The Ponseti Method vs. Surgical Treatment for Idiopathic Clubfoot: A Prospective Long-Term Follow-Up.

Idiopathic clubfoot is a common skeletal deformity in newborns that can cause functional limitations, pain, and reduced quality of life. The Ponseti method has become the gold standard for clubfoot treatment, replacing previous extensive surgical approaches. However, there is a lack of prospective long-term data comparing surgical and Ponseti treatments.

Heterologous immunization strategy developed broadly reactive human monoclonal antibodies against the BK virus.

BK polyomavirus (BKV) causes polyomavirus-associated nephropathy (PyVAN) and polyomavirus-associated hemorrhagic cystitis (PyVHC) following kidney transplantation and allogeneic hematopoietic stem cell transplantation (HST). BKV strains fall into four distinct genotypes (BKV-I, -II, -III, and -IV) with more than 80% of individuals are seropositive against BKV-I genotype, while the seroprevalence of the other four genotypes is lower. PyVAN and PyVHC occurs in immunosuppressed (e.

Predictors of treatment duration in conservative management of developmental dysplasia of hip -a retrospective cohort study.

Developmental dysplasia of the hip is a prevalent condition in newborns. However, predicting the duration of conservative treatment remains challenging. This study aimed to determine the duration of treatment more precisely by analyzing associated factors.

A retrospective, multicentric, nationwide analysis of the impact of splenectomy on survival of pancreatic cancer patients.

Objective: Splenectomy is regularly performed in total and distal pancreatectomy due to technical reasons, lymph node dissection and radicality of the operation. However, the spleen serves as an important organ for competent immune function, and its removal is associated with an increased incidence of cancer and a worse outcome in some cancer entities (Haematologica 99:392-398, 2014; Dis Colon Rectum 51:213-217, 2008; Dis Esophagus 21:334-339, 2008). The impact of splenectomy in pancreatic cancer is not fully resolved (J Am Coll Surg 188:516-521, 1999; J Surg Oncol 119:784-793, 2019).

Line-dropped gelatin multi-element calibration standards in LA-ICP-MS: a statistically verifying comparison with cryosectioned homogenized lung and liver as matrix-matched calibration standards and as corresponding reference materials.

Calibrations in LA-ICP-MS are typically very time-consuming and complex, as they need to be matched to the samples being measured and sectioned on a microtome. Alternatively, gelatin can be in droplet form or as a section, which is a more recent development. In this study, we report on investigations where hot multi-element gelatin solutions are placed in a linear fashion on microscopic slides to conduct comparative statistical observations between doped tissue homogenates from the liver and lung.

Cutaneous infection in an immunocompromised domestic cat caused by Setosphaeria turcica (Luttr.) Leonard & Suggs.

This is the first report of a cutaneous infection in an immunocompromised domestic cat caused by Setosphaeria turcica. The investigation encompasses an assessment of its virulence factors and susceptibility to antifungal drugs. The isolated strain originated from a domestic cat displaying cutaneous lesions that tested positive for feline leukemia virus (FeLV) infection.

Validation of the Demand Control Support Questionnaire for European Portuguese.

Background: The Demand Control Support model is useful for studying work-related stress. The combination of high demand and a low level of control generates "job strain" ("job iso-strain" if poor support is added), with implications for the worker's health and well-being. The aims of this study were to adapt, examine the factor structure of, and determine the reliability of, the Demand Control Support Questionnaire (DCSQ) short version for European Portuguese (DCSQ-PT).

Near-Infinite-Chain Polymers with Ge=Ge Double Bonds.

Despite considerable interest in heteroatom-containing conjugated polymers, there are only few examples with heavier p-block elements in the conjugation path. The recently reported heavier acyclic diene metathesis (HADMET) allowed for the synthesis of a polymer containing Ge=Ge double bonds-albeit insoluble and with limited degree of polymerization. By incorporation of long alkyl chains, we now obtained soluble representatives, which exhibit degrees of polymerization near infinity according to diffusion-ordered NMR spectroscopy (DOSY) and dynamic light scattering (DLS).

Metabolic activation of WHO-congeners PCB28, 52, and 101 by human CYP2A6: evidence from in vitro and in vivo experiments.

Despite extensive research on the metabolism of polychlorinated biphenyls (PCBs), knowledge gaps persist regarding their isoform-specific biotransformation pathways. This study aimed to elucidate the role of different cytochrome P450 enzymes in PCB metabolism, focusing on WHO-congeners 2,4,4'-trichlorobiphenyl (PCB28), 2,2',5,5'-tetrachlorobiphenyl (PCB52), and 2,2',4,5,5'-pentachlorobiphenyl (PCB101). Utilizing engineered HEK293 cell lines, we investigated the in vitro metabolism of these PCBs by CYP1A2, CYP2C8, CYP2C9, CYP3A4, CYP2A6, and CYP2E1, revealing robust production of hydroxylated metabolites.

Pain-induced effects on the pupillary light response under high and low illumination conditions.

Objective: The present study investigated the impact of two different light intensities on the pain-modulated pupillary light response (PLR). Additionally, it aimed to demonstrate parasympathetic and sympathetic influences on PLR parameters in response to pain, as predicted by functional models.

Method: A total of 24 participants were included in a randomized, repeated-measures design.

Stabilization of Apolar Nanoparticle Dispersions by Molecular Additives.

We study the effect of additives on the colloidal stability of alkanethiol-coated gold nanoparticles. Cyclic amines and sulfides of different sizes were added to dispersions in decane at additive concentrations below 128 mM. Small-angle X-ray scattering (SAXS) indicated that tetrahydrothiophene reduced the agglomeration temperature, , by up to 29 °C, a considerable increase in colloidal stability.

Mechanically Robust, Inkjet-Printable Polymer Nanocomposites with Hybrid Gold Nanoparticles and Metal-like Conductivity.

Hybrid core-shell nanoparticles with metal cores and conductive polymer shells yield materials that are sinter-free and highly conductive but mechanically weak. Conventional composites of such nanoparticles are electrically insulating. Here, we introduce microscale phase-separated nanocomposites of hybrid gold-PEDOT:PPS particles in insulating poly(vinyl alcohol) (PVA).

A broadly neutralizing human monoclonal antibody generated from transgenic mice immunized with HCMV particles limits virus infection and proliferation.

Unlabelled: Human cytomegalovirus (HCMV) is a β-herpesvirus that poses severe disease risk for immunocompromised patients who experience primary infection or reactivation. Development and optimization of safe and effective anti-HCMV therapeutics is of urgent necessity for the prevention and treatment of HCMV-associated diseases in diverse populations. The use of neutralizing monoclonal antibodies (mAbs) to limit HCMV infection poses a promising therapeutic strategy, as anti-HCMV mAbs largely inhibit infection by targeting virion glycoprotein complexes.

Nanocrystal Assemblies: Current Advances and Open Problems.

We explore the potential of nanocrystals (a term used equivalently to nanoparticles) as building blocks for nanomaterials, and the current advances and open challenges for fundamental science developments and applications. Nanocrystal assemblies are inherently multiscale, and the generation of revolutionary material properties requires a precise understanding of the relationship between structure and function, the former being determined by classical effects and the latter often by quantum effects. With an emphasis on theory and computation, we discuss challenges that hamper current assembly strategies and to what extent nanocrystal assemblies represent thermodynamic equilibrium or kinetically trapped metastable states.

Genome-Wide Methylation Analysis in Two Wild-Type Non-Small Cell Lung Cancer Subgroups with Negative and High PD-L1 Expression.

We conducted a pilot study to analyze the differential methylation status of 20 primary acinar adenocarcinomas of the lungs. These adenocarcinomas had to be wild type in mutation analysis and had either high (TPS > 50%; = 10) or negative (TPS < 1%; = 10) PD-L1 status to be integrated into our study. To examine the methylation of 866,895 specific sites, we utilized the Illumina Infinium EPIC bead chip array.

Soft Synthetic Cells with Mobile Membrane Ligands for Ex Vivo Expansion of Therapy-Relevant T Cell Phenotypes.

The expansion of T cells ex vivo is crucial for effective immunotherapy but currently limited by a lack of expansion approaches that closely mimic in vivo T cell activation. Taking inspiration from bottom-up synthetic biology, a new synthetic cell technology is introduced based on dispersed liquid-liquid phase-separated droplet-supported lipid bilayers (dsLBs) with tunable biochemical and biophysical characteristics, as artificial antigen presenting cells (aAPCs) for ex vivo T cell expansion. These findings obtained with the dsLB technology reveal three key insights: first, introducing laterally mobile stimulatory ligands on soft aAPCs promotes expansion of IL-4/IL-10 secreting regulatory CD8 T cells, with a PD-1 negative phenotype, less prone to immune suppression.

Pituitary Apoplexy in Macroadenoma After Minor Surgery: An Unusual Case and Literature Review.

Pituitary apoplexy is a rare and severe complication of pituitary adenoma that may present with new-onset headache, ocular palsy, visual disturbances, life-threatening electrolyte imbalance, and endocrinological disturbances due to pituitary hemorrhage and/or infarction. We report the case of a 58-year-old previously healthy patient who developed isolated mild oculomotor nerve palsy of the left eye following osteosynthesis of a traumatic right distal radius fracture. Initial cerebral magnetic resonance imaging showed a pituitary macroadenoma without characteristic signs of pituitary infarction or hemorrhage.

Evaluation and Comparison of Relaxation-Related Workplace Interventions Among Office Workers at an Insurance Institution: An Intervention Study.

Relaxation-related workplace interventions can be counterstrategies for stress due to office work and should be evaluated for success after implementation. This study reports on the evaluation and comparison of 3 relaxation techniques introduced as an intervention for health promotion. A Germany-wide multicenter evaluation of a 3-month relaxation intervention (30 min, once a week) including autogenic training, progressive muscle relaxation (PMR) or Tai Chi was conducted at 14 locations as an intervention study.

Definition of the Post-COVID syndrome using a symptom-based Post-COVID score in a prospective, multi-center, cross-sectoral cohort of the German National Pandemic Cohort Network (NAPKON).

Purpose: The objective examination of the Post-COVID syndrome (PCS) remains difficult due to heterogeneous definitions and clinical phenotypes. The aim of the study was to verify the functionality and correlates of a recently developed PCS score.

Methods: The PCS score was applied to the prospective, multi-center cross-sectoral cohort (in- and outpatients with SARS-CoV-2 infection) of the "National Pandemic Cohort Network (NAPKON, Germany)".

Value of follow-up diagnostic radioiodine scans in differentiated thyroid cancer.

Background: The most important part of the follow-up of differentiated thyroid carcinoma (DTC) is the measurement of serum thyroglobulin (Tg). An increase of Tg levels indicates likely tumor recurrence. According to the guidelines of the European Society of Medical Oncology (ESMO), the follow-up should consist of serum Tg assays and a neck ultrasound, while the American Thyroid Association (ATA) recommends serum Tg assays, neck ultrasounds, and a diagnostic radioiodine whole-body scan (WBS) if non-stimulated Tg is greater than 10 ng/mL or if Tg is rising.

Adjuvant Gemcitabine Versus Neoadjuvant/Adjuvant FOLFIRINOX in Resectable Pancreatic Cancer: The Randomized Multicenter Phase II NEPAFOX Trial.

Background: Although addition of adjuvant chemotherapy is the current standard, the prognosis of pancreatic cancers still remains poor. The NEPAFOX trial evaluated perioperative treatment with FOLFIRINOX in resectable pancreatic cancer.

Patients And Methods: This multicenter phase II trial randomized patients with resectable or borderline resectable pancreatic cancer without metastases into arm (A,) upfront surgery plus adjuvant gemcitabine, or arm (B,) perioperative FOLFIRINOX.
