ABSTRACT

BACKGROUND: Daily more than 3,000 children are injured or killed on the road, often along the school route. Road traffic crashes and resulting injuries are preventable. More can be done to reduce injuries and save lives. Traffic Conflict Techniques (TCTs) are simple methods of collecting observational data to evaluate the effectiveness of road safety interventions through counting and analyzing traffic conflicts. A TCT Toolkit was developed and piloted to analyze pedestrian-vehicle traffic conflicts in school zones in low- and middle-income countries.

METHODS: Three non-governmental organizations in Ghana, Vietnam, and Mexico applied three TCTs from the TCT Toolkit to collect traffic conflict data before (pre-intervention) and after (post-intervention) road safety intervention implementation. As the number of traffic conflicts was often less than 100, confidence intervals (CIs) based on gamma distributions were calculated for the traffic conflict rate. Using the calculated traffic conflict rate, the difference between pre- and post-intervention rates was assessed by determining overlap of the CIs. When CIs did not overlap, the difference was said to be statistically significant at the 0.05 level.

RESULTS: For each method, results indicated a decrease in traffic conflicts between pre- and post-intervention data collection periods. Pre- and post-intervention traffic conflict rates with non-overlapping CIs demonstrated the results were statistically significant, providing evidence that the road safety interventions were effective.

CONCLUSIONS: TCTs are relatively low-cost and simple techniques that provide an opportunity to base road safety improvement decisions on real-world data. TCTs are effective in objectively evaluating road safety interventions and can help decision-makers evaluate strategies for improving road safety, preventing injuries and saving lives.

ABSTRACT

BACKGROUND: The outbreak of the Corona virus (COVID-19) pandemic led to a sharp rise in morbidity and hospitalizations, and a significant therapeutic burden fell on intensive care units (ICUs). Intensive care nurses reported physical and emotional stress in response to the extra workload caused by caring for critically ill COVID-19 patients. However, at the time of publication of the study, to the best of our knowledge there have been no studies that examined uncertainty, stress, or hope in the context of functioning among intensive care nurses.

AIM: To examine: (a) the challenges of operating and managing intensive care units during the COVID-19 pandemic among nurse managers in intensive care units, and (b) the relationships between uncertainty, stress, burnout, hope, and professional functioning among intensive care nurses during the COVID-19 pandemic.

DESIGN: This mixed-methods study was conducted in intensive care units (ICUs) at a large tertiary medical center in Israel, during February-May 2021.

METHODS: The data were collected in two phases. In the first phase, qualitative data were collected from focus groups attended by 15 senior managerial nurses. The second phase involved a cross-sectional study among 100 staff nurses working in 5 ICUs. The data were collected using a structured questionnaire.

RESULTS: Qualitative data analysis revealed two main themes: (a) challenges of the COVID-19 pandemic and (b) positive aspects of the COVID-19 pandemic. The nurses reported high levels of burnout, emotional stress and uncertainty, but moderate State Hope Scale scores, and moderate levels of professional functioning. There were no statistical differences in study variables by exposure to COVID-19 patients. State Hope Scale levels, uncertainty, and burnout variables contributed significantly and explained 46% of the variance of the professional functioning.

CONCLUSIONS: The intensity of the experiences and psych-social phenomena, is not affected by exposure to treatment of COVID-19 patients. The relationships between the study variables emphasize the importance of initiated and ongoing interventions to reduce uncertainty, address burnout, and strengthen hope. Improvement in these indices may lead to better ICU nurses’ professional functioning and their work life well-being.

ABSTRACT

OBJECTIVE: To introduce a novel analytical approach for randomized controlled trials that are underpowered because of low participant enrollment or engagement.

DATA SOURCES: Reanalysis of data for 805 patients randomized as part of a pilot complex care intervention in 2015-2016 in a large delivery system. In the pilot randomized trial, only 64.6% of patients assigned to the intervention group participated.

STUDY DESIGN: A case study and simulation. The “Distillation Method” capitalizes on the frequently observed correlation between the probability of subjects’ participation or engagement in an intervention and the magnitude of benefit they experience. The novel method involves three stages: first, it uses baseline covariates to generate predicted probabilities of participation. Next, these are used to produce nested subsamples of the randomized intervention and control groups that are more concentrated with subjects who were likely to participate/engage. Finally, for the outcomes of interest standard statistical methods are used to re-evaluate intervention effectiveness in these concentrated subsets.

DATA EXTRACTION METHODS: We assembled secondary data on patients who were randomized to the pilot intervention, for one year prior to randomization and two follow-up years. Data included program enrollment status, membership data, demographics, utilization, costs, and clinical data.

PRINCIPAL FINDINGS: Using baseline covariates only, Generalized Boosted Regression Models predicting program enrollment performed well (AUC 0.884). We then distilled the full randomized sample to increasing levels of concentration and re-analyzed program outcomes. We found statistically significant differences in outpatient utilization and emergency department utilization (both follow-up years), and in total costs (follow-up year two only) at select levels of population concentration.

CONCLUSIONS: By offering an internally valid analytic framework, the Distillation Method can increase power to detect effects by redefining the estimand to subpopulations with higher enrollment probabilities and stronger average treatment effects while maintaining the original randomization.

ABSTRACT

BACKGROUND: Mesenchymal stromal cells (MSCs) therapy for acute respiratory distress syndrome (ARDS) is an emerging treatment, but most of the current trials of MSCs stay in the animal experimental stage, and the safety and efficacy of MSCs in clinical application are not clear. We aimed to analyze the safety, efficacy and biomarkers of mesenchymal stromal cells in the treatment of ARDS.

METHODS: For this systematic review and meta-analysis, we searched PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of science, CNKI, VIP and Wan Fang data, studies published between database inception and Mar 17, 2022. All randomized controlled trials (RCT) of stem cell interventions for ARDS were included, without language or date restrictions. We did separate meta-analyses for mortality, subjects with adverse events (AEs) and subjects with serious adverse events (SAEs). Since the trials data are dichotomous outcomes, the odds ratio (OR) is adopted for meta-analysis. The quality of the evidence was assessed with the Cochrane risk of bias tool.

FINDINGS: In total, 5 trials involving 171 patients with ARDS were included in this meta-analysis. A total of 99 individuals were randomly assigned to receive MSCs treatment, and 72 were randomly assigned to receive placebo treatment. Treatment with MSCs appeared to increase the occurrence of adverse events, but this result was not statistically significant (OR, 1.58; 95%CI, 0.64-3.91; P = 0.32). The occurrence of serious adverse events was lower in the MSCs group than in the placebo group (OR, 0.57; 95%CI, 0.14-2.32; P = 0.43); there seems to be no significant difference between the two groups in terms of 28 days mortality (OR, 0.93; 95%CI, 0.45-1.89); oxygenation index and biomarkers showed a tendency to improve in treatment, but there was a lack of more statistically significant clinical evidence to support them.

INTERPRETATION: Based on the current clinical trials, MSCs intervention has some safety for ARDS patients, but its effectiveness and predictive value of airspace biomarkers need to be determined by more large-scale, standard randomized controlled trials.

ABSTRACT

BACKGROUND: Schistosomiasis and soil-transmitted helminths (STHs) contribute high disease burdens amongst the neglected tropical diseases (NTDs) and are public health problems in Angola. This study reports the prevalence, intensity and risk factors for schistosomiasis and STH infection in Huambo, Uige and Zaire provinces, Angola, to inform a school-based preventive chemotherapy program.

METHODS: A two-stage cluster design was used to select schools and schoolchildren to participate in parasitological and water, sanitation and hygiene (WASH) surveys across Huambo, Uige, and Zaire provinces. Point-of-care circulating cathodic antigen and urinalysis rapid diagnostic tests (RDTs) were used to determine the prevalence of Schistosoma mansoni and S. haematobium, respectively. Kato-Katz was used to identify and quantify STH species and quantify and compare with RDTs for S. mansoni. Urine filtration was used to quantify and compare with RDTs for S. haematobium. Descriptive statistics were used for prevalence and infection intensity of schistosomiasis and STH infection. Performance of RDTs was assessed through specificity and Cohen’s Kappa agreement with microscopy. A multivariate regression analysis was used to determine demographic and WASH factors associated with schistosomiasis and STH infection.

RESULTS: A total 575 schools and 17,093 schoolchildren participated in the schistosomiasis survey, of which 121 schools and 3649 schoolchildren participated in the STH survey. Overall prevalence of S. mansoni was 21.2% (municipality range 0.9-74.8%) and S. haematobium 13.6% (range 0-31.2%), with an overall prevalence of schistosomiasis of 31.4% (range 5.9-77.3%). Overall prevalence of Ascaris lumbricoides was 25.1% (range 0-89.7%), hookworm 5.2% (range 0-42.6%), and Trichuris trichiura 3.6% (range 0-24.2%), with an overall prevalence of STH infection of 29.5% (range 0.8-89.7%). Ecological zone and ethnicity were factors associated with schistosomiasis and STH infection, with older age and female sex additional risk factors for S. haematobium.

CONCLUSIONS: Most municipalities met World Health Organization defined prevalence thresholds for a schistosomiasis preventive chemotherapy program. A STH preventive chemotherapy program is indicated for nearly all municipalities in Uige and select municipalities in Huambo and Zaire. The association between ecological zone and ethnicity with schistosomiasis and STH infection necessitates further evaluation of home and school environmental, sociodemographic and behavioural factors to inform targeted control strategies to complement preventive chemotherapy programs.

ABSTRACT

BACKGROUND: Hyperinsulinism hyperammonemia (HI/HA) syndrome is caused by activating mutations in GLUD1, encoding glutamate dehydrogenase (GDH). Atypical absence seizures and neuropsychological disorders occur at high rates in this form of hyperinsulinism. Dysregulated central nervous system (CNS) glutamate balance, due to GDH overactivity in the brain, has been hypothesized to play a role. This study aimed to describe the neurologic phenotype in HI/HA syndrome and investigate CNS glutamate levels using glutamate weighted chemical exchange saturation transfer magnetic resonance imaging (GluCEST MRI). In this cross-sectional study, 12 subjects with HI/HA syndrome had plasma ammonia measurement, self- or parent-completed neurocognitive assessments, electroencephalogram (EEG), and GluCEST MRI at 7 T performed. GluCEST MRI measures were compared to a historic reference population of 10 healthy adults.

RESULTS: Subjects were five males and seven females with median age of 25.5 years. Seventy-five percent of subjects reported a history of neurodevelopmental problems and 42% had neurocognitive assessment scores outside the normal range. Fifty percent had interictal EEG findings of generalized, irregular spike and wave discharges. Higher variability in hippocampal GluCEST asymmetry (p = 0.002), and in peak hippocampal GluCEST values (p = 0.008), was observed in HI/HA subjects (n = 9 with interpretable MRI) compared to the healthy reference population (n = 10).

CONCLUSIONS: The high prevalence of abnormal neurocognitive assessment scores and interictal EEG findings observed highlights the importance of longitudinal neuropsychological assessment for individuals with HI/HA syndrome. Our findings demonstrate the potential application of GluCEST to investigate persistent knowledge gaps in the mechanisms underlying the unique neurophenotype of this disorder.

ABSTRACT

BACKGROUND: Physical activity (PA) participation among youth tends to be insufficient and is prone to decline with age. In Australia, this decline has been shown to particularly occur in the domain of non-organized PA (e.g. active play and informal sport) between childhood and adolescence. However, information about changes in more specific groupings of activities within non-organized PA (i.e. subdomains) is needed, as this could support more targeted intervention strategies. This study aimed to investigate changes in the duration of specific subdomains of non-organized PA between late childhood (10-11 years) and early adolescence (12-13 years) in Australia, as well as whether these changes are moderated by sex.

METHODS: Data were sourced from Waves 6 and 7 of the Longitudinal Study of Australian Children (n = 3614). Youth time-use diaries (24-h) were used to measure the duration of eight subdomains of non-organized PA at both waves (athletics/gymnastics, ball sports, cycling/motor/roller sports, fitness/gym/exercise, martial arts/dancing, water/ice/snow sports, active play and other outdoor/nature PA). Multilevel mixed modelling was used to explore longitudinal changes between waves and the potential moderation effect of sex.

RESULTS: Active play declined the most of all subdomains (β = -20.5 min/day; 95% CI = -23.4, -17.6, p < 0.001). A smaller decline was observed in the subdomain of non-organized ball sports (β = -4.1 min/day; 95% CI = -5.9, -2.3, p < 0.001). Other subdomains remained stable or had only very small changes in participation. The decline in active play was moderated by sex, with a steeper decline among girls. No other notable moderation effects were observed.

CONCLUSIONS: Future studies may seek to explore and test the acceptability of PA promotion strategies to encourage active play participation, such as ‘reframing’ childhood play activities to be appropriate for adolescents. Such studies might particularly seek the perspectives of girls in the transition to adolescence.

ABSTRACT

INTRODUCTION: As problems associated with infertility and population aging increase, there is a growing interest in the factors that cause a decline in human fertility. Time-to-pregnancy (TTP) is a good indicator with which to reflect human fecundability. Here, we present a comprehensive overview of this topic.

METHODS: Relevant qualitative and quantitative studies were identified by searching the Web of science and PubMed electronic databases. We included all literature, written in English, from inception to the 10th April 2021 providing the focus was on TTP. We conducted a narrative synthesis using thematic analysis.

RESULTS: Traditional TTP-related study protocols include prospective and retrospective cohorts that provide a wealth of data to reveal potential influences on TTP. Thus far, a variety of factors have been shown to be associated with TTP in couples preparing for pregnancy, including basic demographic characteristics, menstrual status, chronic disease status, environmental endocrine disruptor exposure, and lifestyles. However, there are inevitable epidemiological bias in the existing studies, including recall bias, selection bias and measurement bias. Some methodological advances have brought new opportunities to TTP research, which make it possible to develop precision interventions for population fertility. Future TTP studies should take advantage of artificial intelligence, machine learning, and high-throughput sequencing technologies, and apply medical big data to fully consider and avoid possible bias in the design.

CONCLUSION: There are many opportunities and future challenges for TTP related studies which would provide a scientific basis for the “precise health management” of the population preparing for pregnancy.

ABSTRACT

BACKGROUND: It has been widely noted that lifetime adherence to antiretroviral therapy (ART) is necessary for HIV treatment outcome; however, retention on ART among people living with HIV (PLWH) remains a great challenge to achieve the Global AIDS Strategy: End inequalities, End AIDS. Nonadherence to ART is one of the HIV care problem in Liberia despite the availability of free ART. Psychosocial factors, i.e., perceived stigma and social support likely contributed to nonadherence to ART. We investigated associations among clinical factors, psychosocial factors, and nonadherence to ART.

METHODS: A community-based cross-sectional study was conducted among 185 PLWH, age ≥ 18 years receiving ART in Ganta, Nimba county, Liberia at least 3 months. The structured questionnaire was used to collect data from April to May 2020. Associated factors of nonadherence to ART were identified using multivariable binary logistic regression, and the p-value < 0.05 was considered statistically significant.

RESULTS: Of 185 respondents, 62.2% showed nonadherence to ART. Females reported higher nonadherence compared with males (64.4% vs. 56.6%). Multivariable binary logistic regression revealed strong experiences of stigma (PORadj = 2.392, p-value = 0.018), poor information support (PORadj = 2.102, p-value = 0.026) increased prevalence of ART nonadherence among Liberian PLWH.

CONCLUSIONS: The healthcare providers may apply interventions to reduce perceived stigma and to enhance continuous information provision in addition to support from health care providers and family members. An intensive monitoring of ART side effects is needed to be strengthened in particular among newly started ART patients.

ABSTRACT

BACKGROUND: Testicular cancer is a relatively rare form of cancer but curable. In Nigeria, late presentation hinders treatment due to limited resources for diagnosis and treatment. Testicular self-examination enables men to identify the presence of lumps and any abnormality in their testes. This can facilitate early detection and presentation at hospitals. The purpose of this study was to examine the awareness and practice of testicular self-examination by students at a College of Health Sciences in a Nigerian university.

METHODS: A cross-sectional study was conducted. The target population were second-sixth year students in the College of Health Sciences. The respondents were conveniently selected to complete a 38-item, self-administered questionnaire. The paper-based questionnaire was distributed to 280 respondents in classrooms and dormitories. Descriptive statistics (such as percentages and frequencies) were used to summarize the frequency of categorical data.

RESULTS: Of the 277 respondents, only 53.4% (n = 148) have heard about testicular self-examination. The mean age was 20.6 (± 4.51) years. Out of the 148 respondents, only 11.6% practiced it regularly. For majority of the respondents, the barriers mitigating the practice of testicular self-examination are the fear of discovering a lump and lack of knowledge.

CONCLUSION: It is necessary for the importance of testicular self-examination to be emphasized in the training of nurses, medical doctors, and other healthcare professionals and its practice should be encouraged among health science students. This will equip these students with the knowledge and skills for their health and to educate their patients and the society on the relevance of testicular self-examination.
