Transition from maternal chronic renal failure to peritoneal dialysis treatment
No full textChronic kidney failure (CKF) has become an increasingly important public health issue in our country and worldwide. According to data systems in our country, as of the end of 2022, there were a total of 86,665 patients with chronic kidney failure, and 4.1% of these patients undergo peritoneal dialysis treatment. Peritoneal dialysis requires active participation of the patient in the treatment, and it can lead to negative effects on body image, self-esteem, and sexual relations due to the peritoneal dialysis catheter, causing anxiety and depression in patients and negatively affecting their quality of life. Throughout human life, individuals undergo changes in identity, roles, responsibilities, abilities, and behaviors due to various reasons (illness, pregnancy, death, birth). One of the fundamental duties of nurses is to assist individuals undergoing various transitions in their lives, to support healthy transitions, and to minimize unhealthy transitions. In this study, the process of transition experienced by a healthy woman transitioning to the role of motherhood due to health problems during pregnancy, and transitioning to chronic kidney failure and peritoneal dialysis treatment, is examined based on Meleis' Transition Theory
Dyspnea management in palliative care
No full textDispne, kanser hastalarının yaygın olarak yaşadığı, ciddi acılara neden olan, hastanın hastalık gidişatı boyunca kötüleşen ve tedavisi diğer semptomlara göre daha zor olabilen bir semptomdur. Dispnenin değerlendirilmesi en iyi subjektif bir tanımlamayla gerçekleştirilir; Fizyolojik ölçümler hastanın deneyimiyle yalnızca zayıf bir korelasyona sahiptir. Kanser hastalarında dispnenin olası malign ve malign olmayan nedenlerini geniş bir yelpazede göz önünde bulundurmak ve mümkünse altta yatan nedenleri düzeltmek önemlidir. Dispnenin yönetiminde farmakolojik yöntemlerden en çok benzodiazepinler tercih edilmektedir. Hastalar hipoksemikseye ek olarak kronik obstrüktif akciğer hastalığı varsa oksijen desteği almalıdırlar.
Bunun yanında fan terapisi, egzersiz programları ve pulmoner rehabilitasyon gibi farmakolojik olmayan yöntemlerde kullanılmaktadır. Dispne yönetiminde hızlı değerlendirme ve tedavi, hastalar için semptomların ve sonuçların iyileştirilmesi açısından hayati öneme sahiptir. Her ne kadar nefes darlığı kanser hastalarında yaygın ve potansiyel olarak zayıflatıcı olsa da, uygun terapötik stratejiler kullanılarak hastayı tedavi ederken aynı zamanda geri döndürülebilir nedenleri dışlayacak yapılandırılmış bir yaklaşımla etkili bir şekilde yönetilebilir.Dyspnea is a symptom commonly experienced by cancer patients that causes significant suffering, may worsen in the future, and may be more difficult overall than the ongoing course. Assessment of distribution is best described as subjective; It has only a poor appearance by experience of physiological measurements. It is important to consider a wide range of possible malignant and non-malignant causes of dyspnea in cancer patients and, if possible, to treat the underlying diseases. Benzodiazepines are the most preferred pharmacological doses for dyspnea. Patients should receive oxygen support if they have chronic obstructive pulmonary disease in addition to being hypoxemic. In addition, it is used in non-pharmacological methods such as fan therapy, exercise programs and pulmonary distribution. The delivery system is strategically vital for rapid evaluation and treatment, devices and outcomes. Although shortness of breath is common and potentially debilitating in cancer patients, it can be effectively
managed with appropriate therapeutic strategies to treat the patient while also ruling out recurrent causes
The mapping of photographer’s studio in İzmir 1900-1950: From Frank Street to Kemeraltı
No full textThe purpose of this study is to discuss the link between the photographer and the city based on a close reading of the historical dislocation and the transformation of urban space. Therefore, it is possible to say that both in the past and today, migrations are changing urban spaces by influencing the social, cultural, and economic structures in cities. In this context, the study focuses on the mappings produced in photographer's studios in Izmir between 1900 and 1950. Mapping is a creative method that accommodates various representation possibilities and that consequently propounds unpredictable relationships. In this framework, in order to show both the experiences of the exile and their reflection in urban spaces, the network of photographers in the city have been visually analyzed. Before 1922, 62 photographers were active in İzmir. Around half of them were from Levantine or Armenian origin who settled in Izmir, and their studios were situated on the Frank and the Rose Streets of the city. After 1922, Turkish-Muslim photographers replaced them. Most of these Turkish-Muslim immigrant photographers preferred to open their studios around Kemeraltı as a significant commercial zone. Habits of urban space use and the Kemeraltı region were reshaped and defined together with the existence of these immigrants
Using loofah reinforced chitosan-collagen hydrogel based scaffolds in-vitro and in-vivo; healing in cartilage tissue defects
No full textThe herein article aims to report a new scaffold design as a loofah-reinforced chitosan-collagen hydrogel composite scaffold with three different cross-linker concentrations (0.1, 0.3, and 0.5 wt. /v%). From the analyses, the scaffold crosslinked with 0.5% genipin; collagen-chitosan hydrogel scaffold reinforced with loofah (L-CCol5) was found to be suitable for further in vitro and in vivo studies due to its interconnected porous structure, water content (∼ 97%) and tan delta (0.221 at 1 Hz) values comparable to that of cartilage tissue. In vitro analyses depicted that the L-CCol5 scaffold supported rabbit mesenchymal stem cells (rMSCs) adhesion and proliferation with its non-cytotoxic feature. Moreover, in vivo cartilage healing studies were performed using New Zealand male rabbits in three groups: empty control, cell-free scaffold, and rMSCs-laden scaffold. The elastic moduli of these three groups were 0.69, 0.90, and 1.18 MPa, respectively. Besides, microcomputer tomography (MicroCT) scannings supported the in vivo biomechanical analyses as cell-laden scaffolds showed better osteochondral healing. It can be concluded that the L-CCol5 scaffold could be a promising construct in osteochondral tissue engineering applications. The findings revealed that osteochondral remodeling precedes articular cartilage, providing insight into tailored therapeutic approaches, disease progress, and treatment consequences
CVD graphene/SiC UV photodetector with enhanced spectral responsivity and response speed
No full textA self-powered, high-performance graphene/Silicon Carbide (G/4H-SiC) ultraviolet Schottky junction photodetector has been fabricated, and the effect of using monolayer and bilayer graphene on the device performance parameters was investigated. P-type graphene sheets were grown by the chemical vapor deposition (CVD) method, while 4H-SiC material consists of an epilayer structure of n-/n+ on bulk n-SiC. Two photodetector devices have been studied, one with monolayer graphene (MLG) and the other with bilayer graphene (BLG). The proposed photodetector structure reveals the highest spectral responsivity known of a G/4H-SiC UV photodetector so far. Electronic and optoelectronic characterizations were done under an ultraviolet wavelength range from 240 to 350 nm. The results show two spectral responsivity maxima (Rmax) at 285 nm and 300 nm wavelengths. Exhibiting two maxima in spectral responsivity and detectivity is caused by the constructive and destructive interference effects of multiple reflections at the SiC epilayer's interfaces. The photodetector devices exhibit high spectral responsivity (R ∼ 0.09 AW−1), maximum detectivity (D* ∼ 2.9 × 1012 Jones), and minimum noise equivalent power (NEP ∼ 0.17 pWHz-1/2) in both devices. Using bilayer graphene instead of monolayer showed no significant change in both the photogenerated current and the spectral responsivity due to the higher absorption coefficient of bilayer graphene, however, it exhibited a significant improvement in the response speed. The response speed was found to increase by 50 % when bilayer graphene was used as a hole collecting electrode in the G/4H-SiC junction. This is because bilayer graphene creates a narrower depletion layer and higher electric field, which promotes efficient charge separation and recombination
Systematic review and meta-analysis of depressive symptom severity of employed and unemployed women in Turkey
No full textDepression which is one of the mood disorders, causes a decrease in the work that requires participation during the day, and affects interpersonal relationships. It is known to be a fairly common mental disorder, especially among women. The aim of this systematic review is to investigate the effect of women’s employment status on the severity of depressive symptoms in Turkey.
Method: We searched the databases of YÖK Thesis Center, ULAKBIM, Web of Science and Scopus to detect those studies aiming to compare the employed women with housewives in terms of the depressive symptoms measured with validated self-report scales in Turkish.
Results: Of the 283 studies reported in Turkish or English as an article or dissertation, 10 met the inclusion criteria for meta-analysis. The random effects meta-analysis conducted with R 4.0.1, meta and metafor package revealed a slight and statistically nonsignificant effect of the employment status on women’s depressive scores (g=-0.13 95% Confidence Interval [CI] [-0.41, 0.14]). Heterogeneity between studies was estimated at a high level (I2=90.3% 95% CI [84.3%, 94%]). Results of the metaregression analyses implied that neither the sample size (R2=0.00%) nor the publication year (R2=5.58%) were among the main sources the heterogeneity. The findings suggest that the risk of having depressive symptoms is nearly same in employed women as in housewives.
Discussion: Hence, employment status is unlikely to be among the main factors leading to relatively higher prevalence of depression among women
Geriatric oncological emergencies: bibliometric analysis
No full textIntroduction and Purpose: The World Health Organization has reported that by the year 2030, one in every six people globally will be aged 60 and above. With the global aging of the population, there is also an increase in cancer cases among elderly individuals. Emergency situations related to cancer often arise due to malignancy and treatment-related syndromes. These urgent situations, which require rapid assessment, frequently manifest as geriatric syndromes in elderly individuals. This research aims to identify and visualize articles on the relationship between geriatric patients and oncological emergencies, delineate trends, and provide researchers in the future with a literature-based overview of the subject.
Materials and Methods: Data were obtained from the "Web of Science Core Collection" database on November 24, 2023. The analysis of the obtained data was conducted bibliometrically using the "R-based Bibliometrix" program for performance analysis and scientific mapping. A search with the keywords 'elderly,' 'emergency,' and 'oncology' in the WoS database yielded a research population of 125. The analysis included the number of publications, authors, countries, and keywords by year.
Results: The analysis revealed that the most commonly used keywords in the Web of Science category were "elderly-patients," "survival," and "mortality." When evaluating the countries where the studies were conducted, the United States (n:34), China (n:17), Italy (n:14), and Canada (n:8) were found to be the top contributors, with the highest number of publications in 2021 (n:15) and 2022 (n:15). The number of publications has been increasing since 2011. In terms of publication categories, oncology (n:83) was identified as the category with the most studies. The author who contributed the most to publications on the researched keywords was identified as "Procopio Giuseppe" (n:3).
Conclusion: The results of this study are expected to contribute to the identification and evaluation of geriatric oncological cases, providing insights for current assessments and guiding future research
Palyatif bakımdan bir kesit: son dönem böbrek hastalıkları
No full textPalyatif bakım yaşamı tehdit eden kronik hastalıkların artmasıyla hasta ve aileler için özellikle ihtiyaç haline gelmiş multidisipliner bir bakım anlayışını içeren bir disiplindir. Modern palyatif bakım kavramında yaşamı tehdit eden hastalıkların erken teşhis döneminde palyatif bakım kavramlarının uygulanması varsayılsa da palyatif bakım kliniklerinin büyük bir kısmı aktif olarak yaşamın son evresinde olan hastaların ve ailelerin bakımı ve yas sürecinin planlanması ile ilgili uygulamaları içermektedir. Palyatif bakımda kastedilen yaşamı tehdit eden hastalık birçok kronik hastalık biçimini içerebilir. Yaşam kalitesini bozan, tedavi süreci uzun ve yorucu olan, hayatta kalma beklentisi düşük olan; akut veya kronik böbrek hastalığı (KBH) olan hastalar da palyatif bakım merkezlerinde tedavi görmesi gereken hasta gruplarıdır. Geçmiş yıllarda kronik böbrek hastalığına yönelik verilen palyatif bakım hizmetleri yetersiz olmuştur.
Hastaların semptomlarının yönetilememesi ve hastaların sık hospitalizasyonu palyatif bakıma gereksinimin arttığının altını çizmiştir. Tüm bunların yanı sıra yeni bir ölümcül hastalık tanısı alan veya hastalık prognozunun kötüye gitmesi nedeniyle diyalizden çıkan hastaların palyatif bakımda tedavi görmesi gündeme gelmiştir. Bunun yanında tanı aldığı günden itibaren diyaliz tedavisine başlamayı hiç kabul etmemiş hastalar da olabilir ve onlar da palyatif bakıma ihtiyaç duyabilir. Bu yüzden tüm bunlar göz önüne alınarak günümüzde artık ilerlemiş kronik böbrek hastalığı (KBH) olan hastalar için palyatif bakımın gerekliliği uzmanlarca kabul edilmiştir
The dynamic relationship between BTC with bist and nasdaq indices
No full textThe significance of digital investment has grown substantially, enabled by advancing technology, which provides digital monitoring of investment instruments. Consequently, analyzing these in-struments has become imperative. In particular, investors are inclined to compare new invest-ment opportunities with well-established global stock markets, seeking to capitalize on their advanced financial literacy. This study aims to employ econometric analysis to explore the dy-namic relationship between Bitcoin and the BIST100 and NASDAQ 100 indices. The time frame for this investigation spans from January 1, 2017, to March 10, 2022. Stationarity was confirmed through unit root tests (ADF, PP, KPSS, ZA, FADF, and FFFFF ADF) for the subsequent utilization of Autoregressive Conditional Variance Models. Additionally, Generalized Autoregressive Condi-tional Variance and Dynamic Conditional Correlation Tests were conducted. Results from the Dynamic Conditional Correlation Test model revealed no statistically significant dynamic condi-tional correlation between Bitcoin and BIST 100. Conversely, a negative and significant dynamic conditional correlation emerged between Bitcoin and NASDAQ 100. Investors should not only monitor the market but also review academic studies before making investment decisions. In this regard, this study holds significant importance. The study is limited to the BTC, BIST, and NASDAQ indices. Researchers interested in the topic can increase the dataset to further enrich the study
An Assessment of the outstanding universal value of the Mardin cultural landscape area and the UNESCO world heritage list nomination process
No full textİnsanoğlu, tarih boyunca kendi ürettiklerini koruma isteği duymuştur. Süreç içerisinde koruma yaklaşımları değişmiş, zamanla tek yapı ölçeğinden yapı gruplarına ve yerleşme ölçeğine doğru evirilmiştir. Bu bağlamda “koruma” olgusu, yaşam alanlarında üretilen somut ve somut olmayan değerleri kendi kapsamına alarak genişlemiştir. Bu amaçla, geçmişten devralınan ve geleceğe taşınmak istenen; evrensel niteliklere sahip ve insanlığın ortak mirası olan kültürel ve doğal değerler koruma altına alınmaktadır. UNESCO, uluslararası önem taşıyan ve bu nedenle takdire ve korunmaya değer doğal oluşumlara, anıtlara ve sitlere “Dünya Mirası” (DM) statüsü vermektedir. UNESCO tarafından 17 Aralık 1975 yılında yürürlüğe giren “Dünya Kültürel ve Doğal Mirasının Korunmasına Dair Sözleşme” ile bu değerler evrensel bir boyutta korumaya alınmıştır. Türkiye’de 1983 yılında taraf devlet olarak ilgili sözleşmeyi kabul etmiştir. Böylece Türkiye’deki doğal ve kültürel değerler de evrensel boyutta dünya mirası listesine girmeye başlamışlardır. 2000 yılından beri geçici listede yer alan ve Dünya Mirası Listesi’ne aday olan Mardin, M.Ö. 2000’ler den bu yana birçok medeniyete ev sahipliği yapmış ve halen günümüzde de çok renkli ve çok katmanlı sosyo-kültürel ve fiziki yapıya sahip kadim bir kenttir. Tarihi yapıları ve dokusu ve sosyo-kültürel bileşenleriyle dünya mirası niteliği taşıyan kent, somut ve somut olmayan kültürel değerleriyle kültürel peyzaj adına önemli bir örnek teşkil etmektedir. Yerinde yapılan gözlemler ile birincil ve ikincil kaynaklarınincelenmesiyle literatür değerlendirilmesi yapılarak çalışmanın yöntemi belirlenmiştir. Bu çalışmada, Mardin’in Dünya Mirası Listesi’ne (DML) adaylık süreci, kentin tarihî belleği ile yapıları, kültürel kimliği ve sahip olduğu Üstün Evrensel Değerlerin (ÜED) ortaya konması hedeflenmektedir. Bu bağlamda bu çalışmayla varılmak istenen sonuçta kent için yapılan tüm müdahaleler değerlendirilerek, Mardin’in bir bütün olarak somut ve somut olmayan değerlerinin gelecek kuşaklara aktarılması ve “kültürel peyzaj” kavramı olarak Dünya Miras Listesi’nde yer alması için öneriler sunulmuştur.Human beings have felt the desire to preserve their own production throughout history. In the process, protection approaches have changed, and over time, they have evolved from single structure scale to structure groups and the settling scale. In this context, the phenomenon of “protection” has expanded by taking the tangible and untangible values produced in living areas into its own context. To this end, cultural and natural values, which are inherited from the past and are wanted to move to the future, are protected by universal qualifications and the common legacy of humanity. UNESCO gives the status of “World Heritage”(WH) to natural formations, monuments and sites that are internationally important and therefore worthy of admiration and protection. The values are protected in a universal dimension with the “Convention on the Protection of World Cultural and Natural Heritage”, which was implemented by UNESCO on December 17, 1975. In 1983, Turkey adopted the relevant agreement as the entity state. Thus, the natural and cultural values in Turkey have started to enter the universal-sized world heritage list. Mardin has been on the temporary list since 2000 and has been nominated for World Heritage List. It has been home to many civilizations since the 2000 B.C. and is now an ancient city with mul-ticolor and multi-layered socio-cultural and physical structures. The city,which is characterized by its historical structures and texture and socio-cultural components as world heritage, is an important example of cultural landscape with its tangible and untangible cultural values. The method of study was determined by evaluating literature by examining primary and secondary sources with onsite observations. In this study, the nomination process for. Mardin’s World Heritage List (WHL) is intended to reveal the historical memory and structures of the city, its cultural identity and its outstanding Universal values(OUV). In this context, all the interventions made for the city were evaluated and recommendations were made to transfer Mardin's tangible and untangible values as a whole to future generations and to be included in the World Heritage List as the concept of “cultural landscape”
