Evaluation of anxiety, depression and urinary protein excretion among the family caregivers of advanced cancer patients

Different frying processes stimulate lipid peroxidation and promote changes in the composition of cholesterol, free fatty acids and triglycerides in the commercial clam’s tissues Venerupis decussata

This investigation was aimed to assess and evaluate the effect of frying process with three different oils (corn, olive and margarine) on fatty acids and lipid classes’ composition of clam and their impact on the nutritional value and tissues quality. The results indicated that the contents of saturated, monounsaturated and polyunsaturated fatty acids varied significantly in fried clams and frying oil. Our data demonstrated that all lipid classes’ contents increased significantly after all frying processes. It was concluded that the frying process decreased the n-3/n-6 and DHA+EPA and increased the levels of atherogenic; thrombogenic indices. Additionally, these culinary processes promoted lipid peroxidation through the enhancement of TBARs, PV and FFA. These changes were more significant and intensive after frying with margarine and corn oils followed by virgin olive oil. These results suggest that clam fried with olive oil can be classified as highly nutritive in regard to its lipid content, major fatty acid profile; and nutritional value.

Psychosocial Issues Among Primary Caregivers of Patients with Advanced Head and Neck Cancer - A Mixed-method Study

Objectives:

This study aims to explore the psychosocial issues faced by the primary caregivers of advanced head and neck cancer patients with the primary objective to understand their experiences within social context.

Materials and Methods:

Burden and QOL of caregivers (n = 15) were quantified using Zarit Burden Interview schedule and caregiver quality of life index-cancer (CQOLC), respectively. Primary caregivers (n = 10) were interviewed using semi-structured interview schedule. Thematic analysis was employed to analyse the qualitative data. Descriptive statistics was used for quantitative data.

Results:

Four major themes emerged: (1) Impacts of caregiving, (2) coping with caregiving, (3) caregiver’s appraisal of caregiving and (4) caregiver’s perception of illness. Majority (73.3%) of the caregivers had QOL below 100. The mean CQOLC score was 73.07 (SD 24.17) and most (46.7%) of the caregivers reported mild-to-moderate burden, while 27% had little to no burden. The mean ZBI score was 32.4 (SD 18.20).

Conclusion:

Caregiving impacts the physical, emotional, financial and social aspects of caregiver’s life. Caregivers adopt active coping strategies to overcome the impacts of caregiving. Family acts as a major source of strength to manage the emotional constraints faced by Indian caregivers. Cultural beliefs and values of caregivers influence their appraisal of caregiving situation. Majority of the caregivers experienced mild-to-moderate burden while most of the caregivers scored low on QOL.

Co-abuse of alprazolam augments the hepato-renal toxic effects of methylphenidate

OBJECTIVE:

Methylphenidate (MPH) is a first-line treatment option for attention-deficit hyperactive disorder and narcolepsy. MPH is one of the most abused psychostimulants by the adults and young population to stay awake, perform better, or improve concentration. The scanty reports say that the medical users or abusers mostly consider the administration of benzodiazepines to overcome the adverse effects, i.e., mood- and anxiety-related problems associated with MPH chronic abuse. This work aims to study the effect of alprazolam (ALZ) on MPH-associated adverse effects on liver and kidney.

MATERIALS AND METHODS:

Female Wistar rats (n = 58) were administered with MPH (10, 20, and 40 mg/kg) and ALZ (5, 10, and 20 mg/kg) alone and in combination for 28 days. Bodyweight, feed intake, and water intake were monitored weekly. Parameters related to liver and renal function, oxidative stress, and histopathology were performed to evaluate the toxic impacts on the liver and kidneys.

RESULTS:

ALZ, along with MPH, increased the serum alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatinine, and urea levels. The co-abuse also led to elevated oxidative stress and structural abnormalities in the liver and kidney tissues.

CONCLUSION:

The co-abuse of ALZ has amplified the hepato-renal toxic effects of MPH. Therefore, it is a significant concern for public safety, and their co-abuse must be restricted and discouraged.

How do family-caregivers of patients with advanced cancer provide symptom self-management support? A qualitative study

PURPOSE

The family-caregiver role is of critical importance to the success of symptom-related self-management of patients with advanced cancer. This study examined the perspectives of patients and family-caregivers regarding the role of the family-caregiver in symptom-related self-management support ( SMS).

METHODS

Semi-structured interviews were conducted in patients with advanced cancer experiencing significant symptom burden and their family-caregivers. An inductive content analysis approach was used to analyse data.

RESULTS

Eleven patients and ten family caregivers were included. Identified themes were 1) engaging in specific symptom-related SMS; 2) interacting with health care professionals; and 3) balancing patient need versus expectation. These themes were applicable to both the family-caregiver and patient cohorts, regardless of the individual symptom profile of each patient.

CONCLUSIONS

The role of family-caregivers of patients with advanced cancer is complex and varied in providing symptom-related SMS at home; often requiring family-caregivers to have diverse knowledge and skills in the management of a range of cancer-related symptoms. Health care professionals can support family-caregivers by anticipating needs, tailoring evidence-based information to those needs, and ensuring family-caregivers have an appropriate contact point for advice or help.

Urine cortisol-creatinine and protein-creatinine ratios in urine samples from healthy dogs collected at home and in hospital

Background

Recently, urine protein:creatinine ratios (UPC) were shown to be lower in urine samples from dogs collected at home (AH) as compared to those collected in hospital (IH). Stress‐inducing procedures and travel to the hospital have been hypothesized to cause prerenal proteinuria.

Objectives

Evaluate patient stress using urine cortisol:creatinine ratios (UCCr) and correlate UCCr to UPC in urine samples obtained AH and IH.

Animals

Thirty‐six healthy, client‐owned dogs.

Methods

Prospective, non‐masked study. Two voided urine samples were obtained (AH and IH). Complete urinalysis as well as UPC and UCCr were performed. Clients graded their dogs' stress level AH, in transport, and IH.

Results

The UCCr was significantly higher in IH samples than in AH samples (P < .0001), but UPC was not significantly different between AH and IH urine samples (P = .14). In all samples and in both collection settings, UCCr was not significantly correlated with UPC. Travel time and time IH were not correlated with change in UCCr or UPC. In 8 dogs with borderline or overt proteinuria, no significant difference was found in UPC between settings, but UCCr was significantly higher in IH samples.

Conclusions and Clinical Importance

The UPC was not higher when measured in urine samples collected IH compared to AH. Dogs had higher UCCr IH, but UCCr was not associated with UPC. Stress, as estimated by UCCr, did not affect proteinuria. Further evidence is needed to support the claim that stress may result in proteinuria in healthy dogs.

Validation of the caregiver oncology quality of life questionnaire in Portuguese caregivers of myeloma patients

OBJECTIVE

Cancer diagnosis affects patients, their families, and their caregivers in particular. This study focused on the validation of the CareGiver Oncology Quality of Life (CarGOQoL) questionnaire in Portuguese caregivers of patients with multiple myeloma, from the caregiver's point of view.

METHOD

This was a cross-sectional study with 146 caregivers of patients with multiple myeloma from outpatient medical oncology and clinical hematology consultations from five hospitals in north and central Portugal. Participants were assessed on quality of life (QoL), psychological morbidity and social support.

RESULT

The Portuguese version maintains 17 of the original 29 items version, maintaining general coherence and a dimensional structure that is clinically interpretable. Reliability findings indicated good internal consistency for the total scale (0.86) and respective subscales (0.75 to 0.88), which is in agreement with the alpha values from the previous CarGOQoL validation study for the corresponding subscales (0.74 to 0.89) and total scale (0.90).

SIGNIFICANCE OF RESULTS

The CarGOQoL is a reliable and valid tool for clinical trials and intervention programs to assess QoL in caregivers of myeloma patients. Future studies should validate the adapted version in caregivers of other types of cancer patients including other chronic diseases.

Advanced cancer caregiving as a risk for major depressive episodes and generalized anxiety disorder

OBJECTIVE

Caregivers of advanced cancer patients provide extensive care associated with high levels of caregiver distress. The degree to which cancer caregiving increases caregivers' risk for a psychiatric disorder is unknown. The current study examines whether advanced cancer caregiving poses distinct risks for initial and recurrent major depressive episodes (MDEs) and generalized anxiety disorder (GAD) relative to the general population.

METHODS

Caregivers of advanced cancer patients (N = 540) from Coping with Cancer were compared to general population controls (N = 9282) from the National Comorbidity Survey Replication. The general population comparison sample was propensity-weighted to be demographically similar to the caregiver sample.

RESULTS

Caregivers of advanced cancer patients were more likely than individuals in the general population to have an initial MDE (OR = 7.7; 95% CI, 3.5-17.0; P < .001), but no more likely than the general population to have a recurrent MDE (OR = 1.1; 95% CI, 0.6-2.1; P = .662). Caregivers were also more likely than the general population to have GAD (OR = 3.0; 95% CI, 1.9-4.8; P < .001) and comorbid MDE and GAD (OR = 2.5; 95% CI, 1.1-5.9; P = .038).

CONCLUSIONS

The increased risk of meeting diagnostic criteria for current MDE and GAD and comorbid MDE and GAD associated with advanced cancer caregiving highlights the degree of emotional burden among cancer caregivers. Clinical services that assess, prevent, and treat depression and anxiety in cancer caregivers are needed to reduce the burden of caregiving and improve the mental health of this growing population.

Psychological distress and loneliness in caregiver of advanced oncological inpatients

The objective of this study is to compare and examine the relationships between levels of loneliness, anxiety, depression, and other variables on primary caregivers and cancer inpatients. The study involved 100 Turkish primary caregivers of inpatients with advanced or terminal stages of cancer. Loneliness and anxiety scores were significantly higher for the primary caregivers of inpatients with terminal stage of cancer than primary caregivers of inpatients with advanced stage of cancer. Excluding the cancer stage, loneliness and anxiety were primarily associated with the socio-demographic factors of primary caregivers rather than the characteristics of patients.

Evaluation of oxidative and antioxidative parameters in generalized anxiety disorder

Generalized anxiety disorder (GAD) is a prevalent psychiatric disorder. The exact causes of GAD still unknown, in addition to neurochemical and neuroanatomic disorders, genetic and environmental factors are discussed in etiology. In our study we aimed to evaluate the oxidative metabolism's status and investigate the role of oxidative metabolites in GAD. Blood samples were taken from enrolled subjects in appropriate way and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were studied in Harran University Biochemistry Labs. Results were compared between groups. The patients' TOS and OSI levels were significantly higher than control group. The patients' TAS levels were significantly lower than controls'. According to our findings, oxidative stress mechanism might have a role in GAD pathophysiology. In the future, total antioxidants may be used as a biologic marker in GAD etiology but more research is needed.

Oxidative imbalance and anxiety disorders

The oxidative imbalance appears to have an important role in anxiety development. Studies in both humans and animals have shown a strong correlation between anxiety and oxidative stress. In humans, for example, the increased malondialdehyde levels and discrepancies in antioxidant enzymes in erythrocytes have been observed. In animals, several studies also show that anxiety-like behavior is related to the oxidative imbalance. Moreover, anxiety-like behavior can be caused by pharmacological-induced oxidative stress. Studies using knockout or overexpression of antioxidant enzymes have shown a relationship between anxiety-like behavior and oxidative stress. Related factors of oxidative stress that could influence anxious behavior are revised, including impaired function of different mitochondrial proteins, inflammatory cytokines, and neurotrophic factors. It has been suggested that a therapy specifically focus in reducing reactive species production may have a beneficial effect in reducing anxiety. However, the neurobiological pathways underlying the effect of oxidative stress on anxiety symptoms are not fully comprehended. The challenge now is to identify the oxidative stress mechanisms likely to be involved in the induction of anxiety symptoms. Understanding these pathways could help to clarify the neurobiology of the anxiety disorder and provide tools for new discovery in therapies and preventive strategies.

What does the informal caregiver of a terminally ill cancer patient need? A study from a cancer centre

Aims:

To assess the needs of informal caregivers of terminally ill cancer patients.

Materials and Methods:

Fifty four informal caregivers of patients registered in our palliative care service were interviewed 3–6 months after the death of the patient with the help of a semistructured questionnaire covering the physical, medical, psychological, social, and information domains.

Results:

Most of the caregivers were middle aged and had no prior experience of care giving. The caregivers were satisfied by the information and medical support provided to them by their treatment team. Most had an “emergency plan”. Caregivers had unmet needs including homecare, psychological support, and financial help.

Conclusions:

informal caregivers provide most of the nursing and psychological support to the patient. However, palliative care services need to recognize that the caregiver too may need psychological and technical support.

The cancer family caregiving experience: an updated and expanded conceptual model

OBJECTIVE

The decade from 2000 to 2010 was an era of tremendous growth in family caregiving research specific to the cancer population. This research has implications for how cancer family caregiving is conceptualized, yet the most recent comprehensive model of cancer family caregiving was published ten years ago. Our objective was to develop an updated and expanded comprehensive model of the cancer family caregiving experience, derived from concepts and variables used in research during the past ten years.

METHODS

A conceptual model was developed based on cancer family caregiving research published from 2000 to 2010.

RESULTS

Our updated and expanded model has three main elements: 1) the stress process, 2) contextual factors, and 3) the cancer trajectory. Emerging ways of conceptualizing the relationships between and within model elements are addressed, as well as an emerging focus on caregiver-patient dyads as the unit of analysis.

CONCLUSIONS

Cancer family caregiving research has grown dramatically since 2000 resulting in a greatly expanded conceptual landscape. This updated and expanded model of the cancer family caregiving experience synthesizes the conceptual implications of an international body of work and demonstrates tremendous progress in how cancer family caregiving research is conceptualized.

Experimental depression induces renal oxidative stress in rats

Depression has been associated to inflammatory and oxidative events. Previous report has shown renal oxidative stress in patients with depression. In order to analyze if depressive status is related to renal oxidative and inflammatory events, Sprague Dawley rats were submitted to forced swimming test (FST) and the renal oxidative metabolism, monocyte-macrophage infiltration and Angiotensin II (Ang II) expression were determined. Rats were submitted to FST daily (30 min) for 15 days. Motor activity was analyzed before FST. Kidney sections were homogenized to measure nitric oxide (NO), malondialdehyde (MDA), reduced glutathione (GSH) and catalase activity by enzymatic and biochemical methods. Renal frozen sections were studied for superoxide anion (O2-), monocyte/macrophage infiltration and Ang II expression by histochemical and immunofluorescence methods. In addition, three groups of FST rats were treated with losartan, sertraline or water for 18 days with further renal O2-analysis. In the FST group, struggle time, motor activity, food intake and body weight gain were found decreased. Increased number of glomerular, interstitial and tubular O2-positive cells was observed in FST rats. High renal content of nitrite/nitrate (NO), MDA and decreased amount of GSH were found in FST rats. Values of renal ED-1 or Ang II positive cells in FST rats remained similar to controls; however, AT1 receptor blocking (losartan) and sertraline reduced both depressive-like behavior and renal O2-expression. These data suggests that depression-like behavior in rats is involved in kidney oxidative stress probably mediated by AT1 receptors.

Oxidative stress in anxiety and comorbid disorders

Anxiety disorders, depression, and alcohol use disorder are common neuropsychiatric diseases that often occur together. Oxidative stress has been suggested to contribute to their etiology. Oxidative stress is a consequence of either increased generation of reactive oxygen species or impaired enzymatic or non-enzymatic defense against it. When excessive it leads to damage of all major classes of macromolecules, and therefore affects several fundamentally important cellular functions. Consequences that are especially detrimental to the proper functioning of the brain include mitochondrial dysfunction, altered neuronal signaling, and inhibition of neurogenesis. Each of these can further contribute to increased oxidative stress, leading to additional burden to the brain. In this review, we will provide an overview of recent work on oxidative stress markers in human patients with anxiety, depressive, or alcohol use disorders, and in relevant animal models. In addition, putative oxidative stress-related mechanisms important for neuropsychiatric diseases are discussed. Despite the considerable interest this field has obtained, the detailed mechanisms that link oxidative stress to the pathogenesis of neuropsychiatric diseases remain largely unknown. Since this pathway may be amenable to pharmacological intervention, further studies are warranted.

An exploration into physiological and self-report measures of stress in pre-registration doctors at the beginning and end of a clinical rotation

The first year practising medicine, pre-registration, is considered to be a stressful time for junior doctors. The aims of this study were to explore how levels of psychological distress were affected by changes in the working environment and to examine these effects across subjective (i.e. self-report) and objective (i.e. stress hormone cortisol) indices of psychological distress. A cohort of 36 pre-registration house officers (males = 15) completed a battery of psychosocial measures and collected salivary samples for the measurement of diurnal cortisol at the beginning and end of a 3-4-month clinical rotation with the assumption that the end of a rotation would be less stressful than the beginning. Results from the self-report measures remained constant over the two-time points suggesting no perceived change in emotional well-being on a subjective level. However, there is some evidence of neuro-endocrine changes across the two time points suggestive of hypothalamic-pituitary-adrenal axis dysregulation. In particular, there was a significant difference between the cortisol awakening rise with the greatest rise seen at the beginning of a rotation. In addition, the daily cortisol decline (diurnal slope) was also significantly less at this test time. These findings have implications for the discord apparent between self-report and physiological measures of psychological stress.
