The past, present, and future of ecogeographic isolation between closely related Aquilegia plants

Abstract Quantifying the strength of the ecogeographic barrier is an important aspect of plant speciation research, and serves as a practical step to understanding the evolutionary trajectory of plants under climate change. Here, we quantified the extent of ecogeographic isolation in four closely related Aquilegia species that radiated in the Mountains of SW China and adjacent regions, often lacking intrinsic barriers. We used environmental niche models to predict past, present, and future species potential distributions and compared them to determine the degree of overlap and ecogeographic isolation. Our investigation found significant ecological differentiation in all studied species pairs except A. kansuensis and A. ecalacarata. The current strengths of ecogeographic isolation are above 0.5 in most cases. Compared with current climates, most species had an expanding range in the Last Glacial Maximum, the Mid Holocene, and under four future climate scenarios. Our results suggested that ecogeographic isolation contributes to the diversification and maintenance of Aquilegia species in the Mountains of northern and SW China and would act as an essential reproductive barrier in the future.
The Prevalence of Carbapenemase-Producing Microorganisms and Use of Novel Cephalosporins for the Treatment of Severe Infections Caused by Carbapenem-Resistant Gram-Negative Bacteria in a Pediatric Cardiac Intensive Care Unit

Background: The spread of carbapenem-resistant organisms (CROs) is an increasingly serious threat globally, especially in vulnerable populations, such as intensive care unit (ICU) patients. Currently, the antibiotic options for CROs are very limited, particularly in pediatric settings. We describe a cohort of pediatric patients affected by CRO infections, highlighting the important changes in carbapenemase production in recent years and comparing the treatment with novel cephalosporins (N-CEFs) to Colistin-based regimens (COLI). Methods: All patients admitted to the cardiac ICU of the Bambino Gesù Children’s Hospital in Rome during the 2016–2022 period with an invasive infection caused by a CRO were enrolled. Results: The data were collected from 42 patients. The most frequently detected pathogens were Pseudomonas aeruginosa (64%), Klebsiella pneumoniae (14%) and Enterobacter spp. (14%). Thirty-three percent of the isolated microorganisms were carbapenemase producers, with a majority of VIM (71%), followed by KPC (22%) and OXA-48 (7%). A total of 67% of patients in the N-CEF group and 29% of patients in the comparative group achieved clinical remission (p = 0.04). Conclusion: The increase over the years of MBL-producing pathogens in our hospital is challenging in terms of therapeutic options. According to the present study, N-CEFs are a safe and effective option in pediatric patients affected by CRO infections.
Acute kidney injury in diabetic patients: A narrative review

Diabetes mellitus (DM) is the most common cause of chronic kidney disease, which leads to end-stage renal failure worldwide. Glomerular damage, renal arteriosclerosis, and atherosclerosis are the contributing factors in diabetic patients, leading to the progression of kidney damage. Diabetes is a distinct risk factor for acute kidney injury (AKI) and AKI is associated with faster advancement of renal disease in patients with diabetes. The long-term consequences of AKI include the development of end-stage renal disease, higher cardiovascular and cerebral events, poor quality of life, and high morbidity and mortality. In general, not many studies discussed extensively “AKI in DM. ” Moreover, articles addressing this topic are scarce. It is also important to know the cause of AKI in diabetic patients so that timely intervention and preventive strategies can be implemented to decrease kidney injury. Aim of this review article is to address the epidemiology of AKI, its risk factors, different pathophysiological mechanisms, how AKI differs between diabetic and nondiabetic patients and its preventive and therapeutic implications in diabetics. The increasing occurrence and prevalence of AKI and DM, as well as other pertinent issues, motivated us to address this topic.
Benefits of Treadmill Training for Patients with Down Syndrome: A Systematic Review

Background: The objective of this study was to evaluate the effectiveness of various results of treadmill training in children and adults with Down syndrome (DS). Methods: To provide an overview of this effectiveness, we conducted a systematic literature review of studies in which participants with DS from all age groups received treadmill training, alone or combined with physiotherapy. We also looked for comparisons with control groups of patients with DS who did not undergo treadmill training. The search was performed in medical databases: PubMed, PEDro, Science Direct, Scopus, and Web of Science, and included trials published until February 2023. Following PRISMA criteria, the risk of bias assessment was conducted using a tool developed by the Cochrane Collaboration for RCT. The selected studies presented multiple outcomes with differences in methodology; therefore, we were not able to conduct any sort of data synthesis, so we present measures of treatment effect as mean differences and corresponding 95% confidence intervals. Results: We selected 25 studies for the analysis with a total number of 687 participants, and identified 25 different outcomes which are presented in a narrative manner. In all outcomes we observed positive results favoring the treadmill training. Discussion: Introducing treadmill exercise into typical physiotherapy generates improvement in mental and physical health of people with DS.
Non-invasive grading of brain tumors using online support vector machine with dynamic fuzzy rule-based parameters optimization

Graphical abstract Non-invasive grading of brain tumors provides a valuable understanding of tumor growth that helps choose the proper treatment. In this paper, an online method with an innovative optimization approach as well as a new and fast tumor segmentation method is proposed for the fully automated grading of brain tumors in magnetic resonance (MR) images. First, the tumor is segmented based on two characteristics of the tumor appearance (intensity and edges information). Second, the features of the tumor region are extracted. Then, the online support vector machine with the kernel (OSVMK) by dynamic fuzzy rule-based optimization of the parameters is used for the grading of tumors. The performance evaluation of the proposed tumor segmentation method was performed by manual segmentation using similarity criteria. Also, tumor grading results compared the proposed online method, the conventional online method, and the batch SVM with the kernel (batch SVMK) in terms of accuracy, precision, recall, specificity, and execution times. The segmentation results show a good correlation between the tumor segmented by the proposed method and by experts manually. Also, the grading results based on the accuracy, precision, recall, and specificity, 95.20%, 97.87%, 96.48%, and 96.45%, respectively, indicate the acceptable performance of the proposed method. The execution times of the introduced online method are much less than the batch SVMK. The method demonstrates the potential of fully automated tumor grading to provide a non-invasive diagnosis in order to determine the treatment strategy for the disease. So the physicians, according to the tumor’s grade, can match the treatment of the brain tumor to the patient’s individual needs and thus make the best course of treatment for each patient.
Genetic spectrum and clinical features of adult leukoencephalopathies in a Chinese cohort

Leukoencephalopathies are a group of heterogeneous disorders characterized by the degeneration of white matter, resulting in a variety of progressive neurological symptoms. To date, over 60 genes linked to genetic leukoencephalopathies have been discovered through whole‐exome sequencing (WES) and long‐read sequencing. Nonetheless, the genetic diversity and clinical variability of these disorders among various racial groups remain largely unknown. Therefore, this study aims to analyze the genetic spectrum and clinical features of Chinese adult leukoencephalopathies and compare the genetic profiles in different populations.
Predicting the Response of Children and Adolescents With ADHD to Methylphenidate: A Systematic Review

Objective: To report the characteristics associated with response to methylphenidate (MPH) in children and adolescents with ADHD. Methods: Studies reporting potentials predictors of response to MPH were searched in Medline and Embase from January 1998 to March 2022. Narrative synthesis was performed. Results: Fifty-seven reports of 46 studies totaling 6,656 ADHD patients were included. No association appears between response to MPH and age, gender, MPH dosage, ADHD subtype, comorbidities nor socioeconomic status when considering a specific patient. No conclusion could be drawn about body weight, ADHD severity, intelligence quotient, and parental symptoms of depression or ADHD. Conclusions: None of these potential predictors have proven their usefulness to predict response to MPH on an individual basis in clinical practice. In research, potential predictors should be measured, their association with response to MPH assessed, in order to control for confounding variables when modeling response to MPH.
Effect of possible risk factors for pharyngocutaneous fistula after total laryngectomy of laryngeal carcinomas and surgical wound infection: A meta‐analysis

A meta‐analysis study to assess the effect of possible risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy of laryngeal carcinoma. A comprehensive literature examination till January 2023 was implemented and 1794 linked studies were appraised. The picked studies contained 3140 subjects with total laryngectomy of laryngeal carcinomas in the picked studies' baseline, 760 of them were PCF, and 2380 were no PCF. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of possible risk factors for PCF after total laryngectomy of laryngeal carcinomas and surgical wound infection after total laryngectomy of laryngeal carcinoma by the dichotomous and continuous styles and a fixed or random model. The PCF had a significantly higher surgical wound infection (OR, 6.34; 95% CI, 1.89–21.27, P = .003) compared with the no PCF in total laryngectomy of laryngeal carcinomas. The smoking (OR, 1.73; 95% CI, 1.15–2.61, P = .008), and preoperative radiation (OR, 1.90; 95% CI, 1.37–2.65, P < .001) had significantly higher PCF as a risk factor in total laryngectomy of laryngeal carcinomas. The preoperative radiation had a significantly lower spontaneous PCF closure (OR, 0.33; 95% CI, 0.14–0.79, P = .01) compared with the no preoperative radiation in total laryngectomy of laryngeal carcinomas. However, the neck dissection (OR, 1.34; 95% CI, 0.75–2.38, P = .32), and alcohol intake (OR, 1.95; 95% CI, 0.76–5.05, P = .17), had no significant effect on PCF in total laryngectomy of the PCF had a significantly higher surgical wound infection, and preoperative radiation had a significantly lower spontaneous PCF closure in total laryngectomy of laryngeal carcinomas. Smoking and preoperative radiation were shown to be risk factors for PCF, however, neck dissection and alcohol intake were not shown to be risk factors for PCF in total laryngectomy of laryngeal carcinomas. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta‐analysis was with low sample sizes.
Renal MRI: From Nephron to NMR Signal

Renal diseases pose a significant socio‐economic burden on healthcare systems. The development of better diagnostics and prognostics is well‐recognized as a key strategy to resolve these challenges. Central to these developments are MRI biomarkers, due to their potential for monitoring of early pathophysiological changes, renal disease progression or treatment effects. The surge in renal MRI involves major cross‐domain initiatives, large clinical studies, and educational programs. In parallel with these translational efforts, the need for greater (patho)physiological specificity remains, to enable engagement with clinical nephrologists and increase the associated health impact. The ISMRM 2022 Member Initiated Symposium (MIS) on renal MRI spotlighted this issue with the goal of inspiring more solutions from the ISMRM community. This work is a summary of the MIS presentations devoted to: 1) educating imaging scientists and clinicians on renal (patho)physiology and demands from clinical nephrologists, 2) elucidating the connection of MRI parameters with renal physiology, 3) presenting the current state of leading MR surrogates in assessing renal structure and functions as well as their next generation of innovation, and 4) describing the potential of these imaging markers for providing clinically meaningful renal characterization to guide or supplement clinical decision making. We hope to continue momentum of recent years and introduce new entrants to the development process, connecting (patho)physiology with (bio)physics, and conceiving new clinical applications. We envision this process to benefit from cross‐disciplinary collaboration and analogous efforts in other body organs, but also to maximally leverage the unique opportunities of renal physiology.
Radiological response of leptomeningeal metastases according to revised RANO criteria is associated with overall survival in breast cancer patients

Assessment of treatment response in patients (pts) with leptomeningeal metastases (LM) represents a significant challenge and standardized criteria are needed. In 2017, the RANO LM Working Group proposed a standardized scorecard to evaluate MRI findings (further simplified in 2019). Here, we aim to validate the prognostic impact of response to treatment assessed using this tool in a multicentric cohort of breast cancer (BC) pts. Pts with BC‐related LM diagnosed at two institutions between 2005 and 2018 were identified. Baseline and follow‐up MRI scans were centrally reviewed and response assessment was evaluated using 2019 revised RANO LM criteria. A total of 142 pts with BC‐related LM and available baseline brain MRI imaging were identified; 60 of them had at least one follow‐up MRI. In this subgroup, median overall survival (OS) was 15.2 months (95%CI 9.5‐21.0). At first re‐evaluation, radiological response by RANO criteria was: complete response (CR) in 2 pts (3%), partial response (PR) in 12 (20%), stable disease (SD) in 33 (55%) and progression of disease (PD) in 13 (22%). Median OS was 31.1 months (HR 0.10, 95%CI 0.01‐0.78) in pts with CR, 16.1 months (HR 0.41, 95%CI 0.17‐0.97) in pts with PR, 17.9 months (HR 0.45, 95%CI 0.22‐0.91) in pts with SD and 9.5 months in pts with PD (P = .029). A second blinded evaluation showed a moderate interobserver agreement (K = 0.562). Radiological response according to 2019 RANO criteria is significantly associated with OS in pts with BC‐related LM, thus supporting the use of this evaluation tool both in trials and clinical practice.
Effects of Time Pressure, Reward, and Information Involvement on User Management of Fake News on a Social Media Platform

This study examined the effects of time pressure, reward, and information involvement on individual fact-checking behavior within a social media platform. We used a four-factor mixed-design experiment to examine fact-checking performances of 144 participants for 36 ambiguous social platform statements, all of which were news statements of social events or of common-sense knowledge collected from the internet and selected through pre-test screening. We measured the participants’ total number of fact-checked statements and their judgment accuracy of those statements. We also measured participants’ decision time for making judgments, and their judgment confidence levels. Participants’ social presence, time pressure, and information involvement were significantly related to the number of statements they fact-checked. Their perceived social presence on a social media platform reduced their fact-checking. Time pressure increased the frequency of fact-checking and weakened the impact of social presence. Participants were less likely to fact-check statements when they had high involvement with the information, due to overconfidence. Statements with high information involvement had longer decision-making times. These findings provide a basis for designing ways to display and push information to increase an individual’s awareness of a need to fact-check ambiguous information in a new social media environment.
Longitudinal associations between insomnia, cannabis use and stress among US veterans

Insomnia is highly prevalent among military veterans, with rates nearly double that of civilian populations. Insomnia typically co‐occurs with other psychological problems, including substance use (e.g. cannabis) and perceived stress. Much of the research focused on insomnia, stress and cannabis use explores cannabis as a sleep aid and a mechanism for stress relief. However, recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, cannabis use and perceived stress, yet few longitudinal studies exist. Using a sample of 1105 post‐9/11 veterans assessed over four time points across 12 months, we used latent difference score modelling to examine proportional change between insomnia, perceived stress and cannabis use. Results revealed a complex interplay between all three constructs. In particular, we show that higher prior levels of insomnia are associated with greater increases in perceived stress, and greater prior levels of stress are associated with greater increases in cannabis use. Perhaps more importantly, our results also point to cannabis use as a catalyst for greater increases in both stress and insomnia severity. Our results suggest there may be both benefits and costs of cannabis use among veterans. Specifically, for veterans who experience chronic sleep problems, perceived stress may become overwhelming, and the benefit of stress reduction from increased cannabis use may come at the cost of increasing insomnia symptomology.
Understanding research methods, limitations, and applications of drug data collected by the National Forensic Laboratory Information System (NFLIS‐Drug)

The National Forensic Laboratory Information System (NFLIS) is a drug surveillance program of the US Drug Enforcement Administration that systematically collects data on drugs that are seized by law enforcement and submitted to and analyzed by the Nation's forensic laboratories (NFLIS‐Drug). NFLIS‐Drug data are increasingly used in predictive modeling and drug surveillance to examine drug availability patterns. Given the complexity of the data and data collection, there are some common methodological pitfalls that we highlight with the aim of helping researchers avoid these concerns. The analysis done for this Technical Note is based on a review of the scientific literature that includes 428 unique, refereed article citations in 182 distinct journals published between January 1, 2005, and April 30, 2021. Each article was analyzed according to how NFLIS‐Drug data were mentioned and whether NFLIS‐Drug data were included. A sample of 37 articles was studied in‐depth, and data issues were summarized. Using examples from the literature, this Technical Note highlights eight broad concerns that have important implications for the proper applications, interpretations, and limitations of NFLIS‐Drug data with suggestions for improving research methods and accurate reporting of forensic drug data. NFLIS‐Drug data are timely and provide key information to inform drug use trends across the United States; however, our present analysis shows that NFLIS‐Drug data are misunderstood and represented in the literature. In addition to highlighting these issues, DEA has created several resources to assist NFLIS data users and researchers, which are summarized in the discussion.
Antisense Oligonucleotide Silencing Reverses Abnormal Neurochemistry in Spinocerebellar Ataxia 3 Mice

Spinocerebellar ataxia type 3 (SCA3) is the most common dominantly inherited ataxia, and biomarkers are needed to noninvasively monitor disease progression and treatment response. Anti‐ATXN3 antisense oligonucleotide (ASO) treatment has been shown to mitigate neuropathology and rescue motor phenotypes in SCA3 mice. Here, we investigated whether repeated ASO administration reverses brainstem and cerebellar neurochemical abnormalities by magnetic resonance spectroscopy (MRS).
Biochemical and functional characterization of skeletal muscle cells differentiated from tonsil‐derived mesenchymal stem cells

Human tonsils are a readily accessible source of stem cells for the potential treatment of skeletal muscle disorders. We reported previously that tonsil‐derived mesenchymal stem cells (TMSCs) can differentiate into skeletal muscle cells (SKMCs), which renders TMSCs promising candidates for cell therapy for skeletal muscle disorders. However, the functional properties of the myocytes differentiated from mesenchymal stem cells have not been clearly evaluated. In this study we investigated whether myocytes differentiated from TMSCs (skeletal muscle cells derived from tonsil mesenchymal stem cells [TMSC‐SKMCs]) exhibit the functional characteristics of SKMCs.
Short and Long-term Efficacy of 3-dimensional Laparoscopic-assisted D2 Radical Gastrectomy Under the Guidance of Membrane Anatomy for Locally Advanced Gastric Cancer

Background: Both 3-dimensional (3D) laparoscopy and membrane anatomy are topics of great interest in the treatment of gastric cancer. The purpose of this study was to evaluate the safety, feasibility, and efficacy of 3D laparoscopic-assisted D2 radical gastrectomy for locally advanced gastric cancer (LAGC) under the guidance of membrane anatomy. Patients and Methods: Retrospectively analyzed the clinical data of 210 patients who underwent 2-dimensional (2D)/3D laparoscopic-assisted D2 radical gastrectomy under the guidance of membrane anatomy for LAGC. Compared the differences between the two groups in surgical outcomes, postoperative recovery, postoperative complications, and 2-year overall survival and disease-free survival. Results: The baseline data of the 2 groups were comparable (P > 0.05). The amount of intraoperative bleeding in the 2D and 3D laparoscopy groups was 100.1 ± 48.75 mL and 74.29 ± 47.33 mL, respectively, with a significant difference between the two groups (P < 0.001). The time to first exhaust and first liquid diet intake and length of postoperative hospital stay was shorter in the 3D laparoscopy group, with significant differences between the two groups [3 (3-3) days vs 3(3-2) days, P = 0.009; 7 (8-7) days vs 6 (7-6) days, P < 0.001; and 13 (15-11) days vs 10 (11-9) days, P < 0.001]. There were no significant differences in operation time, number of lymph node dissections, incidence of postoperative complications, or 2-year overall survival and disease-free survival between the two groups (P > 0.05). Conclusions: Three-dimensional laparoscopic-assisted D2 radical gastrectomy for LAGC under the guidance of membrane anatomy is safe and feasible. It can reduce intraoperative bleeding, accelerate postoperative recovery, and does not increase operative complications, the long-term prognosis is similar to that of the 2D laparoscopy group.
