ABSTRACT

OBJECTIVE: To describe young adult childhood cancer survivors’ disclosure of their cancer history (i.e., disclosure behavior, difficulty, and timing), perceived partner responses, and associations with relationship status satisfaction.

METHODS: German long-term survivors of childhood cancer (N=509; response rate: 31.3%, age 21-26, 59.7% female) completed a registry-based nationwide survey (embedded mixed methods design, including closed and open-ended questions) on measures about disclosure history (behavior, difficulty, and timing), partner responses, and relationship status satisfaction. Statistical (χ² -, t-, or F-tests) and qualitative analyses were conducted.

RESULTS: Half of all survivors always disclosed their cancer history to romantic partners. Thereby, three themes for considering (non-)disclosure were identified: Survivors’ attitudes, having integrated cancer as part of their identity, and anticipated effects on romantic relationships. About 40% indicated having no difficulties with disclosing their cancer history. The timing of disclosure varied, with most survivors disclosing after a few dates. Facilitators of disclosure were the visibility of their former illness (e.g., scars), having trust in a (potential) partner, getting older/mature, and previous positive experiences with disclosure. Few survivors (13.8%) had ever experienced negative responses from dating partners. Yet, those who had negative experiences, found it more difficult to disclose their cancer history. Survivors were overall rather satisfied with their relationship status, with partnered survivors reporting greater satisfaction than singles (Hedge’s g=1.68); and particularly partnered survivors with past positive responses being most satisfied.

CONCLUSIONS: Young adult childhood cancer survivors appear rather open in disclosing their cancer history to (potential) romantic partners, and few experienced negative responses. Psycho-educational programs may emphasize such findings in helping to prevent fear of disclosure or avoidance of dating and disclosure among survivors. This article is protected by copyright.

ABSTRACT

BACKGROUND: There is a great association between the prevalence of obstructive sleep apnea (OSA) and asthma. Nonetheless, whether OSA impacts lung function, symptoms, and control in asthma and whether asthma increases the respiratory events in OSA are unknown. This meta-analysis aimed to examine the relationship between obstructive sleep apnea and asthma severity and vice versa.

METHODS: We carried out a systematic search of PubMed, EMBASE, and Scopus from inception to September 2022. Primary outcomes were lung function, parameters of polysomnography, the risk of OSA in more severe or difficult-to-control asthmatic patients, and the risk of asthma in patients with more severe OSA. Heterogeneity was examined with the Q test and I² statistics. We also performed subgroup analysis, Meta-regression, and Egger’s test for bias analysis.

RESULTS: 34 studies with 27,912 subjects were totally included. The results showed that the comorbidity of OSA aggravated lung function in asthmatic patients with a consequent decreased forced expiratory volume in one second %predicted (%FEV1) and the effect was particularly evident in children. %FEV1 tended to decrease in adult asthma patients complicated with OSA, but did not reach statistical significance. Interestingly, the risk of asthma seemed to be slightly lower in patients with more severe OSA (OR = 0.87, 95%CI 0.763-0.998). Asthma had no significant effect on polysomnography, but increased daytime sleepiness assessed by the Epworth Sleepiness Scale in OSA patients (WMD = 0.60, 95%CI 0.16-1.04). More severe asthma or difficult-to-control asthma was independently associated with OSA (odds ratio (OR) = 4.36, 95%CI 2.49-7.64).

CONCLUSION: OSA was associated with more severe or difficult-to-control asthma with decreased %FEV₁ in children. The effect of OSA on lung function in adult patients should be further confirmed. Asthma increased daytime sleepiness in OSA patients. More studies are warranted to investigate the effect of asthma on OSA severity and the impact of different OSA severity on the prevalence of asthma. It is strongly recommended that people with moderate-to-severe or difficult-to-control asthma screen for OSA and get the appropriate treatment.

ABSTRACT

BACKGROUND: The majority of the African population lives in rural areas where they heavily depend on crop and livestock production for their livelihoods. Given their socio-economic importance, we initiated a standardized multi-country (Benin, Burkina Faso, Ghana, Nigeria, Ethiopia Tanzania and Uganda) surveillance study to assess the current status of important tick-borne haemoparasites (TBHPs) of cattle.

METHODS: We assessed pathogen prevalences (Anaplasma marginale, Anaplasma centrale, Babesia bigemina, Babesia bovis, Ehrlichia ruminantium, and Theileria parva) in the blood of 6447 animals spread over fourteen districts (two districts per country). In addition, we screened for intrinsic (sex, weight, body condition) and extrinsic (husbandry, tick exposure) risk factors as predictors of infections with TBHPs.

RESULTS: There was a large macro-geographic variation observed in A. marginale, B. bigemina, B. bovis and E. ruminantium prevalences. Most correlated with the co-occurrence of their specific sets of vector-competent ticks. Highest numbers of infected cattle were found in Ghana and Benin, and lowest in Burkina Faso. While T. parva was seldomly found (Uganda only: 3.0%), A. marginale was found in each country with a prevalence of at least 40%. Babesia bovis infected individuals had lower body condition scores. Age (as estimated via body weight) was higher in A. marginale infected cattle, but was negatively correlated with B. bigemina and E. ruminantium prevalences. Ehrlichia ruminantium infection was more often found in males, and A. marginale more often in transhumance farming. High levels of co-infection, especially the combination A. marginale × B. bigemina, were observed in all countries, except for Uganda and Burkina Faso. Babesia bigemina was more or less often observed than expected by chance, when cattle were also co-infected with E. ruminantium or A. marginale, respectively.

CONCLUSIONS: Tick-borne pathogens of cattle are ubiquitous in African’s smallholder cattle production systems. Our standardized study will help a wide range of stakeholders to provide recommendations for TBHP surveillance and prevention in cattle, especially for B. bovis which heavily impacts production and continues its spread over the African continent via the invasive Rhipicephalus microplus tick.

ABSTRACT

BACKGROUND: This study aimed to develop cardiovascular disease (CVD) risk equations for Chinese patients with newly diagnosed type 2 diabetes (T2D) to predict 10-, 20-, and 30-year of risk.

METHODS: Risk equations for forecasting the occurrence of CVD were developed using data from 601 patients with newly diagnosed T2D from the Da Qing IGT and Diabetes Study with a 30-year follow-up. The data were randomly assigned to a training and test data set. In the training data set, Cox proportional hazard regression was used to develop risk equations to predict CVD. Calibration was assessed by the slope and intercept of the line between predicted and observed probabilities of outcomes by quintile of risk, and discrimination was examined using Harrell’s C statistic in the test data set. Using the Sankey flow diagram to describe the change of CVD risk over time.

RESULTS: Over the 30-year follow-up, corresponding to a 10,395 person-year follow-up time, 355 of 601 (59%) patients developed incident CVD; the incidence of CVD in the participants was 34.2 per 1,000 person-years. Age, sex, smoking status, 2-h plasma glucose level of oral glucose tolerance test, and systolic blood pressure were independent predictors. The C statistics of discrimination for the risk equations were 0.748 (95%CI, 0.710-0.782), 0.696 (95%CI, 0.655-0.704), and 0.687 (95%CI, 0.651-0.694) for 10-, 20-, and 30- year CVDs, respectively. The calibration statistics for the CVD risk equations of slope were 0.88 (P = 0.002), 0.89 (P = 0.027), and 0.94 (P = 0.039) for 10-, 20-, and 30-year CVDs, respectively.

CONCLUSIONS: The risk equations forecast the long-term risk of CVD in patients with newly diagnosed T2D using variables readily available in routine clinical practice. By identifying patients at high risk for long-term CVD, clinicians were able to take the required primary prevention measures.

ABSTRACT

BACKGROUND: Menstruation is a normal biological process that all women go through, yet it is shrouded in secrecy, taboos, and even stigma in many societies. Studies have shown that women from socially disadvantaged groups are more likely to have preventable reproductive health issues and have less understanding of hygienic menstrual practices. Therefore, this study aimed to provide an insight into the most sensitive issue of menstruation and menstrual hygiene practices among the women of the Juang tribe, recognized as one of the particularly vulnerable tribal groups (PVTG) in India.

METHODS: A cross-sectional study using a mixed-method approach was carried out among Juang women in Keonjhar district of Odisha, India. Quantitative data was gathered from 360 currently married women to assess practices associated with menstruation and its management. In addition, 15 focus group discussions and 15 in-depth interviews were conducted to explore the views of Juang women on menstrual hygiene practices, cultural beliefs, menstrual problems, and treatment-seeking behaviour. Inductive content analysis was used to analyse the qualitative data, while descriptive statistics and chi-squared tests were used to analyse quantitative data.

RESULTS: Most Juang women (85%) used old clothes as absorbents during menstruation. Distance from the market (36%), lack of awareness (31%), and high cost (15%) were cited as the contributing factors to the low level of sanitary napkin usage. Around 85% of women were restricted from participating in religious activities, and 94% avoided social gatherings. Seventy-one percent of the Juang women experienced menstrual problems, while only one-third of them sought treatment for their problems.

CONCLUSION: Hygienic practices during menstruation are far from satisfactory among Juang women in Odisha, India. Menstrual problems are common, and the treatment sought is insufficient. There is a need for awareness generation on menstrual hygiene, the adverse effects of menstrual problems, and the provision of low-cost sanitary napkins among this disadvantaged, vulnerable tribal group.

ABSTRACT

BACKGROUND: Developing reflective capacity and critical thinking is one of the prerequisites of education in health professions, especially medicine. This study aimed to determine the reflective capacity of medical students and its role in their critical thinking disposition.

METHODS: In this cross-sectional descriptive research, conducted in 2022, a total of 240 medical intern students were selected using the convenient sampling method. Data were collected using a reflective capacity questionnaire and critical thinking disposition questionnaire and analyzed with descriptive and inferential statistics using SPSS20.

RESULTS: The mean reflective capacity was 4.53 ± 0.50, and mean critical thinking disposition was 127.52 ± 10.85. Among the dimensions of reflection, “active self-appraisal (SA)” and “reflective with others (RO)” had the highest and lowest means, respectively. The dimensions of critical thinking disposition with the highest and lowest means were related to innovation and intellectual maturity, respectively. Reflective capacity and its dimensions were found to have a direct and statistically significant relationship with critical thinking disposition and its dimensions. Regression analysis results showed that reflective capacity accounts for 28% of students’ critical thinking disposition.

CONCLUSION: The relationship between students’ reflective capacity and their critical thinking disposition has rendered reflection as one of the necessary components of medical education. Thus, determining the learning activities by considering the reflection process and models will be very effective in creating and strengthening critical thinking disposition.

ABSTRACT

BACKGROUND: Electronic platform based-learning for residents is increasing. The aim of this study was to identify the most reliable predictor variables related to the usage of electronic platform-based educational material for radiology residents which can predict a successful multiple-choice test during the academic year.

METHODS: A two year survey was conducted based on the records of electronic platform-based educational material for radiology residents. Radiology resident education was based on the educational content of two educational electronic platform databases named RADPrimer and STATdx (Elsevier, Amsterdam) consisting in evidence-based and expert-vetted summary information to support learning and diagnosing in radiology. A pool of multiple-choice questions was addressed in RADPrimer by each resident after 6 months from the beginning of each academic year, and at the end of the respective residency year as part of end of the year assessment. A per-resident analysis was performed to analyze the correlation between the amount of electronic platform content accessed by residents (measured by total login times, login frequency per month, and the number of per-topic addressed questions) in preparation for the electronic test during the academic year (predictor variables) and per-resident average percentage of correct answers on electronic test (outcome variable). Statistical significance (p < 0.05) was determined using logistic regression and correlation analysis.

RESULTS: Total login times (OR, 3; 95% CI, 2.2 -4), login frequency per month (OR, 4; 95% CI, 3.1-5.3), the number of per-topic addressed questions (OR, 3; 95% CI, 2.2 -4), and the number of topic-verified correct answers to multiple choice test (OR, 30.5; 95% CI, 12.8-80.9) all showed a statistically significant correlation with final percentage of correct answers on final year electronic test.

CONCLUSION: The number of correct answers to multiple choice test was related to the number and frequency of login access, the number of per-topic addressed questions and the number of topic-verified correct answers to multiple choice test. The electronic-based educational material contributes significantly to a successful radiology residency program.

ABSTRACT

BACKGROUND: Deregulation of lncRNAs has been observed in human osteosarcoma. This study explored the diagnostic and prognostic significance of EPB41L4A-AS1 and UNC5B-AS1 in osteosarcoma.

METHODS: Relative levels of EPB41L4A-AS1 and UNC5B-AS1 were detected in osteosarcoma tissue samples and cells. The ability to distinguish osteosarcoma from health was assessed by receiver operating characteristic (ROC) curve construction. Kaplan-Meier (K-M) and Cox proportional-hazards analyses were performed for prognosis factors. The bioinformatics approach was used to identify targeting miRNA for EPB41L4A-AS1 and UNC5B-AS1. Kaplan-Meier survival curves and Whitney Mann U tests were conducted for validating the statistical significance. In cell culture experiments, the influence of EPB41L4A-AS1 and UNC5B-AS1 on proliferation, migration, and invasion of the osteosarcoma cell line was examined by CCK-8 and Transwell assays.

RESULTS: Levels of EPB41L4A-AS1 and UNC5B-AS1 were upregulated in osteosarcoma patients and cells compared with the healthy participants and normal cell lines. EPB41L4A-AS1 and UNC5B-AS1 have a potent ability to distinguish the patients with osteosarcoma from the health. EPB41L4A-AS1 and UNC5B-AS1 levels correlated with SSS stage. Patients with high levels of EPB41L4A-AS1 and UNC5B-AS1 had significantly shorter survival times. EPB41L4A-AS1 and UNC5B-AS1 were independent prognostic indexes for overall survival. miR-1306-5p was a common target for EPB41L4A-AS1 and UNC5B-AS1. A propulsive impact on cell proliferation, migration, and invasion by EPB41L4A-AS1 and UNC5B-AS1 was observed, but can be rescued by miR-1306-5p.

CONCLUSIONS: It was concluded that upregulations of EPB41L4A-AS1 and UNC5B-AS1 expression were diagnostic and prognostic biomarkers for human osteosarcoma. EPB41L4A-AS1 and UNC5B-AS1 contribute to the biological behavior of osteosarcoma via miR-1306-5p.

ABSTRACT

BACKGROUND: Students´ assessment should be carried out in an effective and objective manner, which reduces the possibility of different evaluators giving different scores, thus influencing the qualification obtained and the consistency of education. The aim of the present study was to determine the agreement among four evaluators and compare the overall scores awarded when assessing portfolios of endodontic preclinical treatments performed by dental students by using an analytic rubric and a numeric rating scale.

METHODS: A random sample of 42 portfolios performed by fourth-year dental students at preclinical endodontic practices were blindly assessed by four evaluators using two different evaluation methods: an analytic rubric specifically designed and a numeric rating scale. Six categories were analyzed: radiographic assessment, access preparation, shaping procedure, obturation, content of the portfolio, and presentation of the portfolio. The maximum global score was 10 points. The overall scores obtained with both methods from each evaluator were compared by Student’s t, while agreement among evaluators was measured by Intraclass correlation coefficients (ICC). The influence of the difficulty of the endodontic treatment on the evaluators´ scores was analyzed by one-way ANOVA. Statistical tests were performed at a pre-set alpha of 0.05 using Stata 16.

RESULTS: Difficulty of canal treatment did not influence the scores of evaluators, irrespective of the evaluation method used. When the analytic rubric was used, inter-evaluator agreement was substantial for radiographic assessment, access preparation, shaping procedure, obturation, and overall scores. Inter-evaluator agreement ranged from moderate to fair with the numeric rating scale. Mean higher overall scores were achieved when numeric rating scale was used. Presentation and content of the portfolio showed slight and fair agreement, respectively, among evaluators, regardless the evaluation method applied.

CONCLUSIONS: Assessment guided by an analytic rubric allowed evaluators to reach higher levels of agreement than those obtained when using a numeric rating scale. However, the rubric negatively affected overall scores.

ABSTRACT

BACKGROUND: Bisphosphonates (BPs) are widely used in clinical practice to prevent and treat bone metabolism-related diseases. Medication-related osteonecrosis of the jaw (MRONJ) is one of the major sequelae of BPs use. Early prediction and intervention of MRONJ are of great significance.

METHODS: Ninety-seven patients currently on treatment with BPs or with a history of BPs usage and 45 healthy volunteers undergoing dentoalveolar surgery were included in this study. Participants’ serum Semaphorin 4D (Sema4D) levels were measured and analyzed before participants underwent surgery (T0) and after a 12-month follow-up (T1). Kruskal-Wallis test and ROC analysis were used to examine the predictive effect of Sema4D on MRONJ.

RESULTS: Sema4D levels in serum of patients corresponding to confirmed MRONJ were significantly lower at both T0 and T1 time points compared to non-MRONJ and healthy controls. Sema4D has a statistically predictive effect on the occurrence and diagnosis of MRONJ. Serum Sema4D levels were significantly reduced in MRONJ class 3 patients. MRONJ patients who received intravenous BPs had significantly lower Sema4D levels than those who received oral BPs.

CONCLUSION: Serum Sema4D level has predictive value for the onset of MRONJ in BPs users within 12 weeks after dentoalveolar surgery.
