Published: August 2022

OBJECTIVE
To characterize the outcomes of children with community acquired pneumonia (CAP) across 41 United States hospitals and evaluate factors associated with potentially unnecessary admissions.

METHODS
We performed a cross-sectional study of patients with CAP from 41 United States pediatric hospitals and evaluated clinical outcomes using a composite ordinal severity outcome: mild-discharged (discharged from the emergency department), mild-admitted (hospitalized without other interventions), moderate (provision of intravenous fluids, supplemental oxygen, broadening of antibiotics, complicated pneumonia, and presumed sepsis) or severe (ICU, positive-pressure ventilation, vasoactive infusion, chest drainage, extracorporeal membrane oxygenation, severe sepsis, or death). Our primary outcome was potentially unnecessary admissions (ie, mild-admitted). Among mild-discharged and mild-admitted patients, we constructed a generalized linear mixed model for mild-admitted severity and assessed the role of fixed (demographics and clinical testing) and random effects (institution) on this outcome.

RESULTS
Of 125 180 children, 68.3% were classified as mild-discharged, 6.6% as mild-admitted, 20.6% as moderate and 4.5% as severe. Among admitted patients (n = 39 692), 8321 (21%) were in the mild-admitted group, with substantial variability in this group across hospitals (median 19.1%, interquartile range 12.8%–28.4%). In generalized linear mixed models comparing mild-admitted and mild-discharge severity groups, hospital had the greatest contribution to model variability compared to all other variables.

CONCLUSIONS
One in 5 hospitalized children with CAP do not receive significant interventions. Among patients with mild disease, institutional variation is the most important contributor to predict potentially unnecessary admissions. Improved prognostic tools are needed to reduce potentially unnecessary hospitalization of children with CAP.
Improving Ventilation Rates During Pediatric Cardiopulmonary Resuscitation
Authors: Chapman Jennifer D. , Geneslaw Andrew S. , Babineau John , Sen Anita I. 
Published: August 2022

BACKGROUND
Excessive ventilation at rates of 30 breaths per minute (bpm) or more during cardiopulmonary resuscitation (CPR) decreases venous return and coronary perfusion pressure, leading to lower survival rates in animal models. A review of our institution’s pediatric CPR data revealed that patients frequently received excessive ventilation.

METHODS
We designed a multifaceted quality improvement program to decrease the incidence of clinically significant hyperventilation (≥30 bpm) during pediatric CPR. The program consisted of provider education, CPR ventilation tools (ventilation reminder cards, ventilation metronome), and individual CPR team member feedback. CPR events were reviewed pre- and postintervention. The first 10 minutes of each CPR event were divided into 20 second epochs, and the ventilation rate in each epoch was measured via end-tidal carbon dioxide waveform. Individual epochs were classified as within the target ventilation range (&lt;30 bpm) or clinically significant hyperventilation (≥30 bpm). The proportion of epochs with clinically significant hyperventilation, as well as median ventilation rates, were analyzed in the pre- and postintervention periods.

RESULTS
In the preintervention period (37 events, 699 epochs), 51% of CPR epochs had ventilation rates ≥30 bpm. In the postintervention period (24 events, 426 epochs), the proportion of CPR epochs with clinically significant hyperventilation decreased to 29% (P &lt; .001). Median respiratory rates decreased from 30 bpm (interquartile range 21–36) preintervention to 21 bpm (interquartile range 12–30) postintervention (P &lt; .001).

CONCLUSIONS
A quality improvement initiative grounded in improved provider education, CPR team member feedback, and tools focused on CPR ventilation rates was effective at reducing rates of clinically significant hyperventilation during pediatric CPR.

A internet afirma-se como suporte publicitário, dado que a publicidade invade o nosso quotidiano. Se os consumidores estão na internet então a publicidade acompanha-os. Contudo, a adaptação da publicidade a este meio tem de respeitar as características técnicas e de utilização. A publicidade nos media online, mais concretamente na área da imprensa, tem vindo a crescer ao longo dos últimos anos, motivando a nossa análise que terá em conta os diários generalistas: Diário de Notícias (DN), o jornal diário nacional mais antigo; o Correio da Manhã (CM) diário generalista popular de maior circulação em Portugal; e o Público, jornal diário de referência e cujo website é o mais visitado entre os órgãos de comunicação generalistas.
O nosso trabalho tem como principal objetivo evidenciar a forma como estes diários generalistas apresentam anúncios publicitários na sua homepage e aferir de que forma a estrutura e o webdesign podem limitar a aposta na publicidade digital. Para tal recorremos à análise estrutural sincrónica das homepages dos diários selecionados e à realização de três entrevistas a responsáveis dos mesmos.

En esta investigación se aplica una metodología cuantitativa fundamentada en la técnica de la encuesta que ha permitido determinar que, si bien estas empresas le dan importancia a la actividad de comunicación para establecer relaciones con sus públicos, ya sean clientes, públicos internos o cualquier otro tipo de público externo, su gestión se encuentra en un estado muy básico de desarrollo.
Intimate Partner Femicide in Portugal: The perception of intervention professionals with intimate partner violence
Authors: Neves Sofia , Correia Ariana 
Published: August 2022

This investigation paper intends to analyze perceptions and impacts from media narratives about intimate partner femicide (IPF) starting from the discourses of support/intervention professionals that work closely with intimate partner violence (IPV) victims, concretely, Criminal Police Professionals and Victim’s Support Technicians. The data collection was realized through semi structured interviews with 25 professionals in a national level, 11 females and 14 males, with an average age of 42 years (SD=7.05). The discourses emerged from the thematic analysis, underline the sensationalism proliferation that characterizes these narratives, making aware to its copycat potential in intimate partner violence perpetrators, as well as inhibits victims seeking help and skew the IPF social construction.
Based on the participants representations, media coverage for IPF recommendations were listed, highlighting the importance in defining accuracy as the foundation of media coverage. Also underscored the urge in training and specialize journalists in gender violence as well as recommended a positive approach, emphasizing cases of women who survived IPF attempts and women who overcame their victimization processes.
The representations shared by the participants converge with the national report from the Group of Experts on Action against Violence against Women and Domestic Violence that monitories the Istanbul Convention execution, pointing out the necessity in standardizing knowledge and procedures regarding to gender violence, acknowledging that media coverage varies according to beliefs, training, and personal interests of journalists (GREVIO, 2019). Therefore, it is recognized the urgency in promoting an ethically compromised journalism, adding to an effective regulation and a critical, conscient and reflexive media consumption – critical media literacy.
Teoria da Participação Pública na Internet
Authors: Gonçalves João Fernando Ferreira 
Published: August 2022

A participação pública online aparenta ser aleatória, supérflua e imprevisível, mas um olhar mais atento permite desconstruir categorias e padrões que não só explicam os novos mecanismos permitidos pela Web como apontam novas possibilidades para a participação nas organizações.
Usando o método da teoria fundamentada nos dados de Strauss e Glaser (1969), foi realizada uma análise comparativa a vários mecanismos de participação pública na internet. O estudo mostrou que a credibilidade, motivação e acesso são centrais para a morfologia e sucesso dos novos movimentos sociais e propõe uma base estruturada para a discussão das organizações sociais espontâneas virtuais.

Authors: Martins Rosana 
Published: August 2022

Hip Hop culture in São Paulo (Brazil) and Lisbon (Portugal) is characterized as a social practice that enables greater visibility and assists in identity formation amongst the younger residents of impoverished urban neighbourhoods, often young blacks. Here the hip-hop helps to generate new understandings of self, reduces social stigma and as such, provides an effective tool in the fight against racism and other forms of discrimination and exclusion.
How these individuals define and represent themselves socially? How do they define their representations and practices? What is the impact of such actions in local benefiting communities? The purpose of this work is focused how the young people in São Paulo and Lisbon appropriate of the hip-hop culture in them collective actions, which it will lead them to seek conceptual framework that could direct us to a critical reflection on issues of "belonging", "tradition", "rupture" and "continuity".

Authors: Andrade Del Cid Carmen Patricia 
Published: August 2022

Por la importancia que tiene la información con referente ambiental, este estudio se propone analizar su trayectoria en dos períodos: años 2012 y 2013, con el objetivo de analizar el espacio público de la información ambiental. El análisis de la información de los medios de comunicación sobre temas ambientales busca incidir en el pensamiento social y la reflexión crítica de acuerdo a la Agenda 21 (ONU,1992).
El soporte teórico describe el ámbito de la información emitida por los medios en dos -posibles- escenarios del espacio público: 1) como custodia ciudadana; 2) como soporte institucional del poder político.El contexto desarrolla que los más de 80 años de gobierno del Partido Revolucionario Institucional en Veracruz, ha dejado su impronta absolutista en el quehacer informativo respecto a la política, y se pregunta qué sucede en el espacio público de la información ambiental.
Los resultados comparan el comportamiento de la prensa regional sobre temas ambientales en los años 2012 y el 2103. La discusión final reflexiona sobre el importante papel que juega el periodismo en la construcción de la realidad, y en consecuencia del periodista como el primer sujeto que se involucre en los cambios profundos de estilo de vida, de organización social, de formas de pensamiento, conocimiento y principios éticos.

A peaceful pyramid? Hierarchy and anonymity in newspaper comment sections
Authors: Gonçalves João Fernando Ferreira 
Published: August 2022

Several studies have linked deindividuation to an increase in aggression and incivility. This paper seeks to ascertain the influence of anonymity and hierarchy in online aggression by comparing two different newspaper comment sections: one with a hierarchical system and the other with an equalitarian setting. This study distinguishes itself form previous works by analyzing systems where identification is optional and where identified and anonymous users coexist.
The hierarchical solution might be relevant to dissuade aggression when optional identifiability is seen as an essential asset. Results show that a hierarchical system provides some improvements in terms of civility and comment moderation, but that poor implementation of the hierarchy causes perversions in the system and affects its effectiveness.

TOTAL DİZ ARTROPLASTİSİ SONRASI KLİNİK SONUÇLAR VE HASTA MEMNUNİYETİ: KİMLER DAHA MEMNUN?
Authors: KORKMAZ İzzet , KORKMAZ Nurdan 
Published: August 2022

AMAÇ: Primer diz osteoartriti nedeni ile total diz artroplastisi (TDA) uygulanan hastaların ağrı, fonksiyonel durum ve memnuniyet düzeylerini değerlendirmek ve memnuniyet düzeyi ile demografik ve klinik özellikler arasındaki ilişkiyi incelemek amaçlanmıştır.
GEREÇ VE YÖNTEM: Evre III veya IV primer diz osteoartriti nedeniyle TDA uygulanmış, operasyon üzerinden bir yıl geçmiş ve yeterli takibi olan 44 hastanın kayıtları retrospektif olarak tarandı. Demografik ve klinik özellikleri kaydedildi. Operasyon öncesi ve operasyon sonrası birinci yılda Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) ağrı şiddeti ve fonksiyonu değerlendirmek için kullanıldı. Hastaların operasyon sonrası birinci yıldaki memnuniyet düzeyi 5 puanlık bir likert skala ile değerlendirildi.
BULGULAR: Tüm WOMAC skorları (WOMAC-ağrı, WOMAC-tutukluk, WOMAC-fonksiyon ve WOMAC-total) cerrahi sonrası birinci yılda cerrahi öncesine kıyasla istatistiksel anlamlı olarak düşüş gösterdi. TDA sonrası birinci yılda çok memnun ve memnun olan hastaların oranı %93,2 idi. Memnuniyet düzeyi, tüm WOMAC skorları ile istatistiksel olarak anlamlı negatif ilişki gösterdi.

Ameliyat Öncesi Perforatör Tayininde Dinamik İnfrared Termografi ve El Doplerinin Başarısının Karşılaştırılması
Authors: SERT Gökhan 
Published: August 2022

Amaç: Termografik görüntüleme, perforatör flep cerrahisinde ameliyat öncesi perforatör tayini için kullanılan farklı yöntemler arasında güncel bir seçenek olarak öne çıkmaktadır. Bu amaçla en sık kullanılan yöntem ise el dopleri ile muayenedir. Çalışmada farklı etiyolojiler sonucunda ortaya çıkan defektlerin onarımında kullanılan perforatör fleplerin perforatör tayininde, dinamik infrared termografi (DIRT) ve el dopleri ile muayene tekniklerinin başarılarının karşılaştırılması amaçlanmıştır.
Gereç ve Yöntem: Kliniğimizde Mayıs 2021 – Aralık 2021 tarihleri arasında perforatör flep cerrahisi gerçekleştirilen hastalara ait kayıtlar retrospektif olarak incelendi. Tüm hastaların el dopleri ve termal görüntüleme ile yapılan işaretlemeleri ve ameliyat içi bulguları değerlendirildi.
Bulgular: Toplam 11 hastanın %54,5‘inde etiyoloji travma, %36,3‘ünde tümör rezeksiyonu ve %9,2‘sinde yanıktı. Rekonstrüksiyon amacıyla iki hastada medial sural arter perforatör flebi, dört hastada anterolateral uyluk flebi, iki hastada süperfisiyel radial arter perforatör flebi, bir hastada hipotenar serbest flep, bir hastada anterior tibial arter perforatör flebi ve bir hastada derin inferior epigastrik arter perforatör flebi kullanıldı. Ameliyat öncesinde el dopleri ile 11 perforatör sinyali tespit edildi, DIRT ile 19 perforatör lokalize edildi ve ameliyat sırasında toplam 20 perforatör ile karşılaşıldı. Bu perforatörlerin %55’i el dopleri ile işaretlenen perforatörler iken, %95’i DIRT ile tespit edilen perforatörlerdi. İki yöntemin ameliyat öncesi perforatör lokalize etmedeki başarıları arasındaki fark istatistiksel olarak anlamlı bulundu (p=0.005). Komplikasyon olarak hastaların yalnızca birinde ameliyat sonrası üçüncü günde gelişen kompresyon sebepli venöz tromboz ile karşılaşıldı.
Tartışma: Perforatör flep cerrahisinde başarı için en önemli basamaklardan biri perforatörün lokalizasyonunun ameliyat öncesinde doğru şekilde tespit edilebilmesidir. Bu amaçla kullanılan yöntemler içerisinde termografi güncel ve güvenilir bir yöntem olarak öne çıkmaktadır. Dinamik görüntüleme kullanılarak değerlendirmede başarı artırılabilir. El dopleri ile karşılaşılan yanlış pozitiflikler nedeniyle yerine termografi tercih edilebilir.
Sonuç: Perforatör flep cerrahisinde ameliyat öncesi perforatör seçiminde dinamik infrared termografiye izin veren akıllı telefon uyumlu termal kameraların kullanılması, el dopleri ile yapılan değerlendirmelerden daha başarılı sonuç vermektedir.
Software-based simulation to analyze the variation of digital modulation and atmospheric condition on the free space optic (FSO) link performance
Authors: Khair Fauza , Zulherman Dodi , Auliana Rifani 
Published: August 2022

Free Space Optic (FSO) is the solution for telecommunications technology that offers high data rates, wide bandwidth, and low power consumption. However, to maximize the performance of the FSO system, the modulation used should be considered in environmental conditions. This study aims to compare the performance of the FSO communication link based on digital modulation variations used in various weather conditions, including sunny, rainy, and foggy weather. This study uses two attenuation models, namely the Kim and Kruse models, with variations in transmission distance from 500 meters to 10 kilometers. Modulation variations used include QPSK, 8-PSK, 16-PSK, and 16-QAM at 10 Gbps bitrate. The simulation is accomplished using OptiSystem 17.0 software. The study results show that sunny weather (very clear) has the best visibility compared to rain and fog conditions with an attenuation value of 0.46 dB/km on the Kim and Kruse models. QPSK modulation has the best performance with a BER value of less than 1x10-12 up to a transmission distance of 8 km in sunny weather, 3 km in rainy weather (medium rain), and 800 m in foggy (moderate fog) weather. The 8-PSK modulation has a BER value of less than 1x10-12 with a range of 2000 m in sunny weather and 1500 m in rainy weather but does not meet the standards in foggy weather conditions. 16-PSK and 16-QAM modulation have above baseline BER values ​​during rainy and foggy conditions, but 16-QAM modulation still has a BER value of less than 1x10-3 during foggy conditions at a distance of 500 m.
