The mortality-to-incidence ratio (MIR) is widely used to evaluate the efficacy of cancer management outcomes for individual countries. However, the association among health care expenditure, human development index (HDI), and changes in MIR over time (δMIR) remains unknown. We aimed to elucidate the significance between these indicators and gastric cancer outcomes in different countries. Among the regions, Asia had the highest number of new gastric cancer cases, gastric cancer-related deaths, age-standardized ratio of incidence, and mortality. Chile had the highest age-standardized ratio (ASR) for gastric cancer incidence and the highest ASR for mortality. Moreover, MIR was highest in Africa (0.91) and lowest in North America (0.43). Of note, MIR was negatively associated with HDI, current health expenditure (CHE) per capita, and CHE/GDP % and δMIR was positively associated with CHE/GDP % in countries with very high HDI. However, δMIR showed no significant associations with these indicators in the countries analyzed. In conclusion, increased HDI, CHE per capita, and CHE/GDP are associated with improved gastric cancer outcomes. In addition, the δMIR could be an indicator that can be used to evaluate the improvement in cancer management outcomes over time.

Aim Good sleep quality is essential to physical and mental‐health‐related quality of life. The purpose of this study was to evaluate the effects of a walking exercise in relieving sleep quality, fatigue, and depression in new mothers during the postpartum period. Methods This quasi‐experimental study was conducted at a teaching hospital in southern Taiwan. One hundred and four eligible postpartum women with poor sleep quality (Postpartum Sleep Quality Scale; PSQS score ≧16) were assigned to either the experimental group (n = 50) or the control group (n = 54) according to their individual preferences. The participants in the experimental group participated in a 12‐week stride walking exercise intervention. The control group did not receive any exercise intervention. The PSQS, Postpartum Fatigue Scale, and Edinburgh Postnatal Depression Scale were used to assess outcomes. Results Repeated measures ANOVA demonstrated that the experimental group participants perceived milder physical symptoms associated with sleep inefficiency at 4‐week posttest (F = 7.25, p < 0.01) than their control group peers. However, no significant differences were found between two groups in terms of either fatigue or depression at 4‐week and 12‐week posttest. Conclusion Significant improvement in the physical symptoms associated with sleep inefficiency was observed. The findings may be used to encourage postpartum women with disordered sleep to incorporate 20–30 min of stride walking into their regular routine to improve sleep quality.

Prenatal depression is a painful growth experience represented by silent and unbalanced commitment during the maternal role transition. Our findings may help healthcare professionals to understand the vulnerable experiences of pregnant women and devise preventive intervention strategies, such as prenatal education for both parents and comprehensive screening for prenatal depression in at-risk pregnant women, so that they are better prepared for the transition to motherhood.

Hydro(solvo)thermal reactions of N,N'-di(3-methylpyridyl)oxalamide (L1) and N,N'-di(4-methylpyridyl)oxalamide (L2) with angular dicarboxylic acids and Zn(II) and Co(II) metal salts afforded six coordination polymers (CPs), namely, [Zn(L1)0.5(FIPBB)·H2O]n [H2FIPBB = 4,4’-hexafluoroisopropylidenebis(benzoic acid)], 1,...

Hg(II) halide complexes [HgCl2] 2L1 [L1 = N,N’-bis(3-pyridyl)bicyclo(2,2,2,)oct-7-ene-2,3,5,6-tetracarboxylic diamide), 1, [HgBr2(L1)]n, 2, [HgI2(L1)], 3, [Hg2X4(L2)2] [X = Cl, 4, Br, 5, and I, 6; L2 = N,N’-bis(4-pyridylmethyl)bicyclo(2,2,2,)oct-7-ene-2,3,5,6-tetracarboxylic diamide] and {[HgX2(L3)]×H2O}n [X = Cl, 7, Br, 8 and I, 9; L3 = 4,4′-oxybis(N-(pyridine-3-yl)benzamide)] are reported and structurally characterized using single-crystal X-ray diffraction analyses. The linear HgCl2 units of complex 1 are interlinked by the L1 ligands through Hg---N and Hg---O interactions, resulting in 1D supramolecular chains. Complex 2 shows 1D zigzag chains interlinked through the Br---Br interactions to form 1D looped supramolecular chains, while the mononuclear [HgI2L2] molecules of 3 are interlinked through Hg---O and I---I interactions, forming 2D supramolecular layers. Complexes 4–6 are isomorphous dinuclear metallocycles, and 7–9 form isomorphous 1D zigzag chains. The roles of the ligand type and the halide anion in determining the structural diversity of 1–9 is discussed and the luminescent properties of 7–9 evaluated. Complexes 7–9 manifest stability in aqueous environments. Moreover, complexes 7 and 8 show good sensing towards Fe3+ ions with low detection limits and good reusability up to five cycles, revealing that the Hg-X---Fe3+ (X = Cl and Br) interaction may have an important role in determining the quenching effect of 7 and 8.
