Worker morphology of the taxon is compared with those of other Ponerinae and the similarities between them are discussed, refining the definition of character states for some diagnostic characters at the generic level, providing an identification key to the Neotropical genera, and making some adjustments to the taxonomic framework within the subfamily. Descriptions, diagnosis, character discussion, identification key, and glossary are illustrated with more than 300 images and line drawings. Open science is supported by providing access to measurement data for specimens of the new genus, a matrix of character states for all ponerine taxa evaluated in this study, and specimen data for all examined material. The new or revived combinations presented here are Pachycondylaprocidua Emery, comb. rev., Neoponeracuriosa (Mackay and Mackay), comb. nov., Leptogenysbutteli (Forel), comb. nov., and Bothroponeraescherichi (Forel), comb. nov. In addition, Leptogenysbutteli is synonymized with Leptogenysmyops (Emery), syn. nov.One of the primary threats to the goal of controlling and eventually defeating SARS-CoV-2 is that of mutation. Recognizing this, a great amount of effort and dedicated study is being given to the matter. Due to the novel coronavirus's general prevalence and rate of mutation, this is an extremely dynamic area with constant new developments. Therefore, understanding the virus's pathogenesis and how mutations affect it is crucial. This review attempts to aid in understanding the currently most important strains and what primary changes they entail in connection to more specific mutations, and how they each affect infectivity, antigen resistance, and other properties. In an attempt to maintain relevance to the time at which this paper will be published, priority has been given to variants classified by the WHO and the CDC as of Sep. 23, 2021, as "Variants of Concern". Of particular interest in B.1.1.7, B.1.351, B.1.617.2, P.1 are the mutations affecting the Spike protein and Receptor Binding Domain, as they directly affect infectivity and susceptibility to neutralization. Certain mutations (D614G, E484K, N501Y, K417N, L452R and P681R) have appeared across several different strains, often accompanied by others that may be complementary working together to confer increased infectivity, fitness, or resistance to neutralization. We anticipate that the understanding of such COVID-19 mutations will, in the near future, prove important for diagnosis, treatment development, and vaccine development.
The purpose of this study is to determine the value-based price of a COVID-19 vaccine from a societal perspective in Germany.
A decision model was constructed using, e.g., information on age-specific fatality rates, intensive care unit (ICU) costs and outcomes, and the full vaccination rate. Three strategies were analysed vaccination (with 95 % and 50 % efficacy against death), a mitigation strategy, and no intervention. The base-case time horizon was 5 years. The value of a vaccine includes savings from avoiding COVID-19 mitigation measures and productivity loss, as well as health benefits from preventing COVID-19 related mortality. The value of an additional life year was borrowed from new, innovative oncological drugs, as cancer reflects a condition with a similar morbidity and mortality burden in the general population in the short term as COVID-19.
A vaccine with a 95 % efficacy dominates the mitigation strategy strictly. The value-based price (€6,431) is thus determined by the comparison between vaccination and no intervention. The price is particularly sensitive to the full vaccination rate and the duration of vaccine protection. In contrast, the value of a vaccine with 50 % efficacy is more ambiguous.
This study yields a value-based price for a COVID-19 vaccine with 95 % efficacy, which is considerably greater than the purchasing price.
This study yields a value-based price for a COVID-19 vaccine with 95 % efficacy, which is considerably greater than the purchasing price.The COVID-19 medical diagnosis method based on individual's chest X-ray (CXR) is achieved difficultly in the initial research, owing to difficulties in identifying CXR data of COVID-19 individuals. At the beginning of the study, infected individuals' CXRs were scarce. The combination of artificial intelligence and medical diagnosis has been advanced and popular. To solve the difficulties, the interpretability analysis of AI model was used to explore the pathological characteristics of CXR samples infected with COVID-19 and assist medical diagnosis. The dataset was expanded by data augmentation to avoid overfitting. Transfer learning was used to test different pre-trained models and the unique output layers were designed to complete the model training with few samples. In this study, the output results of four pre-trained models were compared in three different output layers, and the results after data augmentation were compared with the results of the original dataset. The control variable method was used to conduct independent tests of 24 groups. Finally, 99.23% accuracy and 98% recall rate were obtained, and the visual results of CXR interpretability analysis were displayed. The network of COVID-19 interpretable diagnosis algorithm has the characteristics of high generalization and lightweight. It can be quickly applied to other urgent tasks with insufficient experimental data. At the same time, interpretability analysis brings new possibilities for medical diagnosis.Deep learning based analyses of computed tomography (CT) images contribute to automated diagnosis of COVID-19, and ensemble learning may commonly provide a better solution. Here, we proposed an ensemble learning method that integrates several component neural networks to jointly diagnose COVID-19. Two ensemble strategies are considered the output scores of all component models that are combined with the weights adjusted adaptively by cost function back propagation; voting strategy. A database containing 8 347 CT slices of COVID-19, common pneumonia and normal subjects was used as training and testing sets. Results show that the novel method can reach a high accuracy of 99.37% (recall 0.9981, precision 0.989 3), with an increase of about 7% in comparison to single-component models. And the average test accuracy is 95.62% (recall 0.958 7, precision 0.955 9), with a corresponding increase of 5.2%. Compared with several latest deep learning models on the identical test set, our method made an accuracy improvement up to 10.88%. The proposed method may be a promising solution for the diagnosis of COVID-19.The incidence of abdominal cysts in infants is 1 in 500 to 1 in 1,000 live births. Among the ovarian cysts in infants, serous cystadenoma is extremely rare with only few reported cases in the literature. Here, we report a case of a giant neonatal ovarian serous cystadenoma treated with laparoscopic cystectomy and confirmed by histopathological examination. A 27-year-old delivered a female baby with uneventful caesarean section at full term. The antenatal ultrasonography (USG) in third trimester had showed an abdominal cyst in the left side of the abdomen. Postnatal USG was suggestive of omental cyst. A contrast-enhanced computed tomography scan of the neonate showed a large cyst occupying the entire abdomen. On laparoscopic evaluation, a cystic mass filled with 500 mL of clear yellow fluid was seen in the left pelvic fossa. Left ovary could not be visualized separately. The right ovary, fallopian tubes, and uterus were normal. The entire cyst was removed and sent for histopathological examination. On gross examination, a unilocular cyst measuring 10×8×6.5 cm with a wall thickness of 0.2 cm was noted. On microscopic examination, the histomorphological features were consistent with serous cystadenoma of the ovary. There is a paucity of literature regarding pathological diagnosis of such cases and hence we report one such case.We report two cases of women with metastatic cancers to ampulla of Vater. The first was 91 years old and presented with severe anemia, due to upper gastrointestinal bleeding. She had history of renal cell cancer treated with nephrectomy 8 years ago and diagnosis confirmed to be metastasis of renal cell cancer to ampulla of Vater. The second patient was 54 years old with breast cancer, metastasis and developed obstructive jaundice; diagnosis confirmed to be breast metastasis in the ampulla of Vater. Secondary tumors of the ampulla of Vater due to breast cancer and renal cell cancer are rare findings and prognosis can be poor.A 21-year-old human immunodeficiency virus-positive male patient presented with complaints of multiple hyperpigmented verrucous papules over his perianal area. He reported having unprotected anal and oral sex with multiple male partners. On examination, superficial ill-defined perianal erosions were present. A first void urine sample and clinician-collected rectal and oropharyngeal swabs were sent for the detection of Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis , and Ureaplasma spp. Rectal swab tested positive for all the four pathogens. Oropharyngeal swab and urine samples tested positive for C. trachomatis . The patient was treated with doxycycline and moxifloxacin. This case underscores the importance of screening of men who have sex with men for possible coinfections with multiple sexually transmitted pathogens.
