Life stress influences the relationship between sex hormone fluctuation and affective symptoms in peripubertal female adolescents

Female adolescents have a greatly increased risk of depression starting at puberty, which continues throughout the reproductive lifespan. Sex hormone fluctuation has been highlighted as a key proximal precipitating factor in the development of mood disorders tied to reproductive events; however, hormone-induced affective state change is poorly understood in the pubertal transition. The present study investigated the impact of recent stressful life events on the relationship between sex hormone change and affective symptoms in peripubertal female participants. Thirty-five peripubertal participants (ages 11-14, premenarchal, or within 1 year of menarche) completed an assessment of stressful life events, and provided weekly salivary hormone collections [estrone, testosterone, dehydroepiandrosterone (DHEA)] and mood assessments for 8 weeks. Linear mixed models tested whether stressful life events provided a context in which within-person changes in hormones predicted weekly affective symptoms. Results indicated that exposure to stressful life events proximal to the pubertal transition influenced the directional effects of hormone change on affective symptoms. Specifically, greater affective symptoms were associated with increases in hormones in a high stress context and decreases in hormones in a low stress context. These findings provide support for stress-related hormone sensitivity as a diathesis for precipitating affective symptoms in the presence of pronounced peripubertal hormone flux.

Analyzing the atypical - Methods for studying the menstrual cycle in adolescents

BACKGROUND

The female pubertal transition is characterized by a rapidly changing hormone milieu, which is heavily influenced by the first menstrual cycle - menarche. The first year following menarche is associated with menstrual cycles that are irregular and anovulatory. Peripuberty also marks the beginning of a female-biased risk for suicidality and depression, suggesting some influence by the menstrual cycle and ovarian hormone fluctuations. However, there are limited methods and guidelines for studying the menstrual cycle and related affective symptoms in this developmental window. Thus, this study's objective was to identify the most accurate methods for detecting ovulation in irregular cycles (Part 1) and develop guidelines based on these methods for determining menstrual cycle phases. These methods were applied to investigate hormones and affective symptoms based on cycle phase and ovulation status in a sample of peripubertal females (Part 2).

METHODS

Thirty-two peripubertal females (ages 11-14) provided daily urine samples of estrogen (E1G) and progesterone (PdG) metabolites and luteinizing hormone (LH), and ratings of affective symptoms for one menstrual cycle. Ten literature-derived methods for determining the presence of an LH-peak or PdG rise were compared, focusing on their feasibility for psychological research.

RESULTS

Methods by Sun et al. (2019) and Park et al. (2007) most accurately detected PdG rises and LH peaks in this sample, identifying 40.6% of cycles as ovulatory. As expected, ovulatory participants showed greater LH in the periovulatory phase (p = .001), greater PdG in the mid-luteal phase (p < .0001), and greater E1G in the periovulatory phase (p = .001) compared with anovulatory participants. Exemplary methods to compare psychological symptoms between both groups are provided.

CONCLUSIONS

Recommendations and guidelines for studying the menstrual cycle in irregular cycling adolescents are offered. Novel methods for ovulation detection identified phase-specific hormonal patterns in anovulatory and ovulatory adolescent cycles.

Biobehavioral mechanisms underlying testosterone and mood relationships in peripubertal female adolescents

The pubertal transition is characterized by pronounced sex hormone fluctuation, refinement of affective neural circuitry, and an increased risk of depression in female adolescents. Sex hormones, including testosterone, exert modulatory effects on frontal-limbic brain networks and are associated with emotion dysregulation and depressive symptoms. Weekly changes in hormones predict affective symptoms in peripubertal female adolescents, particularly in the context of stress; however, the biobehavioral mechanisms underlying hormone change and mood relationships during the pubertal transition have yet to be determined and was the objective of the present study. Forty-three peripubertal female adolescents (ages 11-14) collected 8-weekly salivary hormone (estrone, testosterone) samples and mood assessments to evaluate hormone-mood relationships, followed by a biobehavioral testing session with psychosocial stress and EEG. Within-person correlations between weekly hormone changes and corresponding mood were performed to determine individual differences in mood sensitivity to weekly hormone change. Increased frontal theta activity indexing emotion reactivity, reduced cortisol reactivity, and reduced vagal efficiency predicted the strength of the relationship between testosterone and mood. Further, testosterone-sensitivity strength was associated with the enhancement of negative affect following stress testing. Results identify divergent frontal theta and stress responses as potential biobehavioral mechanisms underlying mood sensitivity to peripubertal testosterone fluctuation.

Methods for characterizing ovarian and adrenal hormone variability and mood relationships in peripubertal females

Peripubertal females are at elevated risk for developing affective illness compared to males, yet biological mechanisms underlying this sex disparity are poorly understood. Female risk for depression remains elevated across a woman's reproductive lifespan, implicating reproductive hormones. A sensitivity to normal hormone variability during reproductive transition events (e.g., perimenopause) precipitates affective disturbances in susceptible women; however, the extent of hormone variability during the female pubertal transition and whether vulnerability to peripubertal hormone flux impacts affective state change in peripubertal females has not been studied. 52 healthy peripubertal females (ages 11-14) provided 8 weekly salivary samples and mood ratings. 10 salivary ovarian and adrenal hormones (e.g., estrone, testosterone, dehydroepiandrosterone (DHEA)) were analyzed weekly for 8 weeks using an ultrasensitive assay to characterize the female peripubertal hormone environment and its association with affective state. Hormone variability indices, including standard deviation, mean squared and absolute successive differences of the 8 weekly measurements were analyzed by menarche status. Within-person partial correlations were computed to determine the strength of the relationship between weekly change in hormone level and corresponding mood rating for each participant. As expected, results indicated that hormone variability was greater for post- relative to pre-menarchal females and with advancing pubertal development, yet pregnenolone-sulfate and aldosterone did not differ by menarche status. Mood sensitivity to changes in estrone was exhibited by 57% of participants, whereas 37% were sensitive to testosterone and 6% were sensitive to DHEA changes. The present results offer novel evidence that a substantial proportion of peripubertal females appear to be mood sensitive to hormone changes and may inform future investigations on the biological mechanisms underlying hormone-induced affect dysregulation in peripubertal females.

HPA axis activity across the menstrual cycle - a systematic review and meta-analysis of longitudinal studies

Differential HPA axis function has been proposed to underlie sex-differences in mental disorders; however, the impact of fluctuating sex hormones across the menstrual cycle on HPA axis activity is still unclear. This meta-analysis investigated basal cortisol concentrations as a marker for HPA axis activity across the menstrual cycle. Through a systematic literature search of five databases, 121 longitudinal studies were included, summarizing data of 2641 healthy, cycling participants between the ages of 18 and 45. The meta-analysis showed higher cortisol concentrations in the follicular vs. luteal phase (d_SMC = 0.12, p =.004, [0.04 - 0.20]). Comparisons between more precise cycle phases were mostly insignificant, aside from higher concentrations in the menstrual vs. premenstrual phase (d_SMC = 0.17, [0.02 - 0.33], p =.03). In all included studies, nine samples used established cortisol parameters to indicate HPA axis function, specifically diurnal profiles (k = 4) and the cortisol awakening response (CAR) (k = 5). Therefore, the meta-analysis highlights the need for more rigorous investigation of HPA axis activity and menstrual cycle phase.

O-018 Sperm count is increased by diet-induced weight loss and maintained by exercise or GLP-1 analogue treatment: a randomised controlled trial

Study question

Does diet-induced weight loss improve semen parameters, and are these possible improvements maintained with sustained weight loss?

Summary answer

An 8-week low-calorie diet-induced weight loss was associated with improved sperm count, which was maintained after one year in men who maintained weight loss.

What is known already

Obesity is associated with impaired semen parameters. Weight loss improves metabolic health in obesity, but there is a lack of knowledge on the acute and long-term effects of weight loss on semen parameters.

Study design, size, duration

This is a substudy of men with obesity enrolled in a randomised, controlled, double-blinded trial (the S-LITE trial). The trial was conducted between August 2016 and November 2019. A total of 56 men was included in the study and assigned to an initial 8-week low-calorie diet (800 kcal/day) followed by randomisation to 52 weeks of either: placebo, exercise training, and placebo (exercise), the GLP-1 analogue liraglutide (liraglutide) or liraglutide in combination with exercise training (combination).

Participants/materials, setting, methods

Inclusion criteria were men who delivered semen samples, 18 to 65 years of age and a body mass index between 32 to 43 kg/m2, but otherwise healthy. The study was carried out at Hvidovre Hospital and at the University of Copenhagen, and the participants were from the Greater Copenhagen Area. We assessed semen parameters, anthropometrics and collected blood samples before (T0) and after the 8-week low-calorie dietary intervention (T1) and after 52 weeks (T2).

Main results and the role of chance

The men lost on average 16.5 kg (95% CI: 15.2-17.8) bodyweight during the low-calorie diet, which increased sperm concentration 1.49 fold (95% CI: 1.18-1.88, P&lt;0.01) and sperm count 1.41 fold (95% CI: 1.07-1.87, P&lt;0.01). These improvements were maintained for 52 weeks in men who maintained the weight loss but not in men who regained weight. Semen volume, sperm motility and motile sperm count did not change.

Limitations, reasons for caution

The S-LITE trial was a randomised controlled trial of weight loss maintenance. Analysis of semen was preregistered to explore the effects of weight loss and weight loss maintenance on semen parameters. Due to the small sample size, definite inferences cannot be made.

Wider implications of the findings

This study shows that sperm concentration and sperm count were improved after a diet-induced weight loss in men with obesity. Our findings indicate that both liraglutide and exercise as weight maintenance strategies may be used to maintain the improvements in sperm concentration and count.

P-038 Comparison of three methods of semen analysis: A novel at-home sperm test kit, a computer-assisted assessment and an embryologist

Study question

How does computer-assisted semen analysis (CASA) (Lenshooke, LOGIXX) and at-home sperm testing (ExSeed) compare with manual methodology assessment of male fertility based on WHO criteria (5thEdition); a three-method comparison study.

Summary answer

All methods showed good agreement for concentration and limited agreement for motility highlighting the need for further development of alternatives to manual assessment.

What is known already

Several studies have shown good correlation between CASA systems and laboratory-based manual semen analysis, but only a few have carried out a three-way comparison study. One of which showed positive correlation with motility and concentration between a smartphone-based semen analysis and laboratory-based CASA system and positive correlation between concentration and motility between the smartphone-based CASA system and microscopic-based results. The at-home sperm test kit may play a role in motivating infertile males to visit clinics for early diagnosis and also reducing the need for multiple visits to the fertility clinic for repeat semen analyses.

Study design, size, duration

Fifty patients (between 29 and 56 years) attending a fertility clinic were included in the study between September 2021 to December 2021. Semen samples were split into 3 aliquots and evaluated using manual semen assessment (MSA) according to the WHO 5th Edition (2010) guidelines, the ExSeed Home Sperm Test (HST) and the LensHooke® X1 PRO Semen Quality Analyzer (CASA).

Participants/materials, setting, methods

The semen samples were collected from fifty participants at CARE Fertility Tunbridge Wells. The samples were placed in an incubator at 37°C for 30 minutes to liquefy. After liquefaction, sperm concentration, total motility, total motile sperm count (TMSC) and normal morphology were evaluated. Spearman’s Rank correlations (&gt;0.7) and Chi-squared tests were used and the p-value &lt; 0.05 was considered as statistically significant.

Main results and the role of chance

All variables were highly significantly (p &lt; 0.0002) positively correlated between all 3 methods.

The greatest correlations were obtained for sperm concentration (CASA/HST: r = 0.826; MSA/HST: r = 0.870; MSA/CASA: r = 0.871) and TMSC (MSA/CASA: p = 0.792; CASA/HST: r = 0.800; MSA/HST: r = 0.854). Correlations for motility were markedly lower (MSA/HST: r = 0.611; CASA/HST: r = 0.717; MSA/LCASA: r = 0.750). The lowest correlation was found for morphology (MSA/CASA: r = 0.500). The HST device does not determine morphology.

As compared to MSA, using the HST device agreement for normal or low sperm concentration (≥15 × 106/mL or &lt; 15 × 106/mL respectively) was identified in 84.3% of the cases, whereas 94.0% with CASA. The agreement between CASA and HST was 82.0%. For total motility ≥ or &lt; 40%, the agreements were 68.0% (CASA/HST), 56.9% (MSA/HST) and 82.0% (MSA/CASA), respectively.

For the identification of patients with normal morphology &gt;4%, the agreement between MSA and CASA was 30%.

Limitations, reasons for caution

The small sample size was 50 cases. The home testing device does not assess morphology. Furthermore, it is difficult to ascertain whether a consumer would carry out the analysis with this device with the same accuracy as an embryologist.

Wider implications of the findings

The need for repeated semen analyses, the effect of the COVID-19 pandemic and the discomfort some patients feel in a clinical setting, necessitate the need for evaluation of novel semen analysis approaches. These emerging technologies have potential to be more patient friendly, convenient and efficient than standard semen assessment methods.

Impact of Mentoring on Academic Career Success for Women in Medicine: A Systematic Review

PURPOSE

Research has shown that barriers to career success in academic medicine disproportionately affect women. These barriers include inadequate mentoring, which may perpetuate the underrepresentation of women in senior leadership positions. The purpose of this review was to summarize the qualitative and quantitative evidence of the impact of mentoring on women's career outcomes and to inform future interventions to support the promotion and retention of women in academic medicine.

METHOD

The authors conducted a systematic review of original research published in English-language, peer-reviewed journals through March 20, 2020. Search terms related to mentorship, women, and academic medicine. The authors searched MEDLINE, Embase, Scopus, Current Contents Connect via Web of Science, Cochrane Library, and PsycINFO. They excluded studies not specifically addressing women and those without gender-stratified outcomes. They extracted and analyzed the following data: study design, population, sample size, response rate, participant age, percentage of women, mentoring prevalence, and outcomes.

RESULTS

Of 2,439 citations identified, 91 studies met the inclusion criteria, including 65 quantitative and 26 qualitative studies. Mentoring was associated with objective and subjective measures of career success. Women perceived mentorship to be more valuable to their career development yet were more likely to report having no mentor. Additionally, women were more likely to report lower levels of research productivity, less career satisfaction, and greater barriers to promotion. Qualitative results indicated that women had less access to informal mentoring and family responsibilities had a greater effect on their career outcomes. Professional networking, female mentors, and relational aspects of mentoring were common themes.

CONCLUSIONS

This review examined gender disparities in mentoring and the impact on research productivity, promotion success, and career satisfaction for women in academic medicine. Institution-supported mentoring programs are needed to facilitate identification of appropriate mentors and promotion of a more equitable academic career environment for women.

Factors associated with residents’ responsive behaviours towards staff in long-term care homes: A systematic review

Background and Objectives

When staff experience responsive behaviors from residents, this can lead to decreased quality of work-life and lower quality of care in long-term care homes. We synthesised research on factors associated with resident responsive behaviours directed towards care staff and characteristics of interventions to reduce the behaviours.

Research Design and Methods

We conducted a mixed-methods systematic review with quantitative and qualitative research. We searched 12 bibliographic databases and “grey” literature, using two keywords (long-term care, responsive behaviours) and their synonyms. Pairs of reviewers independently completed screening, data extraction, and risk of bias assessment. We developed a coding scheme using the ecological model as an organising structure and prepared narrative summaries for each factor.

Results

From 86 included studies (57 quantitative, 28 qualitative, 1 mixed methods), multiple factors emerged, such as staff training background (individual level); staff approaches to care (interpersonal level); leadership and staffing resources (institutional level); and racism and patriarchy (societal level). Quantitative and qualitative results each provided key insights, such as qualitative results pertaining to leadership responses to reports of behaviours, and quantitative findings on the impact of staff approaches to care on behaviours. Effects of interventions (n=14) to reduce the behaviours were inconclusive.

Discussion and Implications

We identified the need for enhanced understanding of the interrelationships among factors associated with resident responsive behaviours towards staff and processes leading to the behaviours. To address these gaps and to inform theory-based effective interventions for preventing or mitigating responsive behaviours, we suggest intervention studies with systematic process evaluations.

Effects of Mindfulness-Based Stress Reduction on Experimental Pain Sensitivity and Cortisol Responses in Women With Early Life Abuse: A Randomized Controlled Trial

OBJECTIVE

Early life abuse (ELAb) initiates pathophysiological cascades resulting in long-term maladaptive stress responsivity, hyperalgesia, and an increased risk of psychopathology. Mindfulness-based stress reduction (MBSR) is effective in modifying psychological and somatic symptoms; thus, we predicted that MBSR would be particularly efficacious for women with ELAb.

METHOD

Medically healthy women (mean age = 31 years) with or without a history of early (≤13 years) physical or sexual abuse provided self-report measures and were tested in the laboratory before and after randomization to standard MBSR (n = 52) or social support (SSG) (n = 60) for 8 weeks. The laboratory procedure involved pain testing using the cold pressor and temporal summation of heat pain (indexing central sensitization) procedures, and exposure to the Trier Social Stress Test. Plasma cortisol in response to the experimental protocol was assessed as area under the curve (AUC).

RESULTS

The interventions differentially impacted pain sensitivity and cortisol AUC for women with ELAb, as MBSR increased the temporal summation of heat pain intensity ratings (p = .024) and reduced cortisol AUC (p = .004). For women without ELAb, MBSR decreased cold pressor tolerance (p = .045) and decreased the temporal summation of heat pain intensity ratings relative to SSG (p = .024). Both MBSR and SSG improved depression symptoms and emotion regulation abilities (p values < .001); however, MBSR was associated with greater benefits in describing emotions (p = .008) and impulse control (p = .017) for women with ELAb.

CONCLUSIONS

Women with ELAb benefited from MBSR-specific improvements in central sensitization, mindfulness skills, and emotion regulation abilities. This is the first study to examine the efficacy of MBSR in modifying affective and somatic symptoms based on ELAb status and provides evidence for considering ELAb in tailoring treatment approaches.Trial Registration: ClinicalTrials.gov Identifier: NCT01995916; https://clinicaltrials.gov/ct2/show/NCT01995916.

Simplified sperm testing devices: a possible tool to overcome lack of accessibility and inconsistency in male factor infertility diagnosis. An opportunity for low- and middle- income countries

Background

Manual semen assessment (MSA) is a key component in a male’s fertility assessment. Clinicians rely on it to make diagnostic and treatment decisions. When performed manually, this routine laboratory test is prone to variability due to human intervention which can lead to misdiagnosis and consequently over- or under- treatment. For standardisation, continuous training, quality control (QC) programs and pricy Computer-Assisted Sperm Analysis (CASA) systems have been proposed, yet, without resolving intra- and inter-laboratory variability. In response, promising simplified sperm testing devices, able to provide cost-effective point-of-care male infertility diagnosis are prospected as a plausible solution to resolve variability and increase access to sperm testing.

Materials and methods

A throughout literature research for semen testing, sperm analysis, smart-phone assisted semen analysis, ‘at-home’ semen testing, male infertility, infertility in developing countries, infertility in low- and middle-income countries (LMIC) and quantitative sperm analysis was performed. A total of 14 articles, specific to ‘at-home’ simplified sperm assessment, were included to treat the core subject.

Results

Continuous training and consistent QC, are sine qua none conditions to achieve accurate and comparable MSA. Compliance does not rule-out variability, nevertheless. Emerging simplified sperm assessment devices are an actual alternative to resolve the lack of standardisation and accessibility to sperm analysis. YO ® , SEEM ® , and ExSeed ® are commercially available, user-friendly smartphone-based devices which can accurately measure volume, sperm concentration (millions/ml) and total motile sperm count. More broadly, by cost-effectiveness, availability, accuracy and convenient application, these devices could effectively select patients for first-line artificial reproduction treatments such as intrauterine insemination.

Conclusions

Accuracy and cost-effectiveness make smart-phone based sperm testing devices a practical and realistic solution to overcome variability in MSA. Importantly, these tools represent an actual opportunity to standardise and improve male subfertility diagnosis and treatment, especially in LMIC. However, before clinical application is possible, guidelines, further testing with special attention on accuracy in washed sperm, availability, cost-benefit and reliability are required.

Examining fidelity in the INFORM trial: a complex team-based behavioral intervention

Background

Fidelity in complex behavioral interventions is underexplored. This study examines the fidelity of the INFORM trial and explores the relationship between fidelity, study arm, and the trial’s primary outcome—care aide involvement in formal team communications about resident care.

Methods

A concurrent process evaluation of implementation fidelity was conducted in 33 nursing homes in Western Canada (Alberta and British Columbia). Study participants were from 106 clinical care units clustered in 33 nursing homes randomized to the Basic and Enhanced-Assisted Feedback arms of the INFORM trial.

Results

Fidelity of the INFORM intervention was moderate to high, with fidelity delivery and receipt higher than fidelity enactment for both study arms. Higher enactment teams experienced a significantly larger improvement in formal team communications between baseline and follow-up than lower enactment teams (F(1, 70) = 4.27, p = .042).

Conclusions

Overall fidelity enactment was associated with improvements in formal team communications, but the study arm was not. This suggests that the intensity with which an intervention is offered and delivered may be less important than the intensity with which intervention participants enact the core components of an intervention. Greater attention to fidelity assessment and publication of fidelity results through studies such as this one is critical to improving the utility of published trials.

Prevalence of type 2 diabetes and associated risk factors among Saharawi refugees in Algeria

Background

The Saharawi refugees have been living in refugee camps in the Algerian desert since 1975 and are dependent on food aid. A double burden of malnutrition by the coexistence of undernutrition among children and overweight and obesity among adults has been observed in the Saharawi refugee camps. Limited knowledge about the prevalence of type 2 diabetes (T2D) and associated risk factors exists in this population. The aim of this study was, therefore, to address this gap in the literature.

Methods

A cross-sectional survey was carried out in five Saharawi refugee camps in Algeria in 2014. A total of 180 women and 175 men were included. HbA1c was used to assess the prevalence of T2D and prediabetes. The Finnish Diabetes Risk Score (FINDRISC) was used to estimate the risk of developing T2D. Multiple logistic regressions were performed to assess risk factors associated with T2D and prediabetes.

Results

Median (min, max) HbA1c among the Saharawi refugees was 35 (4, 135) mmol/mol. The prevalence of T2D and prediabetes was 7% and 10%, respectively. The prevalence of overweight and obesity combined was 45%, and higher in women than in men. According to FINDRISC, 9% of participants had high risk of developing diabetes and 10% had moderate risk. In adjusted models, significant predictors for T2D were age, waist circumference and having a first-degree relative with T2D. Significant predictors for prediabetes were age, body mass index (BMI), waist circumference and a history of high blood glucose.

Conclusions

We found moderate prevalence of diabetes and prediabetes and a relatively high prevalence of overweight and obesity among the Saharawi refugees, especially the women. Given the fragility of the Saharawi health care system, screening for diabetes should be conducted in a cost-effective manner and high-risk individuals should receive advice about lifestyle changes (e.g. diet and physical activity).

Key messages

We found moderate prevalence of diabetes and pre-diabetes among the Saharawi refugees, and a high proportion were classified as overweight or obese. In light of this, the rates of T2D are likely to increase in the near future. The Saharawi health authorities should pay attention to the increased risk of diabetes in this vulnerable population.

Early Mortality after Radical Radiotherapy in Head and Neck Cancer - A Nationwide Analysis from the Danish Head and Neck Cancer Group (DAHANCA) Database

AIMS

Curative-intent radiotherapy (RT) or chemoradiation (CRT) of squamous cell carcinoma of the head and neck (HNSCC) produces high survival rates, but is associated with substantial toxicity. However, there are no commonly accepted quality metrics for early mortality in radiation oncology. To assess the applicability of early mortality as a clinical quality indicator, this study investigated the temporal distribution, risk factors and trends of 90- and 180-day overall and non-cancer mortality in a nationwide cohort of HNSCC patients treated with RT/CRT.

MATERIALS AND METHODS

Information on all HNSCC patients treated with curative-intent RT/CRT in Denmark between 2000 and 2017 was obtained from the national Danish Head and Neck Cancer Group clinical database. Deaths in patients with residual or recurrent disease after RT/CRT were classified as cancer-related. Possible risk factors were investigated using logistic regression analysis.

RESULTS

Data from 11 419 patients were extracted. In total, 90- and 180-day mortality risks were 3.1% and 7.1%, respectively. There was a uniform temporal distribution of 180-day mortality. In multivariable analysis, increasing age, stage, performance status, earlier treatment year and hypopharyngeal cancer were significantly associated with an increased risk (P < 0.05). Risk factor estimates were comparable for 90- versus 180-day mortality as well as for overall versus non-cancer mortality. Between 2000 and 2017 there was a significant decrease in 180-day mortality, which was driven by a reduction in cancer-related events.

CONCLUSION

The distribution of 180-day overall and non-cancer mortality did not indicate a well-defined early high-risk period. Moreover, risk factor estimates were highly similar across risk periods and groups. Taken together, our findings question the applicability of early mortality as a standard metric for treatment-associated toxicity.

Effectiveness of Briefer Coping-Focused Psychotherapy for Common Mental Complaints on Work-Participation and Mental Health: A Pragmatic Randomized Trial with 2-Year Follow-Up

Purpose The aim of this study was to assess short and long-term effectiveness of brief coping-focused psychotherapy (Brief-PsT) compared with short-term psychotherapy (Short-PsT) on work-participation (WP) and mental health. Both treatments were preceded by group education. Methods All participants were on, or at risk of, sick leave due to common mental complaints. Patients were selected for inclusion in this study based on levels of self-reported symptoms ('some' or 'seriously affected') of anxiety and depression. They were randomized to Brief-PsT (n = 141) or Short-PsT with a more extended focus (n = 143). Primary outcome was the transition of WP-state from baseline to 3 months follow-up. In addition, WP at 12 and 24 months follow-up were assessed. The secondary outcome, clinical recovery rate (CR-rate) was obtained from the Beck Depression and Beck Anxiety Inventories, at 2-year follow-up. In addition, self-reported mental health symptom severity, self-efficacy, subjective health complaints and life satisfaction were assessed. Results At 3 months follow-up, the increase in WP was significantly greater in Brief-PsT than in Short-PsT (p = 0.039). At 3 months, 60% in Brief-PsT and 51% in Short-PsT was at work, partial or full. Thereafter, these differences diminished, 84% and 80% were at work at 2-year follow up. The 2-year follow-up of the secondary outcome measurements was completed by 53% in Brief-PsT and 57% in Short PsT. CR-rate was significantly greater in Brief-PsT compared with the Short-PsT (69% vs. 51%, p = 0.024). Furthermore, there was a greater reduction in the number of subjective health complaints in Brief-PsT (4.0 vs. 1.9 p = 0.012). All other measurements favoured Brief-PsT as well, but did not reach statistical significance. Conclusions Brief coping-focused psychotherapy added to group education for persons with depression or anxiety complaints seemed more effective in enhancing early work participation compared with additional short-term psychotherapy of standard duration with more extended focus. Clinical recovery rate and decline of comorbid subjective health complaints at 2-year follow-up were also in favour of the brief coping-focused program.

Effect of an Interactive Website to Engage Patients in Advance Care Planning in Outpatient Settings

PURPOSE

Online programs may help to engage patients in advance care planning in outpatient settings. We sought to implement an online advance care planning program, PREPARE (Prepare for Your Care; http://www.prepareforyourcare.org), at home and evaluate the changes in advance care planning engagement among patients attending outpatient clinics.

METHODS

We undertook a prospective before-and-after study in 15 primary care clinics and 2 outpatient cancer centers in Canada. Patients were aged 50 years or older (primary care) or 18 years or older (cancer care) and free of cognitive impairment. They used the PREPARE website over 6 weeks, with reminders sent at 2 or 4 weeks. We used the 55-item Advance Care Planning Engagement Survey, which measures behavior change processes (knowledge, contemplation, self-efficacy, readiness) on 5-point scales and actions relating to substitute decision makers, quality of life, flexibility for the decision maker, and asking doctors questions on an overall scale from 0 to 21; higher scores indicate greater engagement.

RESULTS

In total, 315 patients were screened and 172 enrolled, of whom 75% completed the study (mean age = 65.6 years, 51% female, 35% had cancer). The mean behavior change process score was 2.9 (SD 0.8) at baseline and 3.5 (SD 0.8) at follow-up (mean change = 0.6; 95% CI, 0.49-0.73); the mean action measure score was 4.0 (SD 4.9) at baseline and 5.2 (SD 5.4) at follow-up (mean change = 1.2; 95% CI, 0.54-1.77). The effect size was moderate (0.75) for the former and small (0.23) for the latter. Findings were similar in both primary care and cancer care populations.

CONCLUSIONS

Implementation of the online PREPARE program in primary care and cancer care clinics increased advance care planning engagement among patients.

The information-seeking patterns of care aides who work in nursing homes

AIM

To explore the information-seeking patterns of care aides who work in nursing homes.

BACKGROUND

Under the direction and supervision of nursing professionals, care aides provide the majority of direct care to nursing home residents. Understanding how, why, when and where they seek information to perform their duties is important for managers, policymakers and stakeholders.

METHOD

Semi-structured interviews with eight care aides employed in three Canadian nursing homes were analysed using the Braun and Clarke method of thematic analysis.

RESULTS

Five prominent information-seeking patterns emerged as themes.

CONCLUSIONS

Care aides were motivated to seek information for personal and job-based reasons that included wanting to avoid mistakes and preparing physically, mentally and emotionally for the work ahead. They described depending on a social hierarchy of verbal information and using personal time (before/after work) to seek the information they needed. Due to time constraints, they relied on established patterns, accessed online information once a day at most and preferred paper-based sources.

IMPLICATIONS FOR NURSING MANAGEMENT

Programs to enhance care aide communication skills to include the importance of information-seeking are warranted. Time for formal information-seeking during working hours should be provided and encouraged. When care aides initiate information-seeking to improve care this should be recognized and respected by others on the team.

Risk profiling based on p16 and HPV DNA more accurately predicts location of disease relapse in patients with oropharyngeal squamous cell carcinoma

BACKGROUND

In the era of precision medicine and HPV-related oropharyngeal squamous cell carcinoma (OPSCC), it is relevant to assess the risk of not only survival, but also the risk of local, regional, or distant treatment failure. The UICC 8th edition uses the surrogate marker p16 to stratify for HPV association but discordance between p16 status and HPV association has been shown. The purpose of this study was to develop a prognostic model to predict the risk of local, regional, and distant metastases and non-cancer-related death for patients with OPSCC, test the prognostic relevance of adding HPV DNA and p16 status, and validate the findings in an independent external dataset.

PATIENTS AND METHODS

Consecutive patients diagnosed with OPSCC and treated with curative radiotherapy with or without cisplatin in eastern Denmark from 2000 to 2014 were included. Characteristics included age, gender, TNM stage, smoking habits, performance status, and HPV status assessed with p16 and HPV DNA. The information was used to develop a prognostic model for first site of failure with four competing events: recurrence in T-, N-, and M-site, and death with no evidence of disease.

RESULTS

Overall 1243 patients were eligible for the analysis. A prognostic model with the four events was developed and externally validated in an independent dataset with a heterogeneously treated patient population from another institution. The individual prognostication from the competing risk analysis is displayed in a user friendly online tool (https://rasmussen.shinyapps.io/OPSCCmodelHPV_p16/). Replacing p16 status with the combined variable HPV/p16 status influenced the HR and patients with HPV-/p16+ had significantly higher HR of M-site recurrence than HPV+/p16+ with a HR = 2.56; CI [1.30; 5.02]; P = 0.006 (P = 0.013 in the validation cohort).

CONCLUSION

Patients with HPV-/p16+ have significantly higher risk of M-site recurrence and could potentially be relevant candidates for clinical trials testing systemic treatments in combination with conventional treatments.

Best practices for teaching pharmacology to undergraduate nursing students: A systematic review of the literature

OBJECTIVE

In this systematic review we describe best practices for teaching pharmacology to undergraduate baccalaureate nursing students based on the available evidence. Numerous teaching strategies employed in undergraduate pharmacology courses for nursing students have been summarized and compared for their impact on pharmacology knowledge retention, application of pharmacology theory to practice, and student satisfaction. Future directions for research are discussed.

DESIGN

The review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews and meta-analyses.

DATA SOURCES

The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Academic Search Complete, Education Resources Information Center (ERIC), and Education Source and Health Reference Centre Academic were searched using key search terms and phrases. Twenty studies, conducted between 2001 and 2017, met the inclusion criteria.

METHOD

Quality assessment was made in accordance with two appraisal tools: Kirkpatrick's framework and the Medical Education Research Quality Instrument (MERSQI) for quantitative studies.

RESULTS

Online, simulation, and integrated methods of teaching pharmacology were most beneficial for pharmacology knowledge acquisition and student satisfaction. Traditional lecture, problem-based learning, and a flipped classroom were least effective strategies for teaching pharmacology to undergraduate students.

CONCLUSIONS

This systematic review will contribute to the body of knowledge used by nurse educators who teach in undergraduate nursing programs, may be particularly useful for undergraduate nursing program directors/administrators who are considering undergoing curricular changes, and may be a conduit for future researchers who wish to design studies aimed at improving teaching and learning within undergraduate nursing education.

Using landscape scenarios to improve local nitrogen management and planning

Scenario-building is a widely used tool to initiate discussions on future land uses. In scenarios possible futures can be explored and peoples' ideas as well as societal trends can be visualized by the use of maps, pictures and figures. With focus on agricultural nitrogen management, and point of departure in the farmers' decisions-regarding fertilizer inputs, crop rotations, land use, and drainage, landscape scenarios are formulated based on local ideas for future nitrogen management and general prospects for local development. The key research question addressed in this paper is how landscape scenarios can guide farmers to improve nitrogen management in smaller catchments dominated by farming. Participatory modelling was used to develop landscape scenarios, depicting the change of nitrogen emission as a result of changes in landscape management and agricultural practices. In the development of the scenarios we used an ArcMap based tool combining statistical data, experimental knowledge, nitrate leaching modelling and input from local stakeholders on biophysical as well as land use and farm management issues. The scenarios presented are the result of a collaborative planning experiment within the frames of the dNmark research alliance on nitrogen. Three different types of scenarios are presented and discussed and their effects in terms of N reduction are estimated. The three scenarios were called: River valley set-aside, constructed wetlands, and land zonation. All the modelled scenarios are estimated to have a positive effect i.e. a reduction of the level of N leached to the root zone. Based on the experience gathered in the project, the feasibility of using scenarios for future environmental planning in the agricultural landscapes is discussed. Further, this is related to the current discussion in Denmark on geographically targeted nitrogen regulation. It is concluded that the co-creative approach to formulation of scenarios can be an effective way of increasing the knowledge and ownership of possible future solutions, however the cost associated with this planning approach is likely to substantially higher that more traditional planning approaches. Consequently, the estimated transactions costs should be weighed against the expected benefits in terms of more successful implementation.

Outcomes of collaborative and interdisciplinary palliative education for health care assistants: A qualitative metasummary

AIM

To explore collaborative and interdisciplinary palliative educational strategies and corresponding outcomes for health care assistants.

BACKGROUND

Health care assistants are frontline staff who provide almost all hands-on care to seniors. Health care managers are responsible to provide ongoing support and a working environment conducive to health care assistants' abilities to provide quality, safe, evidence-based care.

EVALUATION

A Qualitative metasummary of collaborative and interdisciplinary teaching strategies was conducted following guidelines developed by Sandelowski et al. ().

KEY ISSUES

The gold standard of palliative care is interdisciplinary delivery of care, yet education is often monodisciplinary. Furthermore, evaluation of interdisciplinary continuing education is most often subjective via self-report questionnaires.

CONCLUSIONS

Findings from 16 articles representing 15 studies conducted between 2007 and 2017 were grouped thematically and summarized. Collaborative or interdisciplinary palliative interventions offer health care assistants opportunities to debrief, build their confidence, and critically reflect on the importance of psychosocial care for patients, family and colleagues.

IMPLICATIONS FOR NURSING MANAGEMENT

The metasummary provides six suggestions for managers who are considering implementing a collaborative palliative educational workshop and draws attention to the need to create contextual changes that support health care assistants to enact newly acquired knowledge and skills.

Acute stress modifies oscillatory indices of affective processing: Insight on the pathophysiology of schizophrenia spectrum disorders

OBJECTIVE

The current study evaluated the differential impact of acute psychosocial stress exposure on oscillatory correlates of affective processing in control participants and patients with schizophrenia spectrum disorders (SCZ) to elucidate the stress-mediated pathway to psychopathology.

METHODS

EEG was recorded while 21 control participants and 21 patients with SCZ performed emotional framing tasks (assessing a key aspect of emotion regulation (ER)) before and after a laboratory stress challenge (Trier Social Stress Test). EEG spectral perturbations evoked in response to neutral and aversive stimuli (presented with positive or negative contextual cues) were extracted in theta (4-8 Hz) and beta (12-30 Hz) frequencies.

RESULTS

Patients demonstrated aberrant theta and beta oscillatory activity, with impaired frontal theta-mediated framing and beta-derived motivated attention processes relative to controls. Following stress exposure, controls exhibited impaired frontal theta-mediated emotional framing, similar to the oscillatory profile observed in patients before stress.

CONCLUSIONS

The acute stress-induced oscillatory changes observed in controls were persistently present in patients, indicating an inefficiency of fronto-limbic adaptation to stress exposure.

SIGNIFICANCE

Results provide novel insight on the electrophysiological correlates of arousal and affect regulation, which are core homogeneous symptom dimensions shared across neuropsychiatric disorders, and shed light on putative mechanisms in the translation of stress into psychopathology.

"I will go if I don't have to talk": Nursing students' perceptions of reflective, debriefing discussions and intent to participate

BACKGROUND/OBJECTIVES

The ability to be a reflective practitioner is recognized by nursing regulatory bodies as a component of professional competence and becoming a reflective practitioner is an essential part of learning to become a nurse. In this multi-site study, we explored undergraduate nursing students' beliefs, capacities and intentions to participate in reflective, debriefing discussions facilitated by clinical instructors. At the same time, we tested the effectiveness of a period of rest and an intervention designed to refresh and inspire them.

DESIGN

A randomized crossover design.

SAMPLE

Our analyzed sample consisted of 106 students; 87.7% were female and 65.1% were less than 20 years old.

METHOD

This study was guided by the Theory of Planned Behaviour and consisted of five steps: instrument development, recruitment, random assignment to intervention, data collection at two time points using four tools, and data analysis. One hundred and forty-one first year nursing students used a learning management system to sign up to one of 15 potential clinical groups; maximum 10 students per group. Eight groups were randomly assigned to an intervention during post-clinical discussions; seven groups participated in the usual post-clinical discussions for the same length of time. After six weeks, the groups 'crossed-over' (switched).

RESULTS

Students had a negative attitude towards routine discussions that occur after clinical practice experiences which did not significantly improve despite a period of rest and an intervention. Most did not feel in control and felt social pressure to participate. Additional results revealed that most students arrived at reflective post-clinical discussions with an underlying intent not to talk. Intent to remain silent (not participate) did not significantly improve despite a period of rest and intervention.

CONCLUSIONS

The context and timing of the routine discussions may dramatically influence students' decision-making regarding intent to participate. Reflective processes require time and routine reflective debriefing discussions could be delayed until later in the week after students have had a chance to absorb and assimilate their experiences.

Failure to rescue as a nurse-sensitive indicator

PROBLEM

The aim of this concept analysis was to clarify failure to rescure as a nurse-sensitive indicator. Although the concept of failure to rescue as a nurse-sensitive outcome has appeared in the nursing literature for over a decade, conceptual clarity is needed to address its variable and ambiguous use in health care.

METHODS

Walker and Avant's eight-stage method of concept analysis was used to explore the concept of failure to rescue in nursing practice. Twenty-one papers were retrieved from Cumulative Index of Nursing and Allied Health Literature (CINAHL) and MEDLINE databases and selected for review and synthesis.

RESULTS

Failure to rescue as a nurse-sensitive indicator was found to be a "failing to rescue" process characterized by a cascade of events, including four key attributes: (1) errors of omission in care, (2) failure to recognize changes in patient condition, (3) failure to communicate changes, and (4) failures in clinical decision making.

CONCLUSIONS

Nurses have a pivotal role in "failing to rescue" through early recognition, escalation, and intervention of subtle changes signaling complications. Upstream strategies, such as the use of early warning sign indicators, structured communication, and teamwork, shift the discourse from failure to rescue, to processes in nursing practice of good catch events.

The intervention process in the European Fans in Training (EuroFIT) trial: a mixed method protocol for evaluation

BACKGROUND

EuroFIT is a gender-sensitised, health and lifestyle program targeting physical activity, sedentary time and dietary behaviours in men. The delivery of the program in football clubs, led by the clubs' community coaches, is designed to both attract and engage men in lifestyle change through an interest in football or loyalty to the club they support. The EuroFIT program will be evaluated in a multicentre pragmatic randomised controlled trial (RCT), for which ~1000 overweight men, aged 30-65 years, will be recruited in 15 top professional football clubs in the Netherlands, Norway, Portugal and the UK. The process evaluation is designed to investigate how implementation within the RCT is achieved in the various football clubs and countries and the processes through which EuroFIT affects outcomes.

METHODS

This mixed methods evaluation is guided by the Medical Research Council (MRC) guidance for conducting process evaluations of complex interventions. Data will be collected in the intervention arm of the EuroFIT trial through: participant questionnaires (n = 500); attendance sheets and coach logs (n = 360); observations of sessions (n = 30); coach questionnaires (n = 30); usage logs from a novel device for self-monitoring physical activity and non-sedentary behaviour (SitFIT); an app-based game to promote social support for physical activity outside program sessions (MatchFIT); interviews with coaches (n = 15); football club representatives (n = 15); and focus groups with participants (n = 30). Written standard operating procedures are used to ensure quality and consistency in data collection and analysis across the participating countries. Data will be analysed thematically within datasets and overall synthesis of findings will address the processes through which the program is implemented in various countries and clubs and through which it affects outcomes, with careful attention to the context of the football club.

DISCUSSION

The process evaluation will provide a comprehensive account of what was necessary to implement the EuroFIT program in professional football clubs within a trial setting and how outcomes were affected by the program. This will allow us to re-appraise the program's conceptual base, optimise the program for post-trial implementation and roll out, and offer suggestions for the development and implementation of future initiatives to promote health and wellbeing through professional sports clubs.

Metabolic health in patients with schizophrenia – CVD risk in a Norwegian outpatient population

The mortality of schizophrenia patients is approximately twice that of the general population and there is a 20% reduction in life expectancy in this patient group. Cardiovascular disease (CVD) is responsible for as much as 50% of the excess mortality associated with schizophrenia. One important source of the high CVD prevalence is the cluster of metabolic characteristics defining the metabolic syndrome (MetS: 3 or more of the following features: abdominal obesity, high blood pressure, elevated levels of triglycerides and fasting glucose and low levels of high-density lipoproteins). Patients with schizophrenia seem to be undertreated for these vascular risk factors relative to the general population. More knowledge is needed concerning broadened risk factors of cardiovascular disease in a representative sample of schizophrenia patients. We conducted preliminary cross sectional analyses in a sample of 64 consecutive outpatients with schizophrenia with a mean age of 37 years consisting of 59% men, who were enrolled in a treatment study. All used antipsychotics, and 71% were smokers. We found that (percentage of patients under treatment for the respective somatic condition in parenthesis) 82% were overweight, 49% had hypertonia (17%), 24% hyperglycemia (3%), 48% hypertriglyceridemia and 13% hyperlipidemia (10% triglycerid or cholesterol lowering medication). Forty percent had metabolic syndrome compared to 11% in the normal population (Norway, age corrected). Additionally, estimates of insulin resistance will be conducted. We found that the prevalence of MetS components was high in outpatient schizophrenia. A substantial discrepancy was found between metabolic ill health and medication treatment of such conditions.

Neutrophil Elastase and its Inhibitors in Human Gingival Crevicular Fluid during Experimental Gingivitis

The relative concentrations and absolute amounts of neutrophil elastase and its two inhibitors, α2-macroglobulin (α2-M) and alantitrypsin (α1-AT), were determined in gingival crevicular fluid (GCF) collected from six dental students who refrained from brushing the upper left or right quadrant during three weeks. Plaque and gingival indices and flow of GCF were measured before, during, and after the three weeks of no brushing. Functional elastase, representing the enzyme complexed with a2-M, was measured by use of a low-molecular-weight fluorogenic substrate. Elastolytic activity in GCF was also assayed by use of elastin as substrate. Antigenic elastase, representing the enzyme complexed with a 1-AT, as well as the inhibitors a2-M and al-AT were measured by ELISA. After three weeks of plaque accumulation, the concentrations of both functional and antigenic elastase increased by a factor of about 3, whereas the concentrations of the inhibitors increased in a much higher proportion. No free elastase could be detected in GCF, as evidenced by the Sephadex G-75 elution profile of GCF, by the negative results obtained when elastin was used as substrate, and by the demonstration that pure enzyme kept its activity against the low-molecular-weight substrate after being saturated by a2-M.

Risk factors for postoperative complications after total laryngectomy following radiotherapy or chemoradiation: a 10-year retrospective longitudinal study in Eastern Denmark

OBJECTIVES

To determine the rates of and risk factors for postoperative complications following total laryngectomy in patients treated with radiotherapy or chemoradiation.

DESIGN

Retrospective longitudinal study.

SETTING

Tertiary medical centres.

PARTICIPANTS

A total of 143 patients undergoing total laryngectomy for squamous cell carcinoma of the larynx or hypopharynx.

MAIN OUTCOME MEASURES

Overall postoperative complications and fistula formation.

RESULTS

Overall postoperative complications, fistula formation, wound infection, bleeding and wound necrosis within one year after total laryngectomy occurred in 56.6%, 42.3%, 31.0%, 11.3% and 9.2% of patients, respectively. Stenosis of the pharynx/oesophagus and stoma shrinkage within five years after surgery were each seen in 18.2% of cases. In 66.7% of cases, conservative treatment of the fistulas was chosen. Rehospitalisations within five years occurred for 44.8% with a median rate of 1.5 (range 1-11). Smoking status (P = 0.005 and 0.013) and chronic obstructive pulmonary disease (COPD) (P = 0.013 and 0.011) were significant risk factors for both overall postoperative complications and fistula formation in uni- and multivariate analysis. Tumour localisation in the hypopharynx was associated with overall postoperative complications (P = 0.036). Residual tumour or cancer recurrence was associated with late-onset fistulas (P < 0.001).

CONCLUSION

The frequencies of postoperative complications after total laryngectomy were comparable with similar international studies, although fistula formation rate is increasing in Denmark. We suggest optimising treatment of COPD and to further encourage to smoking cessation. We propose that development of fistulas >2 months after surgery prompts immediate biopsies. Additionally, we suggest standardised registration of surgical techniques to identify variables affecting the frequency of postoperative complications.

Conservative Treatment of Stress Urinary Incontinence In Women: A 10-Year (2004-2013) Scoping Review of the Literature

Stress urinary incontinence is a serious threat to the well-being of women world-wide. In this scoping review of the literature, we examined the most prominent research foci between the years 2004 and 2013. In this article, conservative treat-ment is operationalized as any non-surgical or non-pharmacological treatment modalities that could be carried out by specially trained nurses, physiotherapists, or physicians to treat stress urinary incontinence in women. The two most frequently described or systematically investigated treatment options identified in our review were 1) strengthening pelvic floor muscles with pelvic floor muscle training, including biofeedback and weighted vaginal cones; and 2) the use of intravaginal support devices, such as incontinence pessaries. Other treatment modalities were also explored in the literature review, such as intraurethral devices, behavioral and lifestyle interventions, products, and alternative therapies, such as acupuncture and acupressure. However, the focus of this article is on the two most frequently described options.
