Single and two-dose typhoid conjugate vaccine safety and immunogenicity in HIV-exposed uninfected and HIV-unexposed uninfected Malawian children.

Vaccine safety and immunogenicity data in human immunodeficiency virus (HIV)-exposed uninfected (HEU) children are important for decision-making in HIV and typhoid co-endemic countries. In an open-label study, we recruited Malawian HEU and HIV unexposed uninfected (HUU) infants aged 9 - 11 months. HEU participants were randomized to receive Vi-tetanus toxoid conjugate vaccine (Vi-TT) at 9 months, Vi-TT at 15 months, or Vi-TT at 9 and 15 months. HUU participants received Vi-TT at 9 and 15 months. Safety outcomes included solicited and unsolicited adverse events (AE) and serious AEs (SAEs) within 7 days, 28 days, and 6 months of vaccination, respectively. Serum was collected before and at day 28 after each vaccination to measure anti-Vi IgG antibodies by enzyme-linked immunosorbent assay (ELISA). Cohort 1 (66 participants) enrollment began 02 December 2019, and follow-up was terminated before completion due to the COVID-19 pandemic. Cohort 2 (100 participants) enrollment began 25 March 2020. Solicited AEs were mostly mild, with no significant differences between HEU and HUU participants or one- and two-dose groups. All six SAEs were unrelated to vaccination. Anti-Vi geometric mean titers (GMT) increased significantly from 4.1 to 4.6 ELISA units (EU)/mL at baseline to 2572.0 - 4117.6 EU/mL on day 28 post-vaccination, and similarly between HEU and HUU participants for both one- and two-dose schedules. All participants seroconverted (>4-fold increase in GMT) by the final study visit. Our findings of comparable safety and immunogenicity of Vi-TT in HUU and HEU children support country introductions with single-dose Vi-TT in HIV-endemic countries.

Study of Diagnostic Yield of Nucleic Acid Amplification Test among Tuberculous Cervical Lymphadenitis in Immunocompetent Patients.

BACKGROUND: The most common form of extrapulmonary tuberculosis (TB) is tuberculous lymphadenitis, which constitutes about 30-40% of all extrapulmonary TB cases. A new diagnostic method like the nucleic acid amplification test (NAAT) is a very sensitive and rapid test for diagnosing tuberculous cervical lymphadenopathy. It also detects rifampicin sensitivity among positive patients. OBJECTIVES: (1) To evaluate the diagnostic yield of TrueNAT for detecting Mycobacterium tuberculosis bacteria in the fine-needle aspirated samples of cervical lymph nodes compared with Ziehl-Neelsen (ZN) staining; (2) to evaluate the diagnostic yield of TrueNAT for diagnosis of tuberculosis through comparison with the cytology report of fine-needle aspiration (FNA) sample of cervical lymph node and with necrotic cervical lymph node on ultrasonography (USG) neck. MATERIALS AND METHODS: A total of 50 patients enrolled in this prospective study from January to December 2022. Demographic profile and clinical history were noted. Fine-needle aspirate samples were sent for TrueNAT assay, cytological examination, and ZN staining. USG neck was done for necrotic findings in the cervical lymph nodes. RESULTS: The TrueNAT positivity rate was 70%. TrueNAT sensitivity and specificity were assessed according to the cytology report, acid-fast bacilli (AFB) positivity on ZN stain, and the finding of necrosis in the cervical lymph node on the USG neck. The sensitivity and specificity of the TrueNAT assay were 80.49 and 77.78%, respectively, in accordance with necrosis on FNA cytology; 17.14 and 93.33%, respectively, in accordance with AFB positivity on ZN stain; and 74.29 and 33.33%, respectively, in accordance with lymph node necrosis on USG neck. CONCLUSION: The TrueNAT assay should be used as an adjunctive test in addition to the conventional cytological examination of the FNA sample of lymph nodes for the rapid diagnosis of tuberculosis. It also detects rifampicin resistance simultaneously.

Return rates and pregnancy outcomes after oocyte preservation for planned fertility delay: a systematic review and meta-analysis.

IMPORTANCE: Oocyte preservation for planned fertility delay, also referred to as social oocyte preservation or colloquially as "egg freezing," has become increasingly popular in the last few decades. Previous literature has suggested that there are gaps in counseling and expectations regarding the expected thaw rates and outcomes of preserved oocytes. OBJECTIVE: To characterize the literature on social oocyte preservation, specifically the return rates, thaw rates, clinical pregnancy rates, and live birth rates. DATA SOURCES: We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses of 7 databases (MEDLINE, EMBASE, Emcare, CINAHL, the Cochrane Library, Web of Science: Core Collection, and Scopus) until January 1, 2024. The Risk Of Bias In Non-randomized Studies of Interventions tool was used for critical appraisal. STUDY SELECTION AND SYNTHESIS: All original human research that reported data for individuals who underwent autologous oocyte preservation for planned fertility delay (i.e., not for medical indications such as chemotherapy) was included for analysis. A meta-analysis was conducted using descriptive statistics and pooled prevalence rates. Title and abstract screening and data extraction were conducted in duplicate by 2 independent reviewers for all studies until full agreement on eligibility was achieved through consensus-based discussion. MAIN OUTCOMES: Return rate among those who froze oocytes for planned fertility delay, as well as live birth rate and clinical pregnancy rate among these patients. RESULTS: After screening 1,540 references, a total of 27 studies encompassing 13,724 patients were included. Follow-up ranged from 4 to 19 years, with a median follow-up time of 7 years. A total of 17,418 oocyte retrieval cycles for planned fertility delay were reported, with most individuals undergoing a single cryopreservation cycle. Overall, 10.8% of individuals returned to thaw their eggs, with an aggregate oocyte survival rate of 81.4%. The implantation rate was 44.4% and clinical pregnancy rate was 34.2%. A live birth was reported for 28.9% of individuals across all age groups who returned to thaw eggs. CONCLUSIONS AND RELEVANCE: Individuals should be counseled regarding the low return rates after oocyte preservation for planned fertility delay.

Ethical and Policy Issues Arising in Crowdfunding for Solid Organ Transplantation: A Content Analysis of Newspaper Coverage of Recipient and Donor Fundraising Campaigns.

BACKGROUND: Solid organ transplantation improves the quality of life for patients but has significant out-of-pocket expenses for donors and recipients in the USA, leading many to utilize crowdfunding for donations to cover expenses. We sought to characterize crowdfunding for transplant patients and to identify ethical and policy issues. METHODS: We obtained newspaper articles that described crowdfunding campaigns for organ transplant patients from Nexis-Uni. Using Nvivo, we identified and analyzed article details, patient characteristics, features of campaigns, additional fundraisers, and policy and ethical issues related to crowdfunding. RESULTS: Most sources were published between 2015 and 2020. Of 231 patients identified, 43% were thoracic organ recipients and 42% were kidney recipients. GoFundMe was the most popular platform. 78% of patients reported at least one intended use of crowdfunding; medical expenses were the most cited reason. Ten percent of articles described at least one ethical or policy consideration related to crowdfunding for organ transplant. Concerns included violations of federal laws prohibiting donors from receiving "valuable consideration" for an organ, taxation of funds, loss of Medicaid or disability benefits, accountability for fund usage, and crowdfunding requirements for organ waiting list placement. In several cases, transplants were delayed due to crowdfunding concerns. CONCLUSIONS: Our findings reveal crowdfunding characteristics and financial barriers present among transplant patients. Furthermore, our study suggests that the ethical and policy implications for crowdfunding in the transplant population are not yet adequately assessed. National regulations and transplant center policies may need to be modified to address issues raised by patient crowdfunding.

Association Between Antibiotic Duration and Recurrence of Urinary Tract Infection in the Neonatal Critical Care Unit.

OBJECTIVES: Urinary tract infection (UTI) is the most common bacterial infection in infants. Current practice guidelines suggest a treatment duration of 7 to 14 days. Suboptimal therapy may increase the risk for recurrent UTIs leading to renal scarring and possibly chronic kidney disease. The primary objective is to evaluate the duration of therapy for UTIs and its association with the incidence of recurrent UTIs in a neonatal intensive care unit (NICU). The secondary objectives are to identify the risk factors and the most common organisms for recurrent UTIs. METHODS: Patients were identified via the diagnosis codes for UTIs and were included if admitted to the NICU and if they received antibiotics prior to hospital discharge. Patients were divided into 2 groups: antibiotic treatment for 7 days or fewer and antibiotic treatment for greater than 7 days. RESULTS: Eighty-six infants were included in the study. Twenty-six patients received antibiotics for 7 days or fewer, and 60 for more than 7 days. In the study, the median birth weight was 977 g and the median gestational age was 27.6 weeks. There was no significant difference in the rate of recurrent UTIs between the 2 groups (p = 0.66). However, in the subgroup analysis, the incidence was higher for patients receiving antibiotic therapy for fewer than 7 days versus 7 days (p = 0.03). CONCLUSION: There was no difference in recurrence of UTI between treatment groups (≤7 days versus >7 days), and recurrence was seen in a higher percentage of patients with a urinary tract anomaly.

Breastfeeding Perceptions and Decisions among Hispanic Participants in the Special Supplemental Nutrition Program for Women, Infants, and Children: A Qualitative Study.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a nutrition assistance program in the U.S. WIC served 2.5 million eligible Hispanic women, infants, and children under the age of five in 2021, which is WIC's largest racial/ethnic group. However, limited research has been conducted to understand Hispanic WIC participants' perceptions of WIC breastfeeding recommendations and their breastfeeding decisions. For this qualitative study, we interviewed 18 of these pregnant and postpartum WIC participants on their experiences and decision-making processes related to breastfeeding. Hispanic cultures and home country norms were identified as prominent influences on breastfeeding decisions, along with perceptions of WIC's breastfeeding support. These results can help the WIC program to refine its breastfeeding education to better meet the needs of Hispanic participants.

Depression among currently married ever pregnant adolescents in Uttar Pradesh and Bihar: Evidence from understanding the lives of adolescents and young adults (UDAYA) survey, India.

Background: Depression is a major public health concern among Indian adolescents. Pre- and post-natal depression can often alter fetal development and have negative consequences on the physical and mental health of the mother. This paper aims to draw attention to the prevalence of depression and its correlates among currently married, ever-pregnant adolescents from two Indian States, i.e. Uttar Pradesh and Bihar. Methods: This study utilizes data from a subsample (n = 3116) of the prospective cohort study Understanding the Lives of Adolescents and Young Adults (UDAYA) among 10 to 19 year-old adolescents. Bivariate analysis was performed to assess the prevalence of depression by sociodemographic and behavioral characteristics. To further access the predictors associated with depression a logistic regression model was applied. Results: Around one-tenth (9%) of pregnant adolescents had depression. Regression analysis indicated that substance use, religion, autonomy, considering attempting suicide, premarital relationship, violence, dowry, adverse pregnancy outcome, menstrual problem, and parental pressure for the child immediately after marriage were significantly associated with depression. Conclusions: This study confirms the pre-existing annotation that teen pregnancy is linked with depression. Findings indicate that Adolescent mothers experiencing violence, and a history of adverse pregnancy outcomes are at increased risk of developing depression. These study findings call for an urgent need to address depression among adolescent mothers.

Evaluating the relationship between ciprofloxacin prescription and non-susceptibility in Salmonella Typhi in Blantyre, Malawi: an observational study.

BACKGROUND: Ciprofloxacin is the first-line drug for treating typhoid fever in many countries in Africa with a high disease burden, but the emergence of non-susceptibility poses a challenge to public health programmes. Through enhanced surveillance as part of vaccine evaluation, we investigated the occurrence and potential determinants of ciprofloxacin non-susceptibility in Blantyre, Malawi. METHODS: We conducted systematic surveillance of typhoid fever cases and antibiotic prescription in two health centres in Blantyre, Malawi, between Oct 1, 2016, and Oct 31, 2019, as part of the STRATAA and TyVAC studies. In addition, blood cultures were taken from eligible patients presenting at Queen Elizabeth Central Hospital, Blantyre, as part of routine diagnosis. Inclusion criteria were measured or reported fever, or clinical suspicion of sepsis. Microbiologically, we identified Salmonella enterica serotype Typhi (S Typhi) isolates with a ciprofloxacin non-susceptible phenotype from blood cultures, and used whole-genome sequencing to identify drug-resistance mutations and phylogenetic relationships. We constructed generalised linear regression models to investigate associations between the number of ciprofloxacin prescriptions given per month to study participants and the proportion of S Typhi isolates with quinolone resistance-determining region (QRDR) mutations in the following month. FINDINGS: From 46 989 blood cultures from Queen Elizabeth Central Hospital, 502 S Typhi isolates were obtained, 30 (6%) of which had either decreased ciprofloxacin susceptibility, or ciprofloxacin resistance. From 11 295 blood cultures from STRATAA and TyVAC studies, 241 microbiologically confirmed cases of typhoid fever were identified, and 198 isolates from 195 participants sequenced (mean age 12·8 years [SD 10·2], 53% female, 47% male). Between Oct 1, 2016, and Aug 31, 2019, of 177 typhoid fever cases confirmed by whole-genome sequencing, four (2%) were caused by S Typhi with QRDR mutations, compared with six (33%) of 18 cases between Sept 1 and Oct 31, 2019. This increase was associated with a preceding spike in ciprofloxacin prescriptions. Every additional prescription of ciprofloxacin given to study participants in the preceding month was associated with a 4·2% increase (95% CI 1·8-7·0) in the relative risk of isolating S Typhi with a QRDR mutation (p=0·0008). Phylogenetic analysis showed that S Typhi isolates with QRDR mutations from September and October, 2019, belonged to two distinct subclades encoding two different QRDR mutations, and were closely related (4-10 single-nucleotide polymorphisms) to susceptible S Typhi endemic to Blantyre. INTERPRETATION: We postulate a causal relationship between increased ciprofloxacin prescriptions and an increase in fluoroquinolone non-susceptibility in S Typhi. Decreasing ciprofloxacin use by improving typhoid diagnostics, and reducing typhoid fever cases through the use of an efficacious vaccine, could help to limit the emergence of resistance.

Therapeutic targeting of cellular senescence in diabetic macular edema: preclinical and phase 1 trial results.

Compromised vascular endothelial barrier function is a salient feature of diabetic complications such as sight-threatening diabetic macular edema (DME). Current standards of care for DME manage aspects of the disease, but require frequent intravitreal administration and are poorly effective in large subsets of patients. Here we provide evidence that an elevated burden of senescent cells in the retina triggers cardinal features of DME pathology and conduct an initial test of senolytic therapy in patients with DME. In cell culture models, sustained hyperglycemia provoked cellular senescence in subsets of vascular endothelial cells displaying perturbed transendothelial junctions associated with poor barrier function and leading to micro-inflammation. Pharmacological elimination of senescent cells in a mouse model of DME reduces diabetes-induced retinal vascular leakage and preserves retinal function. We then conducted a phase 1 single ascending dose safety study of UBX1325 (foselutoclax), a senolytic small-molecule inhibitor of BCL-xL, in patients with advanced DME for whom anti-vascular endothelial growth factor therapy was no longer considered beneficial. The primary objective of assessment of safety and tolerability of UBX1325 was achieved. Collectively, our data suggest that therapeutic targeting of senescent cells in the diabetic retina with a BCL-xL inhibitor may provide a long-lasting, disease-modifying intervention for DME. This hypothesis will need to be verified in larger clinical trials. ClinicalTrials.gov identifier: NCT04537884 .

Efficacy of typhoid conjugate vaccine: final analysis of a 4-year, phase 3, randomised controlled trial in Malawian children.

BACKGROUND: Randomised controlled trials of typhoid conjugate vaccines among children in Africa and Asia have shown high short-term efficacy. Data on the durability of protection beyond 2 years are sparse. We present the final analysis of a randomised controlled trial in Malawi, encompassing more than 4 years of follow-up, with the aim of investigating vaccine efficacy over time and by age group. METHODS: In this phase 3, double-blind, randomised controlled efficacy trial in Blantyre, Malawi, healthy children aged 9 months to 12 years were randomly assigned (1:1) by an unmasked statistician to receive a single dose of Vi polysaccharide conjugated to tetanus toxoid vaccine (Vi-TT) or meningococcal capsular group A conjugate (MenA) vaccine. Children had to have no previous history of typhoid vaccination and reside in the study areas for inclusion and were recruited from government schools and health centres. Participants, their parents or guardians, and the study team were masked to vaccine allocation. Nurses administering vaccines were unmasked. We did surveillance for febrile illness from vaccination until follow-up completion. The primary outcome was first occurrence of blood culture-confirmed typhoid fever. Eligible children who were randomly assigned and vaccinated were included in the intention-to-treat analyses. This trial is registered at ClinicalTrials.gov, NCT03299426. FINDINGS: Between Feb 21, 2018, and Sept 27, 2018, 28 130 children were vaccinated; 14 069 were assigned to receive Vi-TT and 14 061 to receive MenA. After a median follow-up of 4·3 years (IQR 4·2-4·5), 24 (39·7 cases per 100 000 person-years) children in the Vi-TT group and 110 (182·7 cases per 100 000 person-years) children in the MenA group were diagnosed with a first episode of blood culture-confirmed typhoid fever. In the intention-to-treat population, efficacy of Vi-TT was 78·3% (95% CI 66·3-86·1), and 163 (129-222) children needed to be vaccinated to prevent one case. Efficacies by age group were 70·6% (6·4-93·0) for children aged 9 months to 2 years; 79·6% (45·8-93·9) for children aged 2-4 years; and 79·3% (63·5-89·0) for children aged 5-12 years. INTERPRETATION: A single dose of Vi-TT is durably efficacious for at least 4 years among children aged 9 months to 12 years and shows efficacy in all age groups, including children younger than 2 years. These results support current WHO recommendations in typhoid-endemic areas for mass campaigns among children aged 9 months to 15 years, followed by routine introduction in the first 2 years of life.

Racial Disparities Among Predicted Bronchopulmonary Dysplasia Risk Outcomes in Premature Infants Born <30 Weeks Gestation.

Background and Objective: There is extensive literature to support eliminating race-based risk stratification. The National Institute of Child Health and Human Development (NICHD) calculator, used to predict risk of bronchopulmonary dysplasia (BPD), includes race as a variable. We sought to investigate how utilizing race in determination of risk for BPD may lead to inequitable care. Methods: The study included a retrospective cohort of infants born <30 weeks gestation between January 2016 and February 2022. The primary outcome was the difference in predictive risk of BPD for non-Hispanic Black compared to non-Hispanic White infants. The secondary outcome was the disparity in theoretical administration of post-natal corticosteroids when the calculator was applied to the cohort. Analysis included paired T-tests and Chi-Square. Results: Of the 273 infants studied, 154 were non-Hispanic Black (56%). There was no difference between the groups in gestation or respiratory support on day of life (DOL) 14 or 28. The predicted risk of moderate or severe BPD in non-Hispanic White babies was greater than non-Hispanic Black babies on both DOL 14 and 28 (p<0.01). When applied retrospectively to the cohort, the calculator resulted in differences in corticosteroid administration (risk >40%-non-Hispanic White 51.3% vs. non-Hispanic Black 35.7%, p=0.010; risk >50%-non-Hispanic White 42.9% vs. non-Hispanic Black 29.9%, p=0.026). Conclusion: When applied to our study cohort, the calculator resulted in a reduction in the predicted risk of BPD in non-Hispanic Black infants. If utilized to guide treatment, the calculator can potentially lead to disparities in care for non-Hispanic Black infants.

Neurally Adjusted Ventilatory Assist Versus Pressure Support Ventilation: A Comprehensive Review.

Mechanical ventilation serves as crucial life support for critically ill patients. Although it is life-saving prolonged ventilation carries risks and complications like barotrauma, Ventilator-associated pneumonia, sepsis, and many others. Optimizing patient-ventilator interactions and facilitating early weaning is necessary for improved intensive care unit (ICU) outcomes. Traditionally Pressure support ventilation (PSV) mode is widely used for weaning patients who are intubated and mechanically ventilated. Neurally adjusted ventilatory assist (NAVA) mode of the ventilator is an emerging ventilator mode that delivers pressure depending on the patient's respiratory drive, which in turn prevents over-inflation and improves the patient's ventilator interactions. Our article revises and compares the effectiveness of NAVA compared to PSV ventilation under different contexts. Overall we conclude that NAVA level of ventilation can be safely administered in a patient with acute respiratory failure, provided diaphragmatic paralysis is not considered. NAVA improves asynchrony index, wean-off time, and sleep quality and is associated with increased ventilator-free days. These results are based on small-scale studies with low power, and further studies are warranted in large-scale cohorts with more diverse populations to confirm these results.

Integration of transcriptomes of senescent cell models with multi-tissue patient samples reveals reduced COL6A3 as an inducer of senescence.

Senescent cells are a major contributor to age-dependent cardiovascular tissue dysfunction, but knowledge of their in vivo cell markers and tissue context is lacking. To reveal tissue-relevant senescence biology, we integrate the transcriptomes of 10 experimental senescence cell models with a 224 multi-tissue gene co-expression network based on RNA-seq data of seven tissues biopsies from ∼600 coronary artery disease (CAD) patients. We identify 56 senescence-associated modules, many enriched in CAD GWAS genes and correlated with cardiometabolic traits-which supports universality of senescence gene programs across tissues and in CAD. Cross-tissue network analyses reveal 86 candidate senescence-associated secretory phenotype (SASP) factors, including COL6A3. Experimental knockdown of COL6A3 induces transcriptional changes that overlap the majority of the experimental senescence models, with cell-cycle arrest linked to modulation of DREAM complex-targeted genes. We provide a transcriptomic resource for cellular senescence and identify candidate biomarkers, SASP factors, and potential drivers of senescence in human tissues.

Pediatric Dentists' and Guardians' Perceptions of Follow-Up Appointments After Dental Rehabilitation Under General Anesthesia.

Purpose: It has been suggested that follow-up visits for pediatric patients after full-mouth dental rehabilitation (FMDR) under general anesthesia (GA) are important to evaluate healing and restorative treatment, review oral hygiene instruction, provide nutritional counseling and address guardians' concerns. The purpose of this study was to evaluate pediatric dentists' current utilization of follow-up visits after GA and to evaluate pediatric dentists' and guardians' perceptions of their purpose and value. Methods: Three separate surveys were administered: (1) pediatric dentist survey, (2) guardian pre-appointment survey and (3) guardian post-appointment survey. The guardian surveys examined their perceptions of a follow-up visit before and after FMDR under GA. The pediatric dentist survey examined current utilization and perception of follow-up appointments. Results: Most clinicians (72 percent) reported scheduling a follow-up visit. Providers generally agreed that the post-operative appointments were important (69 percent). Of the guardians who attended the follow-up visit, 96.3 percent agreed that the post- operative visit was useful. Conclusion: Both pediatric dentists and guardians of patients undergoing FMDR under GA agreed that a follow-up visit after GA was valuable despite low complication rates.

Long-term trends of HIV/AIDS incidence in India: an application of joinpoint and age-period-cohort analyses: a gendered perspective.

Background: Monitoring the transmission patterns of human immunodeficiency virus (HIV) in a population is fundamental for identifying the key population and designing prevention interventions. In the present study, we aimed to estimate the gender disparities in HIV incidence and the age, period, and cohort effects on the incidence of HIV in India for identifying the predictors that might have led to changes in the last three decades. Data and methods: This study utilizes data from the Global Burden of Disease Study for the period 1990-2019. The joinpoint regression analysis was employed to identify the magnitude of the changes in age-standardized incidence rates (ASIRs) of HIV. The average annual percentage changes in the incidence were computed, and the age-period-cohort analysis was performed. Results: A decreasing trend in the overall estimates of age-standardized HIV incidence rates were observed in the period 1990-2019. The joinpoint regression analysis showed that the age-standardized incidence significantly declined from its peak in 1997 to 2019 (38.0 and 27.6 among males and females per 100,000 in 1997 to 5.4 and 4.6, respectively, in 2019). The APC was estimated to be 2.12 among males and 1.24 among females for the period 1990-2019. In recent years, although the gender gap in HIV incidence has reduced, females were observed to bear a proportionately higher burden of HIV incidence. Age effect showed a decline in HIV incidence by 91.1 and 70.1% among males and females aged between 15-19 years and 75-79 years. During the entire period from 1990-1994 to 2015-2019, the RR of HIV incidence decreased by 36.2 and 33.7% among males and females, respectively. Conclusion: India is experiencing a decline in new HIV infections in recent years. However, the decline is steeper for males than for females. Findings highlight the necessity of providing older women and young women at risk with effective HIV prevention. This study emphasizes the need for large-scale HIV primary prevention efforts for teenage girls and young women.

Forming the Perception of WIC Infant Feeding Recommendations: A Qualitative Study.

Nearly half of newborns in the United States are enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Promoting breastfeeding is a programmatic priority, although formula vouchers are provided for those who do not exclusively breastfeed. Previous literature suggests that participant perception of WIC's breastfeeding recommendations is a significant factor predicting breastfeeding initiation, duration, and exclusivity outcomes. However, little is known about how participants' perceptions of WIC's breastfeeding recommendations are formed. To address this knowledge gap, we conducted a qualitative pilot study in Nevada, interviewing 10 postpartum WIC mothers and 12 WIC staff who had interacted with participants regarding infant feeding. Results showed participants and staff reported various perceptions of what WIC recommends, the factors that contribute to these perceptions, and how these perceptions affect breastfeeding practices. Respondents also described that WIC has a negative legacy as the "free formula program," and that environmental factors, such as the recent formula recall, have had an impact on participants' infant feeding practices. More effective public campaigns and programmatic strategies are needed to target participants' prenatal self-efficacy and to communicate the availability of skilled lactation support in the early postpartum period to improve participants' perceptions of WIC's position on breastfeeding.

Insights into the perinatal phenotype of Kabuki syndrome in infants identified by genome-wide sequencing.

Increasing use of unbiased genomic sequencing in critically ill infants can expand understanding of rare diseases such as Kabuki syndrome (KS). Infants diagnosed with KS through genome-wide sequencing performed during the initial hospitalization underwent retrospective review of medical records. Human phenotype ontology terms used in genomic analysis were aggregated and analyzed. Clinicians were surveyed regarding changes in management and other care changes. Fifteen infants met inclusion criteria. KS was not suspected prior to genomic sequencing. Variants were classified as Pathogenic (n = 10) or Likely Pathogenic (n = 5) by American College of Medical Genetics and Genomics Guidelines. Fourteen variants were de novo (KMT2D, n = 12, KDM6A, n = 2). One infant inherited a likely pathogenic variant in KMT2D from an affected father. Frequent findings involved cardiovascular (14/15) and renal (7/15) systems, with palatal defects also identified (6/15). Three infants had non-immune hydrops. No minor anomalies were universally documented; ear anomalies, micrognathia, redundant nuchal skin, and hypoplastic nails were common. Changes in management were reported in 14 infants. Early use of unbiased genome-wide sequencing enabled a molecular diagnosis prior to clinical recognition including infants with atypical or rarely reported features of KS while also expanding the phenotypic spectrum of this rare disorder.

Protecting Low-Income Consumers in the Era of Digital Grocery Shopping: Implications for WIC Online Ordering.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is now expected to allow participants to redeem their food benefits online, i.e., via online ordering, rather than only in-store. However, it is unclear how this new benefit redemption model may impact participants' welfare since vendors may have an asymmetric information advantage compared with WIC customers. The WIC online ordering environment may also change the landscape for WIC vendors, which will eventually affect WIC participants. To protect WIC consumers' rights in the new online ordering model, policymakers need an appropriate legal and regulatory framework. This narrative review provides that framework by reviewing the literature, legal treatises, and reports on enforceable laws and regulations in the U.S. relevant to digital marketing. The results identify key issues that may arise with adopting WIC online ordering. This paper suggests "privacy, transparency, and fairness" as guiding principles to protect the welfare of WIC participants in WIC online ordering.

A Systematic Review of Marketing Practices Used in Online Grocery Shopping: Implications for WIC Online Ordering.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) plans to allow participants to redeem their food package benefits online, i.e., online ordering. As grocery shopping online has become more common, companies have developed strategies to market food products to customers using online (or mobile) grocery shopping platforms. There is a significant knowledge gap in how these strategies may influence WIC participants who choose to shop for WIC foods online. This review examines the relevant literature to (1) identify food marketing strategies used in online grocery shopping platforms, (2) understand how these strategies influence consumer behavior and consumer diet, and (3) consider the implications for WIC participants. A total of 1862 references were identified from a systematic database search, of which 83 were included for full-text screening and 18 were included for data extraction and evidence synthesis. The included studies provide policymakers and other stakeholders involved in developing WIC online order processes with valuable information about the factors that shape healthy food choices in the online food retail environment. Findings indicate that some marketing interventions, such as nutrition labeling and food swaps, may encourage healthier food choices in the online environment and could potentially be tailored to reinforce WIC messaging about a healthy diet.
