RESUMO

BACKGROUND: Owing to the growth of case reports and changes in the policy of journals in publishing this evidence, the need to standardize them is felt more than before. Therefore, in this study, the authors' guide of medical journals indexed in the Scopus database that published most of the case reports has been analyzed to identify the reporting requirements and emerging case report types. METHODS: A total of 50 journals were selected from the Scopus citation database (the world's largest knowledge base) that published most of the case reports. These and the authors' guideline section on the types and requirements of writing case reports were analyzed by inductive content analysis. RESULTS: Most of the case reports were published in the fields of dermatology and surgery and general medicine. Reporting requirements in author's guide are grouped in four categories: (1) reasons for publication or content value, (2) emphasis on the patient consent form and confidentiality, (3) emphasizing the constraints on the word count and limitation, and (4) recommendation for structure and reporting elements. In terms of adherence to the reporting guidelines, 76% of journals do not adhere to any reporting guideline. In addition, 13 types of case reports were identified in these journals, among which traditional case reports, clinical image, letters, and case series were the most widely used formats. CONCLUSIONS: Improving the publication processes of case reports has been left unattended by international organizations. The policies of journals need to become more integrated, and reporting guidelines should be modified or redeveloped to enhance the quality of publications, cover different reporting requirements, and consequently, benefit from the evidence value available in case reports.

RESUMO

BACKGROUND: Patient education information material (PEIM) is an essential component of patient education programs in increasing patients' ability to cope with their diseases. Therefore, it is essential to consider the criteria that will be used to prepare and evaluate these resources. OBJECTIVE: This paper aims to identify these criteria and recognize the tools or methods used to evaluate them. METHODS: National and international databases and indexing banks, including PubMed, Scopus, Web of Science, ProQuest, the Cochrane Library, Magiran, SID and ISC, were searched for this review. Original or review articles, theses, short surveys, and conference papers published between January 1990 and June 2022 were included. RESULTS: Overall, 4688 documents were retrieved, of which 298 documents met the inclusion criteria. The criteria were grouped into 24 overarching criteria. The most frequently used criteria were readability, quality, suitability, comprehensibility and understandability. CONCLUSION: This review has provided empirical evidence to identify criteria, tools, techniques or methods for developing or evaluating a PEIM. The authors suggest that developing a comprehensive tool based on these findings is critical for evaluating the overall efficiency of PEIM using effective criteria.

RESUMO

BACKGROUND: The dorsomedial periaqueductal gray (dmPAG) is a mesencephalic area and has numerous functions including cardiovascular regulation. Because nitric oxide (NO) is present in the dmPAG, here we investigate, the probable cardiovascular effect of NO in the dmPAG. METHODS: Five groups (n = 6 for each group) were used as follows: (1) control; (2) L-NAME (NG -nitro-L-arginine methyl ester, a NO synthase inhibitor, 90 nmol); (3) L-arginine (L-Arg, a precursor for NO, 60 nmol); (4) Sodium nitroprusside (SNP, a NO donor, 27 nmol); and (5) L-Arg + L-NAME. The cardiovascular parameters were recorded by a Power Lab device after cannulation of the femoral artery. Drugs were injected using a stereotaxic instrument. The changes (∆) in systolic blood pressure (SBP), mean arterial pressure (MAP), and heart rate (HR) were calculated at different times and compared to the control group. RESULTS: Microinjection of L-NAME significantly increased ∆SBP, ∆MAP, and ∆HR more than saline (from p < 0.05 to p < 0.001). L-Arg only significantly increased ∆HR (p < 0.05). In the L-Arg + L-NAME group, the above parameters also significantly increased (from p < 0.01 to p < 0.05) but not as significantly as with L-NAME alone. Microinjection of SNP significantly decreased ∆SBP and ∆MAP more than in the control and L-NAME groups (from p < 0.01 to p < 0.001), but ∆HR did not change significantly. CONCLUSION: The results indicated that NO in dmPAG has an inhibitory effect on cardiovascular responses in anesthetized rats.

RESUMO

Background: Paraquat (PQ) poisoning is a serious public health concern, especially in developing countries, due to its easy access and lack of awareness of potential harms. No effective treatment has been reported yet. Conventional hemodialysis (HD) is still used in many centers for excreting PQ or reducing acute kidney injury, but there is no consensus on its efficacy. Therefore, we aimed to review the HD efficacy in PQ poisoning mortality. Materials and Methods: We searched Web of Science, PubMed, Excerpta Medical Database, Google Scholar, Scopus, Cochrane, Web of Knowledge, Pro-Quest, ScienceDirect, Springer, Clinical Key, Scientific Information Database, Magiran, and Iran-doc, in publications before January 1, 2020. We compared patients who underwent HD (Group 1) with those who did not (Group 2). The outcome was considered mortality/survival. The data were analyzed by Comprehensive Meta-analysis Software. Results: This systematic review and meta-analysis included five studies with a combined total of 203 patients. The patients in the Group 1 had higher mortality than Group 2 (odds ratio, 2.84; 95% confidence interval: 1.22-6.64; P = 0.02). There was no evidence of publication bias (P value for Egger's test = 0.833). Conclusion: Although HD did not affect the survival of patients, other variables such as the amount of ingested PQ, poisoning severity, the time between PQ ingestion and the start of HD, duration, and times of HD sessions may influence the results regarding mortality.

RESUMO

Resistance training improves muscle strength through a combination of neural plasticity and muscle hypertrophy. This study aimed to evaluate the effects of resistance exercise on sciatic nerve regeneration and histology, growth-associated protein 43 (GAP-43) expressions, and soleus muscle atrophy following traumatic nerve injuries in Wistar rats. In the present study, 40 male Wistar rats were randomly assigned into four groups: healthy control (HC) as a sham group was exposed to the surgical procedures without any sciatic nerve compression, lesioned control (LC), resistance training (RT,non-lesioned), and lesioned rats + RT (LRT) (n = 10 in each). The RT group performed a resistance-training program 5 days/week for 4 weeks. Sciatic functional index (SFI) score, beam score and Basso, Beattie, and Bresnahan (BBB) score decreased and the hot plate time increased significantly in the LC| group compared to the HC (p < 0.05) group. However, the LRT| group showed a significant increase in the SFI score (p = 0.001) and a significant decrease in hot plate time (p = 0.0232) compared to the LC group. The LC group also showed neurological morphological damage and muscle atrophy and a decrease in GAP-43 in nerve tissue. In comparison to the LC group, a significant increase in sciatic nerve caliber, diameter, number of muscle fibers, and the expression of GAP-43| (p < 0.05) was observed in the LRT group. Doing resistance training even for four weeks seems to affect sciatic nerve lesions and injuries. It can also repair and regenerate nerve tissue by upregulating GAP-43 expression|, improving motor behavioral tests, and controlling muscle atrophy.

RESUMO

PURPOSE: To systematically review the published manuscripts on stereopsis after corneal refractive surgery. METHODS: The Web of Science, PubMed, Scopus, ProQuest, Clinical Key, Embase, and Cochrane Library were searched for relevant articles published until August 2020. The fixed- or random-effects models were used to estimate the Weighted mean difference (WMD) or Relative risk (RR) and 95% Confidence interval (CI) for postoperative stereopsis changes and incidence when applicable. Meta-regression was conducted for adjusting the effects of potential confounders. RESULTS: Seven studies (1266 eyes) in adults and ten studies in pediatrics (259 eyes) were included. In adults, stereopsis improved significantly compared to the preoperative state (WMD = - 27.4, 95% CI = - 40.0, - 14.7; I2 = 97.8%; P < 0.001). In pediatrics, proportion of patients with stereoacuity postoperatively was 2.18 times compared to preoperative evaluation. (RR = 2.18, 95% CI = 1.2, 3.9; I2 = 68.6%, P < 0.001). CONCLUSIONS: Stereopsis improves after corneal refractive surgery in adults and pediatrics.

RESUMO

This paper presents a study investigating the potential market of ridesourcing services, with a focus on the attitudinal and preferential differences between Millennials and Generation Xers. Data obtained from a stated preference survey were utilized, where the respondents were asked to choose between a conventional mode (private vehicle driver, transit, or private vehicle passenger) and ridesourcing modes (exclusive ride and shared ride). Error component nested logit models were developed for Generation Xers and Millennials, respectively. Latent attitudes derived through factor analysis were incorporated into models. A wide range of attitudinal indicators, including general mobility attitudes, perceived benefits and concerns of shared mobility services, reasons for or against owning a car, reasons for ridings Autonomous Vehicles (AV), and the most desired AV features were considered to extract latent attitudes. Model results indicated distinct mode choice behavior between Millennials and Generation Xers. For Generation Xers, the choice to switch to ridesourcing was highly dependent on the perceived time and cost benefits of shared mobility. On the other hand, Millennials' choices were more likely to be influenced by their attitudes or desire toward technology, on-demand services, and driving stress relief. Interestingly, the joy of driving showed a negative impact on Millennials' use of shared-ride services only. The findings from this study provide a more in-depth understanding of the distinct behavior of Generation Xers and Millennials toward shared mobility services, which could help develop strategies and policies to focus more effectively on the needs and concerns of individuals based on their characteristics and attitudes and help promote sustainable transportation system.

RESUMO

BACKGROUND: To evaluate the effects of intravitreal silicone oil (SO) on the retinal and choroidal thickness in eyes with rhegmatogenous retinal detachment (RRD). METHODS: A literature search was performed in Web of Science, Scopus, ProQuest, Embase, Clinical Key, Science Direct, Cochrane Library, and Springer, as well as Persian databases, including IranDoc, MagIran, SID, MOH thesis, and MOH articles until June 2020. Two reviewers independently searched and extracted the data. RESULTS: Sixteen studies (n = 391) met the inclusion criteria. The meta-analysis showed that the SO tamponade could significantly reduce the central macular thickness (CMT) in patients with RRD as compared to gas tamponade WMD = - 14.91; 95% CI: - 22.23, - 7.60; P < 0.001, I2 = 71%). No significant change was found in CMT between the eye with SO tamponade (after SO removal) and the fellow healthy eye in patients with RRD (WMD = - 3.52; 95% CI: - 17.63, 10.59; I2 = 68.6%). Compared to the preoperative stage, the SO tamponade could significantly reduce the subfoveal choroidal thickness in patients with RRD (WMD = - 18.67, 95% CI: - 30.07, - 1.28; I2 = 80.1%). However, there was no significant difference in the subfoveal choroidal thickness before and after SO removal (WMD = - 1.13, 95% CI: - 5.97, 3.71; I2 = 87.6%). CONCLUSION: The SO tamponade had a significant effect on the reduction of retinal layers and the subfoveal choroidal thickness.

RESUMO

BACKGROUND: Nowadays, providing access to the required information by clinical informationist (CI) is vital for clinical teams to make the best decision. This study was carried out to identifying how CIs should participate in grand round (GR). MATERIALS AND METHODS: The current study is an action research study. It was conducted in the GR sessions of the Gastroenterology department of Al-Zahra Hospital affiliated with Isfahan University of Medical Sciences in 2017. Participants included attending physicians, fellowship students of the Gastroenterology departments, a CI, and two supervising medical librarians. Data were collected through observation and discussion. Qualitative content analysis and concept mapping were used for data analysis. RESULTS: The findings indicated that existing problems were related to the CI, medical team, and infrastructural ones. The participation of the CI in medical team was arranged based on the following steps: planning, action, evaluation, and suggestions. It started from an initial diagnosis of patients and ended in GR meetings. During evaluation step, suggestions were made to remove the existing problems and in the fifth step, results were summarized and a framework for the participation of the CI in GR sessions was suggested. CONCLUSIONS: Medical team members were satisfied with the participation of the CI, but it is necessary to remove the existing structural and personal barriers (related to the CI and medical team members), in order to improve the efficiency of this participation.

RESUMO

Amphiphilic surfaces, containing both hydrophilic and hydrophobic domains, offer desirable performance for many applications such as marine coatings or anti-icing purposes. This work explores the effect of the concentration of amphiphilic moieties on converting a polyurethane (PU) system to a coating having fouling-release properties. A novel amphiphilic compound is synthesized and added at increasing amounts to a PU system, where the amount of the additive is the only variable in the study. The additive-modified surfaces are characterized by a variety of techniques including ATR-FTIR, XPS, contact angle measurements, and AFM. Surface characterizations indicate the presence of amphiphilic domains on the surface due to the introduction of the self-stratifying amphiphilic additive. The fouling-release properties of the surfaces are assessed with three biological assays using Ulva linza, Cellulophaga lytica, and Navicula Incerta as the test organisms. A change in the fouling-release performance is observed and plateaued once a certain amount of amphiphilicity is attained in the coating system, which we call the critical amphiphilic concentration (CAC).

RESUMO

OBJECTIVES: Access to high-quality information improves the quality of patient care, but lack of time and sufficient skills in information seeking can prevent access to information by clinicians. To solve this problem, clinical informationists can provide high-quality, filtered information for clinical team members. This study identified the core competencies that clinical informationists need to effectively fulfill their roles on clinical teams. METHODS: Participants were selected purposefully from clinicians and medical librarians. Data were collected through semi-structured interviews and analyzed using qualitative content analysis. RESULTS: The authors identified six competencies-communication, research, education and training, domain knowledge, information services, and technology-which together were used to develop a "CREDIT" model of core competencies for clinical informationists. CONCLUSIONS: The CREDIT model can be used as criteria for evaluating the performance of clinical informationists as well as for developing and assessing clinical informationist educational programs and curriculums.

RESUMO

BACKGROUND: Creatine (CR) and sodium bicarbonate (SB) alone improve anaerobic performance. However, the ergogenic effects of CR and SB co-ingestion on taekwondo anaerobic performance remains unknown. METHODS: Forty trained taekwondo athletes (21 ± 1 y.; 180.5 ± 7.3 cm; 72.7 ± 8.6 kg) were randomized to: (i) CR and SB (CR + SB; 20 g of CR+ 0.5 g·kg- 1·d- 1 of SB), (ii) CR, (iii) SB, (iv) placebo (PLA), or (v) control (CON) for 5 days. Before and after supplementation, participants completed 3 bouts of a Taekwondo Anaerobic Intermittent Kick Test (TAIKT) to determine changes in peak power (PP), mean power (MP), and fatigue index (FI). Blood lactate (BL) was measured before, immediately following, and 3 min post-TAIKT. RESULTS: PP and MP increased over time (P < 0.05) following CR + SB, CR, and SB ingestion, with no changes in the PLA or CON groups. There was a greater increase over time in MP following CR + SB (Absolute Δ: 1.15 ± 0.28 W∙kg67) compared to CR (Absolute Δ: 0.43 ± 0.33 W∙kg67; P < 0.001) and SB (Absolute Δ: 0.73 ± 0.24 W∙kg67; P = 0.03). There were no significant time and condition effect for FI (P > 0.05). BL increased following exercise across all groups; however, CR + SB and SB post-exercise BL was lower compared to CR, PLA, and CON (P < 0.05). CONCLUSION: Short-term CR and SB alone enhance TAIKT performance in trained taekwondo athletes. Co-ingestion of CR and SB augments MP compared to CR and SB alone, with similar PP improvements.

RESUMO

The feasibility study of utilizing sunflower oil as renewable biomass source to develop highly effective inhibitors for mild steel corrosion (MS) in the 15% HCl medium was done by weight loss, potentiodynamic polarization (PDP), dynamic electrochemical impedance spectroscopy (DEIS), and electrochemical impedance spectroscopy (EIS), supported with energy-dispersive X-ray (EDX), atomic force microscopy (AFM), and field-emission scanning electron microscope (FESEM) techniques. Moreover, a complementary theoretical investigation was carried out to clarify the inhibition mechanism of inhibitors by density functional theory (DFT), density functional based tight-binding (DFTB), and molecular dynamics (MD) simulation approaches. The obtained results confirm that sunflower-oil-based corrosion inhibitor (SFOCI) has a significant anticorrosion property toward the dissolution of MS in 15% HCl solution in the temperature range 20-80 °C. In addition, the results show that SFOCI could provide an inhibition efficiency of 98 and 93% at 60 and 80 °C, respectively. The inhibition mechanism of SFOCIs was mixed-type and their adsorption on the surface of MS was mainly chemisorption. The FESEM and EDX studies proved the presence of SFOCI molecules on the surface of MS. In addition, the adsorption energy of SFOCI indicated an intense interaction between the inhibitor and surface of Fe. The results of this study could open a new window for the design and development of scalable and effective eco-friendly vegetable-oil-based corrosion inhibitors for highly corrosive solutions at high temperatures.

RESUMO

BACKGROUND: Cardiovascular diseases (CVDs) are in charge of many deaths worldwide including myocardial infarction (MI), hypertension (HTN), coronary atherosclerosis (CAS), infective endocarditis (IE), heart failure (HF), arterial fibrillation (AF), and peripheral artery disease (PAD). Besides, periodontitis is the sixth prevalent disease among humans and it seems that there are common risk factors between these diseases which are creating communication between prevalence and treatment. The purpose of this study is to assess the articles that reviewed the relationship between heart diseases and periodontitis. METHODS: Three databases, including PubMed, Scopus, and Web of Science were searched until November 2020. The search terms "periodontal disease, periodontitis, oral health, cardiovascular disease, atherosclerosis, myocardial infarction, hypertension, coronary heart disease, angina pectoris, arterial fibrillation, arrhythmia, and peripheral artery disease" were used in combination to identify the publications providing data. RESULTS: MI, HTN, atherosclerosis diseases for coronary artery, IE, HF, AF, and PAD were associated with periodontitis. It seems that the treatment of periodontitis may help to improve the state of mentioned heart-related diseases. However, more studies are needed to prove this relationship. CONCLUSION: The prevalence of heart diseases is more common in individuals with periodontitis.

RESUMO

Poisoning with any of the colchicine or chloroquine drugs is rare. These drugs exert therapeutic and toxic effects on tissues by different mechanisms. Colchicine is used to treat a number of rheumatologic diseases and heart problems. In addition, chloroquine is used to treat malaria and some inflammatory diseases. There is a small gap between the therapeutic and toxic doses of these drugs. Gastrointestinal symptoms are the initial causes of poisoning with these drugs and then widespread organ failure in later stages can lead to sudden cardiac death. We introduce a case of concurrent poisoning with both drugs, in which the patient presented with a headache, nausea, and vomiting several hours after suicide. On the 1st day, the patient's status was stable, but on the 2nd day, the patient suddenly becomes ill and died even though the patient received supportive therapy. Concurrent poisoning with chloroquine and colchicine is extremely lethal, and early aggressive management is recommended even in an apparently stable patient.

RESUMO

Suicide with cyanides is relatively rare but highly lethal. The lethal oral dose of cyanide salts is 200 mg, and concentrations >3 mg/L may be potentially lethal. The symptoms of poisoning are predominating in the central nervous system and cardiovascular system. We report the case of a 43-year-old goldsmith man who presented with self-poisoning by cyanide salt ingestion. Patient's symptoms included confusion, cardiac arrhythmias, hyperkalemia, leukocytosis, metabolic acidosis with high anion gap, hypotension, and then hypertension. The cause of the patients poisoning was not initially diagnosed. Intensive supportive treatment was performed. The patient died on the 3rd day of admission following cardiac arrest. At autopsy, hemorrhagic gastritis and cherry-red discoloration of the chest muscles were observed. Forensic toxicology showed cyanide in the blood and tissues. Cyanide poisoning could appear in different forms, and like our case, the symptoms can last for several days with nonspecific symptoms.

RESUMO

Clinical informationist (CI) is one of the current trends in the field of medical librarianship and information science. CIs are members of clinical care teams, and their main duty is to fill the gap in the information needs of health-care workers and patients using information sources. They need an official and standard education. This study aims to identify the educational goals and needs of CIs. To this end, a scoping review was conducted using the Preferred Reporting Item for Systematic Reviews and Meta-analyses guidelines. The ISI Web of Science, Scopus, Proquest (MEDLINE), Science Direct, Emerald, ERIC, Cochrane, and Library, Information Science and Technology Abstracts were searched. The Journal of the European Association for Health Information and Libraries was hand searched for relevant studies. A total of 1026 studies were extracted, and 38 studies were selected for the final review. The review resulted in identifying 18 goals in cognitive, emotional, and psychomotor areas. Furthermore, the educational needs were identified in eight educational needs including research method and statistics, education, medical knowledge, information and librarianship science, clinical environment knowledge, evidence-based knowledge, information technologies and systems, management, and leadership. Although part of these educational needs can be met through general medical librarianship and information science education, further specialized education for CIs requires specific aims and curriculum. Thus, the results of this study can be the basis for future studies regarding the competencies of CI in order to provide a more precise and detailed curriculum based on these educational needs.

RESUMO

BACKGROUND: To examine the effects of varying doses of caffeine on autonomic reactivation following anaerobic exercise. METHODS: Recreationally active males (N = 20; 24 ± 2y) participated in a randomized, double-blind, placebo-controlled, crossover study where participants ingested: [1] Control (CON; no supplement), [2] a non-caffeinated placebo (PLA), [3] 3-mg∙kg- 1 of caffeine (CAF3) or [4] 6-mg∙kg- 1 of caffeine (CAF6) prior to Wingate testing. Parasympathetic (lnRMSSD, primary outcome) and global HRV (lnSDNN, secondary outcome) were assessed at rest (i.e., pre-ingestion), 45-min post-ingestion, and 5-min and 35-min post-exercise recovery. We used a GLM to assess mean (95% CI) changes from pre-ingestion baseline. RESULTS: Overall, we observed a significant trend for lnRMSSD and lnSDNN (both, p = 0.001, ηp2 = 0.745). Forty-five minutes after treatment ingestion, we observed a significant increase in lnRMSSD for CAF3 (0.15 ms, 95%CI, 0.07,0.24) and CAF6 (0.16 ms, 95%CI, 0.06,0.25), both being significant (both, p <  0.004) vs. CON (- 0.02 ms, 95%CI, - 0.09,0.04). Five-minutes after exercise, all treatments demonstrated significant declines in lnRMSSD vs. baseline (all, p <  0.001). After 35-min of recovery, lnRMSSD returned to a level not significantly different than baseline for CAF3 (0.03 ms, 95%CI, - 0.05, 0.12) and CAF6 (- 0.03 ms, 95%CI, - 0.17, 0.10), while PLA (- 0.16 ms, 95%CI, - 0.25, - 0.06) and CON (- 0.17 ms, 95%CI, - 0.28, - 0.07) treatments remained significantly depressed. A similar pattern was also observed for SDNN. CONCLUSION: Caffeine ingestion increases resting cardiac autonomic modulation and accelerates post-exercise autonomic recovery after a bout of anaerobic exercise in recreationally active young men. However, no differences between caffeine doses on cardiac autonomic reactivity were observed.

RESUMO

INTRODUCTION: Due to time constraints and a significant increase in medical information, one of the ways to keep physicians and medical teams up to date is to use evidence-based medicine. The current research focused on the effects of the educational role of clinical informationist (CI) on improving clinical education among medical students based on the Kirkpatrick (KP) model. METHODS: The method was semiexperimental research in two group designed with pretest and posttest. The research population included thirty medical students for each group that was selected by the convenience time-based sequential sampling method. The study data were collected using a researcher-made two questionnaires and a checklist. Data were analyzed by the descriptive statistics and inferential statistics using SPSS version 20 software. RESULTS: Based on the first level of the KP model, the total mean of medical students' satisfaction in the experimental group was 4.06 from 5. Based on the second, third, and fourth levels of the model, the independent t-test showed that before the intervention, the mean scores of attitude, knowledge, information-seeking skills and behaviors, and also clinical skills were not significantly different in both the intervention and control groups (P > 0.05). After the intervention, the results of covariance test showed that attitude, knowledge, information-seeking skills and behaviors, and also clinical skills of the intervention group are significantly better than that of the control group (P < 0.001). CONCLUSION: Training and the presence of the CIs in the clinical round had resulted in the improved satisfaction, attitude, knowledge, and information-seeking skills while also improving information-seeking behaviors and clinical skills of medical students.
