The relationship between repetitive finger movement and quality of life in Parkinson’s disease

Background: Repetitive finger movement significantly impacts daily living activities, but there have been limited studies determining how repetitive finger movement impacts quality of life (QOL) in persons with Parkinson’s disease (PD). The purpose of this study was to determine the relationship between impairment in repetitive finger movement and QOL in persons with PD.

Methods: Eighty-four participants with PD completed a repetitive movement task and the Parkinson’s Disease Questionnaire (PDQ). Structural equation modeling was used to determine the relationship between repetitive finger movement outcome measures of amplitude and movement rate difference and the domains of the PDQ.

Results: Including all repetitive finger outcome measures with demographic variables produced the strongest model for predicting QOL.

Discussion: Repetitive finger movement is associated with QOL, but more research is needed to better understand the relationship between repetitive finger movement variables and each specific QOL domain.     

Emotional complexity and its effect on psychological distress as a function of chronological age and subjective distance-to-death

Objectives: In light of mixed evidence regarding the associations between age, emotional complexity, and psychological distress, this study examined emotional complexity and its effect on psychological distress as a function of age and subjective distance-to-death.

Method: A sample of 188 participants (age range = 29–100) rated their subjective distance-to-death and psychological distress, and reported their emotions across 14 days.

Results: Emotional complexity was unrelated to age, but negatively related to feeling closer to death. Moreover, emotional complexity was negatively related to psychological distress among those feeling closer to death.

Conclusion: Results suggest that when death is perceived to be nearer, emotional complexity is hampered, yet becomes relevant in buffering psychological distress.     

Spinocerebellar ataxia type 3 presenting with writer's cramp without ataxia

Aim of the study: Spinocerebellar ataxia type 3 is the most common cause of autosomal dominant inherited ataxia worldwide.

Material and methods: Clinically, it exhibits wide phenotypic variability. Presentation as isolated dystonia is exceptional.

Results: Here, the case of a woman with writers cramp without ataxia is presented as a paucisymptomatic manifestation of this disease.

Conclusions: This association has not been described to date and extends the clinical variability of the disease.     

Nerve root anomalies detected intra-operatively technical nuances towards achieving a successful surgical outcome: our experience of three case reports at a tertiary level centre

Objective: Analysis of three case reports of nerve root anomalies detected intra-operatively and its implications.

Design: Data collected during one year prospective non-randomised study using hospital records.

Setting: Single tertiary care centre.

Subjects: 3 patients in one year period.     

A light in a sea of darkness: the moderating role of emotional complexity in the PTSD symptoms-successful aging association

Objectives: This study aimed to assess the underexplored effects of posttraumatic stress disorder (PTSD) symptoms on objective and subjective successful aging and to inquire whether emotional complexity moderates these effects.

Methods: Community-dwelling older adults (N = 127, mean age = 67.86, SD = 11.07) rated their PTSD symptoms and completed measures of objective and subjective successful aging. They further reported their emotions on a daily basis over 14 days.

Results: After controlling for background characteristics, self-rated health and cumulative lifetime adversity, results showed that higher PTSD symptoms were related to less successful aging, both objective and subjective. However, this relationship existed only amongst older adults with low emotional complexity, but not amongst those with high emotional complexity.

Conclusion: The findings suggest that high emotional complexity buffers against the negative effects of PTSD symptoms on successful aging. Interventions that empower emotional complexity amongst traumatized older adults may attenuate these negative effects.     

Levodopa,placebo and rotigotine change biomarker levels for oxidative stress

Introduction: Homocysteine increase and glutathione derivative cysteinyl-glycine fall are indirect biomarkers for oxidative stress, for instance due to dopamine D₁ receptor stimulation.

Objectives: To investigate the influence of the D₁ receptor agonists levodopa and rotigotine compared with placebo on homocysteine and cysteinyl-glycine in plasma of patients with Parkinson’s disease.

Methods: Patients received 100 mg levodopa, 4 mg rotigotine or placebo. Cysteinyl-glycine and homocysteine were measured every 30 min over three hours.

Results: Homocysteine rose during levodopa- and placebo administration. Rotigotine had no effect. Cysteine-glycine only increased after placebo- but not after levodopa- or rotigotine.

Discussion: Homocysteine elevation results from hepatic and gastrointestinal methylation processes. Transdermal rotigotine circumvents these methylation locations. Turnover of segregated alkyl residuals from rotigotine serves as methyl group donors, which counteract homocysteine increment. The placebo-related cysteinyl-glycine increase results from reduced free radical exposure. Low levodopa dosing and antioxidants in the rotigotine patch matrix prevented cysteinyl-glycine fall.     

Do depressive symptoms predict mortality in older people?

Context: Depressive symptoms are common in older persons, and may predict mortality.

Objectives: To determine: (1) If depressive symptoms predict mortality; (2) If there is a gradient in this effect; and (3) Which depressive factors predict mortality.

Population: In 1991–1992, 1751 community-dwelling older persons, sampled from a population-based registry, were interviewed.

Measures: The Center for Epidemiologic Studies – Depression (CES-D), age, gender, the Modified Mini-Mental State Examination, self-rated health, and functional status.

Outcome measure: Time to death.

Analysis: Those scoring 16+ on the CES-D were considered depressed. To determine if a gradient was present, the CES-D was treated as a continuous variable. Four depressive factors from the CES-D (depressed affect, positive affect, somatic, and interpersonal) were analyzed. Cox regression models were constructed.

Results: The mortality in those with depressive symptoms was higher in those without depressive symptoms (Hazard Ratio of 1.71, p < 0.001, Log rank test). In multivariable models, this association was no longer significant after accounting for self-rated health and functional status. There was a gradient in risk of mortality across the range of the CES-D. Somatic factors, depressed affect, and positive affect were all associated with mortality in bivariate analyses, but not in multivariable models adjusting for functional status. Interpersonal factors were not associated with mortality.

Conclusions: Depressive symptoms predict mortality in older persons.     

Assessing family caregiver skill in managing behavioral symptoms of Alzheimer's disease

Objectives: This measurement study operationalized family caregiver skill in managing behavioral symptoms associated with Alzheimer's disease (AD) by testing a Caregiver Assessment of Behavioral Skill-Self-Report (CAB-SR) measure.

Method: A cross-sectional design was used. Caregivers had a family member with possible/probable AD, resided at home with the care recipient and provided the majority of care (N?=?82). The mail-administered assessment included the CAB-SR and other care recipient and caregiver measures.

Results: Preliminary CAB-SR reliability and validity were determined using reliability, factor analytic and correlational procedures.

Conclusion: This measure provides a preliminary assessment of caregiver skill in managing behavioral symptoms of AD and shows promise for use in research and clinical intervention settings.     

Psychometric properties of the Valued Living Questionnaire Adapted to Dementia Caregiving

Objectives: Caring for a relative with dementia is associated with physical and emotional health problems in caregivers. There are no studies analysing the role of personal values in the caregiver stress process.

This study aims to analyse the psychometric properties of the Valued Living Questionnaire Adapted to Caregiving (VLQAC), and to explore the relationship between personal values and stressors, coping strategies and caregiver distress.

Method: A total of 253 individual interviews with caregivers of relatives with dementia were conducted, and the following variables were assessed: personal values, stressors, cognitive fusion, emotional acceptance, depression, anxiety, and satisfaction with life. An exploratory factor analysis and hierarchical regression analyses were carried out.

Results: Two factors were obtained, Commitment to Own Values and Commitment to Family Values which explain 43.42% of variance, with reliability coefficients (Cronbach's alpha) of .76 and .61, respectively. Personal values had a significant effect on emotional distress (depression and anxiety) and satisfaction with life, even when controlling for socio-demographic variables, stressors and coping strategies.

Conclusion: Results suggest that the personal values construct of dementia caregivers is two-dimensional. The personal values of the caregivers play an important role in accounting for distress and satisfaction with life in this population.     

Possible error in the Danish version of the WHO Quality of Life (WHOQOL-BREF) Questionnaire

Background: The WHOQOL-BREF is widely used to measure quality of life.

Aims: The goal of the present study was to use the questionnaire in a doctoral study.

Methods: We studied all the instructions provided by the WHO.

Results: In the Danish version of the WHOQOL-BREF there is a discrepancy between the negatively phrased question 9 and both the syntax file and the verbal instructions for coding the data provided by the WHO.

Conclusions: This is a notification of possible error interpretations in projects that use the questionnaire. This could be corrected by manual correction in the coding process or by changing the negatively phrased question 9.     

Internal decompression for spinal stenosis (IDSS) for decompression and use of interlaminar dynamic device (CoflexTM) for stabilization in the surgical management of degenerative lumbar canal stenosis with or without mild segmental instability: our initial results

Introduction: Internal decompression of spinal stenosis (IDSS) and Posterior dynamic stabilization (PDS) form a bridge between decompression laminectomy alone and rigid fusion, by attempting to sustain beneficial effects of decompression and stabilization in an attempt to prevent bad effects of relentless degeneration.

Objective: To evaluate the clinical outcome in operated patient of posterior dynamic stabilization.

Design: Data were collected over 1 year in prospective, nonrandomized follow-up study using outcome scales.

Setting: Single surgeon, tertiary care centre in Mumbai, India.

Described here is the operative technique of posterior dynamic stabilization using CoFlex^TM and clinical outcome of 67 consecutive patients using Visual Analogue Scale and Oswestry Disability Score.     

DNA methylation of imprinted loci of autosomal chromosomes and IGF2 is not affected in Parkinson’s disease patients’ peripheral blood mononuclear cells

Objective: Genomic imprinting is an epigenetic phenomenon that results in differential expression of alleles, depending on their parental origin. The functional significance of DNA methylation in genomic imprinting has been widely investigated, and to date, approximately 100 imprinted genes have been identified in humans.

Methods: To investigate whether the methylation status of these ‘known’ imprinting genes was associated with Parkinson’s disease (PD), we analyzed the methylation profiles of all ‘known’ imprinted genes using the Illumina 450K methylation chip. Samples were derived from mononuclear blood cells of 17 male Parkinson’s disease patients vs. 21 healthy male individuals and 12 discordant MZ twin pairs.

Results: None of the annotated autosomal genes show changes in DNA methylation between PD individuals and healthy individuals. We further refined our analysis by evaluating the DNA methylation status of the maternally imprinted human gene encoding insulin-like growth factor 2 (IGF2) using bisulfite sequencing PCR (BSP) of DNA derived from 15 PD patients and 9 controls, taking into consideration different dosages of L-dopa.

Conclusion: Our results demonstrated that methylation of IGF2 in PD patients was neither influenced by the dosage of L-dopa treatment nor by the disease itself. Thus, loss or disruption of imprinting in autosomal chromosomes does not seem to be relevant for the pathogenesis of the disease.     

Downward finger displacement distinguishes Parkinson disease dementia from Alzheimer disease

Purpose/Aim of the study: To study finger displacement in patients with Parkinson disease dementia (PDD) and in patients with Alzheimer disease (AD).

Methods: We examined 56 patients with PDD and 35 with AD. Patients were examined during their regular outpatient clinic visit. Finger displacement was measured by observers not actively involved in the study using a creative grid ruler for all PDD and AD patients. Finger displacement was examined by asking patients to point their index fingers toward the grid ruler with the nails facing upward. Patients were asked to maintain the pointing position for 15 s. After 15 s, patients were asked to close their eyes for another 15 s while maintaining the same position. A positive result was downward index finger displacement of ≥5 cm within the 15-second time window with eyes closed.

Results: Of the 56 PDD patients, 53 had bilateral finger displacement of >5 cm. In comparison, of the 35 AD patients, only 1 patient had minimal displacement.

Conclusions: Results of the non-invasive finger displacement test may provide insight, on an outpatient basis, of the integrity of subcortical–cortical circuits. Downward finger displacement, especially bilateral downward displacement, may signal the extensive disruption of subcortical–cortical circuits that occurs in PDD patients.

Self-efficacy for controlling upsetting thoughts and emotional eating in family caregivers

Objectives: Self-efficacy for controlling upsetting thoughts was examined as a predictor of emotional eating by family caregivers of physically and cognitively impaired older adults.

Methods: Adult women (N = 158) providing healthcare assistance for an older family member completed an online survey about caregiving stressors, depressive symptoms, self-efficacy, and emotional eating. A stress process framework was used as a conceptual model to guide selection of variables predicting emotional eating scores.

Results: A hierarchical multiple regression was conducted and the overall model was significant (R² = .21, F(4,153) = 10.02, p < .01); self-efficacy for controlling upsetting thoughts was a significant predictor of caregivers’ emotional eating scores after accounting for IADL, role overload, and depression scores.

Conclusion: These findings replicate previous research demonstrating the relationship between managing cognitions about caregiving and behavioral responses to stressors, and point to the importance of addressing cognitive processes in efforts to improve caregiver health behaviors.     

Neurobrucellosis presenting as clinically definite amyotrophic lateral sclerosis

Purpose/Aim: We describe the first case of a patient with neurobrucellosis presenting with clinically-definite ALS.

Material and methods: A 48-year old male patient, in whom the diagnoses of systemic brucellosis and clinically definite ALS were undoubtedly confirmed and were eventually causally interrelated. The disease-specific antibiotic therapy was unsuccessful to slow the evolution of the motor neuron disease and the patient became non ambulatory over time.

Results: Considering the close temporal association of ALS onset with the systemic Brucella infection and consequent antigenic stimuli, we might suggest that human brucellosis might have triggered a process of motor neuron degeneration in keeping with neurobrucellosis, primarily due to parainfectious mechanism.

Conclusion: Our case helps to shed light on the factors that may trigger or only fasten motor neuron disease manifestations.     

Empathy,and its relationship with cognitive and emotional functions in alcohol dependency

Background: Empathy can be defined as the ability to understand the other’s thoughts and feelings. It contains both cognitive and emotional components.

Aims: The aim of this study was to investigate the empathy ability of patients with alcohol dependency in association with cognitive and emotional functions, after acute detoxification and during long-term abstinence.

Methods: Thirty-three alcohol dependent inpatients that completed a detoxification process and stayed abstinent throughout the study, and 33 healthy comparison subjects that matched the patients for age, gender, and education level were included in the study. All the participants were administered the Facial Emotion Identification Test (FEIT), Facial Emotion Discrimination Test (FEDT), Trail Making Test (TMT), Digit Span Test (DST), Auditory Consonant Trigram Test (ACT), and Empathy Quotient Scale (EQS). All the tests were repeated after 3 months of abstinence.

Results: At the first evaluation conducted after detoxification, patients performed significantly worse than healthy comparisons in almost all tests. At the second evaluation, which was conducted after 3 months of abstinence, the patients improved significantly in all measures, and no significant differences were detected between the patient and comparison groups. There were significant correlations between the test scores and EQS score.

Conclusions: Alcohol dependency has deleterious effects on empathy ability, and cognitive and emotional functions. Those impairments can improve with abstinence. Empathy ability has strong relationships with cognitive and emotional functions.     

Cervical myelitis presenting as occipital neuralgia

Aim: Occipital neuralgia is a common form of headache that is characterized by paroxysmal severe lancinating pain in the occipital nerve distribution.

Methods: The exact pathophysiology is still not fully understood and occipital neuralgia often develops spontaneously. There are no specific guidelines for evaluation of patients with occipital neuralgia.

Result: Cervical spine, spinal cord and posterior neck muscle lesions can induce occipital neuralgia. Brain and spine imaging may be necessary in some cases, according to the nature of the headache or response to treatment.

Discussion: We report a case of cervical myelitis presenting as occipital neuralgia.     

Consumer satisfaction with antipsychotic medication-monitoring appointments: the role of consumer–prescriber communication patterns

Objective: The study was designed to explore patterns of prescriber communication behaviors as they relate to consumer satisfaction among a serious mental illness sample.

Methods: Recordings from 175 antipsychotic medication-monitoring appointments between veterans with psychiatric disorders and their prescribers were coded using the Roter Interaction Analysis System (RIAS) for communication behavioral patterns.

Results: The frequency of prescriber communication behaviors (i.e., facilitation, rapport, procedural, psychosocial, biomedical, and total utterances) did not reliably predict consumer satisfaction. The ratio of prescriber to consumer utterances did predict consumer satisfaction.

Conclusions: Consistent with client-centered care theory, antipsychotic medication consumers were more satisfied with their encounters when their prescriber did not dominate the conversation.

Practice implications: Therefore, one potential recommendation from these findings could be for medication prescribers to spend more of their time listening to, rather than speaking with, their SMI consumers.     

Experiences of self-injury and aggression among women admitted to forensic psychiatric care

Background: Self-injury and institutional violence are well-known characteristics of female forensic psychiatric patients, but research on patients’ experiences of these behaviours is limited.

Aim: The aim of the study was to investigate how female forensic psychiatric patients describe their self-injury and aggression.

Methods: The authors performed qualitative in-depth interviews with 13 female forensic psychiatric inpatients. The interviews were analysed using thematic analysis.

Results: The analysis resulted in three themes describing the process of handling negative thoughts and emotions by using self-injury or aggression towards others and thereby experiencing satisfaction. Both self-injury and aggression were experienced as strategies for emotional regulation. The forensic psychiatric care was perceived as important for the women in developing less harmful strategies for coping with negative thoughts and emotions instead of injuring themselves or others.

Conclusions: Self-injury and aggression are often risk-assessed separately, but results from the present study suggest that these behaviours need a more holistic approach.     

Neurological impairments in hypoxic neonates and lactate levels

Introduction: Metabolic acidosis with increasing lactate concentration develops due to the lack of oxygen in the tissues.

Objectives: The effect of lactic acidosis on neurological development in the first year of life.

Materials and Methods: Our study included 50 newborns with perinatal hypoxia requiring oxygen therapy and 50 healthy newborns. pH, pCO2, pO2, base excess (BE) and lactates from arterialized capillary blood were determined in both groups of newborns, in the first and second hours after birth, and neurological development in the first year of life was estimated.

Results: pH, pCO2, pO2, BE and lactates differed significantly between the groups in the first and second hours after birth p < 0.01. Hypotonia was recorded in 20/50 cases and hypertonia was recorded in 10/50 cases in the first year of life.

Conclusion: Lactate concentration may be an indicator of neurological damage in neonates with perinatal hypoxia.
