Survey of Intraocular Antibiotics Prophylaxis Practice after Open Globe Injury in China.

ABSTRACT: To elucidate the Chinese practice of intraocular antibiotics administration for prophylaxis after open globe injury.A cross-sectional questionnaire survey was performed online by scanning a Quickmark (QR) code with smartphones at the 20th Chinese National Conference of Ocular Trauma in November 2014.A total of 153 (30.6%) of all participators at the conference responded. Of the respondents, 20.9% were routinely administered with prophylactic intraocular injection of antibiotics at the conclusion of the primary eye repair, and 56.9% were used only in cases with high risk of endophthalmitis development. The intraocular route of delivery was mainly included with intracameral injection (47.9%) and intravitreal injection (42.0%). Cephalosporins (53.8%) and vancomycin (42.0%) were the main choices of antibiotic agents, followed by fluoroquinolones (24.3%), and aminoglycosides (13.4%). Only 21.9% preferred a combination of two or more two drugs routinely. In addition, significantly more respondents from the referral eye hospital (92.7%) replied using intraocular antibiotics injection for prophylaxis compared to those respondents from the primary hospital (69.4%) (p = 0.001, Fisher's exact test).Intraocular antibiotics injection for post-traumatic endophthalmitis prophylaxis is widely used in China. However, the choice of antibiotic agents and the intraocular route of delivery vary. A well-designed clinical trial is needed to establish a standardized protocol of intraocular antibiotics administration for post-traumatic endophthalmitis prophylaxis.

Project description:BackgroundThe prognostic significance of debridement has long been demonstrated for trauma in tissues other than ocular. Unfortunately, the impact of wound healing in the anterior segment (AS) was not paid as much attention as in the posterior segment (PS). This study aims to evaluate whether a better prognosis can be obtained from continuous surgical treatment (CST) before fibrosis or scar formation in an open AS injury.MethodsIn this prospective comparative cohort study, 19 eyes of 19 patients with an experience of AS open globe injury (OGI) were selected from the database of the eye injury vitrectomy study (EIVS) from January 1, 2020 to July 31, 2021. Of 19 patients, 9 who received CST were assigned to group 1, and 10 patients without CST after the initial wound repair were included in group 2. Comparison between the two groups was conducted in the final best corrected visual acuity (BCVA). Significant AS complications after injury were evaluated with χ2 test. The corneal leucoma area ratio, astigmatism, and the score of AS abnormalities were analyzed using the Student's t-test.ResultsThe differences of baseline clinical factors between the two groups were not statistically significant. The final BCVA was better in group 1 than in group 2 (P=0.011). The complications directly caused by AS injury, namely adhesive corneal leucoma, uneven anterior chamber, block of light passing through the pupil, and fibrosis or scarring, were more frequent in group 2 than in group 1 (P=0.011, 0.022, 0.037, and 0.040, respectively). Secondary glaucoma (3 cases) and severe AS structure destruction (2 cases) occurred only in group 2 (P=0.037 and 0.474, respectively). The area ratio of leucoma (0.79±0.44, 0.82±0.50, respectively) and corneal astigmatism (3.69±1.90, 4.50±4.80, respectively) revealed no statistical significance between the two groups. On the other hand, the score of AS abnormalities, mean values being 93.33±11.18 for group 1 and 67.00±29.46 for group 2, was statistically different (P=0.022).ConclusionsInitiating CST before fibrosis or scar formation might improve the prognosis of open AS injury, which was preferable to natural wound healing after wound repair.

Project description:PurposeTo evaluate the effects of intravitreal anti-VEGF agents in a rabbit model of open-globe injury (OGI).MethodsOGI was induced in the right eyes of 75 Belgian rabbits by making 5 mm circumferential incision placed 6 mm behind the limbus. The rabbits were divided into 4 groups: control (n = 5), OGI group (n = 40), and intravitreal Ranibizumab and Conbercept (n = 15 each). Ranibizumab or Conbercept was injected into the vitreous at 0.5 hours, 3 days, or 7 days. Vitreous fluid was collected, and levels of growth factors and cytokines were measured by enzyme-linked immunosorbent assay (ELISA). On day 28 after OGI, B scan examination and histological examination were performed to evaluate intravitreal proliferation and formation of epiretinal fibrosis.ResultsVitreous levels of vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), and plasminogen activator inhibitor-1 (PAI-1) were significantly increased in rabbit eyes after OGI. Compared to eyes in OGI group, anti-VEGF treatments significantly reduced these growth factors and cytokines. Among the 7 eyes examined from each group for intravitreal proliferative changes, they were found in 7 of 7 (100%) in OGI group and were decreased by Ranibizumab and Conbercept to 5 of 7 (71.4%) and 4 of 7 (57.1%), respectively. Both Ranibizumab and Conbercept inhibited epiretinal scar formation at the wound site, with Conbercept showing the greatest effect (maximal length of scar (L), L OGI = 503 ± 82.44 μm, L Ranibizumab = 355 ± 43.66 μm, and L Conbercept = 250.33 ± 36.02 μm).ConclusionAnti-VEGF treatments after OGI significantly attenuated the upregulation of growth factors and cytokines in the vitreous and prevented intravitreal proliferation and epiretinal scar formation and thus may protect against the development of posttraumatic complications such as proliferative vitreoretinopathy (PVR).

Project description:PurposeTo estimate incidence and evaluate demographic risk factors and visual acuity (VA) outcomes of open-globe injuries requiring surgical repair in the IRIS® Registry (Intelligent Research in Sight).DesignRetrospective cohort study.ParticipantsPatients with open-globe injury repairs (OGRs) were identified by Current Procedural Terminology codes (65275, 65280, 65285, 65286, 65235, 65260, and 65265) from 2014 through 2018 in the IRIS Registry.MethodsLogistic regression models adjusting for age, sex, race, ethnicity, United States region, concurrent and subsequent surgeries, and baseline VA.Main outcome measuresOutcomes included annual and 5-year incidence rates per 100 000 people and factors associated with OGR, VA better than 20/40, and VA of 20/200 or worse at final follow-up (3-12 months after OGR).ResultsThirteen thousand seven hundred sixty-six OGRs were identified; 5-year cumulative incidence was 28.0 per 100 000 patients. Open-globe repair was associated with age 21 to 40 years compared with younger than 21 years (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.5-1.7]), male sex (OR, 2.8; 95% CI, 2.7-2.9), Black versus White race (OR, 1.3; 95% CI, 1.2-1.4), Hispanic versus non-Hispanic ethnicity (OR, 1.7; 95% CI, 1.6-1.8), and South (OR, 1.4; 95% CI, 1.3-1.5) and West (OR, 1.3; 95% CI, 1.2-1.4) versus Midwest regions and associated inversely with Asian versus White race (OR, 0.6; 95% CI, 0.6-0.7). Visual acuity outcomes, analyzed in a subset of 2966 patients with VA data available, showed vision impairment (VA < 20/40) at final follow-up was associated with VA of 20/200 or worse at presentation (20/200 better than 20/40; OR, 11.1; 95% CI, 8.0-15.7), older age (e.g., > 80 years vs. < 21 years; OR, 5.8; 95% CI, 3.2-10.7), and Black versus White race (OR, 1.8; 95% CI, 1.3-2.6). Risk factors were similar for VA of 20/200 or worse after OGR. Among the 1063 patients undergoing OGR with VA of 20/200 or worse at presentation, VA did not improve to better than 20/200 at follow-up in 35% of patients (1063/2996).ConclusionsOur findings bring to light racial disparities in risk of OGR and poor visual outcomes that warrant further exploration.Financial disclosure(s)Proprietary or commercial disclosure may be found after the references.

Project description:Proper diagnosis and treatment of traumatic brain injury (TBI) in children is becoming an increasingly problematic issue in China. This study investigated Chinese clinicians to provide information about their knowledge and experiences in diagnosis and treatment of pediatric TBI. We conducted a questionnaire survey among clinicians in the emergency departments and neurosurgery departments at 9 major hospitals in China. The questionnaire included demographic information, and knowledge and experiences regarding the diagnosis and treatment of pediatric TBI. A total of 235 clinicians completed questionnaires. 43.8% of the surveyed clinicians reported children with only scalp hematoma without any other signs and symptoms of concussion as TBI cases. Most clinicians (85.1%) reported no existing uniform diagnostic criteria for children with TBI in China. The majority of clinicians (91.9%) reported that CT scans were performed in all patients with suspected head injury as a routine procedure in their hospitals. Only 20.9% of clinicians believed that radiation from CT scanning may increase cancer risk in children. About 33.6% of the clinicians reported that they ordered CT scans to investigate suspected head injury due to the poor doctor-patient relationship in China, and to protect themselves against any medical lawsuits in the future. About 80% of the clinicians reported that there are no existing pediatric TBI treatment guidelines in China. Instead a senior doctor's advice is the most reported guidelines regarding treating pediatric TBI (66.0%). All of the surveyed clinicians reported that the lack of diagnosis and/or treatment standard is the biggest problem in effectively diagnosing and treating pediatric TBI in China. Developing guidelines for the diagnosis and treatment of children with TBI is a high priority in China. The extremely high usage of CT for pediatric TBI in China suggests that it is important to establish evidence-based clinical decision rules to help Chinese clinicians make diagnostic and therapeutic decisions during their practice in order to identify children unlikely to have a clinically-important TBI who can be safely discharged without a CT scan.

Project description:ObjectiveTo measure knowledge, attitude and practice of antibiotics and antibiotic resistance (ABR) and their determinants in the Eritrean urban population.DesignA population-based, nation-wide, cross-sectional study.SettingUrban settings of Eritrea.ParticipantsMembers of the general public aged ≥18 years and living in 13 urban places of Eritrea. Three-stage stratified cluster sampling was used to select the study participants.Data collection and analysisDate were collected from July 2019 to September 2019 in a face-to-face interview using a structured questionnaire. The collected data were double entered and analysed using Census and Survey Processing system (V.7.0) and SPSS (V.23), respectively. Descriptive statistics, χ2 test, t-tests, analysis of variance, factorial analysis and multivariable logistic regression were performed. All analyses were weighted and p<0.05 was considered significant.Primary and secondary outcome measuresMain outcome variables were knowledge, attitude and practice of antibiotics and ABR. Secondary outcome measure was the determinants of knowledge, attitude and practice.ResultsA total of 2477 adults were interviewed. The mean score of knowledge and attitude of antibiotics and ABR was 10.36/20 (SD=3.51, minimum=0 and maximum=20) and 22.34/30 (SD=3.59, minimum=6 and maximum=30), respectively. Of those who used antibiotics, the proportion of at least one inappropriate practice (use of antibiotics without prescription and/or discontinuation of prescribed antibiotics before completing the full course) was 23.8%. Young age <24 years (adjusted odds ratio (AOR)=1.61, 95% CI: 1.08 to 2.41), male sex (AOR=1.48, 95% CI: 1.14 to 1.91), higher level of education (AOR=1.76, 95% CI: 1.08 to 2.88), and negative attitude towards appropriate use of antibiotics (AOR=0.95, 95% CI: 0.92 to 0.97) were found to be the significant determinants of inappropriate practice of antibiotics.ConclusionThe gap in knowledge and inappropriate practice of antibiotics in the Eritrean urban population was widespread; requiring immediate attention from policy-makers and healthcare professionals.
