RESUMEN

BACKGROUND: The clinical symptoms of progressive supranuclear palsy (PSP) may be mediated by aberrant dynamic functional network connectivity (dFNC). While earlier research has found altered functional network connections in PSP patients, the majority of those studies have concentrated on static functional connectivity. Nevertheless, in this study, we sought to evaluate the modifications in dynamic characteristics and establish the correlation between these disease-related changes and clinical variables. METHODS: In our study, we conducted a study on 53 PSP patients and 65 normal controls. Initially, we employed a group independent component analysis (ICA) to derive resting-state networks (RSNs), while employing a sliding window correlation approach to produce dFNC matrices. The K-means algorithm was used to cluster these matrices into distinct dynamic states, and then state analysis was subsequently employed to analyze the dFNC and temporal metrics between the two groups. Finally, we made a correlation analysis. RESULTS: PSP patients showed increased connectivity strength between medulla oblongata (MO) and visual network (VN) /cerebellum network (CBN) and decreased connections were found between default mode network (DMN) and VN/CBN, subcortical cortex network (SCN) and CBN. In addition, PSP patients spend less fraction time and shorter dwell time in a diffused state, especially the MO and SCN. Finally, the fraction time and mean dwell time in the distributed connectivity state (state 2) is negatively correlated with duration, bulbar and oculomotor symptoms. DISCUSSION: Our findings were that the altered connectivity was mostly concentrated in the CBN and MO. In addition, PSP patients had different temporal dynamics, which were associated with bulbar and oculomotor symptoms in PSPRS. It suggest that variations in dynamic functional network connectivity properties may represent an essential neurological mechanism in PSP.

RESUMEN

AIMS: To explore the psychosocial experiences during dietary management among Chinese adults with inflammatory bowel disease. DESIGN: Qualitative phenomenological design. METHODS: Eighteen adults diagnosed with inflammatory bowel disease for more than 6 months were recruited using purposive sampling from June to December 2023. Two trained researchers used van Manen's approach to analyse the data. RESULTS: The three themes with multiple subthemes emerged: facing the unknown: at a loss and aggrieved, trying to cope: uncertain and distressed, and growing in adaptation: relieved and transcendent. The first theme included unknown relapses, overlooking diet management and the absence of dietary rules. The second theme showed different coping situations, like complex dietary information and ever-closing worlds. The third theme explores how participants adapted to disease and their eating patterns. CONCLUSION: The psychosocial experiences during dietary management are complex. The accumulation of diet-related experience, acceptance of illness and social support facilitate patients in overcoming negative emotions and adhering to dietary management. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Nurses should provide tailored dietary guidance and appropriate psychological interventions to promote healthy eating in patients. IMPACT: This study may enhance healthcare professionals' understanding, particularly those in China, of the diet-related experiences among patients. REPORTING METHOD: The Consolidated Criteria for Reporting Qualitative Research checklist. PATIENT OR PUBLIC CONTRIBUTION: Participants contributed by sharing their first hand experiences.

RESUMEN

This review identified clinical practice guidelines (CPGs) and consensus statements (CSs) that include recommendations on long-term care for community-dwelling older adults. Additionally, it assessed their quality using the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool to determine high-quality guidelines and synthesis recommendations from high-quality guidelines and evaluate the quality of these guidelines using the AGREE-Recommendation Excellence (AGREE-REX) tool. A systematic search was performed (November 2023) in MEDLINE, PubMed, Guidelines International Network (GIN), National Institute for Health and Care Excellence (NICE), New Zealand Guidelines Group (NZGG), Registered Nurses' Association of Ontario (RNAO), National Guideline Clearinghouse (NGC), and Scottish Intercollegiate Guidelines Network (SIGN). Two reviewers independently selected and assessed the articles using AGREE II. A meeting was held to appraise the quality of the guidelines (AGREE II mean score >70 %) using AGREE-REX. The analysis included 14 CPGs and 2 CSs. Of these, 7 CPGs reached the standard of >70 %, the 'Scope and purpose' domain obtained the highest score with 85.43 (± 17.87), and the 'Applicability' domain scored lowest with 46.93 (± 26.74). Regarding the score of AGREE-REX, the seven CPGs were considered as 'moderate', with the 'Clinical Applicability' domain having the highest score of 61.29 % (±10.80) and the 'Values and Preferences' domain having the lowest score of 38.14 % (±9.26). Four themes were synthesised from the seven high-quality CPGs: planning and delivering person-centred home care, cognitive impairment, and screening for impaired vision and falls. The quality of CPGs and CSs on long-term care for community-dwelling older adults has room for improvement, and higher-quality guidelines are required to meet the long-term care needs of community-dwelling older adults.

RESUMEN

OBJECTIVE: Although platelet-derived growth factor receptor (PDGFR)-ß mediates the self-renewal and multipotency of neural stem/progenitor cells (NSPCs) in vitro and in vivo, its mechanisms of activating endogenous NSPCs following ischemic stroke still remain unproven. METHODS: The exogenous NSPCs were transplanted into the ischemic striatum of PDGFR-ß conditionally neuroepithelial knockout (KO) mice at 24 h after transient middle cerebral artery occlusion (tMCAO). 5-Bromo-2'-deoxyuridine (BrdU) was intraperitoneally injected to label the newly formed endogenous NSPCs. Infarction volume was measured, and behavioral tests were performed. In the subventricular zone (SVZ), proliferation of endogenous NSPCs was tested, and synapse formation and expression of nutritional factors were measured. RESULTS: Compared with control mice, KO mice showed larger infarction volume, delayed neurological recovery, reduced numbers of BrdU positive cells, decreased expression of neurogenic factors (including neurofilament, synaptophysin, and brain-derived neurotrophic factor), and decreased synaptic regeneration in SVZ after tMCAO. Moreover, exogenous NSPC transplantation significantly alleviated neurologic dysfunction, promoted neurogenesis, increased expression of neurologic factors, and diminished synaptic deformation in SVZ of FL mice after tMCAO but had no beneficial effect in KO mice. CONCLUSION: PDGFR-ß signaling may promote activation of endogenous NSPCs after postischemic NSPC transplantation, and thus represents a novel potential regeneration-based therapeutic target.

RESUMEN

BACKGROUND: Humanistic care management is a necessary measure to improve the motivation and initiative of clinical nurses and is the foundation to improve the quality of nursing. Understanding the current status and identifying the influencing factors that promote or hinder humanistic care behaviors is essential. This study investigated the current status and experiences of nurse managers' caring behaviors toward clinical nurses. METHODS: We conducted a mixed-methods study with an explanatory sequential design. A survey on the nurse managers' caring behaviors in 101 hospitals from 23 provinces and four municipalities in China was investigated (n = 2022). Then, semi-structured interviews were conducted to obtain information about the participants' experiences associated with the performance of caring behaviors (n = 27). RESULTS: Survey data demonstrated that the nurse managers' overall caring behaviors were moderately good. The total scoring rate was 88.55%, and the overall score was 161.19 ± 20.68. Qualitative data revealed that the capacity of nurse managers and clinical nurses, opportunity, and motivation to implement humanistic care are key influencing factors of caring behaviors. CONCLUSIONS: The results suggested that intrinsic motivation, organizational support, and the humanistic care capabilities of clinical nurses and nurse managers are vital to implementing care behaviors. Thus, successful humanistic care management requires a concerted effort at the individual and organizational levels.

RESUMEN

Diabetic wound treatment faces significant challenges in clinical settings. Alternative treatment approaches are needed. Continuous bleeding, disordered inflammatory regulation, obstruction of cell proliferation, and disturbance of tissue remodeling are the main characteristics of diabetic wound healing. Hydrogels made of either naturally derived or synthetic materials can potentially be designed with a variety of functions for managing the healing process of chronic wounds. Here, a hemostatic and anti-inflammatory hydrogel patch is designed for promoting diabetic wound healing. The hydrogel patch is derived from dual-cross-linked methacryloyl-substituted Bletilla Striata polysaccharide (B) and gelatin (G) via ultraviolet (UV) light. It is demonstrated that the B-G hydrogel can effectively regulate the M1/M2 phenotype of macrophages, significantly promote the proliferation and migration of fibroblasts in vitro, and accelerate angiogenesis. It can boost wound closure by normalizing epidermal tissue regeneration and depositing collagen appropriately in vivo without exogenous cytokine supplementation. Overall, the B-G bioactive hydrogel can promote diabetic wound healing in a simple, economical, effective, and safe manner.

RESUMEN

BACKGROUND: With the gradual acceleration of population ageing, social isolation in older people has increasingly become a hot topic of social concern. The reduction of valid social participation will cause older people to weaken their sense of belonging to the community and social acquisition, negatively impacting on older people's quality of life. This study is aimed to explore the main related factors affecting the social isolation of older people, so as to provide a solid scientific basis for improving the health behaviour of older people in China. METHOD: A cross-sectional study was conducted among 2267 community residents over 60 years old from four cites in Jiangsu Province, China. Perceived social support scale, Geriatric Depression Scale, Connor-Davidson Resilience Scale, Comprehensive Ability of Older People Assessment Scale and other influencing factors scales were used to investigate the current situation. Social isolation was measured with the Lubben Social Network Scale. Demographic data were evaluated using descriptive statistical analyses and relationships among study variables were determined to use a path analysis. All data were analyzed using SPSS version 22 and AMOS version 26 using T-test, analysis of variance, logistic regression analyses, and path analysis method. The test level was set at alpha = 0.05, and the difference was statistically significant at P-value <0.05. RESULTS: The results of the model test analysis indicated that the hypothesised paths were supported by data from our samples and demonstrated significance on the path coefficients (P < 0.05). Related factors in the three dimensions of social risk, economic risk and cultural risk have an impact on the social isolation of older people in the community through direct and indirect pathways, and also indirectly through the partially mediated role of depression. Overall, our hypothesised model was retained, indicating empirical support and adequate model fit indices for the theoretical model. CONCLUSION: The findings demonstrated the predictive role of related factors of social isolation in older people. In the future, we should focus on developing interventions by uniting many forces such as society, family and older people themselves to reduce social isolation among this vulnerable population and improve the quality of life of older people and promote healthy ageing.

RESUMEN

The purpose of this study was to explore the perceived unmet needs for community-based long-term care services among older urban adults in China. We analyzed the cross-sectional data of 5,201 urban community respondents ≥65 years of age from the seventh wave of the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). The chi-squared automatic interaction detection technique was used to examine the variables associated with older adults' unmet needs for four common types of community-based services: personal care, grocery shopping, home visits, and psychological consulting. We found that the majority of the older adults perceived that they needed the four services, but only 9%-27.4% of the respondents reported that their perceived needs were met. There was a high prevalence of unmet community-based service needs (51.3%-55.5%) among urban older adults in China. Factors associated with unmet needs included depression status, ADL (activities of daily living) limitations, self-rated health, number of surviving children, educational attainment, and marital status. The results suggest that policy makers should develop services targeting specific segments of the older population, increasing the adequacy of services provided.

RESUMEN

The purpose of this study was to elicit graduating undergraduate nursing students' perceived value of the work environment in aged care. Applying a cross sectional design, an electronic questionnaire was sent to 625 graduating undergraduate nursing students from three schools of nursing in Jiangsu Province, China. A discrete choice experiment questionnaire with eight choice-set questions was performed. In total, 267 nursing students (42.7%) responded to the questionnaire. We found that nursing students valued excellent working conditions the highest (OR = 3.632 [2.846~4.635]), followed by adequate formal professional development activities (OR = 2.252 [1.907~2.660]), good/excellent safety management (OR = 2.214 [1.828~2.682])/ (OR = 2.202 [1.758~2.759]), and 10% higher earnings (OR = 1.615 [1.360~1.919]). Based on these findings, the study provided information to improve the recruitment of nursing students to work with older adults. Findings suggest that students may be 44.07~73.41% more likely to choose working with older people when valued job characteristics are present.

RESUMEN

The aberrant expression of matrix metalloproteinases (MMPs) is known to contribute to the pathogenesis of airway remodeling and alveolar disruption in chronic obstructive pulmonary disease (COPD). In the discovery stage, 11 COPD from five families were subjected to whole-genome sequencing, and 21 common polymorphisms in MMPs and TIMPs were identified. These polymorphisms were genotyped in two subsequent verification studies. Of these polymorphisms, c.2392G>A (rs2664370T>C) and c.4158C>A (rs2664369T>G) in MMP16 remained significantly different. Functionally, we found that MMP16 expression was significantly increased in peripheral blood monocytes (PBMCs) from COPD and in cigarette smoke extract-treated 16HBE cells compared with controls. This was also shown by bioinformatics analysis. COPD carrying rs2664370CC showed decreased levels of MMP16 in the plasma and in PBMCs compared with those carrying CT and TT. Treatment with hsa-miR-576-5p mimics led to a greater reduction in luciferase reporter activity in cells transfected with rs2664370CC. Moreover, blood levels of base excess, PCO2 , and PO2 in COPD with rs2664370CC were significantly lower than those with rs2664370CT+TT. Taken together, these results demonstrate that the rs2664370T>C polymorphism in MMP16 protects against the risk of COPD, likely by favoring interaction with hsa-miR-576-5p, leading to reduced MMP16 expression and improved blood gas levels.

RESUMEN

Osthole (OST), a derivative of Fructus Cnidii, has been proved to have potential anti-osteoporosis effects in our recent studies. However, its pharmacological effects are limited in the human body because of poor solubility and bioavailability. Under the guidance of the classical theory of Chinese medicine, Osthole-loaded N-octyl-O-sulfonyl chitosan micelles (NSC-OST), which has not previously been reported in the literature, was synthesized in order to overcome the defects and obtain better efficacy. In this study, we found that NSC-OST inhibited on the formation and resorption activity of osteoclasts through using a bone marrow macrophage (BMM)-derived osteoclast culture system in vitro, rather than affecting the viability of cells. We also found that NSC-OST inhibited osteoclast formation, hydroxyapatite resorption and RANKL-induced osteoclast marker protein expression. In terms of mechanism, NSC-OST suppressed the NFATc1 transcriptional activity and the activation of NF-κB signalling pathway. In vivo, ovariectomized (OVX) rat models were established for further research. We found that NSC-OST can attenuate bone loss in OVX rats through inhibiting osteoclastogenesis. Consistent with our hypothesis, NSC-OST is more effective than OST in parts of the results. Taken together, our findings suggest that NSC-OST can suppress RANKL-induced osteoclastogenesis and prevents ovariectomy-induced bone loss in rats and could be considered a safe and more effective anti-osteoporosis drug than OST.

RESUMEN

Whether social contact contributes to the underlying mechanisms of depression and the observed sex differences is unclear. In this study, we subjected young male and female mice to separation- and restraint-induced stress for 4 weeks and assessed behaviors, neurotransmitter levels, hormones, and inflammatory cytokines. Results showed that, compared with controls, male mice exposed to stress displayed significant decreases in body weight and sucrose preference after 1 week. In the fourth week, they exhibited a higher degree of anxiety (open field test) and depressive-like behavior (forced swim test). Moreover, the males showed significant decreases in monoamine neurotransmitters, including norepinephrine and dopamine in striatum, and an increase in pro-inflammatory cytokines, such as tumor necrosis factor α and interleukin 1ß in serum. In contrast, females showed persistent loss of weight during stress and displayed significant decreases in sucrose preference after stress. Importantly, the females but not males showed activation of the hypothalamus-pituitary-adrenal (HPA) axis, with significantly higher levels adrenocorticotropic hormone. Additionally, mRNA level of c-fos and AVP showed there was significant interaction between stress and sex. Finally, we conclude that an imbalance of the HPA axis and inflammation might be important contributors to sex differences in separation/restraint-induced depressive behavior and that changes might be mediated by c-fos and AVP.

RESUMEN

AIM: The review aimed to evaluate the effects of pulmonary rehabilitation in elderly patients with chronic obstructive pulmonary disease (COPD). BACKGROUND: With an increase in published reports on pulmonary rehabilitation, there is a need for a meta-analysis to measure the effects of pulmonary rehabilitation in elderly COPD patients. DESIGN: A systematic review and meta-analysis. DATA SOURCES: The Cochrane library (Issue 4, 2018), Web of Science (1975 to April 2018), Embase (1974 to April 2018), Pubmed (1966 to April 2018), CINAHL (1982 to April 2018), JBI (The Joanna Briggs Institute) (1996 to April 2018), CNKI (China National Knowledge Infrastructure) (1979 to April 2018), CBM (SinoMed) (1982 to April 2018), and Wanfang Data (1900 to April 2018) were searched. REVIEW METHODS: Six outcome indicators were utilized for the effects of pulmonary rehabilitation. Two reviewers selected trials, evaluated the quality, and extracted data. Meta-analysis was performed by using the RevMan 5.3 software. RESULTS: Eight studies recruited 414 elderly patients. Pulmonary rehabilitation resulted in significantly improved exercise capacity and quality of life in elderly people but with no influence on oxygen saturation compared with the control group. CONCLUSION: There is a need to provide more detailed pulmonary rehabilitation programs for elderly patients with COPD.

RESUMEN

The effects of in vitro batch digestion on water-in-oil-in-water (W/O/W) double emulsions encapsulated with anthocyanins (ACNs) from grape skin were investigated. The double emulsions exhibited the monomodal distribution (d = 686 ± 25 nm) showing relatively high encapsulation efficiency (87.74 ± 3.12%). After in vitro mouth digestion, the droplet size (d = 771 ± 26 nm) was significantly increased (p < 0.05). The double W1/O/W2 emulsions became a single W1/O emulsion due to proteolysis, which were coalesced together to form big particles with significant increases (p < 0.01) of average droplet sizes (d > 5 µm) after gastric digestion. During intestinal digestion, W1/O droplets were broken to give empty oil droplets and released ACNs in inner water phase, and the average droplet sizes (d < 260 nm) decreased significantly (p < 0.05). Our results indicated that ACNs were effectively protected by W/O/W double emulsions against in vitro mouth digestion and gastric, and were delivered in the simulated small intestine phase.

RESUMEN

Blueberry pomace is a rich source of high-value bioactive polyphenols with presumed health benefits. Their incorporation into functional foods and health-related products benefits from coencapsulation and protection of polyphenol-rich extracts in suitable carriers. This study aimed to create a water-in-oil-in-water (W1/O/W2) double emulsion system suitable for the coencapsulation of total phenolics (TP) and anthocyanins (TA) from a polyphenol-rich extract of blueberry pomace (W1). The effect of critical physical parameters for preparing stable double emulsions, namely homogenization pressure, stirring speed and time, was investigated by measuring the hydrodynamic diameter, size dispersity and zeta potential of the oil droplets, and the encapsulation efficiency of TP and TA. The oil droplets were negatively charged (negative zeta potential values), which was related to the pH and composition of W2 (whey protein isolate solution) and suggests stabilization by the charged whey proteins. Increasing W1/O/W2 microfluidization pressure from 50 to 200 MPa or homogenization speed from 6000 to 12,000 rpm significantly increased droplet diameter and zeta potential and decreased TA and TP encapsulation efficiency. Increasing W1/O/W2 homogenization time from 15 to 20 min also increased droplet diameter and zeta potential and lowered TA encapsulation efficiency, while TP encapsulation did not vary significantly. In contrast, increasing W1/O homogenization time from 5 to 10 min at 10,000 rpm markedly increased TA encapsulation efficiency and reduced droplet diameter and zeta potential. High coencapsulation rates of blueberry polyphenols and anthocyanins around 80% or greater were achieved when the oil droplets were relatively small (mean diameter < 400 nm), with low dispersity (<0.25) and a high negative surface charge (-40 mV or less). These characteristics were obtained by homogenizing for 10 min at 10,000 rpm (W1/O), then 6000 rpm for 15 min, followed by microfluidization at 50 MPa.

RESUMEN

The current prototype patient classification system in China has not been updated for over six decades. In the present study, we adopted a hybrid patient classification method using both disease severity and activities of daily living scores to classify patients. The time motion approach was used to measure the direct nursing time of 551 general acute care patients. We found that patients in old Categories according to ability of self-care and disease severity 1-4 received approximately 7.1, 4.6, 3.4, and 4.5 h of direct nursing care, and the number of hours was not significantly different between Categories 2, 3, and 4. In contrast, patients in new Categories 1-4 received approximately 10.1, 6.9, 4.4, and 2.4 h of direct nursing care in 24 h. The nursing hours were significantly different between all pairings of the new categories. The new classification system can be used to make nursing care assignments and adjust staffing.

RESUMEN

To evaluate the epidemiological characteristics, reporting characteristics, and methodological quality of systematic reviews in the traditional Chinese medicine nursing field published in Chinese journals. The number of systematic reviews in the traditional Chinese medicine nursing field has increased, but their epidemiology, quality, and reporting characteristics have not been assessed completely. We generated an overview of reviews using a narrative approach. Four Chinese databases were searched for systematic reviews from inception to December 2015. The Preferred Reporting Items of Systematic Reviews and Meta-analyses and the Assessment of Multiple Systematic Reviews checklists were adopted to evaluate reporting and methodological quality, respectively. A total of 73 eligible systematic reviews, published from 2005 to 2015, were included. The deficiencies in reporting characteristics mainly lay in the lack of structured abstract or protocol, incomplete reporting of search strategies, study selection, and risk of bias. The deficiencies in methodological quality were reflected in the lack of a priori design and conflict of interest, incomplete literature searches, and assessment of publication bias. The quality of the evaluated reviews was unsatisfactory; attention should be paid to the improvement of reporting and methodological quality in the conduct of systematic reviews.

RESUMEN

OBJECTIVE: To analyze document features and current research status of applying proteomics technology in acupuncture and moxibustion research, thereby further providing reference for further research and development in this area. METHODS: CNKI, Wangfang Data, CBM, PubMed, and Medline were included. Retrieved were literatures involving applying proteomics technology in acupunc- ture and moxibustion from January 2004 to December 2015. Document features and current research features were statistically analyzed using bibliometrics. RESULTS: Totally 91 articles were included, 60 from journals, 8 conference theses, and 23 dissertations. The 60 articles were published in 47 kinds of journals, and 56 of them were published in core journals. Theories of acupuncture and moxibustion (correlated with meridians, zang-fu organs) and mechanism research were hotspots, involving 19 kinds of disease models (dominated as gastric mucosal lesion, cerebral ischemia, and spinal cord injury). Two- dimensional gel based electrophoresis technology was used in 51 articles (69. 86%). CONCLUSIONS: Proteomics technology has been widely applied in the field of acupuncture and moxibustion research. It could promote researches on meridians and zang-fu organs correlated theories and mechanisms. The depth and breadth of the study is worth further widening.

RESUMEN

Pathological Jaundice on neonate differs from that of physiologic jaundice. They perform differently on clinical cases, which is an effective way to distinguish them. There are many causes for pathological jaundice, common ones include hemolytic jaundice, infectious jaundice, obstructive jaundice, breast-feeding jaundice, etc. Clinically proven that pathological jaundices has significant differences in symptoms. This brings problems to its treatment and nursing. In recent years, TCM comprehensive nursing shows great results in treating process. Therefore, this paper take 2000 cases to make a thorough analysis for the actual clinical effects of TCM comprehensive nursing on pathological jaundice on neonate.

RESUMEN

PURPOSE: To evaluate long-term, longitudinal displacement of the optic nerve head (ONH) and anterior lamina cribrosa surfaces in glaucoma patients imaged with spectral-domain optical coherence tomography (SD OCT). DESIGN: Prospective study. PARTICIPANTS: A total of 173 eyes of 108 subjects (88 with glaucoma and 20 normal subjects) followed for a mean of 5.3 years. METHODS: The optic disc was imaged with SD OCT at approximately 4-month intervals, and the ONH surface depth (ONHSD), anterior lamina cribrosa surface depth (ALCSD), and prelaminar tissue thickness (PTT) were measured. The reproducibility coefficients of ONHSD, ALCSD, and PTT were calculated from 2 baseline measurements of the glaucoma group. Change in ONHSD/ALCSD/PTT was confirmed when the differences between the first baseline and the latest 2 consecutive follow-up visits were greater than the corresponding reproducibility coefficient. Factors associated with ONHSD and ALCSD changes were identified with linear mixed modeling. MAIN OUTCOME MEASURES: Proportion of eyes with ONHSD/ALCSD change. RESULTS: Within the glaucoma group, 23.9% (33 eyes) had confirmed ONHSD change (15.2% with posterior and 8.7% with anterior displacement) and 24.6% (34 eyes) had confirmed ALCSD change (12.3% with posterior and 12.3% with anterior displacement). Some 9.4% (13 eyes) showed a decrease in PTT, and 2.2% (3 eyes) showed an increase in PTT. The specificity for detection of ONHSD/ALCSD/PTT change was 91.4% (95% confidence interval [CI], 77.6-97.0), 82.9% (95% CI, 67.3-91.9), and 94.3% (95% CI, 81.4-98.4), respectively. There were no significant differences in the proportion of eyes with visual field progression or history of filtration surgery between the groups with anterior and posterior displacement of ONH/anterior laminar surfaces (P ≥ 0.678). For each millimeter of mercury increase in the average intraocular pressure (IOP) during follow-up, the ONH and anterior laminar surfaces displaced posteriorly by 1.6 µm and 2.0 µm, respectively. An older age was associated with a decrease in magnitude of posterior displacement of the ONH and anterior laminar surfaces (P ≤ 0.009). CONCLUSIONS: The ONH and anterior laminar surfaces displaced not only posteriorly but also anteriorly (with reference to Bruch's membrane opening) in a significant portion of glaucoma patients. The magnitude of change was related to age and the averaged IOP during follow-up.
