AbstractAffinity-optimized T cell receptors can enhance the potency of adoptive T cell therapy. Afamitresgene autoleucel (afami-cel) is a human leukocyte antigen-restricted autologous T cell therapy targeting melanoma-associated antigen A4 (MAGE-A4), a cancer/testis antigen expressed at varying levels in multiple solid tumors. We conducted a multicenter, dose-escalation, phase 1 trial in patients with relapsed/refractory metastatic solid tumors expressing MAGE-A4, including synovial sarcoma (SS), ovarian cancer and head and neck cancer (NCT03132922). The primary endpoint was safety, and the secondary efficacy endpoints included overall response rate (ORR) and duration of response. All patients (N = 38, nine tumor types) experienced Grade ≥3 hematologic toxicities; 55% of patients (90% Grade ≤2) experienced cytokine release syndrome. ORR (all partial response) was 24% (9/38), 7/16 (44%) for SS and 2/22 (9%) for all other cancers. Median duration of response was 25.6 weeks (95% confidence interval (CI): 12.286, not reached) and 28.1 weeks (95% CI: 12.286, not reached) overall and for SS, respectively. Exploratory analyses showed that afami-cel infiltrates tumors, has an interferon-γ-driven mechanism of action and triggers adaptive immune responses. In addition, afami-cel has an acceptable benefit–risk profile, with early and durable responses, especially in patients with metastatic SS. Although the small trial size limits conclusions that can be drawn, the results warrant further testing in larger studies.

AbstractBackgroundThe first metatarsophalangeal joint plays a fundamental role during the gait cycle. The Hubscher manoeuvre, which consists of passively dorsiflexing the first metatarsophalangeal joint of an individual in relaxed stance and observing the raising of the medial longitudinal arch, is a clinical test thought to examine the function of the first metatarsophalangeal joint. However, the hallux dorsiflexion achieved during this test is not related to hallux dorsiflexion during gait. On the other hand, unlike kinematic tests, results from kinetic tests have been shown to be strongly correlated with dynamic joint biomechanics. Thus, given the need for valid and reliable tests to evaluate the function of the first metatarsophalangeal joint, this study aimed to assess the reliability of a new kinetic test, namely, the first metatarsophalangeal joint dorsiflexion resistance test.MethodThirty young adults completed two data collection sessions 1 week apart, during which the first metatarsophalangeal joint dorsiflexion resistance test was performed. Intrarater and interrater reliability were assessed using intraclass correlation coefficients (ICC), minimal detectable difference (MDD), standard error of the mean (SEM) and limits of agreements (LoA).ResultsFor the intrarater reliability, the ICC was 0.77 (p < 0.001), the SEM was 6.5 N, the MDD was 18.1 N and the LoA were −7.9 to 26.9 N. For the interrater reliability, the ICC was 0.86 (p < 0.001), the SEM was 6.9 N, the MDD was 19.0 N and the LoA were −6.4 to 21.8 N.ConclusionThe results of this study demonstrate good intra and interrater reliability of the first metatarsophalangeal joint dorsiflexion resistance test, which provides evidence to support its use in clinical and research contexts. Further work is required to establish the test results' relationship with joint kinetics during gait and to provide normative values in individuals with and without musculoskeletal disorders as well as among different age groups and genders to optimise its utilization in clinical and research settings.

AbstractIntroductionTo systematically review the effect of probiotics on oral health during treatment with fixed orthodontic appliances.MethodsPubMed, Embase and the Cochrane Library were searched up to August 2022 using broad MeSH terms and keywords. Randomized clinical trials comparing a probiotic with a control/no treatment; at least 10 patients/group undergoing fixed orthodontic therapy; and reporting at least one oral health‐related parameter were included.ResultsThe most reported parameters in the 14 included studies were the microbiological counts of mutans streptococci and lactobacilli, microorganisms associated with white spot lesions (WSL). A meta‐analysis of these showed a positive effect of probiotics on mutans streptococci. Probiotic treatment led to significantly less patients with high counts and significantly more with low counts of these bacteria. An effect on the lactobacilli counts was not seen. However, the sole clinical study investigating WSL could not demonstrate a clinical effect of probiotics on these lesions. Additionally, one study reported encouraging results of probiotics on bad breath and one on the occurrence of traumatic oral lesions. One study found reduced counts of Porphyromonas gingivalis in the probiotic group. The clinical results of probiotics on plaque index were ambiguous: one study reported that probiotics reduce the plaque and gingival index, and two that probiotics had no significant influence on plaque index.ConclusionProbiotics are a promising option to lower mutans streptococci counts in patients undergoing fixed orthodontic therapy. However, due to the heterogeneity of the studies, it is not possible to draw conclusions about one specific probiotic.
