RESUMEN

PURPOSE: Pituitary adenomas affect patients' quality-of-life (QoL) across several domains, with long-term implications even following gross-total resection or disease remission. While clinical outcomes can assess treatment efficacy, they do not capture variations in QoL. We present the development and validation of a patient reported outcome measure (PROM) for patients with pituitary adenomas undergoing transsphenoidal surgery. METHODS: The COSMIN checklist informed the development of the pituitary outcome score (POS). Consecutive patients undergoing surgical treatment for suspected pituitary adenoma at a single centre were included prospectively. An expert focus group and patient interviews informed item generation. Item reduction was conducted through exploratory factor analysis and expert consensus, followed by assessment of the tool's validity, reliability, responsiveness, and interpretability. RESULTS: 96 patients with a median age of 50 years validated the POS. The final questionnaire included 25 questions with four subscales: EQ-5D-5L-QoL, Visual Symptoms, Endocrine Symptoms and Nasal Symptoms. CONCLUSION: The POS is the first validated PROM for patients undergoing transsphenoidal surgery for a pituitary adenoma. This PROM could be integrated into contemporary practice to provide patient-centred outcomes assessment for this patient group, aligning more closely with patient objectives.

RESUMEN

BACKGROUND: Atopic keratoconjunctivitis (AKC) and vernal keratoconjunctivitis (VKC) are severe and potentially sight-threatening allergic eye diseases characterised by chronic inflammation of the ocular surface. Both topical and systemic treatments are used. This Cochrane Review focuses on systemic treatments. OBJECTIVES: To assess the effects of systemic treatments (including corticosteroids, NSAIDS, immunomodulators, and monoclonal antibodies), alone or in combination, compared to placebo or other systemic or topical treatment, for severe AKC and VKC in children and young people up to the age of 16 years. SEARCH METHODS: We searched CENTRAL, Ovid MEDLINE, Ovid Embase, the ISRCTN registry, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). There were no restrictions to language or year of publication. We last searched the electronic databases on 17 February 2020. SELECTION CRITERIA: We searched for randomised controlled trials (RCTs) that involved systemic treatments in children aged up to 16 years with a clinical diagnosis of AKC or VKC. We planned to include studies that evaluated a single systemic medication versus placebo, and studies that compared two or multiple active treatments. DATA COLLECTION AND ANALYSIS: We used standard methods expected by Cochrane. MAIN RESULTS: No trial met the inclusion criteria of this Cochrane Review. No RCTs have been carried out on this topic. AUTHORS' CONCLUSIONS: There is currently no evidence from randomised controlled trials regarding the safety and efficacy of systemic treatments for VKC and AKC. Trials are required to test efficacy and safety of current and future treatments. Outcome measures need to be developed which can capture both objective clinical and patient-reported aspects of the condition and treatments.

RESUMEN

OBJECTIVES: To determine the associations of breast milk intake after birth with neurological outcomes at term equivalent and 7 years of age in very preterm infants STUDY DESIGN: We studied 180 infants born at <30 weeks' gestation or <1250 grams birth weight enrolled in the Victorian Infant Brain Studies cohort from 2001-2003. We calculated the number of days on which infants received >50% of enteral intake as breast milk from 0-28 days of life. Outcomes included brain volumes measured by magnetic resonance imaging at term equivalent and 7 years of age, and cognitive (IQ, reading, mathematics, attention, working memory, language, visual perception) and motor testing at 7 years of age. We adjusted for age, sex, social risk, and neonatal illness in linear regression. RESULTS: A greater number of days on which infants received >50% breast milk was associated with greater deep nuclear gray matter volume at term equivalent age (0.15 cc/d; 95% CI, 0.05-0.25); and with better performance at age 7 years of age on IQ (0.5 points/d; 95% CI, 0.2-0.8), mathematics (0.5; 95% CI, 0.1-0.9), working memory (0.5; 95% CI, 0.1-0.9), and motor function (0.1; 95% CI, 0.0-0.2) tests. No differences in regional brain volumes at 7 years of age in relation to breast milk intake were observed. CONCLUSION: Predominant breast milk feeding in the first 28 days of life was associated with a greater deep nuclear gray matter volume at term equivalent age and better IQ, academic achievement, working memory, and motor function at 7 years of age in very preterm infants.

RESUMEN

BACKGROUND: Eye emergencies constitute a significant portion of attendances to general Emergency Departments (EDs) in the UK, therefore it is important to assess the confidence of doctors who work in this setting in managing these potentially sight- and life-threatening presentations. This systematic review aims to assess the confidence of UK doctors working in general EDs in managing ophthalmic emergencies. METHODS: MEDLINE (Ovid), EMBASE (Ovid), ProQuest Central and Web of Science databases and grey literature were searched from inception to 1 October 2022 for publications that (1) featured doctors working in UK general EDs, (2) assessed doctors' confidence in managing ophthalmic emergencies, (3) contained original data, (4) were full-text, and (5) written in English. Methodological quality was assessed using the AXIS tool. RESULTS: 462 articles were screened, and 7 papers included for data extraction, which collectively assessed the confidence of 956 doctors working in EDs in managing ophthalmic emergencies. There was a widespread lack of confidence amongst foundation doctors, which has worsened over time. Most doctors lacked confidence in performing funduscopy and using the slit-lamp, and considered formal ophthalmology training received in EDs to be inadequate. CONCLUSIONS: Evidence suggests a lack of confidence amongst foundation doctors in managing ophthalmic emergencies. High-quality evidence investigating the confidence amongst more experienced Emergency Medicine (EM) physicians was lacking. It is important to assess why foundation doctors feel so ill-prepared to manage eye emergencies and develop further ophthalmic training for doctors working in EDs. Further investigation exploring the confidence of EM trainees and consultants is required.

RESUMEN

The goal of this study was to compare operative outcomes after lesser toe deformity correction with either proximal interphalangeal (PIP) joint arthrodesis or PIP joint resection arthroplasty. A prospective randomized controlled trial was performed with 37 patients (48 toes) operated on with one of these two procedures. Evaluation of the numeric rating scale score, the American Orthopedic Foot and Ankle Society score, osseous consolidation, and clinical outcome was performed preoperatively and at 6 weeks and 6 months postoperatively. Both study groups showed significant improvement at 6 months postoperatively. Although osseous consolidation was significantly higher for the arthrodesis group (P=.001), this difference did not affect clinical outcomes, and at 6 months postoperatively, pain on the numeric rating scale was 0 (range, 0-7) for the arthroplasty group and 0 (range, 0-5) for the arthrodesis group (P=.669). The American Orthopedic Foot and Ankle Society score was 83 (range, 39-95) and 80 (range, 59-95), respectively (P=.879). No difference was observed for signs of inflammation or axis correction. Even a direct comparison of toes with radiologically osseous fusion (n=16) with those without fusion (n=32) did not show any clinical differences. This randomized controlled study showed no clinical differences in outcome between PIP joint arthrodesis and PIP joint resection arthroplasty for correction of lesser toe deformities, with good to excellent outcomes for both groups.

RESUMEN

INTRODUCTION: To establish the level of confidence amongst UK ophthalmology specialist registrars (residents) in managing posterior capsule rupture (PCR) during cataract surgery. METHODS: An online nine-item questionnaire was distributed to all registrars, recruited nationwide via regional representatives. Data collected included stage of training, number of completed cataract operations, cumulative PCR rate, number of PCRs independently managed, understanding of vitrectomy settings and fluidic parameters and access to simulation. Respondents self-evaluated their confidence in managing PCR with vitreous loss. RESULTS: Complete responses were obtained from 248 registrars (35% response rate). Mean number of phacoemulsification procedures performed was 386. For senior registrars (OST 6-7), 35 out of 70 (50%) felt confident to manage PCR independently and 55 out of 70 (78.6%) were either quite confident or very confident at deciding when to implant an intraocular lens during PCR management. Lower confidence levels were noted for junior trainees (OST 1-2). Over 65% of survey respondents had access to relevant simulation. CONCLUSIONS: Our results represent the largest UK survey analysing the confidence of PCR management amongst registrars. Confidence improves with duration of training and increased exposure to management of PCR. However, 50% of senior registrars still lacked confidence to independently manage PCR and vitreous loss. A specific competency-based framework, potentially using a simulator or simulating a PCR event, incorporated into the curriculum may be desirable.

RESUMEN

Optogenetics is a novel technique of delivering genes that encode proteins capable of conveying light sensitivity to neurons, heralding exciting new possibilities for laboratory-based neuroscience research. This fast-developing field is of particular interest because of the potential application for individualised diagnostic and therapeutic clinical approaches. The authors describe what optogenetics is and how it works, explain its significance to neurosurgery and illustrate its relevance by giving examples of recent translational and future clinical applications.

RESUMEN

To investigate cerebrospinal fluid (CSF) leak rates after mainly endoscopic endonasal transsphenoidal surgery with and without polyethylene glycol hydrogel dural sealant (DuraSeal®), we prospectively collected data from a single-centre consecutive case series over four years from January 2007 to December 2010 inclusive. 250 patients were identified (135 male, 115 female; median age 52years, range 14-83). 180 patients received DuraSeal® (72%). 85 (34%) had intra-operative dural breach and 13 (5.2%) developed post-operative CSF leaks (3 without intra-operative dural breach) requiring lumbar drainage or formal repair. Of this group 5/251 (2.0%) patients required a formal repair. Post-operative CSF leak was seen in 5/189 (2.7%) of patients with pituitary adenoma, of which 2/5 (40%) were in cases undergoing revision surgery. 5/13 (38.4%) patients who developed a CSF leak presented with either Rathke's cleft cyst or craniopharyngioma. 3/71 patients not receiving DuraSeal® leaked (4.2%) and 10/180 patients receiving DuraSeal® leaked (5.6%). 11/234 patients without Tisseel (4.7%) and 2/16 receiving Tisseel (12.5%) leaked. 54 patients (22%) received intra-operative lumbar drains, one of whom developed subsequent CSF leak (1.9%), in contrast to 12/197 (6.1%) of patients without intra-operative lumbar drains who later developed CSF leak. The rate of post-operative CSF leak requiring re-exploration and nasoseptal flap repair was low (2.0%) in this mainly endoscopic case series without statistically significant benefit from either DuraSeal® or Tisseel. Intra-operative and post-operative lumbar drainage appears beneficial in patients at higher risk of post-operative CSF leak.

RESUMEN

INTRODUCTION: The aim of this study was to determine treatment delivery patterns for patients with neovascular age-related macular degeneration (nAMD) across the UK through an ophthalmology trainee research network delivered observational study. METHODS: Data were collected via an online tool by potential research collaborators identified by the Ophthalmology Trainee Clinical Trial Network (OCTN). Collaborators were asked to comment on periprocedural practices of treatment of nAMD in their eye unit including treatment location and injectors, clinical assessment and routine observation in patients undergoing intravitreal treatment. RESULTS: Data were available from 26 units around the United Kingdom. Survey methodology refinement was approximately 3 months, and the average response time was 4.9 ± 2.4 days. The majority of responders confirmed that treatment was undertaken as a "one-stop" service (n = 15, 58%), delivered in a clean room (n = 23, 88%). In the majority of units, doctors administered injections (n = 24, 92%), but significant treatment was also given by nurse injectors (n = 21, 81%). All collaborators reported that patients underwent visual acuity testing and optical coherence tomography imaging at all visits, but other imaging including fundus fluorescein angiography (FFA) did not take place in all cases (n = 17, 65%) and only at baseline visit. CONCLUSIONS: These results demonstrate the feasibility of conducting ophthalmology trainee led and delivered observational studies. Our results show that FFA is not routinely used in the diagnosis of nAMD in the units sampled; most injections are carried out in a clean room, and ophthalmic nurses delivering injections is a highly prevalent model of care in the UK.

RESUMEN

Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations of reinforcement value and response costs. Furthermore, people with major depression and other disorders often show anergia, psychomotor retardation, fatigue, and alterations in effort-related decision making. Tasks measuring effort-based decision making can be used as animal models of the motivational symptoms of depression, and the present studies characterized the effort-related effects of the vesicular monoamine transport (VMAT-2) inhibitor tetrabenazine. Tetrabenazine induces depressive symptoms in humans, and also preferentially depletes dopamine (DA). Rats were assessed using a concurrent progressive ratio (PROG)/chow feeding task, in which they can either lever press on a PROG schedule for preferred high-carbohydrate food, or approach and consume a less-preferred lab chow that is freely available in the chamber. Previous work has shown that the DA antagonist haloperidol reduced PROG work output on this task, but did not reduce chow intake, effects that differed substantially from those of reinforcer devaluation or appetite suppressant drugs. The present work demonstrated that tetrabenazine produced an effort-related shift in responding on the PROG/chow procedure, reducing lever presses, highest ratio achieved and time spent responding, but not reducing chow intake. Similar effects were produced by administration of the subtype selective DA antagonists ecopipam (D1) and eticlopride (D2), but not by the cannabinoid CB1 receptor neutral antagonist and putative appetite suppressant AM 4413, which suppressed both lever pressing and chow intake. The adenosine A2A antagonist MSX-3, the antidepressant and catecholamine uptake inhibitor bupropion, and the MAO-B inhibitor deprenyl, all reversed the impairments induced by tetrabenazine. This work demonstrates the potential utility of the PROG/chow procedure as a rodent model of the effort-related deficits observed in depressed patients.
