Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patients, standard intraocular lens (IOL) decentration is a risk because of the enlarged sulcus and capsular bag. These unique circumstances make cataract surgery challenging. To date, several approaches have been developed. Implantation of a retropupillary iris-claw aphakic intraocular lens may be a good option because it is easier than suturing the IOL and can have better and more stable anatomic and visual outcomes, compared to other techniques.

The aim was to assess the impact of cataract surgeries in reducing visual disabilities and factors influencing it at three institutes of India. A retrospective chart review was performed in 2013. Data of 4 years were collected on gender, age, residence, presenting a vision in each eye, eye that underwent surgery, type of surgery and the amount the patient paid out of pocket for surgery. Visual impairment was categorized as; absolute blindness (no perception of light); blind (visual impairment (SVI) (visual impairment (6/18-6/60) and; normal vision (≥6/12). Statistically analysis was performed to evaluate the association between visual disabilities and demographics or other possible barriers. The trend of visual impairment over time was also evaluated. We compared the data of 2011 to data available about cataract cases from institutions between 2002 and 2009. There were 108,238 cataract cases (50.6% were female) that underwent cataract surgery at the three institutions. In 2011, 71,615 (66.2%) cases underwent surgery. There were 45,336 (41.9%) with presenting vision visual disability. The goal of improving vision related quality of life for cataract patients during the early stages of visual impairment that is common in industrialized countries seems to be non-attainable in the rural India.
Age-related cataract is one of the most important causes of visual impairment, and cataract surgery is one of the commonest surgeries performed worldwide. Femtosecond laser assisted cataract surgery (FLACS) is a new and promising technology in the arena of cataract operations. Femtosecond lasers (FSL) are used in ...

Congenital cataract is a common cause of blindness in children; however, its pathogenesis remains unclear. Genetic factors have been shown to play an important role in the pathogenesis of congenital cataract. The current genetic models of congenital cataract include autosomal dominant, autosomal recessive, and sex-linked inheritance. Sex-linked congenital cataract could be inherited through the X or Y chromosome. Congenital cataract is a symptom associated with several X-linked disorders, including Nance-Horan syndrome, Lowe syndrome, Conradi-Hünermann-Happle syndrome, oculo-facio-cardio-dental syndrome, and Alport syndrome. On the other hand, the mechanism and characteristics of Y-linked congenital cataract remains to be identified. Despite its rarity, sex-linked congenital cataract has been known to seriously affect the quality of life of patients. In this review, we present our current understanding of the genes and loci associated with sex-linked congenital cataract. This could help identify novel approaches for the prevention, early diagnosis, and comprehensive disease treatment.

Epidemiological studies suggest that antidepressants use may increase the risk of cataract, but the results are inconclusive. We aimed to examine this association by performing a systematic review and meta-analysis. Relevant studies were identified by searching PubMed and Web of Science databases through June 2017. We included studies that reported risk estimates for the association between antidepressants use and cataract risk. A random-effects model was used to calculate the summary odds ratio (OR) with its 95% confidence interval (CI). We identified seven studies of antidepressants use and risk of cataract involving 447,672 cases and 1,510,391 controls. Overall, the combined ORs (95% CIs) of cataract for selective serotonin reuptake inhibitors (SSRIs), serotonin noradrenalin reuptake inhibitors (SNRIs), and tricyclic antidepressants (TCAs) were 1.12 (1.06-1.19), 1.13 (1.04-1.24), and 1.19 (1.11-1.28), respectively. A certain degree of heterogeneity was observed across studies (P antidepressants use and risk of cataract. Because of the heterogeneity and limited eligible studies, further prospective studies are warranted to confirm the preliminary findings of our study.

Full Text Available The aim of the present systematic review was to examine the benefits and harms associated with immediate sequential bilateral cataract surgery (ISBCS with specific emphasis on the rate of complications, postoperative anisometropia, and subjective visual function in order to formulate evidence-based national Danish guidelines for cataract surgery. A systematic literature review in PubMed, Embase, and Cochrane central databases identified three randomized controlled trials that compared outcome in patients randomized to ISBCS or bilateral cataract surgery on two different dates. Meta-analyses were performed using the Cochrane Review Manager software. The quality of the evidence was assessed using the GRADE method (Grading of Recommendation, Assessment, Development, and Evaluation. We did not find any difference in the risk of complications or visual outcome in patients randomized to ISBCS or surgery on two different dates. The quality of evidence was rated as low to very low. None of the studies reported the prevalence of postoperative anisometropia. In conclusion, we cannot provide evidence-based recommendations on the use of ISBCS due to the lack of high quality evidence. Therefore, the decision to perform ISBCS should be taken after careful discussion between the surgeon and the patient.

Femtosecond laser-assisted cataract surgery (FLACS) has gained popularity in recent years with the new technology suggesting potential improvements in clinical and safety outcomes over conventional phacoemulsification cataract surgery (PCS). A decade since the advent of FLACS has given time and experience for laser technology to develop in maturity, and better quality evidence to become available. This review evaluates current evidence on the clinical and safety outcomes for FLACS in comparison to PCS. FLACS technology continues to improve and with it our confidence in tackling more complex patient indications. Concurrently other new technologies such as precision pulse capsulotomy also look to deliver the biomechanically ideal 5.2 mm capsulotomy, particularly as there remain suggestions from large studies and meta-analyses of raised capsular complications with FLACS compared with PCS and IOL technology responding to advantages of a consistent capsulotomy. Visual benefits of FLACS over and above PCS also remain to be conclusively demonstrated, with equivalence but not superiority. Economic modelling continues to indicate that FLACS remains 'not' cost-effective. FLACS can be considered non-inferior to conventional PCS in term of safety and clinical outcomes. However, FLACS has yet to demonstrate an overall cost-benefit to the patient.

Visual acuity is the measurement of an individual's ability to recognize details of an object in a space. Visual function measurements in clinical ophthalmology are limited by factors such as maximum contrast and so it might not adequately reflect the real vision conditions at that moment as well as the subjective aspects of the world perception by the patient. The objective of a successful vision-restoring surgery lies not only in gaining visual acuity lines, but also in vision quality. Therefore, refractive and cataract surgeries have the responsibility of achieving quality results. It is difficult to define quality of vision by a single parameter, and the main functional-vision tests are: contrast sensitivity, disability glare, intraocular stray light and aberrometry. In the current review the different components of the visual function are explained and the several available methods to assess the vision quality are described.

The expansion of research in physics in the last 100 years has been reflected in the expansion of the Physical Review(PR). Reviews of Modern Physics was the first ``new'' journal, starting in 1929. Physical Review Letters commenced in 1958, and was the first ``letters'' type of journal for important new results in all fields. By 1970 the Physical Review itself had grown so large that it was necessary to separate it by field into manageable volumes: PRA, PRB, PRC and PRD, and subsequently PRE, which was split off from PRA. More recently, two Special Topics journals for accelerator physics and physics education were pioneers of the open access business model, and the newest member of the family, Physical Review X, continues this trend. PRX is broad scope and very selective, setting it well above many of the new open access journals with a review standard of ``not incorrect.'' Some possible future directions for the Physical Review journals will be discussed.

To evaluate relevant clinical outcomes following a transzonular intravitreal injection of a compounded triamcinolone-moxifloxacin-vancomycin (TMV) formulation for postoperative prophylaxis after cataract surgery in a retrospective review of medical records from a private practice, single-specialty ambulatory center in New Jersey, USA. The analysis included 1541 cases from 922 patients who underwent cataract surgery with an intravitreal injection of TMV from November 2013 to December 2014. Cataract surgery was performed by a standard clear corneal phacoemulsification technique. Transzonular injection was used to deliver TMV directly into the anterior vitreous after implantation of an intraocular lens. There were no major intraoperative complications associated with the transzonular injection technique. There were no cases of postoperative endophthalmitis. Nearly 92% of cases (n = 1413/1541) did not require supplemental medication after surgery. The rate of breakthrough inflammation at Days 14-21 was 9.2% (n = 132/1429). The rate of visually significant postoperative cystoid macular edema was 2.0% (n = 28/1429). The rate of clinically significant postoperative intraocular pressure increase was low: 0.9% (n = 13/1425) of cases had an at least 10 mmHg increase at Days 14-21 or 90. Four of these cases had intraocular pressure at least 30 mmHg. The rates of infection and inflammation reported in this retrospective review of a transzonular injection of TMV for prophylaxis after cataract surgery appear similar to reported rates with alternative prophylactic therapies such as topical drops. The transzonular injection of TMV may have advantages in terms of patient compliance.

Ionizing radiation is a well-known but little understood risk factor for lens opacities. Until recently, cataract development was considered to be a deterministic effect occurring at lens doses exceeding a threshold of 5-8 Gy. Substantial uncertainty about the level and the existence of a threshold subsists. The International Commission on Radiation Protection recently revised it to 0.5 Gy. Based on a systematic literature review of epidemiological studies on exposure to low levels of ionizing radiation and the occurrence of lens opacities, a list of criteria for new epidemiological studies was compiled, and a list of potential study populations was reviewed. Among 24 publications finally identified, six report analyses of acute exposures in atomic bomb survivors and Chernobyl liquidators, and the others report analyses of protracted exposures in occupationally, medically or accidentally exposed populations. Three studies investigated a dose threshold: in atomic bomb survivors, the best estimates were 1 Sv (95 % CI <0-0.8 Sv) regarding lensectomies; in survivors exposed as children, 0.6 Sv (90 % CI <0.0-1.2 Sv) for cortical cataract prevalence and 0.7 Sv (90 % CI 0.0-2.8 Sv) for posterior subcapsular cataract; and in Chernobyl liquidators, 0.34 Sv (95 % CI 0.19-0.68 Sv) for stage 1 cataract. Current studies are heterogeneous and inconclusive regarding the dose-response relationship. Protracted exposures and high lens doses occur in several occupational groups, for instance, in physicians performing fluoroscopy-guided interventional procedures, and in accidentally exposed populations. New studies with a good retrospective exposure assessment are feasible and should be initiated. (orig.)
Full Text Available Technology has helped improve many aspects of the quality of publications: more visibility, greater access to sources of information and option to verify those sources, among others. This has meant that some journals have had to adjust their processes, especially peer reviewing. The blind mode is the method most commonly used by journals. In the case of our journal, we have traditionally used the double-blind style; however, we have noticed that, with advanced Internet, social networks, and media, it is easier for reviewers to obtain previews, preprints, primary research or previous articles that can help identify the author, thus making the double blind review difficult. These experiences have made us analyze whether the peer review system used by the journal is appropriate. Searching for other peer review options we found the open review. This paper briefly reviews some advantages and disadvantages of this type of review and the experience faced by this journal when implementing it.

Full Text Available AIM: To evaluate factors associated with the development of strabismus after cataract extraction and primary intraocular lens implantation.METHODS: The medical records of 122 patients, aged 1.5mo to 9y, who had undergone cataract extraction with primary intraocular lens implantation between January 1993 and August 2011 were reviewed. Fourteen patients (17 eyes with strabismus before cataract surgery were excluded. Patients were divided into those with congenital bilateral cataracts (64 patients, 128 eyes and those with unilateral cataracts (44 patients, 44 eyes. The associations between the development of strabismus and age at cataract surgery, pre- and post-cataract extraction corrected distance visual acuity (CDVA, interocular CDVA difference, nystagmus, surgical method, and secondary cataract were evaluated.RESULTS: Factors significantly associated with the development of strabismus included age at cataract surgery (≤1y, preoperative mean CDVA ≤20/100, presence of nystagmus in the bilateral cataract group and postoperative interocular CDVA difference ＞20/70 in the unilateral group. Postoperative CDVA ≤20/100 and preservation of posterior capsule, and presence of secondary cataract were significant factors in both groups.CONCLUSION: Children with congenital cataracts should be monitored carefully after cataract surgery for the development of strabismus, especially when they underwent surgery at age ≤1y, and they have nystagmus, large postoperative interocular CDVA difference, poor preoperative and postoperative CDVA, preservation of the posterior capsule, or secondary cataract.

Appropriate mydriasis is usually achieved by topical and/or intracameral administration of anticholinergic agents, sympathomimetic agents, or both, with the most commonly used being cyclopentolate, tropicamide, and phenylephrine. Ocular inflammation is common after cataract surgery. Topical steroids and nonsteroidal anti-inflammatory drugs are widely used because they have been proved effective to control postsurgical inflammation and decrease pain. Topical nonsteroidal anti-inflammatory drugs have also been shown to help maintain dilation. However, use of multiple preoperative drops for pupil dilation, inflammation, and pain control have been shown to be time consuming, resulting in delays to the operating room, and they cause dissatisfaction among perioperative personnel; their use can also be associated with systemic side effects. Therefore, ophthalmologists have been in search of new options to streamline this process. This article will review the current medications commonly used for intraoperative mydriasis, as well as pain and inflammation control. In addition, a new combination of ketorolac, an anti-inflammatory agent, and phenylephrine, a mydriatic agent has recently been designed to maintain intraoperative mydriasis and to reduce postoperative pain and irritation from intraocular lens replacement surgery.

Scientific peer review is pivotal in health care research in that it facilitates the evaluation of findings for competence, significance, and originality by qualified experts. While the origins of peer review can be traced to the societies of the eighteenth century, it became an institutionalized part of the scholarly process in the latter half of the twentieth century. This was a response to the growth of research and greater subject specialization. With the current increase in the number of specialty journals, the peer review process continues to evolve to meet the needs of patients, clinicians, and policy makers. The peer review process itself faces challenges. Unblinded peer review might suffer from positive or negative bias towards certain authors, specialties, and institutions. Peer review can also suffer when editors and/or reviewers might be unable to understand the contents of the submitted manuscript. This can result in an inability to detect major flaws, or revelations of major flaws after acceptance of publication by the editors. Other concerns include potentially long delays in publication and challenges uncovering plagiarism, duplication, corruption and scientific misconduct. Conversely, a multitude of these challenges have led to claims of scientific misconduct and an erosion of faith. These challenges have invited criticism of the peer review process itself. However, despite its imperfections, the peer review process enjoys widespread support in the scientific community. Peer review bias is one of the major focuses of today's scientific assessment of the literature. Various types of peer review bias include content-based bias, confirmation bias, bias due to conservatism, bias against interdisciplinary research, publication bias, and the bias of conflicts of interest. Consequently, peer review would benefit from various changes and improvements with appropriate training of reviewers to provide quality reviews to maintain the quality and integrity of

Cataract is one of the most important leading causes of blindness in the world. Extensive research showed that oxidative stress may play an important role in the initiation and progression of a cataract and other age-related eye diseases. Extra-generation of reactive oxygen and nitrogen species in the eye tissue has been shown as one of the most important risk factors for cataracts and other age-related eye diseases. With respect to this, it can be hypothesized that dietary antioxidants may be useful in the prevention and/or mitigation of cataract. Lutein is an important xanthophyll which is widely found in different vegetables such as spinach, kale and carrots as well as some other foods such as eggs. Lutein is concentrated in the macula and suppresses the oxidative stress in the eye tissues. A plethora of literature has shown that increased lutein consumption has a close correlation with reduction in the incidence of cataract. Despite this general information, there is a negligible number of review articles considering the beneficial effects of lutein on cataracts and age-related eye diseases. The present review is aimed at discussing the role of oxidative stress in the initiation and progression of a cataract and the possible beneficial effects of lutein in maintaining retinal health and fighting cataract. We also provide a perspective on the chemistry, sources, bioavailability and safety of lutein.

The importance of systematic reviews (SRs) as an aid to decision making in health care has led to an increasing interest in the development of this type of study. When selecting a target journal for publication, authors generally seek out higher impact factor journals. This study aimed to determine the percentage of scientific medical journals that publish SRs according to their impact factors (>2.63) and to determine whether those journals require tools that aim to improve SR reporting and meta-analyses. In our cross-sectional study showing how to choose the right journal for a SR, we selected and analysed scientific journals available in a digital library with a minimum Institute for Scientific Information impact factor of 2.63. We analysed 622 scientific journals, 435 (69.94%) of which publish SRs. Of those 435 journals, 135 (21.60%) provide instructions for authors that mention SRs. Three hundred journals (48.34%) do not discuss criteria for article acceptance in the instructions for authors section, but do publish SRs. Only 118 (27.00%) scientific journals require items to be reported in accordance with the specific SR reporting forms. The majority of the journals do not mention the acceptance of SRs in the instructions for authors section. Only a few journals require that SRs meet specific reporting guidelines, making interpretation of their findings across studies challenging. There is no correlation between the impact factor of the journal and its acceptance of SRs for publication. © 2014 John Wiley & Sons, Ltd.

With development of the technology of cataract surgery, combined phacoemulsification and intraocular lens implantation in cataract with high myopia has been widely carried out in clinical treatment. Due to the particularity of high myopia, phacoemulsification in patients with cataract and high myopia is difficult and has recently received a lot of attentions. In this paper, preoperative examinations, the selection of intraocular lenses, surgery methods and surgical complications of cataract surgery in patients with cataract and high myopia are briefly reviewed.

Early diagnosis and prompt surgical intervention is critical to prevent irreversible amblyopia. Thorough ocular evaluation, including the onset, duration, and morphology of a cataract, is essential to determine the timing for surgical intervention. Detailed assessment of the general health of the child, preferably in conjunction with a pediatrician, is helpful to rule out any associated systemic condition. Although pediatric cataracts have a diverse etiology, with the majority being idiopathic, genetic counseling and molecular testing should be undertaken with the help of a genetic counselor and/or geneticist in cases of hereditary cataracts. Advancement in surgical techniques and methods of optical rehabilitation has substantially improved the functional and anatomic outcomes of pediatric cataract surgeries in recent years. However, the phenomenon of refractive growth and the process of emmetropization have continued to puzzle pediatric ophthalmologists and highlight the need for future prospective studies. Posterior capsule opacification and secondary glaucoma are still the major postoperative complications necessitating long-term surveillance in children undergoing cataract surgery early in life. Successful management of pediatric cataracts depends on individualized care and experienced teamwork. We reviewed the etiology, preoperative evaluation including biometry, choice of intraocular lens, surgical techniques, and recent developments in the field of childhood cataract.

We show that when ecologists act as reviewers their reported rejection rates recommended for manuscripts increases with their publication frequency in high impact factor journals. Rejection rate however does not relate to reviewer age. These results indicate that the likelihood of getting a paper accepted for publication may depend upon factors in addition to scientific merit. Multiple reviewer selection for a given manuscript therefore should consider not only appropriate expertise, but also reviewers that have variable publication experience with a range of different journals to ensure balanced treatment. Interestingly since age did not relate to rejection rates, more senior scientists are not necessarily more jaded in reviewing practices. PMID:19621085

Congenital cataracts are opacities of the lens in one or both eyes of children, causing a reduction in vision bad enough to require surgery. Cataract is the largest preventable cause of visual loss in childhood. Paediatric cataracts provide different challenges to those in adults. Intense inflammation, amblyopia and posterior capsule opacification can affect results of treatment. Two treatments commonly considered for congenital cataract are lensectomy and lens aspiration. The objective of this review is to assess the effects of surgical treatments for bilateral symmetrical congenital cataracts. Success is measured according to the vision attained and occurrence of adverse events. We searched the Cochrane Controlled Trials Register - CENTRAL (which includes the Cochrane Eyes and Vision Group specialised register), MEDLINE, EMBASE, the Science Citation Index and the reference list of the included study. We also contacted trial investigators and experts in the field for details of further studies. We included all prospective, randomised controlled trials that compared one type of cataract surgery to another or to no surgery, in children aged 15 years or younger with bilateral congenital cataracts. Two reviewers extracted data. No meta-analysis was performed. One trial met the inclusion criteria. This trial randomised 130 eyes of 65 children. Follow up of 56 children at three years found no difference in visual acuity between lensectomy and lens aspiration with primary capsulotomy. Secondary opacification developed at a higher rate in the lens aspiration group (66%) compared to the lensectomy group (2%). The two methods of surgery for bilateral congenital cataracts in this review have good visual results but the incidences of side effects differ. Further randomised trials are required to inform modern practice.

Some peer reviewers may inappropriately, or coercively request that authors include references to the reviewers' own work. The objective of this study was to evaluate whether, compared to reviews for a journal with single-blind peer review, reviews for a journal with open peer review included (1) fewer self-citations; (2) a lower proportion of self-citations without a rationale; and (3) a lower ratio of proportions of citations without a rationale in self-citations versus citations to others' work. Peer reviews for published manuscripts submitted in 2012 to a single-blind peer review journal, the Journal of Psychosomatic Research, were previously evaluated (Thombs et al., 2015). These were compared to publically available peer reviews of manuscripts published in 2012 in an open review journal, BMC Psychiatry. Two investigators independently extracted data for both journals. There were no significant differences between journals in the proportion of all reviewer citations that were self-citations (Journal of Psychosomatic Research: 71/225, 32%; BMC Psychiatry: 90/315, 29%; p=.50), or in the proportion of self-citations without a rationale (Journal of Psychosomatic Research: 15/71, 21%; BMC Psychiatry: 12/90, 13%; p=.21). There was no significant difference between journals in the proportion of self-citations versus citations to others' work without a rationale (p=.31). Blind and open peer review methodologies have distinct advantages and disadvantages. The present study found that, in reasonably similar journals that use single-blind and open review, there were no substantive differences in the pattern of peer reviewer self-citations.

The Journal of Nuclear Materials achieves its scientific excellence through several familiar editorial activities. Manuscripts are submitted by authors describing their research methods and results, a constructive refereeing process is generously provided by peer reviewers, and the many steps and decisions of the editorial process are carried out by the Editors with assistance from the Advisory Editorial Board. With the exception of peer reviewers, the names of the people within these groups are published in the pages of the Journal. Thereby they receive recognition in the community for their work. However, all of us Journal constituents owe a large debt of gratitude to reviewers. They dedicate time, energy and remarkable depth of expertise to evaluate submitted manuscripts. As a result of their work most manuscripts are substantively improved. We also recognize the fact that many times the underlying research itself is advanced by the recommendations of our reviewers. Because the Journal maintains a strict policy of anonymous peer review, we do not make known the names of reviewers in association with particular manuscripts. Within this constraint the Editors and Publisher wish to find ways to recognize our reviewers. We recently instituted a top reviewer honor for a single individual, awarded at the NuMat conference (http://www.nuclearmaterialsconference.com)

Eye disturbance caused by atomic bomb radiation can be divided into three groups: direct injury immediately after exposure, eye lesions associated with radiation syndrome, and delayed disturbance. The crystalline lens of the eye is the most radiosensitive. Atomic bomb cataract has been investigated in a number of studies. The first section of this chapter discusses radiation cataract in terms of the incidence and characteristics. The second section deals with atomic bomb cataract, which can be diagnosed based on the four criteria: (1) opacity of the crystalline lens, (2) a history of proximal exposure, (3) lack of eye disease complicating cataract, and (4) non-exposure to radiation other than atomic bombing. The prevalence of cataract and severity of opacity are found to correlate with exposure doses and age at the time of exposure. Furthermore, it is found to correlate with distance from the hypocenter, the condition of shielding, epilation, and the presence or absence or degree of radiation syndrome. (N.K.)
Full Text Available Journal advertising is one of the main sources of medicines information to doctors. Despite the availability of regulations and controls of drug promotion worldwide, information on medicines provided in journal advertising has been criticized in several studies for being of poor quality. However, no attempt has been made to systematically summarise this body of research. We designed this systematic review to assess all studies that have examined the quality of pharmaceutical advertisements for prescription products in medical and pharmacy journals.Studies were identified via searching electronic databases, web library, search engine and reviewing citations (1950 - February 2006. Only articles published in English and examined the quality of information included in pharmaceutical advertisements for prescription products in medical or pharmacy journals were included. For each eligible article, a researcher independently extracted the data on the study methodology and outcomes. The data were then reviewed by a second researcher. Any disagreements were resolved by consensus. The data were analysed descriptively. The final analysis included 24 articles. The studies reviewed advertisements from 26 countries. The number of journals surveyed in each study ranged from four to 24 journals. Several outcome measures were examined including references and claims provided in advertisements, availability of product information, adherence to codes or guidelines and presentation of risk results. The majority of studies employed a convenience-sampling method. Brand name, generic name and indications were usually provided. Journal articles were commonly cited to support pharmaceutical claims. Less than 67% of the claims were supported by a systematic review, a meta-analysis or a randomised control trial. Studies that assessed misleading claims had at least one advertisement with a misleading claim. Two studies found that less than 28% of claims were unambiguous
Full Text Available Cataract refers to the degenerative changes in lens quality caused by various causes of reduced transparency or color change. Surgical treatment is the main treatment modality at present. Among them, phacoemulsification has become the main surgical treatment for cataract because of its advantages such as short operation time, small incision and quicker healing. Today, cataract surgery has gradually shift to refractive surgery, and is no longer simply as cataract surgery. But after cataract phacoemulsification, the symptoms and visual quality are different. The main causes include refractive error, postoperative dry eyes and postoperative corneal astigmatism. This article reviews the factors that influence the visual quality of cataract phacoemulsification and its future trends.

Although some research and publication practices are clearly unethical, including fraud and plagiarism, other areas of research and publication, such as informed consent and conflicts of interest, fall into grayer areas. The purposes of this article are, therefore, to review a variety of relevant ethical issues in radiology-related journalism, peer review, and research; to review the radiology literature to date that has addressed these issues; and to present position statements and potential solutions to these problems.

This paper is a report of a study to assess the beliefs and preferences of reviewers for nursing journals about blinding of authors to reviewers, reviewers to authors, neither or both. Blinding of author and reviewer names in the manuscript review process has been of interest to nursing editors, but reports that are based on data rather than simply opinion concern the editorial practices of biomedical rather than nursing journals. There has been no study of nursing journal reviewer beliefs and preferences related to blinding. A descriptive web-based survey was conducted. The sample included 1675 anonymous reviewers, recruited through 52 editors of nursing journals from their review panels. Data were collected in 2007. Double-blinding of reviews was the most common method reported. Ninety per cent of respondents reported that the papers they received to review did not include author names. When author names were blinded, 62% of reviewers could not identify the authors of papers; another 17% could identify authors Nursing journal reviewers are generally very satisfied with double-blinding and believe it contributes to the quality of papers published. Editors or editorial boards interested in a more open review process could consider alternatives such as offering authors and reviewers the option to unblind themselves. Simply announcing that the review process will henceforth be unblinded would probably lead to loss of reviewers.

To evaluate cases and results of keratomycosis that developed after cataract surgery. Hospital de Guipúzcoa, San Sebastián, Spain. This retrospective study comprised 8 patients who developed keratomycosis soon after cataract surgery. Culture analysis revealed 7 cases of Aspergillus fumigatus and 1 of Aspergillus flavus. After medical treatment with antifungal agents, 6 cases resolved and 2 required evisceration. The presence of fungi in corneal ulcers that develop after cataract surgery should be considered. Initiation of early treatment determines the prognosis. Among the therapeutic options, collagen shields soaked in amphotericin B may be effective.

Changes in iris color have been noted anecdotally after cataract surgery in infants, but they have not been studied systematically. The mechanism for these iris color changes has not previously been reported in the biomedical literature. Photographs were taken of both eyes of 15 children and 11 rhesus monkeys who had undergone unilateral cataract surgery. Masked examiners reviewed the photographs and compared the iris color of the eyes that were operated on with the eyes that were not operated on. Between 4 and 6 weeks postoperatively, the level of prostaglandin F(2alpha) in the aqueous humor (n = 4) and vitreous humor (n = 2) was measured in both the operated and nonoperated eyes of 4 monkeys that had undergone a neonatal lensectomy during the first 5 days of life. Thirteen of 15 children had a darker iris color in the operated eye in relation to the nonoperated (control) eye. Four of 11 monkeys had a uniformly darker iris in the operated eye; the other 7 monkeys had regional darkening or patches of darker iris in the eye that was operated on. The prostaglandin F(2alpha) levels in neonatal monkeys were higher in the aqueous humor and in the vitreous humor of the operated eye in relation to the nonoperated eye. In some children, cataract surgery is associated with a darkening of the iris color in the operated eye. We speculate that this darkening results from an exuberant prostaglandin release stimulated by the cataract surgery and may occur through the same or a similar mechanism by which latanoprost causes the darkening of iris color.

While preparation of a journal article for submission may often include informal review by colleagues, an article is not accepted for publication until it has been formally peer reviewed. Peer review is the process whereby journal editors ask expert reviewers to examine the work submitted and prepare a report on its suitability for publication. Two or more revisions of the article may be required following peer review, with the author reworking the article in the light of feedback received on each occasion. This can be challenging for some authors, but used well, it offers a chance to improve the work to the required standard of the journal, and help the author present a more precise and coherent account of the arguments. The extent to which the author responds to the critical commentary of peer reviewers is important, because this may determine whether or not the article is published. This article explores the aims of peer reviewers and recommends ways in which authors can respond to the feedback provided.
Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

Despite being a treatable disease, cataract is still the leading cause for blindness in the world. Solar ultraviolet radiation is epidemiologically linked to cataract development, while animal and in vitro studies prove a causal relationship. However, the pathogenetic pathways for the disease are not fully understood and there is still no perfect model for human age related cataract. This non-comprehensive overview focus on recent developments regarding effects of solar UV radiation wavebands on the lens. A smaller number of fundamental papers are also included to provide a backdrop for the overview. Future studies are expected to further clarify the cellular and subcellular mechanisms for UV radiation-induced cataract and especially the isolated or combined temporal and spatial effects of UVA and UVB in the pathogenesis of human cataract. Regardless of the cause for cataract, there is a need for advances in pharmaceutical or other treatment modalities that do not require surgical replacement of the lens. Copyright © 2016.

Peer reviewing for medical education journals is an art, a privilege, a responsibility and a service to the profession. Writing a review report requires skills and commitment and takes time. Novice reviewers may be interested in participating in this service, but they might lack sufficient knowledge of their role as peer reviewers and the skills needed to conduct a comprehensive and fair review. The aims of this article are to help novice reviewers in their preparation of manuscript review reports and improve their confidence and skills in their role as reviewers. We reviewed the literature in this area and applied lessons learned from our experience as peer reviewers. In addition, one of the authors has presented several training workshops for faculty reviewers. Incorporating all the methods described, we have developed a series of simple strategies that medical educators can utilise to perform high-quality reviews of manuscripts. Though the development of skills in reviewing medical education papers is the outcome of continuous practice and experience; the strategies described in this article will be of value to those starting their professional contribution as reviewers and enhance their skills in this area.

Purpose: To describe and discuss the processes used to write scholarly book reviews for publication in peer-reviewed journals and to provide a recommended strategy and book appraisal worksheet to use when conducting book reviews. Methods: A literature search of MEDLINE, EMBASE, CINAHL, and the Index to Chiropractic Literature was conducted in June 2009 using a combination of controlled vocabulary and truncated text words to capture articles relevant to writing scholarly book reviews for publication in peer-reviewed journals. Results: The initial search identified 839 citations. Following the removal of duplicates and the application of selection criteria, a total of 78 articles were included in this review including narrative commentaries (n = 26), editorials or journal announcements (n = 25), original research (n = 18), and journal correspondence pieces (n = 9). Discussion: Recommendations for planning and writing an objective and quality book review are presented based on the evidence gleaned from the articles reviewed and from the authors' experiences. A worksheet for conducting a book review is provided. Conclusions: The scholarly book review serves many purposes and has the potential to be an influential literary form. The process of publishing a successful scholarly book review requires the reviewer to appreciate the book review publication process and to be aware of the skills and strategies involved in writing a successful review.

Analyze the scientific production on Thanatology published in nursing journals. Systematic review, with quantitative approach, that aimed the characterization of the articles with regard to the year and journal of publication, and its Qualis CAPES, thematic approach, methodological focus, description of training area and qualification of authors. According to the selection criteria of the sample, 36 articles whose publication period was between the years 1986 and 2011 were extracted for analysis. It was noted the predominance of studies published in journals with high quality strata (A1 and A2), use of qualitative method and nurses educators as authors. The focus of the studies encompassed six central themes, and the prevailing ones were: "Thanatology in the academic training" and "The nurse in face of the dying process of patients and families under their cares". It is clear that the issue still presents itself in a timid manner, requiring an increased production on the subject.

Background Cataract surgery is practiced widely and substantial resources are committed to an increasing cataract surgical rate in developing countries. With the current volume of cataract surgery and the increases in the future, it is critical to optimize the safety and cost-effectiveness of this procedure. Most cataracts are performed on older individuals with correspondingly high systemic and ocular comorbidities. It is likely that routine preoperative medical testing will detect medical conditions, but it is questionable whether these conditions should preclude individuals from cataract surgery or change their perioperative management. Objectives (1) To investigate the evidence for reductions in adverse events through preoperative medical testing, and (2) to estimate the average cost of performing routine medical testing. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 12), MEDLINE (January 1950 to December 2011), EMBASE (January 1980 to December 2011), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to December 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 9 December 2011. We used reference lists and the Science Citation Index to search for additional studies. Selection criteria We included randomized clinical trials in which routine preoperative medical testing was compared to no preoperative or selective preoperative testing prior to age-related cataract surgery. Data collection and analysis Two review authors independently assessed abstracts to identify possible trials for inclusion. For each included study, two review authors

Full Text Available BACKGROUND: Peer review is considered crucial to the selection and publication of quality science, but very little is known about the previous experiences and training that might identify high-quality peer reviewers. The reviewer selection processes of most journals, and thus the qualifications of their reviewers, are ill defined. More objective selection of peer reviewers might improve the journal peer review process and thus the quality of published science. METHODS AND FINDINGS: 306 experienced reviewers (71% of all those associated with a specialty journal completed a survey of past training and experiences postulated to improve peer review skills. Reviewers performed 2,856 reviews of 1,484 separate manuscripts during a four-year study period, all prospectively rated on a standardized quality scale by editors. Multivariable analysis revealed that most variables, including academic rank, formal training in critical appraisal or statistics, or status as principal investigator of a grant, failed to predict performance of higher-quality reviews. The only significant predictors of quality were working in a university-operated hospital versus other teaching environment and relative youth (under ten years of experience after finishing training. Being on an editorial board and doing formal grant (study section review were each predictors for only one of our two comparisons. However, the predictive power of all variables was weak. CONCLUSIONS: Our study confirms that there are no easily identifiable types of formal training or experience that predict reviewer performance. Skill in scientific peer review may be as ill defined and hard to impart as is "common sense." Without a better understanding of those skills, it seems unlikely journals and editors will be successful in systematically improving their selection of reviewers. This inability to predict performance makes it imperative that all but the smallest journals implement routine review ratings

Cataract extraction in children has improved and became more popular over the past few decades but, due to particular features of children's eyes, still remains controversial--especially regarding the intraocular lens implantation. In contrast to adults, indications for cataract surgery in children are much more difficult to determine. Since subjective visual acuity cannot be obtained, greater reliance must be placed on the morphology and location of the lens opacity, and the behavior of the child. Forced preferential looking and visual evoked potentials can be helpful, but they should not be the only criteria. In management of pediatric cataract, correction of postoperative aphakia is still an incompletely resolved problem. Conventionally, optical correction is achieved by spectacles or contact lenses. The power of both spectacles and contact lenses can be readily adjusted to compensate for ocular growth. The success of both depends significantly on parental compliance and the child's acceptance. Hutchinson reported that 44% children with aphakia stopped wearing glasses or contact lenses 2 months after surgery. Contact lens wearing can also result in a number of corneal complications, including infectious keratitis, corneal vascularization and hypoxic corneal ulceration. IOL implantation is theoretically superior to glasses and contact lenses since it provides almost immediate optical correction which is much more reliable because it does not depend on parental or child's compliance. Still, there are many controversies about IOL implantation in infants and young children like IOL-size, material, IOL power calculation, prevention and management of secondary cataract, as well as long term safety of IOLs in children's eyes. Although short-term anatomic results after cataract extraction and primary IOL implantation in children are excellent and stable, long-term follow-up is necessary to answer questions about the long-term safety of implants in children's eyes.

To evaluate the long-term visual outcomes and complications of cataract surgery in eyes previously treated for retinoblastoma. We reviewed the medical records of patients who underwent cataract extraction and intraocular lens implantation at Seoul National University Children's Hospital for a secondary cataract that developed after retinoblastoma treatment. During the period between 1990 and 2014, 208 eyes of 147 patients received eye-salvaging treatment (radiotherapy, chemotherapy, and local therapy) for retinoblastoma at Seoul National University Children's Hospital. Among these eyes, a secondary cataract was detected in 17 eyes of 14 patients, and five eyes of five patients underwent cataract surgery. The median age of cataract formation was 97 months (range, 38 to 153 months). The medial interval between the diagnosis of retinoblastoma and cataract formation was 79 months (range, 29 to 140 months). All patients received posterior chamber intraocular lens insertion after irrigation and aspiration of the lens through a scleral tunnel incision. Anterior vitrectomy and posterior capsulotomy were performed in two eyes and a laser capsulotomy was subsequently performed in one eye. No intraoperative and postoperative complications occurred. The median follow-up after surgery was 36 months (range, 14 to 47 months). The final best corrected visual acuities were improved in all five eyes. No intraocular tumor recurrences or metastases occurred. After retinoblastoma regression, cataract extraction in our series was not associated with tumor recurrence or metastasis. Visual improvement was noted in every patient.

Survey research is an important research method used to determine individuals' attitudes, knowledge, and behaviors; however, as with other research methods, inadequate reporting threatens the validity of results. This study aimed to describe the quality of reporting of surveys published between 2001 and 2011 in the field of nephrology. The top nephrology journals were systematically reviewed (2001-2011: American Journal of Kidney Diseases, Nephrology Dialysis Transplantation, and Kidney International; 2006-2011: Clinical Journal of the American Society of Nephrology) for studies whose primary objective was to collect and report survey results. Included were nephrology journals with a heavy focus on clinical research and high impact factors. All titles and abstracts were screened in duplicate. Surveys were excluded if they were part of a multimethod study, evaluated only psychometric characteristics, or used semi-structured interviews. Information was collected on survey and respondent characteristics, questionnaire development (e.g., pilot testing), psychometric characteristics (e.g., validity and reliability), survey methods used to optimize response rate (e.g., system of multiple contacts), and response rate. After a screening of 19,970 citations, 216 full-text articles were reviewed and 102 surveys were included. Approximately 85% of studies reported a response rate. Almost half of studies (46%) discussed how they developed their questionnaire and only a quarter of studies (28%) mentioned the validity or reliability of the questionnaire. The only characteristic that improved over the years was the proportion of articles reporting missing data (2001-2004: 46.4%; 2005-2008: 61.9%; and 2009-2011: 84.8%; respectively) (Pnephrology journals remains suboptimal. In particular, reporting of the validity and reliability of the questionnaire must be improved. Guidelines to improve survey reporting and increase transparency are clearly needed.

The primary functions of peer reviewers are poorly defined. Thus far no body of literature has systematically identified the roles and tasks of peer reviewers of biomedical journals. A clear establishment of these can lead to improvements in the peer review process. The purpose of this scoping review is to determine what is known on the roles and tasks of peer reviewers. We will use the methodological framework first proposed by Arksey and O'Malley and subsequently adapted by Levac et al and the Joanna Briggs Institute. The scoping review will include all study designs, as well as editorials, commentaries and grey literature. The following eight electronic databases will be searched (from inception to May 2017): Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Educational Resources Information Center, EMBASE, MEDLINE, PsycINFO, Scopus and Web of Science. Two reviewers will use inclusion and exclusion criteria based on the 'Population-Concept-Context' framework to independently screen titles and abstracts of articles considered for inclusion. Full-text screening of relevant eligible articles will also be carried out by two reviewers. The search strategy for grey literature will include searching in websites of existing networks, biomedical journal publishers and organisations that offer resources for peer reviewers. In addition we will review journal guidelines to peer reviewers on how to perform the manuscript review. Journals will be selected using the 2016 journal impact factor. We will identify and assess the top five, middle five and lowest-ranking five journals across all medical specialties. This scoping review will undertake a secondary analysis of data already collected and does not require ethical approval. The results will be disseminated through journals and conferences targeting stakeholders involved in peer review in biomedical research. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

To describe and discuss the processes used to write scholarly book reviews for publication in peer-reviewed journals and to provide a recommended strategy and book appraisal worksheet to use when conducting book reviews. A literature search of MEDLINE, EMBASE, CINAHL, and the Index to Chiropractic Literature was conducted in June 2009 using a combination of controlled vocabulary and truncated text words to capture articles relevant to writing scholarly book reviews for publication in peer-reviewed journals. The initial search identified 839 citations. Following the removal of duplicates and the application of selection criteria, a total of 78 articles were included in this review including narrative commentaries (n = 26), editorials or journal announcements (n = 25), original research (n = 18), and journal correspondence pieces (n = 9). Recommendations for planning and writing an objective and quality book review are presented based on the evidence gleaned from the articles reviewed and from the authors' experiences. A worksheet for conducting a book review is provided. The scholarly book review serves many purposes and has the potential to be an influential literary form. The process of publishing a successful scholarly book review requires the reviewer to appreciate the book review publication process and to be aware of the skills and strategies involved in writing a successful review.

To determine the value of serial personal photographs in timing the onset of unilateral cataracts in children over 6 months of age. Personal photographs from children with unilateral cataracts who underwent cataract extraction and intraocular lens implantation when > or =6 months of age were reviewed. Photographs were evaluated for changes in the red reflex, which might indicate the presence of a cataract. Twelve children underwent cataract surgery at a mean age of 37 months. They were followed for a mean of 32 months. Ten children were diagnosed as having an acquired cataract by photographic review documenting a previously normal red reflex. The visual acuity in the affected eye of 4 of these children improved to > or =20/60. Cataracts were visible on photographs prior to clinical diagnosis in 6 patients, from 0.5 to 22 months prior to clinical diagnosis. Visual outcomes did not relate closely to the photographically documented duration of the cataract prior to treatment. Photographs were not helpful in timing the onset of cataract in 2 children due to the poor quality of the images. Serial personal photographs are sometimes helpful in determining whether cataracts are acquired. However, the usefulness of personal photographs alone in predicting the visual outcome after cataract surgery was limited in this small, retrospective study.

To review recent data on blindness and low vision due to cataract in Latin America. Presentation of findings from population-based prevalence surveys conducted between 1999 and 2006 in nine Latin American countries covering 30,544 people aged 50 years and older. Prevalence of cataract blindness in people 50 years and older ranged from 0.5% in Buenos Aires to 2.3% in four provinces of Guatemala. Low vision from cataract ranged from 0.9% in Buenos Aires to 10.7% in Piura and Tumbes Districts in Peru. Cataract surgical coverage (CSC) was good in Campinas, Brazil; low in Paraguay, Peru, and Guatemala; and moderate in the other areas. Good visual outcome after cataract surgery nearly conformed to World Health Organization (WHO) guidelines in Buenos Aires (more than 80% of operated eyes able to see 20/60 or better), but ranged from 60% to 79% in most of the other settings, and was less than 60% in Guatemala and Peru. "Unaware that treatment is possible," "contraindications," "cannot afford," and "fear of operation" were the most common explanations for failure to come forward for surgery. In Campinas, Brazil, cataract is fairly well controlled. In Buenos Aires, the visual outcomes after cataract surgery nearly meet WHO standards. In most countries in Latin America, however, cataract intervention needs to be intensified and visual outcome improved. Reducing the costs of cataract surgery and providing effective health education and adequate program management are essential to combat the expected increase in visual impairment due to cataract in the region.

Full Text Available UNLABELLED: All the opinions in this article are those of the authors and should not be construed to reflect, in any way, those of the Department of Veterans Affairs. BACKGROUND: Our study purpose was to assess the predictive validity of reviewer quality ratings and editorial decisions in a general medicine journal. METHODS: Submissions to the Journal of General Internal Medicine (JGIM between July 2004 and June 2005 were included. We abstracted JGIM peer review quality ratings, verified the publication status of all articles and calculated an impact factor for published articles (Rw by dividing the 3-year citation rate by the average for this group of papers; an Rw>1 indicates a greater than average impact. RESULTS: Of 507 submissions, 128 (25% were published in JGIM, 331 rejected (128 with review and 48 were either not resubmitted after revision was requested or were withdrawn by the author. Of 331 rejections, 243 were published elsewhere. Articles published in JGIM had a higher citation rate than those published elsewhere (Rw: 1.6 vs. 1.1, p = 0.002. Reviewer quality ratings of article quality had good internal consistency and reviewer recommendations markedly influenced publication decisions. There was no quality rating cutpoint that accurately distinguished high from low impact articles. There was a stepwise increase in Rw for articles rejected without review, rejected after review or accepted by JGIM (Rw 0.60 vs. 0.87 vs. 1.56, p<0.0005. However, there was low agreement between reviewers for quality ratings and publication recommendations. The editorial publication decision accurately discriminated high and low impact articles in 68% of submissions. We found evidence of better accuracy with a greater number of reviewers. CONCLUSIONS: The peer review process largely succeeds in selecting high impact articles and dispatching lower impact ones, but the process is far from perfect. While the inter-rater reliability between individual
Full Text Available Abstract Background Growing popularity of complementary and alternative medicine (CAM in the public sector is reflected in the scientific community by an increased number of research articles assessing its therapeutic effects. Some suggest that publication biases occur in mainstream medicine, and may also occur in CAM. Homeopathy is one of the most widespread and most controversial forms of CAM. The purpose of this study was to compare the representation of homeopathic clinical trials published in traditional science and CAM journals. Methods Literature searches were performed using Medline (PubMed, AMED and Embase computer databases. Search terms included "homeo-pathy, -path, and -pathic" and "clinical" and "trial". All articles published in English over the past 10 years were included. Our search yielded 251 articles overall, of which 46 systematically examined the efficacy of homeopathic treatment. We categorized the overall results of each paper as having either "positive" or "negative" outcomes depending upon the reported effects of homeopathy. We also examined and compared 15 meta-analyses and review articles on homeopathy to ensure our collection of clinical trials was reasonably comprehensive. These articles were found by inserting the term "review" instead of "clinical" and "trial". Results Forty-six peer-reviewed articles published in a total of 23 different journals were compared (26 in CAM journals and 20 in conventional journals. Of those in conventional journals, 69% reported negative findings compared to only 30% in CAM journals. Very few articles were found to be presented in a "negative" tone, and most were presented using "neutral" or unbiased language. Conclusion A considerable difference exists between the number of clinical trials showing positive results published in CAM journals compared with traditional journals. We found only 30% of those articles published in CAM journals presented negative findings, whereas over twice

Clear and logical eligibility criteria are fundamental to the design and conduct of a systematic review. This methodological review examined the quality of reporting and application of eligibility criteria in systematic reviews published in three leading medical journals. All systematic reviews in the BMJ, JAMA and The Lancet in the years 2013 and 2014 were extracted. These were assessed using a refined version of a checklist previously designed by the authors. A total of 113 papers were eligible, of which 65 were in BMJ, 17 in The Lancet and 31 in JAMA. Although a generally high level of reporting was found, eligibility criteria were often problematic. In 67% of papers, eligibility was specified after the search sources or terms. Unjustified time restrictions were used in 21% of reviews, and unpublished or unspecified data in 27%. Inconsistency between journals was apparent in the requirements for systematic reviews. The quality of reviews in these leading medical journals was high; however, there were issues that reduce the clarity and replicability of the review process. As well as providing a useful checklist, this methodological review informs the continued development of standards for systematic reviews. © 2015 John Wiley & Sons, Ltd.

The peer review process for scientific journals relies on the efforts of volunteer reviewers. Reviewers are selected due to their expertise in their fields. With so many demands on professional time, the benefits of participating in peer review may not be obvious. However, reviewers benefit by exposure to the latest developments in their fields, facilitating their keeping up-to-date with the latest publications. Tenure committees look favorably on participation in peer review, and invitations to review underscore that the reviewer is a respected subject matter expert. Contacts made during the peer review process can lead to long-lasting collaboration. Continuing medical education credit can be obtained through various mechanisms. Overall, participating in peer review is an important part of career development and should be viewed as a critical component of advancement.
Full Text Available Purpose: To evaluate the outcome of phacoemulsification in eyes with subluxated cataract. Materials and Methods: This retrospective study comprised 22 eyes of 20 consecutive patients with subluxated cataracts of varying aetiology operated between March 1998 and March 2001. Detailed preoperative assessment included visual acuity (VA, slitlamp examination, presence of vitreous in anterior chamber, extent of subluxation, intraocular pressure (IOP and detailed fundus examination. Phacoemulsification was done to retain the natural bag support and all patients had acrylic foldable Acrysof IOL implantation either in-the-bag or by scleral fixation. Postoperative observations included best-corrected visual acuity (BCVA, IOP, pupillary reaction and the IOL position. Results: The aetiology of the subluxation was traumatic in 11 patients and non-traumatic in 9 patients. Fifteen were males and 5 were females. Mean follow-up was 11.7 ± 9.71 months (range 4-39. The average age was 39.15 ± 16.33 (range 5 - 74. A 2-port anterior chamber vitrectomy was performed in 6 eyes (27.2%. Capsule tension ring (CTR was implanted in 15 eyes (68.18%. Twelve eyes (54.5% had in-the-bag implants, while 5 (22.72% had scleral fixation. The remaining 5 eyes (22.72% had one haptic in-the-bag and another sutured to sclera. No major intraoperative complications were noted. Twelve eyes (54.5% had clinically and geometrically well centered IOLs while 9 eyes (40.9% had geometrically decentered IOLs. One patient was lost to follow-up. Fifteen eyes (55.55% had postoperative BCVA of 6/12 - 6/6 while 2 eyes (7.40% had BCVA of 6/18. The remaining 4 eyes (14.81% had less than 6/24 BCVA due to pre-existing posterior segment pathology. Postoperative complications included rise in IOP in 1 eye (4.54%, pupillary capture of the IOL optic in 2 eyes (9.09%; the same 2 eyes (9.09% required redialing of IOL.

This review outlines the advantages and the differences of femtosecond laser-assisted cataract surgery (FLACS) following a coaxial or microincision cataract surgery phacoemulsification in the surgical outcome and greater control of cataract surgery. FLACS offers minimal tissue damage and extreme precision during corneal incision creation, continuous circular capsulorhexis (CCC) and nuclear fragmentation. It also allows diminishing the mean average ultrasound power to emulsify the nucleus followed by a coaxial or a biaxial procedure. The impact of reduced phacoemulsification energy on the corneal endothelium is an interesting topic that is being investigated. Despite its benefits, this technology has relevant financial issues and a high learning curve. FemtoMICS appears to be surgically and statistically more efficient than the FemtoCoaxial technique and Femtoincisions prove to be stable and do not change the corneal high order aberration significantly with favorable results of the triplanar configuration.

The radiation-induced cataract has been up to now considered as a quite rare pathology, needing high-dose radiations (beyond a dose threshold roughly estimated at 2 Grays to the lens) consisting mainly in head tumour radiotherapy complications. Several new studies on different exposed populations such as astronauts, japanese atomic bomb survivors, people undergoing X-ray examinations, Chernobyl accident 'liquidators' as well as data from animal experiments, suggest that dose threshold for detectable opacities as well as for clinical posterior sub-capsular cataract occurring, might be far lower than those previously assumed. Even the existence of a dose threshold is no longer an absolute certitude insofar as radiation-induced cataract pathogenesis might consist not really in a deterministic effect (direct tissue harmful effect, killing or seriously injuring a critical population of cells) as believed until now, but rather in a stochastic effect (genomic damage in target-cells, altered cell division, abnormal lens fiber cell differentiation). More practically, these new data may lead us to reconsider radioprotection of specifically exposed populations: mainly patients and workers. Regarding workers, labour legislation (lens equivalent dose limit of 150 mSv during 12 consecutive months) might be, in the medium term, reassessed downwards. (author)

Full Text Available Amblyopia should always be anticipated in children with unilateral cataract, asymmetrical bilateral cataracts (or where there is a delay between the first and second eye operation, or a delay of more than a year between diagnosis/ detection and surgery, cataracts with anisometropia or traumatic cataracts with corneal scars. When amblyopia is detected, occlusion therapy (eye patching must be instituted at the earliest opportunity. The patching regimen is the same with any strabismic amblyopia and sometimes needs to be aggressive at the start. It is crucial to explain the need for patching to the parents, since compliance is the greatest obstacle to the success of amblyopia treatment.

We report on a 20 year old male, who developed mature cataract (Electrical Cataract) on both eyes after a severe electric shock from high voltage. Both of his hands and the left foot had to be amputated, because of the severe injury. Although electrical cataract due to high voltage or lightning is rare, they may still occur after industrial or home electric accidents. Even if extracapsular cataract extraction with intraocular lens implantation is successfully performed, the final visual acuity will depend on other ocular damage due to the electric current.

We included randomized controlled trials (RCTs) of participants who had open-angle, pseudoexfoliative, or pigmentary glaucoma and age-related cataract. The comparison of interest was combined cataract surgery (phacoemulsification) and any type of glaucoma surgery versus cataract surgery (phacoemulsification) alone. Two review authors independently assessed study eligibility, collected data, and judged risk of bias for included studies. We used standard methodological procedures expected by the Cochrane Collaboration. We included nine RCTs, with a total of 655 participants (657 eyes), and follow-up periods ranging from 12 to 30 months. Seven trials were conducted in Europe, one in Canada and South Africa, and one in the United States. We graded the overall quality of the evidence as low due to observed inconsistency in study results, imprecision in effect estimates, and risks of bias in the included studies.Glaucoma surgery type varied among the studies: three studies used trabeculectomy, three studies used iStent® implants, one study used trabeculotomy, and two studies used trabecular aspiration. All of these studies found a statistically significant greater decrease in mean IOP postoperatively in the combined surgery group compared with cataract surgery alone; the mean difference (MD) was -1.62 mmHg (95% confidence interval (CI) -2.61 to -0.64; 489 eyes) among six studies with data at one year follow-up. No study reported the proportion of participants with a reduction in the number of medications used after surgery, but two studies found the mean number of medications used postoperatively at one year was about one less in the combined surgery group than the cataract surgery alone group (MD -0.69, 95% CI -1.28 to -0.10; 301 eyes). Five studies showed that participants in the combined surgery group were about 50% less likely

There were 90 articles published in the Journal of Cardiovascular Magnetic Resonance (JCMR) in 2012, which is an 8% increase in the number of articles since 2011. The quality of the submissions continues to increase. The editors are delighted to report that the 2011 JCMR Impact Factor (which is published in June 2012) has risen to 4.44, up from 3.72 for 2010 (as published in June 2011), a 20% increase. The 2011 impact factor means that the JCMR papers that were published in 2009 and 2010 were cited on average 4.44 times in 2011. The impact factor undergoes natural variation according to citation rates of papers in the 2 years following publication, and is significantly influenced by highly cited papers such as official reports. However, the progress of the journal's impact over the last 5 years has been impressive. Our acceptance rate is approximately 25%, and has been falling as the number of articles being submitted has been increasing. In accordance with Open-Access publishing, the JCMR articles go on-line as they are accepted with no collating of the articles into sections or special thematic issues. For this reason, the Editors have felt that it is useful once per calendar year to summarize the papers for the readership into broad areas of interest or theme, so that areas of interest can be reviewed in a single article in relation to each other and other recent JCMR articles. The papers are presented in broad themes and set in context with related literature and previously published JCMR papers to guide continuity of thought in the journal. We hope that you find the open-access system increases wider reading and citation of your papers, and that you will continue to send your quality manuscripts to JCMR for publication.

Purpose To determine the cataract surgery techniques performed in Iran from 2000 to 2005. Materials and Methods This study was part of the Iranian Cataract Surgery Survey (ICSS) which was a retrospective cross-sectional study. All major ocular surgery units and 10% of randomly selected minor units throughout Iran were included. Excluding the 2 week Iranian New Year holiday, 1 week per season between 2000 and 2005 (a total of 24 weeks) was selected for each center, and data on all cataract surgeries performed during these weeks were collected by reviewing patient records. The ANOVA repeated measure test was performed to determine longitudinal changes with a P0.05). Conclusion Phacoemulsification with IOL implantation has become the preferred cataract surgery method in Iran during recent years. PMID:21731326

Full Text Available PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords "benign prostatic hyperplasia", "intraoperative floppy iris syndrome", "adrenergic alpha-antagonist" and "cataract surgery". In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2009. RESULTS: The first report of intraoperative floppy iris syndrome (IFIS was observed during cataract surgery in patients taking systemic alpha-1 AR antagonists in 2005. It has been most commonly seen related to use of tamsulosin. Changes of medication and washout periods of up to 2 weeks have been attempted to reduce the risk of complications in the setting of cataract surgery. CONCLUSION: Patients under clinical treatment for BPH should be informed about potential risks of this drug class so that it can be discuss with their healthcare providers, in particular urologist and ophthalmologist, prior to cataract surgery.

We aimed to assess the endorsement of the Consolidation Standards of Reporting Trials (CONSORT) statement by Chinese journals of Traditional Chinese Medicine (TCM) and its incorporation into their editorial processes. PubMed, Embase and major Chinese databases were searched to identify journals of TCM from China for inclusion. The latest 'instruction for authors' (IFA) of each included journal was obtained and any text mentioning CONSORT or CONSORT extension papers was extracted. Subsequently, the editor of each of the included journals was surveyed about their journal's endorsement of the CONSORT recommendations and their incorporation into editorial and peer review processes. Sixty-three journals of TCM from China were examined. Of these, only three (5%) and one (2%) of the 63 journals mentioned the CONSORT statement and extension papers, respectively, in their IFA. Fifty-four of 63 (86%) of surveyed journals responded, with the majority of respondents being editors. Only 20% (11/54) of the respondents reported that they had any knowledge of the CONSORT statement. Only 6% (3/54) of the editors reported that they required authors to comply with the CONSORT statement or that they incorporated it into their peer review and editorial processes. TCM journals in China endorsing the CONSORT statement constituted a small percentage of the total. The majority of editors surveyed were not familiar with the content of the CONSORT statement and extension papers. We strongly recommend that the China Periodicals Association issue a policy to promote the endorsement of the CONSORT statement and conduct relevant training for journal editors in China.

Alzheimer disease (AD) is a progressive neurodegenerative disease and is a leading cause of dementia among elders. In the early phase of AD, even if neuropathological changes presented, but little to none clinical symptoms were found. Therefore, it is difficult to diagnose AD in the beginning of the disease. It is vital to find a noninvasive way for both diagnose and prognosis of AD. Studies have found that β-amyloid (Aβ) works as a connection between AD and cataract. This review will discuss AD and its associated markers which may be present in the lens and cataract related AD to provide more basis for early diagnosis of AD.

Background Systematic reviews may provide less biased evidence than narrative reviews because they observe a strict methodology, similarly to primary studies. Hence, for clinical research questions, systematic reviews should be the study design of choice. It would be important to evaluate the prevalence and characteristics of narrative and systematic reviews published in prominent medical journals. Researchers and clinicians give great value to articles published in such scientific journals. ...

To review the visual outcome of traumatic cataracts operated at the University College Hospital, Ibadan with the view to making recommendations for improved outcome. All patients operated at the University College Hospital Ibadan, Nigeria between May 1999 and April 2004 with traumatic cataract were reviewed retrospectively to determine visual outcome and main causes of poor visual outcome notes of patients 32 patients, age range 2 to 71 years, mean age 25.6 +/- SD 16.1 years were reviewed. 22 (68.8%) were males while 10 (31.2%) were females. Causes of traumatic cataract included wood/stick splinters in 7 (21.9%), cane/whiplash injury 6 (18.8%), and propelled missile injuries, 5 (15.6%). Less important cause of injuries were gun shot, road traffic accident and fist injuries. 11 (35.6%) of the patients had best corrected post operative visual acuity of >6/18, 10 (32.2%) noted.

Essentials Reporting guidelines and trial/review registration aim to limit bias in research. We systematically reviewed hematology journals to examine the use of these policies. Forty-eight percent of journals made no use of these policies. Improving the use of reporting guidelines will improve research for all stakeholders. Background Reporting guidelines and trial/review registration policies have been instituted in order to minimize bias and improve research practices. Objective The objective of this study was to investigate the policies of hematology journals concerning reporting guideline adoption and trial/review registration. Methods We performed a web-based data abstraction from the Instructions for Authors of 67 hematology journals catalogued in the Expanded Science Citation Index of the 2014 Journal Citation Reports to identify whether each journal required, recommended or made no mention of the following reporting guidelines: EQUATOR, ICMJE, CONSORT, MOOSE, QUOROM, PRISMA, STARD, STROBE, ARRIVE and CARE. We also extracted whether journals required or recommended trial or systematic review registration. We e-mailed editors three times to determine which types of studies their journal accepts. Results Forty-eight per cent (32/67) of hematology journals do not adhere to any reporting guidelines. For responding journals, the QUOROM statement, MOOSE, CARE and PROSPERO were the least often mentioned, whereas the ICMJE guidelines, CONSORT statement and general trial registration were most often mentioned. Discussion Reporting guidelines are infrequently required or recommended by hematology journals. Furthermore, few require clinical trial or systematic review database registration. A higher rate of adherence to reporting guidelines can prevent bias from entering the literature. Participation from all stakeholders, including authors and journal editors, to improve reporting guideline and policy practices is required. © 2017 International Society on Thrombosis

Manuscripts submitted to journals should be understandable even to those who are not experts in a particular field. Moreover, they should use publicly available materials and the results should be verifiable and reproducible. Readers and reviewers will want to check the strengths and weaknesses of the research study design, and ways to make this determination should be clear through proper analysis methods. Studies should be described in detail so as to help readers understand the results. Statistical analysis is one of the key methods by which to do this. The inappropriate application of statistical methods could be misleading to readers and clinicians. While many researchers describe their general research methods in detail, statistical methods tend to be described briefly, with certain omissions or errors or other incorrect aspects. For instance, researchers should describe whether the median or mean was used, whether parametric or nonparametric tests were used, whether the data meet the normality test, whether confounding factors were corrected, and whether stratification or matching methods were used. Statistical analysis regardless of the program should be reported correctly. The results may be less reliable if the statistical assumptions before applying the statistical method are not met. These common errors in statistical methods originate from the researcher's lack of knowledge of statistics and/or from the lack of any statistical consultation. The aim of this work is to help researchers know what is important statistically and how to present it in papers.
Full Text Available Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

The present study aims to review the quality of open-access nursing journals listed in the Directory of Open Access Journals that published papers in 2013 with a nursing focus, written in English, and were freely accessible. Each journal was reviewed in relation to their publisher, year of commencement, number of papers published in 2013, fee for publication, indexing, impact factor, and evidence of requirements for ethics and disclosure statements. The quality of the journals was assessed by impact factors and the requirements for indexing in PubMed. A total of 552 were published in 2013 in the 19 open-access nursing journals that met the inclusion criteria. No journals had impact factors listed in Web of Knowledge, but three had low Scopus impact factors. Only five journals were indexed with PubMed. The quality of the 19 journals included in the review was evaluated as inferior to most subscription-fee journals. Mental health nursing has some responsibility to the general public, and in particular, consumers of mental health services and their families, for the quality of papers published in open-access journals. The way forward might involve dual-platform publication or a process that enables assessment of how research has improved clinical outcomes. © 2014 Australian College of Mental Health Nurses Inc.

There is a positive association between availability of regional peer-reviewed public health information systems and progressive change in community and population health. The objective of this brief report was to identify public health journals in Arabic-speaking countries actively publishing as of 2016. We conducted an electronic search in several electronic database records for public health journals using a combination of search terms. We excluded journals that focused on human medicine, veterinary medicine, nursing, and other discipline-specific or clinical health professions. We identified twenty-five public health journals for review. Five journals were interrupted or discontinued. Only three journals had a consistent, uninterrupted active publication history of greater than 20 years. Most journals were not in the regional native language. Introduction of regional public health-dedicated journals with in-print and electronic availability and also to be published in region-native languages may require interdisciplinary partnerships. Region-wide public health journals such as the Eastern Mediterranean Health Journal could serve as an ideal model for the establishment of additional local and regional public health journals in Arabic-speaking countries.

The purpose of this article was to review recent advances in the applications of nanotechnology in cataract treatment and prevention strategies. A literature review on the use of nanotechnology for the prevention and treatment of cataract was done. Research articles about nanotechnology-based treatments and prevention technologies for cataract were searched on Web of Science, and the most recent advances were reported. Nonsteroid anti-inflammatory drugs, natural antioxidants, biologic and chemical chaperones, and chaperones such as molecules have found great application in preventing and treating cataracts. Current scientific research on new treatment strategies, which focuses on the biochemical basis of the disease, will likely result in new anticataract agents. However, none of the drug formulations will be approved for use unless efficient delivery is promised. Nanoparticle engineering together with biomimetic strategies enable the development of next-generation, more efficient, less complex, and personalized treatments. The only currently available treatment for cataracts, surgical replacement of the opacified lens, is not an easily accessible option in developing countries. New treatment strategies based on topical drugs would enable treatment to reach massive populations facing the threat of blindness and more effectively deal with the postsurgical complications. Nanotechnology plays a key role in improving drug delivery systems with enhanced controlled release, targeted delivery, and bioavailability to overcome diffusion limitations in the eye.
Full Text Available In this article, an online student journal is described, and the ways in which student participants value the journal are discussed. Press Start is a peer-reviewed international journal of game studies, which aims to publish the best student work related to the academic study of video games. Content analysis of qualitative survey data (n = 29 provides insights into what students value about the journal, revealing six broad themes: community and support, inclusiveness and accessibility, the published research, feedback from peer review, experience of conducting peer review and the opportunity to publish. The article concludes by suggesting that engagement with online student journals should not be limited in terms of geography or the level of study, unless there are robust pedagogical reasons for doing so.
Full Text Available Background/Aim. Oxidative stress results from increased oxidative processes, decreased antioxidative protection, or both processes simultaneously. Photooxidative stress, as a form of oxidative stress, induced by the energy of solar radiation, today is considered as crucial in the age-related cataractogenesis. Other known and unknown, endogenous and egsogenous factors that contribute to the oxidative stress intensity, can influence the cataract type and brunescence. Thus the oxidative stress intensity and its form might determine the cataract type and brunescence, and also make the efforts in cataract prevention more complex. Hence, the objective of the present paper was to investigate the current amount of antioxidative capacity in aqueous humour during the cataract genesis of different types and pigmentation of cataract. Methods. Transversal review of 80 samples of humour aqueous obtained during extracapsular cataract extraction. Aqueouses were analyzed by tiobarbituric acid (TBA method for the total antioxidant activity estimation, expressed as %iMDA, and by using 0.1 ml of aqueous. Results. The mixed type of cataract showed the statistically significantly lower values of the intensities of antioxidative protection in aqueous humour compared to cortical and nuclear cataracts (p < 0.001, respectively. Between pure nuclear and cortical cataracts we found the small differences of the investigated parameter, but they pointed to the decreased level of antioxidative protection, i.e. the increased intensity of the aqueous humour oxidative stress in the cortical cataract type. A significant correlation between the cortical cataract maturation and the %iMDA (p < 0.05 was found. Conclusions. The role of the oxidative stress, here expressed as the antioxidative capacity of aqueous humour, could not be the same for all the cataract types. The lower level of antioxidative protection of aqueous in brunescent and mixed cataracts may point to the higher

Full Text Available Impact Factor (IF is considered as one of the most common subjects in academic environments. Individuals who would like to publish their productions and/or research results confront with various indicators, brands and labels that indicate relative importance, academic discipline and quality of journals. Diversity of the indicators induces confusion to select applicable journals and often, the authors would not be able to distinguish IF, ISI and their relations with the acceptance of the journal. Meanwhile, they have difficulties to find IF. Hence, this short paper aimed to provide useful information for authors to familiarize them with the concept of IF.

Peer review is the backbone of the scientific process. In 2016 a total of 866 scientist provided reviewer services for the International Journal Applied Earth Observation and Geoinformation. Frequent reviewers receive a recognition from the publisher in form of a Certificate of Outstanding Contribution in Reviewing and receive a 30 days free access to Scopus and ScienceDirect. More importantly they gain first hand insight into the latest developments in science as they are the first to read exciting new scientific papers. Nevertheless it is hard to find reviewers as the number of papers submitted to our journal has increased substantially over the last years and more remote sensing journals are put in the market each year. We are grateful to all those individuals that have devoted their precious time to reviewing papers for JAG. This has improved the quality of our communications which is well reflected in the number of citations our papers receive and the impact factor of the journal. JAG ranks third of all 28 remote sensing journals not the least because of the quality of the reviews we provide. As a token of our appreciation it is my pleasure to thank all reviewers that were active in 2016 on behalf of the editorial board, the associate editors, the Publisher and myself as Editor-in-Chief of JAG. To honor them we list all reviewers that provide four or more reviews in 2016:

Even in as small a country as R. Macedonia with limited resources allocated for science, there are many journals trying to establish good editorial practices and policies in publishing the scientific work achieved. Among the currently existing medical journals Macedonian Medical Review (MMR), ISSN 0025-1097, deserves to be elaborated as the oldest journal with continuous publication since its first appearance as the journal of the Macedonian Medical Association (MMA). Since its first issue, published in 1946, there has been an opus of some 4500 peer-reviewed published papers in more than 210 issues and some 80 supplements from various congresses and meetings. In this regard, great respect should be paid not only to the editorial boards, but also to the collaborators who have contributed to its successful continuity in all previous years. In line with the needs for further development of the journal and possibilities for access to world databases, the Editorial Board of MMR has made every effort to improve and modernize its work as well as the technical quality of the journal. Hence, MMA has signed a contract with De Gruyter Open as leading publisher of Open Access academic content for further improvement and promotion of the journal and facilitation of the Medline application, so we do hope for the further success of the journal. BANTAO Journal is published on behalf of the Balkan Cities Association of Nephrology, Dialysis, Transplantation and Artificial Organs (BANTAO), ISSN 1312-2517. The first issue was published in 2003, ten years after BANTAO was born. Its appearance was an extremely important event in the existence of BANTAO. The first official editor of the journal was Dimitar Nenov, Varna (2003-2005), followed by Ali Basci (Izmir, Turkey) and Goce Spasovski (Skopje, Macedonia) as editor-in-chief since 2009. Over the years, the Journal has been included in the EBSCO, DOAJ and SCOPUS/SCIMAGO databases. The journal is published biannually. Until now, 345

The use of the femtosecond laser (FSL) in cataract surgery may represent the largest advancement in the field since the inception of phacoemulsification. The goal of this review is to outline the benefits of and barriers to this technology. There are several significant potential benefits of the FSL in cataract surgery over conventional manual cataract surgery: precise capsulotomy formation, clear corneal and limbal relaxing incision construction, lens fragmentation, and lens softening. Evidence suggests that refractive benefits include more precise effective lens position as well as reduced effective phacoemulsification time with the use of FSL compared with manual surgery. Patients with conditions such as Fuchs' endothelial dystrophy, pseudoexfoliation, history of trauma, or brunescent cataracts may particularly benefit from this technology. There are significant financial and logistical issues to consider prior to the purchase of a FSL, including the cost of the laser, and charges to patients, and how the laser affects the patient flow in the operating room. The FSL may significantly change the current approach to cataract surgery.
Full Text Available Pre-publication peer review of manuscripts should enhance the value of research publications to readers who may wish to utilize findings in clinical care or health policy-making. Much published research across all medical specialties is not useful, may be misleading, wasteful and even harmful. Reporting guidelines are tools that in addition to helping authors prepare better manuscripts may help peer reviewers in assessing them. We examined journals' instructions to peer reviewers to see if and how reviewers are encouraged to use them.We surveyed websites of 116 journals from the McMaster list. Main outcomes were 1 identification of online instructions to peer reviewers and 2 presence or absence of key domains within instructions: on journal logistics, reviewer etiquette and addressing manuscript content (11 domains.Only 41/116 journals (35% provided online instructions. All 41 guided reviewers about the logistics of their review processes, 38 (93% outlined standards of behaviour expected and 39 (95% contained instruction about evaluating the manuscript content. There was great variation in explicit instruction for reviewers about how to evaluate manuscript content. Almost half of the online instructions 19/41 (46% mentioned reporting guidelines usually as general statements suggesting they may be useful or asking whether authors had followed them rather than clear instructions about how to use them. All 19 named CONSORT for reporting randomized trials but there was little mention of CONSORT extensions. PRISMA, QUOROM (forerunner of PRISMA, STARD, STROBE and MOOSE were mentioned by several journals. No other reporting guideline was mentioned by more than two journals.Although almost half of instructions mentioned reporting guidelines, their value in improving research publications is not being fully realised. Journals have a responsibility to support peer reviewers. We make several recommendations including wider reference to the EQUATOR Network

Full Text Available Background: In the final push toward the elimination of avoidable blindness, cataract occupies a position of eminence for the success of the Right to Sight initiative. Aims: Review existing situation and assess what monitoring indicators may be useful to chart progress towards attaining the goals of Vision 2020. Settings and Design: Review of published papers from low and middle income countries since 2000. Materials and Methods: Published population-based data on prevalence of cataract blindness/visual impairment were accessed and prevalence of cataract blindness/visual impairment computed, where not reported. Data on prevalence of cataract blindness, cataract surgical coverage at different visual acuity cut offs, surgical outcomes, and prevalence of cataract surgery were analyzed. Scatter plots were used to look at relationships of some variables, with Human Development Index (HDI rank. Available data on Cataract Surgical Rate (CSR was plotted against prevalence of cataract surgery reported from surveys. Results: Worse HDI Ranks were associated with higher prevalence of cataract blindness. Most studies showed that a significant proportion of the blind were covered by surgery, while a fifth showed that a significant proportion, were operated before they went blind. A good visual outcome after surgery was positively correlated with higher surgical coverage. CSR was positively correlated with cataract surgical coverage. Conclusions: Cataract surgical coverage is increasing in most countries at vision <3/60 and visual outcomes after cataract surgery are improving. Establishing population-based surveillance of cataract surgical need and performance is a strong monitoring tool and will help program planners immensely.
Full Text Available As a routine measure to prevent intraocular inflammation, rinsing conjunctival sac with povidone-iodine(PVP-Ihas been increasingly adopted in cataract surgery. It can effectively reduce the complications of cataract surgery, including endophthalmitis and corneal complications. However, PVP-I itself has certain side effects. Therefore, to achieve the best bactericidal effect and to avoid eye injury, it is necessary to find out the optimal treatment duration and concentration. This article offers a review on the latest researches worldwide in this field.

To determine the incidence of and associated risk factors for uveitis after cataract surgery. A total of 17,757 eyes were identified and records of 42 eyes that developed uveitis and 2320 eyes that did not were reviewed. Postsurgical uveitis was defined as persistent inflammation for ≥ 6 months after surgery. Forty-two eyes of 35 patients developed uveitis (0.24%). Eleven patients underwent consecutive cataract surgery but developed unilateral uveitis, and intraoperative complications occurred in 55% of uveitic eyes compared to 0% in fellow eyes (p < 0.05). Median duration of inflammation was 8 and 11.5 months in eyes with and without vitrectomy (p < 0.05). Intraocular complications occurred in 44 and 8.3% of eyes that did and did not develop uveitis, respectively (p = 0.01). Postsurgical uveitis developed after approximately 1 in 400 cataract surgeries and occurred more frequently in eyes experiencing intraoperative complications.

It is commonly believed that the peer-review process is reliable and consistent. It appears, however, that depending on the journal and the editorial leadership, agreement by reviewers on whether to publish submitted articles varies widely; from substantial to slightly greater than one would expect with random assignments of acceptance or rejection. The purpose was to assess peer-review agreement in major spine journals. This study is for the assessment of reviewer agreement. The study consisted of consecutive reviews of 200 submitted articles. Agreement via Kappa statistics. Group A consisted of 200 consecutive article reviews for which the senior author was involved in the review or editorial process over the past 8 years for two major spine journals. Reviewers' recommendations were placed into one of two groups: accept/minimal revisions or major revision/reject. Standard Kappa statistics were used to assess reviewer agreement. Group B consisted of a similar set, but with wholly randomly generated recommendations. Again, Kappa statistics were used. Kappa for Group A was 0.155 with a range of 0.017 to 0.294 at 95% confidence interval and agreement at 0.6; suggesting "slight" reviewer agreement. Kappa for Group B behaved as expected, with "poor" agreement. Agreement regarding peer-review recommendations for publication in spine journals appears to be better than would be expected in the random situation; but still only "slight." This suggests that review methodology varies considerably among reviewers and that further study should be undertaken to determine "ideal" agreement levels and ways to increase review consistency/quality commensurate with the editorial missions of the journals.

To examine the relationships between blindness, the intervention of cataract surgery and all-cause mortality in a rural Ethiopian population. Population-based, interventional prospective study. Community-based detection methods identified blind Ethiopian persons from two selected kebeles in Amhara region, Ethiopia. Data from 1201 blind patients were collected-628 cataract-blind and 573 blind from other conditions. Free cataract surgery was provided for consenting, cataract-blind patients. Follow-up surveys were conducted after 12 months (±1 month)-the main outcome measure for this report is all-cause mortality at 1 year. During the follow-up period, 110 persons died from the selected population (mortality 9.2%), which consisted of those cataract-blind patients who received cataract surgery (N=461), cataract-blind patients who did not receive surgery (N=167) and all non-cataract-blind patients (N=573). Of the 461 patients who received cataract surgery, 44 patients died (9.5%). Of the 740 patients who did not receive surgery, 66 died (8.9%)-28 patients from the cohort of cataract-blind patients who did not receive surgery (16.8%) and 38 patients from the cohort of non-cataract blind (6.6%). Subgroup analysis revealed significantly increased odds of mortality for cataract-blind patients over 75 years of age who did not receive surgery and for unmarried patients of all age groups. In this population, mortality risk was significantly elevated for older cataract-blind patients when compared with non-cataract-blind patients-an elevation of risk that was not noted in an age-matched cohort of cataract-blind patients who underwent cataract surgery as early as 1-year follow-up.

The aim of this study was to investigate the reporting completeness of systematic review (SR) abstracts in leading dental specialty journals. Electronic and supplementary hand searching were undertaken to identify SRs published in seven dental specialty journals and in the Cochrane Database of Systematic Reviews. Abstract reporting completeness was evaluated using a checklist derived from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (prisma) guidelines. Descriptive statistics followed by univariate and multivariate analyses were conducted. Two-hundred and eighteen SR abstracts were identified. Reporting of interventions (94%), objectives (96%), data sources (81%), eligibility criteria (77%), and conclusions (97%) was adequate in the majority of reviews. However, inadequate reporting of participants (18%), results (42%), effect size (14%), level of significance (60%), and trial registration (100%) was commonplace. The mean overall reporting score was 79.1% (95% CI, 77.6-80.6). Only journal of publication was a significant predictor of overall reporting, with inferior results for all journals relative to Cochrane reviews, with scores ranging from -4.3% (95% CI, -8.74 to 0.08) to -35.6% (95% CI, -42.0 to -24.3) for the International Journal of Prosthodontics and the British Journal of Oral and Maxillofacial Surgery, respectively. Improved reporting of dental SR abstracts is needed and should be encouraged, as these abstracts may underpin influential clinical decisions. © 2013 Eur J Oral Sci.

To describe the most common canine breeds affected with cataracts in Rio de Janeiro. Three hundred and three dogs were included in this retrospective study. Animal ages ranged from 6 months to 14.8 years. All records of dogs seen by the Ophthalmology Service of Policlínica Veterinária Botafogo between January 2005 and June 2008 were reviewed. Animals with cataracts were separated, and breed and age were evaluated. Most of the dogs presented with cataracts were Toy Poodles with a mean age of 8.2 years, followed by Cocker Spaniels and Bichon Frises. The percentage of Toy Poodles affected with cataracts was 13.8% while 33.3% of Bichon Frise was diagnosed with cataracts. Toy Poodles are a popular breed in Rio de Janeiro. Without regulations on breeding, the prevalence of cataracts may increase rapidly. Furthermore, due to the relatively late onset of cataract formation in the Toy Poodle (mean 8.2 years of age), affected animals may have produced several litters of puppies. This study emphasizes the importance of screening for the presence of inherited ocular abnormalities such as cataracts prior to breeding.

We undertook this investigation to characterize conflict of interest (COI) policies of biomedical journals with respect to authors, peer-reviewers, and editors, and to ascertain what information about COI disclosures is publicly available. We performed a cross-sectional survey of a convenience sample of 135 editors of peer-reviewed biomedical journals that publish original research. We chose an international selection of general and specialty medical journals that publish in English. Selection was based on journal impact factor, and the recommendations of experts in the field. We developed and pilot tested a 3-part web-based survey. The survey included questions about the presence of specific policies for authors, peer-reviewers, and editors, specific restrictions on authors, peer-reviewers, and editors based on COI, and the public availability of these disclosures. Editors were contacted a minimum of 3 times. The response rate for the survey was 91 (67%) of 135, and 85 (93%) of 91 journals reported having an author COI policy. Ten (11%) journals reported that they restrict author submissions based on COI (e.g., drug company authors' papers on their products are not accepted). While 77% report collecting COI information on all author submissions, only 57% publish all author disclosures. A minority of journals report having a specific policy on peer-reviewer 46% (42/91) or editor COI 40% (36/91); among these, 25% and 31% of journals state that they require recusal of peer-reviewers and editors if they report a COI. Only 3% of respondents publish COI disclosures of peer-reviewers, and 12% publish editor COI disclosures, while 11% and 24%, respectively, reported that this information is available upon request. Many more journals have a policy regarding COI for authors than they do for peer-reviewers or editors. Even author COI policies are variable, depending on the type of manuscript submitted. The COI information that is collected by journals is often not published

Poison centers advance knowledge in the field of toxicology through publication in peer-review journals. This investigation describes the pattern of poison center-related publications. Cases were poison center-related research published in peer-review journals during 1995-2014. These were identified through searching the PubMed database, reviewing the tables of contents of selected toxicology journals, and reviewing abstracts of various national and international meetings. The following variables for each publication were identified: year of publication, journal, type of publication (meeting abstract vs. other, i.e. full article or letter to the editor), and the country(ies) of the poison center(s) included in the research. Of the 3147 total publications, 62.1% were meeting abstracts. There were 263 publications in 1995-1999, 536 in 2000-2004, 999 in 2005-2009, and 1349 in 2010-2014. The publications were in 234 different journals. The journals in which the highest number of research was published were Clinical Toxicology (69.7%), Journal of Medical Toxicology (2.2%), and Veterinary and Human Toxicology (2.1%). The research was reported from 62 different countries. The countries with the highest number of publications were the United States (67.9%), United Kingdom (6.5%), Germany (3.9%), France (2.5%), and Italy (2.4%). The number of publications increased greatly over the 20 years. Although the publications were in a large number of journals, a high proportion of the publications were in one journal. While the research came from a large number of countries, the preponderance came from the United States. © The Author(s) 2015.

To analyse systematic review articles published in the top 10 nursing journals to determine the quality of the methods employed within them. Systematic review is defined as a scientific research method that synthesises high-quality scientific knowledge on a given topic. The number of such reviews in nursing science has increased dramatically during recent years, but their methodological quality has not previously been assessed. A review of the literature using a narrative approach. Ranked impact factor scores for nursing journals were obtained from the Journal Citation Report database of the Institute of Scientific Information (ISI Web of Knowledge). All issues from the years 2009 and 2010 of the top 10 ranked journals were included. CINAHL and MEDLINE databases were searched to locate studies using the search terms 'systematic review' and 'systematic literature review'. A total of 39 eligible studies were identified. Their methodological quality was evaluated through the specific criteria of quality assessment, description of synthesis and strengths and weaknesses reported in the included studies. Most of the eligible systematic reviews included several different designs or types of quantitative study. The majority included a quality assessment, and a total of 17 different criteria were identified. The method of synthesis was mentioned in about half of the reviews, the most common being narrative synthesis. The weaknesses of reviews were discussed, while strengths were rarely highlighted. The methodological quality of the systematic reviews examined varied considerably, although they were all published in nursing journals with a high-impact factor. Despite the fact that systematic reviews are considered the most robust source of research evidence, they vary in methodological quality. This point is important to consider in clinical practice when applying the results to patient care. © 2013 Blackwell Publishing Ltd.
Full Text Available Lola Elizabeth Lawuyi, Avinash Gurbaxani Moorfields Eye Hospital Dubai, Dubai, UAE Abstract: The maintenance of mydriasis throughout cataract extraction surgery and the control of ocular inflammation are crucial for successful surgical outcomes. The development of miosis during cataract surgery compromises the visualization of the surgical field and working space for surgeons. This may lead to complications that include posterior capsular tear and associated vitreous loss, longer surgical time, and postoperative inflammation. Postoperative inflammation is often uncomfortable and frustrating for patients. It causes pain, redness, and photophobia. This compromises the best-uncorrected vision following surgery and often leads to multiple clinic visits. This article examines the literature published on the current treatments used to manage mydriasis, pain, and inflammation in cataract extraction surgery. Combination phenylephrine/ketorolac injection offers an exciting new class of medication for use in cataract surgery. With the recent approval of Omidria™ (combination of phenylephrine 1% and ketorolac 0.3% by the US Food and Drug Administration (FDA for intraocular use, we review the clinical utility of this new combination injection in cataract surgery. PubMed, MEDLINE, and conference proceedings were searched for the relevant literature using a combination of the following search terms: cataract extraction surgery, pupil dilation (mydriasis, miosis, phenylephrine, ketorolac, Omidria™, intracameral mydriatic. Relevant articles were reviewed and their references checked for further relevant literature. All abstracts were reviewed and full texts retrieved where available.

Patients having cataract surgery have often earlier undergone a trabeculectomy for glaucoma. However, cataract surgery may be associated with failure of the previous glaucoma surgery and antimetabolites may be used with cataract surgery to prevent such failure. There is no systematic review on whether antimetabolites with cataract surgery prevent failure of a previous trabeculectomy. To assess the effects of antimetabolites with cataract surgery on functioning of a previous trabeculectomy. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 5), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to June 2014), EMBASE (January 1980 to June 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to June 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 10 June 2014. We also searched the Science Citation Index database (July 2013) and reference lists of potentially relevant studies. Randomised controlled trials (RCTs) of antimetabolites with cataract surgery in people with a functioning trabeculectomy. Two review authors independently reviewed the titles and abstracts from the electronic searches. Two review authors independently assessed relevant full-text articles and entered data. We identified no RCTs to test the effectiveness of antimetabolites with cataract surgery in individuals with the intention of preventing failure of a previous trabeculectomy. There are no RCTs of antimetabolites with cataract surgery in people with a functioning trabeculectomy. Appropriately powered RCTs

There were 109 articles published in the Journal of Cardiovascular Magnetic Resonance (JCMR) in 2013, which is a 21% increase on the 90 articles published in 2012. The quality of the submissions continues to increase. The editors are delighted to report that the 2012 JCMR Impact Factor (which is published in June 2013) has risen to 5.11, up from 4.44 for 2011 (as published in June 2012), a 15% increase and taking us through the 5 threshold for the first time. The 2012 impact factor means that the JCMR papers that were published in 2010 and 2011 were cited on average 5.11 times in 2012. The impact factor undergoes natural variation according to citation rates of papers in the 2 years following publication, and is significantly influenced by highly cited papers such as official reports. However, the progress of the journal's impact over the last 5 years has been impressive. Our acceptance rate is journal. We hope that you find the open-access system increases wider reading and citation of your papers, and that you will continue to send your quality manuscripts to JCMR for publication.

Has new media made us all journalists now? What makes someone a journalist anyway? Is journalism a profession? And if so, what makes a journalist professional? Today, as traditional journalism is challenged by the ever-changing and ever-increasing media market, journalists and journalism...... researchers are constantly questioning the professionalism of journalism. Silvio Waisbord's new book provides an excellent exploration of answers to questions such as these. I was particularly curious to read Waisbord's book, having just finished my PhD thesis (Thomsen, 2013) about the professional values...... of broadcast journalists. During the writing of my PhD, I had searched in vain for a current reference book that provided a thorough review of the history, meanings and expectations of professionalism in journalism today...

Evidence-based medicine works best if the evidence is reported well. Past studies have shown reporting quality to be lacking in the field of surgery. Reporting guidelines are an important tool for authors to optimize the reporting of their research. The objective of this study was to analyse the frequency and strength of recommendation for such reporting guidelines within surgical journals. A systematic review of the 198 journals within the Journal Citation Report 2014 (surgery category) published by Thomson Reuters was undertaken. The online guide for authors for each journal was screened by two independent groups and results compared. Data regarding the presence and strength of recommendation to use reporting guidelines was extracted. 193 journals were included (as five appeared twice having changed their name). These had a median impact factor of 1.526 (range 0.047-8.327), with a median of 145 articles published per journal (range 29-659), with 34,036 articles published in total over the two-year window 2012-2013. The majority (62%) of surgical journals made no mention of reporting guidelines within their guidelines for authors. Of the 73 (38%) that did mention them, only 14% (10/73) required the use of all relevant reporting guidelines. The most frequently mentioned reporting guideline was CONSORT (46 journals). The mention of reporting guidelines within the guide for authors of surgical journals needs improvement. Authors, reviewers and editors should work to ensure that research is reported in line with the relevant reporting guidelines. Journals should consider hard-wiring adherence to them.

During the past decade, a number of journals have implemented dual-use policies in order to analyze whether the papers submitted for publication could raise concern because of the potential for misuse of their content. In this context, an analysis was performed on Latin American scientific journals to examine whether they apply formal written dual-use review policies and whether they inform their authors and reviewers about potentially sensitive issues in this area, as other international journals do. Peer-reviewed life sciences journals indexed in Latindex from Brazil, Mexico, Argentina, and Chile were analyzed. The Guide for Authors and the Instructions to Referees of 216 journals included in the Latindex catalogue (which means that they meet the best quality standards of the Latindex system) were screened for biosecurity-related information using the keywords biosecurity, biological weapons, and dual-use research of concern. Results showed that the screened publications had a total lack of dual-use review policies, even though some of them pointed out ethical behaviors to be followed related to authorship, plagiarism, simultaneous submission, research results misappropriation, ethical principles for medical research involving human subjects, guiding principles for the care and use of animals in research, research standard violations, and reviewer bias, among others.

Research in the field of cardiopulmonary disease in Brazil has been very active in recent decades. The combination of PUBMED, SCieLO, open access and online searching has provided a significant increase in the visibility of Brazilian journals. This newly acquired international visibility has in turn resulted in the appearance of more original research reports in the Brazilian scientific press. This review is intended to highlight part of this work for the benefit of the readers of "Clinics." We searched through PUBMED for noteworthy articles published in Brazilian medical journals included in the Journal of Citation Reports of the Institute of Scientific Information to better expose them to our readership. The following journals were examined: "Arquivos Brasileiros de Cardiologia," "Arquivos Brasileiros de Endocrinologia e Metabologia," "Brazilian Journal of Medical and Biological Reviews," "Jornal Brasileiro de Pneumologia," "Jornal de Pediatria," "Revista Brasileira de Cirurgia Cardiovascular," "Revista da Associação Médica Brasileira," Revista da Escola de Enfermagem U.S.P." and "São Paulo Medical Journal." These journals publish original investigations in the field of cardiopulmonary disease. The search produced 71 references, which are briefly examined.

Full Text Available Purpose. This study retrospectively analyzed cataract surgeries to examine the usefulness of Surgical Media Center (SMC (Abbott Medical Optics Inc., a new cataract surgery recording device, for training of cataract surgery. Methods. We studied five hundred cataract surgeries conducted with a phacoemulsification system connected to the SMC. After surgery, the surgical procedures were reviewed, with changes in aspiration rate, vacuum level, and phaco power displayed as graphs superimposed on the surgical video. We examined whether use of SMC is able to demonstrate the differences in technique between experienced and trainee operators, to identify inappropriate phacoemulsification techniques from analyzing the graphs, and to elucidate the cause of intraoperative complications. Results. Significant differences in the time taken to reach maximum vacuum and the speed of increase in vacuum during irrigation and aspiration were observed between experienced and trainee operators. Analysis of the graphs displayed by SMC detected inappropriate phacoemulsification techniques mostly in cases operated by trainee operators. Conclusions. Using SMC, it was possible to capture details of cataract surgery objectively. This recording device allows surgeons to review cataract surgery techniques and identify the cause of intraoperative complication and is a useful education tool for cataract surgery.

As pressure to publish increases in the academic nursing world, journal submission numbers and rejection rates are soaring. The review process is crucial to journals in publishing high quality, cutting-edge knowledge development, and to authors in preparing their papers to a high quality to enable the nursing world to benefit from developments in knowledge that affect nursing practice and patient outcomes and the development of the discipline. This paper does not intend to contribute to the debate regarding the ethics of reviewing, but rather seeks to explore notions of how the quality of the reviewing process can be enhanced to benefit authors, the reviewers, and the state of nursing knowledge. Furthermore, a call is made to editors to devise strategies for aiding reviewers to attain higher validity and reliability within the reviewing process by establishing clear standards and expectations and to ensure published work is judged against industry norms for quality. © 2013 John Wiley & Sons Ltd.

Full Text Available Background: This study analyses the accounting research articles published by South African journals. Aim and setting: A review of accounting research in internationalising journals in the South African region that publish accounting research. Methods: The characteristics of accounting articles were analysed. Five journals were analysed, including the four internationalising journals, Investment Analysts Journal, Meditari Accountancy Research, South African Journal of Business Management, and South African Journal of Economic and Management Sciences and one local journal, South African Journal of Accounting Research (SAJAR. Results: The findings of this study will be of interest to journal editors, authors who would like their research to make an impact and be cited, as well as university research administrators and government higher education policy-makers. Conclusion: The analyses show that many of the highly cited articles have been published recently, boding well for the citation statistics of these journals in future and indicating some success in their efforts to internationalise. The citations of SAJAR lag behind the citations of the internationalising journals. Each journal publishes articles that cover different subject area(s. Within accounting research, accounting education and social and environmental accounting are popular areas of research, whereas taxation; the public sector; and management accounting are not well represented among published articles during 2015–2016 in these five journals. About half of all accounting articles claim their insights will contribute to the accounting literature, with much smaller percentages claiming to contribute to management, policy-making and practice. The most prolific authors and most prominent universities to some extent follow the most popular subject areas, with a social and environmental researcher, Warren Maroun, featuring strongly, and his university, the University of the

Before starting this study, Annals of Emergency Medicine had a large and unwieldy reviewer pool that demonstrated substantial variability in quality and reliability. We hypothesize that a tiered reviewer stratification system might enable our journal editors to target the bulk of their review invitations to our better reviewers and thus improve our efficiency. In 2003, we instituted a 3-tiered hierarchic classification for our reviewers and stratified them within these categories according to predefined criteria for reviewer quality and reliability. Our approximately 50 editors then targeted the bulk of their review invitations to the top performance tier. Comparing 2009 data with 2002 (the year before the system), we found fewer late reviews (13% versus 32%) and fewer reviewers not used in a given year (28% versus 59%). More top-tier reviewer invitations led to an on-time review (48% versus 37%) in 2009 compared with 2002. Editors have found the system to be simple and easy to use. No serious problems have been identified. Implementation of a tiered system stratifying journal peer reviewers by quality and reliability was readily accomplished by Annals and has appeared to improve the efficiency of our peer review.

Between 1993 and 2010, two French journals (Aster and Didaskalia) coming from different backgrounds but belonging to the same institution used to publish papers on research in science and technology education. The merging of these journals made it necessary for them to compare the different reviewing procedures used by each. This merging occurred at a time when research is becoming increasingly international which partly determines some of the reviewing procedure choices. In order for a francophone international journal to survive, it needs to take this internationalization into account in a reasoned manner. The author of this article, as a chief editor of RDST (Recherches en Didactique des Sciences et des Technologies)—the journal resulting from the merging- taking part in this merger, analyses the social, cultural and pragmatic determinants which impacted the choices made in reviewing procedures. This paper describes how these diversity of factors leads us to drop the idea of a standard reviewing procedure which would be valid for all journals.

Full Text Available Luigi Fontana, Marco Coassin, Alfonso Iovieno, Antonio Moramarco, Luca Cimino Ophthalmology Unit, Arcispedale Santa Maria Nuova – IRCCS, Reggio Emilia, Italy Abstract: Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc., the risk of intraoperative complications may be much reduced, allowing the surgeon to handle difficult cases with greater confidence and safety. This review analyzes the methodologic approach to the patient with zonular laxity with the aim of providing useful advices to limit the risks of intraoperative and postoperative complications. From the preoperative planning, to the intraoperative management of the small pupil and phacodonesis, and to the postoperative correction of capsule phimosis and intraocular lens dislocation, a step approach to the surgical management of pseudoexfoliation patients is illustrated. Keywords: pseudoexfoliation syndrome, cataract surgery, zonular laxity, intraocular lens implant, complications

This study examined the quality of peer review in three scholarly nursing journals from the perspectives of authors and editors. Specifically, the study examined the extent to which manuscript reviews provided constructive guidance for authors to further develop their work for publication, and for editors to make informed and sound decisions on the disposition of manuscripts. Corresponding authors who had submitted manuscripts to the study journals in 2005-2007 were invited via email to complete an online survey about the quality of the peer review process; 320 authors responded. In addition, one third of the reviews of manuscripts submitted in 2005-2007 (a total of 528) were selected for rating by journal editors on level of detail, bias, and constructive tone; usefulness to authors in revising/developing the manuscript; and usefulness to the editor in making a decision. A majority (73.8%) of authors agreed that peer reviews provided constructive guidance, and 75.6% agreed that reviews provided adequate rationale for editors' decisions. New authors generally reported less satisfaction with reviews than more experienced authors. Ratings of reviews by the editors revealed some problem areas, including inconsistency, insufficient feedback to the author, reviewer bias, and disrespectful tone. Given the inexperience of many nurse authors, it is incumbent upon editors and reviewers to provide guidance and support. Manuscript reviews could be improved by increasing the consistency of numeric ratings, narrative comments, and recommendations regarding disposition of the manuscripts. Nevertheless, the results of this study reaffirm the worth of the peer review approach. Publication of research and other forms of scholarly work is critical to the development of nursing knowledge that can be used in clinical practice. Authors with a variety of backgrounds, knowledge, and skills have important work to share that can serve healthcare providers and their clients. Thus, ensuring

Biomedical journals are the main route for disseminating the results of health-related research. Despite this, their editors operate largely without formal training or certification. To our knowledge, no body of literature systematically identifying core competencies for scientific editors of biomedical journals exists. Therefore, we aimed to conduct a scoping review to determine what is known on the competency requirements for scientific editors of biomedical journals. We searched the MEDLINE®, Cochrane Library, Embase®, CINAHL, PsycINFO, and ERIC databases (from inception to November 2014) and conducted a grey literature search for research and non-research articles with competency-related statements (i.e. competencies, knowledge, skills, behaviors, and tasks) pertaining to the role of scientific editors of peer-reviewed health-related journals. We also conducted an environmental scan, searched the results of a previous environmental scan, and searched the websites of existing networks, major biomedical journal publishers, and organizations that offer resources for editors. A total of 225 full-text publications were included, 25 of which were research articles. We extracted a total of 1,566 statements possibly related to core competencies for scientific editors of biomedical journals from these publications. We then collated overlapping or duplicate statements which produced a list of 203 unique statements. Finally, we grouped these statements into seven emergent themes: (1) dealing with authors, (2) dealing with peer reviewers, (3) journal publishing, (4) journal promotion, (5) editing, (6) ethics and integrity, and (7) qualities and characteristics of editors. To our knowledge, this scoping review is the first attempt to systematically identify possible competencies of editors. Limitations are that (1) we may not have captured all aspects of a biomedical editor's work in our searches, (2) removing redundant and overlapping items may have led to the

Complementary and alternative medicine (CAM) comprises a multitude of disciplines, for example, acupuncture, ayurvedic medicine, biofeedback, herbal medicine, and homeopathic medicine. While research on CAM interventions has increased and the CAM literature has proliferated since the mid-1990s, a number of our colleagues have expressed difficulties in deciding where to publish CAM articles. In response, we created a short guide to peer-reviewed MEDLINE-indexed journals that publish CAM articles. We examined numerous English-language sources to identify titles that met our criteria, whether specific to or overlapping CAM. A few of the resources in which we found the journal titles that we included are Alternative Medicine Foundation, American Holistic Nurses Association, CINAHL/Nursing Database, Journal Citation Reports database, MEDLINE, PubMed, and Research Council for Complementary Medicine. We organized the 69 selected titles for easy use by creating 2 user-friendly tables, one listing titles in alphabetical order and one listing them in topical categories. A few examples of the topical categories are Acupuncture, CAM (general), Chinese Medicine, Herbal/Plant/Phytotherapy, Neuroscience/Psychology, Nursing/Clinical Care. Our study is the first to list general CAM journals, specialty CAM journals, and overlapping mainstream journals that are peer reviewed, in English, and indexed in MEDLINE. Our goal was to assist both authors seeking publication and mainstream journal editors who receive an overabundance of publishable articles but must recommend that authors seek publication elsewhere due to space and priority issues. Publishing in journals indexed by and included in MEDLINE (or PubMed) ensures that citations to articles will be found easily. Copyright © 2012 Lippincott Williams & Wilkins.

Two cases of adrenomyeloneuropathy (AMN) in a family and the results of their MRI study are reported. Case 1, a 24-year-old male proband, was admitted to our hospital because of gait disturbance for three years. Bilateral cataracts were pointed out at birth, which required left side lenticotomy at age four. Neurological examinations on admission revealed a marked spastic paraparesis with pathological reflexes and a mild hypesthesia in the distal part of the left leg. No abnormal findings were detected in X-ray studies on the spine and spinal cord, electromyography and nerve conduction test. Serum very long chain fatty acids (VLCFAs) levels were apparently elevated, and the serum cortisol response to ACTH was low. Case 2, a 53-year-old woman, is the mother of Case 1 having a complaint of gait disturbance since age 51. She presented a mild spastic paraparesis with localized hypesthesia in the distal part of the both legs. She also had bilateral congenital cataracts. Her serum VLCFAs analysis indicated the intermediate levels between that of AMN and the normal control. Adrenal functions were normal. Cranial MRI (TR 2,000 msec/TE 80 msec) study disclosed high signal intensity areas in bilateral internal capsules in Case 1. These findings, suggesting the pathological change of dysmyelination, seemed to be well compatible with the clinical pictures. With these clinical findings and the laboratory data, these two cases were diagnosed as AMN. In addition, association of congenital cataract with AMN in both cases was characteristic in this family, which hasn't been reported in the literature. On regarding the genetic background of these two disorders, AMN and congenital cataract, it was speculated that each gene could be closely located on the same or very adjacent locus, possibly on Xq.

A growing body of literature has identified potential problems that can compromise the quality, fairness, and integrity of journal peer review, including inadequate review, inconsistent reviewer reports, reviewer biases, and ethical transgressions by reviewers. We examine the evidence concerning these problems and discuss proposed reforms, including double-blind and open review. Regardless of the outcome of additional research or attempts at reforming the system, it is clear that editors are the linchpin of peer review, since they make decisions that have a significant impact on the process and its outcome. We consider some of the steps editors should take to promote quality, fairness and integrity in different stages of the peer review process and make some recommendations for editorial conduct and decision-making.

Aim To evaluate patient satisfaction with the cataract surgery service and identify any areas for improvement, determination of patient satisfaction with referral, out-patient consultation, pre-assessment clinic, surgery and post-operative care, also to report patients' comments relating to improvement in service provision. Methodology A retrospective study was undertaken for 150 patients underwent cataract surgery at Barrow General Hospital, UK, the survey sample was by postal questionnaires. We collected our data from the theatre lists for a period of 4 month. Results This study included 150 patients; the response rate was (72% 108 patients, Most patients were referred from their general practitioner 86.1%, 93 (86.1% patients were happy with the time interval from seeing their GP to eye clinic. In the eye out patient department many factors significantly affected the level of patient satisfaction, in general the more information provided for the patient the more the satisfaction. Conclusion Patient satisfaction is on important health outcome old understanding both the domains of satisfaction as well as their relative importance to patients is necessary to improve the overall quality of patient care. Meeting the doctor, presenting all relevant information and giving printed information are very important factors in improving the patient's satisfaction with cataract surgery.

To provide a general overview of medicolegal issues that may arise before, during, and after cataract surgery. The Department of Health and Human Services Office of Inspector General has designated ophthalmology as an auditing target, an unusual step to take for an entire specialty. Ongoing False Claims Act litigation may provide greater clarity on billing Medicare for a premium intraocular lens patient's return to the operating room and charging for an intervening exam when performing cataract surgery on both eyes. Ophthalmologists should continue to follow basic principles that help decrease medicolegal risk. These include a thorough informed consent discussion before surgery and accurate and contemporaneous documentation. When complications arise, surgeons should handle them in accordance with best practices and refer patients appropriately. Problems can arise from inattentive postoperative care, so ophthalmologists should train staff members on handling of patient calls. Implementing safety protocols for intraocular lens implantation and asking for legal advice when considering certain types of financial arrangements are also prudent. Cataract surgeons also should follow guidelines for billing noncovered services carefully.

Peer-review publication is a critical step to the translation and dissemination of research results into clinical practice guidelines, health technology assessment (HTA) and payment policies, and clinical care. The objective of this study was to examine current views of journal editors regarding: (i) The value of real-world evidence (RWE) and how it compares with other types of studies; (ii) Education and/or resources journal editors provide to their peer reviewers or perceive as needed for authors, reviewers, and editors related to RWE. Journal editors' views on the value of RWE and editorial procedures for RWE manuscripts were obtained through telephone interviews, a survey, and in-person, roundtable discussion. In total, seventy-nine journals were approached, resulting in fifteen telephone interviews, seventeen survey responses and eight roundtable participants. RWE was considered valuable by all interviewed editors (n = 15). Characteristics of high-quality RWE manuscripts included: novelty/relevance, rigorous methodology, and alignment of data to research question. Editors experience challenges finding peer reviewers; however, these challenges persist across all study designs. Journals generally do not provide guidance, assistance, or training for reviewers, including for RWE studies. Health policy/health services research (HSR) editors were more likely than specialty or general medicine editors to participate in this study, potentially indicating that HSR researchers are more comfortable/interested in RWE. Editors report favorable views of RWE studies provided studies examine important questions and are methodologically rigorous. Improving peer-review processes across all study designs, has the potential to improve the evidence base for decision making, including HTA.
Most surgical procedures involving the anterior segment of the eye disrupt the normal organization of corneal innervation. Since denervation of the cornea results in impaired epithelial wound healing, increased epithelial permeability, decreased epithelial metabolic activity, and loss of cytoskeletal structures associated with cellular adhesion, it is important to identify the factors that determine the extent of neural regeneration. Mechanisms of corneal nerve damage and studies of corneal nerve fiber loss and reinnervation after cataract and refractive surgery--epikeratophakia, cryokeratomileusis, keratomileusis in situ, photorefractive keratectomy, laser in situ keratomileusis, and phacoemulsification--are reviewed and the decrease in corneal sensitivity, as a measure of corneal destruction and corneal metabolism, after these surgical procedures is compared.
Full Text Available Peer review is a self-regulation mechanism for scientific inquiry. Institutionalized and incorporated into the structure and operation of science, it has received considerable support in the academic setting. The legitimacy of peer review is based on trust and integrity. In various ways, it allocates scarce resources such as journal space, research funding, faculty recruitment, recognition, and rewards for academic achievements. But there are growing indications that peer review has yet to fulfill its potential functions, leading to negative assessments as to whether it is effective, efficient, or reliable. Many studies have found links between potential sources of bias and judgments in peer review and expressed reservations over the fairness of the process. It is, therefore, important that the peer review process should be subjected to serious scrutiny and regular evaluation that would lead to better quality and greater fairness. This study presents a systematic review of the empirical literature on peer review of journal manuscripts, grant applications, and faculty appointments and promotions. Historical and contextual information is provided as a basis for interpreting this review. Finally, the authors discuss international recommendations for good practice in peer review and the potential and problems of peer review and bibliometrics. [Article content in Chinese

Journal clubs are an essential tool in promoting clinical evidence-based medical education to all medical and allied health professionals. Twitter represents a public, microblogging forum that can facilitate traditional journal club requirements, while also reaching a global audience, and participation for discussion with study authors and colleagues. The aim of the current study was to evaluate the current state of social media-facilitated journal clubs, specifically Twitter, as an example of continuing professional development. A systematic review of literature databases (Medline, Embase, CINAHL, Web of Science, ERIC via ProQuest) was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search of Twitter, the followers of identified journal clubs, and Symplur was also performed. Demographic and monthly tweet data were extracted from Twitter and Symplur. All manuscripts related to Twitter-based journal clubs were included. Statistical analyses were performed in MS Excel and STATA. From a total of 469 citations, 11 manuscripts were included and referred to five Twitter-based journal clubs (#ALiEMJC, #BlueJC, #ebnjc, #urojc, #meded). A Twitter-based journal club search yielded 34 potential hashtags/accounts, of which 24 were included in the final analysis. The median duration of activity was 11.75 (interquartile range [IQR] 19.9, SD 10.9) months, with 7 now inactive.

Authors, editors and reviewers alike use the biomedical literature to identify appropriate journals in which to publish, potential reviewers for papers or grants, and collaborators (or competitors) with similar interests. Traditionally, this process has either relied upon personal expertise and knowledge or upon a somewhat unsystematic and laborious process of manually searching through the literature for trends. To help with these tasks, we report three utilities that parse and summarize the...

Many scientific journals use double-blind peer review to minimize potential reviewer bias concerning publication recommendations. However, because neuroradiology is a relatively small subspecialty, this process may be limited by prior knowledge of the authors' work or associated institutions. We sought to investigate the efficacy of reviewer blinding and determine the impact that unblinding may have on manuscript acceptance. For manuscripts submitted to the American Journal of Neuroradiology ( AJNR ) from January through June 2015, reviewers completed a brief anonymous questionnaire after submitting their evaluations, assessing whether they were familiar with the research or had knowledge of the authors or institutions from which the work originated. The response rate for 1079 questionnaires was 98.8%; 12.9% of reviewers knew or suspected that they knew authors, and 15.3% knew or suspected that they knew the associated institutions. Reviewers correctly identified the authors in 90.3% of cases and correctly stated the institutions in 86.8% of cases. Unblinding resulted from self-citation in 34.1% for both authorship and institutions. The acceptance rate when reviewers knew or suspected that they knew the authors was 57/137 (41.6%) and 262/929 (28.2%) when reviewers did not. The acceptance rate when reviewers knew or suspected that they knew the institutions was 60/163 (36.8%) and 259/903 (28.7%) when they did not. The Fisher exact test showed that author ( P peer review minimizes reviewer bias, perceived knowledge of the author and institution is associated with a higher rate of manuscript acceptance. © 2017 by American Journal of Neuroradiology.

Full Text Available BACKGROUND: Editorial peer review is universally used but little studied. We examined the relationship between external reviewers' recommendations and the editorial outcome of manuscripts undergoing external peer-review at the Journal of General Internal Medicine (JGIM. METHODOLOGY/PRINCIPAL FINDINGS: We examined reviewer recommendations and editors' decisions at JGIM between 2004 and 2008. For manuscripts undergoing peer review, we calculated chance-corrected agreement among reviewers on recommendations to reject versus accept or revise. Using mixed effects logistic regression models, we estimated intra-class correlation coefficients (ICC at the reviewer and manuscript level. Finally, we examined the probability of rejection in relation to reviewer agreement and disagreement. The 2264 manuscripts sent for external review during the study period received 5881 reviews provided by 2916 reviewers; 28% of reviews recommended rejection. Chance corrected agreement (kappa statistic on rejection among reviewers was 0.11 (p<.01. In mixed effects models adjusting for study year and manuscript type, the reviewer-level ICC was 0.23 (95% confidence interval [CI], 0.19-0.29 and the manuscript-level ICC was 0.17 (95% CI, 0.12-0.22. The editors' overall rejection rate was 48%: 88% when all reviewers for a manuscript agreed on rejection (7% of manuscripts and 20% when all reviewers agreed that the manuscript should not be rejected (48% of manuscripts (p<0.01. CONCLUSIONS/SIGNIFICANCE: Reviewers at JGIM agreed on recommendations to reject vs. accept/revise at levels barely beyond chance, yet editors placed considerable weight on reviewers' recommendations. Efforts are needed to improve the reliability of the peer-review process while helping editors understand the limitations of reviewers' recommendations.

The purpose of this literature review was to ascertain the evidence for the use of reflective journaling as a tool to promote the pedagogical strategy of reflection for the purpose of learning from practice for practice in undergraduate nursing education. Concept-centric. The literature review involved structured searches of all OVID gateway databases, EBSCO host databases, and Blackwell Synergy. Qualitative and Quantitative Studies from 1992 to 2006 were included if they focused on reflective journaling in undergraduate clinical education. Due to the vast plethora of literature on reflection, keywords were utilized to focus the search. Approximately 150 abstracts were reviewed for primary sources of research. A total of nine studies met the inclusion criteria. The review subsequently divided the literature into four content themes allowing for appraisal and analysis of the findings, followed by summary and key recommendations for nursing education and research. There was evidence that educators struggle to incorporate reflective processes into education; however, the research provided rationale and support for engaging undergraduate students in the reflective process. Researchers found reasonable levels of reflection in undergraduate students' journaling and educators reported students' learning as a result of reflective journaling. Further to this, there was evidence that writing reflectively improved over time; a learned skill also dependent on a good facilitator and trust. Unfortunately, there was a paucity of research that explored the undergraduate nurses' experiences with the process of having to create written communication, with a critical reflective focus on practice. Nursing educators are correct in pursuing the teaching and learning of the reflective process in undergraduate nursing education. Nurse educators need to utilize various tools and strategies for facilitating the growth of undergraduate students into reflective practitioners. Indeed there was

Although qualitative studies have increased since the 1990s, some reports note that relatively few influential journals published them up until 2000. This study critically reviewed the characteristics of qualitative studies published in top tier medical journals since 2000. We assessed full texts of qualitative studies published between 2000 and 2004 in the Annals of Internal Medicine, BMJ, JAMA, Lancet, and New England Journal of Medicine. We found 80 qualitative studies, of which 73 (91%) were published in BMJ. Only 10 studies (13%) combined qualitative and quantitative methods. Sixty-two studies (78%) used only one method of data collection. Interviews dominated the choice of data collection. The median sample size was 36 (range: 9-383). Thirty-three studies (41%) did not specify the type of analysis used but rather described the analytic process in detail. The rest indicated the mode of data analysis, in which the most prevalent methods were the constant comparative method (23%) and the grounded theory approach (22%). Qualitative data analysis software was used by 33 studies (41%). Among influential journals of general medicine, only BMJ consistently published an average of 15 qualitative study reports between 2000 and 2004. These findings lend insight into what qualities and characteristics make a qualitative study worthy of consideration to be published in an influential journal, primarily BMJ.

A new programme of systematic reviews of randomised controlled trials (RCTs) in homeopathy will distinguish important attributes of RCT records, including: placebo controlled versus other-than-placebo (OTP) controlled; individualised versus non-individualised homeopathy; peer-reviewed (PR) versus non peer-reviewed (NPR) sources. (a) To outline the methods used to search and categorise the RCT literature; (b) to report details of the records retrieved; (c) to compare our retrieved records with those reported in two previous systematic reviews (Linde et al., 1997; Shang et al., 2005). Ten major electronic databases were searched for records published up to the end of 2011. A record was accepted for subsequent systematic review if it was a substantive report of a clinical trial of homeopathic treatment or prophylaxis in humans, randomised and controlled, and published in a PR or NPR journal. 489 records were potentially eligible: 226 were rejected as non-journal, minor or repeat publications, or lacking randomisation and/or controls and/or a 'homeopathic' intervention; 263 (164 PR, 99 NPR) were acceptable for systematic review. The 263 accepted records comprised 217 (137 PR, 80 NPR) placebo-controlled RCTs, of which 121 were included by, 66 were published after, and 30 were potentially eligible for, but not listed by, Linde or Shang. The 137 PR records of placebo-controlled RCTs comprise 41 on individualised homeopathy and 96 on non-individualised homeopathy. Our findings clarify the RCT literature in homeopathy. The 263 accepted journal papers will be the basis for our forthcoming programme of systematic reviews. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd. All rights reserved.

The PRISMA (Preferred Reporting Items of Systematic reviews and Meta-Analyses) Statement was published to help authors improve how they report systematic reviews. It is unknown how many journals mention PRISMA in their instructions to authors, or whether stronger journal language regarding use of PRISMA improves author compliance. An Internet-based investigation examined the extent to which 146 leading medical journals have incorporated the PRISMA Statement into their instructions to authors. Results were analyzed using descriptive statistics. Also, systematic reviews published in the leading anesthesiology journals and the QUOROM (QUality Of Reporting Of Meta-analyses) Statement were used to explore the hypothesis that indicating compliance with the QUOROM Statement in the manuscript is associated with improved compliance with the reporting guideline. In a sample of 146 journals publishing systematic reviews, the PRISMA Statement was referred to in the instructions to authors for 27% (40/146) of journals; more often in general and internal medicine journals (7/14; 50%) than in specialty medicine journals (33/132; 25%). In the second part of the study, 13 systematic reviews published in the leading anesthesiology journals in 2008 were included for appraisal. Mention of the QUOROM Statement in the manuscript was associated with higher compliance with the QUOROM checklist (P = 0.022). Most of the leading medical journals used ambiguous language regarding what was expected of authors. Further improvement on quality of reporting of systematic reviews may entail journals clearly informing authors of their requirements. Stronger directions, such as requiring an indication of adherence to a research quality of reporting statement in the manuscript, may improve reporting and utility of systematic reviews.

Human eyes are most sophisticated organ, with perfect and interrelated subsystems such as retina, pupil, iris, cornea, lens and optic nerve. The eye disorder such as cataract is a major health problem in the old age. Cataract is formed by clouding of lens, which is painless and developed slowly over a long period. Cataract will slowly diminish the vision leading to the blindness. At an average age of 65, it is most common and one third of the people of this age in world have cataract in one or both the eyes. A system for detection of the cataract and to test for the efficacy of the post-cataract surgery using optical images is proposed using artificial intelligence techniques. Images processing and Fuzzy K-means clustering algorithm is applied on the raw optical images to detect the features specific to three classes to be classified. Then the backpropagation algorithm (BPA) was used for the classification. In this work, we have used 140 optical image belonging to the three classes. The ANN classifier showed an average rate of 93.3% in detecting normal, cataract and post cataract optical images. The system proposed exhibited 98% sensitivity and 100% specificity, which indicates that the results are clinically significant. This system can also be used to test the efficacy of the cataract operation by testing the post-cataract surgery optical images.

To assess the quality of the content of YouTube videos for cataract surgery patient education. Hotel Dieu Hospital, Kingston, Ontario, Canada. Observational study. "Cataract surgery," "cataract surgery for patients," and "cataract surgery patient education" were used as search terms. The first two pages of search results were reviewed. Descriptive statistics such as video length and view count were obtained. Two cataract surgeons devised 14 criteria important for educating patients about the procedure. Videos were analyzed based on the presence or absence of these criteria. Videos were also assessed for whether they had a primary commercial intent. Seventy-two videos were analyzed after excluding 48 videos that were duplicate, irrelevant, or not in English. The majority of videos came from a medical professional (71%) and many depicted a real cataract surgery procedure (43%). Twenty-one percent of the videos had a primary commercial intent to promote a practice or product. Out of a total possible 14 points, the mean number of usefulness criteria satisfied was only 2.28 ± 1.80. There was no significant difference in view count between the most useful videos and other videos (p = 0.94). Videos from medical organizations such as the National Health Service were more useful (p YouTube, but most are not adequately educational. Patients may be receiving biased information from videos created with primary commercial intent. Physicians should be aware of the type of information patients may be accessing on YouTube.

To demonstrate the uses and applications of a microscope integrated intraoperative Optical Coherence Tomography in Micro Incision Cataract Surgery (MICS) and Femtosecond Laser Assisted Cataract Surgery (FLACS). Intraoperative real time imaging using the RESCAN™ 700 (Carl Zeiss Meditec, Oberkochen, Germany) was done for patients undergoing MICS as well as FLACS. The OCT videos were reviewed at each step of the procedure and the findings were noted and analyzed. Microscope Integrated Intraoperative Optical Coherence Tomography was found to be beneficial during all the critical steps of cataract surgery. We were able to qualitatively assess wound morphology in clear corneal incisions, in terms of subclinical Descemet's detachments, tears in the inner or outer wound lips, wound gaping at the end of surgery and in identifying the adequacy of stromal hydration, for both FLACS as well as MICS. It also enabled us to segregate true posterior polar cataracts from suspected cases intraoperatively. Deciding the adequate depth of trenching was made simpler with direct visualization. The final position of the intraocular lens in the capsular bag and the lack of bioadhesivity of hydrophobic acrylic lenses were also observed. Even though Microscope Integrated Intraoperative Optical Coherence Tomography is in its early stages for its application in cataract surgery, this initial assessment does show a very promising role for this technology in the future for cataract surgery both in intraoperative decision making as well as for training purposes.

Toxic anterior segment syndrome (TASS), a complication of cataract surgery, is a sterile inflammation of the anterior chamber of the eye. An outbreak of TASS was recognized at an outpatient surgical center and its affiliated hospital in December 2002. Medical records of patients who underwent cataract surgery during the outbreak were reviewed, and surgical team members who participated in the operations were interviewed. Potential causes of TASS were identified and eliminated. Feedwater from autoclave steam generators and steam condensates were analyzed by use of spectroscopy and ion chromatography. During the outbreak, 8 (38%) of 21 cataract operations were complicated by TASS, compared with 2 (0.07%) of 2,713 operations performed from January 1996 through November 2002. Results of an initial investigation suggested that cataract surgical equipment may have been contaminated by suboptimal equipment reprocessing or as a result of personnel changes. The frequency of TASS decreased (1 of 44 cataract operations) after reassignment of personnel and revision of equipment reprocessing procedures. Further investigation identified the presence of impurities (eg, sulfates, copper, zinc, nickel, and silica) in autoclave steam moisture, which was attributed to improper maintenance of the autoclave steam generator in the outpatient surgical center. When impurities in autoclave steam moisture were eliminated, no cases of TASS were observed after more than 1,000 cataract operations. Suboptimal reprocessing of cataract surgical equipment may evolve over time in busy, multidisciplinary surgical centers. Clinically significant contamination of surgical equipment may result from inappropriate maintenance of steam sterilization systems. Standardization of protocols for reprocessing of cataract surgical equipment may prevent outbreaks of TASS and may be of assistance during outbreak investigations.

Full Text Available Objective: A common disorder requiring symptom palliation in palliative and end-of-life care is cancer. Cancer pain is recognized as a global health burden. This paper sought to systematically examine the extent to which there is an adequate scientific research base on cancer pain and its reporting characteristics in the palliative care journal literature. Materials and Methods: Search conducted in MEDLINE and CINAHL sought to locate all studies published in 19 palliative/ hospice/ supportive/ end-of-life care journals from 2009 to 2010. The journals included were: American Journal of Hospice and Palliative Care, BMC Palliative Care, Current Opinion in Supportive and Palliative Care, End of Life Care Journal, European Journal of Palliative Care, Hospice Management Advisor, Indian Journal of Palliative Care, International Journal of Palliative Nursing, Internet Journal of Pain Symptom Control and Palliative Care, Journal of Pain and Palliative Care Pharmacotherapy, Journal of Palliative Care, Journal of Palliative Medicine, Journal of Social Work in End-of-life and Palliative Care, Journal of Supportive Oncology, Palliative Medicine, Palliative and Supportive Care, and Supportive Care in Cancer. Journal contents were searched to identify studies that included cancer pain in abstract. Results: During the years 2009 and 2010, of the selected 1,569 articles published in the journals reviewed, only 5.86% (92 articles were on cancer pain. Conclusion: While researchers in the field of palliative care have studied cancer pain, the total percentage for studies is still a low 5.86%. To move the field of palliative care forward so that appropriate guidelines for cancer pain management can be developed, it is critical that more research be reported upon which to base cancer pain therapy in an evidence-based palliative care model.

Full Text Available Mongolian Journal of Biological Sciences was founded in 2003 and has been continuously published, with main mission to promote the development of biology, and communication among biologists in Mongolia and around the world. MJBS is the only single peer-reviewed, regularly published English language scientifi c journal existing in the history of modern science in Mongolia. With the support and participation of biologists around the world, MJBS has since become a major scientifi c journal in Mongolia. This is evident in the quantity, quality and wide subject range of papers published in MJBS during the last ten years. Below you will fi nd a detailed explanation of my motivation for starting the new journal and some details of the journal as well. Compiling bibliographic analysis I summarize the number and type of papers published, the number and distributions of authors published with MJBS over the last ten years. During its 10 years of existence, the journal published 158 papers of different categories by 414 authors from 16 countries of the world, in 15 issues with a total of 1,140 pages. Among the research articles, most deal with ecology, behavior and conservation (64%, systematics and evolution (19%, physiology and biochemistry (13%, but only four articles (1.4% were related to genetics, molecular biology, cellular and developmental biology. The journal has the potential to change the way we share information in our discipline. Finally, I discussed the future policy and development of MJBS.

We sought to determine whether peer reviewers who attend a formal interactive training session produce better reviews. Peer reviewers were invited to attend a formal, 4-hour, highly interactive workshop on peer review. Attendees received a sample manuscript to read and review in writing in advance. The workshop included presentations on analyzing a study and the journal's expectations for a quality review, discussion of the sample manuscript's flaws and how to address them in a review, discussion of the reviews written by the attendees, and discussion of real reviews of other manuscripts illustrating key points. The performance of attendees on the basis of standard editor quality ratings (1 to 5) was assessed for the 2 years after workshop attendance. Control reviewers matched for previous review quality and volume were selected from nonattendees of the workshop. In study 1, all average reviewers received a standard written invitation. In study 2, 75 randomly selected average reviewers were personally and actively recruited with intensive follow-up by means of e-mail and telephone calls in an effort to reduce self-selection bias. In study 1, 25 reviewers volunteered for the course, were eligible for study, attended, and were compared with 25 matched control reviewers. Of attendees filling out evaluations, 19% thought it somewhat and 81% thought it very helpful. All thought it would improve their subsequent reviews, and 85% thought it would improve their review ratings. The mean change in rating after the workshop was 0.11 (95% confidence interval [CI] -0.25 to 0.48) for control reviewers and 0.10 (95% CI -0.20 to 0.39) for attendees. In study 2, of 75 reviewers intensively recruited, only 12 (41%) of those who said they would attend did. All of the participants thought the workshop would improve their performance and ratings. Test scores at the end of the workshop improved in 73% of participants compared with scores on pretests. The control reviewers' average

Social media microblogging has made major inroads in physician education and information exchange. The authors evaluated their early experience with Twitter "tweet chat" sessions as a medium to expand the reach and audience of a peer-reviewed radiology journal. The authors analyzed Twitter activity metadata tagged with the #JACR hashtag from the first 6 tweet chat sessions sponsored and promoted by JACR. The assessment included multiple metrics: radiologist versus nonradiologist session participants, individual tweets, tweets with embedded web links, common words, retweets, and impressions. We correlated Twitter metrics with temporally related journal website activity. Each session generated a mean of 444 ± 172 tweets contributed by a mean of 33 ± 14 participants (45.4% nonradiologists) and resulted in a mean of 1,163,712 ± 441,971 impressions. Per session, a mean of 19 ± 7.6 tweets contained web links, and 138 ± 35.6 tweets were retweets. Monthly journal website article views increased from 31,220 to 41,017 (+31.4%), journal website visits increased from 9,192 to 11,539 (+25.5%), and unique visitors increased from 7,368 to 8,841 (+20%). Since JACR tweet chats were initiated, mean monthly journal website visits and page views per month directly from twitter.com increased from 24 to 101 (+321%) and from 38 to 159 (+318%), respectively. Early experience with JACR tweet chats demonstrates that organizing Twitter microblogging activities around topics of general interest to their target readership bears the potential for medical journals to increase their audiences and reach.

Full Text Available The prevalence of blindness among children in different regions varies from 0.2/1000 children to over 1.5/1000 children with a global figure estimated at 0.7/1000. This means that there are an estimated 1.4 million blind children worldwide.1 The proportion of blindness in children due to cataract varies considerably between regions from 10%-30% with a global average estimated at 14%, giving 190,000 children blind from cataract. 2 While the magnitude of childhood cataracts varies from place to place, it is a priority within all blindness control programmes for children. Children who are blind have to overcome a lifetime of emotional, social and economic difficulties which affect the child, the family and society.3 Loss of vision in children influences their education, employment and social life. The numbers blind with cataract do not reflect the years of disability and lost quality of life. Childhood blindness is second only to adult cataract as a cause of blind-person years. Approximately 70 million blind-person years are caused by childhood blindness of which about 10 million blind-person years (14% is due to childhood cataract. Timely recognition and intervention can eliminate blind-years due to childhood cataract, as the condition is treatable.

Full Text Available This article describes the motivation, design, and progress of the Journal of Open Source Software (JOSS. JOSS is a free and open-access journal that publishes articles describing research software. It has the dual goals of improving the quality of the software submitted and providing a mechanism for research software developers to receive credit. While designed to work within the current merit system of science, JOSS addresses the dearth of rewards for key contributions to science made in the form of software. JOSS publishes articles that encapsulate scholarship contained in the software itself, and its rigorous peer review targets the software components: functionality, documentation, tests, continuous integration, and the license. A JOSS article contains an abstract describing the purpose and functionality of the software, references, and a link to the software archive. The article is the entry point of a JOSS submission, which encompasses the full set of software artifacts. Submission and review proceed in the open, on GitHub. Editors, reviewers, and authors work collaboratively and openly. Unlike other journals, JOSS does not reject articles requiring major revision; while not yet accepted, articles remain visible and under review until the authors make adequate changes (or withdraw, if unable to meet requirements. Once an article is accepted, JOSS gives it a digital object identifier (DOI, deposits its metadata in Crossref, and the article can begin collecting citations on indexers like Google Scholar and other services. Authors retain copyright of their JOSS article, releasing it under a Creative Commons Attribution 4.0 International License. In its first year, starting in May 2016, JOSS published 111 articles, with more than 40 additional articles under review.

Full Text Available Introduction. Cataracts cause about 50% of world blindness. There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness, like trachoma, xerophthalmia and onchocerciasis, the remedy is community-based, not hospital-based, and requires prevention rather than treatment. The prevalence of blinding cataract will only increase as people live longer, so cataract will continue to be, by far, the most important treatable cause of blindness.
In the pharmaceutical industry, bioanalysis is very dynamic and is probably one of the few fields of research covering the entire drug discovery, development and post-marketing process. Important decisions on drug safety can partially rely on bioanalytical data, which therefore can be subject to regulatory scrutiny. Bioanalytical scientists have historically contributed significant numbers of scientific manuscripts in many peer-reviewed analytical journals. All of these journals provide some high-level instructions, but they also leave sufficient flexibility for reviewers to perform independent critique and offer recommendations for each submitted manuscript. Reviewers play a pivotal role in the process of bioanalytical publication to ensure the publication of high-quality manuscripts in a timely fashion. Their efforts usually lead to improved manuscripts. However, it has to be a joint effort among authors, reviewers and editors to promote scientifically sound and ethically fair bioanalytical publications. Most of the submitted manuscripts were well written with only minor or moderate revisions required for further improvement. Nevertheless, there were small numbers of submitted manuscripts that did not meet the requirements for publications because of scientific or ethical deficiencies, which are discussed in this Letter to the Editor.

Full Text Available Then pursuing publications in international peer-reviewed journals, many legal scholars from Russia and the wider post-Soviet space face severe difficulties. This paper looks atthe reasons for these difficulties in two analytical steps. Firstly, it offers aquantitative analysis of the output of the two leading international law journals that accept submissions on doctrinal law to see how often in the two preceding years (2014 and 2015 postSoviet legal scholars with their main place of work at a university have made it into these journals. Secondly, it asks what the qualitative standards for publication in such journals are and why they are at odds specifically with the scholarly tradition in the wider post-Soviet space. The main finding of the paper is that there is a mismatch between the high goals posed by university administrators in elevating universities to some standard of excellence and the limitations presented in the field of legal scholarship. The conclusion is that a substantive re-thinking of the approach to legal scholarship is required. The introduction of ‘early legal writing’ at least at the level of master studies is one recommendation to adequately prepare a future generation of legal scholars.

Full Text Available The large amount of scientific information that is produced and available in different areas, including physical education, requires the summary of contents. Different synthesis/review methods that lead to different answers are available. The objective of this study was to analyze the policy of national physical education journals on review articles, to quantify the reviews, and to classify them as systematic and narrative reviews based on established criteria. All journals (n=13 offer the possibility to publish review articles, but do not have specific standards/methods for this type of article. The production of review articles was high (n=429, with the publication of 371 (86% narrative reviews and 58 (14% systematic reviews. A priori, narrative reviews are used for the production of knowledge by internationally renowned scientific researchers. However, the volume of production of this type of review, as diverse as the issues in physical education are, does not seem to be proportional to the number of recognized researchers. This fact can lead to lower quality of the scientific production and rejection of these articles, as observed for journals in other areas. In view of the criteria and method employed, systematic reviews seem to be more valuable in situations in which no renowned researchers wants to produce review articles, avoiding a poor outcome. This type of review is characterized by more scientific rigor, whose production follows specific steps and standards, and also seems to be more appreciated by journal editors, with these reviews sometimes even being classified as original articles.

Health professionals publishing within the field of health sciences continue to experience issues concerning appropriate authorship, which have clinical, ethical, and academic implications. This integrative review sought to explore the key issues concerning authorship from a bioethical standpoint, aiming to explore the key features of the authorship debate. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus databases of peer-reviewed research, published between 2009 and 2014, limited to English language research, with search terms developed to reflect the current issues of authorship. From among the 279 papers identified, 20 research papers met the inclusion criteria. Findings were compiled and then arranged to identify themes and relationships. The review incorporated a wide range of authorship issues encompassing equal-credited authors, honorary (guest/gift) and ghost authorship, perception/experiences of authorship, and guidelines/policies. This review suggests that the International Committee of Medical Journal Editors’ (ICMJE) recommended guidelines for authorship are not reflected in current authorship practices within the domain of health sciences in both low-and high-impact-factor journals. This devaluing of the true importance of authorship has the potential to affect the validity of authorship, diminish the real contributions of the true authors, and negatively affect patient care.

This literature review on nursing journal clubs evaluates the efficacy of the teaching strategy within the clinical setting. Peer-reviewed articles were retrieved using an online journal database. Inclusion criteria incorporated information on efficacy of the teaching strategy, evidence-based practices, and continuing education as they related to nursing journal club initiatives. The literature cited numerous benefits and proved to be in favor of nursing journal clubs. The most common benefits found were nurses remaining abreast of current research, skill development in reading and critically appraising research, and incorporation of evidenice-based practices to patient care. Due to the self-motivated and voluntary nature of this teaching strategy, a limitation commonly identified was lack of participation, and further research on this limitation often was suggested. Nursing journal clubs proved to be an effective teaching strategy; a finding that remains consistent with the medical pioneers of the movement.

Evidence-based treatments in ophthalmology are often based on the results of randomised controlled trials. Biased conclusions from randomised controlled trials may lead to inappropriate management recommendations. This systematic review investigates the prevalence of bias risk in randomised controlled trials published in high-impact ophthalmology journals and ophthalmology trials from general medical journals. Using Ovid MEDLINE, randomised controlled trials in the top 10 high-impact ophthalmology journals in 2015 were systematically identified and critically appraised for the prevalence of bias risk. Included randomised controlled trials were assessed in all domains of bias as defined by the Cochrane Collaboration. In addition, the prevalence of conflict of interest and industry sponsorship was investigated. A comparison with ophthalmology articles from high-impact general medical journals was performed. Of the 259 records that were screened from ophthalmology-specific journals, 119 trials met all inclusion criteria and were critically appraised. In total, 29.4% of domains had an unclear risk, 13.8% had a high risk and 56.8% had a low risk of bias. In comparison, ophthalmology articles from general medical journals had a lower prevalence of unclear risk (17.1%), higher prevalence of high risk (21.9%) and a higher prevalence of low risk domains (61.9%). Furthermore, 64.7% of critically appraised trials from ophthalmology-specific journals did not report any conflicts of interest, while 70.6% did not report an industry sponsor of their trial. In closing, it is essential that authors, peer reviewers and readers closely follow published risk of bias guidelines. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To assess how often stratified randomisation is used, whether analysis adjusted for all balancing variables, and whether the method of randomisation was adequately reported, and to reanalyse a previously reported trial to assess the impact of ignoring balancing factors in the analysis. Review of published trials and reanalysis of a previously reported trial. Four leading general medical journals (BMJ, Journal of the American Medical Association, Lancet, and New England Journal of Medicine) and the second Multicenter Intrapleural Sepsis Trial (MIST2). 258 trials published in 2010 in the four journals. Cluster randomised, crossover, non-randomised, single arm, and phase I or II trials were excluded, as were trials reporting secondary analyses, interim analyses, or results that had been previously published in 2010. Whether the method of randomisation was adequately reported, how often balanced randomisation was used, and whether balancing factors were adjusted for in the analysis. Reanalysis of MIST2 showed that an unadjusted analysis led to larger P values and a loss of power. The review of published trials showed that balanced randomisation was common, with 163 trials (63%) using at least one balancing variable. The most common methods of balancing were stratified permuted blocks (n=85) and minimisation (n=27). The method of randomisation was unclear in 37% of trials. Most trials that balanced on centre or prognostic factors were not adequately analysed; only 26% of trials adjusted for all balancing factors in their primary analysis. Trials that did not adjust for balancing factors in their analysis were less likely to show a statistically significant result (unadjusted 57% v adjusted 78%, P=0.02). Balancing on centre or prognostic factors is common in trials but often poorly described, and the implications of balancing are poorly understood. Trialists should adjust their primary analysis for balancing factors to obtain correct P values and confidence intervals and

Cataracts may arise in association with various major and minor disorders restricting galactose metabolism, and the risk is broadly associated with the degree of galactose intolerance. A family is described in which a girl presented at the age of 7 3/4 years with cataracts, galactosuria, and partial deficiencies of the enzymes galactokinase and galactose-1-phosphate uridyl transferase. Galactose intolerance as determined by an oral test was impaired and fluctuated with variation in activity o...

The use of topical corticosteroids following photorefractive keratectomy (PRK) is widespread. The major complications of potent corticosteroids are glaucoma and cataract formation; in order to decrease these complications, 0.1% fluorometholone administration is usually preferred after PRK. We report here a case of lens opacification which was induced by 0.1% fluorometholone administration after PRK in a period of 4 months. To our knowledge, this is the first reported case of 0.1% fluorometholone-induced cataract after PRK.

As editors, we concluded that it would be helpful to our readers to write a Year in Review article that highlights the Review, Original, and Clinical Communication articles published in 2016 in The Journal of Allergy and Clinical Immunology: In Practice. We summarized articles on the topics of asthma, rhinitis/rhinosinusitis, food allergy, anaphylaxis, drug allergy, urticarial/angioedema, eosinophilic disorders, and immunodeficiency. Within each topic, epidemiologic findings are presented, relevant aspects of prevention are described, and diagnostic and therapeutic advances are enumerated. Diagnostic tools described include history, skin tests, and in vitro tests. Treatments discussed include behavioral therapy, allergen avoidance therapy, positive and negative effects of pharmacologic therapy, and various forms of immunologic and desensitization management. We hope this review will help you, our readers, consolidate and use this extensive and practical knowledge for the benefit of your patients.

Full Text Available AIM: To compare the complication rate of femtosecond laser-assisted cataract surgery (FLACS and traditional phacoemulsification for the first 18mo of FLACS use at a private surgical center in Hawaii. METHODS: A retrospective chart review was conducted from January 2012 to June 2013. The first 273 consecutive eyes receiving FLACS and 553 eyes receiving traditional phacoemulsification were examined. All surgeries were performed at a single surgical center in Hawaii. The presence of intraoperative complications was used as the main outcome measure. Approval was obtained from the institutional review board of the University of Hawaii. RESULTS: The overall complication rate for FLACS was 1.8%, while that of the traditional procedure was 5.8% (PCONCLUSION: FLACS is comparable in safety, if not safer, than traditional cataract surgery when performed by qualified cataract surgeons on carefully selected patients.

The optimal time for surgical intervention in bilateral congenital cataract is still a matter of controversy. Herein, we evaluated clinical and functional results after bilateral congenital cataract surgery and performed subgroup analysis based on the age at the time of surgery. We retrospectively reviewed the records of 52 eyes of 26 children who underwent surgery for bilateral congenital cataract without intraocular lens implantation within the first 12 months of life; 16 eyes underwent phacoaspiration within the first 10 weeks of life (group A) and 26 eyes had cataract extraction at an age of >10 weeks (group B). We defined the primary outcome measure to be the prevalence of mild, moderate, and severe amblyopia in relationship to age-dependent visual acuity norms after a mean follow-up of 59.7 ± 43.2 months. Secondary outcome measures were interocular difference of visual acuity and the presence of strabismus, nystagmus, posterior capsule opacification, and aphakic glaucoma. The prevalence of amblyopia was not statistically different between the two age groups. Of all children, 62.5 % (A) and 61.1 % (B) developed age-dependent normal visual acuity or mild amblyopia. However, the younger cohort developed significantly less strabismus than the older cohort (P = 0.03). There was a strong relationship between cataract surgery within the first 14 weeks of life and the development of aphakic glaucoma. All children developing secondary cataract formation underwent cataract surgery in the first 20 weeks of life. Our results suggest that long-term prevalence of mild, moderate, and severe amblyopia is similar between the two cohorts of bilateral congenital cataract eyes based on the age ≤ or >10 weeks at the time of surgery. Because there is a strong relationship between postoperative complications and a young age at the time of cataract surgery, close postoperative follow-up is essential. Strabismus is less likely to develop in infants after

Physicians in ancient Persia played an important role in the development of medicine in the medieval era. One of the most influential figures of this era was Abu Ali Sina or Ibn Sina, known as Avicenna in the western world. The author of more than 200 books on medicine and philosophy, Avicenna followed and further expanded on the tradition of western philosophy and medicine introduced by Aristotle, Hippocrates and Galen. Few researchers have looked into the different medical issues in his best known work, the Canon of Medicine, particularly with regard to ophthalmology. In this analysis, Avicenna's views on and contributions to the diagnosis and treatment of cataracts in his Canon were elucidated. We first reviewed an electronic copy of the Canon and then reviewed other important sources in traditional medicine including the Kamel-al-Sanaeh, Al-Havi (Continents) and Zakhireh-kharazmshahi, available in the Avicenna Special Traditional Medicine Library of Shiraz University of Medical Sciences. We also searched Medline, Embase, Scopus, Iranmedex and Science Iranian Database (SID) with these keywords: "traditional medicine," "Avicenna," "cataract", "Canon", "history", "ophthalmology" and "eye disorders". According to the Canon, nozul-al-maa or cataract is an obstructive disease in which external moisture accumulates between the aqueous humor and the corneal membrane and prevents images from entering the eye. Avicenna classified cataracts on the basis of size, density and color. According to size, he identified two types of cataracts including complete and partial obstruction. According to the Canon, surgical intervention was necessary only for certain indications. Avicenna believed that opacity in the initial stages of cataract could be diminished by medicines and foods, and described several medicines for cataracts. He believed that surgery should be postponed until the liquid accumulation stopped, and the cataract reached its mature state. After surgery, according to

IJS launched best evidence topic reviews (BETs) in 2011, when the guidelines for conducting and reporting these reviews were published in the journal. (1) Audit the adherence of all published BETs in IJS to these guidelines. (2) Assess the reach and impact of BETs published in IJS. BETs published between 2011 and February 2014 were identified from http://www.journal-surgery.net/. Standards audited included: completeness of description of study attrition, and independent verification of searches. Other extracted data included: relevant subspecialty, duration between searches and publication, and between acceptance and publication. Each BET's number of citations (http://scholar.google.co.uk/), number of tweets (http://www.altmetric.com/) and number of Researchgate views (https://www.researchgate.net/) were recorded. Thirty-four BETs were identified: the majority, 19 (56%), relating to upper gastrointestinal surgery and none to cardiothoracic, orthopaedic or paediatric surgery. Twenty-nine BETs (82%) fully described study attrition. Twenty-one (62%) had independently verified search results. The mean times from literature searching to publication and acceptance to publication were 38.5 weeks and 13 days respectively. There were a mean 40 (range 0-89) Researchgate views/article, mean 2 (range 0-7) citations/article and mean 0.36 (range 0-2) tweets/article. Adherence to BET guidelines has been variable. Authors are encouraged to adhere to journal guidelines and reviewers and editors to enforce them. BETs have received similar citation levels to other IJS articles. Means of increasing the visibility of published BETs such as social media sharing, conference presentation and deposition of abstracts in public repositories should be explored. More work is required to encourage more submissions from other surgical subspecialties other than gastrointestinal specialties. Copyright © 2015 IJS Publishing Group Limited.

To prospectively evaluate the impact of increasing levels of social media engagement on page visits and web-link clicks for content published in the Journal of the American College of Radiology. A three-arm prospective trial was designed using a control group, a basic Twitter intervention group (using only the Journal's @JACRJournal Twitter account), and an enhanced Twitter intervention group (using the personal Twitter accounts of editorial board members and trainees). Overall, 428 articles published between June 2013 and July 2015 were randomly assigned to the three groups. Article-specific tweets for both intervention arms were sent between September 14, 2015, and October 28, 2015. Primary end points included article-specific weekly and monthly page visits on the journal's Elsevier website (Amsterdam, Netherlands). For the two intervention groups, additional end points included 7-day and 30-day Twitter link clicks. Weekly page visits for the enhanced Twitter arm (mean 18.2; 95% confidence interval [CI] 15.6-20.7) were significantly higher when compared with the weekly page visits for the control arm (mean 7.6; 95% CI 1.7-13.6). However, there was no demonstrable increase in weekly page visits (mean 9.4; 95% CI 7.4-11.5) for the basic Twitter arm compared with the control arm. No intervention effects over control, regardless of Twitter arm assignment, were demonstrated for monthly page visits. The enhanced Twitter intervention resulted in a statistically significant increase in both 7-day and 30-day Twitter link clicks compared with the basic Twitter intervention group. An organized social media strategy, with focused social media activity from editorial board members, increased engagement with content published in a peer-reviewed radiology journal.

Climate change is predicted to be one of the largest global health threats of the 21st century. Health care itself is a large contributor to carbon emissions. Determining the carbon footprint of specific health care activities such as cataract surgery allows the assessment of associated emissions and identifies opportunities for reduction. To assess the carbon footprint of a cataract pathway in a British teaching hospital. This was a component analysis study for one patient having first eye cataract surgery in the University Hospital of Wales, Cardiff. Activity data was collected from three sectors, building and energy use, travel and procurement. Published emissions factors were applied to this data to provide figures in carbon dioxide equivalents (CO2eq). The carbon footprint for one cataract operation was 181.8 kg CO2eq. On the basis that 2230 patients were treated for cataracts during 2011 in Cardiff, this has an associated carbon footprint of 405.4 tonnes CO2eq. Building and energy use was estimated to account for 36.1% of overall emissions, travel 10.1% and procurement 53.8%, with medical equipment accounting for the most emissions at 32.6%. This is the first published carbon footprint of cataract surgery and acts as a benchmark for other studies as well as identifying areas for emissions reduction. Within the procurement sector, dialogue with industry is important to reduce the overall carbon footprint. Sustainability should be considered when cataract pathways are designed as there is potential for reduction in all sectors with the possible side effects of saving costs and improving patient care.

The purpose of this study is to review samples from research on gay, lesbian, and bisexual (GLB) issues and to evaluate the suitability of this body of research to support affirmative and evidence-based practice with GLB clients. The authors systematically reviewed the sampling methodology and sample composition of GLB-related research. All original, quantitative articles focusing on GLB issues published in couple and family therapy (CFT)-related journals since 1975 were coded (n = 153). Results suggest that within the GLB literature base there is some evidence of heterocentrism as well as neglect of issues of class, race, and gender. Suggestions to improve the diversity and representativeness of samples-and, thus, clinical implications-of GLB-related research in CFT literature are provided. © 2017 American Association for Marriage and Family Therapy.

Researchers contribute to the scientific peer review system by providing reviews, and "withdraw" from it by submitting manuscripts that are subsequently reviewed. So far as we are aware, there has been no quantification of the balance of individual's contributions and withdrawals. We compared the number of reviews provided by individual researchers (i.e., their contribution) to the number required by their submissions (i.e. their withdrawals) in a large and anonymised database provided by the British Ecological Society. The database covered the Journal of Ecology, Journal of Animal Ecology, Journal of Applied Ecology, and Functional Ecology from 2003-2010. The majority of researchers (64%) did not have balanced contributions and withdrawals. Depending on assumptions, 12% to 44% contributed more than twice as much as required; 20% to 52% contributed less than half as much as required. Balance, or lack thereof, varied little in relation to the number of years a researcher had been active (reviewing or submitting). Researchers who contributed less than required did not lack the opportunity to review. Researchers who submitted more were more likely to accept invitations to review. These finding suggest overall that peer review of the four analysed journals is not in crisis, but only due to the favourable balance of over- and under-contributing researchers. These findings are limited to the four journals analysed, and therefore cannot include researcher's other peer review activities, which if included might change the proportions reported. Relatively low effort was required to assemble, check, and analyse the data. Broader analyses of individual researcher's peer review activities would contribute to greater quality, efficiency, and fairness in the peer review system.

Systematic reviews (SRs) and meta-analyses (MAs) of nursing interventions have become increasingly popular in China. This review provides the first examination of epidemiological characteristics of these SRs as well as compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses and Assessment of Multiple Systematic Reviews guidelines. The purpose of this study was to examine epidemiologic and reporting characteristics as well as the methodologic quality of SRs and MAs of nursing interventions published in Chinese journals. Four Chinese databases were searched (the Chinese Biomedicine Literature Database, Chinese Scientific Journal Full-text Database, Chinese Journal Full-text Database, and Wanfang Database) for SRs and MAs of nursing intervention from inception through June 2013. Data were extracted into Excel (Microsoft, Redmond, WA). The Assessment of Multiple Systematic Reviews and Preferred Reporting Items for Systematic Reviews and Meta-analyses checklists were used to assess methodologic quality and reporting characteristics, respectively. A total of 144 SRs were identified, most (97.2%) of which used "systematic review" or "meta-analyses" in the titles. None of the reviews had been updated. Nearly half (41%) were written by nurses, and more than half (61%) were reported in specialist journals. The most common conditions studied were endocrine, nutritional and metabolic diseases, and neoplasms. Most (70.8%) reported information about quality assessment, whereas less than half (25%) reported assessing for publication bias. None of the reviews reported a conflict of interest. Although many SRs of nursing interventions have been published in Chinese journals, the quality of these reviews is of concern. As a potential key source of information for nurses and nursing administrators, not only were many of these reviews incomplete in the information they provided, but also some results were misleading. Improving the quality of SRs of

An estimated $100 billion is lost to 'waste' in biomedical research globally, annually, much of which comes from the poor quality of published research. One area of waste involves bias in reporting research, which compromises the usability of published reports. In response, there has been an upsurge in interest and research in the scientific process of writing, editing, peer reviewing, and publishing (that is, journalology) of biomedical research. One reason for bias in reporting and the problem of unusable reports could be due to authors lacking knowledge or engaging in questionable practices while designing, conducting, or reporting their research. Another might be that the peer review process for journal publication has serious flaws, including possibly being ineffective, and having poorly trained and poorly motivated reviewers. Similarly, many journal editors have limited knowledge related to publication ethics. This can ultimately have a negative impact on the healthcare system. There have been repeated calls for better, more numerous training opportunities in writing for publication, peer review, and publishing. However, little research has taken stock of journalology training opportunities or evaluations of their effectiveness. We will conduct a systematic review to synthesize studies that evaluate the effectiveness of training programs in journalology. A comprehensive three-phase search approach will be employed to identify evaluations of training opportunities, involving: 1) forward-searching using the Scopus citation database, 2) a search of the MEDLINE In-Process and Non-Indexed Citations, MEDLINE, Embase, ERIC, and PsycINFO databases, as well as the databases of the Cochrane Library, and 3) a grey literature search. This project aims to provide evidence to help guide the journalological training of authors, peer reviewers, and editors. While there is ample evidence that many members of these groups are not getting the necessary training needed to excel

This study was performed to analyze the characteristics and trends of published research papers related to infection control in Korean nursing journals. A total of 177 studies published between 1970 and 2011 were reviewed using analysis criteria. Subject articles were selected through KoreaMed and journal database searches on the website of subject academic societies using key words related to healthcare-associated infections. Most reports were quantitative studies and the majority of them were descriptive studies. The most common subjects of research were infection control measures for pathogens, followed by disinfection and sterilization, and hand hygiene. Among them, the most descriptive studies were conducted on the knowledge, attitude, and performance of infection control. Theoretical framework, criteria for sample size and ethical consideration were rarely presented in quantitative studies. To enhance the quality of infection control studies and establish infection control studies as a nursing knowledge body, meta-analyses and systematic literature reviews as well as quantitative studies are needed. Moreover, studies employing behavioral science to identify factors influencing the level of knowledge and practice and to change infection control behaviors are also warranted. Copyright © 2014.

PurposeTo report the clinical experience of using the Tecnis PCB00 (Abbott Medical Optics, Santa Ana, CA, USA) preloaded one-piece intraocular lens (IOL) in the setting of a tertiary referral centre for paediatric cataract.MethodsA retrospective case note review of all paediatric cataract surgeries using the Tecnis PCB00 IOL, at a single UK paediatric ophthalmology department.ResultsNine eyes in seven patients received the IOL between December 2014 and January 2016. All patients underwent lens aspiration and insertion of the IOL 'in the bag.' The indications for surgery included developmental cataract (8/9) and traumatic cataract (1/9). Mean age at the time of surgery was 7 years (range 2-14). The median improvement in logMAR best-corrected visual acuity was 0.475 (range 0.250-1.500). The mean follow-up duration was 5 months (range 1-13). No operative or post-operative complications occurred as a result of using the device.ConclusionThe Tecnis PCB00 preloaded IOL appears to be a safe and effective device in treating paediatric cataract.

To examine the incidence of cataract and cataract extraction in a trial of folic acid and vitamins B6 and B12. In a randomized, double-masked, placebo-controlled trial, 5442 female health professionals aged 40 years or older with preexisting cardiovascular disease (CVD) or three or more CVD risk factors were randomly assigned to receive a combination of folic acid (2.5 mg/day), vitamin B6 (50 mg/day), and vitamin B12 (1 mg/day), or placebo. A total of 3925 of these women did not have a diagnosis of cataract at baseline and were included in this analysis. The primary endpoint was age-related cataract, defined as an incident age-related lens opacity, responsible for a reduction in best-corrected visual acuity to 20/30 or worse, based on self-report confirmed by medical record review. Extraction of incident age-related cataract was a secondary endpoint of the trial. During an average of 7.3 years of treatment and follow-up, 408 cataracts and 275 cataract extractions were documented. There were 215 cataracts in the combination treatment group and 193 in the placebo group (hazard ratio, HR, 1.10, 95% confidence interval, CI, 0.90-1.33; p = 0.36). For the secondary endpoint of cataract extraction, there were 155 in the combination treatment group and 120 in the placebo group (HR 1.28, 95% CI 1.01-1.63; p = 0.04). In this large-scale randomized trial of women at high risk of CVD, daily supplementation with a combination of folic acid, vitamin B6, and vitamin B12 had no significant effect on cataract, but may have increased the risk of cataract extraction.

The number of people coming for cataract surgery in Madagascar remains low and most ophthalmologists could do many more surgeries than currently done. Knowing why people identified with cataract do not accept surgery will help to design programs that use existing resources more effectively. The study was carried out in Sava Region of Madagascar. People with blinding (acceptance were proximity to hospital (people from Sambava district were twice as likely to present as people from more distant districts) and perceived price of transport and food (being higher for people not accepting). The actual price of surgery was not the main barrier to acceptance of surgery; instead it appears that distance to the hospital and the willingness to pay are important predictors. Strategies to improve uptake need to be revised in order to ensure that people have access to and use cataract surgical services.

The introduction of femtosecond lasers is potentially a major shift in the way we approach cataract surgery. The development of increasingly sophisticated intraocular lenses (IOLs), coupled with heightened patient expectation of high quality postsurgical visual outcomes, has generated the need for a more precise, highly reproducible and standardized method to carry out cataract operations. As femtosecond laser-assisted cataract surgery (FLACS) becomes more commonplace in surgical centers, further evaluation of the potential risks and benefits needs to be established, particularly in the medium/long term effects. Healthcare administrators will also have to weigh and balance out the financial costs of these lasers relative to the advantages they put forth. In this review, we provide an operational overview of three of five femtosecond laser platforms that are currently commercially available: the Catalys (USA), the Victus (USA), and the LDV Z8 (Switzerland).

To evaluate the feasibility of robot-assisted simulated cataract surgery. Institut de Recherche Contre les Cancers de l'Appareil Digestif, European Institute of Telesurgery, and Strasbourg University Hospital, Strasbourg, France. Experimental study. Cataract surgeries were performed on a Kitaro cataract wet-lab training system simultaneously using the Da Vinci Xi robotic surgical system and the Whitestar Signature phacoemulsification system. For each procedure, the duration and successful completion of the surgery with or without ocular complications were assessed. Procedures were successfully performed on 25 lens nuclei. The feasibility of robot-assisted simulated cataract surgery was confirmed. The robotic surgical system provided the intraocular dexterity and operative field visualization necessary to perform the main steps of the phacoemulsification procedure; that is, corneal incisions, capsulorhexis, grooving, cracking, quadrant removal, and irrigation/aspiration of the ophthalmic viscosurgical device (OVD). The intervention of a second surgeon was required for the intraocular injections of OVD, balanced salt solution, and intraocular lenses. The mean operative time was 26.44 minutes ± 5.15 (SD). All lens nuclei were removed. Inadvertent enlargement of the main corneal incision caused by the phaco handpiece was observed in 2 cases. Experimental robot-assisted cataract surgery was technically feasible using the new robotic surgical system combined with a phacoemulsification machine. Copyright © 2017 ASCRS and ESCRS.

Since ancient times a grey or white pupil in an nearly blind eye was thought to be caused by a mucous substance in front of the lens. It was called "hypochysis" or "hypochyma" in Greece and "suffusio" in Rome. Later the term "cataract" (=waterfall) was the most popular denomination. A surgical method was tried very early with usually good effect, when with a thin needle, introduced into the eye, the opaque material was removed from the pupillary area. In the middle of the 17th century more careful investigations showed that there was no membrane in front of the lens, but the lens itself was opaque. The final proof was delivered when an extraction of the lens was performed with good effect. In ancient times incurable blindness, which was called glaucoma, was thought to be located to the lens, which probably had a very important role in the seeing process. The name (of Greek orgin) is translated "green" or "blue-green", which was sometimes notified to be the color of the lens, seen through the pupil, in these cases. A period of great confusion followed when the removal of this very important part of the eye did not lead to blindness but rather an improved vision. As there were significant difficulties in identifying the specific color of the pupil the name glaucoma seemed to be very inadequate. In the beginning of the 19th century a disease entity (which is to-day called acute closed-angle glaucoma) seemed to eventually fullfill the demand of a greenlooking pupil. The most characteristic symptoms are pain and a high intraocular pressure causing a corneal edema and a change of the blackness of the pupil to hazy grey (and maybe a little green?).

To report basic epidemiological data concerning surgically treated childhood cataract in Sweden and Denmark. Data were derived from the Paediatric Cataract Register (PECARE), a binational, web-based surgical register representing Sweden and Denmark. All children operated before 8 years of age between 1 January 2007 and 31 December 2013 were included. Age-specific prevalence per 100 000 population was calculated. A total 574 operations in 213 boys (51.7%) and 199 girls (48.3%), altogether 412 children, were registered, the vast majority (n = 395/412; 95.9%) being individuals with congenital/infantile cataract. Of these 412, a total of 294 (147 boys and 147 girls) were Swedish and 118 (66 boys and 52 girls) were Danish. The age-specific prevalence of operated cataract in Sweden was 31/100 000 and in Denmark 28/100 000. In 454 of 574 eyes (79.1%), the cataract was dense. Altogether, 266 of 574 (46.3%) were operated during the first year of life, 193 during the first 12 weeks representing 33.6% of all operations. A primary intraocular lens (IOL) implantation was done in altogether 411 of 574 eyes (71,6%). In total, 210 unilateral cataract operations (210/574; 36.6%) were performed. Persistent fetal vasculature (PFV) was present in 64 of 193 (33.1%) of those with a congenital unilateral cataract. In 84 individuals (84/395; 21.3%) with congenital or infantile cataract, a coexisting disorder was found. The age-specific binational prevalence of operated congenital/infantile cataract in Sweden and Denmark is 30/100 000. About half of the operations are performed within the first year of life, one-third within the first 3 months. In our study population, a primary IOL was implanted in the majority of cases. © 2017 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Peer review is the major method used by biomedical journals for making the decision of publishing an article. This cross-sectional survey assesses views concerning the review system of biomedical journals among academics globally. A total of 28,009 biomedical academics from high-ranking universities listed by the 2009 Times Higher Education Quacquarelli Symonds (THE-QS) World University Rankings were contacted by email between March 2010 and August 2010. 1,340 completed an online survey which focused on their academic background, negative experiences and views on biomedical journal peer review and the results were compared among basic scientists, clinicians and clinician scientists. Fewer than half of the respondents agreed that the peer review systems of biomedical journals were fair (48.4%), scientific (47.5%), or transparent (25.1%). Nevertheless, 58.2% of the respondents agreed that authors should remain anonymous and 64.4% agreed that reviewers should not be disclosed. Most, (67.7%) agreed to the establishment of an appeal system. The proportion of native English-speaking respondents who agreed that the "peer review system is fair" was significantly higher than for non-native respondents (p = 0.02). Similarly, the proportion of clinicians stating that the "peer review system is fair" was significantly higher than that for basic scientists and clinician-scientists (p = 0.004). For females, (β = -0.1, p = 0.03), the frequency of encountering personal attacks in reviewers' comments (β = -0.1, p = 0.002) and the frequency of imposition of unnecessary references by reviewers (β = -0.06, p = 0.04) were independently and inversely associated with agreement that "the peer review system is fair". Academics are divided on the issue of whether the biomedical journal peer review system is fair, scientific and transparent. A majority of academics agreed with the double-blind peer review and to the establishment of an appeal system. Female academics, experience of

Methylphenidate hydrochloride (Ritalin) is the drug of choice for attention deficit hyperactivity disorder (ADHD). However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-corrected visual acuity was 6/60 in both eyes. Ocular examinations revealed intraocular pressure (IOP) of 30 mmHg under medication, dense posterior subcapsular opacity of lens, pale disc with advanced cupping, and marked constriction of visual field. Despite maximal anti-glaucomatous medication, IOP still could not be controlled. The patient then received combined cataract and glaucoma surgery. Visual acuity improved and IOP was within normal limits in both eyes postoperatively. Large dose of methylphenidate may cause cataract and glaucoma. The mechanism remains unclear. Doctors should be aware of the possible ocular side effects of methylphenidate.

For over 30 years, astronauts in Earth orbit or on missions to the moon have been exposed to space radiation comprised of high-energy protons and heavy ions and secondary particles produced in collisions with spacecraft and tissue. Large uncertainties exist in the projection of risks of late effects from space radiation such as cancer and cataracts due to the paucity [corrected] of epidemiological data. Here we present epidemiological [corrected] data linking an increased risk of cataracts for astronauts with higher lens doses (>8 mSv) of space radiation relative to other astronauts with lower lens doses (astronauts participating in NASA's Longitudinal Study of Astronaut Health (LSAH) and individual occupational radiation exposure data. These results, while preliminary because of the use of subjective scoring methods, suggest that relatively low doses of space radiation may predispose crew to [corrected] an increased incidence and early appearance of cataracts.

Full Text Available According to the World Health Organization, cataract is the leading cause of blindness and visual impairment throughout the world. However, the etiology of cataracts often remains unknown. This report describes the development of cortical cataract in a patient after Parinaud's oculoglandular syndrome caused by the fungus Sporothrix schenckii.
Full Text Available The anterior lens epithelial cells undergo a variety of degenerative and proliferative changes during cataract formation. Acid phosphatase is primarily responsible for tissue regeneration and tissue repair. The lipid hydroperoxides that are obtained by lipid peroxidation of polysaturated or unsaturated fatty acids bring about deterioration of biological membranes at cellular and tissue levels. Acid phosphatase and lipid peroxidation activities were studied on the lens epithelial cells of nuclear cataract, posterior subcapsular cataract, mature cataract, and mixed cataract. Of these, mature cataractous lens epithelium showed maximum activity for acid phosphatase (516.83 moles of p-nitrophenol released/g lens epithelium and maximum levels of lipid peroxidation (86.29 O.D./min/g lens epithelium. In contrast, mixed cataractous lens epithelium showed minimum activity of acid phosphatase (222.61 moles of p-nitrophenol released/g lens epithelium and minimum levels of lipid peroxidation (54.23 O.D./min/g lens epithelium. From our study, we correlated the maximum activity of acid phosphatase in mature cataractous lens epithelium with the increased areas of superimposed cells associated with the formation of mature cataract. Likewise, the maximum levels of lipid peroxidation in mature cataractous lens epithelium was correlated with increased permeability of the plasma membrane. Conversely, the minimum levels of lipid peroxidation in mixed cataractous lens epithelium makes us presume that factors other than lipid peroxidation may also account for the formation of mixed type of cataract.

Microwaves most commonly cause anterior and/or posterior subcapsular lenticular opacities in experimental animals and, as shown in epidemiologic studies and case reports, in human subjects. The formation of cataracts seems to be related directly to the power of the microwave and the duration of exposure. The mechanism of cataractogenesis includes deformation of heat-labile enzymes, such as glutathione peroxide, that ordinarily protect lens cell proteins and membrane lipids from oxidative damage. Oxidation of protein sulfhydryl groups and the formation of high-molecular-weight aggregates cause local variations in the orderly structure of the lens cells. An alternative mechanism is thermoelastic expansion through which pressure waves in the aqueous humor cause direct physical damage to the lens cells. Cataracts induced by ionizing radiation (e.g., X-rays and gamma rays) usually are observed in the posterior region of the lens, often in the form of a posterior subcapsular cataract. Increasing the dose of ionizing radiation causes increasing opacification of the lens, which appears after a decreasing latency period. Like cataract formation by microwaves, cataractogenesis induced by ionizing radiation is associated with damage to the lens cell membrane. Another possible mechanism is damage to lens cell DNA, with decreases in the production of protective enzymes and in sulfur-sulfur bond formation, and with altered protein concentrations. Until further definitive conclusions about the mechanisms of microwaves and ionizing radiation induced cataracts are reached, and alternative protective measures are found, one can only recommend mechanical shielding from these radiations to minimize the possibility of development of radiation-induced cataracts. 74 references

Full Text Available Cataract is one of the most common diseases, especially in the elderly. Despite the fact that the share of elderly people in economically developed countries is higher than in developing countries, the incidence of cataract in people over 50 years in Western countries is 15% and it is about 40% in developing countries. The reasons are unbalanced nutrition, lack of specialized ophthalmic care at the initial stages of the disease, the impact of adverse environmental conditions, etc. Surgical treatment is the only curative method. However, there are not always enough indications for this treatment on the one hand, and it is not always possible due to patient’s unfavorable physical status, on the other hand. The supportive anti-cataract therapy should be provided with the dynamic follow-up in such cases. The pharmaceutical industry offers anti-cataract drugs with a different composition and properties, they are based on the mechanisms of the onset and development of the disease. “Oxidative stress” is one of the main factors, which can be the cause of both nuclear and cortical cataracts. There are scattering zones in the mature nucleus of the lens, an increase in extracellular spaces between corrugated membrane protein-like deposits in case of cataract. It is generally believed that the basis of these deposits are denatured, initially water-soluble proteins, which turn into opaque substances due to the action of quinoids products formed through the disturbed metabolism of aromatic aminoacids (tryptophan, tyrosine, etc.. Based on this theory, an anti-cataract substance — pirenoxine was developed. It inhibits the action of quinoids and prevents the formation of the len’s opacities and the cataracts progression.

JOSS is a free and open-access journal that publishes articles describing research software across all disciplines. It has the dual goals of improving the quality of the software submitted and providing a mechanism for research software developers to receive credit. While designed to work within the current merit system of science, JOSS addresses the dearth of rewards for key contributions to science made in the form of software. JOSS publishes articles that encapsulate scholarship contained in the software itself, and its rigorous peer review targets the software components: functionality, documentation, tests, continuous integration, and the license. A JOSS article contains an abstract describing the purpose and functionality of the software, references, and a link to the software archive. JOSS published more than 100 articles in its first year, many from the scientific python ecosystem (including a number of articles related to astronomy and astrophysics). JOSS is a sponsored project of the nonprofit organization NumFOCUS and is an affiliate of the Open Source Initiative.In this presentation, I'll describes the motivation, design, and progress of the Journal of Open Source Software (JOSS) and how it compares to other avenues for publishing research software in astronomy.

The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited articles may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997 to 2007. We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997 to 2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164 377 articles in 222 cardiovascular journals from 1997 to 2007. From 1997 to 2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2%, respectively. Of all the articles, 75 550 (46.0%) were poorly cited, of which 25 650 (15.6% overall) had no citations. From 1997 to 2007, the proportion of poorly cited articles declined slightly (52.1%-46.2%, trend Pjournal level, 44% of cardiovascular journals had more than three-fourths of the journal's content poorly cited at 5 years. Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature and the number of poorly cited articles both increased substantially from 1997 to 2007. The high proportion of poorly cited articles and journals suggests inefficiencies in the cardiovascular research enterprise. © 2015 American Heart Association, Inc.

An up-to-date systematic review is important for researchers to decide whether to embark on new research or continue supporting ongoing studies. The aim of this study is to examine the time taken between the last search, submission, acceptance and publication dates of systematic reviews published in nursing journals. Nursing journals indexed in Journal Citation Reports were first identified. Thereafter, systematic reviews published in these journals in 2014 were extracted from three databases. The quality of the systematic reviews were evaluated by the AMSTAR. The last search, submission, acceptance, online publication, full publication dates and other characteristics of the systematic reviews were recorded. The time taken between the five dates was then computed. Descriptive statistics were used to summarize the time differences; non-parametric statistics were used to examine the association between the time taken from the last search and full publication alongside other potential factors, including the funding support, submission during holiday periods, number of records retrieved from database, inclusion of meta-analysis, and quality of the review. A total of 107 nursing journals were included in this study, from which 1070 articles were identified through the database search. After screening for eligibility, 202 systematic reviews were included in the analysis. The quality of these reviews was low with the median score of 3 out of 11. A total of 172 (85.1%), 72 (35.6%), 153 (75.7%) and 149 (73.8%) systematic reviews provided their last search, submission, acceptance and online published dates respectively. The median numbers of days taken from the last search to acceptance and to full publication were, respectively, 393 (IQR: 212-609) and 669 (427-915) whereas that from submission to full publication was 365 (243-486). Moreover, the median number of days from the last search to submission and from submission to online publication were 167.5 (53.5-427) and 153

Competencies is an important concept used for assessing health professionals' capability to perform their role. By means of a literature review of Japanese professional journals this paper will investigate the competencies concept, particularly with relation to disaster nursing. The literature research was conducted using the database ichu-shi (ver. 4). All literature is written and published in Japanese and was published between 2001 and 2008. Due to an unfamiliarity of the term 'competencies' in Japanese, the key words were sought while deconstructing the meaning and concepts of 'competencies' into terms more recognisable in the Japanese context. Twelve key words: disaster, capability, education, practice, licensure, ability, function, prevention, response, planning, emergency, and disaster nursing were chosen as being most likely to find literature relevant to the English Language concept of competencies. The searched articles were then written into the disaster nursing competencies review worksheet for analysis. One hundred and twenty articles were found by searching a combination of these key words. Of these articles, those that were not in the context of disaster nursing were eliminated. As a result, 43 articles were chosen as being suitable for analysis of the context. These articles are classified into four themes. These theme groups indicated a foundation for competencies in disaster nursing. The definition of competencies in Japanese nursing journals was quite varied and cannot be easily defined as common disaster nursing competencies. Given the variety of areas and the distinct phases in disaster nursing, as well as the 'what for' and 'who governs', disaster nursing competencies will need its own discussion in order to establish the common competencies internationally.

Materials and Methods: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Statistical Methods: Independent sample t-test, Fisher′s exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA version 12. Results: 215/257 (83.7% patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months. Congenital cataract was present in 107 patients (58.2% and developmental cataract in 77 patients (41.8%. The mean age at surgery was 55.2 months (range: 1-168 months. Out of 430 eyes, 269 (62.6% had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months. Pre-operatively, 102 patients (47.3% had visual acuity 6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3% and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%. The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5 and total cataract (OR: 4.8; 95% CI, 1.3-17. Conclusion: Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age.

In order to clarify the role of tryptophan in the patogenesis of senile cataract, we have studied the serum total and free levels of tryptophan in cataract patients as compared with age and sex-matched controls, and the urinary excretion of 10 metabolites after oral load of the amino acid. This excretion increases in the cataract group both as total per cent and as kynurenine. No difference has been found in the free and total serum tryptophan between normal subjects and cataract patients. A possible role of the kynurenines in the pathogenesis of senile cataract is suggested.

METHODS:Searching literature which were published by March 2015 and which were the random control test(RCTon the preventive effect of NSAIDs on CME after the cataract surgery in PubMed, EMbase, Cochrane Library, MEDLINE, CNKI, Wanfang Data, Chongqing Weipu and Chinese biomedical literature database and through Internet with computer. Meanwhile, relevant articles, journals, conference papers and their reference were manually retrieved. According to inclusion and exclusion criteria,the study objects were limited.Revman5.0 software provided by the Cochrane Collaboration was used to analysis the incidence of CME after cataract surgeries.RESULTS:A total of 7 RCT were included in the study(1422 cases, 712 cases in the trial group, 710 cases in the control group. Using NSAIDs before and after cataract surgeries could significantly reduce the post-operative incidence of CME(OR=0.31, 95%CI:0.18～0.52, PCONCLUSION:Using NSAIDs before and after cataract surgeries can significantly reduce the incidence of postoperative CME. Due to the small sample size and the medium methodological quality, the conclusion is not powerful enough. More high-quality RCTs with larger sample size are needed to make the evaluation more objective, accurate and comprehensive.

Full Text Available Delays in peer reviewed publication may have consequences for both assessment of scientific prowess in academics as well as communication of important information to the knowledge receptor community. We present an analysis on the perspectives of authors publishing in conservation biology journals regarding their opinions on the importance of speed in peer-review as well as how to improve review times. Authors were invited to take part in an online questionnaire, of which the data was subjected to both qualitative (open coding, categorizing and quantitative analyses (generalized linear models. We received 637 responses to a total of 6,547 e-mail invitations sent. Peer-review speed was generally perceived as slow, with authors experiencing a typical turnaround time of 14 weeks while their perceived optimal review time is six weeks. Male and younger respondents seem to have higher expectations of review speed than females and older respondents. Majority of participants attributed lengthy review times to the 'stress' on the peer-review system (i.e., reviewer and editor fatigue, while editor persistence and journal prestige were believed to speed up the review process. Negative consequences of lengthy review times appear to be greater for early career researchers and can also have impact on author morale (e.g. motivation or frustration. Competition among colleagues were also of concern to respondents. Incentivizing peer review was among the top suggested alterations to the system along with training graduate students in peer review, increased editorial persistence, and changes to the norms of peer-review such as opening the peer-review process to the public. It is clear that authors surveyed in this study view the peer-review system as under stress and we encourage scientists and publishers to push the envelope for new peer review models.

To develop a method to define a multi-stakeholder perspective on health-service quality that enables the expression of differences in systematically identified stakeholders' perspectives, and to pilot the approach for cataract care. Mixed-method study between 2014 and 2015. Cataract care in the Netherlands. Stakeholder representatives. We first identified and classified stakeholders using stakeholder theory. Participants established a multi-stakeholder perspective on quality of cataract care using concept mapping, this yielded a cluster map based on multivariate statistical analyses. Consensus-based quality dimensions were subsequently defined in a plenary stakeholder session. Stakeholders and multi-stakeholder perspective on health-service quality. Our analysis identified seven definitive stakeholders, as follows: the Dutch Ophthalmology Society, ophthalmologists, general practitioners, optometrists, health insurers, hospitals and private clinics. Patients, as dependent stakeholders, were considered to lack power by other stakeholders; hence, they were not classified as definitive stakeholders. Overall, 18 stakeholders representing ophthalmologists, general practitioners, optometrists, health insurers, hospitals, private clinics, patients, patient federations and the Dutch Healthcare Institute sorted 125 systematically collected indicators into the seven following clusters: patient centeredness and accessibility, interpersonal conduct and expectations, experienced outcome, clinical outcome, process and structure, medical technical acting and safety. Importance scores from stakeholders directly involved in the cataract service delivery process correlated strongly, as did scores from stakeholders not directly involved in this process. Using a case study on cataract care, the proposed methods enable different views among stakeholders concerning quality dimensions to be systematically revealed, and the stakeholders jointly agreed on these dimensions.

If a factor could be identified which delayed the onset of cataract by 10 years, the number of annual cataract operations worldwide has been estimated to decrease by 45%. A case-control study compared alcohol consumption in 78 patients attending for routine cataract surgery in South East London with data from a large population-based survey. Male cataract patients had a significantly greater risk of being harmful drinkers (odds ratio = 8, p = 0.007) than the controls. The harmful male drinkers were significantly younger than the non-drinkers with cataract (mean difference 15 years, p < 0.007). Female cataract patients were not more likely to be excessive drinkers than controls. The female drinkers with cataract were of a similar age to the non-drinking female patients with cataract. Haematological and biochemical indices of alcohol toxicity indicated five patients who were likely to be harmful drinkers, but who had denied this on direct questioning. Seven (26%) of the male patients had a low serum 25 hydroxycholecalciferol although the levels were normal in the female patients. These results support the view that excess alcohol consumption is related to cataract formation and suggest that alcohol causes premature cataract formation in male, but not female patients. Alcohol consumption is amenable to intervention and suggests that such intervention could have a significant impact on the need for cataract surgery.

Complete, accurate reporting of systematic reviews facilitates assessment of how well reviews have been conducted. The primary objective of this study was to examine compliance of systematic reviews in veterinary journals with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines for literature search reporting and to examine the completeness, bias, and reproducibility of the searches in these reviews from what was reported. The second objective was to examine reporting of the credentials and contributions of those involved in the search process. A sample of systematic reviews or meta-analyses published in veterinary journals between 2011 and 2015 was obtained by searching PubMed. Reporting in the full text of each review was checked against certain PRISMA checklist items. Over one-third of reviews (37%) did not search the CAB Abstracts database, and 9% of reviews searched only 1 database. Over two-thirds of reviews (65%) did not report any search for grey literature or stated that they excluded grey literature. The majority of reviews (95%) did not report a reproducible search strategy. Most reviews had significant deficiencies in reporting the search process that raise questions about how these searches were conducted and ultimately cast serious doubts on the validity and reliability of reviews based on a potentially biased and incomplete body of literature. These deficiencies also highlight the need for veterinary journal editors and publishers to be more rigorous in requiring adherence to PRISMA guidelines and to encourage veterinary researchers to include librarians or information specialists on systematic review teams to improve the quality and reporting of searches.

The KAMRA™ small aperture inlay was the first such inlay to receive Conformité Européenne (CE marking in 2005. It has been shown to improve uncorrected near and intermediate visual acuity without adversely affecting uncorrected distance visual acuity. Due to the age of presbyopic patients, they may eventually develop cataracts. In two such cases, we found that cataract surgery with the KAMRA implant left in place was not technically more difficult, and that the surgical procedure could be improved by additional ocular rotations to improve visualization. Biometry readings were reliable, and it appeared that the SRK/T formula was accurate for calculation of intraocular lens power. Cataract surgery with the KAMRA implant left in situ is a viable option for patients. Keywords: cataract surgery, KAMRA, corneal inlay, AcuTarget, presbyopia

While it is a standard practice to request for an ocular ultrasound scan in patients with traumatic cataracts when the fundus cannot be seen, the rationale is to determine the possible cause of visual loss and give the patient an idea of visual prognosis before surgery.

Purpose: To determine prospectively the cataract-free interval (latency time) after total body irradiation (TBI) and bone marrow transplantation (BMT) and to assess accurately the final severity of the cataract. Methods and Materials: Ninety-three of the patients who received TBI as a part of their conditioning regimen for BMT between 1982 and 1995 were followed with respect to cataract formation. Included were only patients who had a follow-up period of at least 23 months. TBI was applied in one fraction of 8 Gy or two fractions of 5 or 6 Gy. Cataract-free period was assessed and in 56 patients, who could be followed until stabilization of the cataract had occurred, final severity of the cataract was determined using a classification system. With respect to final severity, two groups were analyzed: subclinical low-grade cataract and high-grade cataract. Cataract-free period and final severity were determined with respect to type of transplantation, TBI dose, and posttransplant variables such as graft versus host disease (GVHD) and steroid treatment. Results: Cataract incidence of the analyzed patients was 89%. Median time to develop a cataract was 58 months for autologous transplanted patients. For allogeneic transplanted patients treated or not treated with steroids, median times were 33 and 46 months, respectively. Final severity was not significantly different for autologous or allogeneic patients. In allogeneic patients, however, final severity was significantly different for patients who had or had not been treated with steroids for GVHD: 93% versus 35% high-grade cataract, respectively. Final severity was also different for patients receiving 1 x 8 or 2 x 5 Gy TBI, from patients receiving 2 x 6 Gy as conditioning therapy: 33% versus 79% high-grade cataract, respectively. The group of patients receiving 2 x 6 Gy comprised, however, more patients with steroid treatment for GVHD. So the high percentage of high-grade cataract in the 2 x 6 Gy group might also

To describe current cataract surgery practices within the United States Veterans Health Administration (VHA). Veterans Health Administration hospitals in the U.S. Retrospective data analysis. An initial e-mail containing a link to an anonymous 32-question survey of cataract surgery practices was sent to participants in May 2016. Two reminder e-mails were sent to nonresponders 1 week and 2 weeks after the initial survey was sent; the remaining nonresponders were called twice over a 2-week period. The data were analyzed using descriptive statistics. The response rate was 75% (67/89). Cataract surgeons routinely ordered preoperative testing in 29 (45%) of 65 sections and preoperative consultations in 26 (39%) of 66 sections. In 22 (33%) of 66 sections, cataract surgeons administered intracameral antibiotics. In 61 (92%) of 66 sections, cataract surgeons used toric intraocular lenses (IOLs). In 20 (30%) of 66 sections, cataract surgeons used multifocal IOLs. Cataract surgeons in 6 (9%) of 66 sections performed femtosecond laser-assisted cataract surgery. In 6 (9%) of 66 sections, cataract surgeons performed immediate sequential bilateral cataract surgery. Forty-nine (74%) ophthalmology chiefs reported a high level of satisfaction with Veterans Affairs ophthalmology. The survey results indicate that in cataract surgery in the VHA, routine preoperative testing is commonly performed and emerging practices, such as femtosecond laser-assisted cataract surgery and immediate sequential bilateral cataract surgery, have limited roles. The results of this survey could benchmark future trends in U.S. cataract surgery practices, especially in teaching hospital settings. Copyright © 2017 ASCRS and ESCRS. Published by Elsevier Inc.

Retrospective 5-year study based on general and ophthalmic history records, and including 268 eyes (174 patients), aged 50 years and over. Ophthalmological examination involved visual acuity, measuring of intraocular pressure, slit lamp examination and indirect ophthalmoscopy. Type of surgical treatment was tailored for each patient (extra capsular cataract extraction, phaco-emulsiphication). Preoperative slit lamp examination showed phacodonesis in 17.91% (47), iridodonesis in 2.98% (8), pigment dispersion in 6.72% (18), lens subluxation in 4.85% (13) on the total. Extra capsular cataract extraction was performed in 36.94% (99) and phaco-emulsiphication in the others. Analysis of intra operative complications showed: posterior capsular rupture 17.91% (48), zonular dialysis or break 5.97% (16), lens subluxation 1.86% (5), intraocular bleeding 2.98% (8), vitreous loss 13.80% (37). Postoperative complications include: anterior chamber reaction 45.90% (123), intraocular lens tilt 15.67% (42), endothelial decompensation 21.64% (58), subluxation/luxation IOL 3.73% (10), secondary cataract 21.46% (58), pigment dispersion 37.68% (101), increased IOP 13.80% (37), residual lens matter 13.80% (37), hyphema 3.73% (10), posterior synechiae 6.72% (18), iris prolapsus 2.73% (8). Cataract surgery in PES will frequently encounter small pupils, shallow anterior chambers, posterior adhesions, weak zonular support, partial subluxation or complete dislocation of lens. Authors presented the best possible approach on PES and surgical methods for patients with cataract with special accent of possible surgical complications.

An 87-year-old woman presented 11 months after routine phacoemulsification cataract extraction and posterior chamber intraocular lens implantation in her left eye complaining of the abrupt onset of redness and decreased vision in that eye. Examination revealed a mild anterior chamber reaction and significant corneal edema. The eye was minimally responsive to topical steroid therapy, and initial serial slitlamp examinations with gonioscopy were unrevealing. After multiple head-positioning maneuvers were performed, a retained nuclear fragment was uncovered. The nuclear fragment was aspirated and liquefied by the phacoemulsification device in the anterior chamber. A retained nuclear fragment with an intact posterior capsule is a recognized cause of inflammation in the immediate postoperative presentation. Delayed presentation of symptoms is rare and presumably secondary to sequestration of the fragment behind the iris. We present a case and a review of the literature regarding sequestered retained nuclear fragments following what is initially thought to be uneventful cataract extraction. No author has a financial or proprietary interest in any material or method mentioned. Copyright © 2014 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

We apply a novel mistake index to assess trends in the proportion of corrections published between 1993 and 2014 in Nature, Science and PNAS. The index revealed a progressive increase in the proportion of corrections published in these three high-quality journals. The index appears to be independent of the journal impact factor or the number of items published, as suggested by a comparative analyses among 16 top scientific journals of different impact factors and disciplines. A more detailed analysis suggests that the trend in the time-to-correction increased significantly over time and also differed among journals (Nature 233 days; Science 136 days; PNAS 232 days). A detailed review of 1,428 errors showed that 60% of corrections were related to figures, authors, references or results. According to the three categories established, 34.7% of the corrections were considered mild, 47.7% moderate and 17.6% severe, also differing among journals. Errors occurring during the printing process were responsible for 5% of corrections in Nature, 3% in Science and 18% in PNAS. The measurement of the temporal trends in the quality of scientific manuscripts can assist editors and reviewers in identifying the most common mistakes, increasing the rigor of peer-review and improving the quality of published scientific manuscripts.

To evaluate whether quality of peer review and reviewer recommendation differ based on reviewer subspecialty in obstetrics and gynecology and to determine the role of experience on reviewer recommendation. We performed a retrospective cohort study of reviews submitted to Obstetrics & Gynecology between January 2010 and December 2014. Subspecialties were determined based on classification terms selected by each reviewer and included all major obstetrics and gynecology subspecialties, general obstetrics and gynecology, and nonobstetrics and gynecology categories. Review quality (graded on a 5-point Likert scale by the journal's editors) and reviewer recommendation of "reject" were compared across subspecialties using χ, analysis of variance, and multivariate logistic regression. There were 20,027 reviews from 1,889 individual reviewers. Reviewers with family planning subspecialty provided higher-quality peer reviews compared with reviewers with gynecology only, reproductive endocrinology and infertility, gynecologic oncology, and general obstetrics and gynecology specialties (3.61±0.75 compared with 3.44±0.78, 3.42±0.72, 3.35±0.75, and 3.32±0.81, respectively, Pobstetrics and gynecology subspecialty. Obstetrics and gynecology subspecialty and reviewer experience have implications for manuscript rejection recommendation. Reviewer assignment is pivotal to maintaining a rigorous manuscript selection process.

The aim of this study was to assess adherence to the Consolidated Standards of Reporting Trials (CONSORT) for Abstracts by five high-impact general medical journals and to assess whether the quality of reporting was homogeneous across these journals. This is a descriptive, cross-sectional study. Randomised controlled trial (RCT) abstracts in five high-impact general medical journals. We used up to 100 RCT abstracts published between 2011 and 2014 from each of the following journals: The New England Journal of Medicine (NEJM), the Annals of Internal Medicine (Annals IM), The Lancet, the British Medical Journal (The BMJ) and the Journal of the American Medical Association (JAMA). The primary outcome was per cent overall adherence to the 19-item CONSORT for Abstracts checklist. Secondary outcomes included per cent adherence in checklist subcategories and assessing homogeneity of reporting quality across the individual journals. Search results yielded 466 abstracts, 3 of which were later excluded as they were not RCTs. Analysis was performed on 463 abstracts (97 from NEJM, 66 from Annals IM, 100 from The Lancet, 100 from The BMJ, 100 from JAMA). Analysis of all scored items showed an overall adherence of 67% (95% CI 66% to 68%) to the CONSORT for Abstracts checklist. The Lancet had the highest overall adherence rate (78%; 95% CI 76% to 80%), whereas NEJM had the lowest (55%; 95% CI 53% to 57%). Adherence rates to 8 of the checklist items differed by >25% between journals. Among the five highest impact general medical journals, there is variable and incomplete adherence to the CONSORT for Abstracts reporting checklist of randomised trials, with substantial differences between individual journals. Lack of adherence to the CONSORT for Abstracts reporting checklist by high-impact medical journals impedes critical appraisal of important studies. We recommend diligent assessment of adherence to reporting guidelines by authors, reviewers and editors to promote transparency

To assess the adequacy of reporting of non-inferiority trials alongside the consistency and utility of current recommended analyses and guidelines. Review of randomised clinical trials that used a non-inferiority design published between January 2010 and May 2015 in medical journals that had an impact factor >10 (JAMA Internal Medicine, Archives Internal Medicine, PLOS Medicine, Annals of Internal Medicine, BMJ, JAMA, Lancet and New England Journal of Medicine). Ovid (MEDLINE). We searched for non-inferiority trials and assessed the following: choice of non-inferiority margin and justification of margin; power and significance level for sample size; patient population used and how this was defined; any missing data methods used and assumptions declared and any sensitivity analyses used. A total of 168 trial publications were included. Most trials concluded non-inferiority (132; 79%). The non-inferiority margin was reported for 98% (164), but less than half reported any justification for the margin (77; 46%). While most chose two different analyses (91; 54%) the most common being intention-to-treat (ITT) or modified ITT and per-protocol, a large number of articles only chose to conduct and report one analysis (65; 39%), most commonly the ITT analysis. There was lack of clarity or inconsistency between the type I error rate and corresponding CIs for 73 (43%) articles. Missing data were rarely considered with (99; 59%) not declaring whether imputation techniques were used. Reporting and conduct of non-inferiority trials is inconsistent and does not follow the recommendations in available statistical guidelines, which are not wholly consistent themselves. Authors should clearly describe the methods used and provide clear descriptions of and justifications for their design and primary analysis. Failure to do this risks misleading conclusions being drawn, with consequent effects on clinical practice. Published by the BMJ Publishing Group Limited. For permission to use
Full Text Available Objectives: Biased negative studies not only reflect poor research effort but also have an impact on ′patient care′ as they prevent further research with similar objectives, leading to potential research areas remaining unexplored. Hence, published ′negative studies′ should be methodologically strong. All parameters that may help a reader to judge validity of results and conclusions should be reported in published negative studies. There is a paucity of data on reporting of statistical and methodological parameters in negative studies published in Indian Medical Journals. The present systematic review was designed with an aim to critically evaluate negative studies published in prominent Indian Medical Journals for reporting of statistical and methodological parameters. Design: Systematic review. Materials and Methods: All negative studies published in 15 Science Citation Indexed (SCI medical journals published from India were included in present study. Investigators involved in the study evaluated all negative studies for the reporting of various parameters. Primary endpoints were reporting of "power" and "confidence interval." Results: Power was reported in 11.8% studies. Confidence interval was reported in 15.7% studies. Majority of parameters like sample size calculation (13.2%, type of sampling method (50.8%, name of statistical tests (49.1%, adjustment of multiple endpoints (1%, post hoc power calculation (2.1% were reported poorly. Frequency of reporting was more in clinical trials as compared to other study designs and in journals having impact factor more than 1 as compared to journals having impact factor less than 1. Conclusion: Negative studies published in prominent Indian medical journals do not report statistical and methodological parameters adequately and this may create problems in the critical appraisal of findings reported in these journals by its readers.

Full Text Available Abstract Background Poor recruitment and retention of participants in randomised controlled trials (RCTs is problematic but common. Clear and detailed reporting of participant flow is essential to assess the generalisability and comparability of RCTs. Despite improved reporting since the implementation of the CONSORT statement, important problems remain. This paper aims: (i to update and extend previous reviews evaluating reporting of participant recruitment and retention in RCTs; (ii to quantify the level of participation throughout RCTs. Methods We reviewed all reports of RCTs of health care interventions and/or processes with individual randomisation, published July–December 2004 in six major journals. Short, secondary or interim reports, and Phase I/II trials were excluded. Data recorded were: general RCT details; inclusion of flow diagram; participant flow throughout trial; reasons for non-participation/withdrawal; target sample sizes. Results 133 reports were reviewed. Overall, 79% included a flow diagram, but over a third were incomplete. The majority reported the flow of participants at each stage of the trial after randomisation. However, 40% failed to report the numbers assessed for eligibility. Percentages of participants retained at each stage were high: for example, 90% of eligible individuals were randomised, and 93% of those randomised were outcome assessed. On average, trials met their sample size targets. However, there were some substantial shortfalls: for example 21% of trials reporting a sample size calculation failed to achieve adequate numbers at randomisation, and 48% at outcome assessment. Reporting of losses to follow up was variable and difficult to interpret. Conclusion The majority of RCTs reported the flow of participants well after randomisation, although only two-thirds included a complete flow chart and there was great variability over the definition of "lost to follow up". Reporting of participant eligibility

Supplementation of cataract patients with multifocal intraocular lenses involves an additional financial investment when compared to the corresponding monofocal supplementation, which usually is not funded by German health care insurers. In the context of recent resource allocation discussions, however, the cost effectiveness of multifocal cataract surgery could become an important rationale. Therefore an evidence-based estimation of its cost effectiveness was carried out. Three independent meta-analyses were implemented to estimate the gain in uncorrected near visual acuity and best corrected visual acuity (vision lines) as well as the predictability (fraction of patients without need for reading aids) of multifocal supplementation. Study reports published between 1995 and 2004 (English or German language) were screened for appropriate key words. Meta effects in visual gain and predictability were estimated by means and standard deviations of the reported effect measures. Cost data were estimated by German DRG rates and individual lens costs; the cost effectiveness of multifocal cataract surgery was then computed in terms of its marginal cost effectiveness ratio (MCER) for each clinical benefit endpoint; the incremental costs of multifocal versus monofocal cataract surgery were further estimated by means of their respective incremental cost effectiveness ratio (ICER). An independent meta-analysis estimated the complication profiles to be expected after monofocal and multifocal cataract surgery in order to evaluate expectable complication-associated additional costs of both procedures; the marginal and incremental cost effectiveness estimates were adjusted accordingly. A sensitivity analysis comprised cost variations of +/- 10 % and utility variations alongside the meta effect estimate's 95 % confidence intervals. Total direct costs from the health care insurer's perspective were estimated 3363 euro, associated with a visual meta benefit in best corrected visual

Full Text Available The key informant methodology for case finding for childhood cataract was utilized in a rural population in Nigeria to identify suitable children who would benefit surgically from intervene for cataract and restore vision such children. It was however noticed that some parents who had children with cataract did not bring their children to the primary health center for examination and recommendation. The purpose of this study is to investigate the benefits of using the theatre for development approach in childhood cataract case finding. The delay in identification and referral of children with cataract at an appropriate age for surgical intervention and optical rehabilitation is the main cause of poor vision following surgery for the condition as amblyopia results. Therefore early presentation, identification, referral and surgical intervention as well as appropriate optical rehabilitation is the key to successful surgical outcome of childhood cataract and good visual prognosis. The theater for development (TfD approach methodology was implemented in a community in Akpabuyo local government are of Cross River state, Nigeria as a means to enhance community participation, health promotion and education and to complement the key informant methodology in case finding for childhood cataract. Three children with cataracts were referred by the community following the TfD intervention, for cataract surgery and uptake of follow up care after surgery. The TfD approach appears to be a useful method for encouraging community participation in the case finding of childhood cataract.

Full Text Available Aim. To study immune and antioxidant status of diabetic cataract patients and to assess the efficacy of preoperative preparation for diabetic cataract surgery to prevent intra- and postoperative complications and the efficacy of cataract treatment in metabolic syndrome patients. Patients and methods. 136 cataract patients (272 eyes were examined (mean age 62±3.2 years. Among these patients, women predominated (n = 74. Control group included 25 healthy volunteers (10 men and 15 women aged 32‑56 (mean age 44.3±2.4 years without ocular diseases (50 eyes. Two patient groups were examined. Group 1 included 78 patients (mean age 54±1.5 younger than 60 (52.5 % with similar lens morphological changes and metabolic disorders who were diagnosed with complicated (diabetic cataract. Group 2 included 58 patients with age-related cataract. Tear, anterior chamber (AC humor, and blood tests were performed. Immune status, lipid peroxidation parameters in tear fluid and blood, active peroxiredoxin 6 (PRDX6 and / or its breakdown fragments in tear fluid and AC humor were studied. In group 1 (age-related cataracts, somatic disorders were diagnosed in 4.5 % of cases, in group 2 (complicated cataracts, somatic disorders were diagnosed in 100 % of cases. Expression of protective enzymes against oxidative stress in tear fluid was studied. Activity of tear antioxidant enzymes under oxidative stress conditions in therapy and after cataract surgery was evaluated. Results. Postoperatively, increase in PRDX6 level was revealed in age-related cataract patients. The absence of phaco complications confirms these findings. In complicated (diabetic cataracts, PRDX6 level was 6‑times less than in age-related cataracts. Conclusions. Prophylaxis of inflammatory complications in age-related cataract patients can be performed using the following schedule: 0.5 % levofloxacin 4 times daily, bromfenac once daily.

Systematic reviews (SRs) are important for making clinical recommendations and guidelines. We analyzed methodological and reporting quality of pain-related SRs published in the top-ranking anesthesiology journals. This was a cross-sectional meta-epidemiological study. SRs published from 2005 to 2015 in the first quartile journals within the Journal Citation Reports category Anesthesiology were analyzed based on the Journal Citation Reports impact factor for year 2014. Each SR was assessed by 2 independent authors using Assessment of Multiple Systematic Reviews (AMSTAR) and Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) tools. Total score (median and interquartile range, IQR) on checklists, temporal trends in total score, correlation in total scores between the 2 checklists, and variability of those results between journals were analyzed. A total of 446 SRs were included. Median total score of AMSTAR was 6/11 (IQR: 4-7) and of PRISMA 18.5/27 (IQR: 15-22). High compliance (reported in over 90% SRs) was found in only 1 of 11 AMSTAR and 5 of 27 PRISMA items. Low compliance was found for the majority of AMSTAR and PRISMA individual items. Linear regression indicated that there was no improvement in the methodological and reporting quality of SRs before and after the publication of the 2 checklists (AMSTAR: F(1,8) = 0.22; P = .65, PRISMA: F(1,7) = 0.22; P = .47). Total scores of AMSTAR and PRISMA had positive association (R = 0.71; P reporting quality of pain-related SRs should be improved using relevant checklists. This can be remedied by a joint effort of authors, editors, and peer reviewers.

To compare the incidence of intraoperative complications during cataract surgery performed by left-handed and right-handed residents and to find predictor variables for complications in resident-performed surgery. Massachusetts Eye and Ear Infirmary, Boston, Massachusetts, USA. This retrospective chart review comprised cataract extractions performed by postgraduate fourth-year residents from July 1, 2001, to June 30, 2006. The incidence of posterior capsule tear and vitreous loss were the main outcomes. Univariate and multivariate logistic analyses incorporated the variables of patient age and sex; laterality of surgical eye; presence of diabetes mellitus, glaucoma, or age-related macular degeneration; history of vitrectomy; axial length; pseudoexfoliation; small pupils; white cataract; posterior polar cataract; handedness of resident; and academic quarter during which surgery occurred. Left-handed residents performed 170 (9.8%) of the 1730 surgeries. The incidence of posterior capsule tear and vitreous loss was significantly lower in surgeries performed by left-handed residents than in those performed by right-handed residents (P = .03 and Pleft-handed residents. Handedness and patient age were significant predictor variables for these complications.

We report the outcomes of BioMed Central's public consultation on implementing open data-compliant licensing in peer-reviewed open access journals. Respondents (42) to the 2012 consultation were six to one in favor (29 in support; 5 against; 8 abstentions) of changing our authors' default open access copyright license agreement, to introduce the Creative Commons CC0 public domain waiver for data published in BioMed Central's journals. We summarize the different questions we received in response to the consultation and our responses to them - matters such as citation, plagiarism, patient privacy, and commercial use were raised. In light of the support for open data in our journals we outline our plans to implement, in September 2013, a combined Creative Commons Attribution license for published articles (papers) and Creative Commons CC0 waiver for published data.
Full Text Available We propose the Maximal Mydriasis Test (MMT as a simple and safe means to provide the cataract surgeon with objective and dependable pre-operative information on the idiosyncratic mydriatic response of the pupil. The MMT results of a consecutive series of 165 eyes from 100 adults referred for cataract evaluation are presented to illustrate its practical applications and value. The results of the MMT allows the surgeon to anticipate problem eyes pre-operatively so that he can plan his surgical strategy more appropriately and effectively. Conversely, the surgeon can also appropriately and confidently plan surgical procedures where wide pupillary dilation is important. The MMT has also helped improve our cost-effectiveness by cutting down unnecessary delays in the operating room and enabling better utilisation of restricted costly resources.

We present an interventional case report of an 83-year-old woman who developed ocular hemosiderosis secondary to massive retinal and intravitreal bleeding associated with a choroidal neovascular membrane as a result of age-related macular degeneration. Anterior segment manifestations included low-grade inflammation, posterior synechiae, reversible hyperchromic heterochromia, and a mature cataract with "leopard spots." The longstanding vitreous hemorrhage was thought to be the etiology of these findings. At the request of the vitreoretinal surgeon, cataract surgery was performed to provide visualization of the posterior segment. However, the patient's visual potential was limited by her underlying retinal pathology. Neither author has a financial or proprietary interest in any material or method mentioned.

Glucose-6-phosphate dehydrogenase (G6PD) has an essential role in the defense against cellular oxidative injury. In neonates, the most common manifestation of G6PD deficiency is jaundice and hemolysis due to factors causing oxidative stress. Less known are the ocular associations described with G6PD deficiency, including cataracts. Oxidative injury is involved in the pathogenesis of almost all forms of cataracts, causing the lens proteins to undergo modifications, denaturation and form insoluble aggregates resulting in cataracts. Although cataracts in adult males have been reported in several studies, there are few reports of cataracts in infants with G6PD deficiency. We describe a preterm male neonate with G6PD deficiency who developed bilateral cataracts following an episode of neonatal sepsis and severe hemolysis necessitating an exchange blood transfusion.

Full Text Available Craig J Brown,1 Faical Akaichi21The Eye Center, Fayetteville, AR, USA; 2Scotland’s Rural College, Edinburgh, UKPurpose: To evaluate risk factors associated with posterior subcapsular cataract (PSC development and the relationship between vitamin D deficiency and etiology of PSC.Methods: Of 195 consecutive patients from a private ophthalmology practice, diagnosed with PSC, serum vitamin D3 (25-OH D levels were obtained for 175, and associations among risk factors, comorbidities, and PSC were assessed.Results: In all 175 PSC patients, mean 25-OH D levels were low (24 ng/mL ±11 SD compared with age/sex-matched standards. Significant differences in 25-OH D levels were noted between PSC subjects taking/not taking calcium supplements, systemic steroids, osteoporosis medications, etc. Alone, smoking status and calcium channel blockers and/or topical steroids use made no significant difference in PSC subjects 25-OH D levels, but two or more of these factors were associated with lowered levels of 25-OH D (P<0.001. Low vitamin D was correlated with female sex, autoimmune disease, and non-skin cancer diagnosis, but not with age, or other comorbidities or medication use. In five early-stage PSC patients taking 5,000 IU of 25-OH D daily for vitamin D deficiency, there was resolution of their cataracts during the 2-year follow-up period.Conclusion: Vitamin D levels for most PSC patients fell below the 30 ng/mL calcium homeostasis threshold. Some comorbidities and non-ophthalmic interventions are associated with the development of PSC at less depressed levels of 25-OH D. In this series, vitamin D deficiency was associated with PSC cataract, suggesting that raising the level of vitamin D intake may reduce PSC incidence.Keywords: posterior subcapsular, cataracts, vitamin D deficiency, risk factors, hypocalcemia, case report

Full Text Available Methylphenidate hydrochloride (Ritalin is the drug of choice for attention deficit hyperactivity disorder (ADHD. However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-corrected visual acuity was 6/60 in both eyes. Ocular examinations revealed intraocular pressure (IOP of 30 mmHg under medication, dense posterior subcapsular opacity of lens, pale disc with advanced cupping, and marked constriction of visual field. Despite maximal anti-glaucomatous medication, IOP still could not be controlled. The patient then received combined cataract and glaucoma surgery. Visual acuity improved and IOP was within normal limits in both eyes postoperatively. Large dose of methylphenidate may cause cataract and glaucoma. The mechanism remains unclear. Doctors should be aware of the possible ocular side effects of methylphenidate.

to evaluate the efficiency of new torsional phacoemulsification software (Ozil IP system) in hard nucleus cataract extraction. 45 eyes with hard senile cataract (degree III and IV) underwent phacoemulsification performed by the same surgeon, using the same technique (stop and chop). Infiniti (Alcon) platform was used, with Ozil IP software and Kelman phaco tip miniflared, 45 degrees. The nucleus was split into two and after that the first half was phacoemulsificated with IP-on (group 1) and the second half with IP-off (group 2). For every group we measured: cumulative dissipated energy (CDE), numbers of tip closure that needed manual desobstruction the amount of BSS used. The mean CDE was the same in group 1 and in group 2 (between 6.2 and 14.9). The incidence of occlusion that needed manual desobstruction was lower in group 1 (5 times) than in group 2 (13 times). Group 2 used more BSS compared to group 1. The new torsional software (IP system) significantly decreased occlusion time and balanced salt solution use over standard torsional software, particularly with denser cataracts.
Full Text Available Propensity for increased postoperative inflammation and capsular opacification, a refractive state that is constantly in a state of flux due to growth of the eye, difficulty in documenting anatomic and refractive changes due to poor compliance, and a tendency to develop amblyopia, makes management of cataract in the child different from that in the adult. The recent past has unraveled several caveats of pediatric cataract management - the importance of atraumatic surgery and complete removal of lens matter, benefits of in-the-bag intraocular lens(IOL implantation, role of titrating IOL power to counter refractive changes due to growth of the eye, prudery of continuously following these eyes for early detection of aphakic glaucoma and benefits of some surgical innovations. Although these promise to significantly improve our management of pediatric cataract, their long-term benefits are yet to be determined. We will also have to harness newer techniques, especially in the areas of wound construction and capsule management, and will have to develop effective strategies for the refractive management of infantile aphakia.

Background Radiation cataracts develop as a consequence of the effects of ionizing radiation on the development of the lens of the eye with an opaque lens reducing or eliminating the ability to see. Therefore, we would expect cataracts to be associated with reduced fitness in free-living animals. Methodology/Principal Findings We investigated the incidence of lens opacities typical of cataracts in more than 1100 free-living birds in the Chernobyl region in relation to background radiation. The incidence of cataracts increased with level of background radiation both in analyses based on a dichotomous score and in analyses of continuous scores of intensity of cataracts. The odds ratio per unit change in the regressor was 0.722 (95% CI 0.648, 0.804), which was less than odds ratios from investigations of radiation cataracts in humans. The relatively small odds ratio may be due to increased mortality in birds with cataracts. We found a stronger negative relationship between bird abundance and background radiation when the frequency of cataracts was higher, but also a direct effect of radiation on abundance, suggesting that radiation indirectly affects abundance negatively through an increase in the frequency of cataracts in bird populations, but also through direct effects of radiation on other diseases, food abundance and interactions with other species. There was no increase in incidence of cataracts with increasing age, suggesting that yearlings and older individuals were similarly affected as is typical of radiation cataract. Conclusions/Significance These findings suggest that cataracts are an under-estimated cause of morbidity in free-living birds and, by inference, other vertebrates in areas contaminated with radioactive materials.

Full Text Available Cataract surgery is one of the most successful and frequently performed operations worldwide, and yet cataract remains the commonest cause of global blindness. This is in part due to the shortage and uneven distribution of trained personnel in some countries. More worryingly, a high rate of cataract blindness also reflects poor visual outcomes after surgery, as has been documented in many RAAB (rapid assessment of avoidable blindness studies.

The numbers of systematic reviews (SRs) and meta-analyses (MAs) published in China have dramatically increased in recent years. Comprehensive analysis of their citation status may prove beneficial to the production and integration of high quality research, thereby increasing the quality of medical policy-making, research, and clinical practice. The Chinese Medical Citation Index (up to February 2010) was searched to identify SRs/MAs. Data were input using Microsoft Excel 2007 and statistical analysis was performed using SPSS 15.0 software. A total of 2224 SRs/MAs were included. Among the 591 different publications distributed from 1994 to 2009, the median publication count per publication was two (1-270). The total citation count was 2796, with an average of 1.26 citations per publication (0-57 citation). SRs/MAs that were never cited amounted to 1380 papers (62.1%), distributed in 272 journals (46.0%). MAs were easier to find than SRs. The major conditions affecting citation were whether or not the report was published in a Western field (r = 0.287, P = 0.000); whether or not the report was published in an "evidence-based" titled journal (r =-0.480, P = 0.002); and the length of time since publication (r = 0.455, P = 0.000). Since 2004, publication of SRs/MAs has exhibited a downward trend, forming a negative correlation with publication count. Over half of the SRs/MAs included had never been cited by the time research had concluded. In many other cases these reports exhibited extremely low citation rates. Citation of traditional Chinese medicine SRs/MAs exceeded that of Western medicine studies. This indirectly suggests that the quality of SRs/MAs usage is relatively low in China. This may be a result of various reasons and suggests that emphasis should be placed on raising the quality of SRs/MAs and significance of practical application. © 2012 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

To describe the methods and processes used in an evaluation of local journal subscriptions in a mental health trust and to suggest possible further areas of investigation were similar exercises to be undertaken again. Results from a user questionnaire were analysed along with e-journal usage statistics and data from local document supply activity. Journal reviews can yield surprising results. Carrying out a user survey is valuable in highlighting awareness of e-resources more generally and thus in providing evidence for marketing/information literacy initiatives. Future journal reviews should undertake impact analysis as potent evidence for continued expenditure on journals in this age of austerity. © 2011 The authors.

We retrospectively reviewed the results of radiotherapy for localized ocular adnexal MALT lymphoma (OAML) to investigate the risk factors of cataract. Sixty-seven patients with stage IE OAML treated with radiotherapy at Seoul St. Mary’s Hospital from 2001 to 2016 were included. Median treatment dose was 30 Gy. Lens protection was done in 52 (76%) patients. Radiation therapy (RT) extent was as follows: superficial (82.1%), tumor mass (4.5%), and entire orbital socket (13.4%). The risk factors for symptomatic cataract were analyzed using the Cox proportional hazard model. Median follow-up time was 50.9 months (range, 1.9 to 149.4 months). All patients were alive at the time of analysis. There were 7 recurrences and there was no local recurrence. Median time to recurrence was 40.4 months. There were 14 cases of symptomatic cataract. Dose >30 Gy had hazard ratio of 3.47 for cataract (p = 0.026). Omitting lens protection showed hazard ratio of 4.10 (p = 0.008). RT achieves excellent local control of ocular MALT lymphoma. Consideration of RT-related factors such as lens protection and radiation dose at the stage of RT planning may reduce the risk of RT-induced cataract after radiotherapy.

Over the past 20 years, the impact of technology has increased significantly in health care. The diversity of technology is growing and its knowledge scattered. The concept of technology is ambiguous in caring and nursing sciences and its ethics remains unidentified. To find evidence on how the concept of technology and its ethics are defined in caring and nursing sciences and practice. The purpose of this study is to describe and summarize the concept of technology and its ethics in the past nursing and caring literature. The integrative literature review of the past nursing and caring literature. The data were collected from caring and nursing journal articles from 2000 to 2013 focusing on technology and its ethics.The results were summarized and themed. Technology as a concept has three implications. First, technology is devices and products, including ICT and advanced, simple and assistive technology. Second, technology refers to a process consisting of methods for helping people. Third, technology as a service indicates the production of care by technology. The ethics of technology has not been established as a guiding principle. Some studies excluded ethical reflection completely. Many studies discussed the ethics of technology as benefits such as improved communication and symptoms management, and the simple use of e-health services whilst others remained critical presenting ethical problems such as unwillingness and the inability to use technology, or conflicts with human aspects or questions of inequality. In conclusion, this study indicates that technology as a concept is described diversely. The relation between technology and ethics is not a truism. Despite some evidence, more is needed to promote ethical care when using technology. © The Author(s) 2014.

Full Text Available BACKGROUND Control of childhood blindness is one of the priorities identified for achieving the goals of Vision-2020 by WHO. This is considered a priority because blind-years (number of years that a blind person lives after going blind due to childhood blindness are second only to cataract and half of childhood blindness is avoidable (treatable/preventable. Paediatric cataract accounts for 12% of the 1.4 million blind children globally. The prevalence of childhood cataract has been reported as 1 to 15 cases in 10,000 children in developing countries. Compared to industrialised countries, this figure is 10 times higher. Early detection and timely treatment of various childhood disorders such as congenital cataract are the most crucial factors for successful outcome. A suitable measure to address amblyopia and posterior capsule opacification post operatively is imperative for successful visual rehabilitation of such children. The objectives of this study were- 1 To study the clinical profile of paediatric cataract. 2 To evaluate the visual outcome after cataract surgery in these patients. 3 To evaluate different causes of visual impairment following management. MATERIALS AND METHODS A prospective study conducted at Karnataka institute of medical sciences department of ophthalmology from October 2015 to September 2016. All children below 14 years of age presenting with cataract will undergo thorough ophthalmologic examination and cataract surgery. RESULTS The results of the present study with 25 paediatric patients (36 eyes indicates that excellent vision can be expected after cataract surgery and posterior chamber IOL implantation coupled with appropriate amblyopia therapy. CONCLUSION The paediatric cataract patients are referred from primary health centers, and district hospital from north Karnataka to KIMS Hubli. All paediatric patients are from lower socio economic status. Early detection of cataracts and referrals to the ophthalmologist can
Full Text Available Cataract is the leading cause of 51% blindness case in the world. Cataract can only be cured trough surgery, but most people with cataract in Indonesia is not in undergoing surgery due to several factors. The increasing number of cataract victim whose not undergoing any treatment to cure them will resulting in increasing number of blindness case, so blindness cause by cataracts can be a public health problem. This research was conducted to determine the relationship of age, attitudes, knowledge and the cost of the action to perform cataract surgery. This research was an observational analytic study with cross sectional design. The samples were cataract patients in Undaan Eye Hospital Surabaya who were randomly selected using a simple random sampling based on medical records of 60 people. Data collection was done by taking secondary data and interviews to patients. Those variables was analyzed with chi square or Fisher’s exact with significancy level at 95%. The result showed that there were correlation between knowledge (p = 0.017, operating costs (p = 0.001 and attitude (0.000 while age was not related (p = 1.000, the actions to perform cataract surgery. The conclusion from this research was the attitude, knowledge and operating costs related to the actions to perform cataract surgery, while age was not related to the actions to perform cataract surgery. It is recommended to give through leaflets or other media in the lobby for improving patient education, counseling to the patient family, the doctor’s advice to convince patient for surgery.

Congenital cataract is the main cause of blindness in children, with significantly varying treatment effects. The development of axial length is an important factor that affects the prognosis of these children. However, when compared with the eyes of normal children, the mechanism of growth of the axial length is so complicated that the reported findings differ significantly in terms of the measuring apparatus, assessment methods, and statistical outcome, making the rule of axial length development still unclear. In this paper, we first review the process of axial length development in normal healthy children and compare different hypotheses about certain factors that could affect the development of axial length. The results of some current research about the characteristics of axial length development in congenital cataract children are then reviewed. Lastly, the advantages and disadvantages of current axial length measurements methods are compared and analyzed. The purpose of this review is to improve our understanding of the complexity and importance of axial length development and to suggest better use of axial length monitoring measurements in congenital cataract children for pediatric ophthalmologists, with the hope of offering assistance that will enhance long-term therapeutic effects for these children.

Full Text Available This overview of the media and conflict literature and case study of media coverage of peace offers a framework and guidance for peace journalism. Many studies show media rarely report conflict neutrally. Human psychology, journalistic norms, and structural constraints draw media away from complex historical reporting of violence. Limited systematic research on media coverage of peace is insufficient to direct response to prevalent war journalism. A case study of The Washington Report coverage of Middle East peace initiatives suggests problems in media coverage of peace. It demonstrates five trends in press orientations. Peace initiatives are: 1. political maneuvering and strategic posturing, 2. rhetorical games to mask intractable differences, 3. a charade among players with little belief in their success, 4. fragile and impermanent, and 5. an exercise in doublespeak and distortion. Peace journalists are divided between an activist, advocacy role for media and a definition of peace journalism as quality, objective journalism that includes under-represented perspectives to provide deeper and broader information. The divide reflects long-standing imprecision and ideological objectives in the fields of conflict studies, peace studies, conflict resolution, and more. Thus, economic theorists contend that industry structure and profit-motives drive media to privilege the powerful, limiting the potential for change. The propaganda model of media suggests peace journalism initiatives are impotent because media are a mouthpiece for government. Some say the realities of the post-Cold War world undermine quality journalism, and local media are an inefficient and limited mechanism to disseminate dissident ideas. Critical scholars view peace journalism as flawed, ineffectual, or certain to be co-opted. However, media texts are subject to multiple interpretations; cracks in the monolith offer opportunities for reform. Peace journalism must transform deeply

To report the early experience and complications during cataract surgery with a noncontact femtosecond laser system. Hong Kong Sanatorium and Hospital, Hong Kong Special Administrative Region, China. Retrospective case series. All patients had anterior capsulotomy or combined anterior capsulotomy and lens fragmentation using a noncontact femtosecond laser system (Lensar) before phacoemulsification. Chart and video reviews were performed retrospectively to determine the intraoperative complication rate. Risk factors associated with the complications were also analyzed. One hundred seventy eyes were included. Free-floating capsule buttons were found in 151 eyes (88.8%). No suction break occurred in any case. Radial anterior capsule tears occurred in 9 eyes (5.3%); they did not extend to the equator or posterior capsule. One eye (0.6%) had a posterior capsule tear. No capsular block syndrome developed, and no nuclei were dropped during irrigation/aspiration (I/A). Anterior capsule tags and miosis occurred in 4 eyes (2.4%) and 17 eyes (10.0%), respectively. Different severities of subconjunctival hemorrhages developed in 71 (43.8%) of 162 eyes after the laser procedure. The mean surgical time from the beginning to the end of suction was 6.72 minutes ± 4.57 (SD) (range 2 to 28 minutes). Cataract surgery with the noncontact femtosecond laser system was safe. No eye lost vision because of complications. Caution should be taken during phacoemulsification and I/A to avoid radial anterior capsule tears and posterior capsule tears.

Full Text Available BACKGROUND Cataract is the principal cause of avoidable blindness in India and throughout the world. Surgical removal of the cataractous lens remains the only effective treatment for management of cataract blindness. The success of cataract surgery is determined by best and earliest visual recovery. But the occurrence of postoperative astigmatism has become a major hurdle in achieving this goal. AIMS The study was designed to compare the amount of astigmatism following conventional extracapsular cataract extraction (ECCE and manual small incision cataract surgery (SICS. MATERIALS AND METHODS The study was carried out in 100 eyes of 75 patients aged between 50 and 80 years admitted for cataract surgery. Out of these, 50 eyes were operated by conventional extracapsular cataract extraction and 50 eyes by manual small incision cataract surgery. The patients were followed up at 2 nd , 4 th , 6 th and 8 th weeks. At each follow-up visual acuity, refraction and acceptance and keratometry were recorded and the findings analysed for astigmatism. RESULTS In the current study, the mean (SD astigmatism developed at the end of the 2 nd , 4 th and 6 th of follow-up was significantly lower in the SICS group as compared to the ECCE group (P<0.000. At the end of 8 weeks of follow-up, the mean (SD astigmatism of the SICS group was 0.64±0.56 D as compared to the mean (SD of the ECCE group of 1.39±86 D and the difference was found to be significant (p<0.014. CONCLUSION The current study concludes that manual small incision cataract surgery is a better technique to control postoperative astigmatism than conventional extracapsular cataract extraction.

Cataract though avoidable remains as leading cause of blindness in Nepal. Though, Himalaya Eye Hospital rendering high quality surgical service through its base hospital and out reach service in Gandaki Zone having cataract surgical rate is below 1500 per million. Therefore, it is mater of interest to investigate the reason and the finding would be helpful to plan the future cataract programme to CSR to desirable level, if we know the reason(s) that forced them living as blind in community and not seeking available surgical services. All person with cataract affecting their visual acuity to financial 24.1% and other clinical reason were found to be 12% as a reason for not seeking available surgical service. The cataract service marketing, eye health education disseminating the information on cataract and its curability is not found to be adequate. Therefore, the future cataract programme should give more concentration on creating awareness on cataract and subsidizing the available surgical service and service need to be brought to more proximity for the needy poor people.

This article raises awareness about the cost-effectiveness and carbon footprint of various cataract surgery techniques, comparing their relative carbon emissions and expenses: manual small-incision cataract surgery (MSICS), phacoemulsification, and femtosecond laser-assisted cataract surgery. As the most commonly performed surgical procedure worldwide, cataract surgery contributes significantly to global climate change. The carbon footprint of a single phacoemulsification cataract surgery is estimated to be comparable to that of a typical person's life for 1 week. Phacoemulsification has been estimated to be between 1.4 and 4.7 times more expensive than MSICS; however, given the lower degree of postoperative astigmatism and other potential complications, phacoemulsification may still be preferable to MSICS in relatively resource-rich settings requiring high levels of visual function. Limited data are currently available regarding the environmental and financial impact of femtosecond laser-assisted cataract surgery; however, in its current form, it appears to be the least cost-effective option. Cataract surgery has a high value to patients. The relative environmental impact and cost of different types of cataract surgery should be considered as this treatment becomes even more broadly available globally and as new technologies are developed and implemented.

There are indications that solar ultraviolet radiation (UVR) increases the risk of cataract, but there is only circumstantial evidence that metal welding, an important occupational source of UVR exposure, is a risk factor. The objective of this study is to unravel if metal welding increases the risk of cataract. We compared the risk of being diagnosed with cataract from 1987-2012 in a historic cohort of 4288 male metal arc welders against a reference group comprised of Danish skilled and unskilled male workers with similar age distribution. For the welders' cohort, information on welding was collected from questionnaires and, for both cohorts, information about cataract diagnosis and operation was gathered from Danish national registers. Using Cox regression analysis, the hazard ratio (HR) for cataract diagnosis and/or operation was calculated in the follow-up period adjusted for baseline data regarding age, diabetes, and social group. There were 266 welders and 29 007 referents with a diagnosis and/or operation for cataract. The unadjusted HR for cataract comparing ever-welders with referents was 1.07 [95% confidence interval (95% CI) 0.95-1.21] and the adjusted HR was 1.08 (95% CI 0.95-1.22). Age and diabetes were as expected strong risk factors. We found no increased risk of developing cataract among Danish metal welders who worked with arc welding from 1950-1985. This may be attributed to the effectiveness of personal safety equipment.

Cataract is defined as a lenticular opacity presenting usually with poor visual acuity. It is one of the most common causes of visual impairment worldwide. Early diagnosis demands the expertise of trained healthcare professionals, which may present a barrier to early intervention due to underlying costs. To date, studies reported in the literature utilize a single learning model for retinal image classification in grading cataract severity. We present an ensemble learning based approach as a means to improving diagnostic accuracy. Three independent feature sets, i.e., wavelet-, sketch-, and texture-based features, are extracted from each fundus image. For each feature set, two base learning models, i.e., Support Vector Machine and Back Propagation Neural Network, are built. Then, the ensemble methods, majority voting and stacking, are investigated to combine the multiple base learning models for final fundus image classification. Empirical experiments are conducted for cataract detection (two-class task, i.e., cataract or non-cataractous) and cataract grading (four-class task, i.e., non-cataractous, mild, moderate or severe) tasks. The best performance of the ensemble classifier is 93.2% and 84.5% in terms of the correct classification rates for cataract detection and grading tasks, respectively. The results demonstrate that the ensemble classifier outperforms the single learning model significantly, which also illustrates the effectiveness of the proposed approach.

In recent years there has been an increasing focus on human subject protection and on documentation of ethical review in published clinical research. The JAAD clearly states in its instructions to authors, which adhere to the guidelines set forth by the International Committee of Medical Journal Editors, "studies involving live human subjects must have been approved by the author's Institutional Review Board or its equivalent." To determine what proportion of prospective studies on human subjects submitted to the clinical trials and therapeutics section lacked mention of review by an ethics board and to determine the outcome of these manuscripts. We reviewed 150 prospective studies submitted from July 1, 2004 to January 16, 2006 to a single associate editor, who receives the majority of reports requiring ethics board review. Of 150 prospective studies, 36% (n = 54) had no mention of ethics review or consent, whereas 15% (n = 22) mentioned consent but not ethics review. Forty-two papers were returned asking for ethics information, and of these, 48% were resubmitted with confirmation of ethics review, 22% were withdrawn, 12% were never resubmitted, 12% responded that ethical review was not obtained, and 7% were clarified as exempt from review. Of the 150 papers, 45% were from US authors and 55% were from international authors. Sixty-seven percent of US papers and 35% of international papers included ethics board information (P

We discuss some theoretical approaches, experimental results and field data concerning wave phenomena in ocean near-bottom stratified flows. Such strong flows of cold water form everywhere in the Atlantic abyssal channels, and these currents play significant role in the global water exchange. Most interesting wave structures arise in a powerful cataract flows near orographic obstacles which disturb gravity currents by forced lee waves, attached hydraulic jumps, mixing layers etc. All these effects were observed by the authors in the Romanche and Chain fracture zones of Atlantic Ocean during recent cruises of the R/V Akademik Ioffe and R/V Akademik Sergei Vavilov (Morozov et al., Dokl. Earth Sci., 2012, 446(2)). In a general way, deep-water cataract flows down the slope are similar to the stratified flows examined in laboratory experiments. Strong mixing in the sill region leads to the splitting of the gravity current into the layers having the fluids with different densities. Another peculiarity is the presence of critical layers in shear flows sustained over the sill. In the case under consideration, this critical level separates the flow of near-bottom cold water from opposite overflow. In accordance with known theoretical models and laboratory measurements, the critical layer can absorb and reflect internal waves generated by the topography, so the upward propagation of these perturbations is blocked from above. High velocity gradients were registered downstream in the vicinity of cataract and it indicates the existence of developed wave structures beyond the sill formed by intense internal waves.

Thirteen eyes of 55 consecutive patients treated with brachytherapy for malignant melanoma of the choroid developed postirradiation cataracts. Cataract development was more common in older patients and in patients with larger and more anterior tumors. Eleven eyes had extracapsular cataract extraction and intraocular lens implantation. Initial visual improvement occurred in 91% of eyes, with an average improvement of 5.5 lines. Visual acuity was maintained at 20/60 or better in 55% of the eyes over an average period of follow-up of 24 months (range, 6 to 40 months). These data suggest that, visually, cataract extraction can be helpful in selected patients who develop a cataract after brachytherapy for malignant melanoma of the choroid

The authors surveyed 21 editors and reviewers from major psychology journals to identify and describe the statistical and design errors they encounter most often and to get their advice regarding prevention of these problems. Content analysis of the text responses revealed themes in 3 major areas: (a) problems with research design and reporting (e.g., lack of an a priori power analysis, lack of congruence between research questions and study design/analysis, failure to adequately describe statistical procedures); (b) inappropriate data analysis (e.g., improper use of analysis of variance, too many statistical tests without adjustments, inadequate strategy for addressing missing data); and (c) misinterpretation of results. If researchers attended to these common methodological and analytic issues, the scientific quality of manuscripts submitted to high-impact psychology journals might be significantly improved.

To evaluate the serial changes in anterior chamber depth (ACD) and angle parameters early after cataract surgery using anterior segment optical coherence tomography (ASOCT). This was a retrospective chart review, case-control study; 150 eyes of 106 patients who underwent cataract surgery. Based on ACD and angle findings, the eyes were classified into two groups, open-angle eyes (87 eyes) and narrow-angle eyes (63 eyes). ASOCT was used to measure ACD and angle parameters (angle opening distance, angle recess area, trabecular iris space area, and trabecular iris angle (TIA ). Serial changes in each group were measured before and 1 day, 1 week, and 1 month after cataract surgery, and the differences between the two groups were compared. ACD and all angle parameters in both groups at each examination time after cataract surgery were significantly different from the preoperative values (p < 0.01). In addition, all angle parameters significantly differed between the two groups at each examination time after cataract surgery (p < 0.001). However, ACD after surgery was not significantly different, irrespective of ACD before surgery. ACD and TIA500 both showed significantly greater changes from before surgery to 1 day after surgery in narrow-angle eyes compared to open-angle eyes (p < 0.001). Cataract surgery increases ACD and all angle parameters early after the surgery. However, the degree of angle widening in narrow-angle eyes was not as much as that in open-angle eyes, suggesting that factors other than the lens influence the angle closure.

To report the long-term results of temporary piggyback IOL implantation in congenital cataract and to compare the clinical outcomes of temporary piggyback IOL with those of single IOL implantation. This is a retrospective, comparative, interventional study. The medical records of all consecutive patients who underwent cataract extraction and single or temporary piggyback IOL implantation within the first 3 years of life from 1999 to 2013 at Samsung Medical Center were reviewed. Twenty-eight eyes from 18 patients underwent single IOL implantation (monopseudophakia group), and 32 eyes of 20 patients underwent temporary piggyback IOL implantation in congenital cataract surgery (polypseudophakia group). The mean age at initial cataract surgery was 15.8 months in the monopseudophakia group and 11.1 months in the polypseudophakia group (P = 0.144). The average follow-up duration was 133 months in the monopseudophakia group and 120 months in the polypseudophakia group (P = 0.391). The best-corrected visual acuity at the last visit was 0.36 logMAR in the monopseudophakia group and 0.55 logMAR in the polypseudophakia group (P = 0.044). Four (14%) and 14 (44%) reoperations for complications within the anterior segment were performed in the monopseudophakia group and polypseudophakia group, respectively (P = 0.042). Four cases (14.3%) in the monopseudophakia group and 13 cases (40.6%) in the polypseudophakia group had a glaucoma-related adverse event (P = 0.086). Compared with primary single IOL implantation in congenital cataract, temporary piggyback IOL implantation produced worse visual acuity, higher reoperation rate, and higher risk of secondary glaucoma. Temporary piggyback IOL implantation does not have benefit in congenital cataract.

To characterize the role of Big Data in evaluating quality of care in ophthalmology, to highlight opportunities for studying quality improvement using data available in the American Academy of Ophthalmology Intelligent Research in Sight (IRIS) Registry, and to show how Big Data informs us about rare events such as endophthalmitis after cataract surgery. Review of published studies, analysis of public-use Medicare claims files from 2010 to 2013, and analysis of IRIS Registry from 2013 to 2014. Statistical analysis of observational data. The overall rate of endophthalmitis after cataract surgery was 0.14% in 216 703 individuals in the Medicare database. In the IRIS Registry the endophthalmitis rate after cataract surgery was 0.08% among 511 182 individuals. Endophthalmitis rates tended to be higher in eyes with combined cataract surgery and anterior vitrectomy (P = .051), although only 0.08% of eyes had this combined procedure. Visual acuity (VA) in the IRIS Registry in eyes with and without postoperative endophthalmitis measured 1-7 days postoperatively were logMAR 0.58 (standard deviation [SD]: 0.84) (approximately Snellen acuity of 20/80) and logMAR 0.31 (SD: 0.34) (approximately Snellen acuity of 20/40), respectively. In 33 547 eyes with postoperative VA after cataract surgery, 18.3% had 1-month-postoperative VA worse than 20/40. Big Data drawing on Medicare claims and IRIS Registry records can help identify additional areas for quality improvement, such as in the 18.3% of eyes in the IRIS Registry having 1-month-postoperative VA worse than 20/40. The ability to track patient outcomes in Big Data sets provides opportunities for further research on rare complications such as postoperative endophthalmitis and outcomes from uncommon procedures such as cataract surgery combined with anterior vitrectomy. But privacy and data-security concerns associated with Big Data should not be taken lightly. Copyright © 2015 Elsevier Inc. All rights reserved.

School psychologists in the United States are not nearly as diverse demographically as the students they serve (T.K. Fagan & P.S. Wise, 2000). A.H. Miranda and P.B. Gutter (2002) investigated the number of diversity-related articles in four leading school psychology journals from 1990 to 1999 and found that there was an increase in the…

It is well documented that fathers have a significant influence on their children's success in school. To examine the ways in which fathers have been represented in school psychology literature, the authors searched over 1,000 recent articles published in four leading U.S. school psychology journals ("Psychology in the Schools," "School Psychology…
