RESUMEN
Two models employed to integrate community health workers (CHWs) in health care settings are community-clinical linkages and employment within health care. Our objective was to understand the variability in how these models are implemented. We conducted a mixed-methods study across a large health system that included CHW focus groups and electronic health record data on patients referred to the teams. We identified three primary themes in the four focus groups (N = 29) and found differences in the demographics and health care use of the 1,097 patients. Both community- and clinically embedded CHWs reported addressing diverse patient needs; yet, challenges persist in integrating both models.
RESUMEN
OBJECTIVES: In 2014, New York City initiated a childcare influenza vaccine requirement to increase influenza vaccination rates among children aged 6-59 months attending city-regulated childcare, including prekindergarten. We evaluated the requirement's effect on vaccination rates in childcare-aged children in New York City. METHODS: We examined influenza vaccination rates in children aged 6-59 months and by age groups of 1, 2, 3, and 4 years for 8 influenza seasons (2012-2013 through 2019-2020), representing 2 seasons before the requirement, 2 seasons during the requirement, 2 seasons after its suspension, and 2 seasons after its reinstatement. We also assessed rates in a comparison group of children aged 5-8 years. We performed a difference-in-differences analysis to compare rate differences in age groups when the requirement was and was not in effect. We considered P < .05 as significant based on the Wald χ2 test. RESULTS: Influenza vaccination rates among children aged 6-59 months increased 3.7 percentage points (from 47.7% to 51.4%) by the requirement's second year and declined 6.7 percentage points to 44.7% after suspension. After reinstatement, rates increased 10.7 percentage points to 55.4%. Rate changes were most pronounced among 4-year-olds, increasing 12.7 percentage points (from 45.3% to 58.0%) by the requirement's second year, declining 14.1 percentage points to 43.9% after suspension, and increasing 22.2 percentage points to 66.1% after reinstatement. In the comparison group, rates increased 4.9 percentage points (from 36.5% to 41.4%) after reinstatement. Rates increased significantly among 4-year-olds before versus at the initial requirement and decreased significantly after suspension. After reinstatement, rates increased significantly among all groups except 1-year-olds. CONCLUSION: The New York City influenza vaccine requirement improved influenza vaccination rates among preschool-aged children, adding to the evidence base showing that vaccine requirements raise vaccination rates.
RESUMEN
IMPORTANCE: Routine vaccinations are key to prevent outbreaks of vaccine-preventable diseases. However, there have been documented declines in routine childhood vaccinations in the U.S. and worldwide during the COVID-19 pandemic. OBJECTIVE: Assess how the COVID-19 pandemic impacted routine childhood vaccinations by evaluating vaccination coverage for routine childhood vaccinations for children born in 2016-2021. METHODS: Data on routine childhood vaccinations reported to CDC by nine U.S. jurisdictions via the immunization information systems (IISs) by December 31, 2022, were available for analyses. Population size for each age group was obtained from the National Center for Health Statistics' Bridging Population Estimates. MAIN OUTCOMES AND MEASURES: Vaccination coverage for routine childhood vaccinations at age three months, five months, seven months, one year, and two years was calculated by vaccine type and overall, for 4:3:1:3:3:1:4 series (≥4 doses DTaP, ≥3 doses Polio, ≥1 dose MMR, ≥3 doses Hib, ≥3 doses Hepatitis B, ≥1 dose Varicella, and ≥ 4 doses pneumococcal conjugate), for each birth cohort year and by jurisdiction. RESULTS: Overall, there was a 10.4 percentage point decrease in the 4:3:1:3:3:1:4 series in those children born in 2020 compared to those children born in 2016. As of December 31, 2022, 71.0% and 71.3% of children born in 2016 and 2017, respectively, were up to date on their routine childhood vaccinations by two years of age compared to 69.1%, 64.7% and 60.6% for children born in 2018, 2019, and 2020, respectively. CONCLUSIONS AND RELEVANCE: The decline in vaccination coverage for routine childhood vaccines is concerning. In order to protect population health, strategic efforts are needed by health care providers, schools, parents, as well as state, local, and federal governments to work together to address these declines in vaccination coverage during the COVID-19 pandemic to prevent outbreaks of vaccine preventable diseases by maintaining high levels of population immunity.
RESUMEN
Background: Experiencing Failure to Thrive or malnutrition in early years has been associated with children later displaying low Intelligence Quotient (IQ). The current study's aim was to examine whether Failure to Thrive in Toddlers with Lack of Interest in Eating and Food, a subtype of Avoidant/Restrictive Food Intake Disorder as defined by DSM-5, which has also previously been identified as Infantile Anorexia (IA), was associated with poor cognitive development outcomes during later childhood. Methods: The IQs and growth parameter of 30 children (53% female) previously diagnosed and treated for IA at 12 to 42 months of age, were reevaluated at a mean age of 10.0 years (SD = 2.1 years) and compared to 30 matched control children. Children's growth was assessed using Z-scores and their cognitive development was measured using the Wechsler Intelligence Scale for Children-4th Edition. Results: None of the growth parameters were significantly related to IQ. Further, IQ scores of children previously diagnosed with IA and control children were not significantly different. However, the education level of children's fathers had a significantly positive effect on IQ. Conclusions: Our study highlights the disjunction between growth parameters and IQ within our sample. Overall, our findings suggest that the primary target of intervention for these children should be the parent-child conflict around the feeding relationship, rather than a focus on the child's weight itself. Finally, our results confirm the relevance to include fathers in the intervention of these children.
RESUMEN
BACKGROUND: SARS-CoV-2 Omicron variants have the potential to impact vaccine effectiveness and duration of vaccine-derived immunity. We analyzed U.S. multi-jurisdictional COVID-19 vaccine breakthrough surveillance data to examine potential waning of protection against SARS-CoV-2 infection for the Pfizer-BioNTech (BNT162b) primary vaccination series by age. METHODS: Weekly numbers of SARS-CoV-2 infections during January 16, 2022-May 28, 2022 were analyzed by age group from 22 U.S. jurisdictions that routinely linked COVID-19 case surveillance and immunization data. A life table approach incorporating line-listed and aggregated COVID-19 case datasets with vaccine administration and U.S. Census data was used to estimate hazard rates of SARS-CoV-2 infections, hazard rate ratios (HRR) and percent reductions in hazard rate comparing unvaccinated people to people vaccinated with a Pfizer-BioNTech primary series only, by age group and time since vaccination. RESULTS: The percent reduction in hazard rates for persons 2 weeks after vaccination with a Pfizer-BioNTech primary series compared with unvaccinated persons was lowest among children aged 5-11 years at 35.5% (95% CI: 33.3%, 37.6%) compared to the older age groups, which ranged from 68.7%-89.6%. By 19 weeks after vaccination, all age groups showed decreases in the percent reduction in the hazard rates compared with unvaccinated people; with the largest declines observed among those aged 5-11 and 12-17 years and more modest declines observed among those 18 years and older. CONCLUSIONS: The decline in vaccine protection against SARS-CoV-2 infection observed in this study is consistent with other studies and demonstrates that national case surveillance data were useful for assessing early signals in age-specific waning of vaccine protection during the initial period of SARS-CoV-2 Omicron variant predominance. The potential for waning immunity during the Omicron period emphasizes the importance of continued monitoring and consideration of optimal timing and provision of booster doses in the future.

Healthcare workers in the hospital environment are at risk of infection and body fluids such as saliva, bacterial contamination, oral bacteria, etc. directly or indirectly exacerbate this issue. These bio-contaminants, when adhered to hospital linens and clothing, grow substantially, as conventional textile products provide a favorable medium for bacterial and viral growth, adding to the risk of transmitting infectious diseases in the hospital environment. Textiles with durable antimicrobial properties prevent microbial colonization on their surfaces and help contain the spread of pathogens. This longitudinal study aimed to investigate the antimicrobial performance of PHMB-treated healthcare uniforms during prolonged usage and repetitive laundry cycles in a hospital environment. The PHMB-treated healthcare uniforms displayed non-specific antimicrobial properties and remained efficient (>99% against S. aureus and K. pneumoniae) after use for 5 months. With the fact that no antimicrobial resistance was reported towards PHMB, the presented PHMB-treated uniform may reduce infection in hospital settings by minimizing the acquisition, retention, and transmission of infectious diseases on textile products.
RESUMEN
ABSTRACT: Observational studies demonstrated 30% to 40% effectiveness of outer-membrane vesicle (OMV) meningococcal serogroup B vaccines against gonorrhea. To explore whether healthy vaccinee bias influenced such findings, we examined the effectiveness of MenB-FHbp, a non-OMV vaccine that is not protective against gonorrhea. MenB-FHbp was ineffective against gonorrhea. Healthy vaccinee bias likely did not confound earlier studies of OMV vaccines.

BACKGROUND: Declining antimicrobial susceptibility to current gonorrhoea antibiotic treatment and inadequate treatment options have raised the possibility of untreatable gonorrhoea. New prevention approaches, such as vaccination, are needed. Outer membrane vesicle meningococcal serogroup B vaccines might be protective against gonorrhoea. We evaluated the effectiveness of a serogroup B meningococcal outer membrane vesicle vaccine (MenB-4C) against gonorrhoea in individuals aged 16-23 years in two US cities. METHODS: We identified laboratory-confirmed gonorrhoea and chlamydia infections among individuals aged 16-23 years from sexually transmitted infection surveillance records in New York City and Philadelphia from 2016 to 2018. We linked gonorrhoea and chlamydia case records to immunisation registry records to determine MenB-4C vaccination status at infection, defined as complete vaccination (two MenB-4C doses administered 30-180 days apart), partial vaccination (single MenB-4C vaccine dose), or no vaccination (serogroup B meningococcal vaccine naive). Using log-binomial regression with generalised estimating equations to account for correlations between multiple infections per patient, we calculated adjusted prevalence ratios (APR) and 95% CIs to determine if vaccination was protective against gonorrhoea. We used individual-level data for descriptive analyses and infection-level data for regression analyses. FINDINGS: Between Jan 1, 2016, and Dec 31, 2018, we identified 167 706 infections (18 099 gonococcal infections, 124 876 chlamydial infections, and 24 731 gonococcal and chlamydial co-infections) among 109 737 individuals linked to the immunisation registries. 7692 individuals were vaccinated, of whom 4032 (52·4%) had received one dose, 3596 (46·7%) two doses, and 64 (<1·0%) at least three doses. Compared with no vaccination, complete vaccination series (APR 0·60, 95% CI 0·47-0·77; p<0·0001) and partial vaccination series (0·74, 0·63-0·88; p=0·0012) were protective against gonorrhoea. Complete MenB-4C vaccination series was 40% (95% CI 23-53) effective against gonorrhoea and partial MenB-4C vaccination series was 26% (12-37) effective. INTERPRETATION: MenB-4C vaccination was associated with a reduced gonorrhoea prevalence. MenB-4C could offer cross-protection against Neisseria gonorrhoeae. Development of an effective gonococcal vaccine might be feasible with implications for gonorrhoea prevention and control. FUNDING: None.

BACKGROUND: Interprofessional student hotspotting involves experiential and longitudinal learning about team-based care for patients with complex medical and social needs. As an emerging strategy for interprofessional education, there have been few research studies to examine student perspectives. PURPOSE: This study used a descriptive qualitative approach to examine the experiences and perspectives of health professions students who participated in a six-month interprofessional student hotspotting program. METHODS: At the end of the program, focus group interviews were conducted with 24 health professions students from medicine, social work, pharmacy, nursing, and health psychology. RESULTS: Thematic analysis revealed four themes: Observed benefits of interprofessional collaboration; Gained skills for collaborative care; Experienced difficulty managing group dynamics; and Learned approaches to caring for complex patients. CONCLUSION: The hotspotting program helped deepen students' appreciation for interprofessional team-based care. Repeated practice of teamwork skills during the six-month clinical learning experience resulted in students feeling more prepared to provide collaborative care for complex patients.

Influenza causes considerable morbidity and mortality in the United States. Between 2010 and 2020, an estimated 9-41 million cases resulted in 140,000-710,000 hospitalizations and 12,000-52,000 deaths annually (1). As the United States enters the 2021-22 influenza season, the potential impact of influenza illnesses is of concern given that influenza season will again coincide with the ongoing COVID-19 pandemic, which could further strain overburdened health care systems. The Advisory Committee on Immunization Practices (ACIP) recommends routine annual influenza vaccination for the 2021-22 influenza season for all persons aged ≥6 months who have no contraindications (2). To assess the potential impact of the COVID-19 pandemic on influenza vaccination coverage, the percentage change between administration of at least 1 dose of influenza vaccine during September-December 2020 was compared with the average administered in the corresponding periods in 2018 and 2019. The data analyzed were reported from 11 U.S. jurisdictions with high-performing state immunization information systems.* Overall, influenza vaccine administration was 9.0% higher in 2020 compared with the average in 2018 and 2019, combined. However, in 2020, the number of influenza vaccine doses administered to children aged 6-23 months and children aged 2-4 years, was 13.9% and 11.9% lower, respectively than the average for each age group in 2018 and 2019. Strategic efforts are needed to ensure high influenza vaccination coverage among all age groups, especially children aged 6 months-4 years who are not yet eligible to receive a COVID-19 vaccine. Administration of influenza vaccine and a COVID-19 vaccine among eligible populations is especially important to reduce the potential strain that influenza and COVID-19 cases could place on health care systems already overburdened by COVID-19.

COVID-19 vaccine breakthrough infection surveillance helps monitor trends in disease incidence and severe outcomes in fully vaccinated persons, including the impact of the highly transmissible B.1.617.2 (Delta) variant of SARS-CoV-2, the virus that causes COVID-19. Reported COVID-19 cases, hospitalizations, and deaths occurring among persons aged ≥18 years during April 4-July 17, 2021, were analyzed by vaccination status across 13 U.S. jurisdictions that routinely linked case surveillance and immunization registry data. Averaged weekly, age-standardized incidence rate ratios (IRRs) for cases among persons who were not fully vaccinated compared with those among fully vaccinated persons decreased from 11.1 (95% confidence interval [CI] = 7.8-15.8) to 4.6 (95% CI = 2.5-8.5) between two periods when prevalence of the Delta variant was lower (<50% of sequenced isolates; April 4-June 19) and higher (≥50%; June 20-July 17), and IRRs for hospitalizations and deaths decreased between the same two periods, from 13.3 (95% CI = 11.3-15.6) to 10.4 (95% CI = 8.1-13.3) and from 16.6 (95% CI = 13.5-20.4) to 11.3 (95% CI = 9.1-13.9). Findings were consistent with a potential decline in vaccine protection against confirmed SARS-CoV-2 infection and continued strong protection against COVID-19-associated hospitalization and death. Getting vaccinated protects against severe illness from COVID-19, including the Delta variant, and monitoring COVID-19 incidence by vaccination status might provide early signals of changes in vaccine-related protection that can be confirmed through well-controlled vaccine effectiveness (VE) studies.

After the March 2020 declaration of the COVID-19 pandemic in the United States, an analysis of provider ordering data from the federally funded Vaccines for Children program found a substantial decrease in routine pediatric vaccine ordering (1), and data from New York City and Michigan indicated sharp declines in routine childhood vaccine administration in these areas (2,3). In November 2020, CDC interim guidance stated that routine vaccination of children and adolescents should remain an essential preventive service during the COVID-19 pandemic (4,5). To further understand the impact of the pandemic on routine childhood and adolescent vaccination, vaccine administration data during March-September 2020 from 10 U.S. jurisdictions with high-performing* immunization information systems were assessed. Fewer administered doses of routine childhood and adolescent vaccines were recorded in all 10 jurisdictions during March-September 2020 compared with those recorded during the same period in 2018 and 2019. The number of vaccine doses administered substantially declined during March-May 2020, when many jurisdictions enacted stay-at-home orders. After many jurisdictions lifted these orders, the number of vaccine doses administered during June-September 2020 approached prepandemic baseline levels, but did not increase to the level that would have been necessary to catch up children who did not receive routine vaccinations on time. This lag in catch-up vaccination might pose a serious public health threat that would result in vaccine-preventable disease outbreaks, especially in schools that have reopened for in-person learning. During the past few decades, the United States has achieved a substantial reduction in the prevalence of vaccine-preventable diseases driven in large part to the ongoing administration of routinely recommended pediatric vaccines. These efforts need to continue even during the COVID-19 pandemic to reduce the morbidity and mortality from vaccine-preventable diseases. Health care providers should assess the vaccination status of all pediatric patients, including adolescents, and contact those who are behind schedule to ensure that all children are fully vaccinated.

BACKGROUND: Extracellular vesicles (EVs) have been broadly studied in malaria for nearly a decade. These vesicles carry various functional biomolecules including RNA families such as microRNAs (miRNA). These EVs-derived microRNAs have numerous roles in host-parasite interactions and are considered promising biomarkers for disease severity. However, this field lacks clinical studies of malaria-infected samples. In this study, EV specific miRNAs were isolated from the plasma of patients from Thailand infected with Plasmodium vivax and Plasmodium falciparum. In addition, it is postulated that these miRNAs were differentially expressed in these groups of patients and had a role in disease onset through the regulation of specific target genes. METHODS: EVs were purified from the plasma of Thai P. vivax-infected patients (n = 19), P. falciparum-infected patients (n = 18) and uninfected individuals (n = 20). EV-derived miRNAs were then prepared and abundance of hsa-miR-15b-5p, hsa-miR-16-5p, hsa-let-7a-5p and hsa-miR-150-5p was assessed in these samples. Quantitative polymerase chain reaction was performed, and relative expression of each miRNA was calculated using hsa-miR-451a as endogenous control. Then, the targets of up-regulated miRNAs and relevant pathways were predicted by using bioinformatics. Receiver Operating Characteristic with Area under the Curve (AUC) was then calculated to assess their diagnostic potential. RESULTS: The relative expression of hsa-miR-150-5p and hsa-miR-15b-5p was higher in P. vivax-infected patients compared to uninfected individuals, but hsa-let-7a-5p was up-regulated in both P. vivax-infected patients and P. falciparum-infected patients. Bioinformatic analysis revealed that these miRNAs might regulate genes involved in the malaria pathway including the adherens junction and the transforming growth factor-ß pathways. All up-regulated miRNAs could potentially be used as disease biomarkers as determined by AUC; however, the sensitivity and specificity require further investigation. CONCLUSION: An upregulation of hsa-miR-150-5p and hsa-miR-15b-5p was observed in P. vivax-infected patients while hsa-let-7a-5p was up-regulated in both P. vivax-infected and P. falciparum-infected patients. These findings will require further validation in larger cohort groups of malaria patients to fully understand the contribution of these EVs miRNAs to malaria detection and biology.

PURPOSE: To investigate whether age-related macular degeneration (AMD) has an influence on the prevalence and anatomical characteristics of lamellar macular holes (LMHs). METHODS: Clinical records and spectral-domain optical coherence tomography images of 756 eyes of 423 consecutive patients diagnosed with AMD were reviewed and analyzed. Spectral-domain optical coherence tomography was used to identify degenerative or tractional LMH subtypes and assess their morphology. The clinical and optical coherence tomography findings of AMD eyes with LMH were compared with those of a control group of eyes with LMH without AMD from a previously published report. RESULTS: Lamellar macular holes were identified in 25 eyes of 23 patients (3.3%; 25 of 756). Seventeen of 25 eyes (68%) presented with degenerative LMH and underlying late neovascular AMD. Mean best-corrected visual acuity was worse in eyes with AMD and LMH eyes than in those with AMD and no LMH (20/230 vs. 20/98; P = 0.02). The mean outer diameter was greater in the group with degenerative LMH with concomitant AMD than in the control group of degenerative LMH without AMD (1,323.9 ± 999.1 µm vs. 905.9 ± 356.8 µm, respectively; P = 0.01). CONCLUSION: The incidence of degenerative LMH increased in advanced forms of AMD, whereas the presence of tractional LMH subtype may be unrelated to AMD evolution.

Background Asian Americans are often seen as a model minority; however, the group faces significant cultural, language, and financial barriers to adequate health care access. Assessing health insurance's impact on cardiovascular disease risk factors among older Asian Americans may provide support for further research and intervention development focused on improving insurance enrollment. The authors sought to examine the associations between elevated blood pressure and body mass index and insurance coverage. Methods Individuals attended health fairs held by a student-led organization in Southern California between 2008 and 2011. Age and insurance status were obtained through participant questionnaires. Participants' blood pressure and body mass index were measured. Analyses identified health and insurance associations. Results In total, 53.8% of respondents were 60 years or older. Of these, 30.9% had an elevated blood pressure and 36.6% had an elevated body mass index. Of respondents 60 years or older, 52.0% had health insurance. Both elevated blood pressure (p = 0.04) and body mass index (p = 0.03) were significantly associated with lacking insurance. Conclusions Insured participants were less likely to have elevated blood pressure and body mass index measurements, supporting a positive correlation between having insurance and less risk factors for cardiovascular disease. These findings provide incentives for further research into the importance of health insurance in preventative health care.
RESUMEN
Studies show that physical exercise (PE) is associated with a reduced fat accumulation and increased insulin sensitivity, and taurine (TAU) improves glucose homeostasis in lean rodents. The aim in this work was evaluate the effects of supplementing TAU and practice of PE, associated or not, on obesity and glucose homeostasis on obese MSG-mice. Neonate male Swiss mice received injections of monosodium glutamate (MSG group) or saline (CON group). From the 30th to the 90th day of life, one group of animals received TAU in drinking water (MSG TAU group), another was subjected to PE (MSG PE group) and a third group underwent both procedures (MSG PE TAU group). Mice treated with MSG become obese, hypertriglyceridemic, glucose intolerant and insulin resistant. The supplementation with TAU and the PE, isolated or associated, reduced the triglycerides (38%), glucose intolerance (around 30%) and KITT (79%) in MSG-obese animals, but did not influence the accumulation of fat. Interestingly, the combination of both strategies significantly reduced the insulin resistance, compared to animals subjected to isolated strategies. In conclusion, the supplementation with TAU and PE, isolated or associated, did not influence the accumulation of fat in MSG-obese mice, however, reduce the triglycerides and insulin resistance.
O exercício físico (EF) está associado à redução do acúmulo de gordura e aumento na sensibilidade à insulina e a taurina (TAU) melhora a homeostase glicêmica em roedores magros. Objetivou-se avaliar os efeitos da suplementação com TAU e do EF, associados ou não, sobre a obesidade e a homeostase glicêmica em camundongos obesos-MSG. Camundongos Swiss machos neonatos receberam injeções de glutamato monossódico (grupo MSG) ou salina (grupo CON). Do 30º ao 90º dia de vida, um grupo de animais MSG recebeu TAU na água de beber (MSG TAU); outro foi submetido ao EF (MSG EX) e um terceiro grupo foi submetido aos dois procedimentos (MSG EX TAU). Camundongos -MSG tornaram-se obesos, hipertrigliceridêmicos, intolerantes à glicose e resistentes à insulina. A suplementação com TAU e o EF, associados ou isolados, reduziram a trigliceridemia (38%), a intolerância à glicose (30%) e o KITT (79%) nos animais obesos-MSG, porém, não influenciaram o acúmulo de gordura. A associação das duas estratégias diminui significativamente a resistência à insulina, comparado aos animais submetidos às estratégias isoladas. Conclui-se que a suplementação com TAU e o EF, associados ou isolados, não influenciam no acúmulo de gordura dos camundongos obesos-MSG, porém, diminuem a trigliceridemia e a resistência à insulina.
