Embryonic neurogenesis can be defined as a period of prenatal development during which divisions of neural stem and progenitor cells give rise to neurons. In the central nervous system of most mammals, including humans, the majority of neocortical neurogenesis occurs before birth. It is a highly spatiotemporally organized process whose perturbations lead to cortical malformations and dysfunctions underlying neurological and psychiatric pathologies, and in which oxygen availability plays a critical role. In case of deprived oxygen conditions, known as hypoxia, the hypoxia-inducible factor (HIF) signaling pathway is activated, resulting in the selective expression of a group of genes that regulate homeostatic adaptations, including cell differentiation and survival, metabolism and angiogenesis. While a physiological degree of hypoxia is essential for proper brain development, imbalanced oxygen levels can adversely affect this process, as observed in common obstetrical pathologies such as prematurity. This review comprehensively explores and discusses the current body of knowledge regarding the role of hypoxia and the HIF pathway in embryonic neurogenesis of the mammalian cortex. Additionally, it highlights existing gaps in our understanding, presents unanswered questions, and provides avenues for future research.

PURPOSE: To determine the factors influencing the likelihood of biochemical pregnancy loss (BPL) after transfer of a euploid embryo from preimplantation genetic testing for aneuploidy (PGT-A) cycles.
METHODS: The study employed an observational, retrospective cohort design, encompassing 6020 embryos from 2879 PGT-A cycles conducted between February 2013 and September 2021. Trophectoderm biopsies in day 5 (D5) or day 6 (D6) blastocysts were analyzed by next generation sequencing (NGS). Only single embryo transfers (SET) were considered, totaling 1161 transfers. Of these, 49.9% resulted in positive pregnancy tests, with 18.3% experiencing BPL. To establish a predictive model for BPL, both classical statistical methods and five different supervised classification machine learning algorithms were used. A total of forty-seven factors were incorporated as predictor variables in the machine learning models.
RESULTS: Throughout the optimization process for each model, various performance metrics were computed. Random Forest model emerged as the best model, boasting the highest area under the ROC curve (AUC) value of 0.913, alongside an accuracy of 0.830, positive predictive value of 0.857, and negative predictive value of 0.807. For the selected model, SHAP (SHapley Additive exPlanations) values were determined for each of the variables to establish which had the best predictive ability. Notably, variables pertaining to embryo biopsy demonstrated the greatest predictive capacity, followed by factors associated with ovarian stimulation (COS), maternal age, and paternal age.
CONCLUSIONS: The Random Forest model had a higher predictive power for identifying BPL occurrences in PGT-A cycles. Specifically, variables associated with the embryo biopsy procedure (biopsy day, number of biopsied embryos, and number of biopsied cells) and ovarian stimulation (number of oocytes retrieved and duration of stimulation), exhibited the strongest predictive power.
The present invention concerns methods comprising co-administration of pegfilgrastim and romiplostim for treatment of diseases and conditions characterized by low neutrophil levels (neutropenia) and/or low platelet levels (thrombocytopenia). The present invention concerns an enhanced effect on neutrophil levels and on platelet levels resulting from co-administration of pegfilgrastim and romiplostim. The present invention further concerns a method of treating a patient who has been exposed to radiation, which comprises administering romiplostim at a dose of about 1 to about 10 g/kg. The invention further concerns such methods wherein a single dose of romiplostim is administered to the patient and wherein romiplostim is administered about 24 hours or less after the radiation exposure. The invention further concerns treatment with romiplostim and pegfilgrastim for radiation exposure. Such methods relate to treatment of acute radiation syndrome and treatment to counteract the effects of radiation therapy and other sources of radiation exposure.
Long-term treatment with bisphosphonates is accompanied by an increased risk of medication-related osteonecrosis of the jaw (MRONJ). Currently, no clinically useful biomarkers for the predictive diagnosis of MRONJ are available. To investigate the potential key proteins involved in the pathogenesis of MRONJ, a proteomic LC-MS/MS analysis of saliva was performed. Differentially expressed proteins (DEPs) were analyzed using BiNGO, ClueGO, cytoHubba, MCODE, KEGG, and ReactomeFI software packages using Cytoscape platforms. In total, 1545 DEPs were identified, including 43 up- and 11 down-regulated with a 1.5-fold cut-off value and adj. p-value < 0.05. The analysis provided a panel of hub genes, including APOA2, APOB, APOC2, APOC3, APOE, APOM, C4B, C4BPA, C9, FGG, GC, HP, HRG, LPA, SAA2-SAA4, and SERPIND1. The most prevalent terms in GO of the biological process were macromolecular complex remodeling, protein-lipid complex remodeling, and plasma lipoprotein particle remodeling. DEPs were mainly involved in signaling pathways associated with lipoproteins, the innate immune system, complement, and coagulation cascades. The current investigation advanced our knowledge of the molecular mechanisms underlying MRONJ. In particular, the research identified the principal salivary proteins that are implicated in the onset and progression of this condition.
Studies have shown that the majority of patients undergoing selective surgery experience different levels of anxiety. The degree of anxiety is influenced by factors such as patient demographic characteristics, type of surgery, previous experiences with operational procedures, willingness to undergo the proposed intervention, perceived rapport with hospital personnel and personal stress threshold. This anxiety has been shown to be correlated with acute postoperative pain and chronic postsurgical pain, which leads to an increased use of postoperative analgesic, slow recovery, and other maladaptation behaviours in paediatric patient like eating disorders. The link between greater preoperative anxiety and the risk for developing chronic postsurgical pain has been documented in a variety of surgical procedures, including elective abdominal hysterectomy, radical mastectomy, breast cancer surgery, and arthroscopic knee surgery. While pharmacological interventions such as opioid-based analgesic are available, other methods to manage anxiety and distract patients from stressors - such as music, television, and virtual reality - have become more popular in the recent years due to their safety, low cost and effectiveness in improving overall patient experience and outcome.

Virtual reality (VR) is a promising new technology that offers opportunities to modulate pain experience and cognition. Patients received VR treatment reported a reduction in pain and anxiety, faster wound healing, decreased chronic pain intensity and other neurorehabilitation improvements. The recent advent of inexpensive consumer VR system has also made VR more accessible to the mass, especially those by Samsung available locally. In SingHealth, VR has been used in neurosurgery for individualized surgery planning for patients with brain tumours, vascular malfunction and skull based tumours. However, there has been little done to investigate the effectiveness of VR during the preoperative period especially in local setting. Therefore, the investigators will investigate the feasibility and practicability of employing VR in anxiety and pain management in patients undergoing same day admission or day surgery. The proposed intervention may not only be implemented in the preoperative environment but also be in other settings such as before diagnostic screening or minor treatments done during inpatient stay or outpatient visit. The use of VR is suitable for those who are preparing for procedures in clinic or ward as an alternative anxiety management without prolonging the preparation time.

Unfractionated heparin is the most common anticoagulant used during percutaneous coronary intervention. Practice guidelines recommend an initial weight-based heparin bolus dose between 70 and 100 U/kg to achieve target activated clotting time (ACT) of 250-300 seconds. The impact of severe obesity on weight-based heparin dosing is not well studied. We performed a retrospective analysis of 424 patients undergoing percutaneous coronary intervention who received heparin for anticoagulation. We collected detailed data on cumulative heparin administration and measured ACT values in this cohort. We performed separate analyses to identify clinical predictors that may affect dose-response curves. There was significant variability in dosing with mean dose of 103.9 ± 32-U/kg heparin administered to achieve target ACT ≥ 250 seconds. Women received higher initial heparin doses when adjusted for weight than men (97.6 ± 31 vs. 89 ± 28 U/kg, P = 0.004), and only 49% of patients achieved ACT ≥ 250 s with the initial recommended heparin bolus dose (70-100 U/kg). Lower heparin dose (U/kg) was required in obese patients to achieve target ACT. In multivariate linear regression analysis with ACT as dependent variable, after inclusion of weight-based dosing for heparin, body mass index was the only significant covariate. In conclusion, there is significant variability in the therapeutic effect of heparin, with a lower weight-adjusted heparin dose required in obese patients.
Fishes are hosts for many microorganisms that provide them with beneficial effects on growth, immune system development, nutrition and protection against pathogens. In order to avoid spreading of infectious diseases in aquaculture, prevention includes vaccinations and routine disinfection of eggs and equipment, while curative treatments consist in the administration of antibiotics. Vaccination processes can stress the fish and require substantial farmer's investment. Additionally, disinfection and antibiotics are not specific, and while they may be effective in the short term, they have major drawbacks in the long term. Indeed, they eliminate beneficial bacteria which are useful for the host and promote the raising of antibiotic resistance in beneficial, commensal but also in pathogenic bacterial strains. Numerous publications highlight the importance that plays the diversified microbial community colonizing fish (i.e., microbiota) in the development, health and ultimately survival of their host. This review targets the current knowledge on the bidirectional communication between the microbiota and the fish immune system during fish development. It explores the extent of this mutualistic relationship: on one hand, the effect that microbes exert on the immune system ontogeny of fishes, and on the other hand, the impact of critical steps in immune system development on the microbial recruitment and succession throughout their life. We will first describe the immune system and its ontogeny and gene expression steps in the immune system development of fishes. Secondly, the plurality of the microbiotas (depending on host organism, organ, and development stage) will be reviewed. Then, a description of the constant interactions between microbiota and immune system throughout the fish's life stages will be discussed. Healthy microbiotas allow immune system maturation and modulation of inflammation, both of which contribute to immune homeostasis. Thus, immune equilibrium is closely linked to microbiota stability and to the stages of microbial community succession during the host development. We will provide examples from several fish species and describe more extensively the mechanisms occurring in zebrafish model because immune system ontogeny is much more finely described for this species, thanks to the many existing zebrafish mutants which allow more precise investigations. We will conclude on how the conceptual framework associated to the research on the immune system will benefit from considering the relations between microbiota and immune system maturation. More precisely, the development of active tolerance of the microbiota from the earliest stages of life enables the sustainable establishment of a complex healthy microbial community in the adult host. Establishing a balanced host-microbiota interaction avoids triggering deleterious inflammation, and maintains immunological and microbiological homeostasis.

Comprehensive resources exist on how to plan a systematic review and meta-analysis. The objective of this article is to provide guidance to authors preparing their systematic review protocol in the fields of regional anesthesia and pain medicine. The focus is on systematic reviews of health care interventions, with or without an aggregate data meta-analysis. We describe and discuss elements of the systematic review methodology that review authors should prespecify, plan, and document in their protocol before commencing the review. Importantly, authors should explain their rationale for planning their systematic review and describe the PICO framework-participants (P), interventions (I), comparators (C), outcomes (O)-and related elements central to constructing their clinical question, framing an informative review title, determining the scope of the review, designing the search strategy, specifying the eligibility criteria, and identifying potential sources of heterogeneity. We highlight the importance of authors defining and prioritizing the primary outcome, defining eligibility criteria for selecting studies, and documenting sources of information and search strategies. The review protocol should also document methods used to evaluate risk of bias, quality (certainty) of the evidence, and heterogeneity of results. Furthermore, the authors should describe their plans for managing key data elements, the statistical construct used to estimate the intervention effect, methods of evidence synthesis and meta-analysis, and conditions when meta-analysis may not be possible, including the provision of practical solutions. Authors should provide enough detail in their protocol so that the readers could conduct the study themselves.

BACKGROUND: Pectoral nerve (PECs) blocks are established regional anesthesia techniques that can provide analgesia to the anterior chest wall. Although commonly performed preoperatively by anesthesiologists, the feasibility of electrophysiologist-performed PECs blocks from within cardiac implantable electronic device (CIED) pockets at the time of implantation has not been established. The objective of this study is to assess the feasibility of routine PECs blocks performed by the electrophysiologist from within the exposed device pocket at the time of CIED procedures.
METHODS: Patients undergoing CIED procedures underwent a PECs I block (15 cc of 1% lidocaine/0.25% bupivacaine) injected between the pectoralis major and minor muscles guided by ultrasound placed in the device pocket, or PECs II block, which included a second injection (15 cc) between pectoralis minor and serratus anterior muscles. Postoperatively, pain was assessed on a numeric scale (0-10) at 1, 2, 4, and 24 h, and 2 weeks after the procedure.
RESULTS: Among 20 patients (age 65 ± 16 years, 70% male, 55% with history of chronic pain), PECs I (75%) and PECs II (25%) blocks were performed. The procedures were de novo implantation (n = 17) or device revision (n = 3). The average pain score in the first 4 h was 0.4 ± 0.8 and 0.3 ± 0.6 at 24 h after the procedure. During the 24-h postoperative period, 4 patients received opioids. Two patients were discharged with opioids for pain unrelated to the procedure.
CONCLUSIONS: Intraoperative PECs blocks can be feasibly performed from within an exposed pocket at the time of CIED procedures with minimal postoperative pain.
Apricitabine is a new NRTI in development for treatment of drug resistant HIV. Tipranavir is a recently licensed protease inhibitor for treatment of drug resistant HIV. Tipranavir affects the plasma concentration of some other drugs when they are used together with tipranavir. This study will examine whether the pharmacokinetics of apricitabine are changed when it is dosed together with tipranavir compared to apricitabine alone. Also, the pharmacokinetics of tipranavir will be examined at steady state when it is dosed alone and when it is dosed together with apricitabine. Information on the safety and tolerability of the two drugs when dosed together will also be obtained.
The aim of this clinical study is to evaluate the effect of dental post application on postoperative pain intensity level in patients with asymptomatic teeth after a single-appointment root canal treatment. A total of one hundred patients with asymptomatic teeth and with no contradictory medical history who are indicated for non-surgical root canal treatment and application of a dental post at the Endodontic Clinic, Faculty of Dentistry, Istanbul Medipol University, between April and December of 2019 will be included. All of the patients will be recruited from the Istanbul Medipol University Dental Clinics in Istanbul. the patients will be divided in two groups (n=50). Consent will be obtained from all study participants before the treatment. After the root canal treatments are completed in single-visit, in the first groups dental posts will be applied immediately at the same visit and patients will be appointed for pain assessment. In group 2 after the root canal treatment a temporary filling be applied in the access cavity and patients will be appointed for pain assessment. Dental posts will be applied after the pain assessment is completed at the end of 1 week. All treatments will be performed by one endodontist. Postoperative pain intensity will be assessed at 24, 48, and 72 h; 7 days; after the treatment. The teeth will be examined according to postoperative pain intensity levels,

PURPOSE: Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) combined with endocrine therapy have demonstrated significant clinical benefits in progression-free and overall survival. This study investigates the outcomes associated with two kinds of CDK4/6i in patients with hormone receptor (HR)-positive metastatic and relapsed breast cancer to inform real-world evidence of treatment strategies.
METHODS: This retrospective study included 340 Taiwanese patients with HR-positive advanced breast cancer from the Taipei Veterans General Hospital, between 2018 and 2023. We analyzed patient characteristics, treatment strategies and outcomes associated with two CDK4/6i. The efficacy of patients who experienced economic burden and interrupted CDK4/6i treatment after 2 years of National Health Insurance (NHI) reimbursement was also investigated.
RESULTS: Patients receiving ribociclib and palbociclib showed no significant differences in age, histology, body mass index(BMI), or pathologic status. The distribution of disease status and endocrine therapy partners was comparable between the two groups. Dose reduction was similar, while patients with palbociclib tended to discontinue CDK4/6i usage, and those with ribociclib tended to switch to the other CDK4/6i or endocrine partners. There was no significant difference in progression-free survival (PFS) between the two CDK4/6i in the first-line setting. Adverse prognostic factors were increasing HER2 IHC score, higher Ki-67 levels, visceral and liver metastasis, prior chemotherapy, and endocrine therapy resistance, while higher BMI, bone-only metastasis, and letrozole treatment were associated with a lower risk of progression. The limited follow-up time in our study was insufficient to assess the outcomes of patients treated with interrupted CDK4/6i for up to two years under the NHI reimbursement policy.
CONCLUSION: Treatment outcomes between the two types of CDK4/6i did not differ significantly, indicating the safety and efficacy of CDK4/6i for the Asian population. Ribociclib and palbociclib showed similar efficacy in PFS in the real-world setting.
Sickle cell disease (SCD) is canonically characterized by reduced red blood cell (RBC) deformability, leading to microvascular obstruction and inflammation. Although the biophysical properties of sickle RBCs are known to influence SCD vasculopathy, the contribution of poor RBC deformability to endothelial dysfunction has yet to be fully explored. Leveraging interrelated in vitro and in silico approaches, we introduce a new paradigm of SCD vasculopathy in which poorly deformable sickle RBCs directly cause endothelial dysfunction via mechanotransduction, during which endothelial cells sense and pathophysiologically respond to aberrant physical forces independently of microvascular obstruction, adhesion, or hemolysis. We demonstrate that perfusion of sickle RBCs or pharmacologically-dehydrated healthy RBCs into small venule-sized "endothelialized" microfluidics leads to pathologic physical interactions with endothelial cells that directly induce inflammatory pathways. Using a combination of computational simulations and large venule-sized endothelialized microfluidics, we observed that perfusion of heterogeneous sickle RBC subpopulations with varying deformability, as well as suspensions of dehydrated normal RBCs admixed with normal RBCs, leads to aberrant margination of the less-deformable RBC subpopulations toward the vessel walls, causing localized, increased shear stress. Increased wall stress is dependent on the degree of subpopulation heterogeneity and oxygen tension and leads to inflammatory endothelial gene expression via mechanotransductive pathways. Our multifaceted approach demonstrates that the presence of sickle RBCs with reduced deformability leads directly to pathological physical (ie, direct collisions and/or compressive forces) and shear-mediated interactions with endothelial cells and induces an inflammatory response, thereby elucidating the ubiquity of vascular dysfunction in SCD.
