Trends in health screening participation and lifestyle behaviours after participation in a free,access‐enhanced screening intervention in a low‐income Singaporean rental‐flat community

Our objective was to evaluate the impact of an access‐enhanced health screening intervention on screening adherence in a rental‐flat community. In Singapore, public rental flats provide heavily subsidised rentals for the needy who cannot afford to own their own homes; with a majority of Singaporeans (≥85%) staying in owner‐occupied public housing. We observed trends in health screening adherence and health behaviours among residents of a multi‐ethnic public rental‐flat community in Singapore from 2013 to 2017, after participation in a free, access‐enhanced multi‐modality screening programme in 2011. Residents staying in neighbouring owner‐occupied housing who participated in the same screening programme served as a basis of comparison. A total of 478 rental‐flat residents and 505 owner‐occupied flat residents participated. In the rental‐flat community, hypertension screening rates improved from 18.3% (24/131) in 2013, to 61.2% (52/85) in 2015 and 44.2% (34/77) in 2017 (p < .001). For diabetes, rates improved from 26.2% (43/164) → 47.0% (54/115) → 49.5% (45/91; p < .001). For dyslipidaemia screening, rates improved from 18.2% (31/170) → 39.6% (38/96) → 47.5% (38/80; p < .001). In the owner‐occupied community (n = 505), screening rates largely remained stagnant (hypertension: 52.2% → 75.0% → 54.5%, p = .059; diabetes: 66.0% → 56.5% → 66.7%, p = .434; dyslipidaemia: 53.1% → 50.0% → 57.1%, p = .818). In the rental‐flat community, unhealthy behaviours increased from 2013 to 2017, with higher proportions of overweight (30.4% → 24.8% → 52.1%, p < .001), higher smoking (11.7% → 36.9% → 32.5%, p < .001) and higher drinking rates (1.4% → 0.7% → 8.1%, p < .001). This shift was also reflected in the owner‐occupied community, with higher percentages of overweight and higher drinking rates (p < .001).

The development of cellular immunity to Epstein-Barr virus after allogeneic bone marrow transplantation

Epstein-Barr virus-induced lymphoproliferative disease (EBV-LPD) is a potentially lethal complication during the first 6 months after allogeneic bone marrow transplantation (BMT). To determine whether deficiencies of EBV-specific cellular immunity contribute to EBV-LPD susceptibility and distinguish patients at risk, we performed limiting dilution analysis to quantify anti-EBV cytotoxic T-lymphocyte precursor (CTLp) frequencies in 26 recipients of unmodified or T-cell-depleted (TCD) grafts from EBV-seropositive donors. At 3 months post-BMT (n = 26), only five patients had EBV CTLp frequencies in the range of seropositive normal controls, irrespective of the type of transplant administered. By 6 months post-BMT, 9 of 13 patients tested had EBV CTLp frequencies within the normal range. The time period in which these patients had deficient cellular immunity to EBV corresponds to the period in which we have observed EBV-LPD in most prior patients. One patient with a low EBV CTLp frequency at 4 months post-BMT developed an EBV-LPD. Within 2 weeks of receiving an infusion of donor peripheral blood mononuclear cells (PBMC) providing less than 1,200 EBV- specific cytotoxic T-cell precursors, populations of EBV-specific CTL in the circulation were restored to levels detected in normal seropositive adults. Concurrently, the patient achieved a regression of the EBV-LPD, which has been sustained without further therapy. These studies indicate that recipients of both unmodified and TCD marrow grafts have profound deficiencies of EBV-specific T cell-mediated immunity early posttransplant, and that the period of risk for EBV-LPD closely corresponds to this interval of severe deficiency. Treatment of one patient with EBV-LPD with marrow donor-derived PBMC induced a rapid expansion of EBV-specific cytotoxic T-cell populations that occurred contemporaneously with the clinical regression of disease.     

食管切除术后病人的护理

在美国,食管癌是死亡率最高的恶性肿瘤之一,男性多于女性,其发病率随年龄增长而增加。食管癌临床表现早期食管癌临床表现不明显,吞咽困难是最常见的初始症状,但由于食管壁的柔韧性,病人到晚期才感觉到,从不能吞咽固体开始,进展到最终不能吞咽液体。此外,病人还可有吞咽时疼痛、体重减轻、营养不良和虚弱等表现。晚期表现还包括胸骨后疼痛、呃逆、呼吸困难、胃烧灼感、口臭、声音嘶哑、咳嗽、流涎过多及夜间误吸等。食管切除术后病人的护理食管切除术后24~48 h病人在重症监护室度过,通常带有气管插管等多种导管,护士应加强心肺及各方面的监护…     

Non-HLA genes modulate the risk of rheumatoid arthritis associated with HLA-DRB1 in a susceptible North American Native population

Most of the genetic risk for rheumatoid arthritis (RA) is conferred by 'shared epitope' (SE), encoding alleles of HLA-DRB1. Specific North American Native (NAN) populations have RA prevalence rates of 2-5%, representing some of the highest rates estimated worldwide. As many NAN populations also demonstrate a high background frequency of SE, we sought to determine whether other genetic factors contribute to disease risk in this predisposed population. RA patients (n=333) and controls (n=490) from the Cree/Ojibway NAN population in Central Canada were HLA-DRB1 typed and tested for 21 single-nucleotide polymorphisms (SNPs) that have previously been associated with RA, including PTPN22, TRAF1-C5, CTLA4, PADI4, STAT4, FCRL3, CCL21, MMEL1-TNFRSF14, CDK6, PRKCQ, KIF5A-PIP4K2C, IL2RB, TNFAIP3, IL10-1082G/A and REL. Our findings indicate that SE is prevalent and represents a major genetic risk factor for RA in this population (82% cases versus 68% controls, odds ratio=2.2, 95% confidence interval 1.6-3.1, P<0.001). We also demonstrate that in the presence of SE, the minor allele of MMEL1-TNFRSF14 significantly reduces RA risk in a dominant manner, whereas TRAF1-C5 increases the risk. These findings point to the importance of non-HLA genes in determining RA risk in a population with a high frequency of disease predisposing HLA-DRB1 alleles.     

National survey of ophthalmologists in Singapore for the assessment and management of asymptomatic angle closure

PURPOSE: Approximately 10% of Chinese people older than 50 years in Singapore have asymptomatic narrow angles [also termed primary angle closure suspects (PACS)]. The aim of this study was to determine the attitudes and practices of ophthalmologists in Singapore regarding the management of these patients. METHODS: A nation wide questionnaire-based survey was conducted on all registered, practicing ophthalmologists in Singapore by electronic mail and post. An ophthalmologist was defined as a doctor who had completed at least 3 years of specialist training in ophthalmology and had passed the Master's Degree in Ophthalmology or equivalent examinations. The survey asked the ophthalmologists about the methods and criteria used for the diagnosis of angle closure. It also inquired about the management of PACS and opinions on the effectiveness of prophylactic laser peripheral iridotomy (LPI) in preventing both acute and chronic angle closure. RESULTS: A total of 126 out of 158 ophthalmologists responded (79.7% response rate). Of the respondents, 84.9% would advise prophylactic LPI for asymptomatic PACS; 84.9% believed that prophylactic LPI would prevent acute angle closure but only 44% thought that it could prevent the development of glaucomatous optic nerve damage. The preferred method of prophylactic LPI was sequential argon-YAG LPI. In assessing patients for angle closure, 85.4% used gonioscopy, 92.9% assessed anterior chamber depth, and 17.5% performed provocative tests. CONCLUSIONS: Ophthalmologists in Singapore vary in the method of assessment of patients with angle closure. Most believe that prophylactic LPI should be performed for asymptomatic PACS.     

Testicular Cancer Knowledge among Deaf and Hearing Men

Testicular cancer typically affects young and middle-aged men. An educational video about prostate and testicular cancer was created in American Sign Language, with English open captioning and voice overlay, so that it could be viewed by audiences of diverse ages and hearing characteristics. This study recruited young Deaf (n?=?85) and hearing (n?=?90) adult males to help evaluate the educational value of the testicular cancer portion of this video. Participants completed surveys about their general, testicular, and total cancer knowledge before and after viewing the video. Although hearing men had higher pre-test scores than Deaf men, both Deaf and hearing men demonstrated significant increases in General, Testicular, and Total Cancer Knowledge scores after viewing the intervention video. Overall, results demonstrate the value of the video to Deaf and hearing men.     

A randomised comparison of microwave endometrial ablation with transcervical resection of the endometrium: follow up at a minimum of 10 years

Objective  To compare outcomes and further operations at a minimum of 10 years following microwave endometrial ablation (MEA^TM) or transcervical resection of the endometrium (TCRE).
Design  Follow up of a randomised controlled trial using postal questionnaires and operative databank review.
Setting  Gynaecology department of a large UK teaching hospital.
Main outcome measures  Women's satisfaction with treatment, menstrual symptoms, changes in health-related quality of life, and additional treatments received.
Results  One-hundred and eighty-nine of the original 263 women returned questionnaires (72%) after a minimum of 10 years post-treatment. Those totally or generally satisfied with treatment numbered 77/129 (60%) in the microwave arm and 70/134 (52%) in the resection arm, the difference is not statistically significant. Bleeding and pain scores were highly significantly reduced and similar following both MEA^TM and TCRE, achieving amenorrhoea rates of 83 and 88% respectively. The hysterectomy rate after 10 years was significantly different with 22 (17%) in the MEA^TM and 38 (28%) in the TCRE arm (95% CI: −0.21, −0.13).
Conclusions  Both techniques achieve significant and comparable improvements in menstrual symptoms, health-related quality of life and high rates of satisfaction. With the known operative advantages, lower costs and fewer hysterectomies, it is clear that MEA™ is a more effective and efficient treatment for heavy menstrual loss than TCRE.
