Purpose Of Review: This review examines the long-term efficacy and safety of various nutritional and pharmacological strategies for managing obesity. The focus is on the Mediterranean diet (MedDiet), very low-energy ketogenic therapy (VLEKT), and pharmacological interventions such as naltrexone/bupropion and liraglutide. Given the chronic nature of obesity, understanding the sustainability and impact of these treatments over time is critical.

Background: Cardiac computed tomography (CT) is increasingly used to search for cardioembolic sources of acute ischemic stroke (AIS). We assessed the association between high-risk cardioembolic sources on cardiac CT and AIS.

Methods: We performed a case-control study using data from a prospective cohort including consecutive adult patients with suspected stroke who underwent cardiac CT acquired during the initial stroke imaging protocol between 2018 and 2020.

Article Synopsis
  • The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
  • A special data scouting method is utilized to pick out events with low combined momentum in jets.
  • This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

This novel study applies targeted functional proteomics to examine tissues and cells obtained from a cohort of individuals with severe obesity who underwent bariatric surgery (BS), using a Reverse-Phase Protein Array (RPPA). In obese individuals, visceral adipose tissue (VAT), but not subcutaneous adipose tissue (SAT), shows activation of DNA damage response (DDR) markers including ATM, ATR, histone H2AX, KAP1, Chk1, and Chk2, alongside senescence markers p16 and p21. Additionally, stress-responsive metabolic markers, such as survivin, mTOR, and PFKFB3, are specifically elevated in VAT, suggesting both cellular stress and metabolic dysregulation.

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of sqrt[s]=13  TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3  fb^{-1}. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom.

  • This study investigates the impact of left atrial appendage (LAA) slow-flow on ischemic stroke outcomes, finding that 16% of patients had slow-flow and shared characteristics with those having LAA thrombus.
  • While both slow-flow and thrombus were linked to a higher prevalence of atrial fibrillation, patients with thrombus experienced more severe strokes and worse functional outcomes than those with slow-flow.
  • Ultimately, slow-flow did not significantly affect functional outcomes or major cardiovascular events, but it was associated with an increased risk of stroke recurrence in patients with unknown causes of their strokes.

Introduction: Patient engagement is essential to achieve long-term goals in obesity management. It is crucial to identify patients' perspectives, misperceptions and unmet educational needs on obesity etiology and treatments, to establish a correct therapeutic alliance between healthcare providers and patients.

Methods: Objective: This study, promoted by the regional section of the Italian Obesity Society (SIO Lazio), explores attitudes towards obesity, self-awareness, misperceptions of weight loss strategies, experiences of weight stigma and educational needs of patients living with overweight or obesity.

The production of ϒ(2S) and ϒ(3S) mesons in lead-lead (Pb-Pb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The ϒ(3S) meson is observed for the first time in Pb-Pb collisions, with a significance above 5 standard deviations. The ratios of yields measured in Pb-Pb and pp collisions are reported for both the ϒ(2S) and ϒ(3S) mesons, as functions of transverse momentum and Pb-Pb collision centrality.

A search is presented for baryon number violating interactions in top quark production and decay. The analysis uses data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC with an integrated luminosity of 138  fb^{-1}. Candidate events are selected by requiring two oppositely charged leptons (electrons or muons) and exactly one jet identified as originating from a bottom quark.

Article Synopsis
  • The pandemic of type 2 diabetes (T2D) is mainly caused by excess body fat from long-term energy imbalance, highlighting the importance of weight loss in preventing and treating the condition.
  • Weight regain is common after weight loss and often leads to the return or worsening of T2D, reflecting the biological challenges in maintaining weight loss.
  • Recent studies indicate that bariatric surgery is more effective than traditional treatments for weight loss and T2D remission, while new antihyperglycemic medications also show promise by enhancing fat tissue function, shifting the understanding of how obesity and T2D are interconnected.

Nucleoporins, the components of nuclear pore complexes (NPCs), can play cell type- and tissue-specific functions. Yet, the physiological roles and mechanisms of action for most NPC components have not yet been established. We report that Nup358, a nucleoporin linked to several myeloid disorders, is required for the developmental progression of early myeloid progenitors.

Obesity is a heterogeneous condition which results from complex interactions among sex/gender, sociocultural, environmental, and biological factors. Obesity is more prevalent in women in most developed countries, and several clinical and psychological obesity complications show sex-specific patterns. Females differ regarding fat distribution, with males tending to store more visceral fat, which is highly correlated to increased cardiovascular risk.
