Abstract Background Facial angiofibromas (FAs) are a major feature of tuberous sclerosis complex (TSC). Topical rapamycin can successfully treat FAs. A new stabilized cream formulation that protects rapamycin from oxidation has been developed in 0.5% and 1% concentrations. Objectives To assess the efficacy and safety of a novel, stabilized topical rapamycin cream formulation. Methods This multicentre double-blind randomized placebo-controlled dose–response phase II/III study with a parallel design included participants aged 6–65 years with FAs of mild or moderate severity according to the Investigator’s Global Assessment (IGA) scale. Participants were randomized to one of three treatment arms: topical rapamycin 0.5%, topical rapamycin 1% or placebo. Treatment was applied once daily for 26 weeks. Safety and efficacy measures were assessed at days 14, 56, 98, 140 and 182. The primary endpoint was the percentage of participants achieving IGA scores of ‘clear’ or ‘almost clear’ after 26 weeks of treatment. Secondary measures included Facial Angiofibroma Severity Index (FASI) and participant- and clinician-reported percentage-based improvement. Safety measures included the incidence of treatment-emergent adverse events and blood rapamycin concentration changes over time. Results Participants (n = 107) were randomized to receive either rapamycin 1% (n = 33), rapamycin 0.5% (n = 36) or placebo (n = 38). All treated participants were included in the final analysis. The percentage of participants with a two-grade IGA improvement was greater in the rapamycin 0.5% treatment group (11%) and rapamycin 1% group (9%) than in the placebo group (5%). However, this was not statistically significant [rapamycin 0.5%: odds ratio (OR) 1.71, 95% confidence interval (CI) 0.36–8.18 (P = 0.50); rapamycin 1%: OR 1.68, 95% CI 0.33–8.40 (P = 0.53)]. There was a statistically significant difference in the proportion of participants treated with rapamycin cream that achieved at least a one-grade improvement in IGA [rapamycin 0.5%: 56% (OR 4.73, 95% CI 1.59–14.10; P = 0.005); rapamycin 1%: 61% (OR 5.14, 95% CI 1.70–15.57; P = 0.004); placebo: 24%]. Skin adverse reactions were more common in patients following rapamycin application (64%) vs. placebo (29%). Conclusions Both rapamycin cream formulations (0.5% and 1%) were well tolerated, and either strength could lead to clinical benefit in the treatment of FA.

In 2023, the NCCN Guidelines for Hepatobiliary Cancers were divided into 2 separate guidelines: Hepatocellular Carcinoma and Biliary Tract Cancers. The NCCN Guidelines for Biliary Tract Cancers provide recommendations for the evaluation and comprehensive care of patients with gallbladder cancer, intrahepatic cholangiocarcinoma, and extrahepatic cholangiocarcinoma. The multidisciplinary panel of experts meets at least on an annual basis to review requests from internal and external entities as well as to evaluate new data on current and emerging therapies. These Guidelines Insights focus on some of the recent updates to the NCCN Guidelines for Biliary Tract Cancers as well as the newly published section on principles of molecular testing.

AbstractBackground. The field of implementation research has recently seen considerable, and long overdue, interest in equity, with a strong emphasis on recognizing and responding to disparities in care. The COMPLETE (COMPLEx inTErventions and service innovation)framework is intended to support inclusive intervention and service design. The aim is the development of a patient-centered and justice-informed framework for the design of complex healthcare interventions and innovations in service design.Methods. We undertook three studies. (1) We operationalized constructs from sociological theories of inequality, implementation processes, social roles and expectations, to build a Matrix Model of mechanisms that drive the embedding of disparities in complex healthcare interventions and service innovations. (2) We developed patient-centered and justice-informed principles for design that form a Theory of Change that can be applied in intervention and service design. (3) We then linked the Matrix Model and the Theory of Change together with core elements of theories of prefigurative design and research justice, to build a Transformational Design Cycle for complex interventions and service innovations around a set of critical questions about the implications.Results. The COMPLETE framework focuses on the ways health inequalities and inequities are brought into being by systemic mechanisms within health services; are then propagated and normalized through implementation mechanisms; and are then realized and normalized in practice through institutionalized expectations of patients and caregivers. The framework provides tools to resist the naturalization of inequities and inequalities.Conclusion. We developed a framework for intervention and service design that consists of three components: a conceptual model of the translation of social determinants of health through organizational mechanisms that shape patient and caregivers’ lived experience of disparities in health and healthcare; a transformational theory of change; and a set of principles for design that seeks to place restitution for disparities at its center.

Background Obstructive sleep apnea (OSA) is common in heart failure with preserved ejection fraction (HFpEF). However, current evidence is equivocal regarding the potential benefits of treating OSA with positive airway pressure (PAP) therapy in HFpEF. This study assessed the association between adherence to PAP therapy and health care resource use in patients with OSA and HFpEF. Methods and Results Administrative insurance claims data linked with objective PAP therapy usage data from patients with OSA and HFpEF were used to determine associations between PAP adherence and a composite outcome including hospitalizations and emergency room visits. One‐year PAP adherence was based on an adapted US Medicare definition. Propensity score methods were used to create groups with similar characteristics across PAP adherence levels. The study cohort included 4237 patients (54.0% female, mean age 64.1 years); 40% were considered adherent to PAP therapy (30% intermediate adherent, 30% nonadherent). In the matched cohort, PAP‐adherent patients had fewer health care resource use visits than nonadherent patients, a 57% decrease in hospitalizations, and a 36% decrease in emergency room visits versus the year before PAP initiation. Total health care costs were lower in adherent patients than nonadherent patients ($12 732 versus $15 610, P <0.001). Outcomes for intermediately adherent patients were most similar to those for nonadherent patients. Conclusions Treating OSA with PAP therapy in patients with HFpEF was associated with a reduction in health care resource use. These data highlight the importance of managing concomitant OSA in patients with HFpEF, and the need for strategies to enhance PAP adherence in this population.

ImportanceHead and neck cancer–associated lymphedema (HNCaL) affects up to 90% of survivors of head and neck cancer and is a substantial contributor to disability following head and neck cancer treatment. Despite the prevalence and morbidity associated with HNCaL, rehabilitation interventions are not well studied.ObjectiveTo identify and appraise the current evidence for rehabilitation interventions in HNCaL.Evidence ReviewFive electronic databases were searched systematically from inception to January 3, 2023, for studies on HNCaL rehabilitation interventions. Study screening, data extraction, quality rating, and risk of bias assessment were performed by 2 independent reviewers.FindingsOf 1642 citations identified, 23 studies (1.4%; n = 2147 patients) were eligible for inclusion. Six studies (26.1%) were randomized clinical trials (RCTs) and 17 (73.9%) were observational studies. Five of the 6 RCTs were published during 2020 to 2022. Most studies had fewer than 50 participants (5 of 6 RCTs; 13 of 17 observational studies). Studies were categorized by intervention type, including standard lymphedema therapy (11 studies [47.8%]) and adjunct therapy (12 studies [52.2%]). Lymphedema therapy interventions included standard complete decongestive therapy (CDT) (2 RCTs, 5 observational studies), modified CDT (3 observational studies), therapy setting (1 RCT, 2 observational studies), adherence (2 observational studies), early manual lymphatic drainage (1 RCT), and inclusion of focused exercise (1 RCT). Adjunct therapy interventions included advanced pneumatic compression devices (APCDs) (1 RCT, 5 observational studies), kinesio taping (1 RCT), photobiomodulation (1 observational study), acupuncture/moxibustion (1 observational study), and sodium selenite (1 RCT, 2 observational studies). Serious adverse events were either not found (9 [39.1%]) or not reported (14 [60.9%]). Low-quality evidence suggested the benefit of standard lymphedema therapy, particularly in the outpatient setting and with at least partial adherence. High-quality evidence was found for adjunct therapy with kinesio taping. Low-quality evidence also suggested that APCDs may be beneficial.Conclusions and RelevanceThe results of this systematic review suggest that rehabilitation interventions for HNCaL, including standard lymphedema therapy with kinesio taping and APCDs, appear to be safe and beneficial. However, more prospective, controlled, and adequately powered studies are needed to clarify the ideal type, timing, duration, and intensity of lymphedema therapy components before treatment guidelines can be established.

Importance Given the burden of chronic liver disease on the health care system, more information on the hepatoprotective association of statins in the general population is needed. Objective To examine whether regular statin use is associated with a reduction in liver disease, particularly hepatocellular carcinoma (HCC) and liver-related deaths, in the general population. Design, Setting, and Participants This cohort study used data from the UK Biobank (UKB) (individuals aged 37-73 years) collected from baseline (2006-2010) to the end of follow-up in May 2021, from the TriNetX cohort (individuals aged 18-90 years) enrolled from baseline (2011-2020) until end of follow-up in September 2022, and from the Penn Medicine Biobank (PMBB) (individuals aged 18-102 years) with ongoing enrollment starting in 2013 to the end of follow-up in December 2020. Individuals were matched using propensity score matching according to the following criteria: age, sex, body mass index, ethnicity, diabetes with or without insulin or biguanide use, hypertension, ischemic heart disease, dyslipidemia, aspirin use, and number of medications taken (UKB only). Data analysis was performed from April 2021 to April 2023. Exposure Regular statin use. Main Outcomes and Measures Primary outcomes were liver disease and HCC development as well as liver-associated death. Results A total of 1 785 491 individuals were evaluated after matching (aged 55 to 61 years on average, up to 56% men, and up to 49% women). A total of 581 cases of liver-associated death, 472 cases of incident HCC, and 98 497 new liver diseases were registered during the follow-up period. Individuals were aged 55-61 years on average, with a slightly higher proportion of men (up to 56%). In UKB individuals (n = 205 057) without previously diagnosed liver disease, statin users (n = 56 109) had a 15% lower hazard ratio (HR) for the association of developing a new liver disease (HR, 0.85; 95% CI, 0.78-0.92; P &amp;lt; .001). In addition, statin users demonstrated a 28% lower HR for the association with liver-related death (HR, 0.72; 95% CI, 0.59-0.88; P = .001) and a 42% lower HR for the development of HCC (HR, 0.58; 95% CI, 0.35-0.96; P = .04). In TriNetX individuals (n = 1 568 794), the HR for the association of HCC was reduced even further for statin users (HR, 0.26; 95% CI, 0.22-0.31; P = .003). The hepatoprotective association of statins was time and dose dependent, with a significant association in PMBB individuals (n = 11 640) for incident liver diseases after 1 year of statin use (HR, 0.76; 95% CI, 0.59-0.98; P = .03). Taking statins was particularly beneficial in men, individuals with diabetes, and individuals with a high Fibrosis-4 index at baseline. Carriers of the heterozygous minor allele of PNPLA3 rs738409 benefited from statin use and had a 69% lower HR for the association with HCC (UKB HR, 0.31; 95% CI, 0.11-0.85; P = .02). Conclusions and Relevance This cohort study indicates substantial preventive associations of statins against liver disease, with an association with duration and dose of intake.

Importance Lensectomy with primary intraocular lens (IOL) implantation is often used in the management of nontraumatic pediatric cataract, but long-term data evaluating the association of age and IOL location with the incidence of complications are limited. Objective To describe the incidence of complications and additional eye surgeries through 5 years following pediatric lensectomy with primary IOL implantation and association with age at surgery and IOL location. Design, Setting, and Participants This prospective cohort study used Pediatric Eye Disease Investigator Group cataract registry data from 61 institution- and community-based practices over 3 years (June 2012 to July 2015). Participants were children younger than 13 years without baseline glaucoma who had primary IOL implantation (345 bilateral and 264 unilateral) for nontraumatic cataract. Data analysis was performed between September 2021 and January 2023. Exposures Lensectomy with primary IOL implantation. Main Outcome and Measures Five-year cumulative incidence of complications by age at surgery (&amp;lt;2 years, 2 to &amp;lt;4 years, 4 to &amp;lt;7 years, and 7 to &amp;lt;13 years) and by IOL location (sulcus vs capsular bag) were estimated using Cox proportional hazards models. Results The cohort included 609 eyes from 491 children (mean [SD] age, 5.6 [3.3] years; 261 [53%] male and 230 [47%] female). Following cataract extraction with primary IOL implantation, a frequent complication was surgery for visual axis opacification (VAO) (cumulative incidence, 32%; 95% CI, 27%-36%). Cumulative incidence was lower with anterior vitrectomy at the time of IOL placement (12%; 95% CI, 8%-16%) vs without (58%; 95% CI, 50%-65%), and the risk of undergoing surgery for VAO was associated with not performing anterior vitrectomy (hazard ratio [HR], 6.19; 95% CI, 3.70-10.34; P &amp;lt; .001). After adjusting for anterior vitrectomy at lens surgery, there were no differences in incidence of surgery for VAO by age at surgery (&amp;lt;2 years, HR, 1.35 [95% CI, 0.63-2.87], 2 to &amp;lt;4 years, HR, 0.86 [95% CI, 0.44-1.68], 4 to &amp;lt;7 years, HR, 1.06 [95% CI, 0.72-1.56]; P = .74) or by capsular bag vs sulcus IOL fixation (HR, 1.22; 95% CI, 0.36-4.17; P = .75). Cumulative incidence of glaucoma plus glaucoma suspect by 5 years was 7% (95% CI, 4%-9%), which did not differ by age after controlling for IOL location and laterality. Conclusions and Relevance In this cohort study, a frequent complication following pediatric lensectomy with primary IOL was surgery for VAO, which was associated with primary anterior vitrectomy not being performed but was not associated with age at surgery or IOL location. The risk of glaucoma development across all ages at surgery suggests a need for long-term monitoring.

Introduction: Obstructive sleep apnea (OSA) is common in heart failure, although the impact of OSA treatment remains unclear. We assessed the association between adherence to positive airway pressure (PAP) therapy and healthcare resource utilization in patients with OSA and heart failure with reduced ejection fraction (HFrEF). Methods: Administrative insurance claims data linked with objective PAP therapy usage data from patients with OSA and HFrEF were used to measure the association of PAP adherence and a composite clinical outcome of hospitalization and emergency room (ER) visits. US Medicare defines PAP compliance as usage of the device for at least 4 hours/night for 70% of nights in a consecutive 30-day period over 90 days. PAP adherent patients met these criteria for all 4 90-day periods, while PAP non-adherent patients did not meet these criteria for any 90-day period over one year. Propensity score methods were used to create well matched groups with differing PAP adherence levels. Results: The study cohort consisted of 3,182 eligible patients (69.9% male, mean age 59.7 years) of whom 39% were considered adherent to PAP therapy (29% intermediate-adherent, 31% non-adherent). In the year after PAP prescription, after propensity score matching, PAP adherent patients had fewer hospital visits than non-adherent patients, driven by a 24% reduction in ER visits for adherent patients (Table 1a). These results remained consistent with inverse probability weighting and furthermore showed there were no statistically significant differences between intermediate-adherent and non-adherent patients for any outcome (Table 1b). Conclusions: Treating OSA with PAP therapy in patients with HFrEF is associated with a reduction in the composite outcome of hospitalization and ER visits, driven primarily by a reduction in ER visits. Consistent adherence to PAP therapy is required to realize these benefits.

Introduction: The prevalence of obstructive sleep apnea (OSA) in heart failure (HF) patients varies from 30 to 50%. The differences in clinical characteristics, healthcare resource utilization (HCRU), and positive airway pressure (PAP) usage between HF with preserved ejection fraction (HFpEF) vs. HF with reduced ejection fraction (HFrEF) in OSA patients are not well known. Objective: To compare clinical characteristics, PAP usage, and HCRU in OSA patients with HFpEF vs HFrEF. Methods: Retrospective cohort study using US administrative claims data linked to objective PAP usage data over one year. HFpEF and HFrEF were identified by ICD-9/10 codes associated with healthcare encounters 1 year before starting PAP therapy. Pearson’s Chi-squared and Wilcoxon rank-sum tests were used as applicable to compare baseline characteristics and PAP usage, and the pre to post-PAP initiation difference in the number of health care encounters. Results: In total, 7,419 patients with HF and OSA were identified, of which 57% had HFpEF. HFpEF patients were majority female (54%) and older than those with HFrEF (64.1 ± 11.52 vs 59.7 ± 11.24 years, p<0.001). HFpEF had a higher overall comorbidity burden, although coronary artery disease, atrial fibrillation, and other arrhythmias were more prevalent in HFrEF. Both prior to and after PAP therapy, HCRU was higher in HFpEF patients compared to HFrEF (Table 2a). There were no differences in PAP usage between HFpEF and HFrEF (3.6 ± 2.9 vs 3.7 ± 3.0 hrs/night, p=0.070) over the first year of PAP therapy. There was a significant reduction in ER visits and all cause hospitalizations after 1 year of PAP therapy initiation, which was similar between groups (Table 2b). Conclusions: Although there were differences in clinical characteristics between HFpEF and HFrEF patients with OSA, and HFpEF is associated with greater HCRU, PAP therapy usage was similar, and both groups experienced a similar reduction in HCRU after the first year of PAP initiation.

Introduction: Heart failure patients with preserved ejection fraction (HFpEF) frequently have co-morbid obstructive sleep apnea (OSA), although the impact of OSA treatment remains unclear in this patient population. We assessed the association between adherence to positive airway pressure (PAP) therapy and healthcare resource utilization in patients with OSA and HFpEF. Methods: Administrative insurance claims data linked with objective PAP therapy usage data from patients with OSA and HFpEF were used to measure the association of PAP adherence and healthcare resource utilization, defined by hospitalizations and emergency room (ER) visits. US Medicare defines PAP compliance as use for at least 4 hours/night for 70% of nights in a consecutive 30-day period over 90 days. PAP adherent patients met this criteria for all 4 90-day periods, while PAP non-adherent patients did not meet this criteria for any 90-day period over one year. Propensity score methods were used to create well matched groups with differing PAP adherence levels. Results: The study cohort consisted of 4,237 eligible patients (54.0% female, mean age 64.1 years), of whom 40% were considered adherent to PAP therapy (30% intermediate-adherent, 30% non-adherent). After propensity score matching on prior year covariates, during the year after PAP prescription, PAP adherent patients had fewer hospital visits than non-adherent patients, with a 57% reduction in hospitalizations and a 36% reduction in ER visits for PAP adherent patients (Table 1a). These results remained consistent with inverse probability weighting, and furthermore showed a significant difference in hospitalizations between intermediate-adherent and non-adherent patients, but no significant difference in ER visits (Table 1b). Conclusions: Treating OSA with PAP therapy in patients with HFpEF is associated with a reduction in hospitalizations and ER visits. Adherence to PAP therapy is required to realize these clinical benefits.
