RESUMO
The vitamin C deficiency disease scurvy is characterised by musculoskeletal pain and recent epidemiological evidence has indicated an association between suboptimal vitamin C status and spinal pain. Furthermore, accumulating evidence indicates that vitamin C administration can exhibit analgesic properties in some clinical conditions. The prevalence of hypovitaminosis C and vitamin C deficiency is high in various patient groups, such as surgical/trauma, infectious diseases and cancer patients. A number of recent clinical studies have shown that vitamin C administration to patients with chronic regional pain syndrome decreases their symptoms. Acute herpetic and post-herpetic neuralgia is also diminished with high dose vitamin C administration. Furthermore, cancer-related pain is decreased with high dose vitamin C, contributing to enhanced patient quality of life. A number of mechanisms have been proposed for vitamin C's analgesic properties. Herein we propose a novel analgesic mechanism for vitamin C; as a cofactor for the biosynthesis of amidated opioid peptides. It is well established that vitamin C participates in the amidation of peptides, through acting as a cofactor for peptidyl-glycine α-amidating monooxygenase, the only enzyme known to amidate the carboxy terminal residue of neuropeptides and peptide hormones. Support for our proposed mechanism comes from studies which show a decreased requirement for opioid analgesics in surgical and cancer patients administered high dose vitamin C. Overall, vitamin C appears to be a safe and effective adjunctive therapy for acute and chronic pain relief in specific patient groups.

AIM: To examine the relationship of the pain severity scores with demographic variables (age, gender, and ethnicity) and with the frequency of falls, fatigue, and depression in a very large New Zealand sample of people over 65 years assessed using the Home Care International Residential Assessment Instrument. BACKGROUND: Pain is reported to be highly prevalent in older people yet it is poorly correlated with tissue damage. There is convincing evidence that it is related to depression and some evidence of its relationship with fatigue and falls. DESIGN: This is a cross-sectional study examining a national cohort assessed on referral for a needs assessment for access to publicly funded service provision or support. METHOD: Participants were 45,418 adults aged over 65 years referred for a mandatory needs assessment between 2012-2014. All variables analysed were drawn from the Home Care International Residential Assessment Instrument. Univariate descriptive statistics were used to characterize the sample in relation to the association of severe pain with age, gender, and ethnicity and with the key variables of interest: falls, fatigue, and depression. Logistic regression models were used to examine the relationship of the presence or not of severe pain with the other key health-related variables: falls, fatigue, and depression, respectively, after controlling for the presence of age, gender, and ethnicity. Odds ratios are reported to quantify the difference in risk with increasing severity of falls, fatigue, and depression. RESULTS: The mean age of the cohort was 82.48 years (SD 7.48) and 48.5% of the sample reported experiencing daily pain. The rates of severe daily pain were 12%-18% with those in the 65-74 years group having the highest reported rate of severe pain (18%) and a gradual decrease in severe pain with age. After co-varying for age, ethnicity, and gender, the presence of severe daily pain was predicted by increasing frequency of falls and fatigue and having current depression. While two-thirds reported their pain control was adequate, a third reported that their pain control was not adequate despite adhering to a therapeutic regime. CONCLUSION: The study highlights how pervasive pain is in this group and its correlation with falls, fatigue, and depression. While the effect sizes were relatively small the results may be clinically significant and it may be clinically important that the presence of pain in older people could indicate the need for further nursing assessment in relation to falls, fatigue, and depression.

WHAT IS KNOWN ON THE SUBJECT?: Rates of antidepressant prescribing have been increasing. Antidepressants are not effective for many people. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Participants described how in order to receive help they had to engage with a medical pathway in which their experiences were constructed as arising from a biochemical deficit. Antidepressant prescribing was identified as being the only option available and was associated with stigma. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health nurses have a role to play in providing treatment options for those experiencing depression. Mental health nurses need to provide evidence-based information about antidepressants support those experiencing depression to make informed choices. ABSTRACT: Introduction There are increased prescribing rates of antidepressants associated with an increase in the diagnosis of depression. However, antidepressants are not effective for many people. There is a gap in the existing literature for a synthesis of the experiences of those with lived experience of antidepressant use to better understand their use and impact given their ubiquitous use in mental health, primary care and other secondary and tertiary care settings. Mental health nurses play direct or indirect roles in both advocating for antidepressant use and monitoring adherence. Aims To identify how people prescribed antidepressants describe their experiences of the medication including its discontinuation? Method A meta-synthesis of qualitative studies examining patients' experiences of antidepressant medication. Ovid MEDLINE, EMBASE, PsychINFO and Cochrane Library databases were searched in May 2021. One reviewer screened titles and abstracts. Two reviewers independently reviewed the retrieved papers for eligibility and data extraction. The data synthesis was conducted using thematic analysis. Two reviewers independently conducted quality appraisals. Results Twenty-seven studies with a total of 2937 participants were identified for inclusion in this review. Four themes were identified across the studies: the only option available; stigma associated with 'biochemical deficit' not myself and the vicious cycle. Implications for practice Those seeking treatment for depression need to be provided with treatment options and evidence-based information about anti-depressants to provide them with the opportunity to make informed choices.

BACKGROUND: Conflicting findings prevail about pain in older persons with cognitive impairment. There is evidence of changed pain perception; however, pain is also underrecognized. Pain and cognitive impairment were examined in a national cohort of older persons assessed using the Home Care International Residential Assessment Instrument (interRAI-HC). METHODS: Participants were 41 459 aged 65+ years receiving a mandated needs assessment to access publicly funded services. InterRAI-HC pain severity and Cognitive Performance Scale analyses covaried for age, gender, and ethnicity. RESULTS: Milder pain prevalence increased with age, whereas daily severe-excruciating pain prevalence decreased with age. Daily severe-excruciating pain was reported by 18% of cognitively intact individuals decreasing to 8% in the severe cognitive impairment group. This relationship remained after covarying for age, sex, and ethnicity. Differences among dementia subtypes were found. CONCLUSION: Although severe pain reports decrease with increasing age and cognitive impairment, more nuanced research covarying for dementia severity and subtype is required.

BACKGROUND: There is evidence that chronic pain is not recognised or managed effectively in older people. It is important to examine how older people cope with this because of the impact it can have on their quality of life and mortality. It will also enable nurses to work with older people to support effective coping skills and provide information on other useful coping strategies. OBJECTIVES: To examine how older people cope with non-malignant chronic pain. DESIGN: This is a qualitative meta-synthesis using Confidence in the Evidence from Reviews of Qualitative Research developed by Grading of Recommendations Assessment Development and Evaluation working group to evaluate the strength of the evidence. DATA SOURCES: PubMed and Ovid Medline from 1995 to 2015. REVIEW METHODS: Following a systematic search strategy all papers were assessed in relation to inclusion criteria and quality. Only qualitative studies were included. Themes were extracted from each study and a meta-synthesis conducted before completing an evaluation of confidence in the findings. RESULTS: Seventeen primary studies were included in the meta-synthesis. Three meta-themes were identified: 'adjusting to the inevitable', 'doing it my way without medication' and 'the importance of support in managing the struggle'. There was high confidence in the evidence for 'doing it my way without medication' and moderate confidence in the evidence for the other two meta-themes. CONCLUSION: Given that the participants in the primary studies were generally wary of health professionals and stoic in their response to pain, it is important for nurses to communicate in ways that engage older people and ensure their independence and sense of control remains intact. Identification of current coping strategies will enable the nurse and the older person to work together to assess their effectiveness and to adapt these if more effective coping is required.
