Assessment of Distress among Patients and Primary Caregivers: Findings from a Chemotherapy Outpatient Unit.

BACKGROUND: Chemotherapy is one of the treatment modalities for cancer. The side effects of treatment, at times, can affect the emotional well-being of patients and their caregivers, thereby leading to distress. This paper aims at screening and identifying levels of distress among patients undergoing chemotherapy and their caregivers. SUBJECTS AND METHODS: A cross-sectional study design was used. Patients (n = 102) undergoing chemotherapy in the outpatient daycare unit and their caregivers (n = 101) were screened for distress using the National Comprehensive Cancer Network distress thermometer and the problem checklist. Data were analyzed using descriptive and inferential statistics. RESULTS: Patients (53.4%) and their caregivers (22.2%) reported experiencing moderate-to-severe levels of distress. Patients reported significant distress in the areas of physical (P = 0.000) and emotional problems, whereas caregivers reported distress in the areas of family (P = 0.000) and emotional problems. There was no significant difference in emotional problems (P ≥ 0.05) between the patients and their caregivers. There was a positive correlation between physical and emotional problems (r = 0.760, P = 0.000). Majority of patients (85.2%) and caregivers (80.1%) showed interest to avail psycho-oncology services. CONCLUSIONS: Distress is prevalent among patients with cancer undergoing chemotherapy and their caregivers. Clinical implications highlight the need to identify and address caregiver distress during routine distress screening for patients using specific psychosocial interventions. Future research warrants the use of administering specific assessments to identify severe psychological issues, such as depression and anxiety for patients reporting severe levels of distress on the screening tool.

Does the attire of a primary care physician affect patients’ perceptions and their levels of trust in the doctor?

@#Introduction: With increasing evidence of disease transmission through doctors’ white coats, many countries have discouraged doctors from wearing their white coats during consultations. However, there have been limited studies about patients’ preferences concerning doctors’ attire in Malaysia. This study, therefore, aimed to investigate patients’ perceptions of doctors’ attire before and after the disclosure of information about the infection risk associated with white coats. Method: This cross-sectional study was conducted from 1st June 2015 to 31st July 2015 at three different primary care settings (government, private, and university primary care clinics) using a self-administered questionnaire. A 1:5 systematic random sampling method was employed to select the participants. The respondents were shown photographs of male and female doctors in four different types of attire and asked to rate their level of confidence and trust in and ease with doctors in each type of attire. Subsequently, the respondents were informed of the risk of white coat-carried infections, and their responses were reevaluated. Data analysis was completed using SPSS Version 24.0. Associations of categorical data were assessed using the Chi-Square test, while the overall change in perceptions after the disclosure of additional information was examined using the McNemar test. Results with p-values < 0.05 were considered statistically significant. Results: A total of 299 respondents completed the questionnaire. Most of the respondents had more confidence and trust in the male (62.5%) and female (59.2%) doctors wearing white coats. A high proportion of the respondents from the government clinic (70.5%) felt more confidence in male doctors dressed in white coats (p-value = 0.018). In terms of ethnicity, male doctors in white coats were highly favored by Malays (61.0%), followed by the Chinese (41.2%) and Indians (38%) (p = 0.005). A similar preference was observed for the female doctors, whereby the highest number of Malays (60.3%), followed by the Chinese (41.2%) and Indians (40.0%) (p = 0.006), had a preference for female doctors wearing white coats. Only 21.9% of the initial 71.9% of patients who preferred white coats maintained their preference (p < 0.001) after learning of the risk of microbial contamination associated with white coats. Conclusion: Most patients preferred that primary care doctors wear white coats. Nevertheless, that perception changed after they were informed about the infection risk associated with white coats.

Importance of dose intensity in treatment of advanced non-small cell lung cancer in the elderly.

Maintaining appropriate dose intensity is important not only in the curative setting but also in treatment with palliative intent. We evaluated the outcome of advanced non small cell lung cancer treated with doublet platinum based chemotherapy. Outcome was compared between patients treated by medical oncologists at a tertiary cancer center and those treated by non medical oncologists in the community. The dose intensity, overall response rate and overall survival was significantly better when patients were treated by trained qualified and experienced medical oncologists. Hence, even in the palliative setting, cancer directed systemic therapy will yield maximum benefit for the patients when treated by medical oncologists.

Disposition and tissue distribution of imatinib in a liposome formulation after intravenous bolus dose to mice / 药学学报

Imatinib is an efficacious anticancer drug with a spectrum of potential antitumour applications limited by poor biodistribution at therapeutic concentrations to the tissues of interest. We assess the pharmacokinetic and tissue distribution profile of imatinib in a liposome formulation. Its single dose (6.25 mg x kg(-1)) in a liposome formulation was administered iv to male mice. Imatinib concentration was measured in plasma, spleen, liver, kidney and brain using a HPLC assay. Non-compartmental pharmacokinetic approach was used to assess the disposition parameters. The plasma disposition profile was biphasic with a plateau-like second phase. The AUC(0-->infinity) was 11.24 microg x h x mL(-1), the elimination rate constant (k(el)) was 0.348 h(-1) and the elimination half life (t(1/2)) was 2.0 h. The mean residence time (MRT) was 2.59 h, V(SS) was 1.44 L x kg(-1) and clearance was 0.56 L x h x kg(-1). Liver achieved the highest tissue exposure: CMAX = 18.72 microg x mL(-1); AUC(0-->infinity)= 58.18 microg x h x mL(-1) and longest t(1/2) (4.29 h) and MRT (5.31 h). Kidney and spleen AUC(0-->infinity) were 47.98 microg x h x mL(-1) and 23.46 microg x h x mL(-1), respectively. Half-life was 1.83 h for the kidney and 3.37 h for the spleen. Imatinib penetrated into the brain reaching approximately 1 microg x g(-1). Upon correction by organ blood flow the spleen showed the largest uptake efficiency. Liposomal imatinib presented extensive biodistribution. The drug uptake kinetics showed mechanism differences amongst the tissues. These findings encourage the development of novel imatinib formulations to treat other cancers.
