Oculocutaneous albinism (OCA) is a group of heterogeneous genetic disorders characterized by abnormal melanin synthesis in the hair, skin, and eyes. OCA exhibits obvious genetic and phenotypic heterogeneity. Molecular diagnosis of causal genes can be of help in the classification of OCA subtypes and the study of OCA pathogenesis． METHODS In this study, Sanger sequencing and whole exome sequencing were used to genetically diagnose 20 nonconsanguineous Chinese OCA patients. In addition, prenatal diagnosis was provided to six OCA families.

Variants of TYR, OCA2, and HPS1 were detected in 85%, 10%, and 5% of affected patients, respectively. A total of 21 distinct variants of these three genes were identified. Exons 1 and 2 were the hotspot regions of the TYR variants, and c.895C>A and c.896G>A were the hotspot variants. We also found seven novel variants c.731G>A, c.741C>A, c.867C>A, and c.1037-2A>T in TYR, c.695dupT and c.1054A>G in OCA2, and c.9C>A in HPS1. Genetic tests on six fetuses revealed three carrier fetuses, two normal fetuses, and one affected fetus. The follow-up results after birth were consistent with the results of prenatal diagnosis (one fetus terminated during pregnancy was not followed up).

This study expands our understanding of the genotypic spectrum of the Chinese OCA population. see more The findings indicate that prenatal diagnosis can provide important information for genetic counseling.

Phantom eye syndrome (PES) is an underestimated complication of eye amputation (EA) characterized by phantom eye pain (PEP), phantom visions and/or phantom sensations. The aim of this study was to assess PEP prevalence, features, risk factors, social and psychological consequences and associated quality of life.

A questionnaire study was conducted in three oculoplastic departments between April 2016 and July 2017. Patients >18years who had undergone EA ≥3months earlier were included and asked to complete a prestamped questionnaire. Patient's characteristics, preoperative, surgical and postoperative data were collected.

Of the 185 questionnaires given, 115 (62%) were returned for analysis. Hundred patients with a mean age of 65.1years (29-92; SD=13.0) were included. Eye amputation (EA) indications were uveal melanoma (n=24, 24%), trauma (n=20, 20%), retinal detachment (n=20, 20%), glaucoma (n=14, 14%) and endophthalmitis (n=12, 12%). Forty-seven (47%), 30 (30%) and 38 (38%) patients experienced PEP, phantom visions and phantom sensations, respectively. Anxiety and depression [Hospital Anxiety Depression scale (HADS) score ≥8 for both] were diagnosed in 34 (34%) and 42 (42%) patients, respectively. The mean EQ-5D-3L and EQ-5D visual analogue scale scores were 0.8 (0.06-1; SD=0.2) and 68 (0-100; SD=22), respectively. Preoperative eye pain (p=0.031), glaucoma (p=0.027), postoperative anxiety with HADS score ≥8 (p=0.012) and ≥11 (p=0.014), aesthetic discomfort (p=0.002) and EQ-5D-3L score <0.8 (p<0.001) were significantly associated with PEP in the univariate analysis. In the multivariate analysis, only anxiety (HADS score ≥8) was significantly associated with PEP (p=0.009).

Phantom eye pain (PEP) is a common complication of EA strongly associated with postoperative anxiety.

The arylamine moieties were installed at the 6 position of 2,2'-bipyridine (bpy) to generate a family of isomers in which the primary amine is located at the ortho- (1-Mn), meta- (2-Mn), or para-site (3-Mn) of the aniline ring. The proximity of the second-sphere functionality to the active site is a critical factor in determining catalytic performance. Catalyst 1-Mn, possessing the shortest distance between the amine and the active site, significantly outperformed the rest of the series and exhibited a 9-fold improvement in turnover frequency relative to parent catalyst Mn(bpy)(CO)3 Br (901 vs. 102 s-1 , respectively) at 150 mV lower overpotential. The electrocatalysts operated with high faradaic efficiencies (≥70 %) for CO evolution using trifluoroethanol as a proton source. Notably, under photocatalytic conditions, a concentration-dependent shift in product selectivity from CO (at high [catalyst]) to HCO2 H (at low [catalyst]) was observed with turnover numbers up to 4760 for formic acid and high selectivities for reduced carbon products.The ongoing coronavirus disease 2019 (COVID-19) crisis caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a large-scale pandemic that is afflicting millions of individuals in over 200 countries. The clinical spectrum caused by SARS-CoV-2 infections can range from asymptomatic infection to mild undifferentiated febrile illness to severe respiratory disease with multiple complications. Elderly patients (aged 60 and above) with comorbidities such as cardiovascular diseases and diabetes mellitus appear to be at highest risk of a severe disease outcome. To protect against pulmonary immunopathology caused by SARS-CoV-2 infection, the host primarily depends on two distinct defense strategies resistance and disease tolerance. Resistance is the ability of the host to suppress and eliminate incoming viruses. By contrast, disease tolerance refers to host responses that promote host health regardless of their impact on viral replication. Disruption of either resistance or disease tolerance mechanisms or both could underpin predisposition to elevated risk of severe disease during viral infection. Aging can disrupt host resistance and disease tolerance by compromising immune functions, weakening of the unfolded protein response, progressive mitochondrial dysfunction, and altering metabolic processes. A comprehensive understanding of the molecular mechanisms underlying declining host defense in elderly individuals could thus pave the way to provide new opportunities and approaches for the treatment of severe COVID-19.This study reports the impacts of seasonal ammonia load changes and biofilm age on the quantity of biomass and on the prevalence of ammonia- and nitrite-metabolizing organisms within a submerged attached-growth reactor (SAGR™) following lagoon treatment. Ammonia (NH3 ) loadings (0.12-3.17 kg/d) in the primary SAGR were measured over 223 days from May to December in 2017. Adjustment of the wastewater flow path on September 1 successfully increased NH3 loading to the primary SAGR, which subsequently caused reactor biomass to increase. The NH3 removal rate in October (0.5 kg/d) was greater than rates in June and July (0.3 and 0.2 kg/d) despite a water temperature decrease from >24 to 15.6°C. This elevated removal rate in October, and the sustained removal rate in December (0.4 kg/d, 5.3°C) were associated with a measured increase in microbial biomass. The relative abundance of the anammox organism C. Brocadia was 5 times greater in the mature biofilm after 686 days of growth, and the genus Pseudomonas increased sevenfold. The presence of Pseudomonas, which contains denitrifying species, and anammox suggests a high potential for removal of total nitrogen in SAGRs. PRACTITIONER POINTS Pseudomonas prevalence and the presence of anammox suggest a high potential for total nitrogen removal in mature SAGR biofilms. The abundance of the anammox microorganism C. Brocadia was greater after 686 days of biofilm growth compared with 33 days. Simple operational changes can increase biomass in the SAGR to maintain, or even increase, NH3 transformation rates during cold weather.

To use participatory action research (PAR) to understand workplace engagement of caregivers in aged residential care (ARC) in New Zealand.

A PAR study was conducted in a 40-bed ARC facility providing rest home- and hospital-level care in rural New Zealand. The four-step study included an advisory group of caregivers (N=6) who co-designed the process. Data were collected via verbatim transcripts of four advisory group meetings, five interviews with staff and field notes over a period of six months. The data were analysed using thematic analysis.

A model was developed to describe factors that encouraged caregivers' engagement in their work. Caregivers were more engaged in their workplace when the influencers of 'Communication', 'Contributing to the workplace' and 'Caring for oneself' were present and when they experienced 'feeling valued', 'being heard' and 'being listened to'.

Factors influencing positive changes in workplace engagement were identified that could be considered when implementing organisational change or service development in other ARC facilities. These factors could potentially increase productivity and quality of care at little cost, as well as improve workplace satisfaction.

Maintaining a balance between T helper 17 (Th17) and regulatory T (Treg) cells are critical for the control of the immunopathogenesis of liver diseases. Here, by using the mouse model of helminth Schistosoma japonicum (S japonicum) infection, we show that the hepatic mRNA levels of P21-activated kinase 1 (PAK1), a key regulator of the actin cytoskeleton, adhesion and cell motility, are significantly increased and associated with the development of liver pathology during S japonicum infection. In addition, PAK1-deficient mice are prone to suppression of Th17 cell responses but increased Treg cells. Furthermore, PAK1 enhances macrophage activation through promoting IRF1 nuclear translocation in an NF-κB-dependent pathway, resulting in promoting Th17 cell differentiation through inducing IL-6 production. These findings highlight the importance of PAK1 in macrophages fate determination and suggest that PAK1/IRF1 axis-dependent immunomodulation can ameliorate certain T cell-based immune pathologies.

The Environmental Determinants of the Diabetes in the Young (TEDDY) study has prospectively followed, from birth, children at increased genetic risk of type 1 diabetes. TEDDY has collected heterogenous data longitudinally to gain insights into the environmental and biological mechanisms driving the progression to persistent islet autoantibodies.

We developed a machine learning model to predict imminent transition to the development of persistent islet autoantibodies based on time-varying metabolomics data integrated with time-invariant risk factors (eg, gestational age). The machine learning was initiated with 221 potential features (85 genetic, 5 environmental, 131 metabolomic) and an ensemble-based feature evaluation was utilized to identify a small set of predictive features that can be interrogated to better understand the pathogenesis leading up to persistent islet autoimmunity.

The final integrative machine learning model included 42 disparate features, returning a cross-validated receiver operating characteristic area under the curve (AUC) of 0.
