Mind the gap: Gender disparities in authorship in the Journal of Medical Imaging and Radiation Sciences.

INTRODUCTION: Research studies tracking gender and academic publication productivity in healthcare find gender disparities in research activity, publication, and authorship. Article authorship is one of the important metrics to track when seeking to understand gender inequality in academic career advancement. Research on gender disparities in publication productivity in the field of Medical Radiation Science (MRS) is very limited thus this study analyses and explains potential gender differences in article authorship and acceptance for publication in the Journal of Medical Imaging and Radiation Sciences (JMIRS) for a 5-year period (2017-2021). METHODS: Gender was inferred based on the author's first name or title (e.g., Mr, Mrs or Ms). For those who left the title blank or reported as 'Dr' or 'Prof,' a series of steps were taken to identify their gender. Where gender was impossible to ascribe, these authors were excluded. Descriptive and inferential statistics are reported for the study population. Descriptive and inferential statistics are used. Percentages of females are reported, and males constitute the other portion. Chi-square, slope analysis and z-tests were used to test hypotheses. RESULTS: Results show that female authorship overall and in all categories of authorship placement (i.e., first, last and corresponding) increased over the timeframe reviewed. The percentage gain in the increase was higher than that for male authorship. However, male authorship started from a higher baseline in 2017 and has also increased year on year and overall, as well as in each placement category examined. More female authors were in the MRS sub-specialism Radiation Therapy (RT) than in the other MRS sub-specialisms. Analysis of the acceptance rate of articles with female authors shows a weak downward trend, and this may be related to higher submission and acceptance rates of articles by male authors during the same period. CONCLUSION: Male authors are overrepresented in all categories, which raises questions about the persistence of gender disparities in JMIRS authorship and article acceptance. Positive trends in female authorship indicate progress, yet there is the persistence of the significant under-representation of women in the Medical Radiation Sciences workforce in academic publishing. Recruiting more males to address the gender imbalance in the profession should not be at the expense of females' career progression.

Poverty trajectories and child and mother well-being outcomes in Ireland: findings from an Irish prospective cohort.

BACKGROUND: Poverty is associated with poor outcomes, yet exposure to distinct poverty trajectories in early childhood is not well understood. OBJECTIVE: To understand the prevalence of different trajectories of household poverty and their association with mid-childhood and mother indicators of physical health and psychopathology in Ireland. METHODS: We used a nationally representative, prospective cohort (Growing Up in Ireland-Infant Cohort). Household poverty included lowest third income decile, subjective poverty and material deprivation when children were aged 9 months, and 3, 5, 9 years. We used group-based multitrajectory cluster modelling to classify trajectories of poverty. Using multivariable logistic regression, adjusted with separate child and mother confounders, we assessed the association of poverty trajectories from 9 months to 9 years with child outcomes (overweight, any longstanding illness and psychopathology) at age 9 years and the same poverty trajectories over the same 9-year period with mother outcomes (overweight, any longstanding illness and depression). RESULTS: Of 11 134 participants, 4 trajectories were identified: never in poverty (43.1%), material/subjective>monetary poverty (16.1%), monetary>material poverty (25.6%) and persistent poverty (15.2%). Children in persistent poverty compared with those in never in poverty experienced higher odds of being overweight at 9 years (adjusted OR (aOR) 1.70, 95% CI 1.34, 2.16), having a longstanding illness (aOR 1.51, 95% CI 1.20, 1.91), and psychopathology (aOR 2.06, 95% CI 1.42, 2.99). The outcomes for primary parents (99.7% were mothers) were as follows: having higher odds of being overweight (aOR 1.49, 95% CI 1.16, 1.92), having a longstanding illness (aOR 2.13, 95% CI 1.63, 2.79), and depression (aOR 3.54, 95% CI 2.54, 4.94). CONCLUSIONS: Any poverty trajectory was associated with poorer psychopathology and physical well-being in late childhood for children and their mothers in Ireland.

Household energy poverty and trajectories of emotional and behavioural difficulties in children and adolescents: findings from two prospective cohort studies.

PURPOSE: The aim of this study is to examine the association between household energy poverty (EP) and trajectories of emotional and behavioural difficulties during childhood. METHODS: The Growing up in Ireland study is two nationally representative prospective cohorts of children. The Infant Cohort (n = 11,134) were recruited at age 9 months (9 m) and followed up at 3, 5, 7 and 9 years (y). The Child Cohort (n = 8,538) were recruited at age 9 y and followed up at 13 y and 17/18 y. EP was a composite of two relative measures of EP. Emotional and behavioural difficulties were repeatedly measured using the strengths and difficulties questionnaire (SDQ). Linear spline multilevel models were used, adjusted for confounders to examine the association between (1) EP (9 m or 3 y) and trajectories of emotional and behavioural difficulties from 3 to 9 y in the Infant Cohort and (2) EP at 9 y and the same trajectories from 9 to 18 y in the Child Cohort. RESULTS: In adjusted analyses, EP at 9 m or 3 y of age was associated with higher total difficulties score at 3 y (0.66, 95% CI 0.41, 0.91) and 5 y (0.77, 95% CI 0.48, 1.05) but not at 7 y or 9 y. EP at 9 y was associated with higher total difficulties score at 9 y (1.73, 95% CI 1.28, 2.18), with this difference reducing over time leading to 0.68 (95% CI 0.19, 1.17) at 17/18 y. CONCLUSIONS: Our study demonstrates a potential association between early life EP and emotional and behavioural difficulties that may be transient and attenuate over time during childhood. Further studies are required to replicate these findings and to better understand if these associations are causal.

Fentanyl, Acetylfentanyl and Carfentanil in Impaired Driving Cases: A Review of 270 Cases.

The detection of fentanyl (FEN) and FEN analogs has been widely communicated throughout the scientific community. While most of the reporting has been in relation to overdose deaths, these drugs are commonly detected in impaired driving cases. A retrospective study of impaired driving cases analyzed between 2017 and 2019 produced 270 cases positive for FEN, carfentanil (CFEN) and/or acetylfentanyl (AFEN). FEN was the predominant drug found in these 270 cases (65.5%) with concentrations ranging from less than 1.0 to 64 ng/mL. CFEN was found alone in 6.6% cases with three concentrations above 1.0 ng/mL. AFEN was always found when FEN was positive with concentrations ranging from <1.0 to 9.2 ng/mL. Detailed case histories are provided with corresponding toxicology results. Toxicology results show impaired drivers using multiple drugs with a wide range of observed behaviors. The inclusion of these drugs in routine impaired driver toxicology testing is extremely important when attempting to determine their overall prevalence.

A systematic review protocol of quantitative instruments of income inequality in studies of children and adolescents.

Background: Income inequality is an important indicator of socioeconomic position which is a determinant of social, psychological, and physical health outcomes from childhood to adulthood. Different income inequality instruments (metrics) are used to investigate associations between income inequality and health outcomes (e.g. Gini coefficient). Income inequality instruments provide unique information on the construct of socioeconomic inequality. Albeit there is variation in studies as to the type and rationale for using a particular quantitative instrument of income inequality. The aim of this systematic review will be to investigate and identify the most used quantitative income inequality instrument in studies of children and adolescents up to 18 years of age.   Methods: The PRISMA-P framework will be applied to identify high quality articles (PROSPERO: CRD42021259114). A search will be conducted in PubMed, Embase, and PsycINFO. The search will include studies concerned with income inequality and/or socioeconomic inequality in children and adolescents. All articles will be independently reviewed, data extracted, and quality appraised by two reviewers and a third to arbitrate disputes. Articles will be reviewed by title and abstract using inclusion criteria. A data extraction form will be used. Three questions will assess the quality of the rationale for using a particular income inequality instrument and the Newcastle-Ottawa Scale will be used to assess bias and quality. The primary outcome of interest is the type and frequency of quantitative income inequality instruments used and the study outcome associated with that income inequality instrument.  Conclusions: This systematic review will aim to provide a summary of the different types of quantitative income inequality instruments used in studies of child and adolescent populations. This will help to guide researchers and policy makers on the use of income inequality metrics in future studies aimed at understanding associations with health and social outcomes in children and adolescents.

Mental health following an initial period of COVID-19 restrictions: findings from a cross-sectional survey in the Republic of Ireland.

Background: We assessed the mental health of individuals in the general population, during an initial period of easing of COVID-19 restrictions in the Republic of Ireland (RoI). Methods: Data were collected through a nationally representative cross-sectional telephone survey, during the first period of easing of restrictions during the COVID-19 pandemic between May and July 2020. Mental health was examined using the Patient Health Questionnaire Anxiety Depression Scale. Poisson regression analyses were conducted to estimate risk ratios with robust variance estimation of the association between selected demographic factors and the risk of having depression and anxiety symptoms. Results: Of the 1,983 participants, 27.7% (n = 549; 95% CI: 0.26 - 0.30) reported depression and anxiety symptoms, while 74 (3.8%; 95% CI: 0.03 - 0.05) disclosed self-harm and/or suicidal thoughts. Females (RR: 1.60, 95% CI: 1.37 - 1.87, p < 0.0005), employed individuals who experienced a change in work status (RR: 1.50, 95% CI: 1.24 - 1.82, p < 0.0005), participants cocooning due to a health condition (RR: 1.34, 95% CI: 1.08 - 1.66, p< 0.01), participants who were self-isolating (RR: 1.25, 95% CI: 1.03 - 1.51, p=0.025) and moderate-heavy drinkers (RR: 1.27, 95% CI: 1.09 - 1.47, p<0.01) were at increased risk of depression and anxiety. Young people aged 18-29 years and those in the two lowest income categories were most likely to report self-harm and/or suicidal thoughts. Conclusion: As the COVID-19 pandemic continues, with further waves and associated restrictions, the impact on mental health in the population as a whole and in specific subgroups must be considered.

Covid-19 Estimating the burden of symptomatic disease in the community and the impact of public health measures on physical, mental and social wellbeing: a study protocol.

Introduction: Covid-19 was declared a pandemic in March 2020. Since then, governments have implemented unprecedented public health measures to contain the virus. This study will provide evidence to inform responses to the pandemic by: i) estimating population prevalence and trends of self-reported symptoms of Covid-19 and the proportions of symptomatic individuals and household contacts testing positive for Covid-19; ii) describing acceptance and compliance with physical-distancing measures, explore effects of public health measures on physical, mental and social wellbeing; iii) developing a mathematical network model to inform decisions on the optimal levels of physical distancing measures. Methods: Two cross-sectional nationally-representative telephone surveys will be conducted in Ireland using random digit-dialling, with response rates estimates based on proportion of non-operational and non-answering numbers. The first survey with four waves in May and June will address adherence to social distancing measures and whether the respondent or other household members are or have been unwell during the preceding two weeks with one or more symptoms of Covid-19. The second survey with three waves in June, July and September will address knowledge, attitudes, and compliance towards physical-distancing measures and physical, mental and social wellbeing. The mathematical network model will be developed for all-Ireland (on various levels of spatial granularity including the scale of counties and electoral divisions) based on outputs from both cross-sectional surveys and relevant publicly available data to inform decisions on optimal levels and duration of physical distancing measures. Discussion: This study will contribute to our understanding of the impact and sustainability of public health measures of the Covid-19 pandemic. Findings will have long-lasting benefits, informing decision-making on the best levels, and duration of physical-distancing measures, balancing a range of factors including capacity of the health service with the effects on individuals' wellbeing and economic disruption. Findings will be shared with key policy-makers.

Routine clinical testing underestimates proprioceptive deficits in Friedreich's ataxia.

Friedreich's ataxia (FA) is the most common recessive ataxia in the Western world with degeneration of dorsal root ganglia neurons as its major neuropathological hallmark. The sensitivity of clinical tools commonly used for the assessment of the proprioceptive component of FA is currently unknown. We hypothesised that current clinical testing underestimates proprioceptive deficits in FA patients. Such an underestimation would hamper our understanding of the components of FA, the monitoring of disease progression, and the detection of deficits in the current advent of drug trials. We compared clinical tests for joint position sense (JPS) and vibration sense (VS) to a test of spatial position sense (SPS) that examines localisation of both hands across a horizontal 2D space. We tested 22 healthy controls to derive a cut-off for the SPS. Eleven patients with genetically confirmed FA participated in this study. All 11 FA patients were impaired in the SPS test. Two patients showed unimpaired JPS and VS. Two additional patients showed unimpaired JPS, while two other patients unimpaired VS. The SPS test was more sensitive and revealed deficits potentially earlier than clinical screening tests. Only the SPS showed a positive correlation with ataxia severity. The SPS was more sensitive than the commonly used JPS and VS. Thus, our results indicate that proprioceptive deficits in FA start earlier and are more severe than indicated by routine standard clinical testing. The contribution of proprioceptive deficits to the impairment of FA patients might therefore indeed be underestimated today.

Quantitation of first- and second-generation antipsychotics by LC-MS/MS.

Antipsychotic drugs are becoming a larger part of the prescription drug market. In combination with -traditional indications for prescribing these drugs, new effective therapies are proving worthwhile as well. Here, a successful method for detecting both first- and second-generation antipsychotics is presented using a solid phase extraction method and LC-MS/MS detection. This method is used for many sample matrices and can also be used for detecting antidepressants, which are often prescribed in conjunction with antipsychotics.

A fatality from an oral ingestion of methamphetamine.

The case presented is of a 49-year-old white male decedent who admitted to oral ingestion of methamphetamine. He believed he was being followed by the police while walking his daughter to school in the morning and swallowed the "8-ball of meth," which is known to be one-eighth of an ounce or the equivalent of about 3 g. The following autopsy specimens were analyzed for the presence of methamphetamine and amphetamine by gas chromatography-mass spectrometry: femoral blood, urine, bile, vitreous fluid, brain, liver, and gastric contents. Blood drawn at the hospital approximately 12 h after ingestion was also analyzed. The methamphetamine concentration in the hospital blood was 3.0 mg/L, and the concentration in the femoral blood from autopsy was 30 mg/L. Other drugs confirmed included tramadol, lorazepam, and 11-carboxy-Delta(9)-tetrahydrocannabinol. The pathologist ruled the cause of death to be cardiac dysrhythmia due to excited delirium as a result of methamphetamine drug effects. Discussion of the timeline from ingestion to death and the clinical presentation of the decedent are included.

Vitreous fluid quantification of opiates, cocaine, and benzoylecgonine: comparison of calibration curves in both blood and vitreous matrices with corresponding concentrations in blood.

Vitreous fluid specimens are often used in the Montgomery County Coroner's Office as a second matrix confirmation for both cocaine and opiate analyses. In this manuscript, calibration curves constructed for both vitreous and blood were used to quantify vitreous specimens to evaluate if any matrix effects occur when measuring vitreous specimens using a calibration curve in blood. Cases that screened positive by ELISA for cocaine metabolite and opiates were confirmed by solid-phase extraction. Gas chromatography with mass spectral detection in the positive electron impact mode was used for the detection and quantification of oxycodone, free morphine, codeine, 6-monoacetylmorphine, hydrocodone, cocaine, and benzoylecgonine. For interpretive purposes, no significant matrix effects were found in concentrations of vitreous specimens quantified with a calibration curve constructed in a blood matrix. After determining that vitreous fluid can be accurately measured with blood calibrators, a comparison was made between blood and vitreous concentrations for the above analytes. Concentration differences between blood and vitreous specimens for each drug are evaluated with selected case histories included.
