Acute myeloid leukemia (AML) is one of the most prevalent blood cancers, characterized by a dismal survival rate. This poor outcome is largely attributed to AML cells that persist despite treatment and eventually result in relapse. Relapse-initiating cells exhibit diverse resistance mechanisms, encompassing genetic factors and, more recently discovered, nongenetic factors such as metabolic adaptations. Leukemic stem cells (LSC) rely on mitochondrial metabolism for their survival, whereas hematopoietic stem cells primarily depend on glycolysis. Furthermore, following treatments such as cytarabine, a standard in AML treatment for over four decades, drug-persisting leukemic cells exhibit an enhanced reliance on mitochondrial metabolism. In this issue of Cancer Research, two studies investigated dependencies of AML cells on two respiratory substrates, α-ketoglutarate and lactate-derived pyruvate, that support mitochondrial oxidative phosphorylation (OXPHOS) following treatment with the imipridone ONC-213 and the BET inhibitor INCB054329, respectively. Targeting lactate utilization by interfering with monocarboxylate transporter 1 (MCT1 or SLC16A1) or lactate dehydrogenase effectively sensitized cells to BET inhibition in vitro and in vivo. In addition, ONC-213 affected αKGDH, a pivotal NADH-producing enzyme of the TCA cycle, to induce a mitochondrial stress response through ATF4 activation that diminished the expression of the antiapoptotic protein MCL1, consequently promoting apoptosis of AML cells. In summary, targeting these mitochondrial dependencies might be a promising strategy to kill therapy-naïve and treatment-resistant OXPHOS-reliant LSCs and to delay or prevent relapse.

BACKGROUND: When the SRY gene is present in a 46,XX fetus, some degree of testicular development is expected. Our laboratory performed prenatal genetic testing for a fetus that had screened positive for Y chromosome material by noninvasive prenatal screening (NIPS) but that had apparently typical female development by ultrasound imaging. The aim of this study was to determine the clinical relevance of the NIPS results.
METHODS: We analyzed fetal material obtained via amniocentesis procedure by G-banding, microarray, and fluorescence in situ hybridization (FISH). Optical genome mapping (OGM) was also performed.
RESULTS: G-band analysis revealed a normal 46,XX karyotype. Microarray and FISH analyses together detected an SRY+ gain of 5.7 Mb from terminal Yp that was translocated to terminal Xq, with a loss of 1.6 Mb from terminal Xq. The final karyotype was 46,X,der(X)t(X;Y)(q28;p11.2). Prenatal ultrasound and postnatal physical examination revealed apparently typical female genitalia. The Xq deletion encompassed a gene, IKBKG, that is sensitive to loss of function, suggesting that preferential inactivation of the derivative X chromosome allowed for typical female development. OGM software did not directly identify this translocation.
CONCLUSION: This case demonstrates how the SRY gene may be present in a 46,XX biological female without differences of sexual development.
PURPOSE: We set out to characterize psychogenic non-epileptic seizures (PNES) in individuals with either intellectual disability (ID) or borderline intellectual function (BIF) in comparison to those with normal cognitive function. We aimed to identify differences between the two groups to improve clinical management protocols.
METHODS: We conducted a retrospective, observational, single-center study. The medical records of individuals (aged ≥ 14 years) diagnosed with PNES, confirmed through video-electroencephalography (vEEG) at a specialized epilepsy center between January 2008 and December 2021, were reviewed. We restricted our study to individuals who underwent comprehensive neuropsychological evaluations. Furthermore, demographic, clinical, and neuropsychological data with potential prognostic indicators, alongside the reevaluation of vEEG recordings were studied. We compared two study groups based on intelligence quotient (IQ): individuals without ID (IQ≥85; n = 25) and those with either mild ID or BIF (n = 25).
RESULTS: No statistically significant clinical differences were observed between the two groups. Individuals with mild ID/BIF didn't show a longer diagnostic delay, and the prescription of inappropriate antiseizure medications (ASMs) was comparable in both cohorts. Most individuals with mild ID/BIF were treated with behavioral psychotherapeutic approaches with similar outcomes in both subgroups.
CONCLUSIONS: Individuals with mild ID/BIF and PNES don't differ in clinical management. Demographic and clinical data, as well as semiology, were comparable to those of individuals with normal cognitive function. Cognitive behavioral therapy (CBT) appears to be an effective treatment approach for individuals with and without mild ID/BIF. Further studies are needed to validate and ascertain their possible applicability in individuals with moderate/severe ID.
Bifunctional molecules and methods for their use in the production of binary complexes in a host are provided. The bifunctional molecule is a conjugate of a drug moiety and a presenter protein ligand. The molecular weight of the bifunctional molecule is preferably less than about 5000 daltons, and the drug moiety may have a molecular weight of from about 50 to 2000 daltons. The drug moiety and presenter protein ligand may be covalently linked directly or through a linking group. The drug moiety binds to a drug target such as a protein and the presenter protein ligand binds to a presenter protein that is not the drug target such as extracellular or intracellular protein. Presenter proteins include peptidyl prolyl isomerase (FKBP), Heat Shock Protein 90 (Hsp90), steroid hormone receptors, cytoskeletal proteins, albumin and vitamin receptors. When the presenter protein is FKBP, ligands include FK506, rapamycin and cyclosporin A which may have an introduced functional group such as hydroxyl, amino, carboxyl, aldehyde, carbonate, carbamate, azide, thiol or ester for attaching the drug moiety. In the methods of use, an effective amount of the bifunctional molecule is administered to the host. The bifunctional molecule binds to the presenter protein to produce a binary complex such that the drug exhibits at least one of improved affinity, specificity or selectivity as compared to the corresponding free drug. The methods and bifunctional molecules find use in a variety of therapeutic applications.
Participants will receive 4 weekly individual sessions of IR. The IR technique consists of imagining a negative memory or image as vividly as possible, and of transforming it into a positive one. An odorless diffuser will be presented while imagining the positive imagery generated during IR. During 4 weeks, patients of this group will practice IR at home, every day in bed and have the same odorless diffuser being diffused during the night.

No specific exercises or stress reduction techniques are prescribed and the patient will be counseled to continue their current level of activity, and will be given the information on exercise as outlined in the Cancer Care Ontario guidelines. Patients in the Usual Care arm will also be given the same Fitbit activity tracker as patients in the Prehabilitation arm in order to eliminate the activity tracker as an intervention itself and to be able to track the activity (steps) for comparison. Patients in the Usual Care arm will be required to wear their Fitbit activity tracker from the day of randomization to 90 days post-surgery. Patients will record their steps in the diary provided.
This is a nonrandomized (study drug is intentionally assigned), open-label (all people involved know the identity of the intervention), single-arm (one group of patients receiving the same treatment), multi-centered study of galantamine in patients with Alzheimer's disease (AD). Galantamine has been approved for treatment of mild to moderate dementia of AD. Galantamine is available as film-coated tablet in 68 countries including the United States and Europe, and is also available as oral syrup and extended-release capsule in 65 counties. In Japan, galantamine was approved in January 2011 and is available in three dosage forms of film-coated tablet, oral disintegrant tablet, and oral syrup. The target population is patients with mild to moderate dementia of Alzheimer's type (ie, Mini-Mental State Examination \[MMSE\] ranging from 10 to 22) who failed to benefit from donepezil. Patients must have diagnosis of probable AD according to the diagnostic criteria National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) study group. To ensure that at least 100 subjects complete the study, 125 subjects will be enrolled. The treatment group is to receive flexible dosing of 16 mg/day or 24 mg/day. Patients will receive the study treatment for 24 weeks in accordance with the dosing regimen specified in the protocol.
Receiving radiotherapy induces anxiety in at least 1/3 of patients who did not have a previously existing anxiety condition1. Female gender is a positive predictive factor for psychosocial decline during radiotherapy. One-fourth of patients disrupt their planned radiotherapy treatment course due to anxiety. Music therapy has demonstrated effectiveness in reducing anxiety when implemented in other medical settings including mechanical ventilation, burn debridement and venipuncture in pediatric patients. There have been some trials which have found a reduction in anxiety when pre-recorded music along with other relaxation techniques have been implemented during radiotherapy. This trial seeks to investigate the benefit of pre-recorded music alone in reducing anxiety experienced during the first radiotherapy treatment session in female cancer patients.

INTRODUCTION: Total knee arthroplasty (TKA) is a common surgical intervention to treat joint diseases. However, TKA is associated with significant blood loss. Tranexamic acid (TXA) has been used to reduce perioperative bleeding and postoperative blood transfusion. This study aims to explore the effectiveness and safety of intraosseous regional administration (IORA) of TXA in TKA and compare differences in perioperative blood loss between IORA of TXA, intravenous infusion of TXA, and combined IORA and intravenous infusion of TXA.
METHODS AND ANALYSIS: This randomised controlled trial will enrol 105 patients with osteoarthritis who meet the inclusion criteria for unilateral TKA. Patients were randomly divided into three groups using the random number table method. Group A received 1.0 g of TXA via IORA, group B received 1.0 g of TXA via intravenous infusion 15 min prior to the tourniquet release, and group C received both IORA of 1.0 g of TXA and intravenous infusion of 1.0 g of TXA. The primary outcome measure is perioperative total blood loss. Secondary outcomes include bleeding events, venous thromboembolism events, inflammation reactions, other complications and knee function assessments.
ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of Peking Union Medical College Hospital and registered in the Chinese Clinical Trial Registry. Informed consent will be obtained from all the patients before enrolment. The trial will be conducted in accordance with the principles of the Declaration of Helsinki and the International Conference on Harmonization Good Clinical Practice guidelines. The results of this study will be disseminated through peer-reviewed publications, conference presentations and social media platforms. The findings will provide valuable insights into the use of IORA of TXA in TKA and may lead to the development of new strategies for perioperative blood management in joint replacement surgery.
TRIAL REGISTRATION NUMBER: The Ethics Committee of Peking Union Medical College Hospital (approval number: K2371); Chinese Clinical Trial Registry (trial registration number: ChiCTR2200066293).
Hepatectomies are characterized by an elevated risk of severe hemorrhage. The high vascular supply of the liver has historically troubled surgeons who resolved to techniques to control excessive blood loss. The Pringle Maneuver commonly employed in liver surgery is a temporary method to occlude the vascular supply of the liver. As a result, ischemia is developed and a pathophysiologic cascade is initiated. Upon the resolution of ischemia, reperfusion occurs which is linked to further damage and the ischemia-reperfusion injury is developed. Ischemia and reperfusion lead to activation of the innate immune response, which interacts with the adaptive immune response. Result of this interaction is the production of inflammatory cytokines, chemokines, complement products, and the recruitment of neutrophils to the site of injury. Previous studies have shown that animal's livers suffered from ischemia-reperfusion injury had increased neutrophil infiltration and pharmacological agents attenuating neutrophil's activity improved hepatic Ischemia-Reperfusion Injury (IRI). Preconditioning refers to the exposure of an organ to short intervals of ischemia which has been shown to mitigate the aforementioned ischemia-reperfusion injury. Preconditioning can be pharmacological and volatile anesthetics have been successfully used in preconditioning models. Sevoflurane have been proved beneficial for a series of hepatectomies in limiting transaminase levels postoperatively. However, sevoflurane by virtue can be hepatotoxic through Compound A production, elevated free calcium and reactive oxide species activation. On the other hand, desflurane undergoes minimum liver metabolism. In liver ischemia-reperfusion models, desflurane preconditioning led to decreased cell death and inflammatory cytokines inhibition.

The goal of the investigator's study was to investigate the effect of desflurane preconditioning in patients undergoing elective hepatectomy of at least two segments. Patients were randomized 1:1 to receive pharmacological preconditioning (Desflurane Group, Group D) or not (Control Group, Group C). The surgeon and the Intensive Care Unit were blinded as to the intervention. Anesthetic management was the same for all patients. For GroupD thirty minutes before the initiation of ischemia desflurane was delivered and propofol was stopped for the same interval.
Pathogenic variants in the FAN1 gene lead to a systemic disease with karyomegalic interstitial nephritis (KIN) at the forefront clinically. The phenotypic-genotypic features of a FAN1 mutation-related disease involving five members of a Hungarian Caucasian family are presented. Each had adult-onset chronic kidney disease of unknown cause treated with renal replacement therapy and elevated liver enzymes. Short stature, emaciation, latte-colored skin, freckles, and a hawk-like nose in four patients, a limited intellect in two patients, and chronic restrictive lung disease in one patient completed the phenotype. Severe infections occurred in four patients. All five patients had ceased. Four patients underwent autopsy. KIN and extrarenal karyomegaly were observed histologically; the livers showed no specific abnormality. The genotyping using formalin-fixed tissue samples detected a hitherto undescribed homozygous FAN1 mutation (c.1673_1674insT/p.Met558lfs*4; exon 5) in three of these patients and a heterozygous FAN1 mutation in one patient. The reason for the heterozygosity is discussed. In addition, 56 family members consented to the screening for FAN1 mutation from which 17 individuals proved to be heterozygous carriers; a blood chemistry evaluation of their kidney and liver function did not find any abnormality. The clinical presentation of FAN1-related disease was multifaceted, and not yet described manifestations were observed besides kidney and liver disease. Mutation in this gene should be suspected in adults with small kidneys of unknown cause, elevated liver enzymes, and recurrent infections, even without a family history.
The prevalence of hypertension is very high in older adults, and a major factor in hypertension is salt sensitivity of blood pressure (BP) and elevated sympathetic nerve activity (SNA). However, we know very little about how the human brain 'senses' sodium, and what molecular mechanisms are involved. Rodent studies have identified specialized sodium chloride (NaCl)-sensing neurons in the circumventricular organs (CVOs), which mediate NaCl-induced changes in SNA, arginine vasopressin (AVP), and BP. Recent data suggest the Na-K- 2Cl co-transporter (NKCC2) is not kidney specific but is also expressed in brain regions that regulate whole body NaCl and water homeostasis. In addition, NKCC2 is accessible by drugs in the circulation since the CVOs lack a complete blood brain barrier. The objective of this R21 is to identify key NaCl-sensing regions of the brain in older adults and determine if NKCC2 mediates the neurohumoral response to acute hypernatremia. We seek to translate the prior rodent findings to humans by assessing neuronal activation (using blood oxygen level dependent functional magnetic resonance imaging, BOLD fMRI) as well as thirst, AVP, SNA and BP during an acute hypernatremic stimulus, with and without an NKCC2 antagonist (furosemide). This will enable us to assess the role of NKCC2 in NaCl sensing. The overall hypothesis is that acute hypernatremia will elicit detectable changes in the BOLD fMRI signal and increase thirst, AVP, SNA, and BP largely through NKCC2 in healthy older adults. Accordingly, the first specific aim is to identify the areas of the human brain that respond to acute hypernatremia and determine the role of NKCC2 in central NaCl- sensing. Acute hypernatremia will be induced with a 30-minute infusion of 3% NaCl delivered intravenously. Brain activity during the hypertonic saline infusion will be measured in regions such as the organum vasculosum laminae terminalis, subfornical organ, anterior cingulate cortex, hypothalamus, and insular cortex. The second specific aim is to determine the effect of acute hypernatremia on thirst, AVP, SNA, and BP, and determine the role of NKCC2 in mediating these responses. Salt sensitivity of BP will be individually assessed and comparisons will be made between those with a salt resistant and salt sensitive phenotype; we anticipate that acute hypernatremia will elicit changes in the BOLD fMRI signal and SNA \& AVP in all subjects, but the responses will be greater in those who are classified as salt sensitive. This would represent the first trial in healthy human subjects to identify a putative brain NaCl-sensing co-transporter, and we think the scope and innovative approaches are ideal for the R21 funding mechanism. Older adults are prone to hypertension, so it is critically important to understand how normotensive older adults centrally sense sodium, to provide a needed foundation for exploring the mechanistic underpinning of salt sensitive hypertension.
