Patients' satisfaction with fast‐track surgery in gynaecological oncology

This study investigates the experience and satisfaction with care of fast‐tracked gynaecological patients. The Sydney Gynaecological Oncology Group, New South Wales, Australia, has previously shown the benefits of a fast‐track surgery programme for gynaecology patients with both complex benign gynaecological pathology and gynaecological malignancy. The question of whether these benefits translate into a positive experience for fast‐tracked patients, in the context of their hospital stay and healthcare team care, has not been previously explored in detail. A self‐administered satisfaction questionnaire incorporating the European Organisation for Research and Treatment of Cancer (EORTC) cancer in‐patient satisfaction with care measure (INPATSAT‐32) questionnaire with additional questions was administered to 106 gynaecology participants at Royal Prince Alfred Hospital. Participants reported high levels of satisfaction with patient care and support received from doctors, ward nurses and the hospital as a service and care organisation, within the context of a fast‐track surgical programme. Early hospital discharge after gynaecological surgery results in both enhanced recovery after surgery (ERAS) and high levels of patient satisfaction.     

Student reflective groups at a Scottish College of Nursing

In this paper student views on reflective groups, set up as an important element of the new Project 2000 course in a Scottish College of Nursing, are reported. A random sample of 19 students were interviewed. While the reflective groups were very popular with students because they provided support, there was little evidence of a linkage between theory and practice. It was clear that the ambitious objective of stimulating reflection-on-action was not attained. Practice certainly was discussed, but it tended to be dominated by dramatic and emotionally charged aspects of care rather than the more frequent routine concerns. There were, however, indications that the original aim of the reflective groups could be achieved if tutors could establish a common understanding of the purpose of the groups and of reflection, and if the practices on which students reflected consisted less of single day visits where the students saw themselves as non-participant outsiders.     

Childhood chronic inflammatory demyelinating polyradiculoneuropathy: Combined analysis of a large cohort and eleven published series

The clinical presentation, disease course, response to treatment, and long-term outcome of thirty childhood chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) patients are presented representing the largest cohort reported to date. Most children (60%) presented with chronic (>8-weeks) symptom-onset while a smaller proportion showed sub-acute (4–8 weeks) or acute (‘‘GBS-like’’; <4 weeks) onset of disease. No gender predilection was observed. The majority of patients had a relapsing (70%) versus a monophasic (30%) temporal profile. Most received initial IVIG monotherapy; 80% showing a good response. Long-term follow-up (mean = 3.8 years) was available for 23 patients; 45% were off all immunomodulatory medications, demonstrating no detectable (55%) or minimal (43%) clinical deficits. Our data were compared with 11 previously published childhood CIDP series providing a comprehensive review of 143 childhood CIDP cases. The combined initial or first-line treatment response across all studies was favourable for IVIG (79% patients) and corticosteroids (84% patients). Response to first-line plasma exchange was poor (only 14% patients improved) although it may offer some transient or partial benefit as an adjuvant or temporary therapy for selected patients. The combined long-term outcome of our cohort and the literature reveals a favourable prognosis for most patients. The combined modified Rankin scale decreased from 3.7 (at presentation) to 0.7 (at last follow-up). This review provides important data pertaining to clinical course, treatment response and long-term outcome of this relatively uncommon paediatric autoimmune disease.     

Evaluation of collateral circulation of the hand

In 1929, Edgar V. Allen described a noninvasive evaluation of the patency of the arterial supply to the hand of patients with thromboangitis obliterans (Am J Med Sci 1929;178:237). In the early 1950s, Allen's test was modified (Wright I. Vascular diseases in clinical practice. Chicago: Year Book Medical Publishers, 1952) for use as a test of collateral circulation prior to arterial cannulation. This test involves the examiner occluding the patient's ulnar and radial arteries while the patient makes a fist, causing the hand to blanch. The patient is then asked to extend the fingers. After the hand is open, the examiner releases the ulnar artery while continuing to maintain pressure on the radial artery. Adequate collateral circulation is felt to be indicated by return of normal color to the hand. The patient is instructed not to hyperextend the fingers when opening the hand. Hyperextension may cause a decrease in perfusion to the arch, possibly resulting in a false interpretation of the Allen test (Anesthesiology 1972;37:356). The modified Allen's test can be performed quickly and easily, but it is susceptible to error. (With Allen's original test, both hands were tested simultaneously. The patient clenched both fists tightly for 1 minute while the examiner compressed one artery of each hand. This method helps diagnose complete occlusion, just as Allen intended. The test was later modified, however, to evaluate the adequacy of collateral circulation. To perform the modified Allen's test, the examiner compresses both arteries while the patient's fists are clenched. The patient then opens the hand, and the adequacy of circulation is evaluated when the examiner releases one of the arteries.) This study was designed to combine the modified Allen's test with the sensitivity of oximetry and plethysmography to provide a quantifiable and reproducible evaluation of the palmar collateral circulation with or without the subject's cooperation. Superficial palmar arches of 90 normal volunteers (aged 22–45 years) were evaluated with the modified Allen's test. These results were compared with the flow patterns demonstrated by plethysmography and pulse oximetry. All of the modified Allen's tests were normal, with the palmar blush occurring in an average of 2.3 seconds (range, 2–5 s). Results were recorded independently by two observers, with agreement in all cases. Four of the 90 (4.4%) palmar arches were found to have abnormal circulatory patterns. Plethysmography clearly demonstrated the dominant arterial supply to the hand and, in appropriate cases, indicated the existence of an incomplete arch. The four abnormal circulatory patterns (two incomplete palmar arches and two other aberrant arterial communications) were clearly shown by plethysmography. Pulse oximetry was found to be too sensitive. Significant changes in flow did not result in a decrease in saturation. Only the incomplete superficial palmar arches resulted in a change in saturation. The two abnormal arterial communications were not detected by pulse oximetry. Pulse oximetry also could not show dominant flow patterns. Our findings indicate that plethysmography can be used to demonstrate palmar collateral circulation, but that pulse oximetry cannot.This work was funded by the Anesthesiology Research Foundation and the Samuel J. Roessler Research Scholarship.This paper was presented at the Society of Critical Care Medicine's 19th Annual Education and Scientific Symposium, San Francisco, California, May, 1990.     

Co-Deletion of A238L and EP402R Genes from a Genotype IX African Swine Fever Virus Results in Partial Attenuation and Protection in Swine

African swine fever virus (ASFV) is the causative agent of African swine fever (ASF), resulting in up to 100% mortality in pigs. Although endemic in most sub-Saharan African countries, where all known ASFV genotypes have been reported, the disease has caused pandemics of significant economic impact in Eurasia, and no vaccines or therapeutics are available to date. In endeavors to develop live-attenuated vaccines against ASF, deletions of several of the ~170 ASFV genes have shown contrasting results depending on the genotype of the investigated ASFV. Here, we report the in vivo outcome of a single deletion of the A238L (5EL) gene and double deletions of A238L (5EL) and EP402R (CD2v) genes from the genome of a highly virulent genotype IX ASFV isolate. Domestic pigs were intramuscularly inoculated with (i) ASFV-Ke-ΔA238L to assess the safety of A238L deletion and (ii) ASFV-Ke-ΔEP402RΔA238L to investigate protection against challenge with the virulent wildtype ASFV-Ke virus. While A238L (5EL) gene deletion did not yield complete attenuation, co-deletion of A238L (5EL) and EP402R (CD2v) improved the safety profile of the single deletions, eliciting both humoral and cellular immune responses and conferred partial protection against challenge with the virulent wildtype ASFV-Ke virus.     

Genetic and genomic analysis of acute lymphoblastic leukemia in older adults reveals a distinct profile of abnormalities: analysis of 210 patients from the UKALL14 and UKALL60+ clinical trials

Despite being predominantly a childhood disease, the incidence of acute lymphoblastic leukemia (ALL) has a second peak in adults aged 60 years and over. These older adults fare extremely poorly with existing treatment strategies and very few studies have undertaken a comprehensive genetic and genomic characterization to improve prognosis in this age group. We performed cytogenetic, single nucleotide polymorphism (SNP) array and next-generation sequencing (NGS) analyses on samples from 210 patients aged ≥60 years from the UKALL14 and UKALL60+ clinical trials. BCR-ABL1-positive disease was present in 26% (55/210) of patients, followed by low hypodiploidy/near triploidy in 13% (28/210). Cytogenetically cryptic rearrangements in CRLF2, ZNF384 and MEF2D were detected in 5%, 1% and <1% of patients, respectively. Copy number abnormalities were common and deletions in ALL driver genes were seen in 77% of cases. IKZF1 deletion was present in 51% (40/78) of samples tested and the IKZF1^plus profile was identified in over a third (28/77) of cases of B-cell precursor ALL. The genetic good-risk abnormalities high hyperdiploidy (n=2), ETV6-RUNX1 (no cases) and ERG deletion (no cases) were exceptionally rare in this cohort. RAS pathway mutations were seen in 17% (4/23) of screened samples. KDM6A abnormalities, including biallelic deletions, were discovered in 5% (4/78) of SNP arrays and 9% (2/23) of NGS samples, and represent novel, potentially therapeutically actionable lesions using EZH2 inhibitors. Outcome remained poor with 5-year event-free and overall survival rates of 17% and 24%, respectively, across the cohort, indicating a need for novel therapeutic strategies.
