The Flywheel Effect of Gender Role Expectations in Diverse Work Groups

Popular press suggests that gender diversity benefits the performance of work groups. However, decades of research indicate that such performance benefits of gender diversity are anything but a given. To account for this incongruity, in this conceptual paper we argue that the performance of gender-diverse work groups is often inhibited by self-reinforcing gender role expectations. We use the analogy of a flywheel to illustrate how gender role expectations tend to reinforce themselves via three mechanisms. Specifically, we argue that gender role expectations shape (1) the allocation of jobs, tasks, and responsibilities, (2) the behavior of perceivers, and (3) the behavior of target women and men. In turn, these three consequences of gender role expectations tend to confirm the initial gender role expectations, thus creating an automatic, self-reinforcing flywheel effect. Such self-reinforcing gender role expectations provide superficial impressions of individual women’s and men’s actual knowledge and abilities at best. We therefore further propose that each of the three mechanisms of the flywheel of gender role expectations negatively affects group performance to the extent that gender role expectations inaccurately capture group members’ actual knowledge and abilities. Because the extent to which work group members rely on gender role expectations depends on how they form impressions of others, we propose that individuals’ motivation to form accurate impressions is crucial for inhibiting the flywheel of gender role expectations. We close by advancing an agenda for future research on each of the three areas of interest in our conceptual analysis: the flywheel effect of gender role expectations, the consequences of this flywheel effect for group functioning, and ways to motivate group members to form accurate impressions

Diminished counterregulatory responses to meal-induced hypoglycemia 4 years after RYGB

PURPOSE: Post-bariatric hypoglycemia is a complication of bariatric surgery, especially Roux-en-Y gastric bypass (RYGB). The counterregulatory hormonal and sympathetic neural responses were measured during a previously reported meal test in which 48% had an almost asymptomatic hypoglycemic event. MATERIALS AND METHODS: Forty-four randomly selected patients 4 years after RYGB. A liquid meal test (MMT) after overnight fasting. Based on the glucose nadir during the MMT, patients were divided in a hypo group (glucose < 3.3 mmol/L) and a non-hypo group (glucose ≥ 3.3 mmol/L). Cortisol, epinephrine, norepinephrine, blood pressure, and heart rate were measured up to 180 min after ingestion of the meal. Incremental areas under the curve (iAUC), peak, and delta hormone responses after the glucose nadir were calculated. Parameters were compared between the hypo and non-hypo groups. RESULTS: A total of 21/44 (48%) had an almost asymptomatic hypoglycemic event. Cortisol and epinephrine responses in the hypo group were not increased compared to the non-hypo group, and there were no signs of increased sympathetic nerve activity. Peak and delta cortisol were lower in the hypo compared to the non-hypo group. Norepinephrine was higher in the hypo group especially in the time frame 60-120 and 120-180 min after start of the meal. CONCLUSION: No increase in epinephrine and a lower cortisol response to hypoglycemia were observed compared to normoglycemia during a meal test in patients after RYGB. Norepinephrine levels were higher in the hypo group. These findings may suggest that possible recurrent hypoglycemia after RYGB results in blunting of counterregulatory responses indicative of hypoglycemia-induced autonomic failure.

Joint involvement in RA starts predominantly in the hands:functional, clinical and imaging studies in clinically suspect arthralgia and during progression to RA

Objectives: It is unknown whether rheumatoid arthritis (RA) starts in hands or feet. To investigate this, we performed functional, clinical and imaging studies during progression from clinically suspect arthralgia (CSA) to RA. Additionally, we studied whether functional disabilities of hands/feet at CSA onset contribute to predicting RA development. Methods: 600 patients with CSA were followed for clinical inflammatory arthritis (IA) during median follow-up of 25 months, during which 99 developed IA. Functional disabilities were measured at baseline/4/12/24 months with the Health Assessment Questionnaire Disability Index (HAQ); HAQ items assessing hand disabilities and foot disabilities were selected. The course of disabilities towards IA development (here considered as t=0) was depicted by increasing incidences and analysed using linear mixed models. To evaluate robustness of findings, tender hand/foot joints and subclinical joint inflammation (measured with CE-1.5TMRI) of hand/foot were additionally studied. Associations between disabilities at CSA presentation (here t=0) and future IA development were studied using Cox regression in the total CSA population.Results: During IA development, hand disabilities occurred earlier and more frequently than foot disabilities. Despite both hand disabilities and foot disabilities rose significantly towards IA development, hand disabilities were more severe during this course (mean difference over time: 0.41 units, 95% CI 0.28 to 0.55, pPathophysiology and treatment of rheumatic disease

Consensus about GP interprofessional competencies:A nominal group study

BACKGROUND: Since the requirements for collaboration in primary care increase, effective interprofessional teamwork between general practitioners (GPs) and other primary care professionals is crucial. The need for more training in interprofessional collaborative competencies is widely recognised. However, existing competency frameworks do not sufficiently specify interprofessional collaboration to guide interprofessional competency development. AIM: Consensus among GPs and other primary care professionals on interprofessional competencies that GP and GP-trainees should learn. DESIGN & SETTING: Qualitative consensus study among Dutch GPs and other primary care professionals, all with expertise in primary care interprofessional collaborative practice. METHOD: Three nominal group sessions were held, each resulting in its own group consensus on GP interprofessional collaborative competencies. The researchers conducted a content analysis to merge and thematise the prioritised competencies into one list. Participants prioritised this list of competencies. A pre-set cut-off point was applied to determine the overall consensus on core GP interprofessional competencies. RESULTS: Eighteen professionals from nine different disciplines participated. The content analysis resulted in 31 unique competencies of which fourteen competencies were prioritised in the final ranking into three main themes: 1. Professional identity development and role definition by the GP. (three competencies); 2. Developing and executing shared care plans for individual patients (6); 3. Setting up and maintaining interprofessional collaborative partnerships.(5) CONCLUSION: An interprofessional group of experts reached consensus on 14 competencies within 3 themes. This framework provides a steppingstone for GPs to focus on their development regarding interprofessional collaboration

A new approach to child mental healthcare within general practice

Background: Child and adolescent mental health problems are frequently not identified and properly treated within general practice. Politicians in the Netherlands are promoting more primary healthcare treatment for mental health problems. The current study aims to evaluate an integrated primary mental healthcare approach for child and adolescent emotional and behavioural problems. This integrated approach allows general practitioners (GPs) to comprehensively explore the request for help, followed by an informed decision to refer, offer short-term treatment within general practice or postpone a decision by asking for additional consultations with youth mental health specialists. Method: The study is a naturalistic evaluation of Dutch general practices with pre-test and post-test comparison with controls based on data from Electronic Medical Records (EMR). The intervention started in September 2010. EMR data of all GP contacts with children aged 4 to 18 (including diagnosis, prescriptions, referrals) from practices involved in the intervention was used from 1 January 2009 to 31 December 2012. Extra codes were added to the EMR to record aspects of the intervention. Comparable EMR data was used in control practices in 2011. Results: GPs in the intervention group were able to identify more emotional and behavioural problems after the integrated service had started. They also identified more problems than GPs in the control practices. They were already reluctant to prescribe psychopharmacological medication to children before the intervention, and levels of prescription at intervention GP practices remained low for psychotropic drugs compared to control practices. Referral rates to mental healthcare remained relatively steady after the introduction of the integrated service, but referrals switched from specialized to primary mental healthcare. Conclusion: An integrated mental healthcare approach within general practice may lead to an increase in detected psychosocial problems among children, and these problems can mainly be treated within the primary care setting

No association between thickening fraction of the diaphragm and extubation success in ventilated children

Introduction: In mechanically ventilated adults, thickening fraction of diaphragm (dTF) measured by ultrasound is used to predict extubation success. Whether dTF can also predict extubation success in children is unclear. Aim: To investigate the association between dTF and extubation success in children. Second, to assess diaphragm thickness during ventilation and the correlation between dTF, diaphragm thickness (Tdi), age and body surface. Method: Prospective observational cohort study in children aged 0–18 years old with expected invasive ventilation for &gt;48 h. Ultrasound was performed on day 1 after intubation (baseline), day 4, day 7, day 10, at pre-extubation, and within 24 h after extubation. Primary outcome was the association between dTF pre-extubation and extubation success. Secondary outcome measures were Tdi end-inspiratory and Tdi end-expiratory and atrophy defined as &lt;10% decrease of Tdi end-expiratory versus baseline at pre-extubation. Correlations were calculated with Spearman correlation coefficients. Inter-rater reliability was calculated with intraclass correlation (ICC). Results: Fifty-three patients, with median age 3.0 months (IQR 0.1–66.0) and median duration of invasive ventilation of 114.0 h (IQR 55.5–193.5), were enrolled. Median dTF before extubation with Pressure Support 10 above 5 cmH2O was 15.2% (IQR 9.7–19.3). Extubation failure occurred in six children, three of whom were re-intubated and three then received non-invasive ventilation. There was no significant association between dTF and extubation success; OR 0.33 (95% CI; 0.06–1.86). Diaphragmatic atrophy was observed in 17/53 cases, in three of extubation failure occurred. Children in the extubation failure group were younger: 2.0 months (IQR 0.81–183.0) vs. 3.0 months (IQR 0.10–48.0); p = 0.045. At baseline, pre-extubation and post-extubation there was no significant correlation between age and BSA on the one hand and dTF, Tdi- insp and Tdi-exp on the other hand. The ICC representing the level of inter-rater reliability between the two examiners performing the ultrasounds was 0.994 (95% CI 0.970–0.999). The ICC of the inter-rater reliability between the raters in 36 paired assessments was 0.983 (95% CI 0.974–0.990). Conclusion: There was no significant association between thickening fraction of the diaphragm and extubation success in ventilated children.</p

Newer long-acting insulin prescriptions for patients with type 2 diabetes: Prevalence and practice variation in a retrospective cohort study

BACKGROUND: Little is known about prescription patterns of expensive non-recommended newer long-acting insulins (glargine 300 U/mL and degludec) for patients with type 2 diabetes mellitus (T2DM). AIM: To identify practice variation in, and practice- and patient-related characteristics associated with, the prescription of newer long-acting insulins to patients with T2DM in primary care. DESIGN AND SETTING: A retrospective cohort study in Dutch general practices (Nivel Primary Care Database). METHOD: A first prescription for intermediate or long-acting insulins in 2018 was identified in patients aged ≥40 years using other T2DM drugs. Per practice, the median percentage and interquartile range (IQR) of patients with newer insulin prescriptions were calculated. Multilevel logistic regression models were constructed to calculate intraclass correlation coefficients (ICCs) and quantify the association of patient and practice characteristics with prescriptions for newer insulins (odds ratios [ORs] and 95% confidence intervals [CIs]). RESULTS: In total, 7757 patients with prescriptions for intermediate or long-acting insulins from 282 general practices were identified. A median percentage of 21.2% (IQR 12.5–36.4%) of all patients prescribed intermediate or long-acting insulins per practice received a prescription for newer insulins. After multilevel modelling, the ICC decreased from 20% to 19%. Female sex (OR 0.77, 95% CI = 0.69 to 0.87), age ≥86 years compared with 40–55 years (OR 0.22, 95% CI = 0.15 to 0.34), prescriptions for metformin (OR 0.66, 95% CI = 0.53 to 0.82), sulfonylurea (OR 0.58, 95% CI = 0.51 to 0.66), or other newer T2DM drugs (OR 3.10, 95% CI = 2.63 to 3.66), and dispensing practices (OR 1.78, 95% CI = 1.03 to 3.10) were associated with the prescription of newer insulins. CONCLUSION: The inter-practice variation in the prescription of newer insulins is large and could only be partially explained by patient- and practice-related differences. This indicates substantial opportunities for improvement

Weight loss in adult male Wistar rats by Roux-en-Y gastric bypass is primarily explained by caloric intake reduction and presurgery body weight

Relative to feeding an LF diet, continued feeding an HF/S diet does not negatively impact recovery from RYGB surgery in rats. Relative to feeding an LF diet, continued feeding an HF/S diet promotes RYGB-induced weight loss. The RYGB-induced weight loss is primarily explained by reduced cumulative EI and higher preoperative body weight, leading to comparably low levels of body fat content in HF/S and LF feeding rats

Psychosocial function of Dutch children with cancer and their caregivers during different phases of the COVID-19 pandemic

We compared psychosocial functioning of children with cancer and their caregivers in several phases of the coronavirus disease 2019 (COVID-19) pandemic to before COVID-19. One or more questionnaires on health-related quality of life (HRQoL) or fatigue of children or distress of their caregivers was available from 1644 families. In children with cancer, HRQoL was stable throughout the COVID-19 pandemic. Fatigue was slightly lower and sleep somewhat better during the pandemic than before. Caregiver distress was lower in the first pandemic phase, but increased to pre-COVID-19 levels in later phases, indicating that the length and consequences of the pandemic may be weighing on them
