Authors: TUNAKAN DALGIÇ Ceyda 
Published: September 2023

Background-Aims: Drug hypersensitivity is defined as any unfavorable reaction that occurs after the administration of any drug. We aim to determine the frequency, etiology, and clinical features of drug hypersensitivity reactions (DHRs), and to evaluate the factors affecting drug-related anaphylaxis among the patients admitted to the outpatient allergy clinic of the tertiary university hospital.
Materials-methods: In this cross-sectional study, medical records of the 8295 patients who visited the allergy outpatient clinic of Sivas Cumhuriyet University Hospital from 2nd July 2018 to 10th December 2019 were retrospectively reviewed by the hospital data system using the ICD-code Y57.4. The frequency, etiologies, demographic and clinical features of the DHRs were evaluated.
Results: Among the 8295 patients who visited the allergy outpatient clinic of Sivas Cumhuriyet University Hospital, 159 patients with a mean age of 40,52± 14,85 years (129 female, 30 male) were evaluated with the diagnosis of DHRs. The frequency of DHRs among admissions was found to be approximately 2%. Accompanying allergic diseases included respiratory (17%), cutaneous (10%), venom (n=3), drug (7%), and food hypersensitivity (n=2). Multiple allergic diseases were detected in 20%. Eighty-six % (n=138) could recognize the culprit drug. The causes of drug allergy were non-steroidal anti-inflammatory drugs (NSAIDs) (27%), beta-lactams (16%), co-sensitization to beta-lactams and NSAIDs (8%), antimicrobials except beta-lactams (8%), and other kinds of drugs (39%). Type 1 reaction occurred in 80%, type 4 in 21%, non-immune mediated in 7, and mixed type composed of type 1 and 4 in 9 patients. Anaphylaxis occurred in 46,5%. Fifteen% had grade 2, 22% had grade 3, and 4 had grade 4 anaphylactic reactions. According to systematical assessment, cutaneous symptoms were observed in 93%, respiratory in 38%, cardiovascular in 29,5%, neurologic in 25%, and gastrointestinal in 11%. Allergy to NSAIDs (88,6 %) and beta-lactams (82,5%) were more frequent in type 1 reactions than in type 4 and mixed type reactions (p

Published: September 2023

Purpose: The aim of this study is to determine the attitudes of nulliparous women toward fertility and childbirth.
Material and Method: The research was carried out as a cross-sectional descriptive method with improbable sampling technique. Recruitment for participation in the study took place with power analysis and consisted of 213 nulliparous women who had never been pregnant before. Data were collected with the Personal Information Form and the Attitudes Toward Fertility and Childbearing Scale.
Findings: 54% of the women are between the ages of 19-26 and the mean age is 26.51±5.19. It was determined that 76.5% of the women were married for 1-3 years and 65.7% of them used contraception. The total score of the Attitudes Towards Fertility and Childbearing Scale is 69.54±8.28, and the mean subscale score current obstacle 21.57±7.08; importance in the future 28.42±4.63; female identity is 19.55±3.82. It has been determined that women have a positive attitude to fertility and childbearing. In comparison with the total score of the scale and the variables, it was determined that there was a significant difference between variables of age, occupation status, spouse's age, spouse's occupation status, spouse's smoking status, consanguineous marriage, family type, financial status, spouse's age at marriage and mean value of total scale score.
Result: The fact that nulliparous women's attitudes to fertility and childbearing are affected by many factors such as age, occupation status, spouse's age shows that there are many variables that should be considered during the evaluation of nulliparous women by midwives. It is very important for pregnancy planning that women in the preconceptional period have positive attitudes to fertility and childbearing.

ImportanceHypernatremia is common among hospitalized patients and is associated with high mortality rates. Current guidelines suggest avoiding fast correction rates but are not supported by robust data.ObjectiveTo investigate whether there is an association between hypernatremia correction rate and patient survival.Design, Setting, and ParticipantsThis retrospective cohort study examined data from all patients admitted to the Tel Aviv Medical Center between 2007 and 2021 who were diagnosed with severe hypernatremia (serum sodium ≥155 mmol/L) at admission or during hospitalization. Statistical analysis was performed from April 2022 to August 2023.ExposurePatients were grouped as having fast correction rates (&amp;gt;0.5 mmol/L/h) and slow correction rates (≤0.5 mmol/L/h) in accordance with current guidelines.Main Outcomes and MeasuresAll-cause 30-day mortality.ResultsA total of 4265 patients were included in this cohort, of which 2621 (61.5%) were men and 343 (8.0%) had fast correction rates; the median (IQR) age at diagnosis was 78 (64-87) years. Slow correction was associated with higher 30-day mortality compared with fast correction (50.7% [1990 of 3922] vs 31.8% [109 of 343]; P &amp;lt; .001). These results remained significant after adjusting for demographics (age, gender), Charlson comorbidity index, initial sodium, potassium, and creatinine levels, hospitalization in an ICU, and severe hyperglycemia (adjusted odds ratio [aOR], 2.02 [95% CI, 1.55-2.62]), regardless of whether hypernatremia was hospital acquired (aOR, 2.19 [95% CI, 1.57-3.05]) or documented on admission (aOR, 1.64 [95% CI, 1.06-2.55]). There was a strong negative correlation between absolute sodium correction during the first 24 hours following the initial documentation of severe hypernatremia and 30-day mortality (Pearson correlation coefficient, −0.80 [95% CI, −0.93 to −0.50]; P &amp;lt; .001). Median (IQR) hospitalization length was shorter for fast correction vs slow correction rates (5.0 [2.1-14.9] days vs 7.2 [3.5-16.1] days; P &amp;lt; .001). Prevalence of neurological complications was comparable for both groups, and none were attributed to fast correction rates of hypernatremia.Conclusions and RelevanceThis cohort study of patients with severe hypernatremia found that rapid correction of hypernatremia was associated with shorter hospitalizations and significantly lower patient mortality without any signs of neurologic complications. These results suggest that physicians should consider the totality of evidence when considering the optimal rates of correction for patients with severe hypernatremia.

Published: September 2023

A breakthrough study from Du et al. has developed a wearable, ultrasound imaging patch for standardized and reproducible breast tissue imaging. The technology utilizes a honeycomb patch design to facilitate guided movement of the ultrasound array, enabling comprehensive, multiangle breast imaging. The system was validated in vitro and in vivo with a single human subject and has the potential for early‐stage breast cancer detection. This study addressed the current limitations of wearable ultrasound technologies, including imaging over large, curvilinear organs and integration of superior piezoelectric materials for high‐performance ultrasound arrays. The transition of ultrasound from the bedside to portable and wearable devices will pave the way for integration with big data collection, such as artificial intelligence (AI)‐based diagnosis and personalized ultrasonographic profile generation, for rapid and objective measurements. This advancement is especially important in the context of breast cancer, where early diagnosis and assessment of medical therapy responses are paramount to patient care.

Published: September 2023

AbstractPolymer dielectrics capable of operating stably at high temperatures (>150 °C) are urgently in great demand to catch up with the booming electric power systems. Enhancing the heat resistance of polymers is typically achieved through thermal crosslinking with the use of crosslinking agents. Unfortunately, the conventional thermal crosslinking faces challenges in terms of commercialization due to its complex fabrication, inevitable introduction of small molecule impurities, and significant time and energy consumption. Here, a convenient, impurity‐free, time and energy efficient photo‐crosslinking method to create wide bandgap heterostructures within a dielectric polymer matrix, is presented. Remarkably, this approach achieves synergistically enhanced heat resistance and electrical insulation. Surprisingly, the crosslinked polymer exhibits an unprecedented Weibull characteristic breakdown strength of 1057 and 810 MV m−1 at room temperature and at 150 °C, respectively, which corresponds to superior energy storage densities of 14.28 and 5.55 J cm−3 with a charge–discharge efficiency of 90%, respectively. Furthermore, the polymer demonstrates an excellent electrical breakdown self‐healing character. These remarkable achievements, combined with the convenient and cost‐effective fabrication process, highlight the potential of cinnamate photo‐crosslinking in advancing high‐performance polymer dielectrics.

AbstractOsmotic energy represents a promising energy resource because it is sustainable and environmentally benign. Subnanoscale channels are considered as a competitive platform for generating this blue energy due to their highly selective and ultrafast ion transport. However, fabricating functional subnanochannels capable of high energy output remains challenging. Here, a heterogeneous subnanochannel membrane formed by coating a functionalized self‐assembled metal−organic framework (MOF) monolayer (SAMM) film on a porous anodic aluminum oxide membrane, is reported. The SAMM film, with a thickness of ≈160 nm, is fabricated by self‐assembly of poly(methyl methacrylate‐co‐vinylimidazole)‐modified UiO‐66‐NH2 nanoparticles at the water−air interface. In the SAMM, imidazole and NH2 groups provide abundant positive charges, while the angstrom‐scale windows act as ionic filters for selective screening of anions with different hydration diameters. As a result, the heterogeneous membrane exhibits excellent capacity for anion‐selective transport, which contributes to an optimal osmotic power of 6.76 W m−2 under a 100‐fold NaCl gradient, as well as a high Cl−/SO42− selectivity of ≈42.2. Further, the output power is increased to 10.5 W m−2 by methylating imidazole moieties on the MOF surface. This work provides a facile and modular approach to fabricate subnanochannels for enabling highly selective and efficient osmotic energy conversion.

AbstractIntroducing nanostructures into bulk thermoelectric materials is an effective strategy for reducing lattice thermal conductivity (κlat). However, large numbers of hanging bonds emerge on account of lattice mismatch usually at the interfaces between nanostructures and matrix, thereby significantly deteriorating carrier mobility (µH) and seriously limiting thermoelectric performance. Here, utilizing the cointroduction of Gd‐Cu2Te into n‐type PbSe as a paradigm, the zT could be greatly improved. The conduction band flattening caused by Gd doping can successfully compensate for the small Seebeck coefficient in n‐type PbSe, thus achieving extraordinary electrical performance. Further advanced electron microscopy and X‐ray absorption fine structure spectra directly demonstrate that most of the Cu forms nanoscale Cu2Se precipitates, especially a unique semi‐coherent interface between the PbSe matrix and the Cu2Se nanoprecipitate is observed for the first time. Such nanoprecipitate accompanied by the semi‐coherent interface not only ensures higher µH as an excellent charge transfer mediator but also collectively scatters the heat‐carrying phonons over a wide frequency range to obtain the ultralow κlat, resulting in the prominent improvement of the ratio µH/κlat. The present finding represents an important step forward in electron–phonon decoupling via constructing semi‐coherent nanostructure and interface engineering, which should be applicable for other thermoelectric materials.

AbstractWith 40% efficiency under room light intensity, perovskite solar cells (PSCs) will be promising power supplies for low‐light applications, particularly for Internet of Things (IoT) devices and indoor electronics, shall they become commercialized. Herein, β‐alaninamide hydrochloride (AHC) is utilized to spontaneously form a layer of 2D perovskite nucleation seeds for improved film uniformity, crystallization quality, and solar cell performance. It is found that the AHC addition indeed improves film quality as demonstrated by better uniformity, lower trap density, smaller lattice stress, and, as a result, a 10‐fold increase in charge carrier lifetime. Consequently, not only does the small‐area (0.09 cm2) PSCs achieve a power conversion efficiency of 42.12%, the large‐area cells (1.00 cm2, and 2.56 cm2) attain efficiency as high as 40.93%, and 40.07% respectively. All of these are the highest efficiency values for indoor photovoltaic cells with similar sizes, and more importantly, they represent the smallest efficiency loss due to area scale‐up. This work provides a new method to fabricate high‐performance indoor PSCs (i‐PSCs) for IoT devices with great potential in large‐area printing technology.

AbstractThe preparation of highly conductive media and the construction of conducting channels play a crucial role in improving the electrical conductivity of electrically conductive adhesives. Therefore, a new MXene structure is reported in this paper, and the improved structure is rationally designed by computational modeling, which greatly prevents the buildup of MXene nanosheets, improves the stability of the structure, and creates a wide electron transfer channel, and the capacitance contribution of this structure is up to 86.3%. By mixing MXene modified with Ag‐plated copper powder in a quantitative relationship to form high conductive media, the electrical conductivity is largely improved and the defect of low electron transfer rate of conventional conductive fillers is broken. The potential value of high conductive media is largely exploited using high throughput and machine learning methods, and here we show that the resistivity has reached 9.668 × 10−7 Ω m. The first principles investigate the conductive channels and electron transfer pathways of high‐conductive media at the atomic level, further revealing the mechanism of action of high‐conductive media. This study is also the first report on the application of MXene to high‐conductive media.

AbstractLayered oxides represent a prominent class of cathodes employed in lithium‐ion batteries. The structural degradation of layered cathodes causes capacity decay during cycling, which is generally induced by anisotropic lattice strain in the bulk of cathode particle and oxygen release at the surface. However, particularly in lithium‐rich layered oxides (LLOs) that undergo intense oxygen redox reactions, the challenge of simultaneously addressing bulk and surface issues through a singular modification technique remains arduous. Here a thin (1‐nm) and coherent spinel‐like phase is constructed on the surface of LLOs particle to suppress bulk strain and surface O2 release by just adjusting the amount of lithium source during synthesis. The spinel‐like phase hinders the surface O2 release by accommodating O2 inside the surface layer, while the trapped O2 in the bulk impedes strain evolution by ≈70% at high voltages compared with unmodified LLOs. Consequently, the enhanced structural stability leads to an improved capacity retention of 97.6% and a high Coulombic efficiency of ≈99.5% after 100 cycles at 0.1°C. These findings provide profound mechanistic insights into the functioning of surface structure and offer guidance for synthesizing high‐capacity cathodes with superior cyclability.

AbstractUltrahigh‐contrast photodetection with low background noise is of critical importance for accurate image‐sensing in deep‐sea and deep‐space exploration. The state‐of‐the‐art silicon and III–V semiconductor‐based photodetectors usually require extended exposure to incident light for high‐quality sensing in darkness, which unfortunately results in large room temperature dark currents (RT‐Idark) and deteriorates the expected imaging contrasts. Herein, a high‐performance violet phosphorus (VP) phototransistor is reported by constructing a trap‐free interface between the VP channel and hexagonal boron nitride (h‐BN) dielectric via perfect van der Waals stacking. The device shows an extremely low RT‐Idark of 80 fA and gate‐tunable high ON/OFF ratio over 105, which is 2–4 orders of magnitude superior to that of conventional counterparts. A VP photodetector array has been fabricated to demonstrate the high‐contrast image‐sensing capability. The findings demonstrate the effectiveness of VP in low background noise and ultrahigh‐contrast image‐sensing applications, while also presenting exciting opportunities to enhance interface qualities through van der Waals architectures for high‐performance optoelectronics.

AbstractThe inhomogeneous native oxide shells on the surfaces of III–V group semiconductors typically yield inferior and unstable electrical properties metrics, challenging the development of next‐generation integrated circuits. Herein, the native GaOx shells are profitably utilized by a simple in‐situ thermal annealing process to achieve high‐performance GaSb nanowires (NWs) field‐effect‐transistors (FETs) with excellent bias‐stress stability and synaptic behaviors. By an optimal annealing time of 5 min, the as‐constructed GaSb NW FET demonstrates excellent stability with a minimal shift of transfer curve (ΔVth ≈ 0.54 V) under a 60 min gate bias, which is far more stable than that of pristine GaSb NW FET (ΔVth ≈ 8.2 V). When the high bias‐stress stability NW FET is used as the chargeable‐dielectric free synaptic transistor, the typical synaptic behaviors, such as short‐term plasticity, long‐term plasticity, spike‐time‐dependent plasticity, and reliable learning stability are demonstrated successfully through the voltage tests. The mobile oxygen ion in the native GaOx shell strongly offsets the trapping states and leads to enhanced bias‐stress stability and charge retention capability for synaptic behaviors. This work provides a new way of utilizing the native oxide shell to realize stable FET for chargeable‐dielectric free neuromorphic computing systems.
