Comparative Analysis of Conventional, Sonic and Laser Activated Irrigation Methods on Fracture Resistance of Endodontically Treated Roots: An in vitro Study
Authors: Abdulrahman Shelan , Faraj Bestoon
Published: December 2023

Objective: To compare the effect of different irrigation activation methods on the fracture strength of endodontically treated roots.

Methods: Sixty extracted single-rooted mandibular premolars with single canals were used. The specimens were instrumented with ProTaper Next rotary instruments up to size X3 and were randomly split into four groups (n=15) according to final irrigation procedures: Group I: Conventional syringe irrigation with distilled water, Group II: Conventional syringe irrigation with NaOCl and EDTA, Group III: Sonic-activated irrigation with EndoActivator and Group IV: Laser-activated irrigation with Er-Cr: YSGG. Using a single-cone technique, root canals were obturated with gutta-percha and AH Plus root canal sealer. All samples were embedded in self-curing acrylic resin and subjected to axial forces by mechanical compression testing in a universal testing machine at 1 mm/min until fracture occurred. The data were evaluated statistically by using analysis of variance (one-way ANOVA) (P < 0.05).

Results: Conventional syringe irrigation with distilled water showed the highest mean value of fracture resistance and Laser-activated irrigation with Er, Cr: YSGG showed the lowest mean value of fracture resistance. In general, statistical analyses showed a non-significant difference between all tested groups (P > 0.05). 

Conclusions: The fracture resistance of roots treated endodontically was found to be unaffected by different activation methods. However, Laser-activated irrigation with Er-Cr: YSGG resulted in the greatest reduction of fracture resistance in comparison to the other groups.

Authors: Darweesh Rami , Al-Zahawi Abdulsalam
Published: December 2023

Objective: To investigate the influence of immediate and delayed dentin sealing technique on shear bonding strength (SBS) of the lithium disilicate glass-ceramic on tooth structure with different depths. Methods: The buccal surfaces of 40 maxillary first premolars were prepared with two different depths (1mm and 1.5 mm) and two different timings for bonding (immediate and delayed dentin sealing). G1 (1 mm preparation) and G2 (1.5 mm preparation) were  treated with bonding (Tetric N-Bond Universal, Ivoclar,2021, Schaan/Liechtenstein) two weeks after preparation, before cementation to the ceramic block with delayed dentin sealing (DDS), while G3 (1 mm preparation) and G4 (1.5 mm preparation) were treated immediately after preparation with bonding and immediate dentin sealing (IDS). All specimens were stored in artificial saliva (Biotene dry mouth, GSK goupe, Canada) for two weeks at 24℃. Forty lithium disilicate glass-ceramic rectangular blocks (Rosetta SM) (HASSBIO, Korea) with dimensions of (2 mm height, 2mm width and 3 mm thickness) were prepared. After preparation of the tooth surfaces, all prepared blocks were cemented to the prepared teeth in  groups GI and G2 with phosphoric acid 37% for 15 seconds, and all ceramic fitting surfaces were treated with 10% hydroflouric acid for 20 seconds and coupling agent monobond, then aging was performed for 5000 cycles in artificial saliva from 5-55 °C for all specimens. A universal test machine was used to test the shear bond strength (SBS). The statistical analysis was done using a one-way ANOVA test followed by Tukey's post hoc test (p<0.05). Results: The result revealed that IDS and minimum preparation depth had significantly higher bonding strength than DDS. Bonding strength in sequence was 15.50 ± 3.873 MPa in G3 and G4 8.25 ± 3.344 MPa, while for delayed dentin sealing the bonding strength was 7.75 ± 2.993 in G1 and 6.25 ± 2.125 MPa in G2. Conclusions: Teeth treated with IDS immediately after preparation showed significantly higher bonding strength than those treated with DDS for indirect ceramic restoration. Also, increase in the depth of the preparation toward the dentin led to a decrease in the bonding strength of the restoration.

Published: December 2023

The Bulak cave is in the village of Bulak near Safranbolu city. It’s one of the longest caves in Türkiye, which goes 6 kilometers into the inside, but approximately 400 meters are accessible to visitors. You require a professional guide and special equipment to travel further into the cave with lakes, a waterfall, and rivers which are essential for cavers, tourists, and researchers. However, there are possible several health problems for cave visitors. This study mainly aims to measure the radon concentrations with the nuclear track CR-39 detector in the cave environment. Twenty-two detectors were distributed inside the tourist’s area, and another six detectors were in the cave’s deeper region. The exposure time was one month on 24 September 2020, in addition to two soil samples collected from the cave used for medical purposes. These detectors are collected after 30 days and then etched with a chemical solution. The radon concentrations were calculated, which ranged between 16.437 (Bq/m3) and 48.652 (Bq/m3) using an optical microscope from the track density in detectors. The minimum and maximum values of radiation indices AED (mSv/y), LCR (WLM), PAEC (mWL), Dsoft (nGy/h), Dlung (nGy/h) and Heff (nSv/h) are presented, and all results for the radon and radiation indices are within the global limit. Radon concentrations for two soil samples were 26.956 (Bq/m3) and 59.172 (Bq/m3), and all the results were within the acceptable limits recommended by ICRP and UNSCEAR. The XRF examination was performed, which indicated the presence of Fe, Cu, Zn, As, and Mn minerals with high concentrations of 101607, 552, 1337, 237, and 1601 ppm, respectively, which are all more than the world permissible limits. The XRD analyses for the soil sample indicated the presence of clay and non-clay minerals such as Feldspar, Quartz, Gypsum, Calcite, Palygorskite, Kaolinite, and Montmorillonite.

Published: December 2023

Objective. Elaboration of a model to assess the risk of radicalisation in adolescence.
Background. The problem of radicalisation in adolescence is one of the most important problems in modern society, the search for mechanisms of radicalisation, as well as the development of preventive measures are in the focus of attention of researchers.
Methodology. In the logic of the social identity approach and based on the uncertainty-identity theory of M. Hogg, a model for assessing the risk of radicalisation in adolescence is formulated and outlined.
Conclusions. The formulated model for assessing the risk of radicalisation in adolescence postulates: individuals with multiple social identities and individuals without multiple social identities differ in groups that attract them (groups that provide them with meaningful positive social identity): those without multiple social identities have a preference for a group that would give them an clear and certain prototype.

Authors: Rahman A.A. , Azizah N. , Nurdin F.S.
Published: December 2023

Objective. Exploration of the psychological factors of conflict-related action among Sundanese Muslim students in Indonesia.
Background. Religious-based conflicts have been widely examined in various disciplines, attracting responses and factors in every cultural context.
Study design. Study 1 used an indigenous-based survey and was analyzed by thematic analysis. Study 2 examined the role of political ideology and perceived injustice in conflict-related behavior using hierarchical regression analysis.
Participants. Study 1: 224 people (35,7% of men, 64,3% of women) from 18 to 49 years old (M = 20,98; SD = 3,72). Study 2: 494 people (35,6% of men, 64,4% of women) from 17 to 49 years old (M = 20,00; SD = 1,52).
Measurements. Indonesian-language versions of the scales of religious fundamentalism ideology by Muluk and colleagues, violent extremist attitude by Nivette and colleagues, nonviolent direct action by Brown and colleagues, and sensitivity to injustice by Schmitt and colleagues.
Results. Study 1 showed specific patterns of cognitive, emotional, and behavioral responses. There are differences in the respondents' responses to conflicts between and within religions. These differences are caused by ideology orientation towards religion and perception of injustice towards their groups. Study 2 confirmed Study 1 that religious fundamentalism predicts both violent and nonviolent behavior. Also, perceived injustice of victims moderates the effect of religious fundamentalism to violent behavior. Meanwhile, perceived injustice of perpetrators predicts only nonviolent behavior.
Conclusions. There is a significant effect of religious-based ideology and perceived injustice on conflict-related behavior in the Sundanese Muslim context.
Procedural Justice as a Factor of Attitudes Toward the Political System: the Role of the Country's Economic Situation
Authors: Gulevich O.A.
Published: December 2023

Objective. The aim of the study is to analyze the relationship between perceived procedural justice in the political sphere, the perceived economic situation of the country, and attitudes toward the political system in Russia.
Background. Previous research has shown that the perceived procedural justice of politicians and political institutions improve attitudes toward them, satisfaction with their actions, and agreement with their decisions. Furthermore, adherence to procedural justice norms can offset the negative impact of economic problems. However, these studies have several limitations related to the sample and the method, which were taken into account in our study.
Participants. In the study, 8520 Russian citizens participated (N1 = 3193, N2 = 3237, N3 = 2090).
Study design. Respondents participated in an online survey conducted on the YandexToloka platform. The study involved three measurements: the first measurement took place in September 2022, and the second and third measurements were conducted in November 2022.
Measurements. Respondents filled out questionnaires to measure perceived procedural justice in politics, perceived economic situation, and attitude toward the Russian political system (social system justification, trust in federal political institutions, and emotion toward the political system).
Results. The study showed that both perceived procedural justice and the perceived economic situation of the country were positively related to the attitude toward the Russian political system. However, assessments of economic situation and procedural justice interacted with each other: the lower respondents rated the country's economic situation, the stronger the relationship between perceived procedural justice and attitude toward the political system.
Conclusions. Russians' ability to influence political decisions, the observance of equal rights, and respectful treatment by government representatives support the political system within which these occur. This becomes especially important during times when the country faces economic difficulties.

Authors: Fabrykant M.S.
Published: December 2023

Objective. Analysis of the effect of social trust on anxiety regarding the occurrence of various negative circumstances in the future.
Background. Experiences of instability and uncertainty prompt us to reconsider the role of social trust. It is important to determine whether social trust is an independent factor that reduces anxiety about the future, or only an effect of the possession of other resources.
Study design. The study examined the main effects of social trust on anxiety regarding the occurrence of various negative circumstances and the interaction effects of trust with other resources. The presence of significant effects and their direction were tested using multilevel ordinal logistic regression analysis. Participants. Data from Wave 7 of the World Values Survey, collected 2017-2021 in 62 countries. Country sample sizes range from 1000 to 3200.
Measurements. Items from the World Values Survey are indicators of generalized social trust and anxiety regarding various negative circumstances, as well as sociodemographic variables. GDP per capita at purchasing power parity.
Results. Social trust reduces anxiety about the future. This effect is independent and manifests itself when controlling for the level of possession of other resources. There also exists a negative interaction effect between social trust and other resources.
Conclusions. Social trust reduces anxiety about the future and enhances a similar effect for indicators of the possession of other resources.

Published: December 2023

Objective. The study of the influence of prolonged stressful situation on world assumptions, peculiarities of thinking and moral decisions.
Background. The pandemic situation can be considered as a model stressful situation. The assessment of its impact makes it possible to predict the consequences of society experiencing a high level of stress in a situation of danger and/or uncertainty.
Study design. The level of distress, moral decisions, world assumptions, and peculiarities of thinking before the pandemic and in the conditions of the pandemic were compared. Methods of variance analysis, the Kraskal-Wallace criterion, and correlation analysis were used.
Participants. "Moral dilemmas" N = 621 (23,4% of men), age – 33,7 ± 11,32; Constructive thinking questionnaire N = 700 (20,7% of men), age – 31,55 ± 9,7; Scale of basic beliefs N = 412 (18,2% of men), age – 35,6 ± 11,2.
Measurements. "Moral dilemmas", "World Assumptions Scale” (WAS), “Constructive Thinking Inventory” (CTI), Symptom Check List-90-Revised (SCL-90R).
Results. During the pandemic, the level of distress experienced is higher, the ability to distinguish between personal and "distant" violence is lower, and indicators of constructive thinking and emotional coping are lower. The belief in benevolence, justice of the world, the value of one's own self is reduced. All these changes are associated with a high level of distress.
Conclusions. The stressful situation led to a change in moral decisions. The change was not directly related to basic beliefs and thinking patterns and is a consequence of "emotional detachment" in stressful situation.

to Itraconazole
Authors: Kim Jin Ho , Bang Yong Jun , Jun Jae Bok , Lee Weon Ju
Published: December 2023

Purpureocillium lilacinum is a saprophytic fungus with a ubiquitous environmental distribution. Unfortunately, no standard treatment has yet been established for cutaneous P. lilacinum infections. Based on the in vitro antifungal susceptibility test, posaconazole has been considered an effective treatment option. We herein present a case involving a 72-year-old woman who visited our clinic due to a peripherally spreading, well-demarcated, asymptomatic, scaly, and erythematous patch on her forehead that had persisted for 4 months. She had been diagnosed with cutaneous P. lilacinum infection and had been treated with itraconazole (200 mg/day). However, the lesion recurred in the same area. Histopathological findings revealed suppurative granulomatous dermatitis with fungal elements. Fungal culture confirmed P. lilacinum regrowth. Posaconazole was selected to treat the recurrence of P. lilacinum infection. After 10 weeks of treatment, the lesion decreased dramatically without any adverse drug events. We recommend posaconazole as a treatment option for P. lilacinum infection refractory to itraconazole.

Published: December 2023

Introduction: in out-of-hospital cardiac arrest, early and efficient intervention through cardiopulmonary resuscitation (CPR) maneuvers and the use of the automated external defibrillator (AED) are the cornerstone for survival. Instruments that improve education would increase the responsiveness of lay personnel. Objectives: to develop, validate and evaluate a knowledge test on cardiopulmonary resuscitation and correct use of the automated external defibrillator in Asunción during 2023. Methodology: observational cross-sectional study, non-probabilistic sample for convenience of lay personnel users of mass attendance centers in Asunción. An exclusive questionnaire was developed on knowledge in cardiopulmonary resuscitation and the use of the automated external defibrillator (KOR-AED) based on the chain of survival in out-of-hospital cardiac arrest. Content, construct, and internal consistency were validated using expert opinion, factor analysis and Cronbach's alpha. Results: a total of 200 lay people participated, mostly shopping mall customers, with a predominance of men (63.5 %) (127), between 25-29 years old 28.5% (57). 61.5 % (123) had a university education, 75.5 % (151) had not related to health, 52 % (104) had prior knowledge of CPR, but 81.5 % (163) did not. The test showed reliability and suitability for factor analysis (Cronbach's alpha 0.75, Kaiser-Meyers-Olkin; 0.78, Bartlett p<0.05). The questions covered the first three links in the chain of survival, with items of medium to high difficulty. Women performed significantly better (p=0.04). Conclusion: the KOR-AED test is a valid and reliable instrument to improve the education of the layperson in CPR and use of the AED based on the chain of survival.
Influence of Phacoemulsification on Intraocular Pressure in Patients with Glaucoma
Authors: Voronin G. V. , Bersunkaev M. K. , Volzhanin A. V.
Published: December 2023

Phacoemulsification (PE) is a current ‘gold standard’ of the surgical treatment of the cataract. Apart from lens extraction and intraocular lens implantation, PE is accompanied by IOP changes in most cases. In cases of ophthalmic hypertension or primary open-angle glaucoma, IOP is most often decreased; however, the mechanism of this phenomenon is currently completely unknown. In closed-angle glaucoma, PE provides opening of the anterior chamber angle, which restores physiological outflow of intraocular fluid and leads to IOP stabilization. In some cases, however, PE may be accompanied by a short-term increase in IOP. The exact mechanism of this reaction is unknown, however, in most cases it is associated with the inflammatory response of the eye to surgical trauma.

Materials and methods. 87 eyes were examined after radial keratotomy, the average age was 59.8 ± 0.83 years. With glaucoma 47 eyes, without — in 40 eyes. Patients were divided into three groups: 17 eyes with a central corneal thickness (CCT) of less than 530 microns; 30 eyes with a CCT of 530–580 microns; 40 eyes with a CCT of more than 580 microns. The control group consists of myopic patients without glaucoma, without PES, over 45 years old. Corneal tomography and biomechanical parameters were measured using Pentacam (Oculus) and CorVis ST, respectively. Results. in the eyes after RK, the corneal stiffness (DA ratio, R) is higher in comparison with the control and increases with an increase in CCT. The stiffness of the fibrous capsule of the eye (SP-A1) after RK is reduced in comparison with the control and increases with an increase in CCT. The SSI analysis showed a higher stiffness of the eyeball than in the control, regardless of the CCT. BGF is higher in the eyes after RK compared to the control with the maximum value for thin corneas. Hyperopic shift (HS) after RK is distinctive for eyes with glaucoma. With a CCT of more than 580 microns, HS is a clinical glaucoma detector, with thin corneas, it is not. Conclusion. The eye after RC is characterized by an increase in the stiffness of the cornea, a decrease in the stiffness of the fibrous capsule of the eye, a general increase in the stiffness of the eyeball and HS.

Published: December 2023

Objectives: to evaluate the dynamics of changes in quality of life in patients with diabetic macular edema (DME) with vitrectomized and non-vitrectomized eyes after intravitreal injection of dexamethasone implant (IVD). Material and methods. 60 patients (60 eyes) were examined, divided into two groups with a diagnosis of diabetic retinopathy, DME and with different vitreous conditions. Group 1 — patients with non-vitrectomized eyes, group 2 — with vitrectomized eyes. Both objective and subjective methods of ophthalmological examination were used, followed by an assessment of the quality of life and visual functions based on the results of a questionnaire conducted to patients using VFQ-25 (visual function questionnaire — 25). Also, all patients of both groups were assessed for best corrected visual acuity (BCVA) before, 1, 3 and 6 months after IVD. Results. In both groups, an increase in the average BCVA after IVD was observed up to 3 months of monitoring (p < 0.01). In addition, the quality of life parameters increased after 1 month of steroid therapy in both groups (p < 0.05), and by 3 and 6 months this trend persisted mainly only for the group with vitrectomized eyes (p < 0.05). Conclusion. IVD in patients with DME can significantly improve the morphofunctional parameters of the macular zone in the eyes with both vitrectomized and non-vitrectomized eyes. The maximum effect of the drug according to the quality of visual functions assessment was observed in 1 month of monitoring in the group with non-vitrectomized eyes. At the same time, the longest increase in quality of visual functions parameters from 3 to 6 months was observed in the group with vitrectomized eyes.

Purpose. To study state of ocular hemodynamics in pregnant women with disorders of carbohydrate metabolism using color Doppler imaging. Patients and methods. 147 pregnant women were examined: 40 of them had type 1 diabetes mellitus (DM), 87 had gestational diabetes (GD); in 20 — pregnancy proceeded physiologically. Examination of pregnant women with DM was carried out in each trimester and 3 months after delivery, pregnant women with GD and control groups — once in the third trimester. The parameters of hemodynamics in the central retinal artery (CRA) and in the short posterior ciliary arteries (SPCAs) were studied using color Doppler imaging. Results. It was found that the peak systolic velocity (PSV) in the CRA was significantly lower in the GD and DM groups, while PSV in the SPCAs and end-diastolic velocity (EDV) in the CRA were higher in the control group compared to the GD. In SPCAs, the resistive index (RI) was the highest in the DM group, and the lowest in the GD group. Conclusion. In patients with GD in the third trimester of pregnancy, there is a statistically significant decrease in PSV and EDV in the CRA and SPCAs, combined with a decrease in RI in SPCAs, compared with patients with a physiological course of pregnancy. In patients with diabetic retinopathy (DR) in the third trimester of pregnancy, PSV and EDV in the CRA and SPCAs were significantly lower, and the pulsatility index (PI) and RI were significantly higher compared to pregnant women with DM without DR. In pregnant women with DR during gestation, there was a decrease in PSV and EDV against the background of an increase in RI and PI in the CRA and in the SPCAs. In pregnant women with DM and absence of DR during gestation, there was an increase in PSV, EDV and PI in the CRA and SPCAs from the first to the third trimesters. The revealed features of the state of hemodynamics in the CRA and SPCAs in pregnant women with DM with presence or absence of DR can become the basis for creating criteria for manifestation and progression of DR.

In connection with the problem of formation of strains of pathogenic microflora resistant to antibacterial drugs, research on the use of nanoparticles, namely quantum dots, has been actively conducted recently. Quantum dots can be used as an anti-infective agent, a means for visualization of intraocular structures, drug delivery, as well as a means for electrical stimulation of the retina. Successful application of quantum dots as an anti-infective agent necessitates the study of their penetrating ability into the anterior chamber. The aim of the study was to experimentally investigate the penetration ability of InP/ZnSe/ZnS 650 QDs in the anterior chamber of the eye at topical application. The object of the study was InP/ZnSe/ZnS 650 quantum dots. The study was carried out on laboratory rabbits (#6), which were divided randomly in pairs into groups. In rabbits #1 and #2 the eyes remained intact, #3 and #4 — a bandage soft contact lens was placed on the cornea of the right eye, #5 and #6 the cornea of the right eye was de-epithelialized. All experimental rabbits during the day 6 times instillation of 10 % solution of InP/ZnSe/ZnS 650 quantum dots was performed, and at the end 0.2 ml of moisture was taken from the anterior chamber of the right eye. The left eyes in all individuals were the control group. Identification of quantum dots into the anterior chamber was performed using a highly sensitive spectrophotometer UV-3600 (Shimadzu). The experimental study of the ability of InP/ZnSe/ZnS 650 quantum dots at topical application to penetrate into the intraocular cavity by the claimed detection methods did not allow their detection in the anterior chamber moisture even in minimal concentration.
Clinical Case of Postoperative Infectious Crystalline Keratopathy

Infectious crystalline keratopathy (ICK) is a sluggish infectious inflammation of the cornea. Described for the first time in 1983, it is currently a rare pathology. Most often, the etiological factor is gram-positive bacterial flora, which causes the typical formation of “crystals” in the anterior layers of the corneal stroma. Less often, infiltrates are formed by gram-negative bacterial flora, which is characterized by its location mainly in the posterior parts of the stroma. Atypical etiological agents include Mycobacteria and fungal microflora. The main predisposing factors for the development of ICK are drug immunosuppression and previous corneal surgery (through keratoplasty, layered keratoplasty, laser keratomilesis in situ — LASIK). This article describes an atypical clinical case of monolateral postoperative infectious crystalline keratopathy. The patient’s medical history includes bilateral LASIK surgery followed by drug therapy for postoperative keratitis of the right eye for 1 month.

From Disease Incubation to Disease Receipt: Representing Epidemics and Race in Pre- and Post-Second World War American Cinema (1931–1939 and 1950–1962)
Authors: Dung Phạm Thùy , Curtis Daniel R. , Han Qijun
Published: December 2023

This article analyses continuities and changes in how disease has been instrumentalised in cinema as a way of conceptualizing race—comparing five films depicting epidemics produced before the Second World War and five after. In the 1930s films, non-white populations often passively accept assistance in dealing with epidemic disease—a paternalistic white savior narrative—but not always with “gratitude”, and sometimes direct resistance. Here, epidemics take root in physical sites of economic “underdevelopment”, perpetuated further by perceived “premodern” cultural practices demarcated down the lines of race or ethnicity, and intersect with other gendered and socio-economic categories. After the war, while some cinematic tropes such as the “white knight” continue, other narratives emerge including a shift in emphasis away from the Othered environment as the nexus of disease (the disease’s “incubation”), and towards greater alarm about the appearance of disease within recipient, frequently white, communities.
Keeping Up With Atari: Neoliberal Expectations in Early Electronics Advertising
Authors: Moretti Myrna
Published: December 2023

During the early 1980s, ad campaigns framed purchasing and using emerging consumer electronics as tools for accessing, what Lauren Berlant called, ‘the good life.’ Computers, video games, VCRs, and cassette players might help consumers cultivate a neoliberal, upwardly mobile, and implicitly white, lifestyle. This paper explores early personal computer and home console video game advertisements as a cultural discourse that framed emerging technology through normative gendered, raced, and classed everyday lifestyles in an American context. The central case study is the early 1980s televisual ad campaign for the Atari 2600 system, featuring the “Have You Played Atari Today?” jingle. The campaign was widely viewed and is representative of contemporaneous marketing approaches. The ad’s allusion to time management both reinforced broader neoliberal paradigms and enacted a gendered slippage between labour and leisure. This paper draws from feminist critical theory approaches and uses textual analysis to understand the ways that electronic advertisements appealed to late capitalist social attitudes.

Local factors and global influences shape consumers’ perceptions through social media. In this regard, spice drinks as an agribusiness product have received increasing attention due to the Covid-19 pandemic. Therefore, understanding consumers’ perceptions is crucial for promoting the development of spice drinks. This study aims to (1) extract consumers’ perceptions of spice drinks based on discussions on social media using sentiment analysis and (2) classify the factors influencing their perceptions using factor analysis. The input dataset was obtained through Twitter data to acquire Kansei words. The results disclosed that Twitter could extract Kansei words and validate consumers’ perceptions of spice drinks as an agribusiness product. The sentiment analysis revealed 78% positive and 13% neutral tweets. Subsequently, an online survey was conducted among 495 respondents aged 18 to 41, distributed through various social media platforms from June to August 2022. The respondents were Generation Z and Millennials, with Generation Z referring to individuals born between 1997 and 2012 and Millennials born between 1981 and 1996. Factor analysis identified four principal components influencing consumers’ perceptions toward spice drinks: positive attitudes were associated with the quick, milky, mixed, healthy, quality, energy, fresh, warm, and safe; benefits were affiliated with the words enjoy, rest, life, smile, and story; quality concerned easy, flavour, and spicy; and sensory dealt with sweet, aroma, and bitter.

Manufacturing of valves generally uses brass alloy materials and is carried out using a forging process. In this research, the aim is to determine the effect of variations in heating temperature in the valve manufacturing process on the hardness value, microstructure, and shape changes that occur. This research method uses this research method, using an experimental method with temperature variations tested of (300˚, 400˚, and 500 ˚Celsius) with an unchanged compressive force and brass raw material with specifications Cu = 57%. Results of observations that occurred namely Hardness Testing, the lower the heating temperature, the higher the resulting hardness value, which is 69 HRb, 66 HRb, and 59 HRb. When the shape changes, the higher the temperature, the more flash you get, and the lighter the forging force on the forging tool. In the microstructure, as a result of temperature differences, each grain structure characteristic will be different, increasing temperature and forging pressure will change the grain structure.

Background: Menopause typically occurs between the ages of 45 and 55 and can significantly impact a woman's quality of life. Understanding the prevalence of menopausal symptoms and the strategies of coping with them is crucial for developing targeted interventions that address their unique needs.
Methods: This cross-sectional study targeted the Jordanian women aged 40-60 through online questionnaire during January 2023-June 2023. The menopause rating scale (MRS) was utilized to assess the severity of menopausal symptoms, including somatic, psychological, and urogenital domains.
Results: The study included a total of 309 successfully completed participations by women from different socio-economic and educational backgrounds in Jordan. The analysis revealed a high prevalence of menopausal symptoms among the participants. The severity of symptoms varied; moderate to severe symptoms, were appreciable across the various domains. The coping strategies employed by the participants were multifaceted. Unfortunately, a proportion of participants admitted to using ineffective coping mechanisms, such as tobacco and excessive caffeine consumption. In general, the study revealed that there is an evident shortage in the overall awareness among women.
Conclusions: The findings emphasize the necessity of comprehensive interventions to enhance the well-being of women and consequently the society. The qualitative and the quantitative aspects of the study shall contribute valuable perceptions to both of the academia and the authorized healthcare institutes.

Published: December 2023

Background: Placenta accreta spectrum disorder (PASD) is a complex obstetric condition associated with significant maternal and fetal morbidity and mortality. Despite its increasing global prevalence, there is limited research focusing on the fetal outcomes of PASD patients, particularly in Asian populations
Methods: This observational study was conducted at Cumilla medical college hospital over 18 months, starting from January 2022. A total of 60 patients diagnosed with PASD were included, following specific inclusion and exclusion criteria. Data were collected on sociodemographic characteristics, antenatal care, presenting complaints, and fetal outcomes.
Result: The study found that 90% of the participants had live births, while 10% experienced intrauterine death. Among the live births, there was a nearly equal distribution between low and normal birth weights. The sociodemographic distribution was diverse, with the majority of participants falling within the age range of 21-30 years. Half of the participants received regular antenatal care, and antepartum hemorrhage was the most common presenting complaint.
Conclusions: The study provides valuable insights into the fetal outcomes of PASD patients, with a notably high rate of live births. The findings also highlight the importance of regular antenatal care and early diagnosis in managing PASD effectively. The study serves as a foundation for future research aimed at improving both maternal and fetal outcomes in PASD.

Background: Preeclampsia is an abnormal elevation of blood pressure with systolic blood pressure ≥140 mmHg, and/or diastolic blood pressure ≥90 mmHg associated with proteinuria in a pregnant woman beyond 20 weeks of gestation. This generally disappears postpartum. Some women, however, will later on develop chronic hypertension. Our objective was to assess the determinants of occurrence of chronic hypertension in patients who had preeclampsia at the Yaoundé Central Hospital.
Methods: we carried out a retrospective case-control study over ten years from January 2012 to December 2022. The cases consisted of women who developed chronic hypertension within 5 years following an episode of preeclampsia in pregnancy. These were matched with two controls each; women who had not developed chronic hypertension following preeclampsia in pregnancy.
Results: We recruited 60 cases and 120 controls. After bivariate analysis, the sociodemographic factors seemingly associated with the occurrence of chronic hypertension were; age between 25-35 years p=0.01; OR=2.9 (1.5-5.5), the profession of pupil/student; p=0.05; OR=0.3 (0.12-0.7). The clinical factors found were multigravidas; OR=3.1 (1.6-5.9); p=0.00, as well as pauciparous women; OR=2.1 (1.1-4.4); p=0.03, family history of hypertension; OR=2.5 (1.3-4.8); p=0.04 and BMI greater than 40 kg/m2; OR=3.8 (1.0-13.6); p=0.02. After logistic regression, the factor independently associated with the occurrence of chronic hypertension is a family history of hypertension; p=0.01; OR=2.45 (1.18-4.96).
Conclusions: A family history of hypertension is a major risk factor for the occurrence of chronic hypertension in patients who have had preeclampsia.
