Distorted Memories and Related Factors in ICU Patients.

This study aimed to examine the relationship between memory status of and factors related to patients in the intensive care unit (ICU) using a cross-sectional study design. Participants were adult patients who were admitted to the general ICUs for more than 48 hours. One week after ICU discharge, a survey on memory distortion was conducted. Overall, 133 patients were included, of whom 51.1% reported distorted memories. Among them, 15.0% had memory loss; 48.1% had unrealistic experiences; 27.8% recalled confusion, panic, anxiety, and discomfort during their ICU stay; and 9% had traumatic experiences. Multiple logistic regression analyses revealed that memory loss was associated with an operation, and a significant association was observed between traumatic memory and pain. Opioid use may have a protective effect against memory loss. These results suggest the importance of relieving pain and preserving true memories during ICU treatment.

Identifying cues of distorted memories in intensive care by focus group interview of nurses.

AIM: To determine cues to identify intensive care unit patients with distorted memories and related practices. DESIGN: Qualitative descriptive study. METHODS: Twenty nurses were included in semi-structured focus groups. Qualitative content analysis was conducted. RESULTS: Cues and nursing practices related to distorted memories emerged under the following categories: "Get to know daily life before admission," "Facial expressions and behaviour are different from usual," "Pay close attention to the treatment outcome," "Notice it after the fact," "Sharing patients' intensive care unit experiences" and "Creates a new life." Nurses tried to detect distorted memories by observing the patients' facial expressions, medication effects and delirium presence during their normal lives and treatments, while trying to understand the patients' intensive care unit experiences and provide care that promotes autonomous living. This study emphasizes the importance of support for reconstructing ordinary life through communication and rehabilitation, in addition to support for medical care for distorted memories.

Development of a self-adjusting magnetic attachment for implant overdentures.

This study aimed to clarify the efficacy of a newly developed self-adjusting magnetic attachment (SMAT) that allowed 0.4 mm of vertical and 8 degrees of rotational movements using an in vitro model. Comparison between the SMAT and a conventional magnetic attachment (CMAT) was performed for the retentive force under different dislodgement directions. Lateral forces to the abutment were also compared among the SMAT, CMAT, dome-shaped magnetic attachment, and a ball attachment. The SMAT maintained retentive force more effectively than the CMAT, even in oblique directions of dislodgement. A smaller lateral force to the abutment was found for the SMAT compared to the CMAT or ball attachment.

Influence of bonded composite resin cingulum rest seats on abutment tooth periodontal tissues: a longitudinal prospective study.

This study aimed to examine the longitudinal influence of bonded composite resin cingulum rest seats on abutment tooth periodontal tissues in removable partial dentures (RPDs). Twenty-eight patients with RPDs were enrolled in the study. Thirty-one cingulum rest seats were prepared for an anterior tooth using composite resin and a standardized method for each patient. Periodontal indices such as probing pocket depth (PD), bleeding on probing (BoP), and tooth mobility (TM) were measured at the time of denture insertion (baseline) and at least 3 months postinsertion (up to 8 years). Control data were obtained from the remaining nonprepared anterior teeth on the other side of the arch. None of the bonded resin rest seats failed, but slight abrasion was observed in 3 rest seats. No significant differences were found in terms of PD, BoP, and TM between baseline and postinsertion data for abutments with bonded resin rest seats and controls. It is suggested that bonded composite resin cingulum rest seats can be used longitudinally without damaging the periodontal tissues of abutment teeth.
