Fight Retinal Blindness SPAIN. Report 3: clinical outcomes of vascular endothelial growth factor inhibitors in low vision eyes with neovascular age-related macular degeneration. A national database study.

OBJECTIVES: To compare visual outcomes for low vision eyes (LVE) (<35 letters LogMAR or <20/200 Snellen) versus non-low vision eyes (NLVE) (>35 letters LogMAR or >20/200 Snellen) at the time of the first injection in a clinical practice setting. METHODS: Subgroup analysis of a multicenter national database of treatment- naïve eyes neovascular age related macular degeneration (nAMD) treated with anti-VEGF intravitreal injections divided into LVE and NLVE. Demographics, visual acuity (VA) at baseline and subsequent timepoints (12, 24, and 36 months), number of injections and visits data were collected using a validated web-based tool (Fight Retinal Blindness!). RESULTS: 3138 eyes were included, 705 LVE and 2433 NLVE. The LVE group had the greatest VA gain (p < 0.001), at 12, 24, and 36 months (+15, +15, and +13 letters respectively). The proportion of patients with VA loss (-5 letters) differed between groups at 12, 24, and 36 and was significantly greater (p < 0.001) in NLVE. The proportion of patients with VA gain (+5 letters) was significantly higher (p < 0.001) in LVE in all timeframes. The proportions of LVE that still had VA ≤ 35 letters at 12, 24, and 36 months were 54%, 54%, and 57%. Conversely, 8%, 9%, and 8% of LVE achieved VA ≥ 70 letters at 12, 24, and 36 months. LVE received fewer intravitreal injections than NLVE throughout follow-up (6, 9, 12 vs 7, 11, 15). CONCLUSION: Findings of this study support the need for ongoing therapy in patients with initial visual acuity less than 35 letters since sustained visual improvements can be achieved and maintained for the first 3 years of treatment.

Case report: Bilateral optic nerve sheath meningocele: clinical aspects.

Optic nerve sheath meningocele is an enlargement of the sheath itself, consisting of a collection of cerebrospinal fluid along the perineural space. It should be considered primary if it is not associated with orbital-cerebral neoplasm or with cranio-orbital junction malformations. We report three cases of bilateral primary idiopathic optic nerve sheath meningocele, two of them with gradual vision loss. The first case presented a history of monocular blurred vision of the right eye and headache. It was initially treated with acetazolamide without any improvement, after which optic nerve sheath fenestration was required. The second case showed intermittent binocular diplopia with central 24-2 perimetry defects in the left eye. The third case was first presented as a subacute bilateral conjunctivitis with a suspected orbital pseudotumor. An incidental bilateral optic nerve sheath meningocele was found in the orbital imaging, being totally asymptomatic. In all the cases, orbital and cranial magnetic resonance with contrast and fat suppression was crucial in the diagnosis.

Psychosocial predictors of health behavior adherence in heart-failure patients with comorbid depression: a secondary analysis of the Hopeful Heart trial.

BACKGROUND: Depression affects 20-30% of individuals with heart failure (HF), and it is associated with worse health outcomes independent of disease severity. One potential explanation is the adverse impact of depression on HF patients' adherence to the health behaviors needed to self-manage their condition. The aim of this study is to identify characteristics associated with lower adherence in this population, which could help to recognize individuals at higher risk and eventually tailor health behavior interventions to their needs. METHODS: Using data from a randomized, controlled, collaborative care treatment trial in 629 patients with HF and comorbid depression, we performed mixed effects logistic regression analyses to examine the cross-sectional and prospective relationships between medical and psychosocial variables and health behavior adherence, including adherence to medications, a low-sodium diet, and physician appointments. RESULTS: In cross-sectional analyses, married marital status and higher physical health-related quality of life (HRQoL) were associated with greater overall adherence (compared to married, single Odds Ratio [OR] = 0.46, 95% Confidence Interval [CI] = 0.26-0.80; other OR = 0.60, CI = 0.38-0.94; p = .012. Physical HRQoL OR = 1.02, CI = 1.00-1.04, p = .047). Prospectively, greater levels of social support were associated with improved overall adherence one year later (OR = 1.04, 95% CI = 1.00-1.08, p = .037). Social support, HF symptom severity, race and ethnicity, and age were predictors of specific types of adherence. Neither depression nor optimism was significantly associated with adherence outcomes. CONCLUSIONS: These results provide important preliminary information about risk factors for poor adherence in patients with both HF and depression, which could, in turn, contribute to the development of interventions to promote adherence in this high-risk population.

An adaptive text message intervention to promote psychological well-being and reduce cardiac risk: The Text4Health controlled clinical pilot trial.

OBJECTIVE: In a two-arm pilot trial, we examined the feasibility, acceptability, and preliminary efficacy of a 12-week, adaptive text message intervention (TMI) to promote health behaviors and psychological well-being in 60 individuals with multiple cardiac risk conditions (i.e., hypertension, hyperlipidemia, and/or type 2 diabetes) and suboptimal adherence to exercise or dietary guidance. METHODS: Participants were allocated to receive the TMI or enhanced usual care (eUC). The TMI included daily adaptive text messages promoting health behaviors, twice-weekly messages to set goals and monitor progress, and monthly phone check-ins. Feasibility (primary outcome) and acceptability were measured by rates of successful text message delivery and daily participant ratings of message utility (0-10 Likert scale). We also assessed impact on health behavior adherence, psychological health, and functional outcomes. RESULTS: The TMI was feasible (99.3% of messages successfully sent) and well-accepted (mean utility = 7.4/10 [SD 2.6]). At 12 weeks, the TMI led to small-sized greater improvements in moderate to vigorous physical activity (d = 0.37), overall physical activity (d = 0.23), optimism (d = 0.20), anxiety (d = -0.36), self-efficacy (d = 0.22), and physical function (d = 0.20), compared to eUC. It did not impact other outcomes substantially at this time point. CONCLUSION: This 12-week, adaptive TMI was feasible, well-accepted, and associated with small-sized greater improvements in health behavior and psychological outcomes. Though larger studies are needed, it has the potential to be a scalable, low-intensity program that could be used in clinical practice. CLINICALTRIALS: govregistration:NCT04382521.

Macular Neovascularization Type Influence on Anti-VEGF Intravitreal Therapy Outcomes in Age-Related Macular Degeneration.

PURPOSE: To evaluate the influence of macular neovascularization (MNV) lesion type on 12-month clinical outcomes in treatment-naive eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF drugs nationwide. DESIGN: Multicenter national nAMD database observational study. SUBJECTS: One thousand six hundred six treatment-naive nAMD eyes (1330 patients) undergoing anti-VEGF therapy for 12 months nationwide. METHODS: Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution letters, number of injections and visits were was collected using a validated web-based tool. Neovascular lesion phenotype was classified as type 1 (T1, n = 711), type 2 (T2, n = 505), type 3 (T3, n = 315), and aneurysmal type 1 (A-T1, n = 75), according to the new proposed consensus classification. MAIN OUTCOME MEASURES: Mean VA change at 12 months, final VA at 12 months, number of injections, time to lesion inactivation. RESULTS: A total of 1606 treatment-naive nAMD eyes (1330 patients) received a median of 7 injections over 12 months. Mean (± standard deviation) baseline VA was significantly lower for T2 (49.4 ± 23.5 letters) compared with T1 (57.8 ± 20.8) and T3 (58.2 ± 19.4) (both P < 0.05) lesions. Mean VA change at 12 months was significantly greater for A-T1 (+9.5 letters) compared with T3 (+3.1 letters, P < 0.05). Patients with T3 lesions had fewer active visits (24.9%) than those with other lesion types (T1, 30.5%; T2, 32.6%; A-T1, 27.5%; all P < 0.05). Aflibercept was the most used drug in A-T1 lesions (70.1%) and ranibizumab in T1 (40.7%), T2 (57.7%), and T3 (47.6%) lesions. CONCLUSIONS: This study highlights the relevance of MNV type on clinical outcomes in nAMD and reports significant differences in baseline VA, VA change, and lesion activity at 12 months. This report provides data about lesion-specific clinical features, which may guide the management of nAMD cases and potentially support personalized clinical decision making for these patients.

Artificial intelligence-based fluid quantification and associated visual outcomes in a real-world, multicentre neovascular age-related macular degeneration national database.

AIM: To explore associations between artificial intelligence (AI)-based fluid compartment quantifications and 12 months visual outcomes in OCT images from a real-world, multicentre, national cohort of naïve neovascular age-related macular degeneration (nAMD) treated eyes. METHODS: Demographics, visual acuity (VA), drug and number of injections data were collected using a validated web-based tool. Fluid compartment quantifications including intraretinal fluid (IRF), subretinal fluid (SRF) and pigment epithelial detachment (PED) in the fovea (1 mm), parafovea (3 mm) and perifovea (6 mm) were measured in nanoliters (nL) using a validated AI-tool. RESULTS: 452 naïve nAMD eyes presented a mean VA gain of +5.5 letters with a median of 7 injections over 12 months. Baseline foveal IRF associated poorer baseline (44.7 vs 63.4 letters) and final VA (52.1 vs 69.1), SRF better final VA (67.1 vs 59.0) and greater VA gains (+7.1 vs +1.9), and PED poorer baseline (48.8 vs 57.3) and final VA (55.1 vs 64.1). Predicted VA gains were greater for foveal SRF (+6.2 vs +0.6), parafoveal SRF (+6.9 vs +1.3), perifoveal SRF (+6.2 vs -0.1) and parafoveal IRF (+7.4 vs +3.6, all p<0.05). Fluid dynamics analysis revealed the greatest relative volume reduction for foveal SRF (-16.4 nL, -86.8%), followed by IRF (-17.2 nL, -84.7%) and PED (-19.1 nL, -28.6%). Subgroup analysis showed greater reductions in eyes with higher number of injections. CONCLUSION: This real-world study describes an AI-based analysis of fluid dynamics and defines baseline OCT-based patient profiles that associate 12-month visual outcomes in a large cohort of treated naïve nAMD eyes nationwide.

A novel health behaviour intervention to promote adherence in kidney failure.

BACKGROUND: Health behaviour adherence is associated with improved survival in kidney failure (KF); however, most patients with KF do not adhere to one or more health behaviours. Existing health behaviour interventions have significant limitations and do not focus on psychological factors that are associated with adherence and health. OBJECTIVES: To examine the feasibility, acceptability, and preliminary efficacy of a 12-week, phone-delivered, positive psychology-motivational interviewing (MI) intervention to promote psychological well-being and adherence in KF. DESIGN: Single-arm, proof-of-concept trial (N = 10). PARTICIPANTS: Participants were adults with KF undergoing haemodialysis and reporting suboptimal adherence to physical activity, diet, and/or medications. Participants attended weekly phone sessions with a study trainer, completed weekly positive psychology exercises (focused on gratitude, strengths, and meaning), and worked towards physical activity, diet, and/or medication goals. MEASUREMENTS: Feasibility was measured by the percentage of sessions completed, while acceptability was assessed through participant ratings of positive psychology and MI session ease and utility (0-10 Likert scales). We explored the intervention's impact on psychological outcomes and health behaviour adherence using validated scales and accelerometers. RESULTS: Participants completed 78% of sessions and rated the program's components as easy to complete (positive psychology: 8.7 ± 1.5; MI: 8.3 ± 2.0) and subjectively helpful (positive psychology: 8.8 ± 1.2; MI: 8.8 ± 1.6). The intervention led to promising but nonsignificant improvements in psychological and adherence measures. CONCLUSIONS: This 12-week, phone-delivered program was feasible, well-accepted, and associated with nonsignificant improvements health behaviour adherence, highlighting the need for a larger efficacy trial.

Scribble basal polarity acquisition in RPE cells and its mislocalization in a pathological AMD-like model.

Apicobasal polarity is a hallmark of retinal pigment epithelium cells and is required to perform their functions; however, the precise roles of the different proteins that execute polarity are still poorly understood. Here, we have studied the expression and location of Scribble, the core member of the polarity basal protein complex in epithelial-derived cells, in human and mouse RPE cells in both control and pathological conditions. We found that Scribble specifically localizes at the basolateral membrane of mouse and human RPE cells. In addition, we observed an increase in the expression of Scribble during human RPE development in culture, while it acquires a well-defined basolateral pattern as this process is completed. Finally, the expression and location of Scribble were analyzed in human RPE cells in experimental conditions that mimic the toxic environment suffered by these cells during AMD development and found an increase in Scribble expression in cells that develop a pathological phenotype, suggesting that the protein could be altered in cells under stress conditions, as occurs in AMD. Together, our results demonstrate, for the first time, that Scribble is expressed in both human and mouse RPE and is localized at the basolateral membrane in mature cells. Furthermore, Scribble shows impaired expression and location in RPE cells in pathological conditions, suggesting a possible role for this protein in the development of pathologies, such as AMD.

Latent growth curve modeling of physical activity trajectories in a positive-psychology and motivational interviewing intervention for people with type 2 diabetes.

BACKGROUND: Physical activity is critical for preventing and treating Type 2 diabetes (T2D). It is important to identify different profiles of physical activity change among those participating in behavioral interventions to optimize intervention-person fit. METHODS: This study analyzes longitudinal trajectories of change in moderate-to-vigorous physical activity (MVPA) in a positive psychology (PP) and motivational interviewing (MI) intervention for T2D, using latent growth curve modeling (LGCM). Objective measures of MVPA were collected using accelerometers at three time points: pre-intervention, immediately post-intervention, and eight weeks post-intervention. LGCM analyses identified subpopulations of participants who responded similarly to the intervention and examined if sociodemographic, medical and psychosocial characteristics were associated with MVPA trajectories. RESULTS: Analyses included 47 participants with complete follow-ups: 49% male, 81% non-Hispanic white, average age 66.1 (SD = 10.1). Overall, 36% of the participants increased MVPA while 57% did not. LGCM identified three profiles with distinct MVPA trajectories. Profile 1 ('Started Low, No Change'; 65.8% of participants) with a starting mean of 4.54 min of MVPA/day and decreased by -3.36 min. Profile 2 ('Moderate-High Start, Minimal Change,' 27.4% of participants) and had a starting mean of 22.86 min/day of MVPA with an average increase of 1.03 min. Profile 3 ('Moderate Start, Ended High'; 6.8% of participants), had a starting mean of 7.33 min MVPA/day, and increased by 28.4 min. Being male, younger, having fewer medical and psychiatric comorbidities were associated with increases in MVPA. CONCLUSIONS: This secondary analysis detected three distinct physical activity profiles during and after a PP-MI intervention. Future interventions can target individuals with characteristics that showed the greatest benefit and add additional supports to people in groups that did not increase physical activity as much. These findings show a need for targeted and sustained behavior change strategies during and after physical activity interventions. Trial registration: ClinicalTrials.gov; identifier: NCT03001999.

A phone and text message intervention to improve physical activity in midlife: initial feasibility testing.

Background: Physical activity during midlife (ages 45-64) plays a major role in the prevention of chronic and serious medical conditions. Unfortunately, many midlife adults struggle to be physically active in the setting of low levels of psychological well-being and the management of multiple confluent sources of stress. Effective, scalable, midlife-specific interventions are needed to promote physical activity and prevent the development of chronic medical conditions. Objectives: In an initial proof-of-concept trial, we assessed the feasibility and acceptability of a new, midlife-adapted, phone- and text message-based intervention using positive psychology (PP) skill-building and motivational interviewing (MI) techniques. We secondarily analyzed post-intervention changes in accelerometer-measured physical activity and self-reported outcomes. Methods: The PP-MI intervention included six weekly phone sessions with a study trainer, with completion of PP activities and physical activity goals between calls, and in the subsequent six weeks briefer phone check-ins were conducted. Text messages over the 12-week intervention period were utilized to support participants and identify barriers to goal completion. Feasibility (session completion rates) and acceptability (participant ratings of intervention ease and utility) were assessed via descriptive statistics, and pre-post improvements in psychological, functional, and physical activity outcomes at 12 weeks were examined via mixed effects regression models. Results: Twelve midlife adults with low baseline physical activity enrolled in the single-arm trial. Overall, 76.8% of all possible sessions were completed by participants, and mean ratings of weekly phone sessions were 8.9/10 (SD 1.6), exceeding our a priori thresholds for feasibility and acceptability. Participants demonstrated generally medium to large effect size magnitude improvements in accelerometer-measured physical activity, psychological outcomes, and function. Conclusions: A novel, midlife-specific phone- and text-based PP-MI intervention was feasible and had promising effects on physical activity and other clinically relevant outcomes, supporting next-step testing of this program via a randomized controlled trial.

Creation of a neovascular age-related macular degeneration national database using a web-based platform: Fight Retinal Blindness Spain. Report 1: Visual outcomes.

BACKGROUND: To study the visual outcomes of neovascular AMD (nAMD) treated with anti-vascular endothelial growth factor (VEGF) drugs at national level. METHODS: Multicenter national database of nAMD eyes treated with anti-VEGF intravitreal injections (ranibizumab, aflibercept, bevacizumab) in fixed bimonthly (FB) or treat-and-extend (TAE) regimens. Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution (logMAR) ETDRS letters at baseline and subsequent visits, number of injections and visits data were collected using a validated web-based tool (Fight Retinal Blindness!). RESULTS: 1273 eyes (1014 patients) were included, 971 treatment naïve (TN) and 302 previously treated (PT). Baseline VA (mean ± SD) was 57.5 (±19.5) and 62.2 (±17) (p > 0.001), and 24 months final VA was 60.4 (±21.2) and 58.8 (±21.1) (p = 0.326), respectively. Mean VA change at 12/24 months was +4.2/+2.9 letters in TN eyes and +0.1/-3.4 letters in PT eyes (p < 0.001/p < 0.001). The percentage of ≥15 letters gainers/losers at 24 months was 24.8%/14.5% in TN, and 10.3%/15.7% in PT eyes. The median number of injections/visits at 12 months was 7/9 in TN and 6/8 in PT (p = 0.002/p < 0.001) and at 24 months was 11/16 in TN and 11/14 in PT (p = 0.329/p < 0.001). Study drugs included ranibizumab (39.5%), aflibercept (41.2%) and bevacizumab (19.3%). CONCLUSION: Independent, large-scale national audits are feasible if committed health care professionals are provided with efficient information technology systems to do them. The results described here represent an adequate measurement of the quality of care delivered nationwide and benchmark the clinical management of nAMD at a country level compared to other real-world international cohorts.

The role of positive psychological constructs in diet and eating behavior among people with metabolic syndrome: A qualitative study.

Positive Psychological (PP) constructs (e.g., optimism and gratitude) may impact the adherence to healthy behaviors, including diet, though prior studies have shown mixed findings. This qualitative study explored the relationships between PP constructs and dietary behaviors among 21 adults with metabolic syndrome through semi-structured interviews. Directed content analysis led to five themes: eating healthfully leads to PP constructs, PP constructs lead to eating healthfully, eating healthfully prevents negative emotions, healthy behaviors associated with diet, and an upward healthy spiral. Given the close relationship between PP constructs and diet, these may be targeted to improve diet in risk populations through interventions that promote well-being.

Anti-TNF-alpha-induced lupus in patients with non-infectious uveitis.

PURPOSE: Anti-TNF-α-induced lupus (ATIL) is a rare condition considered as a drug-induced lupus (DIL) in patients under anti-TNF-α therapies. Nowadays it is still unclear if ATIL is a classical DIL or represent a distinct syndrome. Some characteristics of DIL have been described specifically associated with patients with lupus-like syndrome receiving anti-TNF-α therapy: the severity of the disease, incidence/prevalence of dsDNA antibodies (anti-dsDNA) and hypocomplementaemia. The objective of this study is to describe the development of ATIL in patients with non-infectious uveitis in a single tertiary center. METHODS: Retrospective description of a case series. RESULTS: We describe three patients with noninfectious uveitis (NIU) of different etiologies who developed antinuclear antibody (ANA) and anti-dsDNA antibody positivity, arthritis and, in one case, skin lesions under adalimumab treatment. The condition resolved in all of them after adalimumab withdrawal. Corticosteroids were required in one patient, non-steroidal anti-inflammatory drugs in two patients, and hydroxychloroquine in one of them. None required another immunosuppressive drug. A subsequent control of the NIU could continue to be carried out without anti-TNF-α therapy in two patients and in the remaining a switch was made to another anti-TNF-α (golimumab). CONCLUSION: The current report describes three cases of ATIL in patients with different types of NIU which share some common features: ANA positivity, articular symptoms, and a temporal relationship between symptoms onset and anti-TNF-α treatment. A review of the literature and comparison with the few previous reported ATIL cases was conducted as well.

A Psychological-Behavioral Intervention to Improve Physical Activity in Midlife Adults With Low Baseline Physical Activity.

Background: Many midlife adults (aged 45-64 years) struggle to become physically active in the context of diminished psychological well-being and multiple concurrent stressors, despite the clear association of low physical activity with the development of chronic medical conditions.Objectives: To assess the feasibility (rates of session completion) and acceptability (participant 0-10 ratings of weekly session ease and utility) of a novel 12-week, phone-delivered, midlife-adapted positive psychology-motivational interviewing (PP-MI) intervention to promote physical activity. Secondary aims were pre-post changes in accelerometer-measured physical activity and self-reported psychological and functional measures.Methods: A single-arm proof-of-concept trial of the PP-MI intervention was conducted among 11 inactive midlife adults enrolled from the primary care practices of an urban academic medical center. Descriptive statistics were used to assess feasibility and acceptability outcomes, and mixed effects models were used to examine pre-post changes in psychological, functional, and physical activity outcomes from baseline to 12 weeks.Results: The intervention exceeded a priori thresholds for feasibility and acceptability, with 80.3% session completion across all participants and mean session ratings of 8.3/10 (SD = 2.1). Participants also had medium effect size magnitude improvements in physical activity and psychological outcomes.Conclusions: This remotely delivered, midlife-specific PP-MI intervention was feasible and well-accepted among inactive midlife adults, supporting next-step testing of this program in a randomized trial.Trial Registration: ClinicalTrials.gov identifier: NCT04745182.

An Adaptive Text Message Intervention to Promote Well-Being and Health Behavior Adherence for Patients With Cardiovascular Disease: Intervention Design and Preliminary Results.

BACKGROUND: Most individuals with heart disease struggle to adhere to cardiovascular health behaviors, despite their known health benefits. Text message interventions (TMIs) are a promising treatment modality for health behavior promotion, but existing TMIs typically deliver a fixed set of messages and do not target well-being constructs associated with adherence and cardiovascular health. OBJECTIVE: To develop a 4-week TMI, which delivers daily messages to promote well-being and adherence to health behaviors and dynamically adapts based on participant feedback to deliver increasingly customized messages; and to assess its feasibility, acceptability, and preliminary efficacy in a single-arm, proof-of-concept trial in 14 individuals with coronary artery disease (age mean = 67.9, standard deviation = 8.7). METHODS: Participants received daily text messages related to well-being, physical activity, or diet, rated each message's utility, and these ratings informed the TMI's choice of future text messages. Feasibility was assessed by the proportion of messages successfully sent, and acceptability was assessed by participant ratings of intervention burden and text message utility. Finally, the intervention's preliminary efficacy was explored by measuring pre-post changes in psychologic and behavioral outcomes. RESULTS: The TMI was both feasible (93% of participants received all messages) and well-accepted (mean text message utility: 7.0 of 10 [standard deviation 2.5]; mean intervention utility: 6.4 of 10 [standard deviation 0.9]; mean intervention burden: 0.5 of 10 [standard deviation 0.9]). Participants reported that messages related to well-being were particularly helpful and that most messages led to an action (e.g., eating more vegetables, being kind to others). The TMI led to nonsignificant, small-to-medium effect size improvements in happiness, optimism, determination, depression, anxiety, self-rated health, and diet (d = 0.19-0.48), and, unexpectedly, small reductions in activity and physical function (d = -0.20 and -0.32). CONCLUSIONS: The adaptive TMI was feasible, well-accepted, and associated with nonsignificant improvements in psychologic outcomes and mixed effects on behavioral outcomes. Larger, well-powered studies are needed to determine whether this TMI will be able to improve well-being and health-related outcomes in this high-risk population.

Late Onset Macular Oedema in a Patient with Multiple Sclerosis Treated with Fingolimod.

Macular oedema is a rare complication of fingolimod treatment. It usually presents within 3-4 months, but occasionally presents later. It can resolve without treatment despite continuation of fingolimod treatment. Herein we report a case of very late onset macular oedema in a 49-year-old woman with multiple sclerosis treated with fingolimod for 7 years. The patient presented with blurred vision in both eyes with visual acuities of 20/32 in her right eye and 20/25 in her left eye. She had macular oedema, that without discontinuing fingolimod treatment, resolved after 1 month.

Treat-and-extend versus fixed bimonthly treatment regimens for treatment-naive neovascular age-related macular degeneration: real world data from the Fight Retinal Blindness registry.

PURPOSE: To compare the outcomes of two different antivascular endothelial growth factor treatment regimens for treatment-naive eyes with neovascular age-related macular degeneration in routine clinical care at 12 and 24 months in Spain. METHODS: Observational study using the Fight Retinal Blindness (FRB) outcomes registry platform. Eyes were treated with fixed bimonthly (FB) aflibercept group at one center and a treat-and-extend (TAE) regimen using either aflibercept or ranibizumab at the other center. RESULTS: We included 192 eyes. Of these, 160 eyes (83%) completed 12 months (86 TAE and 74 FB) and 79 (41%) completed 24 months (46 for TAE and 33 for FB) of follow-up. No statistically significant differences (p > 0.05) were found regarding mean visual acuity (VA, logMAR letters) at baseline (12 month cohort TAE 59.6 vs FB 57.9; 24 month cohort TAE 61.7 vs FB 62.6), final mean VA (12 month cohort TAE 61.1 vs FB 63.0; 24 month cohort TAE 64.8 vs FB 66.4), and median number of injections (12 months TAE 7 vs FB 7; 24 months TAE 11 vs FB 12). However, the distribution of injection frequencies for the TAE group was larger, with 35% of TAE eyes receiving ≤ 6 injections at 12 months compared with only 19% of FB eyes (p = 0.024). CONCLUSION: Similar VA results were observed with TAE and FB regimens, with no differences in the median number of injections. However, the TAE approach seemed to deliver a wider distribution of injection frequencies due to its individualized approach, which may help reduce the burden of injections in some eyes.

Effects of the Best Possible Self intervention: A systematic review and meta-analysis.

The Best Possible Self (BPS) exercise promotes a positive view of oneself in the best possible future, after working hard towards it. Since the first work that attempted to examine the benefits of this intervention in 2001, studies on the BPS have grown exponentially and, currently, this is one of the most widely used Positive Psychology Interventions. However, little is yet known about its overall effectiveness in increasing wellbeing outcomes. Thus, the aim of this meta-analysis is to shed light on this question. A systematic literature search was conducted, and 29 studies (in 26 articles) met the inclusion criteria of empirically testing the intervention and comparing it to a control condition. In addition, BPS was compared to gratitude interventions in some of the included studies. A total of 2,909 participants were involved in the analyses. The outcome measures were wellbeing, optimism, depressive symptoms, and positive and negative affect. Results showed that the BPS is an effective intervention to improve wellbeing (d+ = .325), optimism (d+ = .334) and positive affect (d+ = .511) comparing to controls. Small effect sizes were obtained for negative affect and depressive symptoms. Moderator analyses did not show statistically significant results for wellbeing, except for a trend towards significance in the age of the participants (years) and the magnitude of the intervention (total minutes of practice). In addition, the BPS was found to be more beneficial for positive and negative affect than gratitude interventions (d+ = .326 and d+ = .485, respectively). These results indicate that the BPS can be considered a valuable Positive Psychology Intervention to improve clients' wellbeing, and it seems that it might be more effective for older participants and with shorter practices (measured as total minutes of practice).

Qualitative analysis of the Best Possible Self intervention: Underlying mechanisms that influence its efficacy.

BACKGROUND: The Best Possible Self is a Positive Psychology Intervention which asks participants to write down about themselves in their best possible future. Previous studies have shown its efficacy to enhance wellbeing, but the mechanisms that underlie its efficacy are still unknown. OBJECTIVE: The aim of this study was to analyze the content of the essays of the BPS intervention and to examine how this content was related to the efficacy of the intervention to increase positive affect. METHOD: Participants (N = 78) were randomized to either the Best Possible Self condition, or one of two variants of the intervention: one's best self in the present, and one's best self in the past. Qualitative analyses of the texts were carried out to explore the main themes and features of the essays. Then, a mixed-methods approach with quantitative and qualitative data was followed, in order to analyze the relationship between the content of the texts and the change in positive affect produced by the interventions. RESULTS: Significant differences between conditions were found in the content of the compositions. Regression analyses showed that different variables predicted the change in positive affect depending on the condition. Mediation analyses also found differences among conditions. CONCLUSIONS: These findings suggest that these interventions respond to different underlying mechanisms which influence their efficacy. This study contributed to a better understanding of how Positive Psychology Interventions work, and how to increment their efficacy.

Effect of a web-based positive psychology intervention on prenatal well-being: A case series study.

BACKGROUND: Detrimental effects of women's negative feelings during pregnancy have been extensively examined and documented, but research on the influence of positive feelings and protective factors on their prenatal mental health is scarce. Evidence from the positive psychology field has shown that practicing some brief positive exercises, called positive psychology interventions, can maximize well-being by increasing positive emotions, engagement, and meaning. AIM: The aim of this study is to examine the effect of a positive psychology web-based intervention on indices of women's prenatal well-being. METHODS: Specifically, a case series design was adopted, and data from six women are presented. Participants were involved in a 5-week online positive psychology intervention that includes a set of positive psychology interventions specifically adapted for pregnant women. Measures of women's mental well-being, depression, pregnancy-related anxiety, life satisfaction, and social support were measured at pre- and post-intervention. Compliance with the intervention and exercise preferences were assessed at post-test. Single-item related well-being measures were assessed weekly. FINDINGS AND DISCUSSION: The findings of this case series study indicate potential effects of the intervention on supporting mental well-being and decreasing depressive symptomatology in these pregnant women. Furthermore, this study provides some suggestions for developing future online-based positive interventions addressed to pregnant women. However, these findings are preliminary, and future studies are needed in order to assess the effects of the intervention in a wider population of pregnant women.
