We developed and pilot tested our eConsent framework to provide a personalized consent experience whereby users are guided through a consent document that utilizes avatars, contextual glossary information supplements, and videos, to facilitate communication of information.

The eConsent framework includes a portfolio of eight features, reviewed by community stakeholders, and tested at two academic medical centers.

Early adoption and utilization of this eConsent framework have demonstrated acceptability. Next steps will emphasize testing efficacy of features to improve participant engagement with the consent process.

To enhance the performance evaluation of Clinical and Translational Science Award (CTSA) hubs, we examined the utility of advanced bibliometric measures that go beyond simple publication counts to demonstrate the impact of translational research output.

The sampled data included North Carolina Translational and Clinical Science Institute (NC TraCS)-supported publications produced between September 2008 and March 2017. We adopted advanced bibliometric measures and a state-of-the-art bibliometric network analysis tool to assess research productivity, citation impact, the scope of research collaboration, and the clusters of research topics.

Totally, 754 NC TraCS-supported publications generated over 24,000 citation counts by April 2017 with an average of 33 cites per article. NC TraCS-supported research papers received more than twice as many cites per year as the average National Institute of Health-funded research publications from the same field and time. We identified the top productive researchers and their networks within the CTSA hub. Findings demonstrated the impact of NC TraCS in facilitating interdisciplinary collaborations within the CTSA hub and across the CTSA consortium and connecting researchers with right peers and organizations.

Both improved bibliometrics measures and bibliometric network analysis can bring new perspectives to CTSA evaluation via citation influence and the scope of research collaborations.

A new competency-based job framework was implemented for clinical research professionals at a large, clinical research-intensive academic medical center. This study evaluates the rates of turnover before and after implementation of the new framework. Turnover in this workforce (as with most) is costly; it contributes to wasted dollars and lost productivity since these are highly specialized positions requiring extensive training, regardless of experience in the field.

Trends in employee turnover for 3 years prior to and after the implementation of competency-based job framework for clinical research positions were studied using human resources data. Employee demographics, turnover rates, and comparisons to national statistics are summarized.

Employee turnover within the clinical research professional jobs has decreased from 23% to 16%, a 45% reduction, since the implementation of competency-based job framework.

The new jobs and career ladders, both of which are centered on a competency-based framework, have decreased the overall turnover rate in this employee population. Since little is known about the rates of turnover in clinical research, especially in the academic medical setting, the results of this analysis can provide important insights to other academic medical centers on both employee turnover rate in general and the potential impact of implementing large-scale competency-based job changes.

Research participation by members of racial or ethnic minority groups continues to be less than optimum resulting in difficulties to generalization of research findings. Community-engaged research that relies on a community health worker (CHW) model has been found effective in building trust in the community, thereby motivating people to participate in health research. The Sentinel Network study aimed at testing the feasibility of utilizing the CHW model to link community members to appropriate health research studies at each of the research sites.

The study was conducted at six Clinical and Translational Science Award institutions (

= 2371) across the country; 733 (30.9%) of the participants were from the University of Florida, 525 (22.0%) were from Washington University in St. Louis, 421 (17.8%) were from the University of California, Davis, 288 (12.1%) were from the University of Michigan, Ann Arbor, 250 (10.5%) were from Rochester, and 154 (6.5%) from Albert Einstein College of Medicine. Trained CHW research.

To examine research participants’ levels of satisfaction and perceptions and aid researchers to better engage research volunteers from all racial and ethnic populations in clinical trials. A participant satisfaction survey was developed that focused on three domains to reflect satisfaction with delivery of care, environment, and center operations. In addition, the survey contained open-ended questions to reflect overall experiences and perceptions. Two hundred and seventy-eight participants (55% African American and 29% non-Hispanic Whites) with an average age of 52 years completed the survey.

The results indicated that the majority of the participants rated their satisfaction very highly across all domains. Ninety percent stated they were very satisfied/satisfied or very strongly agreed/agreed in the three domains. Obtaining high-quality care/access to health care professionals (60%), learning more about their illness/disease (60%), and helping others (57%) were noted as important factors in choosing to participate in a trial. Regarding overall experience, majority of respondents stated that friendliness, expertise of staff, learning more about their disease, and contributing to science were important. Further, financial compensation was not a primary motivation for participation. A majority of participants stated that they would participate in future studies and would recommend a friend or a family member to participate in clinical trials.

The findings indicate that the degree of satisfaction with the research staff and with the specific trial itself are important determinants for enrolling, completing a study, and for participating in future trials.

While previous studies have described career outcomes of physician-scientist trainees after graduation, trainee perceptions of research-intensive career pathways remain unclear. This study sought to identify the perceived interests, factors, and challenges associated with academic and research careers among predoctoral MD trainees, MD trainees with research-intense (>50%) career intentions (MD-RI), and MD-PhD trainees.

A 70-question survey was administered to 16,418 trainees at 32 academic medical centers from September 2012 to December 2014. MD vs. MD-RI (>50% research intentions) vs. MD-PhD trainee responses were compared by chi-square tests. Multivariate logistic regression analyses were performed to identify variables associated with academic and research career intentions.

There were 4433 respondents (27% response rate), including 2625 MD (64%), 653 MD-RI (15%), and 856 MD-PhD (21%) trainees. MD-PhDs were most interested in pursuing academia (85.8%), followed by MD-RIs (57.3%) and MDs (31.2%) efforts to mentor the next generation of physician-scientists.Worldwide, early intervention services for young people with recent-onset psychosis have been associated with improvements in outcomes, including reductions in hospitalization, symptoms, and improvements in treatment engagement and work/school participation. States have received federal mental health block grant funding to implement team-based, multi-element, evidence-based early intervention services, now called coordinated specialty care (CSC) in the USA. New York State’s CSC program, OnTrackNY, has grown into a 23-site, statewide network, serving over 1800 individuals since its 2013 inception. A state-supported intermediary organization, OnTrackCentral, has overseen the growth of OnTrackNY. OnTrackNY has been committed to quality improvement since its inception. In 2019, OnTrackNY was awarded a regional hub within the National Institute of Mental Health-sponsored Early Psychosis Intervention Network (EPINET). The participation in the national EPINET initiative reframes and expands OnTrackNY’s quality improvement activities. The national EPINET initiative aims to develop a learning healthcare system (LHS); OnTrackNY’s participation will facilitate the development of infrastructure, including a systematic approach to facilitating stakeholder input and enhancing the data and informatics infrastructure to promote quality improvement. Additionally, this infrastructure will support practice-based research to improve care. The investment of the EPINET network to build regional and national LHSs will accelerate innovations to improve quality of care.Academic medical centers (AMCs) face challenges in conducting research among traditionally marginalized communities due to long-standing community mistrust. Evidence suggests that some AMC faculty and staff lack an understanding of the history of distrust and social determinants of health (SDH) affecting their communities. Wake Forest Clinical and Translational Science Institute Program in Community Engagement (PCE) aims to build bridges between communities and Wake Forest Baptist Health by equipping faculty, clinicians, administrators, and staff (FCAS) with a better understanding of SDH. The PCE collaborated with community partners to develop and implement community tours to improve cross-community AMC understanding and communication, enhance knowledge of SDH, and build awareness of community needs, priorities, and assets. Nine day-long tours have been conducted with 92 FCAS. Tours included routes through under-resourced neighborhoods and visits to community assets. Participant evaluations assessed program quality; 89% reported enhanced understanding of access-to-care barriers and how SDH affect health; 86% acknowledged the experience would improve future interactions with participants and patients; and 96% agreed they would recommend the tour to colleagues. This work supports the use of community tours as a strategy to improve cross-community AMC communication, build trust, and raise awareness of community needs, priorities, and assets.Twelve evidence-based profiles of roles across the translational workforce and two patients were made available through clinical and translational science (CTS) Personas, a project of the Clinical and Translational Science Awards (CTSA) Program National Center for Data to Health (CD2H). The persona profiles were designed and researched to demonstrate the key responsibilities, motivators, goals, software use, pain points, and professional development needs of those working across the spectrum of translation, from basic science to clinical research to public health. The project’s goal was to provide reliable documents that could be used to inform CTSA software development projects, educational resources, and communication initiatives. This paper presents the initiative to create personas for the translational workforce, including the methodology, engagement strategy, and lessons learned. Challenges faced and successes achieved by the project may serve as a roadmap for others searching for best practices in the creation of Persona profiles.Childhood obesity is a complex and multi-faceted problem, with contributors ranging from individual health behaviors to public policy. For clinicians who treat pediatric obesity, environmental factors that impact this condition in a child or family can be difficult to address in a clinical setting. Community-clinic partnerships are one method to address places and policies that influence a person’s weight and health; however, such partnerships are typically geared toward community-located health behavior change rather than the deeper social determinants of health (SDH), limiting effective behavioral change. Community-engaged research offers a framework for developing community-clinic partnerships to address SDH germane to obesity treatment. In this paper, we discuss the relationship between SDH and pediatric obesity treatment, use of community-clinic partnerships to address SDH in obesity treatment, and how community engagement can be a framework for creating and harnessing these partnerships. We present examples of programs begun by one pediatric obesity clinic using community-engagement principles to address obesity.In this report, we describe the implementation and short-term outcomes of a Special Populations Consultation Service within the University of California, Los Angeles (UCLA) Clinical and Translational Science Institute (CTSI). With the goal of increasing the quality and quantity of special population (SP) research, the UCLA CTSI Integrating Special Populations program designed a consultation service to support faculty and trainees conducting research involving one of three CTSI „special populations” children, older adults, and/or minority; underserved; or health disparity populations. The Special Populations Consultation Service offers three types of activities grant proposal studios, career consultations, and project reviews. UCLA CTSI faculty with appropriate content expertise serve as consultants. We evaluated this consultation model using satisfaction surveys and by quantifying funded grants and reported changes in career goals in SP research. Between 2016 and 2019, the Special Populations Consultation Service provided 59 consultations including 42 grant studios and was used by researchers at all levels from all four UCLA CTSI institutions. Recipients rated the consultations very highly. Funding success rates were 57% following K-level grant studios and 28% following R-level grant studios. Users of project and career consultations commonly attributed career accomplishments in part to their consultation experiences. The SP Consultation Service is feasible and acceptable and appears to enhance careers of investigators studying special populations.Advances in our understanding of epigenetics present new opportunities to improve children’s health through the counseling of parents about epigenetics concepts. However, it is important to first evaluate how parents respond to this type of information and determine the consequences of educating parents about epigenetics. We have taken an initial step toward this goal by assessing parental responses to an epigenetics learning module. Parents (n = 190, 126 mothers) responded to pre- and post-module survey questions. Prior to the module, parents reported that mothers’ lifestyles prior to conception were more important for children’s health than fathers’ lifestyles prior to conception (t = 4.49, df = 316.5, P less then 0.0001). However, after the module, there was no difference between ratings of the importance of mothers’ and fathers’ preconception lifestyles (t = 1.18, df = 319.8, P = NS). Furthermore, after viewing the module, parents increased their ratings of the importance of both mothers’ (t = -5.65, df = 294.8, P less then 0.0001) and father’s (t = -9.01, df = 287.2, P less then 0.0001) preconception lifestyles for child health. After viewing the module, most parents reported feelings of guilt and negativity regarding epigenetics (78 and 55%, respectively). When compared with lean parents, parents with overweight more often reported feelings of guilt (χ2 =10.27, P = 0.001). This work represents an important first step in evaluating parental responses to epigenetics concepts.There is a growing recognition that social support can potentially exert consistent or opposing effects in influencing health behaviours. The present paper presents a cross-sectional study, including 2,064 adults from Italy, Spain and Greece, who were participants in a multi-centre randomised controlled trial (C4H study), aiming to examine whether social support is correlated with adherence to a healthy Mediterranean diet and physical activity. Social support data were available for 1,572 participants. The majority of the sample reported emotional support availability (84·5 %), financial support availability (72·6 %) and having one or more close friends (78·2 %). Mediterranean diet adherence was significantly associated with emotional support (P = 0·009) and social network support (P = 0·021). No statistically significant associations were found between participant physical activity and the social support aspects studied. In conclusion, emotional and social network support may be associated with increased adherence to the Mediterranean diet. However, further research is needed to evaluate the role of social support in adherence to healthy Mediterranean diet.There is mounting evidence for the potential for the natural dietary antioxidant and anti-inflammatory amino acid l-Ergothioneine (ERGO) to prevent or mitigate chronic diseases of aging. This has led to the suggestion that it could be considered a 'longevity vitamin.’ ERGO is produced in nature only by certain fungi and a few other microbes. Mushrooms are, by far, the leading dietary source of ERGO, but it is found in small amounts throughout the food chain, most likely due to soil-borne fungi passing it on to plants. Because some common agricultural practices can disrupt beneficial fungus-plant root relationships, ERGO levels in foods grown under those conditions could be compromised. Thus, research is needed to further analyse the role agricultural practices play in the availability of ERGO in the human diet and its potential to improve our long-term health.Neonatal mortality rates in Indonesia are still at an alarming rate, with preterm birth as one of the causes. Nutritional deficiencies such as low level of vitamin D is suspected to be the risk factors of preterm birth but still a little knowledge about it. Vitamin D metabolism includes 25-hydroxyvitamin D3 (25(OH)D3) and 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), as the inactive and active form, with the help of 1α-hydroxylase (CYP27B1) enzyme. Our study aims to determine the differences of 25(OH)D3, 1,25(OH)2D3 and CYP27B1 enzyme in term and preterm birth. A cross-sectional study was performed in Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia, in January-June 2017. The blood sample was taken soon after delivery, to examine maternal 25(OH)D3 and 1,25(OH)2D3 in serum and tissue placenta, as well as placental CYP27B1 enzyme. Statistical analysis using SPPS version 20 was used to find significances. There were a total of sixty subjects in this study, with term-preterm birth group ratio 11. We found that placental 25(OH)D3 was significantly low (P = 0⋅001), and CYP27B1/25(OH)D3 ratio was high in preterm birth. Also, there were significant negative correlations found in CYP27B1 level and both placental 25(OH)D3 (r 0⋅481, P less then 0⋅001) and 1,25(OH)2D3 (r -0⋅365, P = 0⋅004) levels. Our study concludes that preterm birth showed lower placental 25(OH)D3 status, and higher CYP27B1/25(OH)D3 ratio compared to term pregnancy.The consumer food environment is changing an extensive variety of foods are now available in most markets, offering palatability, convenience and novelty. However, little is known about the availability and advertising of food items within food outlets, especially among developing countries. The present study examined these dimensions in 281 food outlets located around eighteen primary healthcare services in Belo Horizonte, Brazil, in 2013. These establishments were classified as large-chain supermarkets; specialised fruits and vegetable (F&V) markets; and local grocery stores, convenience stores or bakeries. Availability of F&V, availability of ultra-processed foods (UPF) and food advertising were compared across the food outlet categories by applying the χ2 test. Almost 60 % of the food outlets were specialised F&V markets, 21⋅4 % were large-chain supermarkets and 19⋅2 % were local grocery stores, convenience stores or bakeries. Almost 80 % contained at least eight types of fruits and vegetables, and 60 % contained UPF. Food advertisement was absent in 59⋅8 % of the food outlets, 19⋅6 % were advertising only F&V and 17⋅4 % were advertising only UPF. Higher F&V availability was noted inside specialised F&V markets and large-chain supermarkets than local grocery stores, convenience stores or bakeries. Advertising of F&V was more common within specialised F&V markets. However, large-chain supermarkets and local grocery stores, convenience stores or bakeries contained more frequent UPF food advertising isolated 38⋅3 and 35⋅2 %, respectively. Therefore, the availability and advertising of food items within food outlets around primary healthcare services are different according to the type of food outlet.The relationships between the total antioxidant capacity (TAC) of the diet and the risk of non-alcoholic fatty liver disease (NAFLD) have not previously been assessed. The aim of this study was to assess relationships between DTAC and odds of NAFLD in a case-control study. This case-control study was carried out in 158 patients with NAFLD and 357 healthy individuals aged 18-55 years. Dietary data were collected using validated 168-item quantitative food frequency questionnaires. Triacylglycerols (TAGs), total cholesterol (TC), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C) and fasting blood glucose (FBS) concentrations were assessed using enzymatic methods and commercial kits. The DTAC was calculated based on the oxygen radical absorbance capacity of each food reported by the U.S. Department of Agriculture. The mean ± sd (standard deviation) for age and body mass index (BMI) of the study participants were 43⋅9 years ±5⋅9 and had 30⋅5 kg/m2 ±2⋅6. The NAFLD patients included higher BMI and female proportion, compared with the control group. The NAFLD patients included higher smoking rates, biochemical parameters (TG, TC, LDL-C and FBS) and DTAC scores, compared with control groups (P-value less then 0⋅05). However, patients with NAFLD had lower HDL levels and physical activities, compared with the control group. The highest tertile of DTAC showed lower odds of NAFLD, compared with the lowest tertile. This association was significant after adjustment for potential confounders (OR, 0⋅19; 95 % CI, 0⋅9-0⋅34; P for trend 0⋅001). Findings suggest that the promotion of naturally increased antioxidant capacities may help prevent odds of NAFLD.

Smokeless tobacco (ST) use is one of the most important public health problems in Southeast Asia. The use of these substances increases the incidence of some cancers and other diseases. The purpose of this review study was to investigate on ST use in Iran.

A literature search was conducted on PubMed, Google Scholar, and three national databases [Scientific Information Database (SID), IranMedex, and IranDoc] based on the standard search strategy.

Most consumer people lived in Sistan and Baluchestan Province (Zahedan and Chabahar Cities) and Golestan Province, Iran. ST use rates ranged from 11.0% to 45.7% among college students in Sistan and Baluchestan (Zahedan and Chabahar) and Golestan. There are various types of ST consumed in Iran that have been mentioned in various articles, including Pan, Gutka, Nass, Naswar, Biti, and Supari.

Most studies on ST have been conducted in Sistan and Baluchestan and Golestan Provinces and we need more research for other provinces. Consumption by women is a warning and a threat to women’s health in the future. Further studies will be needed to find out more precisely the prevalence of consumption in Iran.

Environmental tobacco smoke (ETS) is one of the most toxic environmental exposures and passive smoking is an important general health problem. Children are the most vulnerable group to ETS exposure. This study aimed to compare the salivary total antioxidant capacity (TAC) and lipid peroxidation levels in passive smoking and nonsmoking adolescents aged 12-15 years.

This descriptive-analytical study was conducted on 80 adolescents aged 12-15 years. The case group included passive smokers and the control group comprised nonsmokers. These groups were age- and sex-matched ones. Unstimulated saliva of both groups was collected using the spitting method. Then, the salivary total antioxidant and lipid peroxidation levels were measured using the ferric-reducing antioxidant power (FRAP) and thiobarbituric acid reactive substances (TBARS) assays, respectively. The independent samples t-test was used for data comparison.

There was a significant difference in salivary total antioxidant levels between the case group (51.98 ± 88.97 µM) and the control group (174.35 ± 148.15 µM) (P = 0.003). There was no significant difference between the case group (0.97 ± 1.96) and the control group (0.81 ± 0.97) in lipid peroxidation levels (P = 0.542).

It seems that passive smoking can reduce the salivary TAC of adolescents, thereby threatening oral cavity health.

Smartphone usage has increasing during recent years. Since its excessive use can have negative consequences, it is important to know how users use it and become dependent on it. This study was aimed at exploring how university students use their phones, how they depend on them, and the possible consequences of overusing them.

This study was conducted using a qualitative design and with a thematic analysis method. Data were collected using 3 focus group discussions regarding experiences of using smartphones among 22 smartphone owners who reported smartphone overuse. They were chosen through snowball sampling at a University of Medical Sciences in Tehran (Iran).

Based on the analysis, the 3 categories of process usage (sub-categories doing daily routines, information seeking, to take a picture or video, entertainment, academic work, making money, to escape real-life, and passing the time), social usage (sub-categories relationship with family, relationship with friends, interact with the opposite gender, to be seen and heard, approval seeking, and free expression), and disadvantages (sub-categories interference with other essential activities, decreased face-to-face communications, overdependence, automatic use, loss of sense of time, stress, fatigue, sleep disturbances, physical inactivity, eye problems, high bills, and distraction) were developed.

In this research, participants mentioned various uses of their smartphones that enable them to meet their personal needs and, in spite of the negative consequences of its overuse, cause them to continue to use it. Some uses seem to be affected by environmental and cultural conditions.

Explaining the risk and protective factors of waterpipe tobacco smoking (WTS) is the most important principle in designing preventive interventions. This study examined the relationship between self-reported childhood abuse and WTS among health science students in Iran.

This cross-sectional study was conducted among 776 health science students in Kerman City, located in southeast of Iran, who were selected by quota sampling approach. The study was performed using two valid short instruments for measuring WTS and child abuse including physical, emotional, and sexual abuse using a self-report method.

The prevalence of ever use and current use (last 30 days) of WTS among participants was 49.6% and 33.4%, respectively. The initiation age of WTS in 60% of students was < 18 years. Child sexual abuse (CSA) was [odds ratio (OR) = 3.05, 95% confidence interval (CI) 2.06-4.52, P < 0.001] the main predictor for WTS among students.

Protecting children during childhood to prevent them from becoming victims may be an essential primordial preventive strategy for WTS.

Psychoactive substance use is a significant problem and the perception of physicians and medical students for this problem is important since it may affect their behavior regarding managing patients who suffer from substance-related problems. The objective of this study was to examine the perception of Sudanese medical students regarding psychoactive substance use and its possible associations with sociodemographic factors.

This cross-sectional study was carried out at a private Sudanese medical school in Khartoum, Sudan. A self-reporting questionnaire was distributed to all consenting students and data were analyzed using SPSS software. Chi-square test was used to analyze the associations between different factors.

Three hundred and seventeen students participated in the study, with response rate = 75.5%. Among them, 113 (35.9%) were men. The mean and standard deviation (SD) of age was 21.5 ± 4.2 years. All students knew alcohol and 261 students (88.5%) reported having knowledge about cannabis. Knowledge about cannabis, cocaine, and heroin was more prevalent among female students. Most of the students disagreed with the behavior of substance use, e.g., 94.2% in the case of alcohol. Most students reported that it would be difficult – or even impossible – for them to use psychoactive substances.

Most of the students perceived use of psychoactive substances to be associated with moderate to severe risk. Female gender and studying secondary school in Sudan were associated with perceiving more risk. Sudanese students’ perception of psychoactive substance use seems to be favorable but still increasing awareness is recommended.

This study was conducted to evaluate the impact of filter on the eventual carcinogenic and non-carcinogenic risks caused by the main toxic constituents of popular cigarette brands in Iran.

At this laboratory study, the concentration of benzene, formaldehyde, arsenic, and cadmium in the mainstream smoke of 11 popular cigarette brands in Iran, on the without and with-filter modes was determined based on an established method. The hazard quotient (HQ), incremental lifetime cancer risk (ILCR), and mixture quantitative risk assessments (QRAs) were performed based on the QRA method recommended by United States Environmental Protection Agency (USEPA).

The mean of HQ due to benzene, formaldehyde, arsenic, and cadmium in without-filter cigarette smoke was from 3.96 to 3505. The findings indicated that the HQs related to benzene, formaldehyde, arsenic, and cadmium in cigarette smoke were decreased with filter by 48.3%, 25.3%, 37.6%, and 49.1%, respectively. The filter of cigarette decreased ILCR of benzene, formanvestigate the impact of the type of fiber used in cigarette filter on reducing carcinogenic and non-carcinogenic risks caused by cigarette smoke.

Smoking tobacco is a significant health problem for humankind. Cigarettes could affect people’s life from socioeconomic and psychosomatic aspects. The oral cavity is the first orifice through which cigarette smoke enters the body. Thus, it is directly exposed to cigarettes and their harmful ingredients. This study aimed to determine the effects of smoking cessation on oral health-related quality of life (OHRQoL).

The subjects in the present observational study consisted of individuals visiting a specialized smoking cessation clinic in Tehran, Iran, to give up their smoking habit. After documentation of the subjects’ demographic data, the questionnaire [Oral Health Impact Profile (OHIP-14)] was completed twice in three months (before giving up smoking and three months after initiating the program to quit smoking). Data analysis was performed using Sig. (2-tailed), paired t-test, and one-way analysis of variance (ANOVA) at a confidence interval (CI) of 95%.

Thirty-one subjects (29 men, 2 women) participated in this study. The mean age of the subjects was 37.03 ± 11.30 years. Although OHRQoL scores were increasing as to some parameters, including food tastes, anxiety, and a feeling of shame in the subjects after giving up smoking, it was not statistically significant (P > 0.050). On the other hand, the relationship between the quality of life (QoL) (before and after stopping smoking) and age was significant (P = 0.001 before quitting and P = 0.050 after quitting).

For a better understanding of the relationship between quitting smoking and an improvement in OHRQoL, it is necessary to perform more extensive studies in this field. The present study was a pilot study, which shed some light on the relationships between these parameters.

Lead poisoning is now more common due to accidental or intentional exposure to opium impregnated with lead. We aimed to determine the relationship between the blood lead levels (BLLs) and basic characteristics in opium-poisoned children.

In this cross-sectional study, 32 children younger than 13 years old who had been admitted to Loghman Hakim Poison Center, Tehran, Iran, due to opium poisoning, were evaluated for BLLs. Patients’ demographics, symptoms, signs, and lab tests were evaluated as well as the BLLs.

The median and range of age in children with opium poisoning were 14 and 141 months with minimum and maximum age of 3 and 144 months, respectively, and 62.5% were boys. Their mean BLL was 9.78 ± 3.44 μg/dl and in 70% of opium-poisoned children, BLL was ≥ 5 μg/dl. There was a significant difference between mean BLLs in girls and boys (17.07 ± 6.57 μg/dl in girls and 6.61 ± 3.22 μg/dl in boys, P = 0.02). We found a significant correlation between BLL and hemoglobin (Hb) level. In very low Hb level (< 8 g/dl), the BLL was higher but with increasing Hb level, BLL increased as well; in Hb levels > 14 g/dl, BLL decreased again (P = 0.01).

Although none of the children needed chelation therapy, strategies should be developed to prevent children from being exposed to opium and other materials impregnated with lead regarding its effects on all organs of children.

Patients who tested positive for COVID-19 are mostly asymptomatic or present with mild self-limiting symptoms. While GI symptoms occur with less prevalence, they are increasingly being reported. A diagnosis of Covid-19 has increased dramatically in patients presenting with gastrointestinal symptoms suggesting that GI symptoms should be taken into serious consideration with patient diagnosis. Case 1 A 65-year-old man presented to the hospital emergency room with abdominal pain, Murphy’s sign and chills without fever, subsequently diagnosed as acute acalculous cholecystitis with a positive COVID-19 rRT-PCR. Case 2 A 78-year-old woman presented to the hospital emergency room complaining of severe positional epigastric pain precipitated by lying supine, chills with no fever, being later diagnosed as acute pancreatitis and a positive COVID-19 rRT-PCR. It has become evident that the ACE2 receptor plays a significant role as the entry site into human cells for the virus. This receptor is generally expressed in respiratory cells, as well as the gastrointestinal tract, corresponding with extrapulmonary manifestations of COVID-19. Studies concluded that the origin of gastrointestinal symptoms could be caused by the interaction of the SARS-CoV-2 virus with cells through the ACE2 receptor. The findings of the present study support this theory, as both patients presented with symptoms regarding tissues with high ACE2 expression.COVID-19 is a new contagious viral pneumonia with various signs and symptoms, including loss of consciousness, liver injury, and cerebrovascular accident; however, there is little data on the manifestation and outcome of COVID-19 in liver transplant patients. Moreover, because transplant units in Iran were closed from the first day of the COVID-19 pandemic, accurate data about nosocomial COVID-19 and the liver transplant setting is not available. In this article, we introduce a liver transplant recipient with a final fatal outcome, who had had neurological manifestations, and whose COVID-19 manifestations began in the hospital within 2 days of transplant surgery.Today, COVID-19 pneumonia causes global concern. The World Health Organization (WHO) has reported many mortalities from this disease all around the world. Therefore, recognizing new cases of COVID-19 is crucial during this pandemic. Many studies have shown that COVID-19 has a broad spectrum of signs and symptoms, including GI and cutaneous manifestations. Previous studies have reported liver enzyme changes as well as diarrhea as a common GI manifestation of COVID-19. However, there are few reports about COVID-19 synchronous cutaneous and liver involvement. Additionally, there are few reports about intrahepatic cholestasis in COVID-19 patients. In this article, a confirmed case of COVID-19 with vasculopathy-related cutaneous manifestation and liver cholestasis is reported. A 67-year-old Iranian woman was admitted to Taleghani Hospital with epigastric pain, vomiting, anosmia, rising liver enzyme levels, fever, itching, and skin rashes. Skin and liver biopsies were performed during the patient’s admission; the results suggested vasculopathy-related cutaneous lesion and liver cholestasis. Plasmapheresis was initiated and all manifestations disappeared after treatment. All atypical presentations, including cutaneous lesions and liver manifestations, should be considered as COVID-19 and evaluated.Diarrhea is common after liver transplant. Although the majority of episodes are experienced during the first year of transplantation, they can occur any time after the procedure. Diarrhea can impose a major risk of morbidity and mortality on transplanted patients; so a careful evaluation is required to manage it. There are few studies highlighting the gastrointestinal manifestations of COVID-19, in particular among immunosuppressed patients. The predominant respiratory symptoms of coronavirus cause GI aspects of the virus to be overlooked. This study represents a young woman with a history of liver transplant who was referred to the hospital because of diarrhea, fever, and abdominal pain attributed to coronavirus infection.

We propose the Modified Corona Score (MCorona score), an alternative approach to identifying new likely Covid-19 patients without positive chest images, but with gastrointestinal onset.

In April, 2020, a total of 104,291 laboratory-confirmed cases had been documented in Italy; Lombardy, the Northern Italian Region, recorded over 60,000 Covid-19 cases.

The MCorona score is built by several laboratory parameters linked between age and gender, ranging from 0 to 10.

Using the preliminary score cut-off of 4, we successfully identified likely Covid-19 patients with gastrointestinal onset. However, more caution is needed, and a larger sample size is required to verify the accuracy and specificity of the score.

We propose the complete validation of the MCorona score, an instrument able to diagnose likely Covid-19 patients with symptoms other than respiratory distress.

T cells and IL-6 in peripheral blood samples of hospitalized COVID-19 patients.

COVID-19 is an emerging disease with worldwide distribution. However, there is a little data about the correlation between the disease and the host immune responses.

Whole blood samples of 30 COVID-19 patients and eight healthy people were collected during March to June 2020. Total RNA was extracted from the samples, cDNA synthesis was performed, and the expression level of targeted genes was evaluated using quantitative real-time PCR.

The expression level of CD4, CD25, and Foxp3 was significantly downregulated 5-, 2-, and 3-fold, respectively, among COVID-19 patients in comparison to healthy controls (

-value < 0.0001). The expression level of IL-6 represented almost 18-fold increase in COVID-19 patients compared to healthy controls.

Our findings indicated the expression profile analysis of CD4

The present study aimed to identify human protein-host protein interactions of SARS-CoV-2 infection in the small intestine to discern the potential mechanisms and gain insights into the associated biomarkers and treatment strategies.

Deciphering the tissue and organ interactions of the SARS-CoV-2 infection can be important to discern the potential underlying mechanisms. In the present study, we investigated the human protein-host protein interactions in the small intestine.

Public databases and published works were used to collect data related to small intestine tissue and SARS-CoV-2 infection. We constructed a human protein-protein interaction (PPI) network and showed interactions of host proteins in the small intestine. Associated modules, biological processes, functional pathways, regulatory transcription factors, disease ontology categories, and possible drug candidates for therapeutic targets were identified.

Thirteen primary protein neighbors were found for the SARS-CoV-2 receptor ACE2. ACE2 and and inflammation. The results suggest that antiviral targeting of these interactions may improve the condition of COVID-19 patients.

Introducing possible diagnostic and therapeutic biomarker candidates via the identification of chief dysregulated proteins in COVID-19 patients is the aim of this study.

Molecular studies, especially proteomics, can be considered as suitable approaches for discovering the hidden aspect of the disease.

Differentially expressed proteins (DEPs) of three patients with demonstrated severe condition (S-COVID-19) were compared to healthy cases by a proteomics study. Cytoscape software and STRING database were used to construct the protein-protein interaction (PPI) network. The central DEPs were identified through topological analysis of the network. ClueGO+CluePedia were applied to find the biological processes related to the central nodes. MCODE molecular complex detection (MCODE) was used to discover protein complexes.

A total of 242 DEPs from among 256 query ones were included in the network. Centrality analysis of the network assigned 16 hub-bottlenecks, nine of which were presented in the highest-scored protein complex. Ten protein complexes were determined. APOA1 was identified as the protein complex seed, and APP, EGF, and C3 were the top hub-bottlenecks of the network. The results specify that up-regulation of C3 and down-regulation of APOA1 in urine play a role in the stiffness in respiration and, accordingly, the severity of COVID-19. Moreover, dysregulation of APP and APOA1 could both contribute to the possible adverse effects of COVID-19 on the nervous system.

The introduced central proteins of the S-COVID-19 interaction network, particularly APOA1, can be considered as diagnostic and therapeutic targets related to the coronavirus disease after being approved with complementary studies.

This research aimed to investigate neutrophil-to-lymphocyte ratio (NLR) with C-reactive protein to identify potential clinical predictors and analyze differences among severe and non-severe COVID-19 patients.

NLR and CRP are established markers that reflect systemic inflammatory, and these parameters alter in patients with novel coronavirus (SARS-CoV-2) pneumonia (COVID-19).

A population of patients with COVID-19 referred to Loghman Hospital in Tehran was analyzed. The baseline data of laboratory examinations, including NLR and CRP levels, was collected. Pearson analysis was used to assess the independent relationship between the NLR with disease severity and CRP levels.

COVID-19 cases comprised 14 (20%) patients with severe disease and 56 (80%) with non-severe infection. The mean values of WBC, NEU, LYM, and NLR of the severe patients were significantly higher than those of the non-severe patients. Forty-six patients (65.7%) had NLR >1, and the remaining patients had NLR <1. Plasma CRP levels were higher in severe cases than in non-severe cases, and this difference was significant. The results showed that NLR was positively correlated with CRP levels (R=0.23) and negatively correlated with WBC (R=-0.38). CRP (AUC = 0.97, 95% CI 0.95-0.99) and NLR (AUC = 0.87, 95% CI 0.81-0.93) had very good accuracy in predicting the severity of COVID-19 disease.

The findings of this study indicated that the integration of NLR and CRP may lead to improved predictions and is recommended as a valuable early marker to assess prognosis and evaluate the severity of clinical symptoms in COVID-19 patients.

This study demonstrated potent inhibitors against COVID-19 using the molecular docking approach of FDA approved viral antiprotease drugs.

COVID-19 has now spread throughout world. There is a serious need to find potential therapeutic agents. The 3C-like protease (Mpro/6LU7) is an attractive molecular target for rational anti-CoV drugs.

The tertiary structure of COVID-19 Mpro was obtained from a protein data bank repository, and molecular docking screening was performed by Molegro Virtual Docker, ver. 6, with a grid resolution of 0.30 Å. Docking scores (DOS) are representative of calculated ligand-receptor (protein) interaction energy; therefore, more negative scores mean better binding tendency. Another docking study was then applied on each of the selected drugs with the best ligands separately and using a more accurate RMSD algorithm.

The docking of COVID-19 major protease (6LU7) with 17 selected drugs resulted in four FDA approved viral antiprotease drugs (Temoporfin, Simeprevir, Cobicistat, Ritonavitro and in-vivo evaluations be conducted to determine the effectiveness of these drugs against COVID-19.The coronavirus disease 2019 (COVID-19) is responsible for the new pandemic, which remains an important health and economic challenge worldwide. The causative agent is a novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is similar to SARS-CoV-1 and Middle East respiratory syndrome coronavirus (MERS-CoV). Adult infection with respiratory symptoms was considered in the beginning of the pandemic. Now, it has been reported that SARS-CoV-2 infects children and other organs such as the gastrointestinal tract. SARS-CoV-2 enters the host cells through angiotensin converting enzyme-2 (ACE2) receptors as the main receptor expressed in various organs such as the lungs and gastrointestinal tract. Studies on children and the clinical manifestations of COVID-19 do not completely explain the natural course of infection in children, and precisely how the GI tract is involved is not understood. The present article highlights the gastrointestinal manifestations and pathological findings in children with COVID-19. According to the evidence, SARS-CoV-2 infection is milder in children and may present different clinical symptoms from adults. Common clinical manifestations of pediatric COVID-19 include cough, fever, sore throat, malaise, fatigue, and GI symptoms such as diarrhea, abdominal pain, nausea, and vomiting. Furthermore, liver and pancreatic enzymes may be elevated during the pediatric COVID-19 course. Asymptomatic children carriers are potential sources of infection for adults, especially elderly ones. Diagnosis, treatment, and isolation of children are the most effective ways to control the expansion of the COVID-19 pandemic.
