Clinical Outcomes Associated with Amoxicillin Treatment for Acute Otitis Media in Children.

Acute otitis media (AOM) is the most common reason children are prescribed antibiotics. Bacteria that produce beta-lactamase are an increasingly frequent cause of AOM and may be resistant to amoxicillin, the currently recommended treatment for AOM. We aimed to evaluate the clinical outcomes of children treated with amoxicillin for AOM and assessed whether outcomes vary by infecting pathogen or beta-lactamase production. 205 children 6-35 months old diagnosed with AOM and prescribed amoxicillin were included. Bacterial culture and qualitative multiplex real-time polymerase chain reaction were performed on nasopharyngeal swabs collected at enrollment. Parents completed surveys assessing symptoms, antibiotic adherence, and potential adverse events. The primary outcome was treatment failure with amoxicillin. Secondary outcomes included recurrence, symptom improvement, resolution, and adverse drug events (ADE). 8 children (5.4%) experienced treatment failure and 14 (6.8%) had recurrence. By day 5, 152 (74.1%) children had symptom improvement and 97 (47.3%) had resolution. Parents reported ADE for 56 (27.3%) children. Among 149 children who did not take any amoxicillin before enrollment, 98 (65.8%) had one or more beta-lactamase-producing bacteria. Common bacterial otopathogens were Moraxella catarrhalis (79, 53.0%), Streptococcus pneumoniae (51, 34.2%), Haemophilus influenzae (30, 20.1%), and Staphylococcus aureus (21, 14.1%). Treatment failure did not differ between children that did (5, 5.1%) and did not (3, 5.9%) have beta-lactamase-producing otopathogens (p = .05). Among children diagnosed with AOM treated with amoxicillin, treatment failure was uncommon and did not differ by pathogen or beta-lactamase production. These data support guidance recommending amoxicillin despite an increasing prevalence of beta-lactamase-producing bacteria.

Approaching Equality? Media Treatment of Male and Female Members of Presidential Cabinets in a Cross-Country Comparison

Abstract Generalizability of extant findings about media treatment of women in politics is uncertain because most research examines candidates for the legislature or heads of government, and little work moves beyond Anglo-American countries. We examine six presidential cabinets in Costa Rica, Uruguay, and the United States, which provide differing levels of women’s incorporation into government. These cases permit us to test hypotheses arguing that differences in media treatment of men and women cabinet ministers will decrease as women’s inclusion in government expands, and that media treatment of women is more critical when women head departments associated with masculine gender stereotypes. Results show that greater incorporation of women into government is associated with fewer gendered differences in media coverage, tone of minister coverage is more favorable for women who hold masculine stereotyped portfolios, and that the media does present qualifications of women cabinet ministers.

The The Effect of Types Planting Media and the Growth Regulatory Substances of Sprouts Extract on the Growth and Yield of Long Bean (Vigna unguiculata L.)

Long bean production in East Java has declined in the last three years because of the decreased soil fertility and the failure of pod formation. The addition of organic matter to the soil planting medium and spraying ZPT bean sprout extract are some efforts to increase the supply of nutrients and overcome flower fall. This study aimed to determine the interaction between the treatment of the planting media and ZPT of bean sprout extract toward growth and yield of long bean plants. The study was conducted factorially using a completely randomized design (CRD) in 3 replications. The first factor is the type of planting medium namely M0: soil; M1: soil+ compost; M2: soil+ chaff charcoal; M3: soil+ cocopeat. The second factor was the concentration of ZPT bean sprout extract, namely T0 control; T1: 10%; T2: 20%; T3: 30%. There was a very significant interaction between the treatment of the planting media and the bean sprout extract ZPT on the variable number of pods per plant and wet weight of pods per plant. The best treatment was the combination of the type of soil and compost growing media with ZPT bean sprout extract 20%. The main effect of the type of planting media treatment showed that the results were not significantly different for all observed variables. The ZPT treatment of bean sprout extract significantly affected the variables of flowering age, harvest age, and pod length per plant, the best treatment was the concentration of ZPT bean sprout extract 20%.

Sorption Treatment of Aqueous and Organic Media to Remove Tributyl Phosphate and Acidic Products of Its Decomposition

The effect of planting media and seed soaking on the growth of true shallot (Allium ascalonicum L.) seeds

The Shallots are one of the commodities in high demand in Indonesia. One method for increasing shallot growth is to use good planting media and seed treatment. The purpose of this experiment was to see what effect planting media and seed soaking had on the growth of shallot TSS (Allium ascalonicum L.). A factorial randomized block design (RAK) with three replications was used in the experiment. The first factor is the planting media, which is divided into three levels: M1 (cocopeat), M2 (zeolite), and M3 (sand). The second factor is seed soaking, which has three levels: no soaking (P0), warm water 35°C 30 minutes (P1), and plain water 24 hours (P2). When compared to sand planting media, the treatment of cocopeat and zeolite planting media had a significant effect on germination capacity and fresh weight. Soaking shallot seeds in warm water at 35°C for 30 minutes and plain water for 24 hours had a significant effect on germination, plant height, number of leaves 7-21 DAT, fresh weight, and dry weight of shallots compared to not soaking. There is a significant interaction that affects the percentage of germination. However, there was no significant interaction between plant height, number of leaves, fresh weight, and dry weight of shallots and various planting media and seed soaking.

Manipulating larval rearing media to optimise mass production of the blow fly Calliphora vicina (Diptera: Calliphoridae)

AbstractThe oviparous blow fly Calliphora vicina has shown potential as a managed pollinator to support honeybee (Apis mellifera) usage in Australian horticulture. A series of three laboratory‐based studies reared newly hatched larvae of C. vicina on meatmeal with varying amounts of either whole egg powder, whole eggs (including shells), bran flakes, brewer's yeast, fish paste or milk powder. The objective was to determine the best larval media for quick and efficient production of adult flies in a mass‐rearing environment. Pure meatmeal or meatmeal with only brewer's yeast added were the least productive media. Larvae fed meatmeal with either 10% or 20% whole dried egg powder had the fastest development to pupae, the highest pupation rate, the heaviest pupae and the highest subsequent adult eclosion. Larval media containing fish paste had the highest survival through to adult emergence (>85%) of all the media treatments, which suggests that this ingredient is of value when mass rearing C. vicina. In addition, newly hatched larvae (n = 50) were reared on varying amounts of media (i.e., 4, 2, 1, 0.5, 0.25 and 0.125 g per larvae) to determine the minimum amount of media required to produce adults. Reductions in media per larvae resulted in smaller pupae and adults that emerged with no subsequent reduction in adult eclosion, indicating the adaptability of this fly to food deprivation. Replacing whole egg powder with whole eggs reduces the costs of rearing C. vicina larvae significantly. In order to rear 1 million adult C. vicina, these studies showed that 0.5 g of media per larvae is sufficient to produce high numbers of pupae with >95% adult eclosion. Although larval development and pupation are optimal on media containing whole egg powder, its recent rapid rise in costs makes it far less economical compared with the use of discarded whole eggs from egg producers. Sourcing of seafood waste could also reduce media costs and improve production of C. vicina. The costs of each media required to realise 1 million adult C. vicina are between $540 and $1900 depending on the media ingredients.

Pengaruh Penambahan Kombinasi Benzyl Amino Purine dan Pepton Terhadap Pertumbuhan Planlet Anggrek Cattleya sp.

Orchidaceae is one type of ornamental plant which is a leading commodity. Cattleya sp. are a potential type of orchid in terms of productivity and high economic value. Conventional Cattleya sp. cultivation is considered less effective because the number of tillers produced is very limited. Therefore an alternative Cattleya sp. cultivation is needed using plant tissue culture techniques or in vitro. The research objective is to determine the effect of the addition of the combination of BAP and peptone on the growth of orchid plantlets Cattleya sp. This experiment was conducted in the Plant Tissue Culture Laboratory of the Faculty of Mathematics and Natural Science Universitas Negeri Malang from August to November 2016. This study used a completely randomized design. The treatment was in the form of ½ MS medium added with a combination of Benzyl Amino Purine (BAP) and Peptone. The explant used was the protocorm of Cattleya sp. 1 month old with a size of ± 0.5 cm. Protocorm was inoculated as much as 10 protocorm on media treatment. The results showed that Peptone can affected the growth of Cattleya sp. plantlets. The ½ MS treatment with the addition of peptone produced the highest number of leaves and the highest plantlet height, while the ½ MS treatment without the addition of BAP and peptone produced the highest number of roots.

RESPON PERTUMBUHAN DAN HASIL TOMAT CERI PADA BERBAGAI MEDIA TANAM DI LAHAN HOLTIKULTURA, GRESIK

Cherry tomatoes (Solanum Lycopersium Mill) are horticultural crops that are rich in vitamins A and C. Cherry tomatoes are one of the prospective agricultural products in Indonesia and have a higher economic value. Planting media is defined as a place where plants live according to their life requirements. The combination of growing media has an effect on the growth and yield of cherry tomato plants. Charcoal husks or roasted husk charcoal can be used as a planting medium and has light characteristics, namely 0.2 kg per liter of rice, coarse texture so it has high air circulation. Besides charcoal, goat manure husks can also be used as a mixture of planting media. Goat manure contains nitrogen nutrients which are useful during plant growth. The aim of this study was to examine the response and differences in media treatment on the growth of cherry tomatoes. This study used a single factor Completely Randomized Design (CRD) with Goat Manure, Husk and soil as the medium which resulted in 7 treatments. Each treatment was repeated four (4) times, so that 28 experimental units were obtained, there were 224 plants. Obtained observational data will be analyzed using Analysis of Variance (Anova). If there is a significant difference, it will be continued with the 5% BNT Advanced Test. The results showed that there was no significant difference in the application of various growing media on the growth and yield of cherry tomato plants.

Watchful Waiting Strategy in the Treatment of Acute Otitis Media in Children

Background: Acute otitis media (AOM) is a common issue among children, often requiring antibiotic treatment. It is crucial to explore methods for the rational use of antibiotics. This study aimed to assess the effectiveness of the watchful waiting approach in treating children aged 6 months to 18 years with mild to moderate AOM. Methods: This prospective quasi-experimental study was conducted on 100 children with mild to moderate AOM. All patients, except those in severe or critical conditions, were placed on the watchful waiting strategy. A follow-up was conducted after 48 - 72 hours. If symptoms had improved, the watchful waiting approach continued. If medication was necessary for various reasons, these reasons were documented. Subsequently, children who completed the watchful waiting strategy were compared to those who received antibiotics. The collected data were analyzed using chi-square and t-tests in SPSS Statistics for Windows (version 16.0). Results: In this study, 59 patients (59%) were treated with the watchful waiting approach; nevertheless, 41 patients (41%) received antibiotics. The presence or absence of postnasal discharge showed a significant difference between the two groups (P = 0.001). No significant differences were observed between the two groups regarding fever (P = 0.066), enlarged tonsils (P = 0.740), snoring (P = 0.252), and bilateral involvement of the tympanic membrane (P = 0.313). Conclusions: Based on the results, the watchful waiting strategy is a cost-effective method for children aged over 6 months with mild to moderate symptoms, provided that parents cooperate fully. Clinicians should be cautious and consider alternative treatments if postnasal discharge is present, as it might indicate a higher likelihood of treatment failure with the watchful waiting approach.

“Pridnestrovie for Peace”: Accounting for Transnistrian Divergence from the Russian Position vis-à-vis the Russo-Ukrainian War

Despite historical and ongoing reliance on Russia and an enduring pro-Russian stance, the official narrative of the Pridnestrovian Moldavian Republic (Transnistria) regarding the Russian invasion of Ukraine in February 2022 has been surprisingly neutral. This article seeks to establish a typology of the various reasons for this divergence, looking at geographical, demographic, socio-cultural, historical, economic and military factors, as well as the extenuating influence of the preexisting conflict with Moldova. These factors combine to incline the Transnistrian population and leadership toward peace and thus demotivate an overtly negative media treatment of Ukraine in the context of the War. Given limited scholarship on the topic and the opacity of Transnistrian governance, video reports from the state-affiliated channel TSV are employed as primary sources to evidence and exemplify the various factors determining the Transnistrian position on the Russo-Ukrainian War. The article concludes by challenging the view of Transnistria as a passive Russian puppet, and proposes that the region’s unusual status and location, while limiting, also lend it a certain flexibility in its media narratives and foreign policy.

Этиология, диа гностика, осложнения и лечение острого среднего отита у детей. Современный взгляд на проблему

The article delves into the etiology, clinical manifestation, diagnosis, and treatment of acute otitis media (AOM), along with measures for preventing its complications. AOM is characterized by the rapid onset of symptoms indicative of inflammation in the middle ear. The paper examines AOM incidence rates across different countries, including Russia, highlighting the significance of this health issue. Various factors can contribute to the development of AOM, such as anatomical features of the middle ear, the cellular biology patterns of the nasopharynx, and variations in immune responses to microbial invasions. The condition is commonly associated with viral and bacterial pathogens, as well as genetic predisposition; however, bacteria are generally considered the primary causative agents. The article also addresses therapeutic approaches and the concern of overdiagnosis, which can lead to the excessive use of antibiotics and subsequent resistance. A retrospective analysis of 90 outpatient records was conducted, focusing on patients who received analgesic ear drops during the pre-perforated stage of AOM. Findings indicate that a combination drug containing lidocaine and phenazone was frequently prescribed in cases of recurrent AOM and for referrals to an otorhinolaryngologist within the initial two days of disease onset, particularly for patients with bilateral AOM. The importance of prompt diagnosis and appropriate treatment of AOM is underscored, as well as the necessity for preventive measures to decrease incidence rates. These insights can be highly beneficial for practitioners and specialists in the field of otorhinolaryngology.

Homeopathy in the treatment of chronic suppurative otitis media: A review

ВОЗМОЖНОСТИ КОМПЛЕМЕНТАРНОЙ ТЕРАПИИ ПРИ ОСТРОМ СРЕДНЕМ ОТИТЕ У ДЕТЕЙ

The decision to prescribe a drug and its choice pose a difficult task for the physician, especially when the question arises whether to recommend systemic antibiotic therapy. A clinical case of treatment of acute otitis media in a pediatric patient is presented — a situation often encountered in outpatient practice, but atypical. A set of sequential steps is proposed as an algorithm for clinical thinking. The difficulties of differentiating the forms of otitis media are shown. An analysis of clinical and anamnestic data was carried out in conjunction with the results of additional examination methods. The place, contribution and role of bioregulatory drugs are substantiated. The effectiveness and safety of their use in the complex therapy of acute otitis media in accordance with clinical recommendations is demonstrated. The possibility of using the drugs Engystol®, Traumeel S®, Lymphomyosot® along with traditional methods of treatment for acute otitis media in children is shown.

Brain Metastases Are Regulated by Immuno-inflammatory Signaling Pathways Governed by STAT3, MAPK and Tumor Suppressor p53 Status: Possible Therapeutic Targets.

Brain metastasis (BM) is a complex multi-step process involving various immune checkpoint proteins. Mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases 1/2 (ERK1/2), and signal transducer and activator of transcription 3 (STAT3) are implicated in tumorigenesis and are critical upstream regulators of Programmed Death Ligand 1 (PD-L1), an immunotherapy target. Tumor suppressor p53, dysregulated in cancers, regulates STAT3 and ERK1/2 signaling. This study examined the roles of STAT3, MAPK and p53 status in BM initiation and maintenance. Twenty-six BM, with various primary malignancies, were used (IRB-approved) to determine mutant p53 (p53mt), pSTAT3Tyr705, pERK1/2Thr202/Tyr204, and PD-L1 expression using immunohistochemistry. cDNA microarray was used for gene expression analysis. Brain-metastatic breast cancer cells (MDA-MB-231) were treated with STAT3 (NSC74859) or MAPK/ERK1/2 (U0126) inhibitors in regular or astrocytic media. ERK1/2 pathway was assessed using western blotting, and cell proliferation and migration were determined using MTT and scratch-wound assays, respectively. pSTAT3Tyr705 and pERK1/2Thr202/Tyr204 were expressed at tumor margins, whereas p53mt and PD-L1 were uniformly expressed, with significant overlap between expression of these proteins. Gene expression analysis identified alterations in 18 p53- and 32 STAT3- or MAPK-associated genes contributing to dysregulated immune responses and cell cycle regulation. U0126 and NSC74859 reduced pERK1/2Thr202/Tyr204 expression. Cell proliferation decreased following each treatment (p≤0.01). Migration stagnated following U0126 treatment in astrocytic media (p≤0.01). Activation of STAT3 and ERK1/2 promotes BM and provides compelling evidence for use of STAT3, ERK1/2 and p53 status as potential immunotherapeutic targets in BM.

Depicting Migrants' Life in Moroccan Newspapers

Sub-Saharan migrants in Morocco have become a part and partial issue in Moroccan newspapers as their number has enormously risen. Media, in general, brings to the public most of the images, data, and facts about migrants. For this reason, the media's treatment of migration generates currents of opinion and attitudes towards these people. Furthermore, since it has been massively highlighted in Moroccan newspapers, many people would interpret migration from Sub-Saharan countries primarily from the messages from the Media. Therefore, the readers' images would be influenced by how the issue is depicted and portrayed in newspapers. This article aims to shed light on the way Moroccan newspapers deal with the issue of migration towards Morocco from Sub-Saharan countries and how their life was depicted after the launch of the new migration policy. With these objectives in mind, this study is based on qualitative data collection of news items and reports from four daily printed newspapers in Morocco. Relying on Content analysis has demonstrated a stereotypical misrepresentation and a slight change in topics coverage of 'black' African migrants in news narratives.

Hydrophobic sorbents based on ultrathin polymer fibers for trapping oil products

Relevance. Increasing negative effects of hydrocarbon production on aquatic ecosystems and tightening of legislative norms on discharge of oil and oil product contaminated water into marine waters. Among various methods used to remove oil from aqueous solutions the most appropriate one is adsorption method. It is explained by its high degree of purification, safety, availability, manufacturability, universality of application. Synthetic materials based on ultrafine fibers have optimal characteristics for manufacturing sorbents for oil removal on their basis. However, the large-scale application of these materials is limited by their high cost, complexity of manufacturing, which excludes the secondary use of polymers as feedstock. In this regard, there is a growing need for economically and environmentally effective hydrophobic materials for sorptive treatment of aqueous media from oil and petroleum products. Aim. To determine sorption properties of hydrophobic fibrous materials produced via pneumatic formation for use as effective hydrocarbon sorbents for liquidation of oil spills in sea and water treatment on oil production platforms. Objects. Sorbents based on polypropylene and polyethylene terephthalate ultrafine fibers. Methods. Gravimetric, spectral analysis, transmission electron microscopy, gas chromatography. Results. The paper introduces the results of investigation of sorption properties of untreated ultrafine fibers obtained by pneumatic atomization and modified by microwave radiation. The authors have carried out the comparative analysis of water absorption and the influence of contact time and acidity of the medium on the degree of sorption of samples obtained from hydrophobic polymers. Promising application of sorbents based on polypropylene ultrathin fibers for oil products extraction from aqueous media was revealed. It is established that modification reduces water absorption of polypropylene sorbents and leads to an insignificant decrease in sorption properties due to changes in the supramolecular structure of polypropylene fiber samples.
