Workplace Violence among Nurses at a Tertiary Hospital in Myanmar: A Cross-sectional Study

WHO South East Asia J Public Health. 2023 Jul 1;12(2):93-98. doi: 10.4103/WHO-SEAJPH.WHO-SEAJPH_13_23. Epub 2024 Jan 19.

ABSTRACT

Among all types of health-care workers, nursing professionals are at the highest risk of violence since they have to deal with patients and their families directly and frequently. This study aimed to assess the magnitude of both physical and psychological workplace violence (WPV) among nurses at a public hospital in Myanmar and identify related factors. A cross-sectional study was carried out among 192 nurses with a minimum 1-year of working service at a large tertiary hospital using a standard self-administered questionnaire developed by the World Health Organization/International Labour Organization in 2003. The prevalence of overall WPV in the past 12 months was 29.2%. In particular, verbal abuse was the most frequent type (27.1%), followed by bullying/mobbing (7.8%) and physical violence (1.6%). Majority of perpetrators were patient’s relatives (62.7%) for verbal abuse and staff members (64.3%) for bullying/mobbing. The reporting rate was very low for verbal abuse (13.5%) and bullying/mobbing were not reported. Logistic regression analysis showed that respondents who were older than 45 years’ group (adjusted odds ratio [AOR]: 19.32; 95% confidence interval (CI): 1.99-186.95, P = 0.011), those who were staff nurses (AOR: 17.87; 95% CI: 1.05-33.20, P = 0.046), and those who 1-5 years and 5.1-10 years of working experiences (AOR: 18.68; 95% CI: 3.43-101.65, P = 0.001) (AOR: 15.74; 95% CI: 2.80-88.42, P = 0.002) were more likely to be exposed to WPV than their respective counterparts. Awareness generation about the importance of WPV, enforcing available legal instruments, and establishing management strategies for safe working environments should be emphasized.

Biomarker-Driven Oncology Trial Design and Subgroup Characterization: Challenges and Potential Solutions

JCO Precis Oncol. 2024 Jun;8:e2400116. doi: 10.1200/PO.24.00116.

ABSTRACT

In oncology drug development, using biomarkers to select a study population more likely to benefit from a therapeutic effect is critical to increase the efficiency of a clinical trial in demonstrating effectiveness. This perspective delves into therapeutic product approvals that were tested in pivotal trials with all-comers populations, but ultimately received US Food and Drug Administration approval for use within specific patient subgroups identified by biomarkers. Despite initial designs for efficacy and safety assessments in overall populations, a favorable benefit-risk assessment was primarily established in biomarker-positive subgroups. Analyzing these cases, we summarize key considerations pivotal to totality of evidence for regulatory benefit-risk assessments for biomarker-defined subgroup versus all-comers approvals, including biological and clinical rationales, biomarker prevalence, safety data, overall trial design, and subgroup efficacy characterization. Furthermore, a decision tree is proposed to guide optimal clinical trial design, delineating between patient enrichment and stratification, accounting for key factors including biological and clinical rationale, marker type (discreate or continuous), prevalence, assay readiness, and turnaround times for marker assessment. Finally, a recommended approach for subgroup characterization involves prespecifying magnitude of improvement that would be considered clinically meaningful in the biomarker-negative subgroup, which can be supplemented with methodologies such as Bayesian to incorporate evidence from similar studies when available. In summary, this perspective underscores the importance of clinical trial innovations, statistical methodologies and regulatory considerations, to optimize biomarker-driven drug development for patients with cancer.

Shared Genetic Architecture Between Schizophrenia and Anorexia Nervosa: A Cross-trait Genome-Wide Analysis

Schizophr Bull. 2024 Jun 7:sbae087. doi: 10.1093/schbul/sbae087. Online ahead of print.

ABSTRACT

BACKGROUND AND HYPOTHESIS: Schizophrenia (SCZ) and anorexia nervosa (AN) are 2 severe and highly heterogeneous disorders showing substantial familial co-aggregation. Genetic factors play a significant role in both disorders, but the shared genetic etiology between them is yet to be investigated.

STUDY DESIGN: Using summary statistics from recent large genome-wide association studies on SCZ (Ncases = 53 386) and AN (Ncases = 16 992), a 2-sample Mendelian randomization analysis was conducted to explore the causal relationship between SCZ and AN. MiXeR was employed to quantify their polygenic overlap. A conditional/conjunctional false discovery rate (condFDR/conjFDR) framework was adopted to identify loci jointly associated with both disorders. Functional annotation and enrichment analyses were performed on the shared loci.

STUDY RESULTS: We observed a cross-trait genetic enrichment, a suggestive bidirectional causal relationship, and a considerable polygenic overlap (Dice coefficient = 62.2%) between SCZ and AN. The proportion of variants with concordant effect directions among all shared variants was 69.9%. Leveraging overlapping genetic associations, we identified 6 novel loci for AN and 33 novel loci for SCZ at condFDR <0.01. At conjFDR <0.05, we identified 10 loci jointly associated with both disorders, implicating multiple genes highly expressed in the cerebellum and pituitary and involved in synapse organization. Particularly, high expression of the shared genes was observed in the hippocampus in adolescence and orbitofrontal cortex during infancy.

CONCLUSIONS: This study provides novel insights into the relationship between SCZ and AN by revealing a shared genetic component and offers a window into their complex etiology.

Association Between Time to Treatment With Endovascular Thrombectomy and Home-Time After Acute Ischemic Stroke

Neurology. 2024 Jun 25;102(12):e209454. doi: 10.1212/WNL.0000000000209454. Epub 2024 Jun 7.

ABSTRACT

BACKGROUND AND OBJECTIVES: Home-time is a patient-prioritized stroke outcome that can be derived from administrative data linkages. The effect of faster time-to-treatment with endovascular thrombectomy (EVT) on home-time after acute stroke is unknown.

METHODS: We used the Quality Improvement and Clinical Research registry to identify a cohort of patients who received EVT for acute ischemic stroke between 2015 and 2022 in Alberta, Canada. We calculated days at home in the first 90 days after stroke. We used ordinal regression across 6 ordered categories of home-time to evaluate the association between onset-to-arterial puncture and higher home-time, adjusting for age, sex, rural residence, NIH Stroke Scale, comorbidities, intravenous thrombolysis, and year of treatment. We used restricted cubic splines to assess the nonlinear relationship between continuous variation in time metrics and higher home-time, and also reported the adjusted odds ratios within time categories. We additionally evaluated door-to-puncture and reperfusion times. Finally, we analyzed home-time with zero-inflated models to determine the minutes of earlier treatment required to gain 1 day of home-time.

RESULTS: We had 1,885 individuals in our final analytic sample. There was a nonlinear increase in home-time with faster treatment when EVT was within 4 hours of stroke onset or 2 hours of hospital arrival. There was a higher odds of achieving more days at home when onset-to-puncture time was <2 hours (adjusted odds ratio 2.36, 95% CI 1.77-3.16) and 2 to <4 hours (1.37, 95% CI 1.11-1.71) compared with ≥6 hours, and when door-to-puncture time was <1 hour (aOR 2.25, 95% CI 1.74-2.90), 1 to <1.5 hours (aOR 1.89, 95% CI 1.47-2.41), and 1.5 to <2 hours (1.35, 95% CI 1.04-1.76) compared with ≥2 hours. Results were consistent for reperfusion times. For every hour of faster treatment within 6 hours of stroke onset, there was an estimated increase in home-time of 4.7 days, meaning that approximately 1 day of home-time was gained for each 12.8 minutes of faster treatment.

DISCUSSION: Faster time-to-treatment with EVT for acute stroke was associated with greater home-time, particularly within 4 hours of onset-to-puncture and 2 hours of door-to-puncture time. Within 6 hours of stroke onset, each 13 minutes of faster treatment is associated with a gain of 1 day of home-time.

Investigation on the Effectiveness of Digital Scanning Combined with Reverse Engineering Technology in Demonstrating Full Crown Tooth Preparation

Int J Prosthodont. 2024 Jun 7;0(0):1-22. doi: 10.11607/ijp.8968. Online ahead of print.

ABSTRACT

OBJECTIVE: To investigate the effect of digital scanning combined with reverse engineering technology in the demonstration of full crown tooth preparation.

METHODS: Thirty-one students were randomly divided into the two groups. The students in the control group carried out traditional demonstration by the use of eye-measurement methods. The students in the experimental group carried out improved demonstration by the use of digital intraoral scan with 3D measurement data. The students in both groups were provided with two resin teeth to conduct full crown tooth preparation on head model dental simulators. The teeth prepared before and after demonstration were scored by Chinese Stomatological Association Group Standards, with a total score of 100 points. Analysis of covariance was performed to comparatively analyze the scores related to the tooth surfaces, and convergence angle between two groups.

RESULTS: Analysis of two prepared teeth (tooth #11 and #16) in two groups showed that there was a statistical significant difference in the mean score between the control group and experimental group (tooth #11, P = 0.0039) (tooth #16, P = 0.0120).The demonstration of the tooth #16 showed that there were statistical significant differences in the scores related to buccolingual surface (P = 0.0205) and proximal surface (P = 0.0023) between the control group and experimental group; There was a statistical significant difference in the score related to the convergence angle of buccolingual surface between the control group and experimental group (P = 0.0265).

CONCLUSION: The digital methods can effectively improve the quality of tooth preparations and has a pedagogical advantage for posterior teeth, which present greater operational challenges.

Therapeutic hypothermia: A descriptive, cohort study conducted over 10 years at a tertiary care public hospital

Arch Argent Pediatr. 2024 Jun 13:e202310264. doi: 10.5546/aap.2023-10264.eng. Online ahead of print.

ABSTRACT

Introduction. Therapeutic hypothermia (TH) reduces the risk of death or disability in children with moderate to severe hypoxic ischemic encephalopathy (HIE). Objective. To describe a population of patients with HIE that required TH and their course until discharge. Population and methods. Retrospective, descriptive, cohort study. All patients admitted to TH between 2013 and 2022 were studied. Epidemiological, clinical, monitoring, and treatment data were assessed, together with supplementary tests and condition at discharge. Risk factors were compared between deceased patients and survivors; and, among the latter, those requiring special healthcare needs (SHCN) at discharge. Results. A total of 247 patients were included. Mortality: 11%. Most common sentinel event: prolonged second stage of labor (39%). Treatment initiation: median of 5 hours of life. Seizures: 57%. Intravenous erythropoietin: 66.7%. Abnormal pattern in brain function monitoring: 52%. Normalization of monitoring: median of 24 hours. Pathological magnetic resonance imaging: 42%. Predictor variables of mortality: severe Sarnat and Sarnat staging and pathological ultrasound upon admission. Conclusion. The overall mortality rate was 11%. Referrals increased more markedly since 2018. The time of TH initiation was later than in previous reports. Severe neurological signs as per the Sarnat and Sarnat staging and a pathological baseline cranial ultrasound were independent predictors of mortality at discharge. Patients with SHCN at discharge showed a normalized tracing in the amplitude-integrated electroencephalography performed later. The most common finding in the magnetic resonance imaging was basal ganglia involvement. No statistically significant differences were observed in terms of clinical characteristics or complications among patients who received erythropoietin.

Examiner workload comparison: three structured oral examination formats for the European diploma in anaesthesiology and intensive care

Med Educ Online. 2024 Dec 31;29(1):2364990. doi: 10.1080/10872981.2024.2364990. Epub 2024 Jun 7.

ABSTRACT

The COVID-19 pandemic triggered transformations in academic medicine, rapidly adopting remote teaching and online assessments. Whilst virtual environments show promise in evaluating medical knowledge, their impact on examiner workload is unclear. This study explores examiner’s workload during different European Diploma in Anaesthesiology and Intensive Care Part 2 Structured Oral Examinations formats. We hypothesise that online exams result in lower examiner’s workload than traditional face-to-face methods. We also investigate workload structure and its correlation with examiner characteristics and marking performance. In 2023, examiner’s workload for three examination formats (face-to-face, hybrid, online) using the NASA TLX instrument was prospectively evaluated. The impact of examiner demographics, candidate scoring agreement, and examination scores on workload was analysed. The overall NASA TLX score from 215 workload measurements in 142 examiners was high at 59.61 ± 14.13. The online examination had a statistically higher workload (61.65 ± 12.84) than hybrid but not face-to-face. Primary contributors to workload were mental and temporal demands, and effort. Online exams were associated with elevated frustration. Male examiners and those spending more time on exam preparation experienced a higher workload. Multiple diploma specialties and familiarity with European Diploma in Anaesthesiology and Intensive Care exams were protective against high workload. Perceived workload did not impact marking agreement or examination scores across all formats. Examiners experience high workload. Online exams are not systematically associated with decreased workload, likely due to frustration. Despite workload differences, no impact on examiner’s performance or examination scores was found. The hybrid examination mode, combining face-to-face and online, was associated with a minor but statistically significant workload reduction. This hybrid approach may offer a more balanced and efficient examination process while maintaining integrity, cost savings, and increased accessibility for candidates.

Nirmatrelvir-Ritonavir and Symptoms in Adults With Postacute Sequelae of SARS-CoV-2 Infection: The STOP-PASC Randomized Clinical Trial

JAMA Intern Med. 2024 Jun 7. doi: 10.1001/jamainternmed.2024.2007. Online ahead of print.

ABSTRACT

IMPORTANCE: There is an urgent need to identify treatments for postacute sequelae of SARS-CoV-2 infection (PASC).

OBJECTIVE: To assess the efficacy of a 15-day course of nirmatrelvir-ritonavir in reducing the severity of select PASC symptoms.

DESIGN, SETTING, AND PARTICIPANTS: This was a 15-week blinded, placebo-controlled, randomized clinical trial conducted from November 2022 to September 2023 at Stanford University (California). The participants were adults with moderate to severe PASC symptoms of 3 months or longer duration.

INTERVENTIONS: Participants were randomized 2:1 to treatment with oral nirmatrelvir-ritonavir (NMV/r, 300 mg and 100 mg) or with placebo-ritonavir (PBO/r) twice daily for 15 days.

MAIN OUTCOMES AND MEASURES: Primary outcome was a pooled severity of 6 PASC symptoms (fatigue, brain fog, shortness of breath, body aches, gastrointestinal symptoms, and cardiovascular symptoms) based on a Likert scale score at 10 weeks. Secondary outcomes included symptom severity at different time points, symptom burden and relief, patient global measures, Patient-Reported Outcomes Measurement Information System (PROMIS) measures, orthostatic vital signs, and sit-to-stand test change from baseline.

RESULTS: Of the 155 participants (median [IQR] age, 43 [34-54] years; 92 [59%] females), 102 were randomized to the NMV/r group and 53 to the PBO/r group. Nearly all participants (n = 153) had received the primary series for COVID-19 vaccination. Mean (SD) time between index SARS-CoV-2 infection and randomization was 17.5 (9.1) months. There was no statistically significant difference in the model-derived severity outcome pooled across the 6 core symptoms at 10 weeks between the NMV/r and PBO/r groups. No statistically significant between-group differences were found at 10 weeks in the Patient Global Impression of Severity or Patient Global Impression of Change scores, summative symptom scores, and change from baseline to 10 weeks in PROMIS fatigue, dyspnea, cognitive function, and physical function measures. Adverse event rates were similar in NMV/r and PBO/r groups and mostly of low grade.

CONCLUSIONS AND RELEVANCE: The results of this randomized clinical trial showed that a 15-day course of NMV/r in a population of patients with PASC was generally safe but did not demonstrate a significant benefit for improving select PASC symptoms in a mostly vaccinated cohort with protracted symptom duration. Further studies are needed to determine the role of antivirals in the treatment of PASC.

A study on the influencing factors of rural land transfer willingness in different terrain areas–Based on the questionnaire survey data of Anhui Province and Qinghai Province, China

PLoS One. 2024 Jun 7;19(6):e0303078. doi: 10.1371/journal.pone.0303078. eCollection 2024.

ABSTRACT

This study delves into the factors influencing the willingness of rural land transfers in different terrain areas, aiming to promote the improvement of land transfer institutions and accelerate the process of scale farming. Based on rural survey data from Anhui and Qinghai provinces in China, this research uses geographical detector and Binary Logistic Model to explore the differential factors affecting the willingness of farmers to participate in land contract transfer in the first and third terrain areas of China. The study examines four dimensions, including individual characteristics, family endowments, social support strategies, and geographical environment. The findings reveal the following: (1) By comparing the mean values, standard deviations, and coefficients of variation of the data from both provinces, it is evident that the indicators of individual characteristics, family endowments, social support strategies, and geographical environment differ significantly between the two provinces. This indicates substantial disparities in the basic attributes of farmers and their living environments. (2) The single-factor explanatory power significantly influencing farmers’ willingness to engage in land transfer varies considerably and is statistically significant at the 1% level. The types of interaction between two factors mainly include dual-factor enhancement, nonlinear enhancement, single-factor nonlinear attenuation, and nonlinear attenuation. (3) There are commonalities and differences in the factors that significantly influence farmers’ willingness to participate in land transfer in the two provinces. Common factors influencing farmers’ land transfer willingness in both provinces include: the educational level of household heads, the health status of household heads, the number of family laborers, the arable land area, the differentiation of agricultural management objectives, the proportion of agricultural operating income, labor service economy, and relocation policies. Factors showing different influences include: the age of household heads, school-age children, the number of family members engaged in different occupations, the proportion of income from off-farm employment, minimum guarantee policies credit support, location distance, and terrain undulation. Therefore, in formulating land transfer policies, the government should prioritize significant driving factors influencing farmers’ decision-making behavior in different regions. It is essential to develop and implement land transfer policies tailored to local conditions with the primary goal of safeguarding the rights and interests of the principal stakeholders, thus achieving sustainable land utilization.

A meta-analysis of the association between inflammatory cytokine polymorphism and neonatal sepsis

PLoS One. 2024 Jun 7;19(6):e0301859. doi: 10.1371/journal.pone.0301859. eCollection 2024.

ABSTRACT

OBJECTIVE: The purpose of this study is to investigate the relationship between single nucleotide polymorphisms of inflammatory cytokines and neonatal sepsis through meta-analysis.

METHODS: We collected research literature on the correlation between inflammatory cytokine polymorphisms and neonatal sepsis published before August 2023 through computer searches of databases such as PubMed, Embase, etc. The Stata 14.0 software was utilized for Meta-analysis. To assess heterogeneity, the chi-squared Q-test and I2 statistics were used. The Egger and Begg tests were conducted to determine the possibility of publication bias.

RESULTS: After reviewing 1129 articles, 29 relevant articles involving 3348 cases and 5183 controls were included in the study. The meta-analysis conducted on IL-1βrs1143643 polymorphism revealed significant findings: the T allele genotype has a lower risk of neonatal sepsis(P = 0.000, OR = 0.224, 95% CI: 0.168-0.299), while the TC and TT genotypes showed an increased risk(TC: P = 0.000,OR = 4.251, 95% CI: 2.226-8.119; TT: P = 0.019,OR = 2.020, 95% CI: 1.122-3.639). Similarly, newborns with the IL-6-174 CC genotype had a significantly higher risk of sepsis(P = 0.000,OR = 1.591, 95% CI: 1.154-2.194), while those with the IL-8-rs4073 TT (P = 0.003,OR = 0.467, 95% CI: 0.280-0.777)and TT + AA(P = 0.003,OR = 0.497, 95% CI: 0.315-0.785) genotypes had a significantly lower risk of sepsis. For the IL-10-1082 gene, newborns with the AA genotype(P = 0.002,OR = 1.702, 95% CI: 1.218-2.377), as well as those with the AA + GA genotype(P = 0.016,OR = 1.731, 95% CI: 1.108-2.705), had a significantly higher risk of sepsis. Lastly, newborns carrying the TNF-α-308 A allele (P = 0.016,OR = 1.257, 95% CI: 1.044-1.513)or the AA genotype(P = 0.009,OR = 1.913, 95% CI: 1.179-3.10) have a significantly increased risk of sepsis. Notwithstanding, additional studies must be included for validation. Applying these cytokines in clinical practice and integrating them into auxiliary examinations facilitates the early detection of susceptible populations for neonatal sepsis, thereby providing a new diagnostic and therapeutic approach for neonatal sepsis.
