From curing patients to healing society : the honourable Dr. Edward Che-hung Leong

Dr. Edward Che-hung Leong, GBM, GBS, OBE, JP, a private medical practitioner specialised in urology, was born into a medical family. Leong is well-known to most Hong Kong people for his surgery skills. He has been praised as the Golden Surgeon Leong (金刀梁). He is also named the Master of Public Office (公職王). Since 1988, he has been a Legislative Councilor representing the Medical Functional Constituency, as well as many other public service roles of the Government and quangos, including Chairmanship of the Elderly Commission, in which his works were highly appraised. For years Doctor Leung has enthusiastically engaged in serving the society. Recognising his contributions to the society, the government has awarded him the honours of Justice of Peace, Order of the British Empire, Gold Bauhinia Star, and Grand Bauhinia Medal. Dr. Leong is now serving as the Chairman of the University of Hong Kong Council, Chairman of the Committee on Elder Academy Development Foundation, Elderly Commission and other public service roles. There is an old saying that doctors can be classified into three classes, the best one cures the society; the middle the person; the lowest the sickness. How did Dr. Leong go through the process from curing patients to healing society

從「醫人」到「醫國」: 濟世為懷的梁智鴻醫生

梁智鴻醫生 (GBM，GBS，OBE，太平紳士) 出身醫學世家，是醫術高超的私人執業泌尿科醫生。他手術技巧高超，素有「金刀梁」的綽號，是香港家喻戶曉的一位名醫。他同時是一名「公職王」，自1988年起擔任過立法會醫學界功能界別議員以及安老事務委員會主席等多項政府及不同半官方機構的公職，一直深受各界人士好評。梁醫生多年來熱心公益；為肯定其對社會的貢獻，政府先後向他頒授多個勳銜，包括太平紳士、金紫荊星章以及大紫荊勳賢。現時梁醫生的主要公職包括香港大學校務委員會主席以及安老事務委員會長者學院發展基金主席等。有説「醫有三品: 上醫 醫國，中醫醫人，下醫醫病」，梁醫生是如何從「醫人」到「醫國」呢

Chiral Active Particles are Sensitive Reporter to Environmental Geometry

Chiral active particles (CAPs) are self-propelling particles that break time-reversal symmetry by orbiting or spinning, leading to intriguing behaviors. Here, we examined the dynamics of CAPs moving in 2D lattices of disk obstacles through active Brownian dynamics simulations and granular experiments with grass seeds. We find that the effective diffusivity of the CAPs is sensitive to the structure of the obstacle lattice, a feature absent in achiral active particles. We further studied the transport of CAPs in obstacle arrays under an external field and found a reentrant directional locking effect, which can be used to sort CAPs with different activities. Finally, we demonstrated that the parallelogram lattice of obstacles without mirror symmetry can separate clockwise and counter-clockwise CAPs. The mechanisms of the above three novel phenomena are qualitatively explained. As such, our work provides a basis for designing chirality-based tools for single-cell diagnosis and separation, and active particle-based environmental sensors

Prevalence and correlates of subjective cognitive impairment in Chinese psychiatric patients during the fifth wave of COVID-19 in Hong Kong

IntroductionThe extent of cognitive impairment and its association with psychological distress among people with pre-existing mental illness during COVID-19 is understudied. This study aimed to investigate prevalence and correlates of subjective cognitive impairment (SCI) in Chinese psychiatric patients during fifth-wave of COVID-19 in Hong Kong (HK).MethodsFour-hundred-eight psychiatric outpatients aged 18–64 years were assessed with questionnaires between 28 March and 8 April 2022, encompassing illness profile, psychopathological symptoms, coping-styles, resilience, and COVID-19 related factors. Participants were categorized into moderate-to-severe and intact/mild cognitive impairment (CI+ vs. CI-) groups based on severity of self-reported cognitive complaints. Univariate and multivariate regression analyses were conducted to determine variables associated with CI+ status.ResultsOne-hundred-ninety-nine participants (48.8%) experienced CI+. A multivariate model on psychopathological symptoms found that depressive and post-traumatic-stress-disorder (PTSD)-like symptoms were related to CI+, while a multivariate model on coping, resilience and COVID-19 related factors revealed that avoidant coping, low resilience and more stressors were associated with CI+. Final combined model demonstrated the best model performance and showed that more severe depressive and PTSD-like symptoms, and adoption of avoidant coping were significantly associated with CI+.ConclusionAlmost half of the sample of psychiatric patients reported cognitive complaints during fifth-wave of COVID-19 in HK. Greater depressive and PTSD-like symptom severity, and maladaptive (avoidant) coping were found as correlates of SCI. COVID-19 related factors were not independently associated with SCI in psychiatric patients. Early detection with targeted psychological interventions may therefore reduce psychological distress, and hence self-perceived cognitive difficulties in this vulnerable population

Moment-To-moment affective dynamics in schizophrenia and bipolar disorder

Background: Affective disturbances in schizophrenia and bipolar disorder may represent a transdiagnostic etiological process as well as a target of intervention. Hypotheses on similarities and differences in various parameters of affective dynamics (intensity, successive/acute changes, variability, and reactivity to stress) between the two disorders were tested.Methods: Experience sampling method was used to assess dynamics of positive and negative affect, 10 times a day over 6 consecutive days. Patients with schizophrenia (n = 46) and patients with bipolar disorder (n = 46) were compared against age-matched healthy controls (n = 46).Results: Compared to controls, the schizophrenia group had significantly more intense momentary negative affect, a lower likelihood of acute changes in positive affect, and reduced within-person variability of positive affect. The bipolar disorder group was not significantly different from either the schizophrenia group or the healthy control group on any affect indexes. Within the schizophrenia group, level of depression was associated with weaker reactivity to stress for negative affect. Within the bipolar disorder group, level of depression was associated with lower positive affect.Conclusions: Patients with schizophrenia endured a more stable and negative affective state than healthy individuals, and were less likely to be uplifted in response to happenings in daily life. There is little evidence that these affective constructs characterize the psychopathology of bipolar disorder; such investigation may have been limited by the heterogeneity within group. Our findings supported the clinical importance of assessing multiple facets of affective dynamics beyond the mean levels of intensity.</p
