Vegetables and fruit provide a significant part of human nutrition, as they are important sources of nutrients, dietary fibre, and phytochemicals. However, it is uncertain whether the risk of certain chronic diseases can be reduced by increased consumption of vegetables or fruit by the general public, and what strength of evidence has to be allocated to such an association. Therefore, a comprehensive analysis of the studies available in the literature and the respective study results has been performed and evaluated regarding obesity, type 2 diabetes mellitus, hypertension, coronary heart disease (CHD), stroke, cancer, chronic inflammatory bowel disease (IBD), rheumatoid arthritis (RA), chronic obstructive pulmonary disease (COPD), asthma, osteoporosis, eye diseases, and dementia. For judgement, the strength of evidence for a risk association, the level of evidence, and the number of studies were considered, the quality of the studies and their estimated relevance based on study design and size. For hypertension, CHD, and stroke, there is convincing evidence that increasing the consumption of vegetables and fruit reduces the risk of disease. There is probable evidence that the risk of cancer in general is inversely associated with the consumption of vegetables and fruit. In addition, there is possible evidence that an increased consumption of vegetables and fruit may prevent body weight gain. As overweight is the most important risk factor for type 2 diabetes mellitus, an increased consumption of vegetables and fruit therefore might indirectly reduces the incidence of type 2 diabetes mellitus. Independent of overweight, there is probable evidence that there is no influence of increased consumption on the risk of type 2 diabetes mellitus. There is possible evidence that increasing the consumption of vegetables and fruit lowers the risk of certain eye diseases, dementia and the risk of osteoporosis. Likewise, current data on asthma, COPD, and RA indicate that an increase in vegetable and fruit consumption may contribute to the prevention of these diseases. For IBD, glaucoma, and diabetic retinopathy, there was insufficient evidence regarding an association with the consumption of vegetables and fruit. This critical review on the associations between the intake of vegetables and fruit and the risk of several chronic diseases shows that a high daily intake of these foods promotes health. Therefore, from a scientific point of view, national campaigns to increase vegetable and fruit consumption are justified. The promotion of vegetable and fruit consumption by nutrition and health policies is a preferable strategy to decrease the burden of several chronic diseases in Western societies.

Critical review: vegetables and fruit in the prevention of chronic diseases

Importance Adult survivors of childhood cancer are known to be at risk for treatment-related adverse health outcomes. A large population of survivors has not been evaluated using a comprehensive systematic clinical assessment to determine the prevalence of chronic health conditions. Objective To determine the prevalence of adverse health outcomes and the proportion associated with treatment-related exposures in a large cohort of adult survivors of childhood cancer. Design, Setting, and Participants Presence of health outcomes was ascertained using systematic exposure–based medical assessments among 1713 adult (median age, 32 [range, 18-60] years) survivors of childhood cancer (median time from diagnosis, 25 [range, 10-47] years) enrolled in the St Jude Lifetime Cohort Study since October 1, 2007, and undergoing follow-up through October 31, 2012. Main Outcomes and Measures Age-specific cumulative prevalence of adverse outcomes by organ system. Results Using clinical criteria, the crude prevalence of adverse health outcomes was highest for pulmonary (abnormal pulmonary function, 65.2% [95% CI, 60.4%-69.8%]), auditory (hearing loss, 62.1% [95% CI, 55.8%-68.2%]), endocrine or reproductive (any endocrine condition, such as hypothalamic-pituitary axis disorders and male germ cell dysfunction, 62.0% [95% CI, 59.5%-64.6%]), cardiac (any cardiac condition, such as heart valve disorders, 56.4% [95% CI, 53.5%-59.2%]), and neurocognitive (neurocognitive impairment, 48.0% [95% CI, 44.9%-51.0%]) function, whereas abnormalities involving hepatic (liver dysfunction, 13.0% [95% CI, 10.8%-15.3%]), skeletal (osteoporosis, 9.6% [95% CI, 8.0%-11.5%]), renal (kidney dysfunction, 5.0% [95% CI, 4.0%-6.3%]), and hematopoietic (abnormal blood cell counts, 3.0% [95% CI, 2.1%-3.9%]) function were less common. Among survivors at risk for adverse outcomes following specific cancer treatment modalities, the estimated cumulative prevalence at age 50 years was 21.6% (95% CI, 19.3%-23.9%) for cardiomyopathy, 83.5% (95% CI, 80.2%-86.8%) for heart valve disorder, 81.3% (95% CI, 77.6%-85.0%) for pulmonary dysfunction, 76.8% (95% CI, 73.6%-80.0%) for pituitary dysfunction, 86.5% (95% CI, 82.3%-90.7%) for hearing loss, 31.9% (95% CI, 28.0%-35.8%) for primary ovarian failure, 31.1% (95% CI, 27.3%-34.9%) for Leydig cell failure, and 40.9% (95% CI, 32.0%-49.8%) for breast cancer. At age 45 years, the estimated cumulative prevalence of any chronic health condition was 95.5% (95% CI, 94.8%-98.6%) and 80.5% (95% CI, 73.0%-86.6%) for a serious/disabling or life-threatening chronic condition. Conclusions and Relevance Among adult survivors of childhood cancer, the prevalence of adverse health outcomes was high, and a systematic risk-based medical assessment identified a substantial number of previously undiagnosed problems that are more prevalent in an older population. These findings underscore the importance of ongoing health monitoring for adults who survive childhood cancer.

The Lancet Global Health Commission on Global Eye Health: vision beyond 2020.

Cataract is a visible opacity in the lens substance, which, when located on the visual axis, leads to visual loss. Age-related cataract is a cause of blindness on a global scale involving genetic and environmental influences. With ageing, lens proteins undergo non-enzymatic, post-translational modification and the accumulation of fluorescent chromophores, increasing susceptibility to oxidation and cross-linking and increased light-scatter. Because the human lens grows throughout life, the lens core is exposed for a longer period to such influences and the risk of oxidative damage increases in the fourth decade when a barrier to the transport of glutathione forms around the lens nucleus. Consequently, as the lens ages, its transparency falls and the nucleus becomes more rigid, resisting the change in shape necessary for accommodation. This is the basis of presbyopia. In some individuals, the steady accumulation of chromophores and complex, insoluble crystallin aggregates in the lens nucleus leads to the formation of a brown nuclear cataract. The process is homogeneous and the affected lens fibres retain their gross morphology. Cortical opacities are due to changes in membrane permeability and enzyme function and shear-stress damage to lens fibres with continued accommodative effort. Unlike nuclear cataract, progression is intermittent, stepwise and non-uniform.

The ageing lens and cataract: a model of normal and pathological ageing

Background/aim: A third of elderly people fall each year Poor vision is associated with increased risk of falls The authors aimed to determine if first eye cataract surgery reduces the risk of falling, and to measure associated health gain

Methods: 306 women aged over 70, with cataract, were randomised to expedited (approximately 4 weeks) or routine (12 months wait) surgery Falls were ascertained by diary, with follow up every 3 months Health status was measured after 6 months

Results: Visual function improved in the operated group (corrected binocular acuity improved by 025 logMAR units; 8% had acuity worse than 6/12 compared with 37% of controls) Over 12 months of follow up, 76 (49%) operated participants fell at least once, and 28 (18%) fell more than once 69 (45%) unoperated participants fell at least once, 38 (25%) fell more than once Rate of falling was reduced by 34% in the operated group (rate ratio 066, 95% confidence interval 045 to 096, p = 003) Activity, anxiety, depression, confidence, visual disability, and handicap all improved in the operated group compared with the control group Four participants in the operated group had fractures (3%), compared with 12 (8%) in the control group (p = 004)

Conclusion: First eye cataract surgery reduces the rate of falling, and risk of fractures and improves visual function and general health status

BostonSight, Needham, MA, USA Purpose: To evaluate the impact of prosthetic replacement of the ocular surface ecosystem (BostonSight PROSE) treatment on symptom outcomes based on the Ocular Surface Disease Index (OSDI). Patients and Methods: This was a single-center, retrospective analysis of consecutive patients who initiated PROSE treatment between September 2017 and December 2019 by the same clinician. The primary outcome measure was to compare OSDI survey scores at baseline prior to PROSE treatment and at follow-up, after PROSE treatment. Indication for treatment, sex, age, device diameter, average wear time, preexisting mental illness, duration of PROSE wear, and status of PROSE wear at follow-up were also studied. Results: A total of 134 patients underwent PROSE treatment and completed a baseline OSDI survey during the study period. Forty-three patients completed a follow-up OSDI survey and were included in the study analysis. The most common treatment indications were keratoconjunctivitis sicca (n=27) and corneal ectasia (n=16). Baseline average OSDI score was 56.9±23.7 for the 43 subjects who completed a subsequent OSDI survey. The last documented average follow-up OSDI for those 43 subjects was 23.8±15.6, median (IQR) of 22.9 (10.4 to 32.3), and a statistically significant 54.7±27.6% average improvement from baseline (p<0.01). All patients, except for two, showed improvement in OSDI score. Statistically significant improvement occurred regardless of underlying diagnosis with no statistically significant difference based on age, sex, mental illness, or device diameter and no statistical correlation with average wear time, or duration of PROSE wear. Conclusion: PROSE treatment improves visual function and symptom relief as demonstrated by the OSDI survey. Sex, age, preexisting mental illness, device diameter, average wear time, and duration of wear had no statistically significant impact on OSDI outcomes.

OSDI Outcomes Based on Patient Demographic and Wear Patterns in Prosthetic Replacement of the Ocular Surface Ecosystem

ABSTRACT
A 52-year-old white man with keratoconus and severe atopic keratoconjunctivitis underwent penetrating keratoplasty (PK) for visual rehabilitation in the left eye. Post-PK complications included a persistent epithelial defect. Therapeutic scleral lens wear was initiated 2 weeks post-PK. Customizations were incorporated into the lens design to prevent suction and corneal hypoxia during lens wear. Post-PK herpes epithelial keratitis developed shortly thereafter, causing recurrence of a nonhealing epithelial defect. The patient was treated with oral antiviral therapy, discontinuation of dupilumab, and daily waking-hour scleral lens wear, which was used as an antibiotic drug delivery device. The cornea fully epithelialized, and best-corrected visual acuity improved to 20/40-2. The patient continued with daily waking-hour scleral lens wear and was without recurrence of persistent epithelial defect or herpes keratitis at 18 months. No scleral lens-related complications were observed despite the unconventional early intervention with a therapeutic scleral lens.

Case report: Utilization of neutral density filters for densitometry analysis of dense corneal opacities

Purpose To understand the degree and explore the possible causes of ocular graft-versus-host disease (oGVHD) underdiagnosis in patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients and Methods A 15-question survey was emailed to 6032 subscribers to the Blood and Marrow Transplant Information Network. A total of 371 respondents confirmed the history of allo-HSCT, of which 335 were symptomatic. Their self-reported symptoms, onset, treatments tried, degree of symptom control and established diagnoses of systemic chronic graft-versus-host disease (cGVHD) and oGVHD were analyzed. Results Among the 335 symptomatic survey respondents, 306 reported their ocular symptom onset was after allo-HSCT, with only 170 [55.6% (170/306)] ever receiving a diagnosis of oGVHD; 23 reported worsening pre-existing ocular symptoms after allo-HSCT, with only 5 [21.7% (5/23)] ever receiving a diagnosis of oGVHD; 6 reported stable symptoms before and after allo-HSCT, with 1 ever receiving a diagnosis of oGVHD. Of the 176 respondents carrying the diagnosis of oGVHD, 167 [94.9% (167/176)] also had the diagnosis of cGVHD. Logistic regression analysis showed that the diagnosis of oGVHD was highly correlated with the number of symptoms and treatments one reported. Furthermore, 35% of the respondents with new onset ocular symptoms reported onset within the first 6 months after allo-HSCT (previously reported), as well as 39% of the respondents with worsened existing symptoms. Conclusion oGVHD underdiagnosis is likely associated with the previous diagnostic criteria, in which cGVHD of another organ system was required. The correct notion that oGVHD commonly causes severe dry eye disease has likely led to its underdiagnosis in patients with fewer number of symptoms and/or who tried fewer treatments.
