Pancreatic cancer: analysis of disease and treatment options
Pancreatic cancer is a lethal disease with very poor prognosis as it is one of the leading causes of cancer related deaths worldwide. Pancreatic cancer may manifest in different ways and there are a number of different genetic mutations that can lead to carcinomas of the pancreas. This study reviewed some of the genetic alterations seen in pancreatic cancer and how they appear in the context of disease progression. While progress has been made in identifying genetic mutations that may contribute to pancreatic cancer, more work has to be done to solidify biomarkers and potentially contribute to early detection of the disease.
Pancreatic cancer is often asymptomatic until late stages of disease, which is why it is often diagnosed at such a progressed state. Late detection contributes to its poor prognosis as it unlikely to have curative potential at such a late stage. Approach to treatment generally depends on the stage at diagnosis. This study reviewed a number of different treatment options including surgical resection, chemotherapy, and targeted therapy. Surgical resection is currently considered the only cure for pancreatic cancer. The other treatment options may be helpful in reducing recurrence of cancer and/or increasing survival. Targeted therapy is a very recent approach that is currently used as a treatment to manage pancreatic cancer with fairly positive outcomes. Hopefully, with further exploration into this individualized approach and modification of current targeted agents we are able to discover a cure for this devastating disease
The Experience of Essential Tremor Caregivers: Burden and Its Correlates
BackgroundEssential tremor (ET) is associated with physical and cognitive impairments, as well as embarrassment, avoidance of social settings, and related difficulties that negatively impact the lives of patients. In similar disease contexts, burden on friends and relatives acting as caregivers has been noted and has well-documented implications. There has been no study examining caregiver burden related to ET.MethodsData were gathered from 55 ET participants enrolled in a clinical study and their caregivers. The Zarit Burden Interview was used to assess caregiver burden. To assess clinical features that may be associated with burden, we collected several variables including the Montreal Cognitive Assessment, self-reported tremor disability, a videotaped neurological examination, questionnaires assessing ET participants’ suffering, caregivers’ perceptions of that suffering, and both caregiver and ET participant depressive symptoms. Spearman’s correlations were performed between caregiver burden and clinical features, and we created a multivariate linear regression model predicting caregiver burden.ResultsMany ET caregivers provide little to no care and experience little to no burden. However, some caregivers (11%) provide over 25 h of care/week, and 13% experience high levels of burden. Caregivers most commonly provided assistance with writing and cooking. Increased burden was associated with the ET participants’ decreased cognition, more caregiving tasks, more hours/week of caregiving activities, a longer duration of care, more ET participant falls/year, more medications taken by the ET participant, and more depressive symptoms in both the ET participant and the caregiver (all p < 0.05). ET participants’ suffering and their caregivers’ perceptions of suffering were both associated with increased burden. Neither tremor severity score nor self-reported tremor disability score was associated with increased caregiver burden. Using a multivariate linear regression model, we found that caregivers’ increased perception of their partners’ suffering was the best predictor of caregiver burden.ConclusionWhile not all relatives and friends of ET patients provide extensive care or experience high burden, there is a group reporting high levels of caregiver burden that requires the attention and counseling of clinicians. This burden is associated with primarily non-tremor symptoms of ET and with caregivers’ perception that their partners are suffering

Psychological Suffering in Essential Tremor: A Study of Patients and Those Who Are Close to Them
Background: Although the motor and non-motor features of essential tremor (ET) have been characterized in detail, it is not known whether ET patients suffer psychologically and whether those who are close to them consider them to be suffering in this way.
Methods: Fifty ET patients and 50 “close others” (COs), identified by patients “as someone who knows you well and sees you often” and who can “provide a different perspective on your well-being”, reported their own depressive symptoms, daily stress, and perceptions of patient psychological suffering and patient overall suffering with validated scales. ET patients’ tremor severity, duration, disability, cognition, and number of medications were also assessed.
Results: ET patients reported levels of psychological suffering within the range documented in arthritis and dementia patients from previous studies, and COs perceived significantly more psychological suffering in patients than patients reported themselves. Regression models, controlling for tremor severity, duration, and disability revealed that patients’ greater psychological suffering was associated with greater patient depression. The greater perceptions of COs of patient psychological and overall suffering were associated with greater CO depression and daily stress. Sensitivity analysis showed that patients’ cognitive status or number of medications did not affect the results.
Discussion: Multidisciplinary teams caring for ET patients should look beyond simple clinical ET indicators. They should be aware of patient experiences and perceptions of COs of psychological and overall suffering. This will help guide the development of evidence-based, supportive interventions that improve communication about the needs of ET patients and those who are close to them
Preliminary validation of a questionnaire assessing psychological distress in caregivers of patients with malignant mesothelioma: Mesothelioma Psychological Distress Tool-Caregivers
Objective To develop a short, flexible, and comprehensive tool to measure psychological distress in caregivers of malignant mesothelioma (MM) patients: the Mesothelioma Psychological Distress Tool-Caregivers version (MPDT-C). Methods Based on a systematic review of the relevant literature, aspects associated with caregiver distress were derived. Expert researchers/clinicians developed a pool of items for each identified aspect. Content validity was assessed through a multiple mixed-methods approach. A multicenter study was conducted to explore the factorial structure of the 47-item MPDT-C through Bayesian factor analysis. Results The Bayesian exploratory factor analysis revealed an underlying three-factor structure. Factors were labeled Secondary Traumatic Stress, Engagement in Caring, and Meaningful Cognitive Restructuring. All scales showed sufficient reliability and corrected item-total correlations. Females scored higher than males for Engagement in Caring. Conclusions Taking care of malignant mesothelioma patients is a stressful process that influences the caregiver's physical, emotional, and social wellbeing. Our study offers preliminary evidence in support of the adequate psychometric properties of the MPDT-C, and these should now be replicated. Results suggest that the MPDT-C is a reliable tool with which to detect the psychological distress of this traumatized population
