Dental Implant Failure in Post-Menopausal Women on Oral Bisphosphonates: A Systematic Review and Meta-Analysis
Authors: Pishan Bahar , Andrukhov Oleh , Rausch-Fan Xiaohui
Published: April 2024

A systematic review was designed to investigate the effect of treatment with oral bisphosphonate (BP) on osseointegration of dental implants and the incidence of BP-related osteonecrosis of the jaw (BRONJ) in postmenopausal women. Multiple electronic databases, including MEDLINE (PubMed), EMBASE, and SCOPUS, were searched to find all eligible articles published since 1990. All titles and abstracts retrieved by searching information sources were evaluated independently by 2 authors against the eligibility criteria. The number of cases ranged from 11 to 235, and the number of controls ranged from 14 to 343. Alendronate was used in all other studies. Risedronate was used in 6 studies, while ibandronate was used in 4 studies. The number of implants in cases ranged from 25 to 1267, while in controls, the number of implants ranged from 28 to 1450. The time between the placement of implant and the follow-up visit ranged from 4–6 months to 8 years. The results show that out of 2582 placed implants, 50 (1.94%) failed in BP-treated patients. This is while out of 4050 placed implants, 188 (4.6%) failed in the non-BP group. The results from the meta-analysis demonstrated that BP therapy is significantly associated with increased implant failure rates (RR = 1.73 [95% CI, 1.03–2.83], P = .04). Overall, the qualitative assessment of this review suggests that oral treatment with BPs in postmenopausal women does not increase the rate of dental implant failure. Thus, further studies with larger sample sizes should compare BP and non-BP groups in regard to dental implants.

Published: April 2024

Early seedling development and germination are vital phases in the life cycle of plants, as optimal germination contributes significantly to crop yields. Selenium (Se), an essential micronutrient for several organisms, including plants, plays a crucial role in improving germination and early seedling growth. Seed priming treatment is presented as a promising alternative to improve these aspects. This study aimed to evaluate the impact of priming treatment with different concentrations of selenium on germination and seedling development of Criollo maize. Two maize varieties were used and five selenium concentrations (0, 25, 50, 75 and 100 µM L-1) were tested. The results indicated that concentrations of 50 and 75 µM L-1 selenium had a noticeable positive effect on variables such as germination percentage, germination rate, germination potential and germination speed index. However, higher concentrations (100 µM L-1) showed consistently lower results, suggesting a negative impact on the germination process and initial seedling development.
HEAT CONVECTION ENHANCEMENT OF UNILATERAL-HEATED SQUARE CHANNELS BY INCLINED RIBS OPTIMIZED BY MACHINE LEARNING
Authors: Wang Xiangyu , Xu Xianghua , Liang Xingang
Published: April 2024

Optimizing structure parameters is pivotal in enhancing convective heat. This study leverages machine
learning methods to establish a relationship between input parameters and targets, providing a novel approach to structure parameter optimization in convective heat transfer of a unilateral-heated square channel with inclined ribs. A substantial dataset is procured through batch modeling and computational fluid dynamics (CFD) simulations by changing the rib structure (length, diameter, and
spacing). The Gaussian process regression is applied to train the surrogate model due to its continuity
and smoothness. Two scenarios are considered: the datum of the best structure from CFD simulation is included or excluded in the training dataset. When the datum from the best CFD structure is included in the training dataset, the optimized Nusselt number and the comprehensive heat transfer characteristic performance evaluation criterion (PEC) from the surrogate model are almost the same with the best
CFD result. When it is excluded, the surrogate model optimization can yield a 7% and 3% increase
in Nu and PEC. The heat transfer mechanism and heat transfer effects of the unilateral-heated square channels with inclined ribs are analyzed. The optimal Nu and PEC under different Reynolds numbers are obtained, and the variation of geometric parameters with the optimal solution is analyzed. This study underscores the potential of machine learning in optimizing convective heat transfer channels,
benefiting future research and applications in this field.
IMPACTS OF USING POROUS CORNER PARTITIONS AND BLADE SHAPED NANOPARTICLES IN BASE FLUID ON THE PERFORMANCE IMPROVEMENT OF THERMOELECTRIC GENERATOR MOUNTED VENTED CAVITIES AND INTERFACE TEMPERATURE ESTIMATION WITH PROPER ORTHOGONAL DECOMPOSITION
Authors: Selimefendigil Fatih , Oztop Hakan Fehmi
Published: April 2024

Numerous technical applications, such as solar power, refrigeration, waste heat recovery, thermal management, and many more, employ thermoelectric devices because of the numerous advantages they offer. Techniques are required to improve their effectiveness in usage. In this study, a unique technique for improving the performance of a thermoelectric generator (TEG) positioned between vented cavities is proposed. The method combines the effects of blade-shaped nanoparticles in the base fluid and corner porous partitions. A numerical study using the finite element method is conducted for different values of Darcy number of upper and lower cavity (10-6 ≤ Da1 ≤ 10-2, 10-6 ≤ Da2 ≤ 10-2), opening ratio (SR between 0.5 and 2.5), and nanoparticle loading amount (SVF between 0 and 0.03). By adjusting the permeability of the partitions and opening ratio of the cavities, significant changes in the flow field can be obtained. TEG power increases with greater opening ratios and lower partition permeabilities. By changing the permeability, the TEG power can increase by up to 27.5 percent, while increasing the opening ratio from SR = 0.5 to SR = 1 can increase the TEG power by up to 140 percent. Using blade-shaped nanoparticles results in additional improvements, with values of 32.7% at SR = 0.5 and 20.26% at SR = 2.5. Using 180 parametric computational fluid dynamics cases, a POD-based low-cost reconstruction model is created for the interface temperatures at the hot and cold sides using five-POD modes. The method may be used for other complicated geometries where 3-D computations are costly and allows for the rapid computation of coupled TEG-vented cavity systems with corner partitions.

Purpose: To investigate the compliance and acceptance of first time using nasal spray OC-01 (Tyrvaya) for dry eye in order to study the potential strategy to improve the usage. Method: Twenty patients with DED either having resistance to eye drops therapy or having difficulty applying eye drops were included from January 2023 to July 4, 2023. A sample of one bottle of Varenicline was given to patients to spray both nasal cavities two times a day for two weeks. Detailed instructions and possible side effects were given according to the pharmaceutical pamphlets. The second bottle was given to those patients who stopped for the first bottle for the second chance to try. Questionnaire consisted of the following questions: 1) In two weeks did you stop the treatment? If you did stop and cannot continue, what was the reason? 2) were your dry eye symptoms being less and you can accept this treatment and continue? 3) How did the second bottle work? Result: Out of 20 patients, 18 responded (90%). 56% had good response with either mild side effect or can tolerate well and experience improvement in dry eye. 44% had poor response with sneezing, cough, nasal irritation resulting in abandoning the nasal spray. The second bottle improved the discontinue rate to 17%and good response rate to 83%. There was 1.1% lost follow up. Conclusion: The first-time successful rate of using nasal spray of Tyrvaya is about 56%. The discontinuation rate was about 44%. Second bottle with further education had better successful rate. The discontinuation rate improved to 17% and the successful rate to 83%. Education and reinforcement may increase the acceptance and compliance for patients who are indicated for the medication.

INTRODUCTION: Telerehabilitation advanced significantly with the emergence of COVID-19 and the recommendation of limiting physiotherapist-patient contact time whenever practicable. The effectiveness of telerehabilitation on those who had a longer stay in hospital and on oxygen support following discharge is still under question. OBJECTIVES: To evaluate the effects after six weeks of pulmonary telerehabilitation on exercise tolerance, fatigue level, perceived exertion, symptoms of depression and quality of life in patients surviving COVID-19. MATERIALS AND METHODS: A quasi-experimental study was conducted on 25 post-COVID-19 patients following discharge in a home environment setting. The participants were advised to prepare equipment such as oxygen concentrator, B-type oxygen cylinder (backup), lengthy oxygen tubes, finger pulse oximeter, mini static pedal exerciser, incentive spirometry, weight cuffs or water bottles and sandbags. After six weeks of telerehabilitation, the patients underwent assessments including initial oxygen saturation (SPO2), heart rate, peak oxygen demand during exercise to maintain baseline SPO2, peak heart rate, maximum drop in SPO2, recovery time to baseline SPO2 measured with a pulse oximeter and stopwatch, peak perceived exertion using the Borg Dyspnea Scale, peak fatigue score using the visual analog scale (VASF), quality of life assessed with the SF-36 questionnaire, and mental health status evaluated with the Hamilton Depression Scale (HAMD). One-way repeated measure ANOVA and paired t-test were used. RESULTS: Significant improvements following the intervention on the initial SPO2 (F (2.12, 23.13) = 21.0, p<0.05) and heart rate (F (1.839, 20.23) = 43.73, p<0.05), peak maximum oxygen demand during exercise to maintain baseline SPO2 (F (1.487, 16.36) = 8.96, p<0.05), peak maximum perceived exertion (F (5, 55) = 112.51, p<0.05), peak maximum fatigue score (F (1.755, 19.30) = 67.44, p<0.05), peak heart rate (F (1.798, 19.78) = 50.99, p<0.05), peak drop in SPO2 (F (2.467, 27.14) = 41.46, p<0.05) and peak recovery time to achieve baseline SPO2 (F (5, 55) = 78.89, p<0.05). Six-week post-analysis on the depressive symptoms (mean difference =11.25, p< 0.05) and quality of life also showed significant improvement (mean difference =29.92, p< 0.05). CONCLUSION: Six weeks of comprehensive pulmonary telerehabilitation with simple equipment improved tolerance to exercise, fatigue, perceived exertion, symptoms of depression and quality of life for post-COVID-19 patients.

Published: April 2024

Markkinaperusteisen kulttuuripolitiikan ja niin sanotun manageriaalisen käänteen vaikutukset taidemaailmoihin ja kulttuuriin Suomessa ovat moninaiset. Siirtymä laajan hyvinvointivaltion kaudelta markkinaperusteisen kulttuuripolitiikan aikakaudelle ei ole tapahtunut ilman kriittistä keskustelua. Artikkelissa selvitetään sitä, minkälaisia diskursiivisia kantoja markkinaperusteiseen kulttuuripolitiikkaan Suomen kuvataiteilijapolitiikassa muodostettiin vuosina 2000–2020. Artikkelin tutkimushypoteesina on, että markkinaperusteinen kulttuuripolitiikka on jakanut taide- ja kulttuurialojen henkilöitä vastakkaisiin leireihin ja että hyvinvointivaltion aikaiset kulttuuripoliittiset painotukset ja modernistinen taidekäsitys – ja näiden myötä korkeataiteen legitimoiminen – ovat osaltaan vaikuttaneet siihen, kuinka markkinaperusteiseen kulttuuripolitiikkaan on suhtauduttu. Markkinaperusteisen kulttuuripolitiikan pyrkimykset on nähty sekä uhkina että mahdollisuuksina Suomen kuvataidekentällä.

Del autopercatamiento corporal a la experiencia de alteridad en el propio cuerpo, el caso de la somatoparafrenia
Authors:   Universidad Nacional Autónoma de México, Garavito Maria-Clara
Published: April 2024

Los pacientes con somatoparafrenia reportan que una extremidad no les pertenece. En filosofía, esta psicopatología motiva la discusión sobre el autopercatamiento, entendido como el sentido de propiedad que acompaña nuestras experiencias mentales. También motiva reflexiones sobre el autopercatamiento corporal; es decir, sobre la experiencia de un miembro como parte del propio cuerpo. Propongo que la somatoparafrenia involucra una dimensión intercorporal anómala. A diferencia de otras patologías de la espacialidad del cuerpo, en la somatoparafrenia se gana alteridad dentro de los límites del cuerpo orgánico: el miembro pertenece a otro. Desarrollo mi propuesta en dos partes: en la primera, retomo discusiones de la filosofía sobre la autopercatamiento corporal usando la somatoparafrenia como ejemplo. En la segunda parte, planteo algunas reflexiones para entender el problema de la alteridad en la somatoparafrenia, y por qué este trastorno puede ubicarse dentro de las discusiones actuales sobre las vivencias intercorporales.

Authors: Dianov Maksim P. , Kyzlasov Pavel S. , Martov Aleksey G.
Published: April 2024

BACKGROUND: The cause of ejaculatory dysfunction in patients with benign prostatic hyperplasia can be either the disease itself or its surgical or drug treatment, including the use of alpha1-blockers.
AIM: To study the effect of alpha1-blockers on the ejaculatory function of patients with benign prostatic hyperplasia.
MATERIALS AND METHODS: Under observation were 90 patients with benign prostatic hyperplasia aged from 56 to 79 years, who were distributed into 3 groups of 30 people. Patients of the group 1 were prescribed tamsulosin at a dose of 0.4 mg once a day, patients of the group 2 were prescribed silodosin at a dose of 8 mg once a day, and patients of the group 3 were prescribed alfuzosin 10 mg once a day. Duration of treatment is 4 weeks. To assess the effectiveness of treatment and its impact on copulatory function before and after treatment, patients filled out the IPSS, IIEF-5, ICF and MSHQ questionnaires.
RESULTS: The reduction in the severity of clinical manifestations of benign prostatic hyperplasia and the improvement in quality of life in patients of the three groups were the same. The effect of alpha1-blockers on erectile function has not been noted. A significant decrease in ejaculatory function was revealed in patients of the groups 1 and 2, while in patients of the group 3 no changes in ejaculatory function were observed.
CONCLUSIONS: When planning drug therapy for patients with benign prostatic hyperplasia, it is necessary to take into account the specific effects of different alpha1-blockers on ejaculatory function.

Authors: Rodionova Svetlana S. , Asi Habiballah Zaid A. , Krivova Alla V. , Murtazina Elmira M.
Published: April 2024

BACKGROUND: Age and comorbidities are considered independent preoperative predictors of mortality in proximal femoral fractures; however, their contribution remains debatable.
AIM: To assess the prognostic significance of age and Charlson Comorbidity Index (CCI) of the survival of older people with proximal femoral fractures.
MATERIALS AND METHODS: This retrospective prospective study included all cases of proximal femoral fractures that occurred between January 1, 2019, and December 31, 2019, in individuals over 50 years of age from the cities of Tver, Torzhok, Rzhev, VyshnyVolochek, and Kashin. ICD-10 codes: S72.0, S72.1, and S72.2. The CCI of each patient was calculated using an online calculator and clinical data obtained from patient and outpatient records. Statistical analysis. Survival was estimated using Kaplan–Meier curves and the average number of deaths per day per 1000 people. The follow-up interval was obtained in days from the time of injury to the event of death or last contact with the patient. The minimum observation period was 876 days, and the maximum was 1492 days.
RESULTS: The survival rate of patients decreased from younger to older age groups, both among those operated on and those who were not. Patients aged ≥85 years were at greatest risk (median survival: 257 days; 95% CI: 36.6–478.3). CCI was significantly associated with survival: the risk of death with CCI 3 was 3–6 times higher than that with CCI 2–3, depending on the follow-up interval. CCI reflected health status more than age: within the same age group, there were patients with different CCIs.
CONCLUSION: Using age and CCI simultaneously as predictors of mortality and more accurate indicators of health status will enable the planning of the utilization of additional medical and social resources in the preoperative and postoperative periods, thereby increasing survival.
Comparison of Near-Surface Attenuation from Surface Array-Based Seismic Noise Data and Borehole Weak-Motion Recordings at the STIN Test Site in Northeastern Italy
Authors: Dreossi Ilaria , Parolai Stefano
Published: April 2024

Seismic wave attenuation and the related shear-wave quality factor (QS) in the near surface are crucial parameters for ground motion simulations and seismic hazard assessments. Although recent approaches developed to calculate QS from seismic noise acquired by surface arrays have been accepted for practice, additional testing and comparison of results estimated using various geophysical methods are still necessary to verify the reliability of such techniques. This work presents the results of an experiment conducted at the STIN site in northeastern Italy, which is equipped with a 100 m deep instrumented borehole. A seismic noise campaign was implemented by installing a temporary independent local surface array of seismological stations. The gathered data were used to initially estimate the shear-wave velocity (VS) profile and frequency-dependent Rayleigh-wave attenuation, and subsequently determine the QS factor via a linearized inversion method. The study compares these findings with the VS and QS values derived from analyzing weak-motion events recorded by two permanent seismic sensors positioned at the top and bottom of the well. The results confirm the potential of the inversion procedure used to obtain QS from local-scale seismic noise arrays as a promising approach for conducting attenuation studies at the local level in less geologically complex sites.

The effect of listening to Holy Quran recitation on stress among healthy adults: a non-blinded randomized controlled trial
Authors: Hanafi Muchtar , Rahmatillah Arif , Wiyono Nanang , Mirawati Diah Kurnia
Published: April 2024

BackgroundStress is the body’s inability to reach a balance between physical or psychological demands and the ability to meet them. Failure to meet these demands has a crucial impact which includes physical, emotional, and behavioral disorders. Recitation of the Quran is believed to cause relaxation by lowering adrenocorticotropic and cortisol hormonal levels. This study aimed to assess the effects of Quran recitation on stress levels using the biofeedback indicators electromyogram, skin conductance, and heart rate among healthy adults.
MethodsThis study used a pre- and post-test group design involving 40 males between 19 and 23 years of age, randomized into two groups, i.e. control group (n=20) and Quran recitation listeners (n=20). The subjects were conditioned in a quiet room for 30 minutes before the stress level measurements were taken. The stress level measurements by means of electromyogram, skin conductance, and heart rate were performed with biofeedback before and after giving the stressor tests’ protocol. Statistical analysis using independent t-test was then performed.
ResultsThe baseline comparative measurement using biofeedback between control and treatment groups revealed nonsignificant between-group differences in electromyogram, skin conductance, and heart rate (p=0.150; p= 0.389; and p=0.985 respectively). After applying the stress protocol followed by the intervention, the independent t-test revealed significant between-group differences in electromyogram and skin conductance (p= 0.042 and p=0.030), but not in heart rate (p=0.741).
ConclusionsOur study demonstrated that Quran recitation has a significant effect in relieving stress levels assessed using biofeedback parameters (electromyogram and skin conductance) among healthy adults.

Detection of HIV Using Saliva
Authors: Arinawati Dian Yosi
Published: April 2024

Saliva is a biofluid that is secreted by both the major and minor salivary glands in the oral cavity. It is a crucial component in the digestive process and plays a vital role in maintaining oral health. This fluid is commonly referred to as mirror biofluid, as it indicates the current pathophysiological state of the human body. Over the past decade, saliva has been widely utilized as a diagnostic tool for detecting both oral and systemic diseases. Its non-invasive nature and ease of collection make it an attractive option for healthcare professionals. Saliva is an easily collectible, non-invasive, and safe material that can be utilized as a valuable medium for detecting infectious diseases. The objective of this literature review is to assess the efficacy of oral fluid testing as a diagnostic tool for the detection of HIV. A comprehensive literature review was conducted utilizing PubMed databases, focusing on English language articles and relevant keywords. Saliva-based biomarkers have proven to be an effective means of diagnosing and tracking the progression of HIV, as well as monitoring the efficacy of treatments. This is a significant advancement in the field of HIV research and has the potential to significantly improve patient outcomes

Background: The negative meaning and rumours associated with the conduct of clinical trials regarding their experimental nature adversely affect trust and their conduct. A typical example of the challenges in conducting clinical trial studies was where Ghana was selected to conduct the ebola vaccine trials, which was not successful. This study explored the social and political perspectives on the unsuccessful implementation of the ebola vaccine trial in Ghana.
Methods: This was a cross-sectional exploratory study using qualitative research approach where 31 in-depth individual interviews and Key informant interviews were conducted with participants. The interviews were recorded, transcribed and coded into themes using Nvivo 12 software to aid thematic content analysis.
Results: The views expressed by participants suggested that lack of stakeholder engagement to create awareness on the Ebola vaccine trial led to doubts on the purpose for the trial. Also, media propaganda, negative influence and the perception that conducting the vaccine trial in Ghana could introduce the Ebola virus into the country created panic and fear, which affected public trust and support for the Ebola vaccine trial conduct in Ghana. Furthermore, political influence linked with site selection and timing for the study in particular, led to mistrust and the subsequent suspension of the trial in Ghana.
Conclusions: Based on the interpretation of our data, we conclude that the indefinite suspension of the Ebola vaccine trial in Ghana could largely be attributed to both fear and political influence as well as misinformation resulting from media propaganda leading to mistrust.

Anagen effluvium is a type of hair loss that results from a sudden decrease in the metabolic activity of the hair follicle’s matrix cells. The condition is commonly associated with cancer treatments such as chemotherapy and radiation, but can also be caused by other factors. Plica neuropathica, on the other hand, is a condition where hair on the scalp becomes irreversibly matted. It is often linked to psychiatric disturbances, poor hair care, scalp infestations, and the use of ionic surfactants in shampoos. In rare cases, it has also been associated with certain medications. Here we present a rare case of a 16-year-old female who was on azathioprine and was diagnosed with an overlap of both conditions.

In this paper, we are interested in the prediction of flank wear through dry hard turning of AISI D2 steel with a mixed alumina insert. In the machining process, the cutting tool is principally affected by two kinds of wear: flank and crater wear. The latter are criteria for cessation of the tool function. In the absence of a real-time wear sensor, it is necessary to know or track wear with the view to prevent tool damage.
For this purpose, the current research focuses on the development of predictive models of flank wear based on Artificial Neural Network (ANN), Gaussian Process Regression (GPR), Support Vector Machine (SVM), and Polynomial Fit using Genetic Algorithm (GAPOLYFITN).
The simulation process involves considering input variables including feed (f), cutting speed (Vc), and cutting time (tc); the output is the flank wear (VB). To assess the statistical efficacy of the predictive models, some performance indicators were employed, including the R-squared statistic-R2, Mean Square Error-MSE, Mean Absolute Error-MAE, and Mean Absolute Percentage Error-MAPE.
The results, for the present case study, show that the R-squared statistic ranges from 0.85 to 0.99, the MSE is between 0.000046 and 0.000177, the MAE ranges from 0.002958 to 0.009336, and the value of MAPE varies from 3.50 to 9.60%. The predictive capability of GPR and GAPOLYFITN in determining flank wear are the best, as they exhibit high (R2), and lower values of MSE, MAE, and MAPE. The powerful predictive model of flank wear is the GPR because it provides R2 = 0.96, MSE = 4.6e-5, MAE = 0.002958, and MAPE = 3.50%.

挤出设备的工艺效率和能耗问题成为制约聚合物挤出行业发展的关键挑战。本文提出了一种全新的聚合物场协同原理，用以指导解决传统挤出设备混合效率和能源利用效率低的问题。文章对Maddock结构、主副螺纹结构、销钉结构、波状结构四种新型非常规螺杆结构进行了有限元分析，并与传统的单螺杆进行了比较。结果表明，新型非常规螺杆流道中产生了更复杂的熔体流动模式，增强了拉伸变形或螺旋流动。在熔体挤出过程中，不同程度的拉伸或螺旋流动提高了混合和热传输效率。其中Maddock元件诱导的螺旋流对流场中的拉伸塑性变形影响最大，同时螺旋流引起了流道内熔体的径向运动，极大地促进了速度场、速度梯度场和温度梯度场之间的协同作用。拉伸或螺旋流动提高了螺杆流道内的径向热量和质量传输效率，从而提高了设备的整体工艺效率。有限元分析的结果证实了聚合物场协同原理的科学性。
A Short Venture into Protest: Anti-War Protests at TCU, 1960-1973
Authors: Lucido Anthony
Published: April 2024

Past historians have analyzed the 1960s American student antiwar movement mainly through a northern or western lens, focusing on particular hotspots and violent confrontations like Berkely and Columbia. This paper will add to the literature by analyzing antiwar protests on a relatively small, lesser-known college on the edges of the South, Texas Christian University. For despite its small size and failure to achieve tangible results, the TCU peace movement consisted of passionate organizers who utilized uniquely Southern styles of activism to raise awareness for their cause. Constantly attacked by administrative systems, fellow students, and biased publications, student organizations like Students For Peace, the Vietnam Moratorium, and Spunk Magazine brought the war to TCU, eventually pulled the student body out of years of political apathy, slowly changed public opinion, and inspired liberal reforms in school policy.
History of Cuba
Authors: Johnson Jacora
Published: April 2024

For the overall aesthetics of the piece, I decided that each silhouette would take the form of a mask so each design would help portray the experiences lived by Black Cubans. I explored the racialized experiences of Black Cubans through the three eras of the Pre/Colonial (1500-1898), Neocolonial (1899-1959), and Revolutionary (1959-Today) periods throughout Cuban history. I attempted to balance the impact of racism and inequity between experiences and cultural significance within my designs. My decision to have a minimal background outside of the masks comes from our time watching the “Black in Cuba” documentary, participants, academics, and everyday non-Black Cubans continued to conflate the experiences of Black Cubans with those of People of Color, and despite the masks portraying this specific racialized experience, I wanted the background to further the idea that this a Black experience.
Examining Parental Alcohol Use and Peer Relationships as Predictors of Substance Use Severity
Authors: Inaganti Vinisha
Published: April 2024

In the United States, issues with substance use among adolescents has grown in its prevalence, and past research has shown a continuity in substance use amongst children with substance involved parents. In adolescence, young men tend to report higher rates of alcohol use when compared to young women. As such, we were interested in examining gender as a moderating factor on the relationship between parental alcohol use and substance use severity. Amazon’s MTurk was used to recruit 185 participants with a history of substance use to complete a series of surveys. Participants reported parental alcohol use during childhood and involvement with pro-social peers. Results revealed gender did not moderate the relationship between parental substance use and respondents’ self-reported substance use. However, there were strong correlations among substance use severity, parental alcohol use, and involvement with pro-social peers. Specifically, respondents who were the child of a mother who experienced problems with alcohol were 3.12 times more likely to have a severe SUD. This effect was not observed when paternal alcohol use was examined as a predictor of substance use severity (p=0.651). Respondents involved with pro-social peers are less likely to have a severe substance use disorder (p<0.001). Together, children whose mothers struggled with alcohol use were more likely to develop a severe substance use disorder. In contrast, having a father who struggled with alcohol use did not affect respondents’ involvement with substance use. Furthermore, having a peer support system reduces subsequent substance use, regardless of parental alcohol use.
Blood Biomarker and Physical Activity Correlations in Persons with Parkinson’s Disease
Authors: Morales Julia
Published: April 2024

Parkinson’s disease (PD) is a debilitating disease that reduces an individual’s quality of life (QOL). PD has a complex pathophysiology, but inflammation is a major contributor. Inflammation is a biological process that removes harmful stimuli and initiates the healing cascade. Researchers commonly use inflammatory markers, such as tumor necrosis factor-alpha (TNFα),interferon-gamma (IFNγ), and interleukin 1-beta (IL1β), to study PD pathologies. While PD is irreversible, physical activity is a non-pharmacological treatment exhibiting beneficial outcomes related to PD and inflammation. To determine if exercise frequency affects the quality of life (QOL) and the magnitude of change in inflammatorybiomarkers associated with PD. Researchers recruited 10 individuals diagnosed with PD to participate in a cross-sectional study. Participants completed four questionnaires to determine their current physical activity (PA) level and QOL. Blood samples were analyzed to determine differences in serum TNFα, IFNγ, and IL1β concentrations between different PA levels of persons with PD. With an alpha level of 0.05, this project only yielded two significant results: an unexpected positive relationship between IL1β and PA level and an expected negative relationship between IL1β and QOL. Although they were not significant, several results trended in the expected directions. Discussion: Observed trends indicated that increasing physical activity decreases inflammatory blood biomarker levels and increases QOL while increasing sedentary behavior increases inflammatory blood biomarker levels and decreases QOL.
