This review aims to elucidate the safety, potential benefits, and recommendations regarding exercise and training in individuals with SCD. SCD patients are characterized by decreased exercise capacity and tolerance. Acute intense exercise may be accompanied by biological changes (acidosis, increased oxidative stress, and dehydration) that could increase the risk of red blood cell sickling and acute clinical complications. However, recent findings suggest that controlled exercise training is safe and well tolerated by SCD patients and could confer benefits in disease management. Regular endurance exercises of submaximal intensity or exercise interventions incorporating resistance training have been shown to improve cardiorespiratory and muscle function in SCD, which may improve quality of life. Recommendations for exercise prescription in SCD should be based on accurate clinical and functional evaluations, taking into account disease phenotype and cardiorespiratory status at rest and in response to exercise. Exercise programs should include gradual progression, incorporating adequate warm-up, cool-down, and hydration strategies. Exercise training represents promising therapeutic strategy in the management of SCD.

Out-of-pocket costs, which include laboratory costs, contribute to the financial burden that patients must bear for healthcare.

Anemia accounts for 68.4 million years of life lived with a disability.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; Data from Scripps-Kaiser and the National Health and Nutrition Examination Survey highlights the prevalence of anemia in the United States to be highest in Black women (or those who menstruate).&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; Recent data from Canada showed the correlation between anemia and socioeconomic status with lower household income associated with the greatest odds of anemia.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Various factors contribute to the burden of anemia in women of color, including disproportionately higher rates of heavy menstrual bleeding (HMB) from fibroids.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; HMB, defined as greater than 80 mL blood loss per month or excessive menstrual blood loss that interferes with a woman's physical, emotional, social, and material quality of life, depletes iron stores leading to iron deficiency.&lt;span&gt;&lt;sup&gt;5&lt;/sup&gt;&lt;/span&gt; HMB has been reported to affect between 10% and 30% of reproductive age women in the United States, with a symptom duration of years commonly reported.&lt;span&gt;&lt;sup&gt;6&lt;/sup&gt;&lt;/span&gt; These numbers are even higher in persons with a bleeding disorder or on anticoagulation.&lt;span&gt;&lt;sup&gt;7&lt;/sup&gt;&lt;/span&gt; Iron deficiency leads to fatigue, impaired cognitive function, and decreased mood, leading to loss of quality of life and personal productivity.&lt;span&gt;&lt;sup&gt;8&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;HMB and resultant iron deficiency require frequent healthcare visits and laboratory monitoring.

Therapies for AL often draw inspiration from successful treatments in multiple myeloma (MM). However, the field faced a challenge when second-generation proteasome inhibitors and immunomodulatory drugs (IMiDs) used for MM proved poorly tolerated by AL patients, creating a significant treatment gap between the two diseases. The ANDROMEDA trial marked a turning point by combining daratumumab, a CD38-directed monoclonal antibody, with the previous standard of care—bortezomib, cyclophosphamide, and dexamethasone (VCd). This combination dramatically improved response rates, with approximately 80% of patients achieving a “≥” very good partial response (VGPR), compared to 50% with VCd alone.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Before the ANDROMEDA trial, approximately one-third of AL patients eventually required a second line of treatment (2nd LoT), often due to an unsatisfactory hematologic response (less than partial response [PR]), hematologic progression/relapse, and lack of organ response.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; The landscape of 2nd LoT in the daratumumab era and the outcomes of such treatments are poorly characterized. Our study addresses this knowledge gap by examining the real-world outcomes of 100 consecutive patients with newly diagnosed AL who received upfront daratumumab-based therapy between January 2018 and December 2023.&lt;/p&gt;&lt;p&gt;The median age was 67.6 years [39.6–91.1]; 60% of patients were male; and the majority were White (67.3%) (Table S1). NYHA Class was III/IV in 44.3% at diagnosis. Most had lambda light chain involvement (76%), and median dFLC was 229 mg/L [2–9069]. Median NT-proBNP was 3317 ng/L [22–70 000], 26.9% ≥8500 ng/L. Median HS troponin-T was 64 ng/L [10–405]. Median BMPC percentage was 15% [2–70]. Regarding cytogenetics, 46% had &lt;i&gt;t&lt;/i&gt;(11;14), 39.4% had del(13q), 40% had 1q gain/amplification, 28.6% had hyperdiploidy, and 13.4% had high-risk myeloma abnormalities. Most patients had modified Mayo 2004 stage IIIA (39.2%) or IIIB (24.7%) and renal stage II (46.3%). The most common frontline regimen was Dara-VCd (91%), followed by Dara-Vd/Dara-ixazomib-d (4%), Dara-d (4%), and Dara-Cd (1%), and 13% underwent ASCT consolidation. Comparing baseline characteristics between patients who received 2nd LoT versus those who did not, significant differences were noted in dFLC and %BMPC, with dFLC &gt;180 mg/L in 78.8% versus 51.5% respectively (&lt;i&gt;p&lt;/i&gt; = .005) and BMPC &gt;15% in 67.6% versus 40.7% respectively (&lt;i&gt;p&lt;/i&gt; = .02).&lt;/p&gt;&lt;p&gt;Median follow-up after 1st LoT was 22.3 months [2–69.7], with hematologic response evaluable for 84/100 patients. Most achieved either CR (46.4%), low-dFLC-PR (3.6%), or VGPR (21.4%) (Table S2). Twenty-three patients had either a PR (13.1%) or no response (NR) (15.5%) and received 2nd LoT. Overall, 34% required a 2nd LoT.
