Fertility preservation (FP) services are part of comprehensive care for those newly diagnosed with cancer. The capacity to offer these services to children and adolescents with cancer is unknown.

A cross-sectional survey was sent to 220 Children's Oncology Group member institutions regarding institutional characteristics, structure and organization of FP services, and barriers to FP. Standard descriptive statistics were computed for all variables. The association between site-specific factors and selected outcomes was examined using multivariable logistic regression.

One hundred forty-four programs (65.5%) returned surveys. Fifty-three (36.8%) reported a designated FP individual or team. Sperm banking was offered at 135 (97.8%) institutions, and testicular tissue cryopreservation at 37 (27.0%). Oocyte and embryo cryopreservation were offered at 91 (67.9%) and 62 (46.6%) institutions, respectively; ovarian tissue cryopreservation was offered at 64 (47.8%) institutions. The presence of dedicated FP persononstrates that existing infrastructure is inadequate to offer comprehensive services to patients. We discuss modifiable factors to improve patient access to FP.Objective On-bike systems warning cyclists about critical situations are a promising approach to improve safety. The chosen warning modality might strongly influence whether the cyclist accepts the system. So far, cyclists' warning preferences have not been analyzed based on field data. They were only analyzed through web-based surveys or a simulator study without including the three most promising signal types (i.e., visual, auditory and vibro-tactile). This study aims to evaluate the signal preferences for transmitting information to cyclists based on experience of the signals in the field.Method We conducted a field study where participants received signals of different signal types, i. e. visual, auditory and vibro-tactile signals, while cycling. learn more After completing the course, all participants answered a questionnaire on their subjective experiences of the signals. The participants separately cycled a 10 km long route in road traffic. All participants received 12 signals per modality on predefined GPS coordinates. The course covered different environmental conditions like loud ambient noise, gravel roads or high visual load.Results The data of 55 participants was analyzed. The participants chose the auditory and vibro-tactile signal over the visual signal. When asked, they significantly preferred an auditory warning to the other two signal types. The participants rated the auditory signal as most urgent and frequently associated it with warnings. Participants reported the visual signal as distracting from the cycling task and the vibro-tactile signals as difficult to distinguish from surface related vibrations.Conclusion The advantages of different signal modalities can be applied to develop information transmission systems in the cycling context. Our results show that the signal types have inherent qualities which may fit into different areas of application. This study highlights that the choice of a warning modality needs to be balanced on a combination of noticeability, criticality and personal preference.[Figure see text].[Figure see text].[Figure see text].[Figure see text].
The aim of this study was to determine the risk factors associated with the increase of the injury severity of powered two wheelers (PTW) riders when involved in a road accident in Portugal.

A retrospective analysis of 37769 PTW accidents that occurred in Portugal between 2010 and 2015 was performed. Injury severity was classified into 3 levels minor injury, severe injury and fatal injury. An ordered logistic regression was applied to identify the potential risk factors that can affect PTW accidents severity.

The following factors increase the chances of more severe injuries motorcycle in PTW category, rest days, 20 h to 5h59, clean and dry roads, Braga and Viana do Castelo regions, rural areas, bended roads, national roads, male rider, no helmet worn, blood alcohol content between 0.5 g/L and 0.8 g/L, truck involvement and other vehicle driver injured.

Special attention should be given to PTW accidents as they represent a large safety problem in Portugal. Understanding the risk factors that influenceto reduce the injury severity of PTW accidents in Portugal.
Autologous cell suspensions obtained by a stromal vascular fraction (SVF) and enzyme-free mechanical isolation (EMI) are an alternative in the treatment of burn wounds. In this study, we aimed to investigate the effect of autologous cell suspensions obtained by SVF and EMI on full-thickness skin burn wounds.

A total of 45 male Sprague-Dawley rats were divided into three groups, SVF group, EMI group, and SVF + EMI group. The groups were also classified as the first, second, and third week of the burn to reveal the effect of the treatment on the burn in the early, middle, and late stages. For treatment, 0.2 ml SVF or 0.2 ml EMI was injected subcutaneously into the burn lesions of the subjects. Histopathological examination was performed on the burn wounds taken at the end of the experiment, and Ki67, CD44, CD73, CD90, and CK17 expressions were evaluated.

Histological examination revealed that there was no improvement in the control samples, but the skin was multicellular, vascularization was present. Histologic scores in all groups was significantly better than control, and SVF + EMI was the best group in terms of recovery (
 < 0.05). Ki67, CK17, CD44, CD73, and CD90 expressions were significantly higher in the treatment groups compared to the control (
 < 0.05).

We found in our study that both applications significantly increased the healing of the burn wound. Moreover, SVF + EMI application provided more improvement than SVF or EMI alone.

The CLL14 study has established one-year fixed-duration treatment of venetoclax and obinutuzumab (Ven-Obi) for patients with previously untreated chronic lymphocytic leukemia. With all patients off treatment for at least three years, we report a detailed analysis of minimal residual disease (MRD) kinetics and long-term outcome of patients treated in the CLL14 study.

Patients were randomly assigned to receive six cycles of obinutuzumab with 12 cycles of venetoclax or 12 cycles of chlorambucil (Clb-Obi). Progression-free survival (PFS) was the primary end point. Key secondary end points included rates of undetectable MRD and overall survival. To analyze MRD kinetics, a population-based growth model with nonlinear mixed effects approach was developed.

Of 432 patients, 216 were assigned to Ven-Obi and 216 to Clb-Obi. Three months after treatment completion, 40% of patients in the Ven-Obi arm (7% in the Clb-Obi arm) had undetectable MRD levels < 10

These interlinkages have been discussed by the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), valuable references for multilateral negotiations in the United Nations Framework Convention on Climate Change (UNFCCC), whose Conference of the Parties (COP) convenes in November, and the UN Convention on Biological Diversity (CBD), whose COP convened in October. In the past year, in recognition of common challenges and opportunities, the IPCC and IPBES formally collaborated for the first time. Decision-making processes around these complex issues will be more effective if they integrate responses to climate change, biodiversity loss, and human development gaps at various spatial scales global, regional, national, and local.[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].Scientists started fewer new research projects in 2020.[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].
We compared 2 years of rituximab maintenance (RM) with a response-adapted postinduction approach in patients with follicular lymphoma who responded to induction immunochemotherapy.

We randomly assigned treatment-naïve, advanced-stage, high-tumor burden follicular lymphoma patients to receive standard RM or a response-adapted postinduction approach on the basis of metabolic response and molecular assessment of minimal residual disease (MRD). The experimental arm used three types of postinduction therapies for complete metabolic response (CMR) and MRD-negative patients, observation; for CMR and MRD-positive (end of induction or follow-up) patients, four doses of rituximab (one per week, maximum three courses) until MRD-negative; and for non-CMR patients, one dose of ibritumomab tiuxetan followed by standard RM. The study was designed as noninferiority trial with progression-free survival (PFS) as the primary end point.

Overall, 807 patients were randomly assigned. After a median follow-up of 53 months (raative.
