RESUMEN

PURPOSE: This cross-sectional prospective study measured utility values of upper eyelid dermatochalasis to quantify its impact on quality of life and assess cost-effectiveness of upper blepharoplasty. METHODS: Utility of dermatochalasis was assessed using the standard reference gamble and time trade-off methods, with dual anchor points of perfect eye function and perfect health. The utility value obtained was used to create a Markov model and run a cost-effectiveness analysis of blepharoplasty as a treatment for dermatochalasis while utilizing the societal perspective. RESULTS: One hundred three patients with dermatochalasis recruited from an urban outpatient ophthalmology clinic completed the utility survey. The authors determined utility values for dermatochalasis ranging from 0.74 to 0.92 depending on the measurement method (standard reference gamble/time trade-off) and anchor points. The cost-effectiveness analysis yielded an incremental cost-effectiveness ratio of $3,146 per quality-adjusted life year, well under the conventional willingness-to-pay threshold of $50,000 per quality-adjusted life year. Probabilistic sensitivity analysis with Monte Carlo simulation demonstrated that blepharoplasty would be cost-effective in 88.1% of cases at this willingness-to-pay threshold. CONCLUSIONS: Dermatochalasis has an impact on quality of life that is significantly associated with level of perceived functional impairment. Rising health care costs have underscored the importance of providing value-based treatment to patients, and the results of this study suggest that blepharoplasty is a cost-effective treatment option for symptomatic bilateral upper eyelid dermatochalasis.

RESUMEN

BACKGROUND AND AIM: Recently, there has been an increased focus on the role nutrition and diet play in maintaining health in inflammatory bowel disease (IBD). We aimed to assess the overall quality, strength, and transparency of conflicts among guidelines on nutrition/diet in IBD. METHODS: A systematic search was performed on multiple databases from inception until January 1, 2021, to identify guidelines pertaining to nutrition or diet in IBD. All guidelines were reviewed for disclosure of conflicts of interest (COI) and funding, recommendation quality and strength, external document review, patient representation, and plans for update-as per Institute of Medicine (IOM) standards. In addition, recommendations and their quality were compared between guidelines/societies.​ RESULTS: Seventeen distinct societies and a total of 228 recommendations were included. Not all guidelines provided recommendations on key aspects of diet-such as the role of supplements or the appropriate micro/macro nutrition in IBD. Fifty-nine percent of guidelines reported on COI, 24% underwent external review, and 41% included patient representation. 18.4%, 25.9%, and 55.7% of recommendations were based on high-, moderate-, and low-quality evidence, respectively. 10.5%, 24.6%, and 64.9% of recommendations were strong, weak/conditional, and did not provide a strength, respectively. The proportion of high-quality evidence (p = 0.12) and strong recommendations (p = 0.83) did not significantly differ across societies. CONCLUSIONS: Many guidelines do not provide recommendations on key aspects of diet/nutrition in IBD. As over 50% of recommendations are based on low-quality evidence, further studies on nutrition/diet in IBD are warranted to improve the overall quality of evidence.

RESUMEN

Telemedicine generally refers to the use of technology to communicate with patients and provide health care from a distance. Advances in technology, specifically computers, cellphones, and other mobile devices, have facilitated healthcare providers' growing ability to virtually monitor and mentor patients. There has been a progressive expansion in the use of telemedicine in the field of gastroenterology (GI), which has been accelerated by the COVID-19 pandemic. In this review, we discuss telemedicine-its history, various forms, and limitations-and its current applications in GI. Specifically, we focus on telemedicine in GI practice in general and specific applications, including the management of inflammatory bowel disease, celiac disease, and colorectal cancer surveillance and its use as an aid in endoscopic procedures.

RESUMEN

Telemedicine refers to the use of information and communication technologies for providing health care at a distance. Through the use of telecommunication technologies such as cell phones, computers, and other electronic devices, health care providers are able to conduct patient visits, mentor/train other providers, and monitor patients' chronic diseases remotely, potentially hundreds or thousands of miles away. Over the past 2 decades, the use of telemedicine has grown in the field of hepatology. In this review, we provide a focused primer on telemedicine and its current applications in hepatology. In particular, we discuss the use of telemedicine in the management of chronic hepatitis C, the complications of liver disease, as well as preliver transplantation evaluation and posttransplantation care. In addition, we provide a synopsis of the effect of the coronavirus disease 2019 (COVID-19) pandemic on the use of telemedicine in hepatology.

RESUMEN

Gastrointestinal endoscopy in patients with advanced liver disease poses various challenges, a major one being procedural sedation and its associated considerations. While sedation during endoscopy can improve patient comfort, decrease anxiety, and facilitate procedural completion, in patients with advanced liver disease, it is also associated with substantial and unique risks due to alterations in drug metabolism and other factors. As such, the choice of sedative agent(s) and related logistics may require careful inter-disciplinary planning and individualized considerations. Furthermore, a large proportion of agents require dose reductions and particular monitoring of the vital signs, level of consciousness, and other indices. In the present review, we provide a contemporary overview of procedural sedation considerations, commonly used intravenous sedatives, and second-line as well as novel sedatives for gastrointestinal endoscopy in patients with advanced liver disease.

RESUMEN

BACKGROUND & AIMS: Primary sclerosing cholangitis (PSC) is an idiopathic, cholestatic liver disease with a diverse range of clinical manifestations. Inter-regional data on PSC are variable, but its global geoepidemiology has not been well-studied. We aimed to examine the worldwide incidence, prevalence and features of PSC and PSC-inflammatory bowel disease (PSC-IBD). METHODS: A systematic search of multiple databases was conducted to identify all original, full-text studies until December 2020 with data regarding the incidence rate (IR) and/or prevalence of PSC. Outcomes were PSC IR, prevalence, features and IBD concurrence. Additionally, a meta-analysis of PSC IR was performed. The study was registered in PROSPERO (CRD42021224550). RESULTS: Of the 1003 studies identified, 17 studies spanning three continents were included. PSC IR was 0.60 per 100 000 person-years (PY) (95% confidence interval: 0.37-0.88 per 100 000 PY). In pooled subgroup analysis for studies conducted in Europe and North America, PSC IR was 0.62 and 0.53 per 100 000 PY, respectively. PSC prevalence ranged 0-31.7 per 100 000 persons, with notable inter-regional differences. Mean age at PSC diagnosis was bimodally distributed, with relative peaks at 15 and 35 years. Mean concurrence of IBD with PSC was 50%, with 76% having ulcerative colitis, 17% Crohn's disease and 8% indeterminate/unspecified IBD. CONCLUSION: While considerable heterogeneity exists in the geoepidemiology of PSC, overall, the classical dogmata of male predilection, bimodal distribution of mean age and high PSC-IBD concurrence appear to hold true. Despite a seemingly stable IR over time, further studies are needed to better understand the geoepidemiology of PSC.

RESUMEN

PURPOSE: Previous studies have suggested that inflammatory bowel disease (IBD) occurs at higher rates among non-Hispanic Whites (NHWs) compared to other ethnicities; however, Hispanics as the largest minority in the United States remain underrepresented in IBD research and we hypothesize that they have similar rates of IBD. We examined the epidemiology, demographics, clinical presentation, and treatment of IBD in a predominantly Hispanic cohort in Los Angeles (LA) County. METHODS: This was a retrospective cohort study based at Olive View-UCLA Medical Center, one of the three major safety-net hospitals in LA County. Electronic medical records from 2015 to 2018 were queried, and biopsy-proven cases of IBD (n = 170) were identified. Outcomes included the incidence and prevalence of IBD, disease distribution, treatment, and IBD-related surgery. RESULTS: The incidence of IBD among Hispanics was 175 (95% confidence interval [CI] 127-240) and 113 (95% CI 62-200) for NHWs per 100,000 person-years. Prevalence of IBD per 100,000 people was 418 (95% CI 341-512) for Hispanics and 557 (95% CI 431-739) for NHWs. Notably, the proportion of Hispanic IBD patients with a history of smoking was 21.5% vs 50.8% in NHWs (p = 0.011). There were no significant differences between the two groups with regard to Montreal classification, pharmacotherapy, or IBD-related surgery. CONCLUSIONS: In one of the largest US studies of Hispanics with IBD, and the only one to have both clinical and histopathologic confirmation as inclusion criteria, we found the incidence and prevalence of IBD among Hispanics to be higher than previously recognized and comparable to NHWs. Additionally, Hispanic IBD patients had lower rates of smoking compared to NHWs.

RESUMEN

BACKGROUND: Gastric signet ring cell carcinoma (GSRC) is a rare but increasingly prevalent tumor histotype whose clinical features and natural history are poorly understood, particularly in the USA and minorities. AIMS: To examine the occurrence, clinico-demographic characteristics, oncologic features, treatment, and outcomes of GSRC in a predominantly minority county hospital setting and benchmark them against data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. METHODS: We queried biopsy-proven GSRC cases at a Los Angeles County hospital, from 2004 to 2017. Clinical characteristics, treatment, and survival data were collected and compared to SEER data. RESULTS: We identified 63 patients with GSRC. Compared to SEER, our cohort was significantly younger (52.6 vs. 63.5 years, p < 0.01), Hispanic/Latino predominant (81% vs. 20%, p < 0.01), had higher overall stage (86% vs. 69% with stage III/IV, p < 0.01), and more frequent node involvement (89% vs. 49%, p < 0.01). Lower tumor stage, Helicobacter pylori positivity, and surgical intervention were associated with significantly longer median survival (all p < 0.05), which was similar in our study compared to SEER (median 12.6 vs. 9.0 months, p = 0.26). CONCLUSIONS: Patients with GSRC within the Los Angeles County population have different clinical characteristics compared to what has been reported in SEER. Our cohort was younger, and despite having more advanced disease, did not have shorter survival. Further study is needed to better identify protective and risk factors in this population and improve understanding of the etiopathogenesis and natural history of this malignancy.

RESUMEN

PURPOSE OF REVIEW: Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by progressive fibroinflammatory destruction of the intrahepatic and/or extrahepatic bile ducts. It is associated with a significantly increased risk of malignancy, particularly cholangiocarcinoma (CCA). In this review, we discuss what is currently known about the epidemiology of and risk factors for CCA in PSC as well as recent advances in its prevention, diagnosis, and surveillance. RECENT FINDINGS: An area of major focus has been finding novel biomarkers (in serum, bile, and urine) for CCA. With the advancement of computing power, metabolomic and proteomic approaches, among other methods, may provide enhanced capability for differentiating between benign and malignant bile duct disease. Another area of focus has been the approach to CCA surveillance in PSC; a recent study has found that CCA surveillance in patients with PSC is associated with improved outcomes, including increased survival, thus advocating for its importance. SUMMARY: Despite ongoing advancements in the study of PSC-associated CCA, early diagnosis of CCA remains difficult, treatment options are limited, and prognosis is often consequently poor. Continued research in the development of high-accuracy diagnostic tools, novel biomarkers, and surveillance techniques may help to increase the likelihood of diagnosing CCA at earlier stages, when therapeutic options have the highest likelihood of resulting in cure.

RESUMEN

Non-variceal upper gastrointestinal (GI) bleeding is a significant cause of morbidity and mortality. Traditionally, through-the-scope (TTS) clips, thermal therapy, and injection therapies are used to treat GI bleeding. In this review, we provide an overview of novel endoscopic treatments that can be used to achieve hemostasis. Specifically, we discuss the efficacy and applicability of over-the-scope clips, hemostatic agents, TTS doppler ultrasound, and endoscopic ultrasound, each of which offer an effective method of reducing rates of GI rebleeding.

RESUMEN

Autoimmune optic papillitis is a rare disorder that causes progressive visual loss, often treated with rituximab (RTX). However, its use is not without risks. Here, we present a 51-year-old man who experienced vision loss because of autoimmune optic papillitis, which was well-controlled with RTX. Four years later, the patient developed abdominal pain and diarrhea and was found to have RTX-induced Crohn's disease (CD). The patient failed treatment with azathioprine, but was subsequently able to achieve clinical and endoscopic remission of his CD with ustekinumab, while continuing RTX therapy for autoimmune optic papillitis. This case report describes the efficacy of the anti-interleukin 12/23 monoclonal antibody in inducing remission of RTX-induced CD.
