Aim To determine whether cardiac magnetic resonance imaging (cMRI) is more sensitive than electrocardiogram (ECG) and echocardiogram (ECHO) for detecting myocardial involvement in a Latin American ...migrant population with untreated Chagas disease (CD) in the United States. Materials and methods All untreated CD patients with ECG and ECHO examinations who underwent cMRI at Olive View-UCLA Medical Center from September 2010 to December 2013 ( n =81) were analysed in three groups: Group 1, normal ECG and ECHO examinations ( n =50); Group 2, abnormal ECG and normal ECHO examinations ( n =10); and Group 3, abnormal ECHO examination ( n =21). Frequencies of ECG, ECHO, and cMRI findings were compared across groups. Results Seventy percent (57/81) of the study population was female, with a mean age of 47 years (range, 17–77 years). Twenty-six percent (21/81) had delayed myocardial enhancement (DME), which was most commonly inferolateral in location (27%, 32/117 segments) and transmural in pattern (56%, 65/117 segments). Eight percent (4/50), 30% (3/10), and 67% (14/21) of Groups 1–3, respectively, had DME. Of these individuals with DME, 50% (2/4), 67% (2/3), and 100% (14/14) of Groups 1–3, respectively, also had wall motion abnormality (WMA) on cMRI. In addition to the highest percentages of DME and WMA, Group 3 also had significantly higher mean myocardial mass ( p< 0.01), mean left ventricular end-diastolic ( p< 0.01) and end-systolic volumes ( p< 0.0005), and significantly lower mean left ventricular ejection fraction ( p< 0.001). Conclusion cMRI may detect myocardial involvement in untreated CD that is otherwise unrecognised on ECG and ECHO.
Two new species of Kennedyidae:
Kennedya madygensis
sp. nov and
K. ferganensis
sp. nov. are described from the Middle-Upper Triassic deposits of the Dzhayloucho (Madygen) locality in Kyrgyzstan based ...on new material collected in 2007 and 2009.
K. carpenteri
Pritykina, 1981 is redescribed and variation in its discoidal area and other vein structures is demonstrated. The structure and transformation of the nodus in Kennedyidae are discussed.
A new classification system for Protozygoptera is proposed. It is based on mass material from the Isady, Chekarda and Soyana localities. The new system is based on a set of wing venation characters. ...The hypothesis on the division of Protozygoptera based on their body structures is supplemented and confirmed (Nel et al., 2012). A three-segmented tarsal structure has been established for the archizygopteran family Kennedyidae. The infraorder Permagrionomorpha infraordo nov. is established. An additional character has been proposed to separate archizygopterans and permagrionomorphs based on the structure and morphology of the thorax. Lodeviidae is synonymized with Permagrionidae (junior synonym). Two new families, four new genera and 14 new species are described. A new family Progoneuridae fam. nov. is described based on a significant reduction in the wing longitudinal and transverse venation. It includes the genera
Progoneura
Carpenter, 1931;
Azaroneura
Nel et al., 2012;
Progophlebia
Felker, 2021, and
Issadoneura
gen. nov. (with a new species
Issadoneura marilevorum
gen. et sp. nov.). Based on re-examination of the type material from Chekarda, the genus
Engellestes
Nel et al., 2012 is assigned to a new family Engellestidae fam. nov. The following voltzialestids are described from the Upper Permian of the Vologda Region:
Prototerskeja dubia
gen. et sp. nov.,
Permosticta
elegans
gen. et. sp. nov., and
Permosticta
parva
gen. et sp. nov. The diagnosis of the family Voltzialestidae is changed because of the inclusion of new genera. The genus
Sushkinia
Martynov, 1930 is transferred to Permagrionidae. The following permagrionids are described:
Permagrion sharovi
sp. nov,
Permolestes obscurus
sp. nov.
, P. vjatkensis
sp. nov.,
Salagoulestes
martynovi
sp. nov.,
Solikamptilon aequus
sp. nov.,
Sushkinia angulata
sp. nov.,
Triadolestes sakmarensis
gen. et sp. nov., and
T. mutovkensis
gen. et sp. nov. The new material from Isady and Kargala suggests closer relationships of the Permian Permagrionomorpha and Triassic Triadophlebiomorpha. In the family Kennedyidae,
Kennedya sylvensis
sp. nov. and
K. volatica
sp. nov. are described from Chekarda, and
K. ivensis
Nel et al., 2012 is redescribed from Soyana.
A new species of damselfly of the family Kennedyidae:
Kennedya suchonensis
sp. nov. is described from the Upper Permian (Severodvinian) deposits of the Isady locality (Vologda Region, Velikoustyugsky ...District). Despite the continuity of the main features of wing venation, new species has an unusual structure of the stem’s discoidal area. This structure is not typical of known Paleozoic damselflies, which allows us to re-consider the morphogenesis of this structure. The evolutionary relationships between damselflies of Isady and other kennedyids are discussed.
Two new fossil damselfly species of the family Kennedyidae:
Kennedya kedrovkensis
sp. nov. and
Progoneura kemerovensis
sp. nov. are described from the presumed Lower Triassic beds of the ...Permian-Triassic locality Babiy Kamen’. The new species clearly differ from previously known species of
Kennedya
and
Progoneura
based on the main characters of the wing venation.

Together, SARS-CoV-2 and M. tuberculosis have killed approximately 5.7 million people worldwide over the past 2 years. The COVID-19 pandemic, and the non-pharmaceutical interventions to mitigate ...COVID-19 transmission (including social distancing regulations, partial lockdowns
and quarantines), have disrupted healthcare services and led to a reallocation of resources to COVID-19 care. There has also been a tragic loss of healthcare workers who succumbed to the disease. This has had consequences for TB services, and the fear of contracting COVID-19 may also have
contributed to reduced access to TB services. Altogether, this is projected to have resulted in a 5-year setback in terms of mortality from TB and a 9-year setback in terms of TB detection. In addition, past and present TB disease has been reported to increase both COVID-19 fatality and incidence.
Similarly, COVID-19 may adversely affect TB outcomes. From a more positive perspective, the pandemic has also created opportunities to improve TB care. In this review, we highlight similarities and differences between these two infectious diseases, describe gaps in our knowledge and discuss
solutions and priorities for future research.
One new damselfly genus and species,
Progophlebia tarasenkovae
gen. et sp. nov., and two new species from known genera:
Progoneura kityakensis
sp. nov. and
Kennedya tyulkinensis
sp. nov. of the ...family Kennedyidae (Odonata: Protozygoptera) from several Permian localities (Vyazovka, Kityak, and Tyulkino) of European Russia are described. All known representatives of the family are briefly reviewed. The distinctive features of the localities are characterized.
