Remote hearings in family courts in England and Wales during Covid-19: Insights and lessons.

The introduction of social distancing measures during the COVID-19 pandemic resulted in family court hearings in England and Wales being conducted remotely, by video or telephone. Over a 15 months period, the Nuffield Family Justice Observatory undertook three rapid consultations to identify how remote proceedings were working, according to families and to a wide range of professionals who work in and around the family court. The consultations revealed the value of working remotely in certain circumstances, but also highlighted significant questions of fairness and justice.

Implementation of a Web-Based Organ Donation Educational Intervention: Development and Use of a Refined Process Evaluation Model.

Background: The lack of available organs is often considered to be the single greatest problem in transplantation today. Internet use is at an all-time high, creating an opportunity to increase public commitment to organ donation through the broad reach of Web-based behavioral interventions. Implementing Internet interventions, however, presents challenges including preventing fraudulent respondents and ensuring intervention uptake.

Seizure-related variables are predictive of attention and memory in children with epilepsy.

Children with epilepsy (CWE) are at greater risk for cognitive deficits and behavioral difficulties than are typically developing healthy children, and particular epileptic symptoms and treatments may contribute to this risk. The current study examined the relationships between four seizure-related variables and attention and memory functioning in a sample of 207 CWE (ages 6-16) using both neurocognitive and parent/teacher-report measures. Sociodemographic, medical, and neuropsychological data were collected from patients' medical charts in a retrospective fashion.

The Inclusion of African-American Study Participants in Web-Based Research Studies: Viewpoint.

The use of Web-based methods for research recruitment and intervention delivery has greatly increased as Internet usage continues to grow. These Internet-based strategies allow for researchers to quickly reach more people. African-Americans are underrepresented in health research studies.

Developing the Pediatric Refractory Epilepsy Questionnaire: a pilot study.

Purpose: Up to 14% of children with epilepsy continue to experience seizures despite having appropriate medical therapy and develop medically refractory epilepsy (MRE). Assessing clinical outcomes and therapeutic efficacy in children with MRE undergoing palliative epilepsy surgery has been challenging because of the lack of a quantitative instrument capable of estimating the clinical status of these patients. The ideal instrument would at once consider seizure control, neurodevelopment, caregiver burden, and quality of life.

Benign paroxysmal positional vertigo: concomitant involvement of different semicircular canals.

Objectives: We evaluated the simultaneous ipsilateral or contralateral involvement of the posterior and lateral, anterior and lateral, or posterior and anterior semicircular canals in patients with benign paroxysmal positional vertigo (BPPV).

Methods: The files of 2345 patients with BPPV were analyzed.

Results: Single-canal BPPV occurred in 2310 cases (98.

Neoadjuvant chemotherapy in invasive lobular carcinoma may not improve rates of breast conservation.

Background: Patients with invasive lobular carcinoma (ILC) experience a lower pathological complete response rate to neoadjuvant chemotherapy than patients with invasive ductal carcinoma. This study was intended to evaluate the impact of neoadjuvant chemotherapy in ILC on breast-conserving surgery (BCS) rates.

Methods: Two-hundred eighty-four consecutive patients with pure ILC treated between May 1998 and September 2006 were reviewed.

Penetrating thoracic trauma.

The initial approach to penetrating thoracic trauma is directed towards the pathophysiologic syndrome upon presentation. Most patients are successfully treated with drainage tubes. The unstable patient may necessitate thoracotomy at the emergency room to drain cardiac tamponade, provide cardiac massage and control bleeding.

Utility of ultrasound and fine-needle aspiration biopsy of the axilla in the assessment of invasive lobular carcinoma of the breast.

Background: The unique growth pattern of invasive lobular carcinoma (ILC) poses a challenge for preoperative assessment of disease extent within the breast. Whether it similarly limits lymph node staging by ultrasound (US) and fine-needle aspiration (FNA) biopsy was the subject of the current study.

Methods: A total of 217 patients with ILC who underwent axillary US were reviewed.

Impact of clinicopathological factors on sensitivity of axillary ultrasonography in the detection of axillary nodal metastases in patients with breast cancer.

Background: Ultrasonography and fine-needle aspiration (FNA) are used to evaluate the breast and regional nodes in breast cancer patients. We sought to identify factors influencing the sensitivity of ultrasonography for detection of nodal metastasis.

Methods: Patients with a clinically negative axilla who underwent axillary ultrasonography and sentinel lymph node biopsy were included.

Reduction of pain episodes and prothrombotic activity in sickle cell disease by dietary n-3 fatty acids.

The effects of dietary n-3 fatty acids (n-3FAs) on the frequency of pain episodes and ex vivo blood tests of thrombosis have been evaluated in patients with sickle cell disease (SCD) utilizing a double-blind, olive oil-controlled clinical trial. Dietary n-3FA therapy (0.1 g/kg/d) was provided as menhaden fish oil (0.

Beta-cell function and visceral fat in lactating women with a history of gestational diabetes.

Lactation has been recommended as beneficial for the maternal metabolic abnormalities associated with glucose intolerance and diabetes risk, although associations between breastfeeding (BF), glucose tolerance, and adipose tissue distribution are unknown. Therefore, a population of women with recent gestational diabetes (GDM) was evaluated with comparison of results for lactating versus nonlactating women. A total of 26 women participated (14 BF and 12 nonbreastfeeding [nonBF]) with a singleton vaginal delivery after 36 weeks gestation.

Thrombogenesis in sickle cell disease.

Thirty-three subjects with sickle cell disease (SCD), 11 during episodes of pain and 22 during periods without pain, were evaluated for in vivo thrombogenic activities as compared with 10 normal black control subjects. Measurements were performed for (1) platelet surface activation, assessing flow cytometric expression of activated integrin alpha(IIb)beta(3) receptor (GPIIb/IIIa, CD41a) and P-selectin (CD62p); (2) platelet and erythrocyte surface procoagulant activities, measuring flow cytometric binding of activated factor (FVa) and annexin V; (3) plasma levels of platelet-specific secreted proteins platelet factor 4 (PF4) and beta-thromboglobulin (betaTG); (4) plasma markers of thrombin generation, prothrombin activation fragment (F(1.2)), and thrombin: antithrombin complex (TAT); and (5) plasma markers of fibrinolysis, D -dimer, and plasmin:antiplasmin complex (PAP).

The sensitivity of indicators of thrombosis initiation to a bileaflet prosthesis leakage stimulus.

Background And Aim Of The Study: The recent clinical history and experimental studies of the Medtronic Parallel (MP) valve suggest that bileaflet valve leakage flow is a primary initiator of thrombosis. These studies investigated the effects of physiologic leakage flow through a MP valve on various markers of blood damage.

Methods: A centrifugal pump was used to drive whole, human blood anticoagulated with PPACK through a circuit containing a MP 27 mm valve in the closed position (experimental runs) or a MP 27 mm valve in the open position (control runs).

Expressions of positive emotion in women's college yearbook pictures and their relationship to personality and life outcomes across adulthood.

To test hypotheses about positive emotion, the authors examined the relationship of positive emotional expression in women's college pictures to personality, observer ratings, and life outcomes. Consistent with the notion that positive emotions help build personal resources, positive emotional expression correlated with the self-reported personality traits of affiliation, competence, and low negative emotionality across adulthood and predicted changes in competence and negative emotionality. Observers rated women displaying more positive emotion more favorably on several personality dimensions and expected interactions with them to be more rewarding; thus, demonstrating the beneficial social consequences of positive emotions.

Effects of megakaryocyte growth and development factor on platelet production, platelet life span, and platelet function in healthy human volunteers.

The effects of thrombopoietic stimulation on megakaryocytopoiesis, platelet production, and platelet viability and function were examined in normal volunteers randomized to receive single bolus subcutaneous injections of 3 microg/kg pegylated recombinant megakaryocyte growth and development factor (PEG-rHuMGDF) or placebo in a 3:1 ratio. PEG-rHuMGDF transiently doubled circulating platelet counts, from 237 +/- 41 x 10(3)/microL to 522 +/- 90 x 10(3)/microL (P <.0001), peaking on day 12.

Effects of Mpl ligands on platelet production and function in nonhuman primates.

Endogenous thrombopoietin (TPO) stimulates platelet production in nonhuman primates dose-dependentbyinducing megakaryocyte development from early marrow hematopoietic progenitors and subsequent proliferation and endoreduplication. Recombinant human TPO, nonpegylated or pegylated recombinant human megakaryocyte growth and development factor produce log-linear responses in peak peripheral platelet counts (or peripheral platelet mass turnover), platelet TPO receptor density, and marrow megakaryocyte volume, ploidy, number and mass. Mpl ligand therapy sustains normal peripheral platelet concentrations following myelosuppressive chemotherapy in baboons and corrects peripheral platelet counts in HIV-infected chimpanzees with severe thrombocytopenia.

Reduction in vascular lesion formation by hirudin secreted from retrovirus-transduced confluent endothelial cells on vascular grafts in baboons.

Background: The hypothesis that thrombin mediates the formation of neointimal vascular lesions at sites of mechanical vascular injury has been tested in baboons by measurement of the effects of hirudin delivered by retrovirus-transduced hirudin-secreting vascular endothelial cells (ECs) lining surgically implanted arterial vascular grafts (AVGs).

Methods And Results: The antithrombotic efficacy of baboon ECs transduced with cDNA encoding hirudin was assessed in vitro and in vivo on thrombogenic segments in chronically exteriorized femoral arteriovenous (AV) shunts. Bilateral brachial AVGs lined with hirudin-transduced versus nonhirudin control ECs at confluent density were surgically implanted, and vascular lesion formations at distal graft-vessel anastomoses were compared after 30 days.

Comparative safety and tolerability of clopidogrel and aspirin: results from CAPRIE. CAPRIE Steering Committee and Investigators. Clopidogrel versus aspirin in patients at risk of ischaemic events.

Objective: The objective of this study was to provide a comprehensive comparison of the long term safety and tolerability of clopidogrel, a new adenosine diphosphate (ADP) receptor antagonist that inhibits platelet activation induced by ADP, and aspirin (acetylsalicylic acid).

Patients And Methods: The study population comprised 19,185 patients with symptomatic atherosclerosis manifested as recent ischaemic stroke, recent myocardial infarction or symptomatic peripheral arterial disease. Patients were randomised to receive clopidogrel 75 mg/day or aspirin 325 mg/day for a minimum of 1 year and a maximum of 3 years.

The progression of thrombus in an ex-vivo shunt model evaluated by intravascular ultrasound radiofrequency analysis.

We tested the ability of ultrasound radiofrequency (RF) signal analysis to characterize thrombus accumulation in a Dacron graft incorporated into the exteriorized arteriovenous shunt in 3 baboons with constant blood flow for 60 min. Thrombus formation was quantified by sequential measurements of 111Indium-labeled platelet deposition. RF signals were acquired every 15 min at 2 sites in the graft, using a 2.

Prophylactic angioplasty reduces thrombosis in virgin ePTFE arteriovenous dialysis grafts with greater than 50% stenosis: subset analysis of a prospectively randomized study.

Purpose: To determine if prophylactic percutaneous transluminal balloon angioplasty (PTA) can extend patency in functioning virgin ePTFE arteriovenous hemodialysis grafts.

Materials And Methods: The results of a prospectively randomized study of 64 patients with greater than 50% stenosis of functioning ePTFE arteriovenous hemodialysis grafts who were blindly assigned to be treated with PTA (treatment group) or observed without treatment (control group) were subjected to statistical subset analysis. Within this group were 21 patients (virgins) who had never undergone surgery, PTA, or thrombolysis.

Physiology and clinical applications of platelet growth factors.

Recombinant human thrombopoietin, or pegylated recombinant human megakaryocyte growth and development factor, produces log-linear increases in megakaryocytopiesis and platelet production. Recent clinical studies investigating the efficacy, safety, and cost benefit of administering platelet growth factors indicate that appropriate dosing of pegylated recombinant human megakaryocyte growth and development factor, or recombinant human thrombopoietin, during chemotherapeutic marrow suppression produces these increases in four ways. First, these factors improve ensuant thrombocytopenia without producing platelet-dependent thrombo-occlusive complications.

Multichannel cochlear implantation in children with large vestibular aqueduct syndrome.

This study examined the postoperative performance of multichannel cochlear implantation in children with severe-to-profound sensorineural hearing loss secondary to large vestibular aqueduct syndrome. Five children between ages 4 and 13 years who had large vestibular aqueducts confirmed by computed tomography scans underwent implantation of a CLARION Multi-Strategy Cochlear Implant between January 1995 and June 1996 at Boys Town National Research Hospital. In addition to preoperative evaluations, they were examined postoperatively with their implants on a battery of open-set speech recognition tests at 3, 6, 12, and 18 months following initial stimulation.

Implantation of the CLARION cochlear implant in an ossified cochlea.

This report describes the successful implantation of the CLARION Multi-Strategy Cochlear Implant electrode in the totally ossified cochlea of a 5-year-old child via a radical mastoidectomy approach. Postoperatively, the child demonstrated responses to auditory stimuli, even though the electrode array contacted only bone and muscle graft tissue with no visible evidence of nerve fibers or cochlear lumen. Responses to sound did not begin to emerge until 10 weeks following initial stimulation and improved slowly over time.
