Fungi are amongst the bioaerosols of most importance, as indicated by the growing interest in this field of research. The aim was to characterize the exposure to fungal burden in podiatry clinics using culture-based and molecular methods. Methods: Airborne fungi were collected using an impaction air sampler and surface samples were also performed. Fourteen air samples were collected for direct detection of fungal DNA from filamentous fungi and dermatophytes. Overall, 63.6 % of the evening samples and 46 % of the morning samples surpassed the threshold values (150 CFU/m3). Molecular detection, by real time PCR, of the target fungal species/strains (Aspergillus and Stachybotrys species) was negative for all samples collected. Trichophyton rubrum was detected by PCR analysis in one DNA sample collected on day six. Results suggest the use of both culture-based and molecular methodologies are desirable for a complete evaluation of fungal burden in this particular health care setting.  相似文献

Purpose

The purpose was to determine whether Appalachian residence alone or in combination with violence was linked to poorer quality of life (QOL).

Methods

Women recently diagnosed and included in either the Kentucky or North Carolina Cancer Registries were interviewed by phone between 2009 and 2015 (n?=?3320; mean age?=?56.74). Response rates were similar by state (40.1 in Kentucky and 40.9% in North Carolina). Appalachian (N?=?990) versus non-Appalachian residents (N?=?2330) were hypothesized to have poorer QOL defined as (a) lower Functional Assessment of Cancer Therapy—General (FACT-G) scores and (b) more symptoms of depression, stress, or comorbid physical conditions. Lifetime intimate partner or sexual violence was first investigated as a moderator then mediator of regional differences. Multiple analyses of covariance (MANCOVA) models were used.

Results

Violence modified the effect of Appalachian residence on poorer QOL outcomes; FACT-G total scores (p?=?.02) were lowest for women living in Appalachia who had additionally experienced violence. Socioeconomic indicators appeared to mediate or explain differences in QOL outcomes by Appalachian residence such that when adjusting for income, education and insurance, Appalachian residence remained associated only with poorer physical QOL outcomes (p?<?.05).

Conclusions

While violence rates did not differ by residence, the combined effect of living in Appalachia and experiencing violence resulted in significantly greater impact on poorer QOL among women recently diagnosed with cancer. Clinical consideration of patients’ residence, socioeconomic status and violence experienced may help identify and mitigate the longer-term impact of these identifiable factors associated with poorer QOL.

Purpose

To conduct a systematic literature review of the reliability, construct validity, and responsiveness of the SF-36® Health Survey (SF-36) in patients with ulcerative colitis (UC).

Methods

We performed a systematic search of electronic medical databases to identify published peer-reviewed studies which reported scores from the eight scales and/or two summary measures of the SF-36 collected from adult patients with UC. Study findings relevant to reliability, construct validity, and responsiveness were reviewed.

Results

Data were extracted and summarized from 43 articles meeting inclusion criteria. Convergent validity was supported by findings that 83% (197/236) of correlations between SF-36 scales and measures of disease symptoms, disease activity, and functioning exceeded the prespecified threshold (r ≥ |0.40|). Known-groups validity was supported by findings of clinically meaningful differences in SF-36 scores between subgroups of patients when classified by disease activity (i.e., active versus inactive), symptom status, and comorbidity status. Responsiveness was supported by findings of clinically meaningful changes in SF-36 scores following treatment in non-comparative trials, and by meaningfully larger improvements in SF-36 scores in treatment arms relative to controls in randomized controlled trials. The sole study of SF-36 reliability found evidence supporting internal consistency (Cronbach’s α ≥ 0.70) for all SF-36 scales and test–retest reliability (intraclass correlation coefficient ≥0.70) for six of eight scales.

Conclusions

Evidence from this systematic literature review indicates that the SF-36 is reliable, valid, and responsive when used with UC patients, supporting the inclusion of the SF-36 as an endpoint in clinical trials for this patient population.

To meet increasing demand for home care, the role of personal support workers (PSWs) is shifting from providing primarily personal and supportive care to include care activities previously provided by regulated health professionals (RHPs). Much of the research examining this shift focuses on specialty programmes, with few studies investigating the daily care being provided by PSWs, frequency of care activities being provided by PSWs, and characteristics of the population receiving more complex tasks. Between January and April 2015, a review of 517 home‐care service user charts was undertaken in Ontario, Canada, to: (1) describe the range of tasks being performed by PSWs in home care, (2) identify tasks transferred by RHPs to PSWs, and (3) examine characteristics of service users receiving transferred care. Findings indicate that normally, PSWs provide personal and supportive care commensurate with their training. However, in approximately one quarter of care plans reviewed, PSWs also completed more complex care activities transferred to them by RHPs. Service users receiving transferred care were older and had higher levels of cognitive and functional impairment. Although there is potential for the expansion of home‐care services through increased utilisation of PSWs, healthcare leadership must ensure that the right provider is being utilised at the right time and in the right place to ensure safe and effective quality care. Thus, several actions are recommended: PSW core competencies be clearly articulated, processes used to transfer care activities from RHPs to PSWs be standardised and a team‐based approach to the delivery of home‐care services be considered. Utilisation of a team‐based model can help establish positive relationships among home‐care providers, provide increased support for PSWs, allow for easier scheduling of initial training and ensure regular reassessments of PSW competence among PSWs providing added skills.  相似文献

ABSTRACT

In this article, we examine methamphetamine (meth) use initiation as influenced by Latinas’ social positions within institutions (e.g., family and economy). We conducted ethnographic fieldwork in five women’s residential substance use treatment facilities in Los Angeles County with women who considered meth to be their primary drug of choice. Using an urban ethnographic framing, we demonstrate the effects of low-income young Latinas’ spatial- and social-context rendered vulnerability to abuse and neglect, and the resulting emotional distress, on meth use initiation. When considering pathways to substance use intervention for vulnerable Latina girls and women, clinicians, researchers, and policy makers need to understand substance use pathways as dynamic processes to cope with psychosocial stress while living in communities with easy access to illicit substances such as methamphetamine.  相似文献

Objectives Breastfeeding has short- and long-term health benefits for children and mothers, but US breastfeeding rates are suboptimal. Exposure to violence may contribute to these low rates, which vary by race/ethnicity. We studied: (1) whether patterns of violence exposure differ by race/ethnicity and (2) whether these patterns are associated with breastfeeding outcomes. Methods We conducted a secondary analysis of data drawn from self-report surveys completed by a convenience sample of low-income postpartum women (n?=?760) in upstate New York. Latent class analysis was used to identify groups of women with similar responses to seven violence measures, including childhood physical and/or sexual violence, experience of partner violence during or just after pregnancy (physical, emotional, verbal), and neighborhood violence (perceived or by ZIP code). Logistic regression and survival analysis were utilized to determine if classes were associated with breastfeeding initiation, duration, and exclusivity, controlling for demographics. Results Exposure to at least one form of violence was high in this sample (87%). We identified 4 classes defined by violence exposure (combining current and historical exposures). Violence exposure patterns differed between racial/ethnic groups, but patterns were inconsistently associated with breastfeeding plans or outcomes. For White women, history of violence exposure increased the likelihood of earlier breastfeeding cessation. By contrast, among Black women, history of violence exposure increased the likelihood of having a breastfeeding plan and initiating breastfeeding. Conclusions for Practice Some differences between violence exposure classes are likely due to the correlation between race/ethnicity and socioeconomic status in the community studied. Additional studies are warranted to better understand how exposure to violence is related to breastfeeding and how best to support women making decisions about intention, initiation, and duration of breastfeeding.  相似文献
