Gait in children with achondroplasia – a cross-sectional study on joint kinematics and kinetics

BMC Musculoskelet Disord. 2022 Apr 28;23(1):397. doi: 10.1186/s12891-022-05343-4.

ABSTRACT

BACKGROUND: Children with achondroplasia have extreme short stature due to short limbs, as well as several other clinical features that may affect their gait. The purpose of this cross-sectional study was to provide a detailed description of gait in children with achondroplasia compared to age-matched controls.

METHODS: Between the years 2007 and 2010, 16 children with achondroplasia [mean age 9.6 years (range 5-16; six female)] with no previous history of orthopaedic lower limb surgery and 19 age-matched controls conducted three-dimensional (3D) gait analysis at one occasion. The gait analysis rendered pelvis and lower limb joint kinematics and kinetics, and time and distance data. Descriptive statistics, independent samples t-tests, and Fisher’s exact test were used to describe the cohort including gait data and participant characteristics.

RESULTS: Children with achondroplasia had kinematic gait pattern deviations in all three planes, especially in the sagittal plane, when compared to the control group. Peak anterior pelvic tilt and peak ankle dorsiflexion were found to be increased. Increased knee flexion was noted at initial contact and again at terminal stance. During stance, children with achondroplasia had a higher peak hip abduction angle and a higher peak knee varus angle in the frontal plane. In the sagittal plane, kinetic gait pattern deviations were found at the hip, knee, and ankle, consistent with a flexion pattern. Compared to the control group, children with achondroplasia walked with reduced walking speed and step length, and increased cadence. There was no difference in walking speed when leg length was taken into account. Normalised step length and normalised cadence, on the other hand, were found to be increased in children with achondroplasia.

CONCLUSIONS: The observed gait characteristics in children with achondroplasia are related to anatomical attributes and strategies to increase step length, and hence walking speed.

Promoting a sense of belonging, engagement, and collegiality to reduce burnout: a mixed methods study among undergraduate medical students in a non-Western, Asian context

BMC Med Educ. 2022 Apr 28;22(1):327. doi: 10.1186/s12909-022-03380-0.

ABSTRACT

BACKGROUND: Burnout is a psychological condition induced by work-related chronic interpersonal stressors. Interventions creating a sense of belonging and collegiality have been proposed as approaches for alleviating burnout. The current study aimed to: (1) explore the relationships between burnout, sense of belonging (relatedness with others), and work engagement; and (2) identify the key elements perceived by undergraduate medical students as positively contributing to collegiality, engagement, and a sense of belonging, in an undergraduate medical training setting.

METHODS: An exploratory sequential mixed-methods design using questionnaires and semi-structured individual interviews collected quantitative and qualitative data among undergraduate medical students at Mahidol University, Thailand. The Maslach Burnout Inventory-Student Survey questionnaire was used to measure burnout. The Basic Psychological Need Satisfaction at Work Scale (BPNSS-21) and the Utrecht Work Engagement Scale-Student Version (UWESS-9) measured students’ basic psychological needs satisfaction at work and work engagement, respectively. Descriptive statistical analysis and confirmatory factor analysis were performed on BPNSS-21 and UWESS-9 data. Spearman’s correlation coefficient was used to identify the correlation between burnout and other factors. Twenty undergraduate medical students participated in the qualitative study. Qualitative analysis was conducted iteratively using constant comparison and the standard principles of primary, secondary, and tertiary coding for thematic analysis.

RESULTS: Thai versions of the BPNSS-21 and UWESS-9 showed an acceptable fit for the Thai cultural context. Burnout had significant weak inverse associations with engagement (r = – 0.39, p < 0.005) and basic psychological needs satisfaction (r = – 0.37, p < 0.005). Sense of belonging had a significant weak inverse relationship with burnout (r = – 0.25, p < 0.005). The main themes emerging from qualitative analysis were relevant tasks and learning activities, safety in the learning environment, peer interaction, program design factors, dynamics of collegiality while progressing through medical school, and personal stance and social skills.

CONCLUSIONS: Sense of belonging, engagement, and collegiality were related to burnout. The key features for promoting collegiality, the sense of belonging, and engagement were relevant tasks and learning activities, safety in the learning environment, peer interaction, program design factors, dynamics of collegiality while progressing through medical school, and personal stance and social skills.

Potential impacts of synthetic food dyes on activity and attention in children: a review of the human and animal evidence

Environ Health. 2022 Apr 29;21(1):45. doi: 10.1186/s12940-022-00849-9.

ABSTRACT

Concern that synthetic food dyes may impact behavior in children prompted a review by the California Office of Environmental Health Hazard Assessment (OEHHA). OEHHA conducted a systematic review of the epidemiologic research on synthetic food dyes and neurobehavioral outcomes in children with or without identified behavioral disorders (particularly attention and activity). We also conducted a search of the animal toxicology literature to identify studies of neurobehavioral effects in laboratory animals exposed to synthetic food dyes. Finally, we conducted a hazard characterization of the potential neurobehavioral impacts of food dye consumption. We identified 27 clinical trials of children exposed to synthetic food dyes in this review, of which 25 were challenge studies. All studies used a cross-over design and most were double blinded and the cross-over design was randomized. Sixteen (64%) out of 25 challenge studies identified some evidence of a positive association, and in 13 (52%) the association was statistically significant. These studies support a relationship between food dye exposure and adverse behavioral outcomes in children. Animal toxicology literature provides additional support for effects on behavior. Together, the human clinical trials and animal toxicology literature support an association between synthetic food dyes and behavioral impacts in children. The current Food and Drug Administration (FDA) acceptable daily intakes are based on older studies that were not designed to assess the types of behavioral effects observed in children. For four dyes where adequate dose-response data from animal and human studies were available, comparisons of the effective doses in studies that measured behavioral or brain effects following exposure to synthetic food dyes indicate that the basis of the ADIs may not be adequate to protect neurobehavior in susceptible children. There is a need to re-evaluate exposure in children and for additional research to provide a more complete database for establishing ADIs protective of neurobehavioral effects.

Probiotic in the prevention of ventilator-associated pneumonia in critically ill patients: evidence from meta-analysis and trial sequential analysis of randomized clinical trials

BMC Pulm Med. 2022 Apr 28;22(1):168. doi: 10.1186/s12890-022-01965-5.

ABSTRACT

BACKGROUND: Probiotic might have a role in the prevention of ventilator-associated pneumonia (VAP) among mechanically ventilated patients, but the efficacy and safety remained inconsistent. The aim of this systematic review and meta-analysis was to evaluate the efficacy and safety of probiotic (prebiotic, synbiotic) versus placebo in preventing VAP in critically ill patients undergoing mechanical ventilation.

METHODS: PubMed, Embase and the Cochrane library databases were searched to 10 October 2021 without language restriction for randomized or semi-randomized controlled trials evaluating probiotic (prebiotic, synbiotic) vs. placebo in prevention of VAP in critically ill mechanically ventilated patients. The pooled relative risk (RR) along with 95% confidence intervals (CI) were combined using a random-effects model. Furthermore, the trial sequential analysis (TSA) and subgroup analyses were performed. Statistical significance was regarded as P < 0.05.

RESULTS: Twenty-three trials involving 5543 patients were eligible for this meta-analysis. The combined RR of decreasing the risk of VAP by probiotic was 0.67 (0.56, 0.81) for all eligible studies, 0.69 (n = 5136; 95% CI = 0.57 to 0.84; P < 0.01) for adults studies and 0.55 (n = 407; 95%CI = 0.31 to 0.99; P = 0.046) for neonates/children studies. Additionally, the above-mentioned positive finding in 20 adults studies was verified by the results of TSA, subgroup analyses and cumulative meta-analysis. Ample evidences demonstrated a 31% decrease in RR of incidence of VAP was noted when prophylactic probiotic therapy was administrated among adult patients. Finally, there were no effects on the ICU/hospital/28-/90-day mortality, bacteremia, CRBSI, diarrhea, ICU-acquired infections, infectious complications, pneumonia, UTI and wound infection between two groups (P > 0.05 for all).

CONCLUSIONS: Based on the results of our study, the current evidences suggested that prophylactic administration of probiotic might be utilized as a preventive method for VAP in neonates/children and adults patients who required mechanical ventilation. However, further large, high-quality RCTs are warranted to assess the efficacy and safety of probiotic treatment in critically ill patients, especially for the neonates/children studies and the long-term consequences of this therapy.

Evaluating the utility of an international webinar as a platform to educate students and doctors on the UK core surgical training portfolio

BMC Med Educ. 2022 Apr 28;22(1):329. doi: 10.1186/s12909-022-03399-3.

ABSTRACT

BACKGROUND: Core Surgical Training (CST) is a competitive two-year postgraduate training program in the UK that is scored based on three equally weighted stations: management, clinical and portfolio. Preparing a surgical portfolio can start in medical school, however, there is limited guidance on what forms a competitive portfolio with the majority of advice coming from university resources and national societies which are variable throughout the country. Our aim was to assess the utility of a webinar to educate students and doctors on the CST portfolio to address this disparity.

METHODS: Pre- and post-event questionnaires that included demographic data, 10-point Likert scales to self-report confidence on the understanding of the CST portfolio and its domains, and questions on utilising webinars were distributed to attendees. Pre- and post-event responses were paired, and scores were assessed for normality via the Shapiro-Wilk test; the Mann-Whitney U test was used to assess statistical significance. Cohen’s d effect sizes were calculated to report standardised differences between pre-and post-event scores.

RESULTS: A total of 177 participants from over 24 countries responded to both questionnaires. A statistically significant improvement in awareness of how to score maximum points was demonstrated across all nine CST domains (p < 0.0001). Regardless of whether they were UK-based or international, approximately half of the participants stated a preference for a webinar over an in-person format. Interestingly, most attendees did not feel that their university had provided them with adequate information on preparing for a surgical career with over half of the attendees stating that they had to attend events by external organisations to obtain such information.

CONCLUSIONS: This study has demonstrated that a webinar can be effectively utilised to educate students and doctors on the various domains of the CST portfolio and how to maximise points in each section. Such events could address the variability of university resources and national societies across the country and provide equal opportunities for students. Further studies that directly compare webinars with in-person events and investigate long-term outcomes, such as success in CST applications, are required.

Establishing a minimum data set for suicide and attempted suicide registry system in Iran

BMC Public Health. 2022 Apr 29;22(1):857. doi: 10.1186/s12889-022-13276-9.

ABSTRACT

BACKGROUND: Suicidal behavior is a major cause of mortality and disability worldwide. Accurate and consistent collection of data on suicide, suicide ideation, and suicide attempts presents many challenges for public health practitioners, policymakers, and researchers. This study aimed to establish a minimum data set (MDS) for integrating data across suicide registries and other data sources.

METHODS: The MDS proposed in this study was developed in two-stepwise stages. First, an extensive literature review was performed in order to identify the potential data items. Then, we conducted a two-round Delphi stage to reach a consensus among experts regarding essential data items and a supplementary one-round Delphi stage for validating the content of the final MDS by calculating the individual item content validity index (CVI) and content validity ratio (CVR) and using other statistical tests.

RESULTS: After the literature review, 189 data items were extracted and sent to a panel of experts in the form of a questionnaire. In the Delphi stage and CVI calculation, 55 and 10 experts participated in kappa and CVR calculation, respectively. Finally, the MDS of the suicide registry was finalized with 84 data elements that were classified into four categories, including patient profile, socio-economic status, clinical and psychopathological status, and suicide circumstances.

CONCLUSIONS: The suicide MDS can become a standardized and consistent infrastructure for meaningful evaluations, reporting, and benchmarking of suicidal behaviors across regions and countries. We hope this MDS will facilitate epidemiological surveys and support policymakers by providing higher quality data capture to guide clinical practice and improve patient-centered outcomes.

Contribution of portable obstetric ultrasound service innovation in averting maternal and neonatal morbidities and mortalities at semi-urban health centers of Ethiopia: a retrospective facility-based study

BMC Pregnancy Childbirth. 2022 Apr 28;22(1):368. doi: 10.1186/s12884-022-04703-1.

ABSTRACT

BACKGROUND: The maternal and neonatal mortalities in Ethiopia are high. To achieve the Sustainable Development Goals, innovations in ultrasound scanning and surveillance activities have been implemented at health centers for over 2 years. This study aims to estimate the contribution of obstetric ultrasound services on averted maternal and neonatal morbidities and mortalities in Ethiopia.

METHODS: A retrospective facility-based cross-sectional study design was conducted in 25 selected health centers. Data were extracted from prenatal ultrasound registers. SPSS version 25 was used for analysis. To claim statistically significant relationship among sartorial variables, a chi-square test was analyzed and P < 0.05 was the cut-off point.

RESULTS: Over the 2 years, 12,975 pregnant women were scanned and 52.8% of them were residing in rural areas. Abnormal ultrasound was reported in 12.7% and 98.4% of them were referred for confirmation of diagnosis and treatment. The ultrasound service has contributed to the prevention of 1,970 maternal and 19.05 neonatal morbidities and mortalities per 100,000 and 1,000 live births respectively. The averted morbidities and mortalities showed a statistically significant difference among women residing in rural and semi-urban areas, X,2 df (10) = 24.07, P = 0. 007 and X,2 df (5) = 20.87. P = 0.00, 1 respectively.

CONCLUSION: After availing the appropriate ultrasound machines with essential supplies and capacitating mid-level providers, significant number of high-risk pregnant women were identified on time and managed or referred to health facilities with safe delivery services. Therefore, scaling-up limited obstetric ultrasound services in similar setups will contribute to achieving the Sustainable Development Goals by 2030. It is recommended to enhance community awareness for improved utilization of ultrasound services by pregnant women before the 24th week of gestational age.

The diagnostic and predictive potential of personality traits and coping styles in major depressive disorder

BMC Psychiatry. 2022 Apr 28;22(1):301. doi: 10.1186/s12888-022-03942-y.

ABSTRACT

BACKGROUND: Major depressive disorder (MDD) is a global public health concern that is notably underdiagnosed and undertreated due to its complexity and subjective diagnostic methods. A holistic diagnostic procedure, which sufficiently considers all possible contributors to MDD symptoms, would improve MDD diagnosis and treatment. This study aims to explore whether personality and coping styles can predict MDD status and differentiate between depressed patients and healthy individuals.

METHODS: Seventy healthy controls (N = 54 females) were matched to 70 MDD patients for age, sex, ethnicity, and years of education. MDD severity was measured using the Hamilton Depression Rating Scale, while personality traits and coping styles were measured by the Ten-Item Personality (TIPI) and Brief COPE questionnaires, respectively. Logistic regression analyses were conducted to investigate the diagnostic and predictive potential of personality and coping styles. Receiver operating characteristic (ROC) analyses were also conducted to examine their discriminative ability to distinguish between depressed and healthy individuals.

RESULTS: Introversion, lack of organisation skills, and neuroticism were statistically significant in predicting MDD status. Dysfunctional coping strategies, such as denial and self-blame, were also shown to significantly predict MDD status. ROC analyses found both the TIPI questionnaire (AUC = 0.90), and dysfunctional coping (as measured by Brief COPE) (AUC = 0.90) to be excellent predictors of MDD.

CONCLUSIONS: Our findings demonstrate the diagnostic and predictive potential of personality and coping styles for MDD in the clinical setting. They also demonstrate the remarkable ability of personality and coping styles to differentiate between depressed patients and healthy controls.

Cognitive-behavioral group therapy in major depressive disorder with focus on self-esteem and optimism: an interventional study

BMC Psychiatry. 2022 Apr 28;22(1):299. doi: 10.1186/s12888-022-03918-y.

ABSTRACT

BACKGROUND: Major depressive disorder is a common psychological condition that can lead to negative individual and social consequences, the management of which is very important in treating the patients. The present study aimed to determine the effect of cognitive-behavioral group therapy on self-esteem and optimism in patients with major depressive disorder.

METHODS: This is a single-blinded, randomized controlled trial in which a total of 64 patients with major depressive disorder were recruited using convenience sampling and then randomly assigned to two groups of Cognitive-Behavioral Group Therapy (CBGT) and Treatment-As-Usual (TAU). Data collection tools consisted of a demographic questionnaire, the Rosenberg Self-Esteem Scale (RSES), and the Revised Life Orientation Test (LOT-R). In the pretest stage, participants in both groups completed the above questionnaires before the intervention. Patients in the CBGT group received eight 90-min sessions of cognitive-behavioral therapy during four weeks (two sessions a week). Then participants re-completed RSES and LOT-R immediately, three months, and six months after the intervention. Data were analyzed with SPSS software version 16.0 using chi-squared test, independent-samples t-test, and repeated measures Analysis of Variance. The significance level (p-value) was considered to be less than 0.05.

RESULTS: It was indicated that there was a statistically significant difference in the mean scores of self-esteem and optimism between the two groups immediately, three months, and six months after the intervention (p < .05). The mean scores of self-esteem and optimism in the CBGT group increased significantly after the intervention compared to before it, although these scores gradually decreased over the three measurement time points after the intervention.

CONCLUSIONS: Based upon the results, it was concluded that the level of optimism and self-esteem increased significantly in the CBGT group after the intervention, although the levels of the above variables dropped again in the long run after the intervention due to the discontinuity of CBGT sessions. Therefore, it is necessary to take particular measures to regularly hold the sessions of CBGT for patients with major depressive disorder.
