atient groups to ensure equitable healthcare access. Further evaluation of telehealth during a time of fewer public health emergency measures and lower community anxiety is required to fully understand its ongoing role.
The ciliopathies are a wide spectrum of human diseases, which are caused by perturbations in the function of primary cilia. Tooth enamel anomalies are often seen in ciliopathy patients; however, the role of primary cilia in enamel formation remains unclear.
We examined mice with epithelial conditional deletion of the ciliary protein, Ift88, (Ift88
;K14Cre).
Ift88
;K14Cre mice showed premature abrasion in molars. A pattern of enamel rods which is determined at secretory stage, was disorganized in Ift88mutant molars. Many amelogenesis-related molecules expressing at the secretory stage, including amelogenin and ameloblastin, enamelin, showed significant downregulation in Ift88mutant molar tooth germs. Shh signaling is essential for amelogenesis, which was found to be downregulated in Ift88mutant molar at the secretory stage. Application of Shh signaling agonist at the secretory stage partially rescued enamel anomalies in Ift88mutant mice.
Findings in the present study indicate that the function of the primary cilia via Ift88 is critical for the secretory stage of amelogenesis through involving Shh signaling.

Physical and natural environments might strongly influence mental health and well-being. Many studies have examined this relationship in urban environments, with fewer focused on rural settings. The aim of this systematic review was to synthesise quantitative evidence for the relationship between environmental factors (drought, climate and extreme weather events, land use/environmental degradation, green space/vegetation, engagement in natural resource management activities) and mental health or well-being in rural areas.
Following a systematic search of three databases (PsycINFO, MEDLINE and Web of Science), 4368 articles were identified, of which 28 met eligibility criteria for inclusion in the review.
Poorer mental health and well-being was typically found to have an association with extreme climate or weather events and environmental degradation. The observed relationships were largely assessed at area-wide or community levels.
Studies examining the relationship between the environmental conditionreas, there remain considerable gaps in our knowledge of how rural environments influence mental health and well-being.Recently, nanostructured carbon-based soft bioelectronics and biosensors have received tremendous attention due to their outstanding physical and chemical properties. The ultrahigh specific surface area, high flexibility, lightweight, high electrical conductivity, and biocompatibility of 1D and 2D nanocarbons, such as carbon nanotubes (CNT) and graphene, are advantageous for bioelectronics applications. These materials improve human life by delivering therapeutic advancements in gene, tumor, chemo, photothermal, immune, radio, and precision therapies. They are also utilized in biosensing platforms, including optical and electrochemical biosensors to detect cholesterol, glucose, pathogenic bacteria (e. g., coronavirus), and avian leucosis virus. This review summarizes the most recent advancements in bioelectronics and biosensors by exploiting the outstanding characteristics of nanocarbon materials. The synthesis and biocompatibility of nanocarbon materials are briefly discussed. In the following sections, applications of graphene and CNTs for different therapies and biosensing are elaborated. Finally, the key challenges and future perspectives of nanocarbon materials for biomedical applications are highlighted.The synthesis of enantiopure chiral amines from racemic alcohols is a key transformation in the chemical industry, e. g., in the production of active pharmaceutical ingredients (APIs). However, this reaction remains challenging. In this work, we propose a one-pot enzymatic cascade for the direct conversion of a racemic alcohol into either (S)- or (R)-enantiomers of the corresponding amine, with in-situ cofactor recycling. This enzymatic cascade consists of two enantio-complementary alcohol dehydrogenases, both NADH and NADPH oxidase for in-situ recycling of NAD(P)+ cofactors, and either (S)- or (R)-enantioselective transaminase. This cell-free biocatalytic system has been successfully applied to the conversion of racemic 4-phenyl-2-butanol into the high value (S)- or (R)-enantiomers of the amine reaching good (73 % (S)) and excellent (>99 % (R)) enantioselectivities.Azide-modified nucleosides are important building blocks for RNA and DNA functionalization by click chemistry based on azide-alkyne cycloaddition. This has put demand on synthetic chemistry to develop approaches for the preparation of azide-modified nucleoside derivatives. We review here the available methods for the synthesis of various nucleosides decorated with azido groups at the sugar residue or nucleobase, their incorporation into oligonucleotides and cellular RNAs, and their application in azide-alkyne cycloadditions for labelling and functionalization.
Acute thrombotic thrombocytopenic purpura (TTP) is a life-threatening emergency and plasma exchange (PEX) is the initial treatment shown to reduce acute mortality.
To compare current practice in the United Kingdom (UK) against the standards set out in the 2012 British Society of Haematology guideline, and to better understand the issues affecting prompt initiation of PEX.
The trainee research network HaemSTAR conducted a retrospective nationwide review of adults presenting to UK hospitals with a first episode of acute TTP.
Data on 148 patients treated at 80 UK hospitals between 2014 and 2019 demonstrated that 64.8% of patients received PEX within 24h. Diagnostic uncertainty was the most commonly cited reason for delayed treatment. Conversely, a shorter time to PEX occurred in patients who had red cell fragments or severe thrombocytopenia identified on their first complete blood count. Availability of on-site PEX was associated with a greater proportion of patients receiving PEX within 8h compared to patients transferred, but by 24h there was no difference between the two groups and two-thirds of all patients had received their first PEX. The mortality rate for patients that received PEX was 9.2%, with 27.8% of deaths linked to delayed treatment initiation.
This is the first multi-center evaluation of treatment delays in acute TTP and it will inform targeted pathways to improve prompt access to life-saving intervention.

More than 500,000 dementia cases can be estimated among migrants living in Europe. There is the need to collect "real world" data on the preparedness of healthcare services to support the inclusion of migrants in the public health response to dementia. The present study aimed (i) to estimate the number of migrants referred to Italian memory clinics (Centers for Cognitive Disorders and Dementia [CCDDs]) and (ii) to identify possible barriers and resources for the provision of diversity-sensitive care.
A survey of all Italian CCDDs was conducted between December 2020 and April 2021. An online questionnaire was developed to obtain information on the number of migrants referred to Italian CCDDs in 2019, the challenges encountered in the diagnostic approach, and possible facilitators in the provision of care.
Overall, 343 of the 570 contacted CCDDs completed the survey questionnaire (response rate 60.2%). Nearly 4527 migrants were referred to these services in 2019. Migrants accounted for a median 1.1% (IQR 0.9%-2.8%) of overall CCDD referrals. More than one-third of respondents reported that the number of migrants referred to their facilities had increased in the last 5years. The overall quality of the migrants' cognitive assessment was deemed to be very poor or insufficient in most cases. A minority of CCDDs had translated information material on dementia and reported the possibility to contact cultural mediators and interpreters.
A relevant number of migrants are being referred to Italian CCDDs that are still not adequately prepared to deliver diversity-sensitive care and support.

Neurosarcoidosis can affect all parts of the nervous system of which myelitis is relatively frequent. The aim of this study was to describe clinical characteristics, treatment and prognosis of patients with myelitis attributable to neurosarcoidosis.
We performed a retrospective cohort study and a systematic review and meta-analysis of neurosarcoidosis-associated myelitis.
Myelitis was identified in 41 of 153 (27%) neurosarcoidosis patients seen at our clinic from 2015 to 2020. Classification of neurosarcoidosis was definite in three (7%), probable in 29 (71%) and possible in nine patients (22%). The median (interquartile range) age at onset was 49(41-53) years and 20 of the patients were female (49%). The presenting symptoms included muscle weakness in 31 of 41 patients (78%), sensory loss in 35 (88%) and micturition abnormalities in 30 (75%). Spinal magnetic resonance imaging showed longitudinally extensive myelitis in 27 of 36 patients (75%) and cerebrospinal fluid examination showed an elevated leukombulation occurred frequently.
To determine the contextual factors influencing research and research capacity building in rural health settings.
Qualitative study using semi-structured telephone interviews to collect data regarding health professionals' research education and capacity building. Analysis involved inductive coding using Braun and Clark's thematic analysis; and deductive mapping to the Consolidated Framework for Implementation Research (CFIR).
Victorian rural health services and university campuses.
Twenty senior rural health managers, academics and/or research coordinators. Participants had at least three years' experience in rural public health, health-related research or health education settings.
Contextual factors influencing the operationalisation and prioritisation of research capacity building in rural health services.
Findings reflected the CFIR domains and constructs intervention characteristics (relative advantage); outer setting (cosmopolitanism, external policies and incentives); inner setting (implemutcomes in rural areas requires a strong culture of research and research capacity building in rural health services. Low levels of rural research funding, chronic workforce shortages and the tension between undertaking research and delivering health care, all significantly impact the operationalisation and prioritisation of research capacity building in rural health services. Effective policy and investment addressing these contextual factors is crucial for the success of research capacity building in rural health services.
