Association of residual gastric acid secretion with persistent symptoms in gastroesophageal reflux disease patients receiving standard-dose proton pump inhibitor therapy.

BACKGROUND: Although a third of gastroesophageal reflux disease (GERD) patients are refractory to proton pump inhibitor (PPI) therapy, the underlying mechanism of the refractoriness remains unclear. We compared the level of gastric acid suppression during PPI treatment between responders and non-responders by directly measuring gastric acid secretion in GERD patients taking PPIs. METHODS: Seventy-five consecutive patients receiving standard-dose PPI therapy for GERD were prospectively recruited, irrespective of persistent GERD symptoms. They were asked about their GERD symptoms using a validated questionnaire, and simultaneously underwent both a routine endoscopic examination and a gastric acid secretory testing using an endoscopic gastrin test. Associations between residual gastric acid secretion during PPI treatment and persistent GERD symptoms were analyzed by a logistic regression analysis. RESULTS: Overall, 26 of 75 (34.7%) patients were judged to be positive for persistent GERD symptoms. The patients with and without persistent symptoms showed similar gastric acid secretion levels (1.3 [1.3] mEq/10 min vs. 1.4 [2.0] mEq/10 min). Sufficient gastric acid suppression, defined as < 0.6, was not significantly associated with persistent GERD symptoms (odds ratio 1.1, 95% confidence interval 0.40-3.5). CONCLUSIONS: This study provided solid evidence to support that the gastric acid suppression level during PPI treatment does not differ between patients with and without persistent GERD symptoms. The insignificant role of residual gastric acid in the persistent GERD symptoms suggests that the use of medications other than those that enhance gastric acid inhibitory effects would be an essential approach for the management of PPI-refractory GERD.

Ramucirumab for the treatment of gastroesophageal cancers.

INTRODUCTION: In 2014, the U.S. Food and Drug Administration (FDA) approved ramucirumab for use in the second line setting of advanced or metastatic, gastric or gastroesophageal adenocarcinoma (GEAC) based on the result of Phase III clinical trials; REGARD and RAINBOW. AREAS COVERED: We briefly review the mechanisms of angiogenesis, anti-angiogenic therapy, and current status of advanced GEAC treatment then highlight the challenges and future prospects of novel molecular targeted agents. EXPERT OPINION: Although both the REGARD and RAINBOW trials met their primary endpoints of significantly prolonged overall survival (OS) and progression-free survival (PFS), the magnitude of the difference is still relatively modest. Given that ramucirumab alone has a marginal effect, a combination of paclitaxel and ramucirumab is strongly preferred as a second line therapy. To maximize the impact of ramucirumab in patients with GEAC, we can leverage the recent pharmacokinetics (PK) data of ramucirumab from the REGARD and RAINBOW trials. In addition, the quest for identifying biomarkers to select patients who are likely to benefit the most should continue. It is our firm belief that taxanes should no longer be added to the frontline regimens in most cases, given the success of the taxane/ramucirumab in the second line setting.

[Public health nurses' disaster responses for intractable neurological patients at home].

OBJECTIVE: This paper describes the 1995 Hanshin-Awaji Earthquake experience of the local public health nurses. The purpose of the study was to identify problems regarding assistance of intractable neurological patients at home during and after the earthquake and to discuss ways to improve future local disaster responses by public health nurses for those patients. METHODS: Approximately 2 hours of a group interview of public health nurses from 2 public health centers in Kobe City was conducted in August, 1996. Interview data was collected via audio-tape and transcribed. The data was organized according to phases of the earthquake. The acute phase of the earthquake disaster ended within 72 hours. The data was then analyzed to identify problems in assisting intractable neurological home patients in order to discuss disaster responses by public health nurses. RESULTS: There was a delay in confirming the safety of and providing needed assistance for intractable neurological patients at home by public health nurses. During the first 3 days after the earthquake, the majority of public health nurses were unable to commute to work due to the shutdown of transportation systems. In addition, nurses, who were able to come to work, were preoccupied with treating earthquake casualties and distributing medical supplies. Other factors associated with the delay included the following: lack of a registration list for intractable neurological patients at home; lack of close contacts between public health nurses and patients, and between public health nurses and patient support groups; and sparing nurses for guiding volunteers and for coordinating between shelters and hospitals. CONCLUSION: Measures to improve future disaster responses are as follows: a) teaching patients and their families how to safeguard against disaster; b) preparing registration lists; c) establishing support networks and cooperating with network members; and d) upon disaster, assigning some nurses to assess the needs of patients.

The real life of aged persons living alone in a depopulated area--in case of village a in Nagano Prefecture.

Japan adopted a high economic growth policy and developed rapid industrialization since the 1960s. Consequently, Japanese have gotten various positive influences and negative influences. In this paper, we describe various positive influences and also we describe the "real life" of aged persons living alone in depopulated areas as one of the typical negative influences. For the purpose of investigating the actual lives of aged person living alone in depopulated areas, we carried out repeated interviews, research and direct observations of their work and lives in Village A. Village A is located in a mountain area 20 kilometers from Nagano City. The total population of the village was 3,294 in 1993, while it was 6,312 in 1960. The ratio is increasing rapidly year by year. In the village, the number of aged persons over 65 years old living alone, without any family, was 116 in 1994. The highest age is 94 years old. The number is increasing year by year. Through our study, it is made clear that aged persons over 65 years old living alone in the village have to manage everything in their daily lives by themselves to maintain their own safety, while accepting the influences of economic and industrial developments.
