Manzamine A: A Promising Marine-Derived Cancer Therapeutic for Multi-targeted Interactions with E2F8, SIX1, AR, GSK-3β, and V-ATPase - A Systematic Review.

Manzamine A, a natural compound derived from various sponge genera, features a β-carboline structure and exhibits a range of biological activities, including anti-inflammatory and antimalarial effects. Its potential as an anticancer agent has been explored in several tumor models, both in vitro and in vivo, showing effects through mechanisms such as cytotoxicity, regulation of the cell cycle, inhibition of cell migration, epithelial-to-mesenchymal transition (EMT), autophagy, and apoptosis through multi-target interactions of E2F transcriptional factors, ribosomal S6 kinases, androgen receptor (AR), SIX1, GSK-3β, V-ATPase, and p53/p21/p27 cascades. This systematic review evaluates existing literature on the potential application of this marine alkaloid as a novel cancer therapy, highlighting its promising ability to inhibit cancer cell growth while causing minimal side effects.

The risk of donor-acquired allergy in solid organ transplant recipients: a systematic review.

Background: Donor acquired allergy (DAA) occurs when donors transfer their allergies to recipients through solid organ transplant (SOT). However, the risk of DAA in recipients of organs from allergic donors has not been systematically characterized.

Objective: We sought to synthesize the available evidence on the risk of DAA in SOT recipients.

Planetary Health Diet Index in relation to mortality in a prospective cohort study of U.S. Black females.

Background: To improve both human health and the health of our planet, the EAT-Lancet Commission proposed the planetary health diet (PHD).

Objective: We aimed to evaluate associations of PHD with all-cause, cardiovascular disease (CVD), and cancer-specific mortality among U.S.

First evidence of human infection by the kinetoplastid flagellate Dimastigella trypaniformis in a patient with urinary tract infection.

We present a case of an 88-year-old man with symptoms consistent with a urinary tract infection, whose diagnostic workup uncovered a previously unrecognized motile flagellated protozoan. Molecular identification confirmed the organism as Dimastigella trypaniformis, a free-living kinetoplastid from the Rhynchomonadidae family. Known only from soil samples in Scotland and termite gut contents in Australia and Germany, Dimastigella trypaniformis has not been previously reported to infect vertebrate hosts.

Rotating Hinge Revision Total Knee Arthroplasty With and Without Porous Cone Adjunct Fixation.

Introduction: As the number of revision total knee arthroplasties (rTKA) continues to rise, there is increasing interest in the use of contemporary rotating hinge prostheses. These devices often incorporate porous cones to fill bone defects and enhance long-term fixation. This study evaluated the clinical and functional outcomes and survivorship in rTKA patients utilizing a rotating hinge prosthesis with flexible titanium (FT) cones, porous tantalum (PT) cones, or no cones.

Objective: To assess longitudinal protein and metabolite composition in AD skin during dupilumab treatment.

Methods: Skin tape strip (STS) were collected from lesional/non-lesional skin of 20 AD patients during 16-week dupilumab treatment and from 20 healthy volunteers (HV) followed for 16-weeks.

Long Term Results of a Comparative Study of Percutaneous and Surgically Created Proximal Forearm Arteriovenous Fistulae.

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.

Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.

Racial and ethnic enrollment disparities in clinical trials leading to FDA approvals for gynecologic malignancies.

Background: Black women and other minorities have higher age adjusted incidence risk for cervical and endometrial cancer than White women. However, the extent of racial and ethnic disparities in clinical trial enrollment among studies performed mainly in North America and Europe for gynecologic malignancy is unknown.

Objective: This study analyzed enrollment rates by race/ethnicity in trials that led to Food and Drug Administration (FDA) approvals for gynecological cancers from 2010 to 2024.

TARGETING LUNG HEME IRON BY AEROSOL HEMOPEXIN ADMINSTRATION IN SICKLE CELL DISEASE PULMONARY HYPERTENSION.

Lung tissue from human patients and murine models of sickle cell disease pulmonary hypertension (SCD-PH) show perivascular regions with excessive iron accumulation. The iron accumulation arises from chronic hemolysis and extravasation of hemoglobin (Hb) into the lung adventitial spaces, where it is linked to nitric oxide depletion, oxidative stress, inflammation, and tissue hypoxia, which collectively drive SCD-PH. Here, we tested the hypothesis that intrapulmonary delivery of hemopexin (Hpx) to the deep lung is effective at scavenging heme-iron and attenuating the progression of SCD-PH.

Acute angiotensin receptor blockade and mnemonic discrimination in healthy participants.

Background: The renin angiotensin system (RAS) is implicated in various cognitive processes relevant to anxiety. However, the role of the RAS in pattern separation, a hippocampal memory mechanism that enables discrete encoding of similar stimuli, is unclear. Given the proposed role of this mechanism in overgeneralization and the maintenance of anxiety, we explored the influence of the RAS on mnemonic discrimination i.

Association between prenatal depressive symptoms and receipt of recommended maternal and infant care postpartum.

Background: Maternal mental health can impact health care access and utilization for both the birthing parent and infant. We examined the association between prenatal depressive symptoms (episodic and chronic) and receipt of the postpartum 6-week visit and infant vaccinations in the first year postpartum.

Methods: Postpartum individuals (N = 672) who attended Expect With Me group prenatal care in Nashville, Tennessee and Detroit, Michigan completed surveys during the second and third trimesters of pregnancy, as well as 6- and 12- months postpartum.

Risk Factors for Postoperative Infection in Patients After Pilon Fracture Fixation.

The combination of high energy fractures, extensive soft tissue trauma, and high infection rates in pilon fractures of the distal tibia have long challenged surgeons. Despite the ample evidence, there is no consensus regarding the factors that may influence postoperative infections following surgical management of these fractures. This study aimed to investigate the risk factors for postoperative infections in patients undergoing surgical management for pilon fractures.

Six-month safety and efficacy outcomes from the randomized-controlled arm of the WRAPSODY Arteriovenous Access Efficacy (WAVE) trial.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Intravenous Tranexamic Acid Does Not Improve Visual Field Clarity During Hip Arthroscopy: A Double-Blind, Randomized, Placebo-Controlled Trial.

Purpose: To determine the effectiveness of administering intravenous (IV) tranexamic acid (TXA) on altering visual field clarity (VFC) during arthroscopic hip preservation surgery for patients with femoroacetabular impingement syndrome (FAIS).

Methods: This randomized, double-blind, parallel-design trial was conducted over a seven-month period between October 2023 and May 2024 at a single tertiary musculoskeletal hospital. Inclusion criteria included consecutive patients that were diagnosed with FAIS through clinical history, physical exam and advanced imaging and indicated for hip arthroscopy after having failed conservative management.

Contemporary Approach to the Diagnosis and Classification of Intestinal T-cell Lymphomas.

We provide an overview of recent advances in the diagnosis and classification of intestinal T- and NK-cell lymphomas and lymphoproliferative disorders that primarily involve the gastrointestinal (GI) tract. It should be mentioned that systemic T- and NK-cell lymphomas can present initially in the GI tract but are not the focus of this review. Here, we focus on the clinical and pathologic findings of enteropathy-associated T-cell lymphoma, monomorphic epitheliotropic intestinal T-cell lymphoma, intestinal T-cell lymphoma not otherwise specified, indolent T-cell lymphoproliferative disorder of the GI tract and indolent NK-cell lymphoproliferative disorder of the GI tract (previously known as NK-cell enteropathy).

Therapeutic outcomes and safety of radiofrequency ablation for primary papillary thyroid carcinoma: A game-changing meta-analysis.

Background: Radiofrequency ablation (RFA) is an emerging treatment option for small, low-risk papillary thyroid carcinoma (PTC). This systematic review and meta-analysis aimed to evaluate and compare the efficacy and safety profiles of RFA for primary T1a vs. T1b PTC.

Breast cancer outcomes after skin- and nipple-sparing mastectomy in BRCA pathogenic mutation carriers versus non-BRCA carriers.

Unlabelled: Our previous study on BRCA breast cancer carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.

Methods: The study was approved by the institutional ethics committee.

Mapping the aging brain: Insights into microstructural changes from free water-corrected fractional anisotropy.

Aging has a significant impact on brain structure, demonstrated by numerous MRI studies using diffusion tensor imaging (DTI). While these studies reveal changes in fractional anisotropy (FA) across different brain regions, they tend to focus on white matter tracts and cognitive regions, often overlooking gray matter and motor areas. Additionally, traditional DTI metrics can be affected by partial volume effects.

Discordance in acute gastrointestinal toxicity between synchrotron-based proton and linac-based electron ultra-high dose rate irradiation.

Purpose: Proton FLASH has been investigated using cyclotron and synchrocyclotron beamlines but not synchrotron beamlines. We evaluated the impact of dose rate (ultra-high [UHDR] vs. conventional [CONV]) and beam configuration (shoot-through [ST] vs.

Amyotrophic lateral sclerosis caused by FUS mutations: advances with broad implications.

Autosomal dominant mutations in the gene encoding the DNA and RNA binding protein FUS are a cause of amyotrophic lateral sclerosis (ALS), and about 0·3-0·9% of patients with ALS are FUS mutation carriers. FUS-mutation-associated ALS (FUS-ALS) is characterised by early onset and rapid progression, compared with other forms of ALS. However, different pathogenic mutations in FUS can result in markedly different age at symptom onset and rate of disease progression.

Unique considerations in the assessment and management of traumatic brain injury in older adults.

The age-specific incidence of traumatic brain injury in older adults is rising in high-income countries, mainly due to an increase in the incidence of falls. The severity of traumatic brain injury in older adults can be underestimated because of a delay in the development of mass effect and symptoms of intracranial haemorrhage. Management and rehabilitation in older adults must consider comorbidities and frailty, the treatment of pre-existing disorders, the reduced potential for recovery, the likelihood of cognitive decline, and the avoidance of future falls.

Apixaban versus aspirin for stroke prevention in people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack: subgroup analysis of the ARTESiA randomised controlled trial.

Background: People with subclinical atrial fibrillation are at increased risk of stroke, albeit to a lesser extent than those with clinical atrial fibrillation, leading to an ongoing debate regarding the benefit of anticoagulation in these individuals. In the ARTESiA trial, the direct-acting oral anticoagulant apixaban reduced stroke or systemic embolism compared with aspirin in people with subclinical atrial fibrillation, but the risk of major bleeding was increased with apixaban. In a prespecified subgroup analysis of ARTESiA, we tested the hypothesis that people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack, who are known to have an increased risk of recurrent stroke, would show a greater benefit from oral anticoagulation for secondary stroke prevention compared with those without a history of stroke or transient ischaemic attack.

Intranasal oxytocin for apathy in people with frontotemporal dementia (FOXY): a multicentre, randomised, double-blind, placebo-controlled, adaptive, crossover, phase 2a/2b superiority trial.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

Safety and efficacy of satralizumab in patients with generalised myasthenia gravis (LUMINESCE): a randomised, double-blind, multicentre, placebo-controlled phase 3 trial.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.

Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.
