RESUMEN
Four new subgenera in the genus Raphignathus Dugès are hereby proposed: Raphignathus (Raphignathus), subgen. nov., Raphignathus (Monoraphignathus), subgen. nov., Raphignathus (Diraphignathus), subgen. nov., and Raphignathus (Triraphignathus), subgen. nov. These subgenera are diagnosed by the number of setae on the interscutal membrane of females. A new species, R. (D.) neohecmatanaensissp. nov., is described and illustrated based on females collected from Ziziphusspina-christi Mill. (Rhamnaceae). The taxonomic status of the monotypic genus Neoraphignathus Smiley & Moser and three species (R.evidus, R.hsiufui, and R.johnstoni) are discussed. A key to world species of the family Raphignathidae is given.

BACKGROUND: Polycystic ovary syndrome (PCOS) affects up to 18% of reproductive-age females. The prevalence of obesity in PCOS patients reaches up to 80%, which is 2-fold higher than the general population. OBJECTIVE: The present study aimed to compare the effectiveness of 55 pharmacological interventions across 17 different outcomes in overweight/obese PCOS patients with hyperandrogenism manifestations for both short- and long-term follow-ups. A comprehensive literature search was performed on PubMed, Scopus, Embase, Science Direct, Web of Science, and Cochrane CENTRAL for randomized controlled trials comparing any conventional pharmacological intervention as a monotherapy or a combination in overweight/obese patients with polycystic ovary syndrome and hyperandrogenism manifestations. Extracted data included three main parameters; I. Anthropometric parameters (BMI, Waist and Hip circumferences, and Waist/HIP ratio), II. Hormonal parameters (FSH, LH, FSG, SHBG, Estradiol, Total Testosterone, Free testosterone, DHEAS, Androstenedione), and III. Metabolic parameters (Total Cholesterol, LDL-C, HDL-C, Triglycerides, Fasting glucose, Fasting glucose, HOMA-IR). Critical appraisal and risk of bias assessments were performed using the modified Jadad scale, and the overall quality of this network meta-analysis was evaluated according to the CINeMA framework. We performed both a pairwise meta-analysis and a network meta-analysis to evaluate the effect sizes with 95% CI, and we calculated the surface under the cumulative ranking curve (SUCRA) for each intervention. RESULTS: Our final search on May 15th 2021 retrieved 23,305 unique citations from searching six electronic databases. Eventually, 101 RCTs of 108 reports with a total of 8,765 patients were included in our systematic review and multi-treatments meta-analysis. 55 different interventions were included: 22 monotherapies, and 33 combinations. The two-dimensional cluster ranking of the average SUCRA values for metabolic and hormonal parameters with significant estimates revealed flutamide (77.5%, 70%; respectively) as the highest and rosiglitazone (38.2%, 26.3%; respectively) as the lowest, in terms of the overall efficacy in reducing weight and hyperandrogenism. However, cyproterone-acetate+ethinylestradiol exhibited a higher ranking in improving hormonal parameters (71.1%), but even a lower-ranking regarding metabolic parameters (34.5%). CONCLUSIONS AND RELEVANCE: Current evidence demonstrated the superiority of flutamide in improving both metabolic and hormonal parameters, and the higher efficacy of cyproterone-acetate+ethinylestradiol only in improving hormonal parameters. Nearly all interventions were comparable in female hormones, FGS, HDL, glucose, and insulin levels improvements.

BACKGROUND: Palliative care is a care option considered appropriate for those with heart failure, but is uncommon partially due to a lack of timely identification of those needing palliative care. A standard mechanism that triggers which heart failure patients should receive palliative care is not available. The Gold Standards Framework (GSF) identifies those needing palliative care but has not been investigated with heart failure patients. OBJECTIVES: To describe palliative care provided in the community and determine whether the GSF can identify heart failure patients in need of palliative care. METHODS: Descriptive study. A total of 252 heart failure patients in the community completed a demographic characteristics questionnaire, the Edmonton symptom assessment scale-revised and the Minnesota living with heart failure questionnaire. Clinical data were collected from the medical chart and the primary physician completed the GSF prognostic indicator guidance. RESULTS: Participants had a mean age of 76.9 years (standard deviation 10.9), most at New York Heart Association level III (n=152, 60%). Fewer than half received pain medications (n=76, 30%), anxiolytics (n=35, 14%), antidepressants (n=64, 25%) or sleep medications (n=65, 26%). Eight patients spoke with a psychologist or psychologist (3%). One had an advanced directive and 16 (6%) had a record of discussions with their family caregivers. Three (1%) had end-of-life discussions with their healthcare providers. Most healthcare providers responded 'no' to the 'surprise question' (n=160, 63%). Sensitivity and specificity of the gold standards framework was poor. CONCLUSIONS: Few community dwelling heart failure patients received most aspects of palliative care. The gold standards framework was not a good indicator of those who should receive palliative care.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) affects up to 30% of the population. Clinical trials have questioned the role of vitamin E in the treatment of NAFLD with or without other interventions, with still no firm conclusion reached. This study aims to examine the efficiency of vitamin E alone or combined in the management of NAFLD. METHODS: We performed a systematic literature search on PubMed, Scopus, Embase, Ovid, EBSCO host, Science Direct, Web of Science, and Cochrane CENTRAL for randomized controlled trials (RCTs) of the role of vitamin E alone or combined in NAFLD patients. Extracted manuscripts reported data on biochemical, histological, anthropometric, and metabolic outcomes. Baseline characteristics, settings, dosage, and frequency were also collected. RESEARCH: A total of 1317 patients from 15 RCTs were included in our systematic review and meta-analysis. Vitamin E was superior at improving alanine aminotransferase (ALT), aspartate aminotransferase (AST), NAFLD activity score (NAS), and fibrosis in short- and long-term follow up in the adult population, and long-term follow up in the pediatric population. Improvements in metabolic outcomes were best noticed in pediatric patients. Results from multiple regression models showed a significant association between ALT-AST levels and vitamin E dose. AST levels had a significant effect on NAS, and patients with a baseline AST > 50 IU/l showed more promising results. Changes in weight and body mass index (BMI) were strongly associated with changes in NAS. CONCLUSION: Current evidence affirms that vitamin E - whether alone or combined - improves biochemical and histological outcomes in adults and pediatric patients.
RESUMEN
Antimicrobial resistance (AMR) is a growing threat that causes over 700,000 deaths per year worldwide. The goal of the current multicenter, cross-sectional study was to identify the knowledge and practice gaps in antimicrobial stewardship among Egypt's undergraduate medical students. Nine-hundred and sixty-three participants (375 male) from 25 medical schools responded to our self-administered questionnaire. Overall, the majority of students (96%) exhibited fair/satisfactory knowledge and attitude scores towards AMR. However, the most common misconceptions were that skipping one or two antimicrobial doses does not contribute to AMR (43%) and that antimicrobials are the drug of choice for the treatment of sore throat (38.8%). About 36% of the students thought that bacteria cause common cold and influenza. In terms of practices, about 62% of the students reported taking antibiotics when they have cough or sore throat and saving the remaining antibiotic for the next time. About 48% of the students reported that when they start feeling better, they stop the antibiotic course, and 41% stated that they often/sometimes discard the remaining leftover or share the leftover antibiotics with their friends. Interestingly, males had more frequently poorer levels of knowledge than females (p = 0.02). Moreover, students in the clinical science years (p < 0.001), living in urban areas (p = 0.02) or Cairo (p < 0.01) reported better practices than their counterparts. Educational programs about antimicrobial stewardship and the role of healthcare professionals in preventing AMR should be introduced early in medical curricula. Further, active educational techniques as clinical scenarios that simulate clinical settings and interactive learning workshops would be more efficient teaching methods.

Two new species of the genus Eutetranychus Banks are described and illustrated based on adult females and males, E.spinosus sp. n. from Indigoferaspinosa Forssk (Leguminosae), E.neotransversus sp. n. from Juniperusprocera Hochst. ex Endl. (Cupressaceae), and E.palmatus Attiah, 1967 is redescribed from Washingtoniarobusta H. Wendl. (Arecaceae). Additionally, the intraspecific morphological variations within E.orientalis populations, collected from 28 various host plants and 80 different localities from six regions of Saudi Arabia from 2009 to 2017, are discussed and presented. The genus Eutetranychus is divided into two species groups based on the presence of one seta (orientalis group) or two setae (banksi group) on coxa II. In addition, seven Eutetranychus species are suggested as synonyms of E.orientalis (Klein, 1936) and E.papayensis Iqbal & Ali, 2008 is considered as species inquirenda. A key to all known species of the genus Eutetranychus is provided.
