The impact of parent history of severe mental illness on schizophrenia outcomes: results from the real-world FACE-SZ cohort.

Parent history of severe mental illness (PHSMI) may have long-term consequences in adult offspring due to genetic and early environmental factors in preliminary studies. To compare the outcomes associated in subjects with PHSMI to those in patients without PHSMI. The participants with schizophrenia and schizoaffective disorders were recruited in the ongoing FACE-SZ cohort at a national level (10 expert centers) and evaluated with a 1-day-long standardized battery of clinician-rated scales and patient-reported outcomes. PHSMI was defined as history of schizophrenia or bipolar disorders in at least one parent and was included as explanatory variable in multivariate models. Of the 724 included patients, 78 (10.7%) subjects were classified in the PHSMI group. In multivariate analyses, PHSMI patients had a better insight into schizophrenia and the need for treatment and reported more often childhood trauma history compared to patients without PHSMI. More specifically, those with paternal history of SMI reported more severe outcomes (increased childhood physical and emotional abuses, comorbid major depression and psychiatric hospitalizations). PHSMI is associated with increased risk of childhood trauma, major depressive disorder and psychiatric hospitalization and better insight in individuals with schizophrenia. Specific public health prevention programs for parents with SMI should be developed to help protect children from pejorative psychiatric outcomes. PHSMI may also explain in part the association between better insight and increased depression in schizophrenia.

Early-life factors associated with increased risk of disability pension in the national real-world schizophrenia FACE-SZ cohort study.

Among severe psychiatric disorders, schizophrenia has one of the highest impacts on professional and personal functioning with important indirect costs including disability pension allowance for the patients with the more severe forms of schizophrenia. To explore early-life factors associated with disability pension in schizophrenia. 916 patients were consecutively recruited at a national level in 10 expert centers and received a comprehensive standardized evaluation. Their disability pension status and early-life variables were reported from medical records and validated scales. Eight factors were explored: age, male sex, parental history of severe mental illness, childhood trauma exposure, education level, childhood ADHD, early age at schizophrenia onset and duration of untreated psychosis. 739 (80.7%) participants received a disability pension. In the multivariate model, early age at schizophrenia onset and low education level were associated with disability pension independently of age and sex while no significant association was found for parent history of severe mental illness, childhood trauma, childhood ADHD or duration of untreated psychosis. Low education level and early age at schizophrenia onset seem the best predictors of increased risk of disability pension in schizophrenia.

Addition of low-dose liraglutide to insulin therapy is useful for glycaemic control during the peri-operative period: effect of glucagon-like peptide-1 receptor agonist therapy on glycaemic control in patients undergoing cardiac surgery (GLOLIA study).

AIM: To test the hypothesis that the addition of a glucagon-like peptide-1 receptor agonist that can decrease glucose levels without increasing the hypoglycaemia risk will achieve appropriate glycaemic control during the peri-operative period. METHODS: We studied 70 people with Type 2 diabetes who underwent elective cardiac surgery. Participants were randomized to either an insulin-alone or an insulin plus liraglutide 0.6 mg/day group. We evaluated average M values, which indicated the proximity index of the target glucose level from day 1 to day 10. RESULTS: The average M value in the liraglutide plus insulin group was significantly lower than that in the insulin-alone group (liraglutide plus insulin 5.8 vs insulin-alone 12.3; P < 0.001). The frequency of insulin dose modification in the liraglutide plus insulin group was significantly lower than that in the insulin-alone group (odds ratio 0.19, 95% CI 0.08-0.49; P < 0.001). The frequency of hypoglycaemia in the liraglutide plus insulin group tended to be lower than that in the insulin-alone group (odds ratio 0.57, 95% CI 0.15-2.23; P = 0.21). CONCLUSIONS: The results of this study showed that the addition of low-dose liraglutide to insulin achieved lower M values than insulin alone, suggesting that the addition of low-dose liraglutide may achieve better glycaemic control during the peri-operative period.

Longitudinal changes in 18 F-THK5351 positron emission tomography in corticobasal syndrome.

BACKGROUND AND PURPOSE: Corticobasal syndrome (CBS) is pathologically characterized by tau deposits in neuronal and glial cells and by reactive astrogliosis. In several neurodegenerative disorders, 18 F-THK5351 has been observed to bind to reactive astrocytes expressing monoamine oxidase B. In this study, the aim was to investigate the progression of disease-related pathology in the brains of patients with CBS using positron emission tomography with 18 F-THK5351. METHODS: Baseline and 1-year follow-up imaging were acquired using magnetic resonance imaging and positron emission tomography with 18 F-THK5351 in 10 subjects: five patients with CBS and five age-matched normal controls (NCs). RESULTS: The 1-year follow-up scan images revealed that 18 F-THK5351 retention had significantly increased in the superior parietal gyrus of the patients with CBS compared with the NCs. The median increases in 18 F-THK5351 accumulation in the patients with CBS were 6.53% in the superior parietal gyrus, 4.34% in the precentral gyrus and 4.33% in the postcentral gyrus. In contrast, there was no significant increase in the regional 18 F-THK5351 retention in the NCs. CONCLUSIONS: Longitudinal increases in 18 F-THK5351 binding can be detected over a short interval in the cortical sites of patients with CBS. A monoamine oxidase B binding radiotracer could be useful in monitoring the progression of astrogliosis in CBS.

Administration of platelet concentrates suspended in bicarbonated Ringer's solution in children who had platelet transfusion reactions.

BACKGROUND AND OBJECTIVES: Adverse reactions to platelet transfusions are a problem. Children with primary haematological and malignant diseases may experience allergic transfusion reactions (ATRs) to platelet concentrates (PCs), which can be prevented by giving washed PCs. A new platelet additive solution, using bicarbonated Ringer's solution and acid-citrate-dextrose formula A (BRS-A), may be better for platelet washing and storage, but clinical data are scarce. MATERIALS AND METHODS: A retrospective cohort study for consecutive cases was performed between 2013 and 2017. For 24 months, we transfused washed PCs containing BRS-A to children with primary haematological and malignant diseases and previous adverse reactions. Patients transfused with conventional PCs (containing residual plasma) were assigned as controls, and results were compared in terms of frequency of ATRs, corrected count increment (CCI) and occurrence of bleeding. We also studied children transfused with PCs washed by a different system as historical controls. RESULTS: Thirty-two patients received 377 conventional PC transfusions. ATRs occurred in 12 (37·5%) patients from transfused with 18 (4·8%) bags. Thirteen patients, who experienced reactions to regular PCs in plasma, then received 119 transfusion bags of washed PCs containing BRS-A, and none had ATRs to washed PCs containing BRS-A. Before study period, six patients transfused 137 classical washed PCs with different platelet additive solution, under same indication, ATRs occurred in one (16·7%) patient from transfused with one (0·7%) bags. CCIs (24 h) in were lower with classical washed PCs (1·26 ± 0·54) compared to regular PCs in plasma (2·07 ± 0·76) (P < 0·001), but there was no difference between washed PCs containing BRS-A (2·14 ± 0·77) and regular PCs (2·21 ± 0·79) (P = 0·769), and we saw no post-transfusion bleeding. CONCLUSION: Washed PCs containing BRS-A appear to prevent ATRs without loss of transfusion efficacy in children with primary haematological and malignant diseases. Their efficacy should be further evaluated through larger prospective clinical trials.

Key factors for school health policy implementation in Thailand.

Thailand formulated a National School Health Policy (NSHP) in 1998, and it has been widely implemented but has not been evaluated. This case study aimed to identify factors that have influenced the implementation of NSHP in Thailand. For this purpose, we conducted a document review and key informant interviews. We selected key interviewees, from NSHP implementers at national, provincial and school levels in four geographical areas. We adopted a content analysis method, using a framework of 12 influential components of successful policy implementation and triangular policy framework. This study showed that NSHP was well-disseminated and implemented at whole country. We identified seven positive factors influencing NSHP implementation, namely matching with ongoing educational strategy, competition and encouragement by an awarding system, sustainable human capacity building at school level, participation of multiple stakeholders, sufficient understanding and acceptance of school health concepts, sharing information and collaboration among schools in the same clusters and functional fund raising activities. In addition, we identified three negative factors, namely lack of institutional sustainability, vague role of provincial officers and diverse health problems among Thai children. The government should clarify the role of provincial level and set up institutionalized capacity-building system as measures to strengthen monitoring and evaluation activities.

Isotopic Shift of Atom-Dimer Efimov Resonances in K-Rb Mixtures: Critical Effect of Multichannel Feshbach Physics.

Multichannel Efimov physics is investigated in ultracold heteronuclear admixtures of K and Rb atoms. We observe a shift in the scattering length where the first atom-dimer resonance appears in the ^{41}K-^{87}Rb system relative to the position of the previously observed atom-dimer resonance in the ^{40}K-^{87}Rb system. This shift is well explained by our calculations with a three-body model including van der Waals interactions, and, more importantly, multichannel spinor physics. With only minor differences in the atomic masses of the admixtures, the shift in the atom-dimer resonance positions can be cleanly ascribed to the isolated and overlapping Feshbach resonances in the ^{40}K-^{87}Rb and ^{41}K-^{87}Rb systems, respectively. Our study demonstrates the role of multichannel Feshbach physics in determining Efimov resonances in heteronuclear three-body systems.

Patterns of trematode infections of Opisthorchis viverrini (Opisthorchiidae) and Haplorchis taichui (Heterophyidae) in human populations from two villages in Savannakhet Province, Lao PDR.

The liver fluke, Opisthorchis viverrini, and the minute intestinal fluke, Haplorchis taichui, are prevalent in many Asian countries. This study analysed the patterns of infections of O. viverrini and H. taichui in Lahanam and Thakhamlien villages (Savannakhet Province, Lao PDR), in two cross-sectional investigations. Out of a total of 207 human participants, post-anthelmintic treatment positivity rates for expelled worms were 170 (82.1%) for H. taichui and 65 (31.4%) for O. viverrini. Both these species co-exist in the study villages. When each parasite was analysed separately, H. taichui infections reached a plateau among people aged >20 years. Opisthorchis viverrini infection rates were highest in the age group 21-30 years, with decreasing infection rates after the age of 30. Our findings indicated that fish-borne trematode infections were more prevalent among adults. Fish, common intermediate hosts, were acquired in the study area for analysis. The examination of 35 species of fish as intermediate hosts found O. viverrini metacercariae in only six species, and these were found mostly during the month of November. Many farmers who live on the rice fields obtain their food from their immediate environment, including these intermediate-host fish, potentially putting them at greater risk of O. viverrini infection. By contrast, H. taichui metacercariae were found in three species of fish obtained from the market, meaning that anyone could consume them and become infected. If people who work in rice fields limit the species of fish they consume, or avoid consuming raw fish during the month of November, they may reduce their risk of O. viverrini infection.

Intravenous thrombolysis for patients with reverse magnetic resonance angiography and diffusion-weighted imaging mismatch: SAMURAI and NCVC rt-PA Registries.

BACKGROUND AND PURPOSE: The characteristics of reverse magnetic resonance angiography and diffusion-weighted imaging (MRA-DWI) mismatch (RMM), defined as a large DWI lesion in the absence of major artery occlusion (MAO), remain unknown, especially in patients treated with intravenous recombinant tissue plasminogen activator (rt-PA). METHODS: Patients with stroke in the middle cerebral artery territory were included. Early ischaemic changes (EIC) were assessed with the Alberta Stroke Program Early CT Score on DWI (DWI-ASPECTS). All patients were divided into four groups based on the presence of MAO and a DWI-ASPECTS cut-off value of <7. RMM was defined as DWI-ASPECTS <7 without MAO. Clinical characteristics, symptomatic intracerebral hemorrhage (sICH) and favorable functional outcome (modified Rankin Scale score 0-2) at 90 days were compared amongst the four groups. RESULTS: Of the 486 patients enrolled (167 women, median age 74 years, median initial National Institutes of Health Stroke Scale score 13), reverse MRA-DWI mismatch was observed in 24 (5%). Of the clinical characteristics, cardioembolism was the only factor that was independently associated with RMM [odds ratio (OR) 5.49, 95% confidence interval (CI) 1.25-24.1]. Multivariable analyses revealed that patients with RMM more commonly had sICH than those with DWI-ASPECTS ≥ 7 irrespective of the presence (OR 5.44, 95% CI 1.13-26.1) or absence (13.1, 2.07-83.3) of MAO, and they had a more favorable functional outcome than those with DWI-ASPECTS < 7 plus MAO (7.45, 2.39-23.2). CONCLUSION: RMM was observed in 5% of patients treated with rt-PA and associated with cardioembolism. Patients with RMM may benefit from thrombolysis compared with those with EIC with MAO, although increment in the rate of sICH is a concern.

Evaluation of automated 2D-3D image overlay system utilizing subtraction of bone marrow image for EVAR: feasibility study.

OBJECTIVE: To evaluate the automated 2D-3D image overlay system ("3D Roadmap") for use during endovascular aneurysm repair (EVAR) in the hybrid operating theater. METHODS: Datasets of preoperative CT images were modified to subtract dense bone marrow to improve the visualization of vasculature on the overlaid image, and allow for accurate navigation of the endovascular devices. The 3D-CT overlay image was registered on the 2D fluoroscopy image to mark the iliac crest and lumbar vertebrae on both images as landmarks. RESULTS: Arteriography was performed only twice to confirm the precision of the position of renal artery and the final evaluation. Twenty patients underwent EVAR with Medtronic Endurant, Gore Excluder, or COOK Zenith using "3D Roadmap". The origin of the renal artery and iliac bifurcation were registered with complete accuracy in 10 patients (50%). The lower renal artery deviated toward the cranial side less than 3 mm in six patients. In all cases, EVAR was successful, and completed with the volume of contrast material limited to 43.8 ± 3.1 mL. CONCLUSION: "3D Roadmap" was confirmed to be valuable for visualization of vessel origin in a fused image and for reduction of contrast material during EVAR.

Self-assessed approach to improving school health in Niger.

INTRODUCTION: Award schemes and self-evaluation systems have been developed to implement the 'Health-Promoting School (HPS)' concept in European and Asian countries. While there have been many successes in these regions, the implementation of HPS in African countries has been minimal. This study evaluated the impact of a self-evaluation system on school health in Niger. METHODS: A school health activity guide was developed and distributed to 1999 primary schools in the Niger Tahoua region to raise awareness and solve problems related to school health and hygiene. The number of schools that planned or implemented health-related activities, and the budget and implementation status of their activities was compared over 3 years (before, soon after, and 1 year after distribution). Focus group discussions (FGDs) were also conducted targeting Conseillers Pédagogiques (CPs), who supervise primary schools and teachers, primary school principals and members of Comité de Gestion des Etablissement Scolaire (COGES), which is a type of school steering committee. RESULTS: The number of schools planning at least one health-related activity increased from 47% to 79% soon after distribution of the guide (p <0.001).The number of schools implementing activities increased from 44% to 65% one year after distribution (p <0.001). Health-related budget per school also increased after distribution (p <0.0001) and increases were maintained 1 year after the intervention (p=0.8414). Fulfilment or partial fulfilment rates for health-related activities were lower compared with other (non-health) activities in all three years (80%, 77% & 84% in health-related activities vs 88%, 90% & 91% in others; p <0.001, p <0.001, & p=0.004, respectively). Most FGD participants expressed a positive impression of the program and noted the usefulness of the guide. However, some respondents reported difficulties, especially in relation to budget. CONCLUSION: The introduction of a health activity guide for self-assessment was effective in increasing health-related activities in primary schools in Niger, where a simple monitoring system should be introduced to establish the HPS concept.

[Cardiac surgery in patients with cerebrovascular disease].

Cerebral event is the 2nd leading cause of mortality and morbidity after cardiac surgery. Therefore, management of cerebrovascular disease is essential to improve the outcome. We reviewed the literatures and cases in our institute to present the current strategy for these patients. Firstly, for the patients in high risk of stroke, if patients undergo coronary artery bypass grafting (CABG), off-pump CABG (OPCAB) with aorta non-touch technique is recommended. We experienced no intraoperative stroke in our recent consecutive 1,000 cases. If patients require cardiopulmonary bypass, keeping blood pressure high during bypass may prevent local hypoperfusion in brain. Second, for the patients having carotid artery disease, the team approach with neurologists is essential to determine to precede either of cardiac surgery or carotid endoarterectomy. Because preceding carotid endoarterectomy gives the best result to prevent stroke, these patients had better have carotid endoarterectomy first, unless there is indication of urgent cardiac surgery. Third, for the patients with active endocarditis, early indication of surgery is recently recommended, unless patients have intracranial hemorrhage. Recent magnetic resonance imaging (MRI) examination revealed more than 60% of patients have stroke regardless of size, therefore, team approach with neurologists is important to decide the timing of the surgery. Team approach and correct selection of procedural technique are important to prevent cerebrovascular events during cardiac surgery.

Narrow-linewidth light source for a coherent Raman transfer of ultracold molecules.

We describe a tunable two-color CW light source sufficient for realizing a coherent Raman transfer between two molecular states that are more than 0.5 eV (120 THz) apart. The simultaneous frequency stabilization of 901 nm and 655 nm light was achieved by locking diode lasers to a single ultralow expansion cavity with dual wavelengths coating. By utilizing offset-locking and optical phase-locked loop (OPLL), we ensured a large mode-hop free tuning range (> 2 GHz). The obtained short term linewidth (<10 Hz) and the linear drift of frequency (65 mHz/s) were both sufficient to eliminate the influence of laser linewidths on the efficiency of coherent Raman transition.

Redefining peripheral inflammation signature in schizophrenia based on the real-world FACE-SZ cohort.

BACKGROUND: Peripheral inflammation is associated with impaired prognosis in schizophrenia (SZ). Highly sensitive C-reactive protein (hs-CRP) is the most used inflammatory biomarker in daily practice. However, no consensual cut-off has been determined to date to discriminate patients with peripheral inflammation from those without. AIMS: To determine if patients with peripheral inflammation between 1 and 3 mg/L had poorer outcomes compared to those with undetectable CRP (<1 mg/L). METHOD: Consecutive participants of the FACE-SZ cohort with a hs-CRP < 3 mg/L were included in 10 expert academic centers with a national geographical distribution between 2010 and 2018. Potential sources of inflammation, socio-demographics, illness characteristics, current illness severity, functioning and quality of life and were reported following the FACE-SZ standardized protocol. RESULTS: 580 patients were included, of whom 226 (39%) were identified with low-grade inflammation defined by a hs-CRP between 1 and 3 mg/L. Overweight and lack of dental care were identified as potential sources of inflammation. After adjustment for these factors, patients with inflammation had more severe psychotic, depressive and aggressive symptomatology and impaired functioning compared to the patients with undetectable hs-CRP. No association with tobacco smoking or physical activity level has been found. CONCLUSIONS: Patients with schizophrenia with hs-CRP level between 1 and 3 mg/L should be considered at risk for inflammation-associated disorders. Lowering weight and increasing dental care may be useful strategies to limit the sources of peripheral inflammation. Hs-CRP > 1 mg/L is a reliable marker to detect peripheral inflammation in patients with schizophrenia.

Bombyx mori Ras proteins BmRas1, BmRas2 and BmRas3 are neither farnesylated nor palmitoylated but are geranylgeranylated.

The lipid modifications which occur on Bombyx mori Ras proteins BmRas1, BmRas2 and BmRas3 were studied by metabolic labelling in an insect cell-free protein synthesis system and in a baculovirus expression system, using specific inhibitors of protein prenylation and protein palmitoylation. In addition, the subcellular localization of BmRas proteins was examined using EGFP fusion proteins of constitutively active forms of BmRas proteins transiently expressed in Sf9 cells. As a result, it was revealed that the three B. mori Ras proteins BmRas1, BmRas2 and BmRas3 are neither farnesylated nor palmitoylated but are geranylgeranylated for localization to the plasma membrane of insect cells. Thus, the mechanism of membrane binding of insect Ras proteins is quite different from that reported for mammalian Ras proteins.

Coherent transfer of photoassociated molecules into the rovibrational ground state.

We report on the direct conversion of laser-cooled 41K and 87Rb atoms into ultracold 41K87Rb molecules in the rovibrational ground state via photoassociation followed by stimulated Raman adiabatic passage. High-resolution spectroscopy based on the coherent transfer revealed the hyperfine structure of weakly bound molecules in an unexplored region. Our results show that a rovibrationally pure sample of ultracold ground-state molecules is achieved via the all-optical association of laser-cooled atoms, opening possibilities to coherently manipulate a wide variety of molecules.

[Tracheostenosis caused by blunt thoracic trauma].

Blunt thoracic trauma rarely implicate retropharyngeal hematoma obstructing trachea. 85-year-old woman being struck on her cheek and anterior chest, visited our emergency room. She was nearly suffocated following stridor and dyspnea. Tracheal intubation relieved her dyspnea Chest computed tomography (CT) showed retropharyngeal hematoma obstructing trachea. 5 days conservative management reduced the hematoma and tracheal tube was extubated through an uneventful course.

Measurement of the variation of electron-to-proton mass ratio using ultracold molecules produced from laser-cooled atoms.

Experimental techniques to manipulate cold molecules have seen great development in recent years. The precision measurements of cold molecules are expected to give insights into fundamental physics. Here we use a rovibrationally pure sample of ultracold KRb molecules to improve the measurement on the stability of electron-to-proton mass ratio [Formula: see text]. The measurement is based upon a large sensitivity coefficient of the molecular spectroscopy, which utilizes a transition between a nearly degenerate pair of vibrational levels each associated with a different electronic potential. Observed limit on temporal variation of µ is [Formula: see text], which is better by a factor of five compared with the most stringent laboratory molecular limits to date. Further improvements should be straightforward, because our measurement was only limited by statistical errors.

Current-feedback-stabilized laser system for quantum simulation experiments using Yb clock transition at 578 nm.

We developed a laser system for the spectroscopy of the clock transition in ytterbium (Yb) atoms at 578 nm based on an interference-filter stabilized external-cavity diode laser (IFDL) emitting at 1156 nm. Owing to the improved frequency-to-current response of the laser-diode chip and the less sensitivity of the IFDL to mechanical perturbations, we succeeded in stabilizing the frequency to a high-finesse ultra-low-expansion glass cavity with a simple current feedback system. Using this laser system, we performed high-resolution clock spectroscopy of Yb and found that the linewidth of the stabilized laser was less than 320 Hz.

Homologous recombination repair is regulated by domains at the N- and C-terminus of NBS1 and is dissociated with ATM functions.

The proteins responsible for radiation sensitive disorders, NBS1, kinase ataxia-telangiectasia-(A-T)-mutated (ATM) and MRE11, interact through the C-terminus of NBS1 in response to the generation of DNA double-strand breaks (DSBs) and are all implicated in checkpoint regulation and DSB repair, such as homologous recombination (HR). We measured the ability of several NBS1 mutant clones and A-T cells to regulate HR repair using the DR-GFP or SCneo systems. ATM deficiency did not reduce the HR repair frequency of an induced DSB, and it was confirmed by findings that HR frequencies are only slightly affected by deletion of ATM-binding site at the extreme C-terminus of NBS1. In contrast, The HR-regulating ability is dramatically reduced by deletion of the MRE11-binding domain at the C-terminus of NBS1 and markedly inhibited by mutations in the FHA/BRCT domains at the N-terminus. This impaired capability in HR is consistent with a failure to observe MRE11 foci formation. Furthermore, normal HR using sister chromatid was completely inhibited by the absence of FHA/BRCT domains. These results suggested that the N- and C-terminal domains of NBS1 are the major regulatory domains for HR pathways, very likely through the recruitment and retention of the MRE11 nuclease to DSB sites in an ATM-independent fashion.
