Nonalcoholic fatty liver disease now dominates the practice of hepatology, and hepatic steatosis may be detected as an incidental finding on imaging despite normal aminotransferase levels. It is important to identify patients at risk of progressive fibrosis.

Calculation of the fibrosis-4 (FIB-4) score (based on age, alanine and aspartate aminotransferase [ALT and AST] levels, and platelet count by the primary care provider, using either an online calculator or the dot phrase “.fib4” in Epic) is a useful first step. If the value is low (with a high negative predictive value for advanced fibrosis), the patient does not need to be referred but can be managed for risk factors for nonalcoholic fatty liver disease. If the value is high, suggesting advanced fibrosis, the patient requires further evaluation. If the value is indeterminate, options for assessing liver stiffness include vibration-controlled transient elastography (with a controlled attenuation parameter to assess the degree of steatosis) and ultrasound elastography. A low liver stiffness score argues against the need for subspecialty management. An indeterminate score may be followed by magnetic resonance elastography, if available. An alternative to elastography is the enhanced liver fibrosis (ELF) blood test, based on serum levels of tissue inhibitor of metalloproteinases 1 (TIMP-1), amino-terminal propeptide of type III procollagen (PIIINP), and hyaluronic acid.

Among adults with type 2 diabetes, the presence of preserved ratio impaired spirometry (PRISm) was significantly associated with increased risk of mortality and both macro- and microvascular complications, as well as increased mortality, based on data from more than 20,000 individuals.

PRISm occurs in approximately 10% of the general population and has been identified as a predictor of adverse health outcomes including cardiorespiratory morbidity and mortality, Guochen Li, MD, of the Medical College of Soochow University, Suzhou, China, and colleagues wrote.

“A growing number of studies have demonstrated that impaired lung function and type 2 diabetes could trigger shared pathophysiological injuries, such as microangiopathy and chronic inflammation,” they said, but the potential role of PRISm as an early predictor of adverse outcomes in patients with type 2 diabetes has not been fully examined.

In a study published in the journal Chest, the researchers reviewed data from 20,047 individuals with type 2 diabetes in the UK Biobank, a population-based cohort of adults aged 37-73 years recruited between 2006 and 2010.

The main exposure was lung function based on spirometry. PRISm was defined as predicted forced expiratory volume per second (FEV1) less than 80%, with an FEV1/ forced vital capacity (FVC) ratio of at least 0.70. Individuals with normal spirometry (defined as predicted FEV1 ≥ 80% with an FEV1/FVC ratio ≥ 0.70) served as controls.

The primary outcomes were major complications of type 2 diabetes including macrovascular events (myocardial infarction, unstable angina, coronary heart disease [CHD], ischemic stroke, and any type of stroke), microvascular events (diabetic retinopathy and diabetic kidney disease) and mortality (all-cause, cardiovascular, and respiratory).

Overall, 16.9% of study participants (3385 patients) had obstructive spirometry and 22.6% (4521 patients) had PRISm. Compared with individuals with normal spirometry, those with PRISm were more likely to be current smokers, obese, and living in economically disadvantaged areas. Individuals with PRISm also were significantly more likely to be long-term patients with diabetes who were taking glucose-lowering or lipid-lowering drugs (P < .001 for all).

The median follow-up for each of the type 2 diabetes complications and mortality was approximately 12 years. Over this time, 5.0% of patients developed incident MI, 1.3% developed unstable angina, 15.6% had CHD, 3.5% had an ischemic stroke, and 4.7% had any type of stroke. As for microvascular events, 7.8% developed diabetic retinopathy and 6.7% developed diabetic kidney disease. A total of 2588 patients died during the study period (15.1%), including 544 from cardiovascular disease and 319 from respiratory disease.

PRISm was significantly associated with increased risk of each of the complications and mortality types. These associations persisted after adjusting for lifestyle and other factors. The fully adjusted hazard ratios for PRISm versus normal spirometry were 1.23 for MI, 1.23 for unstable angina, 1.21 for CHD, 1.38 for ischemic stroke, 1.41 for any type of stroke, 1.31 for diabetic retinopathy, and 1.38 for diabetic kidney disease. Adjusted HRs for mortality were 1.34, 1.60, and 1.56 for all-cause, cardiovascular, and respiratory mortality, respectively.

The researchers also found that adding PRISm to an office-based risk score significantly improved the risk classification and predictive power for type 2 diabetes complications with the exception of unstable angina and mortality. They found little evidence for an association with sex, smoking, or PRISm duration and any mortality types. However, in subgroup analyses by age, sex, and duration of diabetes, PRISm remained associated with increased risk of macrovascular and microvascular complications, as well as mortality.

Potential mechanisms for the association between PRISm and diabetes complications include the role of insulin resistance in the exacerbation of lung damage in patients with type 2 diabetes, the increased rate of supplemental oxygen use among individuals with PRISm, and the increased prevalence of pulmonary artery enlargement in the PRISm subjects, the researchers wrote.

The findings were limited by several factors including the prospective design, the homogeneous population of individuals primarily of British or Irish ancestry, and the exclusion of diabetic neuropathy from the analysis, the researchers noted.

However, the results were strengthened by the large cohort, use of professional spirometry, and relatively long follow-up. “The findings underscore the relevance of PRISm for prognostic classification in type 2 diabetes and its potential for optimizing prevention strategies in this condition,” they concluded.

The study was supported by the National Natural Science Foundation of China, Natural Science Foundation of Jiangsu Province, and the Priority Academic Program Development of Jiangsu Higher Education Institutions. The researchers reported no relevant financial relationships.

Medications taken by prospective fathers for inflammatory bowel disease (IBD) do not seem to affect fertility or birth outcomes, according to a systematic review and meta-analysis published in Clinical Gastroenterology and Hepatology.

The effort is the first meta-analysis to assess semen parameters and the risk of adverse outcomes in pregnancy for male patients with IBD who have taken biologics, thiopurines or methotrexate for the condition, the researchers said.

“We provide encouraging evidence that biologic, thiopurine, and methotrexate therapy among male patients with IBD are not associated with impairments in male fertility or with increased risk of adverse pregnancy outcomes,” said the researchers, led in part by John Gubatan, MD, instructor in medicine at Stanford (Calif.) University, who worked with investigators in Copenhagen and Toronto. “Taken together, our data support the safety of continuing biologics, thiopurines, or methotrexate across the reproductive spectrum.”

Questions of fertility and pregnancy outcomes are of particular importance in IBD, since patients are often diagnosed around the time of their reproductive years – about 30 years old for Crohn’s disease and 35 years old for ulcerative colitis. There has been far more research attention paid to female than male reproductive considerations, mainly the health of the fetus when the mother takes biologic therapy for IBD during pregnancy, which has generally found to be safe.

Their search found 13 studies with male IBD patients exposed to biologics, 10 exposed to thiopurines and 6 to methotrexate. Researchers extracted data on sperm count, sperm motility, and abnormal sperm morphology – three metrics considered a proxy for male fertility – as well as early pregnancy loss, preterm birth and congenital malformations.

Researchers found no differences between sperm count, motility or morphology between those exposed and not exposed to biologics, thiopurines and methotrexate, with a couple of exceptions. They actually found that sperm count was higher for thiopurine users, compared with nonusers, and there was only one study on methotrexate and abnormal sperm morphology, so there was no data to pool together for that comparison.

In a subgroup analysis, there was a trend toward higher sperm count in thiopurine users, compared with biologic or methotrexate users, but no differences were seen in the other parameters.

Similarly, there were no significant differences for users and nonusers of these medications for early pregnancy loss, preterm births or congenital malformations, the researchers found.

A prior systematic review suggested that azathioprine might be associated with low sperm count, but this new analysis calls that into question.

“Our results, which demonstrated that thiopurine use among male patients with IBD is associated with increased sperm count, refute this prior finding,” the researchers said. The previous finding, they noted, was only qualitative because the authors didn’t do an analysis to calculate effect size or determine statistical significance.

“Furthermore,” the researchers said, “our study included more updated studies and a greater number of patients.”

The authors disclosed no conflicts of interest.

TOPLINE:

Patients with early-stage breast cancer who do not adhere to adjuvant endocrine therapy as prescribed or stop early may face as much as a twofold higher risk of relapse or death, a new systematic review found.

METHODOLOGY:

• The investigators conducted a systematic literature search of five databases, looking for studies involving patients with nonmetastatic hormone receptor–positive breast cancer that were published between 2010 and 2020.
• Adequate adherence was defined as a medical possession ratio – the percentage of days the prescribed treatment dose of adjuvant endocrine therapy was available to the patient – of at least 80%.
• Medication nonpersistence was defined as a period in which no new adjuvant endocrine therapy prescriptions were filled before the scheduled end of treatment of 90-180 days, depending on the study.
• The impact of both parameters on event-free survival, which included breast cancer recurrence, disease-free survival, breast cancer–specific survival, and overall survival cancer was calculated.
• Of 2,026 articles retrieved, 14 studies, with sample sizes ranging from 857 to 30,573 patients, met the eligibility and quality criteria; 11 examined patient adherence, and 6 examined patient persistence.

TAKEAWAY:

• Of 10 studies that assessed event-free survival, 7 showed significantly worse survival for nonadherent or nonpersistent patients, at hazard ratios of 1.39-2.44.
• Of nine studies that examined overall survival, seven demonstrated a significantly higher risk for mortality in the groups with nonadherence and nonpersistence, at HRs of 1.26-2.18.
• The largest study, which included data on more than 30,000 patients in Taiwan, found that nonadherence and nonpersistence were associated with a significantly increased risk for mortality, at HRs of 1.98 and 2.18, respectively.

IN PRACTICE:

“The available data highlight the dangers of nonadherence and nonpersistence, showing an up to twofold higher risk of relapse or death for patients who do not use endocrine treatment as prescribed,” the researchers said. “Importantly, improving adherence and persistence represents a low-hanging fruit for increasing survival in luminal breast cancer.”

SOURCE:

The study, led by Finn Magnus Eliassen, MD, department of surgery, Stavanger (Norway) University Hospital, was published online on July 4 in BMC Cancer.

LIMITATIONS:

• The review is limited by the relatively small number of studies that met the eligibility criteria and by their heterogeneity, which ruled out a meta-analysis.
• There are no gold-standard definitions of adherence and persistence.

DISCLOSURES:

• No funding was declared. No relevant financial relationships were declared.
• A version of this article first appeared on Medscape.com.

• Adequate adherence was defined as a medical possession ratio – the percentage of days the prescribed treatment dose of adjuvant endocrine therapy was available to the patient – of at least 80%.
• Medication nonpersistence was defined as a period in which no new adjuvant endocrine therapy prescriptions were filled before the scheduled end of treatment of 90-180 days, depending on the study.
• The impact of both parameters on event-free survival, which included breast cancer recurrence, disease-free survival, breast cancer–specific survival, and overall survival cancer was calculated.
• Of 2,026 articles retrieved, 14 studies, with sample sizes ranging from 857 to 30,573 patients, met the eligibility and quality criteria; 11 examined patient adherence, and 6 examined patient persistence.

TAKEAWAY:

• Of 10 studies that assessed event-free survival, 7 showed significantly worse survival for nonadherent or nonpersistent patients, at hazard ratios of 1.39-2.44.
• Of nine studies that examined overall survival, seven demonstrated a significantly higher risk for mortality in the groups with nonadherence and nonpersistence, at HRs of 1.26-2.18.
• The largest study, which included data on more than 30,000 patients in Taiwan, found that nonadherence and nonpersistence were associated with a significantly increased risk for mortality, at HRs of 1.98 and 2.18, respectively.

IN PRACTICE:

“The available data highlight the dangers of nonadherence and nonpersistence, showing an up to twofold higher risk of relapse or death for patients who do not use endocrine treatment as prescribed,” the researchers said. “Importantly, improving adherence and persistence represents a low-hanging fruit for increasing survival in luminal breast cancer.”

SOURCE:

The study, led by Finn Magnus Eliassen, MD, department of surgery, Stavanger (Norway) University Hospital, was published online on July 4 in BMC Cancer.

LIMITATIONS:

• The review is limited by the relatively small number of studies that met the eligibility criteria and by their heterogeneity, which ruled out a meta-analysis.
• There are no gold-standard definitions of adherence and persistence.

DISCLOSURES:

• No funding was declared. No relevant financial relationships were declared.
• A version of this article first appeared on Medscape.com.

TOPLINE:

Although practice patterns vary widely, modified, reduced-dose FOLFIRINOX is as effective as standard, full-dose regimens for patients with metastatic pancreatic cancer in the first-line setting, and it is less likely to cause febrile neutropenia.

METHODOLOGY:

• No randomized controlled trials have directly compared modified FOLFIRINOX to standard FOLFIRINOX; this meta-analysis aims to fill the evidence gap.
• The investigators winnowed hundreds of first-line FOLFIRINOX studies down to 37 – 11 prospective and 26 retrospective analyses – to assess practice patterns and clinical outcomes.
• Dose information was grouped into four categories: planned dose in the standard FOLFIRINOX group; actual administered dose in the standard group; planned dose in the modified group; actual administered dose in the modified group.

TAKEAWAY:

• There were 12 types of “planned” dose reductions in FOLFIRINOX: 75%-100% oxaliplatin, 75%-100% irinotecan, 0%-100% 5-fluorouracil (5-FU) bolus, and 75%-133% 5-FU continuous injection.
• Doses actually delivered fell further to 54%-96% for oxaliplatin, 61%-88% for irinotecan, 0%-92% for 5-FU bolus, and 63%-98% 5-FU continuous injection.
• Despite the variations in dosing, reduced doses of FOLFIRINOX were associated with a slightly but not significantly higher objective response rate: 33.8% versus 28.2% for standard dosing (P = .1).
• The incidence of febrile neutropenia was significantly lower in the reduced-dose groups: 5.5% with modified FOLFIRINOX versus 11.6% with standard (P = .03).

IN PRACTICE:

Although the study supports reduced-dose regimens, it also shows that there is “still no consensus” on appropriate dose modification, the authors said. “The best dose modification protocol” remains to be determined and standardized for metastatic pancreatic cancer.

SOURCE:

The study was led by Kwangrok Jung at Seoul (South Korea) National University, and was published June 29 in Therapeutic Advances in Medical Oncology.

LIMITATIONS:

• Only 11 of the 37 studies were prospective.
• The studies often lacked key information, including the reason for dose reductions or detailed dose reduction protocols.
• Studies were also inconsistent in how they reported FOLFIRINOX dose modifications.

DISCLOSURES:

There was no funding for the study, and the investigators had no disclosures.

To the Editor:

Porocarcinoma, or malignant poroma, is a rare adnexal malignancy of a predominantly glandular origin that comprises less than 0.01% of all cutaneous neoplasms.^1,2 Although exposure to UV radiation and immunosuppression have been implicated in the malignant degeneration of benign poromas into porocarcinomas, at least half of all malignant variants will arise de novo.^3,4 Patients present with an evolving nodule or plaque and often are in their seventh or eighth decade of life at the time of diagnosis.² Localized trauma from burns or radiation exposure has been causatively linked to de novo porocarcinoma formation.^2,5 These suppressive and traumatic stimuli drive increased genetic heterogeneity along with characteristic gene mutations in known tumor suppressor genes.⁶

A 62-year-old man presented with a nonhealing wound on the right hand of 5 years’ duration that had previously been attributed to a penetrating injury with a piece of copper from a refrigerant coolant system. The wound initially blistered and then eventually callused and developed areas of ulceration. The patient consulted multiple physicians for treatment of the intensely pruritic and ulcerated lesion. He received prescriptions for cephalexin, trimethoprim-sulfamethoxazole, doxycycline, clindamycin, and clobetasol cream, all of which offered minimal improvement. Home therapies including vitamin E and tea tree oil yielded no benefit. The lesion roughly quadrupled in size over the last 5 years.

Physical examination revealed a 7.5×4.2-cm ulcerated plaque with ragged borders and abundant central neoepithelialization on the right palmar surface (Figure 1). No gross motor or sensory defects were identified. There was no epitrochlear, axillary, cervical, or supraclavicular lymphadenopathy. A shave biopsy of the plaque’s edge was performed, which demonstrated a hyperplastic epidermis comprising atypical poroid cells with frequent mitoses, scant necrosis, and regular ductal structures confined to the epidermis (Figure 2). Immunohistochemical profiling results were positive for anticytokeratin (CAM 5.2) and Ber-EP4 (Figure 3). When evaluated in aggregate, these findings were consistent with porocarcinoma in situ.

The patient was referred to a surgical oncologist for evaluation. At that time, an exophytic mass had developed in the central lesion. Although no lymphadenopathy was identified upon examination, the patient had developed tremoring and a contracture deformity of the right hand. Extensive imaging and urgent surgical resection were recommended, but the patient did not wish to pursue these options, opting instead to continue home remedies. At a 15-month follow-up via telephone, the patient reported that the home therapy had failed and he had moved back to Vietnam. Partial limb amputation had been recommended by a local provider. Unfortunately, the patient was subsequently lost to follow-up, and his current status is unknown.

Porocarcinomas are rare tumors, comprising just 0.005% to 0.01% of all cutaneous epithelial tumors.^1,2,5 They affect men and women equally, with an average age at diagnosis of 60 to 70 years.^1,2 At least half of all porocarcinomas develop de novo, while 18% to 50% arise from the degeneration of an existing poroma.^2,3 Exposure to UV light and immunosuppression, particularly following organ transplantation, represent 2 commonly suspected catalysts for this malignant transformation.⁴ De novo porocarcinomas are most causatively linked to localized trauma from burns or radiation exposure.⁵ Gene mutations in classic tumor suppressor genes—tumor protein p53 (TP53), phosphatase and tensin homolog (PTEN), rearranged during transfection (RET), adenomatous polyposis coli (APC)—and increased genetic heterogeneity follow these stimuli.⁶

The morphologic presentation of porocarcinoma is highly variable and may manifest as papules, nodules, or plaques in various states of erosion, ulceration, or excoriation. Diagnoses of basal and squamous cell carcinoma, primary adnexal tumors, seborrheic keratosis, pyogenic granuloma, and melanoma must all be considered and methodically ruled out.⁷ Porocarcinomas may arise nearly anywhere on the body, with a particular predilection for the lower extremities (35%), head/neck (24%), and upper extremities (14%).^3,4 Primary lesions arising from the extremities, genitalia, or buttocks herald a higher risk for lymphatic invasion and distant metastasis, while head and neck tumors more commonly remain localized.⁸ Bleeding, ulceration, or rapid expansion of a preexisting poroma is suggestive of malignant transformation and may portend a more aggressive disease pattern.^2,9

Unequivocal diagnosis relies on histological and immunohistochemical studies due to the marked clinical variance of this neoplasm.⁷ An irregular histologic pattern of poromatous basaloid cells with ductal differentiation and cytologic atypia commonly are seen with porocarcinomas.^2,8 Nuclear pleomorphism with cellular necrosis, increased mitotic figures, and abortive ductal formation with a distinct lack of retraction around cellular aggregates often are found. Immunohistochemical staining is needed to confirm the primary tumor diagnosis. Histochemical stains commonly employed include carcinoembryonic antigen (CEA), cytokeratin AE1/AE3, epithelial membrane antigen, p53, p63, Ki67, and periodic acid-Schiff.¹⁰ The use of BerEP4 has been reported as efficacious in highlighting sweat structures, which can be particularly useful in cases when basal cell carcinoma is not in the histologic differential.¹¹ These staining profiles afford confirmation of ductal differentiation with CEA, epithelial membrane antigen, and BerEP4, while p63 and Ki67 are used as surrogates for primary cutaneous neoplasia and cell proliferation, respectively.^5,11 Porocarcinoma lesions may be most sensitive to CEA and most specific to CK19 (a component of cytokeratin AE1/AE3), though these findings have not been widely reproduced.⁷

The treatment and prognosis of porocarcinoma vary widely. Surgically excised lesions recur in roughly 20% of cases, though these rates likely include tumors that were incompletely resected in the primary attempt. Although wide local excision with an average 1-cm margin remains the most employed removal technique, Mohs micrographic surgery may more effectively limit recurrence and metastasis of localized disease.^7,8,12 Metastatic disease foretells a mortality rate of at least 65%, which is problematic in that 10% to 20% of patients have metastatic disease at the time of diagnosis and another 20% will show metastasis following primary tumor excision.^8,10 Neoplasms with high mitotic rates and depths greater than 7 mm should prompt thorough diagnostic imaging, such as positron emission tomography or magnetic resonance imaging. A sentinel lymph node biopsy should be strongly considered and discussed with the patient.¹⁰ Treatment options for nodal and distant metastases include a combination of localized surgery, lymphadenectomy, radiotherapy, and chemotherapeutic agents.^2,4,5 The response to systemic treatment and radiotherapy often is quite poor, though the use of combinations of docetaxel, paclitaxel, cetuximab, and immunotherapy have been efficacious in smaller studies.^8,10 The highest rates of morbidity and mortality are seen in patients with metastases on presentation or with localized tumors in the groin and buttocks.⁸

The diagnosis of porocarcinoma may be elusive due to its relatively rare occurrence. Therefore, it is critical to consider this neoplasm in high-risk sites in older patients who present with an evolving nodule or tumor on an extremity. Routine histology and astute histochemical profiling are necessary to exclude diseases that mimic porocarcinoma. Once diagnosis is confirmed, management with prompt excision and diagnostic imaging is recommended, including a lymph node biopsy if appropriate. Due to its high metastatic potential and associated morbidity and mortality, patients with porocarcinoma should be followed closely by a multidisciplinary care team.

Brain disorders, including mental illness, neurologic conditions, and stroke, account for more than 15% of all health loss worldwide – more than either cardiovascular disease or cancer – at huge cost to health care systems and society, an analysis of data from the most recent Global Burden of Disease (GBD) study shows.

“The burden of brain conditions will increase as populations continue to grow and age,” said study presenter Shayla Smith, MPH, an epidemiologist at the Institute for Health Metrics and Evaluation, the University of Washington, Seattle, in a press release.

“By 2050, more than 50 million people will be aged 65-79,” she explained, adding that the COVID-19 pandemic “has also influenced the prevalence of mental disorders globally, as people were forced to isolate and social networks broke down.”

Other factors related to brain disorders, she noted, include education level, obesity, and smoking.

“There’s still research to be done on what is the most effective way to maintain brain health, but some literature suggests a healthy brain can be achieved through a healthy lifestyle of managing conditions such as high blood pressure and diabetes, limiting alcohol consumption and smoking, prioritizing sleep, eating healthy, and staying physically and mentally active,” said Ms. Smith.

The findings were presented at the annual meeting of the Congress of the European Academy of Neurology.
 

An ‘ambitious exercise’

Coinvestigator Xaviera Steele, also from the IHME, told press conference attendees that the institute was established at the University of Washington in 2007 with the aim of “standardizing the measurement of health outcomes around the world and for all health conditions.”

A central part of that is the GBD study, “which is a very ambitious exercise in descriptive epidemiology in an effort to systematically quantify health loss” due to disease, injury, and risk factors over time, stratified by country, region, age, and sex. In addition, researchers are mapping and projecting trends over the next century and are estimating disease expenditure by country, by type of expense, and by condition “to derive a health care access and quality score for each health system in the world,” Ms. Steele said.

They are also estimating exposure to risk factors, how those risk factors contribute to health burden, and associated health outcomes by race and ethnicity to reflect the “disparities that we know are very prevalent in countries such as the United States.” From that work, Ms. Steele said that brain health and related conditions “do emerge as one of the more pressing challenges of the 21st century.”
 

Increase in dementia, mental health conditions

The data, which were gathered from 200,000 sources by the IHME, indicate that the number of individuals aged 65 years or older will increase by 350% by 2100. Ms. Steele underlined that “policy action will be needed to help families, who will struggle to provide high-quality care for their loved ones with dementia at a reasonable cost.”

The IHME calculates that in Europe health care spending on Alzheimer’s disease will increase by 226% between 2015 and 2040.

Turning to other conditions, Ms. Steele showed that since 1990, the number of individuals living with anxiety in the European region has increased by 14%, while the number living with depressive disorders has gone up by 13%.

Worldwide, the figures are even starker. Depression is estimated to affect 300 million people across the globe, which represents a 71% increase since 1990. The number of strokes increased by 95% over the same period.

Nevertheless, the “impact of brain conditions such as stroke has decreased since the 1990s due to improved treatments available,” Ms. Smith noted in the press release.

To estimate the toll caused by brain conditions, including neurologic disorders, mental disorders, cerebrovascular disease, brain cancer, brain injuries, and select infectious conditions, the researchers calculated disability-adjusted life years (DALYs).

This, Ms. Smith explained in her presentation, “captures the morbidity and mortality associated with brain conditions” and is adjusted for patient location, age, and sex.

The investigators found that, globally, brain conditions accounted for more than 15% of all health loss in 2021, at 406 DALYs – more than the 206 million DALYs that were associated with cancer, and the 402 million that were linked to cardiovascular disease.

This health loss is associated with a $1.22 trillion loss in income for people living with health disorders worldwide and accounts for $1.14 trillion in direct health care costs.

The burden of mental disorders, neurologic conditions, and stroke is expected to increase dramatically between now and 2050, said Ms. Smith, who noted that health loss linked to brain conditions is higher in younger patients. This will create “new challenges for health systems, employers, patients, and families,” she said in the press release.

“Our goal is to see an improved prevention and treatment landscape for other brain conditions and reverse the growing health loss that we are currently forecasting.”
 

Worrying increase in stroke

Jurgita Valaikiene, MD, PhD, center of neurology, clinic of neurology and neurosurgery, Vilnius (Lithuania) University Faculty of Medicine, who chaired the session, was taken aback by the findings, particularly by the worldwide increase in stroke cases.

“I work in stroke,” she said, and “we spend a lot of time on the diagnosis of stroke” and its prevention. “We try to be faster, to catch asymptomatic stenosis in the neck or head, and to apply the best medical treatment to avoid a stroke. But despite that, the numbers are increasing. I understand the population is getting older ... but still it’s a huge number.”

Dr. Valaikiene pointed out that stroke is not necessarily a condition of aging, insofar as increasing age “is not related directly to stenosis in the neck. “For example, we can have healthier vessels in older age and unhealthy vessels, with high-grade stenosis, in someone aged 30 or 40 years.”

“There are a lot of risk factors, such as smoking, physical activity, and so on. It depends on the individual,” she added.

The study was funded by the Institute for Health Metrics and Evaluation at the University of Washington. The authors have disclosed no relevant financial relationships.

Brain disorders, including mental illness, neurologic conditions, and stroke, account for more than 15% of all health loss worldwide – more than either cardiovascular disease or cancer – at huge cost to health care systems and society, an analysis of data from the most recent Global Burden of Disease (GBD) study shows.

“The burden of brain conditions will increase as populations continue to grow and age,” said study presenter Shayla Smith, MPH, an epidemiologist at the Institute for Health Metrics and Evaluation, the University of Washington, Seattle, in a press release.

“By 2050, more than 50 million people will be aged 65-79,” she explained, adding that the COVID-19 pandemic “has also influenced the prevalence of mental disorders globally, as people were forced to isolate and social networks broke down.”

Other factors related to brain disorders, she noted, include education level, obesity, and smoking.

“There’s still research to be done on what is the most effective way to maintain brain health, but some literature suggests a healthy brain can be achieved through a healthy lifestyle of managing conditions such as high blood pressure and diabetes, limiting alcohol consumption and smoking, prioritizing sleep, eating healthy, and staying physically and mentally active,” said Ms. Smith.

The findings were presented at the annual meeting of the Congress of the European Academy of Neurology.
 

An ‘ambitious exercise’

Coinvestigator Xaviera Steele, also from the IHME, told press conference attendees that the institute was established at the University of Washington in 2007 with the aim of “standardizing the measurement of health outcomes around the world and for all health conditions.”

A central part of that is the GBD study, “which is a very ambitious exercise in descriptive epidemiology in an effort to systematically quantify health loss” due to disease, injury, and risk factors over time, stratified by country, region, age, and sex. In addition, researchers are mapping and projecting trends over the next century and are estimating disease expenditure by country, by type of expense, and by condition “to derive a health care access and quality score for each health system in the world,” Ms. Steele said.

They are also estimating exposure to risk factors, how those risk factors contribute to health burden, and associated health outcomes by race and ethnicity to reflect the “disparities that we know are very prevalent in countries such as the United States.” From that work, Ms. Steele said that brain health and related conditions “do emerge as one of the more pressing challenges of the 21st century.”

In the decade since safe, curative oral treatments were approved for treating hepatitis C virus (HCV) infections, only one in three U.S. patients diagnosed with the disease have been cleared of it, according to new data from the Centers for Disease Control and Prevention.

The findings indicate that current progress falls far short of the goal of the Viral Hepatitis National Strategic Plan for the United States, which calls for eliminating HCV for at least 80% of patients with the virus by 2030.

Lead author Carolyn Wester, MD, with the CDC’s Division of Viral Hepatitis, called the low numbers “stunning” and said that the researchers found that patients face barriers to being cured at every step of the way, from being diagnosed to accessing breakthrough direct-acting antiviral (DAA) agents.

The article was published online in the CDC’s Morbidity and Mortality Weekly Report.
 

Outcomes vary by age and insurance

Using longitudinal data from Quest Diagnostics laboratories, the researchers identified 1.7 million people who had a history of HCV infection from Jan. 1, 2013, to Dec. 31, 2022.

Of those patients, 1.5 million (88%) were categorized as having undergone viral testing.

Among those who underwent such testing, 1 million (69%) were categorized as having an initial infection. Just 356,807 patients with initial infection (34%) were cured or cleared of HCV. Of those found to be cured or cleared, 23,518 (7%) were found to have persistent infection or reinfection.

Viral clearance varied greatly by insurance. While 45% of the people covered under Medicare experienced viral clearance, only 23% of the uninsured and 31% of those on Medicaid did so.

Age also played a role in viral clearance. It was highest (42%) among those aged 60 and older. Clearance was lowest (24%) among patients in the 20-39 age group, the group most likely to be newly infected in light of the surge in HCV cases because of the opioid epidemic, Dr. Wester said. Persistent infection or reinfection was also highest in the 20-39 age group.

With respect to age and insurance type combined, the highest HCV clearance rate (49%) was for patients aged 60 and older who had commercial insurance; the lowest (16%) was for uninsured patients in the 20-39 age group.

The investigators evaluated people who had been diagnosed with HCV, Dr. Wester said. “It’s estimated about 40% of people in the U.S. are unaware of their infection.” Because of this, the numbers reported in the study may vastly underestimate the true picture, she told this news organization.
 

Barriers to treatment ‘insurmountable’ without major transformation

Increased access to diagnosis, treatment, and prevention services for persons with or at risk for acquiring hepatitis C needs to be addressed to prevent progression of disease and ongoing transmission and to achieve national hepatitis C elimination goals, the authors wrote.

The biggest barriers to improving HCV clearance are the high cost of treatment, widely varying insurance coverage, insurer restrictions, and challenges in diagnosing the disease, Dr. Wester added.

Overcoming these barriers requires implementation of universal HCV screening recommendations, including HCV RNA testing for all persons with reactive HCV antibody results, provision of treatment for all persons regardless of payer, and prevention services for persons at risk for acquiring new HCV infection, the authors concluded.

“The current barriers are insurmountable without a major transformation in our nation’s response,” Dr. Wester noted.

She expressed her support of the National Hepatitis C Elimination Program, offered as part of the Biden Administration’s 2024 budget proposal. She said that the initiative “is what we need to prevent the needless suffering from hepatitis C and to potentially save not only tens of thousands of lives but tens of billions of health care dollars.”

The three-part proposal includes a national subscription model to purchase DAA agents for those most underserved: Medicaid beneficiaries, incarcerated people, the uninsured, and American Indian and Alaska Native individuals treated through the Indian Health Service.

Under this model, the federal government would negotiate with manufacturers to buy as much treatment as needed for all individuals in the underserved groups.
 

What can physicians do?

Physicians can help improve HCV treatment and outcomes by being aware of the current testing guidelines, Dr. Wester said.

Guidelines now call for hepatitis C screening at least once in a lifetime for all adults, except in settings where the prevalence of HCV infection is less than 0.1%. They also call for screening during each pregnancy, with the same regional-prevalence exception.

Recommendations include curative treatment “for nearly everybody who is living with hepatitis C,” Dr. Wester added.

These CDC guidelines came out in April 2020, a time when the medical focus shifted to COVID-19, and that may have hurt awareness, she noted.

Physicians can also help by fighting back against non–evidence-based reasons insurance companies give for restricting coverage, Dr. Wester said.

Those restrictions include requiring specialists to prescribe DAA agents instead of allowing primary care physicians to do so, as well as requiring patients to have advanced liver disease or requiring patients to demonstrate sobriety or prove they are receiving counseling prior to their being eligible for treatment, Dr. Wester said.
 

Prior authorization a problem

Stacey B. Trooskin MD, PhD, MPH, assistant professor of medicine at the University of Pennsylvania in Philadelphia, told this news organization that prior authorization has been a major barrier for obtaining medications. Prior authorization requirements differ by state.

The paperwork must be submitted by already-stretched physician offices, and appeals are common. In that time, the window for keeping patients with HCV in the health care system may be lost, said Dr. Trooskin, chief medical adviser to the National Viral Hepatitis Roundtable.

“We know that about half of all Medicaid programs have removed prior authorization for most patients entirely,” she said, “but there are still half that require prior authorization.”

Action at the federal level is also needed, Dr. Trooskin said.

The countries that are successfully eliminating HCV and have successfully deployed the lifesaving medications provide governmental support for meeting patients where they are, she added.

Support can include inpatient and outpatient substance use disorder treatment programs or support in mental health settings, she noted.

“It’s not enough to want patients to come into their primary care provider and for that primary care provider to screen them,” Dr. Trooskin said. “This is about creating health care infrastructure so that we are finding patients at greatest risk for hepatitis C and integrating hepatitis C treatment into the services they are already accessing.”

Coauthor Harvey W. Kaufman, MD, is an employee of and owns stock in Quest Diagnostics. Coauthor William A. Meyer III, PhD, is a consultant to Quest Diagnostics. No other potential conflicts of interest were disclosed. Dr. Trooskin oversees C-Change, a hepatitis C elimination program, which receives funding from Gilead Sciences.

Support can include inpatient and outpatient substance use disorder treatment programs or support in mental health settings, she noted.

“It’s not enough to want patients to come into their primary care provider and for that primary care provider to screen them,” Dr. Trooskin said. “This is about creating health care infrastructure so that we are finding patients at greatest risk for hepatitis C and integrating hepatitis C treatment into the services they are already accessing.”

Like many stressful chronic conditions, hearing loss appears to foster fatigue, according to an analysis of National Health and Nutrition Examination Study data published in JAMA Otolaryngology – Head & Neck Surgery.

Researchers at Johns Hopkins University, Baltimore, examined NHANES data from 2015 to 2016 and 2017 to 2018, including findings on more than 3,000 participants aged 40 and older. Based on the audiometry subset of NHANES data, hearing loss was associated with a higher frequency of fatigue – even after adjustment for demographics, comorbidities, and lifestyle variables such as smoking, alcohol, and body mass index, in a nationally representative sample of adults in middle and older age.

“We wanted to get away from small clinical data and take a look at the population level to see if hearing loss was related to fatigue and, further perhaps, to cognitive decline,” said coauthor Nicholas S. Reed, AuD, PhD, an assistant professor of epidemiology at Johns Hopkins University, Baltimore, in an interview. “We found people with hearing loss had twice the risk of reporting fatigue nearly every day versus those not reporting fatigue.” This cross-sectional study provides needed population-based evidence from a nationally representative sample, according to Dr. Reed and associates, who have been researching the possible connection between age-related hearing loss, physical activity levels, and cognitive decline.
 

Study details

The 3,031 age-eligible participants had a mean age of 58 years; 48% were male, and 10% were Black. Some hearing loss was reported by 24%.

They responded to the following question: “Over the last 2 weeks, how often have you been bothered by feeling tired or having little energy?” Response categories were “not at all,” “several days,” “more than half the days,” and “nearly every day.” Those with hearing loss were more likely to report fatigue for more than half the days (relative risk ratio, 2.16; 95% confidence interval, 1.27-3.67) and nearly every day (RRR, 2.05; 95% CI, 1.16-3.65), compared with not having fatigue. Additional adjustment for comorbidities and depressive symptoms showed similar results.

Hearing loss was defined as > 25 decibels hearing level (dB HL) versus normal hearing of ≤ 25 dB HL, and continuously by every 10 dB HL poorer. Each 10-dB HL of audiometric hearing loss was associated with a higher likelihood of reporting fatigue nearly every day (RRR, 1.24; 95% CI,1.04-1.47), but not for more than half the days.

The association tended to be stronger in younger, non-Hispanic White, and female participants, but statistical testing did not support differential associations by age, sex, race, or ethnicity.

While some might intuitively expect hearing loss to cause noticeably more fatigue in middle-aged people who may be straining to hear during hours in the daily workplace or at home, Dr. Reed said older people probably feel more hearing-related fatigue owing to age and comorbidities. “And higher physical activity levels of middle-aged adults can be protective.”

Dr. Reed advised primary care physicians to be sure to ask about fatigue and hearing status during wellness exams and take appropriate steps to diagnose and correct hearing problems. “Make sure hearing is part of the health equation because hearing loss can be part of the culprit. And it’s very possible that hearing loss is also contributing to cognitive decline.”

Dr. Reed’s group will soon release data on a clinical trial on hearing loss and cognitive decline.

The authors called for studies incorporating fatigue assessments in order to clarify how hearing loss might contribute to physical and mental fatigue and how it could be associated with downstream outcomes such as fatigue-related physical impairment. Dr. Reed reported grants from the National Institute on Aging during the conduct of the study and stock compensation from the Neosensory Advisory Board outside of the submitted work. Several coauthors reported academic or government research funding as well as fees and honoraria from various private-sector companies.
