RESUMO
PRCIS: There is evidence that cataract surgery can reduce intraocular pressure in patients with primary open angle, normal tension, or exfoliative glaucoma. The complete effect of phacoemulsification is masked by topical intraocular pressure-lowering medications. PURPOSE: To assess the impact of phacoemulsification and intraocular lens implantation on intraocular pressure (IOP) level in individuals with primary open angle glaucoma (POAG), exfoliative glaucoma (XFG), exfoliation syndrome (XFS), normal tension glaucoma (NTG), ocular hypertension (OH), or healthy controls 12 months after the surgery. METHODS: In July 2023, a comprehensive literature review was conducted across six databases. The analysis focused on the phacoemulsification arms of randomized controlled trials (RCTs). The primary outcome of interest was the mean IOP change observed 12 months after phacoemulsification. RESULTS: This meta-analysis included 9 arms from 9 RCTs, comprising a total of 502 participants. Overall, the average IOP was reduced by 3.77 mm Hg (95% CI: -5.55 to -1.99, I2 =67.9%) 12 months after surgery. The subgroup analysis, focused on whether a washout period was used before measuring IOP, revealed that studies with a washout period exhibited a more pronounced IOP reduction of 5.25 mm Hg (95% CI: -7.35 to -3.15, I2 =0%), while studies without a washout period exhibited a reduction of 3.13 mm Hg (95% CI: -5.46 to -0.81, I2 =75.8%). The sensitivity analysis for the latter group, excluding an outlier study, showed a reduction of 1.81 mm Hg (95% CI: -2.95 to -0.67, I2 =0%). CONCLUSIONS: The findings of this systematic review and meta-analysis indicate that cataract surgery meaningfully lowers IOP in POAG, XFG/XFS, or OH 12 months after surgery. However, the use of topical medications masks the precise impact of phacoemulsification upon postoperative IOP. Further research using appropriate washout periods is warranted.

PURPOSE: The aim of this study was to investigate the contrast mechanisms of Contrast-enhanced steady-state free-precession (CE-SSFP) through the utilization of Bloch simulations in an experimental porcine model and in patients with acute myocardial infarction. METHODS: Six pigs and ten patients with myocardial infarction underwent CMR and tissue characterization at 1.5 T whereas a Bloch simulation framework was utilized to simulate the CE-SSFP signal formation and compare it against the actual CE-SSFP signal acquired from the experimental porcine model and the patient population. The relaxation times of remote, salvaged, and infarcted myocardium were calculated after the injection of gadolinium, at the time of CE-SSFP acquisition. Simulations were performed using the same CE-SSFP pulse sequence as used on the scanner on a set of spins with the calculated relaxation times from the CMR scans. RESULTS: The normalized signal intensities of salvaged and infarcted myocardium obtained with simulations were lower than the corresponding normalized signal intensities obtained in vivo in pigs (p < 0.05, 134% vs 153%) and in patients (p < 0.05, 126% vs 145%). The results from simulations showed a linear relationship to the results obtained in the experimental porcine model (r2 = 0.61) and in patients (r2 = 0.69). CONCLUSION: The T1 and T2 values of remote, salvaged, and infarcted myocardium only partly explain the signal intensities in CE-SSFP images. Bloch simulations suggest that there may be more elements that contribute to the CE-SSFP contrast. Integration of other aspects of the MR experiment into the simulation model could further help to fully unravel the mechanisms of CE-SSFP.

BACKGROUND: Smoking poses the most common risk factor for chronic obstructive pulmonary disease (COPD) and aggravates disease progression. Tobacco dependence inhibits smoking cessation and may affect smoking patterns that increase tobacco exposure and predispose to lung function decline. AIMS AND OBJECTIVES: We aimed to assess tobacco dependence in current smokers with and without COPD and evaluate its role in disease development. METHOD: This cross-sectional study was conducted in Greek rural areas. Current smokers completed the Fagerström Test for Nicotine Dependence and were classified into COPD and non-COPD groups based on spirometry parameters. RESULTS: Among current smokers, 288 participants comprised the non-COPD and 71 the COPD group. Both presented moderate tobacco dependence, but smokers with COPD started to smoke earlier in the morning. Multiple logistic regression analysis revealed higher COPD prevalence in smokers with higher scores in the Fagerström test (odds ratio OR = 1.12, 95% confidence interval [1.01 - 1.24]) and older age (OR = 1.06 [1.03 - 1.09]), independently of pack-years smoking index. Multiple linear regression analysis in smokers with COPD showed that the forced expiratory volume in the 1st second decreased by 2.3% of the predicted value for each point increase in the Fagerström Test and 0.59% for each year of age, independently of participants' sex and pack-years smoking index. CONCLUSION: The Fagerström score appears to indicate a higher probability for COPD and lung function deterioration when assessed along with age in current smokers. Smoking cessation support programs are fundamental to COPD prevention and management.

Randomized controlled trials represent the cornerstone for the regulatory approval of drugs and evidence-based medicine and policy. Compared with observational studies random assignment of participants to each study arm guarantees an equal distribution of potential confounders thus achieving impartiality in the evaluation of between group differences and allowing for causal inferences to be drawn. These complex and costly medical experiments are tightly regulated and require substantial planning with great attention to several methodological aspects ranging from allocation concealment and blinding to sample size estimation, statistical analysis, and handling of protocol deviations. This brief guide offers useful insights into the design, conduct, and interpretation of clinical trial findings for beginners.
RESUMO
Systematic reviews (SRs) have an important role in the healthcare decision-making practice. Assessing the overall confidence in the results of SRs using quality assessment tools, such as "A MeaSurement Tool to Assess Systematic Reviews 2" (AMSTAR 2), is crucial since not all SRs are conducted using the most rigorous methods. In this article, we introduce a free, open-source R package called "amstar2Vis" (https://github.com/bougioukas/amstar2Vis) that provides easy-to-use functions for presenting the critical appraisal of SRs, based on the items of AMSTAR 2 checklist. An illustrative example is outlined, describing the steps involved in creating a detailed table with the item ratings and the overall confidence ratings, generating a stacked bar plot that shows the distribution of ratings as percentages of SRs for each AMSTAR 2 item, and creating a "ggplot2" graph that shows the distribution of overall confidence ratings ("Critically Low," "Low," "Moderate," or "High"). We expect "amstar2Vis" to be useful for overview authors and methodologists who assess the quality of SRs with AMSTAR 2 checklist and facilitate the production of pertinent publication-ready tables and figures. Future research and applications could further investigate the functionality or potential improvements of our package.

OBJECTIVES: To conduct a methodological overview of reviews to evaluate the reporting completeness and transparency of systematic reviews (SRs) of prognostic prediction models (PPMs) for COVID-19. STUDY DESIGN AND SETTING: MEDLINE, Scopus, Cochrane Database of Systematic Reviews, and Epistemonikos (epistemonikos.org) were searched for SRs of PPMs for COVID-19 until December 31, 2022. The risk of bias in systematic reviews tool was used to assess the risk of bias. The protocol for this overview was uploaded in the Open Science Framework (https://osf.io/7y94c). RESULTS: Ten SRs were retrieved; none of them synthesized the results in a meta-analysis. For most of the studies, there was absence of a predefined protocol and missing information on study selection, data collection process, and reporting of primary studies and models included, while only one SR had its data publicly available. In addition, for the majority of the SRs, the overall risk of bias was judged as being high. The overall corrected covered area was 6.3% showing a small amount of overlapping among the SRs. CONCLUSION: The reporting completeness and transparency of SRs of PPMs for COVID-19 was poor. Guidance is urgently required, with increased awareness and education of minimum reporting standards and quality criteria. Specific focus is needed in predefined protocol, information on study selection and data collection process, and in the reporting of findings to improve the quality of SRs of PPMs for COVID-19.

This study aimed to assess the methods and outcomes of The Measurement Tool to Assess systematic Reviews (AMSTAR) 2 appraisals in overviews of reviews (overviews) of interventions in the cardiovascular field and identify factors that are associated with these outcomes. MEDLINE, Scopus, and the Cochrane Database of Systematic Reviews were searched until November 2022. Eligible were overviews of cardiovascular interventions, analyzing systematic reviews (SRs) of randomized controlled trials (RCTs). Extracted data included characteristics of overviews and SRs and AMSTAR 2 appraisal methods and outcomes. Data were synthesized using descriptive statistics and logistic regression to explore potential associations between the characteristics of SRs and extracted AMSTAR 2 overall ratings ("High-Moderate" vs. "Low-Critically low"). The original results on individual AMSTAR 2 items were entered into the official AMSTAR 2 online tool and the recalculated overall confidence ratings were compared to those provided in overviews. All 34 overviews identified were published between 2019 and 2022. Rating of overall confidence following the algorithm suggested by AMSTAR 2 developers was noted in 74% of overviews. The 679 unique included SRs were mainly of "Critically low" (53%) or "Low" (18.7%) confidence and underperformed in items 2 (Protocol, no = 65.2%) and 7 (List of excluded studies, no = 84%). The following characteristics of SRs were significantly associated with higher overall ratings: Cochrane origin, pharmacological interventions, including exclusively RCTs, citation of methodological and reporting guidelines, protocol, absence of funding and publication after AMSTAR 2 release. Generally, overviews' authors tended to deviate from the original rating scheme and ascribe higher ratings to SRs compared to the official AMSTAR 2 online tool. Most SRs included in overviews of cardiovascular interventions have critically low or low confidence in their results. Overviews' authors should be more transparent about the methods used to derive the overall confidence in SRs.

PURPOSE: This study aimed to apply different methods of diagnostic test accuracy network meta-analysis (DTA-NMA) for studies reporting results of five imaging tests for the diagnosis of suspected pulmonary embolism (PE): pulmonary angiography (PA), computed tomography angiography (CTPA), magnetic resonance angiography (MRA), planar ventilation/perfusion (V/Q) scintigraphy and single-photon emission computed tomography ventilation/perfusion (SPECT V/Q). METHODS: We searched four databases (MEDLINE [via PubMed], Cochrane CENTRAL, Scopus, and Epistemonikos) from inception until June 2, 2022 to identify systematic reviews (SRs) describing diagnostic accuracy of PA, CTPA, MRA, V/Q scan and SPECT V/Q for suspected PE. Study-level data were extracted and pooled using a hierarchical summary receiver operating characteristic (HSROC) meta-regression approach and two DTA-NMA models to compare accuracy estimates of different imaging tests. Risk of bias was assessed using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) tool and certainty of evidence using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework. RESULTS: We identified 13 SRs, synthesizing data from 33 primary studies and for four imaging tests (PA, CTPA, MRA and V/Q scan). The HSROC meta-regression model using PA as the reference standard showed that MRA had the best overall diagnostic performance with sensitivity of 0.93 (95% confidence interval [CI]: 0.76, 1.00) and specificity of 0.94 (95% CI: 0.84, 0.99). However, DTA-NMA models indicated that V/Q scan had the highest sensitivity, while CTPA was most specific. CONCLUSION: Selecting a different DTA-NMA method to assess multiple diagnostic tests can affect estimates of diagnostic accuracy. There is no established method, but the choice depends on the data and familiarity with Bayesian statistics.

BACKGROUND: Ovarian senescence is associated with increased cardiovascular risk. We aimed to evaluate the association between menopausal symptoms and cardiometabolic risk factors in a cohort of apparently healthy middle-aged women. METHODS: The cohort included 2793 peri- and postmenopausal women not on menopausal hormone therapy. Demographic/anthropometric and biochemical/hormonal data were assessed. The severity of menopausal symptoms was evaluated by the Greene Climacteric Scale (GCS). RESULTS: GCS-Total Score was associated with BMI (b=0.12, 95% CI: 0.04 to 0.20), T2DM (b=2.10, 95% CI: 0.06 to 4.15), and late-postmenopause (b=-1.24, 95% CI: -2.17 to -0.33). GCS-psychological score was associated with BMI (b=0.06, 95% CI: 0.00 to 0.11). GCS-Physical Score was associated with BMI (b=0.06, 95% CI: 0.03 to 0.09), central obesity (b=0.18, 95% CI: 0.02 to 0.34), and postmenopause (early-/late-postmenopause vs. perimenopause, b=-0.36, 95% CI: -0.59 to -0.13 and b=-0.65, 95% CI: -0.97 to -0.34, respectively). All GCS-scores were negatively associated with age. GCS-Sexual Score was associated with early-postmenopause (incidence rate ratio (IRR)=1.53, 95% CI: 1.21 to 1.94), central obesity (IRR=1.18, 95% CI: 1.00 to 1.39), smoking, diastolic blood pressure, age. Cox-regression analysis showed that incident T2DM was positively associated with increasing age, BMI, daily alcohol consumption, moderate-to-severe vasomotor symptoms (VMS, OR=1.045, 95% CI: 1.011 to 1.079), and negatively with moderate-to-strenuous physical activity. These associations persisted in lean but not in obese women. CONCLUSIONS: The severity of menopausal symptoms is associated with T2DM, obesity, and smoking in a cohort of peri-/postmenopausal women. VMS were associated with incident T2DM, especially in lean women. These associations must be considered in implementing primary and secondary prevention strategies.
RESUMO
Histologic markers of increased risk for hepatocellular carcinoma can provide useful information for the management of patients with chronic hepatitis B. The expression of epithelial cell adhesion molecule (EpCAM, a marker of hepatic progenitor cells), p21 (a marker of hepatocyte senescence), glutamine synthetase (a marker of perivenular hepatocytes) and CD34 (a marker of sinusoidal capillarization) were assessed by immunohistochemistry in 52 liver biopsy specimens from patients with advanced stage chronic hepatitis B. Nineteen patients developed hepatocellular carcinoma during a follow-up period of 133 months. The findings were compared with those of 18 liver biopsy specimens from patients with early-stage chronic hepatitis B and 6 liver biopsy specimens without significant pathologic findings. EpCAM expression in hepatocytes was significantly increased in specimens with advanced stage, as compared with all other specimens. EpCAM positivity in over 30 % of hepatocytes was only seen in 3 specimens from patients who subsequently developed hepatocellular carcinoma. The expression of p21, glutamine synthetase and CD34 was not associated with hepatocellular carcinoma development. Nevertheless, glutamine synthetase immunostains highlighted zonality abnormalities that were useful in chronic hepatitis B staging. In conclusion, extensive immunopositivity of hepatocytes for EpCAM in chronic hepatitis B may represent a marker of increased hepatocellular carcinoma risk. Glutamine synthetase immunostaining represents a useful adjunct in determining the stage of chronic hepatitis B in diagnostic practice.

The International Federation of Gynecology and Obstetrics (FIGO) nutrition checklist is a tool for everyday antenatal clinical practice, easy to use by most healthcare professionals, aiming to initiate a conversation regarding gestational weight gain (GWG) and nutrition and identify women who might require further assessment. The present cross-sectional study aimed to apply the FIGO nutrition checklist to pregnant women attending routine antenatal care and identify nutritional risk factors. Pregnant women (n = 200) were recruited from the outpatient pregnancy clinics of two hospitals in Thessaloniki and completed the checklist. The FIGO-diet quality score and the FIGO-nutritional risk score (NRS) were calculated. The results revealed that 99% of the women exhibited at least one nutritional risk factor based on the checklist. The median FIGO diet quality score of the sample was 4.0 (3.0-5.0), with 95% of the participants responding negatively to at least one question, indicating the need for improving diet quality. Improved diet quality was noted in cases of hyperemesis gravidarum and among those receiving vitamin D supplements. A large percentage of the participants (36%) exhibited five or more nutritional risk factors, as indicated by a total FIGO-NRS below 5. Women with low middle-upper arm circumference, indicative of protein-energy malnutrition (20.6% of the sample), exhibited more nutritional risk factors compared with the rest. On the other hand, being in the third trimester of pregnancy was associated with lower nutritional risk and, subsequently, better diet quality.

This systematic review and meta-analysis aims to evaluate the predictive value of total atrial conduction time (TACT) assessed by tissue Doppler echocardiography (PA-TDI) in atrial fibrillation (AF) recurrence in patients following a rhythm-control strategy. A systematic approach following Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines was applied in electronic databases (Pubmed, Cochrane Library, and Web of Science), supplemented by scanning through studies' references. TACT was compared using a random-effects model and presented as a difference in means (MD). The primary endpoint was AF recurrence. Seven publications were included in this systematic review. The mean age of the patients ranged from 55 years to 72 years. Prolonged TACT was associated with AF recurrence [MD, 23.12 msec; 95% confidence interval (CI), 11.54-34.71; I2 = 95%]. Subgroup analysis showed that prolonged TACT was strongly associated with AF recurrence in persistent AF cohorts undergoing electrical cardioversion (MD, 26.56; 95% CI, 15.51-37.6; I2 = 86%), while in patients with paroxysmal AF (PAF) undergoing catheter ablation, the results were not statistically significant (MD, 11.48; 95% CI, -1.19 to 24.14; I2 = 90%). The summary area under the curve (sAUC) using a random-effects model was 0.89 (95% CI, 0.80-0.99). TACT is a valuable echocardiographic parameter that can predict AF recurrence in patients following a rhythm-control strategy.

RESUMO
Pacing indications in children are clearly defined, but whether an epicardial (EPI) or an endocardial (ENDO) pacemaker performs better remains to be elucidated. This systematic review and meta-analysis aimed to directly compare the incidence of pacemaker (PM) lead-related complications, mortality, hemothorax and venous occlusion between EPI and ENDO in children with atrioventricular block (AVB) or sinus node dysfunction (SND). Literature search was conducted in MEDLINE (via PubMed), Scopus by ELSEVIER, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and OpenGrey databases until June 25, 2022. Random-effects meta-analyses were performed to assess the pacing method's effect on lead failure, threshold rise, post-implantation infection and battery depletion and secondarily on all-cause mortality, hemothorax and venous occlusion. Several sensitivity analyses were also performed. Of 22 studies initially retrieved, 18 were deemed eligible for systematic review and 15 for meta-analysis. Of 1348 pediatric patients that underwent EPI or ENDO implantation, 542 (40.2%) had a diagnosis of congenital heart disease (CHD). EPI was significantly associated with higher possibility of PM-lead failure [pooled odds ratio (pOR) 3.00, 95% confidence interval (CI) 2.05-4.39; I2 = 0%]; while possibility for threshold rise, post-implantation infection and battery depletion did not differ between the PM types. Regarding the secondary outcome, the mortality rates between EPI and ENDO did not differ. In sensitivity analyses the results were consistent results between the two PM types. The findings suggest that EPI may be associated with increased PM-lead failure compared to ENDO while threshold rise, infection, battery depletion and mortality rates did not differ.

BACKGROUND/AIM: COVID-19 has dramatically impacted non-pandemic-related care, including preventive medicine. Our objective was to quantify the alterations in the volume of screening tests for breast and cervical cancer during the COVID-19 era compared to pre-pandemic levels. Secondarily, we discussed the causes responsible for this change, presented suggestions for screening optimization and conducted a targeted search of the relevant literature for worsening of future mortality due to screening setback. MATERIALS AND METHODS: We systematically searched Pubmed, Google Scholar and Epistemonikos for articles in English or Greek, published from March 11th, 2020, until September 14th, 2022, that illustrated quantitative variations of mammograms or Pap/HPV tests. Preprint articles, editorials and speeches were excluded. Quality of included studies was assessed via the JBI critical appraisal checklist for studies reporting prevalence data. The evidence was narratively synthesized. RESULTS: A total of 56 articles were included, being either observational studies or reports from cancer registries. Large reductions were universally identified, peaked during the first wave but partially persisted after easing of the restrictions. CONCLUSION: Our systematic review provides an updated record of the variations in screening volume and approaches screening neglect from a multidimensional perspective answering why it happened and how we could achieve recovery. A strong awareness campaign is proposed, in conjunction with triaging citizens more likely to benefit from screening. Cervical self-sampling is emphasized in the literature. Various studies displayed a potential increase in cancer mortality in the future based on predictive statistical models.

Pandemics precipitate feelings of discomfort and anxiety in healthcare professionals. This study investigates the prevalence of anxiety and depression among public primary health care professionals (PHCPs) in Greece, along with the demographic risk factors, during the second wave of the COVID-19 pandemic, in order to address work exhaustion and protect frontline professionals' psycho-emotional balance. This cross-sectional study was conducted from June 2021 to August 2021, using an online questionnaire (demographic data, GAD-7, PHQ-9). Eligible participants (medical, nursing, allied professionals) were PHCPs employed in Greek public PHC facilities. Analysis involved descriptive statistics to present sociodemographic characteristics, participants' experience with COVID-19, anxiety and depression levels. Univariate analysis was performed to evaluate the association between sociodemographic factors and the anxiety and depression levels, and multivariable logistic regression was used to investigate the presence of predictive factors for anxiety and depression. In total, 236 PHCPs participated in the study, with a mean age of 46 (SD 9.3) years and a mean professional experience of 14.71 (SD 9.2) years. Most participants were women (71.4%) and the majority were General Practitioners (38.9%) and Nurses (35.2%). Anxiety (33.1% mild, 29.9% moderate/ severe) and depression (33.9% mild, 25.9% moderate/ severe) were prevalent among PHCPs. The female gender is the most important predictor of anxiety manifestations (OR:3.50, 95%CI:1.39-10.7; p=0.014). Participants older than 50 years have a lower risk of both anxiety (OR=0.46, 95%CI:0.20-0.99; p=0.049) and depression (OR=0.48, 95%CI:0.23-0.95; p=0.039). PHCPs working in rural facilities have a lower risk of anxiety (OR:0.34, 95%CI:0.137-0.80; p=0.016). Previous infection with SARS-CoV-2 was not associated either with anxiety (p=0.087) or with depression (p=0.056). Notably, having a friend, relative, or coworker who was hospitalized for COVID-19 or died from it, was not associated with the presence of anxiety or depressive symptoms. Additionally, living with someone in a high-risk group for severe SARS-CoV-2, living with children or being at high risk for severe COVID-19 was not associated with higher GAD-7 and PHQ-9 scores. Findings indicate concerning levels of psychological distress among PHCPs. Early recognition of emotional discomfort in PHCPs and the prompt intervention could reinforce PHCPs' resilience against the pandemic.
RESUMO
OBJECTIVES: This study aimed to evaluate the epidemiology, reporting characteristics, and adherence to the Preferred Reporting Items for Overviews of Reviews (PRIOR) statement of overviews of reviews (overviews) of interventions in the cardiovascular field. STUDY DESIGN AND SETTING: MEDLINE, Scopus, and the Cochrane Database of Systematic Reviews were searched from January 1, 2000, to October 15, 2020. An updated search was performed in MEDLINE, Epistemonikos, and Google Scholar up to August 25, 2022. Overviews of interventions published in English and primarily considering populations, interventions, and outcomes pertinent to the cardiovascular field were eligible. Study selection, data extraction, and PRIOR adherence assessment were performed by two authors independently. RESULTS: We analyzed 96 overviews. Almost half (43/96 [45%]) were published between 2020 and 2022 and contained a median of 15 systematic reviews (SRs) (interquartile range, 9-28). The commonest title terminology was "overview of (systematic) reviews" (38/96 [40%]). Methods for handling SR overlap were reported in 24/96 (25%), methods for assessing primary study overlap in 18/96 (19%), handling of discrepant data in 11/96 (11%), and methods for methodological quality or risk of bias assessment of the primary studies within SRs in 23/96 (24%). Authors included data sharing statements in 28/96 (29%), complete funding disclosure in 43/96 (45%), protocol registration in 43/96 (45%), and conflict of interest statement in 82/96 (85%) overviews. CONCLUSION: Insufficient reporting was identified in methodological characteristics unique in overviews' conduct and most transparency markers. Adoption of PRIOR from the research community could ameliorate overviews' reporting.

OBJECTIVE: Halting and reversing glaucoma therapy-related ocular surface disease (GTR-OSD) will improve the success of long-term medical therapy, impacting millions of patients worldwide. METHODS: A single-centre, masked, prospective, placebo-controlled, crossover trial of 41 well-controlled open-angle glaucoma subjects with moderate to severe GTR-OSD on preserved latanoprost and dorzolamide/timolol fixed combination (DTFC) therapy was conducted. Subjects were randomized to preservative-free (PF) tafluprost and DTFC with either placebo or cyclosporine 0.1% drops for 6 months and were then crossed over to the opposite therapy. Oxford score of ocular staining was the primary outcome; osmolarity, matrix-metalloproteinase-9 (MMP-9) testing, tear film break-up time (TFBUT), meibomian gland dysfunction (MGD), punctum evaluation, adverse events and diurnal intraocular pressure (IOP) comprised secondary outcomes. RESULTS: GTR-OSD findings improved with PF therapy. At 6 months the triple PF with placebo group showed improvement compared to baseline in mean Oxford score (mean difference [MD]:-3.76; 95% confidence interval [CI]:-4.74 to -2.77; p < 0.001), osmolarity (MD:-21.93; 95%CI:-27.61 to -16.24 mOsm/l; p < 0.001), punctum stenosis (p = 0.008) and conjunctival hyperaemia (p < 0.001). Similar improvements occurred in the cyclosporine enhanced period, which also provided greater improvement in MMP-9 positivity (24 vs 66%; p < 0.001) and TFBUT (p = 0.022). The cyclosporine group was superior vs placebo in mean Oxford score (MD:-0.78; 95%CI:-1.40 to -0.15); p < 0.001), itchiness and objective adverse events (p = 0.034). Cyclosporine elicited more stinging vs placebo (63 vs 24%; p < 0.001). Both PF regimens reduced mean diurnal IOP more than preserved therapy (14.7 vs 15.9 mmHg; p < 0.001). CONCLUSIONS: Changing from preserved to PF glaucoma medications improves ocular surface health and IOP control. Topical cyclosporine 0.1% further reverses GTR-OSD.
