Work experience of breastfeeding nurses returning to work after maternity leave in Liaoning Province of China: A qualitative study.

AIM: With the implementation of China's three-child policy in 2021, the nurse population faces an increase in the number of breastfeeding nurses returning to work after maternity leave. This study aims to describe the work experience of breastfeeding nurses returning to work after maternity leave. DESIGN: A qualitative descriptive design. METHODS: The data were collected through semi-structured interviews with eight nurses and analysed through Braun and Clarke's thematic analysis. RESULTS: Three themes and nine sub-themes emerged from the analysis of the interviews: changes in nurses (emotional changes, physical changes and changes in work); needs for an improving work environment (needs for a supportive workplace and nurse shortage); support for breastfeeding nurses (support from coworkers, support from the manager, support from the organisation and own need for work). PUBLIC CONTRIBUTION: This study highlighted that breastfeeding nurses need an adjustment period when they return to work after maternity leave. Successful breastfeeding requires support from coworkers, managers and the organisation. In addition, workplace support for breastfeeding and management for nurses needs to be improved.

Breathing exercises improve post-operative pulmonary function and quality of life in patients with lung cancer: A meta-analysis.

Previous research has shown that breathing exercises may improve the prognosis and health status in patients with lung cancer by enhancing pulmonary function and quality of life (QOL). However, individually published results are inconclusive. The aim of the present meta-analysis was to evaluate the clinical value of breathing exercises on post-operative pulmonary function and QOL in patients with lung cancer. A literature search of Pubmed, Embase, the Web of Science and CBM databases was conducted from their inception through to October 2012. Crude standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to assess the effect of breathing exercises. A total of eight clinical studies were ultimately included with 398 lung cancer patients. When all the eligible studies were pooled into the meta-analysis, there was a significant difference between the pre-intervention and post-intervention results of breathing exercises on post-operative pulmonary function; forced expiratory volume in 1 sec (FEV1): SMD, 3.37; 95% CI, 1.97-4.77; P<0.001; FEV1/FVC: SMD, 1.77; 95% CI, 0.15-3.39; P=0.032). Furthermore, the QOL in patients with lung cancer was significantly improved following the intervention with breathing exercises; there were significant differences between the pre-intervention and post-intervention results on the ability of self-care in daily life (SMD, -1.00; 95% CI, -1.467 to -0.52; P<0.001), social activities (SMD, -0.94; 95% CI, -1.73 to -0.15; P=0.02), symptoms of depression (SMD, -0.91; 95% CI, -1.25 to -0.57; P<0.001) and symptoms of anxiety (SMD, -0.91; 95% CI, -1.20 to -0.63; P<0.001). Results from the present meta-analysis suggest that breathing exercises may significantly improve post-operative pulmonary function and QOL in patients with lung cancer.

CASP-1, -2 and -5 gene polymorphisms and cancer risk: A review and meta-analysis.

Accumulating evidence suggests the CASP gene family is important in the development of carcinogenesis. These genetic polymorphisms have been extensively investigated as a potential risk factor for cancer, but results have been inconclusive. This Human Genome Epidemiology (HuGE) review and meta-analysis was performed to investigate the associations between CASP-1, -2 and -5 and cancer risk. A literature search of Pubmed, Embase, Web of Science and CBM databases was conducted from inception through September 1st, 2012. Four case-control studies with a total of 1,592 cancer cases and 1,833 healthy controls were included in the present meta-analysis. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. Five polymorphisms were examined, including rs501192 (G>A), rs4647297 (C>G), rs507879 (T>C), rs3181320 (G>C) and rs523104 (G>C). Meta-analysis results showed that the rs3181320*C allele/carrier were associated with increased risk of various types of cancers (OR=1.26; 95% CI, 1.04-1.54; P=0.020 and OR=1.33; 95% CI, 1.00-1.75; P=0.047, respectively). However, similar associations were not found in the rs501192, rs4647297, rs507879 and rs523104 polymorphisms (all P>0.05). Results from the current meta-analysis suggest that the rs3181320*C allele/carrier in CASP-5 gene are potential risk factors for cancer.

An unprecedented mu4-Sn2Se9 ligand: solvothermal syntheses and characterizations of novel lanthanum selenidostannates [{La(dien)2}4(mu4-Sn2Se9)(mu-Sn2Se6)]infinity and [La2(en)8(mu-Se2)]Sn2Se6.

Solvothermal reaction of La2O3, Sn and Se in dien yields a novel lanthanide selenidostannate [{La(dien)2}4(mu4-Sn2Se9)(mu-Sn2Se6)]infinity, the first example of the coordination of Sn2Se9 and Sn2Se6 ligands to hard Lewis acidic lanthanide metals, while the reaction in en yields an ionic compound [La2(en)8(mu-Se2)]Sn2Se6 containing a ten-coordinated binuclear lanthanum complex [La2(en)8(Se2)]4+ with the diselenide Se(2)(2-) group as a bridging ligand.
