Computed tomography analysis showed that the subchondral bone's epiphysis in the control group had sclerotic change, not observed in the septide group.

The administration of septide ameliorates OA progression through preventing subchondral bone sclerosis.

Military members' knowledge of concussion signs and symptoms may be critical to appropriate concussion identification and health-seeking behavior, particularly for those in leadership roles. The current study aimed to characterize concussion knowledge and attitudes among future military officers undergoing U.S.-based Reserve Officers' Training Corps (ROTC) training.

Army and Air Force ROTC cadets at 2 large, public universities were utilized for a survey-based observational study. The study was approved by the institutional review board at both university research sites. Cadets completed a modified Rosenbaum Concussion Knowledge and Attitude Survey to obtain cadets' Concussion Knowledge Index and Concussion Attitude Index, where higher scores are preferable. Cadets' concussion knowledge and attitudes were characterized via descriptive statistics.

Cadets (n = 110) had a mean Concussion Knowledge Index of 18.8 ± 3.2 (range = 9-23, out of 25). Potentially detrimental misconceptions included belief that typically concussion symptoms no longer persist after 10 days (79.1%) and brain imaging shows visible physical damage following concussion (74.5%). Mean Concussion Attitude Index was 60.6 ± 7.4 (range = 46-75, out of 75). In general, cadets reported higher agreement with safe concussion behavior than what they believe peers would report.

Cadets were found to have a high concussion knowledge, yet common misconceptions remained. Cadets consistently reported safe choices but were less sure that peers felt similarly; future investigations should evaluate ROTC concussion social norms and education should note peers' beliefs supporting safe concussion attitudes.

Breast Implant Illness (BII) is a term used to describe a variety of symptoms by patients with breast implants for which there are no abnormal physical or laboratory findings to explain their symptoms. There currently exists a difference of opinion among clinicians and patients concerning the diagnosis and treatment of patients self-reporting BII.

The first aim of this study was to determine if there is a valid indication for "en bloc" capsulectomy in patients self-reporting BII and if the type of capsulectomy performed alters long-term symptom improvement. The second goal was to identify any clinical laboratory differences between the cohorts. This study was funded by the Aesthetic Surgery Education and Research Foundation (ASERF).

A prospective blinded study enrolled 150 consecutive subjects divided equally into three cohorts (A) women with systemic symptoms they attribute to their implants who requested implant removal, (B) women with breast implants requesting removal or exchange who do not have sym symptoms after explantation and that this improvement persists for at least 6 months. This improvement in self-reported systemic was seen regardless of the type of capsulectomy performed.

This study addresses one of the most discussed questions by plastic surgeons, patients, their advocates, and social media. The findings show that patients who self-report BII demonstrate a statistically significant improvement in their symptoms after explantation and that this improvement persists for at least 6 months. This improvement in self-reported systemic was seen regardless of the type of capsulectomy performed.Sample size calculations from high-profile surgical RCTs that used a patient-reported outcome measure as primary outcome were reviewed systematically against Difference ELicitation in TriAls (DELTA2) standards, with a focus on target differences. In this sample of trials, there was frequent use of suboptimal methods to determine the target difference, and sample size calculations were generally not reported to DELTA2 standards. This risks over-recruitment and/or erroneous trial conclusions, which clinicians should be aware of when interpreting published trials.Decorin, a small leucine-rich proteoglycan produced by decidual cells restrains trophoblast differentiation, migration and invasiveness of extra-villous trophoblast cells. Decidual overproduction of decorin is associated with preeclampsia, and elevated decorin levels in maternal plasma are a predictive biomarker of preeclampsia. Furthermore, decorin plays an autocrine role in maturation of human endometrial stromal cells into decidual cells. Thus, a balanced decorin production by the decidua is critical for healthy pregnancy. However, the molecular mechanisms regulating decorin production by the decidua are unclear. Interleukin-1 beta is an inflammation-associated multi-functional cytokine, and is reported to induce decidualization in primates. Hence, the present study was designed (i) to test if exogenous Interleukin-1 beta stimulated decorin production by human endometrial stromal cells; and if so, (ii) to identify the cellular source of Interleukin-1 beta in first trimester decidual tissue; (iii) to identify the downstream molecular partners in Interleukin-1 beta mediated decorin production by human endometrial stromal cells. Results revealed that (i) amongst multiple pro-inflammatory cytokines tested, Interleukin-1 beta alone stimulated decorin production by these cells; (ii) both macrophages and decidual cells in first trimester decidua produced Interleukin-1 beta; (iii) Interleukin-1 beta mediated decorin production was dependent on Interleukin-1 receptor activation, followed by activation and nuclear translocation of nuclear factor kappa B and its binding to the decorin promoter. These results reveal that Interleukin-1 beta plays a novel role in inducing decorin production by human endometrial stromal cells by activating nuclear factor kappa B.

The COVID-19 pandemic and associated quarantine measures highly impacted parental psychological well-being. Parents of children with chronic diseases might be specifically vulnerable as they already face multiple challenges to provide adequate care for their child. The research questions of the current study were twofold (a) to examine whether parents of children with a chronic disease experienced more anxiety and depression compared to parents of healthy children and (b) to examine a series of risk factors for worsened well-being (i.e., depression, anxiety, and sleep problems), such as sociodemographic variables, COVID-19-specific variables (i.e., financial worries, living space, and perceived quality of health care), and parental psychological experiences (i.e., parental burn-out and less positive parenting experiences).

Parents of children with a chronic disease (i.e., the clinical sample; N = 599 and 507 for Research Questions 1 and 2, respectively) and parents of healthy children (i.e., the reference sample N = 417) filled out an online survey.

Findings demonstrated that the parents in the clinical sample reported higher levels of anxiety than parents in the reference sample. Analyses within the clinical sample indicated that COVID-19-specific stressors and parental psychological experiences were associated with higher levels of anxiety, depression, and sleep problems. Mediation analyses furthermore indicated that the association of COVID-19-specific stressors with all outcome measures was mediated by parental burn-out.

Parents of children with a chronic disease constitute a vulnerable group for worse well-being during the current pandemic. Findings suggest interventions directly targeting parental burn-out are warranted.

Otitis media with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) is a new category of otitis media in which cases of otitis media due to ANCA-associated vasculitis (AAV) are classified, regardless of ANCA variant or ANCA serotype. We aimed to describe the clinical features and course of patients with OMAAV and identify factors associated with hearing outcomes.

We retrospectively analysed 30 patients with OMAAV, classified based on the criteria proposed by the Japan Otological Society in 2016.

Single-positive myeloperoxidase-ANCA, single-positive proteinase 3-ANCA, double-positive ANCA, and double-negative ANCA were identified in 47%, 33%, 7%, and 13% of the patients, respectively. All patients subjected to audiometry showed hearing impairments, and 85% were affected bilaterally. Mixed- and sensorineural-type hearing impairments were identified in 80% and 20% of impaired ears, respectively. Hypertrophic pachymeningitis (HPM) was identified in 37% of the patients. Immunosuppressive therapy was administered to 93% of patients, and the median air conduction hearing levels at pre- and post-treatment were 66.1 dB and 43.4 dB, respectively, indicating significant hearing improvements. HPM and a long interval between disease onset and treatment initiation were significantly correlated with poor hearing prognosis.

OMAAV develops under any type of ANCA-serology and typically causes mixed or sensorineural bilateral hearing loss. The early initiation of immunosuppressive therapy and the absence of HPM were associated with good hearing outcomes.

We propose that computational models based on assemblies of neurons can serve as a blueprint for bridging these two scales. We discuss recently developed computational models of assemblies that have been demonstrated to mediate higher cognitive functions such as the processing of simple sentences, to be realistically realizable by neural activity, and to possess general computational power.We review mechanisms for preemptive acclimation in plants and propose a conceptual model linking developmental and evolutionary ecology with the acquisition of information through sensing of cues and signals. The idea is that plants acquire much of the information in the environment not from individual cues and signals but instead from their joint multivariate properties such as correlations. If molecular signalling has evolved to extract such information, the joint multivariate properties of the environment must be encoded in the genome, epigenome and phenome. We contend that multivariate complexity explains why extrapolating from experiments done in artificial contexts into natural or agricultural systems almost never works for characters under complex environmental regulation biased relationships among the state variables both in time and space create a mismatch between the evolutionary history reflected in the genotype and the artificial growing conditions in which the phenotype is expressed. Our model can generate testable hypotheses bridging levels of organization.
