Along with clinical practice and education, research is among the most important activities for medical doctors. The same is true in cardiovascular surgery: Young cardiovascular surgeons are expected to improve their surgical techniques and prioritize their clinical practice. However, their perspective on the role of research in their field of expertise is unknown. Therefore, we conducted a survey of and discussion with young cardiovascular surgeons to clarify their thoughts and concerns about performing research. Here we review and report the survey and discussion results.

We conducted a questionnaire survey on shift and on-call system targeting under-forty cardiovascular surgeons and obtained responses from 35 surgeons. We report the questionnaire results.

BACKGROUND: The effects of prenatal exposure to toxic elements on birth outcomes and child development have been an area of concern. This study aimed to assess the profile of prenatal exposure to toxic elements, arsenic (As), bismuth (Bi), cadmium (Cd), mercury (total mercury (THg), methylmercury (MHg), inorganic mercury (IHg)), lead (Pb), antimony (Sb) and tin (Sn), and essential trace elements, copper (Cu), selenium (Se) and zinc (Zn), using the maternal blood, cord blood and placenta in the Tohoku Study of Child Development of Japan (N = 594-650). METHODS: Inductively coupled plasma mass spectrometry was used to determine the concentrations of these elements (except mercury). Levels of THg and MeHg were measured using cold vapour atomic absorption spectrophotometry and a gas chromatograph-electron capture detector, respectively. RESULTS: Median concentrations (25th-75th) of As, Cd, Pb, Sb, Sn and THg in the maternal blood were 4.06 (2.68-6.81), 1.18 (0.74-1.79), 10.8 (8.65-13.5), 0.2 (0.06-0.40) and 0.2 (0.1-0.38) ng mL and 5.42 (3.89-7.59) ng g, respectively. Median concentrations (25th-75th) of As, Cd, Pb, Sb, Sn and THg in the cord blood were 3.68 (2.58-5.25), 0.53 (0.10-1.25), 9.89 (8.02-12.5), 0.39 (0.06-0.92) and 0.2 (0.2-0.38) ng mL and 9.96 (7.05-13.8) ng g, respectively. CONCLUSIONS THg and Sb levels in the cord blood were twofold higher than those in the maternal blood. Cord blood to maternal blood ratios for As, Cd and Sb widely varied between individuals. To understand the effects of prenatal exposure, further research regarding the variations of placental transfer of elements is necessary.

Objective: While electromyographic data on healthy individuals during aquatic exercise have been reported, few studies have examined long-term changes in patients’ muscle strength after 30-day intervention. This study aims to study the long-term effects of repeated hot spring aquatic exercise combined with physical therapy on patients’ muscle strength and endurance. Methods: A total of 12 patients (mean age: 71.9±13.1; FIM score: 117±7.5; the number of patients with cerebrovascular disease: 5; and the number of patients with orthopedic disease: 7) who suffer decreased muscle strength and endurance in addition to sensory and balance dysfunction due to paralysis or fracture, were studied. Each hot spring aquatic exercise session consisted of walking forward and backward, hip abduction, flexion, and extension, lunge, and squat, which lasted approximately 15 minutes. The loading level was set at a pulse of 77±11.2 → 84±13.5/minute, with a perceived exertion rate (modified Borg Scale) of 0.7±1.0 → 2.4±2.3. During the intervention period, conventional physical therapy was also performed on the patients in parallel. Measurement was performed 4 times, immediately, 10, 20, and 30 days after the initiation of intervention. Measurement items were the 6-minute walking distance (6MD) for an index of endurance, CS-30 score for an index of muscle strength, and hip flexor, extensor, and abductor, knee flexor and extensor, and ankle plantar and dorsiflexor strength using a hand-held dynamometer (HHD). Results: The 6MD and CS-30 scores improved 20 days after, and the hip flexor and extensor, knee flexor, and ankle plantar and dorsiflexor strength improved 30 days after the initiation of intervention. Those patients with higher ADL levels showed improvements markedly in 6MD score. Measurements conducted on some patients 60 days after the initiation showed improvements in the 6MD and CS-30 scores. Discussion: While it has been reported by other studies that the muscle activity level in the aquatic exercise is lower compared to that in the ordinary physical therapy, the results of CS-30, 6MD and HHD scores after the 30-day intervention in this study show the improvements at the muscle strength and endurance of each joint. This may be because the buoyancy and viscosity of water have contributed to the adjustment of the suitable exercise intensity level, which depends on each patient’s disability, the endurance and strength of the muscles involved in standing up and walking are improved. Based on these results, it is said that the intervention combining hot spring aquatic exercise and physical therapy should be continued for more than 20 days to improve the CS-30 score and 6MD, and more than 30 days to promote the muscle strength of each joint.

Objective: Our previous studies suggested that hot spring aquatic exercise may immediately improve the balance ability. As the long-term effects of such repeated exercise have not yet been examined, this present study aims to analyze them, focusing on the balance-related physical indexes. Methods: A total of 12 patients (the number of cerebrovascular disease patients: 5; the number of orthopedic disease patients: 7; mean age: 71.9±13.1; FIM: 117±7.5; and FBS score: 46.4±6.7), who had been treated with hot spring aquatic exercise therapy in our hospital were studied. Each patient showed decreased balance ability due to paralysis, sensory disturbance, or fracture. The measurement indexes were the ability to bend forward while sitting with their legs straight, Functional Balance Scale (FBS), Functional Reach Test (FRT) and Timed Up and Go (TUG) scores, sensory function was measured by the instrument (Semmes-Weinstein Monofilaments), and skin stiffness. Those were measured immediately, 10, 20, and 30 days after the initiation of the intervention.   Furthermore, indexes of eight patients out of those were measured 60 days after the initiation. Each exercise session consisted of walking forward and backward, hip abduction, flexion, and extension, lunge, and squat, which lasted approximately 15 minutes. The loading level was set at a pulse of 77±11.2 ≧ 84±13.5/minute, with a perceived exertion rate (modified Borg Scale) of 0.7±1.0 ≧ 2.4±2.3. Results: The ability to bend forward while sitting with their legs straight, TUG, FBS and sensory function, scores have improved significantly. Any significant improvements were not observed on FRT and skin stiffness. Discussion: The improvement of the sensory function was observed in patients with cerebrovascular disease. This would be because these therapies have the effect on the improvement of higher neuronal function. It is assumed that training efficiency in itself was improved, as the buoyancy and hydrostatic pressure assisted the patients to keep balance.   This exercise showed more effectiveness on the complicated balance indexes. On evaluation of each balance index, the TUG scores significantly improved significantly, while the FRT scores did not show any effects. As the balance-related indexes started to show improvements 30 days after the initiation, it should be recommended to continue this exercise for 30 days or more. Furthermore, in those who had not reached the maximum FBS score 30 days after the initiation, the improvement in scores was observed after 60 days. Further studies will be necessary to analyze these physical indexes, which showed improvements so that more effective exercises for each patient can be programmed taking the relevant balance-related physical indexes into account.

BACKGROUND: To examine changes in psychological distress prevalence among pregnant women in Miyagi Prefecture, which was directly affected by the Great East Japan Earthquake and tsunami, and compare it with the other, less damaged areas of Japan. METHODS: This study was conducted in conjunction with the Japan Environment and Children`s Study. We examined 76,152 pregnant women including 8270 in Miyagi Regional Center and 67,882 in 13 other regional centers from the all-birth fixed data of the Japan Environment and Children's Study. We then compared the prevalence and risk of distress in women in Miyagi Regional Center and women in the 13 regional centers for 3 years after the disaster. RESULTS: Women in the Miyagi Regional Center suffered more psychological distress than those in the 13 regional centers: OR 1.38 (95% CI, 1.03-1.87) to 1.92 (95% CI, 1.42-2.60). Additionally, women in the inland area had a consistently higher prevalence of psychological distress compared to those from the 13 regional centers: OR 1.67 (95% CI, 1.18-2.38) to 2.19 (95% CI, 1.60-2.99). CONCLUSIONS The lack of pre-disaster data in the Japan Environment and Children's Study made it impossible to compare the incidence of psychological distress before and after the March 2011 Great East Japan Earthquake. However, 3 years after the Great East Japan Earthquake, the prevalence of pregnant women with psychological distress did not improve in Miyagi Regional Center. Further, the prevalence of mental illness in inland areas was consistently higher than that in the 13 regional centers after the disaster.
