The diagnostic dilemma of adrenal vascular tumors: analysis of 21 cases and systematic review of the literature.

Purpose: Adrenal vascular tumors are mainly represented by adrenal cavernous hemangiomas (ACHs) and adrenal cystic lymphangiomas (ACLs). Their radiological features often overlap with malignant tumors, therefore ruling out malignancy becomes mandatory. We analyzed clinical, radiological, and histopathological data to identify specific characteristics of these tumors.

The impact of neoadjuvant therapy in patients with left-sided resectable pancreatic cancer: an international multicenter study.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.

Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

Voluntary wheel running decreases amyloidogenic pathway and rescues cognition and mitochondrial energy metabolism in middle-aged female 3xTg-AD mouse model of Alzheimer's disease.

Background: Evidence supports the neuroprotective effects of physical activity, either in experimental animal models or humans. However, the biological mechanisms by which physical exercise modulates dementia and Alzheimer's disease (AD) progression are still unclear.

Objective: This study investigated whether long-term (6 months) of voluntary wheel running induces neuroprotective effects in the pathogenesis of AD in middle-aged (8 months) female mice, focusing on energy metabolism.

Clinicopathological predictive factors in long-term survivors who underwent surgery for pancreatic ductal adenocarcinoma: A single-center propensity score matched analysis.

Background: Long-term survivors (LTSs) after pancreatic resection of pancreatic ductal adenocarcinoma (PDAC) represent a particular subgroup of patients that remains poorly understood. The primary endpoint was to identify clinicopathological factors associated with LTSs after pancreatic resection for PDAC.

Methods: This was a retrospective study of patients who had undergone pancreatic resection for PDAC.

Short-term exercise counteracts accelerated ageing impacts on physical performance and liver health in mice.

Senescence impairs liver physiology, mitochondrial function and circadian regulation, resulting in systemic metabolic dysregulation. Given the limited research on the effects of combined exercise on an ageing liver, this study aimed to evaluate its impact on liver metabolism, circadian rhythms and mitochondrial function in senescence-accelerated mouse-prone 8 (SAMP8) and senescence-accelerated mouse-resistant 1 (SAMR1) mice. Histological, reverse transcription quantitative polymerase chain reaction (RT-qPCR) and immunoblotting analyses were conducted, supplemented by transcriptomic data sets and AML12 hepatocyte studies.

Mitigating neuroinflammation in cognitive areas: exploring the impact of HMG-CoA reductase inhibitor.

Existing literature suggests that infection-specific mechanisms may play a significant role in the onset and progression of dementia, as opposed to the broader phenomenon of systemic inflammation. In addition, 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A (CoA) reductase inhibitors have been proposed as a potential therapeutic approach for sepsis, given their anti-inflammatory and antioxidant properties. We investigated the neuroprotective effect of an HMG-CoA reductase inhibitor (simvastatin) by analyzing neurodegenerative markers, mitochondrial respiration, and neuronal tracing in the prefrontal cortex (PFC) and thalamic nucleus reuniens (RE) of sepsis survivor animals.

EMC1 Is Required for the Sarcoplasmic Reticulum and Mitochondrial Functions in the Muscle.

EMC1 is part of the endoplasmic reticulum (ER) membrane protein complex, whose functions include the insertion of transmembrane proteins into the ER membrane, ER-mitochondria contact, and lipid exchange. Here, we show that the gene is expressed in the somatic musculature and the protein localizes to the sarcoplasmic reticulum (SR) network. Muscle-specific RNAi led to severe motility defects and partial late pupae/early adulthood lethality, phenotypes that are rescued by co-expression with an transgene.

RANKL signaling drives skeletal muscle into the oxidative profile.

The bone-muscle unit refers to the reciprocal regulation between bone and muscle by mechanical interaction and tissue communication via soluble factors. The RANKL stimulation induces mitochondrial biogenesis and increases the oxidative capacity in osteoclasts and adipocytes. RANKL may bind to the membrane bound RANK or to osteoprotegerin (OPG), a decoy receptor that inhibits RANK-RANKL activation.

Adolescent Stress-Induced Ventral Hippocampus Redox Dysregulation Underlies Behavioral Deficits and Excitatory/Inhibitory Imbalance Related to Schizophrenia.

Background And Hypothesis: Redox dysregulation has been proposed as a convergent point of childhood trauma and the emergence of psychiatric disorders, such as schizophrenia (SCZ). A critical region particularly vulnerable to environmental insults during adolescence is the ventral hippocampus (vHip). However, the impact of severe stress on vHip redox states and their functional consequences, including behavioral and electrophysiological changes related to SCZ, are not entirely understood.

Early Versus Late Drainage Removal in Patients Who Underwent Pancreaticoduodenectomy: A Comprehensive Systematic Review and Meta-analysis of Randomized Controlled Trials Using Trial Sequential Analysis.

Background: The superiority of early drain removal (EDR) versus late (LDR) after pancreaticoduodenectomy (PD) has been demonstrated only in RCTs.

Methods: A meta-analysis was conducted using a random-effects model and trial sequential analysis. The critical endpoints were morbidity, redrainage, relaparotomy, and postoperative pancreatic fistula (CR-POPF).

Physical Prehabilitation in Patients who Underwent Major Abdominal Surgery: A Comprehensive Systematic Review and Component Network Meta-Analysis Using GRADE and CINeMA Approach.

Background: Physical prehabilitation is recommended before major abdominal surgery to ameliorate short-term outcomes.

Methods: A frequentist, random-effects network meta-analysis (NMA) was performed to clarify which type of preoperative physical activity among aerobic exercise (AE), inspiratory muscle training (IMT), and resistance training produces benefits in patients who underwent major abdominal surgery. The surface under the P-score, odds ratio (OR), or mean difference (MD) with a 95% confidence interval (CI) were reported.

Transcriptomic analysis reveals mitochondrial pathways associated with distinct adolescent behavioral phenotypes and stress response.

Adolescent individuals exhibit great variability in cortical dynamics and behavioral outcomes. The developing adolescent brain is highly sensitive to social experiences and environmental insults, influencing how personality traits emerge. A distinct pattern of mitochondrial gene expression in the prefrontal cortex (PFC) during adolescence underscores the essential role of mitochondria in brain maturation and the development of mental illnesses.

Immunonutrition in patients who underwent major abdominal surgery: A comprehensive systematic review and component network metanalysis using GRADE and CINeMA approaches.

Background: The benefits of immunonutrition in patients who underwent major abdominal surgery have been recently established, but the optimal combination of immunonutrients has remained unclear. The aim is to clarify this point.

Methods: A systematic search of randomized clinical trials about immunonutrition in major abdominal surgery was made.

Effects of voluntary running on the skeletal muscle of rats with pulmonary artery hypertension.

The effects of voluntary running on the skeletal muscle of rats with pulmonary arterial hypertension (PAH) were tested in the present study. PAH was induced in rats by a single injection of monocrotaline (MCT, 60 mg/kg). Rats in the sedentary hypertension (HS) group had their tolerance to physical exertion reduced throughout the experiment, while those in the sedentary control (SC), exercise control (EC), exercise hypertension (EH) and median exercise (EM) groups maintained or increased.

Value of immunonutrition in patients undergoing pancreatic resection: a trial sequential meta-analysis.

Background: The benefits of immunonutrition (IM) in patients who underwent pancreatic surgery are unclear.

Purpose: The aim is to clarify the use of perioperative chemotherapy in resectable goblet cell carcinoma (GCC).

Methods: A retrospective study was carried out based on the Surveillance, Epidemiology, and End Results study. The population was divided: into patients who received only radical surgery (group A) and those who received radical surgery plus chemotherapy (group B).

Adherence to Guidelines Influenced the Mortality, Hospital Stay, and Health Care System Costs in Patients With Acute Pancreatitis.

Objectives: The primary end point was the compliance rate with guidelines. The secondaries were mortality, hospital stay, and costs.

Methods: This study included 1904 patients with acute pancreatitis (AP): group A, diagnosed before 2013, and group B, after 2013.

Combined physical exercise reverses the reduced expression of Bmal1 in the liver of aged mice.

Aging can modify the morphology and function of the liver, such as generating a decrease in the mitochondria content, autophagy, and cell senescence. Although exercise training has several beneficial effects on hepatic metabolism, its actions on autophagy processes, mitochondrial function, and cellular senescence need to be more widely explored. The present study verified the effects of aging and exercise on hepatic circadian markers, autophagy, and mitochondria activity in 24-month-old mice with a combined exercise training protocol.

IL-6 deletion decreased REV-ERBα protein and influenced autophagy and mitochondrial markers in the skeletal muscle after acute exercise.

Interleukin 6 (IL-6) acts as a pro and anti-inflammatory cytokine, has an intense correlation with exercise intensity, and activates various pathways such as autophagy and mitochondrial unfolded protein response. Also, IL-6 is interconnected to circadian clock-related inflammation and can be suppressed by the nuclear receptor subfamily 1, group D, member 1 (, protein product REV-ERBα). Since IL-6 is linked to physical exercise-modulated metabolic pathways such as autophagy and mitochondrial metabolism, we investigated the relationship of IL-6 with REV-ERBα in the adaptations of these molecular pathways in response to acute intense physical exercise in skeletal muscle.

Trial sequential meta-analysis of laparoscopic versus open pancreaticoduodenectomy: is it the time to stop the randomization?

Background: The advantages of LPD compared with OPD remain debatable. The study aimed to compare the laparoscopic (LPD) versus open (OPD) for pancreaticoduodenectomy.

Methods: A meta-analysis of randomized studies (RCTs) comparing LPD and OPD was made.
