Falls are common, morbid, and predictable in patients with cirrhosis

Animal naming test stratifies the risk of falls and fall-related fractures in patients with cirrhosis

This study aimed to determine the relationship between animal naming test (ANT), falls, and fall-related fractures in patients with cirrhosis. Cognitive impairment and frailty were assessed using ANT and Karnofsky performance status (KPS), respectively. Factors stratifying the risk of previous falls and fall-related fractures within 1 year were assessed using a logistic regression model. Factors affecting patient performance in ANT were evaluated using multiple regression analysis. Of the 94 patients, 19% and 5% experienced falls and fall-related fractures, respectively. The performance in ANT was worse in patients who experienced falls (11 vs. 18; p < 0.001) and fall-related fractures (8 vs. 16; p < 0.001) than in those who did not. After adjustment, females, KPS, and ANT (odds ratio [OR], 0.78; 95% confidence interval [CI], 0.65-0.93; p = 0.005) were associated with falls, while ANT was significantly associated with fall-related fractures (OR, 0.56; 95% CI 0.35-0.88; p = 0.012). Age and education affected the performance in ANT, whereas the use of Oriental zodiac did not. The ANT is useful for stratifying the risk of falls and fall-related fractures in patients with cirrhosis. The effects of age and education should be considered when applying ANT in the Japanese population.

A modified Hospital Frailty Risk Score for patients with cirrhosis undergoing abdominal operations

BACKGROUND AND AIMS

Existing tools for perioperative risk stratification in patients with cirrhosis do not incorporate measures of comorbidity. The Hospital Frailty Risk Score (HFRS) is a widely used measure of comorbidity burden in administrative dataset analyses. However, it is not specific to patients with cirrhosis, and application of this index is limited by its complexity.

APPROACH AND RESULTS

Adult patients with cirrhosis who underwent nontransplant abdominal operations were identified from the National Inpatient Sample, 2016-2018. Adjusted associations between HFRS and in-hospital mortality and length of stay were computed with logistic and Poisson regression. Lasso regularization was used to identify the components of the HFRS most predictive of mortality and develop a simplified index, the cirrhosis-HFRS. Of 10,714 patients with cirrhosis, the majority were male, the median age was 62 years, and 32% of operations were performed electively. HFRS was associated with an increased risk of both in-hospital mortality (OR=6.42; 95% CI: 4.93, 8.36) and length of stay (incidence rate ratio [IRR]=1.79; 95% CI: 1.72, 1.88), with adjustment. Using lasso, we found that a subset of 12 of the 109 ICD-10 codes within the HFRS resulted in superior prediction of mortality in this patient population (AUC = 0.89 vs. 0.79, p < 0.001).

CONCLUSIONS

While the 109-component HFRS was associated with adverse surgical outcomes, 12 components accounted for much of the association between the HFRS and mortality. We developed the cirrhosis-HFRS, a tool that demonstrates superior predictive accuracy for in-hospital mortality and more precisely reflects the specific comorbidity pattern of hospitalized patients with cirrhosis undergoing general surgery procedures.

Validation and Improvement of the Saga Fall Risk Model: A Multicenter Retrospective Observational Study

Purpose

We conducted a pilot study in an acute care hospital and developed the Saga Fall Risk Model 2 (SFRM2), a fall prediction model comprising eight items: Bedriddenness rank, age, sex, emergency admission, admission to the neurosurgery department, history of falls, independence of eating, and use of hypnotics. The external validation results from the two hospitals showed that the area under the curve (AUC) of SFRM2 may be lower in other facilities. This study aimed to validate the accuracy of SFRM2 using data from eight hospitals, including chronic care hospitals, and adjust the coefficients to improve the accuracy of SFRM2 and validate it.

Patients and Methods

This study included all patients aged ≥20 years admitted to eight hospitals, including chronic care, acute care, and tertiary hospitals, from April 1, 2018, to March 31, 2021. In-hospital falls were used as the outcome, and the AUC and shrinkage coefficient of SFRM2 were calculated. Additionally, SFRM2.1, which was modified from the coefficients of SFRM2 using logistic regression with the eight items comprising SFRM2, was developed using two-thirds of the data randomly selected from the entire population, and its accuracy was validated using the remaining one-third portion of the data.

Results

Of the 124,521 inpatients analyzed, 2,986 (2.4%) experienced falls during hospitalization. The median age of all inpatients was 71 years, and 53.2% were men. The AUC of SFRM2 was 0.687 (95% confidence interval [CI]:0.678-0.697), and the shrinkage coefficient was 0.996. SFRM2.1 was created using 81,790 patients, and its accuracy was validated using the remaining 42,731 patients. The AUC of SFRM2.1 was 0.745 (95% CI: 0.731-0.758).

Conclusion

SFRM2 showed good accuracy in predicting falls even on validating in diverse populations with significantly different backgrounds. Furthermore, the accuracy can be improved by adjusting the coefficients while keeping the model's parameters fixed.

Assessment of lower limb muscle strength can predict fall risk in patients with chronic liver disease

Falls are caused by a combination of factors, including loss of lower limb muscle strength (LMS), and associated with declined performance status (PS). Age-related sarcopenia is generally associated with decreased muscle mass and strength of lower limb muscle but without a noticeable loss of those of upper limb or trunk muscle. However, no reports have focused on falls or LMS in chronic liver disease (CLD) patients. This study is the first to analyze the risk factors for falls in patients with CLD, focusing on LMS measurement using the Locomoscan. This study enrolled 315 CLD patients whose LMS was measured. The patients who experienced falls more than 1 year ago or during the observation period were classified as those who experienced falls. We found that risk factors for falls were PS1/2 and decreased LMS (< 0.32 N/kg). The group with sarcopenia had a higher frequency of decreased LMS (54 vs. 26%, p = 0.001) and falls (24 vs. 4.4%, p < 0.001) compared to the non-sarcopenia group. This study found that decreased LMS was an independent risk factor for falls. Assessment of LMS may be used as a better marker associated with the risk of falls in patients with CLD.

Prognostic models in alcohol-related liver disease and alcohol-related hepatitis

Alcohol-associated liver disease (ALD) and alcohol-associated hepatitis (AH) are dynamic disorders whose prognosis can be challenging to determine. A number of prognostic models have been developed to determine likelihood of death, when to refer for liver transplant (LT) and the role for glucocorticoids. Often these models were created with a specific application in mind but were found to have additional applications with further study. Those prognostic models that have stood the test of time are easy to use, have clear interpretations and employ objective parameters. These parameters most often include total bilirubin, INR and creatinine among other data points. Ideally, these models could be utilized at all phases of disease but in most, it is important for clinicians to consider drinking history and how it might alter the determined scores. Herein we provide a brief review of prognostic models in ALD and AH and provide practical tips and considerations to successfully make use of these tools in a clinical setting.

Risk of injuries before and after a diagnosis of cirrhosis: A population-based cohort study

BACKGROUND

Cirrhosis is often asymptomatic prior to decompensation. Still, cognitive impairment and sarcopenia may be present before decompensation, possibly increasing the risk of injuries. We estimated the risk of injuries during the period shortly before and after cirrhosis diagnosis.

METHODS

All patients (N=59,329) with a diagnosis of cirrhosis from 1997 to 2019 were identified from the Swedish National Patient Register. We used a self-controlled case series design to compare the incidence rates (IR) of injuries during a "diagnostic period" (within 3 months before or after the cirrhosis diagnosis date) to a self-controlled "prediagnostic period" (the same 6 calendar months 3 years before diagnosis), using conditional Poisson regression. Injuries were ascertained from the National Patient Register.

RESULTS

We identified 23,733 (40.0%) patients with compensated and 35,595 (60.0%) with decompensated cirrhosis. There were 975 injuries (IR 2.8/1000 person-months) during the prediagnostic period, and 3610 injuries (IR 11.6/1000 person-months) identified during the diagnostic period. The IR ratio was 8.1 (95% CI 7.5-8.7) comparing the diagnostic period with the prediagnostic period. For patients with compensated cirrhosis, the risk increment of injuries was highest just before the diagnosis of cirrhosis, whereas the risk increase was highest shortly after the diagnosis for those with decompensation.

CONCLUSIONS

The incidence of injuries increases shortly before and after the diagnosis of cirrhosis. These findings indicate that cirrhosis is frequently diagnosed in conjunction with an injury, and highlight the need for injury prevention after cirrhosis diagnosis, especially in patients with decompensation.

Palliative clinical trials in advanced chronic liver disease: Challenges and opportunities

Patients with advanced chronic liver disease have a complex symptom burden and many are not candidates for curative therapy. Despite this, provision of palliative interventions remains woefully inadequate, with an insufficient evidence base being a contributory factor. Designing and conducting palliative interventional trials in advanced chronic liver disease remains challenging for a multitude of reasons. In this manuscript we review past and ongoing palliative interventional trials. We identify barriers and facilitators and offer guidance on addressing these challenges. We hope that this will reduce the inequity in palliative care provision in advanced chronic liver disease.

Lactulose therapy for patients with cirrhosis, portal hypertension, and poor patient-reported outcomes: The Mi-Kristal trial

BACKGROUND AND AIMS

Poor patient-reported outcomes (PROs) are common in cirrhosis, including poor sleep and health-related quality of life (HRQOL). HE is a major driver of poor PROs. Many clinicians initiate lactulose therapy to address poor PROs. PRO-triggered therapy, however, has not been studied till date.

METHODS

We conducted a 28-day randomized trial of crystalline lactulose therapy (20 g BID) compared with no HE-directed therapy in 52 patients with cirrhosis, portal hypertension, no prior HE, and high Work Productivity and Activity Impairment scores (0-10) attributed to cirrhosis. The primary outcome was change in global HRQOL measured with Short Form-8 Health Survey. Secondary outcomes included change in Animal Naming Test score, Work Productivity and Activity Impairment, and sleep quality (scored "very bad" to "very good").

APPROACH AND RESULTS

Overall, 52 patients underwent randomization; 3 subjects withdrew from the crystalline lactulose arm (1 before medication initiation, 1 due to an unrelated condition, and 1 due to high baseline bowel movements). The average age was 60 years, the average Model for Endstage Liver Disease-Sodium score was 10.5, and 56% of the patients had ascites. Baseline bowel movements were 2.3/day, with 35% of the patients having Bristol Stool Scale >4. At 28 days, there was no improvement in HRQOL: patients receiving crystalline lactulose had an 8.1-point (95% CI: 3.7-12.4) increase compared with 6.6 (95% CI: 2.3-10.8) in the control group ( p = 0.6). Lactulose was associated with a significantly ( p = 0.002) increased Animal Naming Test score (3.7, 95% CI: 2.1-5.4) versus the control group (0.2, 95% CI: -1.7, 1.4). Lactulose users reported more good sleep (92% vs. 52%, p = 0.001) and lower activity impairment (3.0 vs. 4.8, p = 0.02).

CONCLUSIONS

Lactulose improves sleep and activity impairment in patients with poor PROs. We did not observe any improvement in global HRQOL after 28 days using the Short Form-8 Health Survey instrument.

A chair-stand time of greater than 15 seconds is associated with an increased risk of death and hospitalization in cirrhosis

Background

Frailty is a clinical state of increased vulnerability and is common in patients with cirrhosis. The liver frailty index (LFI) is a validated tool to evaluate frailty in cirrhosis, comprising of grip strength, chair stands, and balance tests. The chair-stand test is an easy to conduct frailty subcomponent that does not require specialized equipment and may be valuable to predict adverse clinical outcomes in cirrhosis. The objective of this study was to determine if the chair-stand test is an independent predictor of mortality and hospitalization in cirrhosis.

Methods

A retrospective review of 787 patients with cirrhosis was conducted. Chair-stand times were collected at baseline in person and divided into three groups: <10 seconds (n = 276), 10-15 seconds (n = 290), and >15 seconds (n = 221). Fine-Gray proportional hazards regression models were used to evaluate the association between chair-stand times and the outcomes of mortality and non-elective hospitalization.

Results

The hazard of mortality (HR 3.21, 95% CI 2.16%-4.78%, p <0.001) and non-elective hospitalization (HR 2.24, 95% CI 1.73%-2.91%, p <0.001) was increased in group 3 in comparison to group 1. A chair-stand test time >15 seconds had increased all-cause mortality (HR 2.78, 95% CI 2.01%-3.83%, p <0.001) and non-elective hospitalizations (HR 1.84, 95% CI 1.48%-2.29%, p <0.001) compared to <15 seconds.

Conclusions

A chair-stand test time of >15 seconds is independently associated with mortality and non-elective hospitalizations. This test holds promise as a rapid prognostication tool in cirrhosis. Future work will include external validation and virtual assessment in this population.

Time-Varying Hazard of Patient Falls in Hospital: A Retrospective Case-Control Study

This study aims to evaluate the association between patient falls and relevant factors and to quantify their effect on fall risk. This is a retrospective case-control study using the secondary data collected from a tertiary general hospital. Study subjects were 450 patients who were admitted to the hospital between January 2016 and December 2020. The prevalence of falls was associated with the fall risk level by the Morse Fall Scale (MFS) and individual status at admission including history of admission, dizziness, sleep disorder, bowel dysfunction, and urinary incontinence. The odds ratios of patient falls were higher in the low-risk group by the MFS score (odds ratio (OR) = 2.61, p < 0.001) and the high-risk group (OR = 5.51, p < 0.001) compared to the no-risk group. The hazard ratio of patient falls was higher in the high-risk group by the MFS score (hazard ratio (HR) = 3.85, p < 0.001). The MFS had a significant explanatory power to predict fall risk. Sleep disorder and urinary incontinence were the significant factors influencing patient falls.

Accumulating awareness on the clinical significance and relevance of frailty in cirrhosis: Time to dig deeper into mechanistic basis!

Frailty corresponds to an emerging construct in the hepatology which is originally introduced as a validated geriatric syndrome regarding increased vulnerability to pathophysiological stressors. As for patients with cirrhosis, the presence of frailty is indicative of debilitating conditions that subjects are prone to deleterious acute insults and have difficulties to restore even if the underlying liver function partially returned to normal levels. Since this conceptual development, a variety of tools assessing frailty have been proposed and evaluated in the context of cirrhosis. A recent performance-based metric for frailty, designated as Liver Frailty Index, has broadly been applied in patients with cirrhosis and exhibited acceptable predictive ability in relation to disease progression, mortality and hospitalization. However, those functional tests measuring frailty may be impossible to perform in circumstance that patients are critically ill or undergoing detrimental events. An interesting modality indicates the use of alternative tests to evaluate frailty, which may be more adaptable and of choice for specific subgroups. The interrelation between frailty and various cirrhosis-associated pathological entities is of clinical importance and implication. Noticeably, it is imperative to clarify these complex linkages to highlight novel therapeutic targets or interventional endpoints. The efficient and effective management of frailty is still challenging, but many attempts have been made to overcome barriers of affordability and availability. Some clinical trials on small scale revealed that home-based exercise and individualized nutrition therapy show benefits in patients with cirrhosis, and high adherence to the treatment regimen may direct better efficacy and performance.

Targets and study design for symptom-focused trials aimed at patients with cirrhosis: An expert consensus

BACKGROUND

Symptom-focused trials are critically needed for patients with cirrhosis. However, this work would benefit from standard processes and validated measures.

METHODS

A writing group was formed among hepatologists, nurses, palliative care providers, pharmacists, and clinical trial experts focused on symptom management in patients with cirrhosis to define the key (1) components of trial design, (2) symptom targets, (3) measurement, and (4) outcomes for each target. From July 2022 to January 2023, panelists participated in an iterative process of developing and arriving at a consensus for each component. The goal was to provide consensus definitions that can be operationalized in future clinical trials, including for patients with cirrhosis.

RESULTS

The panel reached a consensus on key reporting features for clinical trials, along with considerations for study design. Nine key symptom targets (muscle cramps, pruritus, pain, fatigue, sexual dysfunction, sleep disorders, depression and anxiety, nausea/vomiting, and dyspnea/breathlessness) were identified. The panel selected instruments that can be considered for clinical trials based on psychometric validation and previous experience. The panel identified ongoing needs, including instrument validation, safety data, evidence about non-pharmacologic interventions, and comparative effectiveness studies.

CONCLUSION

This expert panel identified key design, reporting, and measurement elements to standardize processes and measures in future symptom-focused clinical trials in the context of cirrhosis.

Medical malpractice claims in Hepatology: Rates, Reasons, and Results

BACKGROUND

Clinicians are motivated to provide safe, high-quality care to patients with chronic liver disease. This includes the desire to avoid litigation. Data are limited regarding the actual sources of medicolegal risk in chronic liver disease.

METHODS

We conducted a review of a national liability insurer (Candello) with an additional granular analysis of our institution's registry of liability claims. We included closed cases involving chronic liver disease-related encounters between 2012 and 2021. We determined rates of legal claims from a denominator of unique patients with cirrhosis or transplant care seen over the study period.

RESULTS

Local database: We retrieved 39 claims of which 15 involved patients with non-cirrhotic chronic liver disease, 13 involved cirrhosis (0.06% incidence), and 11 involved patients who underwent transplantation (0.6% incidence). Most claims involved periprocedural complications. Others included adverse reactions to prophylactic plasma transfusion, medication-induced HE, and falls/fractures.

NATIONAL DATABASE

We found 94 claims related to liver disease out of 102,575 (0.09%) total claims. Overall, 56% involved diagnosis-related issues (failure/delay in ordering a diagnostic test, failure to appreciate and reconcile a symptom/sign or result, or the misinterpretation of a diagnostic study). Miscommunication between providers and between providers and patients was implicated in 22% of cases. Patient behavior-related factors (nonadherence with scheduled appointments, treatments, or diagnostic testing) factored in 20% of cases. Selection or the management of therapy played a role in 7% of cases. Very rarely were cases associated with technical skill (4%), house staff supervision (3%), or weekend/holiday care (1%). Fifty-one (55%) claims involved HCC.

CONCLUSION

We provide the rates and reasons for medical malpractice claims in hepatology.

Sarcopenia and Frailty in Cirrhosis

Sarcopenia and frailty are frequent in cirrhosis, and both contribute to increased morbidity and mortality. The complex pathogenesis of sarcopenia in cirrhosis is mainly determined by hyperammonemia and malnutrition. Sarcopenia/frailty screening and reevaluation should be undertaken in all cirrhotic patients. Frailty tests are useful in the ambulatory setting, whereas the computed tomography scan is the diagnostic gold standard for sarcopenia. To manage sarcopenia/frailty, a multidisciplinary team should develop a personalized comprehensive care plan that includes patient education, protein/calorie intake goals, late evening meals, exercise programs, and micronutrient replenishment. In selected patients, branched-chain amino acid and testosterone supplements may also be beneficial.

Frailty as a predictor of poor outcomes among patients awaiting liver transplant: a systematic review and meta-analysis

Aim

This review sought to evaluate the significance of a functional assessment for liver transplant candidates, i.e., frailty, in the pre-transplant setting and its association with mortality and morbidities.

Background

Liver transplantation (LT) remains the treatment of choice for patients with end-stage liver disease. Due to the shortage of organs for LT, a careful selection of suitable recipients is essential. Frailty, a measure of physiologic reserve and increased vulnerability to stressors, was initially used in geriatrics and then introduced to the field of transplantation for better patient selection.

Methods

PubMed, Scopus, and Web of Science databases were reviewed up until January 2023. The search terms included: "frail*", "liver", and "transplant*". A Meta-analysis was conducted for the hazard ratios (HRs) obtained from the COX regression models. Fifty-five studies were included in this review; ten were included in the meta-analysis.

Results

The prevalence of frailty varied from 2.82% to 70.09% in the studies. Meta-analysis showed that overall frailty had a significant association with mortality (pooled adjusted HR [95%CI]: 2.66 [1.96-3.63]). Subgroup analyses revealed that both the Liver Frailty Index and Fried Frailty Index were significantly associated with mortality. Furthermore, these studies have demonstrated that this population's frailty is associated with ascites, hepatic encephalopathy, and esophageal varices.

Conclusion

According to emerging evidence, frailty is associated with increased morbidity and mortality of the patients on the LT waiting list. Further randomized trials are required to determine the efficacy and safety of variable interventions in the frail population.

Falls are an underappreciated driver of morbidity and mortality in cirrhosis

Predicting which patients with cirrhosis will develop overt hepatic encephalopathy: Beyond psychometric testing

It remains challenging to identify covert hepatic encephalopathy and predict progression to overt hepatic encephalopathy. Psychometric testing is a widely used diagnostic modality, but it is often inaccurate and difficult to implement in diverse populations, making it a less than ideal assessment. Alternatively, by using easily accessible data from the electronic health record, simple clinical assessment tools, and patient-reported outcomes, we may be better able to predict hepatic encephalopathy across multiple populations. Furthermore, incorporation of patient-reported outcomes into our diagnostic toolset not only aids detection of covert hepatic encephalopathy and prediction of overt hepatic encephalopathy, but also allows us to target therapies and track their impact. Herein, we outline a potential algorithm based on these easily integrated tools to promote patient risk-stratification and early therapeutic intervention.

Risk of Fractures and Subsequent Mortality in Alcohol-Related Cirrhosis: A Nationwide Population-Based Cohort Study

BACKGROUND AND AIMS

Alcohol-related cirrhosis is linked to increased risk of fractures, but this has seldom been quantified nationally or compared against control subjects without cirrhosis. Here, we determined the rate and risk of fractures and postfracture mortality in patients with alcohol-related cirrhosis compared with individuals from the general population.

METHODS

In this nationwide population-based cohort study, data were retrieved from the Swedish National Patient Registry on 25,090 patients with alcohol-related cirrhosis from 1969-2016. Patients were matched for sex, age, and municipality with 239,458 control subjects from the Swedish Total Population Registry. Cox regression models were fitted to investigate the rates of fractures and postfracture mortality. The cumulative incidence of fractures was calculated while accounting for competing risks (death or liver transplantation).

RESULTS

A total of 48,635 fractures occurred during 3,468,860 person-years of follow-up. Patients with alcohol-related cirrhosis had a higher fracture rate per 1000 person-years (38.7) than control subjects (13.3; adjusted hazard ratio, 3.8; 95% confidence interval, 3.6-3.9). The cumulative incidence of fractures was elevated for patients the first 19 years of follow-up, with a 5-year risk of 9.6% compared with 4.5% for control subjects. Patients with alcohol-related cirrhosis had a higher postfracture mortality rate compared with control subjects who also experienced a fracture, at both 30 days (adjusted hazard ratio, 1.6; 95% confidence interval, 1.4-1.8) and 1 year (adjusted hazard ratio, 1.8; 95% confidence interval, 1.7-2.0).

CONCLUSIONS

Alcohol-related cirrhosis is associated with an almost 4-fold increased fracture rate, a higher risk of fractures the first 2 decades after initial diagnosis, and higher postfracture mortality. Preventive interventions to reduce modifiable fracture risk factors in this population are justified.

Review article: current and emerging therapies for the management of cirrhosis and its complications

BACKGROUND

Cirrhosis is increasingly common and morbid. Optimal utilisation of therapeutic strategies to prevent and control the complications of cirrhosis are central to improving clinical and patient-reported outcomes.

METHODS

We conducted a narrative review of the literature focusing on the most recent advances.

RESULTS

We review the aetiology-focused therapies that can prevent cirrhosis and its complications. These include anti-viral therapies, psychopharmacological therapy for alcohol-use disorder, and the current landscape of clinical trials for non-alcoholic steatohepatitis. We review the current standard of care and latest developments in the management of hepatic encephalopathy (HE), ascites and hepatorenal syndrome. We evaluate the promise and drawbacks of chemopreventative therapies that have been examined in trials and observational studies which may reduce the risk of hepatocellular carcinoma and cirrhosis complications. Finally, we examine the therapies which address the non-pain symptoms of cirrhosis including pruritis, muscle cramps, sexual dysfunction and fatigue.

CONCLUSION

The improvement of clinical and patient-reported outcomes for patients with cirrhosis is possible by applying evidence-based pharmacotherapeutic approaches to the prevention and treatment of cirrhosis complications.

Portal vein thrombosis is associated with an increased risk of bone fractures

Background

Portal vein thrombosis (PVT) is a rare but severe disease that often leads to portal hypertension-related complications. It is well-known that patients with portal hypertension associated with liver cirrhosis are at increased risk for bone fractures, however data on the impact of PVT on fracture risk are lacking.

Aims

This study aimed to explore the impact of PVT on the incidence of bone fractures in a large German primary care cohort.

Methods

Patients with PVT were extensively matched to non-PVT individuals in a 1:5 ratio. The primary outcome of the study was the incidence of any bone fracture.

Results

This study included 596 patients with PVT and 2,980 non-PVT individuals. During five years of follow-up, the cumulative incidence of bone fractures was significantly higher in PVT patients (n = 87, 13.6%) than in those without PVT (n = 186, 6.7%) (p<0.001). In Cox-regression analyses, PVT was positively associated with bone fractures (HR: 2.16; 95% CI: 1.59–2.93). This association was stronger in women (HR: 2.55; 95% CI: 1.65–3.95) than in men (HR: 1.87; 95% CI: 1.22–2.87). The strongest association was observed in the age group 51–60 years (HR: 2.50, 95% CI: 1.40–4.47). The association between PVT and bone fractures was maintained in subgroup analyses of patients with (HR: 2.03, 95% CI: 1.13–3.63) and without liver cirrhosis (HR: 1.82, 95% CI: 1.28–2.58).

Conclusions

PVT is independently associated with a higher incidence of bone fractures. Patients with PVT should be critically evaluated for fracture risk and preventive measures should be considered.

Incidence and Risk Factors for Cerebrovascular-Specific Mortality in Patients with Colorectal Cancer: A Registry-Based Cohort Study Involving 563,298 Patients

Simple Summary

Previous studies have shown that the occurrence of cerebrovascular-specific diseases was common in cancer patients. However, the association between colorectal cancer and cerebrovascular-specific diseases remains to be fully elucidated. In this large-population cohort study, we found that the mortality of cerebrovascular-specific diseases mortality in colorectal cancer patients was significantly higher than the general US population. In addition, we investigated several potential predictors of cerebrovascular-specific diseases mortality in colorectal cancer. This study may be useful for the prevention, risk stratification and therapeutic optimization of cerebrovascular-specific diseases in colorectal cancer patients.

Abstract

Background: Colorectal cancer (CRC) is one of the most prevalent diseases and the second leading cause of death worldwide. However, the relationship between CRC and cerebrovascular-specific mortality (CVSM) remains elusive, and less is known about the influencing factors associated with CVSM in CRC. Here, we aimed to analyze the incidence as well as the risk factors of CVSM in CRC. Methods: Patients with a primary CRC diagnosed between 1973 and 2015 were identified from the Surveillance Epidemiology and End Results database, with follow-up data available until 31 December 2016. Conditional standardized mortality ratios were calculated to compare the incidence of CVSM between CRC patients and the general U.S. population. Univariate and multivariate survival analyses with a competing risk model were used to interrogate the risk factors for CVSM. Results: A total of 563,298 CRC individuals were included. The CVSM in CRC patients was significantly higher than the general population in all age subgroups. Among the competing causes of death in patients, the cumulative mortality caused by cerebrovascular-specific diseases steadily increased during the study period. While age, surgery, other/unknown race and tumors located at the transverse colon positively influenced CVSM on both univariate and multivariate analyses, male patients and those who had radiotherapy, chemotherapy, a more recent year (2001–2015) of diagnosis, a grade II or III CRC, rectal cancer, or multiple primary or distant tumors experienced a lower risk of CVSM. Interpretation: Our data suggest a potential role for CRC in the incidence of CVSM and also identify several significant predictors of CVSM that may be helpful for risk stratification and the therapeutic optimization of cerebrovascular-specific diseases in CRC patients.

Deprescribing zolpidem reduces falls and fractures in patients with cirrhosis

Background & Aims

Benzodiazepines are associated with an increased risk of harm in patients with cirrhosis. However, stopping benzodiazepines must be done with care to avoid withdrawal or other unintended consequences. The impact of deprescribing on patients with cirrhosis is unknown.

Methods

We emulated a hypothetical 3-year trial of benzodiazepine deprescription among Medicare enrollees with compensated cirrhosis who lacked other life-limiting diagnoses. All received continuous benzodiazepine prescriptions for the 6-months prior to their diagnosis of cirrhosis. During a 90-day landmark period following their diagnosis of cirrhosis, patients were classified as complete deprescribers (no benzodiazepines dispensed), continuous users, or partial deprescribers. We used inverse probability treatment weighting to compare complete deprescribers to continuous users of traditional benzodiazepines and zolpidem. Outcomes accounted for competing risk of mortality and included incident decompensation (hepatic encephalopathy, ascites, or variceal bleeding), fractures, falls, and alcohol-related hospitalizations.

Results

There were 1,651 and 1,463 continuous users of traditional benzodiazepines and zolpidem, respectively, and 728 complete deprescribers. Patients were aged a median of 68 years, 24% had alcohol-related cirrhosis. There was no difference in the risk of death or decompensation for continuous users and deprescribers. Among deprescribers of traditional benzodiazepines, there was no improvement in the risk of falls or fractures. However, compared to continuous zolpidem users, deprescribers had a lower risk of falls (23.2% vs. 31%, p = 0.04) and fractures (21% vs. 29%, p = 0.02).

Conclusions

Deprescribing zolpidem reduces the risk of falls and fractures. However, deprescribing benzodiazepines does not improve the risk of decompensation. Efforts to safely address the indications for benzodiazepines such as insomnia and anxiety are urgently needed.

Lay summary

Many people with cirrhosis have anxiety, depression, and sleep disorders. Increasingly, patients with cirrhosis are treated with sedating medications called benzodiazepines, including valium, alprazolam (‘Xanax’), clonopin, and the sleep-aid zolpidem (‘Ambien’), which can cause falls, broken bones, and maybe other brain disorders. For this reason, many researchers are interested in trials of ‘deprescribing’ (stopping) benzodiazepines. However, no trials have been performed. We used health record data to simulate a trial of deprescribing. We found that stopping benzodiazepines may reduce the chance of falls or broken bones, but it does not improve survival or liver health.

•

Benzodiazepines are frequently and increasingly prescribed to patients with cirrhosis.

•

Benzodiazepines may increase the risk of falls and fractures and hepatic encephalopathy.

The 5Ms of Geriatrics in Gastroenterology: The Path to Creating Age-Friendly Care for Older Adults With Inflammatory Bowel Diseases and Cirrhosis

The number of Americans 65 years or older in 2060 will be more than double what it was in 2014. Approximately 40% of patients seen in gastroenterology (GI) and hepatology practices in the United States are 60 years or older. Adapting care delivery models, curating data on shifting risk-benefit decisions with geriatric syndromes, understanding appropriate assessments, and focusing on tailored implementation strategies are challenges that are actively confronting us as we provide care for a burgeoning population of older adults. Limited availability of geriatric specialists results in an onus of specialists caring for older adults, such as gastroenterologists, to innovate and develop tailored, comprehensive, and evidence-based care for adults in later life stages. In this article, we present the 5M framework from geriatrics to achieve age-friendly healthcare. The 5Ms are medications, mind, mobility, multicomplexity, and what matters most. We apply the 5M framework to 2 chronic conditions commonly encountered in clinical GI practice: inflammatory bowel diseases and cirrhosis. We highlight knowledge gaps and outline future directions to expand evidence-based care and advance the creation of age-friendly GI care.

Cognitive Impairment and Cirrhosis in Older Patients: A Systematic Review

Prevalence of cirrhosis and hepatic encephalopathy (HE) in older patients receiving care in long-term care settings is unknown. This systematic review aimed to identify potential factors associated with HE and cognitive impairment in older patients with cirrhosis. A PubMed search of English-language articles published between January 1, 2000, and November 3, 2021, was conducted to identify studies in adults with cirrhosis relevant to cognitive impairment and/or HE (e.g., fall, frailty, and sarcopenia). Of 2,879 English-language publications, 24 were included. In patients with cirrhosis, falls were increased in the presence of HE and were associated with increased injury risk. Frailty was associated with HE development and cognitive impairment in patients with cirrhosis. Further, cognitive impairment and frailty were predictive of HE-related hospitalizations. Sarcopenia increased the risk of developing HE. Furthermore, specific medications increased the risk of developing HE. Risk reduction and management of patients with HE are critical to prevent negative outcomes.
