The 2015 outbreak of Middle East respiratory syndrome (MERS) in the Republic of Korea is the largest outbreak outside the Middle East since MERS was discovered in 2012. Its origin was a single imported case after the patient travelled to endemic countries.

Transient cortical blindness (TCB) is a rare but well-known complication of cerebral angiography. Its pathophysiology remains uncertain. We would like to report a case of TCB in a patient during a follow up vertebral angiogram for post-coil embolization of left posterior inferior cerebellar artery aneurysm. Patient's vision was resumed spontaneously within 24 hours after angiography, with no residual neurological deficit in subsequent clinical follow up. Multi-modality imaging evaluation including vertebral angiography, brain CT and MRI performed on same day are presented.

Background:Global Handwashing Day (GHD) is a handwashing promotion campaign organized by the Global Public-Private Partnership of Handwashing with Soap. In China, it has been promoted by the Chinese public health authorities, international organizations and multinational corporations through various channels including social media such as Sina Weibo, the leading Chinese microblogging site similar to Twitter. The objective of this study is to qualitatively assess Chinese social media users’ reactions to a health promotion campaign using Global Handwashing Day (GHD) 2012 as an example.Methods:We conducted a qualitative content analysis of 552 Weibo posts generated on GHD 2012 by Weibo users with 1000 or more followers with the Chinese keyword for “handwashing.” We categorized the Weibo posts into groups by keywords that frequently appeared in the data set. These groups were either exact reposts of an original post, or they conveyed similar information.Results:We observed the interconnections between traditional media and social media in handwashing promotion. Social media were found to serve as amplifiers of contents provided by traditional media. We observed the contextualization of global hygiene messages in a unique national social media market in China.Discussion:Our study showed that social media and traditional media are two interconnected arms of the GHD campaign in China. Our analysis demonstrated that public health campaigns in China can be evaluated using social media data. The themes and topics identified in this study will help public health practitioners evaluate future social media handwashing promotion campaigns.

Purpose:
This study aimed to evaluate the role of gallium-67 single photon emission computed tomography (SPECT) with contrast computed tomography (CT) in the evaluation and monitoring of infected abdominal aortic aneurysms (IAAA).
Materials and Methods:
A retrospective cohort analysis was performed using prospectively collected data of consecutive patients with IAAA in Princess Margaret Hospital in Hong Kong between January 2010 and December 2020. The patients were identified using the Radiology Information System.
Results:
All five patients had proven IAAA on CT and/or metabolic imaging.Among them, three were further supported by positive blood culture results. Gallium-67 SPECT with contrast CT was useful in the detection of residual disease, monitoring, and detection of recurrence.
Conclusion
Gallium-67 SPECT with contrast CT is helpful for evaluating IAAA.It serves an important role in guiding management, especially during long-term follow-up.

Purpose:
To investigate the effect of androgen deprivation therapy (ADT) on health-related quality of life (HRQOL) in Asian men with all stages of prostate cancer.
Materials and Methods:
READT (real-life evaluation of the effect of ADT in prostate cancer patients in Asia) was a multi-center, prospective observational study involving six sites across four Asian populations. We enrolled eligible prostate cancer patients, who opted for ADT alone or in combination without prior neoadjuvant or adjuvant ADT within 12 months. The EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L) utility index scores and visual analog scale (VAS) were evaluated at baseline, month 6 and month 12.
Results:
A total of 504 patients were recruited into READT between September 2016 and May 2020 with 52.9% diagnosed with metastatic prostate cancer. The EQ-5D-5L was evaluable in 442/504 (87.7%) of patients. Overall baseline EQ-5D-5L utility index score was 0.924 (interquartile range [IQR] 0.876–1.000). We observed a statistically significant difference in baseline EQ-5D-5L utility index score among different populations with a median EQ-5D-5L utility index score of 1 for Taiwan & Hong Kong, 0.897 for China and 0.838 for Malaysia. Similar trend was observed throughout multiple treatment time-points. Stage IV prostate cancer were significantly associated with a lower baseline EQ-5D-5L utility index score compared to stage I–III prostate cancer, producing a median disutility value of -0.080. Participants had a high median VAS (80, IQR 70–90), indicating good overall health on average during ADT initiation.
Conclusions
The study highlights the differences in health state utility index scores among various Asian prostate cancer patients receiving ADT at real-world setting. Our findings will be informative and useful in cost-effectiveness evaluation and policy decision making.

It is largely unknown whether lower urinary tract symptoms (LUTS) or acute retention of urine (AROU) is linked to shorter life expectancy in men. We conducted a multicenter, retrospective database analysis of patients undergoing transurethral resection of prostate (TURP) to study their relationships. Multivariate Cox regression analysis and Kaplan-Meier analysis with stratification to age and indication of TURP were performed. We further performed an age- and sex-matched survival analysis with the general population using data from the Census and Statistics Department of the Hong Kong Special Administrative Region (Hong Kong, China). From January 2002 to December 2012, 3496 patients undergoing TURP were included in our study, with 1764 patients in the LUTS group and 1732 patients in the AROU group. Old age, ischemic heart disease, cerebrovascular accident, and AROU were risk factors of mortality. Patients aged <70 years (adjusted hazard ratio [HR]: 1.52, 95% confidence interval [CI]: 1.11-2.09, P = 0.010) and 70-80 years (adjusted HR: 1.39, 95% CI: 1.15-1.70, P = 0.001) in the AROU group had worse survival than those in the LUTS group, but such difference was not demonstrated in patients aged >80 years. Compared to the general population, younger patients in the LUTS group appeared to have better survival (<70 years, P = 0.091; 70-80 years, P = 0.011), but younger patients in the AROU group had worse survival (<70 years, P = 0.021; 70-80 years, P = 0.003). For patients aged >80 years, survival was similar with the general population in both the LUTS and AROU groups. In conclusion, AROU at young age was associated with mortality, while early detection and management of LUTS may improve survival.

OBJECTIVETo assess the biological effects of the six-herb mixture Anti-Insomia Formula (AIF) extract using caffeine-induced insomnia Drosophila model and short-sleep mutants.
METHODSCaffeineinduced insomnia wild-type Drosophila and short-sleep mutant flies minisleep (mns) and Hyperkinetic(Y) (Hk(Y)) were used to assess the hypnotic effects of the AIF in vivo. The night time activity, the amount of night time sleep and the number of sleep bouts were determined using Drosophila activity monitoring system. Sleep was defined as any period of uninterrupted behavioral immobility (0 count per minute) lasting > 5 min. Night time sleep was calculated by summing up the sleep time in the dark period. Number of sleep bouts was calculated by counting the number of sleep episodes in the dark period.
RESULTSAIF at the dosage of 50 mg/mL, effectively attenuated caffeine-induced wakefulness (P<0.01) in wild-type Canton-S flies as indicated by the reduction of the sleep bouts, night time activities and increase of the amount of night time sleep. AIF also significantly reduced sleeping time of short-sleep Hk(Y) mutant flies (P<0.01). However, AIF did not produce similar effect in mns mutants.
CONCLUSIONAIF might be able to rescue the abnormal condition caused by mutated modulatory subunit of the tetrameric potassium channel, but not rescuing the abnormal nerve firing caused by Shaker gene mutation. This study provides the scientific evidence to support the use of AIF in Chinese medicine for promoting sleep quality in insomnia.
