Classical swine fever virus (CSFV) is an ancient and economically important flavivirus that utilizes a Rab5-dependent endocytic pathway to enter host cells. Rab22a is a small GTPase that cooperates with Rab5 in the regulation of early endosome dynamics. Until now, the role of Rab22a in the flavivirus life cycle has been poorly defined. In this study, we systematically analyzed the role of Rab22a in CSFV proliferation and internalization using multiple viral replication analyses in combination with the overexpression, knockdown, and mutation of Rab22a, and found that Rab22a is involved in the entry process of CSFV. Confocal microscopy results showed that Rab22a colocalized with virus particles during the early phase of infection. Furthermore, by using glutathione S-transferase pull-down and co-immunoprecipitation assays, we verified the interaction between Rab22a and CSFV non-structural protein NS4B, and determined that NS4B can only bind to wild-type Rab22a, but not to the mutants Q64L and S19N. In addition, we explored the relationship between Rab22a, Rab5 and NS4B in CSFV internalization, and found out that these three proteins bind in early endosomes, and then through a Rab22a-Rab5-NS4B cascade allows the entry of CSFV. Taken together, our findings highlight the role of Rab proteins in CSFV internalization, and extend the understanding of the life cycle of flaviviruses.<br /><br /> Parent engagement in therapeutic services for children with disabilities could optimize service delivery while addressing service disparities. However, service providers must first understand parents' needs to effectively involve parents.<br /><br /> This study examines what needs parents identify as important when engaging with school-based therapies and how well these needs are being met.<br /><br /> Parents of children with Individualized Education Plans rated statements related to their needs for trust, information, support and guidance, and personal needs when engaging with their child's therapies. Parents also provided demographic information on them and their child[ren] with a disability.<br /><br /> Parents endorsed an average of 83 % of needs as important but 51 % of needs as unmet. On average, 65 % of needs related to feeling trusted by service providers were met. In contrast, needs related to receivings upport and guidance (M = 58 %), information (M = 55 %), and addressing parent's own needs (M = 53 %) were frequently unmet. a list of tangible needs school-based providers can use to improve parent engagement with school-based therapies. School-based providers and administrators can use the needs identified as important and unmet in this study to create actionable steps that aim to improve parent engagement in school-based services.This study was a baseline with quantitative data of marine litter along the Gulf of Nicoya, Costa Rica. The objective of the study was to quantify marine litter and its association with human activities in this estuarine gulf. A total of fourteen sandy beaches were cataloged by the degree of urbanization, tourism intensity, beach cleaning programs, and tributary rivers as possible drivers of marine litter presence. The items of the marine litter were separated and weighted by type. Analysis by the clean coastal index (CCI) and multivariate statistics were applied to find spatial patterns in marine litter in the gulf. On beaches with the highest touristic activity, cigarette butts and straws were the main components. Locations with river plume influence, less frequent cleanup, or waste cans showed more bottles, plastic parts, and sanitary waste than beaches in other conditions. A beach in a fisherman town had recently utilized plastic bags, household goods, and boat parts in the marine litter. A wildlife refuge beach showed only small plastic and coffee foam cup fragments that came with currents from other points in the estuary.

We quantified fecal indicator bacteria (FIB) abundances (Escherichia coli and enterococci) from water and sediment samples over one-year survey. Then we measured biological (bacterial abundance, chlorophyll-a), physico-chemical (dissolved nutrients and oxygen, salinity, pH …) and climatic (temperatures, rainfall and tidal coefficient) parameters. Results showed that FIB abundances were occasionally higher than the European regulatory threshold during winter, summer and fall. The "poor quality" of the bathing water was due to high enterococci abundance. We found negative significant correlations between FIB and water temperature and salinity, and positive significant correlations between FIB and rainfall, PO4, NO3, NO2, and SiO2 mainly in water. Relationships between parameters showed that during summer and spring the main environmental drivers were temperature and salinity, while in fall and winter they were rainfall and dissolved nutrients.<br /><br /> Published studies on coronavirus disease 19 (COVID-19) associated rhino-orbito-cerebral mucormycosis (CAROCM) were primarily descriptive. Therefore, we aimed to identify features of COVID-19 that could predispose to CAROCM and explore the pathogenic pathways.<br /><br /> This retrospective hospital-based study was done during the first (March 2020 - January 2021) and the second (February 2021 - June 2021) waves of the COVID-19 pandemic. Subjects were grouped into four categories first-wave CAROCM (n-4); second-wave CAROCM (n-27); first-wave non-mucor COVID (n-75), and second-wave non-mucor COVID (n-50). Data elements included age, gender, comorbidities, COVID-19 severity, steroid therapy, peak values of interleukin-6 (IL-6), serum ferritin and D-dimer, nadir values of absolute lymphocyte count (ALC), absolute neutrophil count (ANC) and platelet count (Pl. C).<br /><br /> Thirty-one patients of CAROCM were included. The mean (SD) age was 51.26 (11.48) years. 27 (87.1%) were aged ≥ 40 years and males. Severe COVID-19 was seen more often in the second wave than the first wave (P-0.001). CAROCM group was significantly younger (P-0.008) and showed a higher incidence of uncontrolled diabetes (P-0.001) and renal dysfunction (P-0.004) than non-mucor COVID. While IL-6, ferritin and D-dimer were significantly elevated in CAROCM than non-mucor COVID, clinical severity, ANC, ALC and Pl. link2 C showed no significant difference.<br /><br /> CAROCM is seen often in middle-aged diabetic males with uncontrolled hyperglycaemia, diabetic ketoacidosis, renal dysfunction and those infected by more transmissible delta variants and treated with steroids. IL-6, D-dimer, serum ferritin are more often elevated in CAROCM and might play a pathogenic role.<br /><br />CAROCM is seen often in middle-aged diabetic males with uncontrolled hyperglycaemia, diabetic ketoacidosis, renal dysfunction and those infected by more transmissible delta variants and treated with steroids.

While vaccine-proximate status epilepticus (VP-SE) has rarely been associated with cases of Dravet syndrome, it is not known whether VP-SE differs clinically from non-vaccine proximate status epilepticus (NVP-SE).<br /><br /> Medical records of children aged ≤24 months, presenting to one of five Australian tertiary pediatric hospitals with their first episode of status epilepticus from 2013 to 2017 were identified using ICD-coded discharge diagnoses. Vaccination history was obtained from the Australian Immunisation Register. Hospitalization details, subsequent epilepsy diagnosis, and vaccination uptake were compared between VP-SE and NVP-SE cases.<br /><br /> Of 245 first status epilepticus hospitalization with immunization records, 35 (14%) were VP-SE and 21 (60%) followed measles-containing vaccines. Vaccine-proximate status epilepticus cases had a median age of 12.5 months [IQR 7.1-14.73], 23 (66%) were in males, 15 (43%) were febrile status epileptins and epilepsy diagnosis were associated with having seizure prior to their first SE.<br /><br /> Little is known about the use of novel heated tobacco products (HTPs) in low- and middle-income countries. We examined among smokers in Mexico the prevalence and correlates of HTP use, as well as reasons for using HTPs.<br /><br /> We analyzed data from five surveys (November 2019-March 2021) of an open cohort of adult smokers (n=6500), including an oversample of those who also use e-cigarettes. link3 Mixed-effects multinomial logistic models were used to estimate associations between study variables and current HTP use or prior HTP trial relative to never trying HTPs.<br /><br /> The weighted prevalence of current HTP use was 1.1%. Independent correlates of current HTP use included smoking frequency, intention to quit, e-cigarette use, having partners/family-members who use e-cigarettes, friends who use HTPs, and exposure to HTP information inside/outside tobacco shops. Having partners/family members who smoke and not knowing about the harm of HTPs relative to cigarettes were associated with lower likelihood of current HTP use. Having tried HTPs was more likely among light daily smokers, those with family who use HTPs and exposure to HTP information outside shops and on newspapers/magazines. Among current users, the top reasons for using HTPs were greater social acceptability (50.6%) and lower perceived harm (34.9%) relative to cigarettes.<br /><br /> Uptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use. Further research is needed to determine if HTPs use promotes or impedes smoking cessation, given current HTP users are also likely to use various nicotine products.<br /><br />Uptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use.

Law enforcement drug seizure data present a unique opportunity to examine the association between illicit-stimulant-involved overdose deaths (ISODs) and the illicit drug supply. Our objective is to better understand correlations between illicit drug market trends and increases in ISODs in Ohio in 2014-2019.<br /><br /> This observational study analyzes the universe of ISODs and drug seizures in Ohio from 2014 to 2019. We use graphs and descriptive statistics to characterize trends over time and estimate a time series model of their association. ISODs were summed to yield monthly statewide counts of seizures containing methamphetamine, cocaine, illicitly manufactured fentanyl (IMF), and other non-IMF opioids (e.g., heroin). All rates were calculated per 100,000 persons.<br /><br /> Roughly 80% of ISODs in Ohio from 2014 to 2019 involved an opioid, with IMF co-occurring in 90% of ISODs by 2019.
