ABSTRACT

INTRODUCTION: Long-acting injectable cabotegravir + rilpivirine (CAB + RPV LAI) was approved for use in virally suppressed adults in the England and Wales national health service in November 2021. We describe a service evaluation of delivery processes and outcomes in 12 clinics. METHODS: Centres populated a database using information from local policies and clinical records. Services were asked to describe approval processes, clinic pathways, and adherence to national guidelines. Additional data were collected on reasons for regimen choice, treatment discontinuations, and management of viraemia. RESULTS: In total, 518 adults from 12 clinics were approved for CAB + RPV LAI between February 2022 and December 2023. Of the 518 people approved for CAB + RPV LAI, 423 received at least one injection. Median duration on CAB + RPV was 7.5 months (interquartile range 3.7-11.3). In total, 97% of injections were administered within the ±7-day window. Virological failure occurred in 0.7%, and 6% discontinued CAB + RPV. CONCLUSION: In this large UK-based cohort, robust approval processes and clinic protocols facilitated on-time injections and low rates of both discontinuation and virological failure.

ABSTRACT

Current therapies for myeloproliferative neoplasms (MPNs) improve symptoms but have limited effect on tumor size. In preclinical studies, tamoxifen restored normal apoptosis in mutated hematopoietic stem/progenitor cells (HSPCs). TAMARIN Phase-II, multicenter, single-arm clinical trial assessed tamoxifen's safety and activity in patients with stable MPNs, no prior thrombotic events and mutated JAK2V617F, CALRins5 or CALRdel52 peripheral blood allele burden ≥20% (EudraCT 2015-005497-38). 38 patients were recruited over 112w and 32 completed 24w-treatment. The study's A'herns success criteria were met as the primary outcome ( ≥ 50% reduction in mutant allele burden at 24w) was observed in 3/38 patients. Secondary outcomes included ≥25% reduction at 24w (5/38), ≥50% reduction at 12w (0/38), thrombotic events (2/38), toxicities, hematological response, proportion of patients in each IWG-MRT response category and ELN response criteria. As exploratory outcomes, baseline analysis of HSPC transcriptome segregates responders and non-responders, suggesting a predictive signature. In responder HSPCs, longitudinal analysis shows high baseline expression of JAK-STAT signaling and oxidative phosphorylation genes, which are downregulated by tamoxifen. We further demonstrate in preclinical studies that in JAK2V617F+ cells, 4-hydroxytamoxifen inhibits mitochondrial complex-I, activates integrated stress response and decreases pathogenic JAK2-signaling. These results warrant further investigation of tamoxifen in MPN, with careful consideration of thrombotic risk.

ABSTRACT

PURPOSE: Polycythemia vera (PV) is characterized by JAK/STAT activation, thrombotic/hemorrhagic events, systemic symptoms, and disease transformation. In high-risk PV, ruxolitinib controls blood counts and improves symptoms. PATIENTS AND METHODS: MAJIC-PV is a randomized phase II trial of ruxolitinib versus best available therapy (BAT) in patients resistant/intolerant to hydroxycarbamide (HC-INT/RES). Primary outcome was complete response (CR) within 1 year. Secondary outcomes included duration of response, event-free survival (EFS), symptom, and molecular response. RESULTS: One hundred eighty patients were randomly assigned. CR was achieved in 40 (43%) patients on ruxolitinib versus 23 (26%) on BAT (odds ratio, 2.12; 90% CI, 1.25 to 3.60; P = .02). Duration of CR was superior for ruxolitinib (hazard ratio [HR], 0.38; 95% CI, 0.24 to 0.61; P < .001). Symptom responses were better with ruxolitinib and durable. EFS (major thrombosis, hemorrhage, transformation, and death) was superior for patients attaining CR within 1 year (HR, 0.41; 95% CI, 0.21 to 0.78; P = .01); and those on ruxolitinib (HR, 0.58; 95% CI, 0.35 to 0.94; P = .03). Serial analysis of JAK2V617F variant allele fraction revealed molecular response was more frequent with ruxolitinib and was associated with improved outcomes (progression-free survival [PFS] P = .001, EFS P = .001, overall survival P = .01) and clearance of JAK2V617F stem/progenitor cells. ASXL1 mutations predicted for adverse EFS (HR, 3.02; 95% CI, 1.47 to 6.17; P = .003). The safety profile of ruxolitinib was as previously reported. CONCLUSION: The MAJIC-PV study demonstrates ruxolitinib treatment benefits HC-INT/RES PV patients with superior CR, and EFS as well as molecular response; importantly also demonstrating for the first time, to our knowledge, that molecular response is linked to EFS, PFS, and OS.

ABSTRACT

Patients who undergo solid organ transplantation are at risk of opportunistic infection associated with immunosuppression. We report a case of confirmed donor derived visceral leishmaniasis (VL), in a patient following liver transplantation causing fever and pancytopenia. The diagnosis was confirmed by bone marrow biopsy, with confirmed positive donor serology, with no other route of transmission. To our knowledge, this is the first case report in the United Kingdom and Europe, of confirmed organ donor transmission of VL. This case report highlights an important consideration of donor derived infections, in the context of solid organ transplantation.

ABSTRACT

BACKGROUND: The World Health Organization have designed the fifth of their '5 moments' for hand hygiene to account for microbial transfer from patients to equipment in a narrow area around that patient, known as the patient zone. The study was prompted by emerging local confusion about application of the patient zone in the operating room (OR). AIM/OBJECTIVES: In two phases, we aimed to create a '5 moments' style poster displaying an OR patient zone: phase 1, quantify equipment, in direct contact with the patient and, touched by non-scrubbed staff immediately after touching the patient; and phase 2, categorise equipment identified in phase 1 into patient zone and healthcare zone. An objective is to produce a '5 moments' poster for the OR. METHODS: The first phase used non-participant direct overt observation. In phase 2, phase 1 data were collaboratively assigned to patient zone or healthcare zone. Photography and graphic design were used to produce the OR '5 moments' poster. RESULTS: In 11 full-length surgeries, 20 pieces of equipment were in direct contact with the patient and 57 pieces of equipment were touched. In phase 2, a '5 moments' poster showing an OR patient zone was designed. DISCUSSION: Content of the patient zone was identified and displayed in a novel resource. Having shared understanding of the patient zone has potential to sustain hand hygiene compliance and equipment cleaning in the OR. CONCLUSION: Limitations in methods were balanced by collaboration with frontline staff. The study has been used as a teaching tool in the OR and similar settings.

ABSTRACT

We previously reported the safety and efficacy of low dose BaP [Bezafibrate (Bez) and Medroxyprogesterone acetate (MPA)] in 20 acute myeloid leukaemia (AML) patients for whom chemotherapy was not an option. This study provided evidence that BaP had anti-AML activity and improved haemopoiesis; absence of haematological toxicity allowed continuous daily administration. Similarly a previous trial in endemic Burkitt lymphoma demonstrated anti-B cell lymphoma activity of low and high dose BaP again in the absence of toxicity. We conducted a study to further evaluate the safety and activity of high dose BaP therapy in adults with AML (and high risk Myelodysplastic Syndromes (MDS)), chronic lymphocytic leukaemia (CLL) or B-cell Non-Hodgkin Lymphoma (BHNL). Eighteen patients were recruited to the study over 20 months, 16 AML/MDS, 1 CLL, and 1 BNHL. Although MPA was well tolerated throughout the study, only 2 patients were able to tolerate Bez treatment for their whole trial duration, indicating that Bez escalation is not feasible in the setting of adult AML/MDS. Thus there has been no obvious benefit in improved haemopoiesis or overt anti-leukaemia activity from the attempts to escalate BaP dose over previous published studies. Since current therapeutic options in MDS are restricted it may be now of value to continue to evaluate low dose BaP based approaches in low risk MDS rather than AML/high risk MDS. Furthermore, screening of low dose BaP against libraries of other already available dugs may identify an addition to BaP that augments the anti-neoplastic efficacy without significant toxicity.

ABSTRACT

BACKGROUND: Pharmacist prescribing has been introduced in several countries and is a possible future role for pharmacy in Australia. OBJECTIVE: To assess whether patient satisfaction with the pharmacist as a prescriber, and patient experiences in two settings of collaborative doctor-pharmacist prescribing may be barriers to implementation of pharmacist prescribing. DESIGN: Surveys containing closed questions, and Likert scale responses, were completed in both settings to investigate patient satisfaction after each consultation. A further survey investigating attitudes towards pharmacist prescribing, after multiple consultations, was completed in the sexual health clinic. SETTING AND PARTICIPANTS: A surgical pre-admission clinic (PAC) in a tertiary hospital and an outpatient sexual health clinic at a university hospital. Two hundred patients scheduled for elective surgery, and 17 patients diagnosed with HIV infection, respectively, recruited to the pharmacist prescribing arm of two collaborative doctor-pharmacist prescribing studies. RESULTS: Consultation satisfaction response rates in PAC and the sexual health clinic were 182/200 (91%) and 29/34 (85%), respectively. In the sexual health clinic, the attitudes towards pharmacist prescribing survey response rate were 14/17 (82%). Consultation satisfaction was high in both studies, most patients (98% and 97%, respectively) agreed they were satisfied with the consultation. In the sexual health clinic, all patients (14/14) agreed that they trusted the pharmacist's ability to prescribe, care was as good as usual care, and they would recommend seeing a pharmacist prescriber to friends. DISCUSSION AND CONCLUSION: Most of the patients had a high satisfaction with pharmacist prescriber consultations, and a positive outlook on the collaborative model of care in the sexual health clinic.

ABSTRACT

OBJECTIVE: Our study aimed to develop a survey that could be used by nurses during regular cystic fibrosis (CF) clinic visits, providing clinicians with a standardized means of longitudinally assessing and monitoring symptom progression in their patients. In addition, the use of this survey would provide an opportunity for patient engagement and relationship building, thereby enhancing patient education and improving adherence to treatment. This is the first such survey designed specifically for use in Arab populations. . METHODS: The Cystic Fibrosis Symptom Progression Survey (CF-SPS) was developed using previously published patient reported outcomes relating to pulmonary exacerbations in CF. It contains 10 items that provide a patient-focused account of symptoms. The survey was translated into Arabic and was completed by 12 patients on 139 occasions over 22 months. The psychometric properties of the survey were evaluated, as was the relationship between the survey findings and other known clinical measures of health status in CF. . RESULTS: The CF-SPS performs well as a psychometrically valid clinical tool, with good internal consistency as determined by Cronbach's alpha analysis. Our results suggest that the CF-SPS is able to identify significant declines in health status in line with routine clinical patient assessment (chest sounds, body mass index and admissions). As such it is a useful tool that can support clinical decision making in the care of Arabic speaking CF patients. . CONCLUSION: We recommend the CF-SPSa (Arabic version) as a valid tool for the longitudinal monitoring of symptom progression in CF in Arabic speaking populations.

ABSTRACT

OBJECTIVES: Cystic fibrosis transmembrane conductance regulator (CFTR) mutations form distinct mutational panels in different populations and subgroups. The frequency of cystic fibrosis (CF) mutations and prevalence are unknown in Oman. This study aimed to elucidate the mutational panel and prevalence of CF for the North Al Batinah (NAB) region in Oman and to estimate the national prevalence of CF based on the carrier screening of unrelated volunteers. METHODS: The study included retrospective and prospective analyses of CF cases in the NAB region for 1998-2012. Genetic analysis of disease-causing mutations was conducted by screening of the entire coding sequence and exon-intron borders. The obtained mutational panel was used for the carrier screening of 408 alleles of unrelated and unaffected Omani individuals. RESULTS: S549R and F508del were the major mutations, accounting for 89% of mutations in the patient population. Two private mutations, c.1733-1734delTA and c.1175T>G, were identified in the patient cohort. Two carriers, one for F508del and another for S549R, were identified by screening of the volunteer cohort, resulting in a predicted prevalence for Oman of 1 in 8,264. The estimated carrier frequency of CF in Oman was 1 in 94. The carrier frequency in the NAB region was 3.9 times higher. CONCLUSION: The mutational panel for the NAB region and the high proportion of S549R mutations emphasises the need for specific screening for CF in Oman. The different distribution of allele frequencies suggests a spatial clustering of CF in the NAB region.

ABSTRACT

This study analyses the narrative elements of a little-known report into anti-venereal trials written by an Irish military physician-surgeon, Daniel O'Sullivan (1760-c.1797). It explores the way in which O'Sullivan as the narrator of the Historico-critical report creates medical heroes and anti-heroes as a means to criticise procedures initiated by staff in the Hospital General de San Andrés, Mexico City. The resulting work depicts a much less positive picture of medical trials and hospital authorities in this period than has been recorded to date, and provides a critical and complicated assessment of one of Spain's leading physicians of the nineteenth century, Francisco Javier Balmis (1753-1819).
