RESUMO
RATIONALE AND KEY POINTS: While clinical reflection has been an essential aspect of nursing practice for many years, some nurses may still find it challenging to constructively engage with this process and may not recognise the benefits and learning that can result from it. This article provides practical guidance for nurses on how to undertake reflection, to support them to reflect regularly as part of their practice. ⢠Reflection is a process of engaging with and learning from one's thoughts, emotions and actions in a supportive and critical manner.⢠Reflection can assist nurses to learn from practice, support team working and promote self-care.⢠Nurses can reflect alone or with others, and there are various structured models of reflection that they can use to support them. REFLECTIVE ACTIVITY: 'How to' articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: ⢠How you think you could use this article to improve your practice in undertaking structured clinical reflection.⢠How you could use this resource to educate your colleagues about the process of reflection.
RESUMO
PURPOSE: To characterize and compare residual retinal changes of spontaneously regressing retinopathy of prematurity (ROP) at termination of acute-phase retinal screening examinations. METHODS: A retrospective chart review of 521 infants screened for ROP from 2016 to 2019 was performed. Data were collected on patients with at least stage 1 ROP, but who were not treated. The primary outcome measure was presence of residual fibrotic retinal tissue at termination of acute ROP screening examinations. Secondary outcomes included: type of residual fibrotic retinal tissue, persistent avascular retina, vitreous hemorrhage, and retinal detachment. A novel grading system was used to categorize findings. Comparisons between groups were made using Fisher exact tests. RESULTS: A total of 255 eyes met inclusion criteria. A total of 206 of 255 eyes (81%) showed persistent avascular retina, whereas 57 of 255 eyes (22%) showed residual fibrotic retinal tissue at termination of acute screening. All eyes with previous stage 3 ROP showed residual fibrotic retinal tissue (8 of 8 eyes, 100%). Eyes whose highest stage of ROP was stage 2 showed more residual fibrotic retinal tissue at termination of acute screening (40 of 73 eyes, 55%) compared to eyes whose highest stage was stage 1 (9 of 174, 5%) (P < .0001). Stage 3 eyes were excluded from this comparison due to the small sample size. One eye had vitreous hemorrhage at post-menstrual age 44 1/7 weeks. No eyes had retinal detachment. CONCLUSIONS: Despite meeting at least one of the criteria for termination of acute ROP screening, residual fibrotic retinal tissue and persistent avascular retina are common after spontaneous regression of ROP. Further investigation into the long-term clinical significance of these residual changes is warranted. [J Pediatr Ophthalmol Strabismus. 2023;60(5):359-364.].
RESUMO
Molluscum contagiosum causes umbilicated periocular lesions, which commonly affect children. Topical clear nail polish for treatment of molluscum has been reported anecdotally, but there are few reports in the medical literature. We report the case of an eyelid molluscum lesion in an 8-year-old girl that resolved with 4 topical applications of nail polish over 6 weeks.

PURPOSE: To compare characteristics of laser treatment for high-risk type 1 retinopathy of prematurity (ROP) in eyes treated with primary laser versus laser after an initial treatment with intravitreal anti-vascular endothelial growth factor (anti-VEGF). METHODS: The medical records of consecutive patients at a single academic institution treated for type 1 ROP before 36 weeks' postmenstrual age with primary laser versus laser after initial treatment with anti-VEGF were reviewed retrospectively. Outcome measures were laser spot number, mean laser power, total laser energy (Joules), and retinal vascularization to the nasal ora at time of laser treatment. RESULTS: Compared with the 46 eyes treated with primary laser, the 46 eyes treated with laser after anti-VEGF required fewer spots (mean, 775 vs 1418 [P < 0.01]), less power (182 vs 223 mW [P < 0.01]), and less total energy (27 vs 61 Joules [P < 0.01]), and showed greater vascularization to the nasal ora at the time of laser treatment (47.8% vs 6.5% [P < 0.01]). CONCLUSIONS: In our study cohort, laser after initial anti-VEGF treatment may have allowed for greater retinal vascularization and been less destructive than primary laser for high-risk type 1 ROP.

All nurses and healthcare workers have a vital role in caring for people with a life-limiting prognosis. The importance of this role was accentuated during the widespread loss of life resulting from the coronavirus disease 2019 (COVID-19) pandemic. This article revisits the crucial role of nurses in the care of people with advanced disease, while outlining how nurses can provide evidence-based palliative and end of life care. The author explores some of the essential elements of symptom management in advanced disease and presents a series of short case studies to support nurses' critical reflection.

Despite recent discussions and campaigns to widen nursing's appeal to people of diverse gender identities, it continues to be perceived as a largely female profession. In the context of an ageing workforce, and alongside recruitment and retention challenges, efforts should be directed at developing a more inclusive profession rather than focusing on why people other than women do not become nurses. To attract more men, transgender people and those who identify as nonbinary, as well as women, the approach to nursing recruitment needs to change. The profession must develop a more inclusive culture and examine and promote the advantages that gender diversity can bring to nursing. This article explores the lack of gender diversity in contemporary nursing, briefly examines the history of gender in nursing, and considers how the profession might evolve into a more gender-diverse and inclusive workforce.

Purpose: We aim to compare the incidence of corneal epithelial defects after laser for retinopathy of prematurity (ROP) with and without the use of postoperative erythromycin ointment. Methods: In this retrospective observational cohort study, a total of 100 infants (200 eyes) consecutively treated with laser for ROP between 2012 and 2018. The primary outcome was presence or absence of corneal epithelial defect using fluorescein on bedside examination within the first week following laser for ROP. Additional data assessed included: the use of postoperative prophylactic erythromycin ointment for 1 week, postoperative day on which examination using fluorescein occurred, presence of corneal opacity, gender, birth weight, and gestation age. The presence or absence of postoperative corneal epithelial defects was compared between eyes receiving postoperative erythromycin ointment or not using a Fisher's exact test. Results: Postoperative corneal epithelial defects were more common in eyes which did not receive postoperative erythromycin (7 of 40 eyes; 17.5%), compared to eyes which did receive erythromycin (1 of 160 eyes; 0.6%; P < 0.0001). Postoperative bedside examinations with fluorescein were performed within 2 days of surgery on 136 of 200 of eyes (68%). Corneal opacities were noted in 3 of 200 eyes (1.5%). Conclusion: We observed less corneal epithelial defects in eyes which received postoperative erythromycin ointment for 1 week after laser for ROP than in those which did not. While multiple variables may influence the presence or absence of postoperative corneal epithelial defects following laser for ROP, consideration for postoperative lubricating ointment following laser for ROP seems reasonable.

PURPOSE: To compare rates of short-term retinal detachment (RD) of infants treated for type 1 retinopathy of prematurity (ROP) with intravitreal anti-vascular endothelial growth factor (VEGF) therapy with infants treated with laser therapy. The choice between these 2 treatments remains controversial. Comparative data are limited and describe re-treatment rates rather than retinal structural outcomes predictive of long-term vision. Anti-vascular endothelial growth factor acts faster than laser therapy, which may be beneficial for more aggressive ROP. DESIGN: Nonrandomized, comparative cohort study. PARTICIPANTS: The study included 1167 eyes of 640 infants treated for type 1 ROP. Among these, 164 eyes received anti-VEGF therapy and 1003 eyes received laser therapy. METHODS: Pretreatment and posttreatment examinations and treatments were completed by ophthalmologists with expertise in ROP. The study was a secondary analysis of data from the retrospective Postnatal Growth and Retinopathy of Prematurity Study (G-ROP) 1 study (2006-2012) and the prospective G-ROP 2 study (2015-2017). MAIN OUTCOME MEASURES: Rate of RD (ROP stages 4A, 4B, or 5) within 8 weeks of initial treatment, an end point predictive of poor long-term vision. The results were stratified by postmenstrual age (PMA) at treatment as occurring before versus at or after 36 weeks and 0 days, because earlier disease may be considered more aggressive. RESULTS: Among 458 eyes treated before PMA 36 weeks and 0 days, the short-term RD rate was higher after laser therapy (29/368 eyes [7.9%]) than after anti-VEGF therapy (0/90 eyes [0%]; P < 0.001). Of 709 eyes treated at or after PMA 36 weeks and 0 days, short-term RD risk did not differ between groups (laser [20/635 eyes], 3.1%; anti-VEGF [1/74 eyes], 1.4%; P = 0.27). CONCLUSIONS: Anti-vascular endothelial growth factor therapy results in better short-term structural outcomes than laser therapy when type 1 ROP is treated before 36 weeks' PMA. After this age, both treatments have very low rates of short-term RD. The faster action of anti-VEGF agents likely is responsible for these findings.

PURPOSE: To compare respiratory outcomes after treatment of retinopathy of prematurity (ROP) between infants treated with laser therapy under general anesthesia and infants treated with intravitreal bevacizumab under bedside sedation. DESIGN: Retrospective cohort study. PARTICIPANTS: One hundred thirty-eight consecutive infants treated for ROP from September 2010 through September 2018 at 1 institution. METHODS: Retrospective medical, procedural, and ophthalmologic data were collected, including preprocedure (baseline) and postprocedure (24 hours, 48 hours, 7 days, and 28 days) respiratory status, birth weight, gestational age, gender, ROP treatment method, postmenstrual age at treatment, and coincident nonocular procedures during anesthesia. Respiratory outcomes at 48 hours were compared between infants treated with laser therapy under general anesthesia and infants treated with intravitreal bevacizumab under local sedation using multivariate logistic regression analysis to control for potentially confounding factors. MAIN OUTCOME MEASURES: Proportion of infants who had returned to their respiratory baseline by 48 hours after ROP treatment. RESULTS: Return to respiratory baseline was significantly less common among 119 infants initially treated with laser therapy compared with 19 infants initially treated with bevacizumab at 24 hours (40% vs. 74%; P = 0.0115), 48 hours (53% vs. 79%; P = 0.0453), and 7 days (79% vs. 100%; P = 0.0242). In a multivariate logistic regression analysis, infants treated with laser therapy were less likely to return to respiratory baseline at 48 hours (odds ratio, 0.14; 95% confidence interval, 0.04-0.54). At 28 days, no difference was found between groups (laser, 97%; bevacizumab, 100%; P > 0.99). CONCLUSIONS: Infants treated with intravitreal bevacizumab using bedside sedation returned to their preprocedure respiratory baseline faster than infants treated with laser under general anesthesia, with the differences persisting at least to 7 days or more after the procedure.

This article explores the spiritual pain that patients may experience, which is often hidden or overlooked in healthcare settings that tend to focus on managing physical manifestations of pain. As part of their role in responding to patients' needs, nurses need to be willing to engage with spirituality, which is an important aspect of many people's lives. This article examines the meaning of spirituality and how spirituality may - or may not - relate to religious beliefs. It describes a whole-person approach to understanding the physical, social, emotional and spiritual dimensions of pain, and how this may assist nurses in recognising and addressing patients' spiritual needs. The article also explores attributes, skills and resources that can support nurses in responding to spiritual pain, including a caring presence, courage, compassion, and respect for other people's beliefs and values.

PURPOSE: To perform a stratified comparison of the short-term risk of retinal detachment after treatment of type 1 retinopathy of prematurity treated with panretinal photocoagulation laser versus intravitreal bevacizumab. METHODS: The medical records of consecutive infants treated for type 1 ROP between 2010 and 2018 were retrospectively reviewed. An a priori decision was made to divide infants into two groups, those treated before postmenstrual age (PMA) of 36 0/7 weeks and those treated at or after PMA of 36 0/7 weeks. The primary outcome was presence of any retinal detachment (stage 4A, 4B, or 5) during the 8 weeks following treatment. RESULTS: A total of 222 eyes of 115 infants were included. In eyes treated before 36 0/7 weeks' PMA, retinal detachment occurred in 0 of 34 eyes treated initially with bevacizumab compared with 9 of 56 (16%) treated with laser (P = 0.0112); in eyes treated at or after 36 0/7 weeks, in 0 of 2 eyes treated with bevacizumab and 1 of 130 eyes (0.8%) treated with laser. CONCLUSIONS: The short-term risk of retinal detachment among infants requiring treatment for type 1 ROP prior to 36 0/7 weeks' PMA was lower in eyes treated with intravitreal bevacizumab than in eyes treated with laser, presumably due to the faster effect of bevacizumab in eyes that have more aggressive ROP.

PURPOSE: Spasmus nutans is an acquired form of nystagmus that is classically associated with torticollis and titubations of the head, often presenting in the first year of life and spontaneously resolving within the next 2 years. The purpose of our study was to record and characterize the long-term prognosis of children diagnosed with spasmus nutans. METHODS: All patients under the age of 21 years with a diagnosis of spasmus nutans were included. Parameters of age, nystagmus symmetry and quality, presence of titubations, torticollis, and strabismus, and findings on CT or MRI were recorded. RESULTS: Our 22 patients had an average age of onset of 9.8 and a follow-up of 62.6 months. Nystagmus was unilateral in 5 children, asymmetric in 5, symmetric in 10, and inapparent in 2. Titubations were identified in 10 and torticollis in 7. Nystagmus persisted in 16 of 20 children, titubations in 3, and torticollis in 6. Neuroimaging, performed on 17 of the 22 children, was negative for any space-occupying lesions. CONCLUSION: In conclusion, we are reluctant to assure parents of children who have even the most typical spasmus nutans that their child will be normal after a predictable interval. Instead, we advise them that many children do well, assuming normal imaging, but that nystagmus, torticollis, and even titubations may persist. Follow-up, especially for strabismus and amblyopia, should be continued throughout childhood.

PURPOSE: Although much literature has focused on various techniques to repair epiblepharon, no study has addressed how frequently surgical intervention is required. METHODS: The authors tabulated data from all patients with epiblepharon seen over the past 15 years. RESULTS: Eighty-nine patients were included, 61 (69%) with tearing, discharge, conjunctival injection, or eye rubbing. Trichiasis was present in 15 cases (17%), 6 (7%) with corneal staining. In all cases, the initial treatment was conservative: antibiotic ointment or tear substitutes in 73 cases with trichiasis, symptoms of irritation, or corneal changes and observation in the remaining 16 cases. Three children (3%) were referred for eyelid surgery because of persistent symptoms. No patient had corneal scarring or long-term complications. CONCLUSIONS: Although vision-threatening complications can result, a trial of topical antibiotic ointment and/or ocular lubricants was effective in nearly all patients. Most resolved with minimal symptoms. The few eventually requiring eyelid surgery suffered no long-term complications. The authors recommend a trial of conservative treatment before eyelid surgery is undertaken. [J Pediatr Ophthalmol Strabismus. 2017;54(1):15-16.].

The authors describe two premature infants who developed stage 3, zone I retinopathy of prematurity (ROP) with plus disease in both eyes, despite limited exposure to supra-ambient oxygen. Both infants received noninvasive respiratory support for several weeks. Both cases are notable because the ROP was more posterior and aggressive than is typical for the gestational ages or birth weights. These cases are insufficient to make definitive conclusions regarding the factors that cause ROP. Further investigation is required to determine if there is an association between the use of non-invasive respiratory support, even in the absence of supra-ambient oxygen, and severe ROP development.

PURPOSE: Many children present with excessive blinking. Categorization, associated conditions, and prognosis are controversial. METHODS: All children with excessive blinking were reviewed, excluding those with known uveitis, glaucoma, or obvious eyelid abnormalities. Parents were telephoned for follow-up. RESULTS: No ocular pathology was identified in 31 of 34 children with excessive blinking (91%). Parents were able to report a specific cause of blinking in 7 (21%). In 24 of 34 (71%), parents reported complete resolution of excessive blinking. No new ophthalmologic diagnoses were uncovered on follow-up. CONCLUSIONS: Episodes of excessive blinking rarely indicate neurologic disorders and frequently resolve spontaneously.

More than two billion people are micronutrient deficient. Polished grains of popular rice varieties have concentration of approximately 2 µg g(-1) iron (Fe) and 16 µg g(-1) zinc (Zn). The HarvestPlus breeding programs for biofortified rice target 13 µg g(-1) Fe and 28 µg g(-1) Zn to reach approximately 30% of the estimated average requirement (EAR). Reports on engineering Fe content in rice have shown an increase up to 18 µg g(-1) in glasshouse settings; in contrast, under field conditions, 4 µg g(-1) was the highest reported concentration. Here, we report on selected transgenic events, field evaluated in two countries, showing 15 µg g(-1) Fe and 45.7 µg g(-1) Zn in polished grain. Rigorous selection was applied to 1,689 IR64 transgenic events for insert cleanliness and, trait and agronomic performances. Event NASFer-274 containing rice nicotianamine synthase (OsNAS2) and soybean ferritin (SferH-1) genes showed a single locus insertion without a yield penalty or altered grain quality. Endosperm Fe and Zn enrichment was visualized by X-ray fluorescence imaging. The Caco-2 cell assay indicated that Fe is bioavailable. No harmful heavy metals were detected in the grain. The trait remained stable in different genotype backgrounds.

We report 2 cases of unilateral retinal arteriovenous malformation (AVM) with previously unreported anomalies of the inner retinal layers detected on spectral domain optical coherence tomography (SD-OCT): a 5-year-old girl with a large unilateral retinal AVM, ipsilateral visual acuity of 20/200, and ipsilateral intracranial AVM; and a 10-year-old boy with a large unilateral retinal AVM, ipsilateral visual acuity of 20/20, ipsilateral temporal visual field defects, and no intracranial AVM. Both macular SD-OCT findings showed multiple large inner retinal vessels that created a prominent shadowing artifact, retinal thickening, and speckling and heterogeneity of inner retinal layers.

Biofortification of rice (Oryza sativa L.) using a transgenic approach to increase the amount of iron in the grain is proposed as a low-cost, reliable, and sustainable solution to help developing countries combat anemia. In this study, we generated and evaluated a large number of rice or soybean ferritin over-accumulators in rice mega-variety IR64, including marker-free events, by introducing soybean or rice ferritin genes into the endosperm for product development. Accumulation of the protein was confirmed by ELISA, in situ immunological detection, and Western blotting. As much as a 37- and 19-fold increase in the expression of ferritin gene in single and co-transformed plants, respectively, and a 3.4-fold increase in Fe content in the grain over the IR64 wild type was achieved using this approach. Agronomic characteristics of a total of 1,860 progenies from 58 IR64 single independent transgenic events and 768 progenies from 27 marker-free transgenic events were evaluated and most trait characteristics did not show a penalty. Grain quality evaluation of high-Fe IR64 transgenic events showed quality similar to that of the wild-type IR64. To understand the effect of transgenes on iron homeostasis, transcript analysis was conducted on a subset of genes involved in iron uptake and loading. Gene expression of the exogenous ferritin gene in grain correlates with protein accumulation and iron concentration. The expression of NAS2 and NAS3 metal transporters increased during the grain milky stage.
RESUMO
PURPOSE: To determine the effectiveness of a series of policy changes designed to increase the attendance rate for outpatient retinopathy of prematurity (ROP) screening examinations. METHODS: We retrospectively reviewed the records of consecutive neonatal intensive care unit patients before and after the implementation of policy changes. Policy changes included parent education forms, streamlined scheduling, and creation of a log for all patients seen. The primary outcome measure was attendance rates for the first outpatient appointment after discharge. The Fisher exact test was used to compare rates between the two groups. RESULTS: Before the policy was implemented, 22 of 52 (42%) neonates and their caregivers attended their first outpatient ROP screening examination on the recommended date. This rate improved significantly after policy implementation, when 46 of 57 (81%) neonates and their caregivers were seen on the recommended date (P < 0.01). The number of patients who ultimately met the criteria for conclusion of acute retinal screening examinations also significantly improved, from 47 of 52 (90%) of neonates in the pre-implementation group to 57 of 57 (100%) in the post-implementation group (P = 0.02). CONCLUSIONS: The attendance rates for initial outpatient ROP examinations and the number of patients who ultimately met criteria for conclusion of acute retinal screening examinations significantly improved after the implementation of new policies.
