    BACKGROUND: Sexually transmitted infections (STIs), including Hepatitis B and C virus, are emerging public health risks in China, especially among men who have sex with men (MSM). This study aims to assess the magnitude and risks of STIs among Chinese MSM. METHODS: Chinese and English peer-reviewed articles were searched in five electronic databases from January 2000 to February 2013. Pooled prevalence estimates for each STI infection were calculated using meta-analysis. Infection risks of STIs in MSM, HIV-positive MSM and male sex workers (MSW) were obtained. This review followed the PRISMA guidelines and was registered in PROSPERO. RESULTS: Eighty-eight articles (11 in English and 77 in Chinese) investigating 35,203 MSM in 28 provinces were included in this review. The prevalence levels of STIs among MSM were 6.3% (95% CI: 3.5-11.0%) for chlamydia, 1.5% (0.7-2.9%) for genital wart, 1.9% (1.3-2.7%) for gonorrhoea, 8.9% (7.8-10.2%) for hepatitis B (HBV), 1.2% (1.0-1.6%) for hepatitis C (HCV), 66.3% (57.4-74.1%) for human papillomavirus (HPV), 10.6% (6.2-17.6%) for herpes simplex virus (HSV-2) and 4.3% (3.2-5.8%) for Ureaplasma urealyticum. HIV-positive MSM have consistently higher odds of all these infections than the broader MSM population. As a subgroup of MSM, MSW were 2.5 (1.4-4.7), 5.7 (2.7-12.3), and 2.2 (1.4-3.7) times more likely to be infected with chlamydia, gonorrhoea and HCV than the broader MSM population, respectively. CONCLUSION: Prevalence levels of STIs among MSW were significantly higher than the broader MSM population. Co-infection of HIV and STIs were prevalent among Chinese MSM. Integration of HIV and STIs healthcare and surveillance systems is essential in providing effective HIV/STIs preventive measures and treatments. TRIAL REGISTRATION: PROSPERO NO: CRD42013003721

    The effects of long-term total parenteral nutrition on gut mucosal immunity in children with short bowel syndrome: a systematic review

    Get PDF
    BACKGROUND: Short bowel syndrome (SBS) is defined as the malabsorptive state that often follows massive resection of the small intestine. Most cases originate in the newborn period and result from congenital anomalies. It is associated with a high morbidity, is potentially lethal and often requires months, sometimes years, in the hospital and home on total parenteral nutrition (TPN). Long-term survival without parenteral nutrition depends upon establishing enteral nutrition and the process of intestinal adaptation through which the remaining small bowel gradually increases its absorptive capacity. The purpose of this article is to perform a descriptive systematic review of the published articles on the effects of TPN on the intestinal immune system investigating whether long-term TPN induces bacterial translocation, decreases secretory immunoglobulin A (S-IgA), impairs intestinal immunity, and changes mucosal architecture in children with SBS. METHODS: The databases of OVID, such as MEDLINE and CINAHL, Cochran Library, and Evidence-Based Medicine were searched for articles published from 1990 to 2001. Search terms were total parenteral nutrition, children, bacterial translocation, small bowel syndrome, short gut syndrome, intestinal immunity, gut permeability, sepsis, hyperglycemia, immunonutrition, glutamine, enteral tube feeding, and systematic reviews. The goal was to include all clinical studies conducted in children directly addressing the effects of TPN on gut immunity. RESULTS: A total of 13 studies were identified. These 13 studies included a total of 414 infants and children between the ages approximately 4 months to 17 years old, and 16 healthy adults as controls; and they varied in design and were conducted in several disciplines. The results were integrated into common themes. Five themes were identified: 1) sepsis, 2) impaired immune functions: In vitro studies, 3) mortality, 4) villous atrophy, 5) duration of dependency on TPN after bowel resection. CONCLUSION: Based on this exhaustive literature review, there is no direct evidence suggesting that TPN promotes bacterial overgrowth, impairs neutrophil functions, inhibits blood's bactericidal effect, causes villous atrophy, or causes to death in human model. The hypothesis relating negative effects of TPN on gut immunity remains attractive, but unproven. Enteral nutrition is cheaper, but no safer than TPN. Based on the current evidence, TPN seems to be safe and a life saving solution

    Tracheostomy care and decannulation during the COVID-19 pandemic. A multidisciplinary clinical practice guideline.

    Get PDF
    PURPOSE: Traditional critical care dogma regarding the benefits of early tracheostomy during invasive ventilation has had to be revisited due to the risk of COVID-19 to patients and healthcare staff. Standard practises that have evolved to minimise the risks associated with tracheostomy must be comprehensively reviewed in light of the numerous potential episodes for aerosol generating procedures. We meet the urgent need for safe practise standards by presenting the experience of two major London teaching hospitals, and synthesise our findings into an evidence-based guideline for multidisciplinary care of the tracheostomy patient. METHODS: This is a narrative review presenting the extensive experience of over 120 patients with tracheostomy, with a pragmatic analysis of currently available evidence for safe tracheostomy care in COVID-19 patients. RESULTS: Tracheostomy care involves many potentially aerosol generating procedures which may pose a risk of viral transmission to staff and patients. We make a series of recommendations to ameliorate this risk through infection control strategies, equipment modification, and individualised decannulation protocols. In addition, we discuss the multidisciplinary collaboration that is absolutely fundamental to safe and effective practise. CONCLUSION: COVID-19 requires a radical rethink of many tenets of tracheostomy care, and controversy continues to exist regarding the optimal techniques to minimise risk to patients and healthcare workers. Safe practise requires a coordinated multidisciplinary team approach to infection control, weaning and decannulation, with integrated processes for continuous prospective data collection and audit

    A Social Identity Approach to Sport Psychology: Principles, Practice, and Prospects.

    Get PDF
    Drawing on social identity theory and self-categorization theory, we outline an approach to sport psychology that understands groups not simply as features of sporting contexts but rather as elements that can be, and often are, incorporated into a person's sense of self and, through this, become powerful determinants of their sport-related behavior. The underpinnings of this social identity approach are outlined, and four key lessons for sport that are indicative of the analytical and practical power of the approach are presented. These suggest that social identity is the basis for sports group (1) behavior, (2) formation and development, (3) support and stress appraisal, and (4) leadership. Building on recent developments within sport science, we outline an agenda for future research by identifying a range of topics to which the social identity approach could fruitfully contribute

    Prostate cancer is a highly heritable disease with large disparities in incidence rates across ancestry populations. We conducted a multiancestry meta-analysis of prostate cancer genome-wide association studies (107,247 cases and 127,006 controls) and identified 86 new genetic risk variants independently associated with prostate cancer risk, bringing the total to 269 known risk variants. The top genetic risk score (GRS) decile was associated with odds ratios that ranged from 5.06 (95% confidence interval (CI), 4.84-5.29) for men of European ancestry to 3.74 (95% CI, 3.36-4.17) for men of African ancestry. Men of African ancestry were estimated to have a mean GRS that was 2.18-times higher (95% CI, 2.14-2.22), and men of East Asian ancestry 0.73-times lower (95% CI, 0.71-0.76), than men of European ancestry. These findings support the role of germline variation contributing to population differences in prostate cancer risk, with the GRS offering an approach for personalized risk prediction

    OBJECTIVES: A cuffed tracheostomy tube facilitates prolonged mechanical ventilation and weaning but usually leads to prolonged voicelessness, which can be one of the most negative experiences of hospitalization. No randomized trials have examined the effects of targeted early communication intervention for the restoration of voice in ventilated tracheostomy patients in the ICU. DESIGN: A prospective randomized clinical trial. SETTING: The trial was conducted in the ICU of an urban tertiary level hospital. PATIENTS: Thirty adult participants enrolled, with 15 randomly allocated to the intervention and control groups. INTERVENTIONS: The early intervention group received early cuff deflation and insertion of an in-line speaking valve during mechanical ventilation. The control group received standard cuff deflation and a speaking valve during self-ventilation. A speech-language pathologist provided all treatments. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was time from tracheostomy insertion to phonation. Early intervention significantly hastened return to phonation (median difference = 11 d; hazard ratio = 3.66; 95% CI, 1.54-8.68) with no significant effect on duration of tracheostomy cannulation (hazard ratio = 1.40; 95% CI, 0.65-3.03), duration of mechanical ventilation in days from tracheostomy insertion (hazard ratio = 1.19; 95% CI, 0.58-2.51), length of stay in ICU (hazard ratio = 1.16; 95% CI, 0.54-2.52), or time to return to oral intake (hazard ratio = 2.35; 95% CI, 0.79-6.98). Adverse events were low and equal in both groups. There was no significant change in measures of quality of life. CONCLUSIONS: Focused early intervention for communication during mechanical ventilation allows the restoration of phonation significantly sooner than standard treatment, with no increase in complications in a small patient cohort. Although these results are favorable, further research is needed to determine whether the effects on any of the secondary outcomes are statistically significant and clinically important

    © 2019 Wiley Periodicals, Inc. Background: Technological advances in radiotherapy have allowed investigations into new methods to spare healthy tissue in those treated for head and neck cancer. This systematic review with meta-analysis demonstrates the effect that radiation has on swallowing. Methods: Selection and analysis of studies examining the effect of radiation to swallowing structures. A fixed effects meta-analysis calculated the pooled proportions for select outcomes of dysphagia, common across many studies. Results: The majority of the papers found a correlation between radiation dose to the swallowing structures and dysphagia, however a meta-analysis found the studies carried a significant degree of heterogeneity. The appraisal demonstrates the need for large-scale studies using a randomized design and instrumental dysphagia assessments. Conclusions: Radiation dose to dysphagia and aspiration structures is correlated with incidence of dysphagia and aspiration. The variables in this population contribute to the heterogeneity within and cross studies and future studies should consider controlling for this

    Quality of life improves with return of voice in tracheostomy patients in intensive care: An observational study.

    Full text link
    PURPOSE: To measure patient-reported change of mood, communication-related quality of life, and general health status with return of voice among mechanically ventilated tracheostomy patients admitted to the intensive care unit (ICU). MATERIALS AND METHODS: A prospective observational study in a tertiary ICU was conducted. Communication-related quality of life was measured daily using the Visual Analogue Self-Esteem Scale. General health status was measured weekly using the EuroQol-5D. RESULTS: Aspects of communication self-esteem that significantly improved with the return of voice were ability to be understood by others (P = .006) and cheerfulness (P = .04), both with a median difference from before to after return of voice of 1 on the 5-point scale. Return of voice was not associated with a significant improvement in confidence, sense of outgoingness, anger, sense of being trapped, optimism, or frustration. Reported general health status did not significantly improve. CONCLUSIONS: Return of voice was associated with significant improvement in patient reported self-esteem, particularly in being understood by others and in cheerfulness. Improved self-esteem may also improve quality of life; however, further research is needed to confirm this relationship. Early restoration of voice should be investigated as a way to improve the experience of ICU for tracheostomy patients

    Quality of life improves for tracheostomy patients with return of voice: A mixed methods evaluation of the patient experience across the care continuum

    Full text link
    © 2018 Elsevier Ltd Objectives: A tracheostomy tube can profoundly impact ability to communicate. The impact of this on patients’ self-esteem and quality of life in the care continuum from the intensive care unit to after decannulation has not been reported. Therefore, the aim was to investigate the patient-reported experience regarding change in communication function, communication-related self-esteem and quality of life. Research design: A mixed methods approach was utilised. Quantitative data were obtained using validated measures of self-esteem related to communication-related quality of life and general health. Data were measured before return of voice, within 48 hours of voice return and six months after tracheostomy decannulation. Qualitative data were collected through structured interviews six months after tracheostomy. Results: Seventeen participants completed the study. Four themes emerged from the interviews: It's hard communicating without a voice; What is happening to me?; A storm of dark emotions and More than a response…it's participating and recovering. Significant positive change occurred in six items of self-esteem related to communication from baseline to return of voice. Overall, positive changes in quality of life scores were observed. Conclusions: Voice loss with tracheostomy significantly affected participants’ abilities to effectively communicate their care and comfort needs. Restoration of voice occurred in conjunction with patient-reported improved mood, outlook and sense of recovery

    Early fiberoptic endoscopic evaluation of swallow in transoral robotic surgery: Description of swallow function and recovery in the acute postoperative period for oropharyngeal squamous cell carcinoma.

    BackgroundTransoral robotic surgery (TORS) is a minimally invasive approach for the treatment of oropharyngeal cancer. The effects on swallowing and speech need to be comprehensively evaluated to understand the associated morbidity.MethodsA prospective cohort of 21 patients was recruited to undergo pre-TORS and post-TORS swallowing and communication assessment. Fiberoptic endoscopic evaluation of swallowing (FEES) was used in the first postoperative week.ResultsSixteen participants (76.2%) had penetration-aspiration scores ≥3 or higher, seven (33.3%) aspirated on thin liquids, three (14.3%) did so silently. Prolonged recovery trajectory occurred for the majority of the cohort, particularly if TORS was followed by adjuvant radiotherapy. Swallowing and communication scores were significantly worse in base of tongue primary tumors and with advanced age.ConclusionEarly FEES demonstrates a significant decline in swallowing function, including increased secretion load, pharyngeal residue, laryngeal penetration, and aspiration. Silent aspiration occurred in 14% and thus highlights the necessity for instrumental assessment to ascertain aspiration risk
