832. Feasibility and safety of impact‑loading exercise in patients with multiple myeloma—a pilot studyAnne Kollikowski, Marei Schallock, Ruben Ringeisen, Dirk Hasenclever, Lothar Seefried, Jan-Peter Grunz, Damir Zubac, Claudia Löffler, Freerk T. Baumann, Franziska Jundt, 2025, izvirni znanstveni članek Povzetek: Purpose Patients with multiple myeloma (MM) develop osteolytic lesions with fractures, pain, and impaired quality of life. Preclinical data show an anabolic effect of loading exercise in osteolytic lesions of MM. This 6-month pilot study evaluated feasibility and safety of impact-loading exercise in patients with MM after assessment of spinal stability. Methods We assigned 20 patients to perform 45 min of guided impact-loading exercise twice a week and home-based training once a week or stretching exercise twice a week. Primary endpoint was assessment of feasibility and safety. Secondary endpoints were assessments of physical performance, quality of life, and bone remineralization. Results Of 77 eligible patients with MM, 26% accepted participation. In the impact group, 9/12 and in the stretching group 7/8 patients completed training with adherence rates of 65.8 and 81.1%. Ninety percent of the stamping and jumping exercises were performed with increasing intensity from the prescribed training volume of ≥ 100%. Low severity pain events were reported after 32.9% of impact sessions. No serious adverse events were observed. After 6 months, 6-minute walk distance increased in the impact group by 35 m and in the stretching group by 46 m, and chair-rise test improved in the stretching group by 1.7 s. Global health status increased by 24.9% in the impact group, and functional scale by 31.9% in the stretching group based upon EORTC QLQ-C30. No signs of bone remineralization were observed in computed tomography. Conclusion Impact training is feasible and appears to be safe in selected MM patients.

834. Acute effects of orofacial, neck, and shoulder relaxation exercises and chewing on soleus H-reflex and motor unit discharge patternsMarša Magdič, Aleš Holobar, Matej Kramberger, Matjaž Vogrin, Nina Murks, Anita Fekonja, Miloš Kalc, 2025, izvirni znanstveni članek Povzetek: The interconnected nature of orofacial, neck musculature, and the neural system suggests that localised19activities, such as teeth clenching, can influence remote spinal excitability. While stretching exercises are20known to have both local and remote effects, the specific impact of orofacial muscle stretching remains21underexplored. This study investigates the effects of two interventions: 25 guided orofacial and neck22stretching and mobility exercises (Exercises), and chewing six chewing gums for six minutes (Chewing),23on the soleus H-reflex and D1 presynaptic inhibition. Ten volunteers (mean age: 28.75 ± 9 years)24participated, with H-reflex measurements collected using high-density electromyography (HDsEMG)25before and after each intervention. Latency (HLAT ), duration (H DUR ), peak-to-peak (H P2P, D1 PSP ) and positive26peak (H POS ) amplitudes were extracted from unconditioned and conditioned H-reflexes. The ratio27(D1 P2P/H P2P) between conditioned (D1 P2P ) and unconditioned (H P2P ) H-reflex was calculated to study the28D1 presynaptic inhibition mechanisms. Additionally, 8,400 firings from 376 distinct motor units (MUs),29categorised by firing threshold were analysed for latency, firing ratio, and inhibition probability (D1 PROB ).30HP2P, HPOS decreased and HDUR was significantly increased after the Exercise intervention, while the31Chewing intervention had no effect on these parameters. The D1 P2P/H P2P ratio and D1 PROB remained32unchanged, suggesting that the observed drop in H P2P is not mediated by presynaptic inhibition33mechanisms. Single MU analysis confirmed the H-reflex findings. The results of this study suggest that34stretching and mobility exercises targeting the neck and orofacial region can reduce neuromuscular35excitability, offering potential for non-pharmacological management of conditions associated with36motoneuron hyperexcitability and general whole-body relaxation

835. Intensity meters : new notes and discoveries on the invention of early modern precision instrumentsFabrizio Bigotti, 2023, izvirni znanstveni članek Povzetek: The article sheds light on the invention of early modern precision instruments and
their application in medicine, by analysing a neglected work by one of the Italian
pupils of the physician Santorio Santori (1561–1636). This source provides vital infor-
mation on Santorio’s experimental sample, and on the practical use and dimensions
of instruments such as thermometers, hygrometers, pulsimeters and precision scales,
showing that they also had a normative purpose: regulating the environmental factors
affecting human health. The article first establishes the derivative nature of the source
from Santorio’s teachings, and then contextualises the invention of precision instru-
ments with regard to Santorio’s published and unpublished output. In the conclusions,
I argue that the new instruments were meant to address the shortcomings of the tradi-
tional diagnostic rationale and are best conceptualised as ‘intensity meters’ meant to
assess ‘the magnitude’ (magnitudo) of a patient’s illness in degrees.

836. A previously unknown path to corpuscularism in the Seventeenth century : Santorio’s Marginalia to the Commentaria in Primam Fen Primi Libri Canonis Avicennae (1625)Fabrizio Bigotti, 2017, izvirni znanstveni članek Povzetek: This paper presents some of Santorio’s marginalia to his Commentaria in primam fen primi libri Canonis Avicennae (Venice, 1625), which I identified in the Sloane Collection of the British Library in 2016, as well as the evidence for their authorship. The name of the Venetian physician Santorio Santori (1561–1636) is linked with the introduction of quantification in medicine and with the invention of precision instruments that, displayed for the first time in this work, laid down the foundations for what we today understand as evidence-based medicine. But Santorio’s monumentale opus also contains evidence of many quantified experiments and displays his ideas on mixtures, structure of matter and corpuscles, which are in many cases clarified and completed by the new marginalia. These ideas testify to an early interest in chemistry within the Medical School of Padua which predates both Galileo and Sennert and which has hitherto been unknown.

837. Commenting on Aristotle with a knife : the heretical anatomies of Bassanio LandiFabrizio Bigotti, 2023, izvirni znanstveni članek Povzetek: Drawingonavarietyof sources, includingmanuscript notes and awidevarietyof published material, this article offers the first analysis in English of Bassanio Landi’s works in their medical and philosophical context. I argue that while Landi’s output is characteristic of its sixteenth-century Paduan milieu, his approach to methodological questions in anatomy and the arts, as well as his paraphrase of Aristotle’s De anima, make it possible to locate him within the heretical tradition that stretches from Pietro Pomponazzi (1462–1525) to Paolo Sarpi (1552–1623).
