RESUMEN
BACKGROUND: Thyroid cancer is one of the most common malignancies of the endocrine system, the fifth most common malignancy in women worldwide, and the second most common cancer in women over 50 in 2019. It is the sixth most common cancer in both sexes and the third most common cancer in women in Guilan province. This study was conducted to describe the geographic variation and investigate any changes in the trend of the thyroid cancer incidence rate. METHODS: This study was conducted on the data of the Guilan University of Medical Sciences cancer registration system. The crude and age-standardized incidence rate was calculated per 100,000 person-years. Joinpoint regression analysis evaluated the time trends and annual percent changes (APC). The incidence rate was estimated separately for each city and high-risk areas were shown on the province map using GIS software. RESULTS: 1742 cases of thyroid cancer (83.7â¯% in women and 16.3â¯% in men) were registered in Guilan province from 2009 to 18. The incidence of thyroid cancer was 5.1-fold higher in women than men. The results of the joinpoint regression analysis showed that the age-standardized incidence rate of thyroid cancer in both sexes has increased significantly over ten years (APC: 26.4; 95â¯%CI: 22.5-30.4), (P-valueâ¯<â¯0.001). In our study, Astaneh-ye Ashrafiyeh, Lahijan, and Langarud cities were identified as high-risk areas of the province for both sexes. CONCLUSION: The trend of incidence of thyroid cancer in Guilan province is increasing. Also, a wide geographical variation was found in the incidence of thyroid cancer.

INTRODUCTION AND AIMS: Phototherapy is the most common treatment modality of neonatal hyperbilirubinemia. We aimed to evaluate the therapeutic effect of oral Ursodeoxycholic Acid (UDCA) on indirect hyperbilirubinemia in term neonates undergoing phototherapy. MATERIALS AND METHODS: This randomized controlled clinical trial was performed on 106 full-term neonates with jaundice who were admitted to the neonatal ward of 17 Shahrivar Hospital in Rasht, Iran. The neonates were randomly assigned to two groups of intervention (10 mg/kg UDCA+phototherapy) and control (phototherapy alone). Total serum bilirubin (TSB) was measured at the time of admission, during first 12, 24, and 48 hours after admission and at the time of discharge. The duration of hospitalization and side effects were also assessed in both groups. IBM SPSS Statistics for Windows, version 20 was used to analyze the data. RESULTS: Results showed that in the intervention group, 28 (52.8%) of neonates were boys with the mean age of 5.1±1.25 days. While, in the control group 29 (54.7%) of them were boys with the mean age of 5.19±2.26 days. Bilirubin levels in both groups decreased significantly after hospitalization (at 12, 24 and 48 hours) (P <0.001). The mean of bilirubin at 12, 24 and 48 hours in the intervention and control groups were 17.1, 13.2, 10.2 mg / dl and 17.1, 14.2 and 11.3 mg / dl, respectively. At the time of discharge, TSB in the former compared to the latter group was significantly reduced (7.74± 1.39 vs. 8.67±1.35) (P = 0.001). In addition, the duration of hospitalization was considerably shorter in the intervention compared to the control group (P = 0.038) and no side effects were observed. CONCLUSIONS: Administering UDCA plus phototherapy reduced TSB and length of hospital stay with proper safety and efficacy. Therefore, it seems that this combination can be an appropriate treatment modality in neonatal hyperbilirubinemia.

Background: Despite many advances, patients with a poor ovarian response to stimulation are one of the most important and challenging factors of infertility. Chronological and ovarian ages are two effective factors responsible for poor response to assisted reproduction treatment. The purpose of this study was to determine the effect of age and AMH level on the in vitro fertilization (IVF) outcomes in participants with a reduced ovarian reserve. Methods: In this retrospective cross-sectional study, 210 participants with anti-Mullerian hormone (AMH) < 1.1 ng/ml were included. The effect of age and AMH on pregnancy outcomes including dominant follicle count, serum estradiol level on the day of trigger administration, number of metaphase II (MII) oocytes, number of embryos, biochemical pregnancy, clinical pregnancy, abortion and live birth rate were evaluated. Results: The number of dominant follicle (p < 0.001), MII oocyte (p < 0.001), grade A (p < 0.001) and B (p < 0.001) embryos, serum estradiol level (p < 0.001), gonadotropin level ( p< 0.001), AMH (p = 0.001), biochemical pregnancy (p = 0.007), clinical (p = 0.01) pregnancy, and live birth rate (p = 0.003) were higher in participants younger than 35 years old. In univariable logistic regression, the chance of retrieving more than 3 oocytes in individuals over 35 years old was 97.1% lower than in individuals younger than 35 years old (p < 0.001). Conclusion: It has been concluded that the higher clinical pregnancy and live birth rate in participants younger than 35 years can be due to the higher AMH level in this group. Under the same conditions of AMH and other variables, age can affect the number of retrieved oocytes.
RESUMEN
Background and Aim: Increased maternal age at the time of pregnancy and labor is believed to have potential complications. To evaluate the effects of maternal age on the mode of delivery among nulliparous women with term pregnancies who underwent labor induction. Methods: In this retrospective cohort study, 313 women with the gestational age of at least ≥37 weeks, were enrolled. They were divided based on their maternal ages as: Group A < 35 years old (y/o) and Group B ≥ 35 y/o patients. Demographic features and other variables (i.e., past medical history, social history, indications and methods of labor induction, causes of cesarean delivery) were recorded from patients' files. Final outcomes were categorized as: primary (i.e., rate of cesarean section: C/S) and (b) secondary (i.e., duration of labor, postpartum complications, neonatal variables). All data were analyzed by the SPSS ver.21 software. Results: Median and interquartile ranges of gestational age were not significantly different, comparing the two groups (p = 0.415), although these variables were significantly different regarding maternal height among the two groups (p = 0.007). There was a significant relationship between the methods of labor induction among the two groups (p = 0.005). There was a prominent statistical relationship between (a) C/S deliveries and also (b) indications of C/S among the two groups (p = 0.004 and p = 0.033, respectively). Univariate logistic regression test revealed maternal age groups, neonatal weight, and history of underlying diseases had significant results (p < 0.05). Conclusions: Increased maternal age is associated with higher rates of CS among nulliparous women with term pregnancies who underwent labor induction.
RESUMEN
Background: The substantial increasing trend of binge drinking is a global alarm. Our aim was to undertake a systematic review and meta-analysis of cross-sectional studies to explore the association of current smoking with binge drinking among adults. Methods: We systematically searched Web of Knowledge; PubMed; Scopus; Embase and Ovid (MEDLINE, EMBASE, PsycARTICLES, PsycINFO, PsycEXTRA, and PsycTests) (from inception to 27 May 2020) databases to identify cross-sectional studies of the association between current smoking and binge drinking. Study screening, data extraction, and methodological quality assessment were all carried out by two independent authors. Adjusted odds ratio (AOR) was pooled with 95% confidence intervals (CI) using random effects model in the meta-analysis, followed by the investigation of the heterogeneity via Q-test and I 2 statistic. We assessed publication bias using a funnel plot, the Egger's, and Begg's tests. Results: We identified 3,171 studies and included nine cross-sectional studies with 64,516 participants. A significant association was found between current smoking and binge drinking among both genders (AOR = 2.97; 95% CI = 1.98 to 4.45; I 2 = 90.5%). Subgroup analysis showed that this association among women, men, Caucasians, and Asians/Africans were (AOR = 3.68; 95% CI = 1.03 to 13.18; I 2 = 98.9%), (AOR = 2.53; 95% CI = 1.87 to 3.42; I 2 = 73.1%), (AOR = 1.36; 95% CI: 1.01-1.83, I 2 = 47.4%), and (AOR = 3.93; 95% CI: 2.99-5.17, I 2 = 61.3%), respectively. There was no evidence of publication bias. Conclusion: Current smoking is associated with binge drinking and can be used for identifying and screening binge drinkers. Moreover, this association is stronger among men, and Asians/Africans. This meta-analysis estimation was limited to English-language studies, and the full text of about 3.5% of reports for retrieval was not found, then generalization of the results should be done with caution.
RESUMEN
BACKGROUND: Burn trauma is a significant health problem that has physical, psychological, and economic reaction on affected patients. Burn patients have different length-of-stay (LOS) due to the complexity of the injury itself. This study aimed to find factors affecting the LOS and cost of burn patients (2017-2018) in Guilan province, north of Iran. MATERIALS AND METHODS: This cross-sectional study includes all 899 hospitalized burn patients who were admitted for the first time (first visit). Data about cost, LOS, and demographic variables were extracted from the hospital registry system. Data were analyzed using t-test, ANOVA, and Linear regression by SPSS 22 software. RESULTS: Nearly 62% of the burn patients were male, and 38% were female. Hot liquid or vapor were the leading causes for burns hospitalization (n = 345; 39.07%). The majority of patients (n = 465; 52.31%) were at level three of burn (total thickness). The upper limb that included head, neck, shoulder, back, hand (45.44%), lower limb (38.25%), multiple or total body (11.36%) were the most organs that were affected by burning. Direct medical costs for patients varied from 0 to 18,550 US$, which was 1489 US$ on average. Patients' length of stay ranged from 1 to 47 days, which was 3.22 days on average. CONCLUSION: The result showed Adverse consequences burned hot liquid and hot steam burns most common reason that it is important to take preventative methods for this type of patient. Improved patients with the third level cost more and stay longer. Other factors such as underlying disease, urbanity, used antibiotics, sex, and insurance coverage can also be decisive. The burnt percentage also has a direct and significant relationship with medical costs and length of stay. Insurance organization has a direct and significant relationship with the length of stay. Also there was a direct relationship between multiple burns and the patients' length of stay and hospitalization costs.
RESUMEN
BACKGROUND: Thyroid dysfunction can affect fertility and miscarriage risk by affecting the process of follicular growth, embryo development, implantation, and placental formation. It has been suggested that thyroid disorders are associated with ovarian reserve by affecting the follicular process. The aim of the present study was to investigate the relationship between thyroid hormone levels and ovarian reserve. METHODS: Three hundred fourteen women with infertility due to various etiologies were enrolled in this study (172 individuals with Anti-Mullerian hormone (AMH) level ≥ 1.1 ng/ml and 142 individuals with AMH < 1.1 ng/ml). Serum levels of follicle-stimulating hormone (FSH), estradiol (E2) on day 2-4 of menstrual cycles, AMH, Thyroid-stimulating hormone (TSH), and thyroxine (free T4) were evaluated. RESULTS: In participants with age over 35 years, median TSH level in women with AMH < 1.1 ng/ml was significantly higher than those with AMH ≥1.1 ng/ml (P-value =0.037). There was no significant difference in body mass index (BMI) in patients with age older than 35 years and younger than 35 years sub-groups based on AMH level (P-value = 0.102, and P-value = 0.909 respectively). With one unit increase in TSH level, the odds of having AMH < 1.1 ng/ml increases by 1.25 times or by 25% (P-value =0.017). Receiver operator characteristic (ROC) curve analysis showed a TSH cut-off point of 1.465 mIU/L in participants over 35 years in identifying decreased AMH level. CONCLUSION: Our study supports the relationship between TSH level and ovarian reserve so that with an increase in TSH from a certain level is associated with a decrease in ovarian function.
RESUMEN
BACKGROUND: Due to the physiological changes in the body during pregnancy, the increased susceptibility to viral infections during this period and also the high prevalence of coronavirus disease 2019 (COVID-19) in the Guilan province, Iran, this study aimed to evaluate risk factors, clinical symptoms, laboratory findings and imaging of pregnant mothers with COVID-19. METHODS: In this descriptive study, 70 pregnant women aged 17-41 years with COVID-19 who were hospitalized from early March to late April 2020 were enrolled. Sampling was performed by census and from all hospitals in Guilan. The research instruments included a researcher-made questionnaire, including demographic characteristics, clinical symptoms, medical examinations, and paraclinical results. Data were analyzed with SPSS version 16. Frequency and percent were used to describe qualitative variables; for quantitative variables, if they were normally distributed, mean and standard deviation were used, and if they were non-normal, median and interquartile range (IQR) were used. RESULTS: The most severe symptoms recorded in mothers at the time of hospitalization were fever (47%), shortness of breath (16%) and cough (15%), respectively. One of 68 (1%) was in the severe stage of the disease and two mothers (2%) were in critical condition and admitted to the intensive care unit and finally died. Fifty-five of 66 women (83%) had lymphopenia, 22 of 42 (52%) tested positive on PCR, and 30 of 33 (90%) had an increase in lactate dehydrogenase (LDH) levels.Results showed that 15 of 32 patients who gave birth had preterm delivery (46%). CONCLUSION: The most common manifestations of the disease in pregnant women were fever, cough and shortness of breath, and in some cases muscle pain. The most common laboratory finding in infected mothers was lymphopenia. Complications of pregnancy and childbirth in women included an increase in cesarean delivery.

The web portal Medfloss.org lists over 360 medical free/libre and open source software (MEDFLOSS) projects. These projects are described with the help of a self-developed nomenclature. Due to inconsistencies, the nomenclature shall be replaced by HITO, the Health IT Ontology. HITO is developed iteratively based on different use cases. This paper aims to describe methods and results of the second HITO use case in which HITO is extended to improve the description, retrieval and comparisons of MEDFLOSS projects on Medfloss.org. We use a mixed-methods approach to add concepts and relationships to describe MEDFLOSS precisely. The resulting HITO version stresses functional descriptions based on features and supported enterprise functions, rather than just describing technical characteristics. However, describing a larger number of MEDFLOSS projects requires the commitment of the community.

Health informatics as a young, interdisciplinary discipline lacks a unified terminology in some areas. This is especially true when trying to properly describe health informatics interventions developed and deployed to improve quality and efficiency of patient care. We aim at developing a health IT ontology which allows systematically describing health IT interventions. To achieve this, we combine a deductive and an inductive approach. First results are promising and may later be extended by a folksonomy.

BACKGROUND: There is no published study evaluating the performance of cumulative sum (CUSUM) algorithm on meningitis data with limited baseline period. This study aimed to evaluate the CUSUM performance in timely detection of 707 semi-synthetic outbreak days. METHODS: Simulated outbreaks were generated using syndromic data on fever and neurological symptoms from Mar 2010 to Mar 2013 in Hamadan Province, the west of Iran. The performance of CUSUM algorithms, numbered from 1 to 11, in timely detection of outbreaks was measured using sensitivity, specificity, false alarm rate, likelihood ratios and area under the receiver operating characteristics (ROC) curve. RESULTS: The highest amount of sensitivity was related to algorithm11 (CUSUM(3-9 D11)) and it was 52% (95% CI: 49%, 56%). Minimum amount of false alarm rate was related to CUSUM(1-7 D5) algorithm equal to 8% (95% CI: 5, 10) and the best amount of positive likelihood ratio was related to CUSUM(1-7 D4) equal to 4.97. CUSUM(1-7 D1) has the best performance with AUC curve equal to 73% (95 CI%: 70%, 76%), as well. CONCLUSION: The used approach in this study can be the basis for applying CUSUM algorithm in conditions that there is no access to recorded baseline data about under surveillance diseases or health events.
RESUMEN
Gamma-glutamyl carboxylase (GGCX) mutations have been reported in patients with a pseudoxanthoma elasticum (PXE)-like phenotype, loose redundant skin, and multiple vitamin K-dependent coagulation factor deficiencies. We report on the clinical findings and molecular results in 13 affected members of two families who had a uniform phenotype consisting of (PXE)-like skin manifestations in the neck and trunk, loose sagging skin of the trunk and upper limbs, and retinitis pigmentosa confirmed by electroretinographies in 10 affected individuals. There were no coagulation abnormalities. Molecular investigations of the ATP-binding cassette subfamily C member 6 did not yield causative mutations. All 13 affected family members were found to be homozygous for the splice-site mutation c.373+3G>T in the GGCX gene. All tested parents were heterozygous for the mutation, and healthy siblings were either heterozygous or had the wild type. We suggest that the present patients represent a hitherto unreported phenotype associated with GGCX mutations. Digenic inheritance has been suggested to explain the variability in phenotype in GGCX mutation carriers. Consequently, the present phenotype may not be explained only by the GGCX mutations only but may be influenced by variants in other genes or epigenetic and environmental factors.
