The relationship between mobile phone addiction and depression, anxiety, and sleep quality in medical students.

This study investigates the prevalence of mobile phone addiction among medical students and its relationship with depression, anxiety, and sleep quality. The study was conducted at Mashhad University of Medical Sciences from 2019 to 2021, and it included medical students at four different levels of training. Participants were selected using a stratified random sampling method. All subjects completed the Mobile Phone Addiction Scale, Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory, and Beck Anxiety Inventory through online electronic self-report questionnaires. Overall, 355 medical students were included in the study, with 203 (57.2%) being female. Mild and severe mobile phone addiction was reported by 83.7 and 2.5% of the students, respectively. Furthermore, the study's findings revealed significantly higher sleep quality disorder, depression, and anxiety scores among students with severe mobile phone addiction compared to other participants ( P  < 0.001, P  = 0.007, and P  < 0.001, respectively). Although mobile phone addiction was prevalent, severe addiction was rare among medical students. Nevertheless, severe addiction was associated with an increased prevalence of mental health problems and sleep disturbances, emphasizing the importance of interventions aimed at reducing mobile phone addiction and improving mental health.

Patient satisfaction with e-oral health care in rural and remote settings: a systematic review.

BACKGROUND: During the past decade e-oral health technology has been used to address the oral health care challenges in rural and remote settings. This review systematically evaluated the literature on patient satisfaction with e-oral health care in rural and remote communities. METHODS: The systematic review included interventional and observational studies published between 1946 and 2021, in the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Global Health. Patient satisfaction with received oral health care using self-reported measures, at any time after the intervention, was the main outcome of the review. The other primary outcomes were undesirable consequences of the health care (e-health or conventional) such as diagnostic error. The secondary outcomes considered were waiting time, number of visits, travel, and the cost of oral health care. Two independent researchers assessed the risk of bias using the ROBINS-I risk of bias assessment tool for non-randomized studies. RESULTS: Among 898 studies, 16 studies were included in the review. In most studies reporting patient satisfaction, all patients had shown willingness for teleconsultation for a dental problem and they were mostly satisfied due to saved travel time, saved working days, and prompt treatment onset. Most of the studies acknowledged teledentistry as a cost-effective and cost-saving method. Moreover, the teledentistry consultations showed diagnostic reliability and validity values comparable to conventional dental consultations. The majority of studies were considered level 4 and 3b, due to limited sample populations, analysis based on limited alternatives or costs, non-consistent sensitivity analysis, failure to appropriately control known confounders, and/or failure to carry out an appropriate follow-up of patients. CONCLUSION: Available evidence indicates that e-oral health is associated with higher patient satisfaction and has been found to be an effective and reliable method for patients in rural and remote areas. Therefore, in these areas, the use of e-oral health should be encouraged. However, methodological inconsistencies in the current evidence suggest the need for long-term cohort studies and clinical trials, as well as cost analysis on e-oral health in rural settings. SYSTEMATIC REVIEW REGISTRATION: The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42016039942.

Osseointegration Pharmacology: A Systematic Mapping Using Artificial Intelligence.

Clinical performance of osseointegrated implants could be compromised by the medications taken by patients. The effect of a specific medication on osseointegration can be easily investigated using traditional systematic reviews. However, assessment of all known medications requires the use of evidence mapping methods. These methods allow assessment of complex questions, but they are very resource intensive when done manually. The objective of this study was to develop a machine learning algorithm to automatically map the literature assessing the effect of medications on osseointegration. Datasets of articles classified manually were used to train a machine-learning algorithm based on Support Vector Machines. The algorithm was then validated and used to screen 599,604 articles identified with an extremely sensitive search strategy. The algorithm included 281 relevant articles that described the effect of 31 different drugs on osseointegration. This approach achieved an accuracy of 95%, and compared to manual screening, it reduced the workload by 93%. The systematic mapping revealed that the treatment outcomes of osseointegrated medical devices could be influenced by drugs affecting homeostasis, inflammation, cell proliferation and bone remodeling. The effect of all known medications on the performance of osseointegrated medical devices can be assessed using evidence mappings executed with highly accurate machine learning algorithms.

Effectiveness of Topical Sucralfate in the Management of Pressure Ulcer in Hospitalized Patients: A Prospective, Randomized, Placebo-Controlled Trial.

BACKGROUND: The aim of this study was to evaluate the effectiveness of topical sucralfate in the management of pressure ulcer (PU) in hospitalized patients. METHODS: Forty hospitalized patients with stage II PU were included in this prospective, double-blind, randomized, placebo-controlled trial and were randomly divided into 2 groups receiving either sucralfate gel or placebo, on a daily basis. The patients were visited every day for 14 days, the ulcer was evaluated using the Pressure Ulcer Scale for Healing (PUSH) and changes to the measured scores over time were used as an indicator of wound healing. RESULTS: There were no statistically significant differences in any of the demographic characteristics between both groups. Both of the interventions reduced the average PUSH score, and at the end of the trial, all but 2 patients were healed. One in each group discontinued the trial because of exacerbation of the ulcer. No significant between-group difference in the average PUSH score reduction was observed (6.36 ± 2.11 vs. 5.89 ± 1.41, P = 0.42). Although the average healing time was less in the sucralfate group (6.05 ± 2.17 vs. 7.78 ± 3.42), the difference was not statistically significant (P = 0.07). CONCLUSIONS: Sucralfate gel does not improve healing of PU compared with placebo.

Topical pentoxifylline for pressure ulcer treatment: a randomised, double-blind, placebo-controlled clinical trial.

OBJECTIVE: To evaluate the effectiveness of topical pentoxifylline (PTX) on pressure ulcer (PU) healing in critically ill patients. METHOD: In this randomised, double blind, placebo-controlled clinical trial, patients with category I or II PUs were randomly assigned to receive either topical PTX 5% or a placebo twice daily for 14 days. Changes in PU characteristics (category and size) were assessed. The category of the PU was determined by the Stirling Pressure Ulcer Severity Scale (two-digit) at baseline (day zero), day seven and day 14 of treatment. PU length and width was measured with a disposable ruler and expressed as cm2. RESULTS: A total of 112 adult patients were enrolled in the study. Median PU size and score at day zero were 32 (10.00-69.33)cm2 and 1(1.00-2.00) respectively. In the PTX group, the mean differences (95% confidence interval, CI) of all PU scores and sizes decreased significantly across the intervals (day seven versus day zero, day 14 versus day zero, and day 14 versus day seven), compared with the placebo group Conclusion: The severity and size of PUs improved significantly in patients who received topical PTX 5% ointment twice a day for 14 days compared with those in the placebo group. Topical PTX may be considered as a potential option in the treatment of categories I and II PUs in critically ill patients.

Effect of Valerian in Preventing Neuropsychiatric Adverse Effects of Efavirenz in HIV-Positive Patients: A Pilot Randomized, Placebo-Controlled Clinical Trial.

BACKGROUND: Several neuropsychiatric adverse effects of efavirenz are known. Preventing these adverse effects may improve patients' adherence to antiretroviral therapy (ART). OBJECTIVES: To evaluate the efficacy and safety of valerian in preventing neuropsychiatric adverse effects of efavirenz in HIV-positive patients. METHOD: In this pilot randomized, double-blinded, placebo-controlled, clinical trial, 51 HIV-positive patients who were receiving efavirenz were recruited into the valerian (n = 25) or placebo (n = 26) group. Patients received valerian (530 mg) or placebo nightly 1 hour before sleep for 4 weeks. The neuropsychiatric status (sleep, anxiety, depression, suicidal thought, and psychosis) of patients was assessed at baseline and week 4 using validated questionnaires. RESULTS: Sleep ( P ≤ 0.001) and anxiety ( P = 0.001) significantly improved in the valerian group compared with the placebo group. Dizziness was the most common complaint of patients in first days of the intervention. In the valerian and placebo groups, 92% and 84.6% of patients experienced dizziness, respectively ( P = 0.35). Nausea was the second common adverse effect that 84% and 76.9% of patients in the valerian and placebo groups experienced ( P = 0.39). CONCLUSION: In the first 4 weeks of ART including efavirenz, valerian significantly improved sleep and anxiety in HIV-positive patients. Valerian may be considered as a potential option in preventing neuropsychiatric adverse effects of efavirenz in HIV-positive patients.

Failure rate of single-unit restorations on posterior vital teeth: A systematic review.

STATEMENT OF PROBLEM: No knowledge synthesis exists concerning when to use a direct restoration versus a complete-coverage indirect restoration in posterior vital teeth. PURPOSE: The purpose of this systematic review was to identify the failure rate of conventional single-unit tooth-supported restorations in posterior permanent vital teeth as a function of remaining tooth structure. MATERIAL AND METHODS: Four databases were searched electronically, and 8 selected journals were searched manually up to February 2015. Clinical studies of tooth-supported single-unit restorative treatments with a mean follow-up period of at least 3 years were selected. The outcome measured was the restorations' clinical or radiological failure. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, the Cochrane Collaboration procedures for randomized control trials, the Strengthening the Reporting of Observational Studies in Epidemiology criteria for observational studies, 2 reviewers independently applied eligibility criteria, extracted data, and assessed the quality of the evidence of the included studies using the American Association of Critical Care Nurses' system. The weighted-mean group 5-year failure rates of the restorations were reported according to the type of treatment and remaining tooth structure. A metaregression model was used to assess the correlation between the number of remaining tooth walls and the weighted-mean 5-year failure rates. RESULTS: Five randomized controlled trials and 9 observational studies were included and their quality ranged from low to moderate. These studies included a total of 358 crowns, 4804 composite resins, and 303582 amalgams. Data obtained from the randomized controlled trials showed that, regardless of the amount of remaining tooth structure, amalgams presented better outcomes than composite resins. Furthermore, in teeth with fewer than 2 remaining walls, high-quality observational studies demonstrated that crowns were better than amalgams. A clear inverse correlation was found between the amount of remaining tooth structure and restoration failure. CONCLUSIONS: Insufficient high-quality data are available to support one restorative treatment or material over another for the restoration of vital posterior teeth. However, the current evidence suggests that the failure rates of treatments may depend on the amount of remaining tooth structure and types of treatment.

Potential benefits of pentoxifylline on wound healing.

In this review, potential benefits of pentoxifylline (PTX) on wound healing have been evaluated. All available experimental and clinical studies examined effects of PTX on wound healing have been included. No time limitation was considered and all studies up to writing the manuscript were included. Administration of oral or parenteral PTX showed beneficial effects on the healing of colorectal anastomosis, post burn scar, radiation-induced skin/soft tissue injury, venous ulcers, recurrent aphthous stomatitis and cutaneous/mucocutaneous leishmaniasis. Data regarding effect of PTX on skin flap survival are conflicting. Only few evidences support promising effects of PTX in pressure ulcer, skin developing injury and burn.

Cyproheptadine for the Prevention of Postoperative Delirium: A Pilot Study.

BACKGROUND: Postoperative delirium is a common neurobehavioral complication after major surgeries. There is no conclusive approach for prevention of delirium in these patients. OBJECTIVE: In this study, efficacy of cyproheptadine for prevention of postoperative delirium was evaluated. METHODS: Delirium status of surgical patients was evaluated postoperatively at the time of admission to the intensive care unit (ICU) using the Confusion Assessment Method (CAM-ICU) scale. Patients without delirium were assigned to the cyproheptadine or placebo group based on the simple randomization method. Patients received cyproheptadine or placebo tablet at a dose of 4 mg 3 times per day for 7 days. Patients were monitored daily for incidence of delirium. RESULTS: Changes in the incidence rates of delirium over time during the study phase (P = 0.04) and between the groups showed statistically significant differences (P = 0.029). However, severity of delirium was not significantly different between the cyproheptadine and placebo groups during the study period. CONCLUSION: It seems that cyproheptadine with its diverse effects can be a potential option for prevention of postoperative delirium. In this pilot study, cyproheptadine significantly decreased the incidence but not severity of postoperative delirium.

Focusing on outcomes and methods in removable prosthodontics trials: a systematic review.

OBJECTIVES: The aim of this study was to systematically examine the outcomes of interest of trials in removable prosthodontics and to assess their overall quality. MATERIAL AND METHODS: Electronic databases were searched up to August 2011 and complemented by hand searching for published randomized controlled trials (RCTs) in the field of removable prosthodontics in the six major prosthodontic and implant journals. The primary outcome of RCTs was considered as the outcome of interest of this review, and only manuscripts in which the study's primary outcome was reported in the abstract were included. Outcomes were classified according to the Strength of Recommendation Taxonomy (SORT) classification. The quality of individual reports of RCTs was assessed following the Cochrane Handbook for Systematic Reviews of Interventions (Higgins & Green, www.cochrane-handbook.org). RESULTS: The search retrieved 86 reports of RCTs. Among these publications, 43% reported a patient-oriented primary outcome. Most of the publications did not present a clear description of sequence generation (54%) or allocation concealment (65%). Blinding of participants, clinicians, and outcomes assessors was not applicable or reported in most trials. Handling of withdrawals and losses was adequate in 52% of trials. CONCLUSIONS: Although published RCTs in removable prosthodontics have increased over time, efforts should be made to increase patient-reported outcomes and the methodological quality of these reports. Such improvement will lead to a better body of evidence in the field, thus providing increased support for clinical decision-making.
