METHODS: Nineteen units participated with intention of including 100 patients per site as close to a consecutive series as possible in order to minimize selection bias.
RESULTS: There were 2136 patients with a median total number of PCI items selected of 5 (2-10). "Fear of the cancer returning" (39%) and "dry mouth" (37%) were most common. Twenty-five percent (524) reported less than good QOL.
CONCLUSION: There was considerable variation between units in the number of items selected and in overall QOL, even after allowing for case-mix variables. There was a strong progressive association between the number of PCI items and QOL.
MATERIALS AND METHODS: Two hundred and ten students completed a validated questionnaire on SOC and SDLR. The percentage of marks obtained by these students in their year-end examination was used as their academic performance. The SOC scores were further divided into three hierarchical clusters using cluster analysis. The data were analyzed to determine the difference in the SDLR scores and academic performance among the three clusters. Furthermore, the relationship between SOC scores, SDLR scores, and academic performance was assessed.
RESULTS: The SDLR scores significantly increased from the low SOC cluster to the high SOC cluster (P = 0.026). However, there was no significant change in academic performance. A positive relationship was found between the SOC and the academic performance (R = +0.025; P > 0.05). The SDLR had a significant positive relationship with both SOC and academic performance (R = +0.27; P < 0.001).
CONCLUSION: Although SOC may not have a direct influence on academic performance, SDLR can play an intermediary role. Early identification and timely intervention in students with a weak SOC and low SDLR can have a beneficial influence on their academic life.
METHODS: A structured self-administered questionnaire was developed at Najran University and provided to the participants for data collection. The data collected included information on risk perception and incorporation of measures for protection against COVID-19 to gauge the attitude of dentists during this period. Also, clinical implementation of various protective measures was reviewed.
RESULTS: Of the n = 322 dentists that answered the questions, 50% were general dentists and 28.9% were dentists working at specialist clinics, while the remaining 21.1% of dentists were employed in academic institutions. Among the newer additions to the clinic, 36.3% of dentists answered that they had added atomizers to their practices, followed by 26.4% of dentists that had incorporated the use of UV lamps for sterilization. We found that 18.9% dentists were using HEPA filters in their clinics, while 9.9% of dentists were making use of fumigation devices to control the risk of infection. One-way ANOVA was also carried out to demonstrate that there was a statistically significant difference (p = 0.049) between groups of dentists utilizing HEPA filters, UV lamps, atomizers, and fumigation devices to prevent the spread of SARS-CoV2 across their workplaces.
CONCLUSION: Dentists are aware of recently updated knowledge about the modes of transmission of COVID-19 and the recommended infection control measures in dental settings. A better understanding of the situation and methods to prevent it will ensure that the dental community is able to provide healthcare services to patients during the pandemic.
OBJECTIVE: To assess knowledge and perceptions regarding PD in a large multiethnic urban Asian cohort of patients and caregivers.
METHODS: We conducted a survey at a university hospital neurology clinic, using a novel Knowledge and Perception of Parkinson's Disease Questionnaire (KPPDQ).
RESULTS: The KPPDQ had satisfactory psychometric properties among patients and caregivers. Five hundred subjects were recruited with a 97% response rate (211 patients, 273 caregivers). Non-motor symptoms such as urinary problems, visual hallucinations and pain were relatively poorly recognized. Many (≈ 50-80%) respondents incorrectly believed that all PD patients experience tremor, that PD is usually familial, and that there is a cure for PD. About one-half perceived PD to be caused by something the patient had done in the past, and that PD medications were likely to cause internal organ damage. Issues of stigma/shame were relevant to one-third of patients, and 70% of patients perceived themselves to be a burden to others. Two-thirds of participants felt that PD imposed a heavy financial toll. Participants were about equally divided as to whether they would consider treatment with deep brain stimulation, tube feeding or invasive ventilation. Over three-quarters of patients expressed a preference to die at home.
CONCLUSIONS: Important knowledge gaps, misperceptions and perspectives on PD were identified, highlighting the need for further efforts to raise awareness and provide accurate information regarding PD, and to address patient's and caregivers' needs and preferences.
DESIGN: This was a cross-sectional study. Three hundred forty-two members of the public with tinnitus volunteered to complete a survey comprising a series of questionnaires and subscales of questionnaires measuring each of the constructs contained within the Cognitive Behavioral Model of Tinnitus Distress. The optimum factor structure of each measure for the study population was established, and the resulting factors were used to construct a series of path models based on the theoretical model. Path analysis was conducted for each of these, and the goodness of fit of the models was assessed using established fit criteria.
RESULTS: Five of the six path models tested reached the threshold for adequate fit, and further modifications improved the fit of the three most parsimonious of these. The two best-fitting models had comparable fit indices which approached the criteria for good fit (Root Mean Square Error of Approximation = 0.061, Comparative Fit Index = 0.984, Tucker Lewis Index = 0.970 and Root Mean Square Error of Approximation = 0.055, Comparative Fit Index = 0.993, Tucker Lewis Index = 0.982). They differed principally in the placement of tinnitus magnitude and the inclusion/noninclusion of control beliefs.
CONCLUSIONS: There are theoretical arguments to support both a beliefs-driven and a loudness-driven model, and it may be that different configurations of the Cognitive Behavioral Model of Tinnitus Distress are more appropriate to different groups of people with tinnitus. Further investigation of this is needed. This notwithstanding, the present study provides empirical support for a model of tinnitus distress which provides a clinical framework for the development of more effective psychological therapy.
DESIGN: Instrument development.
METHOD: Focus group discussions were conducted among informal carers and healthcare specialists in March 2017. The content validity was determined by the mean of the item content validity index. A reliability test was performed by the Kuder-Richardson 20 and Pearson's correlation coefficient among 40 informal carers of patients with a traumatic brain injury in the rehabilitation medicine department of a tertiary hospital from August-September 2017.
RESULTS: The final 34-item questionnaire covers the nature of traumatic brain injury, the consequences of traumatic brain injury, the rehabilitation process, and the role of the caregiver. The item content means ranged from 0.8-1.00, and the difficulty of knowledge items ranged from 0.18-0.98. The internal consistency reliability and correlation coefficient were 0.70 and 0.84, respectively.
