients without IHD. After adjustment for confounders, LOS was found to be 26% longer (p=0.033) for patients with IHD. The adjusted odds ratio for the risk of ICU admission and death in patients with IHD was 2.97 and 3.86, respectively. CONCLUSION: Patients hospitalized for AECOPD with comorbid IHD had longer LOS, greater risk for ICU admission and death. It seems that this group is a particular COPD subtype with a more severe degree of COPD and poorer acute outcomes that may influence optimal management.

Factors associated with post-surgical delirium in patients undergoing open heart surgery.

OBJECTIVE: The objective of the present study is to determine the incidence of delirium and the associated factors in patients undergoing open heart surgery. METHOD: This is an Analytic-descriptive study conducted on 404 patients undergoing elective open heart surgery in Fatemeh Zahra Heart Center, Sari, over the period of 6 months from July to December 2011. Sampling was achieved in a nonrandomized targeted manner and delirium was assessed using NeeCham questionnaire. A trained nurse evaluated the patients for delirium and completed the risk factor checklist on days 1 to 5 after surgery. Data analyses were accomplished using survival analysis (Kaplan-Meier and Cox regression) on SPSS software version 15. RESULTS: We found that variables, including ventilation time, increased drainage during the first 24 hours, the need for re-operation in the first 24 hours, dysrhythmias, use of inotropic agents, increased use of analgesics, increased arterial carbon dioxide, lack of visitors, and use of physical restrainers were associated with the development of delirium. In addition, we found a delirium incidence of 29%. CONCLUSION: Diagnosis of cognitive disorders is of utmost value; therefore, further studies are required to clarify the risk factors because controlling them will help prevent delirium.
