Expression of mitochondrial transcription factor A in endometrial carcinomas: clinicopathologic correlations and prognostic significance

Mitochondrial transcription factor A (mtTFA) is necessary for both transcription and maintenance of mitochondrial DNA. This study was conducted to elucidate the clinicopathologic and prognostic significance of mtTFA in patients with endometrial carcinoma. This study investigated the relationship between the immunohistochemical expression of mtTFA and various clinicopathological variables in 276 endometrial carcinomas, including 245 endometrioid adenocarcinomas and 31 nonendometrioid carcinomas (21 serous carcinomas and 10 clear cell adenocarcinomas). Both uni- and multivariate regression analyses were performed. The mtTFA labeling index of endometrioid adenocarcinomas ranged from 0% to 98%, with a median value of 32%, which was selected as the cut-off point for mtTFA expression. The mtTFA expression in endometrioid adenocarcinomas was significantly associated with the surgical stage, myometrial invasion, lymphovascular space invasion, cervical invasion, and lymph node metastasis. In contrast, no correlation between clinicopathologic variables and mtTFA expression was found in nonendometrioid carcinomas. Correlation analysis between mtTFA and p53 expression by using the Pearson test showed significant correlation in endometrioid adenocarcinomas (P = 0.007), but no significant correlation in nonendometrioid carcinomas (P = 0.947). A univariate survival analysis showed that the 10-year overall survival rate of the patients with mtTFA-positive endometrioid adenocarcinoma was significantly worse than that of patients with mtTFA-negative endometrioid adenocarcinoma (80.8% vs. 93.8%, P = 0.012). However, the multivariate analysis revealed that mtTFA expression in endometrioid adenocarcinomas was no independent prognostic factor. The positive mtTFA expression is a useful maker for progression of the tumors and the poor prognosis of the patients in endometrioid adenocarcinomas

Defibrillator Shocks and Their Impact on Objective and Subjective Patient Outcomes: Results from the Painfree SST Clinical Trial

BACKGROUND: The impact of ICD shock on device-measured activity and patient reported outcomes is unknown. OBJECTIVE: The purpose of this study was to analyze the acute and long-term effects of ICD shock on objective behavioral data (i.e., device-based physical activity) and subjective patient reported outcomes (e.g., quality of life and shock anxiety). METHODS: The PainFree SST clinical trial included 2,770 patients with a single or dual-chamber ICD, or cardiac resynchronization defibrillator (CRT-D) who were followed for 22 ± 9 months. Participants completed measures of quality of life (EuroQol 5-D [EQ5D]) and shock anxiety (Florida Shock Anxiety Scale [FSAS]) at baseline, bi-annual visits, and monthly for 6 months following an ICD shock. Daily physical activity data were obtained from a built-in device accelerometer. RESULTS: Average daily activity was 185.3 ± 119.4 minutes/day. Activity was significantly reduced after an ICD shock (p<0.0001) and recovered to a normal level after approximately 90 days. ICD shock was also associated with decreased quality of life (EQ5D Health Score) and increased EQ5D anxiety scores, but it did not impact mobility, self-care, activity, or pain. Similarly, shock anxiety (FSAS) increased in shocked patients and remained significantly elevated at 24 months, regardless of appropriate or inappropriate shock delivery. CONCLUSIONS: ICD shocks have a long-lasting, adverse impact on both objective, device-measured physical activity and subjective patient reported outcomes of quality of life and shock anxiety. Successful management of ICD patients requires attention to clinically relevant behavioral and psychological outcomes to expedite recovery and return to activities of daily living

Prevalence of and risk factors for postoperative complications after lower third molar extraction : A multicenter prospective observational study in Japan

Lower third molar extraction is the most common surgical treatment among routine dental and oral surgical procedures. while the surgical procedures for lower third molar extraction are well established, the difficulty of tooth extraction and the frequency of postoperative complications differ depending on the patient’s background. To establish a management protocol for the lower third molars, the prevalence of and risk factors for postoperative complications after lower third molar extraction were investigated in a large number of Japanese patients in a multicenter prospective study. During 6 consecutive months in 2020, 1826 lower third molar extractions were performed at the 20 participating institutions. The medical records of the patients were reviewed, and relevant data were extracted. The prevalence of and risk factors for postoperative complications were analyzed. The prevalence of postoperative complications after lower third molar extraction was 10.0%. Multivariate analysis indicated that age (≤32 vs >32, odds ratio [OR]: 1.428, 95% confidence interval [95% CI]: 1.040–1.962, P < .05), the radiographic anatomical relationship between the tooth roots and mandibular canal (overlapping of the roots and canal vs no close anatomical relationship between the roots and the superior border of the canal, OR: 2.078, 95% CI: 1.333–3.238, P < .01; overlapping of the roots and canal vs roots impinging on the superior border of the canal, OR: 1.599, 95% CI: 1.050–2.435, P < .05), and impaction depth according to the Pell and Gregory classification (position C vs position A, OR: 3.7622, 95% CI: 2.079–6.310, P < .001; position C vs position B, OR: 2.574, 95% CI: 1.574–4.210, P < .001) are significant independent risk factors for postoperative complications after lower third molar extraction. These results suggested that higher age and a deeply impacted tooth might be significant independent risk factors for postoperative complications after lower third molar extraction
