Delirium risk factors in hospitalized patient: a comprehensive evaluation of underlying diseases and medications in different wards of a large Urban Hospital Center in Iran.

BACKGROUND: Delirium is a neurobehavioral syndrome, which is characterized by a fluctuation of mental status, disorientation, confusion and inappropriate behavior, and it is prevalent among hospitalized patients. Recognizing modifiable risk factors of delirium is the key point for improving our preventive strategies and restraining its devastating consequences. This study aimed to identify and investigate various factors predisposing hospitalized patients to develop delirium, focusing mostly on underlying diseases and medications. METHOD: In a prospective, observational trial, we investigated 220 patients who had been admitted to the internal, emergency, surgery and hematology-oncology departments. We employed the Confusion Assessment Method (CAM) questionnaire, The Richmond Agitation Sedation Scale (RASS), the General Practitioner Assessment of Cognition (GPCOG), demographic questionnaire, patient interviews and medical records. Multivariate logistic regression models were used to analyze the predictive value of medications and underlying diseases for daily transition to delirium.; demographics were analyzed using univariate analysis to identify those independently associated with delirium. RESULTS: Two hundred twenty patients were enrolled; the emergency department had the most incident delirium (31.3%), and the surgery section had the least (2.4%); delirium was significantly correlated with older ages and sleep disturbance. Among multiple underlying diseases and the medications evaluated in this study, we found that a history of dementia, neurological diseases and malignancies increases the odds of transition to delirium and the use of anticoagulants decreases the incident delirium. CONCLUSION: Approximately 1 out of 10 overall patients developed delirium; It is important to evaluate underlying diseases and medications more thoroughly in hospitalized patients to assess the risk of delirium.

Oral health-related quality of life in rheumatoid arthritis: a comparative analysis.

BACKGROUND: Compared to the healthy population, the psychological impact of rheumatoid arthritis(RA) on patients' lives could dramatically lower their oral health-related quality of life (OHRQoL). Our goal is to analyze OHRQoL in RA patients and look into the role of disease activity, dental health index, and Temporomandibular disorders score in maintaining their oral health. METHODS: In a cross-sectional comparative study, we compared a sample of 40 RA patients with 40 age- and gender-matched healthy controls in terms of oral health and OHRQoL. Temporomandibular disorders (TMD), number of decayed, filled, or missing teeth (DMFT), and Oral Health Impact Profile (OHIP) were among the oral health factors studied (OHIP-14). This study also looked at the link between the RA disease activity score (DAS28) and oral health factors. RESULTS: RA patients had a significantly higher mean (poorer OHRQol) than healthy controls in total oral function, total psychosocial impact, OHIP-14 sum score, OHIP-14 extent score, TMD score and the number of missed teeth (Mann-Whitney U test, P-value < 0.05). After adjustment for DMFT, only the oral function score of OHIP-14 had a significant correlation with disease activity (Mann-Whitney U test, P-value < 0.05). The TMD sum score significantly correlated with disease activity regardless of adjustment for DMFT (Spearman's Correlation test, P-value < 0.05 for both). The number of decayed teeth and missed teeth showed a positive correlation with increased disease activity (Coefficient = 0.239 and 0.245, P-value < 0.05 for both). CONCLUSIONS: Patients with RA are less satisfied with their oral health than healthy controls. In RA patients, the number of missing teeth and temporomandibular disorders was substantially greater, and the number of missing teeth and temporomandibular diseases increased significantly with increased disease activity. Although OHRQoL was inversely connected with RA activity, after correcting for decaying, missing, and filled teeth, only the oral function score of OHIP-14 exhibited a slight connection to DAS28.

Prevalence of the refractive errors by age and gender: the Mashhad eye study of Iran.

BACKGROUND: Refractive errors are a common eye problem. Considering the low number of population-based studies in Iran in this regard, we decided to determine the prevalence rates of myopia and hyperopia in a population in Mashhad, Iran. DESIGN: Cross-sectional population-based study. PARTICIPANTS: Random cluster sampling. Of 4453 selected individuals from the urban population of Mashhad, 70.4% participated. METHODS: Refractive error was determined using manifest (age > 15 years) and cycloplegic refraction (age ≤ 15 years). Myopia was defined as a spherical equivalent of -0.5 diopter or worse. An spherical equivalent of +0.5 diopter or worse for non-cycloplegic refraction and an spherical equivalent of +2 diopter or worse for cycloplegic refraction was used to define hyperopia. MAIN OUTCOME MEASURES: Prevalence of refractive errors. RESULTS: The prevalence of myopia and hyperopia in individuals ≤ 15 years old was 3.64% (95% CI: 2.19-5.09) and 27.4% (95% CI: 23.72-31.09), respectively. The same measurements for subjects > 15 years of age was 22.36% (95% CI: 20.06-24.66) and 34.21% (95% CI: 31.57-36.85), respectively. Myopia was found to increase with age in individuals ≤ 15 years and decrease with age in individuals > 15 years of age. The rate of hyperopia showed a significant increase with age in individuals > 15 years. The prevalence of astigmatism was 25.64% (95% CI: 23.76-27.51). CONCLUSIONS: In children and the elderly, hyperopia is the most prevalent refractive error. After hyperopia, astigmatism is also of importance in older ages. Age is the most important demographic factor associated with different types of refractive errors.

Evaluation of miR-181b and miR-126-5p expression levels in T2DM patients compared to healthy individuals: Relationship with NF-κB gene expression.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a progressive metabolic disorder whose prevalence is rising very fast across the world. Diagnosis of this disease in early stages (pre-diabetic stage) plays an important role in reducing mortality associated with this disorder. miRNAs, as key players in the pathogenesis of T2DM, have been investigated in several studies. Furthermore, their expression profile changes in the early stages of diabetes mellitus in body fluids such as serum, peripheral blood, and peripheral blood mononuclear cell (PBMC) have been studied. Due to their high stability and the presence of non-invasive sensitive methods for their measurement, such as real-time PCR, they can be used for early diagnosis of T2DM as a biomarker. In this experimental study, the expression levels of miR-181b, miR-126-5p, and NF-κB were measured in patients with T2DM, pre-diabetic subjects, and healthy controls in a Yazd population. MATERIAL AND METHOD: Ninety asymptomatic subjects including 30 T2DM, 30 pre-diabetic, and 30 healthy subjects (diagnosis based on WHO criteria) were included in this study. Real-time PCR was used to measure the expression levels of miR-181b and miR-126-5p. Moreover, the NF-κB expression level was also measured to determine its relationship with these two microRNAs. RESULT: In this study, the expression level of miR-181b and miR-126-p decreased gradually in pre-diabetic as well as T2DM subjects compared to healthy controls. Furthermore, our study showed a significant negative correlation between these two miRNAs and NF-κB for the first time. CONCLUSION: These results introduce these anti-inflammatory miRNAs as powerful tools for early diagnosis of T2DM.

A Novel Mutation in the OFD1 Gene in a Family with Oral-Facial-Digital Syndrome Type 1: A Case Report.

Oral-facial-digital syndrome as heterogeneous developmental conditions is characterized by abnormalities in the oral cavity, facial features and digits. Furthermore, central nervous system (CNS) abnormalities can also be part of this developmental disorder. At least 13 forms of OFDS based on their pattern of signs and symptoms have been identified so far. Type 1 which is now considered to be a ciliopathy accounts for the majority of cases. It is transmitted in an X-linked dominant pattern and caused by mutations in OFD1 gene, which can result in embryonic male lethality. In this study, we present a family suffering from orofaciodigital syndrome type I who referred to Medical Genetics Research Center, Shahid Sadoughi University of Medical Sciences in 2015. Two female siblings and their mother shared a novel 2-base pair deletion (c.1964-1965delGA) in exon 16 of OFD1 gene. Clinically, the sibling had oral, facial and brain abnormalities, whereas their mother is very mildly affected. She also had history of recurrent miscarriage of male fetus.

Epidemiology of oral cavity cancers in a country located in the esophageal cancer belt: a case control study.

INTRODUCTION: As one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer. MATERIALS AND METHODS: Patients with oral cavity cancer who were treated at two tertiary referral centers from January 1999 to January 2009 were included in this study. In addition to demographic data, information regarding personal and family history of head and neck cancer, use of dentures, presence of immune deficiency, consumption of alcohol, and incidence of cigarette smoking was collected. Additionally, a history of opium usage was obtained from the participants in this study. Moreover, an appropriately matched control group was selected for comparisons between the risk factors. RESULTS: A total of 557 patients were entered into this study over a 10-year period, of whom 219 (39.3%) were female and the remaining 338 (60.7%) were male. The tongue was the most common site of cancer and 9% of the patients had a history of opium abuse, but more than half of the patients did not have any recognized risk factors. The incidence and stage of cancer had a significant relationship with cigarette smoking (P= 0.013). CONCLUSION: Tongue cancer in non-smokers is the predominant pattern of oral cavity cancer in Iran.

ANTECEDENTES: La diabetes mellitus tipo 2 (DMT2) es un trastorno metabólico progresivo cuya prevalencia aumenta muy rápidamente en todo el mundo. El diagnóstico de esta enfermedad en estadios iniciales (fase prediabética) tiene un papel importante para reducir la mortalidad asociada con este trastorno. Los miARN, como elementos clave en la patogenia de la DMT2, se han investigado en varios estudios. Además, se han estudiado los cambios de su perfil de expresión en los estadios iniciales de la diabetes mellitus en líquidos corporales como el suero, la sangre periférica y las células mononucleares de sangre periférica (CMSP). Gracias a su elevada estabilidad y a la existencia de métodos sensibles no invasivos para medirlos, como la RCP en tiempo real, pueden utilizarse como biomarcadores para el diagnóstico precoz de la DMT2. En este estudio experimental se determinaron los niveles de expresión de miR-181b, miR-126-5p y NF-kappaB en pacientes con DMT2, sujetos prediabéticos y controles sanos de una población de la ciudad de Yazd. MATERIAL Y MÉTODO: Se incluyeron en este estudio a 90 sujetos asintomáticos, incluidos 30 con DMT2, 30 prediabéticos y 30 sanos (el diagnóstico se basó en los criterios de la OMS). Se utilizó RCP en tiempo real para determinar los niveles de expresión de miR-181b y miR-126-5p. Se midió también el nivel de expresión de NF-kappaB para determinar su relación con estos 2 micro-ARN. RESULTADOS: En este estudio, el nivel de expresión de miR-181b y miR-126-5p descendió gradualmente en los sujetos prediabéticos y con DMT2 comparados con los controles sanos. Además, nuestro estudio mostró por primera vez una correlación negativa importante entre estos 2 miARN y NF-kappaB. CONCLUSIÓN: Estos resultados sugieren que estos miARN antiinflamatorios son herramientas potentes para el diagnóstico precoz de la DMT2
