Key clinical point: Patients with chronic migraine have autonomic dysfunction, the extent of which is evaluated using heart rate variability (HRV) analysis, and a preserved function is associated with a superior response to flunarizine preventive treatment.

Major finding: Most heart-rate variability (HRV) parameters, except the ratios of low-frequency (LF) band and LF/high-frequency band, were significantly lower in patients with migraine vs control individuals (P < .001). The response to flunarizine treatment was superior in patients with normal HRV, as exemplified by higher reductions in monthly headache days after 3 months in those with normal vs lower HRV (─9.7 days vs ─6.2 days; P = .026).

Study details: This cross-sectional, prospective study included 81 prophylaxis-naive patients with chronic migraine and 58 age- and gender-matched control individuals. Patients with migraine initiated flunarizine as a preventive treatment for 12 weeks.

Disclosures: This study was supported by grants from the National Science and Technology Council, Taiwan, and others. SJ Wang declared being a principal investigator and receiving personal fees as an advisor or speaker from various sources.

Key clinical point: This study provides class-III real-world evidence that anti-calcitonin gene-related peptide (anti-CGRP) monoclonal antibodies (mAb) are efficacious and safe in patients with migraine age > 65 years but may take more time to show effect in these patients vs those age < 55 years.

Major finding: A similar proportion of patients age > 65 years vs < 55 years achieved a 50% response rate at 20-24 weeks of initiating anti-CGRP mAb (P = .811). Patients age > 65 years vs < 55 years showed lesser reduction in mean monthly headache days at 10-12 weeks (P = .001) and higher reduction in mean monthly migraine days at 20-24 weeks (P = .04). Both groups had similar incidence of treatment-emergent adverse events.

Study details: This multicenter observational case-control study included 114 patients age > 65 years and 114 sex-matched patients age < 55 years with episodic or chronic migraine who received anti-CGRP mAb.

Key clinical point: Three different ketogenic diets (KD)—very-low-calorie ketogenic diet (VLCKD), low-glycemic-index diet (LGID), and 2:1 KD—improved migraine frequency, migraine intensity, and fatigue in patients with chronic and high-frequency episodic migraine.

Major finding: At 3 months, all three KD led to a significant reduction in the fatigue severity scale (FSS) scores, along with reductions in the frequency and intensity of migraine attacks, Migraine Disability Assessment Test (MIDAS) scores, and Headache Impact Test 6 (HIT-6) scores (all P < .001). The mean reduction in FSS had positive correlation with the mean reduction in MIDAS (r = 0.361; P = .002) and HIT-6 (r = 0.344; P = .001) scores.

Study details: This retrospective single-center pilot study included 76 patients with chronic or high-frequency episodic migraine who followed three different KD                                 (VLCKD, LGID, or 2:1 KD) for ≥3 months.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Breast cancer in young women presents a unique set of challenges owing to life-stage at the time of diagnosis and treatment. Oncofertility, family planning, and pregnancy are essential issues to address at the time of initial consultation and throughout the survivorship setting. Various studies have provided supportive evidence regarding the safety of pregnancy after breast cancer diagnosis and treatment.³ HR+ breast cancer is associated with its own distinctive considerations related to pregnancy and its timing, including the use of endocrine therapy for 5-10 years, the role of female hormones during pregnancy, and late patterns of recurrence that characterize this subtype. A meta-analysis including eight eligible studies and 3805 women with HR+ early breast cancer investigated the prognostic impact of future pregnancy among these patients (Arecco et al). A total of 1285 women had a pregnancy after breast cancer diagnosis and treatment; there was no difference in disease-free survival (hazard ratio 0.96; 95% CI 0.75-1.24; P = .781) and better overall survival (OS; hazard ratio 0.46; 95% CI 0.27-0.77; P < .005) in those with vs those without subsequent pregnancy. Added to this body of data is the prospective POSITIVE trial, which showed that a temporary pause of endocrine therapy for an attempt at conceiving appears to be safe in young women with early HR+ breast cancer with short-term follow-up.⁴ Future research efforts investigating outcomes after assisted reproductive technologies in this population, those with germline mutations, and extended follow-up of studies, such as POSITIVE, will continue to inform guidance for and management of young women with breast cancer.

Guidelines favor the use of adjuvant chemotherapy for small, node-negative, triple-negative breast cancer (TNBC), specifically T1b and T1c tumors.⁵ However, high-quality data to inform this decision-making are sparse, and it is valuable to consider the magnitude of benefit weighed against possible risks and side effects of treatment, as well as patient comorbidities. A retrospective analysis of the Surveillance, Epidemiology, and End Results (SEER) database including 11,510 patients (3388 with T1b and 8122 with T1c TNBC) evaluated the impact of adjuvant chemotherapy on OS and breast cancer–specific survival (BCSS) (Carbajal-Ochoa et al). The use of adjuvant chemotherapy was associated with improved OS (hazard ratio 0.54; 95% CI 0.47-0.62; P < .001) and BCSS (hazard ratio 0.79; 95% CI 0.63-0.99; P = .043) among T1c TNBC. For those with T1b tumors, adjuvant chemotherapy improved OS (hazard ratio 0.52; 95% CI 0.41-0.68; P < .001) but did not improve BCSS (hazard ratio 0.70; 95% CI 0.45-1.07; P = .10). A better understanding of the molecular drivers implicated in this heterogeneous subtype, and predictors of response and resistance, will aid in identifying those patients who have greater benefit and those who can potentially be spared chemotherapy-related toxicities.
