Beyond the incident: Influences on the perception of multiple instances of discrimination

Br J Soc Psychol. 2024 May 25. doi: 10.1111/bjso.12762. Online ahead of print.

ABSTRACT

This article seeks to enhance the theoretical understanding of discrimination perception, especially in contexts with relevant statistical information. Previous research has provided important insights into the perception of single, ambiguous instances of discrimination. However, the generalizability of these insights to scenarios involving multiple, repeated instances of discrimination remains unclear. The current research aims to reduce this uncertainty by investigating whether three key determinants of discrimination perception in single instances – perpetrators’ prototypicality, victims’ control, and system-justifying beliefs (SJB) – also influence observers’ perceptions of repeated discrimination. In Experiments 1 and 2, participants perceived stronger discrimination when perpetrators were prejudiced members of the advantaged group. In Experiments 3 and 4, perceived discrimination intensified when victims had low control, a trend significantly noted in tabular presentations but not in sequential ones. In Experiments 5 and 6, a negative correlation between SJB and discrimination perception was observed. The theoretical and practical implications of these results, as well as open questions, are discussed. Overall, these studies advance our knowledge of discrimination perception in multiple instances. They highlight the intricate interplay between statistical data, moral judgements, and individual belief systems, paving the way for a more nuanced exploration of the underlying psychological processes of discrimination perception.

The impact of treatment for childhood classical Hodgkin lymphoma according to the EuroNet-PHL-C2 protocol on serum anti-Müllerian Hormone

Hum Reprod. 2024 May 24:deae112. doi: 10.1093/humrep/deae112. Online ahead of print.

ABSTRACT

STUDY QUESTION: What is the impact of the EuroNet-PHL-C2 treatment protocol for children with classical Hodgkin lymphoma (cHL) on gonadal function in girls, based on assessment of serum anti-Müllerian hormone (AMH)?

SUMMARY ANSWER: Serum AMH levels decreased after induction chemotherapy and increased during subsequent treatment and 2 years of follow-up, with lowest levels in patients treated for advanced stage cHL.

WHAT IS KNOWN ALREADY: Treatment for cHL, particularly alkylating agents and pelvic irradiation, can be gonadotoxic and result in premature reduction of primordial follicles in females. The current EuroNet-PHL-C2 trial aims to reduce the use of radiotherapy in standard childhood cHL treatment, by intensifying chemotherapy. This study aims to assess the gonadotoxic effect of the EuroNet-PHL-C2 protocol.

STUDY DESIGN, SIZE, DURATION: This international, prospective, multicenter cohort study is embedded in the EuroNet-PHL-C2 trial, an European phase-3 treatment study evaluating the efficacy of standard cHL treatment with OEPA-COPDAC-28 (OEPA: vincristine, etoposide, prednisone, and doxorubicin; COPDAC-28: cyclophosphamide, vincristine, prednisone, and dacarbazine) versus intensified OEPA-DECOPDAC-21 (DECOPDAC-21: COPDAC with additional doxorubicin and etoposide and 25% more cyclophosphamide) in a randomized setting. Participants were recruited between January 2017 and September 2021.

PARTICIPANTS/MATERIALS, SETTING, METHODS: Female patients aged ≤18 years, treated according to the EuroNet-PHL-C2 protocol for cHL were recruited across 18 sites in the Netherlands, Belgium, Germany, Austria, and Czech Republic. All parents and patients (aged ≥12 years old) provided written informed consent. Serum AMH levels and menstrual cycle characteristics were evaluated over time (at diagnosis, one to three times during treatment and 2 up to 5 years post-diagnosis) and compared between treatment-levels (TL1, TL2, and TL3) and treatment-arms (OEPA-COPDAC-28 and OEPA-DECOPDAC-21). Serum samples obtained from patients after receiving pelvic radiotherapy were excluded from the main analyses.

MAIN RESULTS AND THE ROLE OF CHANCE: A total of 104 females, with median age at diagnosis of 15.6 years (IQR 13.7; 17.0), were included in the analysis. Ninety-nine were (post)pubertal. Eighteen girls were diagnosed with an early stage of cHL (TL1) and 86 with intermediate or advanced stage disease (50 TL2 and 36 TL3, 66% received COPDAC-28 and 34% DECOPDAC-21). Five patients received pelvic radiotherapy. Median AMH level at diagnosis was 1.7 µg/l (IQR 0.9; 2.7). After two courses of OEPA chemotherapy, AMH levels decreased substantially in all patients (98% <0.5 µg/l), followed by a significant increase during the consolidation treatment and follow-up. After 2 years, 68% of patients reached their baseline AMH value, with overall median recovery of 129% (IQR 75.0; 208.9) compared to baseline measurement. Five patients (7%) had AMH <0.5 µg/l. In patients treated for advanced stage disease, AMH levels remained significantly lower compared to early- or intermediate stage disease, with median serum AMH of 1.3 µg/l (IQR 0.8; 2.1) after 2 years. Patients who received DECOPDAC-21 consolidation had lower AMH levels during treatment than patients receiving COPDAC-28, but the difference was no longer statistically significant at 2 years post-diagnosis. Of the 35 postmenarchal girls who did not receive hormonal co-treatment, 19 (54%) experienced treatment-induced amenorrhea, two girls had persisting amenorrhea after 2 years.

LIMITATIONS, REASONS FOR CAUTION: The studied population comprises young girls with diagnosis of cHL often concurring with pubertal transition, during which AMH levels naturally rise. There was no control population, while the interpretation of AMH as a biomarker during childhood is complex. The state of cHL disease may affect AMH levels at diagnosis, potentially complicating assessment of AMH recovery as a comparison with baseline AMH. The current analysis included data up to 2-5 years post-diagnosis.

WIDER IMPLICATIONS OF THE FINDINGS: The current PANCARE guideline advises to use the cyclophosphamide-equivalent dose score (CED-score, as an estimation of cumulative alkylating agent exposure) with a cut-off of 6000 mg/m2 to identify females aged <25 years at high risk of infertility. All treatment-arms of the EuroNet-PHL-C2 protocol remain below this cut-off, and based on this guideline, girls treated for cHL should therefore be considered low-risk of infertility. However, although we observed an increase in AMH after chemotherapy, it should be noted that not all girls recovered to pre-treatment AMH levels, particularly those treated for advanced stages of cHL. It remains unclear how our measurements relate to age-specific expected AMH levels and patterns. Additional (long-term) data are needed to explore clinical reproductive outcomes of survivors treated according to the EuroNet-PHL-C2 protocol.

STUDY FUNDING/COMPETING INTEREST(S): The fertility add-on study was funded by the Dutch charity foundation KiKa (project 257) that funds research on all forms of childhood cancer. C.M-K., D.K., W.H.W., D.H., M.C., A.U., and A.B. were involved in the development of the EuroNet-PHL-C2 regimen. The other authors indicated no potential conflicts of interest.

Quantitative MRI Analysis of Patellofemoral Joint Cartilage Health 2-Years Postoperative Anterior Cruciate Ligament Reconstruction and Lateral Extra-Articular Tenodesis

Am J Sports Med. 2024 May 25:3635465241248642. doi: 10.1177/03635465241248642. Online ahead of print.

ABSTRACT

BACKGROUND: The addition of an iliotibial band-based lateral extra-articular tenodesis (LET) to anterior cruciate ligament (ACL) reconstruction (ACLR) has been shown to reduce failure rates. However, there are concerns as to the potential overconstraint of tibiofemoral kinematics that may increase the risk of cartilage degradation. To date, no clinical study has investigated the effect of LET on patellofemoral joint articular cartilage health.

HYPOTHESIS: It was hypothesized that at 2 years postoperatively, (1) the addition of LET at the time of ACLR would have no effect on cartilage health on magnetic resonance imaging (MRI), and (2) higher cartilage relaxation values would be associated with worse patient-reported and functional outcomes.

STUDY DESIGN: Cohort study; Level of evidence, 3.

METHODS: A subset of patients from the STABILITY 1 randomized controlled trial were included. All patients underwent primary ACLR with a hamstring autograft. Patients were randomized to either LET augmentation or not. Cartilage status in the patellofemoral joint between the ACLR group and ACLR+LET group was compared using 2-year postoperative quantitative MRI and the ACL osteoarthritis scores of both the surgical and the contralateral nonsurgical knees. Objective functional outcomes and patient-reported outcome measures (PROMs) were attained.

RESULTS: A total of 92 patients (43 patients in the ACLR group; mean age, 18.9 ± 3.2 years; 60.5% female; and 49 patients in the ACLR+LET group; mean age, 18.7 ± 3.2 years, 63.3% female) were included. No significant differences were seen in the mean values (ms) for adjusted T1ρ/T2 relaxation times in the medial patella (47.8/42.2 vs 47.3/43.2), central patella (45.5/42.5 vs 44.1/42.7), lateral patella (48.2/43.5 vs 47.3/43.0), medial trochlea (54.7/50.9 vs 56.4/50.9), central trochlea (53.3/51.1 vs 53.1/52.0), and lateral trochlea (54.9/52.1 vs 53.9/52.6) between the ACLR and ACLR+LET groups. No difference in overall ACL osteoarthritis scores was observed (P = .99). An increase in medial patellar T2 relaxation times was associated with a decreasing International Knee Documentation Committee score (P = .046), Knee injury and Osteoarthritis Outcome Score (KOOS) Symptoms subscale score (P = .01), and total KOOS (P = .01).

CONCLUSION: There was no statistical difference in patellofemoral cartilage health between knees 2 years after primary ACLR with hamstring tendon autograft with or without LET. Statistically significant correlations were found between quantitative MRI relaxation times, functional outcome scores, and PROMs; however, the correlations were weak and the clinical significance is unknown.

Theoretical analysis of J-transform decomposition method with applications of nonlinear ordinary differentialequations

Sci Prog. 2024 Apr-Jun;107(2):368504241256864. doi: 10.1177/00368504241256864.

ABSTRACT

One of the most noteworthy differential equations of the first order is the Riccati differential equation. It is applied in various branches of mathematics, including algebraic geometry, physics, and conformal mapping theory. The J-transform Adomian decomposition method is employed in the current study to find exact solutions for different kinds of nonlinear differential equations. We give thorough detailed proofs for new theorems related to the J-transform technique. The Adomian decomposition method and the J-transform method serve as the foundation for this technique. For certain differential equations, the theoretical analysis of the J-transform Adomian decomposition method is examined and is computed using readily computed terms. Our findings are contrasted with exact solutions found in the literature that were produced using alternative techniques. The significant features of the J-transform Adomian decomposition method are described in the article. It has been shown that the J-transform Adomian decomposition method is very efficient, useful, and adaptable to a broad variety of linear and nonlinear differential equations. Most of the symbolic and numerical calculations were performed using Mathematica.

Accuracy of Provider Predictions of Viral Suppression Among Adolescents and Young Adults With HIV in an HIV Clinical Program

J Int Assoc Provid AIDS Care. 2024 Jan-Dec;23:23259582241252587. doi: 10.1177/23259582241252587.

ABSTRACT

BACKGROUND: Providers caring for adolescents and young adults with HIV (AYA-HIV) mostly base their adherence counseling during clinical encounters on clinical judgment and expectations of patients’ medication adherence. There is currently no data on provider predictions of viral suppression for AYA-HIV. We aimed to assess the accuracy of provider predictions of patients’ viral suppression status compared to viral load results.

METHODS: Providers caring for AYA-HIV were asked to predict the likelihood of viral suppression of patients before a clinical encounter and give reasons for their predictions. Provider predictions were compared to actual viral load measurements of patients. Patient data were abstracted from electronic health records. The final analysis included 9 providers, 28 patients, and 34 observations of paired provider predictions and viral load results.

RESULTS: Provider prediction accuracy of viral suppression was low (59%, Cohen’s Kappa = 0.16). Provider predictions of lack of viral suppression were based on nonadherence to medications, new patient status, or structural vulnerabilities (e.g., unstable housing). Anticipated viral suppression was based on medication adherence, history of viral suppression, and the presence of family or other social forms of support.

CONCLUSIONS: Providers have difficulty accurately predicting viral suppression among AYA-HIV and may base their counseling on incorrect assumptions. Rapid point-of-care viral load testing may provide opportunities to improve counseling provided during the clinical encounter.

Tuberculosis impacts multiple aspects in quality of life in a Romanian cohort of drug-susceptible and drug resistant patients: A patient-reported outcome measures study

Trop Med Int Health. 2024 May 24. doi: 10.1111/tmi.13996. Online ahead of print.

ABSTRACT

BACKGROUND: Tuberculosis (TB), and especially its drug resistant forms, is responsible for not only significant mortality, but also considerable morbidity, still under-quantified. This study used four Patient-Reported Outcome Measures (PROMS) to assess the status of persons affected by drug-susceptible and drug-resistant TB during their TB treatment or after treatment completion, in Romania, the highest TB burden country in the EU.

METHODS: People affected by TB in two different regions in Romania were included during and after treatment, following a cross-sectional design. PROMs used were SF-36, EQ-5D-5L, WPAI and the app-based audiometry screening tool ‘uHear.’ Descriptive statistics and relevant statistical tests were used to compare groups between themselves and with the general Romanian population.

RESULTS: Both patients with drug-susceptible and drug-resistant TB experience, with drug-resistant patients experiencing statistically significantly more pain and hearing loss. PROMs show some improvement in the after-treatment group; however, compared with the general Romanian population for which data were available, all groups scored lower on all outcome measures.

CONCLUSION: PROMs offer the possibility of obtaining a more comprehensive view of patients’ status, by involving them directly in the medical process and could guide a rehabilitation strategy.

Sarcopenia is a possible risk factor for amputation after peripheral arterial interventions

Vascular. 2024 May 24:17085381241255259. doi: 10.1177/17085381241255259. Online ahead of print.

ABSTRACT

OBJECTIVES: Sarcopenia has been demonstrated to be related to unfavorable clinical outcomes in patients with vascular diseases. The purpose of this study is to evaluate the relationship between sarcopenia and clinical results in patients with peripheral arterial disease who underwent endovascular therapy (EVT).

METHODS: This single-center retrospective study involved patients with PAD who underwent peripheral EVT at Ankara City Hospital, between January 2018 and December 2021. Two groups of patients were created: sarcopenic and non-sarcopenic patients according to computed tomography angiography muscle measurements. Primary outcome measures were major and minor amputation and survival. Mortality, amputation, and clinical characteristics were compared between the two patient groups. Hazard ratios (HRs) for amputation were calculated for each risk factor via univariate and multivariate analyses. Secondary outcomes included length of hospital stay and post-procedural complications.

RESULTS: The mean follow-up period was 29.9 ± 9 months for all patients. A total number of 100 patients (mean age 63.5 ± 9.2 years) were involved in the study cohort. A significant association was identified between mortality and sarcopenia (p < .001). The mortality rate in the group with sarcopenia was significantly higher than the other group; 65.7% (23 patients) versus (20%, 13 patients) (p < .001). The major amputation rate in the group with sarcopenia was 57.1%, the major amputation rate in the group without sarcopenia was calculated as 15.4%, revealing that the major amputation rate was detected to be significantly higher in the sarcopenia group (p < .001). Multivariate regression analyses showed that only sarcopenia (HR, 0.52; 95% CI, 0.21-1.27; p = 0.15) was independently associated with major amputation in patients with PAD after EVT. Kaplan-Meier analysis revealed a statistically significant difference between the survival curves of sarcopenia and non-sarcopenia patients (p < .001).

CONCLUSIONS: Sarcopenia seems to be a possible risk factor associated with amputation in patients with PAD who undergo EVT. The results of this study imply that sarcopenia is a possible risk factor for overall survival in patients with PAD.

Assessing Lifestyle Patterns and Their Influence on Weight Status in Students from a High School in Sibiu, Romania: An Adaptation of ISCOLE Questionnaires and the Child Feeding Questionnaire

Nutrients. 2024 May 20;16(10):1532. doi: 10.3390/nu16101532.

ABSTRACT

The escalation of global obesity is driving research to understand environmental influences on this process, particularly during vulnerable developmental stages such as childhood and adolescence. Efforts include the development of various structured data collection tools. We aimed to adapt a series of previously validated questionnaires from the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE), the Child Feeding Questionnaire, and elements from the World Health Organization Childhood Obesity Surveillance Initiative (COSI) in order to assess local lifestyle patterns among Romanian high school students and their families that may predispose them to obesity. To this goal, an expert committee was formed as part of a research partnership to oversee the questionnaire’s translation and adaptation. It consisted of education and school management specialists, clinical research professionals, language experts, and public health experts. The adapted questionnaires were then applied to 114 students enrolled in the 9th and 10th grades attending a high school situated in Sibiu, and their parents. The variables measured were investigated for correlations with overweight and obesity and, as a secondary objective, academic performance. The study revealed several critical findings, including suboptimal sleep durations and physical activity levels among students, a significant amount of screen time, and correlations between weight status and physical activity, sedentary time, and maternal weight status and education levels. The adapted questionnaires proved to be effective tools in capturing the multifaceted factors implicated in adolescent obesity, providing a foundation for targeted interventions and broader public health strategies to address this issue.

Association between Dietary Patterns during Pregnancy and Children’s Neurodevelopment: A Birth Cohort Study

Nutrients. 2024 May 19;16(10):1530. doi: 10.3390/nu16101530.

ABSTRACT

BACKGROUND: Research studies have showed that maternal diet may influence fetal neurodevelopment, but most studies have only assessed single nutrients or food groups.

OBJECTIVE: To investigate the impact of maternal prenatal dietary patterns during pregnancy on child neurodevelopment.

METHODS: Study participants were obtained from the China National Birth Cohort. The Ages and Stages Questionnaire, Third Edition, was used to assess children’s neurodevelopment at 36 months old. Maternal antenatal dietary data were collected over three trimesters using food frequency questionnaires. Five distinct maternal dietary patterns throughout pregnancy were identified by principal component analysis, namely protein- and micronutrient-rich dietary patterns, low-iron dietary patterns, pasta as the staple food dietary patterns, iron-rich dietary patterns, tubers, fruits, and baked food dietary patterns. Group-based trajectory modeling was performed for dietary patterns present in all three periods. Multiple linear regression models were used for statistical analysis.

RESULTS: Children of mothers who followed a high protein- and micronutrient-rich dietary pattern trajectory during pregnancy presented better neurodevelopment, including higher gross motor and problem-solving scores. Furthermore, it was observed that children born of women with low-iron dietary patterns had poorer neurodevelopment. In detail, children born to mothers with a low-iron dietary pattern during the first trimester had lower problem-solving scores, while to those who were exposed to a low-iron dietary pattern in the second and third trimesters had lower gross motor scores. Additionally, children with mothers who had a low-iron dietary pattern in the third trimester had lower communication scores.

CONCLUSIONS: A nutrition-balanced protein- and micronutrient-rich dietary pattern and adequate iron dietary pattern for mothers throughout pregnancy may be beneficial to children’s neurodevelopment.

The Quality of Menu Offerings in Independently Owned Restaurants in Baltimore, Maryland: Results from Mixed-Methods Formative Research for the FRESH Trial

Nutrients. 2024 May 18;16(10):1524. doi: 10.3390/nu16101524.

ABSTRACT

(1) Background: Independently owned restaurants (IORs) are prevalent in under-resourced racial and ethnic minority communities in the US and present a unique setting for public health nutrition interventions. (2) Methods: We conducted 14 in-depth interviews with IOR owners in Baltimore about their perceptions of healthy food, and customers’ acceptance of healthier menus and cooking methods and concurrent observations of the availability of healthy options on their menus. Qualitative data were coded and analyzed using ATLAS.ti. Observations were analyzed with statistical analysis performed in R. (3) Results: Owners perceived non-fried options, lean proteins, and plant-based meals as healthy. While open to using healthier cooking fats, they had mixed feelings about reducing salt, adopting non-frying methods for cooking, and adding vegetables and whole grains to the menu, and were reluctant to reduce sugar in recipes and beverages. Only 17.5% of 1019 foods and 27.6% of 174 beverages in these IORs were healthy, with no significant differences in the healthfulness of restaurant offerings within low-healthy-food-access/low-income neighborhoods and those outside. (4) Conclusion: Healthy options are generally scarce in Baltimore’s IORs. Insights from owners inform future interventions to tailor healthy menu offerings that are well-received by customers and feasible for implementation.
