Published: June 2022

A revision of microscope slides deposited between 2014 and 2017 in the collection of Rocha and Doma (National University of La Pampa, Argentina) revealed three new species of the genus Milnesium Doyère, 1840: M. pelufforum sp. nov., M. irenae sp. nov. and M. quiranae sp. nov. Milnesium pelufforum sp. nov. is mostly characterized by ten transverse bands of sculptured cuticle and pseudoplates (the first band, until now, never detected in the genus), six peribuccal lamellae and claw configuration [2-2]-[2-2] in young or [2-3]-[3-2] in senior specimens. Milnesium irenae sp. nov. is mostly characterized by complex cuticular ornamentation including a fine reticulation different from the typical one in the genus; it also has pseudoplates, six peribuccal lamellae, medioventral peribuccal papilla reduced, stylets, their furcae and supports very developed, and claw configuration [2-3]-[2-2]. Milnesium quiranae sp. nov. is mostly characterized by smooth cuticle, six peribuccal lamellae, and claw configuration [3-3]-[3-3]; with growing, the medioventral peribuccal papilla reduces and the buccal tube becomes wider. With the present contribution the genus Milnesium now has 48 valid species, and the number of described limno-terrestrial tardigrade species from South America has risen to 11, including 8 from Argentina with 5 from Salta and La Pampa province.

Published: June 2022

Context.—
COVID-19 has been associated with liver injury, and a small subset of patients recovering from severe disease have shown persistent markedly elevated liver biochemistries for months after infection.

Objective.—
To characterize persistent biliary injury after COVID-19.

Design.—
A search of the pathology archives identified 7 post–COVID-19 patients with persistent biliary injury, and the clinical, radiologic, and pathologic features were assessed.

Results.—
All patients in this cohort presented with respiratory symptoms and had a complicated clinical course with acute elevation of liver biochemistries. Alkaline phosphatase (ALP) was markedly and persistently elevated after discharge (median peak ALP, 1498 IU/L, at a median of 84 days from diagnosis). Magnetic resonance cholangiopancreatography showed 3 patients with irregularity, stricturing, and dilatation of intrahepatic ducts; no radiographic abnormalities were identified in the remaining 4 patients. Liver biopsies showed mild portal changes with features of cholestatic injury in 4 patients (bile duct injury and canalicular cholestasis) and marked biliary obstruction in 2 patients (profound cholestasis, ductular reaction, and bile infarcts), but no SARS-CoV-2 RNA was identified on in situ hybridization. On follow-up, most patients had minimal intervention and showed marked improvement of liver biochemistries but with mild persistent elevation of ALP.

Conclusions.—
A subset of critically ill COVID-19 patients demonstrates marked and persistent cholestatic injury, with radiographic and histologic evidence of secondary sclerosing cholangitis, suggesting that cholestatic liver disease and secondary sclerosing cholangitis may be long-term sequelae of COVID-19 acute illness as a longstanding manifestation of critical illness.
‘I love you’: the first phrase detected from dreams
Authors: Raduga Michael 
Published: June 2022

Objective Many people have dreams nightly and some maintain consciousness during dreams. Such dreams are referred to as lucid dreams (LD). During dreams, our speech correlates with facial muscle activity, which is hard to decode, but LD could solve this problem. The primary hypothesis of this study was that the facial muscles electric activity during LD corresponds to specific sounds. Understanding this connection could help decode dream speech in the future.
Material and Methods Under laboratory conditions, four LD practitioners were asked to say “I love you”, a phrase with a distinctive electromyographic (EMG) signature. They did this before falling asleep and then again after becoming conscious during a dream. Their facial and neck EMG was recorded in four areas.
Results All four volunteers accomplished the goal at least once. The patterns associated with the “I love you” phrase were observed in most cases, both during wakefulness and LD. Specifically, the “I” triggered distinctive phasic activity in the submentalis area most of the time, while “you” did the same in the orbicularis oris.
Discussion This study highlights the possibility of detecting only specific and highly EMG distinctive phrases from dreams because vocalization also involves a tong and vocal apparatus. The most interesting consequence of the present results is that they indicate the possibility of creating an artificial EMG language that could be instantly decoded in reality and used during LD.

Published: June 2022

Objectives To identify the factors associated with the occurrence of sleepiness among nursing professionals.
Material and Methods A case-control study nested in a cross-sectional one, conducted with 364 controls and 121 cases. Data on demographic and occupational characteristics were collected, as well as about lifestyle, physical and psychosocial work environment and somnolence. A multiple logistic regression analysis was performed.
Results The independent factors associated with the presence of sleepiness were as follows: imbalance between efforts and rewards (ORa=3.81; p<0.001), high overcommitment (ORa=3.20; p<0.001), workload equal to or greater than 45 hours a week (ORa=2.30; p=0.001), situations that can generate pain/injury with moderate or high exposure (ORa=1.85; p=0.037), and night work (ORa=1.71; p=0.038). The model was adjusted by gender and age group.
Conclusion Individual and historical-occupational characteristics and, mainly, those related to the physical and psychosocial work environment, were associated with the occurrence of sleepiness. Public and institutional preventive policies must include improvements in the conditions of the physical and psychosocial work environment, as well as strengthening of the individual resources.

Introduction The experience of living with chronic pain allows for the appearance of changes in sleep patterns, mood, and stress levels.
Objective To describe the phases of stress and the quality of sleep in patients with chronic pain.
Material and Methods Cross-sectional study carried out at the pain clinic of the HUPES Complex, Salvador-Bahia. Data collection between March 2016 and November 2017. Instruments: Sociodemographic questionnaire, Numerical Pain Scale (EVN), Mini-Sleep Questionnaire (MSQ), and Stress Symptoms Inventory for LIPP adults (ISSL). Categorical variables were expressed by absolute and relative frequency and quantitative variables by means and standard deviation (SD). The comparison of categorical variables was performed using the chi-square test. Values of p<0.05 were considered statistically significant.
Results Mean age (standard deviation) of 50.0 (10) years, 89.6% of whom were female. Predominance of people with a partner, with religion, high school, and unemployed or removed by the INSS. They have severe sleep disorders, severe pain, and the presence of stress in the resistance phase. Most subjects reveal that they have improved with the treatment and have moderate self-esteem and personal satisfaction, despite the presence of anxious and depressive symptoms.
Conclusion Chronic pain has a very significant impact on life, increasing the level of stress, compromising and limiting daily activities, and showing more presence of anxious and depressive symptoms in people who suffer from chronic pain.

Authors: Carvalho Bruno Miguel Santos , Chaves João , Silva António Martins da 
Published: June 2022

Objectives Physiological and restorative sleep is fundamental for physical and mental well-being. Polysomnography parameters are objective methods to access sleep structure. Antiepileptic drugs (AEDs) are a group of drugs whose interference in the sleep structure is still not well known, especially in what concern the new ones. We did a systematic review of the literature to compare the effect of classic and newer AEDs on sleep architecture.
Material and Methods A search was performed in PubMed and Scopus, using keywords “sleep” and “antiepileptics”, and each AED combined with “sleep”. Only studies concerning objective measures were selected.
Results 63 articles were included, only 21 were randomized, controlled and double-blinded. Studies not only in epilepsy, but also in restless leg syndrome, bruxism, insomnia, fibromyalgia and obstructive sleep apnea were found. Among classic AEDs, carbamazepine has a negative effect on sleep while phenobarbitone has a slightly dose-dependent interference and is also the only one to reduce N3 stage. Valproic acid has little to no effect while clobazam and clonazepam have a positive effect. No conclusion can be drawn about phenytoin. All of them reduce REM stage. In the newer AEDs group gabapentine, lamotrigine, perampanel, pregabaline and tiagabine increase N3 sleep in best evidence. Lacosamide and zonisamide appear to be innocent while levetiracetam reduces REM sleep.
Conclusion Studies found used different methodologies not always addressing the analysis on the same parameters. In spite of these, newer AEDs have less effects on sleep structure when compared with classic AEDs but furthermore robust evidence is needed.

Multi-constraints based deep learning model for automated segmentation and diagnosis of coronary artery disease in X-ray angiographic images
Authors: Algarni Mona , Al-Rezqi Abdulkader , Saeed Faisal , Alsaeedi Abdullah , Ghabban Fahad 
Published: June 2022

Background
The detection of coronary artery disease (CAD) from the X-ray coronary angiography is a crucial process which is hindered by various issues such as presence of noise, insufficient contrast of the input images along with the uncertainties caused by the motion due to respiration and variation of angles of vessels.

Methods
In this article, an Automated Segmentation and Diagnosis of Coronary Artery Disease (ASCARIS) model is proposed in order to overcome the prevailing challenges in detection of CAD from the X-ray images. Initially, the preprocessing of the input images was carried out by using the modified wiener filter for the removal of both internal and external noise pixels from the images. Then, the enhancement of contrast was carried out by utilizing the optimized maximum principal curvature to preserve the edge information thereby contributing to increasing the segmentation accuracy. Further, the binarization of enhanced images was executed by the means of OTSU thresholding. The segmentation of coronary arteries was performed by implementing the Attention-based Nested U-Net, in which the attention estimator was incorporated to overcome the difficulties caused by intersections and overlapped arteries. The increased segmentation accuracy was achieved by performing angle estimation. Finally, the VGG-16 based architecture was implemented to extract threefold features from the segmented image to perform classification of X-ray images into normal and abnormal classes.

Results
The experimentation of the proposed ASCARIS model was carried out in the MATLAB R2020a simulation tool and the evaluation of the proposed model was compared with several existing approaches in terms of accuracy, sensitivity, specificity, revised contrast to noise ratio, mean square error, dice coefficient, Jaccard similarity, Hausdorff distance, Peak signal-to-noise ratio (PSNR), segmentation accuracy and ROC curve.

Discussion
The results obtained conclude that the proposed model outperforms the existing approaches in all the evaluation metrics thereby achieving optimized classification of CAD. The proposed method removes the large number of background artifacts and obtains a better vascular structure.
The Effects of Methanolic Plant Extract on the Haematological Indices of Induced Preeclamptic Wistar Rats
Authors: Atoe Kenneth , Idu Macdonald 
Published: June 2022

Aims: Preeclampsia can have a deleterious impact on hematological parameters of pregnant women. Management of this medical condition is critical for improving mother and fetal outcomes. Alternative phytomedicinal intervention is becoming more popular in prenatal care. The current study looked into the effects of methanolic extracts of Jatropha curcas, Alchonnea cordifolia, and Secamone afzelii on haematological markers in preeclamptic Wistar rats.
Study Design: The study was a trial using an animal model.
Place and Duration of Study: The study was conducted in the University of Benin, Nigeria in July 2019.
Methodology: Age-matched (3 days) female Wistar rats weighing 220 to 256 g were used in the study (mean, 237 g). The Adriamycin Model was utilized in Wistar rats to induce preeclampsia. Methanolic extracts of Jatropha curcas, Alchonnea cordifolia, and Secamone afzelii were given to the rats in doses of 50, 100, and 200 mg/kg. The animals were anaesthetized with chloroform and humanely slaughtered (use ‘sacrificed’ instead) twenty-four (24) hours after the last dosage of the standard medicine and various treatment extracts were administered to the relevant groups. Blood samples were drawn from the aorta and transferred to tubes containing the anticoagulant EDTA before being evaluated for the various parameters on an Auto Haematology Analyzer Model XrHA640.
Results: White cell count was 6.77x103 in the control group, but when preeclampsia was developed, WBC plummeted to 5.8x103. However, when preeclamptic rats were given 100mg/kg of Secamone afzeli extracts, their WBC increased to 9.75x103. A similar increase in hematological differentials was observed in lymphocytes when preeclampsia dramatically reduced lymphocyte volume to 1.1% against 1.17 % in the control. The mean corpuscular volume in the control group was 71.6fL, but when preeclampsia was induced, it dropped to 67.0fL. This improved to 78.6fL when the normal medication was supplied, and 81.6fL when 50mg of Alchonnea cordifolia extracts were administered.
Conclusion: According to the findings, extracts of several plants (be specific and mention the plants used in the study) generated increases in PCV to varying degrees, and hence might be utilized to treat anemia. Their ability to improve platelet counts at various levels showed that they could be used in the treatment of thrombocytopenia. The extracts can help improve immune responses by increasing white cell numbers.

AbstractThe key to breaking through the capacity limitation imposed by intercalation chemistry lies in the ability to harness more active sites that can reversibly accommodate more ions (e.g., Li+) and electrons within a finite space. However, excessive Li‐ion insertion into the Li layer of layered cathodes results in fast performance decay due to the huge lattice change and irreversible phase transformation. In this study, an ultrahigh reversible capacity is demonstrated by a layered oxide cathode purely based on manganese. Through a wealth of characterizations, it is clarified that the presence of low‐content Li2MnO3 domains not only reduces the amount of irreversible O loss; but also regulates Mn migration in LiMnO2 domains, enabling elastic lattice with high reversibility for tetrahedral sites Li‐ion storage in Li layers. This work utilizes bulk cation disorder to create stable Li‐ion‐storage tetrahedral sites and an elastic lattice for layered materials, with a reversible capacity of 600 mA h g−1, demonstrated in th range 0.6–4.9 V versus Li/Li+ at 10 mA g−1. Admittedly, discharging to 0.6 V might be too low for practical use, but this exploration is still of great importance as it conceptually demonstrates the limit of Li‐ions insertion into layered oxide materials.
