Mycosis fugnoides (MF) is an indolent cutaneous T-cell lymphoma (CTLC) and is the most common of all cutaneous lymphomas. An increased risk for developing a second primary malignancy in patients with CTCL has been described in several studies, with a range from 1.04 to 2.4 (1-4). Caucasian males are at higher risk for MF development. MF is often diagnosed at ages between 55 and 67 years, and second malignancy usually occurs 5 or 6 years after the diagnosis of MF was established (5). The most common second primary malignancies include non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), lung carcinoma, bladder carcinoma, and melanoma...

The observation of multiple conformations of a functional loop (termed M20) in the Escherichia coli dihydrofolate reductase ( ec DHFR) enzyme triggered the proposition that large-scale motions of protein structural elements contribute to enzyme catalysis. The transition of the M20 loop from a closed conformation to an occluded conformation was thought to aid the rate-limiting release of the products. However, the influence of charged species in the solution environment on the observed M20 loop conformations, independent of charged ligands bound to the enzyme, had not been considered...

PURPOSE: To explore the relationship between preoperative J-sign grading and structural bone abnormalities in patients with recurrent patellar dislocation (RPD). METHODS: A retrospective study was conducted on RPD patients over 5 years. Patients were categorised based on J-sign grade into low (J- and J1+), moderate (J2+) and high groups (J3+). Trochlear dysplasia (TD) and osseous structures (femoral anteversion angle [FAA], knee torsion, tibial tuberosity-trochlear groove [TT-TG] distance, Caton-Deschamps index) were assessed and grouped according to risk factor thresholds...

Blood flow restriction (BFR) is a commonly used training modality that has been demonstrated to enhance muscle characteristics such as size and function. The purpose of this study was to determine if a 4-week walking program with or without BFR in healthy, active adults has an effect on body composition, anaerobic, and aerobic running performance. Thirty-three participants, randomized among three groups, completed the walking program, which included five sets of 2 min walking intervals with 1 min rest, with or without BFR, or 10 min walking with BFR...

BACKGROUND: One of the mechanisms regulating the biological activity of tumor necrosis factor (TNF) in cells is the co-expression of TNFR1/TNFR2 receptors. A model with a differential level of receptor expression is required to evaluate the contribution of these mechanisms. AIM: The development of a cellular model to compare the effects of TNF on cells depending on the presence of both receptors and TNFR2 alone. METHODS: TNFR1 absence modifications of ZR-75/1 and K-562 cell lines were obtained by TNFR1 knockout...

Total joint arthroplasty (TJA) is a surgical procedure, in which parts of damaged joints are removed and replaced with a prosthesis. The main indication of TJA is osteoarthritis, and the volume of TJA is rising annually along with the increase of aged population. Hip and knee are the most common joints, in which TJAs are performed. The TJA prosthesis is composed of metal, plastic, or ceramic device. Even though TJA is the most successful treatment for end-stage osteoarthritis, it is associated with various complications, and periprosthetic joint infection (PJI) is the most serious complication after TJA...

BACKGROUND: Quantitative measurement of minimal residual disease (MRD) is the "gold standard" for estimating the response to therapy in childhood B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Nevertheless, the speed of the MRD response differs for different cytogenetic subgroups. Here we present results of MRD measurement in children with BCP-ALL, in terms of genetic subgroups with relation to clinically defined risk groups. METHODS: A total of 485 children with non-high-risk BCP-ALL with available cytogenetic data and MRD studied at the end-of-induction (EOI) by multicolor flow cytometry (MFC) were included...

INTRODUCTION: Assessing the treatment response of glioblastoma multiforme during immunotherapy (IT) is an open issue. Treatment response assessment maps (TRAMs) might help distinguish true tumor progression (TTP) and pseudoprogression (PsP) in this setting. METHODS: We recruited 16 naïve glioblastoma patients enrolled in a phase II trial consisting of the Stupp protocol (a standardized treatment for glioblastoma involving combined radiotherapy and chemotherapy with temozolomide, followed by adjuvant temozolomide) plus IT with dendritic cells...

With the growing demand for robots in the industrial field, robot-related technologies with various functions have been introduced. One notable development is the implementation of robots that operate in collaboration with human workers to share tasks, without the need of any physical barriers such as safety fences. The realization of such collaborative operations in practice necessitates the assurance of safety if humans and robots collide. Thus, it is important to establish criteria for such collision scenarios to ensure robot safety and prevent injuries...

INTRODUCTION: Rhinophonia aperta may result from velopharyngeal insufficiency. Neuromuscular electrical stimulation (NMES) has been discussed in the context of muscle strengthening. The aim of this study was to evaluate in healthy subjects whether NMES can change the velopharyngeal closure pattern during phonation and increase muscle strength. METHOD: Eleven healthy adult volunteers (21-57 years) were included. Pressure profiles were measured by high resolution manometry (HRM): isolated sustained articulation of /a/ over 5 s (protocol 1), isolated NMES applied to soft palate above motor threshold (protocol 2) and combined articulation with NMES (protocol 3)...

Aneurysmal subarachnoid hemorrhage (SAH) is a critical condition associated with high mortality rates. Hypertension is a significant risk factor for SAH development and recurrence following coil embolization for a ruptured aneurysm. While reduction of salt consumption is crucial for managing hypertension, it often compromises food taste. Anodal electrical taste stimulation (ETS) has been proposed to enhance taste perception without altering salt content. We present the case of a 69-year-old female SAH patient with a ruptured aneurysm at the anterior communicating artery who underwent coil embolization and in whom we tested ETS's efficacy in enhancing the salt taste perception on day 42 after the procedure...

BACKGROUND: Male sperm DNA fragmentation (SDF) may be associated with assisted reproductive technology (ART) outcomes, but the impact of SDF on the occurrence of aneuploid-related miscarriage remains controversial. METHODS: Genome-wide single-nucleotide polymorphism-based chromosomal microarray analysis was performed on 495 miscarried chorionic villus samples undergone IVF/ICSI treatment from the Reproductive Medicine Center of the First Affiliated Hospital of Zhengzhou University...

BACKGROUND: A key strategy for quality improvement is drug use evaluation, which looks at the safe, appropriate use of medication principles. Tenofovir/Lamivudine/Dolutegravir (TLD-FDC) usage has not yet been sufficiently examined in published literature. The purpose of this study was to assess how TLD were used by HIV-positive patients Using WHO drug use evaluation standards in Lumame Primary Hospital, North West Ethiopia. METHODS: Using WHO drug use evaluation standards, a retrospective study design was used to evaluate the appropriateness of TLD use...

OBJECTIVES: The primary objective was to determine whether obliteration of the epitympanic area and mastoid cavity during canal wall up (CWU) cholesteatoma surgery reduces the rate of recurrent and residual cholesteatoma compared to not obliterating the same area. The secondary objective was to compare postoperative hearing outcomes between both techniques. METHODS: A retrospective cohort study was conducted in a tertiary referral center. One-hundred-fourty-three ears were included of patients (≥18y) who underwent a CWU tympanomastoidectomy for cholesteatoma with or without bony obliteration between January 2015 and March 2020 in the University Medical Center Utrecht...

BACKGROUND: Early guidance recommended a bolus of intravenous heparin at the beginning of leadless pacemaker (LP) implantation procedures. However, due to concern about bleeding complications, more recent practice has tended toward omitting the bolus and only running a continuous heparin infusion through the introducer sheath. The impact of omitting the heparin bolus on procedural outcomes is not clear. METHODS: We reviewed all Medtronic Micra LP implants at our institution from 9/2014 to 9/2022...

Attention deficit and hyperactive disorder (ADHD) is a chronic neurodevelopmental disorder characterized by inattention, hyperactivity-impulsivity, and working memory deficits. Social dysfunction is one of the major challenges faced by children with ADHD. It's found that children with ADHD perform less well than typically developing children on facial expression recognition (FER) tasks. Generally, children with ADHD have some difficulties in FER, while some researches suggest that they have no significant differences in accuracy of specific emotion recognition with typically developing children...

OBJECTIVE: People detained in short-term police custody often have complex health conditions that may necessitate emergency care, yet little is known about their management in EDs. The present study aimed to understand ED doctors' experiences and perceptions regarding the appropriateness and management of detainee transfers from police watch-houses to the EDs. METHODS: A qualitative descriptive study, using semi-structured interviews undertaken with ED doctors working in five purposively sampled EDs across Queensland, Australia...

Muscle-specific kinase myasthenia gravis (MuSK MG) is caused by autoantibodies against MuSK in the neuromuscular junction (NMJ). MuSK MG patients have fluctuating, fatigable skeletal muscle weakness, in particular of bulbar muscles. Severity differs greatly between patients, in spite of comparable autoantibody levels. One explanation for inter-patient and inter-muscle variability in sensitivity might be variations in compensatory muscle responses. Previously, we developed a passive transfer mouse model for MuSK MG...

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a significant clinical, economic, and human burden. The JAK1 Atopic Dermatitis Efficacy and Safety (JADE) program's Phase 3 trials demonstrated that as a treatment for moderate-to-severe AD in adults with previous exposure to immunotherapy, abrocitinib showed superior efficacy and safety compared with standard of care (SoC), consisting of topical corticosteroids. This study assessed the cost-effectiveness of abrocitinib with SoC versus SoC alone for this patient population in Japan from a societal perspective...
