OBJECTIVE: To determine if screening family members of patients with acute brucellosis will enhance the detection rate of brucellosis and also to determine the relationship between symptoms and brucella serology. MATERIALS AND METHODS: Family members from patients with acute brucellosis were interviewed and serologically screened. All seropositive family members were clinically and serologically followed for six months. RESULTS: Twenty-five acute brucellosis patients and their 178 family members were enrolled from January 2001 to February 2002. Of the 178 family members, 40 (23%) manifested various symptoms, 138 (77%) were asymptomatic, with an overall seroprevalence rate of 34 (19%). The rate of seropositivity among the symptomatic family members was 23 (58%) and for the asymptomatic was 11 (8%) (P<0.001). The majority of the symptomatic family members (13 (57%)) had a high Brucella titer in comparison to one (9%) of the asymptomatic group (P<0.001). Acute brucellosis was diagnosed and treated in 18 (78%) of the symptomatic seropositive family members and in four (36%), of the asymptomatic seropositive family members with an acute brucellosis prevalence rate of 22 (12%). All family members with acute infection recovered without sequelae; one patient relapsed (5%). CONCLUSION: Symptomatic family members are more likely to be seropositive with a high titer in comparison to the asymptomatic members. 相似文献

Background
Chemotherapy‐induced peripheral neuropathic pain (CIPNP) is a serious dose‐limiting neurotoxic effect of cancer drug treatment. The underlying mechanism(s) of this debilitating condition, which lacks effective drug treatment, is incompletely understood. However, neural–immune interactions, involving increased expression and release of cytokines, are believed to be involved. Here, we examined, in the paclitaxel rat model of CIPNP, whether plasma levels of 24 cytokines/chemokines change after paclitaxel treatment, and whether blocking of signalling of some of those cytokines would reverse/attenuate behavioural signs of CIPNP.Methods
To achieve these objectives luminex, pharmacological and behavioural experiments were performed on male Wistar rats (250–300 g) 31 days after the last injection of paclitaxel (1 mg/kg, i.p. on four alternate days) as well as on control (vehicle‐treated) rats.Results
Compared with control rats, plasma levels of IL‐1α, IL‐1β, IL‐6, TNF‐α, INF‐γ and MCP‐1 were significantly upregulated in paclitaxel‐treated rats. Blocking of TNF‐α signalling with etanercept (2 mg/kg, i.p.) or IL‐1β with IL‐1 receptor antagonist (IL‐1ra; 3 mg/kg, i.p.), significantly attenuated established mechanical and cold hypersensitivity as well as spontaneous pain behaviour (spontaneous foot lifting) 24 and 48 h postdrug treatment. Pharmacological blockade of MCP‐1/CCL2 signalling with a highly selective CCR2 receptor antagonist (S504393, 5 mg/kg, i.p.) also significantly reduced evoked, but not spontaneous, pain behaviours of CIPNP in paclitaxel‐treated rats at the same time points.Conclusions
The findings support the notion that cytokines/chemokines, particularly TNF‐α, IL‐1 and MCP‐1, are involved in the pathophysiology of CIPNP and suggest that strategies that target their inhibition may be effective in treating CIPNP.Significance
This study demonstrates that paclitaxel‐treated rats exhibit, in addition to indices of mechanical and cold hypersensitivity, a behavioural sign of spontaneous pain, the principal compliant of patients with neuropathic pain. This was accompanied by upregulation in plasma levels of key cytokines/chemokines (IL‐1α, IL‐1β, IL‐6, TNF‐α, INF‐γ and MCP‐1) 31 days post‐treatment. However, it is noteworthy that cytokine release, rather than nerve injury per se, may be causative of NP in this model of CIPNP. Nevertheless, our findings that pharmacological blockade of TNF‐α, IL‐1β and MCP‐1 attenuated both evoked and spontaneous pain suggest that strategies that target inhibition of these cytokines may be effective in treating CIPNP. 相似文献55.

Background
Suboptimal adherence to medication increases mortality and morbidity; individually tailored supportive interventions can improve patients’ adherence to their medication regimens.Aims
The study aims to use a pilot randomised controlled trial (RCT) to test the hypothesis that a theory-based, nurse-led, multi-faceted intervention comprising motivational interviewing techniques and text message reminders in addition to standard care will better promote medication adherence in cardiac patients compared to standard care alone. The pilot study will assess self-reported adherence or non-adherence to cardiovascular medication in patients referred to a cardiac rehabilitation program following hospital admission for an acute cardiac event and test the feasibility of the intervention. The study will examine the role of individual, behavioural and environmental factors in predicting medication non-adherence in patients with CVD.Methods
This is a mixed- methods study including a nested pilot RCT. Twenty-eight cardiac patients will be recruited; an estimated sample of nine patients in each group will be required for the pilot RCT with 80% power to detect a moderate effect size at 5% significance, and assuming 50% loss to follow-up over the six month intervention. Participants will complete a paper-based survey (Phase one), followed by a brief semi-structured interview (Phase two) to identify their level of adherence to medication and determine factors predictive of non-adherence. Participants identified as ‘non-adherent’ will be eligible for the pilot randomised trial, where they will be randomly allocated to receive either the motivational interview plus text message reminders and standard care, or standard care alone.Discussion
Nurse-led multi-faceted interventions have the potential to enhance adherence to cardiac medications. The results of this study may have relevance for cardiac patients in other settings, and for long-term medication users with other chronic diseases. 相似文献56.

We aimed to establish the local prevalence of musculoskeletal pain among faculty members in Saudi Arabia and describe the patient''s risk factors and preventive measures that may reduce its burden.An observational, quantitative, cross-sectional study was carried out to evaluate the prevalence of musculoskeletal pain and its risk factors among male faculty members in the College of Medicine and Dentistry, using a designed questionnaire based on the Standardized Nordic Musculoskeletal Questionnaire. Chi-square testing at a significance level of P < .05, was used for comparative analysis. SPSS version 26 was used for all analyses.Ninety responders participated in the survey analysis. The prevalence of musculoskeletal pain among faculty members was 77.8%, and the most common site of musculoskeletal pain occurred at two different sites of the three (low back, neck, and shoulder), with a prevalence of 38.9%. As for risk factors of musculoskeletal pain, only age group showed a significant correlation with the site of musculoskeletal pain (P = .024), where patients in the younger age group (25–35 years old) were at higher risk of lower back pain, while participants in the older age group (36 to 44 years old and 45 years or older) were at higher risk of musculoskeletal pain in two different sites.Musculoskeletal pain affects more than two-thirds of faculty members. In particular, low back pain is a common problem among faculty members. Age is a significant risk factor for the occurrence of musculoskeletal pain, with more than one site involvement in older age. 相似文献

The present study investigates a process for the selective production of hydrogen from the catalytic decomposition of formic acid in the presence of iridium and iridium–palladium nanoparticles under various conditions. It was found that a loading of 1 wt.% of 2% palladium in the presence of 1% iridium over activated charcoal led to a 43% conversion of formic acid to hydrogen at room temperature after 4 h. Increasing the temperature to 60 °C led to further decomposition and an improvement in conversion yield to 63%. Dilution of formic acid from 0.5 to 0.2 M improved the decomposition, reaching conversion to 81%. The reported process could potentially be used in commercial applications. 相似文献

Purpose: The purpose of this study is to cross-culturally adapt the Knee Outcome Survey-Activities of Daily Living Scale into Arabic and to assess its psychometric properties (internal consistency, reliability, validity, and responsiveness) in patients with knee disorders.Methods: The cross-cultural adaptation process for the Knee Outcome Survey-Activities of Daily Living Scale into Arabic was performed consistent with the published guidelines. The psychometric properties of this Arabic version were then evaluated. Participants completed this version three times: at baseline, 2–4 days later, and 4?weeks later. Correlations between the Arabic version of Knee Outcome Survey-Activities of Daily Living Scale and the Arabic version of the Short Form-36 Health Survey, Get Up and Go, and Ascending/Descending stairs tests were evaluated.Results: Linguistic and cultural issues were addressed. The Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale demonstrated excellent internal consistency (Cronbach’s alpha?=?0.97) and excellent test–retest reliability (intraclass correlation coefficient?=?0.97). Construct validity of the Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale with the Arabic version of Short Form-36 Health Survey subscales ranged from r?=?0.28 to 0.53, p?0.001. Criterion validity with the Get Up and Go and Ascending/Descending stairs tests ranged from r?=??0.47 to ?0.60, p?0.01. This Arabic version was able to detect changes 4?weeks later (effect size?=?1.12 and minimum clinically important difference?=?14 points).Conclusions: The Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale is a reliable, valid and responsive measure for assessing knee-related symptoms and functional limitations
- Implications for rehabilitation
The Knee Outcome Survey-Activities of Daily Living Scale-Arabic is a reliable, valid and responsive measure for assessing knee-related functional limitations.
This Arabic version can be used in clinical practice and for research purposes to assess symptoms and functional limitations in Arabic-speaking patients with knee disorders.
This scale is responsive to track therapeutic outcome of Arabic-speaking patients with knee disorders.
