ABSTRACT

BACKGROUND: Empathy is one of the fundamental factors enhancing the therapeutic effects of physician-patient relationships, but there has been no relevant research in China on the pediatric resident physicians’ capacity for empathy or the influencing factors.

METHODS: A mixed-methods study was undertaken. The student version of the Jefferson Scale of Empathy was used to assess 181 postgraduate residents at Shanghai Children’s Medical Center and Shanghai Children’s Hospital. Differences in empathy ability among pediatric resident physicians of different genders and specialties were analyzed using independent sample t-tests and Mann-Whitney U tests. A one-way analysis of variance was used to analyze the differences in empathy ability at different educational levels and years of medical residency training. Seven third-year postgraduate pediatric residents from Shanghai Children’s Medical Center participated in semi-structured interviews exploring the influencing factors. We analyzed the interview transcripts using thematic analysis.

RESULTS: The scale was completed by 154 pediatric residents. No statistically significant differences in empathy were found between educational level, postgraduate year, gender, or specialty. The factors influencing empathy in doctor-patient communication included the person who accompanied the child to see the doctor, how the children cooperated with doctors for medical treatment, the volume of pediatric outpatient and emergency visits, and the physician’s ability to withstand pressure. All interviewed resident physicians regarded learning empathy as important but rarely spent extra time learning it.

CONCLUSIONS: The evaluation results of resident physicians on changes in empathy after improving clinical abilities vary according to their understanding of empathy, and the work environment has an important impact on pediatricians’ empathy ability. Their empathy score is relatively low, and this requires exploration and intervention.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has significantly impacted individuals with chronic conditions. This investigation assessed the quality of care provided to pediatric and adolescent patients with juvenile idiopathic arthritis (JIA) during the pandemic in Thailand.

METHODS: This cross-sectional analysis enrolled JIA patients aged ≤ 18 years at an academic tertiary care facility from April 2022 to March 2023. Retrospective reviews were performed, complemented by patient and caregiver questionnaires to assess the pandemic’s impact on care quality.

RESULTS: Seventy JIA patients (37 males, 33 females) with a mean age of 13.5 ± 3.1 years were included. A total of 41.4% of the caregivers reported negative impacts on JIA care due to the pandemic and the lockdown, and 31.4% of the patients experienced pandemic-related anxiety. A comparison between the pandemic and prepandemic periods revealed a higher incidence of active disease, although the difference was statistically nonsignificant (37.1% vs 14.2%, p = 0.106). Nonadherence significantly predicted active disease status (adjusted OR 15.04, 95% CI 2.48-91.15, p = 0.03). COVID-19 vaccinations were administered to 85.7% of patients; 52.8% of whom contracted mild COVID-19. Most patients (71.4%) postponed clinic visits; 36% due to lockdowns and 28% due to concerns about COVID-19 exposure in healthcare settings. The majority of patients received telephone JIA management advice from rheumatologists during the lockdown (91.4%).

CONCLUSIONS: The COVID-19 pandemic and associated lockdown measures affected the care of JIA patients, impacting both physical and mental health. Nonadherence was a critical factor in disease flare-ups. Telemedicine is indispensable for patient care.

ABSTRACT

Healthcare is awash with numbers, and figuring out what knowledge these numbers might hold is worthwhile in order to improve patient care. Numbers allow for objective mathematical analysis of the information at hand, but while mathematics is objective by design, our choice of mathematical approach in a given situation is not. In prehospital and critical care, numbers stem from a wide range of different sources and situations, be it experimental setups, observational data or data registries, and what constitutes a “good” statistical analysis can be unclear. A well-crafted statistical analysis can help us see things our eyes cannot, and find patterns where our brains come short, ultimately contributing to changing clinical practice and improving patient outcome. With increasingly more advanced research questions and research designs, traditional statistical approaches are often inadequate, and being able to properly merge statistical competence with clinical knowhow is essential in order to arrive at not only correct, but also valuable and usable research results. By marrying clinical knowhow with rigorous statistical analysis we can accelerate the field of prehospital and critical care.

ABSTRACT

RATIONALE: Research studies typically quantify acute respiratory exacerbation episodes (AECOPD) among people with chronic obstructive pulmonary disease (COPD) based on self-report elicited by survey questionnaire. However, AECOPD quantification by self-report could be inaccurate, potentially rendering it an imprecise tool for identification of those with exacerbation tendency.

OBJECTIVE: Determine the agreement between self-reported and health records-documented quantification of AECOPD and their association with airway inflammation.

METHODS: We administered a questionnaire to elicit the incidence and severity of respiratory exacerbations in the three years preceding the survey among current or former heavy smokers with or without diagnosis of COPD. We then examined electronic health records (EHR) of those with COPD and those without (tobacco-exposed persons with preserved spirometry or TEPS) to determine whether the documentation of the three-year incidence of moderate to very severe respiratory exacerbations was consistent with self-report using Kappa Interrater statistic. A subgroup of participants also underwent bronchoalveolar lavage (BAL) to quantify their airway inflammatory cells. We further used multivariable regressions analysis to estimate the association between respiratory exacerbations and BAL inflammatory cell composition with adjustment for covariates including age, sex, height, weight, smoking status (current versus former) and burden (pack-years).

RESULTS: Overall, a total of 511 participants completed the questionnaire, from whom 487 had EHR available for review. Among the 222 participants with COPD (70 ± 7 years-old; 96% male; 70 ± 38 pack-years smoking; 42% current smoking), 57 (26%) reported having any moderate to very severe AECOPD (m/s-AECOPD) while 66 (30%) had EHR documentation of m/s-AECOPD. However, 42% of those with EHR-identified m/s-AECOPD had none by self-report, and 33% of those who reported m/s-AECOPD had none by EHR, suggesting only moderate agreement (Cohen’s Kappa = 0.47 ± 0.07; P < 0.001). Nevertheless, self-reported and EHR-identified m/s-AECOPD events were both associated with higher BAL neutrophils (ß ± SEM: 3.0 ± 1.1 and 1.3 ± 0.5 per 10% neutrophil increase; P ≤ 0.018) and lymphocytes (0.9 ± 0.4 and 0.7 ± 0.3 per 10% lymphocyte increase; P ≤ 0.041). Exacerbation by either measure combined was associated with a larger estimated effect (3.7 ± 1.2 and 1.0 ± 0.5 per 10% increase in neutrophils and lymphocytes, respectively) but was not statistically significantly different compared to the self-report only approach. Among the 184 TEPS participants, there were fewer moderate to very severe respiratory exacerbations by self-report (n = 15 or 8%) or EHR-documentation (n = 9 or 5%), but a similar level of agreement as those with COPD was observed (Cohen’s Kappa = 0.38 ± 0.07; P < 0.001).

DISCUSSION: While there is modest agreement between self-reported and EHR-identified m/s-AECOPD, events are missed by relying on either method alone. However, m/s-AECOPD quantified by self-report or health records is associated with BAL neutrophilia and lymphocytosis.

ABSTRACT

PURPOSE: The task faced by surgeons becomes significantly more challenging when they encounter lower extremity bone defects due to a variety of causes requiring lengthening. The most discussed and successful approach is the Illizarov technique, or lengthening over a nail (LON):distraction osteogenesis is also widely performed with monoliteral external fixators and intramedullarylengthening nails have increasingly been used in the last decade.

METHODS: The data were collected from PubMed, Cochrane Library, Embase, and the Web of Science for all available studies comparing the outcomes of Ilizarov technique alone and LON technique (from January 1, 1997, to November 30, 2023). The outcomes of interest encompassed the external fixation index (EFI) (month/cm), mean duration of follow-up (MFT) (month), length gained (LG) (cm), consolidation index (CIx) (month/cm), and bone healing index (BHI) (month/cm).Complications include pin tract infection rate (PTI), axial deviation rate (AD), occurrence of intramedullary infection (II), delayed consolidation rate (DC), as well as data categorized into three levels of problems, obstacles, and sequelae based on the severity of complications.Two reviewers independently assessed each study for quality and extracted data. The case-control or respective cohort studies were evaluated using the Newcastle-Ottawa scale (NOS) to determine their techniqueological rigor.The Cochrane Collaboration’s risk assessment tool was employed to perform quality evaluations for randomized controlled trials.

RESULTS: This review included thirteen studies comprising a total of 629 patients.The external fixation index (month/cm) was significantly smaller in the LON technique compared to the Ilizarov technique alone [Mean Difference(MD) = -29.59, 95% CI -39.68–19.49, P < 0.00001].In terms of the mean follow-up time(month) (MD = -0.92, 95% CI -3.49-1.65, P = 0.57), length gained (cm) (MD = -0.87, 95%CI -2.80-1.07, P = 0.38), consolidation index (month/cm) (MD = 0.66, 95% CI -3.44-4.77, P = 0.75), and bone healing index (month/cm) (MD = -3.33, 95% CI -13.07-6.41, P = 0.5), there were no significant differences observed. The LON technique exhibited a lower incidence of axial deviation [Odds Ratio(OR) = 0.06, 95%CI 0.03-0.16, P < 0.00001] and pin tract infection (OR = 0.30, 95%CI 0.18-0.50, P < 0.00001) compared to the Ilizarov technique alone.The remaining complications, such as intramedullary infection rate (OR = 0.93, 95%CI 0.42-2.06, P = 0.85) and delayed consolidation rate(OR = 0.61, 95%CI 0.20-1.86, P = 0.38), did not exhibit statistically significant differences.Our findings demonstrated that the LON technique results in lower incidences of problems (38.5%vs.58.6%) and sequelae (16.6% vs.30.9%) when compared to the Ilizarov technique alone. However, the rates of obstacles (32.4% vs.32.3%) were comparable between the two methods.

CONCLUSIONS: Our findings indicate that patients treated with the LON technique experienced significantly shorter external fixation durations and a lower incidence of complications (e.g., pin tract infections and axial deviation) compared to those treated with the Ilizarov technique alone. Other outcome metrics showed no significant differences between the two techniques. However, the LON technique offers substantial benefits, including reduced external fixation times and increased comfort, which enhance patient compliance. In conclusion, the LON technique is a safe, reliable, and effective method for treating tibial and femoral defects.

ABSTRACT

BACKGROUND: A dolutegravir (DTG)-based antiretroviral regimen has been rolled out for pregnant women in low- and middle-income countries since 2020. However, available safety data are limited to a few clinical trials and observational studies. Hence, we present real-world pregnancy and birth outcome safety data from a large sample multicenter cohort study in Ethiopia.

METHODS: A retrospective cohort study was conducted in fourteen hospitals across Ethiopia from 2017 to 2022. HIV-infected pregnant women were followed from the date of prevention of mother-to-child transmission (PMTCT) care enrolment until the infant was 6-8 weeks old. The primary safety outcome was a composite of adverse pregnancy events comprising spontaneous abortion, intrauterine fetal death (IUFD) before onset of labor, preterm birth, and maternal death. Additionally, a composite adverse birth outcome was assessed, comprising intrapartum fetal demise, low birth weight, and neonatal death. Finally, a composite of adverse pregnancy or birth outcome was also investigated. The exposure of interest was the antiretroviral treatment (ART) regimen used during pregnancy for PMTCT of HIV.

RESULTS: During the study period, 2643 women were enrolled in routine PMTCT care. However, 2490 (92.2%) participants were eligible for the study. A total of 136/1724 (7.9%, 95% CI: 6.7-9.3%) women experienced adverse pregnancy outcomes. Fewer women in the DTG-based group (5.4%, 95% CI: 3.7-7.5%) had adverse pregnancy outcomes than in the Efavirenz (EFV)-based group (8.3%, 95% CI: 6.6-10.3%), P = 0.004. After controlling for baseline differences, the DTG group had a 43% lower risk of adverse pregnancy outcomes (adjusted odd ratio (AOR), 0.57; 95% CI, 0.32-0.96%) and a 53% lower risk of preterm birth (AOR, 0.47; 95% CI, 0.22-0.98%) compared to the EFV group. A total of 103/1616 (6.4%, 95% CI: 5.2-7.7%) women had adverse birth outcomes. Although the difference was not statistically significant, fewer women in the DTG group (30/548; 5.5%, 95% CI: 3.7-7.7%) than in the EFV group (57/830; 6.9%, 95% CI: 5.2-8.8%) had adverse birth outcomes.

CONCLUSIONS: In this study, we observed that DTG-based regimens were associated with better pregnancy and birth outcome safety profiles, reaffirming the WHO recommendation. However, a prospective study is recommended to assess uncaptured maternal and perinatal adverse outcomes, such as congenital abnormalities, and infant growth and neurocognitive development.

ABSTRACT

BACKGROUND: The proportion of nitrogen (N) derived from the atmosphere (Ndfa) is a fundamental component of the plant N demand in legume species. To estimate the N benefit of grain legumes for the subsequent crop in the rotation, a simplified N balance is frequently used. This balance is calculated as the difference between fixed N and removed N by grains. The Ndfa needed to achieve a neutral N balance (hereafter $\theta$ ) is usually estimated through a simple linear regression model between Ndfa and N balance. This quantity is routinely estimated without accounting for the uncertainty in the estimate, which is needed to perform formal statistical inference about $\theta$ . In this article, we utilized a global database to describe the development of a novel Bayesian framework to quantify the uncertainty of $\theta$ . This study aimed to (i) develop a Bayesian framework to quantify the uncertainty of $\theta$ , and (ii) contrast the use of this Bayesian framework with the widely used delta and bootstrapping methods under different data availability scenarios.

RESULTS: The delta method, bootstrapping, and Bayesian inference provided nearly equivalent numerical values when the range of values for Ndfa was thoroughly explored during data collection (e.g., 6-91%), and the number of observations was relatively high (e.g., $\ge 100$ ). When the Ndfa tested was narrow and/or sample size was small, the delta method and bootstrapping provided confidence intervals containing biologically non-meaningful values (i.e. < 0% or > 100%). However, under a narrow Ndfa range and small sample size, the developed Bayesian inference framework obtained biologically meaningful values in the uncertainty estimation.

CONCLUSION: In this study, we showed that the developed Bayesian framework was preferable under limited data conditions ─by using informative priors─ and when uncertainty estimation had to be constrained (regularized) to obtain meaningful inference. The presented Bayesian framework lays the foundation not only to conduct formal comparisons or hypothesis testing involving $\theta$ , but also to learn about its expected value, variance, and higher moments such as skewness and kurtosis under different agroecological and crop management conditions. This framework can also be transferred to estimate balances for other nutrients and/or field crops to gain knowledge on global crop nutrient balances.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has led to the broad acceptance of distance education (DE), with university professors and students conducting the teaching-learning process remotely from their homes. The propose of this study to investigate the prevalence of musculoskeletal disorders (MSDs) before and during the COVID-19 pandemic and identify risk factors associated with DE that may contribute to an increased incidence of these disorders among university professors.

METHODS: This cross-sectional analytical study took a comparative approach and involved 310 university professors in Iran. Data were gathered using an online questionnaire. Initially, demographic and occupational information of the professors, hours of physical activity, and hours spent using electronic devices were recorded. Participants were then asked to report MSDs in various body areas throughout the previous year and the previous seven days. Finally, MSDs risk factors such as workstation ergonomics during computer, laptop, smartphone, and tablet use, as well as working postures during online teaching or offline content development during the COVID-19 pandemic, were examined.

RESULTS: The majority of the participants were male (66.13%), with a PhD (46.77%) and a faculty member position (74.2%). On average, the use of computers and laptops increased by 2.67 h and 2.72 h, respectively, during the pandemic compared to before the pandemic. This increase was statistically significant (P < 0.001). MSDs incidence increased significantly before and during the COVID pandemic was observed in the areas of the neck, shoulders, lower and upper back, arms, forearms, wrists and fingers (P < 0.05). The highest cumulative incidence (Cin) of MSDs was related to the neck (Cin = 24.20%), upper back (Cin = 21.29%), low back (Cin = 18.06%) and fingers (Cin = 16.13%). The prevalence of MSDs during the COVID pandemic was significantly associated with employment status (P = 0.042), work experience (P = 0.016), age (P = 0.027), increase in the use of computers/ laptops (P < 0.001), decrease of the smartphone/tablet distance from the body (P = 0.047), workstation (smartphone-tablet, computer, laptop) (P < 0.05), head position (smartphone-tablet) (P = 0.029), display height (computer/laptop) (P = 0.045) and physical activity (P = 0.006).

CONCLUSIONS: It appears that the increased duration of smartphone, computer, and laptop use, combined with decreased physical activity and detrimental changes in ergonomic conditions of workstations during the quarantine period caused by the COVID-19 pandemic, has resulted in a shift from dynamic to static tasks and an increase in the prevalence and incidence of MSDs among university professors.

ABSTRACT

BACKGROUND: Pediatrics is one of the most important medical specialties in the Kingdom of Saudi Arabia) KSA) since it serves a large population. Therefore, the pediatrics residency program is considered one of the most important and competitive programs. Obtaining acceptance in Saudi programs depends mainly on the Saudi Commission for Health Specialties (SCFHS) score, then the applicant enrolls to do the interviews with the training centers in the accepted region. This study aimed to evaluate the factors used by pediatric program directors (PD) in accepting applicants in their pediatric residency program in KSA.

METHODS: In this cross-sectional study, an online questionnaire consisting of 49 items was distributed among 76 current and former pediatric PDs in KSA. Participants were selected via non-probability convenience sampling. Data were collected and analyzed using the Social Sciences Statistical Package (SPSS version 26).

RESULTS: Of the sample of PD studied, males represented 77.6%, while females represented 22.4%. Most of the PDs were over 50 years old. Most of them were former pediatric PDs (71.1%). The current study found that the Saudi Medical Licensing Exam was the most important factor [3.87 (0.89)] followed by services and electives [3.86 (0.65)], research [3.84 (0.83)], interview [3.77 (0.89)], GPA [3.50 (0.62)], and letter of recommendation [3.39 (0.76)].

CONCLUSIONS: For those interested in pediatrics residency programs in KSA, this study recommends that seeking a high Saudi Medical Licensing Exam (SMLE) score, taking pediatric elective rotations during internship, and acquiring excellent basic knowledge in research were the most important aspects of pediatrics residency selection from the pediatrics PD’s perspective.

ABSTRACT

BACKGROUND: A predictive assay for late radiation toxicity would allow more personalized treatment planning, reducing the burden of toxicity for the more sensitive minority, and improving the therapeutic index for the majority. In a previous study in prostate cancer patients, the γ-H2AX foci decay ratio (γ-FDR) was the strongest predictor of late radiation toxicity. The current study aimed to validate this finding in a more varied group of patients with pelvic cancer. Additionally, the potential correlation between the γ-FDR and patient-reported outcomes was investigated.

METHODS: Prostate and gynecological cancer patients with ≥ 24 months of follow-up were included in the current analysis. Toxicity was evaluated by physician (CTCAE version 4) and patient (EORTC questionnaires). γ-FDRs were determined in ex vivo irradiated lymphocytes. Correlation between γ-FDR and toxicity was assessed using both linear and logistic regression analyses. The highest toxicity grade recorded during follow-up was used. The association between global quality of life and γ-FDR was tested by comparing the change in quality of life over time in patients with γ-FDR < or ≥ 3.41, a previously established threshold.

RESULTS: Eighty-eight patients were included. Physician-assessed and patient-reported cumulative grade ≥ 2 toxicity was 25% and 29%, respectively; which is much lower than in the previous cohort (i.e., 51% CTCAE grade ≥ 2). Patients with toxicity exhibited less favorable dose-volume parameters. In men, these parameters showed significant improvement compared to the previous cohort. The proportion of patients with a low γ-FDR increased with severity of toxicity, but this trend was not statistically significant. In addition, a γ-FDR < 3.41 was not correlated with the development of moderate to severe toxicity. Post-treatment decline in global quality of life was minimal, and similar for patients with γ-FDR < or ≥ 3.41.

CONCLUSIONS: In the present study, the γ-H2AX foci decay ratio could not be validated as a predictor of late radiation toxicity in patients with pelvic cancer. Improved radiotherapy techniques with smaller irradiated bladder and bowel volumes have probably resulted in less toxicities. Future studies on genetic markers of toxicity should be powered on these lower incidences. We further recommend taking persistency, next to severity, into consideration.
