Background: Increased blood-brain barrier (BBB) permeability and amyloid-β (Aβ) peptides (especially Aβ1–42) (Aβ42) have been linked to Alzheimer’s disease (AD) pathogenesis, but the nature of their involvement in AD-related neuropathological changes leading to cognitive changes remains poorly understood. Objective: To test the hypothesis that chronic extravasation of bloodborne Aβ42 peptide and brain-reactive autoantibodies and their entry into the brain parenchyma via a permeable BBB contribute to AD-related pathological changes and cognitive changes in a mouse model. Methods: The BBB was rendered chronically permeable through repeated injections of Pertussis toxin (PT), and soluble monomeric, fluorescein isothiocyanate (FITC)-labeled or unlabeled Aβ42 was injected into the tail-vein of 10-month-old male CD1 mice at designated intervals spanning ∼3 months. Acquisition of learned behaviors and long-term retention were assessed via a battery of cognitive and behavioral tests and linked to neuropathological changes. Results: Mice injected with both PT and Aβ42 demonstrated a preferential deficit in the capacity for long-term retention and an increased susceptibility to interference in selective attention compared to mice exposed to PT or saline only. Immunohistochemical analyses revealed increased BBB permeability and entry of bloodborne Aβ42 and immunoglobulin G (IgG) into the brain parenchyma, selective neuronal binding of IgG and neuronal accumulation of Aβ42 in animals injected with both PT and Aβ42 compared to controls. Conclusion: Results highlight the potential synergistic role of BBB compromise and the influx of bloodborne Aβ42 into the brain in both the initiation and progression of neuropathologic and cognitive changes associated with AD.

Published: February 2024

The Cognitive Quotient (QuoCo) classification algorithm monitoring decline on age- and education-adjusted Mini-Mental State Examination (MMSE)-derived cognitive charts has proved superior to the conventionally-used cut-off for identifying incident dementia; however, it remains to be tested in different settings. Data were drawn from the Three-City Cohort to 1) assess the screening accuracy of the QuoCo, and 2) compare its performance to that of serial MMSE tests applying different cut-offs. For the QuoCo, sensitivity was 74.2 (95% CI: 71.4–76.8) and specificity 84.1 (83.6–84.7) and for the MMSE < 24, 64.1 (61.1–67.0) and 94.8 (94.4–95.1), respectively; whereas overall accuracy and sensitivity was highest for MMSE cut-offs <25 and <26. User-friendly charts for mapping cognitive trajectories over visits with an alert for potentially ‘abnormal’ decline can be of practical use and encourage regular monitoring in primary care where the <24 cut-off is still widely used despite its poor sensitivity.

BACKGROUND. Computed tomography (CT) plays a paramount role in the characterization and follow-up of Covid-19. Several scoring systems have been implemented to properly assess the lung parenchyma involved in patients suffering from Sars-Cov-2 infection, such as visual quantitative assessment score (VQAS) and software-based quantitative assessment score (SBQAS).

PURPOSE. This study aims to compare VQAS and SBQAS with two different software.

MATERIAL AND METHODS. This was a retrospective study; 90 patients were enrolled with the following criteria: patients’ age more than 18 years old, positive test for Covid-19, and unenhanced chest CT scans obtained between March and June 2021.
The VQAS was independently assessed, and the SBQAS was performed with two different Artificial Intelligence-driven softwares (Icolung and CT-COPD). The Intraclass Correlation Coefficient (ICC) statistical index and Bland-Altman test were employed.

RESULTS. The agreement score between radiologists (R1 and R2) for the VQAS of the lung parenchyma involved in the CT images was good (ICC = 0.871). The agreement score between the two software applications for the SBQAS was moderate (ICC = 0.584). The accordance between Icolung and the median of the visual evaluations (Median R1-R2) is good (ICC = 0.885). The correspondence between CT-COPD and the median of the VQAS (Median R1-R2) is moderate (ICC = 0.622).

CONCLUSION. This study showed moderate and good agreement regarding the VQAS and the SBQAS, enhancing this approach as a valuable tool to manage Covid-19 patients.

Purpose: Intensive military training courses are among the programs and specialties of the police force. Musculoskeletal disorders in the military are one of the vital factors that keep people away from courses and shorten their service life. This research aims to measure the prevalence of musculoskeletal injuries in newly arrived students in the pre-service training course of the police force using the Oslo Sports Trauma Research Center (OSTRC) questionnaire. Methods: For this purpose, 124 soldiers with a mean age of 20.7 years, a mean height of 178.5 cm, a mean weight of 72.9 kg, and a mean activity per week for 3 hours and 19 minutes in one of the training barracks affiliated to the Tehran Police Force and were selected and completed the OSTRC questionnaire every month for 6 months. The research design of this study is epidemiology and the results are presented descriptively. Results: The results of the research related to prevalence measurement on a monthly mean showed that ankles at 2.8%, knees at 2.2%, and waist at 1.8% respectively have the highest prevalence rates among soldiers. Also, among the harmful factors, the parade had the largest share with 22.5% and during 6 months, the second month had the highest number of injuries, and the sixth month had the lowest number of injuries. In terms of participation in exercises, 86.6% of soldiers participated in practical classes without any physical injuries during the six months. A total of 9.1% of the soldiers could not perform optimally and properly despite their full attendance in the practical classes due to physical injuries and finally, 3.8% of the participants, despite attending the practical classes, had to leave the class halfway due to the severity of the injury. Conclusion: What is clear is that the most affected areas are the central area and the lower limbs, and the spine of the back, head, neck, and upper limbs were not among the most damaged areas. Finally, it seems that the prevalence rate among the soldiers in training courses is acceptable and close to the average of global statistics. However, it is required to take preventive measures as well as plan to add classes and specialized exercises to strengthen physical fitness and specialized exercises related to improving the conditions of damaged areas.

Purpose: The purpose of this research was to compare the effect of video games, training with catalogs, and face-to-face training of the FIFA +11 warm-up program on the level of acceptance and belief of football players. Methods: The current semi-experimental research was done on 240 male players and coaches present in the premier soccer league of Khorasan Province who were randomly divided into four groups: 11+ face-to-face exercises, catalog, video games, and control (60 people in each group). Electronic questionnaires on acceptance and knowledge were filled by players and coaches. Then, the subjects of the training groups performed the exercises in three 15-minute sessions per week for eight weeks. Kruskal-Wallis test and marginal mean were used to check differences between the groups. Results: After eight weeks of training, there was a significant difference in the knowledge and awareness of the players between the four groups (P<0.05). Also, the marginal average test results showed that the effect of these exercises on the level of knowledge and awareness of the players was greater in the face-to-face group than in other groups. Also, 33.3% of the players considered these exercises to be boring and 23.7% of the players considered the limitation of time to do other exercises and soccer skills as one of the factors that prevent them from doing the exercise. Conclusion: Football players had low levels of knowledge and awareness of 11+ exercises, which increased after eight weeks of 11+ exercises using face-to-face exercises, catalogs, and videos.

Objectives Andropause is the common term for menopause in older men, which is characterized by a decrease in testosterone levels. Many elderly men with andropause have difficulty or are embarrassed to talk about sexual topics, which causes a lack of information or wrong beliefs and attitudes towards this issue, especially among families. The existing studies in Iran have not had a deep and special attention on this issue. Therefore, this study aims to qualitatively investigate the factors affecting the quality of sexual life in Iranian elderly men with andropause. Methods & Materials This is a qualitative study conducted in 2022 using the content analysis method. Using a purposeful sampling method, 14 elderly men with andropause were selected from among those who visited five health centers in different areas of Mashhad city in Iran. Data were collected using a semi-structured interview. Data analysis was done at the same time as sampling by using the conventional content analysis method. MAXQD software was used for data management. Results The mean age of the participants was 70 years. Eight men had primary education, three had middle school education, one had a high school diploma, and two were illiterate. The findings included 290 codes, 19 subcategories, 9 categories, and 3 themes. The themes were perceived sexual impotence, non-sexual feelings and experiences, and the desire to have an active sexual life. Conclusion The result of in-depth interviews with the elderly with andropause showed the components that can be addressed by officials and researchers for facilitating appropriate planning in this area. The knowledge of the existing situation and how the affecting factors can be the basis of new studioes in this field.

Nowadays, the use of supportive and non-pharmacological methods in disease management and empowerment of elderly patients is of increasing importance. This study was aims to assess the effect of a 5A model-based self-management program on self-management ability and dyspnea severity in the elderly with chronic heart failure. Methods & Materials This is a randomized controlled clinical trial that was conducted on 75 eligible elderly people with heart failure (Class II or III) in Babol, Iran. They were randomly divided into two groups of intervention and control. The intervention group received the self-management training program based on the 5A model for 12 weeks. The control group received the usual training. The data before and immediately after the intervention were collected using the self-management ability scale (SMAS) and the five-item modified Medical Research Council (MMRC) dyspnea scale. The collected data was analyzed in SPSS software version 24. Results The mean age of patients was 68.026±3.956 in the intervention group and 69.595±4.079 in the control group. There were no statistically significant differences between the two groups in terms of demographic and clinical characteristics. After the intervention, the total SMAS score and severity of dyspnea in the intervention group were significantly higher than in the control group (P<0.001). The difference was also significant in all subscales of SMAS between the two groups (P<0.001). Conclusion Considering the positive effect of the 5A model-based self-management program on improving self-management ability and reducing the severity of dyspnea in the elderly with chronic heart failure, it can be used as a simple, low-cost, effective method, without the need to go to medical centers, to improve the quality of life of these patients.

Objectives Age stereotypes, as common social beliefs about the aging process and the age groups, can have a considerable impact on the physical and mental health. Considering the lack of a reliable tool in Iran to measure age stereotypes, the present study was aims to investigate the validity and reliability of the Persian version of the age stereotypes questionnaire. Methods & Materials This is a descriptive-cross-sectional study. Participants were 360 elderly people over 60 years old in Kermanshah, Iran, who were selected based on the inclusion criteria using a convenience sampling method. Participants completed the Persian versions of Kornadt and Rothermund’s age stereotypes questionnaire and Kaspar et al.’s awareness of age-related changes (AARC) questionnaire. Data analysis was done using descriptive statistics and confirmatory factor analysis in SPSS software, version 26 and AMOS version 24. The significance level was set at 0.05. Results The mean age of participants was 67.66±5.88 years. Participants were 175(48.6%) males and 185(51.4%) females. In assessing internal consistency, Cronbach’s alpha for the subscale of family and partnership was obtained 0.871; for the friends and acquaintances subscale, 0.842; for religion and spirituality subscale, 0.747; for leisure activities and social or civic commitment subscale, 0.774; for personality and way of living subscale, 0.809; for financial situation and dealing with money-related issues, 0.846; for work and employment subscale, 0.859; and for physical and mental fitness, health and appearance, 0.874. The results of confirmatory factor analysis showed that the eight-factor model had a very good fit. The results of Pearson’s correlation test showed that the subscales of the age stereotypes questionnaire had a positive and significant correlation with the two subscales of the AARC questionnaire. Conclusion The Persian version of the age stereotypes questionnaire has good validity and reliability for older adults. It can be used in future studies in Iran to examine the relationship between age stereotypes and other important variables related to old age.

Objectives Due to the increase in the aged population and the need to improve their health and quality of life, the demand for social services and health care has increased. The present study e aims to investigate the willingness to work with the elderly and the related factors among Iranian dental students. Methods & Materials This descriptive-analytical study was conducted in 2021. The study population consists of all male and female students in dentistry from the Islamic Azad University, Tehran Dental Branch. Of these, 287 were selected by a purposive sampling method. The Willingness to Work with elderly people scale, with 20 items and 4 subscales, was used for data collection. Due to the COVID-19 pandemic, the data was collected online. The collected data were analyzed in SPSS software, version 23 using the independent t-test, multiple linear regression analysis, and one-way analysis of variance. Results The mean age of students was 23.9±3.807 years, and the mean score of willingness was 51.69±13.004. Having the gerontology course did not have a significant effect on increasing the willingness (P>0.05). The willingness level was significantly different in terms of experience working with the elderly, visiting senior care and rehabilitation centers, attending conferences and workshops about gerontology, and voluntary activities (charities) for the elderly (P<0.001). Conclusion The Iranian dental students’ willingness to work with the elderly is not favorable. The students with experience working with the elderly, visiting senior care centers, or attending workshops or conferences on gerontology are more willing to work with the elderly. Therefore, designing educational courses and holding workshops or conferences on gerontology for dental students can be effective in increasing their willingness to work with the elderly.

У роботі до-сліджено механізми підвищення економічної безпеки на основі інноваційних та цифрових перетворень в економіці. Здійснено аналіз впливу цифрових те-хнологій та інновацій на стійкість економічних систем та розвиток підпри-ємств. Робота спрямована на визначення ключових факторів, які сприяють забезпеченню економічної безпеки через технологічні зміни. З початком пов-номасштабного вторгнення на територію України, посилились процеси необ-хідності забезпечення конкурентоспроможності та економічної безпеки. Сут-тєвим методом забезпечення економічної безпеки виступають – інновації, які генерують впровадження новітніх технологій, які у свою чергу створюють умови для збільшення прибутку, можливості випередити інші країни за еко-номічним розвитком, забезпечити економічну незалежність. Функцією дер-жави є забезпечення економічної безпеки, яка полягає у формуванні позитив-ного бізнес-клімату, створенні умов для успішної діяльності підприємств Ук-раїни. Сформульовано основні положення щодо забезпечення економічної безпеки України на основі застосування інноваційних та цифрових техноло-гій та на основі заходів які використовують в Ізраїлі для вирішення даної проблеми.

CVA with wrong-way risk and correlation between defaults: An application to an interest rate swap
Authors: Galisteo Rodríguez Merche , Morillo López Isabel , Preixens Benedicto Teresa
Published: February 2024

This paper presents a counterparty credit risk adjustment model to value over-the-counter financial derivatives. To do so, a bilateral credit valuation adjustment with wrong-way risk (WWR) and dependency between the defaults of both contract parties is developed in line with the Hull-White model (2012), which calculates default probabilities using a hazard rate modelled as an exponential function dependent on the value of the derivative. The model proposed incorporates a modified hazard rate for each entity, which includes the company’s own exposure to credit risk attributable to the other entity’s default. By so doing, a correlation between the respective defaults of the entities party to the financial derivative is added. The model developed is also applied to obtain the fair value of an interest rate swap and the results obtained, using Monte Carlo simulation, demonstrate that the value of this swap adjusted to the credit risk falls when the dependency between the entities’ defaults is considered.

Published: February 2024

Objective: To describe the characteristics of the number of hectares (located in the UMAs registered in the state of Chihuahua) used for the white-tailed deer free-range production, the level of exploitation of the species, and its economic value.
Design/Methodology/Approach: This study determined the number of Units for the Conservation, Management, and Sustainable Use of Wildlife (UMAs) registered in the state of Chihuahua, where white tailed deer had been exploited since 2015. Forty-three municipalities in the state of Chihuahua, with a total of 159 UMAs, were analyzed. Twenty-three randomly selected UMAs were characterized, taking into account the hectares and the presence of white-tailed deer per municipality. Finally, the exploitation value of the species use per community was established in order to determine its exploitation and economic value.
Results: The total area used for the exploitation of the white-tailed deer reaches 1,067,380 hectares. Thirty-two municipalities had potential for the exploitation of white-tailed deer. Thirty-three deer were hunted per season in the 23 UMAs under study, which accounts for a $990,000 Mexican pesos gross income for the state of Chihuahua per season; this exploitation generates a total of 115 temporary jobs for the communities surrounding the 23 UMAs studied. Chihuahua’s UMAs welcome a total of 33 white-tailed deer hunters per season. Hunters pay $30,000 to $34,000 Mexican pesos for each white-tailed deer specimen.
Study Limitations/Implications: The study provides an overview of the current state of the UMAs in the state of Chihuahua that have a permit for the white-tailed deer hunting exploitation. Each of the UMAs under study has specific characteristics, including: the services offered, the associated hunting species, and the exploitation populations under an integrated sustainability arrangement. This study does not include the benefits of exploiting associated species, such as the collared peccary (Dicotyles tajacu) and the wild turkey (Meleagris gallopavo).
Findings/Conclusions: Based on the number of registered UMAs, 32 out of 40 municipalities use 100% of their registered area for the exploitation of white-tailed deer. The white-tailed deer hunting exploitation increases the profitability and productivity of livestock ranches.

Published: February 2024

Objective: To evaluate the morphological and thermo-mechanical properties of a biofilm obtained from orange peel.
Design/methodology/approach: Pectin, a polysaccharide obtained from orange peel, has the potential to be used as a raw material in the bioplastics industry. The samples obtained were characterized by the Scanning Electron Microscopy (SEM) technique, mechanical tension and by thermogravimetric analysis (TGA).
Results: The elastic modulus was in the range of 7.7 to 29.9 MPa, depending on the plasticizer content. The thermogravimetric analysis showed a thermal decomposition between 134.42 to 153.98 °C depending on the plasticizer content and up to five events were identified.
Limitations of the study/implications: During the process, a pectin yield of 75% of orange peel was obtained.
Findings/conclusions: In developing countries such as Mexico, waste originating from agricultural and agro-industrial activities represents an important source of natural carbohydrate polymers that can be used to produce bioplastics, intended to replace petroleum-derived materials. In the case of orange peel, it can become a potential raw material to obtain value-added products in sectors of the food industry. These results indicated that our pectin has suitable properties to be used as raw material for the manufacture of bioplastics.

Objective: In this work, we undertook the task of isolating and identifying Fusarium obtained from papaya fruits grown in the Veracruz region and carried out antibiotic tests to find a beneficial fungus that could exert biological control.
Methodology: Juvenile fruits with necrosis and rot were collected from papaya plants of the Maradol variety, from here the pathogenic fungi were obtained, which were morphologically and molecularly characterized using the ITS gene. Subsequently, the isolated pathogenic fungi were confronted with the Trichoderma sp fungus.
Results: Ten isolates were obtained, of which four were Fusarium solani. From the confrontations, a 66% to 100% percentage of inhibition in these pathogenic fungi was obtained.
Limitations of the study: It is proposed that future evaluations carry out long-term follow-ups to evaluate the persistence and effectiveness of biological control.
Findings/conclusions: Timely identification of pathogens could represent a biological control strategy in disease management programs.

Published: February 2024

Objective: To evaluate the productive behavior of Urochloa hybrids, depending on the regrowth age.
Design/Methodology/Approach: The study was carried out under rainfed conditions during 2018. The Cayman, Mulato II, Convert 330, Cobra, Camello I, and Camello II hybrids were evaluated based on the regrowth age (2, 4, 6, 8, and 10 weeks). The following variables were evaluated: plant height (PH), total dry matter (TDM) yield, dry matter per leaf (DMl) yield, dry matter per stem (DMs) yield, crude protein content (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF). The data obtained were evaluated by means of a randomized complete block design with three repetitions, divided into plots: a large plot for the cultivars and small plot for the regrowth ages.
Results: The Camello II cultivar obtained the highest TDM yields during the sixth and eighth weeks (4.15 and 6.35 t DM ha-1, respectively); however, during the tenth week, the yield was equal to the yield obtained with the Mulato II and Cayman cultivars (p<0.05). The highest DMl yield was obtained by the Mulato II cultivar during the sixth, eighth, and tenth weeks (3.37, 4.56, and 3.86 t DM ha-1, respectively). The Mulato II cultivar recorded the highest CP values during the second and fourth weeks (158 and 126 g kg-1, respectively); however, the Camello II cultivar obtained the highest CP values during the sixth, eighth, and tenth weeks (99, 95, and 87 g kg-1, respectively). The NDF and ADF values increased as the regrowth age increased: in the tenth week, the Camello II and Cobra cultivars obtained the highest NDF values, while the Camello II cultivar recorded the highest ADF value during the same period.
Study Limitations/Implications: Urochloa cultivars were developed for their establishment in humid tropical conditions, where their productive performance is greater. However, in dry tropical conditions, the Cayman, Mulato II, and Cobra cultivars have had a better performance than other grasses —such as buffel grass (Pennisetum ciliare), which is used to feed ruminants. In this sense, other Urochloa cultivars (e.g., Camello I and Camello II), which have greater tolerance to droughts, show desirable forage characteristics, such as yield and forage quality.
Findings/Conclusions: The cultivars with the best productive performance were Camello II, Mulato II, and Cayman.
