Embolization of percutaneous left atrial appendage closure devices: timing, management and clinical outcomes.

BACKGROUND: Left atrial appendage (LAA) occluder embolization is an infrequent but serious complication. OBJECTIVES: We aim to describe timing, management and clinical outcomes of device embolization in a multi-center registry. METHODS: Patient characteristics, imaging findings and procedure and follow-up data were collected retrospectively. Device embolizations were categorized according to 1) timing 2) management and 3) clinical outcomes. RESULTS: Sixty-seven centers contributed data. Device embolization occurred in 108 patients. In 70.4 % of cases, it happened within the first 24 h of the procedure. The device was purposefully left in the LA and the aorta in two (1.9 %) patients, an initial percutaneous retrieval was attempted in 81 (75.0 %) and surgery without prior percutaneous retrieval attempt was performed in 23 (21.3 %) patients. Two patients died before a retrieval attempt could be made. In 28/81 (34.6 %) patients with an initial percutaneous retrieval attempt a second, additional attempt was performed, which was associated with a high mortality (death in patients with one attempt: 2.9 % vs. second attempt: 21.4 %, p < 0.001). The primary outcome (bailout surgery, cardiogenic shock, stroke, TIA, and/or death) occurred in 47 (43.5 %) patients. Other major complications related to device embolization occurred in 21 (19.4 %) patients. CONCLUSIONS: The majority of device embolizations after LAA closure occurs early. A percutaneous approach is often the preferred method for a first rescue attempt. Major adverse event rates, including death, are high particularly if the first retrieval attempt was unsuccessful. CONDENSED ABSTRACT: This dedicated multicenter registry examined timing, management, and clinical outcome of device embolization. Early embolization (70.4 %) was most frequent. As a first rescue attempt, percutaneous retrieval was preferred in 75.0 %, followed by surgical removal (21.3 %). In patients with a second retrieval attempt a higher mortality (death first attempt: 2.9 % vs. death second attempt: 24.1 %, p < 0.001) was observed. Mortality (10.2 %) and the major complication rate after device embolization were high.

Prognostic impact of cardiohepatic syndrome in patients with ST-segment elevation myocardial infarction.

Background: Cardiohepatic syndrome (CHS) indicates a bidirectional interaction between the heart and liver. This study was designed to evaluate the impact of CHS on in-hospital and long-term mortality in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention. Materials & methods: 1541 consecutive STEMI patients were examined. CHS was defined as the elevation of at least two of three cholestatic liver enzymes: total bilirubin, alkaline phosphatase and gamma-glutamyl transferase. Results: CHS was present in 144 (9.34%) patients. Multivariate analyses revealed CHS as an independent predictor of in-hospital (odds ratio: 2.48; 95% CI: 1.42-4.34; p = 0.001) and long-term mortality (hazard ratio: 2.4; 95% CI: 1.79-3.22; p < 0.001). Conclusion: The presence of CHS is a predictor of poor prognosis in patients with STEMI and should be evaluated during the risk stratification of these patients.

Assessment of the relationship between monocyte to high-density lipoprotein ratio and subclavian artery stenosis.

OBJECTIVE: Assessment of the monocyte-to-high-density lipoprotein ratio (MHR) is a new tool for predicting inflammation, which plays a major role in atherosclerosis. Subclavian artery stenosis (SAS) is usually asymptomatic, and atherosclerosis is the most common cause of chronic obstruction of the subclavian artery in adults. The aim of this study was to determine the relationship between the MHR and SAS. PATIENTS AND METHODS: Between January 2015 and January 2020, 43 patients with SAS and 43 patients without SAS were enrolled in the study. The patients' angiographic, demographic and clinic characteristics were reviewed from their medical records. Monocytes and HDL (high-density lipoprotein) cholesterols were measured through a complete blood count. The MHR was calculated as the ratio of the absolute monocyte count to the HDL cholesterol value. The resulting MHR values were divided into the following three groups: low (7.16 ± 1.59), moderate (11.08 ± 1.53) and high (21.70 ± 5.62). A p-value of less than 0.05 was considered significant. RESULTS: MHR was found to be significantly higher in the SAS group compared to the control group with normal subclavian arteries (p<0.001). The frequency of SAS was found to increase with an increase in the MHR tertiles. Sensitivity and specificity values were 69.8% and 95.3%, respectively. The cut-off of the MHR value, taken as 13.39, was found to provide a significantly accurate prediction of the subclavian diagnosis (ROC area under the curve: 0.868, 95% CI: 0.789-0.947, p<0.001). After adjusting for other hematological parameters in the multivariate analysis, MHR (p=0.061) was found to be a predictor of the presence of SAS. CONCLUSIONS: This study showed that MHR can be a convenient marker for predicting SAS because of the correlation between MHR and SAS.

CRISPR-Cas12-based field-deployable system for rapid detection of synthetic DNA sequence of the monkeypox virus genome.

The global outbreak of the monkeypox virus (MPXV) highlights the need for rapid and cost-effective MPXV detection tools to effectively monitor and control the monkeypox disease. Herein, we demonstrated a portable CRISPR-Cas-based system for naked-eye detection of MPXV. The system harnesses the high selectivity of CRISPR-Cas12 and the isothermal nucleic acid amplification potential of recombinase polymerase amplification. It can detect both the current circulating MPXV clade and the original clades. We reached a limit of detection (LoD) of 22.4 aM (13.5 copies/µl) using a microtiter plate reader, while the visual LoD of the system is 75 aM (45 copies/µl) in a two-step assay, which is further reduced to 25 aM (15 copies/µl) in a one-pot system. We compared our results with quantitative polymerase chain reaction and obtained satisfactory consistency. For clinical application, we demonstrated a sensitive and precise visual detection method with attomolar sensitivity and a sample-to-answer time of 35 min.

Is thyroid-stimulating hormone a predictor of severity of carotid artery disease?

OBJECTIVE: The relationship between thyroid function and carotid artery stenosis in euthyroid patients is controversial. Therefore, we aimed at evaluating the relationship between the severity of carotid artery disease (CAD) and thyroid-stimulating hormone (TSH) levels in euthyroid patients. PATIENTS AND METHODS: A total of 90 euthyroid patients with CAD were trichotomized into three groups based on CAD severity. Group 1 comprised patients who had one internal carotid artery with total stenosis and the other with more than 50% stenosis. In Group 2, patients had one internal carotid artery with total stenosis and the other with less than 50% stenosis. Group 3 comprised patients with less than 50% stenosis in both internal carotid arteries. Demographic data, complete blood count, biochemical parameters, and thyroid function parameters were compared between the groups. RESULTS: No significant relationship was noted between the severity of CAD and demographic data and comorbidity rates. A comparison of the biochemical parameters revealed that TSH levels were significantly different between the groups. Post-hoc analysis showed that Group 1 and Group 3 differed significantly with respect to TSH levels (0.75 ± 0.37 IU/mL vs. 1.39 ± 1.00 IU/mL, p=0.002). A cut-off value of 0.65 yielded 46.67% sensitivity and 81.67% specificity, whereas a cut-off value of 0.70 yielded 53.33% sensitivity and 75.00% specificity. The area under the curve was 0.691 (95% CI, 0.576-0.806) (p=0.003). CONCLUSIONS: TSH can be demonstrated to predict severe carotid artery disease. Therefore, the severity of CAD can be assessed using TSH levels.

Performance of the Academic Research Consortium High Bleeding Risk Criteria in Patients With ST-Segment Elevation Myocardial Infarction: A Single Center Study.

We assessed the ability of predicting mortality and total in-hospital bleeding and adverse outcomes by the Academic Research Consortium High Bleeding Risk (ARC-HBR) criteria in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). A total of 1441 STEMI patients were recruited: HBR group 354 (25%) patients and non-HBR group of 1087 (75%) patients. A total of 131 patients (9%) had a bleeding complication during hospitalization. The bleeding complications were also categorized according to other conventional bleeding scores. According to these conventional scores, all bleeding categories were associated with HBR. In univariate logistic regression analysis, female gender, diabetes mellitus, hypertension (HT) and HBR were associated with in-hospital bleeding. However, in multivariable analysis only HT (Odds Ratio [OR] 1.528, 95% CI 1.020-2.290; P = .040) and HBR (OR 1.612, 95% CI 1.075-2.428; P = .022) independently predicted total in-hospital bleeding complications. Hospital duration was longer and mortality rate was significantly higher in patients with HBR (OR 8.755, 95% CI 5.864-13.074; P < .01). The ARC-HBR criteria may predict in-hospital bleeding events and adverse outcomes in STEMI patients undergoing pPCI.

Relationship between in-hospital mortality and creatinine/albumin in patients with ST-elevation myocardial infarction without standard modifiable risk factors.

Background: Diabetes, hypertension, hyperlipidemia and smoking are associated with coronary artery disease and ST-elevation myocardial infarction (STEMI). However, patients without any classic risk factors have a higher mortality rate in the post-STEMI period. The aim of this study was to investigate the relationship between in-hospital mortality and creatinine/albumin ratio in patients with STEMI without modifiable risk factors. Materials & methods: All patients included in this study with a diagnosis of STEMI and who underwent primary percutaneous intervention between 2016 and 2020 were retrospectively analyzed. Patients were included in the standard modifiable cardiovascular risk factor (SMuRF) group if at least diabetes, hypertension, smoking or hyperlipidemia was present according to risk factors. Patients without these risk factors were considered the non-SMuRF group. Results: Creatinine/albumin ratio was found to be higher in non-SMuRF patients with mortality (p < 0.001). In multivariate logistic regression analysis, ejection fraction, hemoglobin and SMuRF were found to be inversely associated with in-hospital mortality (odds ratio [OR]: 0.48, 95% CI: 0.35-0.66, p < 0.001; OR: 0.70, 95% CI: 0.56-0.88, p = 0.002; OR: 0.57, 95% CI: 0.34-0.95, p = 0.03, respectively). Conclusion: The creatinine/albumin ratio can be used as a predictor of mortality in these patients; it can help identify high-risk patients beforehand.

Should coronary catheter laboratories be used in the treatment of ischemic stroke? Endovascular treatment in acute ischemic stroke performed by interventional cardiologists.

OBJECTIVE: The aim of this study was to investigate the technical success and in-hospital outcomes of endovascular thrombectomy (ET) in acute ischemic stroke (AIS) patients performed by interventional cardiologists. PATIENTS AND METHODS: ET for AIS provides fast, effective and safe recanalization. Insufficient number of catheter laboratories for stroke interventions and experienced interventional neurologists are limiting the widespread application of such a promising treatment method. RESULTS: 123 patients with AIS and eligible for ET were evaluated retrospectively. 65 patients were female (52.8%) and the mean age of the patients was 71.5 ± 11.9 years. Most of the patients had a middle cerebral artery (MCA) occlusion (112 patients, 91%). Successful recanalization (thrombolysis in cerebral infarction grading 2b or higher) was achieved in 109 patients (88.6%). Access site complication was observed only in 3 patients (2.4%). Intracranial bleeding was observed in 17 patients (13.8%) and only 8 of them were symptomatic (6.5%). In-hospital death occurred in 19 patients (15.4%). The initial National Institutes of Health Stroke Scale (NIHSS) was 16.8±3.3 (median 18) which improved significantly to 10.4±7.2 (median 11) at 24 hours (p<0.001). Dramatic neurologic improvement was observed in 60 of 123 patients (48.8%). The modified rankin score of the patients was significantly lower at discharge compared to admission (4.2±0.7 vs. 2.9±2, p<0.001). CONCLUSIONS: ET in AIS can be performed safely with high success rates by trained interventional cardiologists within the stroke team. Until the number of stroke centers is sufficient, endovascular treatment of AIS can be supported by experienced interventional cardiologists.

Prognostic value of triglyceride/glucose index in patients with ST-segment elevation myocardial infarction.

Aim: New parameters are emerging to predict prognosis in patients with ST-segment elevation myocardial infarction (STEMI). In this study we aimed to determine and compare the prognostic values of some metabolic indices in terms of predicting long-term mortality in patients with STEMI. Method: A total of 1900 nondiabetic patients who presented with STEMI and underwent percutaneous coronary intervention were included in the study. Multivariable Cox proportional regression analysis was used to determine and compare the predictive performance of triglyceride-glucose (TyG) index, triglyceride-high-density lipoprotein ratio (Ty/HDL) and admission glucose. Results: In multivariable Cox regression analysis, the model based on TyG index had better predictive performance than the Ty/HDL and admission blood glucose. Conclusion: The TyG index is more informative than Ty/HDL and admission glucose level to predict long-term all-cause mortality.

Comparison of two-year treatment outcomes between subthreshold micropulse (577 nm) laser and aflibercept for diabetic macular edema.

PURPOSE: To compare two-year treatment outcomes of subthreshold micropulse (577 nm) laser and aflibercept for diabetic macular edema (DME). STUDY DESIGN: Retrospective case-control study. METHODS: A total 164 eyes in 164 DME patients treated with either micropulse laser (86 eyes) or intravitreal aflibercept monotherapy (78 eyes) were recruited. Main outcome measures included at least five Early Treatment Diabetic Retinopathy Study (ETDRS) letters' improvement from baseline at 6, 12 and 24 months. RESULTS: Rescue aflibercept was initiated in 24% of eyes in micropulse laser group. At 6-month visit the aflibercept group achieved a higher percentage of eyes with at least 5-letter visual acuity improvement than micropulse laser group (56% vs 38%, P = 0.044), however, this was not the case at 12-month (45% vs 49%, P = 0.584) and 24-month visits (49% vs 57%, P = 0.227). At 6-month visit the aflibercept group achieved a higher percentage of eyes with at least 10% improvement of central macular thickness (73% vs 49%, P = 0.005), but this was not the case at 12-month (73% vs 70%, P = 0.995) and 24-month visits (85% vs 84%, P = 0.872). CONCLUSION: Aflibercept achieved faster and higher rates of anatomical and functional improvement than micropulse laser in DME patients. Long term efficacy of treatment did not result in significant differences between aflibercept monotherapy and micropulse laser in DME patients. Primary treatment of micropulse laser with deferred rescue aflibercept might be the treatment option without reducing the chance of visual improvement in DME eyes.

The association of acute--to--chronic glycemic ratio with no-reflow in patients with ST--segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

BACKGROUND: No­reflow (NR) is a strong and independent predictor of poor cardiovascular outcomes among patients with ST­segment elevation myocardial infarction (STEMI). AIMS: The aim of the study was to investigate the association of the acute­to­chronic (A/C) glycemic ratio with no­reflow (NR) in STEMI patients following primary percutaneous coronary intervention (PCI). METHODS: This retrospective study included 905 patients with STEMI. The A/C glycemic ratio was determined as admission blood glucose (ABG) divided by the estimated average glucose (eAG). We evaluated 2 primary models (full model and reduced model). The primary outcome was the presence of NR. RESULTS: The incidence of NR was 22.7% (206 cases) in the present study. We divided the study population into 3 tertiles (T1, T2, and T3) based on the ABG/eAG ratio. There was a stepwise increase of the frequency of NR from the T1 to T3 group (36 patients [12%] vs 70 patients [23%] vs 100 patients [33%]; respectively [P <0.001, for each group comparison]). In a full model, the ABG/eAG ratio (OR, 2.274; 95% CI, 1.587-3.26; P <0.001) was associated with NR. After the performance of a step-down backward variable selection method, the thrombus grade, the ABG/eAG ratio, the infarct­related artery diameter, and age remained in the reduced model. The ABG/eAG ratio (contributing 25.3% of the explainable outcome in the model) was one of the strong predictors of NR in the reduced model. CONCLUSIONS: To our knowledge, this might be the first study showing a significant relationship between the ABG/eAG ratios with NR in patients with STEMI after primary PCI.

Taming the late Quaternary phylogeography of the Eurasiatic wild ass through ancient and modern DNA.

Taxonomic over-splitting of extinct or endangered taxa, due to an incomplete knowledge of both skeletal morphological variability and the geographical ranges of past populations, continues to confuse the link between isolated extant populations and their ancestors. This is particularly problematic with the genus Equus. To more reliably determine the evolution and phylogeographic history of the endangered Asiatic wild ass, we studied the genetic diversity and inter-relationships of both extinct and extant populations over the last 100,000 years, including samples throughout its previous range from Western Europe to Southwest and East Asia. Using 229 bp of the mitochondrial hypervariable region, an approach which allowed the inclusion of information from extremely poorly preserved ancient samples, we classify all non-African wild asses into eleven clades that show a clear phylogeographic structure revealing their phylogenetic history. This study places the extinct European wild ass, E. hydruntinus, the phylogeny of which has been debated since the end of the 19th century, into its phylogenetic context within the Asiatic wild asses and reveals recent mitochondrial introgression between populations currently regarded as separate species. The phylogeographic organization of clades resulting from these efforts can be used not only to improve future taxonomic determination of a poorly characterized group of equids, but also to identify historic ranges, interbreeding events between various populations, and the impact of ancient climatic changes. In addition, appropriately placing extant relict populations into a broader phylogeographic and genetic context can better inform ongoing conservation strategies for this highly-endangered species.

[Application of means of surfaces with nonhomogeneity in estimating the incidence of pneumoconiosis].

Objective: To investigate the value of means of surfaces with nonhomogeneity (MSN) in esti-mating the incidence of pneumoconiosis. Methods: Based on the principal component analysis, all counties (districts) of Hebei Province, China, were divided into three categories according to the degree of pneumoconiosis hazards and the MSN model was used to estimate the incidence rate of pneumoconiosis and the number of pneu-moconiosis cases using the data of the incidence of pneumoconiosis in 2010. Results: With reference to the appli-cation requirements of the MSN model, results of the principal component analysis, and expert experience, the 172 counties (districts) in Hebei Province were divided into three categories with mild, moderate, and severe pneumoconiosis hazards. There were 74, 61, and 49 counties in the above categories, respectively, and 12, 12, and 25 counties were selected from them, respectively. The estimated number of pneumoconiosis cases in Hebei Province was 2105, and the incidence rate was 261.5 per hundred thousand, with a standard error of esti-mation of 389.9 per hundred thousand. Conclusion: The MSN model provides a new thought and method for es-timating the number of pneumoconiosis cases.

Two-dimensional speckle-tracking echocardiography-based left atrial strain parameters predict masked hypertension in patients with hypertensive response to exercise.

OBJECTIVE: We aim to study left atrial (LA) strains in patients with hypertensive response to exercise (HRE) and determine their usefulness in predicting masked hypertension (HT). METHODS: Ninety-eight normotensive patients who had HRE were included and were divided into two groups after masked HT had been diagnosed by ambulatory blood pressure monitoring. Conventional echocardiographic parameters and two-dimensional speckle-tracking echocardiography-based LA strain parameters were compared. RESULTS: Patients with masked HT have higher left ventricle mass index (LVMI) (88.1±11.3 vs. 82.5±8.7 g/m, P<0.05), left atrium maximum volume index (LAVI) (34.5±5.1 vs. 30.2±5.6 ml/m, P<0.001), lower global longitudinal LA strain during ventricular systole (GLAs-res) (32.5±8.9 vs. 40.2±9.1%, P<0.001), and lower global longitudinal LA strain during late diastole (GLAs-pump) (15.8±4.1 vs. 18.1±5.8%, P<0.05). In univariate analysis, a good negative correlation was found between GLAs-res versus LAVI (r=-0.451, P<0.001), GLAs-res versus LVMI (r=-0.457, P<0.001) and a moderate negative correlation was present between GLAs-pump versus LAVI (r=-0.317, P<0.001) and GLAs-pump versus LVMI (r=-0.288, P<0.05). GLAs-res and LAVI were found to be independent predictors of masked HT. Receiver-operating characteristic analysis was carried out. Area under the curve to predict masked HT was 0.729 (95% confidence interval: 0.623-0.832, P<0.001). GLAs-res less than 33.1% predicted masked HT with 73% sensitivity and 61.5% specificity. CONCLUSION: LA strain parameters were impaired in patients with masked HT and can be used to predict the presence of masked HT in patients with HRE.

Preliminary results of CO2 laser-assisted sclerectomy surgery (CLASS) in the treatment of advanced glaucoma in a Chinese population.

To evaluate the efficacy and safety of CO2 laser-assisted sclerectomy surgery (CLASS) in Chinese patients with advanced glaucoma.Patients with advanced glaucoma who were candidates for glaucoma filtration surgery were included. The intraocular pressure (IOP) and number of antiglaucoma medications were documented before surgery and at all postoperative clinic visits. All intra- and postoperative complications were documented. The primary outcome measures were the changes in IOP and medication use before and after the procedure as well as complications from the procedure. The secondary outcome measure included the CLASS success rate.Twenty patients (23 eyes) underwent CLASS between November 2014 and September 2015. Nineteen eyes had primary open-angle glaucoma, 2 eyes had primary angle-closure glaucoma, and 2 eyes had uveitic glaucoma. One patient was lost to follow-up. The mean age of subjects was 68.1 ±â€Š11.9 years. IOP was significantly reduced at 1 day and 1 week after CLASS. At 6 months, the IOP and number of medications were significantly reduced by 19.0% and 38.2%, respectively (both P < 0.0001). One patient had intraoperative trabeculo-Descemet membrane perforation. Two patients required laser goniopuncture and 2 required needling between 3 and 6 months postoperatively. The overall success rate was 81.8% at 6 months.CLASS achieved a modest IOP reduction in the early postoperative period and was overall a safe procedure for advanced glaucoma.

HEMATOLOGICAL MARKERS OF THE NO-REFLOW PHENOMEN ON IN-PATIENTS UNDERGOING PRIMARY PERCUTANEOUS CORONARY INTERVENTION.

The study aims to investigate hematological parameters of the no-reflow phenomenon (NRP) developed in patients underwent primary percutaneous coronary intervention (pPCI) due to diagnosis of ST elevation myocardial infarction (STEMI). The study sample consisted of a total of 90 patients, of which 44 patients who underwent pPCI and developed NRP without anemia and chronic renal failure (mean age was 64; 34 males and 10 females) were included in the experimental group, and the control group consisted of 46 patients with normal reperfusion flow (mean age was 58; 34 males and 12 females). In both groups, Red blood-cell Distribution Width (RDW), Mean Platelet Volume (MPV), plateletcrit (PCT), Platelet Distribution Width (PDW), and neutrophil count were observed. The demographic characteristics of both groups were similar, except the higher mean age of the experimental group (age; 64.0±12.6; 58.0±12.5). No correlation was found between development of no-reflow and incidence of risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking, family history and gender. In the no-reflow group, RDW level (16.2%±2.1; 14.2%±0.7, p<0.001), MPV level (7.9±1.2; 7.3±0.8, p<0.05), PDW level (18.1±1.2; 17.4±1.2, p<0.05), PCT level (0.2±0.06 vs 0.17±0.05) and neutrophil count (9.9±3.7; 7.1±3.3, p<0.001) was found to be higher than the control group. According to logistic regression analysis, RDW (OR; 23.4, <95% Cl 4.6-118.9, p<0.001), PDW (OR; 2.8, <95% Cl 1.2-6.4, p<0.05) and neutrophil count (OR; 1.4, Cl 1.1-1.9, p<0.05) were found to be the predictors of NRP development. Hemogram is a cheap and easy to apply test. In our study, a relationship between the NRP development and RDW, PDW, MPV, PCT, and neutrophil counts was found in patients who underwent pPCI. At the same time, RDW, PDW, and the neutrophil count were found to be predictors of no-reflow development.

Incidence and Risk Factors of Retinopathy of Prematurity From 2 Neonatal Intensive Care Units in a Hong Kong Chinese Population.

PURPOSE: To determine the incidence and risk factors of retinopathy of prematurity (ROP) in very low birth weight (VLBW) preterm Chinese infants. DESIGN: Retrospective review. METHODS: Medical records were reviewed for all neonates screened for ROP between January 2007 and December 2012 in Hong Kong. Screening was offered to VLBW (≤1500 g) and/or preterm (gestation, ≤32 weeks) neonates using the Royal College of Ophthalmologists ROP guideline and the International Classification of ROP by 3 pediatric ophthalmologists. Maternal and neonatal covariates were analyzed using univariate and multivariable logistic regression analyses for both ROP and type 1 ROP. RESULTS: Of the 513 screened infants, the mean gestational age (GA) was 30.0 ± 2.5 weeks and the mean birth weight (BW) was 1232.6 ± 325.2 g. The incidence of ROP and type 1 ROP was 18.5% and 3.7%, respectively. In univariate analysis, a lighter BW, lower GA, blood transfusion, patent ductus arteriosus, nonsteroidal anti-inflammatory drug use, postnatal hypotension, inotropes usage, low Apgar scores, sepsis, mechanical ventilation, supplementary oxygen use, respiratory distress syndrome, anemia, surfactant use, and bronchopulmonary dysplasia were found to be associated with the development of both ROP and type 1 ROP (P < 0.05). In multivariable logistic regression analysis, BW, GA, and intraventricular hemorrhage were significant risk factors for ROP. Preeclampsia and eclampsia were the only protective factors for ROP development on multivariable logistic regression analysis (P = 0.02). CONCLUSIONS: In VLBW preterm Chinese infants, lower GA, lighter BW, and intraventricular hemorrhage were significant risk factors for ROP, whereas preeclampsia and eclampsia were protective.

Efficacy and Safety of Trabectome Surgery in Chinese Open-Angle Glaucoma.

To investigate the clinical outcome of the Trabectome in Chinese open-angle glaucoma (OAG). This prospective case series recruited pseudophakic glaucoma subjects with open-angle configuration. Trabeculectomy ab interno was performed using the Trabectome to 120° of the trabecular meshwork. Intraocular pressure (IOP) and medications were recorded preoperatively and every 3 months postoperatively. Visual acuity was measured preoperatively and at 1 and 6 months postoperatively. One-way ANOVA with Tukey Multiple Comparison Test were used to measure the pre and postoperative parameters. In 19 eyes of 19 Chinese subjects, 26.3% were uveitic, 68.4% were primary open-angle glaucoma, and 5.3% had a history of chronic angle-closure glaucoma with open-angles after cataract extraction. The subjects' mean age was 67.5 ±â€Š14.4 years, with 4 females and 15 males. Two patients required secondary filtration procedure. At 6 months, the IOP reduced by 34.8% (24.4 ±â€Š4.4 mm Hg to 15.9 ±â€Š5.1 mm Hg, P < 0.0001). The number of types of antiglaucoma medications was reduced by 28.2% (3.9 ±â€Š0.8-2.8 ±â€Š1.6, P < 0.0001). The visual acuity was static at 1 and 6 months postoperatively (P = 0.4). There were no intraoperative complications. 26.3% of subjects had a transient IOP spike > 21 mm Hg, 1 had hyphema requiring washout, and 1 had reactivation of herpetic keratitis. The success rate at 6 months was 89.5%. Trabectome achieved a modest reduction in IOP and medications in the majority of pseudophakic Chinese OAG eyes.

The Relationship Between High-Sensitivity C-Reactive Protein Levels and Left Ventricular Hypertrophy in Patients With Newly Diagnosed Hypertension.

The authors aimed to evaluate the relationship between high-sensitivity C-reactive protein (hs-CRP) and presence of left ventricular hypertrophy and diastolic dysfunction in patients with hypertension. A total of 95 newly diagnosed hypertensive patients (mean age, 54±10 years) and 20 controls were included in this study. Patients were divided into four groups according to relative wall thickness as normal, concentric remodeling, concentric, and eccentric hypertrophy. hs-CRP was measured in all patients and serum hs-CRP level was shown to be increased in patients with hypertension compared with controls (0.57 mg/dL vs 0.25 mg/dL, respectively; P<.001). The hs-CRP level was highest in patients with concentric hypertrophy. When compared with controls, serum hs-CRP level was significantly higher in patients with concentric remodeling (0.61±0.3 mg/dL vs 0.43±0.5 mg/dL, P<.030) and concentric hypertrophy (0.69±0.3 mg/dL vs 0.43±0.5 mg/dL, P<.032). The present study shows that serum hs-CRP is significantly associated with left ventricular diastolic function and concentric hypertrophy in patients with hypertension.

MicroPulse Laser Trabeculoplasty for the Treatment of Open-Angle Glaucoma.

The aim of the study was to investigate the safety and efficacy of using MLT in the treatment of open-angle glaucoma (OAG).This prospective cohort included subjects ≥18 years of age with OAG, defined as the open angle on gonioscopy with glaucomatous optic neuropathy evident from optical coherence tomography. Subjects with IOP < 21 mm Hg were classified as normal tension glaucoma and those with IOP ≥21 mm Hg were classified as primary open-angle glaucoma. Those with angle closure, secondary glaucoma, prior laser trabeculoplasty, use of systemic IOP-lowering medications, corneal pathologies, follow-up <6 months, recent intraocular surgery, or only 1 functional eye were excluded. A single session of unilateral MLT treatment was delivered using a 577 nm diode laser to 360° of the trabecular meshwork to reduce IOP or medication load. Medications were titrated up or down at 1 month after laser to achieve a 25% IOP reduction from presentation or an IOP <18 mm Hg, whichever was lower. The following were compared using the Repeated Measures ANOVA with Bonferroni's Multiple Comparison Test: IOP (on presentation, pre-MLT, day 1, 1 week, 1 month, 3 months, and 6 months after MLT) and the number of medications (pre-MLT, 3 months, and 6 months after MLT). After 6 months, responders with initial success to MLT (IOP reduction ≥20% at 1 month) received treatment in the fellow eye.In 48 subjects with OAG, the mean number of MLT shots applied was 120.5 ±â€Š2.0 shots using a mean energy of 1000 mW per shot. Only 7.5% had a mild, self-limiting anterior uveitis postlaser with no change in the Snellen visual acuity at 6 months (P's > 0.5). The IOP and number of medications were significantly reduced at all time intervals following MLT compared to the pre-MLT level (P's < 0.0001). At 6 months, the IOP was reduced by 19.5% in addition to a 21.4% reduction in medication compared to pretreatment levels. The MLT success rate was 72.9%. During the first 6 months only 2.1% required a repeated laser trabeculoplasty.MLT was effective in reducing IOP and medications in OAG with minimal postlaser inflammation and low failure rate at 6 months following laser.
