Key clinical point: Spending more time outdoors in the summer and higher exposure to summer ultraviolet radiation (UVR) markedly reduces the risk of developing pediatric multiple sclerosis (MS).

Major finding: Compared with spending <30 minutes outdoors daily during the most recent summer, greater time spent outdoors was associated with a significantly decreased risk of developing MS (30-60 minutes: adjusted odds ratio [aOR], 0.48; P = .05; 1-2 hours: aOR, 0.19; P < .001). Additionally, the ambient UVR dose also showed a protective effect (aOR, 0.76; P = .01).

Study details: This was a multicenter case-control study involving children with MS (n=332) compared with age- and gender-matched controls (n=534).

Disclosures: This study was funded by the NIH and the National MS Society. Some of the authors declared receiving grants from National MS Society and NIH and/or financial support and consulting/personal fees from various other sources.

Key clinical point: Patients with multiple sclerosis (MS) are at an increased risk for cancer than the general population.

Major finding: Compared with the general population, patients with MS were at a significantly higher risk for cancer (hazard ratio [HR], 1.36; 95% CI, 1.29-1.43), particularly prostate cancer (HR, 2.08; 95% CI, 1.68-2.58), colorectal and anal cancer (HR, 1.35; 95% CI, 1.16-1.58), and trachea bronchus and lung cancer (HR, 2.36; 95% CI, 1.96-2.84).

Key clinical point: Cognitive impairments may be evaluated up to 30 days before and up to 550 days after a relapse, beyond which they revert to prerelapse levels in patients with relapsing-remitting multiple sclerosis (RRMS).

Major finding: From 30 days prerelapse to 550 days postrelapse, there was a significant drop in the Symbol Digit Modalities Test (SDMT) score, with the largest decline occurring at 0-30 days postrelapse (β-coefficient, −4.00; 95% CI, −4.61 to −3.39) compared with the period of remission.

Study details: This nationwide cohort study recorded 31,529 SDMTs from among 3,877 patients with incident RRMS, each having a minimum of 2 SDMT scores recorded.

Disclosures: This study was funded by a postdoctoral fellowship award to KA McKay from the Swedish Research Council for Health, Working Life, and Welfare (Forte). The authors reported no conflict of interests.

Key clinical point: Treatment with interferon (IFN)-beta 1A improved the SARS-CoV-2-mRNA vaccine-specific humoral response in patients with multiple sclerosis (MS), which was significantly reduced in patients treated with cladribine, fingolimod, or ocrelizumab.

Major finding: Antispike immunoglobulin (Ig)G levels were significantly higher in IFN-treated patients with MS vs healthy controls (median, 1,916 vs 1,089; P = .029); however, antispike IgG levels were significantly lower in patients treated with cladribine (P = .002), fingolimod (P < .0001), or ocrelizumab (P < .0001).

Study details: This was a prospective monocentric study involving 149 patients with MS treated with disease-modifying therapies who were age- and gender-matched to 26 healthy controls, all of whom had no history of SARS-CoV-2 infection and received 2 doses of BNT162b2-mRNA COVID-19 vaccine.

Key clinical point: Discontinuation of natalizumab seemed safe in patients with multiple sclerosis (MS), who converted to secondary MS during treatment, with a high annual relapse rate (ARR) before natalizumab treatment being a risk factor for early relapse posttreatment discontinuation.

Major finding: After natalizumab discontinuation, conversion to secondary MS during treatment was protective for disease reactivation (odds ratio [OR], 0.08; P = .03), whereas ARR before treatment was the only risk factor for early relapse (OR, 1.46; P = .014).

Study details: This was a retrospective analysis of 235 patients with MS who were treated with natalizumab, of whom 105 discontinued the treatment.

Key clinical point: COVID-19 vaccines are safe and elicit a protective humoral response in most patients with multiple sclerosis (MS) who were treated with disease-modifying treatments (DMTs) or remained untreated, except for some patients treated with fingolimod or ocrelizumab.

Major finding: Overall, 86.8% of patients developed a positive humoral response against SARS-CoV-2, with only some patients treated with fingolimod (22.2%) or ocrelizumab (66%) failing to produce a significant humoral response (P < .01). Moreover, immunoglobulin G levels against SARS-CoV2 were significantly lower in patients treated with fingolimod or ocrelizumab than those treated with other DMTs or those who remained untreated (P < .01). None of the patients experienced any adverse events requiring hospitalization.

Study details: This was a prospective cohort study involving 140 patients with MS who were treated with different DMTs and had received vaccination for COVID-19 (mostly BNT162b2).

Key clinical point: Between 2005 and 2019, sorafenib therapy has led to improvement in clinical outcomes among treatment-naïve patients with advanced hepatocellular carcinoma (HCC) in concurrence with a decrease in the median duration of therapy.

Main finding: While the median duration of therapy decreased by 53%, from 23.1 weeks to 12.2 weeks (P = .003) over the study period, the median overall survival increased by 4.5 months (P = .048) and the objective response rate increased by 6 months (P = .003).

Study details: This was an analysis of 16 randomized clinical trials (9 phase 3 and 7 phase 2) conducted from 2005-2019, wherein sorafenib was administered to 4,086 patients with advanced HCC naïve to systemic therapy to compare its effect relative to another systemic therapy or placebo.

Key clinical point: Having undergone drug-eluting bead transarterial chemoembolization (DEB-TACE), treatment response and disease-free survival (DFS) in patients with hepatocellular carcinoma (HCC) could be predicted by MRI signal intensity in the hepatobiliary phase (HBP) and serum alpha-fetoprotein (AFP) levels, respectively.

Main finding: The only significant predictive factors of noncomplete response and short DFS were signal intensity heterogeneity in the HBP (adjusted odds ratio, 4.807; P = .048) and elevated serum AFP levels (≥30 ng/mL; adjusted hazard ratio, 2.916; P = .040), respectively.

Key clinical point: Compared with radiofrequency ablation (RFA), microwave ablation (MWA) effectuates better 1- and 2-year disease-free survival (DFS) along with a lower risk of major complications in patients with hepatocellular carcinoma (HCC).

Main finding: Although both ablation therapies led to a similar 2-year overall survival (P = .573), MWA achieved better 1-year DFS (79.7% vs 60.7%; P = .035) and 2-year DFS (72.5% vs 45.4%; P = .02) rates than RFA. Concurrently, MWA showed a lower rate of major complications than RFA (14% vs 29%; P = .043).

Study details: Findings are from a retrospective cohort study involving 150 patients with HCC, including treatment-naïve and recurrent HCC, who were treated with either RFA (n=100) or MWA (n=50).

Main finding: Although both ablation therapies led to a similar 2-year overall survival (P = .573), MWA achieved better 1-year DFS (79.7% vs 60.7%; P = .035) and 2-year DFS (72.5% vs 45.4%; P = .02) rates than RFA. Concurrently, MWA showed a lower rate of major complications than RFA (14% vs 29%; P = .043).

Study details: Findings are from a retrospective cohort study involving 150 patients with HCC, including treatment-naïve and recurrent HCC, who were treated with either RFA (n=100) or MWA (n=50).

Key clinical point: Compared with radiofrequency ablation (RFA), microwave ablation (MWA) effectuates better 1- and 2-year disease-free survival (DFS) along with a lower risk of major complications in patients with hepatocellular carcinoma (HCC).
