Obesity, a global health concern of increasing significance, is characterized by chronic low-grade inflammation (LGCI) that significantly contributes to metabolic dysfunction. This narrative review explores the intricate pathophysiological mechanisms driving LGCI in obesity, emphasizing the role of adipose tissue, immune cell activation, and inflammatory signaling pathways. Hypertrophic adipocytes and infiltrating immune cells, particularly macrophages, release a cascade of pro-inflammatory cytokines, including TNF-α, IL-6, and IL-1β, creating a self-perpetuating cycle of inflammation. These mediators disrupt insulin signaling through JNK and NF-κB pathway activation, leading to systemic insulin resistance, cardiovascular complications, gut dysbiosis and other metabolic disorders. The review further discusses therapeutic strategies to mitigate obesity-related LGCI, focusing on lifestyle interventions, nutritional approaches, and pharmacological agents. Physical activity, specific nutrients, and dietary patterns can modulate inflammatory responses, while anti-obesogenic medicines and bariatric procedures offer additional avenues for intervention. By understanding and addressing the root causes of inflammation in obesity, healthcare professionals can develop targeted strategies to improve metabolic health and overall well-being of individuals with obesity and, ultimately, prevent and manage the wide-ranging complications associated with this condition.

(1) Background: To investigate the real-world effectiveness and safety profile of nusinersen in Croatian paediatric and adult spinal muscular atrophy (SMA) patients. (2) Methods: A retrospective and anonymous collection of relevant demographic and clinical data for all Croatian SMA patients treated with nusinersen and reimbursed by the Croatian Health Insurance Fund (CHIF) between April 2018 and February 2022 was performed through searching the CHIF database and studying the associated reimbursement documentation. All patients who received at least one dose of nusinersen were included in the baseline clinical-demographic overview and safety analysis, whereas only subjects who had completed six doses were included in the effectiveness analysis. (3) Results: Fifty-two patients [61.5% male; median age 13.4 (0.1–51.1) yr.] received nusinersen treatment. In SMA type 1 and type 3 paediatric patients, statistically significant motor function improvement (CHOP INTEND 10.8 ± 10.3 vs. 20.0 ± 15.8, p = 0.003; HFMSE 49.6 ± 7.9 vs. 53.1 ± 7.7, p = 0.008; respectively) was achieved immediately after 4 loading doses of nusinersen and remained statistically significant onwards. Average improvements in HFMSE motor performance in SMA type 2 patients after four, five, and six doses of nusinersen were +6.0, +10.5, and +11.0 points, respectively. In SMA type 3 adult patients, no significant improvement in RHS motor performance or the 6-Minute Walk Test (MWT) was demonstrated. During the study period, 437 doses were administered without any new safety concerns appearing. (4) Conclusions: Our RWD findings indicate that nusinersen is an effective and safe treatment in a heterogeneous group of paediatric patients with all types of SMA; however, no significant benefit (but only RHS and 6MWT maintenance) was demonstrated in SMA type 3 patients who started nusinersen after >18 years of age.

Summary: The aim of the present manuscript is to discuss on potential pros and cons of glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) as glucose‐lowering agents during COVID‐19 pandemic, and what is more to evaluate them as potential candidates for the treatment of patients, affected by COVID‐19 infection, with or even without diabetes mellitus type 2. Besides being important glucose‐lowering agents, GLP‐1RAs pose promising anti‐inflammatory and anti‐obesogenic properties, pulmonary protective effects, as well as beneficial impact on gut microbiome composition. Hence, taking everything previously mentioned into consideration, GLP‐1RAs seem to be potential candidates for the treatment of patients, affected by COVID‐19 infection, with or even without type 2 diabetes mellitus, as well as excellent antidiabetic (glucose‐lowering) agents during COVID‐19 pandemic times.

(1) Background: Data on combination or sequential treatment of spinal muscular atrophy (SMA) with disease-modifying drugs (DMDs) are missing and the latter field is poorly understood. The currently available data of patients on risdiplam previously treated with nusinersen are coming from exploratory research mainly focused on safety. Our aim was to investigate the real-world effectiveness (hypothesising non-inferiority) and safety profile of risdiplam in a paediatric-and-adult nusinersen–risdiplam spinal muscular atrophy switch cohort. (2) Methods: A retrospective and anonymous collection of relevant demographic and clinical data for all Croatian SMA patients switched from nusinersen to risdiplam up to September 2023 (reimbursed by Croatian Health Insurance Fund—CHIF) was performed using the CHIF database and associated reimbursement documentation. Patients were included in effectiveness and safety analysis if they met the following inclusion criteria: (i) risdiplam was reimbursed by the CHIF; (ii) the patient received at least six doses of nusinersen before the switch to risdiplam; (iii) there was no relevant pause between the latter disease-modifying drugs; (iv) availability of all prespecified studied data and parameters. (3) Results: In total, 17 patients met the inclusion criteria (58.9% female; median age 12.75 (3.0–44.5) years). In our ‘switch’ cohort, we demonstrated a non-inferiority of risdiplam to nusinersen in the SMA 1 (+1.0 in CHOP INTEND; p = 0.067), SMA 3p (+0.7 in HFMSE; p = 0.897), and SMA 3a (+0.8 in RHS; p = 0.463) subpopulations, during a one-year follow-up period. There were no reports on respiratory function worsening, feeding worsening, and no lethal events. No new safety concerns were identified, except for the weight gain that arose as a new potential adverse drug reaction ‘signal’ in two patients. (4) Conclusions: We have reported pivotal real-world findings on switching SMA patients from nusinersen to risdiplam and demonstrated its effectiveness (non-inferiority), safety, and tolerability in a heterogenous paediatric-and-adult ‘switch’ cohort; this will further increase the quality and standards of care as well as safety of a notable portion of SMA patients, especially for those who demand the switch from nusinersen to other DMDs for clinical or personal reasons.
