Quando o mundo do trabalho levanta voo? Altos e baixos dos tripulantes de cabine
Authors: Della Santa Roberto 
Published: September 2023

Neste ensaio defendemos que o modo de operar para o bem-estar social, a saúde de nexo psicofísico, a segurança e a proteção de passageiros e tripulantes de voo civil é o cerne do trabalho do pessoal de voo e cabine, uma categoria socioprofissional essencial. Este é o trabalho realmente existente da categoria de tripulantes de cabine e o que distingue o saber-fazer do pessoal de voo. Ainda que sua figuração pública – dos mitos fundacionais às imagens-fetiche – transite entre as figuras do prestador de serviços de bordo ou de uma etiqueta envolta em “charme”, tal ideário e imaginário, socialmente construídos, não resistem a uma análise e caracterização algo mais detida. As situações de risco, de periculosidade ou de emergência, bem como a definição, hierarquização e implementação de medidas adequadas a cada caso, fazem parte do núcleo desta atividade vital. Estas reflexões críticas foram elaboradas a partir de uma pesquisa-ação junto ao Inquérito às Condições de Vida e Trabalho do Pessoal de Voo e Cabine.[1] Palavras-Chave: estudos globais do trabalho; pessoal de voo; restruturação produtiva; trabalho emocional; sentido do trabalho.[1] Atalho para os projetos do Observatório para as condições de trabalho e vida.

Knowledge Utilisation Analysis: measuring the utilisation of knowledge sources in policy decisions
Authors: Jørgensen Jonas Videbæk 
Published: September 2023

Background:
Understanding knowledge utilisation in policymaking is a core task for the social and political sciences. However, limitations and biases abound in commonplace approaches to measuring such use. Consequently, we have little systematic evidence of the extent to which knowledge sources are used in policy decisions.
Aims and objectives:
This article discusses existing approaches to studying knowledge utilisation and introduces the analytical approach, Knowledge Utilisation Analysis (KUA), which harnesses the growing quantities of documents available online.
Methods:
KUA offers a four-step procedure that enables researchers to systematically compare policy documents with knowledge sources and measure the degree to which policy decisions follow or contradict relevant knowledge.
Findings:
The article showcases KUA in a study of Danish primary education and active labour market policies from 2016 to 2021. By analysing 1,159 documents, KUA is leveraged to study levels of knowledge utilisation across policy areas, research methods, and provider types.
Discussion and conclusion:
KUA contributes methodological innovation to measuring knowledge utilisation by systematically matching knowledge sources with policy decisions. KUA can, thereby, enhance empirical research on the relationship between knowledge and policy.

We present the network architecture of Alibaba Cloud DCs and investigate their traffic characteristics based on statistical data and captured traces. The statistical coarse-grained data are in the granularity of one minute, while the captured traces are fine-grained data that are in the granularity of one packet. We study the traffic features from the perspective of a macroscopic view, network performance, and microscopic view. The results report that the average utilization ratio of spine switches is stable when the observation time period reaches one day and the intra-ToR traffic ratio is in the range of 2%–10%. By mapping the folded-Clos topology to a tree topology and considering logical switching planes, we obtain the traffic matrix among pods from the average port utilization ratio. As we further investigate the perspective of network performance and the microscopic view, we find that there is no cell loss happening as the normalized queue speedQsis lower than 0.4. The normalized queue speedQsis defined as the total bytes of a queue sent in 1 s divided by 100 Gb, which reflects the packet sending speed of the queue. The observed maximum buffer size for one port conforms with the calculated maximum buffer occupation of 2.8 MB. By analyzing the captured traces, we find that the packet length is subject to a trimodal distribution. Under a time granularity of 10 ms, the instant bandwidth of one ToR port could reach 96 Gb/s at an average load of around 0.2 under a maximum link bandwidth of 100 Gb/s.
ZR 400  Gbit/s and 800  Gbit/s use cases, trials, deployments, and future prospects [Invited]

Published: September 2023

As bandwidth grows operators are moving from 100 Gbit/s to 400 Gbit/s ports on core routers with wavelengths on underlying transmission also increasing to 400 Gbit/s and higher. Developments in pluggable coherent optical transceivers such as ZR optics present different optical layer architectures: pluggable coherent transceivers inserted into the router versus external transponders and “hop-by-hop” architectures, in which packets pass through multiple intermediate routers, versus “optical express” architectures via ROADMs. The paper describes using a bespoke modeling tool to compare cost and power consumption for various 400 Gbit/s architectures, applied to the core network of a major operator as total bandwidth increases from current levels ∼28Tbit/s to a future 220 Tbit/s scenario. The model shows that, as bandwidths increase, “optical express” architectures become lower cost compared to “hop-by-hop” architectures. The paper describes a field trial of pluggable 400 Gbit/s ZR+ transceivers directly deployed in routers and transported over a ROADM network and reviews architectural options likely to arise as bandwidths increase to 800 Gbit/s. For 400 Gbit/s and higher, operators face a range of optical layer architectures: the best outcome gives the lowest cost and power consumption while enabling efficient network operations, and it could be that different solutions are best for different networks.

Health-related quality of life in patients accessing medicinal cannabis in Australia: The QUEST initiative results of a 3-month follow-up observational study
Authors: Tait Margaret-Ann , Costa Daniel S.J. , Campbell Rachel , Norman Richard , Warne Leon N. , Schug Stephan , Rutherford Claudia 
Published: September 2023

Aims
Patients with chronic health conditions not responding to conventional treatment can access medicinal cannabis (MC) prescriptions from clinicians in Australia. We aimed to assess overall health-related quality of life (HRQL), pain, fatigue, sleep, anxiety, and depression in a large real-world sample of patients accessing prescribed medicinal cannabis. We hypothesized that all patient-reported outcomes (PROs) would improve from baseline to 3-months.

Methods
The QUEST Initiative is a large prospective multicenter study of patients with any chronic health condition newly prescribed medicinal cannabis between November 2020 and December 2021. Eligible patients were identified by 120 clinicians at medical centers across six Australian states. Consenting participants completed the EuroQol Group EQ-5D-5L health status questionnaire; European Organization for Research & Treatment of Cancer Quality of Life questionnaire (QLQ-C30); Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms in Fatigue and Sleep Disturbance, and the Depression Anxiety Stress Scale (DASS-21) before starting therapy, at 2-weeks titration, then monthly for 3-months.

Results
Of the 2762 consenting participants, 2327 completed baseline and at least one follow-up questionnaire. Ages ranged between 18–97 years (mean 51y; SD = 15.4), 62.8% were female. The most commonly treated conditions were chronic pain (n = 1598/2327; 68.7%), insomnia (n = 534/2327; 22.9%), generalized anxiety (n = 508/2327; 21.5%), and mixed anxiety and depression (n = 259/2327; 11%). Across the whole cohort both EQ-5D-5L utility scores and QLQ-C30 summary scores showed clinically meaningful improvement in HRQL from baseline to mean follow-up with d = 0.54 (95%CI:0.47 to 0.59) and d = 0.64 (95%CI:0.58 to 0.70) respectively; and clinically meaningful improvement in fatigue (d = 0.54; 95%CI:0.48 to 0.59). There was clinically meaningful reduction of pain for those with chronic pain (d = 0.65; 95%CI:0.57 to 0.72); significant improvements for those with moderate to extremely severe anxiety (X2 = 383; df = 4; p<0.001) and depression (X2 = 395; df = 4; p<0.001); and no changes in sleep disturbance.

Conclusions
We observed statistically significant, clinically meaningful improvements in overall HRQL and fatigue over the first 3-months in patients with chronic health conditions accessing prescribed medical cannabis. Anxiety, depression, and pain also improved over time, particularly for those with corresponding health conditions. The study continues to follow-up patients until 12-months to determine whether improvements in PROs are maintained long-term.

A scoping review protocol of the lived experiences of doing a PhD in Africa
Authors: Omoya Oluwatomilayo , Jacob Udeme Samuel , Odeyemi Olumide A. , Odeyemi Omowale A. 
Published: September 2023

Objective
This scoping review aims to investigate the available literature on the lived experiences of doing a PhD in African Universities.

Introduction
The continent of Africa still contributes a minimal amount of research towards global research outputs. The need for increased research capacity and outputs have been identified as priority for growth and development. There is a substantial need for evidence-based solutions that can alleviate some of these complexities. For example, challenges still exist in the disease burden faced, economic poverty and lack of infrastructure in various contexts.

Methods and analysis
Multiple databases will be searched, including the EBSCO Host, Scopus, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline (Ovid), and Google Scholar. The scoping review will be conducted using the Arksey & O’Malley (2005)’s six-step approach in conjunction with the Joanna Briggs Institute (JBI) methodology for scoping reviews. Studies that examined the perspective of PhD (Doctor of Philosophy) candidates, supervisors from Africa, and research studies focusing on the common barriers and facilitators concerning research in Africa will be included. Studies that explore the perspectives of other postgraduate cohorts will be excluded.

Ethics and dissemination
Ethics application will not be required but findings will be disseminated through publications, conference presentation, policy, and relevant stakeholders.

Review registration number
This study has been registered with the Open Science Forum (OSF).
Characterization of combined endoscopies and aerodigestive care: An analysis of utilization and financial feasibility
Authors: Brinkmeier Jennifer , Al-Hammadi Noor , Shashidhar Sumana , Hinyard Leslie , Patel Dhiren 
Published: September 2023

Background
Aerodigestive care is one model of multi-disciplinary care, which is a valuable tool for both providers and patients. Aerodigestive care models are associated with improved outcomes, reduced anesthesia exposure, reduction in hospital admissions, and fewer days of missed work or school. This is the first study to explore national usage and cost trends in combined endoscopy utilization to identify gaps in care and the potential for financial resource optimization.

Methods
Data from the Healthcare Cost and Utilization Project (HCUP) Kid’s Inpatient Sample (KID) was used from 2016 and 2019. Diagnoses and procedures were identified using ICD-10 codes, for patients with hospital length of stay less than 1 day. Demographic data were identified, and survey-weighted means and proportions were computed. Bivariate comparisons were made using Rao Scott Chi-Square tests. National estimates of charges were computed with discharge weights, developed using the American Hospital Association (AHA) universe.

Key results
White, high-income patients, and those at urban teaching hospitals received the greatest proportion of combined endoscopic procedures. The cost/charges associated with combined endoscopies are less than for separate gastrointestinal (GI) or airway only endoscopies combined. However, combined procedures comprise a smaller share of national aggregate cost.

Conclusions
National utilization trends highlight racial and socioeconomic disparities and suggest differences in access based on hospital characteristics, despite the reduced cost/charges of the combined procedure. For patients with a need for combined aerodigestive procedures, there appears to be a cost-savings opportunity to increase efforts for combined procedures at the level of the clinician or hospital.

Authors: Rezki Deska Andina , Firmansyah Isra , Darussalam Dora , Yusuf Sulaiman , Sovira Nora , Bakhtiar Bakhtiar 
Published: September 2023

Background Hyperbilirubinemia occurs in 60% of full term and 80% of premature infants. Phototherapy is the main treatment, but it has side effects, sometimes requires hospitalization, and causes the baby to be separated from the mother. Underdeveloped gut microflora and increased enterohepatic circulation in newborns contribute to increased serum bilirubin levels in early life.
Objective To assess the efficacy of adding probiotic L. reuteri on phototherapy in full-term neonates with hyperbilirubinemia.
Methods In this double-blind, randomized clinical trial, full term infants with hyperbilirubinemia at Dr. Zainoel Abidin Hospital, Banda Aceh, Aceh, Indonesia, were randomly assigned to either an intervention or control group. All subjects received phototherapy. The intervention group was also given five drops of L. reuteri once a day orally before phototherapy started, while the control group received a placebo. Bilirubin levels after 24-hour phototherapy were evaluated in both groups.
Results A total of 42 term neonates met the inclusion criteria. The intervention group had a significantly greater decrease in total serum bilirubin (TSB) level (6,517 mg/dL) than did the control group (4,434 mg/dL) (P<0.001), as well in indirect bilirubin levels in the intervention group had decrease 6.40 mg/dL while in the control group 4.43 mg/dL after 24 hours of phototherapy (P<0.001).
Conclusion In full-term neonates with hyperbilirubinemia who underwent 24-hour phototherapy, adding probiotic L. reuteri leads to a significantly greater reduction in total and indirect bilirubin levels compared to the control group.

Published: September 2023

Background The global burden of childhood cancer is poorly quantified, but it is estimated that 80% of all children with cancer live in low- and middle-income countries with cure rates of childhood cancer far lower than in high-income nations.
Objective To describe the Yogyakarta Region pediatric cancer profile from 2010-2019 and compare it to that of a 2000-2009 study in the same setting.
Methods This retrospective study of childhood cancer was conducted in patients aged £18 years and diagnosed in Dr. Sardjito General Hospital from 2010 to 2019. Pediatric cancer patient data were collected from hospital hardcopy and electronic medical records. An estimated annual average incidence rate of childhood cancer was calculated and the number of patients by their regions of origin were visualized. The number of childhood malignancies recorded is also compared by the number found in 2000-2009 study.
Results There were 1,839 new cases registered in Yogyakarta Pediatric Cancer Registry during the study period. The mean age at diagnosis was 6.3 years and male-to-female ratio was 1.4: 1.0. Fifty-six% of cancers were diagnosed in the 0-5-years age group. The most common diagnosis category was leukemia, which accounted for 60% of all childhood malignancies. The three most common diagnoses were acute lymphoblastic leukemia (44%), acute myeloid leukemia (12%), and retinoblastoma (7%). The annual average incidence rates of leukemia and solid tumors were 26.8 and 17.5 per million, respectively. The number of patients registered in 2000-2009 study was 1,124 case. Therefore, there was an increase of 63.6% in the number of childhood malignancies registered in 2010-2019 compared to the 2000-2009 study.
Conclusion There is an increase in the number of childhood malignancies registered in 2010-2019 compared to the 2000-2009 study. The number of patients referred to our hospital increased, indicating a more inclusive registry, better referral system, and better access to health care facility.

Authors: Rahmawati Dr 
Published: September 2023

Background : Prevalence of congenital heart disease is approximately 8/1000 live births and majority of them are diagnosed during evaluation of a murmur detected either during a routine follow-up or while assessment during an intercurrent illness. NADAS criteria can be used as screening test with hight a sensitivity and specificity regarding ability to differentiate pathologic from innocent murmurs.
Aim : The aim of the study was to assess the accuracy of the NADAS criteria in helping to diagnose disease in children suspected of having congenital heart disease.
Methods : This was a diagnostic study with a cross-sectional approach and Inclusion criteria were children aged 1 month - 12 years from history and physical examination found a history of recurrent ARI, poor nutritional status, failure to thrive, found cardiac murmurs, without/any cyanosis who attended the outpatient cardiology pediatric at Haji Adam Malik General Hospital between Januari - july 2021. Data Analysis was created using the program IBM SPSS Statistics version 25
Results : 70 children were screened. 60 children were detected to have CHD. 63,3% of the study population in the age group <5 year had a heart disease. All CHD patients had poor nutritional status, abnormal ECG and 88.33% had a history of recurrent ARI, 80% had abnormal chest x-ray, and 55% had abnormal S2. A grade 3 or higher systolic murmur was found in 78.33% of patients had CHD.
Conclusion : NADAS criteria can be used as a screening test for helping to diagnose disease in children suspected of having CHD with accuracy 87.14%, sensitivity of 88.33%, specificity was 80% when score at 3 (1 major + 2 minor) and AUC value is 0.842.

Published: September 2023

Active compounds found in Syzygium myrtifolium Walp. leaves such as flavonoids, phenolics, and betulinic acid are known to have pharmacological activities. This research aimed to find active compounds found in Syzygium myrtifolium Walp. leaves, which have anticancer activity by inhibiting the protein leukotriene A4 hydrolase. Molecular docking methods are used to predict the activity and affinity between ligand-proteins. The research was conducted in silico on the active compound in Syzygium myrtifolium Walp. leaves, which met the five criteria of Lipinski’s rule for leukotriene A4 hydrolase with PDB code 3U9W. The software used were YASARA, MarvinSketch, and PLANTS, which can optimize ligands and bind ligand molecules to receptors. Then it was visualized using Discovery Studio Visualizer and analyzed the prediction of pharmacokinetics and toxicity. Docking results show that the four active compounds from the leaves of Syzygium myrtifolium Walp., namely bis (2-ethylhexyl) hexanedioate, 3-octadecyne, 1- octadecene, and (2E,6E)-farnesol have a lower docking score compared to bestatin; therefore, these four compounds have the potential to inhibit leukotriene A4 hydrolase receptors and can be candidates for colorectal anticancer compounds.
Early epigraphic evidence for Germanic weak class-III verbs
Authors: Mees Bernard 
Published: September 2023

AbstractThe namesLubainisandVanaeniarecorded in inscriptions from Namur have long been proposed to preserve evidence that supports the reconstruction of the stem of the Germanic weak class-III verbs as originally featuring a diphthong *-ai-. Cognates of the Gothic weak class-III verbweihan›to consecrate‹ have similarly been widely held to be preserved in two inscriptions rescued over a century ago from the Danish votive bogs. The attested formswijuandwijasuggest the development of a first-person singular present indicative ending -jǣ, much as would be expected of a weak class-III verb in Northwest Germanic. Gothicweihan›to consecrate‹ is a factitive, however, andwijuandwijaappear to have developed in a manner contrary to that assumed in recent accounts of the morphological origin of the weak class-III verbs.
Species diversity of the brown alga Lobophora (Dictyotales) in the Con Co Island Marine Protected Area, Vietnam

Published: September 2023

Abstract
We reevaluated species diversity of the brown alga Lobophora in Vietnam’s Con Co Marine Protected Area (MPA), where only one species had previously been reported. Integrating morphological, ecological, and molecular analyses, we redefined the genus diversity, identifying nine species including two new ones: L. asiatica, L. boussoleae, L. lamourouxii, L. obscura1, L. pachyventera3, L. thailandensis, L. quangtriensis sp. nov., L. vietnamensis sp. nov., and Lobophora sp.1VNA. Lobophora variegata, the sole species previously reported, was absent. This study expands the number of Vietnam’s documented Lobophora species to 11. This work reevaluated Lobophora diversity in Vietnam based on a small island, contributing valuable seaweed diversity reference data for Con Co MPA management. Notably, within the MPA, Lobophora species exhibited no coral-aggressiveness, potentially serving as a health indicator for coral reef communities.
