Patients' spontaneous discourse on the importance of significant others in the course of transplantation: A qualitative study

Background: This study explores significant ones' implication before and after transplantation. Methods: Longitudinal semi-structured interviews were conducted in 64 patients awaiting all-organ transplantation. Among them, 58 patients spontaneously discussed the importance of their significant other in their daily support. Discourse analysis was applied. Findings: During the pre-transplantation period renal patients reported that significant others took part in dialysis treatment and participated to regimen adherence. After transplantation, quality of life improved and the couple dynamics returned to normal. Patients awaiting lung or heart transplantation were more heavily impaired. Significant others had to take over abandoned roles. After transplantation resuming normal life became gradually possible, but after one year either transplantation health benefits relieved physical, emotional and social loads, or complications maintained the level of stress on significant others. Discussion: Patients reported that significant others had to take over various responsibilities and were concerned about long-term stress that should be adequately supported.

Medical students' skills and needs for training in breaking bad news.

This study assessed medical students' perception of individual vs. group training in breaking bad news (BBN) and explored training needs in BBN. Master-level students (N = 124) were randomised to group training (GT)-where only one or two students per group conducted a simulated patient (SP) interview, which was discussed collectively with the faculty-or individual training (IT)-where each student conducted an SP interview, which was discussed during individual supervision. Training evaluation was based on questionnaires, and the videotaped interviews were rated using the Roter Interaction Analysis System. Students were globally satisfied with the training. Still, there were noticeable differences between students performing an interview (GT/IT) and students observing interviews (GT). The analysis of the interviews showed significant differences according to scenarios and to gender. Active involvement through SP interviews seems required for students to feel able to reach training objectives. The evaluation of communication skills, revealing a baseline heterogeneity, supports individualised training.

L'hémopéritoine spontané: diagnostic, pronostic et thérapeutiques possibles [Spontaneous hemoperitoneum: diagnosis, prognosis and possible therapeutics]

We report the case of a 58-year-old diabetic man admitted to the hospital in a comatose state due to medicamentous hypoglycemia in a context of hypovolemic acute renal failure. Hypovolemia was due to hemoperitoneum in a alcoholic patient with cirrhotic hepatic failure. CT-scan and arterial angiographies revealed a voluminous isolated hepatic mass with active bleeding suggesting the diagnosis of spontaneous bleeding from a hepatocellular carcinoma. The hemorrhage resolved after selective arterial embolization, but the patient died two weeks later from an infectious cause. The differential diagnosis of a spontaneous hemoperitoneum and possibilities of treatment in the case of ruptured hepatocellular carcinoma are discussed.

Spontaneous NA+ transients in individual mitochondria of intact astrocytes.

Mitochondria in intact cells maintain low Na(+) levels despite the large electrochemical gradient favoring cation influx into the matrix. In addition, they display individual spontaneous transient depolarizations. The authors report here that individual mitochondria in living astrocytes exhibit spontaneous increases in their Na(+) concentration (Na(mit)(+) spiking), as measured using the mitochondrial probe CoroNa Red. In a field of view with approximately 30 astrocytes, up to 1,400 transients per minute were typically detected under resting conditions. Na(mit)(+) spiking was also observed in neurons, but was scarce in two nonneural cell types tested. Astrocytic Na(mit)(+) spikes averaged 12.2 +/- 0.8 s in duration and 35.5 +/- 3.2 mM in amplitude and coincided with brief mitochondrial depolarizations; they were impaired by mitochondrial depolarization and ruthenium red pointing to the involvement of a cation uniporter. Na(mit)(+) spiking activity was significantly inhibited by mitochondrial Na(+)/H(+) exchanger inhibition and sensitive to cellular pH and Na(+) concentration. Ca(2+) played a permissive role on Na(mit)(+) spiking activity. Finally, the authors present evidence suggesting that Na(mit)(+) spiking frequency was correlated with cellular ATP levels. This study shows that, under physiological conditions, individual mitochondria in living astrocytes exhibit fast Na(+) exchange across their inner membrane, which reveals a new form of highly dynamic and localized functional regulation.

Historia morbi atrocis--deux nouveaux cas de ruptures spontanées de l'oesophage (syndrome de Boerhaave) [Historia morbi atrocis--2 new cases of spontaneous rupture of the esophagus (Boerhaave syndrome)].]

We report the case of two patients hospitalized within a few weeks of each other and both presenting with spontaneous rupture of the esophagus whose evolution proved fatal. We take the opportunity of drawing attention to this rare and challenging disease, which is often diagnosed too late.
