[Perioperative anticoagulant therapy in a patient with congenital antithrombin III deficiency undergoing posterior spinal fusion].

A 22-year-old female was scheduled to undergo posterior thoracolumbar spinal fusion. She had been diagnosed with congenital antithrombin III (AT-III) deficiency by the onset of pulmonary embolism and deep vein thrombosis after the first operation at the age of 18. Thereafter she had taken warfarin, 5 mg daily, until 4 days before the surgery. Preoperatively, we administered AT-III products to regulate AT-III activity. The posterior spinal fusion was performed successfully without surgical complications. Postoperatively, we continued administration of AT-III products to maintain AT-III activity above 75%. We also used low dose unfractionated heparin with AT-III by continuous intravenous infusion. Heparin was administered with dose adjustment to achieve a target activated partial thromboplastin time of 45 to 60 seconds. After the activated partial thromboplastin time was stabilized in the target range, we started warfarin therapy (target international normalized ratio, 1.5 to 2.5) on postoperative day 16 and stopped administration of heparin on postoperative day 19. There was no thrombosis complications during the perioperative period. Good anticoagulant management was achieved in a patient with congenital AT-III deficiency undergoing posterior spinal fusion.

Auditory interaction between runners: Does footstep sound affect step frequency of neighboring runners?

This study aimed to investigate the effect of footsteps of a neighboring runner (NR) on the main runner's step frequency (SF), heart rate (HR), and rating of perceived exertion (RPE). The participants were male long-distance runners belonging to a university track and field team. Two experiments were conducted in which the main runner (participant) and NR (examiner) ran with the same running speed on two adjacent treadmills separated by a thin wall. The participants were instructed that the experimental purpose was to investigate the HR when running with others and running alone. In Experiment 1, NR performed three trials of changing the footstep tempo in 5 bpm (beat per minute) faster (+5bpmFS), 5 bpm slower (-5bpmFS), or no footsteps (NF) conditions. The results showed that the footstep condition affected the variability of the SF but not the mean SF. Next, Experiment 2 was conducted by increasing the footstep tempo condition. NR performed seven trials of changing the footstep tempo by ±3 bpm, ±5 bpm, ±10 bpm, or no footstep. The results showed that the footstep condition affected the mean SF and the SF decreased at -10bpmFS compared to NF. There were no differences in the HR and RPE between conditions. These results indicated that the footsteps of NR could influence the SF, although it was unclear whether footsteps were involved in the synchronization between runners. Overall, our findings emphasize the environmental factors that influence running behavior, including the NR's footsteps.

Effect of Chronic Kidney Disease or Anemia or Both on Cardiovascular Mortality in a 25-Year Follow-Up Study of Japanese General Population (From NIPPON DATA90).

The relation between chronic kidney disease (CKD) and cardiovascular disease (CVD) in the general population is well elucidated. In patients with CKD, anemia is associated with adverse outcomes. However, the effects of CKD and anemia on CVD in the general population remains poorly explored, especially in Asian populations. This study aimed to investigate the effect of CKD and/or anemia on CVD mortality in a long-term cohort study involving Japanese community dwellers. We assessed 7,339 participants (aged ≥30 years) with no CVD history. These participants were divided into 4 categories according to their CKD (estimated glomerular filtration rate <60 or urine protein >1+ by dipstick qualitative test) and/or anemia (hemoglobin: <13 g/100 ml [men], <12 g/100 ml [women]) statuses. For each category, we calculated the hazard ratios (HRs) of CVD mortality by using the Cox proportional hazards model after adjusting for age, body mass index, hypertension, diabetes, dyslipidemia, smoking, and alcohol drinking. Within 25 years of follow-up, 637 participants died because of CVD. The HRs of CVD in patients with CKD only, anemia only, and both were 1.27, 1.59, and 2.60 (95% confidence intervals [CI] 1.06 to 1.53, 1.34 to 1.90, and 1.80 to 3.76) in men and 1.42, 1.08, and 2.00 (95% CI 1.19 to 1.69, 0.99 to 1.18, and 1.54 to 2.60) in women, respectively. In conclusion, CKD with anemia is associated with an increased risk for CVD mortality in a general population in Japan.

Effects of oral administration of colostrum whey in peripartum goat on antimicrobial peptides in postpartum milk.

The present study was conducted to examine whether colostrum supplementation in peripartum goats increases the antimicrobial peptides in their milk. Goats were orally administered 2 ml of colostrum whey products (colostrum group) or water (control group) daily, from 2 weeks before until 2 weeks after kidding. Body weights of mothers and kids were measured. Blood, milk, and fecal samples were collected from the mothers, and blood samples were collected from the kids. Concentrations of milk antimicrobial peptides (beta-defensin, cathelicidin, lactoferrin, S100A7, lactoperoxidase, and immunoglobulin A [IgA]) were determined. IgA and nutritional parameters (glucose, total cholesterol, triglyceride, ketone bodies, and non-esterified fatty acids) were also determined in the blood of mothers and kids. Milk IgA and lactoferrin concentrations were higher in the colostrum group than in the control group. Conversely, lower milk concentrations of S100A7 were observed in the colostrum group than that in the control group. Plasma IgA concentrations were higher for kids from the colostrum group than for those from the control group. These results suggest that oral administration of colostrum in pregnant goats increases IgA concentration in postpartum milk, which can subsequently improve the health of their kids.
