BCLA CLEAR Presbyopia: Management with contact lenses and spectacles.

This paper seeks to outline the history, market situation, clinical management and product performance related to the correction of presbyopia with both contact lenses and spectacles. The history of the development of various optical forms of presbyopic correction are reviewed, and an overview is presented of the current market status of contact lenses and spectacles. Clinical considerations in the fitting and aftercare of presbyopic contact lens and spectacle lens wearers are presented, with general recommendations for best practice. Current options for contact lens correction of presbyopia include soft simultaneous, rigid translating and rigid simultaneous designs, in addition to monovision. Spectacle options include single vision lenses, bifocal lenses and a range of progressive addition lenses. The comparative performance of both contact lens and spectacle lens options is presented. With a significant proportion of the global population now being presbyopic, this overview is particularly timely and is designed to act as a guide for researchers, industry and eyecare practitioners alike.

Glucocorticoid response to naturalistic interactions between children and dogs.

Although research has shown that pets appear to provide certain types of social support to children, little is known about the physiological bases of these effects, especially in naturalistic contexts. In this study, we investigated the effect of free-form interactions between children (ages 8-10 years) and dogs on salivary cortisol concentrations in both species. We further investigated the role of the child-dog relationship by comparing interactions with the child's pet dog to interactions with an unfamiliar dog or a nonsocial control condition, and modeled associations between survey measures of the human-animal bond and children's physiological responses. In both children and dogs, salivary cortisol decreased from pre- to post-interaction; the effect was strongest for children interacting with an unfamiliar dog (compared to their pet dog) and for the pet dogs (compared to the unfamiliar dog). We found minimal evidence for associations between cortisol output and behaviors coded from video, but children scoring higher on survey measures of the human-animal bond exhibited the greatest reductions in cortisol when interacting with dogs. Self-reported loneliness was not related to cortisol or the human-animal bond, but measures of both loneliness and the human-animal bond were higher among children who participated after the onset of the COVID-19 pandemic, relative to those who participated before the pandemic. This study builds on previous work that investigated potential stress-buffering effects of human-animal interaction during explicit stressors and demonstrates important physiological correlates of naturalistic interactions between children and dogs, similar to those that occur in daily life.

The impact of Demodex blepharitis on patient symptoms and daily life.

SIGNIFICANCE: Patients with Demodex blepharitis have a considerable symptomatic burden that negatively impacts their daily activities and well-being. Despite chronic manifestations of and problems associated with blepharitis that resulted in multiple visits to eye care providers, Demodex blepharitis remained underdiagnosed or misdiagnosed. PURPOSE: This study aimed to evaluate the effect of Demodex blepharitis on patients' daily activities and well-being. METHODS: This prospective, multicenter, observational study recruited 524 patients with Demodex blepharitis from 20 U.S. ophthalmology and optometry practices. Demodex blepharitis was diagnosed based on the presence of the following clinical manifestations in at least one eye: >10 collarettes on the upper lashes, at least mild lid margin erythema of the upper eyelid, and mite density of ≥1.0 mite/lash (upper and lower combined). Patients were asked to complete a questionnaire related to their symptoms, daily activities, and management approaches. RESULTS: The proportion of patients who experienced blepharitis symptoms for ≥2 years was 67.8%, and for ≥4 years, it was 46.5%. The three most bothersome symptoms ranked were "itchy eyes," "dry eyes," and "foreign body sensation." Overall, 77.4% of patients reported that Demodex blepharitis negatively affected their daily life. One-third (32.3%) of patients had visited a doctor for blepharitis at least two times, including 19.6% who visited at least four times. Despite having clinical manifestations of Demodex blepharitis confirmed by an eye care provider, 58.7% had never been diagnosed with blepharitis. Commonly used management approaches were artificial tears, warm compresses, and lid wipes. Among those who discontinued their regimen, 45.9% had discontinued because of either tolerability issues or lack of effectiveness. Among contact lens wearers, 64.3% of the patients either were uncomfortable wearing contact lenses or experienced vision changes "sometimes" or "frequently." CONCLUSION: Demodex blepharitis results in a significant negative impact on daily activities, creating a psychosocial and symptomatic burden on patients.

Ex Vivo Expanded Cord Blood Natural Killer Cells Combined with Rituximab and High-Dose Chemotherapy and Autologous Stem Cell Transplantation for B Cell Non-Hodgkin Lymphoma.

Relapse is the major cause of failure of high-dose chemotherapy (HDC) with autologous stem cell transplantation (ASCT) for B cell non-Hodgkin lymphomas (B-NHL). Improvement strategies include use in combination with effective immunotherapies. We hypothesized that the combination of rituximab/HDC/ASCT with expanded cord blood (CB)-derived natural killer (NK) cells is safe and active in B-NHL. Patients with B-NHL age 15 to 70 years and appropriate ASCT candidates were eligible for the study. The CB units were selected without considering HLA match with the recipient. The CB NK cells were expanded from day -19 to day -5. Treatment included rituximab on days -13 and -7, BEAM (carmustine/etoposide/cytarabine/melphalan) on days -13 to -7, lenalidomide on days -7 to -2, CB NK infusion (108/kg) on day -5, and ASCT (day 0). The primary endpoint was 30-day treatment-related mortality (TRM); secondary endpoints included relapse-free survival (RFS), overall survival (OS), and persistence of CB NK cells. We enrolled 20 patients. CB NK cells were expanded a median of 1552-fold with >98% purity and >96% viability. We saw no adverse events attributable to the CB NK cells and 0% 30-day TRM. At median follow-up of 47 months, the RFS and OS rates were 53% and 74%, respectively. CB NK cells were detectable in blood for 2 weeks, independent of HLA-mismatch status. CD16 expression in donor NK cells was correlated favorably with outcome, and homozygosity for the high-affinity CD16 variant (158 V/V) in CB, but not recipient, NK cells was correlated with better outcomes. Our data indicate that the combination of expanded and highly purified CB-derived NK cells with HDC/ASCT for B-NHL is safe. CD16 expression in donor NK cells, particularly if homozygous for the high-affinity CD16 variant, was correlated with better outcomes.

High-Dose Chemotherapy and Autologous Stem Cell Transplantation for Relapsed or Refractory Primary Mediastinal Large B-Cell Lymphoma.

Primary mediastinal large B-cell lymphoma (PMBCL) is an uncommon, aggressive type of non-Hodgkin lymphoma. Rituximab-containing chemoimmunotherapy with or without radiation therapy (RT) is standard first-line treatment. Relapsed or refractory (R/R) disease has long been treated with salvage chemotherapy followed by high-dose chemotherapy (HDC), with autologous stem cell transplantation (ASCT) in appropriate patients. We retrospectively analyzed all patients with R/R PMBCL treated with HDC/ASCT at our center between January 2000 and August 2022. The 60 study patients received either rituximab-BEAM (n = 37) or rituximab-gemcitabine/busulfan/melphalan (R-GemBuMel) with or without vorinostat (n = 23), followed by ASCT. Forty-six patients received mediastinal RT, either as prior consolidation of frontline therapy or following ASCT. At median follow-up of 6 years (range, .3 to 21 years), the 5-year progression-free survival (PFS) and overall survival (OS) rates of the whole group were 58% and 77%, respectively, for the entire cohort, 51% and 65% for the R-BEAM recipients, and 69% and 82% for R-vorinostat/GemBuMel recipients. Multivariable analyses showed that a negative positron emission tomography scan at ASCT (hazard ratio [HR], .28) and involvement of only 1 organ (HR, .33) were independently associated with improved PFS. In addition, receipt of R-vorinostat/GemBuMel (HR, .23) was an independent favorable predictor of OS. Our data indicate that HDC/ASCT is effective in R/R PMBCL, with improved outcomes in patients receiving R-vorinostat/GemBuMel.

Demodex Blepharitis: A Comprehensive Review of the Disease, Current Management, and Emerging Therapies.

ABSTRACT: Demodex blepharitis is a common disease of the eyelid, affecting approximately 25 million Americans. This article reviews what is known about the mechanisms and impact of Demodex blepharitis, risk factors, signs and symptoms, diagnostic techniques, current management options, and emerging treatments. Demodex mites contribute to blepharitis in several ways: direct mechanical damage, as a vector for bacteria, and by inducing hypersensitivity and inflammation. Risk factors for Demodex blepharitis include increasing age, rosacea, and diabetes. The costs, symptom burden, and psychosocial effects of Demodex blepharitis are considerable. The presence of collarettes is pathognomonic for Demodex blepharitis. Redness, dryness, discomfort, foreign body sensation, lash anomalies, and itching are also hallmarks of the disease. Although a number of oral, topical, eyelid hygiene and device-based options have been used clinically and evaluated in studies for the management of Demodex blepharitis, none have been FDA approved to treat the disease. Recent randomized controlled clinical trials suggest that lotilaner ophthalmic solution, 0.25%, is a topical treatment with the potential to eradicate Demodex mites and eliminate collarettes and eyelid redness for an extended period.

A new look at teacher interactional quality: Profiles of individual teacher-child relationship and classroom teaching quality among Head Start students.

Preschool teachers' relationships with children are a critical component of classroom quality. We draw from a sample of N=2,114 children attending Head Start to examine child-centered profiles of experiences across two dimensions of classroom interaction quality that are often considered separately, individual teacher-child closeness and conflict and classroom-level instructional and emotional support. Findings reveal considerable heterogeneity in Head Start children's experiences, as the profiles differed on individual conflict, and classroom emotional and instructional support. The largest profile was characterized by a positive emotional climate and low instructional support. Higher teacher distress was associated with the highest quality and the highest conflict profiles. The results also revealed early evidence for gender and race and ethnicity-based disadvantages in Head Start classroom experiences.

TFOS Lifestyle: Impact of contact lenses on the ocular surface.

Several lifestyle choices made by contact lens wearers can have adverse consequences on ocular health. These include being non-adherent to contact lens care, sleeping in lenses, ill-advised purchasing options, not seeing an eyecare professional for regular aftercare visits, wearing lenses when feeling unwell, wearing lenses too soon after various forms of ophthalmic surgery, and wearing lenses when engaged in risky behaviors (e.g., when using tobacco, alcohol or recreational drugs). Those with a pre-existing compromised ocular surface may find that contact lens wear exacerbates ocular disease morbidity. Conversely, contact lenses may have various therapeutic benefits. The coronavirus disease-2019 (COVID-19) pandemic impinged upon the lifestyle of contact lens wearers, introducing challenges such as mask-associated dry eye, contact lens discomfort with increased use of digital devices, inadvertent exposure to hand sanitizers, and reduced use of lenses. Wearing contact lenses in challenging environments, such as in the presence of dust and noxious chemicals, or where there is the possibility of ocular trauma (e.g., sport or working with tools) can be problematic, although in some instances lenses can be protective. Contact lenses can be worn for sport, theatre, at high altitude, driving at night, in the military and in space, and special considerations are required when prescribing in such situations to ensure successful outcomes. A systematic review and meta-analysis, incorporated within the review, identified that the influence of lifestyle factors on soft contact lens dropout remains poorly understood, and is an area in need of further research. Overall, this report investigated lifestyle-related choices made by clinicians and contact lens wearers and discovered that when appropriate lifestyle choices are made, contact lens wear can enhance the quality of life of wearers.

Therapeutic contact lenses for the treatment of corneal and ocular surface diseases: Advances in extended and targeted drug delivery.

The eye is one of the most important organs in the human body providing critical information on the environment. Many corneal diseases can lead to vision loss affecting the lives of people around the world. Ophthalmic drug delivery has always been a major challenge in the medical sciences. Since traditional methods are less efficient (∼5%) at delivering drugs to ocular tissues, contact lenses have generated growing interest in ocular drug delivery due to their potential to enhance drug bioavailability in ocular tissues. The main techniques used to achieve sustained release are discussed in this review, including soaking in drug solutions, incorporating drug into multilayered contact lenses, use of vitamin E barriers, molecular imprinting, nanoparticles, micelles and liposomes. The most clinically relevant results on different eye pathologies are presented. In addition, this review summarizes the benefits of contact lenses over eye drops, strategies for incorporating drugs into lenses to achieve sustained release, results of in vitro and in vivo studies, and recent advances in the commercialization of therapeutic contact lenses for allergic conjunctivitis.

Doubt in store: vaccine hesitancy among grocery workers during the COVID-19 pandemic.

The objective of this study was to assess the influence of workplace safety conditions alongside the World Health Organization's model of the "3 Cs", on grocery store workers' vaccine hesitancy concerning COVID-19. Data for this study come from the Arizona Frontline Workers Survey, a longitudin web-based survey of 770 grocery store workers in the state of Arizona (US) collected in July 2020 and January 2021. We utilized ordinary least squares and multinomial logistic regression analyses to assess predictors of hesitancy at our Wave 2. Thirty-nine percent of our sample reported being unlikely to get vaccinated against COVID-19. Two aspects of the "3 Cs" model, confidence and convenience, were correlated with lower levels of vaccine hesitancy while the perceptions of being protected by one's employer increased hesitancy. Our findings underscore the importance of workplace conditions for vaccine hesitancy and the need to include vaccine messaging in employers' safety practices.

Respect Your Elders: Generativity and Life Satisfaction in Caregiving Grandparents.

Erikson's theory of psychosocial development defines generativity as the drive to benefit future generations and leave a legacy. Generativity has been shown to predict life satisfaction, but generative concern and action can be impacted by factors such as perceived respect from younger generations. This study utilized caregiving grandparents aged 40 and older to assess the extent to which perceived respect mediated the relation between generativity and life satisfaction. Perceived respect from a grandchild mediated the relation between generative concern expressed by caregiving grandparents and life satisfaction after controlling for demographic variables that have been shown to influence heterogeneity and overall well-being in caregiving grandparent samples. These findings suggest that the relation between life satisfaction and generativity in grandparents may depend, in part, on perceived respect from grandchildren, intimating that the implications of generativity may be influenced by the perceived appreciation of its recipients.

How Can We Best Measure the Performance of Scleral Lenses? Current Insights.

Scleral lenses (SLs) present several unique advantageous characteristics for patients. As these lenses are mainly fitted in severely diseased eyes, a thorough evaluation of the ocular surface before and after SL fitting and the on-eye SL fitting evaluation are essential and help minimize potential physiological complications. This review will explore the current and emerging techniques and instrumentation to best measure SL performance ensuring optimal lens fitting, visual quality, comfort and physiological responses, highlighting some potential complications and follow-up recommendations. A single physician could perform the great majority of evaluations. Still, the authors consider that the assessment of SL fitting should be a collaborative and multidisciplinary job, involving contact lens practitioners, ophthalmologists and the industry. This publication has reviewed the most up-to-date work and listed the most used techniques; however, the authors encourage the development of more evidence-based recommendations for SL clinical practice.

Essential but Ill-Prepared: How the COVID-19 Pandemic Affects the Mental Health of the Grocery Store Workforce.

OBJECTIVES: Frontline essential workers face elevated risks of exposure to COVID-19 because of the interactive nature of their jobs, which require high levels of interaction with the general public and coworkers. The impact of these elevated risks on the mental health of essential workers, especially outside the health care sector, is not well studied. To address this knowledge gap, we examined correlations between perceptions of workplace risks and mental health distress among grocery store workers in Arizona. METHODS: We collected the first statewide sample of essential workers outside the health care sector focused on mental health and well-being. A total of 3344 grocery store workers in Arizona completed an online survey in July 2020. We used multiple regression models to identify demographic and work-based correlates of mental health distress. RESULTS: Levels of mental health distress among respondents were high: 557 of 3169 (17.6%) reported severe levels and 482 of 3168 (15.2%) reported moderate levels. Perceptions of workplace safety were strongly correlated with significantly reduced levels of mental health distress (ß = -1.44; SE = 0.20) and reduced perceived stress (ß = -0.97; SE = 0.16). Financially disadvantaged workers and employees aged <55 reported high levels of mental health distress. Perceptions of safety and protection in the workplace were significantly correlated with availability of safety trainings, social distancing, and policies governing customer behaviors. CONCLUSIONS: Lacking sufficient workplace protections, grocery store employees in Arizona experienced high levels of mental health distress during the COVID-19 pandemic. Providing clear federal and state policies to employers to guide implementation of workplace protections may help reduce sources of mental health distress.

Classification of Presbyopia by Severity.

There are close to two billion individuals globally living with presbyopia. In spite of its ubiquitous and progressive nature, there is no widely accepted, formal guideline or consensus statement on the classification of presbyopia by degree of severity. A panel of leading eye care professionals representing both optometrists and ophthalmologists convened virtually to discuss and document their combined assessments from the body of literature and clinical practice expertise in this commentary. In light of emerging therapies, classifying presbyopia by mild, moderate, or advanced severity may help provide consistency of diagnosis among eye care providers and may aid in managing patient expectations with different treatment options.

Improved outcomes of high-risk relapsed Hodgkin lymphoma patients after high-dose chemotherapy: a 15-year analysis.

High-dose chemotherapy and autologous stem-cell transplant (HDC/ASCT) is standard treatment for chemosensitive relapsed classical Hodgkin lymphoma, although outcomes of high-risk relapse (HRR) patients remain suboptimal. We retrospectively analyzed all HRR classical Hodgkin lymphoma patients treated with HDC/ASCT at our institution between 01/01/2005 and 12/31/2019. HRR criteria included primary refractory disease/relapse within 1 year, extranodal extension, B symptoms, requiring more than one salvage line, or positron emission tomography (PET)-positive disease at ASCT. All patients met the same ASCT eligibility criteria. We treated 501 patients with BEAM (n=146), busulphan/melphalan (BuMel) (n=38), gemcitabine( Gem)/BuMel (n=189) and vorinostat/Gem/BuMel (n=128). The Gem/BuMel and vorinostat/Gem/BuMel cohorts had more HRR criteria and more patients with PET-positive disease at ASCT. Treatment with brentuximab vedotin (BV) or anti-PD1 prior to ASCT, PET-negative disease at ASCT, and maintenance BV increased over time. BEAM and BuMel predominated in earlier years (2005-2007), GemBuMel and BEAM in middle years (2008-2015), and vorinostat/GemBuMel and BEAM in later years (2016-2019). The median follow-up is 50 months (range, 6-186). Outcomes improved over time, with 2-year progressionfree survival (PFS)/overall survival (OS) rates of 58%/82% (2005-2007), 59%/83% (2008-2011), 71%/94% (2012-2015) and 86%/99% (2016- 2019) (P<0.0001). Five-year PFS/OS rates were 72%/87% after vorinostat/ GemBuMel, 55%/75% after GemBuMel, 45%/61% after BEAM, and 39%/57% after BuMel (PFS: P=0.0003; OS: P<0.0001). These differences persisted within the PET-negative and PET-positive subgroups. Prior BV and vorinostat/GemBuMel were independent predictors of more favorable outcome, whereas primary refractory disease, ≥2 salvage lines, bulky relapse, B symptoms and PET-positivity at ASCT correlated independently with unfavorable outcomes. In conclusion, post-HDC/ASCT outcomes of patients with HRR classic Hodgkin lymphoma have improved over the last 15 years. Pre-ASCT BV treatment and optimized synergistic HDC (vorinostat/GemBuMel) were associated with this improvement.

Coping profiles in the context of global environmental threats: a person-centered approach.

Profound environmental changes will affect vast human populations, if not pose an existential threat to humanity, raising the question how individuals will adapt psychologically to address these changes and how they manage stress and anxiety in the face of chronic threats such as climate change. We propose that ecological coping (efforts to manage adaptational demands of a degrading environment) is an important construct. Our purpose is to use a person-centered approach to identify profiles of ecological coping and to determine how these profiles differ on mental health outcomes and pro-environmental behaviors in an online survey (N = 334 U.S. adults). Using Latent Profile Analysis (LPA), we also investigate whether these profiles are explained based on general (demographics) or environment-specific (e.g., eco-stressors) factors. Results showed: (1) The identification of two profiles: Adaptive Approach Coping (P1; 69.46%) and Maladaptive Avoidance Coping (P2; 30.54%); (2) Environment-related factors (vs. health) are associated with the profiles; (3) All 6 environment-specific characteristics predicted profile membership. Future research and policy can use these profiles to develop interventions to increase pro-environmental engagement to address climate change.

Presbyopia Treatments by Mechanism of Action: A New Classification System Based on a Review of the Literature.

Presbyopia, a loss of accommodative ability associated with aging, is a significant cause of vision impairment globally. At the clinical level, it is a frustrating and difficult issue that negatively impacts patients' quality of life. Less appreciated is the fact that loss of accommodative ability and its current treatments methods may present safety concerns, for example, increasing the risk of falls. Therefore, a more complete understanding of treatment options with respect to how they relate to the natural ability of the eye is needed to improve decision making and to aid clinicians in individualizing treatment options. This article reviews the options for expanding functional through focus-a term coined to describe the ability of the eye to see at all distances with minimal latency-by how they vary the refractive power over time, across the visual field, between eyes, or across a range of distances.

Third-Party BK Virus-Specific Cytotoxic T Lymphocyte Therapy for Hemorrhagic Cystitis Following Allotransplantation.

PURPOSE: BK virus-associated hemorrhagic cystitis (BKV-HC) is a common complication of allogenic hematopoietic stem cell transplantation (AHSCT), particularly in recipients of alternative donor transplants, which are being performed in increasing numbers. BKV-HC typically results in painful hematuria, urinary obstruction, and renal dysfunction, without a definitive therapeutic option. METHODS: We performed a clinical trial (ClinicalTrials.gov identifier: NCT02479698) to assess the feasibility, safety, and efficacy of administering most closely HLA-matched third-party BKV-specific cytotoxic T lymphocytes (CTLs), generated from 26 healthy donors and banked for off-the-shelf use. The cells were infused into 59 patients who developed BKV-HC following AHSCT. Comprehensive clinical assessments and correlative studies were performed. RESULTS: Response to BKV-CTL infusion was rapid; the day 14 overall response rate was 67.7% (40 of 59 evaluable patients), which increased to 81.6% among evaluable patients at day 45 (40 of 49 evaluable patients). No patient lost a previously achieved response. There were no cases of de novo grade 3 or 4 graft-versus-host disease, graft failure, or infusion-related toxicities. BKV-CTLs were identified in patient blood samples up to 3 months postinfusion and their in vivo expansion predicted for clinical response. A matched-pair analysis revealed that, compared with standard of care, after accounting for prognostic covariate effects, treatment with BKV-CTLs resulted in higher probabilities of response at all follow-up timepoints as well as significantly lower transfusion requirement. CONCLUSION: Off-the-shelf BKV-CTLs are a safe and effective therapy for the management of patients with BKV-HC after AHSCT.
