Background and Purpose:
We investigated whether the signal change on fluid-attenuated inversion recovery (FLAIR) can serve as a tissue clock that predicts the clinical outcome after endovascular thrombectomy (EVT), independently of the onset-to-admission time.

Methods:
Consecutive patients with acute stroke treated with EVT between September 2014 and December 2018 were enrolled. Based on the parenchymal signal change on FLAIR, patients were classified into FLAIR-negative and FLAIR-positive groups. The clinical characteristics, imaging findings, EVT parameters, and the intracranial hemorrhage defined as Heidelberg Bleeding Classification ≥1c hemorrhage (parenchymal hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, and/or subdural hemorrhage) were compared between the 2 groups. A modified Rankin Scale score 0 to 1 at 3 months was considered to represent a good outcome.

Results:

Of the 227 patients with EVT during the study period, 140 patients (62%) were classified into the FLAIR-negative group and 87 (38%) were classified into the FLAIR-positive group. In the FLAIR-negative group, the patients were older (
P
=0.011), the onset-to-image time was shorter (
P
<0.001), the frequency of cardioembolic stroke was higher (
P
=0.006), and the rate of intravenous thrombolysis was higher (
P
<0.001) in comparison to the FLAIR-positive group. Although the rate of complete recanalization after EVT did not differ between the 2 groups (
P
=0.173), the frequency of both any-intracranial hemorrhage and Heidelberg Bleeding Classification ≥1c hemorrhage were higher in the FLAIR-positive group (
P
=0.004 and 0.011). At 3 months, the percentage of patients with a good outcome (FLAIR-negative, 41%; FLAIR-positive, 27%) was significantly related to the FLAIR signal change (
P
=0.047), while the onset-to-image time was not significant (
P
=0.271). A multivariate regression analysis showed that a FLAIR-negative status was independently associated with a good outcome (odds ratio, 2.10 [95% CI, 1.02–4.31],
P
=0.044).

Conclusions:
A FLAIR-negative status may predict the clinical outcome more accurately than the onset-to-admission time, which may support the role of FLAIR as a tissue clock.
Annotated world checklist of the Trombiculidae and Leeuwenhoekiidae (1758–2021) (Acari: Trombiculoidea), with notes on nomenclature, taxonomy, and distribution
Authors: NIELSEN DAVID H. , ROBBINS RICHARD G. , RUEDA LEOPOLDO M. 
Published: May 2021

The superfamily Trombiculoidea is a large and diverse group of acarines that comprises six families; of these, the families Trombiculidae and Leeuwenhoekiidae are characterized by larvae commonly known as chiggers that are parasites of terrestrial vertebrates, including humans, and some species are of medical importance as vectors of chigger-borne rickettsiosis (scrub typhus), caused by the rickettsia Orientia tsutsugamushi. This paper presents an annotated checklist of 3,013 generally accepted chigger species, together with their distribution by zoogeographic region, and a non-comprehensive list of synonyms. A total of 58 new combinations are proposed by transferring species to different genera, treating some subgenera as genera, or updating current generic names. The checklist updates earlier catalogs of the world chigger fauna, but because the literature on chigger taxonomy is voluminous and scattered, similar, regional monographs were utilized in constructing the classificatory foundation. This list may not contain every species, synonym or taxonomic rearrangement that has been published, but it reflects the most recent arrangement of chigger taxa. Distribution records are primarily drawn from collection sites listed in the original species descriptions, together with subsequently published geographical records.

Authors: SINCLAIR BRADLEY J. , SHAMSHEV IGOR V. 
Published: May 2021

Iteaphila Zetterstedt is redefined to include species with both branched and unbranched radial vein (R4+5) on the basis of a morphological cladistic analysis and parsimony analysis of COI mitochondrial DNA barcode sequences. As a result, Anthepiscopus Becker is hypothesized as a junior synonym of Iteaphila and species of the Iteaphila setosa group are transferred to the new genus, Paraiteaphila gen. nov. The following new combinations are proposed: P. arundela (Shamshev & Sinclair, 2009) comb. nov., P. caucasica (Shamshev & Sinclair, 2009) comb. nov., P. italica (Loew, 1873) comb. nov., P. kubaniensis (Shamshev & Sinclair, 2009) comb. nov., P. merzi (Shamshev & Sinclair, 2009) comb. nov. and P. setosa (Bezzi, 1924) comb. nov. These two genera are assigned to the family Iteaphilidae stat. rev. Thirty-five species of Iteaphila with unbranched radial vein are revised, including 26 new species: bulbosa species group (I. beringiensis sp. nov., I. bifida sp. nov., I. recta sp. nov., I. tribulosa sp. nov.), macquarti species group (I. bartaki sp. nov., I. falki sp. nov., I. kyrgyzstanensis sp. nov., I. ribesii (Becker, 1891) comb. nov.), nitidula species group (I. longiphallus sp. nov.), nupta species group (I. arnaudi sp. nov., I. bayarea sp. nov., I. brooksi sp. nov., I. dichoptica sp. nov., I. flavipilosa (Coquillett, 1900) comb. nov., I. glabricula sp. nov., I. gracilis sp. nov., I. grandis sp. nov., I. lolo sp. nov., I. longipalpis (Melander, 1928) comb. nov., I. luteitibia sp. nov., I. nupta (Melander, 1928) comb. nov., I. sierrensis sp. nov., I. spinosa sp. nov., I. subnupta sp. nov.), oedalina species group (I. aktruensis sp. nov., I. incus sp. nov., I. miranda sp. nov., I. oedalina (Zetterstedt, 1838) comb. nov., I. polygyna (Melander, 1928) comb. nov., I. recurvata sp. nov., I. sakhalinensis sp. nov., I. zontaki (Nowicki, 1871) comb. nov.), stentor species group (I. parastentor sp. nov., I. stentor (Melander, 1902) comb. nov.) and unplaced to species group (I. caelebs (Becker, 1891) comb. nov.). The following new synonyms are proposed: I. flavicoxa (Melander, 1928) is a junior synonym of I. polygyna (Melander, 1928); I. hirsutus (Melander, 1928) is a junior synonym of I. oedalina (Zettersedt, 1838). Lectotypes are designated for the following species: I. flavipilosa, I. fraternella Zetterstedt, I. nigra Zetterstedt, I. nupta, I. oedalina, I. polygyna and I. ribesii. All species of Iteaphila with unbranched R4+5 are described, key to species presented, male terminalia illustrated, distributions plotted and flowers visited by these species are listed. COI mitochondrial DNA barcode sequences were obtained for 18 identified Nearctic species of Iteaphila with both branched and unbranched R4+5.

AbstractThe Atmospheric Carbon and Transport (ACT)-America NASA Earth Venture Suborbital Mission set out to improve regional atmospheric greenhouse gas (GHG) inversions by exploring the intersection of the strong GHG fluxes and vigorous atmospheric transport that occurs within the midlatitudes. Two research aircraft instrumented with remote and in situ sensors to measure GHG mole fractions, associated trace gases, and atmospheric state variables collected 1,140.7 flight hours of research data, distributed across 305 individual aircraft sorties, coordinated within 121 research flight days, and spanning five 6-week seasonal flight campaigns in the central and eastern United States. Flights sampled 31 synoptic sequences, including fair-weather and frontal conditions, at altitudes ranging from the atmospheric boundary layer to the upper free troposphere. The observations were complemented with global and regional GHG flux and transport model ensembles. We found that midlatitude weather systems contain large spatial gradients in GHG mole fractions, in patterns that were consistent as a function of season and altitude. We attribute these patterns to a combination of regional terrestrial fluxes and inflow from the continental boundaries. These observations, when segregated according to altitude and air mass, provide a variety of quantitative insights into the realism of regional CO2 and CH4 fluxes and atmospheric GHG transport realizations. The ACT-America dataset and ensemble modeling methods provide benchmarks for the development of atmospheric inversion systems. As global and regional atmospheric inversions incorporate ACT-America’s findings and methods, we anticipate these systems will produce increasingly accurate and precise subcontinental GHG flux estimates.

Abstract
Background
It has been pointed out that prolonged television (TV) viewing is one of the sedentary behaviors that is harmful to health; however, the association between socioeconomic status (SES) and prolonged TV viewing time has not been sufficiently investigated in Japan.

Methods
The study population are the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2752 adults. SES was classified according to the employment status, educational attainment, living status, and equivalent household expenditure (EHE). Prolonged TV viewing time was defined as more than or equal to 4 h of TV viewing per day. Multivariable logistic regression analyses were conducted to examine the association of SES with prolonged TV viewing time.

Results
The mean TV viewing time was 2.92 h in all participants. Of 2752 participants, 809 (29.4%) prolonged TV viewing, and the mean TV viewing time of them was 5.61 h. The mean TV viewing time in participants without prolonged TV viewing time was 1.81 h. The mean TV viewing time was prolonged as age classes increased and significantly longer in aged ≥60 years. Prolonged TV viewing time was associated with not working for all age classes and sexes. Only among women, education attainment and living status were also associated with prolonged TV viewing time. For education attainment, the lower the received years of education, the higher odds ratios (OR) of prolonged TV viewing time. For living status, in women aged <60 years, living with others had a significantly higher OR compared to living with spouse. On the other hand, in women aged ≥60 years, living alone had a significantly higher OR. EHE did not have any significant associations with prolonged TV viewing time.

Conclusions
In a general Japanese population, it should be noted that the association between SES and prolonged TV viewing time differed by age and sex. Particularly, it must draw attention to the prolonged TV viewing in elderly. The intervention in order to shorten TV viewing time needs to consider these attributes.

Abstract
Background
Cardiac tumors are very uncommon compared to other cardiac diseases. Their clinical symptoms can vary from absent to non-specific. The most common symptoms are arrhythmias, blood flow obstruction due to valvular dysfunction, shortness of breath, systemic embolization, and accumulation of pericardial fluid. Hereby, we describe a very rare case of a diffuse large B cell lymphoma patient who presented with the symptoms and signs of acute coronary syndrome (ACS) but the patient’s complaints were caused by his intramyocardial lymphoma metastasis.

Case presentation
Forty-eight-year-old diffuse large B cell lymphoma patient was admitted to our emergency department with chest pain, effort dyspnea, and fever. The patient had normal blood pressure, blood oxygen saturation, sinus tachycardia, fever, crackles over the left lower lobe, novum incomplete right bundle branch block with Q waves and minor ST alterations, elevated C-reactive protein, high-sensitivity troponin-T, and d-dimer levels. Chest X-ray revealed consolidation on the left side and enlarged heart. Bed side transthoracic echocardiography showed inferior akinesis with pericardial fluid. Coronary angiography showed no occlusion or significant stenosis. Chest computed tomography demonstrated the progression of his lymphoma in the myocardium. He was admitted to the Department of Hematology for immediate chemotherapy and he reached complete metabolic remission, followed by allogeneic hematopoietic stem cell transplantation. Unfortunately, about 9 months later, he developed bone marrow deficiency consequently severe sepsis, septic shock, and multiple organ failure what he did not survive.

Conclusions
Our case demonstrates a very rare manifestation of a heart metastasis. ACS is an unusual symptom of cardiac tumors. But our patient’s intramyocardial lymphoma in the right atrium and ventricle externally compressed the right coronary artery and damaged the heart tissue, causing the patient’s symptoms which imitated ACS. Fortunately, the quick diagnostics and immediate aggressive chemotherapy provided the patient’s remission and suitability to further treatment.

Published: May 2021

AbstractSabah in Malaysian Borneo is among the Malaysian states which reported a high number of detected COVID-19 cases during the current pandemic. Due to geographical challenges and limited resources, clinicians developed novel strategies for managing patients. The use of a dual oxygen concentrator system for mechanical ventilation is one of the innovations developed by retrieval team members from the Emergency Department (ED) of the Sabah Women and Children’s Hospital. Due to conditions requiring isolation of patients suspected of or positive for COVID-19, high-risk patients were treated in an ED extension area that lacked central wall oxygen. Direct access to oxygen tanks became the only viable option, but ensuring a continuous supply was laborious. The novel setup described within this paper has been used on intubated patients in the ED extension area with moderate to high ventilator settings successfully. This simple setup, designed to meet the limited resources within a pandemic environment, needed only a turbine-driven ventilator, two oxygen concentrators, a 3-way connector, and three oxygen tubing. The application of this setup could potentially save more critically ill patients who are being managed in resource-limited conditions such as in smaller district hospitals or out in the field.

AbstractPurposeTo investigate the effect of dexmedetomidine on intraoperative blood glucose hemostasis in elderly patients undergoing non-cardiac major surgery.MethodsThis was secondary analysis of a randomized controlled trial. Patients in dexmedetomidine group received a loading dose dexmedetomidine (0.6 μg/kg in 10 min before anaesthesia induction) followed by a continuous infusion (0.5 μg/kg/hr) till 1 h before the end of surgery. Patients in control group received volume-matched normal saline at the same time interval. Primary outcome was the incidence of intraoperative hyperglycemia (blood glucose higher than 10 mmol/L).Results303 patients in dexmedetomidine group and 306 patients in control group were analysed. The incidence of intraoperative hyperglycemia showed no statistical significance between dexmedetomidine group and control group (27.4% vs. 22.5%, RR = 1.22, 95%CI 0.92–1.60,P = 0.167). Median value of glycemic variation in dexmedetomidine group (2.5, IQR 1.4–3.7, mmol) was slightly lower than that in control group (2.6, IQR 1.5–4.0, mmol),P = 0.034. In multivariable logistic analysis, history of diabetes (OR 3.007, 95%CI 1.826–4.950,P < 0.001), higher baseline blood glucose (OR 1.353, 95%CI 1.174–1.560,P < 0.001) and prolonged surgery time (OR 1.197, 95%CI 1.083–1.324,P < 0.001) were independent risk factors of hyperglycaemia.ConclusionsDexmedetomidine presented no effect on intraoperative hyperglycemia in elderly patients undergoing major non-cardiac surgery.Trial registrationPresent study was registered at Chinese Clinical Trial Registry on December 1, 2015 (www.chictr.org.cn, registration number ChiCTR-IPR-15007654).

Abstract
Background
Low testing rates and delays in reporting hinder the estimation of the mortality burden associated with the COVID-19 pandemic. During a public health emergency, estimating all cause excess deaths above an expected level of death can provide a more reliable picture of the mortality burden. Here, we aim to estimate the absolute and relative mortality impact of COVID-19 pandemic in Mexico.

Methods
We obtained weekly mortality time series due to all causes for Mexico, and by gender, and geographic region from 2015 to 2020. We also compiled surveillance data on COVID-19 cases and deaths to assess the timing and intensity of the pandemic and assembled weekly series of the proportion of tweets about ‘death’ from Mexico to assess the correlation between people’s media interaction about ‘death’ and the rise in pandemic deaths. We estimated all-cause excess mortality rates and mortality rate ratio increase over baseline by fitting Serfling regression models and forecasted the total excess deaths for Mexico for the first 4 weeks of 2021 using the generalized logistic growth model.

Results
We estimated the all-cause excess mortality rate associated with the COVID-19 pandemic in Mexico in 2020 at 26.10 per 10,000 population, which corresponds to 333,538 excess deaths. Males had about 2-fold higher excess mortality rate (33.99) compared to females (18.53). Mexico City reported the highest excess death rate (63.54) and RR (2.09) compared to rest of the country (excess rate = 23.25, RR = 1.62). While COVID-19 deaths accounted for only 38.64% of total excess deaths in Mexico, our forecast estimate that Mexico has accumulated a total of ~ 61,610 [95% PI: 60,003, 63,216] excess deaths in the first 4 weeks of 2021. Proportion of tweets was significantly correlated with the excess mortality (ρ = 0.508 [95% CI: 0.245, 0.701], p-value = 0.0004).

Conclusion
The COVID-19 pandemic has heavily affected Mexico. The lab-confirmed COVID-19 deaths accounted for only 38.64% of total all cause excess deaths (333,538) in Mexico in 2020. This reflects either the effect of low testing rates in Mexico, or the surge in number of deaths due to other causes during the pandemic. A model-based forecast indicates that an average of 61,610 excess deaths have occurred in January 2021.

AbstractBackgroundObesity or overweight in children is an excessive accumulation of adipose tissue that can potentially regress health indicators and increase the likelihood of various diseases.ObjectivesThis model was implemented to improve the nutritional status and lifestyle behavior of children aged 6–12 years with overweight/obesity.MethodsA quasi-experimental design with 90 participants in each control and intervention group with a multistage cluster random sampling method after reviewing the literature, and their screening by experts were adopted.ResultsAfter 6 months there were significant differences in Body Mass Index and weight for age percentile values of children allocated in control and intervention groups after controlling for beginning values (p = 0.024, Partial eta2 = 0.028, 0.044, Partial eta2 = 0.023), respectively. Although there was an increased rate in BMI and weight for age percentile in both groups this increase in the control group after the 6th month significantly was more than that in the intervention group after the 6th months. A considerable difference in BMI of girls after the intervention was observed in the experimental group (p = 0.006, Partial eta2 = 0.092). However, our results showed that there was no significant difference in BMI of boys in the intervention and control groups before and 6 months after the intervention (p = 0.507).ConclusionsWe conclude that though the weight increase rate was lower in the experimental group, the implemented model alone was not enough.Trial registrationIranian Registry of Clinical Trials (IRCT):IRCT20200717048124N1at 05/08/2020, retrospectively registered.
