A 54-year-old woman presenting with anterior alveolar ridge resorption was submitted to a connective tissue graft (CTG) for esthetic improvement before rehabilitation with a fixed partial denture. Palate-harvested connective tissue was used as a graft after extra-oral removal of the epithelium. Unexpectedly, complete wound healing was not observed. Moreover, 6 months post-surgery, a white discharge was detected at the grafted site. The adjacent tooth showing a root fracture was initially associated with the symptoms and was then extracted. Concomitantly, the unhealed tissue at the grafted site was also excised, leading to temporary symptom resolution. However, the white discharge reappeared after 2 months. The excision area was expanded to remove the grafted tissue entirely, and the wound was completely healed. Since the alveolar ridge resorption had become larger compared to the preoperative condition, the patient was subjected to a second CTG, now using a connective tissue harvested from the palate by a single incision technique. The wound healed uneventfully, and the final prosthesis was delivered 6 months after soft tissu e stabilization. The patient has been followed-up for more than 28 months without any recurrence of white discharge.

Histopathological and cytological examination detected keratinized epithelial tissues and cells, respectively, in excised tissues and white discharge specimens. Consequently, a possible relationship between white discharge and residual epithelium in the harvested graft was strongly suspected.

The present study was performed to investigate the specific role of RFC4 in hepatocellular carcinoma (HCC) and the underlying molecular mechanism. Public datasets including TCGA and GTEx were applied to explore the expression of RFC4 in HCC and its association with HCC prognosis. The results of bioinformatics analysis showed that RFC4 was overexpressed in HCC tissues compared with noncancerous tissues and significantly correlated with poor prognosis for HCC. Through immunohistochemistry, the association between RFC4 expression and clinical-pathological features of HCC patients was evaluated. Western blots were applied to investigate relative protein expression. Then in vivo and in vitro experiments were performed to explore the function of RFC4 in HCC tumor cells. The present results suggest that high level expression of RFC4 is associated with tumor size. In addition, RFC4 knockdown suppressed the cell proliferation and sphere formation of hepatoma cells in vitro. Moreover, silencing of RFC4 significantly decreased the growth of tumors in a xenograft tumor model. In conclusion, our study indicates that RFC4 is a potential prognostic predictor associated with poor outcomes for HCC patients. Furthermore, knocking down RFC4 could significantly inhibit tumor progression both in vitro and in vivo. Therefore, the present study can shed new light on the understanding of molecular mechanisms of HCC and may provide molecular targets and diagnostic biomarkers for the treatment of HCC.

This study evaluated the long-term outcomes for up to 20 years after On-X mechanical valve implantation in the left side of the heart.Methods and ResultsBetween 1999 and 2015, 861 patients (mean age=51.6±10.9 years) who underwent prosthetic valve replacement using the On-X valve in the aortic or mitral position were enrolled (aortic=344, mitral=325, double=192). The mean clinical follow-up duration was 10.5±5.3 (median 10.9) years. Operative mortality occurred in 26 patients (3.0%), and linearized late cardiac mortality was 0.9%/patient-year without an intergroup difference. Linearized thromboembolism, bleeding, prosthetic valve endocarditis, non-structural valve deterioration (NSVD), and reoperation rates were 0.8%/patient-year, 0.6%/patient-year, 0.2%/patient-year, 0.5%/patient-year, and 0.5%/patient-year, respectively. Prosthetic valve endocarditis was more frequent after double valve replacement than after aortic or mitral valve replacement (P=0.008 and 0.005, respectively). NSVD and reoperation rates were significantly lower aortic valve replacement than after mitral or double valve replacement (P=0.001 and 0.002, P=0.001 and <0.001, respectively). Valve replacement in the mitral position was the only risk factor for NSVD (hazard ratio [95% confidence interval]=5.247 [1.608-17.116], P=0.006).

On-X valve implantation in the left side heart had favorable clinical outcomes with acceptable early and late mortality and a low incidence of prosthetic valve-related complications. Particularly in the aortic position, the On-X valve had better long-term non-structural durability.

This case report presents an 86-year-old woman with rheumatoid arthritis who experienced rebound-associated spontaneous clinical vertebral fractures at 9 months after denosumab discontinuation. Following 5-year bisphosphonate treatment, the patient had 9 injections of 60-mg denosumab every 6 months. Because of tooth extraction, denosumab treatment was discontinued, and raloxifene was administered. At 9 months after the last denosumab injection, the patient experienced severe low back pain. Magnetic resonance imaging (MRI) and radiograph demonstrated clinical fracture at the fourth lumbar vertebra. MRI performed at 3 months after first fracture showed two additional fractures at the second and third lumbar vertebrae. Teriparatide was administered for management of rebound-associated spontaneous clinical, multiple vertebral fractures. Teriparatide was effective for accelerating the fracture healing and suppressing the occurrence of new fractures. However, 2-year treatment of teriparatide did not have suppressive effect of rebound in bone turnover and general bone loss. This case suggested that teriparatide was effective for suppression of new rebound-associated spontaneous clinical vertebral fractures, but not effective in prevention of general bone loss after denosumab discontinuation.Whether trastuzumab use beyond disease progression is beneficial in second-line treatment for patients with unresectable human epidermal growth factor receptor 2 (HER2)-positive gastric cancer remains to be elucidated. We conducted this phase II study to assess whether trastuzumab plus docetaxel was effective for patients with previously treated advanced HER2-positive gastric cancer. This trial was a single-arm, open-label, multicenter, phase II study, conducted by Tohoku Clinical Oncology Research and Education Society (T-CORE). Patients aged 20 years or older who had advanced HER2-positive gastric cancer and were refractory to trastuzumab, fluoropyrimidine, and cisplatin were enrolled. Patients were treated with 6 mg/kg trastuzumab and 60 mg/m2 docetaxel every 3 weeks. The primary endpoint was the overall response rate. The threshold overall response rate was estimated to be at 15%. Secondary endpoints were progression-free survival, 6-month survival rate, overall survival, and toxicities. A total of 27 patients were enrolled from 7 hospitals. The median age was 67 years. Partial response was seen in 3 patients among the 26 evaluated patients. The overall response rate was at 11.5% (90% confidence interval 1.2%-21.8%). BI-1347 chemical structure The median progression-free survival was 3.2 months, the 6-month survival rate was 85%, and the median overall survival was 11.6 months. Febrile neutropenia was observed in 14.8%. The most frequently observed grade 3 non-hematologic toxicity was anorexia (14.8%). The primary endpoint was not achieved. The results support a current consensus that the continuation of trastuzumab in second-line therapy for gastric cancer is not a recommended option.

A prospective cohort study in a Japanese urban general population was performed to investigate whether triglyceride (TG) and its related indices were associated with the risk for the incidence of ischemic cardiovascular disease (CVD) after the adjustment for low-density lipoprotein cholesterol (LDL-C) in Asian community dwellers.

A 15.1-year prospective cohort study was performed in 6,684 Japanese community dwellers aged 30-79 years without a history of CVD and whose fasting TG levels were ＜400 mg/dL. After adjusting for covariates, including LDL-C, the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of the deciles (D) of TG and those of 1-standard deviation (SD) increment of log-transformed TG (1-SD of TG) according to LDL-C level (≥ 140 and ＜140 mg/dL) for ischemic CVD incidence were estimated. The multivariable-adjusted HRs and 95%CIs of the quintiles (Q) of TG, TG/HDL-C, and the cardiometabolic index (CMI) for ischemic CVD were also estimated.

In 101,230 person-years, 464 ischemic CVD cases occurred. For D10 of TG, the HR (95%CI) was 1.56 (1.05-2.32), and for 1-SD of TG, it was 1.30 (1.00-1.70) in participants with LDL-C ＜140 mg/dL and 1.07 (0.77-1.50) in those with LDL-C ≥ 140 mg/dL. For Q5 of the CMI, the multivariable-adjusted HR was higher than those of TG and TG/HDL-C.

Fasting TG was an independent predictor for ischemic CVD incidence after adjusting for LDL-C in Japanese community dwellers with TG ＜400 mg/dL. Among TG, TG/HDL-C, and the CMI, the CMI could be the most powerful predictor for ischemic CVD.

Impact of immeasurable time bias (IMTB) is yet to be examined in self-controlled designs.

We conducted case-crossover, case-time-control, and case-case-time-control analyses using Korea's healthcare database. Two empirical examples among elderly patients were used 1) benzodiazepines-hip fracture; 2) benzodiazepines-mortality. For cases, the date of hip fracture diagnosis or death was defined as the index date, and the inherited date of their matched cases for controls or future cases. Exposure was assessed in the 1-30 day (hazard) and 61-90 day (control) windows preceding the index date. A non-missing exposure setting included in- and outpatient prescriptions and the pseudo-outpatient setting included only the outpatients. Conditional logistic regression was done to estimate odds ratio (OR) with 95% confidence intervals (CI), where the relative difference in OR among the two settings was calculated to quantify the IMTB.

The IMTB had negligible impacts in the hip fracture example in the case-crossover (non-missing exposure setting OR 1.
