Hidden in Plain Sight: The Culture of Excellent Black High Schools in the Era of Jim Crow
Authors: Davis Rosemary A. , Horton Gwendolyn J. , Robinson Dwan V. , Johnsen Susan K.
Published: November 2023

This article describes the cultural characteristics of four elite African American high schools, initiated prior to Brown v. Board of Education, that produced outstanding graduates. Positive school culture characteristics examined were leadership, faculty, curriculum and instruction, student qualities, the environment, and internal and external relationships. The authors posed questions investigating how educators and alumni of Gary, Indiana’s Theodore Roosevelt High School viewed the characteristics of its culture and how the culture compared to other elite African American high schools in the extant literature. Using surveys, archival information, and the research literature, the authors collected information describing the high school’s distinctive features. Comparing the results of Rooseveltwith the other exemplary high school cultures of Dunbar, Sumner, and Terrell, they reported these insights about their cultural characteristics: (a) high caliber and sustained leadership of individuals who cultivated positive school environments and created institutions that were a distinctive blend of school and community; (b) highly educated and qualified faculty members; (c) a rigorous and challenging curriculum emphasizing the preparation of students for higher education; (d) students who exhibited a strong sense of self-esteem, self-efficacy, and a rejection of the concept of inferiority; (e) a family-like environment that was welcoming, inclusive, and receptive to individuals from varied backgrounds that fostered a strong sense of pride and efficacy; and (f) a family climate experienced by internal and external stakeholders that created a sense of belonging and place.
Ageism, a Remarkable Election, and the Journalism Objectivity Norm
Authors: Chen Khin Wee , Lewis Norman P. , Altourah Albaraa F.
Published: November 2023

Age, rarely examined in journalism studies, became salient in 2018 in Malaysia when a 92-year-old, Mahathir Mohamad, unexpectedly became the world’s oldest elected head of state, and he named a 25-year-old, Syed Saddiq, to his cabinet. A content analysis of 1,376 stories published worldwide revealed that journalists treated the ages of the two men infrequently, similarly, and cautiously. Variance occurred with Hofstede’s collectivism-individualism dimension of the publications’ national bases, and in the application of descriptive adjectives, which changed with the election. Overall, the judicious treatment of age shows support for the journalistic objectivity norm.

Published: November 2023

This study investigated the Turkish validity and reliability of the Healing After Gender-based Violence Scale (GBV-Heal) and the relationship between social support perception, posttraumatic growth in university students who are victims of gender-based violence. The study sample consisted of 167 female students who experienced gender-based violence. The Turkish version of GBV-Heal of Kaiser-Meyer-Olkin value was 0.892; the Bartlett Sphericity Test result was determined as χ2  =  195,053, and the obtained variables were found suitable for factor analysis. Perception of social support related to post-violence healing in female university students is effective on posttraumatic growth.
Identification of Relationships Among Resilience Factors Using Network Analysis: A Pilot Study
Authors: Niitsu Kosuke , Lee Chiyoung , Rice Michael J.
Published: November 2023

BACKGROUND:

Although college life can be fulfilling, it can be stressful, particularly for health professional students. In addition, they may have had Adverse Childhood Experience (ACE) that increases their sensitivity to academic stress. Yet, students need to overcome challenges to become successful professionals. The literature suggests the following factors may be associated with resilience: ACE and academic stress as the antecedents; ego-resilience, emotion regulation, resources, social support, inflammatory markers, and genes as the defining attributes; and mental health and sense of coherence (SOC) as the consequences.

AIMS:

The purpose is to identify the relationships among factors associated with resilience using network analysis.

METHODS:

A total of 70 college students participated in this cross-sectional pilot study. They completed measures of psychosocial variables and provided saliva samples, which were analyzed for Serotonin Transporter-Linked Promoter Region (5-HTTLPR)/rs25531 and inflammatory markers. Mixed graphical models including all variables were estimated using the R-package mgm.

RESULTS:

Network analysis revealed positive associations between (1) mental health and SOC; (2) mental health and resources; (3) mental health and social support; (4) SOC and reappraisal of emotion regulation; (5) resources and reappraisal of emotion regulation; and (6) resources and social support. In addition, SOC and academic stress were negatively associated. Furthermore, the short variant of 5-HTTLPR/rs25531 was associated with stronger suppression of emotion regulation and fewer resources compared with the long variant.

CONCLUSION:

Resilience may be influenced by biopsychosocial factors, notably SOC and 5-HTTLPR/rs25531. However, longitudinal research is needed with a larger sample size to better understand how these and other factors may affect resilience.
Cannabinoid hyperemesis syndrome: prevalence and management in an era of cannabis legalization
Authors: Stubbs Justin Joe , McCallum Richard
Published: November 2023

As more states legalize cannabinoid products for recreational use and medicinal purposes, the prevalence of cannabinoid hyperemesis syndrome has become increasingly common. Yet, it remains unrecognized to many healthcare providers along with the most efficacious treatments. Cannabinoid hyperemesis syndrome most often presents with episodic vomiting secondary to chronic daily cannabis use over several months to years. Patients often complain of nausea and abdominal pain that is improved by taking hot showers or baths. Symptoms are alleviated with the cessation of cannabis use over a period of 6–12 months. Treatment for acute attacks often consists of parenteral benzodiazepines in the inpatient setting. Long-term management and prevention of further attacks are aided by tricyclic antidepressants such as amitriptyline with a dose range of 50–200 mg/d. Once a patient is in remission, amitriptyline can be tapered slowly. As cannabis becomes more widely available and accepted in the continental United States, so must education on the diagnosis of cannabinoid hyperemesis syndrome and treatment strategies.
Varieties of Time in Business Sustainability Research: An Integrative Review and Research Agenda
Authors: Morales-Raya Matilde , Muñoz Pablo
Published: November 2023

In this article, we tackle the lack of clarity in the conceptualization and substantive use of time in business sustainability research. We do so by means of an integrative review that synthesizes 172 papers published over the last 20 years across seven subject areas within business and management research. From our review, we developed a typology that highlights three primary categories that differentiate various conceptualizations and uses of time in business sustainability literature: (a) temporal resourcing, (b) temporal structuring, and (c) temporal prospecting for sustainability. The typology organizes a body of literature that remains scattered, provides conceptual clarity, and opens avenues for future empirical research and theorization in the space.
Efficacy and Tolerability of Semaglutide in Patients With Type-2 Diabetes Mellitus: Experience of a Tertiary Care Hospital, Pakistan
Authors: Wajid Maria , Sattar Saadia , Khalid Farah , Masood Muhammad Qamar
Published: November 2023

Background:

Semaglutide, a Glucagon-like peptide 1 (GLP-1) is highly effective as an anti-diabetic medication along with additional benefits of significant reduction in cardiovascular events and weight.

Objectives:

There is a lack of reliable evidence confirming the benefits of Semaglutide in the Pakistani cohort. Our study aims to ascertain the efficacy of Semaglutide in the Pakistani cohort and patient satisfaction.

Methods:

An ambi-directional cohort study was conducted from August 2022 to January 2023 at The Aga Khan University Hospital, Karachi, Pakistan. A chart review was done for all patients with Type 2 diabetes who were prescribed Semaglutide, and baseline data was recorded. Patients were followed prospectively in the endocrinology clinics after at least 3 months for the change in HbA1c, BMI, adverse effects profile, treatment satisfaction questionnaire for medications (TSQM-9) and medication effect score. Mean + STD or median with IQR were computed for continuous data, while categorical variables and percentages were measured. The association between variables was assessed by applying the chi-square test.

Results:

A total of 112 patients were recruited who took the medication for at least 3 months. The mean age of the patients was 50.9 ± 10.5 years with 51.2% females. The mean difference in weight, body mass index, fasting blood glucose, HbA1c, and medication effect score were decreasing from baseline to follow-up (−4.0 kg, −1.5 kg/m2, −23.1 mg/dl, −1.2%, −0.4) respectively. A decrease in appetite was reported in 72.7% of the participants. The major adverse effects observed were dyspepsia (21.4%) followed by nausea (20.5%) and constipation (19.6%). Medication was discontinued in 9.8% of patients due to gastrointestinal side effects. The majority (72.3%) of patients were satisfied with their medication.

Conclusion:

Semaglutide is effective in reducing HbA1c and weight in Pakistani population with measurable tolerability and patient satisfaction.
A Missing Piece in the Puzzle: Exploring the Phenomenon of Suicide Recovery in Developing a Recovery-Focused Suicide Management Program
Authors: Bautista Angelie D. , Reyes Marc Eric S. , Delariarte Clarissa F.
Published: November 2023

The primary aim of suicidology is to understand the phenomenon of suicide by increasing its predictability and prevention to reduce the suicide rate. However, the rate of suicide remained obstinately high. This phenomenological study explored the different perspectives of 5 suicide attempt survivors and 7 mental health professionals on suicide recovery and its process. Phenomenological methods were used to analyze the participants' lived experiences through reduction, description, and finding the essence. Four essential emergent elements elucidate these perspectives, implying the general status of the current suicide healthcare system, vital in understanding suicide and suicide recovery, namely: (1) contextual elements: factors that describe how the participants view suicidality and suicide recovery; (2) facilitative elements: elements that lead to and affect the youths' suicide recovery; (3) impeding elements: factors that hinder suicide recovery; and (4) procedural elements: conditions that pertain to the steps in suicide management and intervention program. By integrating the findings of this current phenomenological study with the Inflorescence Model of Suicide Recovery, a suicide recovery-focused paradigm for suicide care and management was conceptualized. Exploring suicide recovery and its process found that there are different perspectives on suicide among suicide attempt survivors and mental health professionals; thereby, showing the gaps or cracks that exist in the health care system. This fragmentation results in deaths of suicide despite psychological and psychiatric treatments. Thus, the findings were used to conceptualize the Inflorescence Suicide Management Program (ISMP) that hopes to contribute to establishing a structured, systemic, and collaborative health care system.

Authors: Sbragia Elvira , Boffa Giacomo , Varaldo Riccardo , Raiola Anna Maria , Ghiso Anna , Gambella Massimiliano , Benedetti Luana , Angelucci Emanuele , Inglese Matilde
Published: November 2023

Background:

Although myelin-oligodendrocyte-glycoprotein (MOG)–antibody-associated disease (MOGAD) has been considered a more favorable demyelinating central nervous system disorder, recent data evidence that some patients might experience severe relapses and high disability. Actual treatment-options are acquired mostly from anti-aquaporin-4-antibody-positive neuromyelitis optica spectrum disorder and rely on clinical experience. Therefore, treatment of aggressive forms of MOGAD can be challenging.

Objectives and methods:

To describe a patient with an aggressive MOGAD treated with autologous hematopoietic stem cell transplantation (aHSCT).

Results:

A 56-year-old man was diagnosed with MOGAD in 2017 because of right optic-neuritis and anti-MOG-antibody positivity. In the following 2 years, he experienced two optic neuritis with good recovery after high-dose steroid. At the end of 2019, he presented sensory and motor impairment at lower limbs with evidence of several spinal, longitudinally extended, tumefactive inflammatory lesions. Despite sequential treatment with rituximab and tocilizumab alongside high-dose steroid, intravenous immunoglobulins and plasma-exchange, he experienced several clinical relapses and exhibited persistent magnetic resonance activity. He was finally addressed to intense immunosuppression with myeloablative conditioning regimen followed by autologous hematopoietic stem cell transplantation (aHSCT). After 2 years follow-up, he is free from disease-activity.

Conclusions:

In a patient affected by aggressive, treatment-refractory MOGAD, aHSCT resulted as safe and was able to suppress disease-activity for over 2 years.
Hidden figures: how legal experts influence the design of international institutions
Authors: De Silva Nicole , Holthoefer Anne
Published: November 2023

Whose preferences influence the design of international institutions? Scholarship on the legalization of international politics and creation of international legal institutions largely adopts a state-centric perspective. Existing accounts, however, fail to recognize how states often delegate authority over institutional design tasks to independent legal experts whose preferences may diverge from those of states. We develop a principal–agent (PA) framework for theorizing relations between states (collective principals) and legal actors (agents) in the design process, and for explaining how legal actors influence the design of international institutions. The legal dimensions of the PA relationship increase the likelihood of preference divergence between the collective principal and the agent, but also create conditions that enable the agent to opportunistically advance its own design preferences. We argue that the more information on states’ preferences the agent has, the more effectively it can exploit its legal expertise to strategically select and justify design choices that maximize its own preferences and the likelihood of states’ acceptance. Our analysis of two cases of delegated institutional design concerning international criminal law at the United Nations and the African Union supports our theoretical expectations. Extensive archival and interview data elucidate how agents’ variable information on states’ preferences affects their ability to effectively advance their design preferences. Our theory reveals how independent legal experts with delegated authority over design tasks influence institutional design processes and outcomes, which has practical and normative implications for the legalization of international politics.
Social equality and the conditional justifiability of political inequality
Authors: Kobayashi Takuto
Published: November 2023

Social or relational egalitarians try to defend democracy non-instrumentally as a constitutive element of a society where no one stands as inferior or superior to anyone else. However, they face an instrumentalist challenge from within: Why not uphold a non-democratic regime if it outperforms democracy in protecting or promoting egalitarian social relations, for example, by stably producing substantive political decisions that guard against social hierarchies? This article explores the best response to this challenge from the social egalitarian non-instrumentalist standpoint. It argues that the instrumentalist challenge can be accommodated without abandoning the essential non-instrumentalist commitment to democracy; while a nondemocratic regime may be justified under less-than-ideal circumstances as a contingently effective means to realize more social equality, democracy can nevertheless be viewed as a necessary condition for the realization of full social equality.

Published: November 2023

Introduction

Providing integrated and evidence-based support to individuals and families following a diagnosis of dementia is essential in order to optimise their quality of life and assist them to live well. Memory clinics provide multidisciplinary services specialising in the assessment and post-diagnostic treatment of people with dementia. This study sought to identify current practices, barriers and facilitators to provision of postdiagnostic support and to obtain health professionals’ opinion of ideal post-diagnostic support to be offered in Australian memory clinics.

Methodology

This was a cross-sectional qualitative exploratory study. Data was collected from health professionals familiar with the process of diagnosis and post-diagnostic support through two expert panel meetings ( n = 22). In addition, 5 focus groups ( n = 22) were conducted including health professionals who are employed in Australian memory clinics. Data was collected between October 2020 and November 2021. Reflexive thematic analysis was undertaken.

Results

Seven themes and three subthemes were identified under the three topics: Current Practices, Barriers and Facilitators, and Desirable Support. Themes relating to Current Practices were: Tailored Communication and feedback about diagnosis; Prescription of medications and follow-up; and Referrals to health and community services. Themes relating to Barriers and Facilitators were: The structure of the current system; Lack of funding; Lack of resources; Call for government investment. Themes relating to Desirable support were: A key/single point of support; Cognitive interventions; and Counselling and education.

Conclusion

Post-diagnostic support in Australian memory clinics focused primarily on ensuring people understood their diagnosis, information about postdiagnostic support was provided, and dementia medications were prescribed. There were notable differences in practices in metropolitan compared to regional areas. A key concern was the need for increased funding, particularly to support the establishment of a single point of contact to facilitate continuity of care.
Wind turbine gearbox fault diagnosis via adaptive IMFogram
Authors: Yi Cancan , Zhang Fuqi , Huang Tao , Xiao Han , Qin Bo
Published: November 2023

Wind turbines usually operate in mountainous, offshore and other field environments. As the wind speed is constantly changing, the gearboxes of wind turbines operate under variable operating conditions, resulting in a non-stationery and time-varying signal characteristic. For existing time–frequency analysis (TFA) methods, they undergo low time–frequency energy concentration as well as noise interference during the fault feature extraction. IMFogram, a recently proposed time–frequency representation (TFR) method, calculates local frequency and amplitude information of signals based on fast iterative filtering (FIF). Moreover, it is able to remove uncertainty on the time–frequency plane, allowing a long enough time window to reduce the local boundary effects associated with the signal decomposition methods. Therefore, it has potential advantages for TFA. However, the actual performance of IMFogram calculation largely depends on the decomposition effect provided by FIF and the selection of model parameters. With the purpose of obtaining a more distinct and focused TFR of the wind turbine vibration signal, a novel TFA method, namely Adaptive IMFogram (AIMFogram), is proposed in this paper. Firstly, a range of intrinsic mode functions (IMFs) are gained after the decomposition of vibration signals using an improved variational nonlinear chirp mode decomposition, which is treated as the input to AIMFogram to solve the unsatisfied result by traditional FIF under strong noise. Secondly, Renyi entropy-based particle swarm optimization is conducted to perform adaptive parameter optimization of the AIMFogram. Later, using the optimal parameter, the proposed AIMFogram achieves a high-resolution TFR of complex multi-component vibration signals. To verify whether the proposed AIMFogram is effective or not, the method was successfully employed to the fault diagnosis of the rolling bearing in an experimental bench and the gearbox in a 850-kW wind turbine.

Published: November 2023

Plate-like structures, including composite material plates, are extensively employed in major engineering structures such as aerospace, high-speed rail, and civil engineering. The growing utilization of curved panel structures and the increasing complexity of these structures have emphasized the need for flexible sensors capable of efficient signal front-end reception. Addressing the limitations of conventional sensors made of brittle piezoelectric materials in adhering to the surface of structures for health monitoring, a self-developed flexible dielectric elastomer-interdigital transducer (DE-IDT) array is employed to achieve damage imaging in isotropic aluminum curved panel structures and orthotropic composite material plates using linear frequency modulation (chirp) signal excitation. In addition, a proposed fusion method is utilized to obtain weighted imaging results, and evaluation and analysis are performed using relevant indicators. Experimental findings highlight the improved imaging accuracy achieved through phased array data fusion using the linear chirp signal, attributed to its wideband characteristics and ability to capture more damage signals. Moreover, the effectiveness of the circular DE-IDT array for damage detection and imaging in curved panel structures and composite material plates is successfully verified.
Mechanical, morphological, and dimensional properties of heat-treated fused deposition modeling printed polymeric matrix of polyethylene terephthalate glycol
Authors: Kumar Sudhir , Singh Inderjeet , Kumar Dinesh , Mago Jonty , Koloor S S R
Published: November 2023

This study investigates the impact of heat treatment on the mechanical, morphological, and dimensional properties of polyethylene terephthalate glycol (PETG), a commonly used thermoplastic in 3D printing. Taguchi L25 orthogonal array (OA) was employed to optimize 3D printing parameters, considering factors such as infill percentage (ranging from 20% to 100%), layer height (0.12 mm to 0.28 mm), layer width (0.32 mm to 0.62 mm), and infill pattern. Following ASTM D638 type IV standards, mechanical testing revealed that the optimal printing conditions included a 100% infill percentage, a layer height of 0.16 mm, a layer width of 0.32 mm, and an infill pattern of 5. Specimen 22, produced under these conditions, exhibited a notable stress-bearing capacity of 46.43 ± 1.394 MPa. These results are consistent with previous studies that underscored the significance of high infill percentages and finer layer dimensions in enhancing tensile properties. Subsequently, these optimized specimens were exposed to various heat treatment conditions. It was discovered that heat treatment at 85°C for 15 min yielded the most significant improvements, increasing the stress-bearing capacity to 53.462 ± 1.604 MPa, representing an impressive ∼16% enhancement compared to non-heat-treated specimens. However, this treatment also led to increased brittleness. Morphological analysis using Scanning Electron Microscopy (SEM) further substantiated the findings. Specimens subjected to heat treatment at 85°C exhibited fewer voids and porosities than those printed with lower infill percentages and larger layer dimensions. These observations underscored the importance of adequate infill density and finer printing details for optimizing strength. Regarding dimensional stability, dimensional changes were meticulously measured after heat treatment. Notably, specimens subjected to heat treatment at or near the glass transition temperature (Tg) of PETG experienced the most significant shrinkage. Specimen 6, treated at 85°C, displayed the highest shrinkage, with length and width reductions of 133.30 ± 3.85 mm and 25.90 ± 0.87 mm, respectively.

Authors: Ochoa Lina , Skubik-Peplaski Camille
Published: November 2023

Chronic disease prevention, health, and wellness have become primary practice areas for occupational therapy. Occupational therapists (OTs) in pain rehabilitation are established as essential members of comprehensive and multidisciplinary pain management teams, focusing on increasing occupational performance through participation. This study’s purpose was to investigate OTs’ experiences managing chronic pain and to explore OTs’ effectiveness in supporting clients’ wellness and occupational performance through interventions. Eleven OTs ( n = 11) participated with three themes emerging on chronic pain, interventions, and holistic teams. Findings suggest that OTs are successful at treating chronic pain, supporting wellness and occupational performance when their interventions are health-promoting, and clients are enabled to take an active role in their chronic pain management. This study demonstrates the critical impact OTs can have in multidisciplinary teams on clients’ outcomes, such as increased occupational performance, wellness, and quality of life (QOL) through engagement in meaningful occupations.

Authors: Pituch Evelina , Cormier Tiffanie , Gilbert Véronique , Bottari Carolina
Published: November 2023

The assistance needs of parents with physical disabilities have been widely underexamined. This qualitative observational study described the assistance needs of parents with physical disabilities during the performance of in-home babycare activities. Thirty-one parents were assessed by trained occupational therapists using the Activities of Daily Living (ADL) Profile adapted for use with parents, an ecological performance-based assessment that considers executive functioning. Descriptive statistics of participants’ demographics and parents’ independence scores in babycare activities were calculated, and a qualitative content analysis of parents’ assistance needs was performed using video recordings. At least one-fourth of parents experienced difficulties in all babycare activities, either affecting activity performance or requiring verbal or physical assistance. Assistance needs were also observed in all activity-related operations of the ADL Profile. It is necessary to develop specialized clinical services to address assistance needs and promote safe and easy parenting in parents with physical disabilities.
Obstructive Sleep Apnea: Strategies for Screening, Management, and Overcoming Treatment Challenges in the Outpatient Setting

Published: November 2023

Obstructive sleep apnea (OSA) is characterized by repetitive airway closure, which can lead to hypoxemia and sympathetic nervous system activation. This can result in significant cardiovascular and neurologic morbidity. Therefore, early recognition and treatment are extremely important. The gold standard treatment of OSA is positive airway pressure, which has been shown to decrease the risk of these sequelae. Alternatives to positive airway pressure therapy are not commonly discussed but are available to those who are not able to tolerate positive airway pressure. The goal of this review is to discuss the pathophysiology, epidemiology, screening and testing, and treatment considerations for OSA.

Authors: Abbas Munawar , Khan Nargis
Published: November 2023

The current study investigates incompressible, MHD flow of Cross nanofluid containing of gyrotactic microorganisms and thermophoretic particle deposition over a sheet with activation energy and variable thermal conductivity. The variable characteristic of thermal conductivity is considered as a linear function of temperature. The present study’s insights can optimize the design of nanofluid-based systems, enhance drug delivery methods, improve environmental monitoring, refine materials engineering, advance microfluidics for diagnostics, boost renewable energy technologies, and upgrade electronics cooling solutions. Moreover, this study contribution to scientific understanding will catalyze further research across disciplines, fostering innovation and progress. Cross nanofluid containing iron oxide [Formula: see text] nanoparticles, and based fluid ethylene glycol ([Formula: see text] is used. In the current study, distributions of concentration, temperature, mass, microorganisms, and flow are examined in the presence of nanofluid while also accounting for thermophoretic particle deposition and a heat source. The proposed flow equations are transmuted into ODEs by employing the suitable similarity variables. RKF-45th approach is used to evaluate the reduced equations. Graphs are used to determine the effects of important factors on thermal, microorganism, concentration, and flow profiles. With a rise in the Marangoni ratio parameter, the velocity distribution is enhanced, whereas the temperature distribution exhibit inverse behavior.
Access to and quality of care for sexual and gender minority women living with HIV in Metro Vancouver, Canada: Results from a longitudinal cohort study
Authors: Perrin H , Shannon K , Lowik AJ , Rich A , Baral S , Braschel M , Deering K
Published: November 2023

Background:

While scarce, literature suggests that women at the intersection of HIV status and gender and/or sexual minority identities experience heightened social and health disparities within health care systems.

Objectives:

This study examines the association between sexual and/or gender minority identities and: (1) experiences of poor treatment by health professionals and (2) being unable to access health services among a cohort of women living with HIV in Metro Vancouver, Canada.

Design:

Data were drawn from a longitudinal community–based cohort of women living with HIV (Sexual Health and HIV/AIDS Women’s Longitudinal Needs Assessment).

Methods:

We examined associations between sexual and/or gender minority identities and the two outcomes. We drew on explanatory variables to measure sexual minority and gender minority identities independently and a combined variable measuring sexual and/or gender minority identities. The associations between each of these three variables and each outcome were analysed using bivariate and multivariable logistic regression models with generalized estimating equations for repeated measures over time. Adjusted odds ratios and 95% confidence intervals are reported.

Results:

The study sample included 1460 observations on 315 participants over 4.5 years (September 2014 to February 2019). Overall, 125 (39.7%) reported poor treatment by health professionals and 102 (32.4%) reported being unable to access health care services when needed at least once over the study period. A total of 110 (34.9%) of participants reported sexual and/or gender minority identities, 106 (33.7%) reporting sexual minority identities, with 29 (9.2%) reporting gender minority identities. In multivariable analysis, adjusting for confounders, sexual minority identities, and combined sexual and/or gender minority identities were significantly associated with increased odds of experiencing poor treatment by health professionals (sexual minority adjusted odds ratio = 1.39 (0.94–2.05); sexual and/or gender minority adjusted odds ratio = 1.48 (1.00–2.18)) and being unable to access health services (sexual minority adjusted odds ratio = 1.89 (1.20–2.97); sexual and/or gender minority adjusted odds ratio = 1.91 (1.23–2.98)). In multivariable analysis, gender minority identities were not significantly associated with increased odds of experiencing poor treatment by health professionals (gender minority adjusted odds ratio = 1.38; 95% CI = 0.76–2.52) and being unable to access health services (gender minority adjusted odds ratio = 1.72; 95% CI = 0.89–3.31) possibly due to low sample size among women with gender minority identities.

Conclusion:

Our findings suggest the need for access to inclusive, affirming, trauma-informed health care services tailored specifically for and by women living with HIV with sexual and/or gender minority identities.

Authors: Almeida-Neto Paulo Francisco de , de Medeiros Jason Azevedo , Jaggers Jason R. , Ferreira Ayrton Bruno de Morais , de Assis Gilmara Gomes , Cabral Breno Guilherme de Araújo Tinôco , Dantas Paulo Moreira Silva
Published: November 2023

Context:

Exercise immunology is aimed at understanding how exercise sessions can affect the immune system in athletic subjects of different age groups. The objective of the current study was to discuss in which stage of biological maturation (BM) young athletes may be more vulnerable in relation to the immune system, and whether there is a BM range in which it is safer to perform sports training with strenuous exercise loads.

Evidence Acquisition:

Evidence from scientific research from several scientific disciplines (eg, immunology, sport immunology, pediatrics, sports medicine, human development) was gathered to holistically examine the main particularities of exercise immunology as applied to pediatric sport.

Study Design:

Narrative review.

Level of Evidence:

Level 5.

Results:

In pediatric patients, lymphoid tissue expands during puberty and involutes after puberty until it returns to pre-expansion values. This suggests that there is a specific period in which the immune system may be stronger, which may provide opportunities for strenuous exercise in pediatric athletes. However, the chronological period when puberty occurs will be determined by BM, which is the rate at which the biological systems of the human body improves. This may affect the period of lymphoid tissue expansion and, consequently, the behavior of the immune system in pediatric subjects of the same age category.

Conclusion:

During puberty, there is a significant increase in the proinflammatory profile; to compensate for this, there is an expansion of lymphoid tissue that may favor the efficiency of the immune system. The period in which puberty is reached may vary according to the stages of BM. Therefore, in exercise immunology applied to pediatric sports, in addition to external and internal training loads, it is necessary to consider BM and puberty, which have been shown to be safer biomarkers than chronological age for determining immune system behavior in pediatric athletes.

Clinical impact of pharmacists’ interventions in intensive care units in a tertiary institution in Singapore – A retrospective cohort study
Authors: Soong Jie Lin , Ang Lee Yi , Chan Jeremy Lin En , Lie Sui An
Published: November 2023

Background and aim

Previous studies have deemed pharmacists essential in the intensive care units (ICU) to provide quality healthcare and ensure medication safety. As the impact of pharmacists in ICU varies according to different factors, our study aims to characterise and evaluate the impact of pharmacists’ interventions in ICUs in Singapore, to enable the identification of areas of improvement in our critical care pharmacy practice.

Methods

We retrospectively evaluated 7 months of pharmacists’ interventions in five ICUs at Singapore General Hospital. Interventions were classified based on the medication-related problems (MRPs) addressed. The impact of pharmacists’ interventions was assessed by rating the severity of error in medication order, the clinical relevance of intervention, and the probability of adverse drug events (pADE) that would have occurred without pharmacists’ interventions.

Results

There were 619 interventions addressing 775 MRPs, of which 91.1% were accepted. The main MRP identified was inappropriate drug regimen (49.2%) and the medication class most frequently involved in MRPs was anti-infectives (56.9%). Majority of the interventions were rated as significant for both the severity of error (76.9%) and clinical relevance (72.4%). However, the pADE was deemed to be low (61.2%). The rating of pADE may be affected by the lack of information in patient profiles.

Conclusion

COVID-19, pneumonia, and tuberculosis have had a significant effect on recent global health. Since 2019, COVID-19 has been a major factor underlying the increase in respiratory-related terminal illness. Early-stage interpretation and identification of these diseases from X-ray images is essential to aid medical specialists in diagnosis. In this study, (COV-X-net19) a convolutional neural network model is developed and customized with a soft attention mechanism to classify lung diseases into four classes: normal, COVID-19, pneumonia, and tuberculosis using chest X-ray images. Image preprocessing is carried out by adjusting optimal parameters to preprocess the images before undertaking training of the classification models. Moreover, the proposed model is optimized by experimenting with different architectural structures and hyperparameters to further boost performance. The performance of the proposed model is compared with eight state-of-the-art transfer learning models for a comparative evaluation. Results suggest that the COV-X-net19 outperforms other models with a testing accuracy of 95.19%, precision of 96.49% and F1-score of 95.13%. Another novel approach of this study is to find out the probable reason behind image misclassification by analyzing the handcrafted imaging features with statistical evaluation. A statistical analysis known as analysis of variance test is performed, to identify at which point the model can identify a class accurately, and at which point the model cannot identify the class. The potential features responsible for the misclassification are also found. Moreover, Random Forest Feature importance technique and Minimum Redundancy Maximum Relevance technique are also explored. The methods and findings of this study can benefit in the clinical perspective in early detection and enable a better understanding of the cause of misclassification.

Background

Online advertisements on social media platforms are an important tool for engaging relevant populations in public health research. However, little is known about what platforms and ad characteristics are most effective in engaging high-priority HIV populations, including racial/ethnic and sexual minority individuals.

Methods

Data from this study were drawn from advertising campaigns conducted on popular websites and social media platforms that recruited for several nationwide randomized controlled trials of various HIV prevention and testing strategies among sexual minority men (SMM) from December 2019 until March 2022. Descriptive statistics and LASSO regression models were used to determine which platforms and ad characteristics were associated with significantly higher odds of engagement.

Results

Ads on Google search, Facebook, and Instagram yielded the most cost-effective engagement, while gay-oriented dating platforms and TrafficJunky yielded the highest percentage of users who appeared to meet basic eligibility criteria. The highest percentages of Black users were screened through ads on Jack’d, TrafficJunky, and Google search; for Hispanic/Latino users, Google search, Grindr, Facebook, and Instagram. Analyzing ad characteristics, we found ads that used suggestive content, animation, and included study or institution logos were associated with greater engagement. Ads that emphasized convenience of the research (e.g. mentioned participating “from home”) and that depicted people of similar races/ethnicities were also associated with greater engagement among Black and Hispanic/Latino sexual minority men.

Conclusions

We found that advertisements on mainstream social media sites are most cost effective. Although gay-oriented dating platforms were much more effective at reaching the target population, they were considerably more expensive. We also identified ad characteristics that were particularly effective in engaging users. These results could inform the design of online public health outreach campaigns for similar populations to improve their engagement and reach. Findings also demonstrated the value of conducting focused research on the effectiveness of various online marketing strategies.
Balancing the Scales of Explainable and Transparent AI Agents within Human-Agent Teams

With the progressive nature of Human-Agent Teams becoming more and more useful for high-quality work output, there is a proportional need for bi-directional communication between teammates to increase efficient collaboration. This need is centered around the well-known issue of innate mistrust between humans and artificial intelligence, resulting in sub-optimal work. To combat this, computer scientists and humancomputer interaction researchers alike have presented and refined specific solutions to this issue through different methods of AI interpretability. These different methods include explicit AI explanations as well as implicit manipulations of the AI interface, otherwise known as AI transparency. Individually these solutions hold considerable merit in repairing the relationship of trust between teammates, but also have individual flaws. We posit that the combination of different interpretable mechanisms mitigates each other’s flaws and extenuates their strengths within human-agent teams.
Teaching Audience Adaptation With Value Frameworks
Authors: Reinsch Nelson Lamar
Published: November 2023

Communication instructors have long insisted on the importance of audience adaptation. But they have said less about (a) the dimensions along which adaptation might proceed or (b) how a student might learn the art of adapting. In this article, I contribute toward addressing these two deficiencies. I suggest a dimension for adaptation—the value frameworks (or value vocabularies) in which people express evaluations of better and worse. And I propose that instructors teach adaptation by imitation. In addition to elaborating on these ideas, I also offer materials for use in classes.
Trading on Diverse Relationships: The Process of Racialized Social Commodification in Multiracial Congregations

Diverse organizations focus on appearing progressive but, in practice, may reproduce internal and external racial inequalities. Previous research has focused on how organizations with superficial levels of diversity may be detrimental to racial equity; are organizations with deep and sustained, cross-racial relationships any better? Drawing on in-depth interviews, field notes, and surveys of 121 head clergy of multiracial churches, we examine the strategies of leaders of multiracial churches to raise funds for their organizations. Our systematic analysis reveals how these, mostly White, religious leaders act as brokers by leveraging embeddedness with congregants of color, social and cultural capital within institutions valuing diversity, and the racial status of their organizations to gain access to social and organizational benefits. We develop a theoretical concept called “racialized social commodification” (RSC) to explore how leaders convert the racial capital of people of color into social and economic resources in contexts of substantive diversity. Through RSC, even organizations boasting strong, cross-racial relationships continue to reproduce racial inequality by protecting power and resource hierarchies that benefit White Americans.
