Frequency following response

To clarify whether changes in frequency of going out due to the COVID-19 pandemic affect ikigai (sense of purpose in life) and mental health in Japanese middle-aged and older adults. In a questionnaire survey mailed to 16,866 adults aged > 40 years in Japan in September 2020, 7,973 responses were received (response rate, 47.3%) in October 2020. Following exclusions, data from 6,978 individuals (50.6% female, mean age 67.8 ± 12.2 years) were available for analysis...

Purpose Although many patients with mild traumatic brain injury (mTBI) suffer from post-concussional syndrome(PCS) including abnormal emotional responses, most conventional imaging studies fail to detect any causative brain lesion. We hypothesized that event-related electroencephalography (EEG) recordings with time-frequency analysis would show a distinguishable pattern in mTBI patients with PCS compared with normal healthy controls. Methods EEG signals were collected from a total of 18 subjects: eight mTBI patients with PCS and ten healthy control subjects...

Reservoirs, heavily influenced by artificial management, often harbor phytoplankton assemblages dominated by cyanobacteria or dinoflagellates, triggering significant changes in aquatic ecosystems. However, due to limited sampling frequency and insufficient attention to species composition, the bloom processes and key characteristics of phytoplankton community structure have not been systematically elucidated. During the low-water level period when blooms are most likely to occur (June to September) in a tributary bay of the Three Gorges Reservoir, daily sampling was conducted to investigate phytoplankton community composition, identify significant environmental factors, and evaluate important structure characteristics of phytoplankton community...

STUDY QUESTION: Does medically assisted reproduction (MAR) use among cisgender women differ among those with same-sex partners or lesbian/bisexual identities compared to peers with different-sex partners or heterosexual identities? SUMMARY ANSWER: Women with same-sex partners or lesbian/bisexual identities are more likely to utilize any MAR but are no more likely to use ART (i.e. IVF, reciprocal IVF, embryo transfer, unspecified ART, ICSI, and gamete or zygote intrafallopian transfer) compared to non-ART MAR (i...

PURPOSE: Prior evidence has shown that neural factors contribute to the loss of muscle force after skeletal-muscle disuse. However, little is known about the specific neural mechanisms altered by disuse. Persistent inward current (PIC) is an intrinsic property of motoneurons responsible for prolonging and amplifying the synaptic input, proportionally to the level of neuromodulation, thus influencing motoneuron discharge rate and force production. Here, we hypothesized that short-term unilateral lower-limb suspension (ULLS) would reduce the neuromodulatory input associated with PICs, contributing to the reduction of force generation capacity...

BACKGROUND: In response to the rapid aging population and increasing number of cancer patients, discussions on dignified end-of-life (EoL) decisions are active around the world. Therefore, this study aimed to identify the differences in EoL care patterns between types of hospice used for cancer patients. METHODS: In this population-based cohort study, the Korean National Health Insurance Service cohort data containing all registered cancer patients who died between 2017 and 2021 were used...

PURPOSE: This study develops the evidence-base of interventions for inappropriate sexualised behaviour following brain injury involving adolescents. MATERIALS AND METHODS: We describe a Single-Case Multiple Baseline Design intervention of Positive Behavioural Support (PBS) across settings. It involves a 16 year old adolescent who had a severe Traumatic Brain Injury (TBI) and presented with sexualised talk and touch. PBS may potentially be a successful intervention to remediate this...

BACKGROUND/AIM: The knowledge of dental students about managing traumatic dental injuries (TDIs) may not be uniform, depending on global location and dental education. The aim of this study was to evaluate the level of knowledge of undergraduate and postgraduate students specializing in endodontics and pediatric dentistry at 10 dental schools in 10 countries about the 2020 International Association of Dental Traumatology (IADT) guidelines regarding the management of TDIs. MATERIALS & METHODS: A previously published questionnaire was used in the current survey...

BACKGROUND: Asthma classification into different sub-phenotypes is important to guide personalized therapy and improve outcomes. OBJECTIVES: This study sought to further explore asthma heterogeneity through determination of multiple patient groups by using novel machine learning (ML) approaches and large-scale real-world data. METHODS: We used electronic health records of patients with asthma followed at the Cleveland Clinic between 2010 and 2021...

BACKGROUND: Previous studies have identified the consumption of country foods (hunted/harvested foods from the land) as the primary exposure source of perfluoroalkyl acids (PFAA) in Arctic communities. However, identifying the specific foods associated with PFAA exposures is complicated due to correlation between country foods that are commonly consumed together. METHODS: We used venous blood sample data and food frequency questionnaire data from the Qanuilirpitaa? ("How are we now?") 2017 (Q2017) survey of Inuit individuals <mml:math xmlns:mml="https://www...

Background: Telemedicine improves access to specialized medical expertise, as required for paroxysmal disorders. The Epilepsy Network Hessen Evaluation (ENHE) is a pilot cross-sectoral teleconsultation network connecting primary neurologists and pediatricians with epilepsy centers in Hessen, a federal German state. Methods: We prospectively and longitudinally evaluated telehealthcare in the ENHE. Participating physicians rated each consultation for satisfaction and impact on further management. The survey was administered at each consultation and 3 months later...

BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well-established treatment for the motor symptoms of Parkinson's disease (PD). While PD is primarily characterized by motor symptoms such as tremor, rigidity, and bradykinesia, it also involves a range of non-motor symptoms, and anxiety is one of the most common. The relationship between PD and anxiety is complex and can be a result of both pathological neural changes and the psychological and emotional impacts of living with a chronic progressive condition...

BACKGROUND: Real-world data on the effectiveness and safety of ustekinumab (UST) in ulcerative colitis (UC) are lacking in Latin America. In this study, we aimed to describe the effectiveness and safety of UST in a real-world multicenter cohort of Brazilian patients with UC. METHODS: We conducted a multicenter retrospective observational cohort study, including patients with moderate-to-severe UC (total Mayo score 6-12, with an endoscopic subscore of 2 or 3) who received UST...

Background: To assess the efficacy of autologous hematopoietic stem cell transplantation (auto-HSCT) in multiple myeloma (MM) patients with acute renal failure. Materials and Methods: A retrospective single-center study included 64 patients (30 men, 34 women) with MM and kidney damage at the onset of the disease, aged 19 to 65 years (median 54), who underwent auto-HSCT from 2013 to 2019. 23 patients (36%) were dialysis-dependent at the time of diagnosis. The analysis was carried out in two groups: the "HD-" group (patients who were independent of hemodialysis during auto-HSCT, n = 54), and the "HD +" group (patients who underwent auto-HSCT while treated with programmed hemodialysis, n = 10)...

Blockade of the co-inhibitory receptor PD-1 enhances antitumor responses by boosting the function of antigen-specific T cells. Although rare, PD-1 blockade in patients with cancer can lead to exacerbation of infection-associated pathology. Here, we detail the case of a 38-year-old man who was enrolled in a clinical trial for assessment of the safety and activity of anti-PD-1 therapy for Kaposi sarcoma in people with HIV well-controlled on antiretroviral therapy. Less than a week after receiving the first dose of anti-PD-1 antibody (pembrolizumab), he presented with severe abdominal pain associated with sudden exacerbations of preexisting cytomegalovirus (CMV) enteritis and nontuberculous mycobacterial mesenteric lymphadenitis...

BACKGROUND: Rhabdomyosarcoma (RMS) is a rare cancer that develops in soft tissue, particularly skeletal muscle tissue and occasionally hollow organs like the bladder or uterus. Vincristine (VCR) is the main therapy used in treatment of RMS, it is an alkaloid produced from vinca and it is one of the most commonly prescribed drugs in pediatric oncology for the treatment of a number of tumors. The CYP3A5 enzyme is responsible for vincristine metabolism. The effect of CYP3A5 genetic polymorphism on the efficacy and toxicity of VCR on RMS patients still needs further research...

BACKGROUND: The adaptive cardiac resynchronization therapy (aCRT) algorithm enables synchronized left ventricular pacing (sLVP) to achieve fusion with intrinsic right ventricular activation. Although sLVP presents benefits over biventricular pacing, the adequate sLVP rate for better clinical outcomes remains unclear. We aimed to assess the association between sLVP rates and clinical outcomes. METHODS: Our study cohort included 271 consecutive patients, who underwent CRT implantation between April 2016 and August 2021...

We study the response of a quantitative trait to exponential directional selection in a finite haploid population, both at the genetic and the phenotypic level. We assume an infinite sites model, in which the number of new mutations per generation in the population follows a Poisson distribution (with mean Θ) and each mutation occurs at a new, previously monomorphic site. Mutation effects are beneficial and drawn from a distribution. Sites are unlinked and contribute additively to the trait. Assuming that selection is stronger than random genetic drift, we model the initial phase of the dynamics by a supercritical Galton-Watson process...

Preventing SARS-CoV-2 infection is of utmost importance in allogeneic hematopoietic cell transplantation patients (allo-HCT), given their heightened susceptibility to adverse outcomes associated with SARS-CoV-2 infection. However, limited data are available regarding the immune response to COVID-19 vaccines in these subjects, particularly concerning the generation and persistence of spike-specific memory response. Here, we analyzed the spike-specific memory B cells in a cohort of allo-HCT recipients vaccinated with multiple doses of the mRNA-1273 vaccine and monitored the spike-specific antibody response from baseline up to one month after the fourth dose...

Multi-drug-resistant (MDR) Acinetobacter baumannii is an opportunistic pathogen associated with hospital-acquired infections. Due to its environmental persistence, virulence, and limited treatment options, this organism causes both increased patient mortality and incurred healthcare costs. Thus, prophylactic vaccination could be ideal for intervention against MDR Acinetobacter infection in susceptible populations. In this study, we employed immunoinformatics to identify peptides containing both putative B- and T-cell epitopes from proteins associated with A...
