Long-term safety in patients with recurrent ovarian cancer treated with niraparib versus placebo: Results from the phase III ENGOT-OV16/NOVA trial

OBJECTIVE

Niraparib is a poly(ADP-ribose) polymerase (PARP) inhibitor approved for use in heavily pretreated patients and as maintenance treatment in patients with newly-diagnosed or recurrent ovarian cancer following a response to platinum-based chemotherapy. We present long-term safety data for niraparib from the ENGOT-OV16/NOVA trial.

METHODS

This multicenter, double-blind, randomized, controlled phase III trial evaluated the efficacy and safety of niraparib for the treatment of recurrent ovarian cancer. Patients were randomly assigned 2:1 to receive either once-daily niraparib 300 mg or placebo. Two independent cohorts were enrolled based on germline BRCA mutation status. The primary endpoint was progression-free survival, reported previously. Long-term safety data were from the most recent data cutoff (September 2017).

RESULTS

Overall, 367 patients received niraparib 300 mg once daily. Dose reductions due to TEAEs were highest in month 1 (34%) and declined every month thereafter. Incidence of any-grade and grade ≥ 3 hematologic and symptomatic TEAEs was also highest in month 1 and subsequently declined. Incidence of grade ≥ 3 thrombocytopenia decreased from 28% (month 1) to 9% and 5% (months 2 and 3, respectively), with protocol-directed dose interruptions and/or reductions. Acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) were reported in 2 and 6 niraparib-treated patients, respectively, and in 1 placebo patient each. Treatment discontinuations due to TEAEs were <5% in each month and time interval measured.

CONCLUSION

These data demonstrate the importance of appropriate dose reduction according to toxicity criteria and support the safe long-term use of niraparib for maintenance treatment in patients with recurrent ovarian cancer.

Which objective sleep elements predict children's perceptions of good sleep quality? A preliminary investigation based on polysomnography and actigraphy

OBJECTIVES

Objective sleep elements that underlie child ratings of sleep quality are largely unknown. Child-based sleep recommendations, therefore, typically focus on duration. An expert panel recently provided specific recommendations regarding objective sleep parameters that correspond with higher quality sleep, but child-based studies from which to draw conclusions were notably limited. The present study used actigraphy and polysomnography to explore sleep continuity and architectural variables that correspond with higher ratings of sleep quality in a sample of school-aged children.

METHODS

Fifty-two healthy, prepubertal children (aged 7-11 years) completed one night of unattended ambulatory polysomnography at home with concurrent actigraphy and provided sleep quality ratings the following morning. Associations between sleep variables and subjective ratings were examined using polynomial regression models to examine potential linear and nonlinear relationships.

RESULTS

In contrast to findings among adults, total sleep time, sleep onset latency, and sleep efficiency values were unrelated to child ratings of sleep quality. Wake after sleep onset (WASO) showed a curvilinear (reversed j-shaped) relationship such that perceptions of sleep quality were high when WASO values were less than approximately 30 minutes. For sleep architecture, N1% showed a significant quadratic association with sleep quality such that N1% between 2% and 6% corresponded with high sleep quality ratings.

CONCLUSIONS

Our findings support expert recommendations regarding WASO values that predict high quality sleep in children, but also await replication. There is need for additional research aimed at understanding objective sleep elements and other influences of children's perceptions of sleep quality using linear and nonlinear models.

Antipsychotic Overdosing and Polypharmacy in Schizophrenic Delinquents Explored

A logistic regression model for 289 cases of schizophrenic offenders in a Swiss forensic hospital between 1995 and 2016 revealed the following factors for above average levels of antipsychotic overdosing and polypharmacy: Odds for overdosing increased in absence of a personality disorder (237%), for each point increase in emotional withdrawal (63.5%) and motor retardation (71.7%), and decreased for poor rapport (42.3%) recorded at admission. Odds for polypharmacy increased with complaints about physicians (157%), for each point increase in IQ (3.6%; range = 65-131, M = 92, SD = 14), reduction of the security level of the ward (36.8%; four levels), and for each point increase in poor attention (27.6%) at admission. It decreased with each previous conviction (10.9%; range = 1-21, M = 3, SD = 2), breaking of rules (46.4%) and the administration of compulsory measures (55.7%) on the ward, a poor legal prognosis (29.4%, four levels), and each point increase in grandiosity (40.3%), passive social withdrawal (42.3%), and depressive symptoms (38.7%) at admission.

Age-related morphology and function of human arterial endothelial cells

Endothelialization of cardiovascular implants is regarded as a promising strategy for long-term compatibility. While umbilical vein endothelial cells are typically applied in research, human arterial endothelial cells (HAEC) from elderly donors would be the obvious source for autologous cellularization strategies.In our approach, HAEC from 16 donors of varying age (16-63 years) were divided into two groups (<30 years and >30 years) and analyzed regarding morphology, viability, proliferation, function and senescence status.No age-related differences were found regarding morphology, viability, density, prostacyclin and nitrite secretion or collagen and laminin production. However, the metabolic activity was slightly decreased (p = 0.0374) and the membrane integrity marginally impaired (p = 0.0404) in cells from older donors. Two out of three senescence assays detected more senescence markers in cells from older donors.According to the assays applied here, HAEC from young and elderly donors up to the age of 63 years could be judged equally suitable for autologous cellularization strategies. However, this finding should be regarded with caution due to the extremely large variability between individual donors. Further studies comprising a larger sample size are necessary to investigate this issue more thoroughly.

Sleep Patterns and Anxiety in Children Interact to Predict Later Suicidal Ideation

Elevated levels of childhood anxiety pose risk for suicide; however, factors that accentuate this risk are unknown. Seventy-one children participated in a longitudinal study investigating anxiety and sleep in childhood (between 7-11 years) and later suicidal ideation (SI; M = 3.3 years later). Sleep was assessed via subjective reports and objective measures (actigraphy and polysomnography). Children with greater anxiety symptoms were at greater risk for later SI when sleep disturbances were present in childhood. Results suggest that sleep disruption may amplify SI risk in anxious children.

Hyperglycaemia is an under-appreciated but modifiable risk factor in managing people with type 1 diabetes and fragility fractures

There are two major musculoskeletal effects of Type 1 diabetes mellitus (T1DM) - fragility fractures and impaired fracture union. Fractures in these patients are a significant and limb threatening injury. Traditionally, they have been treated with prolonged immobilisation and as rigid as possible internal fixation. Recently, hyperglycaemia has been recognised as the most significant modifiable risk factor in treating patients with T1DM and fractured limbs. This article reviews this association further and outlines the role of orthopaedic surgeons in minimising orthopaedic-related complications.

Unplanned Admission to the Intensive Care Unit in Postoperative Patients—An Indicator of Quality of Anaesthetic Care?

As a clinical indicator, unplanned admission to the Intensive Care Unit from the operating room has been thought to reflect the quality of anaesthesia care intraoperatively. To explore this concept, we examined all such admissions at three hospitals over a three-month period. Cases were classified according to the Victorian Consultative Council on Anaesthetic Mortality and Morbidity (VCCAMM) classification system and an assessment was made as to whether the admission was inevitable or not. Demographic data were collected as well as co-morbidities, severity of illness, length of stay, discharge functional status and destination.

There were 165 admissions identified: 55.8% were male, the median age was 63.5 years (range 15–90). There were 24 in-hospital deaths: 151 patients suffered serious morbidity or mortality. In 32 patients (19.4%), the morbidity or mortality was considered at least partially anaesthetic-related, and in 20 (12.1 %), under the control of the anaesthetist. There were 28 admissions (17.0%) with a further 9 anaesthetic-related admissions (5.5%) which were considered potentially avoidable. Avoidable anaesthetic-related admissions were due to drug overdosage (5 cases), drug error (1 case), problems relating to preoperative assessment (1 case), aspiration (1 case) and pulmonary oedema (1 case).

These findings suggest that unplanned admission to the Intensive Care Unit from the operating room is not a satisfactory indicator of quality of care by the anaesthesia team. This indicator appears to represent mainly the surgical and medical conditions of the patients, and their complications. Only one in twenty unplanned admissions in this series were potentially avoidable due to complications of the anaesthetic or the postoperative analgesia.

Consensus-based European guidelines for treatment of atopic eczema (atopic dermatitis) in adults and children: part II

This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This second part of the guideline covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions, whereas the first part covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy. Management of AE must consider the individual clinical variability of the disease. Systemic immunosuppressive treatment with cyclosporine, methotrexate, azathioprine and mycophenolic acid is established option for severe refractory cases, and widely available. Biologicals targeting the T helper 2 pathway such as dupilumab may be a safe and effective, disease-modifying alternative when available. Oral drugs such as JAK inhibitors and histamine 4 receptor antagonists are in development. Microbial colonization and superinfection may cause disease exacerbation and can require additional antimicrobial treatment. Allergen-specific immunotherapy with aeroallergens may be considered in selected cases. Psychosomatic counselling is recommended especially in stress-induced exacerbations. Therapeutic patient education ('Eczema school') is recommended for children and adult patients. General measures, basic emollient treatment, bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy have been addressed in the first part of the guideline.
