UNLABELLED: The aim of this study was to identify parameters influencing DNA extraction and PCR amplification efficiencies in an attempt to standardize Mucorales qPCR. The Fungal PCR Initiative Mucorales Laboratory Working Group distributed two panels of simulated samples to 26 laboratories: Panel A (six sera spiked with Mucorales DNA and one negative control serum) and Panel B (six Mucorales DNA extracts). Panel A underwent DNA extraction in each laboratory according to the local procedure and were sent to a central laboratory for testing using three different qPCR techniques: one in-house qPCR assay and two commercial assays (MucorGenius and Fungiplex). Panel B DNA extracts were PCR amplified in each laboratory using local procedures: nine in-house qPCR assays and two commercial kits (MucorGenius and MycoGENIE). All data were compiled and anonymously analyzed at the central laboratory. For Panel A, a total of six different automated platforms and five manual extraction methods were used. Positive rates were 64%, 70%, and 89%, for the MucorGenius, Fungiplex, and the in-house qPCR assay, respectively. Using a large volume of serum for DNA extraction provided the highest analytical sensitivity (82.5% for 1 mL compared with 62.7% for smaller volumes, P < 0.01). For Panel B, five in-house qPCR assays and two commercial kits had >78% positivity. Using larger PCR input volumes (≥7 μL) was associated with the highest sensitivity at 95.5% compared to 58.3% when lower input volumes were used (P < 0.01). Using larger sample volumes for nucleic acid extraction and DNA template volumes for PCR amplification significantly improves the performance of Mucorales qPCR when testing serum. IMPORTANCE: Mucormycosis is a life-threatening mold infection affecting immunosuppressed patients but also other patients with diabetes or trauma. Better survival is linked to shorter delays in diagnosis and treatment initiation. Detection of Mucorales-free DNA in serum or plasma using quantitative PCR allows a prompt diagnosis and earlier treatment. Several techniques and protocols of quantitative Mucorales PCR are used in Europe, and improving performance remains a common objective of laboratories participating in the fungal PCR Initiative Working Group. This study, which combined results from 26 laboratories in Europe, showed that the main parameters underpinning sensitivity are the preanalytical variables (volume of serum used for DNA extraction and DNA template volume), irrespective of the extraction platforms and qPCR assay/platform.

INTRODUCTION: Appendectomy for acute appendicitis is the most common surgical procedure performed during pregnancy. The primary treatment for acute appendicitis is emergency surgery, which can be particularly challenging due to altered anatomical conditions. Preoperative and postoperative care may require certain examinations due to pregnancy that are not standard within surgical practice or may be overlooked by the attending gynecologist. CASE PRESENTATION: A patient at 31 weeks of gestation presented to the obstetric clinic with an acute onset of acute appendicitis. After completing all necessary examinations and a thorough multidisciplinary evaluation, a successful laparoscopic appendectomy was performed. The subsequent hospitalization was complicated by the onset of uterine contractions, for which tocolysis was administered in combination with corticosteroid therapy to induce fetal lung maturity. CONCLUSION: In the presented case report, we demonstrate an example of the appropriate multidisciplinary approach with an analysis of the specific steps that should be taken to maximize the benefit for both the fetus and the mother, as well as the surgical team. In the discussion, we outline the steps that should be followed for patient benefit and forensic reasons.

Introduction. Vagal nerve stimulation (VNS) is a therapeutical option for the treatment of drug-resistant epileptic patients. The response to VNS varies from patient to patient and is difficult to predict. The proposed study is based on our previous work, identifying relative mean power in pre-implantation EEG as a reliable marker for VNS efficacy prediction in adult patients. Our study has two main tasks. Firstly, to confirm the utility of relative mean power as a feature correlating with VNS efficacy in children. The second is to validate the applicability of our prediction classifier, Pre-X-Stim, in the pediatric population. Material and Methods. We identified a group of children with drug-resistant epilepsy. We included only children in whom EEG contained photic stimulation (Task 1) or was recorded based on the defined acquisition protocol used for development Pre-X-Stim (Task 2). Relative mean powers were calculated. VNS responders and non-responders were compared based on relative mean powers' values. In the next step, we evaluate the utility of our classifier, Pre-X-Stim, in the children population. Results: We identified 57 children treated with VNS - 17 patients were recruited for the Task 1 and 7 patients for the Task 2. When focusing on relative mean powers in EEG spectra, we observed statistically significant differences in theta range. The Pre-X-Stim algorithm was able to predict VNS efficacy correctly in 6 out of 7 patients (the accuracy 83.3%, the sensitivity 75%, the specificity 100%). Conclusions. Based on our results, it seems that children and adults share a similar pattern of EEG relative mean power changes. These changes can be used for pre-implantation prediction of VNS efficacy.

BACKGROUND: Various explicit screening tools, developed mostly in central Europe and the USA, assist clinicians in optimizing medication use for older adults. The Turkish Inappropriate Medication use in oldEr adults (TIME) criteria set, primarily based on the STOPP/START criteria set, is a current explicit tool originally developed for Eastern Europe and subsequently validated for broader use in Central European settings. Reviewed every three months to align with the latest scientific literature, it is one of the most up-to-date tools available. The tool is accessible via a free mobile app and website platforms, ensuring convenience for clinicians and timely integration of updates as needed. Healthcare providers often prefer to use their native language in medical practice, highlighting the need for prescribing tools to be translated and adapted into multiple languages to promote optimal medication practices. OBJECTIVE: To describe the protocol for cross-cultural and language validation of the TIME criteria in various commonly used languages and to outline its protocol for clinical validation across different healthcare settings. METHODS: The TIME International Study Group comprised 24 geriatric pharmacotherapy experts from 12 countries. In selecting the framework for the study, we reviewed the steps and outcomes from previous research on cross-cultural adaptations and clinical validations of explicit tools. Assessment tools were selected based on both their validity in accurately addressing the relevant issues and their feasibility for practical implementation. The drafted methodology paper was circulated among the study group members for feedback and revisions leading to a final consensus. RESULTS: The research methodology consists of two phases. Cross-cultural adaptation/language validation phase follows the 8-step approach recommended by World Health Organization. This phase allows regions or countries to make modifications to existing criteria or introduce new adjustments based on local prescribing practices and available medications, as long as these adjustments are supported by current scientific evidence. The second phase involves the clinical validation, where participants will be randomized into two groups. The control group will receive standard care, while the intervention group will have their treatment evaluated by clinicians who will review the TIME criteria and consider its recommendations. A variety of patient outcomes (i.e., number of hospital admissions, quality of life, number of regular medications [including over the counter medications], geriatric syndromes and mortality) in different healthcare settings will be investigated. CONCLUSION: The outputs of this methodological report are expected to promote broader adoption of the TIME criteria. Studies building on this work are anticipated to enhance the identification and management of inappropriate medication use and contribute to improved patient outcomes.
The aim of this study was to compare selected ankle and knee kinematic and kinetic parameters before and a fter a prolonged exhaustive treadmill run between two groups of non-rearfoot footstrike pattern (NRFP) runners with different training volumes. Twenty-eight habitual NRFP runners were assigned to two groups based on their weekly training volume (Highly-trained (HT)/Moderately-trained (MT)). Participants underwent the VO2max test, and the exhaustive treadmill ran with biomechanical analysis at the beginning and the end. The two-way RMANOVA was used to assess differences between the groups and the phase of the run. A paired t-test was used for post-hoc analysis in case of significant interaction effect. Kinetic results showed significant group effect for ankle plantarflexion moment and hip external rotation moment (end-phase: both greater in MT group). Kinematic results showed significant group×phase interaction for ankle dorsiflexion angle (end-phase: greater in MT group) at initial contact (IC), peak knee flexion angle (end-phase: greater in MT group), and peak ankle eversion angle during the stance phase (end-phase: greater in HT group). Additionally, a group effect was found for knee flexion angle at IC (end-phase: greater in HT group). This study suggests that HT healthy NRFP runners may have less potential for increased biomechanical risk of AT overload during an exhaustive run.

INTRODUCTION: The E3 ubiquitin ligase Cbl-b is a novel target in immune-oncology, with critical roles in regulating T-cell activation and signaling pathways. By facilitating the ubiquitination and degradation of key signaling proteins, Cbl-b modulates immune responses, maintaining immune homeostasis and preventing unwarranted T-cell proliferation. The therapeutic potential of Cbl-b as a cancer immunotherapy target is underscored by its contribution to an immunosuppressive tumor microenvironment, with efforts currently underway to develop small-molecule inhibitors. AREAS COVERED: We reviewed the small molecules, and antibody-drug conjugates targeting Cbl-b from 2018 to 2024. The patents were gathered through publicly available databases and analyzed with in-house developed cheminformatic workflow, described within the manuscript. EXPERT OPINION: Targeting Cbl-b presents a promising approach in immuno-oncology, offering a novel pathway to potentiate the immune system's ability to combat cancer beyond PDL1/PD1 inhibition. The development and clinical advancement of Cbl-b inhibitors, as evidenced by the ongoing trials, mark a significant step toward harnessing this target for therapeutic benefits. Overall, the strategic inhibition of Cbl-b holds substantial promise for improving cancer immunotherapy outcomes, heralding a new era in the fight against cancer.

BACKGROUND: Skeletal muscle alterations are associated with higher mortality and morbidity in patients with liver cirrhosis. Assessing these changes seems to be a promising method for identifying patients at a high risk of poor outcomes following liver transplantation (LT). This is particularly important given the current global shortage of organ donors. However, evidence of the impact of these alterations on the prognosis of patients undergoing LT is inconclusive. The aim of our prospective study was to evaluate the impact of skeletal muscle changes, reflected in sarcopenia, myosteatosis and metabolic changes in the calf muscles, on perioperative outcomes and long-term survival after LT. We also sought to determine the posttransplant evolution of the resting muscle metabolism. METHODS: We examined 134 adult LT candidates. Of these, 105 underwent LT. Sarcopenia and myosteatosis were diagnosed by measuring the skeletal muscle index and mean psoas muscle radiation attenuation, respectively, which were obtained from computed tomography (CT) scans taken during pretransplant assessment. Additionally, patients underwent 31P MR spectroscopy (MRS) of the calf muscles at rest before LT and 6, 12 and 24 months thereafter. The median follow-up was 6 years. RESULTS: Patients with abnormal 31P MRS results and CT-diagnosed myosteatosis prior to LT had significantly worse long-term survival after LT (hazard ratio (HR), 3.36; 95% confidence interval (CI), 1.48-7.60; p = 0.0021 and HR, 2.58; 95% CI, 1.06-6.29; p = 0.03, respectively). Multivariable analysis showed that abnormal 31P MR spectra (HR, 3.40; 95% CI, 1.50-7.71; p = 0.003) were a better predictor of worse long-term survival after LT than myosteatosis (HR, 2.78; 95% CI, 1.14-6.78; p = 0.025). Patients with abnormal 31P MR spectra had higher blood loss during LT (p = 0.038), required a higher number of red blood cell transfusions (p = 0.006) and stayed longer in ICU (p = 0.041) and hospital (p = 0.007). Myosteatosis was associated with more revision surgeries following LT (p = 0.038) and a higher number of received red blood cell transfusion units (p = 0.002). Sarcopenia had no significant effect on posttransplant patient survival. An improvement in the resting metabolism of the calf muscles was observed at 12 and 24 months after LT. CONCLUSIONS: Abnormal 31P MRS results of calf muscles were superior to CT-based diagnosis of myosteatosis and sarcopenia in predicting perioperative complications and long-term survival after LT. Resting muscle metabolism normalized 1 year after LT in most recipients.

BACKGROUND: Orthotopic liver transplantation (OLT) has greatly improved short-term survival for end-stage liver disease. However, cardiovascular events (CVE) still pose a significant threat to long-term post-transplant health. Aim of this study is to assess the occurrence of long-term cardiovascular events and whether it relates to new-onset diabetes after liver transplantation (NODALT). METHODS: We conducted a multicentric retrospective analysis of adult OLT recipients with regular follow-up visits spanning from January 1995 to December 2020. Data collection included anamnestic, clinical, anthropometric, and laboratory data from two centers. NODALT was diagnosed following ADA guidelines. The primary outcome was incident CVE (a composite of fatal and non-fatal stroke and myocardial infarction). CVE occurrence was analyzed in relation to NODALT diagnosis, along with clinical characteristics associated with its development. RESULTS: Ninety-three eligible Caucasian patients, with a median age of 57.0 years (IQR: 49.0-62.0, 69.9% male), were enrolled. Over the median follow-up period of 100.5 months, 29 patients (31.2%) developed NODALT, and 14 patients (15.1%) developed any CVE, with 9 being in the NODALT group. A significant association between NODALT and cardiovascular complications was confirmed by both generalized estimating equation (OR 5.31; 95% CI 1.59-17.72, p = 0.006) and Kaplan-Meier analysis (log-rank = 0.046). Metabolic syndrome and impaired fasting glucose were identified as baseline risk factors for the incident NODALT (OR 5.75; 95% CI 1.44-22.92, p = 0.013 and OR 7.29; 95% CI 1.46-36.41, p = 0.015, respectively). CONCLUSIONS: Post-OLT cardiovascular events are less frequent than previously reported but are notably linked to NODALT, highlighting the interplay between metabolic syndrome and impaired fasting glucose.

Cancer and its treatment may lead to kidney injury and the need for kidney replacement therapy (KRT). We identified 287 pediatric KRT patients with a history of malignancy from the European Society for Paediatric Nephrology/European Renal Association Registry. Of these, 197 had cancer as a primary cause of KRT (group 1) and 90 had a malignancy diagnosis before KRT (group 2). Two matched controls without malignancy were randomly selected for each patient. Data were complemented with a questionnaire. Median time to kidney transplantation (KT) from KRT initiation was 2.4 (IQR: 1.5-4.7), 1.5 (IQR: 0.4-3.3), 3.6 (IQR: 1.3 to Q3 not reached), and 1.1 (IQR: 0.3-3.6) years for group 1, their controls, group 2, and their controls, respectively. Overall 10-year mortality for those on KRT was higher among cancer patients vs controls in group 1: 16% vs 9% (adjusted hazard ratio 2.02, 95% CI: 1.21-3.37) and in group 2: 23% vs 14% (adjusted hazard ratio 2.32, 95% CI: 1.11-4.85). In contrast, 10-year patient survival after the first KT was comparable to controls (93% vs 96%; 100% vs 94%, in groups 1 and 2, respectively). In summary, childhood cancer survivors' KT was delayed, and their overall mortality when on KRT was increased, but once transplanted, their long-term outcome was similar to other KT recipients.

A standardized methodology for the ultrasound evaluation of the pelvic sidewall has not been proposed to date. Herein, a collaborative group of gynecologists and gynecological oncologists with extensive ultrasound experience presents a systematic methodology for the ultrasonographic evaluation of structures within the pelvic sidewall. Five categories of anatomical structures are described (muscles, vessels, lymph nodes, nerves and ureters). A step-by-step transvaginal ultrasound (or, when this is not feasible, transrectal ultrasound) approach is outlined for the evaluation of each anatomical landmark within these categories. Accurate assessment of the pelvic sidewall using a standardized approach improves the detection and diagnosis of non-gynecological pathologies that may mimic gynecological tumors, reducing the risk of unnecessary and even harmful intervention. Furthermore, it plays an important role in completing the staging of malignant gynecological conditions. Transvaginal or transrectal ultrasound therefore represents a viable alternative to magnetic resonance imaging in the preoperative evaluation of lesions affecting the pelvic sidewall, if performed by an expert sonographer. A series of videoclips showing normal and abnormal findings within each respective category illustrates how establishing a universally applicable approach for evaluating this crucial region will be helpful for assessing both benign and malignant conditions affecting the pelvic sidewall. © 2024 The Author(s).
