To determine corneal Q value and its related factors in Chinese subjects older than 30 years. Cross sectional study. 1,683 participants (1,683 eyes) from the Handan Eye Study were involved, including 955 female and 728 male with average age of 53.64 years old (range from 30 to 107 years). The corneal Q values of anterior and posterior surfaces were measured at 3.0, 5.0 and 7.0mm aperture diameters using Bausch & Lomb Orbscan IIz (software version 3.12). Age, gender and refractive power were recorded. The average Q values of the anterior surface at 3.0, 5.0 and 7.0mm aperture diameters were -0.28±0.18, -0.28±0.18, and -0.29±0.18, respectively. The average Q value of the anterior surface at the 5.0mm aperture diameter was negatively correlated with age (B = -0.003, p<0.01) and the refractive power (B = -0.013, p = 0.016). The average Q values of the posterior surface at 3.0, 5.0, and 7.0mm were -0.26±0.216, -0.26±0.214, and -0.26±0.215, respectively. The average Q value of the posterior surface at the 5.0mm aperture diameter was positively correlated with age (B = 0.002, p = 0.036) and the refractive power (B = 0.016, p = 0.043). The corneal Q value of the elderly Chinese subjects is different from that of previously reported European and American subjects, and the Q value appears to be correlated with age and refractive power.

Background This study evaluates patients with congenital aniridia and cataract who underwent phacoemulsification, capsular tension ring placement, and foldable intraocular lens implantation. Methods In this prospective case series, 10 patients (17 eyes) underwent cataract surgery via a 3.2 mm clear corneal incision. A continuous circular capsulorhexis with <6 mm diameter was employed. A capsular tension ring and HOYA yellow foldable posterior chamber intraocular lens was implanted. All patients wore color contact lenses postoperatively. Paired t test was used to compare visual acuity, intraocular pressure, and corneal endothelial changes before and after surgery. Results A single surgeon performed all surgeries. The best-corrected visual acuity improved from value 1.03 ± 0.27LogMAR preoperatively to value 0.78 ± 0.26LogMAR postoperatively ( p  = 0.000). The photophobic symptoms improved significantly after surgery. The mean corneal endothelial cell density before and after surgery was 3280 ± 473 cells/mm2 and 2669 ± 850 cells/mm2, respectively ( p  = 0.006). None of the patients developed corneal endothelial decompensation or secondary glaucoma after surgery. Conclusions Treatment of congenital aniridia and coexistent cataract by phacoemulsification, posterior chamber foldable lens implantation, capsular tension ring placement was safe and effective. Use of colored contact lenses in the postoperative period can reduce photophobic symptoms in this group of patients.

Purpose To report the 1-year outcomes of every-4-weeks (Q4W) as-needed aflibercept treatment in resistant neovascular age-related macular degeneration (nAMD) patients who had been treated and failed prior bevacizumab or ranibizumab injections, and who also responded poorly to every-8-weeks (Q8W) aflibercept treatment. Methods Forty-three eyes of 39 patients with persistent nAMD despite monthly bevacizumab and/or ranibizumab injections and who were switched to Q8W 2-mg aflibercept injections, but showed persistence of fluid were included. Patients were treated with as-needed Q4W aflibercept injections with monthly monitoring. Maximum retinal thickness (MRT), central macular thickness (CMT), maximum pigment epithelial detachment height (PED) and best-corrected visual acuity (BCVA) were assessed and compared to baseline when high-frequency aflibercept was initiated. Results A mean of 8 (interquartile range, 4–11) Q4W injections were given during the follow-up. MRT and CMT significantly decreased at all follow-up visits ( p  < 0.05); however, there was no significant change in maximum PED height ( p  > 0.05) at any visit. Mean BCVA was 0.38 ± 0.28 (logMAR) (≈20/63, Snellen) at baseline, and 0.4 ± 0.34 (logMAR) (≈20/76, Snellen) at 1 year ( p  = 0.76). Seventy-two percent of eyes maintained a final BCVA of 20/63 or better. Twelve eyes (28 %) had some subretinal scar tissue formation and 5 eyes (11.6 %) had evidence of atrophy at 1 year. Conclusion A stepwise algorithm with Q4W as-needed aflibercept treatment led to anatomic improvement in previously treated eyes which failed other therapies, including aflibercept every 8 weeks. Lack of visual improvement may be due to a ceiling effect as our eyes generally had good visual acuity.

To report the outcomes of decanted high-dose intravitreal triamcinolone acetonide (HD-IVTA) injection for treatment-resistant persistent macular edema (ME). Seventy-seven eyes of 70 consecutive patients who failed prior treatments for persistent ME received as-needed HD-IVTA injections. Best-corrected visual acuity and central macular thickness (CMT) were assessed at all follow-up visits. Thirty-three eyes (42.8%) had ME following pars plana vitrectomy. The mean ETDRS letter score from baseline improved by 6.3 letters ± 11.5 letters at 3 months (P < .001) and 4.8 letters ± 11.4 letters at 12 months (P = .016). The mean change in CMT from baseline was significant at all follow-up visits (P < .001). During 1-year follow-up, 49 eyes (63.6%) required only one HD-IVTA injection. The mean time for reinjection was 6 months ± 2.4 months (range: 1.6 months to 10.5 months) after the first injection of HD-IVTA. The incidence of elevated intraocular pressure was 40.2% (31 of 77 eyes). Of these, one eye required glaucoma surgery. Among 14 phakic eyes, 21.4% (three eyes) developed cataract formation requiring surgery. A single HD-IVTA injection can provide a long duration of effect on ME of up to 6 months.

The purpose of the present study was to analyze the clinical phenotypes of a girl with oculo-facio-cardio-dental (OFCD) syndrome and to identify the potential pathogenic mutation responsible for her disease. The patient underwent detailed clinical examinations and phenotype data were collected over a follow-up period of 9 years. Mutation analysis of the candidate gene BCOR was performed with polymerase chain reaction and Sanger sequencing. BCOR of 60 unrelated normal individuals were also sequenced as a control group. Clinical phenotyping and follow-up study results indicate that this patient had multiple system anomalies including ocular, facial, cardiac, dental, and limb malformations. In addition, papilloma of the choroid plexus was identified, which represents the first report of this phenotype in an OFCD patient. A novel deletion mutation, c.1296delT in exon 4 of the BCOR gene, was identified in this patient and was not found in her parents or in 60 normal unrelated individuals. This deletion was a frameshift mutation and is proposed to encode a premature stop codon, thus producing a truncated protein. Our patient fitted the diagnostic criteria for OFCD syndrome and we report the first papilloma of the choroid plexus in an OFCD patient, expanding the recognized phenotypic spectrum of this disease. Meanwhile, we identified a novel deletion mutation that may cause OFCD syndrome.

Abstract The prevalence of obesity, measured by body mass index, has risen to unacceptable levels in both men and women in the United States and worldwide with resultant hazardous health implications. Genetic, environmental, and behavioral factors influence the development of obesity, and both the general public and health professionals stigmatize those who suffer from the disease. Obesity is associated with and contributes to a shortened life span, type 2 diabetes mellitus, cardiovascular disease, some cancers, kidney disease, obstructive sleep apnea, gout, osteoarthritis, and hepatobiliary disease, among others. Weight loss reduces all of these diseases in a dose-related manner-the more weight lost, the better the outcome. The phenotype of \"medically healthy obesity\" appears to be a transient state that progresses over time to an unhealthy phenotype, especially in children and adolescents. Weight loss is best achieved by reducing energy intake and increasing energy expenditure. Programs that are effective for weight loss include peer-reviewed and approved lifestyle modification programs, diets, commercial weight-loss programs, exercise programs, medications, and surgery. Over-the-counter herbal preparations that some patients use to treat obesity have limited, if any, data documenting their efficacy or safety, and there are few regulatory requirements. Weight regain is expected in all patients, especially when treatment is discontinued. When making treatment decisions, clinicians should consider body fat distribution and individual health risks in addition to body mass index. This Scientific Statement critically reviews the definition of obesity, providing a list of assessment methods, obesity-related diseases, and prevention measures.

Recent studies raised concerns about the increasing use of gabapentinoids in different countries. With their potential for misuse and addiction, understanding the global consumption of gabapentinoids will offer us a platform to examine the need for any interventional policies. This longitudinal trend study utilised pharmaceutical sales data from 65 countries and regions across the world to evaluate the global trends in gabapentinoid consumption between 2008-2018. The multinational average annual percentage change of gabapentinoid consumption was +17.20%, increased from 4.17 defined daily dose per ten thousand inhabitants per day (DDD/TID) in 2008 to 18.26 DDD/TID in 2018. High-income countries had the highest pooled gabapentinoid consumption rate (39.92 DDD/TID) in 2018, which was more than six times higher than the lower-middle income countries (6.11 DDD/TID). The study shows that despite differences in healthcare system and culture, a consistent increase in gabapentinoid consumption is observed worldwide, with high-income countries remaining the largest consumers. With their misuse potential, there is a need to understand the global consumption of gabapentinoids. Here, authors show a + 17.20% worldwide average annual increase in consumption of gabapentinoids from 2008 to 2018.

Osimertinib (AZD9291) is an oral, potent, irreversible EGFR tyrosine-kinase inhibitor selective for EGFR tyrosine-kinase inhibitor sensitising mutations, and the EGFR Thr790Met resistance mutation. We assessed the efficacy and safety of osimertinib in patients with EGFR Thr790Met-positive non-small-cell lung cancer (NSCLC), who had progressed after previous therapy with an approved EGFR tyrosine-kinase inhibitor. In this phase 2, open-label, single-arm study (AURA2), patients aged at least 18 years with centrally confirmed EGFR Thr790Met-positive mutations, locally advanced or metastatic (stage IIIB/IV) NSCLC who progressed on previous EGFR tyrosine-kinase inhibitor therapy received osimertinib 80 mg orally once daily; treatment could continue beyond progression if the investigator observed a clinical benefit. Patients with asymptomatic, stable CNS metastases not requiring steroids were allowed to enrol. The primary endpoint was the proportion of patients achieving an objective response by blinded independent central review using Response Evaluation Criteria in Solid Tumors, version 1.1. Response endpoints were assessed in the evaluable for response analysis set (ie, all patients who received at least one dose of osimertinib and had measurable disease at baseline according to blinded independent central review). Other endpoints and safety were assessed in all patients receiving at least one osimertinib dose (full analysis set). The study is ongoing and patients are still receiving treatment. This study is registered with ClinicalTrials.gov, number NCT02094261. Between May 20, 2014, and Sept 12, 2014, 472 patients were screened, of whom 210 started osimertinib treatment between June 13, 2014, and Oct 27, 2014; 11 patients were excluded from the evaluable for response analysis set (n=199) due to absence of measurable disease at baseline by blinded independent central review. At data cutoff (Nov 1, 2015), 122 (58%) patients remained on treatment. The median duration of follow-up was 13·0 months (IQR 7·6–14·2). 140 (70%; 95% CI 64–77) of 199 patients achieved an objective response by blinded independent central review: confirmed complete responses were achieved in six (3%) patients and partial responses were achieved in 134 (67%) patients. The most common all-causality grade 3 and 4 adverse events were pulmonary embolism (seven [3%]), prolonged electrocardiogram QT (five [2%]), decreased neutrophil count (four [2%]), anaemia, dyspnoea, hyponatraemia, increased alanine aminotransferase, and thrombocytopenia (three [1%] each). Serious adverse events were reported in 52 (25%) patients, of which 11 (5%) were investigator assessed as possibly treatment-related to osimertinib. Seven deaths were due to adverse events; these were pneumonia (n=2), pneumonia aspiration (n=1), rectal haemorrhage (n=1), dyspnoea (n=1), failure to thrive (n=1), and interstitial lung disease (n=1). The only fatal event assessed as possibly treatment-related by the investigator was due to interstitial lung disease. Osimertinib showed clinical activity with manageable side-effects in patients with EGFR Thr790Met-positive NSCLC. Therefore, osimertinib could be a suitable treatment for patients with EGFR Thr790Met-positive disease who have progressed on an EGFR tyrosine-kinase inhibitor. AstraZeneca.
