The symptoms of thiamine deficiency vary considerably and asymptomatic cases; i.e., subclinical thiamine deficiency (SCTD), are known to exist. However, there is no information available on the treatment of SCTD.

We report a patient who underwent intravenous thiamine replacement therapy for about a month after being diagnosed with SCTD, but who developed SCTD again about three weeks after finishing the treatment.

The patient was a 64-year-old woman who, after starting treatment for cervical cancer, complained of anxiety and underwent an initial psychiatric examination. The psychiatric diagnosis was an adjustment disorder. Based on the possibility of SCTD complications due to her decreased appetite and weight loss, her serum thiamine concentration was measured and found to be low. Therefore, thiamine was administered intravenously for 29 days. At the end of treatment, thiamine administration was discontinued as there were no apparent neuropsychiatric symptoms or problems with appetite. Twenty-three days later, there were still no problems with appetite or neuropsychiatric symptoms, but a follow-up blood sample revealed that her serum thiamine was again below the normal range.

Currently, there is no information available regarding the diagnosis and treatment of SCTD in cancer patients. In some cases, such as this case, the deficiency recurs without any symptoms indicative of SCTD; therefore, further examination for diagnosis and treatment is necessary.

Delirium is a common complication in palliative care patients, especially in the terminal phase of the illness. To date, evidence regarding risk factors and prognostic outcomes of delirium in this vulnerable population remains sparse.

In this prospective observational cohort study at a tertiary care center, 410 palliative care patients were included. Simple and multiple logistic regression models were used to identify associations between predisposing and precipitating factors and delirium in palliative care patients.

The prevalence of delirium in this palliative care cohort was 55.9% and reached 93% in the terminally ill. Delirium was associated with prolonged hospitalization (p < 0.001), increased care requirements (p < 0.001) and health care costs (p < 0.001), requirement for institutionalization (OR 0.11; CI 0.069–0.171; p < 0.001), and increased mortality (OR 18.29; CI 8.918–37.530; p < 0.001). Predisposing factors for delirium were male gender (OR 2.19; CI 1.251–3.841; p < 0.01), frailty (OR 15.28; CI 5.885–39.665; p < 0.001), hearing (OR 3.52; CI 1.721–7.210; p < 0.001), visual impairment (OR 3.15; CI 1.765–5.607; p < 0.001), and neoplastic brain disease (OR 3.63; CI 1.033–12.771; p < 0.05). Precipitating factors for delirium were acute renal failure (OR 6.79; CI 1.062–43.405; p < 0.05) and pressure sores (OR 3.66; CI 1.102–12.149; p < 0.05).

Our study identified several predisposing and precipitating risk factors for delirium in palliative care patients, some of which can be targeted early and modified to reduce symptom burden.

With people living longer, palliative care may be required for lengthier periods of time. This puts demands on healthcare organizations to provide optimal palliative care. Maintaining dignity is central for any person's health and quality of life, but especially for a person with palliative care needs. Dignity-conserving care needs to be evaluated to increase knowledge about outcomes and how to assess these. The purpose of this integrative review was to identify outcomes studied within dignity-conserving care and how these have been operationalized.

An integrative review was conducted in 26 quantitative or mixed-method studies and study protocols. Thematic synthesis with an abductive approach was used for analysis.

Seven themes of studied outcomes were identified, as well as four cluster themes: themes related to Illness-Related Concerns, themes related to the Dignity-Conserving Repertoire, themes related to the Social Dignity Inventory, and themes regarding Overarching Dignity Issues. Most outcomes studied dealt with Illness-Related Concerns within the themes of “Performance, symptoms and emotional concerns” and “End-of-life and existential aspects”. Themes linked to the Social Dignity Inventory had the lowest number of outcomes studied. Outcomes regarding overarching dignity issues such as “Dignity-related distress” and “Quality of life” were common. However, the results lacked concrete communication outcomes.

The results will underpin future research in which dignity-conserving care is implemented and evaluated, and contribute to the provision of evidence-based palliative care. A greater focus on outcomes within cluster themes related to the Dignity-Conserving Repertoire and the Social Dignity Inventory is needed, as is more focus on communication outcomes.

South Asian migrants have a higher burden of life-threatening diseases and chronic diseases compared to other ethnic groups. Yet, knowledge gaps remain around their palliative care needs in the host countries. The aim of the review was to present results from a systematic literature review of available international evidence on experiences with and perspectives on palliative care among older South Asian migrants, relatives, and healthcare providers.

A systematic review in accordance with PRISMA guidelines was conducted in February 2018, searching PubMed, CINAHL, PsychINFO, and EMBASE databases. PROSPERO #CRD42018093464. Studies included empirical research, providing international evidence on experiences and perspectives on palliative care of South Asian migrants and were published between 2000 and 2018. Thematic synthesis was used to analyze data.

A total of 30 articles were included: qualitative (24), quantitative (5), and mixed methods (1). Three main themes were discovered: 1) palliative care practice within the family, 2) trust as a precondition of palliative care, and 3) the importance of knowledge and cultural competency. All the themes, to a greater or lesser extent, are related to access to and use of palliative care services by South Asian migrant families.

Involvement of family members in palliative care decision making could improve the satisfaction of South Asian migrant families toward the service. For example, Advanced Care Planning involving family members could be a possible way to engage family members in palliative care decision making. Supportive interventions, e.g. providing knowledge, aimed at patients and their family members might improve knowledge and increase awareness among South Asian migrant families of palliative care. Knowledge gained from this review could be implemented with other ethnic minority groups.

Major depressive disorder (MDD) is common in patients diagnosed with advanced cancer (AC), with a prevalence of 16.5%. It is associated with great disability and worsened quality of life, increased number and intensity of physical symptoms, and lower survival. It is the main factor for the presence of suicidal ideation. Antidepressants show modest efficacy, and response requires several weeks. Ketamine has demonstrated a fast and robust antidepressant effect in subanesthetic doses. This effect may prove useful in patients with AC, MDD, and suicidal risk.

We report a case of a patient with advanced cervical cancer who presented with uncontrollable pain, MDD, and a suicide attempt.

A 39-year-old woman diagnosed with cervical cancer stage IVB presented to the Emergency Department after a suicide attempt by hanging. Upon evaluation by the palliative care psychiatrist, she reported intense pain, unresponsive to analgesics, and had a history of persistent suicidal ideation. Antidepressant treatment was started (sertraline 50mg/d) after a single dose of ketamine hydrochloride IV (0.5 mg/kg) was administered. Treatment response was measured using the Brief Edinburgh Depression Scale before and after the intervention. The depressive symptoms decreased by 17% on day 1, 39% on day 3, and 72% on day 17.

This case report shows ketamine's efficacy as an augmentation agent alongside conventional antidepressant treatment in patients with AC. Moreover, it shows rapid response in suicidal ideation that has not been achieved with treatment as usual. More clinical trials are needed to support the potential benefit and safety of ketamine in patients with AC, MDD, and persisting suicidal ideation.

Pain treatment is an essential component of care for elderly patients with advanced dementia. The objective of this study was to identify and analyze the different scales used for pain assessment in elderly persons diagnosed with dementia, in the literature available at the Latin American level.

A systematic review was performed on the existing scales for pain assessment in elderly people diagnosed with Alzheimer's disease, vascular dementia, and dementia with Lewy bodies.

226 articles were retrieved from the PUBMED, BIREME, and Scielo databases, of which a total of 10 articles entered the systematic review. The instruments identified in these publications were PAINAD, Abbey, McGill, and PACSLAC, while the Colored Pain Scale, Faces Pain Scale, and VAS scales were used as the silver standard. In Spanish, the Abbey scale, and in Portuguese, the PACSLAC scale showed the best reliability and validity coefficients.

It is concluded that there are only two appropriate scales for the assessment of pain in people with dementia in the region of interest of this study. It is recommended to generate more evidence for a more accurate assessment of pain in people with dementia.

From case reports, haloperidol administration has been associated with QTc prolongation, torsades de pointes, and sudden cardiac death. In a vulnerable population of critically ill patients after cardiac surgery, however, it is unclear whether haloperidol administration affects the QTc interval. Thus, the aim of this study is to explore the effect of haloperidol in low doses on this interval.

This retrospective cohort study was performed on a cardio-surgical intensive care unit (ICU), screened 2,216 patients and eventually included 68 patients with delirium managed with oral and intravenous haloperidol. In this retrospective analysis, electrocardiograms were taken prior and within 24 h after haloperidol administration. The effect of haloperidol on QTc was determined with a Person correlation, and inter-group differences were measured with new long QT comparisons.

In total, 68 patients were included, the median age was 71 (64–79) years and predominantly male (77%). Haloperidol administration followed ICU admission by three days and the cumulative dose was 4 (2–9) mg. As a result, haloperidol administration did not affect the QTc (r = 0.144, p = 0.23). In total, 31% (21/68 patients) had a long QT before and 27.9% (19/68 patients) after haloperidol administration. Only 12% (8/68 patients) developed a newly onset long QT. These patients were not different in the route of administration, cumulative haloperidol doses, comorbidities, laboratory findings, or medications.

These results indicated that low-dose intravenous haloperidol was safe and not clinically relevant for the development of a newly onset long QT syndrome or adverse outcomes and support recent findings inside and outside the ICU setting.

Providing care to a loved one with cancer places demands on caregivers that result in changes to their daily routines and disruptions to their social relationships that then contribute to loneliness. Though caregivers’ psychosocial challenges have been well studied, loneliness — a determinant of health — has not been well studied in this population. This narrative review sought to describe the current evidence on loneliness among caregivers of cancer patients. We aimed to (1) define loneliness, (2) describe its prevalence, (3) describe the association between loneliness and health outcomes, (4) describe risks and consequences of loneliness among cancer caregivers, (5) identify ways to assess loneliness, and (6) recommend strategies to mitigate loneliness in this unique population.

We used evidence from articles listed in PubMed, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases, book chapters, and reports. Articles were reviewed for the following inclusion criteria: (1) published in English, (2) caregivers of cancer patients, (3) loneliness as a study variable, and (4) peer-reviewed with no restriction on the timeframe of publication. Caregivers were defined as relatives, friends, or partners who provide most of the care and support for someone with cancer.

Eighteen studies met inclusion criteria and were included in the analysis. Caregivers’ experiences of loneliness can contribute to negative effects on one's social, emotional, and physical well-being. Social support interventions may not be sufficient to address this problem. Existing recommendations to mitigate loneliness include cognitive and psychological reframing, one-on-one and group therapy, befriending, resilience training, and technology-based interventions.

Limited attention to loneliness in cancer caregivers poses a twofold problem that impacts patient and caregiver outcomes. Interventions are critically needed to address loneliness as a determinant of health in caregivers, given their pivotal role in providing care and impacting health outcomes for people with cancer.

Palliative care plays an essential role in enhancing the quality of life and quality of death for residents in long-term care homes (LTCHs). Access to palliative care specialists is one barrier to providing palliative care to LTCHs. This project focused on palliative telemedicine, specifically evaluating whether integration of early palliative care specialist consultation into an LTCH would be feasible through the implementation of videoconferencing during routine interdisciplinary care conferences.

This was a mixed-methods evaluation of a pilot program implementation over 6 months, to integrate early palliative care into an LTCH. There were two pilot communities with a total of 61 residents. Resident demographics were collected by a chart review, and palliative telemedicine feasibility was evaluated using staff and family member surveys.

For the 61 residents, the average age of the residents was 87 years, with 61% being female and 69% having dementia as the primary diagnosis. The mean CHESS (Change in Health, End-Stage Disease, Signs, and Symptoms) and ADL (Activities of Daily Living) scores were 0.8 and 4.0, respectively, with 54% having a Palliative Performance Scale score of 40. Seventeen clinical staff surveys on palliative teleconferences were completed with the majority rating their experience as high. Ten out of the 20 family members completed the palliative teleconference surveys, and the majority were generally satisfied with the experience and were willing to use it again. Clinical staff confidence in delivering palliative care through telemedicine significantly increased (P = 0.0021).

The results support the feasibility of videoconferencing as a means of palliative care provision. Despite technical issues, most clinical staff and families were satisfied with the videoconference and were willing to use it again. Early integration of palliative care specialist services into an LTCH through videoconferencing also led to improved self-rated confidence in the palliative approach to care by clinical staff.

The case of a non-oncological patient at the end of his life, admitted to a Palliative Care Unit (PCU), is presented. After a failed attempt to place a central venous catheter (CVC) and another placement of a peripherally inserted central catheter (PICC), the patient exhibited high anxiety regarding a midline catheter (MC) and refused its placement, even though this was necessary for the administration of intravenous drugs to control dyspnea and other complex symptoms that he presented.

An intervention through clinical hypnosis for successful MC placement and symptom control is described.

Through clinical hypnosis and interdisciplinary teamwork, it was possible to place a MC, necessary for symptomatic control of a complex patient.

This case exemplifies hypnosis as a simple procedure that is easy to apply, accepted by the patient, and effective in the implementation of invasive procedures and symptom control in PCUs.

Recognizing and managing existential suffering remains challenging. We present two cases demonstrating how existential suffering manifests in patients and how to manage it to alleviate suffering.

Case 1: A 69-year-old man with renal cell carcinoma receiving end-of-life care expressed fear of lying down “as he may not wake up.” He also expressed concerns of not being a good Christian. Supportive psychotherapy and chaplain support were provided, with anxiolytic medications as needed. He was able to express his fear of dying and concern about his family, and Edmonton Symptom Assessment System scores improved. He died peacefully with family at bedside. Case 2: A 71-year-old woman presented with follicular lymphoma and colonic obstruction requiring nasogastric drain of fecaloid matter. Initially, she felt that focusing on comfort rather than cure symbolized giving up but eventually felt at peace. Physical symptoms were well-controlled but emotionally she became more distressed, repeatedly asking angrily, “Why is it taking so long to die?.” She was supported by her family through Bible readings and prayers, but she was distressed about being a burden to them. An interdisciplinary approach involving expressive supportive counseling, spiritual care, and integrative medicine resulted in limited distress relief. Owing to increasing agitation, the patient and family agreed to titrate chlorpromazine to sedation. Her family was appreciative that she was restful until her death.

Existential suffering manifests through multiple domains in each patient. A combination of pharmacologic and non-pharmacologic techniques may be needed to relieve end-of-life suffering.

To evaluate sleep disturbances and to verify the accuracy of three screening tests to detect them in patients at the end-of-life admitted in a hospital palliative care unit.

The level of sleep disturbances was evaluated through the Pittsburgh Sleep Quality Index (PSQI) in 150 palliative patients. This questionnaire was the criterion variable for testing the three screening tests used: Edmonton Symptom Assessment System (ESAS-Sleep subscale); the single question “How much do you worry about your sleep problems?” which is answered on a scale of 0–10 (Sleep-Worry-Q) and another single question: “Do you think you have sleep problems?” with two response categories, Yes/No (Sleep-Problem-Q).

According to the PSQI (cut-off point: 8), 87% of patients presented sleep disturbances. The ESAS-Sleep (cut-off point: 3) showed a sensitivity of 0.87, a specificity of 0.58, and an AUC of 0.729; the Sleep-Worry-Q (cut-off point: 4) showed a sensitivity of 0.95, a specificity of 0.68, and an AUC of 0.854; the Sleep-Problem-Q obtained a sensitivity of 0.92 and a specificity of 0.65.

Patients at the end-of-life, near the time of death, have high levels of sleep disturbances that can be detected early, with better diagnostic accuracy, with the Sleep-Worry-Q. Although from a clinical point of view, the application of the Sleep-Problem-Q may be more advantageous, as it presents good diagnostic accuracy, greater simplicity, and brevity.
