The mechanical response to hockey-specific running gait: implications for the objective monitoring of (p)rehabilitation

Field hockey is characterized by a unique dribbling position which has been associated with a prevalence of low back pain and lumbar injury. To quantify the biomechanical response of the hockey-specific running gait, twelve field hockey players completed treadmill running at speeds of 6, 9 and 12 km·hr-1 with a normal running gait and whilst manipulating the hockey stick to replicate dribbling. Mechanical loading was quantified using tri-axial accelerometery at L4, and muscular activity was measured for biceps femoris (BF), gluteus medius (GM) and quadratus lumborum (QL) of each limb. Running with the stick elicited greater mechanical loading in the medio-lateral (p = 0.001) and antero-posterior (p = 0.003) planes, and increased peak (p = 0.004) and mean (p = 0.002) EMG response of QL (p = 0.004). The greater planar mechanical loading and QL activation in response to hockey-specific running technique support epidemiological observations of lower back pain prevalence. The sensitivity of uni-axial mechanical loading to the hockey-specific running posture provides an efficacious means of objectively monitoring mechanical loading in-vivo, whilst the QL activation response has implications for (p)rehabilitative interventions. Running posture and speed can be considered as discrete progressions when considering training load.

The IBER study: a feasibility randomised controlled trial of imagery based emotion regulation for the treatment of anxiety in bipolar disorder

BACKGROUND

Intrusive mental imagery is associated with anxiety and mood instability within bipolar disorder and therefore represents a novel treatment target. Imagery Based Emotion Regulation (IBER) is a brief structured psychological intervention developed to enable people to use the skills required to regulate the emotional impact of these images.

METHODS

Participants aged 18 and over with a diagnosis of bipolar disorder and at least a mild level of anxiety were randomly assigned (1:1) to receive IBER plus treatment as usual (IBER + TAU) or treatment as usual alone (TAU). IBER was delivered in up to 12 sessions overs 16 weeks. Clinical and health economic data were collected at baseline, end of treatment and 16-weeks follow-up. Objectives were to inform the recruitment process, timeline and sample size estimate for a definitive trial and to refine trial procedures. We also explored the impact on participant outcomes of anxiety, depression, mania, and mood stability at 16-weeks and 32-weeks follow-up.

RESULTS

Fifty-seven (28: IBER + TAU, 27: TAU) participants from two sites were randomised, with 50 being recruited within the first 12 months. Forty-seven (82%) participants provided outcome data at 16 and 32-weeks follow-up. Thirty-five participants engaged in daily mood monitoring at the 32-week follow-up stage. Retention in IBER treatment was high with 27 (96%) attending ≥ 7 sessions. No study participants experienced a serious adverse event.

DISCUSSION

The feasibility criteria of recruitment, outcome completion, and intervention retention were broadly achieved, indicating that imagery-focused interventions for bipolar disorder are worthy of further investigation.

The problem with picking: Permittance, escape and shame in problematic skin picking

OBJECTIVES

Problematic skin picking (SP) is a poorly understood experience characterised by a drive to pick the skin and related psychosocial impact. In the DSM-5, problematic SP is classified as 'excoriation (skin picking) disorder'. The aim of this article is to present a rare qualitative perspective on the lived experience of problematic SP, prioritising participants' voices and sense-making.

DESIGN

An in-depth qualitative study of individuals who self-identified as picking their skin problematically and experienced related distress.

METHODS

Seventeen UK-based participants were recruited online and interviewed about their SP. Participants were given choice of interview modality, including instant messenger platforms, telephone, email and Skype, to maximise comfort and improve the accessibility of the study. Transcripts were analysed using thematic analysis.

RESULTS

Three themes offering novel insight into the phenomenology of participants' SP are highlighted and explored: (1) how cognitions and circumstances drove and permitted SP, (2) how participants 'zoned out' while SP and the escape or relief that this attentional experience offered and (3) participants' feelings of shame and distress in how they felt their SP may appear to others.

CONCLUSIONS

This study contributes in-depth and novel ideas to the understanding of SP phenomenology and identifies how environmental factors, cognitions, contextual distress and shame may be considerations in therapeutic intervention. It presents the complexity of SP sense-making and demonstrates the need for individual formulation.

Response to Comment on "A global environmental crisis 42,000 years ago"

Our paper about the impacts of the Laschamps Geomagnetic Excursion 42,000 years ago has provoked considerable scientific and public interest, particularly in the so-called Adams Event associated with the initial transition of the magnetic poles. Although we welcome the opportunity to discuss our new ideas, Hawks' assertions of misrepresentation are especially disappointing given his limited examination of the material.

619 Is the Subdivision of Thy3 Nodules Needed? An Audit Reviewing the Management of Thy3 Nodules, and the Associated Malignancy Rates

Introduction

Following the 2014 update to the BAETS thyroid nodule cytology guidance, the management of Thy3 lesions was modified by subdivision into Thy3a and Thy3f categories. Both lesions remain indeterminate but are proposed to have differing risks of malignancy when counselling patents: these risks have been called into question by subsequent data.

Aim

This Audit aimed to review the management of Thy3 (Thy3a and Thy3f) cytological diagnoses, within an NHS Trust, and compare this to the BAET Guidance 2014. Further, malignancy rates for Thy3a and Thy3f cytology were made over the calculated over the time period.

Method

A retrospective Audit looking at 118 patients with a Thy3 cytology identified between 2014 and 2019. Data separated into data pre-2015 and 2015 onwards.

Results

In 2014, 29% of Thy3a nodules were managed in line with 2014 BAETS guidance. This improved to 34% from 2015. Meanwhile, Thy3f diagnoses were managed mostly in favour of the BAETS guidelines – 83% in 2014 and 92% 2015 onwards. The malignancy rates found, amongst all 118 patients, were 17.2% and 14.8% for Thy3f and Thy3a nodules respectively.

Conclusions

At this institution, Thy3 cytological diagnoses, regardless of classification into Thy3a or Thy3f, were largely treated in the same way (by a diagnostic hemi-thyroidectomy). The management of the nodules may reflect a variety of factors, including how comfortable patients and surgeons are when handling uncertainty. With malignancy rates for both Thy3a and Thy3f nodules being much the same, it is not surprising that they are managed in a similar way.

Therapists' and non-therapists' constructions of heterosex: A qualitative story completion study

OBJECTIVES

Little research has examined the discourses that shape therapists' sense-making around heterosex. This paper explores the discourses of sexuality and gender underpinning therapists' and non-therapists' responses to a sexual experimentation scenario in a heterosexual relationship. It also considers the value of the novel technique of story completion (SC), in which participants are asked to write a story in response to a hypothetical scenario, for qualitative psychology and psychotherapy research.

DESIGN

This research used a comparative SC design (Kitzinger & Powell, 1995). Participants were sequentially presented with and invited to complete two story stems: one in which a male character suggested 'trying something new' to his female partner and one in which the female character made the suggestion. The stems were otherwise identical.

METHODS

A total of 100 SCs were written by 49 (28 female; 21 male) therapists and 51 (29 female; 22 male) non-therapists. Participants were recruited mainly via UK-based email lists and Facebook groups, and therapeutic training organizations, and the data were analysed using a feminist post-structuralist thematic analysis (Braun & Clarke, 2006).

RESULTS

Both groups of participants drew on heteronormative discourses of sexuality and gender to make sense of the stem. Engaging in sexual experimentation was often depicted as a demonstration of being normal. In some stories written by women, sex was framed as a site for negotiating 'equality' and reciprocity in relationships. Therapists were more likely than non-therapists to frame 'difficulties' within relationships as opportunities for personal growth and increased emotional depth, and their stories included greater emotional complexity.

CONCLUSION

These findings raise questions about practitioner training and whether it results in therapists drawing on narrow and restrictive discourses of heterosex in clinical practice.

PRACTITIONER POINTS

Training on sexual issues is largely absent from non-specialist practitioner training courses, which potentially means therapists are ill-equipped to respond to clients' anxiety about sexual issues. Evidence from this and other research indicates that therapists' sense-making around heterosexual sexual relationships is underpinned by narrow and restrictive discourses that entrench traditional gender relations and limit sexual agency. Psychologists are increasingly taking up positions of clinical leadership and are looked to for models of best practice. Drawing on theorizations of sexual difficulties, and of anxieties about sexual practice, that challenge traditional gender and heteronorms, and the commodification and medicalization of sex, is important for effective psychological leadership relating to the treatment of sexual issues and the furthering of social justice agendas.

Impact of psychiatric medication co-exposure on Neonatal Abstinence Syndrome severity

BACKGROUND

Among opioid-exposed infants, psychiatric medication co-exposure is common. Our objective was to compare Neonatal Abstinence Syndrome (NAS) outcomes based on individual psychiatric medication co-exposures.

METHODS

A retrospective study of 744 opioid-exposed mother-infant dyads from a single institution was performed. Mothers on pharmacotherapy with methadone or buprenorphine at delivery were included. Data were collected on maternal demographics, psychiatric medication use, and NAS outcomes, including any medication treatment, adjunctive medication treatment, length of hospital stay (LOS), and opioid treatment days. The extent to which individual psychiatric medication and polypharmacy exposure were associated with NAS outcomes was assessed using multivariable regression.

RESULTS

Fifty-four percent of the mothers were on ≥1 psychiatric medication, with 32% on ≥2 or psychiatric medications (polypharmacy group). In adjusted models, polypharmacy exposure was associated with longer LOS (β = 4.31 days, 95% CI 2.55-6.06) and opioid treatment days (β = 3.98 days, 95% CI 2.24-5.72) and more treatment with adjunctive medication for NAS (aOR = 2.49, 95% CI 1.57-3.95). Benzodiazepines were associated with longer LOS (β = 4.94, 95% CI 2.86-7.03) and opioid treatment days (β = 4.86, 95% CI 2.61-6.75), and more adjunctive medication treatment (aOR = 2.57, 95% CI 1.49-4.42). Gabapentin was associated with longer LOS (β = 2.79, 95% CI 0.54-5.03), more NAS medication treatment (aOR = 2.96, 95% CI 1.18-7.42) including more adjunctive medications (aOR = 1.92, 95% CI 1.05-3.53).

CONCLUSION

For infants of mothers with OUD who are also on concurrent psychiatric medications, polypharmacy was associated with worse NAS severity. When medically indicated, limiting use of multiple psychiatric medications, particularly benzodiazepines and gabapentin, during pregnancy should be considered to improve NAS outcomes.

Health librarians: developing professional competence through a 'legitimate peripheral participation' model

Use of methadone in a highly tolerant patient receiving parenteral hydromorphone

A 59-year-old woman with metastatic breast cancer experienced a poor response to increasing doses of hydromorphone, possibly related to the neuropathic nature of her pain. Ultimately, the cost of this treatment was more than $1000 per day. Administration of methadone, initially as an adjuvant and eventually as the sole analgesic, at a much smaller dose than expected resulted in very satisfactory analgesia, without the development of serious side effects. In addition, the cost of treatment decreased to less than $25 per day. This case illustrates the rationale and advantages for the use of methadone. Intraindividual variability in the response to various opioids is a factor to be considered when selecting analgesics. Methadone is a useful second-line or third-line opioid for the patient who is highly tolerant to other opioids, as it may demonstrate incomplete cross-tolerance with other agonist opioids. Switching of the opioid to methadone may be a worthwhile option to consider in managing patients who are highly tolerant to other opioids.
