Background Lysosomal storage diseases (LSDs) are inherited metabolic disorders that may lead to severe multi-organ disease. Current ERTs are limited by anti-drug antibodies, the blood–brain barrier, and early disease onset and progression before ERT is started. We have opened a phase I clinical trial of enzyme replacement therapy (ERT) for fetuses with LSDs (NCT04532047). We evaluated the attitudes of parents and patients with LSDs towards fetal clinical trials and therapies. Methods A multidisciplinary team designed a survey which was distributed by five international patient advocacy groups. We collected patients’ demographic, diagnostic, and treatment information. Associations between respondent characteristics and attitudes towards fetal therapies/trials were analyzed using multivariate ordinal logistic regression. Results The survey was completed by 181 adults from 19 countries. The majority of respondents were mothers from the United States. The most common diseases were MPS1 (26%), MPS3 (19%), and infantile-onset Pompe (14%). Most patients (88%) were diagnosed after birth, at a median of 21 months. Altogether, 65% of participating patients and children of participants had received ERT, 27% a stem cell transplant, and 4% gene therapy. We found that half (49%) of respondents were unlikely to terminate a future affected pregnancy, 55% would enroll in a phase I clinical trial for fetal ERT, and 46% would enroll in a fetal gene therapy trial. Respondents who received postnatal ERT were significantly more likely enroll in a trial for fetal ERT or gene therapy (ERT OR 4.48, 95% CI 2.13–9.44, p < 0.0001; gene therapy OR 3.03, 95% CI 1.43–6.43, p = 0.0038). Respondents who used clinicaltrials.gov as a main source of information were more likely to choose to participate in a fetal trial (ERT OR 2.43, 95% CI 1.18–5.01, p = 0.016; gene therapy OR 2.86, 95% CI 1.27–6.46, p = 0.011). Conclusions Familiarity with postnatal ERT increased respondents’ likelihood of pursuing fetal therapies. Families who use clinicaltrials.gov may be more receptive to innovative fetal treatments. The patient community has a favorable attitude towards fetal therapy; over half of respondents would enroll in a phase I clinical trial to assess the safety and efficacy of fetal ERT.

This paper attends to the sociality available in the clozapine clinic regimen and suggests that the social dimensions of clozapine treatment may be as important as the biochemical efficacy of clozapine. The clozapine clinic is where people diagnosed with chronic schizophrenia who take the antipsychotic clozapine go for routine monitoring of clozapine side effects, particularly haematological effects. Psychopharmaceutical treatments are often criticized for being reductionistic and dehumanizing, but clozapine clinics offer increased clinical contact in the age of deinstitutionalization. The inadvertent social benefits of biomedically reductive treatments have not previously been ethnographically attended to in the clozapine-only context. Drawing on 18 months of ethnographic fieldwork with 43 clozapine clients and 16 clinical caregivers in two clozapine clinics in the United Kingdom in Australia, I argue that routine clinical attachments in the clozapine clinic can serve a therapeutic role in terms of providing opportunities for clients’ health agency, social competence and accountability. This socio-therapeutic quality appeared to be available because the clinical emphasis was not on psychotic illness. It depended, however, on reliable and familiar social exchanges inside the clinic and on the predictability of clinical activity. The importance of unemotional but unfailing relationships and rhythms in the clozapine clinic context echoes cross-cultural findings about how schizophrenia is managed more productively in environments that invite more neutral and equal social exchanges.

Well-being perception is seldom explored in schizophrenia patients. Recurrent limitations, such as the questionable applicability of gold standard definitions of health and well-being, and fewer tools available to assess well-being, are pronounced in this subpopulation. This cross-sectional study sought to explore potential clinical factors that may predict subjective well-being scores in chronic schizophrenia patients (N=142) receiving clozapine treatment. The Short Warwick–Edinburgh Mental Well-being Scale (SWEMWBS) was used to measure well-being. We correlated SWEMWBS scores and 27 clinically recognized factors, spanning socio-demographics, symptom severity scores, physical health diagnosis, clozapine side effects, habits and prescribed medication. Factors with a p<0.2 correlation were included as a predictors in a linear regression model. Ten factors were included in the linear regression model, however only positive symptom severity was a significant predictor of SWEMWBS score (p<0.0001). We suggest that greater levels of clinical attention given to positive symptoms compared with other symptoms and aspects of well-being, during biomedical treatment for chronic schizophrenia, may partially explain the finding that only positive symptoms significantly predicted patient perceptions of low well-being.

It is well recognised that antipsychotic treatments impact the whole body, not just the target area of the brain. For people with refractory schizophrenia on clozapine, the gold standard antipsychotic treatment in England and Australia, the separation of mental and physical regimes of health is particularly pronounced, resulting in multiple, compartmentalised treatment registers. Clinicians often focus on the mental health aspects of clozapine use, using physical indicators to determine whether treatment can continue. Our observations of 59 participants in England and Australia over 18 months revealed that patients did not observe this hierarchisation of mental treatments and physical outcomes. Patients often actively engaged in the management of their bodily symptoms, leading us to advance the figure of the active, rather than passive, patient. In our paper, we do not take the position that the facility for active management is a special one utilised only by these patients. We seek instead to draw attention to what is currently overlooked as an ordinary capacity to enact some sort of control over life, even under ostensibly confined and confining circumstances. We argue that clozapine-treated schizophrenia patients utilise the clinical dichotomy between mental and physical domains of health to rework what health means to them. This permits patients to actively manage their own phenomenological ‘life projects’ (Rapport, I am Dynamite: an Alternative Anthropology of Power, Routledge, London 2003 ), and forces us to reconsider the notion of clinical giveness of what health means. This making of one’s own meanings of health may be critical to the maintenance of a sense of self.

Genetic variants in SLC22A5, encoding the membrane carnitine transporter OCTN2, cause the rare metabolic disorder Carnitine Transporter Deficiency (CTD). CTD is potentially lethal but actionable if detected early, with confirmatory diagnosis involving sequencing of SLC22A5. Interpretation of missense variants of uncertain significance (VUSs) is a major challenge. In this study, we sought to characterize the largest set to date (n = 150) of OCTN2 variants identified in diverse ancestral populations, with the goals of furthering our understanding of the mechanisms leading to OCTN2 loss-of-function (LOF) and creating a protein-specific variant effect prediction model for OCTN2 function. Uptake assays with 14C-carnitine revealed that 105 variants (70%) significantly reduced transport of carnitine compared to wild-type OCTN2, and 37 variants (25%) severely reduced function to less than 20%. All ancestral populations harbored LOF variants; 62% of green fluorescent protein (GFP)–tagged variants impaired OCTN2 localization to the plasma membrane of human embryonic kidney (HEK293T) cells, and subcellular localization significantly associated with function, revealing a major LOF mechanism of interest for CTD. With these data, we trained a model to classify variants as functional (>20% function) or LOF (<20% function). Our model outperformed existing state-of-the-art methods as evaluated by multiple performance metrics, with mean area under the receiver operating characteristic curve (AUROC) of 0.895 ± 0.025. In summary, in this study we generated a rich dataset of OCTN2 variant function and localization, revealed important disease-causing mechanisms, and improved upon machine learning–based prediction of OCTN2 variant function to aid in variant interpretation in the diagnosis and treatment of CTD.

In an open-label, randomized study involving men who have sex with men, doxycycline use after high-risk sexual exposure reduced the incidence of sexually transmitted infections (chlamydia, gonorrhea, and syphilis).

Localised prostate cancer is commonly treated with external beam radiotherapy and moderate hypofractionation is non-inferior to longer schedules. Stereotactic body radiotherapy (SBRT) allows shorter treatment courses without impacting acute toxicity. We report 2-year toxicity findings from PACE-B, a randomised trial of conventionally fractionated or moderately hypofractionated radiotherapy versus SBRT. PACE is an open-label, multicohort, randomised, controlled, phase 3 trial conducted at 35 hospitals in the UK, Ireland, and Canada. In PACE-B, men aged 18 years and older with a WHO performance status 0–2 and low-risk or intermediate-risk histologically-confirmed prostate adenocarcinoma (Gleason 4 + 3 excluded) were randomly allocated (1:1) by computerised central randomisation with permuted blocks (size four and six), stratified by centre and risk group to control radiotherapy (CRT; 78 Gy in 39 fractions over 7·8 weeks or, following protocol amendment on March 24, 2016, 62 Gy in 20 fractions over 4 weeks) or SBRT (36·25 Gy in five fractions over 1–2 weeks). Androgen deprivation was not permitted. Co-primary outcomes for this toxicity analysis were Radiation Therapy Oncology Group (RTOG) grade 2 or worse gastrointestinal and genitourinary toxicity at 24 months after radiotherapy. Analysis was by treatment received and included all patients with at least one fraction of study treatment assessed for late toxicity. Recruitment is complete. Follow-up for oncological outcomes continues. The trial is registered with ClinicalTrials.gov, NCT01584258. We enrolled and randomly assigned 874 men between Aug 7, 2012, and Jan 4, 2018 (441 to CRT and 433 to SBRT). In this analysis, 430 patients were analysed in the CRT group and 414 in the SBRT group; a total of 844 (97%) of 874 randomly assigned patients. At 24 months, RTOG grade 2 or worse genitourinary toxicity was seen in eight (2%) of 381 participants assigned to CRT and 13 (3%) of 384 participants assigned to SBRT (absolute difference 1·3% [95% CI –1·3 to 4·0]; p=0·39); RTOG grade 2 or worse gastrointestinal toxicity was seen in 11 (3%) of 382 participants in the CRT group versus six (2%) of 384 participants in the SBRT group (absolute difference –1·3% [95% CI –3·9 to 1·1]; p=0·32). No serious adverse events (defined as RTOG grade 4 or worse) or treatment-related deaths were reported within the analysis timeframe. In the PACE-B trial, 2-year RTOG toxicity rates were similar for five fraction SBRT and conventional schedules of radiotherapy. Prostate SBRT was found to be safe and associated with low rates of side-effects. Biochemical outcomes are awaited. Accuray.

The design of stable adsorbents capable of selectively capturing dioxygen with a high reversible capacity is a crucial goal in functional materials development. Drawing inspiration from biological O 2 carriers, we demonstrate that coupling metal-based electron transfer with secondary coordination sphere effects in the metal–organic framework Co 2 (OH) 2 (bbta) (H 2 bbta = 1 H ,5 H -benzo(1,2- d: 4,5- d ′)bistriazole) leads to strong and reversible adsorption of O 2 . In particular, moderate-strength hydrogen bonding stabilizes a cobalt(III)-superoxo species formed upon O 2 adsorption. Notably, O 2 -binding in this material weakens as a function of loading, as a result of negative cooperativity arising from electronic effects within the extended framework lattice. This unprecedented behavior extends the tunable properties that can be used to design metal–organic frameworks for adsorption-based applications. Oxygen capture is attractive for catalysis, sensing, and separations, but engineering stable and selective adsorbents is challenging. Here the authors combine metal-based electron transfer with secondary coordination sphere effects in a metal-organic framework, leading to strong and reversible O 2 adsorption that also exhibits negative cooperativity.

There is growing evidence of a camouflaging effect among females with autism spectrum disorder (ASD), particularly among those without intellectual disability, which may affect performance on gold-standard diagnostic measures. This study utilized an age- and IQ-matched sample of school-aged youth (n = 228) diagnosed with ASD to assess sex differences on the ADOS and ADI-R, parent-reported autistic traits, and adaptive skills. Although females and males were rated similarly on gold-standard diagnostic measures overall, females with higher IQs were less likely to meet criteria on the ADI-R. Females were also found to be significantly more impaired on parent reported autistic traits and adaptive skills. Overall, the findings suggest that some autistic females may be missed by current diagnostic procedures.

Young male cancer survivors have lower testosterone levels, higher fat mass, and worse quality of life (QoL) than age-matched healthy controls. Low testosterone in cancer survivors can be due to orchidectomy or effects of chemotherapy and radiotherapy. We have undertaken a double-blind, placebo-controlled, 6-month trial of testosterone replacement in young male cancer survivors with borderline low testosterone (7-12 nmol/l). This was a multicentre United Kingdom study conducted in secondary care hospital outpatients. Male survivors of testicular cancer, lymphoma, and leukaemia aged 25-50 years with morning total serum testosterone 7-12 nmol/l were recruited. A total of 136 men were randomised between July 2012 and February 2015 (42.6% aged 25-37 years, 57.4% 38-50 years, 88% testicular cancer, 10% lymphoma, matched for body mass index [BMI]). Participants were randomised 1:1 to receive testosterone (Tostran 2% gel) or placebo for 26 weeks. A dose titration was performed after 2 weeks. The coprimary end points were trunk fat mass and SF36 Physical Functioning score (SF36-PF) at 26 weeks by intention to treat. At 26 weeks, testosterone treatment compared with placebo was associated with decreased trunk fat mass (-0.9 kg, 95% CI -1.6 to -0.3, p = 0.0073), decreased whole-body fat mass (-1.8 kg, 95% CI -2.9 to -0.7, p = 0.0016), and increased lean body mass (1.5 kg, 95% CI 0.9-2.1, p < 0.001). Decrease in fat mass was greatest in those with a high truncal fat mass at baseline. There was no treatment effect on SF36-PF or any other QoL scores. Testosterone treatment was well tolerated. The limitations of our study were as follows: a relatively short duration of treatment, only three cancer groups included, and no hard end point data such as cardiovascular events. In young male cancer survivors with low-normal morning total serum testosterone, replacement with testosterone is associated with an improvement in body composition.
