RESUMEN

PURPOSE: To analyze the rate and time of occurrence of intraocular pressure (IOP) elevation early after trabectome surgery (TOM) and the characteristics of glaucoma patients recovering from IOP elevation. METHOD: Four hundred sixty eyes of 460 glaucoma (191 primary and 269 secondary open-angle glaucoma) patients who underwent TOM were evaluated. IOP elevation early after TOM was diagnosed when IOP increased by more than 5 mmHg over baseline within 1 week to 3 months. If the IOP decreased with the administration of anti-glaucoma eye drops alone, patients were classified as recovered. If the IOP did not decrease despite additional anti-glaucoma eye drop use, patients were classified as non-recovered. The rate and time of occurrence of IOP elevation early after TOM were investigated. Demographic and ocular variables related to recovery and non-recovery were identified by multivariate logistic regression analysis. RESULTS: Of the 460 patients, IOP elevation early after TOM occurred in 102 (22.2%). IOP elevation occurred most frequently at postoperative week 1. Of the 102 patients with IOP elevation, 55 (53.9%) recovered and 47 (46.1%) did not. A large hyphema size the day after surgery was associated with increased likelihood of recovery from IOP elevation (odds ratio [OR], 6.6). A history of past selective laser trabeculoplasty (SLT; OR, 0.10) and high baseline IOP (OR, 0.86) were associated with reduced likelihood of recovery from IOP elevation. CONCLUSION: IOP elevation early after TOM occurred most frequently at postoperative week 1. Patients with a large hyphema size, no history of SLT, and a lower baseline IOP recovered from IOP elevation early after TOM. A large hyphema the day after surgery suggested an increased likelihood of recovery from IOP elevation.

RESUMEN

PURPOSE: To evaluate the 72-month clinical results of trabectome surgery (TOM) in patients with primary open-angle glaucoma (POAG), secondary OAG and childhood glaucoma. METHOD: A total of 305 eyes from 249 glaucoma patients were analyzed in the current retrospective single-center study. Kaplan-Meier analysis was performed using three criteria: criterion A (postoperative intraocular pressure [IOP] ≤ 21 mmHg and ≥ 20% reduction from baseline IOP); criterion B (postoperative IOP ≤ 18 mmHg and ≥ 20% reduction from baseline IOP); and criterion C (postoperative IOP ≤ 16 mmHg and ≥ 20% reduction from baseline IOP). The changes in IOP, medication score, success probability, results of the multivariate analysis for success and failure risk factors, and complications were analyzed. RESULTS: The baseline IOP in all glaucoma patients decreased from 29.2 ± 9.8 mmHg with a 5.3 ± 1.7 medication score to 16.4 ± 5.8 mmHg (- 43.8%) with a 4.2 ± 1.5 medication score at 72 months (p < 0.01). The success probabilities in all cases for 72 months based on criterion A, B, and C were 44%, 35%, and 17%, respectively. For criterion A, no significant differences were found in the success probability according to the glaucoma subtype for 72 months. The combined surgical procedure significantly decreased the failure risk (hazard ratio [HR]: 0.59). On the other hand, the presence of POAG (HR: 1.6) and a history of past selective laser trabeculoplasty (HR: 2.2) significantly increased failure risk. One patient (0.3%) demonstrated endophthalmitis after TOM but recovered through appropriate treatment. CONCLUSION: At the 72-month time point, approximately half of the glaucoma patients maintained an IOP ≤ 21 mmHg with ≥ 20% IOP reduction. TOM is a safe surgery but may not yield sufficient IOP reduction in patients who have received SLT or have POAG.

RESUMEN

We performed a systematic review and meta-analysis to re-evaluate the effectiveness of angiotensin-converting enzyme inhibitors (ACE-I) in the reduction of pneumonia risk. We searched relevant publications in five databases. All studies included patients older than 18 years, who had used ACE-I as an intervention, and had assessed pneumonia. Seven RCTs (n = 8704) and 38 observational studies (n = 1,705,030) were included. The overall risk of bias was high. ACE-I-treated patients were associated with a slightly lower risk of pneumonia, both from pooled estimates of RCTs [pooled odds ratio (OR), 0.75; 95% confidence interval (CI), 0.62-0.90; low certainty of evidence] and observational studies (pooled OR, 0.85; 95% CI, 0.78-0.92; very low certainty of evidence). Considering the small effect size of ACE-I in preventing pneumonia and the low quality of the evidence, routine use of ACE-I for pneumonia prevention is not recommended.

RESUMEN

To explore induced islet neogenesis in the liver as a strategy for the treatment of diabetes, we used helper-dependent adenovirus (HDAD) to deliver the pancreatic duodenal homeobox-1 gene (Ipf1; also known as Pdx-1) to streptozotocin (STZ)-treated diabetic mice. HDAD is relatively nontoxic as it is devoid of genes encoding viral protein. Mice treated with HDAD-Ipf1 developed fulminant hepatitis, however, because of the exocrine-differentiating activity of Ipf1. The diabetes of STZ mice was partially reversed by HDAD-mediated transfer of NeuroD (Neurod), a factor downstream of Ipf1, and completely reversed by a combination of Neurod and betacellulin (Btc), without producing hepatitis. Treated mice were healthy and normoglycemic for the duration of the experiment (>120 d). We detected in the liver insulin and other islet-specific transcripts, including proinsulin-processing enzymes, beta-cell-specific glucokinase and sulfonylurea receptor. Immunocytochemistry detected the presence of insulin, glucagon, pancreatic polypeptide and somatostatin-producing cells organized into islet clusters; immuno-electron microscopy showed typical insulin-containing granules. Our data suggest that Neurod-Btc gene therapy is a promising regimen to induce islet neogenesis for the treatment of insulin-dependent diabetes.

RESUMEN

BACKGROUND: Interstitial cells of Cajal (ICCs), which express c-Kit receptor tyrosine kinase (KIT), play an important role in gastrointestinal motility. Loss of ICCs likely contributes to diabetic gastrointestinal motility disorder, however, the mechanism of attrition remains unknown. Here, we test the hypothesis that the bone marrow-derived progenitors are an important source of intestinal ICCs and that decreased homing of these progenitors in diabetes contributes to ICC diminution. METHODS: Wild type mice were X-ray irradiated, transplanted with bone marrow (BMT) from green fluorescence protein (GFP)-transgenic (TG)-mice and subsequently made diabetic by streptozotocin (STZ) injection. Intestinal homing of GFP-positive bone marrow-derived cells was examined 2 or 5 months after STZ treatment. RESULTS: In the BMT-mice, we found many GFP-positive bone marrow-derived cells (BMDCs) in most parts of the intestinal area, the number of BMDCs was significantly decreased in diabetic mice compared with nondiabetic controls. As a representative area, we further examined the myenteric plexus of the proximal small intestine, and found that the cell numbers of ICCs marked by c-Kit-positive immunoreactivity were decreased by more than 40% in diabetic versus nondiabetic mice. Furthermore, numbers of c-Kit+/GFP+ and c-Kit+/GFP- cells were similar in nondiabetic mice, and decreased by 45.8% and 42.0%, respectively, in diabetic mice. CONCLUSION: These results suggest that the decreased homing from the bone marrow is a major cause of ICC loss in the intestine in diabetes mellitus.

RESUMEN

To investigate if intracellular glycerol content plays a role in the regulation of insulin secretion in pancreatic beta cells, we studied the expression of the glycerol channels, or aquaglyceroporins, encoded by the aquaporin 3 (Aqp3), Aqp7, and Aqp9 genes in mouse islets. We found expression of Aqp7 only, not that of Aqp3 or Aqp9, in the endocrine pancreas at both the mRNA (by reverse transcription-PCR) and protein (by immunohistochemistry) levels. Immunohistochemistry revealed a complete overlap between insulin and Aqp7 immunostaining in the pancreatic islet. Inactivation of Aqp7 by gene targeting produced viable and healthy mice. Aqp7-/- mice harbored an increased intraislet glycerol concentration with a concomitant increase of the glycerol kinase transcript level and enzyme activity. The islet triglyceride content in the Aqp7-/- mice was also increased compared to that in the Aqp7+/+ mice. Interestingly, Aqp7-/- mice displayed reduced beta-cell mass and insulin content but increased insulin-1 and insulin-2 mRNAs. The reduction of beta-cell mass in Aqp7-/- mice can be explained at least in part by a reduction in cell proliferation through protein kinase C and the c-myc cascade, with a reduction in the transcript levels of these two genes. Concomitantly, there was a decreased rate of apoptosis, as reflected by terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling and caspase 3 and Bax expression in Aqp7-/- mice. Compared with Aqp7+/+ islets, islets isolated from Aqp7-/- mice secreted insulin at a higher rate under basal low-glucose conditions and on exposure to a high (450 mg/dl) glucose concentration. Aqp7-/- mice exhibited normal fasting blood glucose levels but elevated blood insulin levels. Their plasma glucose response to an intraperitoneal (i.p.) glucose tolerance test was normal, but their plasma insulin concentrations were higher than those of wild-type mice during the 2-h test. An i.p. insulin tolerance test showed similar plasma glucose lowering in Aqp7-/- and Aqp7+/+ mice, with no evidence of insulin resistance. In conclusion, we found that pancreatic beta cells express AQP7, which appears to be a key regulator of intraislet glycerol content as well as insulin production and secretion.

RESUMEN

PURPOSE: The purpose of this study was to evaluate the influence of trabectome surgery on corneal endothelial cells by site. METHODS: Retrospective observational study. Trabectome surgeries were performed on 159 eyes of 132 adult Japanese patients. Corneal endothelial cells were measured at the center (C), inferior (I), nasal inferior (NI), nasal superior (NS), superior (S), temporal superior (TS), and temporal inferior (TI) sectors at <1 month preoperatively and 3, 6, 12, 24, and 36 months postoperatively, for changes in corneal endothelial cell density (ECD), coefficient of variation (CV), and incidence of hexagonal cells (6A). RESULTS: Mean preoperative ECD in all groups were 2401±451 (SD) cells/mm (C), 2366±450 cells/mm (I), 2397±479 cells/mm (NI), 2476±554 cells/mm (NS), 2493±596 cells/mm (S), 2464±558 cells/mm (TS), and 2329±510 cells/mm (TI). The 12-month postoperative mean ECDs were 2344±480 cells/mm (C), 2312±469 cells/mm (I), 2325±536 cells/mm (NI), 2473±517 cells/mm (NS), 2438±607 cells/mm (S), 2227±578 cells/mm (TS), and 2193±523 cells/mm (TI). There was no change in ECD in all sectors before and after surgery. ECD decreased at the TS and TI in combination with cataract surgery (2620±430 and 2445±384 cells/mm) preoperatively to 2264±501 and 2216±477 cells/mm at 12 months postoperatively. CV and 6A did not change at all sites in all surgical procedures before and after surgery. CONCLUSIONS: Trabectome surgery involves minimal effects to corneal endothelial cells, although long-term prospective studies with greater sample sizes are necessary to confirm this conclusion.

RESUMEN

The aim of this cross-sectional study was to evaluate the results of a visual field (VF) test for patients with glaucoma and pseudo-fixation loss. These patients exhibit fixation loss (FL) rates >20% with the Humphrey Field Analyzer (HFA); however, actual fixation stabilizes when a head-mounted perimeter (imo) is used. This device is able to adjust the stimulus presentation point by tracking eye movements. We subjected 54 eyes of 54 patients with glaucoma and pseudo-FL to the HFA 30-2 or 24-2 Swedish Interactive Threshold Algorithm -Standard protocol. All patients also underwent the imo 30-2 or 24-2 Ambient Interactive Zipper Estimated Sequential Testing protocol after HFA measurement. We compared HFA and imo reliability indices [including false-positive (FP) responses, false-negative (FN) responses, and FL rate], global indices [including mean deviation (MD), visual field index (VFI), and pattern standard deviation (PSD)], and retinal sensitivity for each test point. There were no significant differences in MD, VFI, and PSD between HFA and imo, and these measures were strongly correlated (r > 0.96, p < 0.01). There were no significant differences in FP and FN between both devices, while FL measured with HFA (27.5%) was significantly reduced when measured with imo (13.2%) (p < 0.01). There was no correlation in FL and FN between both devices, and a weak correlation for FP (r = 0.29, p = 0.04). At each test point, retinal sensitivity averaged 1.7 dB higher with HFA, compared with imo (p < 0.01). There was no significant variability in global indices in patients with pseudo-FL. The FP response rate might have influenced measures of FL in patients with glaucoma and pseudo-FL.

RESUMEN

PURPOSE: This prospective observational study compared the performance of size modulation standard automated perimetry with the Octopus 600 10-2 test program, with stimulus size modulation during testing, based on stimulus intensity and conventional standard automated perimetry, with that of the Humphrey 10-2 test program in glaucoma patients. METHODS: Eighty-seven eyes of 87 glaucoma patients underwent size modulation standard automated perimetry with Dynamic strategy and conventional standard automated perimetry using the SITA standard strategy. The main outcome measures were global indices, point-wise threshold, visual defect size and depth, reliability indices, and test duration; these were compared between size modulation standard automated perimetry and conventional standard automated perimetry. RESULTS: Global indices and point-wise threshold values between size modulation standard automated perimetry and conventional standard automated perimetry were moderately to strongly correlated (p < 0.01). However, the correlation coefficient of point-wise threshold value for the central zone was significantly lower than that for the peripheral zone (χ2 > 33.40, p < 0.01). Better mean defect and point-wise threshold values were obtained with size modulation standard automated perimetry than with conventional standard automated perimetry, but the visual-field defect size was smaller (p < 0.01) and depth shallower (p < 0.01) on size modulation-standard automated perimetry than on conventional standard automated perimetry. The reliability indices, particularly the false-negative response, of size modulation standard automated perimetry were worse than those of conventional standard automated perimetry (p < 0.01). The test duration was 6.5% shorter with size modulation standard automated perimetry than with conventional standard automated perimetry (p = 0.02). CONCLUSIONS: Global indices and the point-wise threshold value of the two testing modalities correlated well. However, the potential of a large stimulus presented at an area with a decreased sensitivity with size modulation standard automated perimetry could underestimate the actual threshold in the 10-2 test protocol, as compared with conventional standard automated perimetry.

RESUMEN

This study aimed to compare the diagnostic capability of Pulsar perimetry (Pulsar) in pre-perimetric glaucoma (PPG) and early glaucoma (EG) with that of Flicker perimetry (Flicker) and spectral-domain optical conference tomography (SD-OCT). This prospective cross-sectional study included 25 eyes of 25 PPG patients, 35 eyes of 35 EG patients, and 42 eyes of 42 healthy participants. The diagnostic capability using the area under the curve (AUC) of the best parameter and agreement of detectability between structural and functional measurements were compared. For PPG patients, the AUC of Pulsar, Flicker, OCT-disc, and OCT-macular was 0.733, 0.663, 0.842, and 0.780, respectively. The AUC of Flicker was significantly lower than that of OCT-disc (p = 0.016). For EG patients, the AUC of Pulsar, Flicker, OCT-disc, and OCT-macular were 0.851, 0.869, 0.907, and 0.861, respectively. There was no significant difference in AUC among these methods. The agreement between structural and functional measurements expressed by kappa value ranged from -0.16 to 0.07 for PPG and from 0.01 to 0.25 for EG. Although the diagnostic capability of Pulsar in the PPG and EG groups was equal to that of Flicker and SD-OCT, the agreements between structural and functional measurements for both PPG and EG were poor.

RESUMEN

PURPOSE: We assess the diagnostic ability and repeatability of a new suprathreshold glaucoma screening test (GST) comprising 28 test points and a 1-of-3 sampling strategy at 95% of the normal limit for standard automated perimetry (SAP) in early to advanced glaucoma. METHODS: This prospective cross-sectional study included 96 eyes of patients with early, moderate, or advanced glaucoma and 37 eyes of normal controls. Participants were evaluated by the G-Dynamic threshold test once and the GST twice, in random order, using the Octopus 600 perimeter. The diagnostic ability of GST was assessed by comparison with the G-Dynamic threshold obtained by receiver operating characteristic analysis. Repeatability was assessed by κ statistics for agreement on glaucoma diagnosis and each test point. RESULTS: Although the G-Dynamic test exhibited significantly higher areas under the curve (AUC) than the GST1st (P = 0.009) in early glaucoma, there were no significant differences in any other AUCs between the two methods. The κ values for repeatability of glaucoma diagnosis and each test point were 0.747 to 1.0 and 0.537 to 1.0, respectively. The duration of the GST in the control and early glaucoma groups was less than a minute, while that in the moderate and advanced glaucoma groups was within 1.5 minutes. CONCLUSION: The diagnostic ability of the new suprathreshold GST for early to advanced glaucoma was high, with moderate to strong repeatability and short test duration. TRANSLATIONAL RELEVANCE: There currently are no prominent suprathreshold screening strategies using SAP. The GST would be an effective clinical method for glaucoma screening.

RESUMEN

Aim: Emergency department overcrowding is problematic. Some emergency departments have established a triage system to prevent overcrowding; however, effective management of a triage system requires knowledge of factors that influence emergency department attendance. Therefore, we investigated the effect of ambient temperature on emergency department attendance, as well as the types of patients that may have been affected. Methods: Data on emergency department attendance at Shiga University of Medical Science Hospital (Otsu, Japan) were retrospectively collected from 1 April, 2007 to 31 March, 2010. Attendance was classified into eight categories based on a combination of symptoms (trauma or non-trauma), transport (by ambulance or walk-in), and severity (serious or non-serious). Results: A total of 7,755 patients (4,120 [53.1%] men and 3,635 [46.9%] women) attended the emergency department during the study period. Statistically significant seasonal differences were observed in emergency department attendance in walk-in and non-serious groups of both trauma and non-trauma patients (P < 0.01), with the smallest differences occurring during winter. In a linear regression model, the mean ambient temperature had a positive correlation with emergency department attendance only in the walk-in and non-serious group of non-trauma patients during the summer (y = 0.092 × [mean ambient temperature] - 0.565). Conclusion: In the walk-in and non-serious group of non-trauma patients, emergency department attendance significantly increased with the increase in mean ambient temperature during summer. In emergency department triage systems, it may be more effective to evaluate non-trauma and walk-in patients during summer, especially on hot days.

RESUMEN

This prospective randomized study compared test results of size modulation standard automated perimetry (SM-SAP) performed with the Octopus 600 and conventional SAP (C-SAP) performed with the Humphrey Field Analyzer (HFA) in glaucoma patients. Eighty-eight eyes of 88 glaucoma patients underwent SM-SAP and C-SAP tests with the Octopus 600 24-2 Dynamic and HFA 24-2 SITA-Standard, respectively. Fovea threshold, mean defect, and square loss variance of SM-SAP were significantly correlated with the corresponding C-SAP indices (P < 0.001). The false-positive rate was slightly lower, and false-negative rate slightly higher, with SM-SAP than C-SAP (P = 0.002). Point-wise threshold values obtained with SM-SAP were moderately to strongly correlated with those obtained with C-SAP (P < 0.001). The correlation coefficients of the central zone were significantly lower than those of the middle to peripheral zone (P = 0.031). The size and depth of the visual field (VF) defect were smaller (P = 0.039) and greater (P = 0.043), respectively, on SM-SAP than on C-SAP. Although small differences were observed in VF sensitivity in the central zone, the defect size and depth and the reliability indices between SM-SAP and C-SAP, global indices of the two testing modalities were well correlated.

RESUMEN

AIM: To compare the corneal biomechanical properties difference by ocular response analyzer (ORA) in normal tension glaucoma (NTG) patients with different visual field (VF) progression speed. METHODS: NTG patients with well-controlled Goldmann applanation tonometer (GAT) who routinely consulted Kitasato University Hospital Glaucoma Department between January 2010 and February 2014 were enrolled. GAT and ORA parameters including corneal compensated intraocular pressure (IOPcc), Goldmann estimated intraocular pressure (IOPg), corneal hysteresis (CH), corneal resistance factor (CRF) were recorded. VF was tested by Swedish interactive threshold algorithm (SITA)-standard 30-2 fields. All patients underwent VF measurement regularly and GAT did not exceed 15 mm Hg at any time during the 3y follow up. Patients were divided into four groups according to VF change over 3y, and ORA findings were compared between the upper 25(th) percentile group (slow progression group) and the lower 25(th) percentile group (rapid progression group). RESULTS: Eighty-two eyes of 56 patients were studied. There were 21 eyes (21 patients) each in rapid and slow progression groups respectively. GAT, IOPcc, IOPg, CH, CRF were 12.1±1.4 mm Hg, 15.8±1.8 mm Hg, 12.8±2.0 mm Hg, 8.4±1.1 mm Hg, 7.9±1.3 mm Hg respectively in rapid progression group and 11.5±1.3 mm Hg, 13.5±2.1 mm Hg, 11.2±1.6 mm Hg, 9.3±1.1 mm Hg, 8.2±0.9 mm Hg respectively in slow progression group (P=0.214, <0.001, 0.007, 0.017, 0.413, respectively). In bivariate correlation analysis, IOPcc, IOPcc-GAT and CH were significant correlated with mΔMD (r=-0.292, -0.312, 0.228 respectively, P=0.008, 0.004, 0.039 respectively). CONCLUSION: Relatively rapid VF progression occurred in NTG patients whose IOPcc are rather high, CH are rather low and the difference between IOPcc and GAT are relatively large. Higher IOPcc and lower CH are associated with VF progression in NTG patients. This study suggests that GAT measures might underestimate the IOP in such patients.

RESUMEN

PURPOSE: To evaluate the short-term results of Trabectome surgery performed on Japanese patients. METHODS: Retrospective observational study. Trabectome surgery was performed on 117 eyes from 101 patients at Kitasato University Hospital from December 2010 to June 2013, involving 48 eyes with primary open-angle glaucoma (POAG), 62 eyes with secondary open-angle glaucoma (SOAG), and 7 eyes with developmental glaucoma. Trabectome surgery alone was performed on 34 phakic eyes (the phakic group) and 35 pseudophakic eyes (the pseudophakic group), and Trabectome surgery combined with phacoemulsification (the combined surgery group) was performed on 48 eyes. The main outcomes assessed were intraocular pressure (IOP), number of IOP-lowering medications, and success probabilities using Kaplan-Meier life-table analyses. Failure risk factors were identified using the Cox proportional hazards ratio. RESULTS: In all cases, after a mean follow-up of 18.5 ± 13.5 months, IOP was reduced from 31.6 ± 9.9 (SD) mmHg using 5.0 ± 1.7 medications to 16.4 ± 5.4 mmHg using 3.8 ± 1.8 medications. One year after surgery, IOP was reduced from 29.4 ± 7.8 to 16.1 ± 3.8 mmHg in POAG, from 33.6 ± 11.1 to 14.7 ± 2.9 mmHg in SOAG, from 33.0 ± 10.2 to 15.7 ± 3.3 mmHg in the phakic group, from 32.6 ± 9.3 to 15.3 ± 3.0 mmHg in the pseudophakic group, and from 29.9 ± 10.0 to 15.2 ± 3.0 mmHg in the combined surgery group. There were no statistically significant differences in IOP at each measurement point, either between POAG and SOAG or among the three procedure subtypes. The POAG and SOAG success rates at 12 months using postoperative IOP ≤ 21 mmHg and ≥20 % reduction in baseline as criteria were 53.9 and 77.2 %, respectively (p = 0.024, log-rank test). Twenty-one eyes (17.9 %) needed additional trabeculectomy. None of the univariate and multivariate risk factors for failure were detected. CONCLUSIONS: Trabectome surgery is safe and effective for Japanese patients whose target IOP is 18 mmHg or above. However, it is necessary to carefully consider Trabectome surgery for advanced POAG cases.

RESUMEN

This study sought to describe a glaucoma patient with interface fluid syndrome (IFS) induced by uncontrolled intraocular pressure (IOP) without triggering factors after laser in situ keratomileusis (LASIK). Case report and review of the literature. A 23-year-old man with open-angle glaucoma underwent bilateral LASIK for myopia in 2009. Two years later, the patient reported sudden vision loss. The IOP in the right eye was not measurable using Goldmann applanation tonometry (GAT), but was determined to be 33.7 mm Hg using a noncontact tonometer. IFS was diagnosed based on the presence of space-occupying interface fluid on anterior segment optical coherence tomography images. After a trabeculectomy was performed, the IOP decreased to 10 mm Hg, and GAT measurement became possible. However, the corneal fold remained visible in the flap interface. Six months later, the IOP in the left eye increased, and a trabeculectomy was performed during the early stages of this increase in IOP. Following this procedure, the IOP decreased, and visual acuity remained stable. In glaucoma cases that involve a prior increase in IOP, IOP can continue to increase during the disease course even if temporary control of IOP has been achieved. If LASIK is performed in such cases, the treatment of glaucoma becomes insufficient because of underestimation of the typical IOP. In fact, the measurement of IOP can become difficult because of high-IOP levels. Therefore, LASIK should not be performed on patients with glaucoma who are at high risk of elevated IOP.

RESUMEN

AIM: The role of platelet-derived microparticles (PDMPs) in the crosstalk between coagulopathy and inflammation in critically ill patients remains unclear. The aim of this cohort observational study was to investigate the associations between the PDMP levels and hospital mortality or disseminated intravascular coagulopathy (DIC). METHODS: This study included 119 patients who were admitted to the ICU. The PDMP levels were measured using an enzyme-linked immunosorbent assay three times a week, for a total of 372 samples. We calculated the maximum (max) PDMP value, max PDMP/platelet (PDMP/Plts) ratio (converted to the PDMP levels per 10(4) platelets) and nadir platelet count during the ICU stay. Baseline patient data and scores, including the Japanese Association for Acute Medicine (JAAM) DIC score, were collected, and potential predictors were analyzed for possible associations with hospital mortality. RESULTS: The max PDMP/Plts ratio was significantly different comparing the survivors (n=98: median, 2.54) and non-survivors (n=21: median 17.59; p<0.001). There was a weak but statistically significant negative correlation between the max PDMP level and nadir platelet count (r=-0.332, p<0.001). The max PDMP level and max PDMP/Plts ratio were higher in the DIC group (81.48 and 9.27, respectively) than in the non-DIC group (34.88 and 2.35, p=0.001 and p<0.001, respectively). The max PDMP/Plts ratio was the only variable found to be independently associated with hospital mortality according to a multivariate logistic regression analysis. CONCLUSIONS: PDMPs are involved in the development of DIC but are not related to hospital mortality. There is a good association between the PDMP/Plts ratio and hospital mortality and/or DIC in critically ill patients.

RESUMEN

PURPOSE: To compare the vision-related quality of life 5 years after Implantable Collamer Lens phakic intraocular lens (pIOL) implantation and after wavefront-guided laser in situ keratomileusis (LASIK) for myopia. SETTING: Department of Ophthalmology, Kitasato University, Kanagawa, Japan. DESIGN: Retrospective case series. METHODS: Quality of life was measured with the National Eye Institute Refractive Error Quality of Life instrument in consecutive patients 5 years after pIOL implantation or wavefront-guided LASIK to correct myopia. RESULTS: Phakic IOL implantation was performed in 48 patients and LASIK in 55 patients. The scores for activity limitations, symptoms, appearance, and satisfaction with correction were significantly higher in the pIOL group than in the LASIK group (P<.05, Mann-Whitney U test). No significant differences in other scores were observed between the 2 groups (P ≥.05). The scores for near vision and dependence on correction were significantly higher in the younger subgroup than in the older subgroup with both techniques. CONCLUSIONS: Phakic IOL implantation may offer significant vision-related quality-of-life advantages (eg, fewer activity limitations and symptoms and better appearance and satisfaction with correction) over wavefront-guided LASIK for myopia in the long term. Moreover, refractive surgery may provide a better quality of life in younger patients.

RESUMEN

Diabetic peripheral neuropathy is a major chronic diabetic complication. We have previously shown that in type 1 diabetic streptozotocin-treated mice, insulin- and TNF-α co-expressing bone marrow-derived cells (BMDCs) induced by hyperglycemia travel to nerve tissues where they fuse with nerve cells, causing premature apoptosis and nerve dysfunction. Here we show that similar BMDCs also occur in type 2 diabetic high-fat diet (HFD) mice. Furthermore, we found that hyperglycemia induces the co-expression of insulin and TNF-α in c-kit(+)Sca-1(+)lineage(-) (KSL) progenitor cells, which maintain the same expression pattern in the progeny, which in turn participates in the fusion with neurons when transferred to normoglycemic animals.
