DENVER – Headaches, including tension-type, migraine, and posttraumatic, are robustly associated with both attempted and completed suicide, results of a large study suggest. 

The risk for suicide attempt was four times higher in people with trigeminal and autonomic cephalalgias (TAC), and the risk for completed suicide was double among those with posttraumatic headache compared with individuals with no headache.

The retrospective analysis included data on more than 100,000 headache patients from a Danish registry. 

“The results suggest there’s a unique risk among headache patients for attempted and completed suicide,” lead investigator Holly Elser, MD, MPH, PhD, resident, Department of Neurology, University of Pennsylvania, Philadelphia, said at the 2024 annual meeting of the American Academy of Neurology, where the findings were presented. “This really underscores the potential importance of complementary psychiatric evaluation and treatment for individuals diagnosed with headache.”
 

Underestimated Problem

Headache disorders affect about half of working-age adults and are among the leading causes of productivity loss, absence from work, and disability. 

Prior research suggests headache disorders often co-occur with psychiatric illness including depression, anxiety, posttraumatic stress disorder, and even attempted suicide.

However, previous studies that showed an increased risk for attempted suicide in patients with headache relied heavily on survey data and mostly focused on patients with migraine. There was little information on other headache types and on the risk for completed suicide.

Researchers used Danish registries to identify 64,057 patients with migraine, 40,160 with tension-type headache (TTH), 5743 with TAC, and 4253 with posttraumatic headache, all diagnosed from 1995 to 2019.

Some 5.8% of those with migraine, 6.3% with TAC, 7.2% with TTH, and 7.2% with posttraumatic headache, had a mood disorder (depression and anxiety combined) at baseline.

Those without a headache diagnosis were matched 5:1 to those with a headache diagnosis by sex and birth year.

Across all headache disorders, baseline prevalence of mood disorder was higher among those with headache versus population-matched controls. Dr. Elser emphasized that these are people diagnosed with a mood disorder in the inpatient, emergency department, or outpatient specialist clinic setting, “which means we are almost certainly underestimating the true burden of mood symptoms in our cohort,” she said.

Researchers identified attempted suicides using diagnostic codes. For completed suicide, they determined whether those who attempted suicide died within 30 days of the attempt.

For each headache type, investigators examined both the absolute and relative risk for attempted and completed suicides and estimated the risk at intervals of 5, 10, and 20 years after initial headache diagnosis.
 

Robust Link

The “power of this study is that we asked a simple, but important question, and answered it with simple, but appropriate, methodologic techniques,” Dr. Elser said.

The estimated risk differences (RDs) for attempted suicide were strongest for TAC and posttraumatic headache and for longer follow-ups. The RDs for completed suicide were largely the same but of a smaller magnitude and were “relatively less precise,” reflecting the “rarity of this outcome,” said Dr. Elser.

After adjusting for sex, age, education, income, comorbidities, and baseline medical and psychiatric diagnoses, researchers found the strongest association or attempted suicide was among those with TAC (adjusted hazard ratio [aHR], 4.25; 95% CI, 2.85-6.33).

“A hazard ratio of 4 is enormous” for this type of comparison, Dr. Elser noted.

For completed suicide, the strongest association was with posttraumatic headache (aHR, 2.19; 95% CI, 0.78-6.16).

The study revealed a robust association with attempted and completed suicide across all headache types, including TTH, noted Dr. Elser. The link between tension headaches and suicide “was the most striking finding to me because I think of that as sort of a benign and common headache disorder,” she said.

The was an observational study, so “it’s not clear whether headache is playing an etiological role in the relationship with suicide,” she said. “It’s possible there are common shared risk factors or confounders that explain the relationship in full or in part that aren’t accounted for in this study.”
 

Ask About Mood

The results underscore the need for psychiatric evaluations in patients with a headache disorder. “For me, this is just going to make me that much more likely to ask my patients about their mood when I see them in clinic,” Dr. Elser said.

After asking patients with headache about their mood and stress at home and at work, physicians should have a “low threshold to refer to a behavioral health provider,” she added.

Future research should aim to better understand the link between headache and suicide risk, with a focus on the mechanisms behind low- and high-risk subgroups, said Dr. Elser.

A limitation of the study was that headache diagnoses were based on inpatient, emergency department, and outpatient specialist visits but not on visits to primary care practitioners. The study didn’t include information on headache severity or frequency and included only people who sought treatment for their headaches.

Though it’s unlikely the results “are perfectly generalizable” with respect to other geographical or cultural contexts, “I don’t think this relationship is unique to Denmark based on the literature to date,” Dr. Elser said.

Commenting on the study, session co-chair Todd J. Schwedt, MD, professor of neurology, Mayo Clinic Arizona, Phoenix, and president-elect of the American Headache Society, noted that the study offers important findings “that demonstrate the enormous negative impact that headaches can exert.”

It’s “a strong reminder” that clinicians should assess the mental health of their patients with headaches and offer treatment when appropriate, he said.

The study received support from Aarhus University. No relevant conflicts of interest were reported.

DENVER — Seizure burden, defined by an artificial intelligence (AI) algorithm applied to point-of-care electroencephalography (POC EEG) recordings, can help predict functional outcomes.

After relevant cofactors were controlled for, higher seizure burden correlated with poorer functional outcomes. All of the patients in the study were being monitored as part of their standard of care owing to suspicion of seizures or because they were at risk for seizures, said study investigator Masoom Desai, MD, with the Department of Neurology, University of New Mexico, Albuquerque. The results were “compelling,” she said.

“Our study addresses the critical need for automation in monitoring epileptic activity and seizure burden,” Dr. Desai added during a press briefing at the 2024 annual meeting of the American Academy of Neurology (AAN).
 

A Pivotal Shift 

“Several decades of research have highlighted the significant correlation between seizure burden and unfavorable outcomes both in adult and pediatric populations,” said Dr. Desai. 

However, the traditional method of manually interpreting EEGs to identify seizures and their associated burden is a “complex and time-consuming process that can be subject to human error and variability,” she noted.

POC EEG is a rapid-access, reduced-montage EEG system that, when paired with an automated machine learning tool called Clarity (Ceribell, Inc; Sunnyvale, CA), can monitor and analyze seizure burden in real time.

The algorithm incorporates a comprehensive list of EEG features that have been associated with outcomes. It analyzes EEG activity every 10 seconds from all EEG channels and calculates a seizure burden in the past 5 minutes for the patient. The higher the seizure burden, the more time the patient has spent in seizure activity. 

Among 344 people with POC EEG (mean age, 62 years, 45% women) in the SAFER-EEG trial, 178 (52%) had seizure burden of zero throughout the recording and 41 (12%) had suspected status epilepticus (maximum seizure burden ≥ 90%). 

Before adjustment for clinical covariates, there was a significant association between high seizure burden and unfavorable outcomes. 

Specifically, 76% of patients with a seizure burden of 50% or greater had an unfavorable modified Rankin Scale score of 4 or greater at discharge and a similar proportion was discharged to long-term care facilities, she noted. 

After adjustment for relevant clinical covariants, patients with a high seizure burden (≥ 50 or > 90%) had a fourfold increase in odds of an unfavorable modified Rankin Scale score compared with those with no seizure burden. 

High seizure burden present in the last quarter of the recording was particularly indicative of unfavorable outcomes (fivefold increased odds), “suggesting the critical timing of seizures and its impact on patient prognosis,” Dr. Desai noted. 
 

‘Profound Implications’

“The implications of our research are profound, indicating a pivotal shift towards integrating AI and machine learning-guided automated EEG interpretation in management of critically ill patients with seizures,” she added. 

“As we move forward, our research will concentrate on applying this advanced tool in clinical decision making in clinical practice, examining how it can steer treatment decisions for patients, with the ultimate goal of enhancing patient care and improving outcomes for those affected by these neurological challenges,” Dr. Desai said. 

Briefing moderator Paul M. George, MD, PhD, chair of the AAN science committee, noted that this abstract was one of three featured at the “top science” press briefing themed “advancing the limits of neurologic care,” because it represents an “innovative method” of using new technology to improve understanding of neurologic conditions.

Dr. George said this technology “could be particularly useful in settings with few clinical specialists. It will be exciting to see as this unfolds, where it can guide maybe the ED doctor or primary care physician to help improve patient care.”

On that note, Dr. George cautioned that it’s still “early in the field” of using AI to guide decision-making and it will be important to gather more information to confirm that “machine learning algorithms can help guide physicians in treating patients with neurologic conditions.”

Funding for the study was provided by the University of Wisconsin-Madison and Ceribell, Inc. Dr. Desai received funding from Ceribell for this project. Dr. George has no relevant disclosures.

Physician practice ownership by corporations, including health insurers, private equity firms, and large pharmacy chains, reached 30.1% as of January for the first time surpassing ownership by hospitals and health systems (28.4%), according to a new report.

As a result, about three in five physician practices are now owned by nonphysicians.

In early 2020, corporations owned just about 17% of US medical practices, while hospitals and health systems owned about 25%, according to the report released Thursday by nonprofit Physician Advocacy Institute (PAI). But corporate ownership of medical groups surged during the pandemic.

These trends raise questions about how best to protect patients and physicians in a changing employment landscape, said Kelly Kenney, PAI’s chief executive officer, in a statement.

“Corporate entities are assuming control of physician practices and changing the face of medicine in the United States with little to no scrutiny from regulators,” Ms. Kenney said.

The research, conducted by consulting group Avalere for PAI, used the IQVIA OneKey database that contains physician and practice location information on hospital and health system ownership.

By 2022-2023, there was a 7.3% increase in the percentage of practices owned by hospitals and 5.9% increase in the percentage of physicians employed by these organizations, PAI said. In the same time frame, there was an 11% increase in the percentage of practices owned by corporations and a 3.0% increase in the percentage of physicians employed by these entities.

“Physicians have an ethical responsibility to their patients’ health,” Ms. Kenney said. “Corporate entities have a fiduciary responsibility to their shareholders and are motivated to put profits first…these interests can conflict with providing the best medical care to patients.”
 

Federal Scrutiny Increases

However, both federal and state regulators are paying more attention to what happens to patients and physicians when corporations acquire practices.

“Given recent trends, we are concerned that some transactions may generate profits for those firms at the expense of patients’ health, workers’ safety, quality of care, and affordable healthcare for patients and taxpayers,” said the Federal Trade Commission (FTC) and the Justice (DOJ) and Health and Human Services (HHS) departments.

This statement appears in those agencies’ joint request for information (RFI) announced in March. An RFI is a tool that federal agencies can use to gauge the level of both support and opposition they would face if they were to try to change policies. Public comments are due May 6.

Corporations and advocacy groups often submit detailed comments outlining reasons why the federal government should or should not act on an issue. But individuals also can make their case in this forum.

The FTC, DOJ, and HHS are looking broadly at consolidation in healthcare, but they also spell out potential concerns related to acquisition of physician practices.

For example, they asked clinicians and support staff to provide feedback about whether acquisitions lead to changes in:

• Take-home pay
• Staffing levels
• Workplace safety
• Compensation model (eg, from fixed salary to volume based)
• Policies regarding patient referrals
• Mix of patients
• The volume of patients
• The way providers practice medicine (eg, incentives, prescribing decisions, forced protocols, restrictions on time spent with patients, or mandatory coding practices)
• Administrative or managerial organization (eg, transition to a management services organization).

This statement appears in those agencies’ joint request for information (RFI) announced in March. An RFI is a tool that federal agencies can use to gauge the level of both support and opposition they would face if they were to try to change policies. Public comments are due May 6.

Corporations and advocacy groups often submit detailed comments outlining reasons why the federal government should or should not act on an issue. But individuals also can make their case in this forum.

The FTC, DOJ, and HHS are looking broadly at consolidation in healthcare, but they also spell out potential concerns related to acquisition of physician practices.

For example, they asked clinicians and support staff to provide feedback about whether acquisitions lead to changes in:

• Take-home pay
• Staffing levels
• Workplace safety
• Compensation model (eg, from fixed salary to volume based)
• Policies regarding patient referrals
• Mix of patients
• The volume of patients
• The way providers practice medicine (eg, incentives, prescribing decisions, forced protocols, restrictions on time spent with patients, or mandatory coding practices)
• Administrative or managerial organization (eg, transition to a management services organization).

Physician practice ownership by corporations, including health insurers, private equity firms, and large pharmacy chains, reached 30.1% as of January for the first time surpassing ownership by hospitals and health systems (28.4%), according to a new report.

As a result, about three in five physician practices are now owned by nonphysicians.

In early 2020, corporations owned just about 17% of US medical practices, while hospitals and health systems owned about 25%, according to the report released Thursday by nonprofit Physician Advocacy Institute (PAI). But corporate ownership of medical groups surged during the pandemic.

These trends raise questions about how best to protect patients and physicians in a changing employment landscape, said Kelly Kenney, PAI’s chief executive officer, in a statement.

“Corporate entities are assuming control of physician practices and changing the face of medicine in the United States with little to no scrutiny from regulators,” Ms. Kenney said.

The research, conducted by consulting group Avalere for PAI, used the IQVIA OneKey database that contains physician and practice location information on hospital and health system ownership.

By 2022-2023, there was a 7.3% increase in the percentage of practices owned by hospitals and 5.9% increase in the percentage of physicians employed by these organizations, PAI said. In the same time frame, there was an 11% increase in the percentage of practices owned by corporations and a 3.0% increase in the percentage of physicians employed by these entities.

“Physicians have an ethical responsibility to their patients’ health,” Ms. Kenney said. “Corporate entities have a fiduciary responsibility to their shareholders and are motivated to put profits first…these interests can conflict with providing the best medical care to patients.”

Key clinical point: In older men with early-stage, node-negative, hormone receptor-positive (HR+) breast cancer (BC), only radiation therapy (RT) or only hormone therapy (HT) did not confer overall survival (OS) benefits; however, HT + RT improved OS outcomes significantly.

Major finding: Compared with HT alone, OS outcomes improved significantly with HT + RT (adjusted hazard ratio [aHR] 0.641; P = .042) but not with RT alone (aHR 1.264; P = .420). The adjusted 5-year OS rates with HT, RT, and HT + RT were 84.0% (95% CI 77.1%-91.5%), 81.1% (95% CI 71.1%-92.5%), and 93.0% (95% CI 90.0%-96.2%), respectively.

Study details: This retrospective analysis of data from the National Cancer Database included 523 men and 188,683 matched women (age ≥ 65 years) with early-stage, node-negative, HR+ BC who underwent breast-conserving surgery and received HT alone, RT alone, or HT+RT.

Disclosures: This study received open access funding from the Statewide California Electronic Library Consortium. The authors declared no conflicts of interest.

Key clinical point: In premenopausal women with hormone receptor-positive (HR+) breast cancer (BC), treatment with ovarian function suppression (OFS) plus tamoxifen or OFS plus an aromatase inhibitor did not reduce the risk for recurrence compared with only tamoxifen therapy.

Major finding: Compared with tamoxifen alone, aromatase inhibitor + OFS (hazard ratio  0.76; 95% CI 0.38-1.33) or tamoxifen  + OFS (hazard ratio 0.87; 95% CI 0.50-1.45) did not significantly reduce the 5-year recurrence risk. However, the 5-year recurrence risk was reduced by 31% in patients who received tamoxifen or aromatase inhibitor combined with OFS for 2 years or more vs less than 2 years (hazard ratio 0.69; 95% CI 0.54-0.90).

Study details: Findings are from a population-based, retrospective cohort study including 2647 premenopausal women with resected HR+ BC who initiated tamoxifen alone (n = 2260), tamoxifen + OFS (n = 232), or aromatase inhibitor + OFS (n = 155).

Key clinical point: Among patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2−) breast cancer (BC), adjuvant chemotherapy failed to improve survival outcomes in older women (age ≥ 80 years) but improved prognosis in women age 65-79 years.

Major finding: Adjuvant chemotherapy did not significantly improve overall survival (OS; P = .79) and cancer-specific survival (CSS; P = .091) outcomes in patients age 80 years and older. However, in patients age 65-79 years, adjuvant chemotherapy was effective in improving OS (P < .001) but not CSS (P = .092).

Study details: This retrospective cohort study included 45,762 women with HR+/HER2− BC, age 65-79 years (n = 38,128) or 80 years and older (n = 7634) from the Surveillance, Epidemiology, and End Results (SEER) database, of whom 20.7% and 3.8%, respectively, received adjuvant chemotherapy.

Key clinical point: Exposure to antibiotics during neoadjuvant pembrolizumab treatment was associated with a high residual cancer burden (RCB) in patients with human epidermal growth factor receptor 2-negative (HER2−), stage II or III breast cancer (BC).

Major finding: During pembrolizumab treatment, antibiotic use was significantly correlated with RCB index (RCB index-coefficient 0.86; P = .01) and was associated with a higher mean RCB index compared with no use of antibiotics (1.80 vs 1.08).

Study details: This secondary analysis of the phase 2 I-SPY2 trial included 66 patients with HER2− stage II or III BC treated with pembrolizumab plus paclitaxel followed by doxorubicin plus cyclophosphamide, of which 27% of patients concurrently used antibiotics.

Key clinical point: MRI response can be used to identify patients with hormone receptor-negative (HR−), human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC) who may only require three cycles of neoadjuvant chemotherapy to achieve pathological complete response (pCR).

Major finding: After one to three cycles of chemotherapy, nearly one third of patients with HR−/HER2+ BC achieved radiological complete response (36%; 95% CI 30%-43%), of whom the majority of patients achieved pCR (88%; 95% CI 79%-94%). No treatment-related deaths were reported.

Study details: This phase 2 TRAIN-3 trial included 235 and 232 patients with stages II-III HR−/HER2+ and HR+/HER2+ BC, respectively, who received neoadjuvant chemotherapy once every 3 weeks for up to nine cycles and whose response was monitored using breast MRI after every three cycles and lymph node biopsy.

Key clinical point: In patients with breast cancer (BC), premastectomy radiotherapy (PreMRT) followed by mastectomy and immediate breast reconstruction (IMBR) is feasible, safe, and shortens the time required for breast reconstruction.

Major finding: At a median follow-up of 29.7 months, there were no complete flap losses, locoregional recurrences, distant metastases, or deaths in the 48 patients who completed mastectomy with IMBR. Patients could undergo mastectomy with IMBR as early as 3 weeks (median 23 days) after completing radiotherapy. No grade 3-4 radiotherapy-related toxic effect or discontinuation of radiotherapy was reported.

Study details: The study enrolled 49 patients with T0-T3, N0-N3b, M0 BC from the phase 2 SAPHIRE trial who received PreMRT and were randomly assigned to receive hypofractionated or conventionally fractionated regional nodal irradiation, followed by mastectomy and IMBR.

Disclosures: This study was supported by the National Cancer Institute of the US National Institutes of Health and others. Five authors declared receiving grants from or having other ties with various sources.

Key clinical point: In patients with breast cancer (BC), premastectomy radiotherapy (PreMRT) followed by mastectomy and immediate breast reconstruction (IMBR) is feasible, safe, and shortens the time required for breast reconstruction.

Major finding: At a median follow-up of 29.7 months, there were no complete flap losses, locoregional recurrences, distant metastases, or deaths in the 48 patients who completed mastectomy with IMBR. Patients could undergo mastectomy with IMBR as early as 3 weeks (median 23 days) after completing radiotherapy. No grade 3-4 radiotherapy-related toxic effect or discontinuation of radiotherapy was reported.
