Abstract
SummaryThere have been previous suggestions in the literature of a link between schizophrenia and retinitis pigmentosa (RP) or its associated syndromes. In this article, we describe two cases of schizophrenía and two cases of delusional disorder occurring in patients with RP. We explore possible reasons for an association between RP and schizophrenia including shared genetic predisposition, sensory deprivation, coarse brain disease and retinoid dysregulation. Awareness of an association may help to direct future research into the aetiology of these disorders, especially in the areas of neurochemistry and medical genetics.

Obstetric complications in patients with schizophrenia and their unaffected siblings. Eur Psychiatry 2020; 20:28-34.

Abstract
AbstractObjectiveWe sought to explore whether obstetric complications (OCs) are more likely to occur in the presence of familial/genetic susceptibility for schizophrenia or whether they themselves represent an independent environmental risk factor for schizophrenia.MethodsThe presence of OCs was assessed through maternal interview on 216 subjects, comprising 36 patients with schizophrenia from multiply affected families, 38 of their unaffected siblings, 31 schizophrenic patients with no family history of psychosis, 51 of their unaffected siblings and 60 normal comparison subjects. We examined the familiality of OCs and whether OCs were commoner in the patient and sibling groups than in the control group.ResultsOCs tended to cluster within families, especially in multiply affected families. Patients with schizophrenia, especially those from multiply affected families, had a significantly higher rate of OCs compared to normal comparison subjects, but there was no evidence for an elevated rate of OCs in unaffected siblings.ConclusionOur data provides little evidence for a link between OCs and genetic susceptibility to schizophrenia. If high rates of OCs are related to schizophrenia genes, this relationship is weak and will only be detected by very large sample sizes.

Abstract
AbstractP300 wave anomalies correlate with genetic risk for schizophrenia and constitute a plausible endophenotype for the disease. The COMT gene is thought to influence cognitive performance and to be a susceptibility gene for schizophrenia. Unlike two previous studies, we found no significant influence of the COMT gene on P300 amplitude or latency in 189 individuals examined. The well-supported role of the COMT gene both in dopamine catabolism as well as in prefrontal cognition makes a strong theoretical case for the influence of COMT Val158Met polymorphism on P300 endophenotypes. However, the available neurophysiologic evidence suggests that any such association, if present, must be very subtle.

Abstract
IntroductionInvoluntary admission and treatment is often a traumatic experience for patients and there is a wide variation in attitudes towards care even when patients are recovered.Objectives/aimsThe purpose of this large prospective study was to identify clinical predictors of attitudes towards care during involuntary admission.MethodsThree hundred and ninety-one consecutively admitted involuntarily patients to three psychiatric inpatient units over a 30-month period were invited to participate in the study. Comprehensive assessments at admission and 3 months after discharge were attained including measures of symptoms, insight, functioning, attitudes towards involuntary admission and coercive experiences. Multiple linear regression modelling was used to determine the optimal explanatory variables for attitudes towards care.ResultsTwo hundred and sixty-three individuals participated at baseline and 156 (59%) successfully completed follow-up assessments. Individuals improved significantly over time clinically and in their attitudes towards their care. At baseline greater insight (P < 0.001) and less symptoms (P = 0.02) were associated with more positive attitudes towards care as was older age (P = 0.001). At follow-up, greater insight (P < 0.001), less symptoms (P = 0.02) and being older (P = 0.04) were associated with more positive attitudes towards care. More positive attitudes towards care at follow-up were associated with greater improvements in insight over time (P < 0.001) and having a diagnosis of an affective psychosis (P = 0.0009).ConclusionsThe best predictors of positive attitudes towards care during and after involuntary admission are illness related factors, such as levels of insight and improvement in insight, rather than service or legislation related factors, such as the use of coercive measures, seclusion and restraint.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Week 48 Resistance Analyses of the Once-Daily, Single-Tablet Regimen Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (D/C/F/TAF) in Adults Living with HIV-1 from the Phase III Randomized AMBER and EMERALD Trials. AIDS Res Hum Retroviruses 2020; 36:48-57.

Abstract
Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg is being investigated in two Phase III trials, AMBER (NCT02431247; treatment-naive adults) and EMERALD (NCT02269917; treatment-experienced, virologically suppressed adults). Week 48 AMBER and EMERALD resistance analyses are presented. Postbaseline samples for genotyping/phenotyping were analyzed from protocol-defined virologic failures (PDVFs) with viral load (VL) ≥400 copies/mL at failure/later time points. Post hoc analyses were deep sequencing in AMBER, and HIV-1 proviral DNA from baseline samples (VL <50 copies/mL) in EMERALD. Through week 48 across both studies, no darunavir, primary PI, or tenofovir resistance-associated mutations (RAMs) were observed in HIV-1 viruses of 1,125 participants receiving D/C/F/TAF or 629 receiving boosted darunavir plus emtricitabine/tenofovir-disoproxil-fumarate. In AMBER, the nucleos(t)ide analog reverse transcriptase inhibitor (N(t)RTI) RAM M184I/V was identified in HIV-1 of one participant during D/C/F/TAF treatment. M184V was detected pretreatment as a minority variant (9%). In EMERALD, in participants with prior VF and genoarchive data (N = 140; 98 D/C/F/TAF and 42 control), 4% had viruses with darunavir RAMs, 38% with emtricitabine RAMs, mainly at position 184 (41% not fully susceptible to emtricitabine), 4% with tenofovir RAMs, and 21% ≥ 3 thymidine analog-associated mutations (24% not fully susceptible to tenofovir) detected at screening. All achieved VL <50 copies/mL at week 48 or prior discontinuation. D/C/F/TAF has a high genetic barrier to resistance; no darunavir, primary PI, or tenofovir RAMs were observed through 48 weeks in AMBER and EMERALD. Only one postbaseline M184I/V RAM was observed in HIV-1 of an AMBER participant. In EMERALD, baseline archived RAMs to darunavir, emtricitabine, and tenofovir in participants with prior VF did not preclude virologic response.

Abstract
Management of the neck in patients with clinical T1N0 oral squamous cell carcinoma (SCC) is controversial. The aim of this study was to report the health-related quality of life (HRQoL) in a consecutive group of patients with stage 1 disease at a time closest to two years after primary surgery. Of 216 patients treated between 2007 and 2012 (after excluding early death and regional recurrence), 195 were eligible. HRQoL was measured using the University of Washington quality of life questionnaire version 4. The overall response rate was 65% (126/195). HRQoL outcomes were good, but compared with patients in the wait and watch group, those who had selective neck dissection (SND) had more problems regarding appearance (14% compared with 1%, p=0.008) and pain (19% compared with 6%, p=0.04). Similar trends were seen for shoulder (14% compared with 8%), mood (16% compared with 8%), and speech (5% compared with 1%), and for poorer overall QoL (30% compared with 16%). It is difficult to establish why patients did or did not have neck dissection in a retrospective sample, but it is likely that those who had SND had larger tumours. The findings highlight the impact that SND has on HRQoL in domains such as appearance, pain, speech, swallowing, and chewing. Previous studies on SND have tended to focus on injury to the accessory nerve and shoulder function, but these new data emphasise the need to include other domains in future trials that compare wait and watch, SND, and sentinel lymph node biopsy.

Abstract
A PCR protocol was optimised and validated for the detection of viable Tenacibaculum maritimum cells in salmon skin tissue. Viability conventional (vPCR) and quantitative PCR (v-qPCR) assays both had a limit of detection of 103 CFU mL-1 viable cells. The v-qPCR assay showed a linear quantification over 4 log units. Conventional vPCR showed complete signal suppression when only dead cells were present at concentrations lower than 106 CFU mL-1. While the v-qPCR did not result in complete suppression when only dead cells were present, a method was developed to determine if viable cells were present based on the % Δ in cycle threshold (Ct) value. The procedure was validated for high-throughput processing and an enrichment protocol was validated to reliably detect low concentrations of viable cells both with and without a high background of dead cells. Performing this protocol on naturally infected tissues showed that vPCR and v-qPCR reduced the potential for false positives compared to using conventional PCR and qPCR. The optimised protocol developed for this study provides an efficient, reliable and robust alternative for the detection of viable T. maritimum in skin tissue.

Abstract
BACKGROUND A range of endophenotypes characterise psychosis, however there has been limited work understanding if and how they are inter-related. METHODS This multi-centre study includes 8754 participants: 2212 people with a psychotic disorder, 1487 unaffected relatives of probands, and 5055 healthy controls. We investigated cognition [digit span (N = 3127), block design (N = 5491), and the Rey Auditory Verbal Learning Test (N = 3543)], electrophysiology [P300 amplitude and latency (N = 1102)], and neuroanatomy [lateral ventricular volume (N = 1721)]. We used linear regression to assess the interrelationships between endophenotypes. RESULTS The P300 amplitude and latency were not associated (regression coef. -0.06, 95% CI -0.12 to 0.01, p = 0.060), and P300 amplitude was positively associated with block design (coef. 0.19, 95% CI 0.10-0.28, p 0.38). All the cognitive endophenotypes were associated with each other in the expected directions (all p < 0.001). Lastly, the relationships between pairs of endophenotypes were consistent in all three participant groups, differing for some of the cognitive pairings only in the strengths of the relationships. CONCLUSIONS The P300 amplitude and latency are independent endophenotypes; the former indexing spatial visualisation and working memory, and the latter is hypothesised to index basic processing speed. Individuals with psychotic illnesses, their unaffected relatives, and healthy controls all show similar patterns of associations between endophenotypes, endorsing the theory of a continuum of psychosis liability across the population.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.
