Review
Visual illusions have long been used as tools to investigate sensory-perceptual deficits in schizophrenia. Recent conflicting accounts have called into question the assumption of abnormal illusion perception in patients and, therefore, the validity of this approach. Here, we present a systematic review of the current evidence regarding visual illusion perception abnormalities in patients with schizophrenia. Relevant publications were identified by a systematic search of PubMed, Literatura LILACS, PsycINFO, Embase, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), IBECS, BIOSIS, and Web of Science. Forty-five studies were selected which included illusions classified as 'Motion illusions', 'Geometric-optical illusions', 'Illusory contours', 'Depth inversion illusion', and 'Non-specific'. There is concordant evidence of abnormal processing of illusions in patients for most categories, especially in facial Depth Inversion and Müller-Lyer illusions. There were significant methodological disparities and shortcomings, but risk of bias was overall low for individual studies. The usefulness of visual illusions as tools in clinical settings as well as in basic research may be contingent on significant methodological refinements.

BACKGROUND
Despite emerging evidence on the effectiveness of eHealth interventions in improving cardiovascular health, little is known about the perception of use and efficacy of these interventions and real-world application.
OBJECTIVE
We sought to develop an in-depth understanding of the perceptions of eHealth interventions in improving cardiovascular health.
METHODS
This is a systematic review and meta-synthesis of qualitative studies. A comprehensive search of multiple databases and a manual search of the references list were conducted. Meta-synthesis of qualitative data was performed to review and interpret the findings. The study report followed the ENTREQ checklist.
RESULTS
Four themes emerged regarding perceptions of eHealth interventions: preferred eHealth intervention design features, enabling healthcare professionals' support, eHealth engagement for health benefits, and barriers to eHealth engagement. Intervention design features should integrate motivational elements, use an eHealth literacy lens, and enhance cultural relevance. Healthcare professionals appreciated these new working methods but voiced concern about competency building. Real-world usage initiation was driven by perceived needs and usefulness, whereas persistent engagement was inspired by intrinsic motivation in participants.
CONCLUSIONS
eHealth interventions were appreciated as a valuable opportunity for providing alternative/supplementary cardiac care for health optimization. Participants commented on the need for more explicit and accurate health information presentation, and they appreciated the motivational elements in empowering them with self-determination over daily self-care behaviors. Professionals raised the need for specific guidance to enhance competency and intervention fidelity when delivering eHealth care.

Review
OBJECTIVE
This systematic review aimed to summarise and update existing knowledge about ageism among nursing students through the following research question: what is the perception and attitudes of ageism among student nurses?
DESIGN
A systematic review of longitudinal and cross-sectional studies of ageism in nursing students was carried out.
DATA SOURCES
The literature search was conducted in the scientific databases Pubmed and Scopus in February 2021.
REVIEW METHODS
After the screening process, 22 studies meeting the selection criteria were selected; 8 more were identified after manually searching the selected paper' reference lists. A total of 30 studies were included in the review. The JBI Critical Appraisal Checklists for Analytical Cross-Sectional studies and for Cohort Studies were used to appraise the articles' quality.
RESULTS
There was large variability in the manifestation of ageism among student nurses, as well as in the instruments used for assessment. Most of the articles analysed attitudes towards old age, the majority of which were positive. Being a female student, being on the final year of study and having regular contact or cohabitation with an older adult were three of the main determinants in the expression of positive attitudes towards the elderly.
CONCLUSIONS
Our findings suggest that student nurses generally have positive attitudes towards old age, although ageist beliefs and discriminatory behaviours were identified and should be studied in greater depth. Training programs for future care professionals have a responsibility to educate from a non-stereotypical perspective based on current societal needs.

Review
BACKGROUND AND AIMS
In the last decades, the three-dimensional (3D) imaging systems have been introduced in an attempt to improve depth perception and image quality during laparoscopic cholecystectomy interventions. The goal of our systematic review was to provide enough convincing evidences on superiority and benefits of 3D over two-dimensional (2D) imaging systems, from both surgeon's and patient's point of view, justifying the cost-effectiveness of newly developed 3D systems.
METHODS
Two authors separately performed a full literature search aiming to find randomized controlled trials evaluating the advantages and disadvantages of 3D versus 2D laparoscopic cholecystectomy procedures. The patients who underwent elective laparoscopic cholecystectomy were included in this study irrespective of their age and sex. Differing opinions between the two authors were reviewed by the third author.
RESULTS
A total of 912 articles were initially reviewed by their titles and abstracts for eligibility. After being filtered through predetermined inclusion and exclusion criteria, and excluding the duplicates, only 10 studies underwent the final evaluation by the full text assessment. Eventually, only five randomized controlled studies were included in this study. Operative time and depth perception/image quality were set as the primary and secondary outcomes, respectively. The operative time was significantly shorter in 60% of the studies. Of five studies that evaluated the depth perception and image quality, all five (100%) reported a better depth perception and image quality.
CONCLUSIONS
3D imaging systems tend to shorten the operative time compared to 2D systems and result in a better depth perception. More studies and investigations with bigger cohort sizes and using unique 3D visual systems are necessary to justify the cost-effectiveness of the new, more expensive 3D systems.

Review
INTRODUCTION
The present systematic review was conducted to examine self-esteem and related factors in burns patients.
METHODS
A comprehensive search was conducted from the first to the April 1, 2022 at the international electronic databases such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as "Burns", "Self-confidence", "Self-perception", "Self-esteem", and "Self-concept".
RESULTS
A total of 762 burn patients were included in this review from ten cross-sectional studies. The mean score of self-esteem in burn patients based on Rosenberg Self-Esteem Scale, State Self-Esteem Scale, Cooper Smith's self-esteem questionnaire, and Rifai's self-esteem scale were 17.77 (SD = 5.55) out of 30, 65.91 (SD = 5.49) out of 100, 56.68 (SD = 5.49) out of 100, and 109.77 (SD = 9.55) out of 145, respectively. Factors associated with self-esteem in burns patients were gender, occupation, the location of the burn, type of burn, site of burn, burn scar, and quality of life had a significant relationship with burn patients' self-esteem. Factors such as social support, family support, friends support, and supporting others, had a significant positive relationship with self-esteem of burns patient. However, self-esteem in patients with burn had a significant negative relationship with grade of burn injury, percentage of burn, depth of burn, facial burn, post-traumatic stress disorder, psychiatric morbidity, major depressive, and suicidality factors.
CONCLUSION
Overall, patients with burns had moderate levels of self-esteem. Therefore, it is recommended that health professionals use interdisciplinary approaches to better manage burn patients.

Meta-Analysis Review
We estimated the proportion of children with stereopsis following surgery in congenital and developmental cataracts by systematic review and meta-analysis and also considered the factors influencing stereopsis, such as intervention age and presence of strabismus. Stereopsis is directly related to quality of life, and investigating its levels following cataract surgery in children may help decide the right time to intervene, particularly in the context of brain plasticity. We conducted a systematic literature search using Scopus, PubMed, and Web of Science and found 25 case series, 3 cohorts, and 3 clinical trial studies from 1/1/1995 to 31/12/2020. Study-specific proportions of stereopsis from 923 children were pooled using a random-effects model, and stratified analyses were conducted based on intervention age and pre-existing strabismus as a confounder. We appraised the risk of bias using tools published by National Institutes of Health and evaluated publication bias with funnel plots and the Egger test. The pooled proportions of stereopsis based on 8 unilateral and 6 bilateral congenital cataract studies were 0.37 (95% CIs: [0.24, 0.53]) and 0.45 (95% CIs: [0.24,0.68]) when patients with preexisting strabismus were excluded as a confounder. When the intervention age was ≤6 months, proportions in unilateral congenital cataract group significantly increased to 0.52 (95% CIs: [0.37, 0.66]; P = 0.49) compared to 0.26 (95% CIs: [0.14, 0.44]; P = 0.16) otherwise. A similar increase in proportions was found when intervention age ≤4 months. In both unilateral and bilateral congenital cataract groups, proportions increased significantly when the confounder was excluded. Overall, proportions in bilateral congenital cataracts were significantly greater than unilateral cases (irrespective of confounder). Eight unilateral and 5 bilateral developmental cataract studies resulted in pooled proportions of 0.62 (95% CIs: [0.27, 0.88] and 0.82 (95% CIs: [0.4, 0.97]), respectively. Although proportions for bilateral developmental cataracts were greater than unilateral cataracts (irrespective of confounder), results were not statistically significant. Finally, proportions in unilateral developmental cataracts were significantly greater than unilateral congenital cataracts (Z = 7.413, P = 6.173694e-14). We conclude that surgical intervention within first 4-6 months can significantly affect postoperative outcomes in unilateral congenital cataracts. Analysis of existing data does not show a significant effect of intervention age on stereopsis outcomes for developmental cataracts.

Review
INTRODUCTION
Postoperative delirium (POD) is defined as an acute neurologic insult characterized by changes in consciousness and cognition, altered perception and a fluctuating course. It leads to poor outcome and increased health care system costs. Considering its high incidence, up to 60%, and the lack of a first-choice treatment, prevention has become a priority. Our aim was to systematically review literature on POD prevention and to identify the role of anesthesia in this context.
EVIDENCE ACQUISITION
MEDLINE and EMBASE were searched for studies considering any anesthetic intervention intended to prevent POD. Risk of bias was assessed with the Quality Assessment Tool for Quantitative Studies for original articles and with the R-AMSTAR checklist for systematic reviews.
EVIDENCE SYNTHESIS
A total of 27 studies were included. Interventions included pre-, intra-/peri- and postoperative strategies to prevent POD. Only 9 out of 27 studies had high methodological quality. Use of a depth of anesthesia monitor and lighter sedation had the strongest evidence in reduction of POD. Perioperative dexmedetomidine, ketamine, dexamethasone, and antipsychotic administration may reduce the risk of POD.
CONCLUSIONS
Methodologically robust studies supporting strategies for preventing POD are still lacking. Based on our analysis, anesthesiologists should consider the intraoperative use of a depth of anesthesia monitor and the choice for a lighter sedation when possible. The administration of preventive medications should be considered very carefully. Considering the multifactorial nature of POD, however, the integration of effective preventive strategies into multidisciplinary programs is advisable and should be the target for future research.

Review
BACKGROUND
The technology in the field of laparoscopy is rapidly evolving and is primarily focussed on increasing the quality of image and depth perception in the form of 4K and three-dimensional (3D) technology. There has been no conclusion yet regarding the better technology.
METHODS
A systematic search was performed independently by two authors across MEDLINE, Google Scholar and Embase using the PRISMA guidelines. All randomised control trials comparing 3D and 4K technologies were included. Meta-analysis was conducted using random-effects statistics for time taken for different tasks across the studies.
RESULTS
The search strategy revealed a total of 1835 articles, out of which nine studies were included. Three studies showed no superiority of 3D over 4K, while the remaining six did. Meta-analysis for the time taken for peg transfer favoured 3D over 4K (overall effect: Z = 2.12; P = 0.03). Forest plots for time taken for suturing (Z = 1.3; P = 0.19) and knot tying (Z = 1.7; P = 0.09) also favoured 3D over 4K; the results however were statistically insignificant. Path length was reported by two studies and was found to be lesser in the 3D group. Two studies measured the workload by NASA/Surg-TLX score, which was lower in the 3D group. Visual side effects were found to be higher in the 3D group.
CONCLUSION
3D technology is likely to result in a shorter operative time and better efficiency of movement as compared to the 4K technology by the virtue of its better depth perception.

OBJECTIVE
The suitable electrode array choice is broadly discussed in cochlear implantation surgery. Whether to use a shorter electrode length under the aim of structure preservation versus choosing a longer array to achieve a greater cochlear coverage is a matter of debate. The aim of this review is to identify the impact of the insertion depth of a cochlear implant (CI) electrode array on CI users' speech perception outcomes.
DATABASES REVIEWED
PubMed was searched for English-language articles that were published in a peer-reviewed journal from 1997 to 2022.
METHODS
A systematic electronic search of the literature was carried out using PubMed to find relevant literature on the impact of insertion depth on speech perception. The review was conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines of reporting. Studies in both, children and adults with pre- or postlingual hearing loss, implanted with a CI were included in this study. Articles written in languages other than English, literature reviews, meta-analyses, animal studies, histopathological studies, or studies pertaining exclusively to imaging modalities without reporting correlations between insertion depth and speech outcomes were excluded. The risk of bias was determined using the "Risk of Bias in Nonrandomized Studies of Interventions" tool. Articles were extracted by 2 authors independently using predefined search terms. The titles and abstracts were screened manually to identify studies that potentially meet the inclusion criteria. The extracted information included: the study population, type of hearing loss, outcomes reported, devices used, speech perception outcomes, insertion depth (linear insertion depth and/or the angular insertion depth), and correlation between insertion depth and the speech perception outcomes.
RESULTS
A total of 215 relevant studies were assessed for eligibility. Twenty-three studies met the inclusion criteria and were analyzed further. Seven studies found no significant correlation between insertion depth and speech perception outcomes. Fifteen found either a significant positive correlation or a positive effect between insertion depth and speech perception. Only 1 study found a significant negative correlation between insertion depth and speech perception outcomes.
CONCLUSION
Although most studies reported a positive effect of insertion depth on speech perception outcomes, one-third of the identified studies reported no correlation. Thus, the insertion depth must be considered as a contributing factor to speech perception rather than as a major decisive criterion.

International Ophthalmology Jul 2022To systematically review the published manuscripts on stereopsis after corneal refractive surgery. (Meta-Analysis)
Meta-Analysis Review
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; I = 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; I = 68.6%, P < 0.001).
CONCLUSIONS
Stereopsis improves after corneal refractive surgery in adults and pediatrics.
