Background Although delayed union or pseudoarthrosis after lumbar arthrodesis has been recognized as a major radiographic complication, little has been known about the effect of fusion status on the patient’s quality-of-life (QOL) outcome. The purpose of this study was to investigate the effects of fusion status after posterior lumbar interbody fusion (PLIF) on QOL outcomes by using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ).Methods Among 100 patients who underwent single level PLIF for spinal canal stenosis, 29 who had not achieved fusion (incomplete fusion group) and 29 age- and sex ratio-matched patients who had achieved fusion (fusion group) 6 months after surgery were enrolled. Overall clinical evaluation was performed before and 6 months after surgery: the physician determined the Japanese Orthopaedic Association Score for Low Back Pain (JOA score); the JOABPEQ and visual analogue scale (VAS) values were collected. The recovery rate of the JOA score, changes in all JOABPEQ subdomain scores and in the VAS values were calculated. All variables were compared between the groups.Results The preoperative JOA scores, JOABPEQ scores of all subdomains, and VAS values of all categories did not differ between the groups. The recovery rate was higher in the fusion group than the incomplete fusion group (p = 0.0185). The changes in the JOABPEQ scores for walking ability and social life function were significantly greater in the fusion group than the incomplete fusion group (walking ability, p = 0.0172; social life function, p = 0.0191). The postoperative VAS values and changes in the VAS values for all categories did not differ between the groups.Conclusions Incomplete fusion after PLIF correlated with poor improvement in walking ability and social life function. Therefore, the achievement of fusion after PLIF is essential to obtain better patient QOL outcomes. 相似文献

l-lactic acid)30 (AB-type), which accumulates in solid
tumors through the enhanced permeability and retention (EPR) effect.
However, lactosome on multiple administrations changed its pharmacokinetics
from accumulation in tumors to liver due to the production of antilactosome
IgM, which was triggered by the first administration. This phenomenon
is called the accelerated blood clearance (ABC). In order to reduce
the production of antilactosome IgM, a novel nanoparticle composed
of (poly(sarcosine)23)3-block-poly(l-lactic acid)30 (A3B-type)
was prepared. The A3B-type lactosome at the second administration
showed an in vivo disposition similar to that at
the first administration due to suppression of antibody production.
This study involving the AB- and A3B-type lactosomes, with
variation of conditions, revealed that the high local density of poly(sarcosine)
chains of the A3B-type lactosome should relate to the prevention
of a polymeric micelle from interacting B-cell receptors. 相似文献

Patients with advanced bladder cancer are generally treated with a combination of chemotherapeutics, including gemcitabine, but the effect is limited due to acquisition of drug resistance. Thus, in this study, we investigated the mechanism of gemcitabine resistance. First, gemcitabine‐resistant cells were established and resistance confirmed in vitro and in vivo. Small RNA sequencing analyses were performed to search for miRNAs involved in gemcitabine resistance. miR‐99a‐5p, selected as a candidate miRNA, was downregulated compared to its parental cells. In gain‐of‐function studies, miR‐99a‐5p inhibited cell viabilities and restored sensitivity to gemcitabine. RNA sequencing analysis was performed to find the target gene of miR‐99a‐5p. SMARCD1 was selected as a candidate gene. Dual‐luciferase reporter assays showed that miR‐99a‐5p directly regulated SMARCD1. Loss‐of‐function studies conducted with si‐RNAs revealed suppression of cell functions and restoration of gemcitabine sensitivity. miR‐99a‐5p overexpression and SMARCD1 knockdown also suppressed gemcitabine‐resistant cells in vivo. Furthermore, β‐galactosidase staining showed that miR‐99a‐5p induction and SMARCD1 suppression contributed to cellular senescence. In summary, tumor‐suppressive miR‐99a‐5p induced cellular senescence in gemcitabine‐resistant bladder cancer cells by targeting SMARCD1. 相似文献

Epidemiological evidence on the effects of a long‐term low‐carbohydrate diet (LCD) on cancer incidence remains sparse. We investigate the association between LCD and the risk of overall and specific cancer site incidence in a Japanese population‐based prospective cohort study among 90 171 participants aged 45‐74. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During a median 17.0 y of follow‐up, we identified 15 203 cancer cases. A higher overall LCD score was associated with increased overall cancer risk (HR = 1.08 [CI: 1.02‐1.14], P‐trend = .012), while it was associated with decreased gastric cancer (GC) risk (0.81 [0.71‐0.93], P‐trend = .006). A higher animal‐based LCD score was associated with higher risk of overall cancer (1.08 [1.02‐1.14], P‐trend = .003), colorectal cancer (CRC) (1.11 [0.98‐1.25], P‐trend = .018), rectal cancer (RC) (1.24 [1.00‐1.54], P‐trend = .025), lung cancer (LC) (1.16 [1.00‐1.34], P‐trend = .042), and lower risk of GC (0.90 [0.79‐1.01], P‐trend = .033). Furthermore, we found that plant‐based LCD score was related to lower GC incidence (0.87 [0.77‐0.99], P‐trend = .031). Additionally, adjusted for plant fat intake amplified the adverse associations (overall cancer: 1.08 [1.02‐1.14] vs. 1.11 [1.05‐1.18]; CRC: 1.08 [0.95‐1.22] vs. 1.13 [0.99‐1.30]; LC: 1.14 [0.98‐1.33] vs. 1.19 [1.01‐1.41]). We conclude that LCD enriching with animal products was associated with increased overall cancer, CRC, and LC incidence. These adverse associations could be attenuated by plant fat consumption. LCD reduces the risk of developing GC. Long‐term adherence to LCD without paying attention to the balance between animal and plant food source consumption might cause adverse overall cancer incidence consequences. 相似文献

Family history (FH) of cancer is an important factor of increased risk of several cancers. Although the association between FH of cancer and concordant cancer risk has been reported in many previous epidemiological studies, no comprehensive prospective study with adjustment for lifestyle habits has evaluated the association of FH of cancer and concordant cancer risk. We investigated the association between FH of cancer and concordant cancer risk in a Japanese population-based prospective study, initiated in 1990 for cohort I and in 1993 for cohort II. We analyzed data on 103,707 eligible subjects without a history of cancer who responded to a self-administered questionnaire including FH of cancer at baseline. Study subjects were followed through 2012 and analyzed using multivariable-adjusted Cox proportional hazards regression models. During 1,802,581 person-years of follow-up, a total of 16,336 newly diagnosed cancers were identified. Any site (Hazard ratios = 1.11 (95% confidence interval = 1.07–1.15]), esophagus (2.11 [1.00–4.45]), stomach (1.36 [1.19–1.55]), liver (1.69 [1.10–2.61]), pancreas (2.63 [1.45–4.79]), lung (1.51 [1.14–2.00]), uterus (1.93 [1.06–3.51]) and bladder cancers (6.06 [2.49–14.74]) with FH of the concordant cancer were associated with an increased risk compared to those without FH. Our findings suggest that having FH of cancer is associated with an increased risk of several concordant cancer incidences in an Asian population. Enquiring about FH of several types of cancer may be important in identifying groups at high-risk of those cancers. 相似文献

Here, we report a case of traumatic pulmonary pseudocysts (TPPs) coinciding with vertebral fracture. Traumatic pulmonary pseudocysts (TPPs) are rare complications of blunt chest trauma. These clinical images of CT, presenting here, seemed to be valuable because they show the process of pseudocyst formation. 相似文献

Background Progression of ossification of the posterior longitudinal ligament in patients may lead to serious neurological deterioration.
A government-funded study group established a manual method of measurement on plain radiographs to detect progression of the
ossified lesion. However, this method did not gain wide acceptance because it was time-consuming and complicated, for which
drawings of many lines and points are required. We have applied a computer-assisted measurement system to this task and have
evaluated inter- and intraexaminer reliability, showing that it is quicker to use and more accurate than the manual method.
Methods Eight board-certified spine surgeons, acting as the examiners, measured the sizes of the ossified lesions on nine lateral
cervical spine radiographs using the computer-assisted measurement system. Following insertion of digitized radiographic image
data into a computer, the corners of the vertebral bodies on the displayed images are marked by the examiners, and the software
automatically sets reference lines and points. The examiners identify upper, lower, and posterior margins of the ossified
lesions, and the software calculates the dimensions of the ossified lesions. Data obtained from eight examiners for length
and thickness underwent rigorous statistical analysis by calculating the intraclass correlation coefficients with 95% confidence
intervals (CIs) to determine interexaminer reliability and Pearson's correlation coefficients between the two measurements
by the same examiner to determine intraexaminer reliability.
Results The intraclass correlation coefficients were 0.927 and 0.968 with 95% CIs of 0.883–0.955 and 0.956–0.978 for measurements
of length and thickness, respectively, of the ossified lesions. The Pearson's correlation coefficients for the two measurements
by the same examiners were 0.943–0.985 for length and 0.957–0.991 for thickness.
Conclusions The inter- and intraexaminer reliability using this measurement system was excellent. The method can detect progression of
ossification of the posterior longitudinal ligament (OPLL) on plain radiographs with high precision and could become a standard
method for measuring the size of OPLL. 相似文献

We present a 70-year-old man who was referred for surgery with uncontrollable hypoglycemia. Ultrasonography and abdominal contrast computed tomography revealed a hypervascular tumor of 1 cm in diameter in the pancreatic tail. With a diagnosis of insulinoma, we performed a distal pancreatectomy. The patient showed a good postoperative course without any complications. The patient’s early morning fasting hypoglycemia disappeared. The respective levels of C-peptide and insulin dropped from 14.9 ng/mL and 4860 μIU/mL preoperatively to 5.3 ng/mL and 553 μIU/mL after surgery. A histopathological examination demonstrated that the tumor was a pancreatic neuroendocrine tumor, grade 1. Immunostaining was negative for insulin and positive for CD56, chromogranin A, synaptophysin and glucagon. These findings suggested that the tumor was clinically an insulinoma but histopathologically a glucagonoma. Among all insulinoma cases reported between 1985 and 2010, only 5 cases were associated with independent glucagonoma. In this report, we characterize and discuss this rare type of insulinoma by describing the case we experienced in detail. 相似文献
