    As the epidemic of COVID-19 is gradually controlled in China, a summary of epidemiological characteristics and interventions may help control its global spread.

    Data for COVID-19 cases in Hubei Province (capital, Wuhan) was extracted until 7 March 2020. The spatiotemporal distribution of the epidemic in four periods (before 10 January, 10-22 January, 23 January-6 February and 7 February-7 March) was evaluated, and the impacts of interventions were observed.

    Among 67 706 COVID-19 cases, 52 111 (76.97%) were aged 30-69 years old, and 34 680 (51.22%) were women. The average daily attack rates (95% CI) were 0.5 (0.3 to 0.7), 14.2 (13.2 to 15.1), 45.7 (44.0 to 47.5) and 8.6 (7.8 to 9.3) cases per 10

    people in four periods, and the harmonic means (95% CI) of doubling times were 4.28 (4.01 to 4.55), 3.87 (3.78 to 3.98), 5.40 (4.83 to 6.05) and 45.56 (39.70 to 52.80) days. Homoharringtonine solubility dmso Compared with the first period, daily attack rates rose rapidly in the second period. In the third period, 14 days after 23 January, the daily average attack rate in and outside Wuhan declined by 33.8% and 48.0%; the doubling times increased by 95.0% and 133.2%. In the four periods, 14 days after 7 February, the daily average attack rate in and outside Wuhan decreased by 79.1% and 95.2%; the doubling times increased by 79.2% and 152.0%.

    The public health interventions were associated with a reduction in COVID-19 cases in Hubei Province, especially in districts outside of Wuhan.

    Malignant and non-malignant respiratory diseases account for >4.6 million deaths annually worldwide. Despite similar symptom burdens, serious inequities in access to palliative care persists for people with non-malignant respiratory diseases.

    To compare functional decline and symptom distress in advanced malignant and non-malignant lung diseases using consecutive, routinely collected, point-of-care national data.

    The Australian national Palliative Care Outcomes Collaboration collects

    (Australia-modified Karnofsky Performance Status (AKPS)) and

    (patient-reported 0-10 numerical rating scale) in inpatient and community settings. Five years of data used Joinpoint and weighted scatterplot smoothing.

    In lung cancers (89 904 observations; 18 586 patients) and non-malignant end-stage respiratory diseases (14 827 observations; 4279 patients), age at death was significantly lower in people with lung cancer (73 years; IQR 65-81) than non-malignant end-stage respiratory diseases (81 years; IQR 73-87 years; p<0.001). Four months before death, median AKPS was 40 in lung cancers and 30 in non-malignant end-stage respiratory diseases (p<0.001). Functional decline was similar in the two groups and accelerated in the last month of life. People with non-malignant diseases accessed palliative care later.Pain-related distress was greater with cancer and breathing-related distress with non-malignant disease. Breathing-related distress increased towards death in malignant, but decreased in non-malignant disease. Distress from fatigue and poor sleep were similar for both.

    In this large dataset unlike previous datasets, the pattern of functional decline was similar as was overall symptom burden. Timely access to palliative care should be based on needs not diagnoses.

It has been claimed that humans can acquire physiological responses to threat-associated stimuli even when they are unaware of them, but the role of awareness in updating threat contingencies remains unknown. This complex process-generating novel responses while suppressing learned ones-relies on distinct neural mechanisms from initial learning, and has only been shown with awareness. Can it occur unconsciously? Here, we present evidence that threat reversal may not require awareness. Participants underwent classical threat conditioning to visual stimuli that were suppressed from awareness. One of two images was paired with an electric shock; halfway through the experiment, contingencies were reversed and the shock was paired with the other image. Despite variations in suppression across participants, we found that physiological responses reflected changes in stimulus-threat pairings independently of stimulus awareness. These findings suggest that unconscious affective processing may be sufficiently flexible to adapt to changing circumstances.Conditioned stimuli (CS) have multiple psychological functions that can potentially contribute to their effect on memory formation. It is generally believed that CS-induced memory modulation is primarily due to conditioned emotional responses, however, well-learned CSs not only generate the appropriate behavioral and physiological reactions required to best respond to an upcoming unconditioned stimulus (US), but they also serve as signals that the US is about to occur. Therefore, it is possible that CSs can impact memory consolidation even when their ability to elicit conditioned emotional arousal is significantly reduced. To test this, male Sprague-Dawley rats trained on a signaled active avoidance task were divided into “Avoider” and “Non-Avoider” subgroups on the basis of percentage avoidance after 6 d of training. Subgroup differences in responding to the CS complex were maintained during a test carried out in the absence of the US. Moreover, the subgroups displayed significant differences in stress-induced analgesia (hot-plate test) immediately after this test, suggesting significant subgroup differences in conditioned emotionality. Importantly, using the spontaneous object recognition task, it was found that immediate post-sample exposure to the avoidance CS complex had a similar enhancing effect on object memory in the two subgroups. Therefore, to our knowledge, this is the first study to demonstrate that a significant conditioned emotional response is not necessary for the action of a predictive CS on modulation of memory consolidation.
