Is there a correlation between arthroscopic findings and the clinical signs and symptoms of patients with internal derangement of the temporomandibular joint? A prospective study

The aim of this study was to evaluate the correlation between clinical signs and symptoms of patients with internal derangement of the temporomandibular joint (TMJ) and arthroscopic findings. The study included a sample of 67 patients who underwent TMJ arthroscopy. The variables evaluated were the arthroscopic findings of synovitis, chondromalacia, adhesion, and roofing. The Spearman correlation index was used to correlate these findings with the clinical signs and symptoms of internal derangement of the TMJ, namely maximum mouth opening, pain (visual analogue scale, VAS), and the Wilkes classification. The mean age of the population was 36.16 years, and 85% were female. There was a correlation between pain and synovitis (P = 0.0029, r = 0.3508), between mouth opening limitation and the amount of adhesion (P = 0.0004, r = ?0.4084), and between Wilkes classification and the presence of chondromalacia and disc displacement (P = 0.001, r = 0.374 and P = 0.0045, r = ?0.3357, respectively). No correlation was found between age and the presence of chondromalacia (P = 0.3444, r = 0.1147). Patients who had worse pain symptoms had more advanced stages of synovitis, and the increased presence of adhesions was associated with limitations in mouth opening. Furthermore, those with more advanced Wilkes stages had greater disc displacement and more severe stages of chondromalacia.     

Differences in treatment and survival between elderly patients with thoracic esophageal cancer in metropolitan areas and other areas

To address the major issue of regional disparity in the treatment for elderly cancer patients in an aging society, we compared the treatment strategies used for elderly patients with thoracic esophageal cancer and their survival outcomes in metropolitan areas and other regions. Using the national database of hospital-based cancer registries in 2008-2011, patients aged 75 years or older who had been diagnosed with thoracic esophageal cancer were enrolled. We divided the patients into two groups: those treated in metropolitan areas (Tokyo, Kanagawa, Osaka, Aichi, Saitama, and Chiba prefectures) with populations of 6 million or more and those treated in other areas (the other 41 prefectures). Compared were patient backgrounds, treatment strategies, and survival curves at each cancer stage. In total, 1236 (24%) patients from metropolitan areas and 3830 (76%) patients from nonmetropolitan areas were enrolled. Patients in metropolitan areas were treated at more advanced stages. There was also a difference in treatment strategy. The 3-year survival rate among cStage I patients was better in metropolitan areas (71.6% vs. 63.7%), and this finding mainly reflected the survival difference between patients treated with radiotherapy alone. For cStage II-IV patients, there were no differences. Multivariable Cox proportional hazard analysis including interaction terms between treatment areas, cStage, and the first-line treatments revealed that treatments in the metropolitan areas were significantly associated with better survival among patients treated with radiotherapy alone for cStage I cancer. Treatment strategies for elderly patients with thoracic esophageal cancer and its survival outcomes differed between metropolitan areas and other regions.     

Optimal cut-off value of preprocedural geriatric nutritional risk index for predicting the clinical outcomes of patients undergoing endovascular revascularization for peripheral artery disease

BackgroundMalnutrition measured by the geriatric nutritional risk index (GNRI) was reported to be associated with poor prognosis for patients with peripheral artery disease (PAD). However, the optimal cut-off value of preprocedural GNRI for critical limb ischemia (CLI) and intermittent claudication (IC) is unknown. We aimed to determine its optimal cut-off value for CLI or IC patients requiring endovascular revascularization.MethodsWe explored data of 2246 patients (CLI: n = 1061, IC: n = 1185) registered in the Tokyo-taMA peripheral vascular intervention research COmraDE (TOMA-CODE) registry, which prospectively enrolled consecutive PAD patients who underwent endovascular revascularization in 34 hospitals in Japan from August 2014 to August 2016. The optimal cut-off values of GNRI were assessed by the survival classification and regression tree (CART) analyses, and the survival curve analyses for major adverse cardiovascular and limb events (MACLEs) were performed for these cut-off values.ResultsIn addition to the first cut-off value of 96.2 in CLI and 85.6 in IC, the survival CART provided an additional cut-off value of 78.2 in CLI and 106.0 in IC for further risk stratification. The survival curve was significantly stratified by the GNRI-based malnutrition status in both CLI [high risk: 47.7% (51/107), moderate: 30.1% (118/392), and low: 10.2% (53/520), log–rank p < 0.001] and IC [high risk: 14.3% (7/49), moderate: 4.5% (29/646), and low: 0.5% (2/407), log–rank p < 0.001]. The multivariate Cox-proportional hazard analysis showed that a higher GNRI was significantly associated with a better outcome in both CLI [hazard ratio (HR) per 1-point increase: 0.97, 95% CI: 0.96–0.98, p < 0.001] and IC (HR: 0.94, 95% CI: 0.91–0.97, p < 0.001).ConclusionsPreprocedural nutritional status significantly stratified future events in patients with PAD. Given that the optimal cut-off value of GNRI in CLI was almost 10-points lower than that of IC, using a disease-specific cut-off value is important for risk stratification.     

J‐curve association between alcohol intake and varicose veins in Japan: The Shimane CoHRE Study

The effect of alcohol intake on varicose veins (VV) has not been determined by its consumption level. The aim of this study was to investigate the association between alcohol intake and VV in an elderly general population. Using a cross‐sectional approach, the Shimane CoHRE Study data, comprising a total of 1060 participants, were analyzed. By multivariate regression analysis adjusted with basic characteristics, past work history, lifestyle‐related factors and medical history, compared with non‐drinkers, mild drinkers (<20.0 g/day) showed a significantly lower adjusted odds ratio (aOR) of VV (aOR = 0.64, P = 0.036). In a similar way, regular drinkers (1–5 days/week) showed a significantly lower aOR of VV when compared with occasional drinkers (aOR = 0.57, P = 0.032). VV and alcohol intake showed J‐curve relationships. In a stratified analysis by alcohol consumption levels, the association of smoking and VV were also observed in moderate to heavy drinkers and habitual drinkers. These findings can provide better understanding of pathophysiological mechanism and be used for evidence‐based patient education.
