A Randomized, Parallel Design Study to Evaluate the Effects of Different Oral Cleaning Modalities on Gingivitis and Plaque After a 6-Week Period of Home Use.

The study objective was to evaluate the effect of different interdental oral cleaning modalities on gingivitis and plaque following a 6-week period of home use. This was a randomized, parallel, examiner-blinded study. Study subjects were routine manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have a minimum average plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to one of four groups based on the oral care cleaning modality: (1) NON group: MTB alone, (2) FLS group: MTB plus string floss, (3) MPF group: MTB plus a Philips® Sonicare® Power Flosser with the Quad Stream nozzle, or (4) PPF group: Philips Sonicare power toothbrush plus the power flosser. Safety and efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) were assessed at baseline, 2 weeks, and 6 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 6 as measured by the MGI. A total of 260 subjects were randomized and 256 subjects completed the study. The adjusted mean percent reduction in gingival inflammation from baseline to week 6 was 14.90% for the NON group, 13.16% for the FLS group, 33.51% for the MPF group, and 49.30% for the PPF group. Pairwise comparisons indicated that both the PPF and MPF groups were statistically significantly different from both the NON and FLS groups. In conclusion, use of either the Philips Sonicare power toothbrush with the Philips Sonicare Power Flosser or an MTB with the Philips Sonicare Power Flosser was statistically superior to an MTB alone and an MTB used with string floss in reducing gingival inflammation following 6 weeks of home use.

Disease-modifying effects of ranibizumab for central retinal vein occlusion.

PURPOSE: To identify anatomic endpoints altered by intravitreal ranibizumab in central retinal vein occlusion (CRVO) to determine any potential underlying disease modification that occurs with anti-vascular endothelial growth factor (anti-VEGF) therapy beyond best-corrected visual acuity and central optical coherence tomography outcomes. METHODS: A post hoc analysis of a double-masked, multicenter, randomized clinical trial was performed. A total of 392 patients with macular edema after CRVO were randomized 1:1:1 to receive monthly intraocular injections of 0.3 or 0.5 mg of ranibizumab or sham injections. Central reading center-read data were reviewed to explore potential anatomic endpoints altered by therapy. RESULTS: At 6 months, there was a reduction in the ranibizumab groups compared with sham groups with respect to total area of retinal hemorrhage (median change from baseline in disc areas: - 1.17 [sham], - 2.37 [ranibizumab 0.3 mg], - 1.64 [ranibizumab 0.5 mg]), development of disc neovascularization (prevalence: 3% [sham], 0% [ranibizumab 0.3 mg], 0% [ranibizumab 0.5 mg]), and presence of papillary swelling (prevalence: 22.9% [sham], 8.0% [ranibizumab 0.3 mg], 8.3% [ranibizumab 0.5 mg], p < 0.01). There was no difference between groups in collateral vessel formation. Analysis of vitreous and preretinal hemorrhage could not be performed due to low frequency of events in both treated and sham groups. CONCLUSIONS: Ranibizumab for CRVO resulted in beneficial disease-modifying effects through a reduction in retinal hemorrhage, neovascularization, and papillary swelling. These findings may form the basis for future work in the development of a treatment response or severity scale for eyes with CRVO.

Primary hemiarthroplasty after unstable trochanteric fracture in elderly patients: mortality, readmission and reoperation.

BACKGROUND: Most unstable trochanteric fractures are treated with internal fixation and often with high complication rates. Hemiarthroplasty might be an alternative method in difficult condition, especially in unstable comminuted fracture in fragile bone. However, few have investigated the long-term outcomes after hemiarthroplasty for unstable trochanteric fracture. We conducted a population-based retrospective cohort study of trochanteric fracture after primary hemiarthroplasty using competing risk analysis on their long-term outcomes, including mortality, readmission and reoperation. METHODS: We studied a total of 2798 patients over 60 years old, with a mean age of 79 years, of which 68% are females and 67.23% have at least one comorbidity. They underwent a hemiarthroplasty for unstable trochanteric fracture during the period between January 1, 2000 and December 31, 2010 and were follow-up until the end of 2012, or death. Survival analysis and Cox model were used to characterize mortality. Competing risk analysis and Fine and Gray model were used to estimate the cumulative incidences of the first readmission and the first reoperation. RESULTS: The follow-up mortality rate for 1-year was 17.94%; 2-year, 29.76%; 5-year, 56.8%; and 10-year, 83.38%. The cumulative incidence of the first readmission was 16.4% for 1-year and 22.44% for 3-year. The cumulative incidence of the first reoperation was 13.87% for 1-year, 18.11% for 2-year, 25.79% for 5-year, and 38.24% for 10-year. Male gender, older age, higher Charlson Comorbidity Index (CCI) and lower insured amount were all risk factors for the overall mortality. Older age and higher CCI were risk factors for the first readmission. Older age was a protective factor for reoperation, which is likely due to the competing death. CONCLUSIONS: The mortality and revision rates after hemiarthroplasty for unstable trochanteric fracture are acceptable as a salvage procedure for this fragile sub-population.

Panretinal Photocoagulation for Diabetic Retinopathy in the RIDE and RISE Trials: Not "1 and Done".

PURPOSE: To evaluate panretinal photocoagulation (PRP) treatment and re-treatment patterns in patients with diabetic retinopathy (DR) and diabetic macular edema (DME). DESIGN: Post hoc analysis of the phase 3 RIDE (clinicaltrials.gov identifier, NCT00473382) and RISE (clinicaltrials.gov identifier, NCT00473330) clinical trials of ranibizumab for the treatment of DME. PARTICIPANTS: Seven hundred fifty-nine patients were randomized for treatment. METHODS: Panretinal photocoagulation treatment patterns and clinical experiences were assessed by baseline PRP treatment status. MAIN OUTCOME MEASURES: Number and timing of on-study PRP treatment sessions undergone through month 24. Time to new proliferative event (composite end point) was also assessed. RESULTS: At baseline, approximately 25% of patients in RIDE and RISE had undergone PRP treatment before enrollment (22.2%, 24.4%, and 25.4% of patients in the sham, ranibizumab 0.3 mg, and ranibizumab 0.5 mg arms, respectively). In patients without prior PRP at baseline (n = 577), 9.5% of sham-treated patients underwent 1 or more PRP treatments through month 24, compared with 1.1% and 1.6% of patients receiving ranibizumab 0.3 mg and ranibizumab 0.5 mg, respectively (P < 0.001 for both ranibizumab arms vs. sham). In patients with prior PRP at baseline (n = 182), 19.3% of sham-treated patients underwent 1 or more PRP treatments through month 24. No ranibizumab-treated patients with prior PRP at baseline required additional on-study PRP through month 24 (P < 0.001 for both ranibizumab arms vs. sham). Ranibizumab treatment also significantly reduced clinical DR progression among patients who underwent prior PRP. By month 24 in patients with prior PRP at baseline, the probability of experiencing a new proliferative event was 10.3% and 9.9% in patients receiving ranibizumab 0.3 mg and ranibizumab 0.5 mg treatment, respectively, compared with 39.4% in sham-treated patients (P < 0.0001). Overall, sham-treated patients, including those patients who were PRP naïve at baseline who went on to require PRP, experienced more clinical events than ranibizumab-treated patients. CONCLUSIONS: In RIDE and RISE, PRP treatment was not a "1 and done" procedure, with on-study PRP re-treatment occurring in patients both with and without prior PRP treatment at baseline. Ranibizumab treatment reduced on-study PRP treatment and DR progression regardless of prior PRP treatment status at baseline.

Long-Term Vision Outcomes in Patients With DME and a Limited Early Visual Response to Ranibizumab in RIDE and RISE.

BACKGROUND AND OBJECTIVE: To compare early and long-term visual responses to ranibizumab in patients with diabetic macular edema. PATIENTS AND METHODS: Retrospective analysis of RIDE (NCT00473382) and RISE (NCT00473330). Vision outcomes over 36 months were compared between limited early gainers (gained ≤ 5 Early Treatment Diabetic Retinopathy Study [ETDRS] letters), early 1-line gainers (gained 6 to 9 ETDRS letters), and early 2-or-more-line gainers (gained ≥ 10 ETDRS letters) at Month 3. RESULTS: Among 235 ranibizumab-treated patients, 42.6%, 20.0%, and 37.4% were limited early gainers, early 1-line gainers, and early 2-or-more-line gainers, respectively. At Month 36, 71.3% of limited early gainers achieved 6 to 9 and 10 or more ETDRS letter gains. Mean ETDRS letter scores at Month 36 were comparable between limited early gainers (67.8), early 1-line gainers (73.4), and early 2-or-more-line gainers (71.6). CONCLUSION: Clinically meaningful vision outcomes were achieved with long-term ranibizumab treatment, irrespective of early visual acuity response.

Spectral-Domain OCT Predictors of Visual Outcomes after Ranibizumab Treatment for Macular Edema Resulting from Retinal Vein Occlusion.

PURPOSE: To evaluate spectral-domain (SD)-OCT features associated with baseline vision and visual outcomes in the prospective, multicenter Study Evaluating Dosing Regimens for Treatment with Intravitreal Ranibizumab Injections in Subjects with Macular Edema following Retinal Vein Occlusion (SHORE). DESIGN: Post hoc analysis of prospective clinical trial data. PARTICIPANTS: Two hundred two participants in the 15-month, phase 4 SHORE study comparing monthly versus pro re nata ranibizumab after 7 monthly doses in eyes with retinal vein occlusion (RVO) with macular edema. METHODS: Baseline SD-OCT images were assessed for (1) central subfield thickness (CST); (2) presence of vitreomacular adhesion, vitreomacular traction, or epiretinal membrane; (3) presence, location, and amount of intraretinal fluid or subretinal fluid (SRF); (4) presence, location, and amount of hyperreflective foci (HF); (5) disorganization of retinal inner layers (DRIL); and (6) disruption of external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). Univariate and multivariate regression analyses were performed to evaluate the association of these features with baseline best-corrected visual acuity (BCVA) and change in BCVA after 7 monthly ranibizumab injections. MAIN OUTCOME MEASURES: Association of SD-OCT features with baseline BCVA and change in BCVA after 7 monthly ranibizumab injections. RESULTS: Before therapy, worse baseline BCVA was associated with ERM presence (P = 0.0045), thicker SRF (P = 0.0006), larger intraretinal cysts (P = 0.0015), and higher percentage of DRIL (P < 0.0001), percentage of ELM disruption (P < 0.0001), percentage of EZ disruption (P = 0.0003), and percentage of IZ disruption (P = 0.0018). In multivariate models, only percentage of ELM disruption independently impacted baseline BCVA (P < 0.0001). After 7 monthly ranibizumab injections, mean BCVA improved by 18.3±12.6 Early Treatment Diabetic Retinopathy Study letters in treated eyes. The only factors independently associated with BCVA gain after 7 monthly ranibizumab treatments were younger age (P < 0.0001) and worse baseline BCVA (P < 0.0001). CONCLUSIONS: Although SD-OCT features may be associated with presenting vision in eyes with macular edema and RVO, most eyes treated with ranibizumab achieve substantial vision gains, and only older age and better baseline BCVA limited visual improvements.

Different Factors Associated with 2-Year Outcomes in Patients with Branch versus Central Retinal Vein Occlusion Treated with Ranibizumab.

PURPOSE: To investigate characteristics associated with visual and anatomic outcomes in branch and central retinal vein occlusion (BRVO and CRVO) patients treated with ranibizumab. DESIGN: Post hoc analysis of patients with BRVO and CRVO from 2 multicenter clinical trials who completed month 12 of the HORIZON extension trial. PARTICIPANTS: 205 patients with BRVO and 181 patients with CRVO who completed month 12 of the extension trial. METHODS: With the use of logistic regression, covariates with a P value < 0.20 from univariate analysis were included in multivariate models to identify independent factors associated with a given outcome (at P < 0.05), with preset variables of disease duration and original treatment assignment. MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA) ≥20/40 (≥70 letters), gain ≥15 letters, and central subfield thickness (CST) ≤250 µm at HORIZON month 12. RESULTS: In patients with BRVO, good baseline BCVA (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.30-1.79), male sex (OR, 2.48; 95% CI, 1.20-5.13), and normal hematocrit (low vs. normal, OR, 0.26; 95% CI, 0.12-0.59) predicted BCVA ≥20/40; high central foveal thickness (OR, 1.03; 95% CI, 1.01-1.04) and normal hematocrit (low vs. normal, OR, 0.31; 95% CI, 0.15-0.66) predicted BCVA improvement ≥15 letters; and extensive baseline subretinal fluid modestly predicted CST ≤250 µm (OR, 1.08; 95% CI, 1.00-1.16). In patients with CRVO, good baseline BCVA (OR, 1.59; 95% CI, 1.35-1.89), never smoking (OR, 2.80; 95% CI, 1.27-6.17), and young age (OR, 0.58; 95% CI, 0.41-0.82) predicted BCVA ≥20/40; never smoking (OR, 2.13; 95% CI, 1.03-4.39), young age (OR, 0.41; 95% CI, 0.28-0.59), poor baseline BCVA (OR, 0.82; 95% CI, 0.73-0.93), hypertension (OR, 4.47; 95% CI, 1.70-11.75), and low diastolic ocular perfusion pressure (OPP) throughout the study (OR, 0.39; 95% CI, 0.21-0.72) predicted BCVA improvement ≥15 letters; and young age (OR, 0.65; 95% CI, 0.47-0.90), lower mean hematocrit (low vs. normal, OR, 2.81; 95% CI, 1.06-7.49), high systolic OPP throughout the study (OR, 1.61; 95% CI, 1.14-2.27), large areas of central hemorrhage (OR, 1.44; 95% CI, 1.04-2.00), and no subretinal fluid (OR, 2.15; 95% CI, 1.06-4.40) predicted CST ≤250 µm. CONCLUSIONS: There are substantial differences in good outcome factors in CRVO versus BRVO, suggesting differences in pathophysiology. Young age, never smoking, hemodilution, and hypertension/high systolic perfusion pressure are more beneficial in CRVO, suggesting that avoidance of sluggish blood flow and maintenance of perfusion may be particularly important in CRVO.

Baseline characteristics associated with early visual acuity gains after ranibizumab treatment for retinal vein occlusion.

BACKGROUND: To identify baseline patient characteristics associated with early clinically significant visual acuity (VA) improvements within 3 months of treatment initiation in ranibizumab-treated patients with retinal vein occlusion (RVO) in the SHORE study. METHODS: Post hoc analysis of baseline patient characteristics in the randomized, open-label, vision examiner-masked SHORE phase 4 study that compared monthly versus pro re nata dosing of ranibizumab in patients with branch and central RVO. Patients who enrolled in SHORE fulfilled eligibility criteria per protocol (N = 202). SHORE data were retrospectively analyzed to identify baseline patient characteristics associated with early clinically significant improvements in VA, defined as improvement to a Snellen equivalent of 20/40 or better vision (≥ 69 Early Treatment Diabetic Retinopathy Study [ETDRS] letters) or an increase in best-corrected VA (BCVA) of 15 or more ETDRS letters from baseline within 3 months of treatment initiation. Main outcome measures were BCVA gain of 15 or more ETDRS letters from baseline, Snellen equivalent of 20/40 or better vision, and baseline factors associated with early clinically significant improvement in BCVA. RESULTS: The median time for patients to achieve a BCVA of 20/40 or better was 59 days and the median time for patients to gain 15 or more ETDRS letters was 63 days. Better baseline BCVA (> 50 ETDRS letters/Snellen equivalent ≥ 20/100), greater baseline total macular volume (> 9.99 mm3), and presence of subretinal fluid at baseline were all associated with early improvement to 20/40 or better vision (ETDRS equivalent ≥ 69 letters; P < .0001, P = .02, and P = .03, respectively). CONCLUSIONS: This retrospective analysis found that better BCVA, greater total macular volume, and presence of subretinal fluid at baseline were associated with more rapid vision gains. Clinicians may find these helpful when considering the likelihood of achieving early clinically significant VA improvements with ranibizumab in patients with RVO.

Durability of Diabetic Retinopathy Improvement with As-Needed Ranibizumab: Open-Label Extension of RIDE and RISE Studies.

PURPOSE: To evaluate the durability of diabetic retinopathy (DR) improvements after a change in ranibizumab dosing from monthly to individualized pro re nata (PRN) therapy. DESIGN: Pooled analysis of the open-label extension (OLE) of RIDE and RISE (clinicaltrials.gov identifiers, NCT00473382 and NCT00473330) patients with DR and diabetic macular edema (DME). PARTICIPANTS: Patients who completed 36-month participation in RIDE and RISE and entered the OLE. METHODS: In RIDE and RISE, patients (n = 759) were randomized 1:1:1 to ranibizumab 0.3 mg monthly, 0.5 mg monthly, or monthly sham injections with rescue macular laser available after 6 months, per protocol-specified criteria. After 24 months, sham patients crossed over to ranibizumab 0.5 mg monthly. After 36 months in the core studies, patients in the OLE (n = 500) could receive ranibizumab 0.5 mg PRN based on predefined DME re-treatment criteria. Diabetic retinopathy severity was evaluated photographically using the Early Treatment Diabetic Retinopathy Study DR severity scale. MAIN OUTCOME MEASURES: Change in DR severity from months 36 to 48 by re-treatment status. RESULTS: Among patients who entered the OLE, 121 of 500 (24%) did not require additional ranibizumab injections. Overall, 367 patients had evaluable DR at months 36 and 48. Among patients not requiring ranibizumab re-treatment from months 36 to 48 (88/367), 57% to 78%, 0% to 7%, and 22% to 36% experienced DR severity stability, 2-step or more improvement, and 2-step or more worsening, respectively. Among patients requiring ranibizumab re-treatment (279/367), 84% to 94%, 2%, and 3% to 14% experienced DR severity stability, 2-step or more improvement, and 2-step or more worsening, respectively. On average, vision improvements were maintained during the OLE regardless of change in DR severity. CONCLUSIONS: Diabetic retinopathy severity improvements with ranibizumab were maintained in over 70% of OLE patients after switching from ranibizumab monthly to an individualized ranibizumab 0.5 mg PRN dosing regimen. Because approximately one third of OLE patients experienced DR worsening, careful monitoring should be part of the long-term management of patients with DR.

Visual and Anatomic Outcomes in Patients with Diabetic Macular Edema with Limited Initial Anatomic Response to Ranibizumab in RIDE and RISE.

PURPOSE: To explore the visual acuity and anatomic outcomes over 24 months of patients with diabetic macular edema (DME) who showed a delayed anatomic response after 3 ranibizumab injections in the RIDE and RISE trials. DESIGN: Analysis of data from RIDE and RISE, 2 phase III, parallel, randomized, multicenter, double-masked trials (ClinicalTrials.gov identifiers, NCT00473382 and NCT00473330). PARTICIPANTS: Patients with DME (n = 681) who received monthly intravitreal ranibizumab 0.3-mg injections, ranibizumab 0.5-mg injections, or sham injections. METHODS: Patients were separated into 3 groups: delayed responders (ranibizumab-treated patients with ≤10% central foveal thickness [CFT] reduction after 3 injections), immediate responders (ranibizumab-treated patients with >10% CFT reduction after 3 injections), and sham recipients. Central foveal thickness was measured by time-domain optical coherence tomography, best-corrected visual acuity (BCVA) was measured by Early Treatment Diabetic Retinopathy Study (ETDRS) letter scores, and diabetic retinopathy (DR) was measured by the standardized ETDRS severity scale (using fundus photographs). MAIN OUTCOME MEASURES: Month-24 CFT, BCVA, and DR severity levels. RESULTS: In RIDE and RISE, 9% to 10% of ranibizumab-treated eyes were delayed responders. At month 24, delayed responders had less CFT reduction (median, -102 µm) from baseline compared with immediate responders (median, -274 µm; P < 0.0001). Delayed responders gained a median of 10 letters at 24 months, similar to immediate responders (14 letters; P = 0.15). At month 24, DR improvement among the delayed responders (31% and 22% of patients with ≥2- or ≥3-step DR improvement, respectively) was comparable with that among immediate responders (42% and 17%, respectively; P = 0.21 and P = 0.48, respectively). CONCLUSIONS: With continued treatment, at month 24, patients with DME with delayed anatomic response (≤10% CFT reduction) after 3 ranibizumab injections had visual acuity gains and DR improvement similar to those of patients with DME who had immediate anatomic response.

Influence of Glycosylated Hemoglobin on the Efficacy of Ranibizumab for Diabetic Macular Edema: A Post Hoc Analysis of the RIDE/RISE Trials.

PURPOSE: To investigate the influence of glycosylated hemoglobin (HbA1c) on treatment outcomes in patients with diabetic macular edema (DME) receiving intravitreal ranibizumab. DESIGN: Post hoc analysis of 2 identical phase III clinical trials assessing the efficacy and safety of intravitreal ranibizumab in DME over 36 months (RIDE: NCT00473382/RISE: NCT00473330). PARTICIPANTS: A total of 483 adults with vision loss from DME treated with ranibizumab were included in this analysis from RIDE/RISE. Participants received monthly intravitreal ranibizumab (0.3 or 0.5 mg). MAIN OUTCOME MEASURES: Differences in visual and anatomic outcomes, and diabetic retinopathy (DR) severity score, between subgroups of patients with baseline HbA1c ≤7% versus HbA1c >7% at 36 months. RESULTS: There were 195 patients in RIDE/RISE who were treated with ranibizumab with a baseline HbA1c ≤7% and 288 patients with a baseline HbA1c >7% included in this analysis. The mean improvement in visual acuity (VA) at 36 months was +13 Early Treatment Diabetic Retinopathy Study (ETDRS) letters in patients with baseline HbA1c ≤7% compared with +11 ETDRS letters in the patients with a baseline HbA1c >7% (P = 0.17). After adjustment for baseline central foveal thickness (CFT) and duration of diabetes, the mean CFT reduction was -268 µm in patients with a baseline HbA1c ≤7% and -269 µm in patients with a baseline HbA1c >7% (P = 0.98; 95% confidence interval, -22.93 to 23.54). The proportion of patients with a ≥2-step improvement in DR severity score was 38% in patients with baseline HbA1c ≤7% compared with 41% in the patients with a baseline HbA1c >7% (P = 0.53). There was no correlation of baseline HbA1c with any visual or anatomic parameter. CONCLUSIONS: The improvement in VA, anatomic reduction of macular edema, and improvement in DR severity score with ranibizumab treatment seem to be independent of baseline HbA1c.

Custody plans among parents living with human immunodeficiency virus infection.

OBJECTIVES: To describe and to examine predictors of making custody plans by parents living with the human immunodeficiency virus (HIV) infection. INTERVENTIONS: The custody plans of 296 parents living with HIV for 708 children were examined over 5 years, with at least 85% reassessed annually. RESULTS: Over time, increasing numbers of parents living with HIV made custody plans for all of their children (23.8%-52.8%), typically with extended family members. However, parents change plans frequently, and 44.8% of parents living with HIV died without custody plans. Custody planning was less likely in families with only adolescent children, when parents had a partner, or when parents were depressed. Parents' disclosure of HIV status, physical health status, substance use, and ethnicity were unrelated to making custody plans. CONCLUSION: Custody planning is a slow and unstable process in families affected by HIV.
