Abi  is one of the villages with the lowest percentage of healthy latrines ownership compared to other  in Oenino Subdistrict.There are 46 household (18,5%) that have access to healthy latrines in Abi village. The purpose of this study was to analyze what factors influence the ownership of healthy latrines  in Abi Village Oenino District of Timor Tengah Selatan. This study is an observational study using a cross sectional design, as more as 78 respondents taken with simple random sampling techniques. Independent variables studied (knowledge, attitudes, socioeconomic level, clean water adequacy, role of village governments, and the role of health officers) and dependent variables (healthy latrines ownership). The collected data would be analyzed chi-square test. The results showed that 51,3%   low public knowledge, 51,3% had a negative public attitude,69,2%  low socio-economic level of society, 56,4% of clean water need were not fulfilled, 39,7 did not receive support from the village government, 53,8% did not receive support from health workers. There is a relationship between knowledge  and the ownership of healthy latrines (p =0.007), attitude (p=0.002), sosioeconomic level (p=0.002), the adequacy of clean water (p=0.000), the Role of Village Government, (p=0.026), The Role of Health officers (p=0.011). The low ownership of healthy latrines in Abi village is influenced by factors of low socioeconomic level and   adequacy of water needs because clean water sources are far away and limited clean water reservoirs.

Published: September 2022

Instalasi Rawat Jalan merupakan unit fungsional yang menangani penerimaan pasien yang berobat rawat jalan di rumah sakit. RSUD Kota Semarang berpotensi menjadi rumah sakit rujukan utama bagi masyarakat Kota Semarang. Salah satu harapan pasien adalah tidak perlu menunggu lama untuk mendapatkan pelayanan, tetapi masih ada pernyataan pasien yang sedang menunggu pelayanan pendaftaran bahwa antriannya masih terlalu lama. Tujuan penelitian adalah menganalisis sistem antrian di loket pendaftaran pasien rawat jalan RSUD Kota Semarang. Jenis Penelitian yang dilakukan merupakan metode penelitian deskriptif dengan pendekatan studi pontong lintang. Data tingkat kedatangan dan waktu pelayanan setiap pasien diperoleh dari loket pendaftaran pasien rawat jalan selama satu minggu (Senin-Sabtu). Model antrian pendaftaran rawat jalan RSUD Kota semarang menggunakan sistem M/M/1, yaitu proses antrian dengan 1 petugas pelayanan di setiap jenis pembiayaan dan FIFO sebagai disiplin antrian. Angka kedatangan tertinggi di masing-masing jenis pembiayaan pada jam buka pengambilan nomor antrian yaitu jam 06.30-07.29. Rata-rata waktu pelayanan pendaftaran loket rawat jalan pada pasien askes 1,3 menit, pada pasien jamkesmas 0,98 menit dan pada pasien umum 1,6 menit. Rata-rata waktu tunggu pelayanan pendaftaran rawat jalan RSUD Kota Semarang pada pasien askes dan pasiem umum terlama terjadi pada jam pelayanan 07.30-08.29 dan tercepat pada jam pelayanan 11.30-12.00, sedangkan pada pasien jamkesmas waktu tunggu pelayanan terlama pada jam pelayanan 08.30-09.29 dan tercepat pada jam pelayanan 11.30-12.00. Untuk menghindari antrian panjang yang terjadi di semua jenis pembiayaan, perlu adanya penambahan loket sehingga dapat mengurangi panjang antrian, meskipun penambahan loket akan mempengaruhi penambahan tenaga dan peralatan yang ada, hal ini juga dapat dijadikan dasar untuk mengurangi lama waktu tunggu.
The Influence of Various Substrates on Power Generation in The Operation of Yeast Microbial Fuel Cells
Authors: Christwardana Marcelinus , Joelianingsih J. , Yoshi Linda Aliffia
Published: September 2022

Several carbon substrates were tried, including glucose commercial, pro analysis glucose, commercial sugar, and yeast extract - peptone - d glucose (YPD) medium to improve the efficiency of the single chamber microbial fuel cell (MFC). The power production of various electron donors was investigated using baker yeast Saccharomyces cerevisiae. Voltage and power density generation were used to establish the pattern of substrate use. In addition, electrochemical analysis of the anodic biofilm was performed. S. cervisiae was shown to successfully consume YPD medium by anode respiration with a higher power density of 18.40±1.98 mW/m2, followed by pro analysis glucose (9.41±1.15 mW/m2), commercial glucose (1.30±0.10 mW/m2), and commercial sugar (0.04±0.01 mW/m2). Furthermore, a clear relationship was established between power density generating rate and voltage output. Voltages produced were 0.16±0.02 V, 0.13±0.03 V, 0.03±0.01 V, 0.01±0.00 V for YPD medium, pro analysis glucose, commercial glucose, and commercial sugar, respectively in MFC. The weight of biofilm indicated that yeast attachment was significantly more common in YPD medium than in other MFC-operated media. This study discovered that the substrate type in the anodic compartment regulates the formation of anodic biofilm.

Pressure sensor catheter based on Fiber Tip Fabry-Pérot-Interferometer and Fiber Bragg Grating for temperature compensation
Authors: Friedemann Marvin , Voigt Sebastian , Mehner Jan
Published: September 2022

This paper introduces a pressure sensor catheter with two different measurement principles. A Fabry-Perot- Interferometer at the fiber tip is formed by a reflective multilayer membrane of a pressure sensor chip. The cavity provides absolute pressure sensing. 20 millimeter before the fiber tip a Fiber Bragg Grating is integrated for additional temperature sensing. The sensing components are completely coated with a silicone mantle of 2 mm diameter. The signal evaluation is both done with a Fiber Bragg Grating interrogation device. First, mechanical structure aspects of the manufactured fiber-optic hybrid sensor as well as the sensing principle is described. Then, experimental results, including quantification and separation of pressure and temperature sensitivity are presented. Out of these characteristics the possibility for absolute pressure sensing with temperature compensation for the application as a pressure sensor catheter is confirmed.
Stratification of singular hyperkähler quotients
Authors: Mayrand Maxence
Published: September 2022

Hyperkähler quotients by non-free actions are typically singular, but are nevertheless partitioned into smooth hyperkähler manifolds. We show that these partitions are topological stratifications, in a strong sense. We also endow the quotients with global Poisson structures which recover the hyperkähler structures on the strata. Finally, we give a local model which shows that these quotients are locally isomorphic to linear complex-symplectic reductions in the GIT sense. These results can be thought of as the hyperkähler analogues of Sjamaar–Lerman’s theorems for singular symplectic reduction. They are based on a local normal form for the underlying complex-Hamiltonian manifold, which may be of independent interest.

Authors: Shi Xuejun , Wei Baoting , Han Yongjun , Du Xiangxiang , He Guoxu
Published: September 2022

Silicon carbide (SiC) was modified by melamine polyphosphate (MPP)-modified silicone to form SiC-MPP, then incorporated into epoxy resin (EP) for developing thermally resistant composites, which showed thermal conductivity and flame retardancy performance. The EP/SiC-MPP composites were prepared by blending and cured under 60°C for 2 h and 150°C for 8 h. The grafting degree of SiC-MPP was analyzed using Fourier transform Infrared, scanning electron microscope, and thermogravimetric measurements. The flame retardancy of the EP/SiC-MPP composites was studied by UL-94 vertical combustion and cone calorimetry test. The results showed that for EP/SiC-MPP containing 20 wt%, the UL-94 was case V1. Also compared to pure epoxy, the peak heat release rate (PHRR) of composites was reduced from 800 to 304 kW·m−2. The thermal conductivity of EP/SiC-M20 composites was 0.53 W·m−1·K−1, almost 2.5-fold higher than pure epoxy (0.21 W·m−1·K−1). The as-prepared EP/SiC-MPP composites exhibited enhanced flame retardancy and thermal conductivity. Based on analyses performed, these composites took credit-related applications.
Recovery of cobalt from spent lithium-ion battery cathode materials by using choline chloride-based deep eutectic solvent
Authors: Yu Honghao , Wang Shaomian , Li Yin , Qiao Qian , Wang Kun , Li Xin
Published: September 2022

Recycling of spent lithium (Li)-ion batteries has become a hot research topic due to its surge in the quantity and environmental problems. Herein we demonstrated a new chemical configuration of choline chloride-based deep eutectic solvent (DES) to recover the cobalt from lithium cobalt oxide (LiCoO2), a representative cathode material for Li-ion battery. It was experimentally verified that the leaching efficiency of Co increased rapidly with the increase in the reaction temperature. Nearly 96% of Co can be leached from lithium cobalt oxide after a leaching treatment at 200℃ for 20 h. The leaching mechanism of cobalt in DES was analyzed by using a variety of techniques, including cyclic voltammetric experiments, Fourier transform infrared radiation, and ultraviolet-visible spectra. The results showed that the LiCoO2 dissolve into the DES via reduction of Co(iii) to Co(ii). In particular to this work, the leaching experiments were performed in a higher concentration than those in the previous studies, which significantly promoted the operating efficiency of the leaching process.
The effect of the ratio of serum progesterone level to oocyte count on the day of IVF-ICSI injection on pregnancy outcomes in HCG cycles
Authors: Khahani Namin Azita , Mohammadian Farnaz , Garrosi Lida , Tofighi Shabnam
Published: September 2022

Background

There has been several discussion and debates regarding the possible setremental influence of elevated serum progesterone (SP) on the day of human chorionic gonadotropin (hCG) administration. Our study aims to assess progestron to oocyte rates for assessing CPR and live birth rate (LBR) in IVF cycles and review previous articles.

Methods

In this prospective cohort study, women under ovulation induction through IVF-ICSI using the GnRH-antagonist protocol were studied. Five specific indicators were considered to assess pregnancy outcome. The statistical analysis was done using SPSS software.

Results

In the present research, 78 patients underwent IVF. The cut-off points for each of the three parameters were 1.2 (with a sensitivity of 65.4% and a specificity of 54%), 6.5 (with a sensitivity of 73.1% and a specificity of 56%), and 0.16 (with a sensitivity of 65.4% and a specificity of 60%, respectively). Only the number of oocytes (area below the curve of 0.64) was able to predict clinical pregnancy. The cut-off point for this parameter was 6.5 (with a sensitivity of 74.1% and a specificity of 66%). On the other hand, none of the parameters were able to predict live birth.

Conclusions

The findings of this study should assist in the clinical management of patients with high SP on the day of HCG administration. We recommend, that the ratio of SP to oocyte is a useful parameter for refining the criteria of patients who have had embryo freezing of all embryos (by selective freezing) and subsequent transfer of frozen embryos.
Immersive analytics: An overview
Authors: Klein Karsten , Sedlmair Michael , Schreiber Falk
Published: September 2022

Immersive Analytics is concerned with the systematic examination of the benefits and challenges of using immersive environments for data analysis, and the development of corresponding designs that improve the quality and efficiency of the analysis process. While immersive technologies are now broadly available, practical solutions haven’t received broad acceptance in real-world applications outside of several core areas, and proper guidelines on the design of such solutions are still under development. Both fundamental research and applications bring together topics and questions from several fields, and open a wide range of directions regarding underlying theory, evidence from user studies, and practical solutions tailored towards the requirements of application areas. We give an overview on the concepts, topics, research questions, and challenges.
Performance of glucagon stimulation test in diagnosing central adrenal insufficiency in children when utilising the Roche Elecsys® cortisol II assay: a pilot study
Authors: Zöllner Ekkehard Werner , Lombard Carl J. , Zemlin Annalise E.
Published: September 2022

Objectives

The glucagon stimulation test (GST) is used for the simultaneous assessment of central adrenal insufficiency (CAI) and growth hormone deficiency. The new Roche cortisol II (C II) assay was recently introduced, confounding interpretation of the GST. The performance of the GST in diagnosing central adrenal insufficiency (CAI), utilising the C II assay, was therefore compared with that of the overnight metyrapone test (ONMTPT).

Methods

A diagnostic accuracy study was performed by retrospectively analysing folders and laboratory records of 25 children and adolescents investigated for hypopituitarism with the GST and the ONMTPT between September 2016 and December 2019. The peak serum cortisol (C) of the GST, the post-metyrapone serum 11-deoxycortisol and adrenocorticotropin levels of the ONMTPT were recorded. Diagnostic performance of the GST at a previously suggested cut-off of 374 nmol/L was evaluated.

Results

Seventeen boys and 8 girls, aged 1.7–16.3 years (median 7.3 years) were identified. The sensitivity of the post-GST C-level at 374 nmol/L was 0.40 (95% confidence interval [CI] 0.17–0.69), specificity 0.64 (95% CI 0.39–0.84), positive predictive value 0.44 (95% CI 0.19–0.73), negative predictive value 0.60 (95% CI 0.36–0.80), accuracy 0.54 (95% CI 0.35–0.72), positive likelihood ratio (+LR) 0.93 (95% CI 0.49–1.77) and negative LR 1.12 (95% CI 0.40–3.15). The area under the receiver of operating characteristics (ROC) curve was 0.379 (95% CI 0.142–0.615).

Conclusions

This study suggests that the GST at any C II cut-off cannot replace the ONMTPT as a diagnostic test for CAI in children. Findings should be confirmed in a larger study.

Authors: Loomba Lindsey A. , Hughes Lansing Amy , Cortez Justine N. , Welch Kearnan , Solowiejczyk Joe N. , Ghetti Simona , Styne Dennis M. , Glaser Nicole S.
Published: September 2022

Objectives

Glycemic outcomes in children with type 1 diabetes (T1D) vary widely, despite uniform care. We hypothesized that glycemic outcomes in children with T1D are affected by the marital relationship satisfaction of the child’s parents.

Methods

We evaluated a prospective sample of 51 families with a child with newly diagnosed T1D, including 36 married parent families. We assessed indicators of marital relationship satisfaction and used multiple regression models to determine whether marital relationship satisfaction at diagnosis was associated with mean HbA1c 18–24 months after diagnosis.

Results

Marital status and parental relationship satisfaction at the time of the child’s T1D diagnosis were associated with HbA1c 18–24 months later. These differences persisted after adjusting for demographic factors associated with glycemia.

Conclusions

The quality of the primary diabetes caregiver’s relationship with a spouse predicts glycemic outcomes for children with T1D. Interventions to improve spousal relationships and caregiver support could improve glycemic control in children with T1D.

The purpose of this study was to analyze international graduate students’ study abroad experiences at a university in Japan. In this qualitative study, in-depth, semi-structured interviews (Seidman, I. (1998). Interviewing as qualitative research: A guide for researchers in education and the social sciences (2nd ed.). Teacher College Press) grounded in the concept of the sojourner (Siu, P. C. P. (1952). The sojourner. American Journal of Sociology, 58, 34–44) were conducted with international students studying in an English-medium graduate program at a university located in the Kanto region of Japan. The five participants, ranging from 25 to 42 years of age, were from Nigeria, India, Peru, and the United States and were enrolled in a master’s program in physical education, health and sport sciences. Three recurrent themes were identified: (a) challenges in overcoming loneliness on campus, (b) importance of participation in extracurricular activities (on and off campus), and (c) language barriers and cultural differences in daily living. To better support international graduate students at Japanese universities, we encourage faculty, international education office staff, and all students to respect, value, and embrace the languages and cultures of international students.
Diffractive interconnects: all-optical permutation operation using diffractive networks
Authors: Mengu Deniz , Zhao Yifan , Tabassum Anika , Jarrahi Mona , Ozcan Aydogan
Published: September 2022

Permutation matrices form an important computational building block frequently used in various fields including, e.g., communications, information security, and data processing. Optical implementation of permutation operators with relatively large number of input–output interconnections based on power-efficient, fast, and compact platforms is highly desirable. Here, we present diffractive optical networks engineered through deep learning to all-optically perform permutation operations that can scale to hundreds of thousands of interconnections between an input and an output field-of-view using passive transmissive layers that are individually structured at the wavelength scale. Our findings indicate that the capacity of the diffractive optical network in approximating a given permutation operation increases proportional to the number of diffractive layers and trainable transmission elements in the system. Such deeper diffractive network designs can pose practical challenges in terms of physical alignment and output diffraction efficiency of the system. We addressed these challenges by designing misalignment tolerant diffractive designs that can all-optically perform arbitrarily selected permutation operations, and experimentally demonstrated, for the first time, a diffractive permutation network that operates at THz part of the spectrum. Diffractive permutation networks might find various applications in, e.g., security, image encryption, and data processing, along with telecommunications; especially with the carrier frequencies in wireless communications approaching THz-bands, the presented diffractive permutation networks can potentially serve as channel routing and interconnection panels in wireless networks.

The increase in biodiesel production has resulted in the oversupply of glycerol into the market. Purified and processed glycerol has found many direct applications in pharmaceuticals, food, etc. However, the cost of processing and market value of processed glycerol has driven the research of direct utilization of crude glycerol to industrially essential chemicals. Various methods and research have been devoted to using glycerol to produce value-added products separately. Glycerol can undergo several transformation reactions like hydrogenation, oxidation, alcoholysis, and etherification. Etherification of glycerol can be divided into three main reactions: self-etherification, using alcohol, and olefins and these products have vast applications such as fuel additives, plasticizer, etc. The current review presents a comprehensive summary of glycerol etherification to value-added products and their applications. The catalytic system developed along with reaction conditions and the factors responsible for the better activity is also discussed. Overall, the review presents a detailed discussion on the catalytic system developed, the utilization of different alcohols and olefins, and the application of products. Moreover, the environmental and economic aspects of the etherification of glycerol via various conversion routes while assessing the process parameters needs to be tackled to attain wider adoption of the process.
Revisiting gender-fair language and stereotypes – A comparison of word pairs, capital I forms and the asterisk
Authors: Schunack Silke , Binanzer Anja
Published: September 2022

In this paper we replicated two influential studies on gender-fair language that investigated how gender-fair language influences stereotype perception and recall of exemplars. We also updated the original studies to assess new forms of gender-fair language. A first set of studies replicated Gabriel et al. (2008) by eliciting gender proportion ratings for occupational nouns from adult German native speakers for word pairs, capital I forms and the asterisk. Results were mixed with effects mainly for female-biased nouns. Only the non-binary asterisk form (Lehrer*innen) showed an increase of women for male-biased nouns. A third study replicated Stahlberg and Sczesny’s (2001) naming study. Here, the number of women answers was higher than in the original study and increased when using gender-fair language with a larger increase for capital I forms (LehrerInnen) than for word pairs (Lehrer und Lehrerinnen). Overall, the effects of word pair forms were weaker than those of other forms of gender-fair language.
Revisiting the structure of (±)-[Co(en)3]I3·H2O – X-ray crystallographic and second-Harmonic results
Authors: Sohail Khurshid , Lalancette Roger A. , Bernal Ivan , Guo Xiaoyu , Zhao Liuyan
Published: September 2022

As described in the Introduction, we became interested in the existing literature for the crystallization behavior of (±)-[Co(en)3]I3·H2O and the absolute configuration of its enantiomers because of our project on the historical sequence of chemical studies leading Werner to formulate his Theory of Coordination Chemistry. In so doing, we discovered a number of interesting facts, including the possibility that the published “Pbca” structure of the (±)-[Co(en)3]I3·H2O was incorrect, and that it really crystallizes as a kryptoracemate in space group P212121. Other equally interesting facts concerning the crystallization behavior of [Co(en)3]I3·H2O are detailed below, together with an explanation why Platon incorrectly selects, in this case, the space group Pbca instead of the correct choice, P212121. As for the Flack parameter, (±)-[Co(en)3]I3·H2O provides an example long sought by Flack himself – a challenging case, differing from the norm. For that purpose, data sets (for the pure enantiomer and for the racemate) were collected at 100 K with R-factors of 4.24 and 2.82%, respectively, which are ideal for such a test. The fact that Pbca is unacceptable in this case is documented by the results of Second-Harmonic Generation experiments. CCDC nos: 1562401 for compound (I) and 1562403 for compound (II).

The implementation of high-throughput and deep sequencing methods in routine genetic diagnostics has significantly improved the diagnostic yield in patient cohorts with growth disturbances and becomes increasingly important as the prerequisite of personalized medicine. They provide considerable chances to identify even rare and unexpected situations; nevertheless, we must be aware of their limitations. A simple genetic test in the beginning of a testing cascade might also help to identify the genetic cause of specific growth disorders. However, the clinical picture of genetically caused growth disturbance phenotypes can vary widely, and there is a broad clinical overlap between different growth disturbance disorders. As a consequence, the clinical diagnosis and therewith connected the decision on the appropriate genetic test is often a challenge. In fact, the clinician asking for genetic testing has to weigh different aspects in this decision process, including appropriateness (single gene test, stepwise procedure, comprehensive testing), turnaround time as the basis for rapid intervention, and economic considerations. Therefore, a frequent question in that context is ‘what to test when’. In this review, we aim to review genetic testing strategies and their strengths and limitations and to raise awareness for the future implementation of interdisciplinary genome medicine in diagnoses, treatment, and counselling of growth disturbances.

The article analyzes the current situation and debates about the digital currencies issued by central bank. The results show that only a few countries have issued the central bank digital currencies, the rest of the countries have begun to have institutional orientations for research on issuing and using the central bank digital currency. The strengths that lead to the central bank's choice of research and issuance of digital currency are a high level of security, convenience for money control in circulation, and the stable value guaranteed by the state, thereby contributing to the promotion of non-cash payments. In the context of accelerating the economy digitization, including digital banking, and promoting the cash payments, Vietnam has had an orientation to research mechanisms, policies and laws for the issuance of national digital currency. In order to do this, in addition to reviewing, amending and supplementing the Law on the State Bank of Vietnam related to currency issuance, it is also necessary to prepare fully the technical infrastructure system.

The coronavirus pandemic has spread globally and resulted in the registered deaths of over 5.5 million people, with nearly 380 million infected, straining health systems focused on transmission suppression and supportive care because specific treatment options are limited. COVID-19 is a microvascular disease with dominant respiratory representation, but a significant number of patients experience multisystem or extrarespiratory organ involvement. Although severe acute respiratory syndrome coronavirus-2 has some degree of a direct cytopathic effect on cardiomyocytes, the oxidative burst on a microvascular level seems to be the key for both short- and long-term adverse health effects. Targeted diagnostics and treatment without substantial delay may reduce the amplified immune response; otherwise, considerable tissue damage may occur with unfavourable consequences, including acute and chronic cardiac syndromes. This paper reviews the pathomechanisms relevant to the short- and long-term cardiac effects of COVID-19. Data were identified by searching the PubMed database and reviewing references from relevant articles published in English; abstracts and meeting reports were excluded.
Contribuciones de la distribución de la tierra al desarrollo de los países. Una revisión de la literatura
Authors: Anaya Campo Alexander De Jesús
Published: September 2022

La redistribución de la tierra favoreció el crecimiento económico de China, Corea del Sur, Japón y Taiwán. En estos países, la distribución, aunada al apoyo estatal, contribuyó en buena medida a la subsecuente industrialización de sus economías. La literatura reconoce el notable desarrollo del Este Asiático. Sin embargo, en otras naciones, especialmente de África y Latinoamérica, las reformas agrarias distributivas no evidencian resultados satisfactorios en materia de desarrollo. Este artículo revisa la literatura sobre las contribuciones de la distribución de la tierra al desarrollo de algunos países que padecieron o padecen alta concentración de tierra y problemas de pobreza.

Devido à alta taxa de jovens envolvidos em acidentes de trânsito, o objetivo deste estudo foi avaliar as relações entre estilos parentais, impulsividade e comportamentos de direção em uma amostra de 292 jovens adultos. Os dados foram coletados por meio do Inventário de Estilos Parentais, do Questionário do Comportamento do motorista e da Escala de Impulsividade de Barrat. Os resultados mostraram uma correlação negativa (p < 0,01) entre estilos maternos positivos com o comportamento de risco no trânsito e uma correlação positiva (p < 0,01) entre impulsividade e comportamento de risco, de forma que o baixo controle inibitório apresentou interação com práticas parentais negativas e associação significativa (p = 0,04) com erros, lapsos e violações no trânsito. Os modelos de regressão linear múltipla apontaram que os estilos parentais e a impulsividade são preditores do comportamento de risco do motorista.
Narrando normativas escolares

Este artigo tem como objetivo investigar quais as possíveis condições de emergência das demandas por diagnósticos psiquiátricos advindas das escolas atuais, em destaque, as escolas públicas brasileiras. A investigação teve início contrapondo diferentes modelos de escola ao longo do tempo, demonstrando como cada um destes produziu em sua conjuntura, um modelo norma-desvio que fundamenta a prática escolar. Ao longo da discussão, a dimensão diagnóstica emergiu atrelada à crescente sistematização avaliativa das escolas, corroborando com a dimensão neoliberal de uma escola que busca alcançar lucros. Em uma problematização teórica que dialoga com os estudos foucaultianos, pode-se demonstrar o quanto a emergência por diagnósticos psiquiátricos faz parte da atual racionalidade governamental da instituição escola. Nas conclusões, a questão referente ao diagnóstico psiquiátrico apresenta-se como uma modulação da diferença, cuja demanda crescente no contexto escolar mencionado reflete, de forma estratégica, a igual crescente busca por bons índices nas avaliações em larga escala.

Objetivos: descrever o perfil clínico e sociodemográfico de idosos portadores de transtorno de humor depressivo. Métodos: estudo transversal, que abrangeu os dados da primeira consulta de todos os indivíduos com idade igual ou superior a 60 anos atendidos no ambulatório de Psiquiatria Geriátrica de um hospital terciário, no período de 2014 a 2019, com diagnóstico de depressão. Os aspectos clínicos psiquiátricos avaliados foram a razão da procura por atendimento, a presença de alguma comorbidade clínica, as internações psiquiátricas prévias e o diagnóstico de depressão unipolar estabelecido com base no DSM-5. As informações sociodemográficas foram idade, sexo, estado civil, escolaridade e atividade laboral. Resultados: um total de 119 participantes com diagnóstico de Transtorno Depressivo Maior foram inseridos no estudo. A média de idade foi de 70,9±7,4 anos e 83,2% do sexo feminino. Os homens depressivos eram, na sua maioria, da faixa etária dos 70 aos 79 anos, enquanto as mulheres eram mais jovens (60 aos 69 anos). Os idosos mais jovens com depressão eram casados (52,9%), enquanto os mais velhos eram viúvos. Em relação à escolaridade, os idosos mais velhos tinham menos anos de estudo. Grande parcela dos idosos com depressão apresentava algum tipo de comorbidade clínica (86,4%).Conclusões: assim, com envelhecimento da população, conhecê-la com maior aprofundamento torna-se uma ferramenta útil para melhor tratá-la. Além disso, quanto mais conhecimento possuímos melhor conseguimos otimizar nossos recursos.

Aim. To evaluate the predictive potential of the parameters of complete blood count (CBC), lipid profile and their ratios for predicting obstructive coronary artery disease (oCAD) in patients with non-ST elevation acute coronary syndrome (NSTEACS).

Material and methods. The study included 600 patients with NSTE-ACS with a median age of 62 years who underwent invasive coronary angiography (CA). Two groups were formed, the first of which consisted of 360 (60%) patients with oCAD (stenosis ≥50%), and the second — 240 (40%) with coronary stenosis <50%. The clinical and functional status of patients before CAG was assessed by 33 parameters, including parameters of CBC, lipid profile and their ratio. For statistical processing and data analysis, the Mann-Whitney, Fisher, chi-squared tests, univariate logistic regression (LR) were used, while for the creation of predictive models, multivariate LR (MLR) was used. The quality was assessed by 4 metrics: area under the ROC curve (AUC), sensitivity (Se), specificity (Sp), and accuracy (Ac).

Results. CBC and lipid profile analysis made it possible to identify factors that are linearly and non-linearly associated with oCAD. Univariate LR revealed their threshold values with the highest predictive potential. The quality metrics of the best prognostic model developed using MLR were as follows: AUC — 0,80, Sp — 0,79, Ac — 0,76, Se — 0,78. Its predictors were 8 following categorical parameters: age >55 years in men and >65 years in women, lymphocyte count (LYM) <19%, hematocrit >49%, immune-inflammation index >1000, high density lipoprotein cholesterol (HDL-C) to low density lipoprotein cholesterol (LDL-C) ratio <0,3, monocyte (MON)-to-HDL-C ratio >0,8, neutrophil (NEUT)-to-HDL-C ratio >5,7 and NEUT/LYM >3. The relative contribution of individual predictors to the development of end point was determined.

Conclusion. The predictive algorithm (model 9), developed on the basis of MLR, showed a better quality metrics ratio than other models. The following 3 factors had the dominant influence on the oCAD risk: HDL-C/LDL-C (38%), age of patients (31%), and MON/HDL-C (14%). The influence of other factors on the oCAD risk was less noticeable.

Published: September 2022

Aim. To compare the results of diagnosing heart failure with preserved ejection fraction (HFpEF) in patients with hypertension (HTN) according left atrial (LA) strain values with the results obtained using the H2FPEF score and diastolic stress testing (DST).

Material and methods. The study included 293 patients with previously established HTN who were examined due to complaints of shortness of breath and/or palpitations (men, 97 (33,5%), mean age, 62,0 (55,0; 67,0) years). All patients underwent transthoracic echocardiography with the assessment of LA strain parameters and probability of HFpEF using the H2FPEF score. Eighty five patients with an intermediate probability of HFpEF underwent DST.

Results. A low probability of HFpEF according to the H2FPEF score was registered in 35 (11,9%) patients, uncertain — in 206 (70,3%), high — in 52 (17,7%). DST was negative in 43 (50,6%) and positive in 42 (49,4%) patients with an intermediate probability of HFpEF. LA strain in the reservoir phase in patients with a low probability of HFpEF averaged (median and interquartile interval) 28,0 (23,6; 31,5)%, while in patients with an intermediate probability and negative DST — 24,0 (22,0; 26,8)%, with an intermediate probability and positive DST — 20,0 (18,0; 21,0)%, and with a high probability of HFpEF — 19,6 (16,9; 21,8)%. HFpEF was diagnosed in 94 patients, including 52 with a high probability on the H2FPEF score and 42 with an intermediate probability and positive DST. The diagnosis of HFpEF was ruled out in 78 patients, including 35 with a low probability on the H2FPEF score and 43 with an intermediate probability and negative DST. Further, 172 patients with confirmed or excluded HFpEF were randomly divided into two equal cohorts. In the training cohort, HFpEF was diagnosed in 44 (51,2%) patients, in the validation cohort — in 50 (58,1%). ROC analysis performed on the training cohort for the LA strain in reservoir phase showed AUC of 0,920 (95% confidence interval (CI), 0,842-0,968) and cut-off point of 21,5%. In the training cohort, the results of HFpEF diagnosis using the indicated criterion coincided with those using H2FPEF score and DST in 86,1% (95% CI, 77,2-91,8) of cases. The Cohen’s kappa was 0,721 (95% C,I 0,575-0,868). In the validation cohort, agreement was observed in 84,9% (95% CI 75,8-91,0) of cases with Cohen’s kappa of 0,702 (95% CI 0,553-0,851).

Conclusion. In hypertensive patients, the diagnosis of HFpEF made on the basis of a decrease in the LA strain in reservoir phase to ≤21,5%, is in good agreement with the diagnosis made using the H2FPEF score and DST.
