RESUMEN

Background: Clinical judgment is one of the most important competencies required for safe care, decision-making, and diagnosis in nursing profession. Therefore, it is necessary to examine clinical judgment in nursing care. Existing a standard questionnaire based on cultural and social conditions can accurately evaluate clinical judgment in nurses. Objective: The present study aimed to develop and validate clinical judgment capability questionnaire in nurses. Design: The current research was a sequential exploratory mixed method study. Setting: The teaching hospitals affiliated to Jahrom University of Medical Sciences in the South of Iran in 2023. Participants: Twelve clinical nurses were included in the qualitative part and 181 nurses in the quantitative part. Methods: The study was conducted in two parts: one qualitative and one quantitative. In the qualitative part, the concept of clinical judgment was explored using qualitative content analysis. Then, the initial pool of items was generated to develop a questionnaire. In the quantitative part, psychometric properties of the questionnaire were evaluated including face, content, and structure validity and reliability (internal consistency and stability). Results: After examining the psychometric properties, 22 items were developed for the final questionnaire. The results of factor analysis led to the extraction of four factors, including noticing, interpreting, responding, and reflecting. The internal consistency of the questionnaire was confirmed with a Cronbach's alpha coefficient of 0.95 and its stability with an intraclass correlation coefficient of 0.84. Conclusion: The developed 22-item questionnaire is a valid and reliable tool for assessment of clinical judgment capability in nurses.

RESUMEN

BACKGROUND: The human papillomavirus (HPV) infection may affect the miRNA expression pattern during cervical cancer (CC) development. To demonstrate the association between high-risk HPVs and the development of cervix dysplasia, we examined the expression patterns of hsa-miR-194-5p and hsa-miR-195-5p in Pap smear samples from southeast Iranian women. We compared samples that were HPV-positive but showed no abnormality in the cytological examination to samples that were HPV-positive and had severe dysplasia. METHODS: Pap smear samples were obtained from 60 HPV-positive (HPV-16/18) patients with histologically confirmed severe dysplasia (cervical intra-epithelial neoplasia (CIN 3) or carcinoma in situ) and the normal cytology group. The expression of hsa-miR-194-5p and hsa-miR-195-5p was analyzed by real-time quantitative PCR, using specific stem-loop primers and U6 snRNA as the internal reference gene. Clinicopathological features were associated with miRNA expression levels. Furthermore, functional enrichment analysis was conducted using in silico tools. The Kaplan-Meier survival method was also obtained to discriminate survival-significant candidate miRNAs in CC, and receiver operating characteristic (ROC) curves were constructed to assess the diagnostic value. RESULTS: Compared to HPV-positive cytologically normal Pap smear samples, hsa-miR-194-5p and hsa-miR-195-5p relative expression decreased significantly in HPV-positive patients with a severe dysplasia Pap smear. Kaplan-Meier analysis indicated a significant association between the miR-194 decrease and poor CC survival. In essence, ROC curve analysis showed that miR-194-5p and miR-195-5p could serve as valuable markers for the development of cervix dysplasia in individuals who are positive for high-risk HPVs. CONCLUSIONS: This study revealed that hsa-miR-194-5p and hsa-miR-195-5p may possess tumor suppressor capabilities in the context of cervical dysplasia progression. However, it remains uncertain whether these microRNAs are implicated in the transition of patients with high dysplasia to cervical cancer. We also showed the potential capability of candidate miRNAs as novel diagnostic biomarkers related to cervical dysplasia progression.

RESUMEN

Canavan disease is a leukodystrophy caused by ASPA mutations that diminish oligodendroglial aspartoacylase activity, and is characterized by markedly elevated brain concentrations of the aspartoacylase substrate N-acetyl-l-aspartate (NAA) and by astroglial and intramyelinic vacuolation. Astroglia express NaDC3 (encoded by SLC13A3), a sodium-coupled transporter for NAA and other dicarboxylates. Astroglial conditional Slc13a3 deletion in aspartoacylase-deficient Canavan disease model mice ("CD mice") reversed brain NAA elevation and improved motor function. These results demonstrate that astroglial NaDC3 contributes to brain NAA elevation in CD mice, and suggest that suppressing astroglial NaDC3 activity would ameliorate human Canavan disease.

RESUMEN

Unexpected poor ovarian response (UPOR) occurs when nine or fewer oocytes are retrieved from a young patient with normal ovarian reserve. Bone morphogenetic protein15 (BMP15) and growth differentiation factor 9 (GDF9) are two oocyte-specific factors with pivotal role in folliculogenesis. The aim of this study was to assess the relation between BMP15 and GDF9 variants with UPOR. Hundred women aged ≤ 39 with AMH ≥ 1.27 IU/ml participated as UPOR and normal ovarian responders (NOR) based on their oocyte number. Each group consisted of 50 patients. After genomic DNA extraction, the entire exonic regions of BMP15 and GDF9 were amplified and examined by direct sequencing. Western blotting was performed to determine the expression levels of BMP15 and GDF9 in follicular fluid. Additionally, in silico analysis was applied to predict the effect of discovered mutations. From four novel variants of BMP15 and GDF9 genes, silent mutations (c.744 T > C) and (c.99G > A) occurred in both groups, whereas missense variants: c.967-968insA and c.296A > G were found exclusively in UPORs. The latter variants caused reduction in protein expression. Moreover, the mutant allele (T) in a GDF9 polymorphism (C447T) found to be more in NOR individuals (58% NOR vs. 37% UPOR (OR = 2.3, CI 1.32-4.11, p = 0.004).The novel missense mutations which were predicted as damaging, along with other mutations that happened in UPORs might result in ovarian resistance to stimulation. The mutant allele (T) in C447T polymorphism has a protective effect. It can be concluded that there is an association between BMP15 and GDF9 variants and follicular development and ovarian response.

RESUMEN

BACKGROUND: Aminoacylase-1 deficiency (ACY1D) is an autosomal recessive rare inborn error of metabolism, which is caused by disease-causing variants in the ACY1. This disorder is characterized by increased urinary excretion of specific N-acetyl amino acids. Affected individuals demonstrate heterogeneous clinical manifestations which are primarily neurologic problems. In neuroimaging, corpus callosum hypoplasia, cerebellar vermis atrophy, and delayed myelination of cerebral white matter have been reported. AIMS: Finding disease-causing variant and expanding imaging findings in a patient with persistent basal ganglia involvement. METHODS: Whole-exome sequencing was performed in order to identify disease-causing variants in an affected 5-year-old male patient who presented with neurologic regression superimposed on neurodevelopmental delay following a febrile illness. He had inability to walk, cognitive impairment, speech delay, febrile-induced seizures, truncal hypotonia, moderate to severe generalized dystonia, and recurrent metabolic decompensation. RESULTS: All metabolic tests were normal except for a moderate metabolic acidosis following febrile illnesses. The results of serial brain magnetic resonance imaging (MRI) at ages 1 and 4.5 years revealed persistent bilateral and symmetric abnormal signals in basal ganglia mainly caudate and globus pallidus nuclei with progression over time in addition to a mild supratentorial atrophy. A homozygous missense variant [NM_000666.3: c.1057C>T; p.(Arg353Cys)] was identified in the ACY1, consistent with aminoacylase-1 deficiency. Variant confirmation in patient and segregation analysis in his family were performed using Sanger sequencing. CONCLUSIONS: Our findings expanded the phenotype spectrum of ACY1-related neurodegeneration by demonstrating persistent basal ganglia involvement and moderate to severe generalized dystonia.

RESUMEN

The tomato (Solanum lycopersicum L.) is an annual vegetable cultivated all over the world. It faces biotic and abiotic stresses, such as salinity, in arid and semiarid regions. Investigating the relationship between physiological and economic traits, such as fruit yield, under stress conditions is necessary to identify tolerant genotypes. This study was conducted to identify tolerant tomato families according to the relationship between several important physiological, morphological and phenological traits. Twenty S3 families were cultivated in a factorial experiment (factor1: families and factor2: normal conditions and salinity stress) based on a randomized complete block design with three replications in 2019. Twenty physiological, agronomic and fruit-quality-related traits were investigated. Analysis of variance was used to prove the existing effective genetic diversity. Genetic diversity and the relationships between traits were graphically shown using heatmap clustering. Finally, genetic parameters, such as Pearson's correlation, trait stability index and heritability were used to calculate the mathematical value of families using the Modified Analytical Hierarchy Process. Families exhibited different behaviours under normal and stress conditions. The tolerant families responded physiologically to the salt stress. Therefore, they reduced both cell membrane degradation and photosynthesis disruption by increasing proline, lycopene, carotenoid and sugar content. Therefore, fewer reductions in morphological traits were observed in these families. The most important traits based on the selection strategy were lycopene content, K+/Na+ ratio, days to flowering and biological yield. In addition, three families, H4/T/30/1, H1/T/12/5 and H1/T/47/4, were selected as the most suitable alternatives to construct the breeding population of the next generation.

RESUMEN

Background: The COVID-19 epidemic control has become a global challenge and many contributing variables are still unknown to policymakers. This case-cohort study was conducted to investigate the risk factors of mortality in COVID-19 patients. Methods: This case-cohort study was conducted on 956 samples in Ardakan and Meybod counties, Yazd Province, between February 20 and May 20, 2020. The data collection tool was a researcher-made questionnaire. Data analysis was done using descriptive statistics and paired t-test, chi-square, and logistic regression analysis. Results: Of a total cohort population of 993 in Ardakan and Meybod counties, 435 were assigned to the control group and 521 were assigned to the case group. The results of outcome analysis showed that 14.4% of the patients in the case group and 11.5% of the patients in the control group died. According to the results of logistic regression analysis in COVID-19 patients, each one-year increase in age increased the risk of mortality by 6% (HR = 1.06, p < 0.001), each one-day increase in the hospital stay increased the risk of death by 8% (HR = 1.08, p < 0.001). Moreover, the presence of cardiovascular disease, chronic neurological disease, and chronic pulmonary disease increased the risk of death. The patients who underwent mechanical ventilation had 85% less chance of survival (HR = 0.15, p < 0.001). Conclusions: The results showed a higher mortality rate in the elderly patients as well as those with underlying diseases. Attention should be paid to at-risk and elderly patients in terms of ensuring a healthy diet, improving their self-care practices, and providing long-term medical and healthcare facilities.

RESUMEN

Purpose: A semi-quantitative food frequency questionnaire (FFQ) was developed for use in the Prospective Epidemiological Research Studies in IrAN (PERSIAN Cohort), investigating non-communicable disease risk factors. This study aimed to assess the validity and reproducibility of this FFQ, through food group intake. Methods: Participants, recruited from seven PERSIAN cohort centers, completed the FFQ at the beginning of the study (FFQ1) and at the end (FFQ2), with a 12-month interval in between, during which two 24-h dietary recalls (24 h) were completed each month. Correlation coefficients of the median intake of food groups recorded by the FFQs were compared to those of the 24 h to assess validity, and the two FFQs were compared to assess reproducibility of findings. Results: Overall, data from 978 participants were included in this validation analysis. Of the 26 food groups assessed, Tea, Sugars, Whole/Refined Grains, and Solid Fats/Oils, had the strongest correlations (0.6-0.79), while Red Meat, Chicken and Eggs showed moderate correlations (0.42-0.59). The weakest correlations observed belonged to Fresh fruit Juice and Other Meats (0.23-0.32). Reproducibility was assessed among those who completed both FFQ1 and FFQ2 (n = 848), revealing moderate to strong correlations in all food groups, ranging from 0.42 in Legumes to 0.72 in both Sugar and Sweetened Drinks. Conclusion: The PERSIAN Cohort FFQ is appropriate to rank individuals based on food group intake.

RESUMEN

Corrosion has caused significant annual costs for building construction and civil architectural designs. In this study, Monosodium glutamate (GLU) was proposed as a potential candidate for long-lasting corrosion inhibition to slow down the rate of corrosion in the concrete pore environment. In this regard, the electrochemical and morphological properties of the various GLU concentrated systems between 1 to 5 wt% in the simulated concrete pore solution media were investigated. According to the EIS results, adding 4 wt% of GLU could reduce the mild steel corrosion process by 86% through a mixed inhibition mechanism. Also, the polarization records represented that the samples' corrosion current density was diminished to 0.169 µA cm-2 after the addition of 4 wt% GLU into the harsh environment. Using the FE-SEM method, the growth of the GLU layer over the metal substrate was demonstrated. The results of spectroscopic methods, i.e., Raman and GIXRD, demonstrated that GLU molecules were successfully adsorbed over the surface of the metal. Contact angle test outcomes showed that by increasing the GLU concentration to its optimum level (4 wt%), the surface hydrophobicity was dramatically raised to 62°.

RESUMEN

MXene nanosheets (MXenes), a brand-new classification of two-dimensional (2D) nanomaterials, are assumed to be highly functional components in anticorrosion polymeric systems. In general, MXenes possess many advantageous features that can be utilized to improve the polymeric matrices' anticorrosion performance. In this work, zinc ions (Zn) were deposited on the sulfonated polyaniline (SPANI) that was polymerized on Ti3C2-MXene surfaces (MXP-Zn) in order to achieve a high-performance anticorrosion nanofiller for epoxy coating (EP-MXP-Zn). Field-emission scanning electron microscopy-transmission electron microscopy images, Fourier transform infrared, Raman, X-ray diffraction, UV-vis, derivative thermogravimetry, and thermogravimetric analysis have evidenced the successful characterization of the MXP-Zn nanocomposite. Likewise, the excellent barrier properties of SPANI, in conjunction with the cathodic protection of Zn, resulted in a novel nanocomposite that could mitigate the negative consequences of destructive ions' attack on the metal surface in an aggressive media. Quantitative and qualitative anticorrosion measurements verified the outstanding anticorrosion performance of EP-MXP-Zn over time in severe conditions. According to the electrochemical impedance spectroscopy assessments, the |Z0.01 Hz| value for EP-MXP-Zn was 1010.04 Ω cm2, which was over 105 times greater than that of neat EP (104.66 Ω cm2) over a 6-week period of immersion in a 3.5 wt % NaCl solution.

RESUMEN

Background: The South Asian Association for Regional Cooperation (SAARC) covers Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. We conducted a comparative analysis of the trade-off between the health policies for the prevention of COVID-19 spread and the impact of these policies on the economies and livelihoods of the South Asia populations. Methods: We analyzed COVID-19 data on epidemiology, public health and health policy, health system capacity, and macroeconomic indicators from January 2020 to March 2021 to determine temporal trends by conducting joinpoint regression analysis using average weekly percent change (AWPC). Results: Bangladesh had the highest statistically significant AWPC for new COVID-19 cases (17.0; 95% CI = 7.7-27.1, P < 0.001), followed by the Maldives (12.9; 95% CI = 5.3-21.0, P < 0.001) and India (10.0; 95% CI = 8.4-11.5, P < 0.001). The AWPC for COVID-19 deaths was significant for India (6.5; 95% CI = 4.3-8.9, P < 0.001) and Bangladesh (6.1; 95% CI = 3.7-8.5, P < 0.001). Nepal (55.79%), and India (34.91%) had the second- and third-highest increase in unemployment, while Afghanistan (6.83%) and Pakistan (16.83%) had the lowest. The rate of change of real GDP had the highest decrease for Maldives (557.51%), and India (297.03%); Pakistan (46.46%) and Bangladesh (70.80%), however, had the lowest decrease. The government response stringency index for Pakistan had a see-saw pattern with a sharp decline followed by an increase in the government health policy restrictions that approximated the test-positivity trend. Conclusions: Unlike developed economies, the South Asian developing countries experienced a trade-off between health policy and their economies during the COVID-19 pandemic. South Asian countries (Nepal and India), with extended periods of lockdowns and a mismatch between temporal trends of government response stringency index and the test-positivity or disease incidence, had higher adverse economic effects, unemployment, and burden of COVID-19. Pakistan demonstrated targeted lockdowns with a rapid see-saw pattern of government health policy response that approximated the test-positivity trend and resulted in lesser adverse economic effects, unemployment, and burden of COVID-19.

RESUMEN

Background and Aims: The diabetes is one of the most common noncommunicable diseases, the prevalence of which is increasing worldwide. This study aimed to determine the prevalence, and correlates the factors of diabetes in the setting of Shahedieh cohort study in Yazd, Iran. Method: The present study is a cross-sectional study conducted on the data of the initial stage of Shahdieh Yazd cohort. This study examined the data of 9747 participants aged from 30 to 73 years. The data included demographic, clinical, and blood test variables. Multivariable logistic regression was used to calculate the adjusted odds ratio (OR), and the risk factors of diabetes were studied. Meanwhile, population attributable risks for diabetes were estimated, and reported. Results: The prevalence of diabetes was 17.9% (CI95%: 17.1-18.9); 20.5% in women, and 15.4% in men. Based on the results of multivariable logistic regression showed female sex (OR = 1.4, CI95%: 1.24-1.58), waist-hip ratio (OR = 1.4, CI95%: 1.24-1.58), high blood pressure (OR = 2.1, CI95%: 1.84-2.4), cardiovascular diseases (CVD) (OR = 1.52, CI95%: 1.28-1.82), stroke (OR = 1.91, CI95%: 1.24-2.94), age (OR = 1.81, CI95%: 1.67-1.96), hypercholesterolemia (OR = 1.79, CI95% triglyceride: 1.59-2.02), and low-density lipoprotein (LDL) (OR = 1.45, CI95%: 1.4-1.51), as risk factors for diabetes. Among the modifiable risk factors, high blood pressure(52.38%), waist-to-hip ratio (48.19%), the history of stroke (47.64%), hypercholesterolemia (44.13%), history of CVD (34.21%), and LDL ≥ 130 (31.03%) had the greatest population-attributable, respectively. Conclusion: The results showed that some of the main determinants of diabetes are the modifiable risk factors. Therefore, implementing early detection, and screening programs for people at risk and preventive measures, such as lifestyle modification programs, and control of risk factors can prevent this disease.

RESUMEN

BACKGROUND: Selection is one of the essential skills whereby breeders reduce the population size and increase the chance of success. Various selection methods with special applications have been developed. Superior genotypes are assessed according to interesting traits, including univariate, multivariate, phenotypic, genotypic, etc. METHODS: Mathematical calculation of the traits' importance based on the genetic makeup of investigated population (average degree of dominance/additive involved in the action of genes) and arbitrary genetic parameters is functional. In this paper, a general model for multivariate selection has been presented whereby the selection can be made for (a) more than one interesting trait, (b) the trait(s) with complex inheritance, (c) finding superior genotypes from among a large-scale population, (d) finding superior genotypes in segregating generations and (f) finding tolerant genotypes to stresses. This model is developed based on biometric concepts in four steps. MATLAB script is provided for the model, and users can easily apply that to identify the most suitable genotypes after data collection according to the breeding purposes. RESULTS: The main features of this model are simplicity, precision, repeatability, and speed (improving several traits simultaneously). All the steps and the analysis of the results are explained step by step in a case study.

RESUMEN

The fungicide mancozeb increases oxygen-free radicals in the central nervous system. As an antioxidant, L-carnitine protects DNA and cell membranes from damage caused by oxygen-free radicals. The present study investigated how L-carnitine affected the acoustic startle response (ASR) in rats exposed to mancozeb. In this experimental study, male Wistar rats were gavaged orally with mancozeb (500, 1000, and 2000 mg/kg), L-carnitine (100, 200, and 400 mg/kg), or L-carnitine (200 mg/kg) + mancozeb (500 mg/kg) three times in 1 week. In the sham group, saline (0.9%, 10 mL/kg) was gavaged at a volume equivalent to that of the drugs. The control group did not receive any treatment. The results showed that locomotor activity and the percentage of prepulse inhibition in the mancozeb groups decreased compared to the sham group while these parameters increased in the L-carnitine group (200 mg/kg) compared to sham rats. In conclusion, mancozeb may increase the risk factor for cognitive diseases such as schizophrenia in people exposed to it while pretreatment with L-carnitine can attenuate the toxic effect.

RESUMEN

Duchenne muscular dystrophy (DMD) is associated with distinct mitochondrial stress responses. Here, we aimed to determine whether the prospective mitochondrial-enhancing compound Olesoxime, prevents early-stage mitochondrial stress in limb and respiratory muscle from D2.mdx mice using a proof-of-concept short-term regimen spanning 10-28 days of age. As mitochondrial-cytoplasmic energy transfer occurs via ATP- or phosphocreatine-dependent phosphate shuttling, we assessed bioenergetics with or without creatine in vitro. We observed that disruptions in Complex I-supported respiration and mH2O2 emission in D2.mdx quadriceps and diaphragm were amplified by creatine demonstrating mitochondrial creatine insensitivity manifests ubiquitously and early in this model. Olesoxime selectively rescued or maintained creatine sensitivity in both muscles, independent of the abundance of respiration-related mitochondrial proteins or mitochondrial creatine kinase cysteine oxidation in quadriceps. Mitochondrial calcium retention capacity and glutathione were altered in a muscle-specific manner in D2.mdx but were generally unchanged by Olesoxime. Treatment reduced serum creatine kinase (muscle damage) and preserved cage hang-time, microCT-based volumes of lean compartments including whole body, hindlimb and bone, recovery of diaphragm force after fatigue, and cross-sectional area of diaphragm type IIX fiber, but reduced type I fibers in quadriceps. Grip strength, voluntary wheel-running and fibrosis were unaltered by Olesoxime. In summary, locomotor and respiratory muscle mitochondrial creatine sensitivities are lost during early stages in D2.mdx mice but are preserved by short-term treatment with Olesoxime in association with specific indices of muscle quality suggesting early myopathy in this model is at least partially attributed to mitochondrial stress.

RESUMEN

INTRODUCTION: Multiple sclerosis is associated with decrease in health-promoting behaviors (HPBs) and require appropriate nursing interventions. Telenursing can play an important role in education of patients during the COVID-19 pandemic in which face-to-face education is limited. This study aimed to investigate the effect of self-care education with telenursing approach on HPBs in patients with MS. MATERIALS AND METHODS: In this clinical trial, 68 patients with MS were selected using simple random sampling from Jahrom MS Society and randomly assigned to the intervention (n = 34) and control (n = 34) groups. In the intervention group, educational sessions were held three days a week for six weeks. Data were collected using demographic information and Walker's Health-Promoting Lifestyle questionnaires before and immediately after the intervention. Data were analyzed by Mann-Whitney and Wilcoxon tests using SPSS software (Ver. 21). RESULTS: Based on the findings, immediately after the intervention, the mean score of HPBs was significantly higher (p = 0.005) in the intervention group (145.38 ± 26.66) than the control group (129.18 ± 22.35). The means of nutrition, exercise, health responsibility, and stress management were significantly different between the intervention and control groups immediately after the intervention (p < 0.05). CONCLUSION: results this study indicated that self-care education with telenursing approach was effective on HPBs in patients with MS. It can be beneficial to employ as an educative-supportive approach in MS patients.

RESUMEN

Background: Burn is one of the most significant injuries in industrial and developing societies and is one of the most important traumas leading to hospitalization. The aim of this study was to identify the epidemiology, geographical distribution, and outcome of electric burns in Fars province and to present the distribution map. Methods: In this descriptive-analytical study, the study population involved all electrical burn victims admitted to Amir al-Momenin and Ghotbeddin Hospitals from 2008 to 2019 in Fars province in the south of Iran. Data were analyzed using SPSS software version 22. Results: Among a total of 246 patients, the average age was 30.78 ± 11.07. The highest frequency among educational levels was among under-diploma patients (38.6%), and the majority were employed (87.4%). Also, most of the patients were from urban areas (70.3%). The majority of burn incidences occurred at the workplace (57.7%). Also, among the high voltage patients, 25 patients (30.9%) had an amputation, while among low voltage only 12 patients (16.2%) had an amputation. Non-surgical treatment was applied in 68 (28%) cases, while Escharotomy was performed in 28 (11.4%) patients. There was also a statistically significant association between burn voltage and amputation (P= 0.039). Conclusion: Based on our report, the rate of electrical burn injuries in Iran is still high, which underlines the need for stronger efforts in effective prevention, such as better public education and the establishment of strict regulations regarding the distribution and use of electricity.

RESUMEN

Background: Lapse has been one of the major challenges in the treatment of drug dependence sometimes leading to its relapse. Objectives: The aim of this study was to determine the lapse rate in drug dependent patients as for the 2 methods of methadone maintenance treatment (MMT) and buprenorphine maintenance treatment (BMT) in Yazd city. Methods: In this cross-sectional study, 626 female and male patients who had referred to 5 SUD treatment centers in Yazd and had been treated with methadone and buprenorphine maintenance were studied. Participants were divided into 2 groups of MMT and BMT and were evaluated based on lapse within 6 months. Results: In this study, 60.9% of patients were treated with methadone but the rest were treated with buprenorphine. Overall, 33.1% of patients lapsed (35.2% for methadone and 29.8%for buprenorphine). Lapse in methadone treatment was correlated with age, occupational status, and duration of treatment (P < .05); it failed to correlated with any other demographic and clinical characteristics (P > .05). Lapse rate in buprenorphine treatment was also related to marital status and the drug used (P < .05). The mean dose of buprenorphine consumed showed no significant relationship with lapse (P > .05). The results demonstrated that given the low dose, lapse stood higher in the buprenorphine group than the methadone group; however, as to high dose, the buprenorphine group showed lower lapse than the other group. Conclusions: In regard with the high rate of lapse, it is recommended to consider the factors related to the 2 methods of treatments, and provide counseling and training programs to lower lapse in the patients.Ethics Committee (REC) approval code: IR.SSU.REC.1394.158.
