Bu araştırmanın amacı, 10. Sınıf öğrencilerinin eleştirel, yansıtıcı ve yaratıcı düşünme becerilerinin matematik dersine karşı tutum ve başarısına etkisini incelemektir. Nicel yöntemlerden karşılaştırmalı tarama yönteme göre yürütülen araştırmanın çalışma grubu, Konya ilinde farklı liselerde 10. Sınıfta öğrenim gören 304 öğrenciden oluşmaktadır. Araştırmada veri toplama araçları olarak araştırmacı tarafından geliştirilen 10. Sınıf matematik dersi başarı testi ve ölçeği oluşturan kişilerden izinler alınarak kullanılan ortaöğretim matematik derslerine yönelik tutum ölçeği, eleştirel düşünme becerileri, yansıtıcı düşünme düzeyini belirleme ve yaratıcı düşünme becerileri ölçekleri aracılığıyla veriler çoklu regresyon yöntemi ile analiz edilmiştir. Araştırma bulgularına göre 10. Sınıf öğrencilerinin düşünme becerileri matematik başarı testi puanlarındaki toplam varyansın yaklaşık %14’ünü açıklamaktadır. Bu anlamlı fark yüksek düzeyde bir etkiye işaret etmektedir. Ayrıca regresyon analizi bulgularına göre düşünme becerilerine ilişkin yordayıcı değişkenlerden sadece yaratıcı düşünme ölçeğinin cesaret ve şüphe etme boyutlarının matematik dersi başarısının anlamlı yordayıcısı sonucu bulunmuştur. Diğer taraftan 10. Sınıf öğrencilerinin düşünme becerileri matematik dersine yönelik tutum puanlarındaki toplam varyansın yaklaşık %5’ini açıklamaktadır. Bu anlamlı fark düşük düzeyde etkiye sahip olduğu görülmüştür. Regresyon analizlerine göre, düşünme becerilerine ilişkin yordayıcı değişkenlerden sadece yansıtıcı düşünme becerileri ölçeğinin anlama ve alışkanlık boyutlarının matematik dersine yönelik tutumları anlamlı düzeyde etkilediği sonucuna ulaşılmıştır. Bu sonuçlardan hareketle matematik öğretim programlarında düşünme becerilerine öncelik verilmesi, matematik dersinin öğretim süreçlerinde düşünme becerilerini aktif kılacak şekilde öğretmenin donanımlı ve yetkin olması, öğretmenlerin matematik dersine başlamadan önce, matematik tutum anketi uygulayarak öğrencilerinin matematiğe olan ilgisini belirlemesi önerilir.

Published: October 2023

Criminals or convicts placed in detention centers or prisons with the provisions of the law actually aim to provide a deterrent effect and provide religious understanding so that after the detention period is over they can behave better and not make the same mistakes. However, many of them, after leaving detention, no longer have the trust of the local community where they come from, so that it is difficult for these ex-convicts to get jobs and do not have the skills to become entrepreneurs. This is what makes ex-convicts lose confidence and even repeat the same mistakes. The method of delivering learning material uses a participatory learning approach by providing material and implementing practices. The implementation of this community service activity was carried out at the Bengkulu IIB Prison which was attended by 30 convicts. The Community Service Implementation Team has provided motivation and tips for success for prisoners, conducted cosmetology and beauty training based on the use of domestic production technology, and introduced other alternatives for sources of income such as the manufacture and marketing of organic masks intended for women. convicts as provisions in improving their health. skills at the Class IIB Correctional Institution of the Bengkulu Ministry of Law and Human Rights. Therefore, the service team hopes that from this service the prisoners will gain alternative skills in welcoming the prisoner's free period later.

Published: October 2023

Dalam proses belajar mengajar khususnya di sekolah dasar, guru memiliki peran untuk menjadi fasilitator bagi siswa ketika belajar di sekolah. Banyak siswa yang mengalami bermacam kesulitan belajar di sekolah. Karena itu, orang tua pun berperan penting guna membimbing dan mengajarkan anaknya kala mengalami kesulitan belajar di rumah agar, kesulitan belajar di sekolahnya dapat teratasi melalui pembelajaran yang efektif saat anak berada di rumah. Namun demikian, tidak semua orang tua mampu mendampingi anak selama belajar di rumah. Hal tersebut dikarenakan sebagian orang tua anak-anak di desa Babadan ini bermata pencaharian sebagai petani. Dengan mata pencaharian tersebut para orang tua menjadi harus bekerja seharian, sehingga mereka tidak memiliki banyak waktu untuk mendampingi anak di rumah. Mereka sadar terhadap kurangnya arahan pada anak-anak ketika mereka alami kesulitan belajar di rumah. Hal ini mengakibatkan turunnya motivasi belajar anak sebab tidak memperoleh solusi dari kesulitannya. Maka turunnya motivasi belajar anak tersebut menjadi latar belakang dibutuhkan adanya bantuan pendampingan belajar di rumah untuk siswa-siswi sekolah dasar desa Babadan. Program pendampingan belajar ini diharapkan dapat membantu dalam menyelesaikan kesulitan serta mendorong memotivasi belajar saat di rumah. Kegiatan ini bertempat di Dusun Sumberkunci Desa Babadan Kabupaten Malang. Pelaksanaa program ini terealisasi dan berjalan baik meskipun terdapat kendala tempat yang kurang memadai.

Published: October 2023

Son yıllarda, tıbbi cihazlara bağlı basınç yarası gelişimi hem hastalar hem de sağlık profesyonelleri için önemli bir yük oluşturmaya devam etmektedir. Tıbbi cihazlar, yeni doğanlardan yaşlılara kadar her yaştan hastada meydana gelebilen basınç yarasına neden olabilmektedir. Deri, mukoza ve bu yapıların altındaki yumuşak dokularla etkileşime giren tıbbi cihazlar, oluşturdukları basınç nedeniyle önemli hasarlara yol açmaktadır. Sağlık bakım hizmeti verenler; hastanede yatarak tedavi gören hasta bireylerin basınç yarasının tespiti, önlenmesi, riskinin değerlendirilmesi ve iyileştirilmesi konusunda önemli roller üstlenirler. Tıbbi cihaza bağlı basınç yarası, hasta bireyin tedavisinin neden olduğu istenmeyen bir durumdur. Buradan anlaşıldığı üzere tıbbi cihaz kaynaklı oluşan basınç yarası aynı zamanda bir sağlık hizmeti komplikasyonu olarak değerlendirilebilir. Tıbbi cihaza bağlı basınç yarasının oluşmaması için iyi bir risk değerlendirmesinin yapılması oldukça önemlidir. Hastanın bakımından ve sürekli takibinden sorumlu hemşireler uzun süreli tıbbi cihaz uygulanan hastaların basınç yarası riskini ölçebilmeli, tıbbi cihazın yaptığı basınca yönelik bütüncül bir yaklaşım sergileyerek değerlendirebilmelidir.

Bu derleme tıbbi cihaza bağlı basınç yarası gelişimine neden olabilecek risk faktörlerinin belirlenmesi ve önlenmesi ile ilgili yeterli çalışma olmamasından aynı zamanda tıbbi cihaza bağlı basınç yarası gelişen hastaların bakımında kapsamlı analiz yapabilmeyi sağlayacağı düşüncesiyle yola çıkılarak konuya dikkat çekmek amacıyla hazırlanmıştır.

We apply the techniques developed in our previous article to describe some interesting families of ALF gravitational instantons with conical singularities. In particular, we completely understand the 5-dimensional family of Chen-Teo metrics and prove that only 4-dimensional subfamilies can be smoothly compactified so that the metric has conical singularities.
Detecting Technosignatures from Earth-scale Civilizations
Authors: Ashtari Reza
Published: October 2023

Assuming civilizations have similar interplanetary communications and radar capability to NASA’s Deep Space Network, what is the feasibility of intercepting their communications? Interplanetary conjunctions between Earth-like exoplanets, their stars, and other planets in their systems provide one of the most unique and pragmatic opportunities for detecting technosignatures. While eavesdropping on terrestrial communications becomes limited by a planet’s rotation, the beams of satellite communications and interplanetary radar transmissions are tracked, providing the most persistent and powerful opportunity for signal interception. In this study, we present a framework for assessing exoplanet habitability and establishing quantitative bounds for detecting Earth-scale technosignatures from Earth-like planets. These constraints for time, frequency, sky positions, and observatory sensitivity provide recommended observational guidelines for using state-of-the-art and future ground-based radio observatories toward technosignature detection. Applying this framework, 16 exoplanet targets are proposed for radio observation.
Panchromatic Simulated Galaxy Observations from the NIHAO Project
Authors: Faucher Nicholas , Blanton Michael R. , Macciò Andrea V.
Published: October 2023

We present simulated galaxy spectral energy distributions (SEDs) from the far-ultraviolet (FUV) through the far-infrared (FIR), created using hydrodynamic simulations and radiative transfer calculations, suitable for the validation of SED modeling techniques. SED modeling is an essential tool for inferring star formation histories from nearby galaxy observations, but it is fraught with difficulty due to our incomplete understanding of stellar populations, chemical enrichment processes, and the nonlinear, geometry-dependent effects of dust on our observations. Our simulated SEDs will allow us to assess the accuracy of these inferences against galaxies with known ground truth. To create the SEDs, we use simulated galaxies from the Numerical Investigation of Hundred Astrophysical Objects suite and the radiative transfer code Stellar Kinematics Including Radiative Transfer. We explore different subgrid post-processing recipes, using color distributions and their dependence on axis ratios of galaxies in the nearby Universe to tune and validate them. We find that subgrid post-processing recipes that mitigate limitations in the temporal and spatial resolution of the simulations are required for producing FUV to FIR photometry that statistically reproduce the colors of galaxies in the nearby Universe. With this paper, we release resolved photometry and spatially integrated spectra for our sample galaxies, each from a range of different viewing angles. Our simulations predict that there is a large variation in attenuation laws among galaxies, and that from any particular viewing angle that energy balance between dust attenuation and re-emission can be violated by up to a factor of 3. These features are likely to affect SED modeling accuracy.

quiescent galaxies at 0.5 ≤ z ≤ 3. While massive companions like those identified by HST are rare, JWST imaging from the JWST Advanced Deep Extragalactic Survey reveals that the average massive quiescent galaxy hosts approximately five nearby companions with stellar mass ratios <1:10. Despite a median stellar mass ratio of just 1:900, these tiny companions are so numerous that they represent at least 30% of the total mass being added to quiescent galaxies via minor mergers. While relatively massive companions have colors similar to their hosts, companions with mass ratios <1:10 typically have bluer colors and lower mass-to-light ratios than their host galaxies at similar radii. The accretion of these tiny companions is likely to drive evolution in the color gradients and stellar population properties of the host galaxies. Our results suggest that the well-established “minor merger growth” model for quiescent galaxies extends down to very low mass ratios of ≲1:100, and demonstrates the power of JWST to constrain both the spatially resolved properties of massive galaxies and the properties of low-mass companions beyond the local Universe.
Dissonance in Harmony: The UV/Optical Periodic Outbursts of ASASSN-14ko Exhibit Repeated Bumps and Rebrightenings
Authors: Huang Shifeng , Jiang Ning , Shen Rong-Feng , Wang Tinggui , Sheng Zhenfeng
Published: October 2023

ASASSN-14ko was identified as an abnormal periodic nuclear transient with a potential decreasing period. Its outbursts in the optical and UV bands have displayed a consistent and smooth “fast rise and slow decay” pattern since its discovery, which has recently experienced an unexpected alteration in the last two epochs, as revealed by our proposed high-cadence Swift observations. The new light curve profiles show a bump during the rising stages and a rebrightening during the declining stages, making them much broader and symmetrical than the previous ones. In the last two epochs, there is no significant difference in the X-ray spectral slope compared to the previous one, and its overall luminosity is lower than those of the previous epochs. The energy released in the early bump and rebrightening phases (∼1050 erg) could be due to collision of the stripped stream from partial tidal disruption events with an expanded accretion disk. We also discussed other potential explanations, such as disk instability and star–disk collisions. Further high-cadence multiwavelength observations of subsequent cycles are encouraged to comprehend the unique periodic source with its new intriguing features.
Anthropogenic Coal Ash as a Contaminant in a Micro-meteoritic Underwater Search
Authors: Gallardo Patricio A.
Published: October 2023

Chemical composition for spherules recovered from the search area of CNEOS 2014-01-08 in the Pacific Ocean has been recently released. A three-order of magnitude difference from CI-chondrites has been identified for elements beryllium, lanthanum and uranium in five samples. The lack of consensus regarding atmospheric survival and precision of path estimates motivate an examination of possible contaminants. Contents of nickel, beryllium, lanthanum and uranium are examined in the context of a known anthropogenic source of contamination, and found to be consistent with coal ash as suggested from a publicly available coal chemical composition database (COALQUAL). The meteoritic origin is disfavored.

Inscrits dans un mouvement contemporain de production de connaissances sur la pluralité des contextes et des pratiques de recherche et notamment en Sciences humaines et sociales, nous proposons dans cet article d’interroger un contexte singulier d’apprentissage de la pratique de recherche en géographie. À travers le développement de l’expérience d’un doctorant qui réalise sa thèse dans le cadre d’un dispositif de Convention industrielle de formation par la recherche (Cifre) et d’une recherche pluridisciplinaire et multi-partenariale sur projet, les auteurs appréhendent les spécificités particulières ou non des pratiques de recherche et des adaptations dans ce contexte de travail. A la suite, le doctorant se demande dans quelle mesure son sujet de recherche doctorale a été inspiré et dynamisé par cette étude pluridisciplinaire menée sur les savanes des bas de l’ouest réunionnais. Une approche réflexive a été nécessaire pour investiguer la posture du chercheur en Cifre, les méthodes et les outils mobilisés pour s’adapter à une situation de recherche appliquée et impliquée.
Liaison variable et modèle variationniste labovien : une exception française ?
Authors: Hornsby David
Published: October 2023

Une analyse de la liaison chez 96 élèves de lycée a démontré que le nombre global de liaisons produites a été nettement supérieur en lecture qu’en conversation et que les filles en ont réalisé plus que les garçons. Si ces deux résultats ne surprennent guère, ils vont néanmoins à l’encontre des attentes de la théorie variationniste. Nous soutiendrons que ces deux tendances ont pour facteur commun le rôle de la liaison comme marqueur de l’écrit à l’oral et soulignent le fait que, pour le français du moins, les dimensions formalité et scripturalité doivent être découplées dans toute analyse stylistique.
Meet-in-the-middle differential fault analysis on Midori
Authors: An Chunyan , Bai Wei , Zhang Donglei
Published: October 2023

Midori is a lightweight block cipher designed by Banik et al. and presented at the ASIACRYPT 2015 conference. According to the block size, it consists of two algorithms, denoted as Midori-64 and Midori-128. Midori generates 8-bit S-Boxes from 4-bit S-Boxes and applies almost MDS matrices instead of MDS matrices. In this paper, we introduce the meet-in-the-middle fault attack model in the 4-round cell-oriented fault propagation trail and reduce the key space in the last round by $ 2^{45.71} $ and $ 2^{39.86} $ for Midori-64 and Midori-128, respectively. For Midori-64, we reduce the time complexity from $ 2^{80} $ to $ 2^{28} $, $ 2^{32} $ and $ 2^{56} $ for the different single fault injection approaches. For Midori-128, we provide a 4-round fault attack method, which slightly increases the complexity compared to previous attacks. Our results indicate that the first and last four rounds of Midori must be protected to achieve its security.
Bird sound recognition based on adaptive frequency cepstral coefficient and improved support vector machine using a hunter-prey optimizer
Authors: Chen Xiao , Zeng Zhaoyou
Published: October 2023

Bird sound recognition is crucial for bird protection. As bird populations have decreased at an alarming rate, monitoring and analyzing bird species helps us observe diversity and environmental adaptation. A machine learning model was used to classify bird sound signals. To improve the accuracy of bird sound recognition in low-cost hardware systems, a recognition method based on the adaptive frequency cepstrum coefficient and an improved support vector machine model using a hunter-prey optimizer was proposed. First, in sound-specific feature extraction, an adaptive factor is introduced into the extraction of the frequency cepstrum coefficients. The adaptive factor was used to adjust the continuity, smoothness and shape of the filters. The features in the full frequency band are extracted by complementing the two groups of filters. Then, the feature was used as the input for the following support vector machine classification model. A hunter-prey optimizer algorithm was used to improve the support vector machine model. The experimental results show that the recognition accuracy of the proposed method for five types of bird sounds is 93.45%, which is better than that of state-of-the-art support vector machine models. The highest recognition accuracy is obtained by adjusting the adaptive factor. The proposed method improved the accuracy of bird sound recognition. This will be helpful for bird recognition in various applications.
Theories, Facts, and Meanings in Political Philosophy
Authors: Robson Gregory , Pincione Guido
Published: October 2023

The consequences of correctly implementing a normative political theory arguably bear on its acceptability. A theory whose correct implementation permits slavery is highly implausible. We defend a claim about incorrect implementation. We argue that normative political theories that will predictably be put to bad use deserve harsher assessments than theories that will predictably be put to better use. Theories that key political actors will predictably invoke to justify bad policy recommendations are bad theories, even if those recommendations are not logical consequences of the theories (even in conjunction with well-established factual propositions). However, standard discussions of political theories ignore such “misapplications” when it comes to assessing the principles and values proclaimed by those theories. We reject this view because the action guidance that a normative political theory effectively provides is mediated by political actors’ prior beliefs. At the limit, these actors may regard public policies as specifying principles that the theory proclaims, as something different from regarding such policies as causally effective in achieving the ends or enforcing the rights proclaimed by those principles. As a result, political actors see themselves as exempted from the need to undertake careful causal analysis. Morally defensible action guidance requires, then, that those principles be qualified by empirically-grounded policy constraints. Normative political theories qualified in those ways constitute theoretical improvements, that is, improvements on the action guidance that the theories provide on their own.
Resiliência da ação pública democrática em tempos de crise: examinando as políticas de alimentos e recursos hídricos no Brasil
Authors: Milhorance Carolina , Andrade Marina Lazarotto de , Coq Jean-François le , Sabourin Eric
Published: October 2023

Desde meados dos anos 2010, observou-se um
retrocesso em diversas políticas públicas, intensificado após a
eleição de Jair Bolsonaro. A literatura tem crescentemente analisado
as estratégias de desmonte e os ataques às instituições democráticas,
mas há menos foco na resiliência das burocracias estatais, dos atores
políticos e do próprio regime político. Este artigo, a partir de um
estudo de caso no Semiárido nordestino, aborda duas políticas
inter-relacionadas com participação de atores não estatais: i) a
governança das águas na bacia do rio São Francisco e ii) o acesso à
água e a alimentos agroecológicos. O estudo indica que, apesar da
institucionalização ser um fator de estabilidade, ela não impede
mudanças ou desmonte. Destaca-se também a relevância das redes
informais de políticas públicas em criar alternativas de implementação
e coalizões de resistência a mudanças, incentivando novas respostas
políticas.

Category I anti-tuberculous therapy with a tapering regimen of intravenous dexamethasone was administered.

Outcomes:

There was clinical improvement after nine months of treatment.

Lessons:

Tuberculosis may present with atypical clinical manifestations. Contrast enhanced computed tomography scan or magnetic resonance imaging combined with histopathological features, a high index of suspicion and clinical improvement with anti-tuberculous treatment can confirm the diagnosis in the absence of microbiological evidence, especially in extrapulmonary tuberculosis.

Purpose:

To measure the levels of inflammatory factors in tear fluid of pre-term infants with and without retinopathy of prematurity (ROP).

Methods:

The cross-sectional pilot study included 29 pre-term infants undergoing routine ROP screening. Pre-term infants were grouped as those without ROP (no ROP; n = 14) and with ROP (ROP; n = 15). Sterile Schirmer’s strips were used to collect the tear fluid from pre-term infants. Inflammatory factors such as interleukin (IL)-6, IL-8, MCP1 (Monocyte Chemoattractant Protein 1; CCL2), RANTES (Regulated on Activation, Normal T Cell Expressed and Secreted; CCL5), and soluble L-selectin (sL-selectin) were measured by cytometric bead array using a flow cytometer.

Results:

Birth weight (BW) and gestation age (GA) were significantly (P < 0.05) lower in pre-term infants with ROP compared with those without ROP. Higher levels of RANTES (P < 0.05) and IL-8 (P = 0.09) were observed in the tear fluid of pre-term infants with ROP compared with those without ROP. Lower levels of tear fluid IL-6 (P = 0.14) and sL-selectin (P = 0.18) were measured in pre-term infants with ROP compared with those without ROP. IL-8 and RANTES were significantly (P < 0.05) higher in the tear fluid of pre-term infants with stage 3 ROP compared with those without ROP. Tear fluid RANTES level was observed to be inversely associated with GA and BW of pre-term infants with ROP and not in those without ROP. Furthermore, the area under the curve and odds ratio analysis demonstrated the relevance of RANTES/BW (AUC = 0.798; OR-7.2) and RANTES/MCP1 (AUC = 0.824; OR-6.8) ratios in ROP.

Conclusions:

Distinct changes were observed in the levels of tear inflammatory factors in ROP infants. The status of RANTES in ROP suggests its possible role in pathobiology and warrants further mechanistic studies to harness it in ROP screening and management.
Association between resistivity index of central retinal artery and severity of diabetic retinopathy
Authors: Pillai Gopal S , Kutumbaka Akhila , Nazar P K , Chandiri Anvesh , Ravindran Greeshma C
Published: October 2023

Purpose:

Diabetic retinopathy (DR) is a leading cause of ocular morbidity. Its progression depends mainly on retinal vasculature and ocular blood flow. Color Doppler imaging (CDI) is a noninvasive imaging technique that measures blood flow velocity. The resistivity index (RI), calculated by the CDI, reflects the vascular resistance distal to the measuring location. RI is independent of the doppler angle and position of the patient, making it a reliable and reproducible parameter. To the best of our knowledge, there is only one study in literature studying the association between resistivity index (RI) of the central retinal artery (CRA) and severity of DR.

Aim:

To determine the association between RI of CRA and severity of DR. To determine the association between RI of CRA and spectral-domain optical coherence tomography (SD-OCT) biomarkers for DR.

Methods:

Type II diabetics visiting our OPD underwent DR screening and were graded into three categories according to ETDRS classification which include Group A—No diabetic retinopathy (No DR), Group B—Nonproliferative diabetic retinopathy (Moderate–Severe–Very Severe NPDR), and Group C—Proliferative diabetic retinopathy (PDR). SD-OCT was performed. Ultrasonic color doppler imaging was done. RI of the CRA was noted. It was compared between the three groups and its association with severity of DR and OCT biomarkers (central subfield thickness, cube average thickness and ellipsoid zone disruption) was studied.

Results:

56 eyes of 28 patients were included in our study with 20 in Group A,14 in Group B, and 22 in Group C. RI of CRA compared within groups showed statistically significant association with severity of DR (P < 0.001). The presenting BCVA (LogMar) showed positive correlation with RI in all groups. OCT biomarker central subfield thickness showed a positive correlation with RI in Groups A (P < 0.001) and B. Ellipsoid zone (EZ) disruption showed a statistically significant association with RI in Group C (P < 0.001).

Conclusion:

The RI of CRA is a reliable biomarker for the assessment of the severity of DR. Patients with high RI of CRA had higher chances of EZ disruption and presented with poor visual acuity.
Long and short of Ahmed glaucoma valve tube
Authors: Mansoori Tarannum , Saleem Shaima
Published: October 2023

Background:

The Ahmed Glaucoma Valve (AGV, New World Medical Inc., Rancho Cucamonga, CA, USA) is a glaucoma drainage device commonly used in the treatment of refractory glaucoma either as a primary surgical procedure or after the failure of conventional filtration procedures. During surgery, After the AGV plate is fixed to the sclera, at least 8 mm posterior to the corneoscleral limbus, the length of tube is trimmed to the desired length, based on decision to insert it in the anterior chamber (AC) or ciliary sulcus.

Purpose:

This video describes that the length of AGV silicone tube should be cut based on decision to place it in the AC or ciliary sulcus. The tube should not be cut too long or short as in either case it may cause postoperative complications.

Synopsis:

The video illustrates useful tips for AGV tube insertion into the AC, taking care that it does not cross pupillary margin and is of adequate length. The silicone AGV tube is cut using Westcott scissors to permit a length of 2- to 3-mm tube insertion in the AC, with its bevel facing up, and the tip is cut to an angle of 30°, to facilitate AC entering. In ciliary sulcus placement of the AGV tube, the tunnel is made longer when compared with the AC implantation, and the length of tube should be kept long enough for the tip to be just visible beyond the pupillary border.

Highlights:

This video highlights the importance of customization of the AGV tube length for individual patients based on its placement into AC or ciliary sulcus.

Single-cell transcriptomics in thyroid eye disease
Authors: Ahsanuddin Sofia , Wu Albert Y.
Published: October 2023

Thyroid eye disease (TED) is a poorly understood autoimmune condition affecting the retroorbital tissue. Tissue inflammation, expansion, and fibrosis can potentially lead to debilitating sequelae such as vision loss, painful eye movement, proptosis, and eyelid retraction. Current treatment modalities for TED include systemic glucocorticoids, thioamides, methimazole, teprotumumab, beta-blockers, and radioactive iodine; however, it has been reported that up to 10%–20% of TED patients relapse after treatment withdrawal and 20%–30% are unresponsive to mainstay therapy for reasons that have yet to be more clearly elucidated. In the past 4 years, vision researchers have harnessed high-throughput single-cell RNA sequencing to elucidate the diversity of cell types and molecular mechanisms driving the pathogenesis of TED at single-cell resolution. Such studies have provided unprecedented insight regarding novel biomarkers and therapeutic targets in TED. This timely review summarizes recent breakthroughs and emerging opportunities for using single-cell and single-nuclei transcriptomic data to characterize this highly complex disease state. We also provide an overview of current challenges and future applications of this technology to potentially improve patient quality of life and facilitate reversal of disease endpoints.

Published: October 2023

Prolonged urinary incontinence represents one of the most severe complications after a radical prostatectomy procedure, significantly affecting patients’ quality of life. In an attempt to ameliorate postprostatectomy continence rates, several sphincter preservation techniques have been reported. The purpose of this article is to report several different sphincter preservation techniques and identify the ones which affect postoperative outcomes the most. For our narrative review, PubMed was searched using the keywords “sphincter,” “continence,” “preservation,” “techniques,” and “prostatectomy.” Other potentially eligible studies were identified using the reference lists of included studies. Sphincter preservation techniques can be summarized into bladder neck preservation, minimizing injury to the external urethral sphincter, and preserving the maximal length of the external sphincter and of the membranous urethra. Three anatomical structures must be recognized and protected in an attempt to maintain the sphincter complex: the bladder neck, the external urethral sphincter and the musculature of the membranous urethra. While there is strong evidence supporting the importance of bladder neck preservation, the role of maximal preservation of the external sphincter and of the intraprostatic part of the membranous urethra in improving continence rates has not yet been reported in a statistically significant manner by high-quality studies.

Published: October 2023

Background:

Bladder cancer is one of the most common cancers worldwide. Expression of cytokeratin 20 (CK 20) could be used as a biomarker in different epithelia to determine malignancy, especially in gastrointestinal, urinary tract, and Merkel cells. CK 20 could be detected in several urothelial carcinomas and was associated with bladder cancer recurrence. The study aimed to assess the utility of CK 20 expression for bladder cancer grading.

Materials and Methods:

This was a retrospective study assessing CK 20 expression in 73 bladder cancer patients who had transurethral resection of bladder tumor or cystectomy. The data were then collected and analyzed with SPSS Statistics version 20.0.

Results:

Fifty-six (76.7%) cases of high- and 17 (23.3%) cases of low-grade urothelial bladder cancer were examined for CK 20 expression. Positive expression was present in 57 (78.1%) samples. A significant difference (P = 0.034) in CK 20 expression was observed between low-grade and high-grade urothelial carcinomas. Positive expression was seen in 44 (77.2%) high-grade cases and only 13 (22.8%) low-grade cases.

Conclusion:

The difference in the CK 20 expression was found to be statistically significant among different grades of bladder cancer but not to metastatic bladder cancer. Further, studies are required to establish CK 20 as a diagnostic tool. We suggest a combination with several markers to compare which is superior.
