Masked obesity is the presence of obesity based on percent body fat (%BF) when the body mass index (BMI) shows an absence of obesity. To examine the relationship between masked obesity and arteriosclerosis risk factors, we compared both serum lipid levels and the prevalence of hyperlipidemia in male and female high school freshmen with and without masked obesity. Subjects consisted of 403 male and 326 female high school students aged 15∼16 years. Of these, 34(8.4%) males and 36(11.0%) females had masked obesity, defined as 17≤BMI<23.60 and %BF≥25% in males, and 17≤BMI<24.17 and %BF≥30% in females, while the remaining 300 males and 246 females were not obese, having 17≤BMI<23.60 and %BF<25% and 17≤BMI<24.17 and %BF<30%, respectively. For both sexes, serum total-cholesterol (TC), low-density lipoprotein cholesterol (LDLC), triglycerides and the arteriosclerotic index (AI) were significantly higher (p<0.05∼0.01) in those with masked obesity. And many of the subjects with masked obesity had abnormal levels of TC, LDLC and AI, compared with those who were not obese (p<0.05∼0.01). Additionally, we compared both serum lipid levels and the prevalence of hyperlipidemia between subjects with masked obesity and control groups with the same BMI values. As a result, subjects with masked obesity had high serum lipid levels and a prevalence of hyperlipidemia. These results support the existence of masked obesity and suggest that masked obesity is associated with increased serum lipid levels, and thus could be a risk factor for arteriosclerosis in male and female high school freshmen.

This study aimed to examine the effects of an 8-week physical activity program, which mainly comprised home-based bench-stepping exercise training at the intensity of lactate threshold (LT), on mental health (MH), health-related quality of life (HRQOL), and physical fitness in Japanese returnees from China. Thirty Japanese returnees (63 ± 9 y) participated in the exercise program. Another six subjects were enrolled as the control group. The subjects performed 212 ± 57 min of training, and their daily step counts were increased. Aerobic capacity (LT: 4.5 ± 0.8 vs. 5.5 ± 1.1 METs), lower limb strength (30-s chair stand test [CS-30]: 19.1 ± 5.5 vs. 21.3 ± 5.1 times), and sit-and-reach flexibility (sitting-posture body anteflexion: 36.1 ± 9.4 vs. 39.0 ± 8.4 cm) were significantly increased after the intervention compared with before the intervention. Furthermore, MH, as assessed by the total score of the GHQ-28 (3.4 ± 4.4 vs. 0.3 ± 0.8 points), and the mental component score (MCS) of HRQOL, as evaluated by the SF-36v2 (55.1 ± 11.4 vs. 58.5 ± 10.0), were significantly changed in a positive manner. However, a two-way repeated measures ANOVA (group × period) showed significant interactions for LT and MCS (p<0.05), and a tendency for interactions of CS-30 (p=0.063) and the total score of the GHQ-28 (p=0.098). These results indicate that this bench-stepping exercise program could become a useful health support program for improving physical fitness, as well as MH and HRQOL, in Japanese returnees.

BACKGROUND: Although non-thyroidal illness syndrome (NTIS) is considered a negative prognostic factor, the alterations in free triiodothyronine (fT3) levels in trauma patients requiring massive transfusion have not been reported. METHODS: A prospective observational study comparing 2 groups of trauma patients was conducted. Group M comprised trauma patients requiring massive transfusions (>10 units of packed red blood cells) within 24 hours of emergency admission. Group C comprised patients with an injury severity score >9 but not requiring massive transfusions. Levels of fT3, free thyroxine (fT4), and thyroid-stimulating hormone (TSH) were evaluated on admission and on days 1, 2, and 7 after admission. The clinical backgrounds and variables measured including total transfusion amounts were compared and the inter-group prognosis was evaluated. Results are presented as mean±standard deviation. RESULTS: Nineteen patients were enrolled in each group. In both groups, 32 were men, and the mean age was 50±24 years. In group C one patient died from respiratory failure. The initial fT3 levels in group M (1.95±0.37 pg/mL) were significantly lower than those in group C (2.49±0.72 pg/mL;P<0.01) and remained low until 1 week after admission. Initial inter-group fT4 and TSH levels were not significantly different. TSH levels at 1 week (1.99±1.64 μIU/mL) were higher than at admission (1.48±0.5 μIU/mL) in group C (P<0.05). CONCLUSION: Typical NTIS was observed in trauma patients requiring massive transfusions. When initial resuscitation achieved circulatory stabilization, prognosis was not strongly associated with NTIS.

Methods:
This study included 99 men (mean age, 74.9 years; range, 28–93 years) who visited Qiball Clinic for BMD and body composition examinations. The osteoporosis group consisted of 24 patients (mean age, 72.5 years; range, 44–92 years), and the control group consisted of 75 individuals (mean age, 74.9 years; range, 28–93 years). Whole-body skeletal muscle mass was measured using a bioelectrical impedance analyzer. BMD was measured by dual X-ray absorptiometry. Skin autofluorescence (SAF), a marker of dermal AGE accumulation, was measured using a spectroscope. Osteoporosis was defined as a bone density T score of –2.5 or less. Physical findings, skeletal muscle mass, BMD, grip strength, and SAF were compared between the osteoporosis and control groups.
Results:
The osteoporosis group had significantly lower trunk muscle mass (23.1 kg vs. 24.9 kg), lower leg muscle mass (14.4 kg vs. 13.0 kg), and skeletal mass index (7.1 kg/m2 vs. 6.7 kg/m2) than the control group (all p<0.05). Lower limb muscle mass was identified as a risk factor for osteoporosis in men (odds ratio, 0.64; p=0.03).
Conclusions
Conservative treatment of osteoporosis in men will require an effective approach that facilitates the maintenance or strengthening of skeletal muscle mass, including exercise therapy with a focus on lower extremities and nutritional supplementation.

PURPOSE: Opioids improve pain from knee and hip osteoarthritis (OA) and decrease the functional impairment of patients. However, there is a possibility that opioids induce analgesia and suppress the physiological pain of OA in patients, thereby inducing the progression of OA changes in these patients. The purpose of the current study was to investigate the possibility of progressive changes in OA among patients using opioids. MATERIALS AND METHODS: Two hundred knee or hip OA patients were evaluated in the current prospective, randomized, active-controlled study. Patients were randomized 1:1:1 into three parallel treatment groups: loxoprofen, tramadol/acetaminophen, and transdermal fentanyl groups. Medication was administered for 12 weeks. Pain scores and progressive OA changes on X-ray films were evaluated. RESULTS: Overall, pain relief was obtained by all three groups. Most patients did not show progressive OA changes; however, 3 patients in the transdermal fentanyl group showed progressive OA changes during the 12 weeks of treatment. These 3 patients used significantly higher doses than others in the transdermal fentanyl group. Additionally, the average pain score for these 3 patients was significantly lower than the average pain score for the other patients in the transdermal fentanyl group. CONCLUSION: Fentanyl may induce progressive changes in knee or hip OA during a relatively short period, compared with oral Non-Steroidal Anti-Inflammatory Drugs or tramadol.

STUDY DESIGN: Retrospective case series. PURPOSE: To examine the most effective duration of teriparatide use for spinal fusion in women with postmenopausal osteoporosis. OVERVIEW OF LITERATURE: We reported that daily subcutaneous injection of teriparatide (parathyroid hormone) significantly improved bone union after instrumented lumbar posterolateral fusion (PLF) in women with postmenopausal osteoporosis when compared with oral administration of bisphosphonate. However, the most effective duration of teriparatide use for spinal fusion has not been explored. METHODS: Forty-five women with osteoporosis diagnosed with degenerative spondylolisthesis from one of the three treatment groups were evaluated based on: short-duration treatment (average, 5.5 months; n=15; daily subcutaneous injection of 20 microg teriparatide), long-duration treatment (average, 13.0 months; n=15; daily subcutaneous injection of 20 microg teriparatide), and bisphosphonate treatment (average, 13.0 months; n=15; weekly oral administration of 17.5 mg risedronate). All patients underwent PLF with a local bone graft. Fusion rate and duration of bone union were evaluated 1.5 years after surgery. RESULTS: Bone union rate and average duration for bone union were 92% and 7.5 months in the long-duration treatment group, 80% and 8.5 months in the short-duration treatment group, and 70% and 10.0 months in the bisphosphonate treatment group, respectively. Results of bone union rate and average duration for bone union in the teriparatide treatment groups were significantly superior to those in the bisphosphonate treatment group (p<0.05); whereas, significantly superior results were observed in long-duration treatment group when compared with short-duration treatment group (p<0.05). CONCLUSIONS: Daily injection of teriparatide for bone union was more effective than oral administration of bisphosphonate. Furthermore, a longer period of teriparatide treatment for bone union was more effective than a shorter period of same treatment.

PURPOSE: Pain from vertebral or femoral neck fractures is a particularly important problem in clinical orthopaedics. Transient receptor potential vanilloid 1 (TRPV1) is a ligand-gated nonselective cation channel, and there are recent reports on an association between bone pain and TRPV1. However, an increase in TRPV1 activity has not been reported following femoral fracture. MATERIALS AND METHODS: We applied a neurotracer [Fluoro-gold (FG)] onto femur to detect dorsal root ganglia (DRGs) innervating the cortex of the femur in 30 Sprague Dawley rats. Seven days after application, a closed mid-diaphyseal fracture of the femur was performed. FG labeled TRPV1-immunoreactive (ir) DRGs innervating the femur were examined in nonfractured controls, and 3 days, 1 week, 2 weeks, and 4 weeks after fracture. We evaluated bone healing of the femur and compared the ratio of TRPV1-ir DRG neurons innervating the femur at the time points. RESULTS: Four weeks after fracture, complete bone union was observed. There was no significant difference in the ratio of FG labeled DRG neurons to total DRG neurons at each time point. The percentages of TRPV1-ir neurons in DRGs innervating the femur at 3 days and 1 week after fracture were significantly higher than those in control, 2 weeks, and 4 weeks after fracture (p<0.05). CONCLUSION: Fracture induced an increase of TRPV1-ir neurons in DRGs innervating the fractured femur within 3 days, and decreased during bone healing over 4 weeks. These findings show that TRPV1 may play a role in sensory sensation of bone fracture pain.

PURPOSE: Osteoarthritic pain is largely considered to be inflammatory pain. Sensory nerve fibers innervating the knee have been shown to be significantly damaged in rat models of knee osteoarthritis (OA) in which the subchondral bone junction is destroyed, and this induces neuropathic pain (NP). Pregabalin was developed as a pain killer for NP; however, there are no reports on pregabalin use in OA patients. The purpose of this study was to investigate the efficacy of pregabalin for pain in OA patients. MATERIALS AND METHODS: Eighty-nine knee OA patients were evaluated in this randomized prospective study. Patients were divided into meloxicam, pregabalin, and meloxicam+pregabalin groups. Pain scores were evaluated before and 4 weeks after drug application using a visual analogue scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Pain scales among groups were compared using a Kruskal-Wallis test. RESULTS: Before drug application, there was no significant difference in VAS and WOMAC scores among the three groups (p>0.05). Significant pain relief was seen in the meloxicam+pregabalin group in VAS at 1, 2, and 4 weeks, and WOMAC score at 4 weeks, compared with the other groups (p<0.05). No significant pain relief was seen in the meloxicam only group in VAS during 4 weeks and WOMAC score at 4 weeks compared with the pregabalin only group (p>0.05). CONCLUSION: Meloxicam+pregabalin was effective for pain in OA patients. This finding suggests that OA pain is a combination of inflammatory and NP.

PURPOSE: Bupivacaine is commonly used for the treatment of back pain and the diagnosis of its origin. Nonunion is sometimes observed after spinal fusion surgery; however, whether the nonunion causes pain is controversial. In the current study, we aimed to detect painful nonunion by injecting bupivacaine into the disc space of patients with nonunion after anterior lumbar interbody fusion (ALIF) surgery for discogenic low back pain. MATERIALS AND METHODS: From 52 patients with low back pain, we selected 42 who showed disc degeneration at only one level (L4-L5 or L5-S1) on magnetic resonance imaging and were diagnosed by pain provocation on discography and pain relief by discoblock (the injection of bupivacaine). They underwent ALIF surgery. If the patients showed low back pain and nonunion 2 years after surgery, we injected bupivacaine into the nonunion disc space. Patients showing pain relief after injection of bupivacaine underwent additional posterior fixation using pedicle screws. These patients were followed up 2 years after the revision surgery. RESULTS: Of the 42 patient subjects, 7 showed nonunion. Four of them did not show low back pain; whereas 3 showed moderate or severe low back pain. These 3 patients showed pain reduction after injection of bupivacaine into their nonunion disc space and underwent additional posterior fixation. They showed bony union and pain relief 2 years after the revision surgery. CONCLUSION: Injection of bupivacaine into the nonunion disc space after ALIF surgery for discogenic low back pain is useful for diagnosis of the origin of pain.
