AI Article Synopsis

  • The study aimed to evaluate the effectiveness of two Malay language questions (TQWHQ) for detecting depression, supplemented with an additional help question to improve accuracy.
  • Conducted in a Malaysian primary care clinic with 146 women patients, the results showed very high sensitivity (99%) and good specificity (70%) for the original two questions, while the help question significantly raised specificity to 95%.
  • The findings suggest that these brief questions are reliable for identifying depression cases in primary care settings, and translation did not compromise their validity.

Article Abstract

Objective: To determine the diagnostic accuracy of the two questions with help question (TQWHQ) in the Malay language. The two questions are case-finding questions on depression, and a question on whether help is needed was added to increase the specificity of the two questions.

Method: This cross sectional validation study was conducted in a government funded primary care clinic in Malaysia. The participants included 146 consecutive women patients receiving no psychotropic drugs and who were Malay speakers. The main outcome measures were sensitivity, specificity, and likelihood ratios of the two questions and help question.

Results: The two questions showed a sensitivity of 99% (95% confidence interval 88% to 99.9%) and a specificity of 70% (62% to 78%), respectively. The likelihood ratio for a positive test was 3.3 (2.5 to 4.5) and the likelihood ratio for a negative test was 0.01 (0.00 to 0.57). The addition of the help question to the two questions increased the specificity to 95% (89% to 98%).

Conclusion: The two qeustions on depression detected most cases of depression in this study. The questions have the advantage of brevity. The addition of the help question increased the specificity of the two questions. Based on these findings, the TQWHQ can be strongly recommended for detection of depression in government primary care clnics in Malaysia. Translation did not apear to affect the validity of the TQWHQ.

Objectives: To analyze the CT imaging features of extranodal natural killer/T (NK/T)-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI), and to compare them with those of Crohn's disease (CD) and diffuse large B-cell lymphoma (DLBCL).

Materials And Methods: Data were retrospectively collected from 17 patients diagnosed with GI ENKTCL-NT, 68 patients with CD, and 47 patients with DLBCL. The CT findings of ENKTCL-NT were analyzed and compared with those of CD and DLBCL.

Objectives: This research describes four aspects of the development of the Sense of Safety Theoretical Framework for whole person care: exploring the meaning of the phrase "sense of safety"-the whole person ; the range of human experience that impacts sense of safety-whole person ; the dynamics that build sense of safety-the healing ; and the personal and cross-disciplinary trauma-informed practitioner that facilitate sense of safety.

Methods: This qualitative participatory study was conducted in two phases. Researchers iteratively explored the concept of sense of safety using focus groups and semi-structured interviews.

Reminiscence is a meaningful activity for people with dementia, but research implementing digital reminiscence tools into environments with older people is not well developed. This project sought to understand the effectiveness of a digital reminiscence tool in aiding person-centred dementia care with people attending a day respite centre and a group residential home, in metropolitan eastern Australia. This study used semi-structured interviews and ethnographic observations using a qualitative reflexive thematic analysis with seventeen participants including people with dementia ( = 8), their loved ones ( = 5) and staff = 4) Themes identified were: 1.
