Objective: Arthrodesis of the first metatarsophalangeal joint (MTPJ) is a reliable procedure for treating various pathologies related to this joint. However, non-union is a common and debilitating complication of the procedure. The purpose of this study was to assess whether the use of a mechanical reamer to prepare the joint surface increases the risk of non-union compared to traditional manual osteotomy. Methods: A retrospective study of all patients who underwent their first MTPJ arthrodesis surgery in our medical center between 2010 and 2015. The articular surface preparation of the MTPJ was either manually performed (Group 1) or mechanically conducted with reamers (Group 2). Data regarding demographic characteristics, indications for surgery, osteosynthesis methods, and post-operative complications, including non-union, infection, and revision rates, were collected for all patients. Results: A total of 83 patients with 92 primary first MTPJ arthrodesis (44 cases in Group 1 and 48 cases in Group 2) were included with a mean follow-up time of 45.3 months (SD 16.8). The two groups were comparable in terms of age, gender, comorbidities, indication for surgery, and follow-up time. The non-union rate was 15.9% in Group 1 and 25% in Group 2 (p = 0.28). Group 2 showed a significantly higher rate of revision surgery compared to Group 1 (43.7% vs. 22.7%, p = 0.03). Conclusions: The mechanical reamer group had a higher non-union rate and a significantly higher rate of revision surgery compared to low-energy manual joint preparation. In light of these findings, the use of mechanical reamers for joint preparation in the first MTPJ arthrodesis was discontinued at our medical center.

Hardening of arterial walls associated with elevated postprandial blood glucose levels increases the risk of cardiovascular disease; however, the impact of intermittent aerobic training on reducing arterial stiffness is unknown. The aim of this study was to examine the chronic effects of intermittent aerobic exercise on arterial stiffness during hyperglycemia in middle-aged adults: 30 healthy middle-aged adults were randomly assigned to an 8-week intermittent aerobic training group (n = 15, jogging or running, 30 min/run, 3 times/week, 65% reserve heart rate) and a control group (n = 15, no training). Pulse wave velocity (PWV) of carotid-femoral (cf) and brachial-ankle (ba), heart rate, blood pressure, and blood glucose was measured before a 75 g oral glucose tolerance test (OGTT) and 30, 60, and 90 min after the test, before the exercise intervention, and 4 and 8 weeks after intervention. The baPWV and blood glucose levels before the intervention were elevated at 30, 60, and 90 min in both groups compared to levels before the 75 g OGTT (p < 0.01). The baPWV and blood glucose levels after 4 and 8 weeks of intervention were unchanged in the training group compared to that before the 75 g OGTT, but increased at 30, 60, and 90 min in the control group compared to that before the 75 g OGTT (p < 0.01). The baPWV and blood glucose levels at 30 and 60 min after the 75 g OGTT after 4 and 8 weeks of intervention were lower in the training group than in the control group (p < 0.01). These results indicate that intermittent aerobic exercise training may reduce the acute increase in arterial stiffness after hyperglycemia.

The organs of the male reproductive tract, including the testis, epididymis, prostate, seminal vesicles, and semen, must provide an immunoregulatory environment conducive to germ cell viability and successful fertilization. Many immune components, such as immune cells, have been investigated regarding reproductive immunology and function; however, the investigation of the role of complement in this system has only more recently been gaining traction in research. This review focuses on complement in the male reproductive tract, with the goal of compiling information currently known about complement components detected in male reproductive organs and identifying areas in need of further research. Considering the recent and upcoming research about the noncanonical functions of complement, this information is relevant and applicable in the fields of reproductive immunology, fertility, and immune regulation.
