360-Degree Perspectives on Obesity.

Alarming statistics show that the number of people affected by excessive weight has surpassed 2 billion, representing approximately 30% of the world's population. The aim of this review is to provide a comprehensive overview of one of the most serious public health problems, considering that obesity requires an integrative approach that takes into account its complex etiology, including genetic, environmental, and lifestyle factors. Only an understanding of the connections between the many contributors to obesity and the synergy between treatment interventions can ensure satisfactory outcomes in reducing obesity. Mechanisms such as oxidative stress, chronic inflammation, and dysbiosis play a crucial role in the pathogenesis of obesity and its associated complications. Compounding factors such as the deleterious effects of stress, the novel challenge posed by the obesogenic digital (food) environment, and the stigma associated with obesity should not be overlooked. Preclinical research in animal models has been instrumental in elucidating these mechanisms, and translation into clinical practice has provided promising therapeutic options, including epigenetic approaches, pharmacotherapy, and bariatric surgery. However, more studies are necessary to discover new compounds that target key metabolic pathways, innovative ways to deliver the drugs, the optimal combinations of lifestyle interventions with allopathic treatments, and, last but not least, emerging biological markers for effective monitoring. With each passing day, the obesity crisis tightens its grip, threatening not only individual lives but also burdening healthcare systems and societies at large. It is high time we took action as we confront the urgent imperative to address this escalating global health challenge head-on.

[Effects of a Cetraria islandica extract in monotherapy and in association with magnesium in an experimental-induced hepatopathy model]. / Efectele unui extract din Cetraria islandica în monoterapie si în asociere cu magneziul pe un model de hepatopatie indusa experimental.

AIM: To investigate the effects of a Cetraria islandica extract in an animal model of hepatopathy. MATERIAL AND METHODS: The experiments were carried out on Wistar rats, treated intraperitoneally (excepting carbon tetrachloride which was administered orally by esogastric tube), at single daily dose, for 28 days and divided in eight groups of 6 rats each: Group 1: Saline solution (0.5ml/100g bw/day); Group 2: MgSO4 (5mg/kbw/day); Group 3: C. islandica (Ci) extract (21.56mg/kbw/day); Group 4: Ci+MgSO4; Group 5: carbon tetrachloride (CT).(0.1 ml/100g bw/day); Group 6: CT+MgSO4; Group 7: CT+Ci; Group 8: CT+Ci+MgSO4. At the end of the experiment blood samples were taken to assess the effects on the blood parameters,TGO, TGP, GGT, LDH, serum total billirubin, neutrophil phagocytic function (Nitroblue tetrazolium test) and serum complement activity. This parameters were determined with VITROS 750 XRC device, using Johnson&Johnson kits. The results were statistically processed with the help of "t-Student" test. p<0.05 was considered statistically significant. RESULTS: In this carbon tetrachloride-induced hepatopathy animal model, C. islandica extract demonstrated hepatoprotective and immuno-stimulating effects (proved by normalization of glutamic-pyruvic transminase, glutamic-oxalocetic transminase, serum total billirubin, stimulation of neutrophils percentage and phagocytic functions, decreasing the carbon tetrachloride-induced basophilia and monocytosis, especially in association with magnesium). CONCLUSIONS: Further studies are required to confirm the benefits of this association in hepatoprotective and immunomodulating therapies.
