Reliable, wide range, and highly sensitive joint movement monitoring is essential for training activities, human behavior analysis, and human-machine interfaces. Yet, most current motion sensors work on the nano/microcracks induced by the tensile deformation on the convex surface of joints during joint movements, which cannot satisfy requirements of ultrawide detectable angle range, high angle sensitivity, conformability, and consistence under cyclic movements. In nature, scorpions sense small vibrations by allowing for compression strain conversion from external mechanical vibrations through crack-shaped slit sensilla. Here, we demonstrated that ultraconformal sensors based on controlled slit structures, inspired by the geometry of a scorpion’s slit sensilla, exhibit high sensitivity (0.45%deg
-1
), ultralow angle detection threshold (~15°), fast response/relaxation times (115/72 ms), wide range (15° ~120°), and durability (over 1000 cycles). Also, a user-friendly, hybrid sign language system has been developed to realize Chinese and American sign language recognition and feedback through video and speech broadcasts, making these conformal motion sensors promising candidates for joint movement monitoring in wearable electronics and robotics technology.

Published: June 2021

Hurricanes are known to play a critical role in reshaping coastlines, but often only impacts on the open ocean coast are considered, ignoring seaward-directed forces and responses. The identification of subaerial evidence for storm-induced seaward transport is a critical step towards understanding its impact on coastal resiliency. The visual features, found in the National Oceanic and Atmospheric Administration, National Geodetic Survey Emergency Response Imagery (ERI) collected after recent hurricanes on the U.S. East Atlantic and Gulf of Mexico coasts, include scours and channelized erosion, but also deposition on the shoreface or in the nearshore as deltas and fans of various sizes. We catalog all available ERI and describe recently formed features found on the North Core Banks, North Carolina, after Hurricane Dorian (2019); the Carolina coasts after Hurricane Isaias (2020); the Isles Dernieres, Louisiana, after Hurricane Zeta (2020); and the southwest coast of Louisiana, after Hurricanes Laura and Delta (2020). Hundreds of features were identified over nearly 200 km of coastline with the density of features exceeding 20 per km in some areas. Individual features range in size from 5 m to 500 m in the alongshore, with similar dimensions in the cross-shore direction, including the formation or reactivation of outlets. The extensive occurrence of these storm-induced return-flow and seawardflow morphologic features demonstrates that their role in coastal evolution and resilience may be more prominent than previously thought. Based on these observations we propose clarifying terms for return- and seaward-flow features to distinguish them from more frequently documented landward-flow features and advocate for their inclusion in coastal change hazards classification schemes and coastal evolution morphodynamic models.
Informes de Mercado, su uso en la Argentina
Authors: Leavy Sebastián , Allen Bárbara , Qüesta Mónica , Piermatei Cecilia
Published: June 2021

La economía neoclásica considera como agente decisor al que maximiza su utilidad y las empresas sus ganancias en presencia de información completa y relevante. El productor agropecuario debe dar respuesta a los interrogantes que surgen en el momento de la siembra: qué producir, en qué cantidad, cuándo y a quién vender. Si la empresa produce “commodities”, el precio lo determina el mercado. En las economías en las cuales el mercado regula la actividad productiva a través del precio, la información juega un papel de suma importancia. El objetivo del trabajo es identificar, caracterizar y seleccionar los informes de mercado relevantes a nivel internacional y nacional utilizados por el productor agropecuario. Se realizan entrevistas semiestructuradas a informantes calificados y a actores del medio bajo estudio, sobre una muestra no probabilística intencional. Los resultados muestran la relevancia de los informes del USDA y de la Bolsa de Comercio de Rosario como fuente de información de mercados internacionales y nacionales respectivamente. La superficie trabajada es una variable a considerar, ya que los productores medianos y grandes son los que utilizan este tipo de informes. Cabe destacar que estos últimos manejan más asiduamente los informes internacionales. Los productores de menor superficie no usarían informes de mercados.

At the Origins of the Natural Focality Concept
Authors: Shchelkanov MYu , Leonova GN , Galkina IV , Andryukov BG
Published: June 2021

Introduction: The article analyzes the course of scientific research that led to the discovery of tick-borne (Amarillovirales: Flaviviridae, Flavivirus) and Japanese (Amarillovirales: Flaviviridae, Flavivirus) encephalitis viruses and further formulation of the basic principles of functioning of natural foci of vector-borne infections. Materials and methods: We did a literature search in the State Archive of the Primorsky Krai, the Vladivostok City Archive, the Web of Science, PubMed, Scopus, Elsevier, Springer, and Google Scholar databases. Results: In the late 1930s, the Ussuri taiga became a “cradle” of the concept of natural focality first formulated by Academician Yevgeny N. Pavlovsky in 1939. Originally encompassing vector-borne infectious diseases this concept was later expanded to include non-vector-borne infections and sapronoses. A great contribution to the meaningful evolution of the theory of sapronoses was made by Academician Georgy P. Somov (Vladivostok). Conclusion: Establishment in May 1941 of a predecessor of the modern Research Institute of Epidemiology and Microbiology named after G.P. Somovbelonging to the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing became one of the elements of consistent strengthening of the biological security of the country in the Far East.

Quickly Transforming Discriminator in Pre-Trained GAN to Encoder
Authors: Yu Cheng , Wang Wenmin
Published: June 2021

Abstract-- Fine-designed deep Generative Adversarial Networks (GANs) can generate high-quality (HQ) images. However, the discriminator in GAN only plays a role to distinguish candidates produced by the generator from the true data distribution, and numerous generated samples are still not clear and true. From pre-trained GAN, we offer a self-supervised method to quickly transform the discriminator into an encoder and fine-tune the pre-trained GAN to an auto-encoder. The parameters of the pre-trained discriminator are reused and converted into an encoder for outputting reformed latent space. The transformation changes the previous GAN to a symmetrical architecture and the generator can reconstruct the HQ image by reforming latent space. By fixing the generator, the reformed latent space can perform better representation than the pre-trained GAN, and the performance of the pre-trained GAN can be improved by the transformed encoder.

Bagehot for Central Bankers
Authors:   Professor in economics at University of Western Brittany and research professor at University of Paris Panthéon La Sorbonne, France, Le Maux Laurent
Published: June 2021

Walter Bagehot (1873) published his famous book, Lombard Street, almost 150 years ago. The adage “lending freely against good collateral at a penalty rate” is associated with his name and his book has always been set on a pedestal and is still considered as the leading reference on the role of lender of last resort. Nonetheless, without a clear understanding of the theoretical grounds and the institutional features of the British banking system, any interpretation of Bagehot’s writings remains vague if not misleading—which is worrisome if they are supposed to provide a guideline for policy makers. The purpose of the present paper is to determine whether Bagehot’s recommendation remains relevant for modern central bankers or whether it was indigenous to the monetary and banking architecture of Victorian times.

Authors: Rahangdale Mrunal , Pandey Prachi
Published: June 2021

The apremilast is anti-inflammatory drug and PDE-4 inhibitor, used in treatment of psoriasis. The oral route of apremilast has limitation of GI irritation and frequent dosage regimen.The objective of the present work was aimed to prepare transethosomal gel of apremilast to achieve more skin permeation, more drug entrapment efficiency and sustained release. The transethosome vesicle containing apremilast was prepared by using Rotary vacuum evaporator, followed by probe sonication. The Box-Behnken design was used to optimize the formulation by taking quantity of lipoid        S 100, sodium cholate and ethanol as independent variable and vesicle size, entrapment efficiency and cumulative drug release as dependent variable. The optimized batch of transethosome vesicle was incorporated in 1 % of Carbopol gel base. The prepared optimized batch was evaluated for size, zeta potential, surface morphology, pH, viscosity, spreadability, extrudability, drug content and ex-vivo permeation studies. The result showed that optimized batch of transethosome was found to have vesicle size of 130.8 nm, entrapment efficiency of 62.83 % and cumulative drug release of gel 73.13 %. The transethosome vesicles were found to be spherical and uniform in size based on TEM analysis. The ex-vivo permeation studies were performed for 24 hrs through the rat skin. The formulation was found to show better skin permeation and sustained release. The formulation showed satisfactory result with respect to pH, gel characteristics and stability. Thus, can concluded that transethosomal gel containing apremilast could be an effective option for treatment of psoriasis.

Authors: Alotaibi Refah Mohammed , Tripathi Yogesh Mani , Dey Sanku , Rezk Hoda Ragab
Published: June 2021

In this paper, inference upon stress-strength reliability is considered for unit-Weibull distributions with a common parameter under the assumption that data are observed using progressive type II censoring. We obtain di_erent estimators of system reliability using classical and Bayesian procedures. Asymptotic interval is constructed based on Fisher information matrix. Besides, boot-p and boot-t intervals are also obtained. We evaluate Bayes estimates using Lindley's technique and Metropolis-Hastings (MH) algorithm. The Bayes credible interval is evaluated using MH method. An unbiased estimator of this parametric function is also obtained under know common parameter case. Numerical simulations are performed to compare estimation methods. Finally, a data set is studied for illustration purposes.

Published: June 2021

Background- Postoperative nausea and vomiting (PONV) is one of the most unpleasant complications after middle ear surgery. Several studies have demonstrated use of gabapentin as antiemetic. This study aims at comparison of intravenous granisetron vs oral gabapentin in preventing PONV. Methods - 64 patients of ASA I or II between the ages of 18 and 65 years were divided equally into two groups. Patients in group I received 3mg granisetron iv 2 minutes and patients in group II received 300 mg gabapentin orally 1 hour prior to surgery. Patients were premedicated with inj. glycopyrrolate and inj. midazolam. Anaesthesia was induced, maintained and reversed in usual manner. Haemodynamic changes and number of episodes of nausea and vomiting were recorded upto 24 hours postoperatively. No statistically significant difference was observed in both the groups at 0 and 1 hour in preventing PONV (p<0.05). Next 24 hours postoperatively neither group showed PONV. No significant haemodynamic changes were observed and there were noside effects in either of the groups.Conclusion- There was no statistically significant difference in prevention of PONV in the patients who had either received inj granisetron 3mg i.v. 2 minutes prior to surgery or oral Gabapentin 300mg 1hour prior to surgery after middle ear surgery without any side effects.

Published: June 2021

The purpose of this article is to examine the conversion of waste methane gas to renewable energy through environmental management. Processing organic waste is one kind of alternative energy that may be generated and regenerated. Garbage is a major issue for the majority of people, particularly the vast volume of market garbage. Waste processing and utilization technology is required. Implementing the 3R process of reduce, reuse, and recycle on fresh garbage not only generates useful goods, but also addresses the waste issue and generates revenue for those who wish to manage it. As a result, it is critical to evaluate the design of organic waste burners that convert methane gas to methane and to estimate the rate of combustion and heat produced by organic waste biogas

ОСОБЛИВОСТІ ЗМІСТОВНО-МОВНОЇ ІНТЕГРАЦІЇ У НАВЧАННІ СТУДЕНТІВ ІНЖЕНЕРНО-ТЕХНІЧНИХ СПЕЦІАЛЬНОСТЕЙ
Authors: Сотер М. В.
Published: June 2021

У статті наголошено, що сучасна парадигма іншомовної освіти у технічних закладах вищої освіти України повинна, передусім, орієнтуватися на побудову такої системи підготовки фахівців інженерно-технічних спеціальностей, яка би передбачала студентоцентризм, відкритість, гнучкість, мобільність, практичну спрямованість та інтеграцію, що у майбутньому надасть можливість фахівцю адаптуватися до мінливих умов професійної діяльності. Констатовано необхідність перенесення акцентів на оволодіння іноземною мовою шляхом інтеграційної взаємодії професійно-орієнтованих дисциплін та іноземної мови через імплементацію змістовно-мовної інтеграції у навчанні. Обґрунтовано необхідність залучення змістовно-мовної інтеграції у навчанні.Схарактеризовано ряд проблем, пов’язаних із практичним упровадженням змістовно-мовної інтеграції у навчанні в освітній процес технічних закладів вищої освіти: недостатній рівень володіння англійською мовою студентами і викладачами фахових дисциплін для представлення навчального матеріалу англійською мовою; труднощі у співпраці викладачів іноземних мов та викладачів фахових дисциплін щодо створення та розробки навчальних планів, програм, матеріалів; поліпшення знання англійської мови, як студентами, так і викладачами.Представлено особливості змістовно-мовної інтеграції у навчанні в умовах підготовки студентів інженерно-технічних спеціальностей: одночасне опанування іноземної мови і майбутнього фаху (професійно-орієнтованих дисциплін); навчання іноземної мови як засобу для викладання та засвоєння студентами позамовного змісту; автентичність навчальних матеріалів; побудова атмосфери співпраці, довіри й емпатії; формування активної особистості, готової до самоосвіти, саморозвитку, самовдосконалення; взаємодія викладачів іноземних мов та викладачів-предметників та ін.
СУЧАСНІ СВІТОВІ ПРАКТИКИ ОЦІНЮВАННЯ ЯКОСТІ ОСВІТНЬОЇ ДІЯЛЬНОСТІ ЗАКЛАДІВ ЗАГАЛЬНОЇ СЕРЕДНЬОЇ ОСВІТИ

Published: June 2021

У статті розкрито сучасні світові практики оцінювання якості освітньої діяльності закладів загальної середньої освіти в Україні, Фінляндії, Чехії, Сінгапурі.Автором статті проаналізовано проблеми реалізації функції контролю: порушення балансу між оцінюванням результативності діяльності організації та урахуванням інтересів працівників, формалізація контролю тощо. Визначено, що внутрішкільний контроль як складова управлінської діяльності є системою вивчення всіх аспектів діяльності закладу загальної середньої освіти з метою виявлення фактичного стану справ та запровадження заходів щодо покращення якості освіти.Оцінювання освітніх і управлінських процесів у закладах загальної середньої освіти в Україні здійснюється відповідно до компонентів внутрішньої системи забезпечення якості освіти, встановлених критеріїв та індикаторів із застосуванням адекватного інструментарію збору інформації.У фінській системі освіти обов’язковою складовою робочого плану є визначення сфер діяльності, що підлягають самооцінюванню, встановлення якісних або кількісних критеріїв оцінювання та планування зміни з удосконалення діяльності закладу освіти на основі результатів оцінювання.У чеській системі освіти оцінювання діяльності школи розглядають як поетапний процес: визначення предмета і цілей контролю, визначення критеріїв та індикаторів, отримання даних для визначення похибки, оцінювання, реалізація результатів.Сінгапурській освітній системі властива розвинена культура і структура підзвітності, що реалізується у форматі «Модель удосконалення школи» (SEM, 2000), і передбачає відстеження основних показників діяльності школи за двома категоріями: «Можливості» і «Результати».У статті зроблено висновок про те, що складовою всіх процесів забезпечення якості є оцінювання, що об’єднує дві споріднені цілі – підзвітність і підвищення якості.

Published: June 2021

Após várias décadas ausente da agenda política, a questão metropolitana vem apresentando uma série de avanços, ao longo dos últimos anos, no estado do Rio de Janeiro. Tais iniciativas culminaram na aprovação da Lei Complementar nº 184, de 27 de dezembro de 2018, que dispõe sobre a Região Metropolitana (RM), sua composição, organização e gestão, assim como trata da definição das funções públicas e serviços de interesse comum e, ainda, cria sua autoridade executiva e o Fundo de Desenvolvimento da Região Metropolitana. Desde a sua instituição como RM, em 1974, até 2018, verificaram-se algumas tentativas de retomada do tema, em geral, sem provocarem efeitos concretos. As alterações normativas que ocorreram no período pouco alteraram este cenário, notadamente restritas à alteração de sua composição. Há algumas particularidades importantes em relação à criação da RM do Rio de Janeiro frente às demais RMs, que ajudam a explicar as dificuldades que se impuseram ao avanço sistemático desta política no estado, desde as suas origens.
HOUSING PRICE CYCLES IN POLAND – THE CASE OF 18 PROVINCIAL CAPITAL CITIES IN 2000–2020
Authors: Trojanek Radoslaw
Published: June 2021

Using a unique dataset of 4,5 million offers, the housing cycles in 18 Polish provincial capitals were identified between 2000 and 2020 before and after the financial crisis. Differences in the course of the cycles depending on spatial diversity are presented, as well as differences in the strength of decreases and increases in individual phases. The examined housing markets in Poland have experienced significant variability in the extent of their cycles. One complete cycle was found in each of the analysed cities. Its average duration was approximately 12 years. In this cycle, residential prices (in real terms) increased by 88% on average, in the upward phase by 158%, while in the downward phase, they decreased by 27% in the cities under study. A correlation was found that implies that the higher the price rises in the upward period, the higher the price correction ensues in the cycle’s downward phase. Moreover, the similarity in fluctuations was present in the metropolitan markets in local housing markets, especially before the financial crisis. Apartment prices continued to grow by 2.9% on average in the real term during the COVID-19 pandemic in 2020.

AIM. The aim of the study was to analyze Avra's effector in inducing cancer stem cells into colon cancer through increased radical oxygen species (ROS), PTEN expression and c-myC as markers of tumorigenesis in mice model of the colorectal cancer infected with S. typhimurium. METHODS. The study used balb c mice induced once a week by 10 mg / mL / day of AOM for 1-week and 12-week treatment period. Isolation of S. typhimurium specific protein had been carried out before being induced to mice in intraperitoneal manner in the amount of 40 mL / 50 mL. Propagation of S. typhimurium ATCC bacteria with MacConkey media and isolation of S. typhimurium protein were administered. The sample was divided into 4 groups, positive control group (group that was only exposed to azoxymethane (AOM), group exposed to both AOM and AvrA (AOM + AvrA), and group exposed to both AOM and S. typhimurium (AOM + S. typhimurium). Blood flow cytometry and soft tissue sampling for IHC and data analysis were then conducted. RESULTS. The results of the study showed that there was an increase in the expression of ROS, PTEN and c-Myc. Increased ROS expression was found in the 12-week treatment period group and it was known that such increase was due to AOM + S. typhimurium (45.78 Â± 2.93) induction compared to AOM, AOM + AvrA and control (p <0.05). PTEN and C-myc expression increased at the 12th week compared to the negative control. CONCLUSION. Inflammation is the triggering factor for colorectal cancer, in which the expression of ROS, PTEN and c-Myc as the colorectal cancer markers increases in both the acute and chronic phases.

Authors: Amir Arni , Abeiasa M. Saka , Oktavianis Oktavianis
Published: June 2021

BACKGROUND: Basically, body regulates various harmful substances, including nicotine and tar which were carried by cigarette smoke. Nicotine which accumulated in blood was transported to liver to be metabolized and excreted in kidneys. The metabolism of nicotine into a harmless substance to body is closely related to the role of cytochrome P450 enzyme. In liver, nicotine was catalyzed by cytochrome P450 to be intermediate nicotine-Δ-1 ‘(5’) - iminium ion. The elevation of cholesterol leads the P450 to discard overage cholesterol to keep cholesterol homeostasis and atheroprotection.
AIM: The aim of the study was to determine the activity of cytochrome P450 to cigarette smoke exposure and to cholesterol level.
MATERIALS AND METHODS: A total of 32 Rattus norvegicus male Wistar albino strain was exposed to cigarette smoke with a different number of cigarettes for 57 weeks (2, 3, and 4 cigarette/day group, with a group of control). In the 58th week, the blood of rats was collected for enzyme-linked immunosorbent assay analysis.
RESULTS: Both cytochrome P450 activity and cholesterol level affected to cigarette smoke exposure (p > 0.05, 0.00 for cholesterol levels and 0.04 for p450 levels).
CONCLUSIONS: Exposure of cigarette smoke significantly has an impact on increasing cholesterol levels and decreasing the activity of P450 enzyme. The elevating of cigarette number had a significant impact between the smoker and non-smoker groups.

Published: June 2021

BACKGROUND: Hypertension is the most important preventable cause of morbidity and mortality in the world. Self-awareness of people with hypertension can reduce the mortality and morbidity rates of complications. One intervention to improve self-awareness is the establishment of a self-help group (SHG) for those willing to share their experiences and motivations on a supportive strategy to build self-awareness of hypertension.
AIM: This study was conducted to determine whether there was an effect of Self-help Group (SHG) intervention on the self-awareness of hypertensive patients in Mantrijeron sub-district of Yogyakarta.
METHODS: This study used a pre-experimental research method with one group pre-test and post-test design. Participants in the study amounted to 23 SHG members in Hamlet number 10 Jogokaryan, Mantrijeron Village, which were determined using the sample size estimation formula and the respondent's anticipation to drop out. The sampling technique used in this study is purposive sampling technique or a sample that has the criteria set by the researcher and the participants are willing to participate in the study.
RESULTS: The mean value of self-awareness before conducting SHG for hypertensive people at Mantrijeron was 48.35. The mean value of self-awareness after doing SHG in hypertensive patients at Mantrijeron is 62.39. The results of the paired sample t-test showed that there is significant effect of conducting SHG on the intervention group with p = 0.001 (p <0.05).
CONCLUSION: There is an effect of SHG on self-awareness before and after the SHG.

Published: June 2021

BACKGROUND: Internationally, many instruments have been designed to evaluate mental health knowledge; however, in pregnant women is very limited.
AIM: Therefore, this study aimed to develop and validate a survey to measure the mental health knowledge of pregnant women.
METHODS: In this cross-sectional study, 13 midwives attended the FGD and 10 pregnant women were invited for in-depth interviews to develop an item pool. The content validity was carried out by a panel of 6 experts. The face validity was performed with 5 pregnant women. Next, the construct validity test involved 150 pregnant women who were selected by stratified sampling from 13 public health centers in Surakarta, Indonesia. Analyses were conducted to check content validity, face validity, construct validity, internal consistency reliability, difficulty index, and exploratory factor analysis.
RESULTS: A final 20-item Mental Health Knowledge Scale (MHKS) has a content validity index of 0.97 and a correlation value per item greater than the r-table (i.e., 0.1603). In addition, the MHKS has a Kuder–Richardson 20 reliability coefficient of 0.717. Furthermore, the difficulty index ranged from 0.39 to 0.82 which was considered in the good and acceptable category. Construct validity was confirmed using exploratory factor analysis KMO = 0.713, Bartlett’s test p < 0.001.
CONCLUSION: Based on the findings, the final version of the MHKS was considered a valid and reliable tool. The instrument can be applied to measure the understanding of pregnant women about pregnancy depression. Further studies require adjustment items to other participants regarding mental health knowledge.

Published: June 2021

BACKGROUND: The conducive factor of stunting is the deficiency in nutrient intake due to the lack of quantity and quality of food consumed by the children. Children’s food consumption is strongly influenced by the mother’s nutritional knowledge and children’s feeding practices.

AIM: The aims of this study were to determine the effect of providing local snacks in South Sulawesi with a substitute of snakehead fish flour (Tibus) and virtual nutrition counseling on the growth of stunting children.

METHODS: The design of this study used a randomized pretest-posttest control design. The sample was divided in two groups using systematic random sampling. The first group was given local Tibus snacks and nutritional counseling virtually and the second group was only given virtual nutrition counseling. The intervention was carried out every day until 1 month. The sample of this research was mothers who have stunting children under five of age.

RESULTS: Nutrition knowledge of mothers in group one increased significantly before and after intervention (63.78 ± 1.68 vs. 73.70 ±1.35 points), but this was not the case in group two. The increase in maternal nutritional knowledge was higher in group one than in group two, although it was not significant (p = 0.91). The comparison of the weight gain of children in group one versus group two was 0.37 ± 0.49 kg versus 0.07 ± 0.39 kg (p = 0.021). The increase in the height of the children in group one before and after was 84.15 ± 7.79 cm versus 85.97 ± 7.95 cm (p = 0.000). The ratio of the increase in the height of the children in group one and group two was 1.82 ± 0.94 cm versus 1.53 ± 0.68 cm (p = 0.402).

CONCLUSIONS: Nutrition counseling virtual can increase nutrition knowledge. The providing of local snacks (Tibus) accompanied by virtual nutrition counseling can increase growth in body length and weight of stunting children. The efforts to accelerate prevention stunting in children under five can be done with utilization of local snacks.

Published: June 2021

BACKGROUND: Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease affects about 0.5–1% of adults. Sexuality is an integral part of human quality of life and responsible for our individual welfare, study the association between them is highly important as many studies revealed that sexuality is greatly affected in RA patients.

AIM: This study aims to determine the possible different risk factors for sexual dysfunction (SD) in RA and to study the magnitude of SD among RA male patients.

METHODS: This is a case–control study carried on 60 males – aged between 18–45 years – attending Family Medicine and Rheumatology Clinic in Kasr Alainy, Cairo University, Egypt. Participants were divided into case and control groups, both groups were matched regarding socioeconomic status. All participants were evaluated for sexual function using international index of erectile function (IIEF), psychological state using patient health questionnaire (PHQ9), disease-related disability using health assessment questionnaire, disease severity using disease activity score 28, and serum testosterone level was assessed.

RESULTS: There was a statistically significant difference between both groups regarding IIEF (OR o’s SD among patients were 1.66), PHQ9, and serum testosterone (p = 0.005). There was highly statistically significant negative correlation between sexual problems and depression, disease caused disability, RA duration and there was highly statistically significant positive correlation between sexual problems and serum hormonal level.

CONCLUSION: Sexual problems are a prominent problem in males who suffer from RA. Sexual function was significant associated with disease activity, depression, quality of life, and with lower levels of total and free testosterone.
