Polygenic risk score of metabolic dysfunction-associated steatotic liver disease amplifies the health impact on severe liver disease and metabolism-related outcomes

BackgroundAlthough the inherited risk factors associated with fatty liver disease are well understood, little is known about the genetic background of metabolic dysfunction-associated steatotic liver disease (MASLD) and its related health impacts. Compared to non-alcoholic fatty liver disease (NAFLD), MASLD presents significantly distinct diagnostic criteria, and epidemiological and clinical features, but the related genetic variants are yet to be investigated. Therefore, we conducted this study to assess the genetic background of MASLD and interactions between MASLD-related genetic variants and metabolism-related outcomes.MethodsParticipants from the UK Biobank were grouped into discovery and replication cohorts for an MASLD genome-wide association study (GWAS), and base and target cohorts for polygenic risk score (PRS) analysis. Autosomal genetic variants associated with NAFLD were compared with the MASLD GWAS results. Kaplan–Meier and Cox regression analyses were used to assess associations between MASLD and metabolism-related outcomes.ResultsSixteen single-nucleotide polymorphisms (SNPs) were identified at genome-wide significance levels for MASLD and duplicated in the replication cohort. Differences were found after comparing these SNPs with the results of NAFLD-related genetic variants. MASLD cases with high PRS had a multivariate-adjusted hazard ratio of 3.15 (95% confidence interval, 2.54–3.90) for severe liver disease (SLD), and 2.81 (2.60–3.03) for type 2 diabetes mellitus. The high PRS amplified the impact of MASLD on SLD and extrahepatic outcomes.ConclusionsHigh PRS of MASLD GWAS amplified the impact of MASLD on SLD and metabolism-related outcomes, thereby refining the process of identification of individuals at high risk of MASLD. Supplementation of this process with relevant genetic backgrounds may lead to more effective MASLD prevention and management.

Preliminarily exploring the intraoperative ultrasonography characteristics of patients with degenerative cervical myelopathy

BackgroundHow to quickly read and interpret intraoperative ultrasound (IOUS) images of patients with degenerative cervical myelopathy (DCM) to obtain meaningful information? Few studies have systematically explored this topic.PurposeTo systematically and comprehensively explore the IOUS characteristics of patients with DCM.Materials and methodsThis single-center study retrospectively included patients with DCM who underwent French-door laminoplasty (FDL) with IOUS guidance from October 2019 to March 2022. One-way ANOVA and Pearson’s /Spearman’s correlation analysis were used to analyze the correlations between the cross-sectional area of the spinal cord (SC) and individual characteristics; the relationships between the morphology, echogenicity, pulsation, decompression statuses, compression types of SC, location of the spinal cord central echo complex (SCCEC) and the disease severity (the preoperative Japanese Orthopedic Association score, preJOA score); the difference of the spinal cord pulsation amplitude(SCPA) and the SCCEC forward movement rate (FMR) between the compressed areas(CAs) and the non-compressed areas (NCAs).ResultsA total of 38 patients were successfully enrolled (30 males and 8 females), and the mean age was 57.05 ± 10.29 (27–75) years. The cross-sectional area of the SC was negatively correlated with age (r = − 0.441, p = 0.006). The preJOA score was significantly lower in the heterogeneous group than in the homogeneous group (P < 0.05, p = 0.005). The hyperechoic area (HEA) was negatively while the SCCEC FMR was positively correlated with the preJOA score (r = − 0.334, p = 0.020; r = 0.286, p = 0.041). The SCCEC FMR and SCPA in CAs were significantly greater than those in NCAs (p < 0.05, p = 0.007; P < 0.001, P = 0.000).ConclusionThe cross-sectional area of the SC decreases with age in adults. More changes in intramedullary echogenicity and less moving forward of the SCCEC often indicate poor SC status, and the SCCEC FMR and SCPA are more pronounced in CAs.

Could TREM-1 be a novel marker in the diagnosis of fibromyalgia?: A cross-sectional study.

Triggering receptors expressed on myeloid cells-1 (TREM-1) are transmembrane molecules expressed in cells of the immune system. Activation of TREM-1 leads to the release of pro-inflammatory mediators, which act as amplifiers of inflammation and thereby contribute to the pathogenesis of various diseases, whether inflammatory or not. This study explored the role of TREM-1 in the etiopathogenic context of fibromyalgia syndrome (FMS) and its association with disease activity. This randomized controlled and observational study included 45 patients diagnosed with FMS according to the 2016 American College of Rheumatology criteria. Serum TREM-1 levels were assessed using ELISA, and disease activity was measured using various scales such as the fibromyalgia impact questionnaire (FIQ). Patients were divided into 2 groups according to disease severity based on the FIQ score. Compared to a control group of 46 healthy individuals, patients with FMS exhibited significantly elevated concentrations of TREM-1 (mean ± SD = 216.97 pg/mL ± 16.04), P < .05. The FIQ, Pittsburgh sleep quality index, hospital anxiety and depression scale, fatigue severity scale, and visual analog scale, which confirm symptoms such as pain, disease severity, sleep disturbance, depression, anxiety, and fatigue seen in FMS was significantly correlated with TREM-1 level (P < .001). The optimal threshold value for TREM-1 to disease activity was determined to be 182.250, showing (area under the curve) (CI (95%)): [0.940] (0.887-0.993), a sensitivity of 97% and a specificity of 89% according to the receiver operating characteristic analysis. The positive correlation of TREM-1 with various symptom severity scales and hematological inflammatory indices may be a suitable biomarker for the diagnosis of FMS and a potential therapeutic target.

Gut microbiota-melatonin signaling axis in acute pancreatitis: Revealing the impact of gut health on pancreatic inflammation and disease severity in a case-control study.

Acute pancreatitis (AP), a severe inflammatory condition affecting the pancreas requires investigation into its predictors. Melatonin, a compound with anti-inflammatory and antioxidant properties, has shown promise in managing AP. Additionally, the gut microbiota, a community of microorganisms residing in the intestines has been linked to AP development. This study aims to explore the correlation between melatonin and gut microbiota in predicting AP severity. This study involved 199 participants, with 99 diagnosed with AP and 100 serving as healthy controls. The AP patients were categorized into 2 groups based on the severity of their condition: mild AP (MAP) and severe AP (SAP). Serum melatonin levels were measured on Days 1, 3, and 5 of hospitalization, and gut microbiota composition was examined via 16S rRNA gene sequencing. Other parameters were evaluated, such as the Acute Physiology and Chronic Health Evaluation (APACHE) score, Ranson, and Acute Gastrointestinal Injury (AGI) scores. Melatonin levels were significantly lower in subjects with severe AP compared those with mild AP (18.2 ng/mL vs 32.2 ng/mL, P = .001), and melatonin levels decreased significantly in patients with AP on Days 3 and 5. The study also revealed that individuals with AP exhibited a significantly altered gut microbiota composition compared to control individuals, with a lower Shannon index and higher Simpson index. The AUCs for Simpson index and F/B ratio were significantly higher than those for other biomarkers, indicating that these gut microbiota markers may also be useful for AP prediction. The study proposes that there is a relationship between melatonin levels and the dynamics of gut microbiota profiles in relation to the severity of AP. As a result, the severity of the disease can be assessed by assessing the levels of serum melatonin and gut microbiota profiles.

Ruxolitinib Cream in Adolescents/Adults with Atopic Dermatitis Meeting Severity Thresholds for Systemic Therapy: Exploratory Analysis of Pooled Results from Two Phase3 Studies.

Standard therapy for patients with mild to moderate atopic dermatitis (AD) typically includes topical therapies; however, patients with more extensive AD and/or AD refractory to topical therapy may benefit from systemic treatment. Ruxolitinib cream monotherapy has demonstrated superior antipruritic and anti-inflammatory effects versus vehicle in patients with mild to moderate AD, and long-term disease control with as-needed use. Here, efficacy/safety of 1.5% ruxolitinib cream through 52weeks was assessed in a subset of patients with moderate and/or more extensive disease. This post hoc analysis of TRuE-AD1/TRuE-AD2 included patients who, at baseline, had Investigator's Global Assessment (IGA) score of 3, Eczema Area and Severity Index (EASI) ≥ 16, and affected body surface area (BSA) ≥ 10% (higher severity of disease threshold subgroup). Disease control and safety were assessed. Of 1249 patients in the overall population, 78 (6.2%) met all higher severity of disease threshold criteria (continuous-use vehicle-controlled period: 1.5% ruxolitinib cream, n = 32; vehicle, n = 13); 28 and 4 of these patients, respectively, continued as-needed 1.5% ruxolitinib cream during the long-term safety (LTS) period. At week8 (continuous-use), IGA-treatment success (IGA0/1, with ≥ 2-grade improvement from baseline) was achieved by 19/32 (59.4%) patients applying 1.5% ruxolitinib cream versus no patients applying vehicle. In the LTS period, those achieving clear/almost clear skin increased from 19/28 patients (67.9%; continuous-use: week8) to 18/23 patients (78.3%; as-needed use: week52) in patients applying ruxolitinib cream from day1. Ruxolitinib cream was well tolerated, with few application site reactions, regardless of disease severity threshold. Efficacy and safety results were similar to the overall study population. Patients with AD who meet standard disease severity eligibility criteria for systemic therapy may achieve IGA-treatment success with clear/almost clear skin with continuous-use ruxolitinib cream, and maintain long term-disease control with as-needed ruxolitinib cream monotherapy.

Serum Erythropoietin and Ischemic-Modified Albumin Levels in Adolescents with Obsessive–Compulsive Disorder

Erythropoietin (EPO) has neuroprotective effects by increasing oxidative stress resistance and stabilizing redox balance. Ischemic-modified albumin (IMA) is a product of protein oxidation, and recent evidence suggests that IMA can be used as an indicator of oxidative damage. This study aimed to investigate serum EPO and IMA levels in obsessive–compulsive disorder (OCD) patients and to investigate the relationship between EPO and IMA levels and clinical variables such as disease duration and disease severity. A total of 68 adolescents (11–18 years old), including 35 OCD patients (18 males/17 females) and 33 healthy controls (14 males/19 females) without comorbid disorders matched for age, gender, and BMI, were included in the study. The enzyme-amplified chemiluminescence technique determined serum EPO levels, and serum IMA levels were determined by the spectrophotometric method. Serum EPO levels were lower in OCD patients compared to healthy controls (p = 0.002; Z = − 3.123), and serum IMA levels (ABSU) were significantly higher in the OCD group (p = 0.005). A significant positive correlation was found between IMA levels and the duration of OCD symptoms (p = 0.015, r = 0.409). The study’s findings contribute to the growing body of evidence implicating inflammatory and oxidative processes in the pathogenesis of OCD. The potential of EPO and IMA levels as diagnostic biomarkers for OCD aligns with the ongoing efforts to identify reliable biological markers for the disorder. The positive correlation of IMA levels with the duration of OCD shows the importance of early detection of oxidative damage.

Antipsychotic-induced prolactin elevation in premenopausal women with schizophrenia: associations with estrogen, disease severity and cognition.

Antipsychotic-induced prolactin elevation may impede protective effects of estrogens in women with schizophrenia-spectrum disorders (SSD). Our study sought to confirm whether the use of prolactin-raising antipsychotics is associated with lower estrogen levels, and to investigate how estrogen and prolactin levels relate to symptom severity and cognition in premenopausal women with SSD. This cross-sectional study included 79 premenopausal women, divided in three groups of women with SSD treated with prolactin-sparing antipsychotics (n = 21) or prolactin-raising antipsychotics (n = 27), and age-matched women without SSD (n = 31). Circulating 17β-estradiol was compared among groups. In patients, we assessed the relationship between prolactin and 17β-estradiol, and the relationships of these hormones to symptom severity and cognition, using correlation analyses and backward regression models. In women receiving prolactin-raising antipsychotics, 17β-estradiol levels were lower as compared to both other groups (H(2) = 8.34; p = 0.015), and prolactin was inversely correlated with 17β-estradiol (r=-0.42, p = 0.030). In the prolactin-raising group, 17β-estradiol correlated positively with verbal fluency (r = 0.52, p = 0.009), and 17β-estradiol and prolactin together explained 29% of the variation in processing speed (β17β-estradiol = 0.24, βprolactin=-0.45, F(2,25) = 5.98, p = 0.008). In the prolactin-sparing group, 17β-estradiol correlated negatively with depression/anxiety (r=-0.57, p = 0.014), and together with prolactin explained 26% of the variation in total symptoms (β17β-estradiol=-0.41, βprolactin = 0.32, F(2,18) = 4.44, p = 0.027). In women with SSD, antipsychotic-induced prolactin elevation was related to lower estrogen levels. Further, estrogens negatively correlated with symptom severity and positively with cognition, whereas prolactin levels correlated negatively with cognition. Our findings stress the clinical importance of maintaining healthy levels of prolactin and estrogens in women with SSD.

Targeting a microbiota Wolbachian aminoacyl-tRNA synthetase to block its pathogenic host.

The interplay between humans and their microbiome is crucial for various physiological processes, including nutrient absorption, immune defense, and maintaining homeostasis. Microbiome alterations can directly contribute to diseases or heighten their likelihood. This relationship extends beyond humans; microbiota play vital roles in other organisms, including eukaryotic pathogens causing severe diseases. Notably, Wolbachia, a bacterial microbiota, is essential for parasitic worms responsible for lymphatic filariasis and onchocerciasis, devastating human illnesses. Given the lack of rapid cures for these infections and the limitations of current treatments, new drugs are imperative. Here, we disrupt Wolbachia's symbiosis with pathogens using boron-based compounds targeting an unprecedented Wolbachia enzyme, leucyl-tRNA synthetase (LeuRS), effectively inhibiting its growth. Through a compound demonstrating anti-Wolbachia efficacy in infected cells, we use biophysical experiments and x-ray crystallography to elucidate the mechanism behind Wolbachia LeuRS inhibition. We reveal that these compounds form adenosine-based adducts inhibiting protein synthesis. Overall, our study underscores the potential of disrupting key microbiota to control infections.

Passive Immunization Strategies to Prevent Severe Respiratory Syncytial Virus Infection Among Newborns and Young Infants.

Newborns and young infants are at risk for severe respiratory syncytial virus (RSV) lower respiratory tract infection. Passive immunity is the mainstay of infection prevention in this cohort. Transplacental transfer of maternal antibodies provides the newborn with immediate protection from life-threatening infections, however, is dependent upon gestational age, birth weight, mother's age, recent maternal vaccination, maternal nutritional status, maternal immunocompetence and medical conditions, and placental integrity. Efficient transplacental transfer of RSV-neutralizing antibodies have led to the development and approval of maternal RSV immunization for the protection of the newborn. Additionally, administration of RSV-specific antibodies to infants leads to high serum titers of RSV-neutralizing antibodies and further protection from severe disease.

Antibody levels against respiratory syncytial virus fusion protein conformations and lack of association with life-threatening infection in previously healthy infants

BackgroundHumoral immune response against the pre-fusion (pre-F) conformation of respiratory syncytial virus (RSV) F protein has been proposed to play a protective role against infection. An RSV pre-F maternal vaccine has been recently approved in several countries to protect young infants against RSV. We aimed to assess serum IgG titers against the pre-F and post-F conformations of RSV F protein and their association with life-threatening RSV disease (LTD) in previously healthy infants. MethodsA prospective cohort study including hospitalized infants <12 months with a first RSV infection was conducted during 2017–2019. Patients with LTD required intensive care and mechanical respiratory assistance. RSV pre-F exclusive and post-F antibody responses were determined by post-F competition and non-competition immunoassays, respectively, and neutralizing activity was measured by plaque reduction neutralization test. ResultsFifty-eight patients were included; the median age was 3.5 months and 41 % were females. Fifteen patients developed LTD. RSV F-specific antibody titers positively correlated with neutralizing antibody titers in acute and convalescent phases but, importantly, they did not associate with LTD. Acute RSV pre-F exclusive and post-F IgG titers negatively correlated with patient age (P = 0.0007 and P < 0.0001), while a positive correlation was observed between the fold changes in RSV F-specific antibody titers between convalescent and acute phase and patient age (P = 0.0014 and P < 0.0001). Infants ≤2 months exhibited significantly lower fold-changes in RSV F-specific and neutralizing antibody titers between convalescence and acute phase than older infants. Additionally, acute RSV antibody titers showed no correlation with nasal RSV load and, furthermore, nasal viral load was not associated with the development of LTD. ConclusionsThis study highlights that protection against life-threatening RSV disease is not necessarily antibody-dependent. Further characterization of the immune response against RSV and its role in protection against severe disease is important for the development of the safest possible preventive strategies.

A Retrospective Case Series Analysis of Pregnancy and COVID-19 Based on a Global Postmarketing COVID-19 Surveillance Program

PurposeTo document and characterize COVID-19 cases involving pregnancy in the context of exposure to pharmaceutical products. MethodsThis retrospective case series analysis leveraged the Pfizer safety database containing worldwide adverse event data related to use of Pfizer products between October 1, 2019 and November 3, 2022. Selected Medical Dictionary for Drug Regulatory Activities (Version 25.0) Preferred Terms and subsequent clinical review were used to identify COVID-19 cases involving female patients who received Pfizer products during pregnancy and infants with intrauterine exposure to Pfizer products. FindingsAs of November 3, 2022, 504 pregnancy cases (426 maternal; 78 infants) were identified. Most maternal cases reported COVID-19 during the third trimester, and (when known) 52% of cases involved presentation or progression of severe COVID-19 with associated complications requiring hospitalization, and often intensive management (eg, mechanical ventilation, oxygen support) and emergent delivery. Twenty-three maternal cases were fatal; patients developed severe COVID-19 disease involving multisystem deterioration (eg, cardiopulmonary injury/decompensation, coagulopathies, septic/hemorrhagic shock) and frequently required risk-benefit decisions regarding maintaining/prolonging pregnancies to improve fetal viability while attempting to improve or stabilize maternal conditions or electing to either terminate pregnancies or induce emergent deliveries. Approximately 40% of maternal cases reported medical history involving at least one underlying condition (eg, diabetes, respiratory disorders, renal/hepatic disease, cardiac disease, obesity, autoimmune conditions) considered potentially associated with susceptibility to infection/adverse outcome of infection, or twin/triplet pregnancy, which may further complicate COVID-19 disease. Most cases with known fetal outcomes reported normal newborns including preterm/low birth weight infants, which occurred in many cases involving emergent preterm delivery due to deteriorating maternal conditions. The remaining smaller proportion of cases involved abnormal newborn/perinatal/postperinatal complications (eg, premature births, respiratory distress, alveolar damage, meconium aspiration with hypoxic-ischemic encephalopathy), intrauterine/neonatal death (due to multiple concurrent complications such as neonatal sepsis, hypoxemia/acute respiratory distress, potential cardiac damage, mucormycosis) and congenital anomaly (eg, intrauterine growth restriction in association with contracting COVID-19). Among infants tested within our dataset, 28 cases involved reference to infants who tested positive for COVID-19 infection at birth or shortly thereafter, with vertical transmission suspected only in 2 infants. ImplicationThis large retrospective case series provides additional perspectives regarding potential impact of COVID-19 on pregnancy outcomes, and its characterization of this case volume may contribute to the current information landscape related to COVID-19 in pregnancy. Further studies may be warranted to confirm the generalizability of our findings to the general pregnant patient population infected with COVID-19.

Clinical outcomes of carbapenem-resistant gram-negative bacterial bloodstream infection in patients with end-stage renal disease in intensive care units: a multicenter retrospective observational study.

Carbapenem-resistant gram-negative bacteria (CRGNB) present a considerable global threat due to their challenging treatment and increased mortality rates, with bloodstream infection (BSI) having the highest mortality rate. Patients with end-stage renal disease (ESRD) undergoing renal replacement therapy (RRT) face an increased risk of BSI. Limited data are available regarding the prognosis and treatment outcomes of CRGNB-BSI in patients with ESRD in intensive care units (ICUs). This multi-center retrospective observational study included a total of 149 ICU patients with ESRD and CRGNB-BSI in Taiwan from January 2015 to December 2019. Clinical and microbiological outcomes were assessed, and multivariable regression analysis was used to evaluate the independent risk factors for day-28 mortality and the impact of antimicrobial therapy regimen on treatment outcomes. Among the 149 patients, a total of 127 patients (85.2%) acquired BSI in the ICU, with catheter-related infections (47.7%) and pneumonia (32.2%) being the most common etiologies. Acinetobacter baumannii (49.0%) and Klebsiella pneumoniae (31.5%) were the most frequently isolated pathogens. The day-28 mortality rate from BSI onset was 52.3%, and in-hospital mortality was 73.2%, with survivors experiencing prolonged hospital stays. A higher Sequential Organ Failure Assessment (SOFA) score (adjusted hazards ratio [aHR], 1.25; 95% confidence interval [CI] 1.17-1.35) and shock status (aHR, 2.12; 95% CI 1.14-3.94) independently predicted day-28 mortality. Colistin-based therapy reduced day-28 mortality in patients with shock, a SOFA score of ≥ 13, and Acinetobacter baumannii-related BSI. CRGNB-BSI led to high mortality in critically ill patients with ESRD. Day-28 mortality was independently predicted by a higher SOFA score and shock status. In patients with higher disease severity and Acinetobacter baumannii-related BSI, colistin-based therapy improved treatment outcomes.

T87 - Long-Term Relationship Between Opioid Use and Change in HIV Disease Severity: A Prospective Cohort Study

T87 - Long-Term Relationship Between Opioid Use and Change in HIV Disease Severity: A Prospective Cohort Study

Correlation Between Severity of Schizophrenia with Certain Trace Elements and TNF-α Gene Expression and Its Circulatory Level in the Population of Western India.

This cross-sectional study aimed to assess serum trace element (TE) concentrations, TNF-α gene expression, protein levels in schizophrenia (SZ) patients, and their correlation with disease severity measured by Positive and Negative Syndrome Scale (PANSS) scores. Forty SZ cases and 40 healthy controls aged 18-60 were recruited. Forty (n = 40) cases who meet ICD-10 criteria for SZ and 40 (n = 40) healthy individuals (controls) between 18 and 60years of age were recruited in the study. Sandwich enzyme-linked immunosorbent assay (ELISA) and RT-qPCR (quantitative real-time PCR) were used to estimate pro-inflammatory cytokine TNF-α protein and gene expression. Inductively coupled plasma-optical emission spectroscopy (ICP-OES) and graphite furnace atomic absorption spectroscopy (GFAAS) were used to assess serum levels of trace elements (TEs): Fe, Zn, Cu, Mg, and Se. Compared to healthy controls, cases had significantly higher levels of TNF-α protein, as well as Fe, Cu, and Se (p < 0.05). Cu correlated positively with TNF-α protein level (rho = 0.234; p = 0.048) and gene expression (rho = 0.333; p = 0.041) and with PANSS negative (rho = 0.531), general (rho = 0.643), and total (rho = 0.541) scores. Additionally, Zn negatively correlated with serum Mg (rho = - 0.426, p < 0.01) and positively with serum Se (rho = 0.343, p < 0.05). In conclusion, elevated Cu levels could potentially contribute to the development of SZ. Elevated Cu levels in cases and their correlation with the TNF-α gene and protein and PANSS score indicate Cu's potential role in exacerbating SZ severity through inflammatory cytokines. This suggests the involvement of metals and cytokines in the pathophysiology of SZ.

People with osteoarthritis have a higher component of neuropathic pain as compared to those with rheumatoid arthritis: A cross-sectional study.

Neuropathic pain may be present in a proportion of patients with osteoarthritis (OA) and rheumatoid arthritis (RA). Its presence may lead to the requirement of altered management approaches in these conditions. This study investigated the prevalence of neuropathic pain in OA as compared to that in RA. Patients with OA and RA were included cross-sectionally if they had no other known neuropathic disorder. The PainDETECT questionnaire was used to assess neuropathic pain. WOMAC and CDAI scores were used to assess disease severity in OA and RA respectively. 69 patients with OA with a mean WOMAC score of 53.30 ± 16.39 and 98 patients with RA with a mean CDAI of 25.48 ± 16.99 were compared. The median PainDETECT score for OA was 13 (0-30) and RA was 5 (0-37) [p<0.001]. 15 patients with OA and six patients with RA were highly likely to have neuropathic pain, while 15 patients with OA and 30 patients with RA were classified as possibly having neuropathic pain. Thus, the proportion of patients free from neuropathic pain was higher in the RA group (63.3%) than in the OA group (39.1%) [p = 0.003]. Both the prevalence and the severity of neuropathic pain were significantly higher in OA than in RA. These findings suggest that neuropathic pain is an important factor in OA, as in RA, and must be considered in management as well as in future research in both these conditions.

How to integrate surgery and targeted therapy with biologics for the treatment of hidradenitis suppurativa: Delphi consensus statements from an Italian expert panel.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent and painful nodules and abscesses in intertriginous skin areas, which can progress to sinus tract formation, tissue destruction, and scarring. HS is highly debilitating and severely impairs the psychological well-being and quality of life of patients. The therapeutic approach to HS is based on medical therapy and surgery. First-line medical therapy includes topical antibiotics, systemic antibiotics, and biologics. Main surgical procedures include deroofing, local excision, and wide local excision. Despite the availability of multiple therapeutic options, the rates of disease recurrence and progression continue to be high. In recent years, the possibility of combining biologic therapy and surgery has raised considerable interest. In a clinical trial, the perioperative use of adalimumab has been associated with greater response rates and improved inflammatory load and pain, with no increased risk of postoperative infectious complications. However, several practical aspects of combined biologic therapy and surgery are poorly defined. In June 2022, nine Italian HS experts convened to address issues related to the integration of biologic therapy and surgery in clinical practice. To this purpose, the experts identified ten areas of interest based on published evidence and personal experience: 1) patient profiling (diagnostic criteria, disease severity classification, assessment of response to treatment, patient-reported outcomes, comorbidities); 2) tailoring surgery to HS characteristics; 3) wide local excision; 4) pre-surgery biologic treatment; 5) concomitant biologic and surgical treatments; 6) pre- and post-surgery management; 7) antibiotic systemic therapy; 8) biologic therapy after radical surgery; 9) management of adverse events to biologics; 10) management of postoperative infectious complications. Consensus between experts was reached using the Estimate-Talk-Estimate method (Delphi Method). The statements were subsequently presented to a panel of 27 HS experts from across Italy, and their agreement was assessed using the UCLA Appropriateness Method. This article presents and discusses the consensus statements.

A Review of Respiratory Syncytial Virus Epidemiology Among Children: Linking Effective Prevention to Vulnerable Populations.

Respiratory syncytial virus (RSV) is the greatest contributor to lower respiratory tract infections (LRTI) in children less than 5 years of age and the leading cause for infant hospitalizations in the United States (US). The burden of severe disease disproportionately impacts racial and ethnic minority groups, highlighting the need for interventions that promote health equity. Recent advancements in effective prophylactic agents have the potential to drastically alter the landscape of RSV disease among all young children. The effectiveness of prophylaxis, however, will rely on a clear understanding of RSV epidemiology. The purpose of this review is to discuss key aspects of RSV epidemiology while focusing on efforts to support equitable distribution of prophylactic agents to mitigate existing health disparities.

Hepatitis B infection and immunity in Migrant Children and Pregnant Persons in Europe: A Systematic Review and Meta-Analysis.

The WHO's global hepatitis strategy aims to achieve viral hepatitis elimination by 2030. Migrant children and pregnant persons represent an important target group for prevention strategies. However, evidence on the burden of chronic hepatitis B (CHB) infection, and the factors affecting incidence, is lacking. EMBASE, Global Health, Global Index Medicus, Web of Science and Medline were searched for articles in any language from 1/1/2012 to 8/6/2022. Studies reporting CHB prevalence, disease severity, complications and/or prevention strategies including vaccination, prevention of vertical transmission, and access to care/treatment in migrant children and pregnant migrants were included. Pooled estimates of CHB prevalence and Hepatitis B vaccination (HBV) coverage among migrant children were calculated using random effects meta-analysis. 42 studies were included, 27 relating to migrant children and 15 to pregnant migrants across 12 European countries, involving data from 64 773 migrants. Migrants had a higher incidence of CHB than host populations. Among children, the pooled prevalence of CHB was higher for unaccompanied minors (UAM) (5%, [95% CI: 3-7%]) compared to other child migrants including internationally adopted children (IAC) and refugees (1%, [95% CI: 1-2%]). Region of origin was identified as a risk factors for CHB, with children from Africa and pregnant migrants from Africa, Eastern Europe and China at highest risk. Pooled estimates of HBV vaccine coverage were lower among UAM (12%, [95% CI: 3-21%]) compared to other child migrants (50%, [95% CI: 37-63%]). A range of modifiable determinants of HBV prevalence in migrant children and pregnant persons were identified including sub-optimal screening, prevention, and continuum of care. There is a need to develop evidence-based approaches in hepatitis care for these groups, thereby contributing towards global viral hepatitis elimination goals.

Diffusion Tensor Imaging-Along the Perivascular-Space Index Is Associated with Disease Progression in Parkinson's Disease.

The glymphatic clearance pathway is a waste clearance system that allows for removal of soluble proteins such as amyloid β (Aβ) from the brain. Higher Aβ levels are associated with cognitive dysfunction in Parkinson's disease (PD). Diffusion tensor imaging-along the perivascular space (DTI-ALPS) is an imaging measure proposed to indirectly measure glymphatic function. Evaluate differences in DTI-ALPS-index between PD and healthy controls (HC) and characterize relationships between this proposed measure of glymphatic clearance, cognition, and disease severity in PD. PD (n = 32) and HC (n = 23) participants underwent brain imaging to assess DTI-ALPS. PD participants were classified as PD-normal cognition (PD-NC; n = 20) or PD-mild cognitive impairment (PD-MCI; n = 12) based on a Level II comprehensive cognitive assessment. A subgroup of PD participants (n = 21) returned for annual assessments for up to 4 years after baseline. Longitudinal outcomes included changes in performance on the comprehensive cognitive assessment and changes in the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS). PD participants had lower DTI-ALPS-index compared to HC. PD participants classified as PD-MCI had significantly lower DTI-ALPS-index compared to PD-NC. Lower DTI-ALPS-index at baseline was associated with longitudinal cognitive decline and worse longitudinal disease severity. Glymphatic clearance, as measured with DTI-ALPS, has potential to serve as a marker of longitudinal disease progression. Interventions targeting glymphatic function should be explored for potential to slow cognitive decline in PD. © 2024 International Parkinson and Movement Disorder Society.
