Comorbidities and use of health services in people with diabetes mellitus according to risk levels by adjusted morbidity groups.

BACKGROUND: People with diabetes mellitus frequently have other comorbidities and involve greater use of primary and hospital care services. The aim of this study was to describe the comorbidities and use of primary and hospital care services of people with diabetes according to their risk level by adjusted morbidity groups (AMG) and to analyse the factors associated with the utilisation of these services. METHODS: Cross-sectional study. People with diabetes were identified within the population of patients with chronic conditions of an urban health care centre by the AMG stratification tool integrated into the primary health care electronic clinical record of the Community of Madrid. Sociodemographic, functional, clinical characteristics and annual health care services utilisation variables were collected. Univariate, bivariate and Poisson regression analyses were performed. RESULTS: A total of 1,063 people with diabetes were identified, representing 10.8% of patients with chronic conditions within the health centre. A total of 51.4% were female, the mean age was 70 years, 94.4% had multimorbidity. According to their risk level, 17.8% were high-risk, 40.6% were medium-risk and 41.6% were low-risk. The most prevalent comorbidities were hypertension (70%), dyslipidaemia (67%) and obesity (32.4%). Almost 50% were polymedicated. Regarding health services utilisation, 94% were users of primary care, and 59.3% were users of hospital care. Among the main factors associated with the utilisation of both primary and hospital care services were AMG risk level and complexity index. In primary care, utilisation was also associated with the need for primary caregivers, palliative care and comorbidities such as chronic heart failure and polymedication, while in hospital care, utilisation was also associated with comorbidities such as cancer, chronic obstructive pulmonary disease or depression. CONCLUSIONS: People with diabetes were older, with important needs for care, many associated comorbidities and polypharmacy that increased in parallel with the patient's risk level and complexity. The utilisation of primary and hospital care services was very high, being more frequent in primary care. Health services utilization were principally associated with functional factors related to the need of care and with clinical factors such as AMG medium and high-risk level, more complexity index, some serious comorbidities and polymedication.

Crystal structure of the class A extended-spectrum ß-lactamase CTX-M-96 in complex with relebactam at 1.03 Angstrom resolution.

The use of ß-lactam/ß-lactamase inhibitors constitutes an important strategy to counteract ß-lactamases in multidrug-resistant (MDR) Gram-negative bacteria. Recent reports have described ceftazidime-/avibactam-resistant isolates producing CTX-M variants with different amino acid substitutions (e.g., P167S, L169Q, and S130G). Relebactam (REL) combined with imipenem has proved very effective against Enterobacterales producing ESBLs, serine-carbapenemases, and AmpCs. Herein, we evaluated the inhibitory efficacy of REL against CTX-M-96, a CTX-M-15-type variant. The CTX-M-96 structure was obtained in complex with REL at 1.03 Å resolution (PDB 8EHH). REL was covalently bound to the S70-Oγ atom upon cleavage of the C7-N6 bond. Compared with apo CTX-M-96, binding of REL forces a slight displacement of the deacylating water inwards the active site (0.81 Å), making the E166 and N170 side chains shift to create a proper hydrogen bonding network. Binding of REL also disturbs the hydrophobic patch formed by Y105, P107, and Y129, likely due to the piperidine ring of REL that creates clashes with these residues. Also, a remarkable change in the positioning of the N104 sidechain is also affected by the piperidine ring. Therefore, differences in the kinetic behavior of REL against class A ß-lactamases seem to rely, at least in part, on differences in the residues being involved in the association and stabilization of the inhibitor before hydrolysis. Our data provide the biochemical and structural basis for REL effectiveness against CTX-M-producing Gram-negative pathogens and essential details for further DBO design. Imipenem/REL remains an important choice for dealing with isolates co-producing CTX-M with other ß-lactamases.

Endoplasmic reticulum exit sites are segregated for secretion based on cargo size.

TANGO1, TANGO1-Short, and cTAGE5 form stable complexes at the endoplasmic reticulum exit sites (ERES) to preferably export bulky cargoes. Their C-terminal proline-rich domain (PRD) binds Sec23A and affects COPII assembly. The PRD in TANGO1-Short was replaced with light-responsive domains to control its binding to Sec23A in U2OS cells (human osteosarcoma). TANGO1-ShortΔPRD was dispersed in the ER membrane but relocated rapidly, reversibly, to pre-existing ERES by binding to Sec23A upon light activation. Prolonged binding between the two, concentrated ERES in the juxtanuclear region, blocked cargo export and relocated ERGIC53 into the ER, minimally impacting the Golgi complex organization. Bulky collagen VII and endogenous collagen I were collected at less than 47% of the stalled ERES, whereas small cargo molecules were retained uniformly at almost all the ERES. We suggest that ERES are segregated to handle cargoes based on their size, permitting cells to traffic them simultaneously for optimal secretion.

Adolescent health-risk behaviours in Uruguay: Patterns from national cross-sectional school surveys conducted in 2006, 2012 and 2019.

BACKGROUND: There are no trend studies on various health risk behaviours among adolescents in Uruguay. Therefore, this study looked at trends in a number of health-risky behaviours among adolescents in Uruguay from three separate surveys. METHODS: Data from 9272 adolescents (age range: 11-16 years), who took part in three cross-sectional national in-school surveys in Uruguay in 2006, 2012 and 2019 were analysed. A self-administered survey was used to evaluate 24 health risk behaviours. By using logistic regression analyses to treat the study year as a categorical variable and adjusting food insecurity and age, linear trends were examined. RESULTS: We found a significant increase in the prevalence of being overweight, having obesity, inadequate fruit intake, sedentary behaviour in leisure-time, physical inactivity, bullying victimisation, loneliness, suicidal ideation, and sexual activity. We found a significant decrease in current cigarette use, physical fighting and current alcohol use. Among males, a significant increase of non-condom use, and a decrease in current other tobacco use (other than cigarettes), being physically attacked and the number of sexual partners. Among females, we found an increase in food insecurity, trouble from alcohol use, multiple sexual partners, and sleep problems. CONCLUSION: Overall, from 2006 to 2019, there was a decrease in seven health risk behaviours among boys and/or girls. Among boys, there was an increase in 10 health risk behaviours and among girls, 15 health risk behaviours increased, highlighting adolescent girls' greater vulnerability, thereby perpetuating further gendered health inequalities. In Uruguay, school health programmes for adolescents are recommended.

Implications of sedation during the use of noninvasive ventilation in children with acute respiratory failure (SEDANIV Study).

BACKGROUND: The objective of this study was to analyze the effects of sedation administration on clinical parameters, comfort status, intubation requirements, and the pediatric intensive care unit (PICU) length of stay (LOS) in children with acute respiratory failure (ARF) receiving noninvasive ventilation (NIV). METHODS: Thirteen PICUs in Spain participated in a prospective, multicenter, observational trial from January to December 2021. Children with ARF under the age of five who were receiving NIV were included. Clinical information and comfort levels were documented at the time of NIV initiation, as well as at 3, 6, 12, 24, and 48 h. The COMFORT-behavior (COMFORT-B) scale was used to assess the patients' level of comfort. NIV failure was considered to be a requirement for endotracheal intubation. RESULTS: A total of 457 patients were included, with a median age of 3.3 months (IQR 1.3-16.1). Two hundred and thirteen children (46.6%) received sedation (sedation group); these patients had a higher heart rate, higher COMFORT-B score, and lower SpO2/FiO2 ratio than did those who did not receive sedation (non-sedation group). A significantly greater improvement in the COMFORT-B score at 3, 6, 12, and 24 h, heart rate at 6 and 12 h, and SpO2/FiO2 ratio at 6 h was observed in the sedation group. Overall, the NIV success rate was 95.6%-intubation was required in 6.1% of the sedation group and in 2.9% of the other group (p = 0.092). Multivariate analysis revealed that the PRISM III score at NIV initiation (OR 1.408; 95% CI 1.230-1.611) and respiratory rate at 3 h (OR 1.043; 95% CI 1.009-1.079) were found to be independent predictors of NIV failure. The PICU LOS was correlated with weight, PRISM III score, respiratory rate at 12 h, SpO2 at 3 h, FiO2 at 12 h, NIV failure and NIV duration. Sedation use was not found to be independently related to NIV failure or to the PICU LOS. CONCLUSIONS: Sedation use may be useful in children with ARF treated with NIV, as it seems to improve clinical parameters and comfort status but may not increase the NIV failure rate or PICU LOS, even though sedated children were more severe at technique initiation in the present sample.

Synthesis and Properties of Hydrophilic and Hydrophobic Deep Eutectic Solvents via Heating-Stirring and Ultrasound.

Deep eutectic solvents (DESs) have emerged as a greener alternative to other more polluting traditional solvents and have attracted a lot of interest in the last two decades. The DESs are less toxic dissolvents and have a lower environmental footprint. This paper presents an alternative synthesis method to the classical heating-stirring method. The ultrasound method is one of the most promising synthesis methods for DESs in terms of yield and energy efficiency. Therefore, the ultrasound synthesis method was studied to obtain hydrophobic (Aliquat 336:L-Menthol (3:7); Lidocaine:Decanoic acid (1:2)) and hydrophilic DESs based on choline chloride, urea, ethylene glycol and oxalic acid. The physical characterization of DESs via comparison of Fourier transform infrared (FTIR) spectra showed no difference between the DESs obtained by heating-stirring and ultrasound synthesis methods. The study and comparison of all the prepared DESs were carried out via nuclear magnetic resonance spectroscopy (NMR). The density and viscosity properties of DESs were evaluated. The density values were similar for both synthesis methods. However, differences in viscosity values were detected due to the presence of some water in hygroscopic DESs.

Response-Adapted Ultralow-Dose Radiation Therapy for Orbital Indolent B-Cell Lymphoma: A Phase 2 Nonrandomized Controlled Trial.

Importance: Radiation therapy to doses of 24 to 36 Gy is currently used to treat indolent B-cell lymphoma of the ocular adnexa; however, ocular adverse effects are common. Objective: To determine if a response-adapted radiation therapy strategy will result in excellent disease outcomes while reducing orbital morbidity. Design, Setting, and Participants: This single-institution, phase 2 prospective nonrandomized controlled trial of a response-adapted strategy involved 50 evaluable patients with stage I to IV indolent B-cell lymphoma of the ocular adnexa enrolled between July 2015 and January 2021. This treatment approach was also retrospectively evaluated with a separate 55-patient cohort treated between March 2013 and October 2021. All data were analyzed between November 2021 and December 2023. Interventions: Patients were treated with ultralow-dose radiation therapy to 4 Gy in 2 fractions and assessed for response at 3-month intervals. Patients with persistent orbital lymphoma were offered an additional 20 Gy in 10 fractions to complete the response-adapted treatment. Main Outcome and Measures: The primary end point was 2-year local orbital control within the irradiated field after response-adapted therapy. Secondary end points included overall survival and complete response rate. Results: The 50 prospective patients were a median (range) of 63 (29-88) years old, and 31 (62%) were female. Among the 50 patients, 32 (64%) had mucosa-associated lymphoid tissue lymphoma, 12 (24%) had follicular lymphoma, and 6 (12%) had unclassifiable low-grade B-cell lymphoma. Thirty-one patients (62%) had stage I disease, and 36 (72%) were newly diagnosed. At a median follow-up of 37.4 (95% CI, 33.7-52.5) months, the 2-year local control rate was 89.4% (95% CI, 81.0%-98.7%), and the 2-year overall survival rate was 98.0% (95% CI, 94.1%-100%); 45 patients (90.0%; 95% CI, 78.2%-96.7%) experienced a complete response to response-adapted radiation, including 44 patients with a complete response to ultralow-dose radiation and 1 patient with a complete response after an additional 20 Gy. No local recurrences were observed among patients with a complete response to response-adapted therapy. No grade 3 or higher toxic effects were observed. In a planned subset analysis of 22 patients with newly diagnosed, untreated stage I mucosa-associated lymphoid tissue lymphoma, the 2-year local control rate was 90.7% (95% CI, 79.2%-100%), and the 2-year freedom from distant relapse rate was 95.2% (95% CI, 86.6%-100%). Conclusion and Relevance: In this nonrandomized controlled trial, response-adapted ultralow-dose therapy for indolent orbital B-cell lymphoma resulted in reduced radiation exposure, negligible toxic effects, and excellent disease outcomes. Trial Registration: ClinicalTrials.gov Identifier: NCT02494700.

JRK binds satellite III DNA and is necessary for the heat shock response.

JRK is a DNA-binding protein of the pogo superfamily of transposons, which includes the well-known centromere binding protein B (CENP-B). Jrk null mice exhibit epilepsy, and growth and reproductive disorders, consistent with its relatively high expression in the brain and reproductive tissues. Human JRK DNA variants and gene expression levels are implicated in cancers and neuropsychiatric disorders. JRK protein modulates ß-catenin-TCF activity but little is known of its cellular functions. Based on its homology to CENP-B, we determined whether JRK binds centromeric or other satellite DNAs. We show that human JRK binds satellite III DNA, which is abundant at the chromosome 9q12 juxtacentromeric region and on Yq12, both sites of nuclear stress body assembly. Human JRK-GFP overexpressed in HeLa cells strongly localises to 9q12. Using an anti-JRK antiserum we show that endogenous JRK co-localises with a subset of centromeres in non-stressed cells, and with heat shock factor 1 following heat shock. Knockdown of JRK in HeLa cells proportionately reduces heat shock protein gene expression in heat-shocked cells. A role for JRK in regulating the heat shock response is consistent with the mouse Jrk null phenotype and suggests that human JRK may act as a modifier of diseases with a cellular stress component.

Oligodendrocyte-specific expression of PSG8-AS1 suggests a role in myelination with prognostic value in oligodendroglioma.

The segmentally duplicated Pregnancy-specific glycoprotein (PSG) locus on chromosome 19q13 may be one of the most rapidly evolving in the human genome. It comprises ten coding genes (PSG1-9, 11) and one predominantly non-coding gene (PSG10) that are expressed in the placenta and gut, in addition to several poorly characterized long non-coding RNAs. We report that long non-coding RNA PSG8-AS1 has an oligodendrocyte-specific expression pattern and is co-expressed with genes encoding key myelin constituents. PSG8-AS1 exhibits two peaks of expression during human brain development coinciding with the most active periods of oligodendrogenesis and myelination. PSG8-AS1 orthologs were found in the genomes of several primates but significant expression was found only in the human, suggesting a recent evolutionary origin of its proposed role in myelination. Additionally, because co-deletion of chromosomes 1p/19q is a genomic marker of oligodendroglioma, expression of PSG8-AS1 was examined in these tumors. PSG8-AS1 may be a promising diagnostic biomarker for glioma, with prognostic value in oligodendroglioma.

AC-ASPECTS, ACh-ASPECTS, and H-ASPECTS: new imaging scales to assess territorial and total cerebral hemispheric ischemic injury.

Background: The extent of ischemic injury in acute stroke is assessed in clinical practice using the Acute Stroke Prognosis Early CT Score (ASPECTS) rating system. However, current ASPECTS semi-quantitative topographic scales assess only the middle cerebral artery (MCA) (original ASPECTS) and posterior cerebral (PC-ASPECTS) territories. For treatment decision-making in patients with anterior cerebral artery (ACA) occlusions and internal carotid artery (ICA) occlusions with large ischemic cores, measures of all hemispheric regions are desirable. Methods: In this cohort study, anatomic rating systems were developed for the anterior cerebral (AC-ASPECTS, 3 points) and anterior choroidal artery (ACh-ASPECTS, 1 point) territories. In addition, a total supratentorial hemisphere (H-ASPECTS, 16 points) score was calculated as the sum of the MCA ASPECTS (10 regions), supratentorial PC-ASPECTS (2 regions), AC-ASPECTS (3 regions), and ACh-ASPECTS (1 region). Three raters applied these scales to initial and 24 h CT and MR images in consecutive patients with ischemic stroke (IS) due to ICA, M1-MCA, and ACA occlusions. Results: Imaging ratings were obtained for 96 scans in 50 consecutive patients with age 74.8 (±14.0), 60% female, NIHSS 15.5 (9.25-20), and occlusion locations ICA 34%; M1-MCA 58%; and ACA 8%. Treatments included endovascular thrombectomy +/- thrombolysis in 72%, thrombolysis alone in 8%, and hemicraniectomy in 4%. Among experienced clinicians, inter-rater reliability for AC-, ACh-, and H-ASPECTS scores was substantial (kappa values 0.61-0.80). AC-ASPECTS abnormality was present in 14% of patients, and ACh-ASPECTS abnormality in 2%. Among patients with ACA and ICA occlusions, H-ASPECTS scores compared with original ASPECTS scores were more strongly associated with disability level at discharge, ambulatory status at discharge, discharge destination, and combined inpatient mortality and hospice discharge. Conclusion: AC-ASPECTS, ACh-ASPECTS, and H-ASPECTS expand the scope of acute IS imaging scores and increase correlation with functional outcomes. This additional information may enhance prognostication and decision-making, including endovascular thrombectomy and hemicraniectomy.

Correlation of EUS-guided portal pressure gradient measurements with hepatic venous pressure gradient: a prospective study.

BACKGROUND AND AIMS: Hepatic Venous Portal Gradient (HVPG) measurement remains the gold standard for estimating portal pressure gradient (PPG). AIM: To evaluate the correlation between EUS-guided portal pressure gradient (EUS-PPG) and HVPG in patients with chronic portal hypertension. PATIENTS AND METHODS: Patients with chronic portal hypertension in whom HVPG assessment was clinically indicated were invited to undergo transjugular HVPG and EUS-PPG with a 22G needle in separate sessions for comparison. Intra-class correlation coefficient (ICC), and Bland-Altman method were used to evaluate the agreement between techniques. RESULTS: 33 patients were included. No significant differences in technical success were observed: EUS-PPG (31/33, 93.9%) vs. HVPG (31/33, 93.9%). Thirty patients who underwent successful EUS-PPG and HVPG were analysed. Correlation between the two techniques showed an ICC: 0.82(0.65-0.91). Four patients had major discrepancies (≥ 5 mmHg) between HVPG and EUS-PPG. No significant differences in adverse events were observed. CONCLUSIONS: The correlation between EUS-PPG and HVPG was almost perfect. EUS-PPG could be a safe and reliable method for direct PPG measurement in cirrhotic patients and a valid alternative to HVPG. NCT05689268.

Unraveling chromosomal and genotoxic damage in individuals occupationally exposed to coal from underground mining.

Purpose: Coal mining is a vital sector in Colombia, contributing significantly to the nation's economy and the development of its regions. However, despite its importance, it has led to a gradual decline in the health of mine workers and nearby residents. While the adverse health effects of open-pit coal mining on exposed individuals have been well-documented in Colombia and globally, studies investigating genetic damage in underground coal miners are lacking. Methods: The aim of our study was to evaluate chromosomal and genotoxic damage, in peripheral blood samples from a group of underground coal miners and residents of areas exposed to coal, in the town of Samacá, Boyacá-Colombia, and in a group of unexposed individuals by using banding and molecular cytogenetic techniques, as well as cytokinesis block micronucleus assays. Results: Our results suggest that occupational exposure to coal induces chromosomal and genotoxic damage in somatic cells of underground coal miners. Chromosomal and genotoxic damage is an important step in carcinogenesis and the development of many other diseases. Our findings provide valuable insights into the effects of coal dust exposure on chromosomal integrity and genetic stability. Conclusion: Our pilot study suggests that occupational exposure to coal induces chromosomal damage in underground coal miners, highlighting the importance of validating these findings with a larger sample size. Our results highlight the need to implement prevention and protection measures, as well as educational programs for underground coal miners. Characterizing and estimating exposure risks are extremely important for the safety of people exposed occupationally and environmentally to coal and its derivatives.

Wet steam method for reducing attached cells of Salmonella and Listeria monocytogenes on Hass avocado.

The consumption of avocados and their products has been linked to outbreaks of illness caused by Salmonella enterica and Listeria monocytogenes. These pathogens have been isolated from avocados collected from farms and markets. After contact with the avocado epicarp, the cells of Salmonella and L. monocytogenes can become loosely attached (LA) by suspension in a film of water and attraction by electrostatic forces, or strongly attached (SA) by physical and irreversible attachment mechanisms. Attached cells may have greater resistance to agents used to decontaminate the fruit. The effect of applying wet steam (WS) to the epicarp of Hass avocados on the reduction LA and SA counts of Salmonella and L. monocytogenes was evaluated as a function of the exposure time. The inoculated avocados were washed and exposed to WS for 30, 45, and 60 s inside a treatment chamber. Salmonella was found to be more susceptible to WS than L. monocytogenes. The efficacy of steam in reducing LA and SA cell numbers was similar for both pathogens. Steaming avocados for 60 s reduced LA Salmonella and L. monocytogenes cells by 4.6 and 4.8 log CFU/avocado, whereas SA cells were decreased by 5.2 and 4.4 log CFU/avocado, respectively.•Steaming the avocados for 60 s produced the greatest reduction in loosely and strongly attached cells for both pathogens.•Wet steam treatment efficiently eliminated the loosely and strongly attached cells of both pathogens.•The Listeria monocytogenes attached cells showed greater resistance to steam treatment than Salmonella.

Workplace health promotion programs: The role of compliance with workers' expectations, the reputation and the productivity of the company.

INTRODUCTION: Addressing the health and safety of workers is key to achieving Sustainable Development Goals 3 and 8. The European Union urges companies in its member countries to promote measures in this regard. However, this type of program is not a general approach in European companies. This study aims to identify whether the implementation of Workplace Health Promotion measures is influenced by the company's desire to meet its employees' expectations in this area; and if this relationship involves the company's reputation and productivity. METHODS: A multi-step methodology is used (descriptive sample portrait, analysis of influences by linear regression, and double-intermediation model analysis) to find out if reputation and productivity mediate the relationship between the satisfaction of employee health expectations and the number of Workplace Health Promotion measures applied. RESULTS: The more weight the company gives to this compliance, the more motivated it is to implement a more significant number of Workplace Health Promotion measures. The increase in productivity does not seem to weigh in this relationship, but the improvement of the company's reputation does. CONCLUSIONS: The more the employees' expectations of working in a healthy company are desired to be met, the more measures the company will put in place. PRACTICAL APPLICATIONS: The findings have theoretical implications, by increasing knowledge about the factors that influence a company's decision to activate Workplace Health Promotion policies. They can also serve as guidance for implementing policies that encourage health promotion in companies and contribute to the achievement of Sustainable Development Goals 3 and 8: for workers' representatives, by better understanding how these factors influence the fulfillment of their constituents' expectations; for company managers, by better knowing the variables involved in this relationship; and for researchers of this topic.

The Effects of Slaughter Methods and Drying Temperatures on the Protein Hydrolysis of Black Soldier Fly Larvae Meal.

In recent years, the potential of insects as a sustainable protein alternative to feed the growing world population has been explored. Differences in the ways insects are processed can affect their proximate composition and digestibility. This work studied the effects of the combination of different types of slaughter methods and drying temperatures on the proximate composition, organic matter digestibility (OMd), hydrolysis degree (DH/NH2 and DH/100 g DM), total hydrolysis (TH), and hygienic and sanitary characteristics of BSFL (black soldier fly larvae) meal. Four types of slaughter methods were used including freezing (F), blanching + freezing (B), Melacide® + freezing (M), and liquid nitrogen slaughter (N). Each of these was used with three drying temperatures (50, 70, and 90 °C). A negative correlation between the acid detergent fiber (ADF) and protein digestibility parameters was obtained. The most suitable drying temperature was 70 °C, as it produced higher values of protein digestibility (DH and TH), resulting in hygienic and sanitary conditions suitable for food use. Slaughtering with liquid nitrogen and blanching was more conducive to achieving high protein digestibility results than traditional freezing or the use of Melacide®.

Bordetella pertussis outer membrane vesicles impair neutrophil bactericidal activity.

Neutrophils constitute the primary defense against bacterial infections, yet certain pathogens express virulence factors that enable them to subvert neutrophils-mediated killing. Outer membrane vesicles (OMVs) have emerged as a secretory system through which bacteria deliver virulence factors to host cells. OMVs from Bordetella pertussis, the etiological agent of whooping cough, are loaded with most of bacterial virulence factors, including CyaA, which plays a key role in B. pertussis evasion of neutrophils bactericidal activity. In our study, we investigated the role of B. pertussis OMVs in bacterial interaction with neutrophils. We observed that interaction of OMVs with neutrophils led to a decrease in the expression of cell surface CR3 and FcγRs, an effect dependent on the CyaA toxin delivered by these vesicles. This decreased receptor expression led to reduced bacterial uptake by neutrophils, irrespective of the presence of opsonic antibodies. Moreover, CyaA delivered by OMVs hindered intracellular bactericidal trafficking, promoting bacterial intracellular survival. When both bacteria and OMVs were opsonized, competition between opsonized OMVs and B. pertussis for FcγRs on neutrophils led to a significant decrease in bacterial uptake. Overall, our findings suggest that B. pertussis OMVs promote bacterial survival to the encounter with neutrophils in both naïve and immunized individuals.

Decomposition analysis of racial and ethnic differences in receipt of immediate postpartum, long-acting, reversible, and permanent contraception.

OBJECTIVES: This study aimed to determine the factors contributing to racial and ethnic disparities in the use of immediate postpartum, long-acting reversible contraception (IPP LARC) and permanent contraception among Medicaid recipients. STUDY DESIGN: We conducted a cross-sectional study using 3 years of national Medicaid claims data to examine the rates of IPP LARC use alone and a composite measure of postpartum permanent contraception and IPP LARC within 7 days of delivery by race and ethnicity. We used a Blinder-Oaxaca model to quantify the extent to which medical complexity, age, rurality, mode of delivery, and year explained differences in outcomes among different minoritized groups in comparison to non-Hispanic White women. RESULTS: Our study sample contained 1,729,663 deliveries occurring from 2016 through 2018 among 1,605,199 people living in 16 states. IPP LARC use rates were highest among Black (2.2%), followed by American Indian and Alaska Native at 2.1% and Hawaiian/Pacific Islander beneficiaries at 1.9%, Hispanic (all races) at 1.2%, and Asian at 1.0%. IPP LARC was lowest among White beneficiaries (0.8%). Medical complexity, age, rurality, year, and mode of delivery explained only 12.3% of the difference in IPP LARC rates between Black and White beneficiaries. Postpartum permanent contraception was highest among White (7.6%), Hispanic (7.2%), and American Indian and Alaska Native (6.8%), followed by Black (6.3%), Hawaiian/Pacific Islander (5.1%) and lowest among Asian women (4.1%). When we examined the use of IPP LARC or postpartum permanent contraception together, these same factors explained 94.4% of the differences between Black and White beneficiaries. CONCLUSIONS: While differences in the use of IPP LARC by race and ethnicity were identified, our findings suggest that overall use of inpatient highly effective contraception are similar across racial and ethnic groups. IMPLICATIONS: When IPP LARC and postpartum permanent contraception are examined jointly, their use is similar across racial and ethnic groups.

Cancer is not a risk factor for severe COVID-19 in children, except in patients with recent allogeneic hematopoietic stem cell transplantation or comorbidities.

The EPICO (Spanish general registry of COVID-19 in children)-SEHOP (Spanish Society of Pediatric Hematology and Oncology) platform gathers data from children with SARS-CoV-2 in Spain, allowing comparison between children with cancer or allogeneic hematopoietic stem cell transplantation (alloHSCT) and those without. The infection is milder in the cancer/alloHSCT group than in children without comorbidities (7.1% vs. 14.7%), except in children with recent alloHSCT (less than 300 days), of which 35.7% experienced severe COVID-19. These data have been shared with the SEHOP members to support treatment and isolation policies akin to those for children without cancer, except for those with recent alloHSCT or additional comorbidities. This highlights the collaborative registries potential in managing pandemic emergencies.

Persistence, effectiveness and safety of ustekinumab and vedolizumab therapy for complex perianal fistula in Crohn's disease: The HEAL study from GETECCU.

BACKGROUND: The efficacy of ustekinumab and vedolizumab for treating complex perianal fistula in Crohn's disease has been barely studied. We aimed to assess treatment persistence, clinical remission, and safety of these drugs in this context. METHODS: Crohn's disease patients who had received ustekinumab or vedolizumab for the indication of active complex perianal fistula, were included. Clinical remission was defined according to Fistula Drainage Assessment Index (no drainage through the fistula upon gentle pressure) based on physicians' assessment. RESULTS: Of 155 patients, 136 received ustekinumab, and 35 vedolizumab (16 received both). Median follow-up for ustekinumab was 27 months. Among those on ustekinumab, 54 % achieved remission, and within this group, 27 % relapsed during follow-up. The incidence rate of relapse was 11 % per patient-year. Multivariate analysis found no variables associated with treatment discontinuation or relapse. Median follow-up time for patients receiving vedolizumab was 19 months. Remission was achieved in 46 % of the patients receiving vedolizumab, and among them, 20 % relapsed during follow-up. The incidence rate of relapse was 7 % per patient-year. Adverse events were mild in 6 % on ustekinumab and 8 % on vedolizumab. CONCLUSION: Ustekinumab and vedolizumab appear effective, achieving remission in around half of complex perianal fistula patients, with favorable safety profiles.

Medicaid Policy Change and Immediate Postpartum Long-Acting Reversible Contraception.

Importance: Improving access to the choice of postpartum contraceptive methods is a national public health priority, and the need is particularly acute within the Medicaid population. One strategy to ensure individuals have access to the full range of contraceptive methods is the provision of a method prior to hospital discharge following a birth episode. Beginning in 2016, some states changed their Medicaid billing policy, allowing separate reimbursement for intrauterine devices and contraceptive implants to increase the provision of long-acting reversible contraceptive (LARC) methods immediately postpartum (IPP). Objective: To assess the association of a change in Medicaid billing policy with use of IPP LARC. Design, Setting, and Participants: The cohort study of postpartum Medicaid recipients in 9 treatment and 6 comparison states was conducted from January 2016 to October 2019. Data were analyzed from August 2023 to January 2024. Main Outcomes and Measures: The primary outcome was use of IPP LARC. Results: The final sample included 1 378 885 delivery encounters for 1 197 287 Medicaid enrollees occurring in 15 states. Mean age of beneficiaries at delivery was 27 years. The IPP LARC billing policy was associated with a mean increase of 0.74 percentage points (95% CI, 0.30-1.18 percentage points) in the immediate receipt of IPP LARC, with a prepolicy baseline rate of 0.54%. The IPP LARC billing policy was also associated with an overall increase of 1.48 percentage points (95% CI, 0.43-2.73 percentage points) in LARC use by 60 days post partum. Conclusions and Relevance: In this cohort study, changing Medicaid billing policy to allow for separate reimbursement of LARC devices from the global fee was associated with increased use of IPP LARC, suggesting that this may be a strategy to improve access to the full range of postpartum contraceptive methods.
