This study retrieved the transcriptome profiling data of 552 endometrial cancer (EC) patients from the TCGA (The Cancer Genome Atlas) database, and identified 1297 lncRNAs (long noncoding RNAs) related to autophagy genes using Pearson correlation analysis. Univariate Cox regression analysis of the training data set revealed that 14 autophagy-related lncRNAs had significantly prognostic value for endometrial cancer (P less then 0.01). Multivariate Cox regression analysis of these autophagy-related lncRNAs established the following autophagy-related lncRNA prognosis signature for endometrial cancer PI = (0.255 × AC005229.4 expression) + (0.405 × BX322234.1 expression) + (0.169 × FIRRE expression value) + (-0.122 × RAB11B-AS1 expression) + (-0.338 × AC003102.1 expression). This signature was validated in both the testing data set and the entire data set. The areas under the receiver operating characteristics curves for the 1-, 3-, and 5-year overall survival rates in the entire data set were 0.772, 0.733, and 0.714, respectively. In addition, a gene set enrichment analysis confirmed that cancer-related and autophagy-related pathways were significantly up-regulated in the high-risk group. In summary, this study has demonstrated that a signature comprising five autophagy-related lncRNAs has potential as an independent prognostic indicator of endometrial cancer, and also that these lncRNAs may play a key role in the development of endometrial cancer.
Circular RNAs (circRNAs) is one kind of non-coding RNAs (ncRNAs) and exert crucial functions in biological processes and intracellular gene expression modulation. However, the biological roles and expression status of the majority of circRNAs still remain unknown in cervical cancer.

In this study, circEPSTI1 (hsa_circRNA_000479) was significantly upregulated in cervical cancer. We first discovered the impact of circRNA on cell ferroptosis in cervical cancer. Interestingly, circEPSTI1 attenuates the effect of ferritin which is mediated by SLC7A11 based on lipid peroxidation measurements and reduced glutathione and glutathione (GSH/GSSG) assay.

circEPSTI1-miR-375/409-3P/515-5p-SLC7A11 axis affected the proliferation of cervical cancer via the competing endogenous RNAs (ceRNA) mechanism and was relative to ferroptosis. Our findings provided experimental evidences which revealed that circEPSTI1 might act as a new and useful biomarker for monitoring and treatment target for cervical cancer.

The expression of circEPSTI1 was examined in cervical cancer cells. Then, we observed the impact of circEPSTI1 expression on the proliferation of cervical cancer by loss-of-function assays both
and
. RIP and luciferase reporter assay revealed that circEPSTI1 sponges miR-375, miR-409-3p and miR-515-5p to upregulate SLC7A11 expression. We applied mouse xenograft experiments in mice to validate our results.

Mitochondrial impairment is a hallmark of frailty and sarcopenia in the elderly. However, the exact mechanism underlying the development of obesogenic sarcopenia and the involvement of mitochondria remains unclear. This study confirmed that there is a decline in muscle mass and function as well as mitochondrial dysfunction in the quadriceps of ovariectomized (OVX) mice. To investigate the role of microRNA (miRNA) in this process, we performed miRNA and mRNA arrays and found that miR-141-3p directly targets and downregulates FK506 binding protein 5 (Fkbp5) and Fibin. Overexpression of miR-141-3p decreased mitochondrial function and inhibited myogenic differentiation in C2C12 cells. These effects were mediated by Fkbp5 and Fibin inhibition. Conversely, knockdown of miR-141-3p increased mitochondrial respiration and enhanced myogenesis. Treatment with β-estradiol effectively reversed the palmitic acid-induced upregulation of miR-141-3p and subsequent downregulation of Fkbp5 and Fibin. In conclusion, miR-141-3p is upregulated in OVX mice, and this is associated with mitochondrial dysfunction through inhibition of Fkbp5 and Fibin. These findings suggest that inhibiting miR-141-3p could be a therapeutic target for alleviating obesogenic sarcopenia.The Duffy blood group is a critical receptor for Plasmodium vivax (Pv) invasion of red blood cells, and consequently, Pv infections were considered rare in sub-Saharan Africa where the prevalence of Duffy-negativity is high. However, recently, Pv infections have been found in Duffy-negative Africans throughout the malaria transmission area of sub-Saharan Africa, raising important questions concerning the molecular composition of these Pv clones and the red blood cell receptors that facilitate their invasion. Here, we describe an unusually high number of Pv infections in febrile Duffy-negative Africans in Dschang, Cameroon (177 of 500 outpatients), as compared with Santchou (two of 400 outpatients) and Kye'-Ossi (two of 101 outpatients), other areas in Cameroon. In the discussion, we speculate on the possible reasons why Dschang might account for the unusually large numbers of Pv infections in Duffy-negative individuals living there.Anticoagulation plays a major role in reducing the risk of systematic thrombosis in patients with severe COVID-19. Serious hemorrhagic complications, such as intracranial hemorrhage, have also been recognized. However, intra-abdominal hemorrhage is under-recognized because of its rare occurrence, despite high mortality. link= MEK phosphorylation Here, we discuss two cases of spontaneous iliopsoas hematoma (IPH) likely caused by anticoagulants during the clinical course of COVID-19. We also explored published case reports to identify clinical characteristics of IPH in COVID-19 patients. The use of anticoagulants may increase the risk of lethal IPH among COVID-19 patients becsuse of scarce data on optimal dosage and adequate monitoring of anticoagulant effects. Rapid diagnosis and timely intervention are crucial to ensure good patient outcomes.Management of patients with severe or critical COVID-19 is mainly modeled after care for patients with severe pneumonia or acute respiratory distress syndrome (ARDS) from other causes, and these recommendations are based on evidence that often originates from investigations in resource-rich intensive care units located in high-income countries. Often, it is impractical to apply these recommendations to resource-restricted settings, particularly in low- and middle-income countries (LMICs). We report on a set of pragmatic recommendations for acute respiratory failure and mechanical ventilation management in patients with severe/critical COVID-19 in LMICs. We suggest starting supplementary oxygen when SpO2 is persistently lower than 94%. We recommend supplemental oxygen to keep SpO2 at 88-95% and suggest higher targets in settings where continuous pulse oximetry is not available but intermittent pulse oximetry is. We suggest a trial of awake prone positioning in patients who remain hypoxemic; however, this requibecause of aerosolization risk.Information about factors potentially favoring the spread of SARS-CoV-2 in rural settings is limited. MEK phosphorylation Following a case-control study design in a rural Ecuadorian village that was severely struck by the pandemic, SARS-CoV-2 RNA were detected by real-time PCR in swabs obtained from inner and upper walls in 24/48 randomly selected latrines from case-houses and in 12/48 flushing toilets from paired control-houses (P = 0.014; McNemar's test). link2 This association persisted in a conditional logistic regression model adjusted for relevant covariates (OR 4.82; 95% CI 1.38-16.8; P = 0.014). In addition, SARS-CoV-2-seropositive subjects were more often identified among those living in houses with a latrine (P = 0.002). Latrines have almost five times the odds of containing SARS-CoV-2 RNA than their paired flushing toilets. Latrines are reservoirs of SARS-CoV-2 RNA, and it cannot be ruled out that latrines could contribute to viral transmission in rural settings. Frequent disinfection of latrines should be recommended to reduce the likelihood of fecal contamination.New studies of COVID-19 are constantly updating best practices in clinical care. link2 However, research mainly originates in resource-rich settings in high-income countries. Often, it is impractical to apply recommendations based on these investigations to resource-constrained settings in low- and middle-income countries (LMICs). We report on a set of pragmatic recommendations for tracheostomy, discharge, and rehabilitation measures in hospitalized patients recovering from severe COVID-19 in LMICs. We recommend that tracheostomy be performed in a negative pressure room or negative pressure operating room, if possible, and otherwise in a single room with a closed door. We recommend using the technique that is most familiar to the institution and that can be conducted most safely. We recommend using fit-tested enhanced personal protection equipment, with the fewest people required, and incorporating strategies to minimize aerosolization of the virus. For recovering patients, we suggest following local, regional, or national hospital discharge guidelines. link3 If these are lacking, we suggest deisolation and hospital discharge using symptom-based criteria, rather than with testing. We likewise suggest taking into consideration the capability of primary caregivers to provide the necessary care to meet the psychological, physical, and neurocognitive needs of the patient.Giardia intestinalis is one of the most common causes of parasite-induced diarrhea, abdominal pain, flatulence, and malabsorption. Yet, data on the epidemiology of G. intestinalis infections in North Africa are limited. The purpose of this study was to carry out a retrospective survey on the level of intestinal parasitism with a particular emphasis on G. intestinalis in children and adults in Algiers, Algeria. A total of 2,054 individuals from outpatient clinics or hospitalized at Beni-Messous University Hospital of Algiers undergoing stool microscopy for ova and parasites were included. The overall parasite infection rate was 28%. In the 567 parasite-positive samples, Blastocystis was found most frequently (57.3%), followed in frequency by Endolimax nana (41.0%), Entamoeba histolytica/dispar (19.6%), G. MEK phosphorylation link3 intestinalis (17.1%), Entamoeba coli (13.9%), Chilomastix mesnili (1.0%), Iodamoeba bütschlii (0.7%), Entamoeba hartmanni (0.5%), and Cryptosporidium spp. (0.2%). Intestinal parasites were generally more common in adults than in children, except for Giardia, which was more common in children (P = 0.0001). Giardia infection was independent of gender (P = 0.94). Compared with other intestinal parasitic infections, clinical manifestations, such as abdominal pain (P = 0.28) and diarrhea (P = 0.82), were found not to be significantly linked to Giardia infection. In conclusion, G. intestinalis is common in individuals referred to the University Hospital of Beni-Messous with digestive symptoms, particularly so in children. However, in our study, intestinal symptoms appeared not to be more linked to Giardia than to other intestinal parasites.
