High-throughput proteomic platforms are crucial to identify novel Alzheimer's disease (AD) biomarkers and pathways. In this study, we evaluated the reproducibility and reliability of aptamer-based (SomaScan 7k) and antibody-based (Olink Explore 3k) proteomic platforms in cerebrospinal fluid (CSF) samples from the Ace Alzheimer Center Barcelona real-world cohort. Intra- and inter-platform reproducibility were evaluated through correlations between two independent SomaScan assays analyzing the same samples, and between SomaScan and Olink results.

Background: Prune belly syndrome (PBS) is a rare condition characterized by absence of abdominal musculature, cryptorchidism, and obstructive uropathy. The most common orthopaedic problem is scoliosis, yet no reports on growth-friendly surgical treatment of early-onset scoliosis (EOS) exist. Our purpose was to evaluate outcomes of distraction-based implants in children with PBS.

Swallowing, both nutritive and non-nutritive, is highly dysfunctional in children with Leigh Syndrome (LS) and contributes to the need for both gastrostomy and tracheostomy tube placement. Without these interventions aspiration of food, liquid, and mucus occur resulting in repeated bouts of respiratory infection. No study has investigated whether mouse models of LS, a neurometabolic disorder, exhibit dysfunctions in neuromuscular activity of swallow and breathing integration.

T cells are involved in protective immunity against numerous viral infections. Data regarding functional roles of human T cells in SARS-CoV-2 (SARS2) viral clearance in primary COVID-19 are limited. To address this knowledge gap, we assessed samples for associations between SARS2 upper respiratory tract viral RNA levels and early virus-specific adaptive immune responses for 95 unvaccinated clinical trial participants with acute primary COVID-19 aged 18-86 years old, approximately half of whom were considered at high risk for progression to severe COVID-19.

Objective: To describe the impact of the new intervention model implemented by Paraguay across five districts of the Central Region in the last quarter of 2023, consisting of an integrated health services-based strategy to recover coverage with the tracer vaccine (pentavalent until April 2023, hexavalent thereafter) in children under 1 year of age; and the measles, mumps, and rubella (MMR) vaccine for the 1-year-old population.

Methods: Descriptive, cross-sectional study with comparative analysis before (epidemiological weeks [EW] 1 and 34 of 2023) and after (EW35 and EW52 of 2023) the intervention. Three indicators were assessed: a) coverage with all three doses of pentavalent or hexavalent vaccine and first and second doses of MMR; b) productivity, represented by third doses of pentavalent or hexavalent vaccine administered; and c) dropout rates for the pentavalent or hexavalent and MMR vaccines.

Background: Depression affects 33% of women with type 2 diabetes (T2D) and leads to increased risks of premature mortality. Fluctuation and variation of depressive presentations can hinder clinical identification.

Purpose: We aimed to identify and examine subgroups characterized by distinct depressive symptom trajectories among women with T2D.

Article Synopsis
  • A study was conducted to investigate the X-chromosome's role in Alzheimer's Disease (AD), which had been overlooked in previous genome-wide association studies.
  • The research included 115,841 AD cases and 613,671 controls, considering different X-chromosome inactivation (XCI) states in females.
  • While no strong genetic risk factors for AD were found on the X-chromosome, seven significant loci were identified, suggesting areas for future research.

  • The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
  • A special data scouting method is utilized to pick out events with low combined momentum in jets.
  • This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.

We studied cervicovaginal β-/γ-human papillomavirus (HPV) and their relationship to cervical precancer in women with HIV (WWH); having previously reported strong positive associations of β-/γ-HPV with incident head and neck cancer in the general population. Cases (N=124) had cervical intraepithelial neoplasia (CIN)-3 or CIN-2. Controls (N=247) were individually matched 2:1 to cases.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Article Synopsis
  • Parkinson's disease (PD) is a long-term brain disorder affecting movement and can also lead to issues like sleep problems and breathing difficulties, which lower quality of life.
  • In a study using a 6-OHDA mouse model, researchers found that PD altered sleep-related breathing patterns, leading to fewer breaths and more apnea episodes during both types of sleep.
  • By stimulating specific cholinergic neurons in the LDTg region of the brain, they were able to restore normal breathing, indicating that targeting these neurons could be a potential treatment for respiratory issues in PD patients.

Background: Sarcopenic obesity is a condition where loss of muscle mass occurs alongside fat gain, and it is considered a risk factor for mortality. However, the use of various definitions for this condition has led to conflicting results.

Aim: To investigate whether the coexistence of low muscle mass and abdominal obesity, defined using two simple measures employed in clinical practice, is a risk factor for mortality in individuals aged 50 or older.

  • The study investigates racial disparities in SARS-CoV-2 vaccination rates among people with HIV (PWH) and those at risk for HIV, focusing on the roles of medical mistrust and vaccine hesitancy.
  • It utilizes data from a diverse cohort and employs various statistical analyses to explore the impact of social demographics on vaccination attitudes and behaviors.
  • Results show that Black participants are significantly more likely to be unvaccinated compared to white participants, primarily due to medical mistrust and vaccine hesitancy, highlighting the urgent need for improving trust in healthcare to address these disparities.

The control of the respiratory rhythm and airway motor activity is essential for life. Accumulating evidence indicates that the postinspiratory complex (PiCo) is crucial for generating behaviors that occur during the postinspiratory phase, including expiratory laryngeal activity and swallowing. Located in the ventromedial medulla, PiCo is defined by neurons co-expressing two neurotransmitter markers (ChAT and Vglut2/Slc17a6).

  • Migrants and refugees often struggle with mental health issues but have limited access to proper services, prompting this study to explore ways to deliver psychological support in Colombia using a group intervention called gPM+.
  • The study compared two training methods for nonspecialists delivering gPM+: one receiving support from a psychologist and the other from a trained nonspecialist, enrolling 128 distressed adult women in the process.
  • Results showed higher attendance in the psychologist-supported group, but the trained nonspecialist group was more cost-effective and maintained fidelity in delivering the program, highlighting the potential for using community-based methods for mental health interventions.
