Does Antibiotic Use During Influenza Infection Worsen Lung Immunity?
TOPLINE:
Antibiotic use during influenza infection increases lung eosinophils, impairing immunity against secondary bacterial pneumonia. This study highlights the detrimental effects of antibiotics on lung health during viral infections.
METHODOLOGY:
- Researchers conducted a murine model study to evaluate the impact of antibiotic use during influenza infection on lung immunity. Mice were treated with a broad-spectrum antibiotic cocktail (vancomycin, neomycin, ampicillin, and metronidazole) starting 7 days before influenza infection.
- The study included intranasal infection with influenza virus followed by a secondary challenge with methicillin-resistant Staphylococcus aureus (MRSA).
- Finally, in sub-study, a total of three cohorts of hospitalized patients were evaluated to correlate eosinophil levels with antibiotic use, systemic inflammation, and outcomes.
TAKEAWAY:
- Antibiotic use during influenza infection impairs lung immunity, leading to increased lung eosinophils and reduced macrophage function.
- The study found that antibiotic treatment during influenza infection caused fungal dysbiosis, driving lung eosinophilia and impairing MRSA clearance.
- The detrimental effects of antibiotics on lung immunity were specific to the two-hit model of influenza followed by MRSA infection in mice.
- In hospitalized patients, eosinophil levels positively correlated with antibiotic use, systemic inflammation, and worsened outcomes.
IN PRACTICE:
“Our study highlights the pernicious effects of antibiotic use during viral infections and defines a mechanism whereby antibiotics perturb the gut mycobiome and result in lung eosinophilia. In turn, lung eosinophils, via release of MBP-1, suppress alveolar macrophage clearance of bacteria,” the authors of the study wrote.

This study was led by Marilia Sanches Santos Rizzo Zuttion, Cedars-Sinai Medical Center in Los Angeles. It was published online in The Journal of Clinical Investigation.
LIMITATIONS:
This study’s limitations included the use of a murine model, which may not fully replicate human immune responses. Additionally, the study focused on a specific antibiotic cocktail, and results may vary with different antibiotics. The findings were also specific to the two-hit model of influenza followed by MRSA infection, limiting generalizability to other infections.

Vitamin K Supplementation Reduces Nocturnal Leg Cramps in Older Adults
TOPLINE:
Vitamin K supplementation significantly reduced the frequency, intensity, and duration of nocturnal leg cramps in older adults. No adverse events related to vitamin K were identified.
METHODOLOGY:
- Researchers conducted a multicenter, double-blind, placebo-controlled randomized clinical trial in China from September 2022 to December 2023.
- A total of 199 participants aged ≥ 65 years with at least two documented episodes of nocturnal leg cramps during a 2-week screening period were included.
- Participants were randomized in a 1:1 ratio to receive either 180 μg of vitamin K (menaquinone 7) or a placebo daily for 8 weeks.
- The primary outcome was the mean number of nocturnal leg cramps per week, while secondary outcomes were the duration and severity of muscle cramps.
- The ethics committees of Third People’s Hospital of Chengdu and Affiliated Hospital of North Sichuan Medical College approved the study, and all participants provided written informed consent.
TAKEAWAY:
- Vitamin K group experienced a significant reduction in the mean weekly frequency of cramps (mean difference, 2.60 [SD, 0.81] to 0.96 [SD, 1.41]) compared with the placebo group, which maintained a mean weekly frequency of 3.63 (SD, 2.20) (P < .001).
- The severity of nocturnal leg cramps decreased more in the vitamin K group (mean difference, −2.55 [SD, 2.12] points) than in the placebo group (mean difference, −1.24 [SD, 1.16] points).
- The duration of nocturnal leg cramps also decreased more in the vitamin K group (mean difference, −0.90 [SD, 0.88] minutes) than in the placebo group (mean difference, −0.32 [SD, 0.78] minutes).
- No adverse events related to vitamin K use were identified, indicating a good safety profile for the supplementation.
IN PRACTICE:
“Given the generally benign characteristics of NLCs, treatment modality must be both effective and safe, thus minimizing the risk of iatrogenic harm,” the study authors wrote.
SOURCE:
This study was led by Jing Tan, MD, the Third People’s Hospital of Chengdu in Chengdu, China. It was published online on October 28 in JAMA Internal Medicine.
LIMITATIONS:
This study did not investigate the quality of life or sleep, which could have provided additional insights into the impact of vitamin K on nocturnal leg cramps. The relatively mild nature of nocturnal leg cramps experienced by the participants may limit the generalizability of the findings to populations with more severe symptoms.
DISCLOSURES:
This study was supported by grants from China Health Promotion Foundation and the Third People’s Hospital of Chengdu Scientific Research Project. Tan disclosed receiving personal fees from BeiGene, AbbVie, Pfizer, Xian Janssen Pharmaceutical, and Takeda Pharmaceutical outside the submitted work.

Postpartum Exercise Reduces Depression and Anxiety Symptoms
TOPLINE:
Postpartum exercise reduces the severity of depressive and anxiety symptoms. Initiating exercise within 12 weeks post partum is linked to greater reductions in depressive symptoms.
METHODOLOGY:
- Researchers conducted a systematic review and meta-analysis including 35 studies with a total of 4072 participants.
- The review included randomized controlled trials and nonrandomized interventions examining the impact of postpartum exercise on depression and anxiety.
- Participants were postpartum individuals within the first year after childbirth, with interventions including various types of exercise.
- Data sources included online databases with data up to January 2024, reference lists, and hand searches.
- The Grading of Recommendations, Assessment, Development, and Evaluation framework was used to assess the certainty of evidence.
TAKEAWAY:
- Postpartum exercise-only interventions resulted in a moderate reduction in the severity of depressive symptoms (standardized mean difference [SMD], –0.52; 95% CI, –0.80 to –0.24).
- Exercise-only interventions were associated with a small reduction in the severity of anxiety symptoms (SMD, –0.25; 95% CI, –0.43 to –0.08).
- Initiating exercise within 12 weeks post partum was associated with a greater reduction in depressive symptoms, compared with starting later.
- Postpartum exercise was associated with a 45% reduction in the odds of developing depression (odds ratio, 0.55; 95% CI, 0.32-0.95).
IN PRACTICE:
“Further investigation should aim to investigate the effects of postpartum exercise in individuals who experienced perinatal complications and in those who had limitations to exercise during pregnancy. Additionally, more investigation is required to address the possible lasting effects of postpartum exercise on maternal mental health as there were very limited studies reporting on this outcome,” the authors of the study wrote.
SOURCE:
This study was led by Margie H. Davenport, University of Alberta in Edmonton, Canada. It was published online in British Journal of Sports Medicine.
LIMITATIONS:
This study’s limitations included high heterogeneity among included studies, small sample sizes in some studies, and the combination of exercise with other interventions in some cases. These factors may have affected the generalizability and precision of the findings.
DISCLOSURES:
This study was funded by the Christenson Professorship in Active Healthy Living. Davenport is funded by a Christenson Professorship in Active Healthy Living. One coauthor is funded by the Université du Québec à Trois-Rivières research chair in physical activity and maternal and neonatal health. No relevant conflicts of interest were disclosed by the authors.

Telehealth Adoption in Primary Care: Reducing Low-Value Services
TOPLINE:
Increased telehealth use in primary care practices is associated with reduced rates of low-value cervical cancer screening and thyroid testing. No significant association is found between telehealth use and most other low-value care services.
METHODOLOGY:
- Researchers conducted a retrospective cohort study using Medicare fee-for-service claims data from January 1, 2019, to December 31, 2022.
- A total of 577,928 Medicare beneficiaries attributed to 2552 primary care practices in Michigan were included in the study.
- Telehealth use was stratified into low, medium, and high tertiles based on the number of telehealth services per 1000 beneficiaries in 2022.
- Low-value care was assessed using eight claims-based measures relevant to primary care, grouped into office-based, laboratory-based, imaging-based, and mixed-modality services.
- Poisson regression models were used to estimate the association between practice-level telehealth use and rates of low-value care services, controlling for practice-level characteristics.
TAKEAWAY:
- High practice-level telehealth use was associated with lower rates of low-value cervical cancer screening (–2.9 services per 1000 beneficiaries; 95% CI, –5.3 to –0.4).
- High practice-level telehealth use was associated with lower rates of low-value thyroid testing (–40 tests per 1000 beneficiaries; 95% CI, –70 to –9).
- No significant association was found between practice-level telehealth use and rates of other low-value care services.
- The findings suggested that telehealth can be used to deliver primary care services without introducing wasteful or unnecessary care and can even reduce low-value care.
IN PRACTICE:
“While the rapid growth of telehealth has enhanced access to care for individuals, it has also raised concern for unintended consequences in the form of wasteful or unnecessary care, ie, low-value care. Our study suggests that increased practice-level telehealth use was not associated with the delivery of low-value care services in primary care and may even help reduce office-based low-value care,” the authors of the study wrote.
SOURCE:
This study was led by Terrence Liu, MD, MS, University of Michigan, Ann Arbor. It was published online in JAMA Network Open.
LIMITATIONS:
This study was performed among Medicare fee-for-service beneficiaries with a Michigan residence and may not be generalizable to the broader Medicare beneficiary population. Administrative claims data do not include clinical information, which limited the ability to measure overall quality of care. The study defined telehealth use at the practice level and did not assess individual outcomes. Additional research is needed at a national level to determine the impact of telehealth on low-value care services in primary care.

Virtual Yoga Classes Improve Chronic Low Back Pain
TOPLINE:
Virtual yoga classes significantly reduced chronic low back pain intensity and improved back-related function in health system employees. Improvements were sustained at 24 weeks, with reduced pain medication use and better sleep quality.
METHODOLOGY:
- A single-blinded, 24-week, 2-arm, randomized clinical trial was conducted from May 3, 2022, through May 23, 2023, comparing live-streamed yoga classes with a wait-list control among adults with chronic low back pain.
- A total of 140 participants aged 18-64 years with chronic low back pain were recruited from the Cleveland Clinic Employee Health Plan.
- Inclusion criteria included a mean low back pain intensity score of at least 4 on an 11-point numerical rating scale and daily back pain interference about half or more of the days.
- The intervention consisted of 12 consecutive weekly, 60-minute, virtual, live-streamed hatha yoga group classes.
Coprimary outcomes were mean pain intensity in the previous week on the 11-point numerical rating scale and back-related function as assessed using the 23-point modified Roland Morris Disability Questionnaire at 12 weeks.
TAKEAWAY:
- Participants in the virtual yoga group showed greater reductions in mean pain intensity at 12 weeks (mean change, –1.5 points; P < .001) and 24 weeks (mean change, –2.3 points; P < .001) compared to the wait-list control group.
- Back-related function improved significantly in the virtual yoga group at 12 weeks (mean change, –2.8 points; P < .001) and 24 weeks (mean change, –4.6 points; P < .001), compared with the control group.
- Virtual yoga participants reported 21.2 percentage points less use of any analgesic medication during the past week at 24 weeks, compared with the control group.
- Sleep quality improved more in the virtual yoga group at 12 weeks (mean change, 0.4 points; P = .008) and 24 weeks (mean change, 0.4 points; P = .005), compared with the control group.
IN PRACTICE:
“Given the demonstrated noninferiority of yoga to physical therapy, structured virtual yoga programs and physical therapy are reasonable choices for patients with [chronic low back pain] depending on accessibility, cost, and patient preference. These findings support the call by the National Academy of Medicine for increased evidenced-based pain treatments that can be disseminated via technology-based platforms,” wrote the authors of the study.

The study was led by Hallie Tankha, PhD, Cleveland Clinic in Ohio. It was published online on November 1, 2024, in JAMA Network Open.
LIMITATIONS:
The study had a low adherence rate, with only 36.6% of participants attending at least 50% of the yoga classes. There was also a higher rate of missing data in the yoga group compared to the control group. The study did not include a longer-term follow-up assessment beyond 24 weeks.

Mepivacaine Reduces Pain During IUD Placement in Nulliparous Women
TOPLINE:
Mepivacaine instillation significantly reduced pain during intrauterine device (IUD) placement in nulliparous women. More than 90% of women in the intervention group reported tolerable pain compared with 80% of those in the placebo group.
METHODOLOGY:
- A multicenter, double-blind, randomized, placebo-controlled trial was conducted in 12 centers in Sweden, which involved 151 nulliparous women aged 18-31 years.
- Participants were randomly assigned to receive either 10 mL of 20 mg/mL mepivacaine or 10 mL of 0.9 mg/mL sodium chloride (placebo) through a hydrosonography catheter 2 minutes before IUD placement.
- Pain scores were measured using a 100-mm visual analog scale (VAS) at baseline, after instillation, during IUD placement, and 10 minutes post placement.
- The primary outcome was the difference in VAS pain scores during IUD placement between the intervention and placebo groups.
TAKEAWAY:
- Mepivacaine instillation resulted in a statistically significant reduction in mean VAS pain scores during IUD placement, with a mean difference of 13.3 mm (95% CI, 5.75-20.87; P < .001).
- After adjusting for provider impact, the mean VAS pain score difference remained significant at 12.2 mm (95% CI, 4.85-19.62; P < .001).
- A higher proportion of women in the mepivacaine group reported tolerable pain during IUD placement (93.3%) than the placebo group (80.3%; P = .021).
- No serious adverse effects were associated with mepivacaine instillation, and there were no cases of uterine perforation in either group.
IN PRACTICE:
“We argue that the pain reduction in our study is clinically important as a greater proportion of women in our intervention group, compared to the placebo group, reported tolerable pain during placement and to a higher extent rated the placement as easier than expected and expressed a willingness to choose IUD as contraception again,” the authors of the study wrote.
SOURCE:
This study was led by Niklas Envall, PhD; Karin Elgemark, MD; and Helena Kopp Kallner, MD, PhD, at the Department of Clinical Sciences, Danderyd Hospital, Karolinska Institutet in Stockholm, Sweden. It was published online in American Journal of Obstetrics & Gynecology.
LIMITATIONS:
This study’s limitations included the exclusive focus on one type of IUD (LNG-IUS 52 mg, 4.4 mm), which may limit generalizability to other IUD types. Additionally, only experienced providers participated, which may not reflect settings with less experienced providers. Factors such as anticipated pain and patient anxiety were not systematically assessed, potentially influencing pain perception.
DISCLOSURES:
Envall received personal fees from Bayer for educational activities and honorarium from Medsphere Corp USA for expert opinions on long-acting reversible contraception. Kallner received honoraria for consultancy work and lectures from multiple pharmaceutical companies, including AbbVie, Actavis, Bayer, and others. The study was funded by the Swedish Research Council. Additional disclosures are noted in the original article.

Contraceptive Users in the United States Show Preference for Alternative Sources
TOPLINE:
Individuals using contraceptive pills, patches, and rings must frequently interact with the healthcare system for continued use. More than half of US contraceptive users prefer alternative sources over traditional in-person care. Only 35.6% of respondents selected in-person care as their most preferred source.
METHODOLOGY:
- Researchers conducted a cross-sectional nationally representative survey in the United States in 2022 through NORC’s AmeriSpeak panel.
- A total of 3059 eligible panelists, aged 15-44 years, completed the survey, with 595 individuals currently using a pill, patch, or ring contraceptive included in the analysis.
- Primary outcomes measured were the use of any preferred source and the most preferred source when obtaining contraception.
- Sources included in-person care, telehealth, pharmacist-prescribed, online service, and over the counter.
- Data were analyzed from January 25, 2023, to August 15, 2024.
TAKEAWAY:
- Only 35.6% of respondents selected in-person care as their most preferred source of contraception.
- Only 49.7% of respondents obtained their method from a preferred source, while 39.8% received it from their most preferred source.
- Respondents who previously reported being unable to get their method on time had higher odds of preferring an alternative source (adjusted odds ratio [AOR], 2.57; 95% CI, 1.36-4.87).
- Those who recently received person-centered contraceptive counseling had lower odds of preferring an alternative source (AOR, 0.59; 95% CI, 0.35-0.98).
IN PRACTICE:
“The low level of preference for in-person care suggests that expanding contraceptive sources outside of traditional healthcare settings has a role in ameliorating barriers to access and can promote reproductive autonomy,” wrote the authors of the study.
SOURCE:
The study was led by Anu Manchikanti Gómez, PhD, Sexual Health and Reproductive Equity Program, School of Social Welfare, University of California, Berkeley. It was published online in JAMA Network Open.
LIMITATIONS:
The study’s cross-sectional design limited the ability to establish causality. The sample was limited to individuals aged 15-44 years, which may not represent all contraceptive users. Self-reported data may be subject to recall bias. The study did not distinguish between synchronous and asynchronous telehealth preferences.
DISCLOSURES:
The study was supported by Arnold Ventures. Gómez disclosed receiving personal fees from various organizations outside the submitted work. Additional disclosures are noted in the original article.

Higher Doses of Vitamin D3 Do Not Reduce Cardiac Biomarkers in Older Adults
TOPLINE:
Higher doses of vitamin D3 supplementation did not significantly reduce cardiac biomarkers in older adults with low serum vitamin D levels. The STURDY trial found no significant differences in high-sensitivity cardiac troponin I (hs-cTnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between low- and high-dose groups.
METHODOLOGY:
- A total of 688 participants aged 70 years or older with low serum 25-hydroxy vitamin D levels (10-29 ng/mL) were included in the STURDY trial.
- Participants were randomized to receive one of four doses of vitamin D3 supplementation: 200, 1000, 2000, or 4000 IU/d, with 200 IU/d as the reference dose.
- Cardiac biomarkers, including hs-cTnI and NT-proBNP, were measured at baseline, 3 months, 12 months, and 24 months.
- The trial was conducted at two community-based research institutions in the United States between July 2015 and March 2019.
- The effects of vitamin D3 dose on biomarkers were assessed via mixed-effects tobit models, with participants followed up to 24 months or until study termination.
TAKEAWAY:
- Higher doses of vitamin D3 supplementation did not significantly affect hs-cTnI levels compared with the low-dose group (1.6% difference; 95% CI, −5.3 to 8.9).
- No significant differences were observed in NT-proBNP levels between the high-dose and low-dose groups (−1.8% difference; 95% CI, −9.3 to 6.3).
- Both hs-cTnI and NT-proBNP levels increased in both low- and high-dose groups over time, with hs-cTnI increasing by 5.2% and 7.0%, respectively, and NT-proBNP increasing by 11.3% and 9.3%, respectively.
- The findings suggest that higher doses of vitamin D3 supplementation do not reduce markers of subclinical cardiovascular disease in older adults with low serum vitamin D levels.
IN PRACTICE:
“We can speculate that the systemic effects of vitamin D deficiency are more profound among the very old, and there may be an inverse relationship between supplementation and inflammation. It is also possible that serum vitamin D level is a risk marker but not a risk factor for CVD risk and related underlying mechanisms,” wrote the authors of the study.
SOURCE:
The study was led by Katharine W. Rainer, MD, Beth Israel Deaconess Medical Center in Boston. It was published online in the Journal of the American College of Cardiology.
LIMITATIONS:
The study’s community-based population may limit the generalizability of the findings to populations at higher risk for cardiovascular disease. Additionally, the baseline cardiac biomarkers were lower than those in some high-risk populations, which may affect the precision of the assay performance. The study may not have had adequate power for cross-sectional and subgroup analyses. Both groups received some vitamin D3 supplementation, making it difficult to determine the impact of lower-dose supplementation vs no supplementation.
DISCLOSURES:
The study was supported by grants from the National Institute on Aging, the Office of Dietary Supplements, the Mid-Atlantic Nutrition Obesity Research Center, and the Johns Hopkins Institute for Clinical and Translational Research. Rainer disclosed receiving grants from these organizations.

It is also possible that serum vitamin D level is a risk marker but not a risk factor for CVD risk and related underlying mechanisms,” wrote the authors of the study.
SOURCE:
The study was led by Katharine W. Rainer, MD, Beth Israel Deaconess Medical Center in Boston. It was published online in the Journal of the American College of Cardiology.
LIMITATIONS:
The study’s community-based population may limit the generalizability of the findings to populations at higher risk for cardiovascular disease. Additionally, the baseline cardiac biomarkers were lower than those in some high-risk populations, which may affect the precision of the assay performance. The study may not have had adequate power for cross-sectional and subgroup analyses. Both groups received some vitamin D3 supplementation, making it difficult to determine the impact of lower-dose supplementation vs no supplementation.
DISCLOSURES:
The study was supported by grants from the National Institute on Aging, the Office of Dietary Supplements, the Mid-Atlantic Nutrition Obesity Research Center, and the Johns Hopkins Institute for Clinical and Translational Research. Rainer disclosed receiving grants from these organizations.

TOPLINE:
Higher doses of vitamin D3 supplementation did not significantly reduce cardiac biomarkers in older adults with low serum vitamin D levels. The STURDY trial found no significant differences in high-sensitivity cardiac troponin I (hs-cTnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between low- and high-dose groups.
METHODOLOGY:
- A total of 688 participants aged 70 years or older with low serum 25-hydroxy vitamin D levels (10-29 ng/mL) were included in the STURDY trial.
- Participants were randomized to receive one of four doses of vitamin D3 supplementation: 200, 1000, 2000, or 4000 IU/d, with 200 IU/d as the reference dose.
- Cardiac biomarkers, including hs-cTnI and NT-proBNP, were measured at baseline, 3 months, 12 months, and 24 months.
- The trial was conducted at two community-based research institutions in the United States between July 2015 and March 2019.
- The effects of vitamin D3 dose on biomarkers were assessed via mixed-effects tobit models, with participants followed up to 24 months or until study termination.
TAKEAWAY:
- Higher doses of vitamin D3 supplementation did not significantly affect hs-cTnI levels compared with the low-dose group (1.6% difference; 95% CI, −5.3 to 8.9).
- No significant differences were observed in NT-proBNP levels between the high-dose and low-dose groups (−1.8% difference; 95% CI, −9.3 to 6.3).
- Both hs-cTnI and NT-proBNP levels increased in both low- and high-dose groups over time, with hs-cTnI increasing by 5.2% and 7.0%, respectively, and NT-proBNP increasing by 11.3% and 9.3%, respectively.
- The findings suggest that higher doses of vitamin D3 supplementation do not reduce markers of subclinical cardiovascular disease in older adults with low serum vitamin D levels.

Is BMI Underestimating Breast Cancer Risk in Postmenopausal Women?
TOPLINE:
Accurate body fat measures are crucial for effective cancer prevention.
METHODOLOGY:
- Researchers conducted a case-control study including 1033 breast cancer cases and 1143 postmenopausal population controls from the MCC-Spain study.
- Participants were aged 20-85 years. BMI was calculated as the ratio of weight to height squared and categorized using World Health Organization standards: < 25, 25-29.9, 30-34.9, and ≥ 35.
- CUN-BAE was calculated using a specific equation and categorized according to the estimated percentage of body fat: < 35%, 35%-39.9%, 40%-44.9%, and ≥ 45%.
- Odds ratios (ORs) were estimated with 95% CIs for both measures (BMI and CUN-BAE) for breast cancer cases using unconditional logistic regression.
TAKEAWAY:
- Excess body weight attributable to the risk for breast cancer was 23% when assessed using a BMI value > 30 and 38% when assessed using a CUN-BAE value > 40% body fat.
- Hormone receptor stratification showed that these differences in population-attributable fractions were only observed in hormone receptor–positive cases, with an estimated burden of 19.9% for BMI and 41.9% for CUN-BAE.
- The highest categories of CUN-BAE showed an increase in the risk for postmenopausal breast cancer (OR, 2.13 for body fat ≥ 45% compared with the reference category < 35%).
- No similar trend was observed for BMI, as the gradient declined after a BMI ≥ 35.
IN PRACTICE:
“The results of our study indicate that excess body fat is a significant risk factor for hormone receptor–positive breast cancer in postmenopausal women. Our findings suggest that the population impact could be underestimated when using traditional BMI estimates, and that more accurate measures of body fat, such as CUN-BAE, should be considered,” the authors of the study wrote.
SOURCE:
This study was led by Verónica Dávila-Batista, University of Las Palmas de Gran Canaria in Las Palmas de Gran Canaria, Spain. It was published online in Journal of Epidemiology and Community Health.
LIMITATIONS:
The case-control design of the study may have limited the ability to establish causal relationships. BMI was self-reported at the time of the interview for controls and 1 year before diagnosis for cancer cases, which may have introduced recall bias. The formula for CUN-BAE was calculated from a sedentary convenience sample, which may not have been representative of the general population. The small sample size of cases that did not express hormone receptors was another limitation. The study’s findings may not be generalizable to non-White populations as non-White participants were excluded.

Maternal Serum Folate Levels During Pregnancy Linked to Congenital Heart Disease Risk
TOPLINE:
Maternal serum folate levels during early to midpregnancy show a U-shaped association with congenital heart disease (CHD) risk in offspring. Both low and high folate levels are linked to an increased risk, with vitamin B12 deficiency and elevated homocysteine levels further exacerbating this risk.
METHODOLOGY:
- Researchers conducted a case-control study with 129 participants with CHD and 516 matched control participants from Guangdong Provincial People’s Hospital in China between 2015 and 2018.
- Maternal serum levels of folate, vitamin B12, and homocysteine were measured at around 16 weeks of gestation using a chemiluminescence microparticle immunoassay.
- CHD was confirmed using echocardiography, and the participants were matched by maternal age at a ratio of 1:4.
- Covariates included periconceptional folic acid supplementation, maternal education, occupation, parity, abortion history, pregnancy complications, and genetic polymorphisms related to folate metabolism.
- Conditional logistic regression was used to assess the associations, with adjustments for various covariates and sensitivity analyses excluding participants with missing genetic data.
TAKEAWAY:
- A U-shaped association was found between maternal serum folate levels and CHD risk in offspring, with both low and high levels linked to increased risk (P < .001).
- Low maternal folate levels were associated with an adjusted odds ratio (aOR) of 3.09 (95% CI, 1.88-5.08) for CHD risk, whereas high levels had an aOR of 1.81 (95% CI, 1.07-3.06).
- Using World Health Organization criteria, folate deficiency (< 5.9 ng/mL) had an aOR of 18.97 (95% CI, 3.87-93.11) and elevated levels (> 20 ng/mL) had an aOR of 5.71 (95% CI, 2.72-11.98) for CHD risk.
- Vitamin B12 deficiency and elevated homocysteine levels further increased the risk associated with both low and high maternal folate levels.
IN PRACTICE:
“Insufficient folate and vitamin B12 can lead to increased homocysteine levels, which is harmful to the cardiovascular system. Thus, homocysteine might act as a central mediator in the relationships between deficiencies in folate and vitamin B12 and the risk of CHD. Additionally, the role of folate extends beyond homocysteine mediation, contributing independently to placental implantation and vascular remodeling, irrespective of vitamin B12 and homocysteine levels,” the authors wrote.
SOURCE:
The study was led by Yanji Qu, PhD, and Jie Li, PhD, Global Health Research Center, Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences, Southern Medical University, Guangzhou, China. It was published online in JAMA Network Open.
LIMITATIONS:
The study’s limitations included the measurement of maternal serum folate levels at a single time point, which may not reflect preconception and early postconception periods. The study’s findings may not be generalizable to other populations as participants were recruited from a single cardiac referral center in Southern China. Additionally, the lack of dietary intake data limited the ability to account for related biases. The sample size, while relatively large for CHD research, may lack sufficient power for stratified analyses.
