The 3rd quantile of 1-hydroxypyrene were also associated with increased odds of emphysema in smokers. Among arsenic and metals, the 4th quantile of cadmium was associated with an increased odds of emphysema in smokers. The 3rd quantile of dimethylarsinic acid (DMA) and 4th quantile of mercury were found to have inverse relationships with emphysema in smokers. Several demographic factors had significant associations with emphysema in smokers.

Urinary PAHs and cadmium were associated with increased odds of emphysema in smokers. DMA and mercury had an inverse association with emphysema in smokers.

The adverse impact of maternal alcohol and nicotine use during the perinatal period on offspring health has been well established, including their associations with adverse cardiovascular health in offspring. However, limited studies examine the impact of other well-known SU utilized during pregnancy on offspring's cardiovascular health. This review summarizes the proposed mechanism of action of four commonly utilized substances cocaine, marijuana, methamphetamine, and opioids, and their cardiovascular impact. Furthermore, we will review the current understanding of the adverse impact of substance use during pregnancy on offspring's cardiovascular system based on existing studies. This review will also highlight possible molecular mechanisms underlying the in-utero adverse programming of offspring's cardiovascular system secondary to SU in pregnancy and address the gaps in current understanding of how SU adversely impacts the developing cardiovascular system of offspring in utero.Humans are exposed to disinfection by-products through oral, inhalation, and dermal routes, during bathing and swimming, potentially causing skin lesions, asthma, and bladder cancer. Nuclear factor E2-related factor 2 (NRF2) is a master regulator of the adaptive antioxidant response via the antioxidant reaction elements (ARE) orchestrating the transcription of a large group of antioxidant and detoxification genes. Here we used an immortalized human keratinocyte model HaCaT cells to investigate NRF2-ARE as a responder and protector in the acute cytotoxicity of seven haloacetonitriles (HANs), including chloroacetonitrile (CAN), bromoacetonitrile (BAN), iodoacetonitrile (IAN), bromochloroacetonitrile (BCAN), dichloroacetonitrile (DCAN), dibromoacetonitrile (DBAN), and trichloroacetonitrile (TCAN) found in drinking water and swimming pools. The rank order of cytotoxicity among the HANs tested was IAN ≈ BAN ˃ DBAN ˃ BCAN ˃ CAN ˃ TCAN ˃ DCAN based on their LC50. The HANs induced intracellular reactive oxygen species accumulation and activated cellular antioxidant responses in concentration- and time-dependent fashions, showing elevated NRF2 protein levels and ARE activity, induction of antioxidant genes, and increased glutathione levels. Additionally, knockdown of NRF2 by lentiviral shRNAs sensitized the HaCaT cells to HANs-induced cytotoxicity, emphasizing a protective role of NRF2 against the cytotoxicity of HANs. These results indicate that HANs cause oxidative stress and activate NRF2-ARE-mediated antioxidant response, which in turn protects the cells from HANs-induced cytotoxicity, highlighting that NRF2-ARE activity could be a sensitive indicator to identify and characterize the oxidative stress induced by HANs and other environmental pollutants.

Genetics plays an important role in progressive supranuclear palsy (PSP) and remains poorly understood. A detailed literature search identified 19 PSP-associated genes MAPT, LRRK2, LRP10, DCTN1, GRN, NPC1, PARK, TARDBP, TBK1, BSN, GBA, STX6, EIF2AK3, MOBP, DUSP10, SLCO1A2, RUNX2, CXCR4, and APOE. To date, genetic studies on PSP have focused on Caucasian population. The gaps in PSP genetic study on East Asian populations need to be filled.

Exon and flanking regions of the PSP-associated genes were sequenced in 104 patients with PSP and 488 healthy controls. Common variant-based association analysis and gene-based association tests of rare variants were performed using PLINK 1.9 and the sequence kernel association test-optimal, respectively. Additionally, the association of APOE and MAPT genotypes with PSP was evaluated. The above association analyses were repeated among probable PSP patients. Finally, PLINK 1.9 was used to test variants associated with the onset age of PSP.

A rare non-pathogenic variant of MAPT (c.425C>T,p.A142V) was detected in a PSP patient. No common variants were significantly associated with PSP. In both the rare-variant and the rare-damaging-variant groups, the combined effect for GBA reached statistical significance (p=1.43×10

, p=4.98×10

). Stem Cells inhibitor The result between APOE, MAPT genotypes and PSP risk were inconsistent across all PSP group and probably PSP group.

The pathogenic variant in MAPT were uncommon in PSP patients. Moreover, GBA gene was likely to increase the risk of PSP, and GBA-associated diseases were beyond α-synucleinopathies. The association between APOE, MAPT and PSP is still unclear among the non-Caucasian population.

Although telemedicine was a nascent means of health care delivery before COVID-19, it now is one of the principal means for doing so today, and it is likely to remain so. Whether this will happen may depend in part on continued relaxation of regulations that hampered it before the pandemic. Whereas enforcement of compliance with Health Information Portability and Accountability Act will most likely resume, platform operators and providers have had an opportunity to prepare for this. State licensure requirements may also resume; however, the regulations were in the process of becoming more liberal before COVID-19 so that process might continue. There is no reason to anticipate that payment for telemedicine services including check-ins, remote physiologic and therapeutic monitoring, and relaxation of location and service requirements will end. For these reasons, telemedicine therefore is likely to continue as an important part of medical practice.

New technologies are increasingly widespread in biomedicine. Using the consensus definition of new technologies established by the New Technologies Ad-Hoc Committee of the Spanish Society of Neurology (SEN), we evaluated the impact of these technologies on Spanish neurology, based on communications presented at Annual Meetings of the SEN.

We defined the concept of new technology in neurology as a novel technology or novel application of an existing technology, characterised by a certain degree of coherence persisting over time, with the potential to have an impact on the present and/or future of neurology. We conducted a descriptive study of scientific communications presented at the SEN's annual meetings from 2012 to 2018, analysing the type of technology, the field of neurology, and the geographical provenance of the studies.

We identified 299 communications related with new technologies from a total of 8139 (3.7%), including 120 posters and 179 oral communications, ranging from 1.6% of all communicatnications in all neurological subspecialties, with a heterogeneous geographical distribution.

Door-to-needle time (DNT) has been established as the main indicator in code stroke protocols. According to the 2018 guidelines of the American Heart Association/American Stroke Association, DNT should be less than 45minuts; therefore, effective and revised pre-admission and in-hospital protocols are required.

We analysed organisational changes made between 2011 and 2019 and their influence on DNT and the clinical progression of patients treated with fibrinolysis. We collected data from our centre, stored and monitored under the Master Plan for Cerebrovascular Disease of the regional government of Catalonia. Among other measures, we analysed the differences between years and differences derived from the implementation of the Helsinki model.

The study included 447 patients, and we observed significant differences in DNT between different years. Pre-hospital code stroke activation, recorded in 315 cases (70.5%), reduced DNT by a median of 14minutes. However, the linear regression model only showed an inversely proportional relationship between the adoption of the Helsinki code stroke model and DNT (beta coefficient, -0.42; P<.001). The removal of vascular neurologists after the adoption of the Helsinki model increased DNT and the 90-day mortality rate.

DNT is influenced by the organisational model. In our sample, the application of the Helsinki model, the role of the lead vascular neurologist, and notification of code stroke by pre-hospital emergency services are key factors for the reduction of DNT and the clinical improvement of the patient.

Photophobia is a symptom of abnormal light intolerance without pain sensation that requires an anamnesis and an examination to diagnose an underlying etiology.

This article focuses on 30 clinical cases with isolated intense photophobia and on the review of the literature.

The purpose of this article is to establish diagnostic criteria for photophobia.

The etiology of photophobia appears to be at the level of the intrinsically photosensitive retinal ganglion cells known as melanopsin cells and at a neurochemical level mediated by calcitonin-related peptide and the pituitary activating peptide cyclase.

The treatment of photophobia could consist of monoclonal antibodies against calcitonin-related peptide and/or pituitary activating peptide cyclase.

Ischaemic stroke (IS) due to cervical and cerebral artery dissection (CAD) is a rare entity, and few data are available on the use of such reperfusion therapies as intravenous fibrinolysis and mechanical thrombectomy in these patients. We analysed the use of these treatments in patients with IS due to CAD and compared them against patients receiving reperfusion treatment for IS of other aetiologies.

We conducted an observational, retrospective, multicentre study of patients with IS due to CAD recorded in the National Stroke Registry of the Spanish Society of Neurology during the period 2011-2019. Comparative analyses were performed between a) patients with CAD treated and not treated with reperfusion therapies and b) patients treated with reperfusion for IS due to CAD and patients treated with reperfusion for IS due to other causes. Epidemiological data, stroke variables, and outcomes at discharge and at 3 months were included in the analysis.

The study included 21,037 patients with IS 223 (1%) had IS due to CAD, of whom 68 (30%) received reperfusion treatment.
