Background Data on the cost effectiveness of hepatitis B virus (HBV) screening and vaccination strategies for prevention of vertical transmission of HBV in resource limited settings is sparse. Methods A decision tree model of HBV prevention strategies utilised data from a cohort of 7071 pregnant women on the Thailand-Myanmar border using a provider perspective. All options included universal HBV vaccination for newborns in three strategies: (1) universal vaccination alone; (2) universal vaccination with screening of women during antenatal visits with rapid diagnostic test (RDT) plus HBV immune globulin (HBIG) administration to newborns of HBV surface antigen positive women; and (3) universal vaccination with screening of women during antenatal visits plus HBIG administration to newborns of women testing HBV e antigen positive by confirmatory test. At the time of the study, the HBIG after confirmatory test strategy was used. The costs in United States Dollars (US$), infections averted and incremental cost effectiveness ratios (ICERs) were calculated and sensitivity analyses were conducted. A willingness to pay threshold of US$1200 was used. Results The universal HBV vaccination was the least costly option at US$4.33 per woman attending the clinic. The HBIG after (RDT) strategy had an ICER of US$716.78 per infection averted. The HBIG after confirmatory test strategy was not cost-effective due to extended dominance. The one-way sensitivity analysis showed that while the transmission parameters and cost of HBIG had the biggest impact on outcomes, the HBIG after confirmatory test only became a cost-effective option when a low test cost was used or a high HBIG cost was used. The probabilistic sensitivity analysis showed that HBIG after RDT had an 87% likelihood of being cost-effective as compared to vaccination only at a willingness to pay threshold of US$1200. Conclusions HBIG following confirmatory test is not a cost-effective strategy for preventing vertical transmission of HBV in the Thailand-Myanmar border population. By switching to HBIG following rapid diagnostic test, perinatal infections will be reduced by nearly one third. This strategy may be applicable to similar settings for marginalized populations where the confirmatory test is not logistically possible.

Introduction: Infection from Hepatitis B primarily results from peri-partum vertical transmission and the risk increases in the presence of hepatitis B e antigen. We aimed to evaluate a new screening program for hepatitis B in pregnant women as a component of antenatal services in a marginalized population. Methodology: Counseling and screening for hepatitis B screening was offered to all women at the first visit, at Shoklo Malaria Research Unit (SMRU) antenatal clinics on the Thai-Myanmar border.  Point-of-care rapid diagnostic tests (RDT) were used throughout the period of evaluation. A certified Thai Public Health laboratory at Mae Sot Hospital verified RDT positive cases using enzyme-linked immunosorbent assay (ELISA) for HBsAb and HBeAg. Risk factors for hepatitis B were identified by data linkage to antenatal care records. Results: There were 523 (8.5%) RDT positive for HBsAg among 6158 women tested (Aug-2012 to April-2014). Of these 373 (96.9%) of 385 sent for confirmation were positive by ELISA i.e. RDT false positive rate of 3.1% (95% CI 1.7- 5.4). The overall confirmed HbsAg prevalence was 8.3% (511/6158) (95%CI 7.6-9.0). HBeAg prevalence was 32.7% (114/350) (95%CI 27.9-37.7) of cases tested. Risk factors for HBsAg positivity included age >25 years (OR 1.24, CI 1.03-1.49, p 0.021) and Karen heritage (OR 1.73, CI 1.39-2.15, p < 0.01). Conclusions: High hepatitis B seroprevalence amongst migrants and refugees accessing SMRU antenatal services likely reflects that of Kayin State, Myanmar, and perinatal prevention programs are required. False positive cases with HBsAg RDT complicate what is theoretically a straightforward screening.

The COVID-19 pandemic has forced reorganization of clinical services to minimize face-to-face contact between patients and health-care providers. Specialist services, including clinical genetics, must consider methods of remote delivery including videoconferencing—termed telegenetics. This review evaluates the evidence for telegenetics and its applicability to future service development. A systematic review of six databases was conducted to identify studies from 2005 onward using synchronous videoconferencing to deliver clinical genetics services. Included studies compared telegenetics to an alternative method or used a before and after design. Thirteen studies met the inclusion criteria (eight compared telegenetics to in-person consultations and three to telephone delivery). Patient satisfaction, genetic knowledge, and psychosocial outcomes were similar for in-person and telegenetic counseling. There was some evidence that telegenetics may be superior to telephone delivery for knowledge gain and reduction in anxiety and depression. There is limited evidence concerning the effect of telegenetics on provider satisfaction and behavioral outcomes. Conclusions are limited by at least moderate risk of bias in all evaluated studies and small sample sizes. Across most outcomes measured, telegenetics had equivalent outcomes to in-person appointment; however, the extent to which the available evidence is applicable to longer-term use is debatable.

Background: The advent of immunotherapy has revolutionised cancer treatment by harnessing the immune system to target tumour cells. However, there is increasing awareness of immunotherapy-related adverse events, which can be severe and even fatal. While system-specific immune-related adverse events (ir-AEs) are well documented, growing evidence suggests the existence of overlap syndromes—distinct clusters of immune-mediated complications. One such syndrome is the overlap of myasthenia gravis, myositis and myocarditis, collectively known as Triple M (3M) syndrome. This syndrome is complex, varying in presentation and severity, with in-hospital mortality rates approaching 40%. Whilst there is consensus on the management of system-specific complications, there is no consensus guidance for the management of these overlap syndromes. Methods: In this paper, we conduct a review of the literature, analysing reported cases of 3M syndrome, focusing on treatment approaches and patient outcomes at an individual level. Conclusions: This review highlights the complexity of diagnosing and managing 3M syndrome due to inconsistent reporting, lack of standardised criteria for diagnosis, and treatment variability. While evidence remains limited, we offer broad clinical recommendations and underscore the urgent need for consensus definitions, prospective data collection, and structured treatment guidance.

Background:Prostate cancer is a common malignancy with rising incidence in Western countries such as the United Kingdom. In localised disease there are a variety of curative treatment modalities. Patients can be referred for surgery, or for a combination of hormonal therapies and radiotherapy (external beam radiotherapy or brachytherapy). Each treatment option comes with side effects and in the case of radiotherapy one potential complication is bowel toxicity from radiation exposure. New technologies are being developed to try and mitigate the side effects and long term morbidity of this treatment, and to expand access to radiotherapy for patients who may previously have been excluded (i.e those with inflammatory bowel disease). Rectal Spacers are absorbable polyethylene glycol hydrogels injected into the perirectal space. These position the anterior rectal wall away from the prostate, subsequently minimising radiation dose to the rectum. Rectal Spacers have been introduced to National Healthcare Service (NHS) practice as part of the Innovation and Technology Payment (ITP) programme, however, their use is now under review.Methodology and Results:In this editorial we conduct a narrative review of some of the available evidence for Rectal Spacers, discuss their utilization within the NHS and the barriers to their wider use. We also explore preliminary dosimetry and quality of life data for use of Rectal Spacers in our centre where we have been part of the NHS ITP programme. Dosimetry data and Quality of life questionnaires were gathered from 22 treated patients and 11 matched controls. This indicated lower radiation doses to the prostate in those treated with Rectal Spacers.Conclusion:Rectal Spacers are an effective method to reduce radiation dose to the prostate in men treated for localised prostate cancer, however, their use remains under review in the NHS and there are a variety of barriers to upscaling their use.

Clinicians and lay people tend to overestimate the effectiveness of a treatment when only the relative effect is presented, particularly if the relative effect is large, but the absolute effect is small. In recognition of this problem, item 17b of The Consolidated Standards of Reporting Trials (CONSORT) 2010 statement stipulates authors present both absolute and relative effects for binary outcomes in randomised controlled trials (RCTs). Adherence to item 17b and the effect of differing levels of CONSORT endorsement by journals on adherence is not well known. We assessed the extent to which item 17b is adhered to in 258 RCTs published in five leading medical journals (Annals of Internal Medicine, BMJ, JAMA, The Lancet and The New England Journal of Medicine) between January and December 2019 that all endorsed the CONSORT statement to varying degrees. Only 53 of 258 (20.5%; 95% CI 15.8% to 26.0%) included studies adhered fully to item 17b. Proportional adherence was higher in journals that endorsed the statement more strictly (BMJ and JAMA, 47.4% [34.0% to 61.0%]) compared with journals less strict in their endorsement (NEJM and Ann Intern Med, 12.2% [7.0% to 19.3%]; The Lancet, 14.1% [7.3% to 23.8%]). Journals that only recommend author adherence to CONSORT had a greater proportion of studies reporting only relative effects in the main results section (62.6%) and abstract (64.2%) compared with journals that require authors to submit a completed checklist (24.6% and 29.8%, respectively). The majority of RCTs (79.5%) with binary primary outcomes published in five leading medical journals during 2019 do not report both absolute and relative effect estimates as per item 17b of the CONSORT guideline despite its universal endorsement. Differences in adherence were observed between journals that endorsed the CONSORT statement to differing extents.
