Scar on my heart: effects of unemployment experiences on coronary heart disease

Purpose The purpose of this paper is to study the impact of unemployment on coronary heart diseases (CHD) in Italy on a sample of male manual workers in the private sector. Design/methodology/approach The authors investigate the association between CHD and different unemployment experiences (ever unemployed; short, mid and long cumulative unemployment), exploiting a large Italian administrative database on careers and health. The study design is based on the balancing of individuals' characteristics during a 12-year pre-treatment period; the measurement of unemployment occurrence during a seven-year treatment period; the observation of CHD occurrence during a five-year follow up. The workers characteristics and the probability of receiving the treatment are balanced by means of propensity score matching. Standard diagnostics on the balancing assumption are discussed and satisfied, while the robustness to violations of the unconfoundedness assumption is evaluated by a simulation-based sensitivity analysis. Findings The authors find a significant increase of CHD probability was found among workers who experience more than three years of unemployment (relative risks (RR)=1.91, p&lt;0.1), and among those who exit unemployment starting a self-employment activity (RR=1.70, p&lt;0.1). Using different selections of the study population, a clear pattern emerges: the healthier and more labour market attached are workers during pre-treatment, the greater is the negative impact of long-term unemployment on health (RR=2.79, p&lt;0.01). Originality/value The very large representative sample (n=69,937) and the deep longitudinal dimension of the data (1985-2008) allowed the authors to minimize the risks of health selection and unemployment misclassification. Moreover, the adopted definition of unemployment corrected some undercoverage and misclassification issues that affect studies based on a purely administrative definition and that treat unemployment as a unique career event disregarding the duration of the experience. </jats:sec

Is empowerment of female radiologists still needed? Findings of a systematic review

Considering that radiology is still a male-dominated specialty in which men make up more than two thirds of the workforce, this systematic review aimed to provide a comprehensive overview of the current role of women in radiological imaging, focusing on the main aspects such as career progression, leadership, academic practice, and perceived discrimination. Three electronic databases were searched up to 21 October 2020. To identify additional records, weekly automatic email alerts were set up on PubMed until December 2020 and reference lists of key studies and included papers were screened. Two reviewers independently performed the search, study selection, quality appraisal, data extraction, and formal narrative synthesis. In case of disagreement, a third reviewer was involved. Across the 61 included articles, women worked more often part-time and held fewer positions of power in hospitals, on editorial boards, and at the academic level (associate and full professors). Women were less often in relevant positions in scientific articles, had fewer publications, and had a lower H-index. Discrimination and sexual harassment were experienced by up to 40% and 47% of female radiologists, respectively. Our study highlights that women in radiology are still underrepresented and play a marginal role in the field, struggling to reach top and leading positions

Monitoring Chemical Changes of Coffee Beans During Roasting Using Real-time NIR Spectroscopy and Chemometrics

Variations occurring in coffee beans during roasting are ascribable to several chemical-physical phenomena: to quickly track the whole process and to ensure its reproducibility, a process analytical technology (PAT) approach is needed. In this study, a method combining in-line Fourier transform near-infrared (FT-NIR) spectroscopy and chemometric modelling was investigated to get real-time and practical knowledge about the roasting effects on coffee’s chemical-physical composition. In-line spectra were acquired by inserting a NIR probe into a laboratory coffee roaster, running twenty-four roasting experiments, planned spanning different coffee species (Arabica and Robusta), four roasting temperature settings (TS1–TS4) and times (650–1580 s). Multivariate curve resolution-alternate least squares (MCR-ALS) was used to model the chemical-physical changes occurring during the roasting process, and information about maximum rate, acceleration and deceleration of the process was obtained, also highlighting potential effects due to the different roasting temperatures and coffee varieties. The proposed approach provides the groundwork for direct real-time implementation of rapid, non-invasive automated monitoring of the roasting process at industrial scale

Normalized STEAM-based diffusion tensor imaging provides a robust assessment of muscle tears in football players: preliminary results of a new approach to evaluate muscle injuries

Objectives: To assess acute muscle tears in professional football players by diffusion tensor imaging (DTI) and evaluate the impact of normalization of data. Methods: Eight football players with acute lower limb muscle tears were examined. DTI metrics of the injured muscle and corresponding healthy contralateral muscle and of ROIs drawn in muscle tears (ROItear) in the corresponding healthy contralateral muscle (ROIhc_t) in a healthy area ipsilateral to the injury (ROIhi) and in a corresponding contralateral area (ROIhc_i) were compared. The same comparison was performed for ratios of the injured (ROItear/ROIhi) and contralateral sides (ROIhc_t/ROIhc_i). ANOVA, Bonferroni corrected post-hoc and Students t-tests were used. Results: Analyses of the entire muscle did not show any differences (p>0.05 each) except for axial diffusivity (AD; p=0.048). ROItear showed higher mean diffusivity (MD) and AD than ROIhc_t (p<0.05). Fractional anisotropy (FA) was lower in ROItear than in ROIhi and ROIhc_t (p<0.05). Radial diffusivity (RD) was higher in ROItear than in any other ROI (p<0.05). Ratios revealed higher MD and RD and lower FA and reduced number and length of fibre tracts on the injured side (p<0.05 each). Conclusions: DTI allowed a robust assessment of muscle tears in athletes especially after normalization to healthy muscle tissue. Key Points STEAM-based DTI allows the investigation of muscle tears affecting professional football players. Fractional anisotropy and mean diffusivity differ between injured and healthy muscle areas. Only normalized data show differences of fibre tracking metrics in muscle tears. The normalization of DTI-metrics enables a more robust characterization of muscle tears.(VLID)475075

Gender-specific Anatomical Distribution of Internal Pudendal Artery Perforator: A Radiographic Study for Perineal Reconstruction

Background: Cancer, trauma, infection, or radiation can cause perineal defects. Fasciocutaneous flaps based on perforator vessels (PV) from the internal pudendal artery (IPA) provide an ideal reconstructive option for moderate defects. We hypothesized that, due to gender differences in the pelvic-perineal region, the anatomical distribution of PV differs between genders. Methods: Computed tomography angiographies from male and female patients without pelvic-perineal pathologies were retrospectively analyzed to study the vascular anatomy of the IPA. The number, size, type, and distribution of PV were recorded and compared between genders. Four anatomical regions were defined to describe the distribution of PV on each perineal side: anterior (A), anterior-central (AC), central-posterior (CP), and posterior (P). Results: A total of 63 computed tomography angiographies were analyzed (men, 31; women, 32). Each IPA provides 2 +/- 1 PV and 5 +/- 2 terminal (cutaneous) branches: in both genders, 85% of PV are septocutaneous (15% musculocutaneous). In women, 70.5% of PV are located in AC, 28.2% in CP, 1.2% in A, and 0% in P: average diameter of the PV is 2.4 +/- 0.3 mm. In men, 53.7% of PV are located in CP, 43.1% in AC, 3.3% in A, and 0% in P: average diameter of the PV is 2.8 +/- 0.5 mm. Gender-specific differences in anatomical distribution of PV are significant (P \u3c 0.001). Conclusions: Number, size, and type of terminal branches of PV of the IPA are consistent between genders, but their distribution is different, with women having an anterior predominance. Knowledge of gender-specific anatomy can guide preoperative planning and intraoperative dissection in flap-based perineal reconstruction

Neonatal cerebral ultrasound: anatomical variants and age-related diseases.

Cerebral ultrasound is a non-invasive imaging technique widely used for the assessment of brain anatomy and diseases in neonates and infants. Indeed, it allows a precise characterization of common variants such as cavum septum pellucidum or diseases like intraventricular hemorrhage. The aim of this pictorial review is to provide a comprehensive overview of the main ultrasound features of the most common cerebral anatomical variants and disorders detectable by cerebral ultrasound using an age-related approach which could support non-subspecialized radiologists
