The dynamics of Staphylococcal infection and their treatment with antibiotics and bacteriophage in the Galleria mellonella model system.

Critical to our understanding of infections and their treatment is the role the innate immune system plays in controlling bacterial pathogens. Nevertheless, many in vivo systems are made or modified such that they do not have an innate immune response. Use of these systems denies the opportunity to examine the synergy between the immune system and antimicrobial agents. In this study we demonstrate that the larva of Galleria mellonella is an effective in vivo model for the study of the population and evolutionary biology of bacterial infections and their treatment. To do this we test three hypotheses concerning the role of the innate immune system during infection. We show: i) sufficiently high densities of bacteria are capable of saturating the innate immune system, ii) bacteriostatic drugs and bacteriophages are as effective as bactericidal antibiotics in preventing mortality and controlling bacterial densities, and iii) minority populations of bacteria resistant to a treating antibiotic will not ascend. Using a highly virulent strain of Staphylococcus aureus and a mathematical computer-simulation model, we further explore how the dynamics of the infection within the short term determine the ultimate infection outcome. We find that excess immune activation in response to high densities of bacteria leads to a strong but short-lived immune response which ultimately results in a high degree of mortality. Overall, our findings illustrate the utility of the G. mellonella model system in conjunction with established in vivo models in studying infectious disease progression and treatment.

Multivisceral transplantation utilizing hepatitis C virus-viremic donors for hepatitis C virus-negative recipients.

The advent of highly effective and well-tolerated direct-acting antiviral therapy has made it more feasible to transplant hepatitis C virus (HCV)-infected organs into HCV-negative recipients. This case report presents the outcomes of 4 patients who underwent multivisceral transplantation from HCV-nucleic acid test (NAT)-viremic donors, with 1 recipient also requiring a kidney transplant. All recipients received posttransplant direct-acting antiviral therapy with sofosbuvir/velpatasvir (SOF/VEL [Epclusa]). By the fourth week of therapy, none of the recipients exhibited detectable viral loads, and all achieved sustained virologic response at 12 weeks. Allograft function for HCV D+/R- recipients remained excellent throughout follow-up. One recipient died from posttransplant lymphoproliferative disorder and another developed end-stage renal disease; both outcomes were ostensibly unrelated to HCV-donor status. The other 2 patients are progressing well without any evidence of allograft rejection.

Investigating the Obesity Paradox in Colorectal Cancer: An Analysis of Prospectively Collected Data in a Diverse Cohort.

BACKGROUND: Prior studies are inconclusive regarding the effect of obesity on mortality in persons with colorectal cancer (CRC). We sought to determine the association of pre-diagnosis body mass index (BMI) trajectories on mortality after CRC diagnosis. METHODS: Utilizing the Multiethnic Cohort, we included adults aged 18-75 between 1 January 1993 and 1 January 2019 with a diagnosis of CRC and at least three available BMIs. The primary exposure, BMI, was subjected to group-based trajectory modeling (GBTM). We evaluated all-cause and CRC-specific mortality, using Cox proportional hazard (PH) models. RESULTS: Of 924 persons, the median age was 60 years, and 54% were female. There was no statistically significant association between pre-cancer BMI trajectory and either all-cause or cancer-specific mortality. In competing risk analysis, the risk of CRC-specific mortality was higher for African Americans (HR = 1.56, 95% CI [1.00-2.43], p = 0.048) and smokers (HR = 1.59, 95% CI [1.10-2.32], p = 0.015). Risk of all-cause mortality was higher for Hawaiian persons (HR = 2.85, 95% CI [1.31-6.21], p = 0.009) and persons with diabetes (HR = 1.83, 95% CI [1.08-3.10], p = 0.026). CONCLUSIONS: Pre-diagnosis BMI trajectories were not associated with mortality after CRC diagnosis, whereas race/ethnicity, diabetes, and smoking were associated with an increased risk of death. Our findings suggest the obesity paradox alone does not account for mortality after CRC diagnosis.

Real-World Experience Using a Multi-Modality System using Intense Pulsed Light, Radiofrequency Microneedling, High-Intensity Focused Ultrasound, or Thermal Radiofrequency, 808, HIFU for Skin Rejuvenation Treatment.

BACKGROUND: Medical aesthetic procedures for facial rejuvenation with laser and energy-based devices (EBDs) are rapidly increasing. The following cases highlight real-life experience using a multi-modality system with various handpieces that combine intense pulsed light (IPL), laser hair removal (808 diode), high-intensity focused ultrasound (HIFU), radiofrequency microneedling (RFM), and thermal radiofrequency (RF) for antiaging and rejuvenation treatment. Laser and RFM treatments may improve skin conditions by inducing cutaneous changes that remodel the skin matrix. METHODS: Six physicians who treat patients for skin rejuvenation reported on clinical cases from their practice using a multi-modality system with various handpieces. RESULTS: During the meeting, the advisors discussed 15 cases and agreed to select seven patients with different ages and skin phototypes receiving various treatments for photodamage of the face, neck, and décolleté. The advisors discussed why they selected the case, previous treatment, type of treatment, results, and clinical pearls. CONCLUSION: Sharing best practices in medical aesthetics using combination treatments on a single multi-modality energy-based device such as laser and MRF for facial, neck, and chest skin may support healthcare providers treating patients for skin rejuvenation to improve clinical outcomes.

Real-World Clinical Experience With an Allograft Adipose Matrix for Replacing Volume Loss in Face, Hands, and Body.

INTRODUCTION: Real-world experience using an allograft adipose matrix (AAM) (Renuva) is presented as a series of seven cases demonstrating successful use of the matrix by nine expert cosmetic physicians across the United States. AAM is donated tissue that is aseptically processed without terminal irradiation into a transplantable adipose matrix that functions as a natural, versatile, and nonimmunogenic cushioning and volume-restoring tissue. When injected, the adipose matrix is replaced with the body's own fat cells and provides the cellular scaffold required for volume restoration and retention. METHODS: Nine expert dermatologists were selected to share and discuss real-world patient cases using AAM. The experts discussed a variety of cases and selected 7 cases that demonstrated successful, novel use of AAM to present in this manuscript. RESULTS: Experts agreed that the novel AAM is an easy-to-use, effective, and safe alternative to traditional fillers and fat grafting. CONCLUSION: The use of the AAM is recommended for the face, hands, and other adipose tissue-containing parts of the body. The presented real-world cases provide guidance on how to identify ideal candidates to ensure optimal volume restoration results.

Food-Related Quality of Life Is Impaired in Latinx and Non-Latinx Patients With Inflammatory Bowel Disease.

Background and Aims: Anxiety over food choices and symptoms related to food consumption diminish quality of life (QoL) in inflammatory bowel disease (IBD) patients. However, the specific factors that impact QoL among IBD patients remain unclear. In this study, we analyzed the relationships of demographic and disease factors with food-related QoL (FRQoL) in a large, diverse US cohort of IBD patients. Methods: In this cross-sectional analysis of 1108 IBD patients aged ≥18 years, we measured FRQoL with the 29-item Food-Related Quality of Life Questionnaire (FR-QoL-29) and disease activity with the Harvey-Bradshaw index in Crohn's disease (CD) patients or the Simple Clinical Colitis Activity Index in ulcerative colitis (UC) patients. Latinx immigrants completed a Spanish translation of the FR-QoL-29. A subset of patients had colonoscopy and inflammatory marker data available. We used univariate, multivariate, and subgroup analyses to examine the factors that influence FRQoL. Results: In our cohort, 55% of IBD patients self-identified as Latinx. Latinx and non-Latinx patients had similar FR-QoL-29 scores. Female patients had significantly lower FRQoL than male patients (P = .001). Increasing age and IBD duration correlated with higher FRQoL (P < .0001). In UC patients, higher Simple Clinical Colitis Activity Index scores (P < .0001), higher Mayo scores (P = .0009), and longer disease duration (P = .03) predicted significantly lower FRQoL. Disease activity and FRQoL were not significantly related in CD patients. Conclusion: This is the largest study to date to examine FRQoL in American IBD patients, and the first to include Latinx patients. Disease-related factors had a greater impact on FRQoL than ethnicity. Clinical and endoscopic disease activity had a more detrimental impact on FRQoL in UC than in CD. Diet intervention studies are needed to alleviate symptoms and improve FRQoL in the IBD population.

Racial disparities in access to liver transplantation in patients with early-stage hepatocellular carcinoma.

BACKGROUND: Orthotopic liver transplantation is the recommended treatment option for patients with early-stage hepatocellular carcinoma and concomitant cirrhosis. Waitlist candidacy can be affected by social determinants of health that vary across races and ethnicities. Our study sought to evaluate whether racial/ethnic disparities exist in access to orthotopic liver transplantation in patients with hepatocellular carcinoma. METHODS: The National Cancer Database participant use file was used to analyze data between 2004 and 2020. Patients 18-70 years of age with TNM clinical stage I and II hepatocellular carcinoma who received either orthotopic liver transplantation or liver directed/nonsurgical therapies were included. Baseline demographic variables and treatment modalities were collected. Patients were assigned fixed categories on the basis of race and ethnicity. Descriptive statistics, multivariable logistical regressions, effects modification analysis, and propensity matching were used. RESULTS: There were 23,313 non-Hispanic White, 5,215 non-Hispanic Black, 5,581 Hispanic, and 2,768 other patients included in this analysis. Significant socioeconomic variation was observed across races. Non-Hispanic White patients were more likely to undergo orthotopic liver transplantation than non-Hispanic Black patients. The proportion of patients insured by Medicare was the same between non-Hispanic White and non-Hispanic Black patients. There was a graeter proportion of non-Hispanic Black patients with Medicaid compared with non-Hispanic White patients, whereas a lower proportion of non-Hispanic Black patients were insured via private insurance compared with non-Hispanic White patients. Effect modification analysis showed the non-Hispanic Black patients were less likely to undergo orthotopic liver transplantation for those with private and Medicare coverage compared with non-Hispanic White patients. Propensity matching showed a significantly decreased rate of orthotopic liver transplantation in non-Hispanic Black patients compared with non-Hispanic White patients. CONCLUSION: Non-Hispanic Black patients were less likely to undergo orthotopic liver transplantation for early-stage hepatocellular carcinoma, despite adjusting for cancer stage and socioeconomic factors, compared with non-Hispanic White patients. Social determinants of health were associated with the probability of undergoing orthotopic liver transplantation. Understanding disparities related to social determinants of health will help guide health policy changes and improved access to care.

Immunosuppression regimen and latitude impact keratinocyte carcinoma risk in U.S. liver transplant recipients.

Immunosuppression after solid organ transplantation is associated with an increased risk of keratinocyte carcinoma (KC). Despite its established morbidity, KC risk in liver transplant (LT) recipients is understudied, including the contribution of immunosuppression regimen and latitude. A retrospective cohort of 9,966 adult first LT alone recipients alive with their native allograft at 1-year post-LT without prior KC between 2007 and 2016 were identified using linked data from the Organ Procurement and Transplantation Network and Medicare administrative claims. The primary exposures were immunosuppression regimen and latitude of residence. The primary outcome was incident, de novo KC occurring at least 1-year after LT. Adjusted Cox regression analysis stratified by transplant center was used in all analyses. The cohort was 63.4% male, 70.2% White and with median age 61 years (interquartile range, IQR, 54-66) at transplant. Calcineurin inhibitor (CNI) with anti-metabolite combination was independently associated with incident KC when measured as intention-to-treat (adjusted hazard ratio (aHR) 1.21 vs. CNI monotherapy, 95% CI 1.02-1.43, p = 0.026), in a time-updating as-treated analysis (aHR 1.61, 95% CI 1.34-1.93; p < 0.001) and when measured as cumulative exposure (aHR 1.13 per 6-month increase, 95% CI: 1.02-1.33; p = 0.027). More southern latitude of residence was also independently associated with incident KC with an aHR of 1.26 per 5°N decrease towards the Equator (95% CI: 1.08-1.47, p = 0.003). We demonstrate independent effects of CNI with antiM immunosuppression regimen and latitude of residence on the risk of post-LT KC, which will better inform screening practices and immunosuppression management.

The impact of energy-based devices on sebum in acne vulgaris: A systematic review.

BACKGROUND: Acne vulgaris (AV) is a widespread inflammatory skin condition associated with increased sebum production, abnormal keratinization, bacterial overgrowth, and inflammation. Overactive sebaceous glands (SGs) produce excess sebum, promote Cutibacterium acnes growth, and affect acne development. Energy-based treatments (EBDs), including light therapy, photodynamic therapy (PDT), lasers, and radiofrequency (RF) devices, have emerged as effective treatment options. As the use of EBDs becomes more widespread, it is imperative to understand their effects on skin parameters, such as sebum, in AV. METHODS: Searches were conducted in Embase, PubMed, Web of Science, and the Cochrane Library. The studies included were randomized and nonrandomized trials on facial AV that used EBDs and featured objective casual sebum level (CSL) measurements via Sebumeter. Data synthesis involved percentage reductions in CSL at follow-ups compared to baseline. RESULTS: Twenty-three studies were analyzed. PDT and RF consistently reduced CSL by 30%-40% and 30%-35%, respectively. Laser therapy showed lesser reductions, whereas light therapy varied significantly and studies had a high risk of bias. All EBD therapies were more effective than no treatment and PDT was superior to light monotherapy. Laser therapy combined with fractional microneedling radiofrequency (FMR) or as a standalone was more effective than laser alone. CONCLUSION: Noninvasive sebum measurement provides valuable insights into AV treatment efficacy. PDT, lasers, especially the 1450-nm diode laser, and FMR are promising for reducing sebum. Standardization of measurement techniques and further research are vital for enhancing treatment personalization, reducing side effects, and improving AV management.

Hospital readmission for acute kidney injury is independently associated with de novo end-stage renal disease after liver transplantation.

End-stage renal disease (ESRD) after liver transplantation (LT) is associated with high morbidity and mortality. The consequences of hospitalizations for post-LT acute kidney injury (AKI) are poorly understood. Using linked Medicare claims and transplant registry data, we analyzed adult liver alone recipients not receiving pre-transplant dialysis between 1/1/2007-12/31/2016. Covariate-adjusted Cox proportional hazards models stratified by center evaluated factors associated with AKI readmission during the first post-LT year, and whether AKI readmission was associated with de novo early (<1 y) or late (≥1 y) ESRD post-LT. The cohort included 10,559 patients and was 64.5% male, 72.5% White, 8.1% Black and 14.0% Hispanic with median age 62 years. Overall, 2,875 (27.2%) patients had ≥1 AKI hospitalization during the first year. eGFR at LT was associated with AKI readmission (aHR 1.16 per 10 mL/min/1.73m2 decrease; p<0.001). The aHR for early ESRD in patients with ≥1 AKI readmission <90 days post-LT was 1.90 (p<0.001). The aHRs for late ESRD with 1 and ≥2 prior AKI readmissions were 1.57 and 2.80 respectively (p<0.001). AKI readmissions in the first post-LT year impact over one-quarter of recipients. These increase the risk of subsequent ESRD, but may represent an opportunity to intervene and mitigate further renal dysfunction.

Artificial intelligence in cosmetic dermatology.

BACKGROUND: Cosmetic dermatology is a growing field as more patients are seeking treatments for esthetic concerns. Traditionally, practitioners and patients utilize their own perceptions, current beauty standards, and manual observation to determine their satisfaction with cosmetic interventions. Artificial intelligence (AI) can be introduced into cosmetic dermatology to provide objective data-driven recommendations to both dermatologists and patients. OBJECTIVE: The purpose of this paper is to compose a unified review that illustrates the various facets of artificial intelligence and formulate a hypothesis regarding the new implications of artificial intelligence in cosmetic dermatology specifically. METHODS: A comprehensive search on PubMed was conducted to identify the available information related to AI in cosmetic dermatology. The search was conducted using a combination of keywords including "cosmetic dermatology" and "artificial intelligence." RESULTS: The current literature indicates that AI models offer personalized, efficient, and result-driven outputs that can enhance cosmetic outcomes, patient satisfaction, and overall experience. CONCLUSION: Artificial intelligence integration in cosmetic dermatology shows a promising future, offering the ability to analyze vast data sets and deliver a tailored patient experience. By incorporating AI into cosmetic dermatology, there is an opportunity to balance evidence-based decision-making with the artistic human touch of cosmetic dermatologists.

Variation in intention-to-treat survival by MELD subtypes: All models created for end-stage liver disease are not equal.

BACKGROUND & AIMS: Kidney dysfunction is a major determinant of prognosis in patients with decompensated cirrhosis awaiting transplantation. We hypothesized that for identical model for end-stage liver disease (MELD) scores at listing, outcomes before and after liver transplantation may vary if the predominant driver of the MELD score is serum creatinine (Cr) vs. serum bilirubin (Br) or international normalized ratio (INR). METHODS: We evaluated all adult patients registered for liver transplantation (LT) between 2016-2020 and excluded patients receiving MELD exceptions or undergoing dual organ transplantation. Using K-Means clustering analysis, we classified each patient as MELD-Br, MELD-INR or MELD-Cr depending on the dominant variable for their MELD score. The primary outcome was intent-to-treat (ITT) survival, defined as survival within 1 year from listing with or without LT. RESULTS: MELD scores of LT waitlist registrants were clustered into three subtypes: MELD-Br (n = 13,658), MELD-INR (n = 13,809), and MELD-Cr (n = 12,412). One-year ITT survival rates were 78% (MELD-Br), 75% (MELD-INR), and 65% (MELD-Cr), p <0.01. ITT survival was lower for each MELD subtype for females compared to males (e.g. MELD-Cr: 63% females vs. 67% males, p <0.0001). The MELD-Cr subtype had the highest MELD at listing (MELD-Cr 23.4 vs. MELD-Br 19.2 vs. MELD-INR 21.0) and the largest decline in MELD over 3 months (23% vs. 12% vs. 21%). In adjusted analyses including MELD-Na, MELD-Cr was associated with higher waitlist mortality (hazard ratio 1.339, 95% CI 1.279-1.402) and lower LT rates (hazard ratio 0.688, 95% CI 0.664-0.713) compaed to the other subtypes. CONCLUSIONS: For equivalent listing practices, registrants with the MELD-Cr subtype have lower ITT survival. MELD subtype may serve as a more sophisticated variable for dynamic assessment of mortality risk and to guide organ allocation. IMPACT AND IMPLICATIONS: The model for end-stage liver disease (MELD) score is an excellent predictor of waitlist mortality; however, our work highlights that the driver of a patient's MELD score matters and particularly those driven by elevated creatinine are associated with lower 1-year intent-to-treat survival. The 1-year intent-to-treat survival is also lower for women compared to men within the Cr-dominant subtype. These results are important for physicians and patients undergoing LT evaluation as creatinine may serve as a marker of prognosis and even if creatinine levels improve the prognosis remains poor, necessitating discussion about alternative pathways for transplant. Our work also highlights that the type of kidney injury matters, in that those with acute kidney injury were more likely to die or remain on the waitlist than those with chronic kidney disease within the creatinine-dominant subtype.

Improvement in Survival After Transplantation for Critically Ill Patients With Cirrhosis in the United States.

INTRODUCTION: There is considerable debate over the indication of liver transplantation (LT) for critically ill patients with cirrhosis, in part due to their potentially poor post-LT prognosis. We analyzed the epidemiology and outcome of LT for critically ill patients with cirrhosis over 4 time periods of 4 years. METHODS: We included adult patients who underwent liver transplant alone between 2005 and 2020 using the United Network for Organ Sharing registry database. We defined critically ill patients with cirrhosis as being in the intensive care unit with 1 or more of the following characteristics at the time of LT: (i) grade III/IV hepatic encephalopathy, (ii) mechanical ventilation, (iii) dialysis, and (iv) vasopressors. RESULTS: A total of 85,594 LT recipients were included, 5,827 (6.8%) of whom were classified as being critically ill with cirrhosis at the time of LT. The number and percentage of critically ill LT recipients with cirrhosis increased over the study period: 819 (4.3%) in 2005-2008 vs 2,067 (7.9%) in 2017-2020, P < 0.001. There was a 17% absolute increase in 1-year survival after LT: 72.5% in 2005-2008 vs 89.5% in 2017-2020, P < 0.001. The 1-year post-LT survival gap between critically ill and noncritically ill patients with cirrhosis narrowed over the study period: 16.7 percentage points in 2005-2008 vs 4.6 percentage points in 2017-2020. The year of LT was independently associated with lower 1-year post-LT mortality (hazard ratio 0.92, 95% confidence interval 0.91-0.93, P < 0.001). DISCUSSION: The absolute number and relative percentage of LT recipients who were critically ill increased over time, as did 1-year post-LT survival. Meanwhile, the gap in survival between this group of patients and noncritically ill patients with cirrhosis decreased but persisted. Cautious access to selected LT candidates who are critically ill may be warranted, provided the gap in survival with noncritically ill patients remains as small as possible.

The Liver Cirrhosis Network Cohort Study: Cirrhosis Definition, Study Population, and Endpoints.

INTRODUCTION: One of the primary goals of the Liver Cirrhosis Network (LCN) is to develop a cohort study to better understand and predict the risk of hepatic decompensation and other clinical and patient-reported outcomes among patients with Child A cirrhosis. METHODS: The LCN consists of a Scientific Data Coordinating Center and 10 clinical centers whose investigators populate multiple committees. The LCN Definitions and Measurements Committee developed preliminary definitions of cirrhosis and its complications by literature review, expert opinion, and reviewing definition documents developed by other organizations. The Cohort Committee developed the study protocol with the input of the steering committee. RESULTS: The LCN developed a prospective cohort study to describe and predict the rates of incident clinical events pertaining to first decompensation and patient-reported outcomes. The LCN developed a pragmatic definition of compensated cirrhosis incorporating clinical, laboratory, imaging, and histological criteria. Definitions of incident and recompensated ascites, overt hepatic encephalopathy, variceal hemorrhage, bleeding because of portal gastropathy, and hepatocellular carcinoma were also codified. DISCUSSION: The LCN Cohort Study design will inform the natural history of cirrhosis in contemporary patients with compensated cirrhosis. The LCN Definitions and Measures Committee developed criteria for the definition of cirrhosis to standardize entry into this multicenter cohort study and standardized criteria for liver-related outcome measures. This effort has produced definitions intended to be both sensitive and specific as well as easily operationalized by study staff such that outcomes critical to the LCN cohort are identified and reported in an accurate and generalizable fashion. REGISTRATION: NCT05740358.

Use of HBsAg-positive donors in liver transplantation: An ILTS-EASL-AASLD multisociety survey.

The gap between organ supply and demand in liver transplantation remains large in most parts of the world. One strategy to increase the donor pool is to use grafts infected with HCV, HBV, and/or HIV viruses. We aimed to explore the current use of HBsAg-positive liver grafts worldwide. A prospective cross-sectional web-based survey was designed, with a total of 28 queries, assessing national and local regulations, center experience, and center-specific experience related to the topic, and sent to all members of International Liver Transplantation Society, European Association for the Study of the Liver, and American Association for the Study of the Liver, and promoted on social media. A total of 135 liver transplant centers answered the survey: 38% from WHO European Regions, 39% from American regions, and 9.7% from South-East Asian regions. Most of the participating centers (67.3%) had been performing liver transplantation for over 15 years, with a mean of 66.5 liver transplants per year, and 54% also performed living-donor liver transplants. HBV-related disease was the indication for liver transplantation in an average of 15% of all liver transplantation cases. Regarding national and/or regional regulations, 40% of the centers reported that the use of HBsAg-positive donors was permitted, and an additional 20% could use them under special circumstances. Thirty-two centers (31%) had previously used HBsAg-positive donors. Among these centers, 62.5% conducted living-donor liver transplants and showed an increased inclination toward the use of HBsAg-positive grafts in centers with elevated waitlist mortality. HBsAg-positive donors are underutilized worldwide. The use of HBsAg-positive liver grafts could help to increase the donor pool, particularly in highly endemic areas.

Care of Diabetes and the Sacrifice of Evidence-Based Medicine and Health Equity.

The American Diabetes Association and the European Association for the Study of Diabetes published a 2022 consensus report recommending changes in diabetes care. This Perspective raises three concerns: with how the report summarizes evidence, how it frames the social determinants of health (SDOH), and with its transnational composition and conflicts of interest. The Perspective analyzes three new clinical recommendations that change the role of metformin from first-line therapy to a first-line option, for the inclusion of weight management as a co-primary treatment goal with glycemic control for patients without cardiac or renal complications, and for addition of the SDOH as a universal component of diabetes care together with lifestyle changes and self-management support. The Perspective considers how the poor evidence assessments of the recommendations and the imprecise framing of the SDOH introduce bias. The composition of the panel's membership poorly represents and accounts for the challenges faced by vulnerable US communities or safety net providers. The report is placed in a historical context for diabetes of organized medicine's failures to overcome prejudices and promote health equity. The Perspective concludes that the report perpetuates a pattern of prejudice within organized medicine at the expense of scientific precision and health equity.

Real-world evidence for factors associated with maintenance treatment practices among US adults with autoimmune hepatitis.

BACKGROUND AND AIMS: While avoidance of long-term corticosteroids is a common objective in the management of autoimmune hepatitis (AIH), prolonged immunosuppression is usually required to prevent disease progression. This study investigates the patient and provider factors associated with treatment patterns in US patients with AIH. APPROACH AND RESULTS: A retrospective cohort of adults with the incident and prevalent AIH was identified from Optum's deidentified Clinformatics Data Mart Database. All patients were followed for at least 2 years, with exposures assessed during the first year and treatment patterns during the second. Patient and provider factors associated with corticosteroid-sparing monotherapy and cumulative prednisone use were identified using multivariable logistic and linear regression, respectively.The cohort was 81.2% female, 66.3% White, 11.3% Black, 11.2% Hispanic, and with a median age of 61 years. Among 2203 patients with ≥1 AIH prescription fill, 83.1% received a single regimen for >6 months of the observation year, which included 52.2% azathioprine monotherapy, 16.9% azathioprine/prednisone, and 13.3% prednisone monotherapy. Budesonide use was uncommon (2.1% combination and 1.9% monotherapy). Hispanic ethnicity (aOR: 0.56; p = 0.006), cirrhosis (aOR: 0.73; p = 0.019), osteoporosis (aOR: 0.54; p =0.001), and top quintile of provider AIH experience (aOR: 0.66; p = 0.005) were independently associated with lower use of corticosteroid-sparing monotherapy. Cumulative prednisone use was greater with diabetes (+441 mg/y; p = 0.004), osteoporosis (+749 mg/y; p < 0.001), and highly experienced providers (+556 mg/y; p < 0.001). CONCLUSIONS: Long-term prednisone therapy remains common and unexpectedly higher among patients with comorbidities potentially aggravated by corticosteroids. The greater use of corticosteroid-based therapy with highly experienced providers may reflect more treatment-refractory disease.

Real-world experience with a treatment with a skincare regimen of products containing the Macrocystis pyrifera ferment for optimizing facial skin rejuvenation.

BACKGROUND: Specialized aesthetic skincare treatments are an important part of helping reduce facial signs of aging. AIMS: This article highlights real-world experience with a Macrocystis pyrifera ferment-containing skincare regimen comprising a cleansing foam, a serum, and a moisturizer with anti-aging, anti-inflammatory, anti-erythema, and healing properties for facial skin condition improvement. PATIENTS/METHODS: The real-world case (RWC) series presented highlights and the expert panel's clinical experience with the M. pyrifera ferment-containing skincare regimen used for 12 weeks to improve facial skin conditions. The panelists convened a meeting to discuss and select RWCs from their practice using the M. pyrifera ferment-containing skincare regimen. RESULTS: The RWC series showed that erythema and inflamed, easily irritated skin bother patients, even when it is mild. Reducing inflammation, erythema, and visible signs of facial aging and improving skin health contributed to patient satisfaction. CONCLUSION: The M. pyrifera ferment-containing skincare regimen comprising a cleansing foam, a serum, and a moisturizer is effective in decreasing the visible effects of inflammation and signs of aging while promoting healing by enhancing barrier resilience and recovery.

Hospitalizations for opportunistic infections following transplantation and associated risk factors: A national cohort study of Medicare beneficiaries.

BACKGROUND: Opportunistic infections (OIs) are a significant cause of morbidity and mortality after organ transplantation, though data in the liver transplant (LT) population are limited. METHODS: We performed a retrospective cohort study of LT recipients between January 1, 2007 and Deceber 31, 2016 using Medicare claims data linked to the Organ Procurement and Transplantation Network database. Multivariable Cox regression models evaluated factors independently associated with hospitalizations for early (≤1 year post transplant) and late (>1 year) OIs, with a particular focus on immunosuppression. RESULTS: There were 11 320 LT recipients included in the study, of which 13.2% had at least one OI hospitalization during follow-up. Of the 2638 OI hospitalizations, 61.9% were early post-LT. Cytomegalovirus was the most common OI (45.4% overall), although relative frequency decreased after the first year (25.3%). Neither induction or maintenance immunosuppression were associated with early OI hospitalization (all p > .05). The highest risk of early OI was seen with primary sclerosing cholangitis (aHR 1.74; p = .003 overall). Steroid-based and mechanistic target of rapamycin inhibitor-based immunosuppression at 1 year post LT were independently associated with increased late OI (p < .001 overall). CONCLUSION: This study found OI hospitalizations to be relatively common among LT recipients and frequently occur later than previously reported. Immunosuppression regimen may be an important modifiable risk factor for late OIs.
