BackgroundRehabilitation of horses using underwater treadmill therapy has been shown to improve joint range of motion, joint mobility, stride length and proprioceptive parameters with experimental studies. However, studies investigating the prognosis and return to function following rehabilitation are lacking.MethodsA retrospective study of Thoroughbred racehorses treated with arthroscopic surgery for osteochondral fragments of the metacarpophalangeal (MCP) or metatarsophalangeal (MTP) joints or carpal joints undergoing conventional rehabilitation or underwater treadmill assisted rehabilitation at the same facility were included. The objective of the current study was to investigate if underwater treadmill assisted rehabilitation following arthroscopy in the Thoroughbred racehorse was positively associated with returning to racing, time to return to racing and postoperative racing performance including Beyer Speed Figures.ResultsSurgery was performed on 165 horses on 174 surgical occasions; 70 (40.2 per cent) underwent underwater treadmill rehabilitation, with the remainder undergoing conventional rehabilitation. The time to return to racing was a median of 227 (IQR 185–281) days and 239 (IQR 205–303) days for underwater treadmill and conventional rehabilitation, respectively (P=0.16). Of the horses that raced presurgery, 83 per cent (58/70) of underwater treadmill rehabilitated horses and 61 per cent (63/104) of horses undergoing conventional rehabilitation returned to racing following surgery (P=0.02).ConclusionUnderwater treadmill rehabilitation is superior in returning a Thoroughbred racehorse to racing following arthroscopic surgery of the carpus and/or MCP/MTP joints.

Findings of the association between hot weather and suicide in a subtropical city such as Hong Kong are inconsistent. This study aimed to revisit the association by identifying meteorological risk factors for older-adult suicides in Hong Kong using a time-series approach. A retrospective study was conducted on older-adult (aged ≥65) suicide deaths in Hong Kong from 1976 to 2014. Suicides were classified into those involving violent methods and those involving nonviolent methods. Meteorological data, including ambient temperature, were retrieved. Transfer function time-series models were fitted. In total, 7314 older-adult suicide deaths involving violent methods and 630 involving nonviolent methods were recorded. For violent-method suicides, a monthly average daily minimum ambient temperature was determined to best predict the monthly rate, and a daily maximum ambient temperature of 30.3 °C was considered the threshold. For suicide deaths involving nonviolent methods, the number of days in a month for which the daily maximum ambient temperature exceeded 32.7 °C could best predict the monthly rate. Higher ambient temperature was associated with more older-adult suicide deaths, both from violent and nonviolent methods. Weather-focused preventive measures for older-adult suicides are necessary, such as the provision of more public air-conditioned areas where older adults can shelter from extreme hot weather.

Abstract Background Currently there are only two population studies on sepsis incidence in Asia. The burden of sepsis in Hong Kong is unknown. We developed a sepsis surveillance method to estimate sepsis incidence from a population electronic health record (EHR) in Hong Kong using objective clinical data. The study objective was to assess our method’s performance in identifying sepsis using a retrospective cohort. We compared its accuracy to administrative sepsis surveillance methods such as Angus’ and Martin’s methods. Method In this single centre retrospective study we applied our sepsis surveillance method on adult patients admitted to a tertiary hospital in Hong Kong. Two clinicians independently reviewed the clinical notes to determine which patients had sepsis. Performance was assessed by sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) of Angus’, Martin’s and our surveillance methods using clinical review as “gold standard.” Results Between January 1 and February 28, 2018, our sepsis surveillance method identified 1352 adult patients hospitalised with suspected infection. We found that 38.9% (95%CI 36.3–41.5) of these patients had sepsis. Using a 490 patient validation cohort, two clinicians had good agreement with weighted kappa of 0.75 (95% CI 0.69–0.81) before coming to consensus on diagnosis of uncomplicated infection or sepsis for all patients. Our method had sensitivity 0.93 (95%CI 0.89–0.96), specificity 0.86 (95%CI 0.82–0.90) and an AUC 0.90 (95%CI 0.87–0.92) when validated against clinician review. In contrast, Angus’ and Martin’s methods had AUCs 0.56 (95%CI 0.53–0.58) and 0.56 (95%CI 0.52–0.59), respectively. Conclusions A sepsis surveillance method based on objective data from a population EHR in Hong Kong was more accurate than administrative methods. It may be used to estimate sepsis population incidence and outcomes in Hong Kong. Trial registration This study was retrospectively registered at clinicaltrials.gov on October 3, 2019 (NCT04114214).
