Partial life histories for 15 species and two subspecies of Afrotropical Celaenorrhinini (Hesperiidae: Pyrginae) are described and illustrated: Celaenorrhinus plagiatus Berger, C. undescribed nr. dargei Berger, C. proxima proxima (Mabille), C. proxima maesseni Berger, C. zanqua Evans, C. humbloti (Mabille), C. sanjeensis Kielland, C. galenus opalinus Butler, C. galenus biseriata Butler, C. handmani Collins & Congdon, Eretis umbra maculifera Mabille & Boullet, E. lugens (Rogenhofer), Sarangesa phidyle (Walker), S. motozi (Wallengren), S. haplopa Swinhoe, S. maculata (Mabille) and Triskelionia compacta (Evans). The published information on other species of the tribe is summarised, and generalisations are made for the tribe in Africa. All species of Celaenorrhinus, Eretis and Sarangesa spp. reared to date use Acanthaceae as food plants, but T. compacta feeds on a Fabaceae and Ortholexis hollandi Druce feeds on an Apocynaceae. Three groups of Celaenorrhinus spp. are recognised based on their pupae: Group 1 having brown pupae with cephalic projections, Group 2 having green pupae, with no cephalic projections, and a very long proboscis sheath, and a third group based on published illustrations of the life history of C. mokeezi (Wallengren), in which the pupa is generally covered with white powder, and has just a short blunt frontal projection. Loxolexis Karsch is returned to synonomy with Katreus Watson, stat.rev. and Ortholexis Karsh stat rev. is reinstated for the species which had been placed in Loxolexis: O. holocausta (Mabille) comb. nov., O. dimidia (Holland) comb. nov. and O. hollandi Druce comb. rev.

AimsMyeloid neoplasms occur in the setting of chronic lymphocytic leukaemia (CLL)/CLL-like disease. The underlying pathogenesis has not been elucidated.MethodsRetrospectively analysed 66 cases of myeloid neoplasms in patients with CLL/CLL-like disease.ResultsOf these, 33 patients (group 1) had received treatment for CLL/CLL-like disease, while the other 33 patients (group 2) had either concurrent diagnoses or untreated CLL/CLL-like disease before identifying myeloid neoplasms. The two categories had distinct features in clinical presentation, spectrum of myeloid neoplasm, morphology, cytogenetic profile and clinical outcome. Compared with group 2, group 1 demonstrated a younger age at the diagnosis of myeloid neoplasm (median, 65 vs 71 years), a higher fraction of myelodysplastic syndrome (64% vs 36%; OR: 3.1; p<0.05), a higher rate of adverse unbalanced cytogenetic abnormalities, including complex changes, −5/5q- and/or −7/7q- (83% vs 28%; OR: 13.1; p<0.001) and a shorter overall survival (median, 12 vs 44 months; p<0.05).ConclusionsMyeloid neoplasm in the setting of CLL/CLL-like disease can be divided into two categories, one with prior treatment for CLL/CLL-like disease and the other without. CLL-type treatment may accelerate myeloid leukaemogenesis. The risk is estimated to be 13-fold higher in patients with treatment than those without. The causative agent could be attributed to fludarabine in combination with alkylators, based on the latency of myeloid leukaemogenesis and the cytogenetic profile.

Comparative Description

1. The life history of N. battus is described, and a comparative description of the life history of N. filicollis is given.2. The life histories of these two species are compared with those of N. spathiger and N. helvetianus, two closely related species, and are shown to follow the same basic pattern, with minor variations in timing which appear to be specific in nature, and not related to differences in culture methods or host species.3. The pathogenesis of Nematodirus species is discussed and related to the migration of larvae into the intestinal mucosa during development.

Since 1860, in which year De Bary published his great work Die Mycetozoen, the investigation of the life-history of members of the Mycetozoa has aroused a considerable amount of interest, and a great deal of important research has been carried out in this connection. The group of organisms is particularly interesting, because it lies on the borderline between plant and animal kingdoms, and it is very possible that a detailed investigation of several species of the Mycetozoa might be of considerable assistance in elucidating certain obscure points in the life-histories of higher members of both the great natural groups. The term “Mycetozoa,” which we owe to De Bary, will be used throughout in preference to the older term “Myxogastres” invented by Fries (32, p. 2), and that of “Myxomycetes” first employed by Link (32, p. 2). “Mycetozoon,” or “fungus-like animal,” is a very appropriate description of a member of the group, since during part of its life-history it exhibits distinctly animal-like characters, and the individuals move rapidly by means of flagella, whilst later, during the development of the sporangium, a plant-like form is assumed. The combination of plant and animal characters has given rise to much discussion as to the position of the Mycetozoa in plant or animal kingdom, and the group has been claimed by both zoologists and botanists.

BACKGROUND: The uterine junctional zone is the inner part of the myometrium. Dysfunction of the zone may underlie the pathogenesis of adenomyosis and its clinical manifestations, while biometric characteristics of the zone are currently considered as promising early diagnostic criteria for this disease. Adenomyosis has traditionally been associated with parity and intrauterine interventions, primarily in older patients. However, modern imaging tools often allow diagnosing the disease in young patients with infertility and an unburdened gynecological history. It is assumed that the detection of changes in the structure and function of the uterine junctional zone in adenomyosis can be the basis for predicting fertility outcomes and complications of pregnancy, as well as for the development of promising therapeutic strategies at the pregravid stage. AIM: The aim of this study was to assess the influence of biometric characteristics of the uterine junctional zone on pregnancy outcomes, depending on the parity and intrauterine interventions in patients with adenomyosis. MATERIALS AND METHODS: This prospective study included 102 patients aged 2239 years old with ultrasound features of adenomyosis who were going to conceive. The patients were divided into two groups: Group 1 (n = 58) consisted of nulliparous patients with no history of previous intrauterine interventions, and Group 2 (n = 44) comprised multipara women with a history of labor and / or intrauterine interventions. Using magnetic resonance imaging, we evaluated minimal, average and maximal junctional zone thicknesses, junctional zone deferential and a ratio of junctional zone thickness to myometrium thickness. Thresholds of biometric characteristics of the uterine junctional zone for adverse pregnancy outcomes were estimated. RESULTS: The frequencies of pregnancy and retrochorial hematoma in patients of Groups 1 and 2 in the first trimester of pregnancy did not differ significantly and amounted to 43.1% and 38.6%, 13.8% and 22.7%, respectively, p 0.05. Adverse pregnancy outcomes were diagnosed in 63.8% of patients in Group 1 and in 68.2% of patients in Group 2, p 0.05. In Group 1, the frequency of retrochorial hematoma depended on the initial junctional zone deferential, as well as on the initial average and maximal junctional zone thicknesses, junctional zone deferentials and ratios of junctional zone thickness to myometrium thickness, which, with an adverse pregnancy outcome, were 1.72.5 times higher than those in patients with a favorable outcome, p 0.05. In Group 2, adverse pregnancy outcomes were recorded with significantly higher values of average and maximal junctional zone thicknesses and junctional zone deferential. ROC curves were constructed using data of logistic regression analysis based on biometric characteristics of the uterine junctional zone to predict spontaneous abortion and infertility in patients with adenomyosis. CONCLUSIONS: Fertility outcomes in patients with adenomyosis depend on a complex of biometric characteristics of the uterine junctional zone as determined by magnetic resonance imaging.

Due to their intricate life histories and the unique wing patterns and colouring the butterflies of the genus Chrysoritis are of significant conservation and aesthetic value. Thisoverview probes into practical examples of butterfly life history research applicable to environmental management of this relatively well-known invertebrate group in South Africa. Despite the pioneer work on life histories of Chrysoritis in the past, more should be done to understand the life history of the butterflies in the wild, especially their natural host plants and the behaviour of adults and larvae. A system of voucher specimens of host plants should be introduced in South Africa. Although various host plant species in nature are used by the members of Chrysoritis, including the Chrysoritis chrysaor group, the choice of these in nature by each species is significant for conservation management and in the case of Chrysoritis aureus perhaps even as a specific characteristic.A revision of the ant genus Crematogaster will benefit the conservation management of Chrysoritis species since some of these ant species may consist of a number of specieswith much more restricted distributions than previously thought. Rigorous quantified tudies of population dynamics of Chrysoritis butterflies are absent and the introductionof such studies will benefit conservation management of these localised butterflies extensively.

Recent studies indicated a high prevalence of hyperglycemia in non-diabetic patients presenting with acute coronary syndrome (ACS). However, the threshold of admission glucose (AG) as a predictor of adverse events in ACS is unclear. Objective The aim of this study was to assess the threshold of admission glucose (AG) as a predictor of adverse events including Major Acute Cardiac Events (MACE) and mortality, during the first week of admitting patients presenting with ACS. Material and Methods The data of 551 patients with ACS were extracted and evaluated. Patients were stratified according to their blood glucose on admission into three groups: group 1: <7 mmol/L (n = 200, 36.3%) and group 2: >7 mmol/L and <15 mmol/L (n = 178, 32.3%) and group 3: ≥15 mmol/L (n = 173, 31.4%). Stress hyperglycemia was arbitrarily defined as AG levels > 7 mmol/L (group 2 and 3). Patients with ACS were sub-divided into two groups: patients with unstable angina (UA, n = 285) and those with ST segment elevation myocardial Infarction (STEMI, n = 266) and data were analyzed separately using multiple regression analysis. Results The mean age of patients was 59.7 ± 14.8 years and 63% were males. The overall mortality in the population was 8.5% (5.4% in STEMI and 3.1% in UA) patients. In STEMI patients, the odds ratio of stress hyperglycemia as predictor of mortality in group 3 compared with group 1 was 3.3 (CI 0.99-10.98, P < 0.05), while in group 2 compared with group 1 was 2.4 (CI: 0.75-8.07, P = 0.065) after adjustment for age and sex. Similarly, in UA patients, the odds ratio of stress hyperglycemia in group 3 compared with group 1 was 2.7 (CI 0.37-18.98, P < 0.05), while in group 2 compared with group 1 was 2.4 (CI: 0.4-15.2, P = 0.344) after adjustment for age and sex. The incidence of more than 2 MACE in both STEMI and UA patients was higher in group 3 compared with the other two groups. Regression analysis showed that history of DM, high level of LDL cholesterol, high level of HbA1c, and anterior infarction were significant predictors of adverse events while other risk factors such as BMI, history of hypertension and smoking were of no significance. Conclusion This study indicates that the stress hyperglycemia on admission is a powerful predictor of increased major adverse events and hospital mortality in patients with acute coronary syndrome.

Abstract The aim of this study was to evaluate the results of an algorithm that was created to prevent coronavirus disease-2019 (COVID-19) transmission during the management of children with burns in a tertiary pediatric burn center. Children admitted to the burn center between May 2020 and November 2020 were prospectively evaluated for cause, burn depth, total body surface area (TBSA), length of stay, symptoms suggesting COVID-19, suspicious contact history, history of travel abroad, and COVID-19 polymerase chain reaction (PCR) test results. Patients were divided into two groups: unsuspected (Group 1) and suspected (Group 2), depending on any history of suspicious contact, travel abroad, and/or presence of symptoms. A total of 101 patients were enrolled in the study, which included 59 boys (58.4%) and 42 girls (41.6%). Group 1 included 79 (78.2%) patients, and Group 2 consisted of 22 (21.8%) patients. The most common cause of the burns was scald injuries (74.2%). The mean age, TBSA, and length of stay were 4.5 years, 12.0%, and 13.2 days, respectively. Four patients (3.9%) had a positive PCR test (two patients in each group). Comparing groups, males were more commonly found in Group 2 (p=0.042), but no differences were found for the other variables. No patients or burn center staff members developed COVID-19 during the course of hospitalization. In conclusion, every child should be tested for COVID-19 upon admission to a burn unit, and a modified algorithm should be constructed for the handling and management of pediatric burn patients.

Aim    To analyze associations between levels of the inflammatory marker, growth differentiation factor 15 (GDF-15), and echocardiographic indexes in CHF patients with mid-range and preserved left ventricular ejection fraction (LV EF) depending on the history of myocardial infarction (MI).Material and methods    This study included 34 CHF patients with preserved and mid-range LV EF after MI (group 1, n=19) and without a history of MI (group 2, n=15). Serum concentration of GDF-15 was measured with enzyme immunoassay (BioVendor, Czech Republic). Statistical analysis was performed with STATISTICA 10.0.Results    Patients of the study groups were age-matched [62 (58;67) and 64 (60;70) years, p=0.2] but differed in the gender; group 1 consisted of men only (100 %) whereas in group 2, the proportion of men was 53.3 % (p=0.001). Median concentration of GDF-15 was 2385 (2274; 2632.5) and 1997 (1534;2691) pg/ml in groups 1 and 2, respectively (p=0.09). Patients without MI showed a moderate negative correlation between LV EF and GDF-15 concentration (r= – 0.51, p=0.050) and a pronounced correlation between GDF-15 and LV stroke volume (r= –0.722, p=0.002). For patients after MI, a correlation between the level of GDF-15 and the degree of systolic dysfunction was not found (р>0.05).Conclusion    Blood concentration of the inflammatory marker, GDF-15, correlates with LV EF and stroke volume in CHF patients with preserved or mid-range LV EF and without a history of MI while no such correlations were observed for patients with a history of MI.

Introduction: Hyperthyroidism increases the basal metabolic rate and affects most systems in the body. Patients with hyperthyroidism have been shown to have a higher incidence of ischemic stroke. There is a paucity of information regarding its effects on the short-term outcomes of patients admitted with ischemic stroke. Hypothesis: Hyperthyroidism is associated with worse in-hospital outcomes in patients admitted for ischemic stroke. Methods: We queried the National Inpatient Sample to identify adult patients(aged 18 and above) admitted for ischemic stroke between January 2011 and December 2014. We compared those with a history of hyperthyroidism (group 1) and thyrotoxicosis on admission (group 2) with the rest of the patients (group 3). The main outcome was in-hospital mortality. Secondary outcomes included the length of hospital stay and cost of hospitalization. We used the logistic regression model and adjusted for baseline characteristics and co-morbidities. Results: There were 643,786 patients in the study, 0.44% had a history of hyperthyroidism, and 0.01% had thyrotoxicosis at the time of presentation. The odd of mortality in group 1 compared to group 3 was 0.89, 95% CI 0.75-1.05, p=0.16 while in group 2 compared to group 3, it was 2.42, 95% CI 1.29-4.52, p<0.006. The mean length of stay was also longer in group 2 with a mean difference of 8.06, 95% CI 4.74 - 11.39, p<0.0001. Conclusion: From the study, there was no significant difference in in-hospital mortality between patients with previously diagnosed hyperthyroidism and those without diagnosed hyperthyroidism. Patients who had thyrotoxicosis on admission, on the other hand, had worse outcomes compared to patients without thyrotoxicosis.
