MENOS4 trial: a multicentre randomised controlled trial (RCT) of a breast care nurse delivered cognitive behavioural therapy (CBT) intervention to reduce the impact of hot flushes in women with breast cancer: Study Protocol

BACKGROUND: Women who have been treated for breast cancer may identify vasomotor symptoms, such as hot flushes and night sweats (HFNS), as a serious problem. HFNS are unpleasant to experience and can have a significant impact on daily life, potentially leading to reduced adherence to life saving adjuvant hormonal therapy. It is known that Cognitive Behavioural Therapy (CBT) is effective for the alleviation of hot flushes in both well women and women who have had breast cancer. Most women with breast cancer will see a breast care nurse and there is evidence that nurses can be trained to deliver psychological treatments to a satisfactory level, whilst also maintaining treatment fidelity. The research team will assess whether breast care nurses can effectively deliver a CBT intervention to alleviate hot flushes in women with breast cancer.METHODS: This study is a multi-centre phase III individually randomised controlled trial of group CBT versus usual care to reduce the impact of hot flushes in women with breast cancer. 120-160 women with primary breast cancer experiencing seven or more problematic HFNS a week will be randomised to receive either treatment as usual (TAU) or participation in the group CBT intervention plus TAU (CBT Group). A process evaluation using May's Normalisation Process Theory will be conducted, as well as practical and organisational issues relating to the implementation of the intervention. Fidelity of implementation of the intervention will be conducted by expert assessment. The cost effectiveness of the intervention will also be assessed.DISCUSSION: There is a need for studies that enable effective interventions to be implemented in practice. There is good evidence that CBT is helpful for women with breast cancer who experience HFNS, yet it is not widely available. It is not yet known whether the intervention can be effectively delivered by breast care nurses or implemented in practice. This study will provide information on both whether the intervention can effectively help women with hot flushes and whether and how it can be translated into routine clinical practice.TRIAL REGISTRATION: ISRCTN 12824632 .

Continuous Low-Bias Switching of Superconductivity in a MoS2 Transistor

Engineering the properties of quantum electron systems, e.g., tuning the superconducting phase using low driving bias within an easily accessible temperature range, is of great interest for exploring exotic physical phenomena as well as achieving real applications. Here, the realization of continuous field-effect switching between superconducting and non-superconducting states in a few-layer MoS2 transistor is reported. Ionic-liquid gating induces the superconducting state close to the quantum critical point on the top surface of the MoS2, and continuous switching between the super/non-superconducting states is achieved by HfO2 back gating. The superconducting transistor works effectively in the helium-4 temperature range and requires a gate bias as low as approximate to 10 V. The dual-gate device structure and strategy presented here can be easily generalized to other systems, opening new opportunities for designing high-performance 2D superconducting transistors

Project 27/28: inquiry into quality of neonatal care and its effect on the survival of infants who were born at 27 and 28 weeks in England, Wales, and Northern Ireland.

OBJECTIVE: To identify variations in standards of neonatal care in the first week of life that might have contributed to deaths in infants who were born at 27 and 28 weeks' gestation. METHODS: A case-control study was conducted of infants who were born at 27 and 28 weeks' gestation in England, Wales, and Northern Ireland during a 2-year period. Cases were neonatal deaths; control subjects were randomly selected survivors at day 28. Main outcome measures were failures of prespecified standards of care or deficiencies in care reported by regional panels assessing anonymized medical records. RESULTS: Failures of standards of care relating to ventilatory support (adjusted odds ratio [OR]: 3.29; 95% confidence interval [CI]: 1.97-5.49), cardiovascular support (OR: 2.37; 95% CI :1.36-4.13), and thermal care (OR: 1.71; 95% CI: 1.21-2.43) were associated with neonatal death. Frequencies of unmet resuscitation standards (range: 3%-46%) and of delays in surfactant administration (range: 38%-40%) were similar in cases and control subjects. Panels identified significantly more deficiencies in all aspects of neonatal care in cases with the exception of the management of infection. Stratification by clinical condition of infants at birth showed a stronger association between overall standard of care and death when infants were in a good condition at birth. CONCLUSIONS: Our findings suggest an association between quality of neonatal care and neonatal deaths, most marked for early thermal care and ventilatory and cardiovascular support. Poor overall quality of care was more strongly associated with deaths when the infant was in a good condition at birth
