Maintenance of weight loss is hard to achieve, and novel interventions are needed to improve long-term outcomes. In this pilot randomized controlled trial, N = 188 participants received an online, 12-week weight loss intervention and N = 102 who lost ≥ 5% were then randomly assigned to a 1-day, 5-h workshop based on Acceptance and Commitment Therapy (ACT), Self-Regulation (SR), or no workshop (Control) with 3 months of limited email follow-up. Assessments were conducted at baseline, 3, 6, 12, 18, and 24 months. The primary outcome was percent weight change; secondary outcomes were weight-related experiential avoidance and health values-consistent behavior. ACT had greater overall weight loss (-7.18%, SE = 1.33) when compared to Control (-1.15%, SE = 1.50; p = .03). Post hoc analyses showed that ACT had significantly greater weight losses than Control (6.11%, β = -2.03, p = .048) among those with lower initial weight loss (5-7%), and significantly greater weight loss than SR (6.19%, β = -1.77, p = .05) among those with the highest initial weight losses (10% +). There is potential for continuing to develop ACT in a limited interventionist-contact format with modifications. This pilot study represents an innovative model for behavioral weight loss by reversing the typical treatment intensity model with the aim of providing interventionist support during a critical period after initial weight loss.

To investigate topographic, tomographic, topometric, densitometric, and aberrometric parameters in subclinical keratoconus with the Pentacam HR imaging system.

Data of 3128 patients were evaluated, finding in 108 patients clinical keratoconus in one eye and subclinical keratoconus in the other. Corneal topographic, tomographic, topometric, densitometric, and aberrometric values obtained using the Pentacam HR imaging system were compared between clinical keratoconus, subclinical keratoconus, and normal eyes.

Comparing eyes with subclinical keratoconus and the control group, while flat K, horizontal coma, horizontal trefoil, and vertical trefoil values were similar (p > 0.05 for each), all other parameters were significantly different (p < 0.05 for each). Densitometry values of eyes with subclinical keratoconus were significantly higher in all layers of the 0-2mm annular area and in the anterior and central layers of the 2-6mm annular area compared to the control group (p < 0.05 for each). According to the receiver operating characteristic curve analysis, the densitometry region with the largest area under the curve was the anterior layer of the 0-2mm annular area. The sensitivity in this region was 79.4% and the specificity 73.2% in distinguishing eyes with subclinical keratoconus from normal eyes when 19.3 GSU was considered the threshold.

Corneal densitometry values in the 0-2 and 2-6mm annular areas, especially in the anterior layers, are parameters that can be used to predict and distinguish subclinical keratoconus from normal eyes.

The purpose of this study was to screen target miRNA related to RB and explore the expression levels of target miRNA in RB and its potential value of diagnosis.

The Affymetrix GeneChip miRNA 4.0 Array was used to screen the differential miRNAs in the plasma of 5 RB patients before and after intravenous chemotherapy, and the most significant down-regulated miRNA was selected for target miRNA. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) is used to verify the expression levels of plasma target miRNA in 30 RB patients. Then, qRT-PCR was performed to further verify the expression of target miRNA in plasma of RB patients and RB tumor tissues. Finally, receiver-operating-characteristic (ROC) curve and the area under the ROC curve (AUC) were used to evaluate the diagnostic power of plasma target miRNA.

The miRNA Array obtain 8 core miRNAs, 1 up-regulated and 7 down-regulated, of which miR-6089 was the most significantly down-regulated. Plasma miR-6089 levels were significantly up-regulated in RB patients. Besides, in RB tumor tissues, miR-6089 levels were also obviouslyup-regulated. After intravenous chemotherapy, the expression of plasma miR-6089 was significantly decreased. Furthermore, ROC curve analysis showed that miR-6089 in the plasma had a good sensitivity and specificity for distinguishing RB from the healthy control group.

MiR-6089 may be considered as a novel potential diagnostic biomarker for RB.

To evaluate whether anti-vascular endothelial growth factor (VEGF) therapy combined with panretinal photocoagulation could reverse diabetic retinopathy (DR).

Fifty-two patients (72 eyes) with high-risk proliferative DR who were diagnosed and treated from June 2018 to May 2019 were divided into the laser group (16 cases, 32 eyes) and combination group (36 cases, 40 eyes) according to a review of the medical records.

Within-group comparison There were no significant differences in best-corrected visual acuity (BCVA), central foveal thickness (CFT), and microaneurysms in the laser group before and after treatment, but there were statistically significant improvements in the combination group. After the treatment, the BCVA of the patients in the combination group was 0.44 ± 0.17, which was significantly better than 0.70 ± 0.18 before treatment; the CFT after treatment was 266.51 ± 33.28μm, which was significantly lower than 382.37 ± 54.03μm at baseline; the MA after treatment was 56.12 ± 23.29, which was significantly lower than 121.44 ± 40.35. There was a statistically significant decrease in hard exudates area in both two groups before and after treatment. Comparison between groups The difference in BCVA, CFT, MA and between the two groups was statistically significant (all P < 0.05), and the area of retinal neovascularization between the two groups was no significant difference, but decreased more rapidly in the combination group than that in the laser group.

Using intravitreal injection of anti-VEGF drugs combined with panretinal photocoagulation to treat DR might morphologically and functionally reverse retinal changes caused by diabetes mellitus.

To evaluate the outcome and safety of implantable collamer lens (ICL; (Visian, STAAR Surgical, Monrovia, CA, USA) in mild to advance keratoconus patients with myopia and myopic astigmatism.

This retrospective study evaluated all patients who underwent ICL implantation for the management of keratoconus at a tertiary care eye hospital from January 2012 to January 2018. The mean duration of follow-up was 15.3months (range, 3.13 to 38.97months). Data were collected on preoperative and postoperative uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), refraction was compared, and adverse effects were evaluated.

Thirty-two eyes (32 patients) were evaluated. The median CDVA was 20/30 preoperatively and 20/20 at last follow-up. The median UDVA was 20/25 at last follow-up. Thirteen patients (40.6%) had 20/20 UDVA in comparison to none at baseline. The median spherical equivalent in diopters (D) was -7.875 D (-4.125 to -10.0 D) preoperatively and decreased to -0.3125 D at last fonecessary for achieving good outcomes and mitigating intraoperative and postoperative complications.Patient navigation is a promising strategy for improving health among persons with multiple barriers to HIV care, yet little is known about navigation's core components. GC7 order From 24 systematically identified navigation studies, we abstracted navigators' activities, grouped activities into 20 thematic activity categories, and ordered them by frequency. Subsequently, Principal Components Analysis of activity categories was used identify independent clusters. Accompaniment characterized 71% of navigation programs; ≥ half included health education (58%), collaboration/coordination (58%), linkage-to-care (54%), transportation support (54%), service referrals (50%) and instrumental support (50%). Five unique components (comprising 13 activity categories) were identified (1) services beyond office, (2) health education and relationship building, (3) accompaniment and instrumental support, (4) locating patients and tracking information, and (5) beyond HIV care. Navigators who located patients or tracked information were less likely to provide accompaniment or instrumental support (r = - 0.60, p = 0.002). Findings can enhance precision in developing, describing, evaluating and improving navigation programs.Longitudinal qualitative research can provide rich understanding of the life circumstances of vulnerable groups who experience health inequities, of whether, how and why these circumstances change, and of how these circumstances and processes of change impact health. But, this rich understanding is not automatic and requires systematic and thoughtful approaches to data collection and analysis. The purpose of this paper is to describe two longitudinal qualitative studies embedded in mixed-methods studies of social determinants of HIV in the United States and the Dominican Republic. We compare these two studies to critically reflect on specific techniques that facilitate longitudinal and iterative data collection, management, and analysis, in particular the use of participant-specific matrices and analytic summaries across the distinct phases of the research. We conclude that combining cross-sectional and longitudinal analysis that engages with both themes and processes of change can contribute to improved contextualization and understanding of social determinants of HIV.Young adolescents in Sub-Saharan Africa (SSA) are at high risk of involvement in sexual risk behaviors; and curable sexually transmitted infections (STI), herpes simplex virus type 2 (HSV-2), human immunodeficiency virus (HIV) and unintended pregnancies remain persistently high in this population. Evidence based strategies are urgently needed to improve these outcomes. The aim of this systematic review was to synthesize the evidence from randomized controlled trials (RCT) to determine whether school-based interventions promote safe sex behaviors, reduce sexual risk behaviors and risk of curable STIs, HSV-2, HIV and unintended pregnancies among young adolescents aged 9-19 years in SSA. Electronic databases were searched for published studies and manual searches were conducted through reviewing of references of cited literature in the English language up to December 2019. Two independent reviewers screened and abstracted the data. We identified 428 articles and data from nine RCTs (N = 14,426 secondary school students) that fulfilled the selection criteria were analysed.
