This prospective cohort study was conducted to compare the accuracy of QuantiFERON®-TB (QFT) Gold In-Tube test and tuberculin skin test (TST) in diagnosing tuberculosis (TB) in predominantly bacille Calmette–Guerin-vaccinated children with a high incidence of malnutrition. The sensitivity of the QFT versus the TST was 69.6% versus 52.9% for WHO-defined TB, with specificity of 86% versus 78.3%, respectively. The concordance of the TST and QFT was 79% overall (κ = 0.430), 62.5% in those with WHO-defined TB and 85.7% in those without TB. Majority of the QFT+/TST − discordance was seen in children with TB, whereas majority of the TST+/QFT − discordance was seen in those without TB. The TST was more likely to be negative in children with moderate-to-severe malnutrition (P = 0.003) compared to the QFT, which was more likely to be positive in younger children. The significantly better performance of the QFT in malnourished children and those at younger ages supports its use for TB diagnosis in these subpopulations.  相似文献

Objective

The advantage of arteriovenous fistulas (AVFs) in older patients requiring dialysis is controversial. We reviewed our vascular access experience in patients ≥70 years of age (older group) compared with younger patients.

Methods

We analyzed consecutive patients who underwent access surgery between 2013 and 2016. Primary success (PS) and primary patency (PP) data were analyzed between the older and younger groups before and after propensity score matching of the patients' characteristics and access composition. PS was defined as the achievement of access function that was amenable to two sessions of successful cannulation without early occlusion or maturation failure requiring revision. PP was defined as the time with uninterrupted patency without intervention.

Results

A total of 594 consecutive accesses were created among 563 patients, of whom 119 were allocated into each group after propensity score matching. In the whole cohort, 193 accesses (32.5%) were performed in older patients. AVFs were performed in 130 (67.4%) older patients and 293 (73.1%) younger patients. Regarding AVFs, the PS rate (83.6% in the older group vs 94.3% in the younger group; P = .001) and the overall PP at 6 and 12 months (73.1% and 57.1%, respectively, in the older group vs 86.7% and 77.7%, respectively, in the younger group; P = .009) were lower in the older group than in the younger group. However, no differences were found in the PS and PP rates for arteriovenous grafts between groups. Regarding the AVF location, the PS rate for forearm AVFs was significantly lower in the older group than in the younger group (76% vs 93%; P < .001); however, the PS rate of the upper arm was not different between the groups (94% vs 97%; P = .425). In the patients with PS, the PP rate of AVFs was similar between the two groups. In the older group with forearm AVFs, the median diameter of the radial artery was larger in the patients with PS than in the patients without PS (2.20 mm with PS vs 2.00 mm without PS; P = .008). The propensity score matching results demonstrated similar trends for the whole cohort, with lower PS (P = .042) and PP rates (P = .023) for AVF in the older group.

Conclusions

The outcomes after AVF were poorer in the older group than in the younger group, which was primarily due to unsatisfactory outcomes in patients with forearm AVFs. Thus, stricter criteria, especially regarding the radial artery diameter, should be applied for forearm AVFs in older patients, and additional research is necessary to delineate the risk factors for primary failure.  相似文献

目的比较腹腔镜联合支架与开腹联合支架治疗左半结肠癌伴梗阻患者的疗效。方法选取2014年1月~2017年1月40例左半结肠癌伴梗阻患者,将其分为观察组和对照组,每组20例。观察组患者采用腹腔镜联合支架治疗,对照组患者采用开腹联合支架治疗。对比分析两组的术后情况、应激反应情况及细胞免疫功能变化情况。结果与对照组相比,观察组术后排气时间短,抗生素使用时间短,术后住院时间短,住院费用高,术后72 h CRP水平低,术后72 h CD3~+、CD4~+/CD8~+水平高,差异均有统计学意义(P0.05)。与对照组相比,观察组术后并发症发生率低,但差异无统计学意义。结论相比开腹联合支架治疗,腹腔镜联合支架治疗左半结肠癌伴梗阻患者,术后消化道功能恢复快,应激反应较轻,对细胞免疫功能影响较小,住院时间短,近期疗效优势明显。  相似文献

Background

Testing for high-risk human papilloma virus (HR-HPV) is an effective approach to the prevention of cervical cancer. This study in the Atsinanana area of Madagascar aimed to compare the management of women screened by visual inspection after coloration with acetic acid (VIA) and the management of women screened by HPV with VIA as a triage test.

Method

During the last two screening campaigns, the first patients (between 28 and 120 women par center) were sampled using a dry swab, just before the acetic acid application, to test 14 genotypes of HR-HPV using Roche Diagnostics Cobas® Test. We compared current management practices based on primary VIA to those that would have been implemented if the clinician had followed the recommendations of the World Health Organization for HPV-based primary screening. We used a regression Poisson model with random effect and robust variance.

Results

Among the 250 screened-women, 28 (11.2%) had acidophilic lesions of the uterine cervix or suspected lesions of invasive cancer (IVA +). The HPV test was positive in 62 cases (24.8%). The HPV-based screening strategy would have reduced by 52% the number of women needing thermo-coagulation treatment: 24 women (9.6%) with primary VIA-based screening vs. 13 women (5.2%) with primary HPV-based screening; RR: 0.52 and 95%CI: 0.27–1.02. The diagnosis of severe dysplastic lesion or invasive cancer would not have changed.

Conclusion

Primary HPV-based screening is a strategy that could be useful for low-resource countries like Madagascar. It would reduce the rate of false positives and unnecessary treatments compared to the current strategy based on primary IVA. The questions of the feasibility and cost-benefit of this strategy should be further explored.  相似文献

Objective: The present study was performed to assess nutritional status and its relationship with clinical outcomes in elderly stroke patients.

Method: In this cross-sectional study, 253 stroke patients were studied. Mini Nutritional Assessment (MNA) was used to assign patients to three groups: malnourished, at risk of malnutrition, and well nourished. Northwestern Dysphagia Patient Check Sheet was administered to all patients. Anthropometric measures, including body mass index (BMI), calf circumferences (CC), mid-arm circumferences (MAC), and triceps skinfold thickness were brought out. In addition, National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), and biochemical tests were performed.

Results: Of 253 patients, 34.4% were malnourished, 42.3% were at risk of malnutrition, and 23.3% were well nourished. The malnourished patients had significantly lower BMI, CC, and MAC (p?<?0.05). The levels of albumin and high-sensitivity C-reactive protein were significantly different among the groups (p?<?0.001). The admission and 3-month follow-up mRS scores, as well as dysphagia, were significantly higher in the malnourished patients and those at risk of malnutrition (p?<?0.001). In addition, mRS scores at admission and 3-month follow-up scores, as well as the length of hospital stay (LOS), were significantly correlated with MNA score, dysphagia, BMI, CC, MAC, albumin, and high-sensitivity C-reactive protein (p?<?0.05). Significant unadjusted associations were observed among MNA scores, BMI, CC, MAC, dysphagia scores, NIHSS scores, length of hospital stay (LOS), albumin, hs-C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR) with a poor outcome. With a multivariate logistic regression analysis, NIHSS scores and MNA scores remained significantly associated with the poor outcome in patients with ischemic stroke.

Conclusions: The findings of the present study underline the importance of nutritional status in elderly stroke patients.  相似文献
