A qualitative exploration of the barriers and enablers to supporting informal and familial carers within community pharmacies.

OBJECTIVES: There are approximately 5.3 million informal carers in the United Kingdom, many of whom support family in their health despite being unpaid and often unsupported. Many visit pharmacies to collect medicines and look for advice. This work explores informal carer support within community pharmacies (CP). METHODS: Semi-structured video interviews exploring perspectives on the role of CP in supporting carers were conducted in autumn 2022. The study received institutional ethical approval. Interviews were audio-recorded, transcribed verbatim, and analysed using a reflexive thematic approach. KEY FINDINGS: In total 25 interviews were conducted with 13 carers and 12 pharmacy staff. Three themes were identified:-What support do carers need through CP?-medicines management, navigating services, and carers health and wellbeing.-Barriers to CP better supporting carers-relationships with CP, carer needs, identification as a 'carer'.-Enablers to CP better supporting carers-support is a team effort, and CP as a community 'hub'. CONCLUSIONS: There is a trusted relationships between carers and pharmacy staff which can contribute to establishing pharmacies as a safe space of support, this includes medicines-specific support and navigating services, but also carer health and wellbeing support. Pharmacy staff may need to reconsider approaches to identifying and supporting carers and not just treating them as an extension of supporting a patient. In making this support accessible, relationships with pharmacy staff are important, as well as embracing CP as a 'community hub', although pharmacy staff may need training and information to facilitate them in this role.

Verapamil mitigates chloride and calcium bi-channelopathy in a myotonic dystrophy mouse model.

Myotonic dystrophy type 1 (DM1) involves misregulated alternative splicing for specific genes. We used exon or nucleotide deletion to mimic altered splicing of genes central to muscle excitation-contraction coupling in mice. Mice with forced skipping of exon 29 in the CaV1.1 calcium channel combined with loss of ClC-1 chloride channel function displayed markedly reduced lifespan, whereas other combinations of splicing mimics did not affect survival. The Ca2+/Cl- bi-channelopathy mice exhibited myotonia, weakness, and impairment of mobility and respiration. Chronic administration of the calcium channel blocker verapamil rescued survival and improved force generation, myotonia, and respiratory function. These results suggest that Ca2+/Cl- bi-channelopathy contributes to muscle impairment in DM1 and is potentially mitigated by common clinically available calcium channel blockers.

Diagnostic accuracy and clinical impact of MRI-based technologies for patients with non-alcoholic fatty liver disease: systematic review and economic evaluation.

Background: Magnetic resonance imaging-based technologies are non-invasive diagnostic tests that can be used to assess non-alcoholic fatty liver disease. Objectives: The study objectives were to assess the diagnostic test accuracy, clinical impact and cost-effectiveness of two magnetic resonance imaging-based technologies (LiverMultiScan and magnetic resonance elastography) for patients with non-alcoholic fatty liver disease for whom advanced fibrosis or cirrhosis had not been diagnosed and who had indeterminate results from fibrosis testing, or for whom transient elastography or acoustic radiation force impulse was unsuitable, or who had discordant results from fibrosis testing. Data sources: The data sources searched were MEDLINE, MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Database of Controlled Trials, Database of Abstracts of Reviews of Effects and the Health Technology Assessment. Methods: A systematic review was conducted using established methods. Diagnostic test accuracy estimates were calculated using bivariate models and a summary receiver operating characteristic curve was calculated using a hierarchical model. A simple decision-tree model was developed to generate cost-effectiveness results. Results: The diagnostic test accuracy review (13 studies) and the clinical impact review (11 studies) only included one study that provided evidence for patients who had indeterminate or discordant results from fibrosis testing. No studies of patients for whom transient elastography or acoustic radiation force impulse were unsuitable were identified. Depending on fibrosis level, relevant published LiverMultiScan diagnostic test accuracy results ranged from 50% to 88% (sensitivity) and from 42% to 75% (specificity). No magnetic resonance elastography diagnostic test accuracy data were available for the specific population of interest. Results from the clinical impact review suggested that acceptability of LiverMultiScan was generally positive. To explore how the decision to proceed to biopsy is influenced by magnetic resonance imaging-based technologies, the External Assessment Group presented cost-effectiveness analyses for LiverMultiScan plus biopsy versus biopsy only. Base-case incremental cost-effectiveness ratio per quality-adjusted life year gained results for seven of the eight diagnostic test strategies considered showed that LiverMultiScan plus biopsy was dominated by biopsy only; for the remaining strategy (Brunt grade ≥2), the incremental cost-effectiveness ratio per quality-adjusted life year gained was £1,266,511. Results from threshold and scenario analyses demonstrated that External Assessment Group base-case results were robust to plausible variations in the magnitude of key parameters. Limitations: Diagnostic test accuracy, clinical impact and cost-effectiveness data for magnetic resonance imaging-based technologies for the population that is the focus of this assessment were limited. Conclusions: Magnetic resonance imaging-based technologies may be useful to identify patients who may benefit from additional testing in the form of liver biopsy and those for whom this additional testing may not be necessary. However, there is a paucity of diagnostic test accuracy and clinical impact data for patients who have indeterminate results from fibrosis testing, for whom transient elastography or acoustic radiation force impulse are unsuitable or who had discordant results from fibrosis testing. Given the External Assessment Group cost-effectiveness analyses assumptions, the use of LiverMultiScan and magnetic resonance elastography for assessing non-alcoholic fatty liver disease for patients with inconclusive results from previous fibrosis testing is unlikely to be a cost-effective use of National Health Service resources compared with liver biopsy only. Study registration: This study is registered as PROSPERO CRD42021286891. Funding: Funding for this study was provided by the Evidence Synthesis Programme of the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 27, No. 10.

Non-alcoholic fatty liver disease includes a range of conditions that are caused by a build-up of fat in the liver, and not by alcohol consumption. This build-up of fat can cause inflammation. Persistent inflammation can cause scar tissue (fibrosis) to develop. It is important to identify patients with fibrosis because severe fibrosis can cause permanent liver damage (cirrhosis), which can lead to liver failure and liver cancer. In the National Health Service, patients with non-alcoholic fatty liver disease undergo tests to determine whether they have fibrosis. The test results are not always accurate and multiple tests can give conflicting results. Some of the tests may not be suitable for patients who have a very high body mass index. In the National Health Service, a liver biopsy may be offered to patients with inconclusive or conflicting test results or to those patients for whom other tests are unsuitable. However, liver biopsy is expensive, and is associated with side-effects such as pain and bleeding. Magnetic resonance imaging-based testing could be used as an extra test to help clinicians assess non-alcoholic fatty liver disease and identify patients who may need a liver biopsy. We assessed two magnetic resonance imaging-based diagnostic tests, LiverMultiScan and magnetic resonance elastography. LiverMultiScan is imaging software that is used alongside magnetic resonance imaging to measure markers of liver disease. Magnetic resonance elastography is used in some National Health Service centres to assess liver fibrosis; however, magnetic resonance elastography requires more equipment than just an magnetic resonance imaging scanner. We reviewed all studies examining how well LiverMultiScan and magnetic resonance elastography assess patients with non-alcoholic fatty liver disease. We also built an economic model to estimate the costs and benefits of using LiverMultiScan to identify patients who should be sent for a biopsy. Results from the model showed that LiverMultiScan may not provide good value for money to the National Health Service.

Derivation and independent validation of kidneyintelX.dkd: A prognostic test for the assessment of diabetic kidney disease progression.

AIMS: To develop and validate an updated version of KidneyIntelX (kidneyintelX.dkd) to stratify patients for risk of progression of diabetic kidney disease (DKD) stages 1 to 3, to simplify the test for clinical adoption and support an application to the US Food and Drug Administration regulatory pathway. METHODS: We used plasma biomarkers and clinical data from the Penn Medicine Biobank (PMBB) for training, and independent cohorts (BioMe and CANVAS) for validation. The primary outcome was progressive decline in kidney function (PDKF), defined by a ≥40% sustained decline in estimated glomerular filtration rate or end-stage kidney disease within 5 years of follow-up. RESULTS: In 573 PMBB participants with DKD, 15.4% experienced PDKF over a median of 3.7 years. We trained a random forest model using biomarkers and clinical variables. Among 657 BioMe participants and 1197 CANVAS participants, 11.7% and 7.5%, respectively, experienced PDKF. Based on training cut-offs, 57%, 35% and 8% of BioMe participants, and 56%, 38% and 6% of CANVAS participants were classified as having low-, moderate- and high-risk levels, respectively. The cumulative incidence at these risk levels was 5.9%, 21.2% and 66.9% in BioMe and 6.7%, 13.1% and 59.6% in CANVAS. After clinical risk factor adjustment, the adjusted hazard ratios were 7.7 (95% confidence interval [CI] 3.0-19.6) and 3.7 (95% CI 2.0-6.8) in BioMe, and 5.4 (95% CI 2.5-11.9) and 2.3 (95% CI 1.4-3.9) in CANVAS, for high- versus low-risk and moderate- versus low-risk levels, respectively. CONCLUSIONS: Using two independent cohorts and a clinical trial population, we validated an updated KidneyIntelX test (named kidneyintelX.dkd), which significantly enhanced risk stratification in patients with DKD for PDKF, independently from known risk factors for progression.

Monotherapy treatment of epilepsy in pregnancy: congenital malformation outcomes in the child.

BACKGROUND: Prenatal exposure to certain anti-seizure medications (ASMs) is associated with an increased risk of major congenital malformations (MCM). The majority of women with epilepsy continue taking ASMs throughout pregnancy and, therefore, information on the potential risks associated with ASM treatment is required. OBJECTIVES: To assess the effects of prenatal exposure to ASMs on the prevalence of MCM in the child. SEARCH METHODS: For the latest update of this review, we searched the following databases on 17 February 2022: Cochrane Register of Studies (CRS Web), MEDLINE (Ovid, 1946 to February 16, 2022), SCOPUS (1823 onwards), and ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP). No language restrictions were imposed. SELECTION CRITERIA: We included prospective cohort controlled studies, cohort studies set within pregnancy registries, randomised controlled trials and epidemiological studies using routine health record data. Participants were women with epilepsy taking ASMs; the two control groups were women without epilepsy and untreated women with epilepsy. DATA COLLECTION AND ANALYSIS: Five authors independently selected studies for inclusion. Eight authors completed data extraction and/or risk of bias assessments. The primary outcome was the presence of an MCM. Secondary outcomes included specific types of MCM. Where meta-analysis was not possible, we reviewed included studies narratively. MAIN RESULTS: From 12,296 abstracts, we reviewed 283 full-text publications which identified 49 studies with 128 publications between them. Data from ASM-exposed pregnancies were more numerous for prospective cohort studies (n = 17,963), than data currently available for epidemiological health record studies (n = 7913). The MCM risk for children of women without epilepsy was 2.1% (95% CI 1.5 to 3.0) in cohort studies and 3.3% (95% CI 1.5 to 7.1) in health record studies. The known risk associated with sodium valproate exposure was clear across comparisons with a pooled prevalence of 9.8% (95% CI 8.1 to 11.9) from cohort data and 9.7% (95% CI 7.1 to 13.4) from routine health record studies. This was elevated across almost all comparisons to other monotherapy ASMs, with the absolute risk differences ranging from 5% to 9%. Multiple studies found that the MCM risk is dose-dependent. Children exposed to carbamazepine had an increased MCM prevalence in both cohort studies (4.7%, 95% CI 3.7 to 5.9) and routine health record studies (4.0%, 95% CI 2.9 to 5.4) which was significantly higher than that for the children born to women without epilepsy for both cohort (RR 2.30, 95% CI 1.47 to 3.59) and routine health record studies (RR 1.14, 95% CI 0.80 to 1.64); with similar significant results in comparison to the children of women with untreated epilepsy for both cohort studies (RR 1.44, 95% CI 1.05 to 1.96) and routine health record studies (RR 1.42, 95% CI 1.10 to 1.83). For phenobarbital exposure, the prevalence was 6.3% (95% CI 4.8 to 8.3) and 8.8% (95% CI 0.0 to 9277.0) from cohort and routine health record data, respectively. This increased risk was significant in comparison to the children of women without epilepsy (RR 3.22, 95% CI 1.84 to 5.65) and those born to women with untreated epilepsy (RR 1.64, 95% CI 0.94 to 2.83) in cohort studies; data from routine health record studies was limited. For phenytoin exposure, the prevalence of MCM was elevated for cohort study data (5.4%, 95% CI 3.6 to 8.1) and routine health record data (6.8%, 95% CI 0.1 to 701.2). The prevalence of MCM was higher for phenytoin-exposed children in comparison to children of women without epilepsy (RR 3.81, 95% CI 1.91 to 7.57) and the children of women with untreated epilepsy (RR 2.01. 95% CI 1.29 to 3.12); there were no data from routine health record studies. Pooled data from cohort studies indicated a significantly increased MCM risk for children exposed to lamotrigine in comparison to children born to women without epilepsy (RR 1.99, 95% CI 1.16 to 3.39); with a risk difference (RD) indicating a 1% increased risk of MCM (RD 0.01. 95% CI 0.00 to 0.03). This was not replicated in the comparison to the children of women with untreated epilepsy (RR 1.04, 95% CI 0.66 to 1.63), which contained the largest group of lamotrigine-exposed children (> 2700). Further, a non-significant difference was also found both in comparison to the children of women without epilepsy (RR 1.19, 95% CI 0.86 to 1.64) and children born to women with untreated epilepsy (RR 1.00, 95% CI 0.79 to 1.28) from routine data studies. For levetiracetam exposure, pooled data provided similar risk ratios to women without epilepsy in cohort (RR 2.20, 95% CI 0.98 to 4.93) and routine health record studies (RR 0.67, 95% CI 0.17 to 2.66). This was supported by the pooled results from both cohort (RR 0.71, 95% CI 0.39 to 1.28) and routine health record studies (RR 0.82, 95% CI 0.39 to 1.71) when comparisons were made to the offspring of women with untreated epilepsy. For topiramate, the prevalence of MCM was 3.9% (95% CI 2.3 to 6.5) from cohort study data and 4.1% (0.0 to 27,050.1) from routine health record studies. Risk ratios were significantly higher for children exposed to topiramate in comparison to the children of women without epilepsy in cohort studies (RR 4.07, 95% CI 1.64 to 10.14) but not in a smaller comparison to the children of women with untreated epilepsy (RR 1.37, 95% CI 0.57 to 3.27); few data are currently available from routine health record studies. Exposure in utero to topiramate was also associated with significantly higher RRs in comparison to other ASMs for oro-facial clefts. Data for all other ASMs were extremely limited. Given the observational designs, all studies were at high risk of certain biases, but the biases observed across primary data collection studies and secondary use of routine health records were different and were, in part, complementary. Biases were balanced across the ASMs investigated, and it is unlikely that the differential results observed across the ASMs are solely explained by these biases. AUTHORS' CONCLUSIONS: Exposure in the womb to certain ASMs was associated with an increased risk of certain MCMs which, for many, is dose-dependent.

ANTECEDENTES: La exposición prenatal a determinados fármacos anticonvulsivos (FAC) se asocia con un mayor riesgo de malformaciones congénitas graves (MCG). La mayoría de las mujeres con epilepsia continúan tomando FAC durante todo el embarazo y, por lo tanto, se requiere información sobre los riesgos potenciales asociados con el tratamiento con FAC. OBJETIVOS: Evaluar los efectos de la exposición prenatal a los FAC sobre la prevalencia de MCG en el niño. MÉTODOS DE BÚSQUEDA: Para la última actualización de esta revisión se hicieron búsquedas el 17 de febrero de 2022 en las siguientes bases de datos: Registro Cochrane de Estudios (Cochrane Register of Studies [CRS Web]), MEDLINE (Ovid, 1946 hasta el 16 de febrero de 2022), SCOPUS (1823 en adelante) y ClinicalTrials.gov , Plataforma de registros internacionales de ensayos clínicos (ICTRP). No se impusieron restricciones de idioma. CRITERIOS DE SELECCIÓN: Se incluyeron estudios prospectivos controlados de cohortes, estudios de cohortes establecidos dentro de registros de embarazos, ensayos controlados aleatorizados y estudios epidemiológicos que utilizaron datos rutinarios de los historiales médicos. Las participantes fueron mujeres con epilepsia que tomaban FAC; los dos grupos de control fueron mujeres sin epilepsia y mujeres con epilepsia que no recibían tratamiento. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Cinco autores seleccionaron de forma independiente los estudios para inclusión. Ocho autores completaron la extracción de los datos y las evaluaciones del riesgo de sesgo. El desenlace principal fue la presencia de una MCG. Los desenlaces secundarios incluyeron tipos específicos de MCG. Cuando no fue posible realizar un metanálisis, los estudios incluidos se examinaron de forma narrativa. RESULTADOS PRINCIPALES: De 12 296 resúmenes, se revisaron 283 publicaciones a texto completo que identificaron 49 estudios con 128 publicaciones entre ellos. Los datos de los embarazos expuestos a FAC fueron más numerosos en el caso de los estudios prospectivos de cohortes (n = 17 963), que los datos actualmente disponibles de estudios de registros sanitarios epidemiológicos (n = 7913). El riesgo de MCG en los hijos de mujeres sin epilepsia fue del 2,1% (IC del 95%: 1,5 a 3,0) en los estudios de cohortes y del 3,3% (IC del 95%: 1,5 a 7,1) en los estudios de registros sanitarios. El riesgo conocido asociado con la exposición al valproato de sodio fue evidente en todas las comparaciones, con una prevalencia agrupada del 9,8% (IC del 95%: 8,1 a 11,9) a partir de los datos de los estudios de cohortes y del 9,7% (IC del 95%: 7,1 a 13,4) a partir de los estudios con datos rutinarios de los historiales médicos. Este fue elevado en casi todas las comparaciones con otros FAC como monoterapia, con diferencias absolutas de riesgo que variaron entre el 5% y el 9%. Múltiples estudios han constatado que el riesgo de MCG depende de la dosis. Los niños expuestos a la carbamazepina tuvieron una mayor prevalencia de MCG tanto en los estudios de cohortes (4,7%; IC del 95%: 3,7 a 5,9) como en los estudios con datos rutinarios de los historiales médicos (4,0%; IC del 95%: 2,9 a 5,4), que fue significativamente superior a la de los niños nacidos de mujeres sin epilepsia tanto en los estudios de cohortes (RR 2,30; IC del 95%: 1,47 a 3,59) como en los estudios de historias clínicas habituales (RR 1,14; IC del 95%: 0,80 a 1,64), con resultados significativos similares en comparación con los hijos de mujeres con epilepsia que no reciben tratamiento tanto en los estudios de cohortes (RR 1,44; IC del 95%: 1,05 a 1,96) como en los estudios con datos rutinarios de los historiales médicos (RR 1,42; IC del 95%: 1,10 a 1,83). Para la exposición al fenobarbital, la prevalencia fue del 6,3% (IC del 95%: 4,8 a 8,3) y del 8,8% IC del 95%: 0,0 a 9277,0) a partir de los datos de estudios de cohortes y los datos de estudios con datos rutinarios de los historiales médicos, respectivamente. Este aumento del riesgo fue significativo en comparación con los hijos de mujeres sin epilepsia (RR 3,22; IC del 95%: 1,84 a 5,65) y los nacidos de mujeres con epilepsia que no reciben tratamiento (RR 1,64; IC del 95%: 0,94 a 2,83) en estudios de cohortes; los datos procedentes de estudios con datos rutinarios de los historiales médicos fueron limitados. En cuanto a la exposición a la fenitoína, la prevalencia de MCG fue elevada en los datos de los estudios de cohortes (5,4%; IC del 95%: 3,6 a 8,1) y en los datos rutinarios de los historiales médicos (6,8%; IC del 95%: 0,1 a 701,2). La prevalencia de MCG fue mayor en los niños expuestos a la fenitoína en comparación con los hijos de mujeres sin epilepsia (RR 3,81; IC del 95%: 1,91 a 7,57) y los hijos de mujeres con epilepsia que no reciben tratamiento (RR 2,01; IC del 95%: 1,29 a 3,12); no hubo datos procedentes de estudios con datos rutinarios de los historiales médicos. Los datos agrupados de los estudios de cohortes indicaron un riesgo significativamente mayor de MCG en los niños expuestos a lamotrigina en comparación con los niños nacidos de mujeres sin epilepsia (RR 1,99; IC del 95%: 1,16 a 3,39); con una diferencia de riesgos (DR) que indica un riesgo 1% mayor de MCG (DR 0,01. IC del 95%: 0,00 a 0,03). Esto no se repitió en la comparación con los hijos de las mujeres con epilepsia que no reciben tratamiento (RR 1,04; IC del 95%: 0,66 a 1,63), que contenía el mayor grupo de niños expuestos a la lamotrigina (> 2700). Además, también se encontró una diferencia no significativa tanto en comparación con los hijos de mujeres sin epilepsia (RR 1,19; IC del 95%: 0,86 a 1,64) como con los hijos de mujeres con epilepsia que no reciben tratamiento (RR 1,00; IC del 95%: 0,79 a 1,28) a partir de los estudios con datos rutinarios. Para la exposición al levetiracetam, los datos agrupados proporcionaron razones de riesgos similares a las de las mujeres sin epilepsia en los estudios de cohortes (RR 2,20; IC del 95%: 0,98 a 4,93) y en los estudios con datos rutinarios de los historiales médicos (RR 0,67; IC del 95%: 0,17 a 2,66). Los resultados agrupados de los estudios de cohortes (RR: 0,71; IC del 95%: 0,39 a 1,28) y de los estudios con datos rutinarios de los historiales médicos (RR: 0,82; IC del 95%: 0,39 a 1,71) respaldan esta afirmación cuando se comparan con los hijos de las mujeres con epilepsia que no reciben tratamiento. En el caso del topiramato, la prevalencia de MCG fue del 3,9% (IC del 95%: 2,3 a 6,5) a partir de los datos de los estudios de cohortes y del 4,1% (0,0 a 27.050,1) a partir de los estudios con datos rutinarios de los historiales médicos. Las razones de riesgos fueron significativamente más altas para los niños expuestos al topiramato en comparación con los hijos de mujeres sin epilepsia en estudios de cohortes (RR 4,07; IC del 95%: 1,64 a 10,14), pero no en una comparación más pequeña con los hijos de mujeres con epilepsia que no reciben tratamiento (RR 1,37; IC del 95%: 0,57 a 3,27); actualmente se dispone de pocos datos a partir de estudios con datos rutinarios de los historiales médicos. La exposición en el útero al topiramato también se asoció con RR significativamente mayores en comparación con otros FAC para las hendiduras orofaciales. Los datos de todos las demás FAC fueron extremadamente limitados. Debido a los diseños observacionales, todos los estudios presentaron un alto riesgo de ciertos sesgos, pero los sesgos observados en los estudios de obtención de datos primarios y el uso secundario de historiales médicos rutinarios fueron diferentes y, en parte, complementarios. Los sesgos estaban equilibrados entre los FAC investigados, y es poco probable que los resultados diferenciales observados entre los FAC se expliquen únicamente por estos sesgos. CONCLUSIONES DE LOS AUTORES: La exposición en el útero a ciertos FAC se asoció con un mayor riesgo de ciertos MCG que, para muchos, depende de la dosis.

Combinatorial chloride and calcium channelopathy in myotonic dystrophy.

Myotonic dystrophy type 1 (DM1) involves misregulated alternative splicing for specific genes. We used exon or nucleotide deletion to mimic altered splicing of genes central to muscle excitation-contraction coupling processes in mice. Mice with forced-skipping of exon 29 in CaV1.1 calcium channel combined with loss of ClC-1 chloride channel function showed a markedly reduced lifespan, whereas other combinations of splicing mimics did not affect survival. The Ca2+/Cl- bi-channelopathy mice exhibited myotonia, weakness, and impairment of mobility and respiration. Chronic administration of the calcium channel blocker verapamil rescued survival and improved force generation, myotonia, and respiratory function. These results suggest that Ca2+/Cl- bi-channelopathy contributes to muscle impairment in DM1 and is potentially mitigated by common clinically available calcium channel blockers.

Calcium Hydroxylapatite-Induced Inflammatory Facial Edema and Induration Due to Hashimoto's Thyroiditis.

We describe a patient who experienced a diffuse, treatment-refractory facial inflammatory reaction following the injection of calcium hydroxylapatite with lidocaine. The reaction was attributed to undiagnosed Hashimoto's thyroiditis. Exogenous thyroid hormone replacement therapy rapidly resolved the facial inflammation associated with this type of autoimmune hypothyroidism.

Trastuzumab Deruxtecan for Treating HER2-Positive Unresectable or Metastatic Breast Cancer After Two or More Anti-HER2 Therapies: An Evidence Review Group Perspective of a NICE Single Technology Appraisal.

The National Institute for Health and Care Excellence (NICE) provides guidance to improve health and social care in England and Wales. NICE invited Daiichi Sankyo to submit evidence for the use of trastuzumab deruxtecan (T-DXd) for treating human epidermal growth factor 2 (HER2)-positive unresectable or metastatic breast cancer (UBC/MBC) after two or more anti-HER2 therapies, in accordance with NICE's Single Technology Appraisal process. The Liverpool Reviews and Implementation Group, part of the University of Liverpool, was commissioned to act as the Evidence Review Group (ERG). This article summarises the ERG's review of the evidence submitted by the company and provides an overview of the NICE Appraisal Committee's (AC's) final decision made in May 2021. Results from the company's base-case fully incremental analysis showed that, compared with T-DXd, eribulin and vinorelbine were dominated and the incremental cost-effectiveness ratio (ICER) per quality-adjusted life year (QALY) gained versus capecitabine was £47,230. The ERG scenario analyses generated a range of ICERs, with the highest being a scenario relating to a comparison of T-DXd versus capecitabine (£78,142 per QALY gained). The ERG considered that due to a lack of appropriate clinical effectiveness evidence, the relative effectiveness of T-DXd versus any comparator treatment could not be determined with any degree of certainty. The NICE AC agreed that the modelling of overall survival was highly uncertain and concluded that treatment with T-DXd could not be recommended for routine use within the National Health Service (NHS). T-DXd was, however, recommended for use within the Cancer Drugs Fund, provided Managed Access Agreement conditions were followed.

Saliva Cortisol as a Biomarker of Injury in Youth Sport-Related Concussion.

Increasing rates of sport-related concussion (SRC) in youth impose a significant burden on public health systems and the lives of young athletes. Accurate prediction for those likely to develop persistent post-concussion symptomology (PPCS) using a fluid biomarker, reflecting both acute injury and recovery processes, would provide the opportunity for early intervention. Cortisol, a stress hormone released through the hypothalamic-pituitary-adrenal (HPA) axis following injury, may provide a missing physiological link to clinical recovery. This cohort study investigated the change in saliva cortisol following SRC and the association between cortisol and symptom burden in pediatric ice hockey players. Further, the association between cortisol levels and medical clearance to return to play was explored. In total, cortisol samples from 233 players were included; 165 athletes (23.6% female) provided pre-injury saliva and 68 athletes (19.1% female) provided post-SRC saliva samples for cortisol analysis. Quantile (median) regressions were used to compare cortisol between pre-injury and post-SRC groups, and the association between total symptoms (/22) and symptom severity scores (/132) reported on the Sport Concussion Assessment Tool (SCAT)3/SCAT5 and post-SRC cortisol (adjusting for age, sex, history of concussion, and time from injury to sample collection). Results demonstrated significantly lower saliva cortisol in post-SRC athletes compared with the pre-injury group (ß = -0.62, 95% confidence interval [CI; -1.08, -0.16], p = 0.009). Post-SRC cortisol was not significantly associated with the SCAT3/SCAT5 symptom totals or symptom severity scores; however, females were found to report more symptoms (ß = 6.95, 95% CI [0.35, 13.55], p = 0.040) and greater symptom severity (ß = 23.87, 95% CI [9.58, 38.15], p = 0.002) compared with males. Exploratory time-to-event analysis revealed a point estimate suggesting a potential association between low cortisol levels and days to medical clearance to return to play. Although preliminary, these findings suggest that the HPA axis may be dysregulated post-SRC. Further, our exploratory analysis and case presentation of post-injury outliers highlight the need to further research cortisol as a prognostic biomarker to inform individualized sex-specific care after SRC.

Efficient suppression of endogenous CFTR nonsense mutations using anticodon-engineered transfer RNAs.

Nonsense mutations or premature termination codons (PTCs) comprise ∼11% of all genetic lesions, which result in over 7,000 distinct genetic diseases. Due to their outsized impact on human health, considerable effort has been made to find therapies for nonsense-associated diseases. Suppressor tRNAs have long been identified as a possible therapeutic for nonsense-associated diseases; however, their ability to inhibit nonsense-mediated mRNA decay (NMD) and support significant protein translation from endogenous transcripts has not been determined in mammalian cells. Here, we investigated the ability of anticodon edited (ACE)-tRNAs to suppress cystic fibrosis (CF) causing PTCs in the cystic fibrosis transmembrane regulator (CFTR) gene in gene-edited immortalized human bronchial epithelial (16HBEge) cells. Delivery of ACE-tRNAs to 16HBEge cells harboring three common CF mutations G542XUGA-, R1162XUGA-, and W1282XUGA-CFTR PTCs significantly inhibited NMD and rescued endogenous mRNA expression. Furthermore, delivery of our highly active leucine-encoding ACE-tRNA resulted in rescue of W1282X-CFTR channel function to levels that significantly exceed the necessary CFTR channel function for therapeutic relevance. This study establishes the ACE-tRNA approach as a potential standalone therapeutic for nonsense-associated diseases due to its ability to rescue both mRNA and full-length protein expression from PTC-containing endogenous genes.

Connecting the Dots from Professional Development to Student Learning.

Following professional development (PD), implementation of contemporary topics into high school biology requires teachers to make critical decisions regarding integration of novel content into existing course scope and sequence. Often exciting topics, such as neuroscience, do not perfectly align with standards. Despite commitment to enacting what was learned in the PD, teachers must adapt novel content to their perceptions of good teaching, local context, prior knowledge of their students, and state and district expectations. How teachers decide to integrate curricula encountered from PD programs may affect student outcomes. This mixed-methods study examined the relationship between curricular application strategies following an inquiry-based neuroscience PD and student learning. Post-PD curricular implementation was measured qualitatively through analysis of teacher action plans and classroom observations and quantitatively using hierarchical linear modeling to determine the impact of implementation on student performance. Participation in neuroscience PD predicted improved student learning compared with control teachers. Of the two distinct curricular implementation strategies, enacting a full unit produced significantly greater student learning than integrating neuroscience activities into existing biology units. Insights from this analysis should inform teacher implementation of new curricula after PD on other contemporary biology topics.

Cortisol reactivity to stress predicts behavioral responsivity to reward moderation by sex, depression, and anhedonia.

Depression is associated with blunted reactivity to acute stress, as well as blunted responsivity to rewards. However, the extent to which responses to stress are associated with responses to reward in individuals meeting criteria for a depressive disorder is unknown. The goal of this study was to examine the relation of responses to stress and reward, and to determine if this relation is moderated by depression diagnosis, anhedonia, and sex. Participants included 114 adults (68 depressed, 46 non-depressed; 75% women) recruited from the community. Stress reactivity was operationalized as the total salivary cortisol output to the Trier Social Stress Test (TSST; Kirschbaum et al., 1993). Response bias to monetary reward was assessed following the TSST recovery period with a probabilistic reward task (PRT; Pizzagalli et al., 2005). In men only, total cortisol output during the TSST was more strongly positively associated with response bias to reward across the three blocks of the PRT. In addition, among depressed participants with high levels of anhedonia, higher cortisol output during the TSST was significantly associated with higher overall response bias to reward. We suggest that in men, the stress and reward systems may both respond quickly, and resolve rapidly, in the face of acute stress. Further, in depression, our findings suggest that anhedonia may represent a specific phenotype in which the stress and reward systems are particularly tuned together.

Sensation-Seeking and Impulsivity in Athletes with Sport-Related Concussion.

PURPOSE OF REVIEW: Sport-related concussion (SRC) is a significant public health problem. Understanding the behavioral and personal factors that influence risk and incidence of SRC is critically important for appropriate care and management. Sensation-seeking and impulsivity have been posited to be two such factors that may be significantly associated with SRC. We performed a focused review of recent evidence of the relationships between sensation-seeking and impulsivity in athletes with SRC. RECENT FINDINGS: While the research is relatively limited, extant findings demonstrate a significant relationship between sensation-seeking and contact sport participation and risk of prior and future SRC. Impulsivity appears to be common among athletes competing in high contact sports and may contribute to neural and functional brain changes following SRC; however, causal relationships between impulsivity, contact sport participation, and SRC have not been demonstrated. Both sensation-seeking and impulsivity are significantly associated with SRC in collegiate athletes. Interventions designed to ameliorate high levels of these constructs may prove to be beneficial avenues to reducing SRC risk and improving patient care and outcomes.

Cognitive-behavioural therapy for a variety of conditions: an overview of systematic reviews and panoramic meta-analysis.

BACKGROUND: Cognitive-behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive-behavioural therapy systematic reviews suggested that cognitive-behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials. OBJECTIVES: This project was undertaken to map the quality and gaps in the cognitive-behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive-behavioural therapy. DATA SOURCES: The overview was designed with cognitive-behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019. REVIEW METHODS: Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive-behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive-behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I2 < 75%, we pooled across conditions. Subgroup analyses were conducted for age, delivery format, comparator type and length of follow-up, and a sensitivity analysis was performed for quality. RESULTS: A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive-behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive-behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.05 to 0.50, I2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval -0.28 to 0.88, I2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.28 to 0.74, I2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions. LIMITATIONS: Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them. CONCLUSION: Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive-behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes. FUTURE WORK: Future research should focus on how the modest effect sizes seen with cognitive-behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

This report is a summary of research examining if a psychological therapy called cognitive­behavioural therapy can improve the quality of life of people living with physical and/or mental conditions. Cognitive­behavioural therapy uses a set of techniques that help individuals to identify and change problematic thoughts or behaviour patterns that might contribute to and maintain their physical or mental symptoms. It can be delivered face to face or through mediums such as the internet. We aimed to understand if cognitive­behavioural therapy helps patients with specific conditions only, or if it can help patients with any condition. We searched relevant databases to find articles that combine the results from multiple trials testing cognitive­behavioural therapy. These are known as systematic reviews. We graded these reviews as providing good- or poor-quality evidence. We identified the conditions for which we had good-quality evidence on whether or not cognitive­behavioural therapy was helpful. From each review, we took numerical data that told us if cognitive­behavioural therapy improved quality of life for that specific condition. Next, we combined all the numerical data together, across all the conditions, to see if there was a consistent benefit of cognitive­behavioural therapy. The statistical analyses found that cognitive­behavioural therapy consistently improved quality of life across all the conditions where it has been tested. We have evidence that it can help children, adolescents and adults, of either sex, who are living in Europe, North America and Australasia. We are unsure if it will help older adults or people living in Africa, Asia or South America, nor do we know if cognitive­behavioural therapy is equally effective across different ethnic groups. It is recommended that future research should prioritise understanding how cognitive­behavioural therapy works, why some people do not want to use cognitive­behavioural therapy and why some patients do not benefit from it.

The evidence for cognitive behavioural therapy in any condition, population or context: a meta-review of systematic reviews and panoramic meta-analysis.

The majority of psychological treatment research is dedicated to investigating the effectiveness of cognitive behavioural therapy (CBT) across different conditions, population and contexts. We aimed to summarise the current systematic review evidence and evaluate the consistency of CBT's effect across different conditions. We included reviews of CBT randomised controlled trials in any: population, condition, format, context, with any type of comparator and published in English. We searched DARE, Cochrane, MEDLINE, EMBASE, PsycINFO, CINAHL, CDAS, and OpenGrey between 1992 and January 2019. Reviews were quality assessed, their data extracted and summarised. The effects upon health-related quality of life (HRQoL) were pooled, within-condition groups. If the across-condition heterogeneity was I2 < 75%, we pooled effects using a random-effect panoramic meta-analysis. We summarised 494 reviews (221 128 participants), representing 14/20 physical and 13/20 mental conditions (World Health Organisation's International Classification of Diseases). Most reviews were lower-quality (351/494), investigated face-to-face CBT (397/494), and in adults (378/494). Few reviews included trials conducted in Asia, South America or Africa (45/494). CBT produced a modest benefit across-conditions on HRQoL (standardised mean difference 0.23; 95% confidence intervals 0.14-0.33, I2 = 32%). The effect's associated prediction interval -0.05 to 0.50 suggested CBT will remain effective in conditions for which we do not currently have available evidence. While there remain some gaps in the completeness of the evidence base, we need to recognise the consistent evidence for the general benefit which CBT offers.

Sublethal, sex-specific, osmotic, and metabolic impairments in embryonic and adult round stingrays from a location exposed to environmental contamination in southern California, USA.

Organic contaminants are known to affect a suite of physiological processes across vertebrate clades. However, despite their ancient lineage and important roles in maintaining healthy ecosystems, elasmobranchs (sharks, skates, and rays) are understudied with regard to sublethal effects of contaminant exposure on metabolic processes. Perturbations resulting from contaminant exposure can divert energy away from maintaining physiological homeostasis, particularly during energetically challenging life stages, such as pregnancy and embryonic development. Using the round stingray (Urobatis halleri) as a model elasmobranch species, we captured adult males and pregnant females (matrotrophic histotrophy) and their embryos from two populations differing in their environmental exposure to organic contaminants (primarily polychlorinated biphenyls (PCBs)). Pregnant females from the PCB-exposed population experienced significant decreases from early- to late-pregnancy in tissue mass and quality not seen in reference females. PCB-exposed pregnant females also failed to maintain plasma urea concentrations as pregnancy progressed, which was accompanied by a loss in muscle protein content. Despite the energetic demands of late-term pregnancy, females had significantly greater liver lipid content than reproductively inactive adult males. PCB-exposed adult males also had high metabolic capacity (i.e., enzyme activity) for most substrate groupings of all sex-site groups, suggesting that males may be even more negatively impacted by contaminant exposure than pregnant females. Evidence that in utero exposure to PCBs via maternal offloading impairs embryo outcomes is accumulating. Embryos from the PCB-contaminated site had lower tissue quality measures and indications that sex-based differences were manifesting in utero as males had higher metabolic capacities than females. This study indicates that accumulated PCB contaminants are not physiologically inert in the stingray.

Making Sense of "Somatization": A Systematic Review of its Relationship to Pediatric Pain.

OBJECTIVES: Pain and other physical symptoms commonly co-occur in childhood. There is debate about the relevance of somatization in understanding pain. The present review critically appraised and synthesized the extant literature on the relationship between pediatric pain and somatization. METHODS: A systematic review (PROSPERO registration #95956) was conducted in Medline, PsycINFO, EMBASE, and CINAHL using search terms related to pain and somatization in children and adolescents. A total of 156 articles were eligible for inclusion in the review. For studies that measured somatization using a symptom questionnaire, descriptions of "somatization" were extracted. Data regarding the relationship between pain and somatization were extracted for studies measuring somatization using a diagnostic category (e.g., Somatic Symptom and Related Disorders [SSRDs]). RESULTS: While many studies using somatic symptom questionnaires described somatization as having a psychological component, this was not always captured in measurement tools. Pain was reported as a common symptom in patients with an SSRD diagnosis, though rates varied depending on the specific diagnosis and pain location. Rates of SSRD diagnoses among pain patients were less frequent than rates of pain amongst SSRD patients. CONCLUSIONS: SSRDs and pain commonly co-occur, though rates differ depending on diagnosis and pain location. Understanding the relationship between pain and somatization is complicated by the discrepancy between how somatization is defined and measured in questionnaire studies. A comprehensive and measurable definition of somatization is needed so researchers can better identify the shared and unique contributions of pain and somatization in pediatric populations.

Substrates and Clearance Products of Fetal Adrenal Glucocorticoid Synthesis in Full-Term Human Umbilical Circulation.

In full-term elective caesarian sections, fetal flow of adrenal substrate steroids to products differs by sex, with males (M) in molar equilibrium whereas females (F) add net molarity and synthesize more cortisol. Using the same sampling design, paired, full-term, arterial, and venous umbilical cord samples and intrapartum chart records were obtained at the time of vaginal delivery (N = 167, 85 male) or emergency C-section (N = 38, 22 male). Eight steroids were quantified by liquid chromatography coupled to tandem mass spectrometry (adrenal glucocorticoids [cortisol, corticosterone], sequential cortisol precursor steroids [17-hydroxyprogesterone, 11-deoxycortisol], cortisol and corticosterone metabolites [cortisone and 11-dehydrocorticosterone], and gonadal steroids [androstenedione, testosterone]). Fetal sex was not significant in any analytic models. Going through both phase 1 and phase 2 labor increased fetal adrenal steroidogenesis and decreased male testosterone relative to emergency C-sections that do not reach stage 2 of labor (ie, head compressions) and elective C-sections with no labor. Sum adrenal steroid molarity arriving in venous serum was almost double the equivalent metric for deliveries without labor. No effects of operative vaginal delivery were noted. Maternal regional anesthetic suppressed venous concentrations, and fetal synthesis replaced that steroid. Approximate molar equivalence between substrate pool depletion and net glucocorticoid synthesis was seen. Paired venous and arterial umbilical cord serum has the potential to identify sex differences that underlie antenatal programming of hypothalamic-pituitary-adrenal axis function in later life. However, stage 2 labor before the collection of serum, and regional anesthetic for the mother, mask those sex differences.
