AbstractAdverse birth outcomes are a common cause of health problems in developing nations and have a significant negative impact on infant health as well as financial costs to families, communities, and the world. Mothers with HIV may be at increased risk of adverse birth outcomes. However, there is a limited study about adverse birth outcomes among mothers with HIV around the world including in Ethiopia. Therefore this study aimed to assess adverse birth outcomes and associated factors among mothers with HIV Facility based cross-sectional study was conducted among mothers with HIV who gave birth in northwest Amhara region referral hospitals from September 2016 to September 2019. Simple random sampling was used to select 590 mothers. Bivariable and multivariable logistic regressions were carried out to identify factors. Statistical significance was declared by using a p-value < 0.05. An adjusted odds ratio was used to show the magnitude of the association. Out of a total of 590 mothers, the prevalence of adverse birth outcomes among HIV-positive mothers was 21% (95% CI 17.8–24.6%). History of spontaneous abortion [AOR = 1.9, 95% CI (1.19, 3.70)], PROM [AOR = 3.55, 95% CI (1.72, 7.30)], opportunistic infection [AOR = 3.38, 95% CI (1.50, 8.22)], pre-pregnancy BMI of < 18.5 [AOR = 5.61, 95% CI (1.97, 15.91)], MUAC < 23 cm [AOR = 2.56, 95% CI (1.10, 5.97)], and ANC visit of < 4 times [AOR = 3.85, 95% CI (2.34, 6.55)] were significantly associated with Adverse birth outcome. The prevalence of adverse birth outcomes was high. Abortion history, MUAC, BMI, Opportunistic infection, PROM, and a number of ANC visits were associated with adverse birth outcomes. This study suggests to increase number of antenatal care follow-ups, prevent and treat opportunistic infections, and focus on early detection and treatment of pregnancy-related complication

Published: December 2022

AbstractNonlinear distortion (noise) limits many communication systems, demanding a means of estimating system performance via device nonlinear characteristics. The noise power ratio (NPR) method which was proposed in 1971 solves this problem for systems with Gaussian stimuli or with special nonlinearity, but practical and accurate methods for many communication systems with non-Gaussian stimuli are rare. Here we propose a probability-maintained (PM) NPR method to accurately measure the spectrum of nonlinear noise via a spectrum analyzer in non-specific systems, including systems with non-Gaussian stimuli. Using an equivalent additive noise model in which the spectrum of equivalent nonlinear noise is the measurement result of PM NPRs, nonlinear system performance could be estimated with an error of 0.5 dB. Further, we find that zero-mean Chi-square noise, instead of Gaussian noise, should be selected for large memory and low-order nonlinear systems. Our method is verified in seven different scenarios with various nonlinear mechanisms and communication applications.

Authors: Stone Michael A. , Lough Melanie , Kühnel Volker , Biggins Anna E. , Whiston Helen , Dillon Harvey 
Published: December 2022

Purpose:
Perceived sound quality was variously compared between either no aiding or aiding with three models of hearing aid that varied the microphone position around the pinna, depth of the receiver in the auditory meatus, degree of meatal occlusion, and processing sophistication. The hearing aids were modern designs and commercially available at the time of testing.

Method:
Binaural recordings of multichannel spatially separated speech and music excerpts were made in a manikin, either open ear or aided. Recordings were presented offline over wide-bandwidth, high-quality insert earphones. Participants listened to pairs of the recordings and made preference ratings both by clarity and externality (a proxy for “spaciousness”). Two separate groups of adults were tested, 20 with audiometrically normal hearing (NH) and 20 with mild-to-moderate sensorineural hearing loss (hearing impaired [HI]).

Results:
For ratings of speech clarity, the NH group expressed no preference between the open ear and a deeply inserted occluding aid, both of which were preferred to a low-pass filtered output of the same aid. For the music signal, a small preference emerged for the open-ear recording over that of the aid. For the HI group, clarity of the deeply inserted aid was similar to in-the-ear and behind-the-ear devices for speech, but worse for music. Ratings of spaciousness produced no clear result in either group, which can be attributed to study limitations and/or participant factors.

Conclusion:
Based on clarity, a wide bandwidth, particularly to beyond 5 kHz generally and below 300 Hz for music, is desirable, independent of hearing aid design.

Published: December 2022

Purpose:
Using virtual reality (VR) to support rehabilitation is an emerging area of research that may offer people with communication disorders a stable and safe communication environment to practice their communication skills. There are currently no VR applications that have been designed to assess or treat cognitive-communication disorders (CCDs) following traumatic brain injury (TBI). Therefore, this study aimed to explore the views of speech-language pathologists (SLPs) who work with people who have a TBI to generate ideas and considerations for using VR in rehabilitation for CCDs. VR researchers were included to provide expert advice about VR technology.

Method:
A total of 14 SLPs and three VR specialists participated in an online interview or focus group. Semistructured discussions explored participants' perspectives related to potential ideas for VR use and any perceived barriers and facilitators to VR implementation for managing CCDs following TBI. Data were video- and audio-recorded, transcribed, and analyzed qualitatively using thematic analysis.

Results:
Three main themes were generated from thematic analysis: VR is a tool that could enhance clinical practice, the need to consider and navigate potential red flags, and solutions to pave the way forward. Suggestions to overcome perceived barriers to VR use were also provided.

Discussion:
Participants expressed interest in using VR for rehabilitation of CCDs following TBI. However, potential barriers and risks to use should be considered prior to implementation. The findings offer guidance to support future research and development of VR in this field.

Published: December 2022

AbstractSpectrum resources are becoming harder to come by for wireless communications. The spectrum environment map (SEM), which depicts the electromagnetic environment's current state and future trend, is a valuable technique for managing and allocating spectrum resources. Most SEM construction approaches only take static SEMs into account and cannot forecast time‐domain changes and trends of SEMs in dynamic scenes. In this paper, a brand‐new temporal SEM prediction method for the high dynamic spectrum environment is proposed. This method is based on knowledge of radiation source and the optical flow driven by propagation channel models. First, a novel radiation source localization strategy is designed to obtain the radiation source movement information. Then, the optical flow field of the available SEMs is combined with the information regarding radiation source movement. In order to forecast future SEMs, a propagation model driven reconstruction technique is developed. Simulation findings demonstrate how well the suggested strategy is tailored to capture the spatiotemporal correlation of SEMs. This technique performs better than the state‐of‐the‐art in terms of single‐ and multiple‐step SEM predictions.
Dysphagie bei tracheotomierten Patienten nach Langzeitbeatmung
Authors: Heidler M.-D. 
Published: December 2022

ZusammenfassungUnabhängig von der Art der kritischen Erkrankung haben tracheotomierte Patienten ein hohes Risiko für die Entwicklung einer Schluckstörung. Diese ist potenziell lebensbedrohlich, da sie zu Aspiration und Pneumonie führen kann. Vor einer oralen Nahrungsgabe sollte daher unbedingt eine Schluckdiagnostik mittels Bolusfärbetest und/oder FEES durchgeführt werden. Da ein physiologischer Luftstrom durch den Larynx und ein adäquater subglottischer Druck Schlüsselkomponenten eines effektiven Schluckaktes sind, sollte eine Oralisierung bei geblockter Trachealkanüle möglichst vermieden werden.

Abstract
Objective To develop and validate a protocol for the use of the Dietary Guidelines for the Brazilian Population (DGBP) in the individual dietary advice for pregnant women assisted in primary healthcare (PHC).
Methods Methodological study that involved the elaboration of a protocol in six steps: definition of the format, definition of the instrument to evaluate food consumption, systematization of evidence on food and nutrition needs of pregnant women, extraction of DGBP recommendations, development of messages of dietary guidelines and content, and face validity. The analyses of the validation steps were carried out by calculating the Content Validity Index (CVI) and thematic content analysis.
Results As products of the steps, the protocol structure was defined and the dietary advice for pregnant women were elaborated, considering physiological changes, food consumption, nutritional and health needs, and socioeconomic conditions of this population. The protocol was well evaluated by experts and health professionals in terms of clarity, relevance (CVI > 0.8), and applicability. In addition, the participants made some suggestions to improve the clarity of the messages and to expand the applicability of the instrument with Brazilian pregnant women.
Conclusion The instrument developed fills a gap in clinical protocols on dietary advice for pregnant women focused on promoting a healthy diet, contributing to a healthy pregnancy. In addition, it demonstrates potential to contribute to the qualification of PHC professionals and to the implementation of the DGBP recommendations.

Abstract
Objective Cervical pregnancy is challenging for the medical community, as it is potentially fatal. The treatment can be medical or surgical; however, there are no protocols that establish the best option for each case. The objective of the present study was to describe the cases of cervical pregnancy admitted to a tertiary university hospital over a period of 18 years.
Methods A retrospective study based on a review of the medical records of all cervical pregnancies admitted to the Women's Hospital at Universidade Estadual de Campinas, Southeastern Brazil, from 2000 to 2018.
Results We identified 13 cases of cervical pregnancy out of a total of 673 ectopic pregnancies; only 1 case was initially treated with surgery because of hemodynamic instability. Of the 12 cases treated conservatively, 7 were treated with single-dose intramuscular methotrexate, 1, with intravenous and intramuscular methotrexate, 1, with intravenous methotrexate, 1, with 2 doses of intramuscular methotrexate, and 2, with intra-amniotic methotrexate. Of these cases, one had a therapeutic failure that required a hysterectomy. Two women received blood transfusions. Four women required cervical tamponade with a Foley catheter balloon for hemostasis. There was no fatal outcome.
Conclusion Cervical pregnancy is a rare and challenging condition from diagnosis to treatment. Conservative treatment was the primary method of therapy used, with satisfactory results. In cases of increased bleeding, cervical curettage was the initial treatment, and it was associated with the use of a cervical balloon for hemostasis.

Published: December 2022

Abstract
Background In the Philippines, the exact prevalence of Parkinson's disease (PD) has not yet been determined. Although cases can be extrapolated from medical registries, this method may undermine actual case rates. A reliable screening tool for PD is essential for a timely diagnosis and community-based epidemiological studies. The most widely used screening questionnaire for PD diagnosis was developed by Tanner et al., which consists of nine questions about the motor symptoms of PD. Although this questionnaire has been translated to several languages, the translated version must be validated for use in our local setting.
Objective To determine the validity of the Cebuano version of a PD screening questionnaire.
Method The questionnaire was translated from English to Cebuano by a hired language specialist. Each item was supplied with a yes, no, or don't know answer. A total of 73 patients with PD and 244 control subjects completed the study.
Results The overall Cronbach alpha for internal consistency of the questionnaire was 0.9410. The item on tremor had the highest sensitivity (97.26%), while the item on problems with buttoning had the highest specificity (100.00%). A cut-off score  ≥ 3 obtained the best Youden index (99.18%), with a sensitivity of 100.00% and a specificity of 99.18%. The questionnaire had an almost perfect predictive ability to diagnose PD (AUC of 0.9994).
Conclusion The translated version of the Tanner questionnaire is a validated instrument to identify PD in a literate Cebuano population.

Abstract
Objective To describe the clinical results of patients admitted and managed as cases of placenta accreta spectrum (PAS) at a Central American public hospital and the influence of the prenatal diagnosis on the condition.
Materials and Methods A retrospective analysis of PAS patients treated at Hospital Bertha Calderón Roque, in Managua, Nicaragua, between June 2017 and September 2021. The diagnostic criteria used were those of the International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, in French). The population was divided into patients with a prenatal ultrasonographic diagnosis of PAS (group 1) and those whose the diagnosis of PAS was established at the time of the caesarean section (group 2).
Results: During the search, we found 103 cases with a histological and/or clinical diagnosis of PAS; groups 1 and 2 were composed of 51 and 52 patients respectively. Regarding the clinical results of both groups, the patients in group 1 presented a lower frequency of transfusions (56.9% versus 96.1% in group 2), use of a lower number of red blood cell units (RBCUs) among those undergoing transfusions (median: 1; interquartile range: [IQR]: 0–4 versus median: 3; [IQR]: 2–4] in group 2), and lower frequency of 4 or more RBCU transfusions (29.4% versus 46.1% in group 2). Group 1 also exhibited a non-significant trend toward a lower volume of blood loss (1,000 mL [IQR]: 750–2,000 mL versus 1,500 mL [IQR]: 1,200–1,800 mL in group 2), and lower requirement of pelvic packing (1.9% versus 7.7% in group 2).
Conclusion Establishing a prenatal diagnosis of PAS is related to a lower frequency of transfusions. We observed a high frequency of prenatal diagnostic failures of PAS. It is a priority to improve prenatal detection of this disease.

Published: December 2022

Abstract
Background In recent years, cyclooxygenase-2 (COX-2) has been identified as a cancer stem cell (CSC) marker in gliomas. Nevertheless, the clinical and prognostic significance of COX-2 in glioma patients remains controversial.
Objective To evaluate the correlation of COX-2 with the prognosis in glioma patients.
Methods Eligible studies on this subject were included, and pooled odd ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (95%CIs) were estimated. Publication bias was assessed through funnel plots, and heterogeneity and sensitivity were analyzed as well.
Results In the present study, 11 articles with a total of 641 patients were included. The high expression of COX-2 in glioma patients was negatively associated with overall survival (OS) (n = 11; HR = 2.26; 95%CI = 1.79–2.86), and the subgroup analysis showed no differences in OS between Asian (n = 5; HR = 2.16; 95%CI = 1.57–2.97) and non-Asian (n = 6; HR = 2.39; 95%CI = 1.69–3.38) glioma patients. The Begg funnel plots test indicated that there was no evident risk of publication bias in the meta-analysis.
Conclusion The present study suggests that COX-2 could be recommended as a useful pathological and prognostic biomarker in the clinical practice.
Cooperative dynamics in two-component out-of-equilibrium systems: molecular ‘spinning tops’
Authors: Dotsenko Victor S , Viot Pascal , Imparato Alberto , Oshanin Gleb 
Published: December 2022

Abstract
We study the two-dimensional Langevin dynamics of a mixture of two types of particles that live respectively at two different temperatures. Dynamics is constrained by an optical trap and the dissimilar species interact via a quadratic potential. We realize that the system evolves toward a peculiar non-equilibrium steady-state with a non-zero probability current possessing a non-zero curl. This implies that if the particles were to have a finite-size and therefore a rotational degree of freedom, they would experience a torque generated by the non-zero local curl and spin around their geometric centers, like ‘spinning top’ toys. Our analysis shows that the spinning motion is correlated and also reveals an emerging cooperative behavior of the spatial components of the probability currents of dissimilar species.

Published: December 2022

Abstract
Brick plays an important role in the construction industry due their excellent properties like compressive strength and durability. From the earliest times they were considered an important factor in the purpose of the building. Considering the different types of bricks, fly bricks are the best in recent times because they are resource intensive and cost effective. This article provides an up-to-date review of current studies of bricks, categorizing these publications according to the materials used and the methods used for the production of invention bricks. In addition, this article makes an important note about coal ash, which may be the focus of future brick products as an alternative to fly-gray bricks with some amount of steel slug, and the main challenge is to go one step further in the properties of the bricks by implementing the respective requirements.

Abstract
Structure collapse, on the other hand, is a very complicated phenomenon involving considerable nonlinearity and a variety of mechanical interactions. It should be thoroughly examined through experiments and numerical simulations to prevent the occurrence from occurring. When initial local failure of a small portion of the structure takes place it leads to the spread of that local damage to neighbor elements in the chain reaction manner. Finally, collapse takes place. This is known as Progressive collapse. This progressive collapse takes place when vertical load carrying members such as columns failed due to manmade or natural accidental loads. Therefore in this study progressive collapse analysis of a building is carried by removing columns. In the analysis different column removal cases are considered. As per GSA guidelines, Demand Capacity ratio(DCR) of beams are calculated. From this DCR value Evaluate the stability of the structure against progressive collapse. In the present study “T”shape building is considered which consists of 11 storey with bay sizes as 4 meter in the X and Y direction, height of every storey is 3 meters and height from the plinth to the floor is assumed 3.5 meters. The measurements of the beams are fixed throughout the storey, but column dimensions decrease as the floor rises, therefore the structure is considered to have geometrical irregularity. The loading is calculated in accordance with G.S.A guidelines. The design was created using the ETABS software and the I.S 456-2000 code. Different parameters such as Demand-capacity ratio, Dynamic factor, Interaction ratio, Axial Force, Bending moment are discussed.
