Levobupivacaine inhibits proliferation and promotes apoptosis of breast cancer cells by suppressing the PI3K/Akt/mTOR signalling pathway.

OBJECTIVE: This study aimed to test the hypothesis that levobupivacaine has anti-tumour effects on breast cancer cells. RESULTS: Colony formation and transwell assay were used to determine breast cancer cells proliferation. Flow Cytometry (annexin V and PI staining) was used to investigate breast cancer cells apoptosis. The effects of levobupivacaine on cellular signalling and molecular response were studied with Quantitative Polymerase Chain Reaction and western blot. Induction of apoptosis was confirmed by cell viability, morphological changes showed cell shrinkage, rounding, and detachments from plates. The results of the western blot and Quantitative Polymerase Chain Reaction indicated activation of active caspase-3 and inhibition of FOXO1. The results of the flow Cytometry confirmed that levobupivacaine inhibited breast cancer cell proliferation and enhanced apoptosis of breast cancer cells. Quantitative Polymerase Chain Reaction and Western blot analysis showed increased p21 and decreased cyclin D. Quantitative Polymerase Chain Reaction and western blot analysis showed that levobupivacaine significantly increased Bax expression, accompanied by a significant decreased Bcl-2 expression and inhibition of PI3K/Akt/mTOR signalling pathway. These findings suggested that levobupivacaine inhibits proliferation and promotes breast cancer cells apoptosis in vitro.

Pilot testing of the Becoming Breastfeeding Friendly toolbox in Ghana.

BACKGROUND: Ghana has achieved significant progress in breastfeeding practices in the past two decades. Further progress is, however, limited by insufficient government funding and declining donor support for breastfeeding programs. The current study pretested feasibility of the Becoming Breastfeeding Friendly (BBF) toolbox in Ghana, to assess the existing enabling environment and gaps for scaling-up effective actions. METHODS: Between June 2016 and April 2017, a 15-person expert country committee drawn from government and non-government agencies was established to implement the BBF toolbox. The committee used the BBF index (BBFI), comprising of 54 benchmarks and eight gears of the Breastfeeding Gear Model (advocacy; political will; legislation and policy; funding and resources; training and program delivery; promotion; research and evaluation; and coordination, goals and monitoring). Available evidence (document reviews, and key informant interviews) was used to arrive at consensus-scoring of benchmarks. Benchmark scores ranged between 0 (no progress) and 3 (major progress). Scores for each gear were averaged to estimate the Gear Total Score (GTS), ranging from 0 (least) to 3.0 (strong). GTS's were aggregated as a weighted average to estimate the BBFI which ranged from 0 (weak) to 3.0 (outstanding). Gaps in policy and program implementation and recommendations were proposed for decision-making. RESULTS: The BBFI score was 2.0, indicating a moderate scaling-up environment for breastfeeding in Ghana. Four gears recorded strong gear strength: advocacy (2.3); political will (2.3); legislation and policy (2.3); and coordination, goals and monitoring (2.7). The remaining four gears had moderate gear strength: funding and resources (1.3); training and program delivery (1.9); promotion (2.0); and research and evaluation (1.3). Key policy and program gaps identified by the committee included sub-optimal coordination across partners, inadequate coverage and quality of services, insufficient government funding, sub-optimal enforcement of policies, and inadequate monitoring of existing initiatives. Prioritized recommendations from the process were: 1) strengthen advocacy and empower breastfeeding champions, 2) strengthen breastfeeding regulations, including maternity protection, 3) strengthen capacity for providing breastfeeding services, and 4) expand and sustain breastfeeding awareness initiatives. CONCLUSIONS: The moderate environment for scaling-up breastfeeding in Ghana can be further strengthened by addressing identified gaps in policy and programs.
