Gender and leadership aspiration: the impact of organizational identification
Purpose Although nowadays more women occupy leadership roles, they still are a minority. Because aspiration is a precursor of advancement, examining conditions fostering female leadership aspiration is important. A neglected perspective is the impact of organizational identification. Identification can be argued to foster leadership aspiration because the essence of leadership is the pursuit of collective interests, and identification motivates such pursuits. The paper aims to discuss these issues. Design/methodology/approach A cross-sectional survey design with an n=400 fulltime employed men and women, working for various organizations was selected. Findings The initial prediction was that identification is more important to women’s leadership aspiration to the extent that gender is associated with communal orientation, because women tend to have stronger communal orientation with associated greater affiliation needs, and organizational identification can be expected to cater to those needs. The communal orientation by organizational identification interactive influence on leadership aspiration was supported. Also, the indirect effect of gender on leadership aspiration via this interactive influence of communal orientation and organizational identification was supported. Research limitations/implications Due to the selected survey approach the data are correlational and as a result no reference to matters of causality can be made. Thus (field) experimental data is needed to confirm these findings. Practical implications Within the paper the discussion focuses on the importance of creating an environment that is more conducive to organizational identification and as such speaks to the communal orientation – being more pronounced among women – to act in favor of the organization by aspiring leadership positions. Originality/value The presented results depict an important step toward understanding how organizational identification and communal orientation interact and how they interact with women’s leadership aspiration
Relationship Between Baseline Prostate-specific Antigen on Cancer Detection and Prostate Cancer Death:Long-term Follow-up from the European Randomized Study of Screening for Prostate Cancer
Background: The European Association of Urology guidelines recommend a risk-based strategy for prostate cancer screening based on the first prostate-specific antigen (PSA) level and age. Objective: To analyze the impact of the first PSA level on prostate cancer (PCa) detection and PCa-specific mortality (PCSM) in a population-based screening trial (repeat screening every 2–4 yr). Design, setting, and participants: We evaluated 25 589 men aged 55–59 yr, 16 898 men aged 60–64 yr, and 12 936 men aged 65–69 yr who attended at least one screening visit in the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial (screening arm: repeat PSA testing every 2–4 yr and biopsy in cases with elevated PSA; control arm: no active screening offered) during 16-yr follow-up (FU). Outcome measurements and statistical analysis: We assessed the actuarial probability for any PCa and for clinically significant (cs)PCa (Gleason ≥7). Cox proportional-hazards regression was performed to assess whether the association between baseline PSA and PCSM was comparable for all age groups. A Lorenz curve was computed to assess the association between baseline PSA and PCSM for men aged 60–61 yr. Results and limitations: The overall actuarial probability at 16 yr ranged from 12% to 16% for any PCa and from 3.7% to 5.7% for csPCa across the age groups. The actuarial probability of csPCa at 16 yr ranged from 1.2–1.5% for men with PSA <1.0 ng/ml to 13.3–13.8% for men with PSA ≥3.0 ng/ml. The association between baseline PSA and PCSM differed marginally among the three age groups. A Lorenz curve for men aged 60–61 yr showed that 92% of lethal PCa cases occurred among those with PSA above the median (1.21 ng/ml). In addition, for men initially screened at age 60–61 yr with baseline PSA <2 ng/ml, further continuation of screening is unlikely to be beneficial after the age of 68–70 yr if PSA is still <2 ng/ml. No case of PCSM emerged in the subsequent 8 yr (up to age 76–78 yr). A limitation is that these results may not be generalizable to an opportunistic screening setting or to contemporary clinical practice. Conclusions: In all age groups, baseline PSA can guide decisions on the repeat screening interval. Baseline PSA of <1.0 ng/ml for men aged 55–69 yr is a strong indicator to delay or stop further screening. Patient summary: In prostate cancer screening, the patient's baseline PSA (prostate-specific antigen) level can be used to guide decisions on when to repeat screening. The PSA test when used according to current knowledge is valuable in helping to reduce the burden of prostate cancer.</p
Gender and Leadership Aspiration:Supervisor Gender, Support, and Job Control
Understanding the role of leadership aspiration in the under-representation of female leaders is important, because aspiration is a key predictor of hierarchical advancement. A neglected perspective in the relationship between gender and leadership aspiration is the gender of the individual's supervisor. Supervisors can play an important role in providing support and in engendering a sense of control, and both support and control are precursors to leadership aspiration. Yet, supervisors may also act on gender biases that discourage women's leadership aspiration. We argue that there is an interaction between supervisor and subordinate gender such that men experience relatively high levels of support and control regardless of supervisor gender, whereas women experience more support and control and as a result display higher leadership aspiration with a female supervisor. A survey of N = 402 men and women supported these hypotheses regarding the subordinate gender by supervisor gender interactive influence on leadership aspiration, support, control, and the mediated moderation model
Dexamethasone and long-term survival in bacterial meningitis
Background: Data on the long-term effect of dexamethasone on survival in bacterial meningitis are lacking. Methods: A long-term follow-up study of the European Dexamethasone in Adulthood Bacterial Meningitis Study was performed. In this double-blind, randomized clinical trial, 301 patients were randomly assigned to receive adjunctive dexamethasone (n = 157) or placebo (n = 144) between June 1993 and December 2001. We obtained survival data of patients using the DutchMunicipal Population Register. Results: Death had occurred in 32 of 301 included patients (11%) at the primary outcome measurement 8 weeks after randomization. Follow-up was obtained for 228 of 246 evaluable patients (93%), with median follow-up of 13 years. Overall, 31 of 144 patients (22%) in the dexamethasone group died and 44 of 134 patients (33%) in the placebo group died (log-rank p = 0.029). After the primary end point of the study at 8 weeks, 20 patients in the dexamethasone group died and 23 patients in the placebo group died (log-rank p = 0.27), with age being the sole predictor of death (p <0.001). Conclusions: In adults with community-acquired bacterial meningitis, the survival benefit from adjunctive dexamethasone therapy is obtained in the acute phase of the disease and remains for years. Classification of Evidence: This study of a population of Dutch patients shows Class III evidence that dexamethasone provides an extended survival benefit in patients treated for bacterial meningitis, and this survival benefit extends as long as 20 years.

Clinical features, treatment and outcome in neurosarcoidosis: systematic review and meta-analysis
Neurosarcoidosis is a rare variant of sarcoidosis and is only described in small cohort studies. We define clinical features, treatment and outcome of patients with neurosarcoidosis over the last 35 years. We performed a systematic review and meta-analysis of studies on neurosarcoidosis published between 1980 and 2016. Studies were included if they reported at least 5 cases. Studies describing one specific neurological presentation were excluded. We identified 29 articles describing 1088 patients diagnosed between 1965 and 2015. Neurosarcoidosis occurred in 5% of patients with systemic sarcoidosis. Mean age at presentation was 43 years and neurological symptoms were the first clinical manifestation of sarcoidosis in 52%. The most commonly reported feature of neurosarcoidosis was cranial neuropathy in 55%, with the facial and optic nerve most commonly affected, followed by headache in 32%. Pleiocytosis and elevated CSF protein were found in 58 and 63%. MRI of the brain showed abnormalities in 70%. Chest X-ray, chest CT, or gallium-67-scintigraphy showed findings consistent with sarcoidosis in 60%, 70% and 69%, respectively. First line therapy with corticosteroids was initiated in 434 of 539 patients (81%). Second and third line therapy was started in 27 and 9%. Outcome consisted of complete remission in 27%, incomplete remission in 32%, stable disease in 24%, deterioration in 6% and death in 5%. Neurosarcoidosis has a heterogeneous clinical presentation and the diagnosis can be difficult because of low sensitivity of ancillary investigations. New treatments have emerged, but nevertheless one third of patients do not respond to treatment. Prospective cohort studies and RCTs on treatment are urgently neede
Whole genome sequencing identifies variants associated with sarcoidosis in a family with a high prevalence of sarcoidosis
Objective: We studied genetic risk factors associated with sarcoidosis within a family with a high prevalence of this disease. Methods: We studied 41 members of a family with a high rate of sarcoidosis, including an index patient with treatment-resistant neurosarcoidosis. Whole genome sequencing was performed for six affected family members and variations associated with loss of function were filtered out as candidate genes. Findings were validated by using amplicon sequencing within all 41 family members with DNA available and candidate genes were screened on absence and presence within the sarcoidosis affected and non-affected. Results: Family members (n = 61) from 5 generations were available for participation including 13 subjects diagnosed with sarcoidosis (20%). Analyses identified 36 candidate variants within 34 candidate genes. Variations within three of these genes (JAK2, BACH2, and NCF1) previously have been associated with autoimmune diseases. Conclusions: We identified 34 genes with a possible role in the etiology of sarcoidosis, including JAK2. Our results may suggest evaluation of JAK inhibitors in treatment-resistant sarcoidosis.Key Points• JAK2 has a potential role in the etiology of sarcoidosis and is a potential therapeutic target.• We identified 33 additional candidate genes of which BACH2 and NCF1 have been previously associated with autoimmune disease
Cryptococcal meningitis complicating sarcoidosis
Cryptococcal meningitis is an uncommon but severe complication of sarcoidosis. We present 2 patients with cryptococcal meningitis complicating sarcoidosis and compared findings with 38 cases reported in the literature. When analyzing our patients and 38 cases reported in the literature, we found that median age of sarcoidosis patients with cryptococcal meningitis was 39 years (range 30-48); 27 of 33 reported cases (82%) had a history of sarcoidosis. Only 16 of 40 patients (40%) received immunomodulating therapy at the time of diagnosis of cryptococcal meningitis. The diagnosis of cryptococcal meningitis was delayed in 17 of 40 patients (43%), mainly because of the initial suspicion of neurosarcoidosis. Cerebrospinal fluid (CSF) examination showed mildly elevated white blood cell count (range 23-129/mm). Twenty-nine of 32 cases (91%) had a positive CSF culture for Cryptococcus neoformans and 25 of 27 cases (93%) had a positive CSF C neoformans antigen test. CD4 counts were low in all patients in whom counts were performed (84-228/mL). Twelve patients had an unfavorable outcome (32%), of which 7 died (19%) and 24 patients (65%) had a favorable outcome. The rate of unfavorable outcome in patients with a delayed diagnosis was 7 of 17 (41%) compared to 5 of 28 (21%) in patients in whom diagnosis was not delayed. Cryptococcal meningitis is a rare but life-threatening complication of sarcoidosis. Patients were often initially misdiagnosed as neurosarcoidosis, which resulted in considerable treatment delay and worse outcome. CSF cryptococcal antigen tests are advised in patients with sarcoidosis and meningiti
Many faces of neurosarcoidosis: from chronic meningitis to myelopathy
Purpose of review Neurosarcoidosis occurs in 5% of patients with sarcoidosis and can be difficult to diagnose. In this review we discuss the most recent advances in our understanding of the disease, describing clinical characteristics, diagnostic process, treatment, and prognosis. Recent findings Clinical presentation is heterogeneous with most patients presenting with cranial nerve palsy, headache, or sensory abnormalities. Patients are classified according to probability of the diagnosis with the Zajicek criteria. In these criteria, histopathological confirmation of noncaseating granulomas in affected tissue outside the nervous system is key. Radiological abnormalities on neuroimaging are nonspecific. No biomarkers have been described that adequately identify patients with sarcoidosis. However, soluble interleukin-2 receptor is a relatively novel biomarker that may be useful. In addition to HRCT scan, F-18-FDG PET-CT scanning can identify occult locations of disease activity and aid in obtaining pathological confirmation. Despite the use of new therapies, still a third of patients remains stable, deteriorate, or die. Summary Diagnosing and treating patients with neurosarcoidosis remains a challenge. Long-term prospective studies evaluating patients suspected of neurosarcoidosis are needed to assess sensitivity and specificity of ancillary investigations and diagnostic criteria. Furthermore, future studies are needed to evaluate the prognosis and the optimal treatment strateg
