Muscle–Tumor Crosstalk In Exercise Oncology: Exercise-Induced Myokines And Cancer Cachexia, Amirhossein Ahmadi Hekmatikar, Francesco Bettariga, Álvaro López Llorente, Diego Fernández-Lázaro, Katsuhiko Suzuki, D. Maryama Awang Daud

Research outputs 2022 to 2026

Exercise-induced myokines, such as IL-6, irisin, and myostatin, play crucial roles in mediating systemic adaptations and modulating tumor progression. This narrative review synthesizes evidence on how regular moderate-intensity exercise affects the myokine network within the tumor microenvironment (TME) of solid tumors. Results from the 86 included studies indicate that structured training (aerobic: 45–65% VO2 max; resistance: 45–70% 1RM) enhances the expression of beneficial myokines that support immune surveillance, reduce inflammation, and improve muscle–tumor cross-talk. IL-6 demonstrates a dual modulatory effect on inflammation and immunity; irisin contributes to tumor apoptosis, while myostatin downregulation supports muscle integrity and metabolic balance. Evidence suggests …

Healthcare Professionals’ Experiences And Perspectives On Self-Management Education For Breast Cancer Survivors In Australian Primary Care: A Qualitative Study, Meng Yuan Li, Tao Wang, Daniel Terry, Haiying Wang, Isabella Zhao, Jing Yu Tan

Research outputs 2022 to 2026

Purpose: Breast cancer has been recognised as a chronic condition, with survivors experiencing long-term physical and psychosocial effects following treatment. Supporting breast cancer survivors to self-manage their health can optimise health-related quality of life and reduce symptom burden. Self-management education (SME) has been advocated at the policy and programme level in Australian primary care, but its uptake is often limited. This study explores healthcare professionals’ (HCPs) experiences and perceptions of SME in primary care, aiming to identify factors influencing its implementation and to support survivorship care for breast cancer survivors in Australia.

Methods: A qualitative descriptive approach was adopted involving …

Hiding In Plain Sight: A Case Of Intestinal Tuberculosis Masquerading As Benign Lower Gi Bleeding, Lavender Otom, Priyanka Panwar, Gerald Odong, Fatma Kassim, Patricia Okiro, Christopher Opio, Saleem Abdulkarim

Internal Medicine, East Africa

Background Intestinal tuberculosis (TB) represents the most common form of abdominal TB, often affecting the ileocaecal region. Lower gastrointestinal bleeding is an uncommon presentation and may create significant diagnostic uncertainty, particularly in immunocompromised patients and in settings where inflammatory bowel disease is also encountered.

Case Presentation A woman in her sixties from Africa presented with recurrent diarrhoea and intermittent haematochezia over a 6-month period. Initial endoscopic evaluation was nondiagnostic. Cross-sectional imaging later demonstrated multifocal bowel involvement affecting both the small and large bowel, including ileocaecal and rectoanal disease, with associated abdominopelvic lymphadenopathy. Histopathology from repeat colonoscopy biopsy showed caseating granulomas …

May Measurement Month 2023: Results Of An Opportunistic Blood Pressure Screening Campaign In Kenya, Mzee Ngunga, Thomas Beaney, Gabriele Kerr, Bernard Samia, Lilian Mbau, Neil Poulter, Hellen Nguchu, Jeilan Mohamed, Elijah Ogola

Internal Medicine, East Africa

The May Measurement Month (MMM) is a global screening campaign launched in 2017 to raise awareness of raised blood pressure (BP). Kenya has participated in all previous MMM campaigns. Adults aged ≥18 years were recruited through convenience sampling in nine counties of Kenya. Three seated BP readings were taken on each participant, and a questionnaire collected information on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥140mmHg or diastolic BP ≥90mmHg or being on BP-lowering medication. Controlled BP was defined as being on BP-lowering medication with a BP < 140/90mmHg. Multiple imputation was used to estimate missing BP readings. In total, 4,601 were screened, with a mean age of 41.7 years and 42.7% were female. Of all participants, 1,176 (25.6%) had hypertension, of whom 198 (16.8%) were aware, and 190 (16.2%) were on antihypertensive medication. Of those on antihypertensive medication, 65 (34.2%) had controlled BP, and of all participants with hypertension, 5.5% had controlled BP. The mean systolic and diastolic BPs of those on treatment was significantly higher than those without hypertension. Hypertensive disease in a previous pregnancy was associated with higher BP amongst female participants.

The MMM campaign in Kenya identified a substantial …

Antibiotic Administration After Previable Preterm Prelabor Rupture Of Membranes Is Associated With Prolonged Latency, Alexandra L Hammerquist, Alexander M Saucedo, Selina L Bowler, Mohan Pammi, Catherine Eppes, Ignatia Van Den Veyver, Michael D Jochum, Enrico R Barrozo

Duncan NRI Faculty and Staff Publications

Introduction: While antibiotics have been shown to increase the interval to delivery between rupture of membranes and delivery (latency) and improve neonatal outcomes after viable preterm prelabor rupture of membranes (PPROM), this has not been well investigated in the previable PPROM population. We aimed to investigate the association between antenatal antibiotics and latency following previable PPROM. Secondarily, we examined various maternal and neonatal outcomes. We hypothesized that the administration of antibiotics would prolong latency in pregnancies with previable PPROM.

Methods: Single-center retrospective cohort study that included pregnancies diagnosed with previable PPROM between 140/7 and 216/7 and delivered between 2012 and …

Skin Is In: Promoting Breastfeeding Through Immediate Cesarean Skin-To-Skin, Autumn Spencer

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: The Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) and the American College of Obstetricians and Gynecologists identify immediate, uninterrupted skin-to-skin contact as a standard of care that improves neonatal stability, breastfeeding outcomes, and maternal satisfaction. Despite these recommendations, timely initiation following cesarean birth remains inconsistent. At the project site, skin-to-skin initiation averaged 72 minutes after birth, exceeding the 10-minute benchmark, and exclusive breastfeeding rates were below the national standard of 70%. Contributing barriers included workflow variability, unclear role expectations, and inconsistent communication.

Aim of the Project: The aim of the project was to improve infant and maternal …

Biallelic pathogenic variants in PNPT1 cause combined oxidative phosphorylation deficiency 13 (COXPD13) (MIM #614932), linking mitochondrial dysfunction to type I interferon (IFN) activation through cytosolic leakage of mitochondrial double‐stranded RNA (mt‐dsRNA). This mechanism connects mitochondrial disease to interferonopathies such as Aicardi–Goutières syndrome (AGS). We describe a 7‐month‐old female infant with compound heterozygous PNPT1 variants presenting with severe hypotonia, feeding difficulties necessitating gastrostomy, dystonia, and elevated serum lactate. Brain magnetic resonance imaging (MRI) demonstrated marked cerebellar, brainstem, and basal ganglia atrophy, with a lactate peak on MR spectroscopy (consistent with an inverted doublet). Serum immune profiling revealed a mild but elevated …

Objective: Zinc finger E-box-binding homeobox 1 (ZEB1) is a transcription factor primarily known for its regulatory roles in epithelial-to-mesenchymal transition (EMT) and cell fate determination. Recent studies suggest that endothelial ZEB1 signaling promotes blood vessel growth and reduces junctional integrity, although the underlying mechanisms remain unclear. Notably, the role of ZEB1 in the lymphatic vasculature is unknown, and the regulation of lymphatic integrity by VE-cadherin remains poorly defined.

Methods: Here, using an integrated proteomic and transcriptomic approach, we identify ZEB1-dependent signaling pathways associated with cell-cell junction reorganization in lymphatic endothelial cells (LECs).

Results: Loss of ZEB1 reduced VE-cadherin phosphorylation at …

Longitudinal And Cross-Sectional Evidence That Daily Resting And Activity Energy Expenditures Are Independent In Humans, Andrew K Yegian, Elizabeth Pachus, Leanne M Redman, Steven B Heymsfield, K Falkenhain, Alexandra R Harris, Shaji K Chacko, William W Wong, Daniel E Lieberman

Faculty, Staff and Students Publications

Total energy expenditure (TEE) is commonly modelled as the sum of resting energy expenditure (REE), activity energy expenditure (AEE), and diet-induced thermogenesis (DIT). This additive model has recently been challenged by the constrained energy balance model, which proposes that reductions in mass-adjusted REE compensate to some extent for increases in AEE, rendering mass-adjusted TEE effectively invariant. We tested these competing models using two complementary approaches. First, we conducted a short-term longitudinal, repeated-measures experiment in 12 adults who completed 10-day periods of high and low physical activity separated by a washout period. TEE was measured with doubly labelled water, AEE with …

Reciprocal Compensation Of Caspase-2 And P53 Regulates The Dna Damage Response In Hct116 Colon Cancer Cells, Karla E Lopez, Leslie Bandera, Luiza E Coutinho, Karen Zúñiga, Sarah Wright, Lisa Bouchier-Hayes

Faculty, Staff and Students Publications

Caspase-2 has positive and negative effects on tumor growth in different cancer models. The mechanisms determining these dual outcomes of caspase-2 activation are unclear underscoring the need to assess caspase-2 function in different cell types. We report that high caspase-2 expression is associated with lower survival in patients with colon cancer and increased tumor size in HCT116 colon cancer xenografts. We investigated the interplay between caspase-2 and p53 in regulating the proliferation of these cells. While neither of these proteins had much of an effect on cell cycle arrest on their own, deficiency in both caspase-2 and p53 led to …

Background & aims: Most pediatric hepatocellular tumors are classified as hepatoblastoma (HB) or hepatocellular carcinoma (HCC), yet a subset exhibits mixed histological and molecular features. These hepatoblastomas with carcinoma features (HBCs) include cases provisionally designated as hepatocellular neoplasm-not otherwise specified (HCN-NOS). Their biology remains poorly understood, with unresolved questions about their cellular composition and outcomes. It is unclear whether HBCs comprise hybrid cells with combined HB and HCC characteristics (HBC cells) or admixtures of distinct HB and HCC cells. We characterized the biology, etiology, cellular composition, and evolutionary dynamics of HBCs.

Methods: We performed multi-omics profiling - including single-nucleus RNA …

Current oral food challenge (OFC) protocols for food protein-induced enterocolitis syndrome (FPIES) exhibit significant variability, creating potential for inconsistent diagnostic outcomes and severe reactions. Based on the published evidence and our clinical experience, we propose a practical, standardized OFC dosing protocol that emphasizes patient safety, goals based on age-appropriate servings (AASs), and clinical monitoring. A recent systematic review reported that most patients with persistent FPIES who underwent OFCs reacted to just 25% of an AAS, with low rates of severe reactions. Thus, we recommend that most patients undergoing a medically supervised FPIES OFC receive a cumulative dose of 25% AAS, …

Blinded, Bias-Controlled Multi-Rater Evaluation Of Human-Versus-Ai Brain Metastasis Segmentation Using A Hybrid Foundation-Model Framework, Yiding Han, Enze Zhu, Mhd Hasan Ai Mekdash, Omar Awad, Piyush Pathak, Shixiao Liang, Daniel Allan Hamstra, Xizhe Zhang, Zaid Ali Siddiqui, Baozhou Sun

Faculty, Staff and Students Publications

Background: Accurate segmentation of brain metastases (BM) is essential for diagnosis, stereotactic radiosurgery planning, and longitudinal assessment. However, manual contouring is time-intensive, limiting clinical scalability, and exhibits substantial inter-observer variability. This variability complicates objective assessment of automated segmentation methods and challenges interpretation of model performance.

Purpose: To address these limitations, we developed TUM-SAM, a hybrid foundation-model framework for fully automated BM segmentation, and introduced a bias-controlled, blinded multi-rater evaluation paradigm to determine whether AI-based BM segmentation has reached expert-level performance and whether AI-generated contours are preferred by human experts under unbiased assessment.

Methods: TUM-SAM integrates nnU-Net-based lesion detection with a …
