RESUMO

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 (dSMC = 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 (dSMC = 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.

RESUMO

BACKGROUND: Electrical cardioversion (ECV) is a common procedure to terminate persistent atrial fibrillation (AF). The recurrence rate is high, and the patients often fail to recognize AF recurrence. OBJECTIVES: The aim of the study was to evaluate the feasibility of patient-managed electrocardiography (ECG) to detect the time to AF recurrence after ECV. METHODS: PRE-ELECTRIC (predictors for recurrence of atrial fibrillation after electrical cardioversion) is a prospective, observational study. Patients ≥18 years of age scheduled for ECV of persistent AF at Bærum Hospital were eligible for inclusion in the study. Time to recurrence of AF was detected by thumb ECG, recorded twice daily and whenever experiencing symptoms. The observation period was 28 days. We defined adherence as the observed number of days with ECG recordings divided by the expected number of days with ECG recordings. Study personnel contacted the participants by phone to assess their awareness of AF recurrence after a recurrence was detected in the thumb ECG. RESULTS: The study enrolled 200 patients scheduled for ECV of persistent AF at Bærum Hospital between 2018 and 2022. The mean age was 66.2 ± 9.3 years, and 21.0% (42/200) were women. The most frequent comorbidities were hypertension (n = 94, 47.0%) and heart failure (n = 51, 25.5%). A total of 164 participants underwent ECV of AF. The procedure was initially successful in 90.9%, of which 50.3% had a recurrence of AF within 4 weeks. The median time to recurrence was 5 days. Among the cardioverted participants, 123 (75.0%) had no missing days of thumb ECG recording during the observation period, and 97.0% had ≤3 missing days. More than a third (37.3%) of the participants with AF recurrence were unaware of the recurrence at the time of contact. Women were older and more symptomatic than men but had similar outcomes after ECV. CONCLUSIONS: Recurrence of AF after ECV was common. Using patient-managed thumb ECG was a feasible method to detect AF recurrence following ECV. Further studies are needed to investigate whether patient-managed ECG after ECV can optimize AF treatment.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The National Early Warning Score 2 (NEWS2) is a scoring tool predictive of poor outcome in hospitalised patients. Older patients with COVID-19 have increased risk of poor outcome, but it is not known if frailty may impact the predictive performance of NEWS2. We aimed to investigate the impact of frailty on the performance of NEWS2 to predict in-hospital mortality in patients hospitalised due to COVID-19. METHODS: We included all patients admitted to a non-university Norwegian hospital due to COVID-19 from 9 March 2020 until 31 December 2021. NEWS2 was scored based on the first vital signs recorded upon hospital admission. Frailty was defined as a Clinical Frailty Scale score ≥ 4. The performance of a NEWS2 score ≥ 5 to predict in-hospital mortality was assessed with sensitivity, specificity and area under the receiver operating characteristic curve (AUROC) according to frailty status. RESULTS: Out of 412 patients, 70 were aged ≥ 65 years and with frailty. They presented less frequently with respiratory symptoms, and more often with acute functional decline or new-onset confusion. In-hospital mortality was 6% in patients without frailty, and 26% in patients with frailty. NEWS2 predicted in-hospital mortality with a sensitivity of 86%, 95% confidence interval (CI) 64%-97% and AUROC 0.73, 95% CI 0.65-0.81 in patients without frailty. In older patients with frailty, sensitivity was 61%, 95% CI 36%-83% and AUROC 0.61, 95% CI 0.48-0.75. CONCLUSION: A single NEWS2 score at hospital admission performed poorly to predict in-hospital mortality in patients with frailty and COVID-19 and should be used with caution in this patient group.

RESUMO

BACKGROUND: Waves of infection have formed the pattern of the COVID-19 pandemic. A wave dominated by the delta variant of the SARS-CoV-2 virus in autumn 2021 was superseded by the omicron variant over the course of a few weeks around Christmas. We describe how this transition affected the population of patients admitted to a Norwegian local hospital with COVID-19. MATERIAL AND METHOD: All patients admitted to Bærum Hospital with confirmed SARS-CoV-2 virus were included in a quality study which aimed to describe patient characteristics and clinical course. We present patients admitted in the periods 28 June 2021-31 December 2021 and 1 January 2022-12 June 2022, described here as the delta wave and the omicron wave. RESULTS: The SARS-CoV-2-virus was confirmed in a total of 144 patients who were admitted during the delta wave, and in 261 patients during the omicron wave, where 14/144 (10 %) and 89/261 (34 %) were admitted for reasons other than COVID-19. Patients with COVID-19 during the delta wave were younger on average (59 vs. 69 years) and had a lower Charlson comorbidity index score (2.6 vs. 4.9) and a lower Clinical Frailty Scale score (2.8 vs. 3.7) than patients in the omicron wave. Among 302/405 patients admitted with COVID-19 as the principal diagnosis, 88/130 (68 %) patients had respiratory failure during the delta wave and 59/172 (34 %) during the omicron wave, with a median number of 8 bed days (interquartile range 5-15) and 5 (interquartile range 3-8). INTERPRETATION: The transition from the wave of infection that was dominated by the delta variant of the SARS-CoV-2 virus to the wave dominated by the omicron variant had a considerable effect on the characteristics and clinical course of patients admitted to hospital with SARS-CoV-2 infection.

RESUMO

BACKGROUND: The objective of this article is to summarise the course of illness and treatment for patients with COVID-19 admitted to Bærum Hospital since the start of the pandemic. MATERIAL AND METHOD: We present data from a prospective observational study with the aim of systematising knowledge about patients admitted because of COVID-19. All patients admitted to Bærum Hospital up to and including 28 June 2021 were included. The results are presented for three waves of admissions: 9 March-23 June 2020, 21 September 2020-28 February 2021 and 1 March-28 June 2021. RESULTS: A total of 300 patients, divided into 77, 101 and 122 in the three waves respectively, were admitted because of COVID-19. The number of hospital deaths during the three waves was 14 (18 %), 11 (11 %) and 5 (4 %) respectively. The average age of the patients was 67.6 years in the first wave and 53.3 years in the third wave. Altogether 204 patients (68 %) received medical oxygen or ventilation support, and 31 of these (10 % of all the patients) received invasive ventilation support. Non-invasive ventilation support was used as the highest level of treatment in 4 (8 %), 9 (13 %) and 17 (20 %) patients with respiratory failure in the three waves respectively. In the second and third wave, 125 out of 152 patients with respiratory failure (82 %) were treated with dexamethasone. INTERPRETATION: Differences in patient characteristics and changes to treatment methods, such as the use of dexamethasone and non-invasive ventilation support, may have contributed to the apparent fall in mortality from the first to the third wave. Conditions that are not registered in the study, such as vaccination status, may also have impacted on mortality.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The course of disease, complications and hospital mortality among patients with COVID-19 admitted to Norwegian hospitals has not been widely described. The purpose of this study was to survey patients with COVID-19 admitted to a local hospital. MATERIAL AND METHOD: The data were retrieved from a prospective observational study of all patients admitted with COVID-19 to Bærum Hospital since the start of the coronavirus outbreak. RESULTS: A total of 73 patients with COVID-19 admitted in the period 9 March 2020-7 May 2020 were included. The mean age was 67.9 years, and 43 patients (59 %) were men. The average number of days hospitalised was 10.1. Altogether 19 patients (26 %) had a very severe course of disease, and 14 (19 %) died during their stay in hospital. The mean age among the patients who died was 79.5 years. A total of 49 patients (67 %) had hypoxaemia and required oxygen therapy for an average of 10.1 days. Of these, 9 patients were given invasive respiratory support for a median 18 days. Symptoms of delirium occurred in 26 patients (36 %) and was the most frequent non-respiratory complication. INTERPRETATION: The majority of the patients hospitalised with COVID-19 needed prolonged oxygen therapy, and there was a high incidence of severe complications.

RESUMO

BACKGROUND: The COVID-19 outbreak is presenting the health system with new challenges, and there is a great need for knowledge about symptoms, clinical findings and course of illness in patients admitted to Norwegian hospitals with COVID-19. MATERIAL AND METHOD: In this observational qualitative study, all patients admitted to a Norwegian local hospital (Bærum Hospital) with proven COVID-19 infection were included consecutively from the start of the outbreak. We present here patient characteristics, symptoms, clinical findings, experience of using clinical scoring systems and course of illness based on data in medical records. RESULTS: In the period 9-31 March 2020, 42 patients, of whom 28 (67 %) were men, were admitted to hospital with COVID-19 infection. The median age was 72.5 years (range 30-95). Fever (79 %), reduced general condition (79 %), dyspnoea (69 %) and cough (67 %) were the most common symptoms. A total of nine patients (21 %) had a critical course of illness with treatment in the Intensive Care Department and/or death during their stay in hospital. Patients with a critical course had a higher average score on National Early Warning Score 2 (NEWS2) on admission (7.6 vs 3.3). Only one of the most severely ill patients scored ≥ 2 on the quick Sepsis-related Organ Failure Assessment (qSOFA) on admission. INTERPRETATION: Most patients admitted to our hospital with COVID-19 had a fever and respiratory tract symptoms. A high percentage of patients had a critical course of illness. A NEWS2 score of ≥ 5 on admission may be a useful aid in identifying patients at risk of a critical course of illness, while CRB-65 and qSOFA score ≥ 2 proved to be of little usefulness for this purpose in our material.

RESUMO

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.

RESUMO

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.

RESUMO

Maternal behavior (MB) is a complex response to infant cues, orchestrated by postpartum neurophysiology. Although mesolimbic dopamine contributes toward MB, little is known about real-time dopamine fluctuations during the postpartum period. Thus, we used fast-scan cyclic voltammetry to measure individual dopamine transients in the nucleus accumbens of early postpartum rats and compared them with dopamine transients in virgins and in postpartum females exposed to cocaine during pregnancy, which is known to disrupt MB. We hypothesized that dopamine transients are normally enhanced postpartum and support MB. In anesthetized rats, electrically evoked dopamine release was larger and clearance was faster in postpartum females than in virgins and gestational cocaine exposure blocked the change in clearance. In awake rats, control mothers showed more dopamine transients than cocaine-exposed mothers during MB. Salient pup-produced stimuli may contribute toward differences in maternal phasic dopamine by evoking dopamine transients; supporting the feasibility of this hypothesis, urine composition (glucose, ketones, and leukocytes) differed between unexposed and cocaine-exposed infants. These data, resulting from the novel application of fast-scan cyclic voltammetry to models of MB, support the hypothesis that phasic dopamine signaling is enhanced postpartum. Future studies with additional controls can delineate which aspects of gestational cocaine reduce dopamine clearance and transient frequency.

Define the application of Swanson's Middle Range Theory of Caring in care aides' relational care practices for nursing home residents. 2. Describe how nursing home managers can empower care aides to provide care. DISCLOSURE STATEMENT Neither the planners nor the author have any conflicts of interest to disclose. The current study was a qualitative focused ethnography aimed at exploring the complexities of care; working environments; and knowledge, skills, and efforts of care aides who work in nursing homes. Over the past decade, dramatic shifts in staffing patterns in Canadian nursing homes have transformed care aides' assistive and caring roles. Care aides are now the central and most accessible service providers to nursing home residents. In the current article, the authors (a) conceptualize care aide work as caring rather than caring activities, (b) explore relational care as a foundational and significant component of care aide work, (c) interpret care aides' relational care practices through the lens of Swanson's Middle Range Theory of Caring, and (d) describe how nursing home managers can empower care aides to do this work.

RESUMO

BACKGROUND AND PURPOSE: The Relational Care Scale (RCS) is a Canadian evaluative instrument designed to measure nursing home residents' perceptions of care aides' relational abilities. Care aides' abilities to be reliable and empathetic with nursing home residents are very important determinants of quality of care, but few instruments are designed specifically for residents or focus exclusively on these determinants. Initially developed and tested in metropolitan teaching-affiliated nursing homes in Ontario, we expanded testing by reevaluating the psychometric properties of the RCS in 5 rural nursing homes in British Columbia. METHOD: There were 62 residents living in 5 rural nursing homes who completed 3 instruments: the RCS under investigation, the Experiences in Close Relationships-Relationship Structures (ECR-RS) questionnaire to test for convergent validity, and the Lubben Social Network Scale-6 (LSNS-6) to test for discriminant validity. RESULTS: The reliability of the RCS was strongly supported (Cronbach's alpha = .90, item-total correlation > .77). Consistent with previous testing, a unidimensional internal structure was extracted. A moderate to strong correlation between the RCS and the Anxiety and Avoidance subscales of the ECR-RS supported convergent validity of the instrument. Last, partial support was obtained for the discriminant validity of the RCS. CONCLUSIONS: The RCS was easy to use for both residents and researchers. Expanded testing demonstrated its recurring reliability and validity.

RESUMO

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.

RESUMO

Increased sensitivity to ovarian hormone changes is implicated in the etiology of reproductive mood disorders across the female lifespan, including menstrually-related mood disorders, perinatal mood disorders, and perimenopausal depression. Developing a method to accurately quantify sensitivity to endogenous hormone fluctuations may therefore facilitate the prediction and prevention of these mental health conditions. Here, we propose one such method applying a synchrony analysis to compute time-lagged cross-correlations between repeated assessments of endogenous hormone levels and self-reported affect. We apply this method to a dataset containing frequent repeated assessments of affective symptoms and the urinary metabolites of estradiol (E2) and progesterone (P4) in 94 perimenopausal females. These preliminary findings suggest that, with further refinement and validation, the proposed method holds promise as a diagnostic tool to be used in clinical practice and to advance research investigating the etiology of reproductive mood disorders.

RESUMO

This case study presents details of the life of one older man who lived in seclusion and squalor, surrounded by hoarded possessions. This man was one participant of a focused ethnography of eight older adults who received home care. All participants in the original ethnography were identified by their community care coordinators as exhibiting hoarding behaviors. The case study presented here provides rich narrative and photographic detail in order to add strength to what has already been presented in previous research articles about compulsive acquisition. The narratives reveal examples of debilitating dysfunction, distress associated with decision making, broad acquisition of free things, compulsive buying, and ritualistic discarding. Quotes included in the case study stem from the original ethnography.

RESUMO

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.
