    Abstract Purpose: To determine refractive or biometric variables that might be predictive of increased intermediate vision in patients receiving an Eyhance monofocal intraocular lens (IOL).
    Methods: This prospective, single-center, bilateral, non-randomized, open-label, observational study included a total of 110 subjects (220 eyes). Subjects had been previously bilaterally implanted with an Eyhance monofocal IOL (Johnson & Johnson Vision Care, Inc.) and were later divided into 2 groups based on their postoperative visual acuity. Subjects that had binocular distance corrected intermediate visual acuity (DCIVA) of 0.2 logMAR or better were classified into the Enhanced Group, and the remaining subjects were classified into the Non-Enhanced Group. Refractive outcomes and biometric measurements were compared between groups.
    Results: The number of subjects in each group was 61 for the Enhanced Group, and 49 for the Non-Enhanced Group. There were significant differences in pupil size between groups, with pupil sizes in the Enhanced Group significantly smaller than in the Non-Enhanced Group (p < 0.01). Subjects also reported significantly more dysphotopsias in the Non-Enhanced Group compared to the Enhanced Group (p = 0.03). Multiple regression analysis identified pupil size and axial length as significant predictors of increased monocular intermediate vision.
    Conclusion: The results of this study suggest that pupil size could be a predictor of increased intermediate vision in a patient receiving an Eyhance monofocal IOL.

    Abstract Noncovalent bonding between atmospheric molecules is central to the formation of aerosol particles and cloud condensation nuclei and, consequently, radiative forcing. While our understanding of O-H⋯B interactions is well developed, S-H⋯B hydrogen bonding has received far less attention. Sulfur- and nitrogen-containing molecules, particularly amines, play a significant role in atmospheric chemistry, yet S-H⋯N interactions are not well understood at a fundamental level. To help characterize these systems, H2S and methyl-, ethyl-, n-propyl-, dimethyl-, and trimethylamine (MA, EA, n-PA, DMA, and TMA) have been investigated using matrix isolation Fourier transform infrared spectroscopy and high-level theoretical methods. Experiments showed that H2S forms hydrogen bonded complexes with each of the amines, with bond strengths following the trend MA ≈ EA ≈ n-PA < TMA ≤ DMA, in line with past experimental work on H2SO4·amine complexes. However, the calculated results indicated that the trend should be MA < DMA < TMA, in line with past theoretical work on H2SO4·amine complexes. Evidence of strong Fermi resonances indicated that anharmonicity may play a critical role in the stabilization of each complex. The theoretical results were able to replicate experiment only after binding energies were recalculated to include the anharmonic effects. In the case of H2SO4·amine complexes, our results suggest that the discrepancy between theory and experiment could be reconciled, given an appropriate treatment of anharmonicity.

    Title translation Étude prospective des préoccupations financières, des changements de l’état de santé mentale et de l’effet modérateur du soutien social chez les adolescents canadiens pendant la pandémie de COVID-19.
    Abstract Introduction: The COVID-19 pandemic intensified the impact of risk factors for adolescent mental health, including financial worry. Social support has shown to protect from negative mental health during times of stress. We examined the effect of financial worry on changes in anxiety and depression symptoms among Canadian adolescents prior to and during the pandemic, and assessed whether social support from family and friends moderated any changes.
    Methods: We analyzed 2-year linked data from the 2018/19 (pre-pandemic) and 2020/21 (during-pandemic) waves of the COMPASS study, with reports from 12 995 Canadian secondary school students. A series of multilevel linear regressions were conducted to examine the main hypotheses under study.
    Results: Students scored an average (SD) of 7.2 (5.8) on the anxiety (GAD-7) and 10.0 (6.5) on the depression (CESD-10) scales; 16.1% reported they experienced financial worry during the pandemic. Financial worry was a strong and significant predictor of increased anxiety scores (+1.7 score between those reporting "true/mostly true" versus "false/mostly false") during the pandemic, but not for depression scores. Low family and friend support were associated with anxiety, and low family support was associated with depression. No significant interactions were detected between social support and financial worry.
    Conclusions: Pandemic-related financial worry was significantly associated with anxiety in our large sample of Canadian adolescents. Clinical and public health initiatives should be aware of adolescents' financial worry and its associations with anxiety during times of crisis.

    Abstract Objectives: To investigate the joint, prospective associations of physical inactivity and insomnia symptoms and productivity using the 2013 and 2014 household income and labor dynamics in Australia Survey panel data.
    Methods: The association between (i) presenteeism (yes/no, n = 5864) and (ii) absenteeism (sick leave days, n = 4324) and the mutually exclusive groups "active without insomnia," "active with insomnia," "inactive without insomnia," and "inactive with insomnia" was assessed.
    Results: Participants "active with insomnia" or "inactive with insomnia" had greater odds of presenteeism than those "active without insomnia" (odds ratio [OR] = 1.41, 95% confidence interval [CI]: 1.07 to 1.85 and OR = 1.44, 95% CI: 1.14 to 1.83, respectively). Participants "inactive with insomnia" had a greater incidence of absenteeism than participants "active without insomnia" (incidence rate ratio [IRR] = 1.28, 95% CI: 1.07 to 1.54).
    Conclusions: Findings suggest improving physical activity levels and insomnia symptoms concurrently may improve productivity by reducing presenteeism and sick leave.
