Association of taurine intake with changes in physical fitness among community-dwelling middle-aged and older Japanese adults: an 8-year longitudinal study.

Introduction: Taurine has diverse valuable biological functions, including antioxidant activity and regulation of osmotic pressure. Maintaining physical fitness from middle age is important for healthy life expectancy. Although taurine administration improves muscle endurance and strength, its role in maintenance remains unclear. We aimed to clarify the longitudinal taurine intake association with fitness changes. Methods: Participants comprised men and women aged ≥40 years who participated in the third (2002-2004; Baseline) and seventh (2010-2012; Follow-up) waves of the National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA) and completed a 3-day dietary weights recording survey at baseline. A table of taurine content was prepared for 751 foods (including five food groups: Seaweed; Fish and shellfish; Meat; Eggs; and Milk and dairy products) from the Standard Tables of Food Composition in Japan (1,878 foods) 2010. Four physical fitness items (knee extension muscle strength, sit-and-reach, one-leg standing with eyes closed, and maximum walking speed) were measured at baseline and follow-up. We analyzed the association of taurine intake with physical fitness change, employing a general linear model (GLM) and trend tests for baseline taurine intake and follow-up fitness change. Adjustments included baseline variables: sex, age, height, weight, educational level, self-rated health, smoking status, depressive symptoms, and clinical history. Results: The estimated average daily taurine intake (standard deviation) was 207.5 (145.6) mg/day at the baseline. When examining the association with the four physical fitness parameters, higher taurine intake positively increased the change in knee extension muscle strength (T1; 0.1, T2; 0.8, T3; 1.1 (kgf) GLM, p < 0.05; p for trend <0.05) and reduced the decline in knee extension muscle strength in the subgroup analysis of participants aged ≥65 years (T1: -1.9, T2: -1.7, T3: -0.4 kgf; GLM p < 0.05, p for trend <0.05). No relationship was found between taurine intake and the remaining three fitness factors. Conclusion: Estimation of taurine intake showed that dietary taurine intake potentially contributes to the maintenance of knee extension muscle strength over 8 years among Japanese community-dwelling middle-aged and older individuals. This is the first study to investigate the association of dietary taurine intake with muscle strength.

Stepwise surgery with variable adjustments for severe blepharochalasis with multiple chemical sensitivity: a case report.

We report a 29-year-old man with blepharochalasis and multiple chemical sensitivity (MCS). Although standard blepharoplasty with aponeurotic fixation was performed, palpebral ptosis recurred after 3 months. Eyelid function and appearance improved after additional operations. A stepwise surgical approach is appropriate in patients with blepharochalasis and MCS.

Sutureless Microvascular Anastomosis using Intravascular Stenting and Cyanoacrylate Adhesive.

BACKGROUND: Microvascular anastomosis using cyanoacrylate adhesive has a reputation among researchers as an alternative to conventional sutures. However, a degree of ingenuity is required to avoid the collapse of the vascular lumen for the duration of the anastomosis. The aim of this study was to determine the feasibility of intravascular stenting (IVaS) as a temporary stent during sutureless microvascular anastomosis with cyanoacrylate adhesive. METHODS: Sixty male Fisher 344 rats were evenly divided into two groups. The right superficial femoral arteries (RSFAs) were transected in each group. Microvascular anastomoses were then performed with the sutureless (SL) method in one group and conventional sutures (CS) in the other group. The diameter of the RSFA, duration of microvascular anastomosis, and the patency of the RSFA were evaluated immediately after anastomosis and 7 days after the surgery. Tissue samples were obtained for pathological consideration. RESULTS: There was no significant difference in the diameter of the RSFAs between the SL and the CS groups. There was no significant difference in the patency rates of the groups. The anastomosis time of the SL group was significantly shorter than that of the CS group, regardless of the experience of the surgeons. A histological analysis showed a comparable level of foreign body reactions in each group. CONCLUSION: IVaS plays a supportive role in sutureless microvascular anastomosis with cyanoacrylate adhesive. The short-term safety of this technique has now been confirmed at the experimental stage.

Phaeoacremonium Tenosynovitis of the Wrist.

A 79-year-old man presented with a painless, soft, subcutaneous mass lesion of the right volar wrist that had been slowly growing for 3 years. A cloudy, yellow serous effusion was aspirated from the punctured mass, from which Phaeoacremonium spp., an extremely rare cause of tenosynovitis, was isolated in culture. Total synovectomy was performed without the use of antifungal agents. No recurrence or complications occurred as of 6 months after surgery. Fungal infection is rare but should be considered in the differentiation of chronic tenosynovitis.

Modification of the Nuss Procedure: The Single-incision Technique.

SUMMARY: The Nuss procedure is a prevalent minimally invasive surgery for pectus excavatum. Although the Nuss procedure has the advantage of leaving less obtrusive scars, the standard technique requires at least 3 skin incisions to insert several instruments. We experienced 7 cases of the modified Nuss procedure using a single incision during a 7-year period. To facilitate passing of the bar, a traction guide was created according to our unique method. There was no need for a bar stabilizer, and no severe intraoperative complications occurred. All patients exhibited satisfactory short-term results; however, 1 patient suffered from bar rotation and required repeat surgery for fixation. Two patients underwent bar removal via the same single incision without any difficulties.
