Review
BACKGROUND
Eye movement disorders may affect over 70% of stroke patients. These eye movement disorders can result in difficulty maintaining the normal ocular position and difficulty moving the eyes appropriately. The resulting functional disabilities include a loss of depth perception, reduced hand-to-eye co-ordination, marked difficulties with near tasks and reading and reduced ability to scan the visual environment. They can also impact on the effectiveness of rehabilitation therapy. There are a wide variety of different treatment interventions proposed for eye movement disorders after stroke. However, in the past, there has been a lack of evidence specific to the impact of interventions on the functional outcome of patients with stroke.
OBJECTIVES
To determine the effects of interventions for eye movement disorders on functional ability following stroke.
SEARCH STRATEGY
We searched the Cochrane Stroke Group Trials Register (February 2011), the Cochrane Eyes and Vision Group Trials Register (December 2009) and nine electronic bibliographic databases including CENTRAL (The Cochrane Library 2009, Issue 4), MEDLINE (1950 to December 2009), EMBASE (1980 to December 2009), CINAHL (1982 to December 2009), AMED (1985 to December 2009), and PsycINFO (1967 to December 2009). We also searched reference lists and trials registers, handsearched journals and conference proceedings, and contacted experts.
SELECTION CRITERIA
Randomised trials in adults after stroke where the intervention was specifically targeted at improving the eye movement disorder or improving the ability of the participant to cope with the eye movement disorder. The primary outcome was functional ability in activities of daily living. Secondary outcomes included functional ability in extended activities of daily living, eye movement measures, balance, falls, depression or anxiety, discharge destination or residence after stroke, quality of life and social isolation, adverse events, and death.
DATA COLLECTION AND ANALYSIS
Two authors independently screened abstracts, extracted data and appraised trials. We undertook assessment of methodological quality for allocation concealment, blinding of outcome assessor, method of dealing with missing data, and other potential sources of bias.
MAIN RESULTS
Two studies (28 participants but only five were people with stroke) met the inclusion criteria and were included in this review. Both studies investigated pharmacological interventions for disorders of eye movement in patients with stroke. It was not appropriate to pool data and we were not able to draw conclusions from these studies. We found no other randomised studies which investigated interventions for disorders of eye movement in patients with stroke.
AUTHORS' CONCLUSIONS
There is insufficient evidence to reach conclusions about the effectiveness of interventions for patients with eye movement disorders after stroke. High quality research in the form of well-designed randomised trials are urgently required.

Review
BACKGROUND
Virtual reality (VR) is an interesting and promising way to teach cardiopulmonary resuscitation (CPR) to adult laypersons as its high immersive characteristics could improve the level of skills and acquired knowledge in learning basic life support (BLS).
METHODS
This systematic review assesses current literature about BLS training with VR and its possible effect on CPR-quality parameters, self-efficacy, perceived learning, and learners' satisfaction and short and long-term patients' outcome. We screened the Cochrane Library, PubMed, CINAHL, MEDLINE Ovid, Web of Science, and Scopus databases and included only clinical trials and quasi-experimental studies published from inception to October 1, 2021, which analyzed adult laypersons' BLS training with the use of VR. Primary outcomes were CPR parameters (chest compression rate and depth, Automated External Defibrillator use). Secondary outcomes were self-efficacy, perceived learning and learners satisfaction, and patients' outcomes (survival and good neurologic status). The risk of bias of included study was assessed using the Cochrane Handbook for Systematic Reviews of Interventions tool to evaluate randomized control trials and the transparent reporting of evaluations with nonrandomized designs checklist for nonrandomized studies.
RESULTS
After full article screening, 6 studies were included in the systematic review (731 participants) published between 2017 and 2021. Because of the heterogeneity of the studies, we focused on describing the studies rather than meta-analysis. The assessment of the quality of evidence revealed overall a very low quality. Training with VR significantly improved the rate and depth of chest compressions in 4 out of 6 articles. VR was described as an efficient teaching method, exerting a positive effect on self-efficacy, perception of confidence, and competence in 2 articles.
CONCLUSION
VR in BLS training improves manual skills and self-efficacy of adult laypersons and may be a good teaching method in a blended learning CPR training strategy. VR may add another way to divide complex parts of resuscitation training into easier individual skills. However, the conclusion of this review suggests that VR may improve the quality of the chest compressions as compared to instructor-led face-to-face BLS training.

Review
This systematic review provides an overview of augmented reality (AR) and its benefits in craniomaxillofacial surgery in an attempt to answer the question: Is AR beneficial for craniomaxillofacial surgery? This review includes a description of the studies conducted, the systems used and their technical characteristics. The search was performed in four databases: PubMed, Cochrane Library, Embase, and Web of Science. All journal articles published during the past 11 years related to AR, mixed reality, craniomaxillofacial, and surgery were considered in this study. From a total of 7067 articles identified using AR- and surgery-related keywords, 39 articles were finally selected. Based on these articles, a classification of study types, surgery types, devices used, metrics reported, and benefits were collected. The findings of this review indicate that AR could provide various benefits, addressing the challenges of conventional navigation systems, such as hand-eye coordination and depth perception. However, three main concerns were raised while performing this study: (1) it is complicated to aggregate the metrics reported in the articles, (2) it is difficult to obtain statistical value from the current studies, and (3) user evaluation studies are lacking. This article concludes with recommendations for future studies by addressing the latter points.

Meta-Analysis
Comparative Study of the Influence of Three-Dimensional Versus Two-Dimensional Urological Laparoscopy on Surgeons' Surgical Performance and Ergonomics: A Systematic Review and Meta-Analysis.
The objective of this study is to compare the use of three-dimensional (3D) vision systems with traditional two-dimensional systems in laparoscopic urological surgery, analyzing the benefits, limitations, and impact of introducing this medical technology with regard to surgical performance and the surgeon's ergonomics. A systematic review with a structured bibliographic search was conducted in the electronic libraries (PubMed and EMBASE) until August 2019 and with no language restrictions. Studies on 3D visualization technology in laparoscopic urologic surgery, randomized controlled trials, and observational comparative studies were included. Relevant data were extracted and analyzed. A total of 25 articles were obtained, of which 4 were clinical studies with patients, 2 studies were carried out in experimental animal models, and the remaining 19 were conducted in simulated environments. Regarding the European training program in basic laparoscopic urological skills, the results showed no significant differences in execution time using either imaging system. Three-dimensional vision led to a significant reduction in surgery time in pyeloplasty and radical nephrectomy. In addition, there was a reported decrease in blood loss in adrenalectomy, nephron-sparing nephrectomy, radical nephrectomy, simple nephrectomy, and pyeloplasty using 3D vision. Regarding ergonomics, the studies generally described no differences in side effects (headache, nausea, eye strain) when comparing the two types of visualization systems. Surgeons reported reduced workloads and stress with 3D vision than with traditional laparoscopy. Three-dimensional laparoscopic systems essentially advance surgical performance in less-experienced laparoscopic surgeons. Three-dimensional laparoscopy leads to improvements in surgery time, which is important for specific surgical procedures involving intracorporeal ligatures and sutures. The results achieved on the surgeons' ergonomics showed better depth perception and decreased stress and workloads during 3D vision with no differences in potential side effects.

Comparative Study Review
BACKGROUND
Laparoscopic surgery is widely used, and results in accelerated patient recovery time and hospital stay were compared with laparotomy. However, laparoscopic surgery is more challenging compared with open surgery, in part because surgeons must operate in a three-dimensional (3D) space through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception. To counter this problem, 3D imaging for laparoscopy was developed. A systematic review of the literature was performed to assess the effect of 3D laparoscopy.
METHODS
A systematic search of the literature was conducted to identify randomized controlled trials that compared 3D with 2D laparoscopy. The search was accomplished in accordance with the PRISMA guidelines using the PubMed, EMBASE, and The Cochrane Library electronic databases. No language or year of publication restrictions was applied. Data extracted were cohort size and characteristics, skill trained or operation performed, instrument used, outcome measures, and conclusions. Two independent authors performed the search and data extraction.
RESULTS
Three hundred and forty articles were screened for eligibility, and 31 RCTs were included in the review. Three trials were carried out in a clinical setting, and 28 trials used a simulated setting. Time was used as an outcome measure in all of the trials, and number of errors was used in 19 out of 31 trials. Twenty-two out of 31 trials (71%) showed a reduction in performance time, and 12 out of 19 (63%) showed a significant reduction in error when using 3D compared to 2D.
CONCLUSIONS
Overall, 3D laparoscopy appears to improve speed and reduce the number of performance errors when compared to 2D laparoscopy. Most studies to date assessed 3D laparoscopy in simulated settings, and the impact of 3D laparoscopy on clinical outcomes has yet to be examined.

Review
BACKGROUND
Excessive breast cancer screening with mammography or other modalities often burdens patients with false-positive results and costs. Yet, screening patients beyond the age at which they will benefit or at too frequent intervals persists. This review summarizes the factors associated with overuse of breast cancer screening.
METHODS
We searched Medline and Embase from January 1998 to March 2017 for articles addressing the overuse of breast cancer screening and hand-searched the reference lists of included articles. Studies were included if they were written in English, pertained to a U.S. population, and identified a factor associated specifically with overuse of breast imaging. Paired reviewers independently screened abstracts, extracted data, and assessed quality.
RESULTS
We included 15 studies: 3 cohort, 5 cross-sectional, 6 surveys, and 1 in-depth interview. White women (non-Hispanic) were less vulnerable than other racial groups to overuse in 3 of 5 studies. Physician specialty was consistently associated with screening overuse in three of three studies. Abundant access to primary care and a patient desire for screening were associated with breast cancer screening overuse. Lower self-confidence, lower risk taking tendencies, higher perception of conflict in expert recommendations, and a belief in screening effectiveness were clinician traits associated with overuse of screening in the surveys.
CONCLUSIONS
The literature supports that liberal access to care and clinicians' recommendations to screen, possibly influenced by conflicting guidelines, increase excessive breast cancer screening. Overuse might conceivably be reduced with more concordance across guidelines, physician education, patient involvement in decision-making, thoughtful insurance restrictions, and limitations on the supply of services; however, these will need careful testing regarding their impact.

Review
UNLABELLED
The aim of this systematic review was to synthesize and appraise the evidence of benefits of second-eye cataract extraction for visual function, patient-reported quality of life, falls, and driving ability among the elderly. We conducted a comprehensive search in MEDLINE using "surgery," "cataract extraction," "second eye," and "bilateral." Ten studies met the inclusion and quality criteria. We found "moderate" evidence supporting improvement in stereopsis, stereoacuity, and anisometropia over and above the benefits of first-eye surgery. We also found "moderate" evidence supporting improvement in visual acuity, contrast sensitivity, and self-reported visual functioning. Studies included in the review do not provide definitive evidence of second-eye surgery benefits on health-related quality of life, visual fields, falls prevention, and driving performance. However, the heterogeneity of outcome measures and the limited number of studies likely contributed to our findings. The findings have implications for clinicians and policymakers in the health-care industry and emphasize the need for additional trials examining this important and widely performed clinical procedure.

BACKGROUND
Globally, cardiovascular disease (CVD) accounts for 45% of all chronic non-communicable disease deaths and 31% of all deaths. CVD has remained the primary cause of death in the world for the past fifteen years. Compared to other continents, CVD and its risk factors are highly prevalent in Africa, but the continent also displays a low-level of knowledge and awareness of CVD, and poor perception of its risk factors. Little research has been done on the connection between the daily lived experiences of African people and the high prevalence and poor perception of CVD and its risk factors on the African continent. The aim of this study is to provide an in-depth understanding of the daily, lived experiences of African people and the connections between these experiences and the prevention, control, and management of CVD and its risk factors.
METHODS
A systematic search was performed in PubMed, CINAHL, EMBASE, Psych INFO, and Web of Science databases to identify published English qualitative studies of CVD and its risk factors. Qualitative metasynthesis included structured techniques of data immersion and quality appraisal, thematic synthesis, and reciprocal translation.
RESULTS
Seven studies met the inclusion criteria. Four major themes were identified from the metasynthesis: 1) understanding and beliefs about CVD; 2) perceived causes/risk factors for CVD; 3) understanding and belief about obesity; 4) perceived treatment options for CVD. The metasynthesis identified a consistent disconnect among African people between seeing CVD as a deadly and chronic disease and their perceptions of the minimal signs and symptoms of the disease in the early stages. This was further compounded by the gap between traditional healers and health care professionals.
CONCLUSIONS
Perceptions of CVD, its risk factors, and treatments were influenced by religious and cultural factors. Given the minimal signs and symptoms experienced in the early stages of the disease, there was a consistent disconnect among African people between seeing CVD as a deadly and chronic illness. Further investigations of the religious and cultural influences and educational programs related to these areas of disconnect are needed to improve the knowledge, attitudes, and beliefs of African people.

Review
AIM
The aim of this study was to synthesize qualitative research evidence on cancer survivors' experiences with reproductive concerns (RC).
METHODS
We conducted a systematic search of qualitative studies and utilized the meta-aggregation approach. The database searches were extended up to May 14, 2023, encompassing 12 databases, specifically MEDLINE, CINAHL, PubMed, EMBASE, Scopus, Web of Science (Core Collection), AMED, PsycINFO, The Cochrane Library, CNKI, Wan Fang Data, and VIP.
RESULTS
Three overarching themes were synthesized from the analysis of 21 studies that explored cancer patients' awareness of reproductive concerns, their perceptions, needs, and coping styles. These themes encapsulate the multifaceted aspects of cancer patients' reproductive concerns: "Gender differences in fertility concerns among cancer patients: Perspectives from men and women"; "The influence of age: Experiences with fertility issues among cancer patients at different life stages"; "The impact of treatment stages on fertility concerns: The evolution of perception and coping strategies in the course of cancer treatment".
CONCLUSION
Our study presents an in-depth exploration of the reproductive concerns experienced by cancer patients from various perspectives. We found that the internal experiences of reproductive concerns, their perceptions, needs, and coping mechanisms differ based on their roles. This comprehensive understanding of the complex emotions and needs of cancer patients when confronted with fertility issues can guide clinicians in providing more effective medical assistance, psychological counseling, and fertility-related information services.

Review
Augmented reality (AR) superimposes computer-generated virtual objects onto the user's view of the real world. Among medical disciplines, neurosurgery has long been at the forefront of image-guided surgery, and it continues to push the frontiers of AR technology in the operating room. In this systematic review, we explore the history of AR in neurosurgery and examine the literature on current neurosurgical applications of AR. Significant challenges to surgical AR exist, including compounded sources of registration error, impaired depth perception, visual and tactile temporal asynchrony, and operator inattentional blindness. Nevertheless, the ability to accurately display multiple three-dimensional datasets congruently over the area where they are most useful, coupled with future advances in imaging, registration, display technology, and robotic actuation, portend a promising role for AR in the neurosurgical operating room.
