Abstract
BACKGROUND Adalimumab (ADA) biosimilars have entered the therapeutic armamentarium of inflammatory bowel disease (IBD), allowing for the treatment of a greater number of patients for their reduced cost than the originator. However, comparative data on the efficacy and safety of the various ADA biosimilars remains scarce.We compare the efficacy and safety of ADA biosimilars SB5, ABP501, GP2017, and MSB11022 in treating IBD outpatients in a real-life Italian setting. METHODS A retrospective analysis was performed on consecutive IBD outpatients with complete clinical, laboratory, and endoscopic data. Clinical activity was measured using the Mayo score in ulcerative colitis (UC) and the Harvey-Bradshaw Index in Crohn's disease (CD). The primary endpoints were the following: (1) induction of remission in patients new to biologics and patients new to ADA but previously exposed to other anti-tumor necrosis factor agents or other biologics; (2) maintenance of remission in patients switched from the ADA originator to an ADA biosimilar; and (3) safety of various biosimilars. RESULTS A total of 533 patients were enrolled according to the inclusion criteria: 162 patients with UC and 371 patients with CD. Clinical remission was obtained in 79.6% of patients new to biologics and 59.2% of patients new to ADA but not to other biologics; clinical remission was maintained in 81.0% of patients switched from the originator, and adverse events were recorded in 6.7% of patients. There was no significant difference between the 4 ADA biosimilars for each predetermined endpoint. CONCLUSIONS Adalimumab biosimilars are effective and safe in IBD treatment, both in new patients and in patients switched from the ADA originator. No difference in efficacy and safety was found between ADA biosimilars.

Abstract
Iron is a fundamental element in human history, from the dawn of civilization to contemporary days. The ancients used the metal to shape tools, to forge weapons, and even as a dietary supplement. This last indication has been handed down until today, when martial therapy is considered fundamental to correct deficiency states of anemia. The improvement of the martial status is mainly targeted with dietary supplements that often couple diverse co-factors, but other methods are available, such as parenteral preparations, dietary interventions, or real-world approaches. The oral absorption of this metal occurs in the duodenum and is highly dependent upon its oxidation state, with many absorption influencers possibly interfering with the intestinal uptake. Bone marrow and spleen represent the initial and ultimate step of iron metabolism, respectively, and the most part of body iron circulates bound to specific proteins and mainly serves to synthesize hemoglobin for new red blood cells. Whatever the martial status is, today's knowledge about iron biochemistry allows us to embrace exceedingly personalized interventions, which however owe their success to the mythical and historical events that always accompanied this metal.

Plain language summary
This opinion article explores the role of an individual’s nutrition status when subjected to infection by viruses, in particular Covid-19. Distinction is made between the susceptibility to infection in the first instance and the ability to persist in fighting infection once it is established. For Covid-19, it is argued that a healthier nutritional status, in particular Vitamins A, B, C, D and E, iron selenium and zinc, will lower susceptibility to infection, lower the severity of the virus and therefore reduce the length of time an individual has to find reserves to fight the virus. More severe cases of Covid-19 infection also often include gastro-intestinal symptoms which further exacerbate nutritional status with lowered appetite. The authors conclude that malnourished individuals may be more susceptible to Covid-19 infection and that nutritional support is vital in severe cases. The article includes a useful diagram of both hyponutrition and hypernutrition and possible impacts of Covid-19.

Abstract
Altered martial indices before orthopedic surgery are associated with higher rates of complications and greatly affect the patient's functional ability. Oral supplements can optimize the preoperative martial status, with clinical efficacy and the patient's tolerability being highly dependent on the pharmaceutical formula. Patients undergoing elective hip/knee arthroplasty were randomized to be supplemented with a 30-day oral therapy of sucrosomial ferric pyrophosphate plus L-ascorbic acid. The tolerability was 2.7% among treated patients. Adjustments for confounding factors, such as iron absorption influencers, showed a relevant response limited to older patients (≥ 65 years old), whose uncharacterized Hb loss was averted upon treatment with iron formula. Older patients with no support lost -2.8 ± 5.1%, while the intervention group gained +0.7 ± 4.6% of circulating hemoglobin from baseline (p = 0.019). Gastrointestinal diseases, medications, and possible dietary factors could affect the efficacy of iron supplements. Future opportunities may consider to couple ferric pyrophosphate with other nutrients, to pay attention in avoiding absorption disruptors, or to implement interventions to obtain an earlier martial status optimization at the population level.
