ABSTRACT

PURPOSE: To assess vision-related quality of life (VrQoL) in cases with visual loss after ocular trauma (OT) or non-traumatic ocular disease (NTOD) using the National Eye Institute’s 25-Item Visual Function Questionnaire 25 (VFQ-25) and its association with visual disability % (VD%) based on the Rights of Persons with Disabilities (RPwD) Act, 2016.

METHODS: This was a prospective observational study conducted among cases with ocular morbidity in either or both eyes with a visual acuity of ≤6/24. VFQ-25 questionnaire was administered to measure QoL scores. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS) version 23. P < 0.05 was taken as significant.

RESULTS: Eighty-eight respondents completed the questionnaire. Mean age of participants was 40.272 ± 9.35 years (range: 23-55 years). Forty-three (48.9%) and 45 (51.1%) participants had OT and NTOD, respectively. The most common cause was traumatic optic neuropathy (21.6%) followed by corneal causes (19.4%). Low visual QoL scores were reported in all the cases (57.52 ± 16.08). Between OT and NTOD, a significant difference in terms of age (P = 0.001) and general vision (P = 0.03) was seen. Lowest scores were for driving. Based on VD%, 77 cases had ≤40 and the rest had >40% VD with a significant difference in overall mean scores (P = 0.03), specifically in domains of general vision (P = 0.00), near activities (P = 0.00), and driving (P = 0.007). QoL was decreased in each subscale of ≤40%VD group, who faced the same predicament everywhere as by the cases with more disability.

CONCLUSION: Ocular morbidity is associated with low QoL, predominantly in domains like general vision, near activities and driving. The RPwD Act leaves out a huge population with VD without any government benefits. One might need to consider other vision-related factors also to provide them with social, psychological, and employment benefits.

ABSTRACT

PURPOSE: This study was conducted to assess the outcomes of bleb needling for the treatment of failure of filtration surgeries in primary glaucoma with a follow-up of six months.

METHODS: This prospective interventional study included patients with primary glaucoma who underwent trabeculectomy or combined glaucoma and cataract surgery with failed or failing bleb after six weeks of surgery and less than two years. A comprehensive examination including best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, gonioscopy, slit-lamp examination, and bleb morphology grading was done. Selected patients underwent a subconjunctival bleb needling with mitomycin C (MMC) (dose 0.2 mg/ml). Postoperatively, patients were followed up on the first, third, and sixth months and were assessed with respect to IOP, need for antiglaucoma medication (AGM), and complications.

RESULTS: Sixty eyes of 59 patients were included. Preoperatively, 33.3% of patients were on one AGM, whereas postoperatively at the third month 51.7% and at the sixth month 50% of patients were on no AGM. There was a statistically significant decrease in IOP (P < 0.001) from preoperative (mean: 23.8 ± 7.86 mmHg) to postoperative first month (mean: 19.8 ± 9.08 mmHg), third month (mean: 17.4 ± 5.4 mmHg) and sixth month (mean 16.6 ± 4.39). According to the defined criteria in the current study, we achieved 22 (37.9%) successes, 31 qualified successes (53.4%), and 5 (8.6%) failures. Univariate regression analysis showed a higher failure rate among younger age groups. Gender, laterality, and intraoperative complications were not significant statistically.

CONCLUSION: Bleb needling is a safe and effective procedure for the treatment of failed filtration surgeries.

ABSTRACT

PURPOSE: To determine if high myopia and glaucoma can be differentiated based on the measurement of superficial vascular density in the peripapillary and macular areas by using Optical Coherence Tomography Angiography (OCTA).

METHODS: This prospective, observational, cross-sectional, comparative study was conducted on patients between 40 and 60 years of age diagnosed as primary open-angle glaucoma (POAG) or high myopia and compared with age-matched controls. The main outcome measures were the difference in SVD% in peripapillary and macular areas in POAG and high myopic eyes. Detailed ophthalmic examination and OCTA of the disc and peripapillary area and macula were performed. The SVD in each zone was calculated using ImageJ software and their difference were analyzed.

RESULTS: In total, 128 eyes of 70 patients were enrolled. Peripapillary SVD% in controls was 45.07 ± 3.44, 40.36 ± 8.27 in high myopia, and 31.80 ± 9.008 in POAG. The mean difference in peripapillary SVD% of POAG to control was – 13.479, of POAG to high myopia was -8.777 (both P < 0.001), and of high myopia to controls was -4.701 (P = 0.012). Macular SVD% in controls was 27.30 ± 3.438, 22.33 ± 6.011 in high myopia, and 21.21 ± 5.598 in POAG. The mean difference in macular SVD% of POAG to controls was -6.088, of high myopia to controls was -4.965 (both P < 0.001), and of POAG to high myopia was -1.122 (P = 0.984; not statistically significant).

CONCLUSION: OCTA is a useful diagnostic tool in distinguishing glaucomatous and myopic eyes. The measurement of peripapillary SVD has a greater discriminatory ability than that of the macular area.

ABSTRACT

BACKGROUND: Bilirubin may prevent lipid peroxidation and have important antiatherosclerotic effects. We determined associations of serum bilirubin and lipid with peripheral atherosclerosis.

METHODS: We included 4290 participants (35% men; median age, 60 years) from the southeast China who underwent B-mode ultrasound examination. Increased intima-media thickness or a focal structure encroaching into the arterial lumen by at least 0.5 mm or >50% of the surrounding intima-media thickness value was regarded as having atherosclerosis. Fasting serum bilirubin and lipid levels were measured. Cholesterol/(HDL [high-density lipoprotein] cholesterol+bilirubin), and LDL (low-density lipoprotein cholesterol)/(HDL+bilirubin) ratios were calculated. Unconditional and multinomial logistic regression models were used to examine associations of bilirubin or lipid with prevalence of peripheral atherosclerosis. Mediation analyses were performed to assess the effect of bilirubin on atherosclerosis risk mediated via lipid.

RESULTS: Compared with participants with the lowest levels of bilirubin, those with the highest tertile were less likely to have carotid or femoral atherosclerosis (odds ratios were 0.55-0.74). The highest levels of bilirubin significantly reduced the odds of concurrent carotid and femoral atherosclerosis by 35% to 45%. Participants with the highest levels of cholesterol, LDL, cholesterol/(HDL+bilirubin), and LDL/(HDL+bilirubin) ratios had 2.8- to 3.7-fold increased odds of concurrent carotid and femoral atherosclerosis. LDL accounted for 25.65% of the total bilirubin-atherosclerosis association. LDL and cholesterol mediated the associations between direct bilirubin and atherosclerosis (proportion: 20.40%, 9.67%, respectively).

CONCLUSIONS: Increased serum bilirubin levels are inversely associated with the prevalence of carotid or femoral atherosclerosis. LDL and cholesterol may mediate these associations.

ABSTRACT

BACKGROUND: There are limited data regarding the prevalence of distinct clinical, neuroimaging and genetic markers among patients diagnosed with cerebral amyloid angiopathy-related inflammation (CAA-ri). We sought to determine the prevalence of clinical, radiological, genetic and cerebrospinal fluid biomarker findings in patients with CAA-ri.

METHODS: A systematic review and meta-analysis of published studies including patients with CAA-ri was conducted to determine the prevalence of clinical, neuroimaging, genetic and cerebrospinal fluid biomarker findings. Subgroup analyses were performed based on (1) prospective or retrospective study design and (2) CAA-ri diagnosis with or without available biopsy. We pooled the prevalence rates using random-effects models and assessed the heterogeneity using Cochran-Q and I²-statistics.

RESULTS: We identified 4 prospective and 17 retrospective cohort studies comprising 378 patients with CAA-ri (mean age, 71.5 years; women, 52%). The pooled prevalence rates were as follows: cognitive decline at presentation 70% ([95% CI, 54%-84%]; I²=82%), focal neurological deficits 55% ([95% CI, 40%-70%]; I²=82%), encephalopathy 54% ([95% CI, 39%-68%]; I²=43%), seizures 37% ([95% CI, 27%-49%]; I²=65%), headache 31% ([95% CI, 22%-42%]; I²=58%), T2/fluid-attenuated inversion recovery-hyperintense white matter lesions 98% ([95% CI, 93%-100%]; I²=44%), lobar cerebral microbleeds 96% ([95% CI, 92%-99%]; I²=25%), gadolinium enhancing lesions 54% ([95% CI, 42%-66%]; I²=62%), cortical superficial siderosis 51% ([95% CI, 34%-68%]; I²=77%) and lobar macrohemorrhage 40% ([95% CI, 11%-73%]; I²=88%). The prevalence rate of the ApoE (Apolipoprotein E) ε4/ε4 genotype was 34% ([95% CI, 17%-53%]; I²=76%). Subgroup analyses demonstrated no differences in these prevalence rates based on study design and diagnostic strategy.

CONCLUSIONS: Cognitive decline was the most common clinical feature. Hyperintense T2/fluid-attenuated inversion recovery white matter lesions and lobar cerebral microbleeds were by far the most prevalent neuroimaging findings. Thirty-four percent of patients with CAA-ri have homozygous ApoE ε4/ε4 genotype and scarce data exist regarding the cerebrospinal fluid biomarkers and its significance in these patients.

ABSTRACT

BACKGROUND: While clinical guidelines recommend direct-acting oral anticoagulants (DOAC) over warfarin to treat isolated nonvalvular atrial fibrillation, guidelines are silent regarding nonvalvular atrial fibrillation treatment among individuals with cancer, reflecting the paucity of evidence in this setting. We quantified relative risk of ischemic stroke or systemic embolism and major bleeding (primary outcomes), and all-cause and cardiovascular death (secondary outcomes) among older individuals with cancer and nonvalvular atrial fibrillation comparing DOACs and warfarin.

METHODS: This retrospective cohort study used Surveillance, Epidemiology, and End Results cancer registry and linked US Medicare data from 2010 through 2016, and included individuals diagnosed with cancer and nonvalvular atrial fibrillation who newly initiated DOAC or warfarin. We used inverse probability of treatment weighting to control confounding. We used competing risk regression for primary outcomes and cardiovascular death, and Cox proportional hazard regression for all-cause death.

RESULTS: Among 7675 individuals included in the cohort, 4244 (55.3%) received DOACs and 3431 (44.7%) warfarin. In the inverse probability of treatment weighting analysis, there was no statistically significant difference among DOAC and warfarin users in the risk of ischemic stroke or systemic embolism (1.24 versus 1.19 events per 100 person-years, adjusted hazard ratio 1.41 [95% CI, 0.92-2.14]), major bleeding (3.08 versus 4.49 events per 100 person-years, adjusted hazard ratio 0.90 [95% CI, 0.70-1.17]), and cardiovascular death (1.88 versus 3.14 per 100 person-years, adjusted hazard ratio 0.82 [95% CI, 0.59-0.1.13]). DOAC users had significantly lower risk of all-cause death (7.09 versus 13.3 per 100 person-years, adjusted hazard ratio 0.81 [95% CI, 0.69-0.94]) compared to warfarin users.

CONCLUSIONS: Older adults with cancer and atrial fibrillation exposed to DOACs had similar risks of stroke and systemic embolism and major bleeding as those exposed to warfarin. Relative to warfarin, DOAC use was associated with a similar risk of cardiovascular death and a lower risk of all-cause death.

ABSTRACT

Alzheimer’s disease (AD) is a neurodegenerative disorder that has a significant association with age. Despite its increasing incidence in the population, the etiology of the disease remains poorly understood, and there are currently no effective treatments readily available. The main genes that are associated with AD are the amyloid precursor protein, presenilin‑1 and presenilin‑2, as well as the apolipoprotein E gene. In addition to genetic factors, a wide range of environmental and lifestyle factors are equally characterized as risk factors for the development of AD, while non‑coding RNAs (ncRNAs) and other epigenetic mechanisms play a key role in their detrimental effects. Multiple types of ncRNAs, such as microRNAs, circular RNAs, Piwi‑interacting RNAs and long non‑coding RNAs are being increasingly implicated in AD. Alterations in ncRNAs can be detected in cerebrospinal fluid, as well in as the brain, highlighting these as promising biomarkers for the detection and treatment of AD. Developments in high‑throughput technologies have led to the so‑called ‘omics’ era, which involves the collection of big data and information at both molecular and protein levels, while combining the development of novel computational and statistical tools capable of analyzing and filtering such data. The present review discusses the role of ncRNAs and their use as biomarkers for AD, and summarizes the findings from the application of omics technologies in AD.

ABSTRACT

Background Palliative care is a key approach in improving the quality of life of patients and their families facing the end-of-life care process. It is widely regarded as a public-health concern, especially considering the rapidly increasing end-of-life care needs worldwide. Its provision has been highly challenged by the COVID-19 pandemic emergency. Objective This study aims to analyse whether and to what extent the provision of Palliative Care to non-COVID patients provided by a hospital-based unit has changed during the COVID-19 pandemic. Material and methods A retrospective observational study was performed. All non-COVID patients admitted from October 1, 2019 to September 30, 2020 and evaluated by the hospital-based Palliative Care team were considered. Three time periods were considered: pre-lockdown, lockdown and post-lockdown. A trend analysis and multiple linear and logistic regressions to study and quantify the statistical significance of the associations were performed. Results A statistically significant positive linear trend of the number of hospitalized patients in need of Palliative Care was found over the study period. Compared to pre-lockdown, the rest of the study period presented more female and elderly patients, the length of stay and the number of patients discharged to a Hospice setting were significantly reduced. The waiting time did not change in lockdown but decreased in post-lockdown and the mortality rate was not significantly different. Also, the average number of Palliative Care consultations per patient significantly increased in the lockdown and post-lockdown. Discussion First, the significant admissions drop between the start of the pandemic and the following study period is in line with recent literature. The consequent rebound registered may be attributed to the high pressure from outside requiring admission and care. Second, the significantly older age of patients found during the lockdown than before the lockdown could be attributed to a “selection effect” of young patients, more able to delay hospitalization than the elderly, also in line with recent literature. Third, the shorter waiting time for Palliative Care activation the post-lockdown compared to the pre-lockdown period could be due to both increased hospital efficiency and to the greater pressure to discharge patients during the post-lockdown period. Also, the significant reduction in the lockdown and post-lockdown of the length of stay after Palliative Care activation could be explained considering both the greater receptivity of healthcare services outside the hospital, such as Hospices, and the greater pressure on hospital wards to discharge. Fourth, the unchanged in-hospital mortality rate remained over the entire period could be an indication of the high quality of care provided by this hospital setting to fragile patients, which is to be noted especially considering the average mortality rate registered during pandemic context in healthcare facilities. Conclusions The study aimed to quantify the impact of the COVID-19 on the provision of Palliative Care by a hospital-based team. We believe it might represent an innovative contribution and we hope similar research will be produced in order build the evidence for future challenges in this field.

ABSTRACT

OBJECTIVE: To evaluate the effect of pre-biopsy povidone-iodine rectal cleansing on post-biopsy hospitalization rates due to prostate biopsy-related infectious complications.

MATERIAL AND METHODS: In this retrospective study, we reviewed 552 patients who underwent ultrasonography-guided transrectal prostate biopsy between 2014 and 2022. Group 1, 361 patients (January 2014-October 2020) were not applied povidone-iodine rectal cleansing, and group 2, 191 patients (November 2020-January 2022) were applied povidone-iodine rectal cleansing since we changed our biopsy protocol. All patients were given the same antibiotic prophylaxis, ciprofloxacin 500 mg, and ornidazole 500 mg twice daily starting 24 h before the biopsy and lasting a total of 5 days. Sodium phosphate enema was applied to all patients in the biopsy morning. The outcome was the hospitalization rates of patients because of infectious complications a month after the biopsy.

RESULTS: No patients were hospitalized in the povidone-iodine rectal cleansing group because of biopsy related complications. The hospitalization rate of group 1 was 3% and there was a statistical difference between groups.

CONCLUSION: The povidone-iodine solution is cheap, safe and easy to apply. The povidone-iodine rectal cleansing method seems to decrease infectious complications related to prostate biopsy procedure, but we need a randomized controlled trial to confirm our study.

TRIAL REGISTRATION: We got permission for this retrospective study from the Karabuk university ethics council with the number 2021/649 on 1 October 2021.

ABSTRACT

Research in sports biomechanics often relies on the use of ordinary least squares (OLS) regression. However, since sports biomechanics research is often characterised by high-dimensional data sets with many predictor variables and few observations, use of OLS regression can sometimes be problematic from a statistical perspective. Statistical learning methods may provide alternate ways to deal with high-dimensional data sets and partially address these problems. For example, regularisation adds penalties to the cost function of OLS regression models, which shrinks large regression coefficients and decreases the model’s sensitivity to noise in the data. Regularised regression models also protect against overfitting, improve generalisability, and can be used for variable selection. A short review of biomechanics research studies illustrates how these models provided ways to reduce the number of variables within a model and select only the primary predictors of performance, which helped with the interpretation of results and identified distinct combinations of key predictors of performance. In addition, we illustrate how these models are applied to two sports biomechanics datasets. Given the advantages, sports biomechanists may want to consider the use of regularised regression models in their research design and statistical analyses. Careful consideration should be given, however, to the construction, validation, and interpretation of these models considering their underpinning assumptions and limitations.
