Objective

To assess the impact of providing integrated psycho-socio-economic support to drug resistant tuberculosis (DRTB) patients on the treatment outcome under programmatic conditions.

Study design

Retrospective cohort study.

Setting

An urban district TB centre in India under the Revised National Tuberculosis Control Programme.

Participants

A cohort of 123 patients who started DRTB treatment between June 2010 and May 2013.

Methods

Patients started on treatment for DRTB between June 2010 and May 2013 who were provided with the integrated support package for at least 3 months formed the supported group while the other patients of the cohort formed the non-supported group. The treatment outcomes and sputum culture conversion rates were compared between the two groups.

Results

The supported group consisted of 60 patients and the non-supported group of 63 patients. The treatment success rate was found to be significantly higher in the supported group (65% vs 46.03%; p = 0.0349). Support duration was significantly associated with lower incidence of death [HR 0.876, 95% CI 0.811–0.947; p = 0.0009] and loss to follow up [OR: 0.752, 95% CI 0.597–0.873; p = 0.0023]. The treatment failure rate was higher in the supported group (16.66% vs 4.76%) with 60% of the failures in the supported group occurring after 24 months of compliant treatment. There was no significant association found between support duration and treatment failure or sputum culture conversion.

Conclusion

Integrated support seems to significantly increase the treatment success rate and improve survival and treatment adherence of DRTB patients. However, early diagnosis and effective pharmacotherapy are crucial for reducing treatment failures.  相似文献

Introduction

Conservative Management (CM) has become a therapeutic option in Advanced Chronic Kidney Disease in the elderly. However, there is a lack of evidence about prognosis of these patients in terms of survival and health related quality of life (HRQoL).

Objective

Establish predictive variables associated with mortality and analyse HRQoL in CM patients.

Patients and methods

Prospective cohort study. An assessment of renal function parameters and a comprehensive geriatric assessment were made, including: analysis of comorbidity, functional, cognitive, fragility, nutritional, social and HRQoL status.

Results

82 patients with a mean age of 84 years and significant pluripathology were studied: 56% had history of vascular event and Charlson > 8. The mortality rate was 23/1,000 patients per month, with a homogeneous mortality rate after 6 months.Survival differed significantly depending on whether they presented with a previous vascular event (36.7 vs. 14.8; p = 0.028), Charlson score ≥ 10 (42 vs. 17; p = 0.002), functional status (48.4 vs. 19; p = 0.002) and fragility (27 vs. 10; p = 0.05).Mortality predictors included eGFR and proteinuria, the presence of previous vascular events, Charlson comorbidity score, malnutrition-inflammation parameters (albumin and MNA score), degree of dependency, physical HRQoL and increase of PTH level. The presence of previous vascular event, comorbidity, decreased albumin and elevated PTH were independent predictors of mortality. HRQoL remained stable over time and no significant worsening occurred during treatment.

Conclusions

Having knowledge of the factors associated with mortality and HRQoL assessment can be a useful tool to helping decision making during CM. Previous vascular events, comorbidity, decreased albumin and increased PTH were independent predictors of mortality.  相似文献

Background

Men who have sex with men (MSM) account for the highest prevalence of HIV in Brazil. HIV testing allows to implement preventive measures, reduces transmission, morbidity, and mortality.

Methods

We conducted a cross-sectional study to evaluate HIV testing during lifetime, factors associated with the decision to test, knowledge about HIV transmission, and use of condoms between MSM from the city of Natal, northeast Brazil.

Results

Out of 99 participants, 62.6% had been tested for HIV during lifetime, 46.2% in the last year. The most frequent reported reason to be tested for HIV infection was curiosity (35.5%). Correct knowledge about HIV was observed in only 9.2% of participants. In multivariate analysis, age (PR 0.95; 95%CI, 0.91–0.99; p = 0.041) and previous syphilis test (PR 4.21; 95%CI, 1.52–11.70; p = 0.006) were associated with HIV testing.

Conclusions

The frequency of HIV testing among MSM from Natal is rather low, especially in younger MSM, and knowledge about HIV transmission is inappropriate.  相似文献

Introduction and objectives

The reproducibility of the adverse reaction increases the suggestiveness of a history of food allergy. However, the positive predictive value (PPV) of multiple adverse reaction episodes for the diagnosis of IgE-mediated food allergy is not known. This evaluation was the objective of our study.

Patients and methods

We retrospectively studied 180 children with a history of non-anaphylactic adverse reactions after the ingestion of a food. All children had the prick test positive for the offending food and performed the oral food challenge (OFC) within 12 months after the last adverse reaction episode (ARE). We have evaluated whether increasing the number of ARE increased the probability that the OFC would be positive (failed).

Results

93 patients (52%) presented one ARE, 49 (27%) presented two ARE, 24 (13%) presented three ARE, 14 (8%) patients presented  four ARE. The OFC was positive in 94/180 (52%). The outcome of the OFC was found to be positively correlated with the number of ARE (OR = 1.56; 95% CI = 1.16–2.09; p = 0.003). A PPV = 100% was observed with a number of ARE  five.

Conclusions

The number of ARE is an important predictor of the diagnosis of food allergy, although less than we would have imagined. The number of ARE could be used to increase the predictability of the diagnostic tests currently in use, to define clinical prediction rules alternative to OFC and easy to use in clinical practice.  相似文献

Background

Investigating the survival of tuberculosis (TB) patients is one of the main parts of the TB control program. It can be related to many factors. This study aimed to estimate the survival experience and its associated factors among these patients.

Methodology

All TB patients detected during March 2005 to 31 September 2014 were entered into this prospective cohort. Each patient was investigated from the diagnosis date and followed until the last available information during treatment. Data analysis was performed using Kaplan Meier and multivariate Cox regression models.

Results

The survival experience of 2493 TB patients was investigated 73.7% of which were pulmonary type. Mean and median survival time were 6.5 and 6.2 months respectively. The incidence rate of death among patients during the treatment courses was 0.99 (95% confidence interval: 0.84–1.1) per 100 person-months. Controlling the confounders, the incidence (95% confidence interval) of death was significantly higher among men (HR = 1.8; 1.2–2.6), diabetic patients (HR = 1.7; 1.2–2.6), cancerous patients (HR = 4.8; 2.6–8.8) and HIV positive patients (HR = 22.1; 7.3–66.4).

Conclusion

This study showed that male gender, TB/HIV co-infection and concurrent development of TB and cancer were determinant factors of death during the treatment period of TB.  相似文献

Objective

To describe the management and evolution of high risk of death pulmonary embolism associated with right heart thrombi.

Material and methods

We conducted a prospective cohort survey over a 54 month-period, from March 1st, 2012 to September 30th 2015. Were included all patients with pulmonary embolism and having high or intermediate-high risk of death. Patients were divided into two groups according to whether cardiac Doppler-echography found a thrombus in the right chambers or not (ICT+ vs. ICT?). The survival curves for the patients were obtained using the software STATA.

Results

The prevalence of pulmonary embolism associated with right heart thrombi was 4% in our study. Thrombi were mobile, straight localization in all cases. The ICT + group was characterized by a significantly higher proportion of congestive heart and chronic lung disease. The proportion of patients’ thrombolysis was significantly higher in the ICT-group. In the ICT + group, thrombolysis significantly reduced mortality giving a 30-day survival of 80% against 20% among patients receiving only heparin.

Conclusion

Pulmonary embolism associated with right heart thrombi including the atrium are not exceptional. These patients are at high risk of early death. Thrombolysis is significantly improving the mortality of pulmonary embolism associated with right-sided heart thrombi.  相似文献

Introduction

Upper gastroscopy in patients with cirrhosis often reveals non-specific lesions, which are usually oriented as portal hypertensive gastropathy (PHG). However, the diagnosis of PHG can be difficult, both from an endoscopic and histological point of view. The study of CD34 expression, which enhances the endothelial cells of the microvasculature, could help the differential diagnosis. The objectives of this study were to evaluate the correlation between endoscopy and histology in the diagnosis of PHG and to assess the utility of CD34 in the diagnosis of PHG.

Material and methods

The results of immunostaining with CD34 gastric fundus biopsies from 100 cirrhotic patients and 20 controls were compared with the endoscopic images.

Results

The correlation between the histology and the endoscopic diagnosis of PHG was very low (kappa = 0.15). In addition, the measurement of the diameter of the gastric vessels enhanced by the use of immunohistochemical staining (CD34) did not show good correlation with the endoscopic diagnosis (p = .26) and did not provide relevant information for the histological diagnosis of PHG either.

Discussion

The correlation between histology and endoscopy is low for the diagnosis of PHG. The use of immunostaining for CD34 does not seem to improve the diagnostic yield of the histological study.  相似文献

Introduction

Polymyalgia rheumatica (PMR) can be associated with distal swelling indicating an associated RS3PE syndrome. We report a case of PMR associated with oedema of the lower limbs, which resolved rapidly under glucocorticoid therapy.

Case report

A 85-year-old woman presented with a 4 month history of PMR responding to the 2012 EULAR/ACR classification criteria. Examination of the lower limbs revealed pitting oedema bilaterally up to the knees, with mild erythema and warmth. Hypoalbuminemia (30 g/L) was present. There was no cardiac, renal or hepatic cause to explain leg swelling. FDG-PET/CT demonstrated increased metabolism in the periarticular area of shoulders and hips. There was no sign of aortitis or neoplasia. Under treatment with prednisone 10 mg/day leg swelling disappeared concomitantly to a weight loss of 8 kg within 8 days.

Conclusion

This case, the first to report leg swelling of inflammatory origin in the context of PMR, could indicate an increased vascular permeability caused by inflammation in the elderly.  相似文献

Objective

To investigate the relations of circulating adhesion molecule vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) with carotid artery elasticity in patients with impaired glucose regulation (IGR).

Methods

A total of 208 subjects were enrolled from January 2013 to March 2014. One hundred forty-eight were IGR patients, and 60 had normal glucose tolerance (NGT). Carotid intima-media thickness (IMT), carotid artery pressure-strain elasticity coefficient (Eρ), stiffness (β), arterial compliance (AC), and pulse wave velocity (PWVβ), as well as blood pressure, body mass index, blood glucose, blood lipids, insulin resistance index, VCAM-1, and ICAM-1 were measured and compared between IGR and NGT patients.

Results

Eρ, β and PWVβ were significantly higher in the IGR group than in the NGT group (P < 0.05), but the IMT showed no significant difference (P > 0.05). VCAM-1 and ICAM-1 were significantly higher in the IGR group than in the NGT group (P < 0.05). VCAM-1 and ICAM-1 were positively correlated with Eρ, β, and PWVβ and negatively correlated with AC in IGR patients.

Conclusions

Changes in carotid artery elasticity and endothelial dysfunction are found in patients with IGR. Early comprehensive intervention should be performed in such IGR populations.  相似文献

Objectives

Multinodular goiter is a common disorder, found in 5% of the general population. If only one thyroid lobe is affected, hemithyroidectomy may be preferred to total thyroidectomy, to limit the risk of complications and avoid hormone replacement therapy, but incurs a risk of subsequent completion thyroidectomy. The aim of the present study is to determine whether the arguments in favor of hemithyroidectomy are justified and whether it still provides real benefit.

Methods

A retrospective observational study based on prospective data included all patients who underwent surgery for goiter or nodule in our center between September 2010 and September 2014. Rates of hormone replacement 6 months after hemithyroidectomy, postoperative complications and completion thyroidectomy during the postoperative year due to the discovery of carcinoma were analyzed.

Results

Four hundred and ninety-three patients were studied: 335 with total thyroidectomy and158 with hemithyroidey. The rate of hormone replacement 6 months after hemithyroidectomy was 84.4%. The rate of definitive hypocalcemia was 6.3% in total thyroidectomy and zero in hemithyroidectomy (P < 0.05). There was no significant difference between groups in terms of recurrent laryngeal nerve palsy (1.8% versus 1.9%; P = 1) or hematoma (1.2% versus 3.5%; P = 0.15). A total of 11.3% of hemithyroidectomies required completion due to discovery of carcinoma (mean interval between surgeries 3.58 ± 2.5 months).

Conclusions

This study suggests that hemithyroidectomy does not in fact avoid the risk of hormone replacement and places the patient at risk of completion thyroidectomy. However, it does avoid a 6% rate of hypocalcemia. We would recommend hemithyroidectomy only in case of single toxic or euthyroid nodule with healthy contralateral lobe and/or refusal of hormone replacement by the patient.  相似文献

Introduction and Objectives

Asthma is a complex genetic disorder. Several genes have been found associated with asthma. The cystic fibrosis transmembrane conductance regulator (CFTR) gene is one of them. The aim of this study was to perform a comparative analysis of the genotype and allele frequency distributions of the biallelic marker M470V within the CFTR gene on mutant and wide chromosomes.

Patients and methods

The molecular approach consists in the genotyping of the M470V marker by the PCR-RFLP technique in 105 asthmatic patients, aged between four months and 17 years, and 105 healthy subjects.

Results

We found a significant difference in the genotype frequencies between the two studied groups (χ2 = 9.855, P = 0.007). The V/V genotype was over represented in the asthmatic group as compared to the controls (32.38% vs. 16.19%). Whereas, the M/V genotype is more frequent in healthy subjects (40.95% vs. 28.71%). We also noted a significant difference in allelic distribution of M470V with associated diseases (χ2 = 9.610, P = 0.022).

Conclusions

The present study is the first report on the distribution of the M470V polymorphism in asthmatic Tunisian patients. We noticed that the M470V variant could modulate the clinical phenotype of asthmatic patients. This preliminary study will establish the molecular basis of this disease in Tunisia.  相似文献

Introduction

Health-related quality of life is an important outcome measurement in the monitoring of asthma control. Self-efficacy is a determinant of self-management behaviors that can contribute to the improvement of asthma control and quality of life. Our objective was to analyze the relationship between self-efficacy and quality of life in children with asthma and their caregivers.

Methods

We included 176 patients aged 6-14 years with asthma, and determined their level of self-efficacy according to three groups (low, medium and high levels). Each child and their main caregiver completed the PAQLQ and PACQLQ questionnaires, respectively.

Results

PAQLQ range = 1-7: 5.61 ± 1.11; PACQLQ range = 1-7: 5.42 ± 1.35; self-efficacy range = 0-60: low level 28.44 ± 4.58; average level 37.41 ± 1.7, and high level 47.50 ± 5.5. Significant differences were observed in quality of life according to low-medium vs. high levels of self-efficacy. Specific related domains: PAQLQ emotions and PAQLQ symptoms with self-efficacy in problem-solving skills related to asthma and treatment self-efficacy; PACQLQ emotions with self-efficacy in problem-solving skills related to asthma.

Conclusions

A high level of self-efficacy is associated with a better quality of life for children and their caregivers. Based on these results, the measurement of self-efficacy could be incorporated in the assessment of educational interventions in self-management targeted at the quality of life of the patient and his or her family.  相似文献

Purpose

This study aimed to investigate whether metformin can affect risk of chronic obstructive pulmonary disease (COPD) in type 2 diabetes (T2D) patients.

Methods

T2D patients newly diagnosed during 1999–2005 were enrolled from the reimbursement database of Taiwan's National Health Insurance system and followed up to 31 December 2011. Analyses were conducted in an unmatched cohort (92,272 ever-users and 10,697 never-users of metformin) and a propensity score (PS) matched pair cohort (10,697 ever-users and 10,697 never-users). Cox regression incorporated into the inverse probability of treatment weighting using the PS was used to estimate hazard ratios (HRs).

Results

In the unmatched cohort, 2573 never-users and 13,840 ever-users developed COPD with respective incidences of 5994.64 and 3393.19 per 100,000 person-years. The overall HR was 0.560 (95% confidence interval [CI]: 0.537–0.584). HRs for the first (< 25.27 months), second (25.27–55.97 months) and third (> 55.97 months) tertiles of cumulative duration were 1.021 (0.975–1.070), 0.575 (0.548–0.603) and 0.265 (0.252–0.280), respectively. Analyses of the matched cohort showed an overall HR of 0.643 (0.605–0.682), with HRs of 1.212 (1.122–1.309), 0.631 (0.578–0.689) and 0.305 (0.273–0.340) for the respective tertiles.

Conclusion

A reduced risk of COPD is observed in metformin users with T2D.  相似文献

Primary Sjögren's syndrome (pSS) is a condition that predominantly affects women. Reports of pregnancy outcome in these patients are limited and contradictory.

Objective

To describe pregnancy characteristics and outcomes and newborn morbidity in women with pSS.

Material and methods

We included women with pSS who became pregnant after the onset of the symptoms of the disease. Clinical and serological characteristics, risk factors and previous maternal comorbidities are described. For each pregnancy in a woman with pSS, we recorded pregnancy course and outcome and newborn condition.

Results

We assessed 11 patients with 18 pregnancies after the onset of pSS symptoms. All of them presented FAN +; 10 anti-Ro / SSA + and 7 anti-La / SSB +. The mean age in years at the onset of symptoms was 24.9 (SD 6.9) and at the time of pregnancy was 30.3 (SD 5.4). Thirteen pregnancies happened before the diagnosis, reporting only one miscarriage. Two preterm births, 1 case of oligohydramnios, 2 of premature membrane rupture and 2 low birthweight babies were reported after the onset of pSS symptoms. There was 1 newborn with congenital atrioventricular block and another with neonatal cutaneous lupus. All the women with pregnancy complications (n = 6) had anti-Ro/SSA antibodies.

Conclusions

Almost half of the pregnancies assessed in women with pSS were associated with complications not attributable to factors other than the disease.  相似文献

Background and aims

Abdominal paracentesis is an area that every general physician should know about, and the current learning model is unsafe for patients. Simulation allows students to develop their skills prior to clinical confrontation with minimal risks. The aims of this study were to design and evaluate a paracentesis simulation workshop for undergraduate students.

Methods

A workshop was implemented using a specially designed and validated simulation model for abdominal paracentesis. The simulated technique considered the recognition of materials, operator equipment, asepsis, anesthesia, puncture and obtaining liquid, collecting samples for analysis, withdrawal of the material and occlusion. A 24-point direct observation checklist was administered to assess the student. We assessed two students at the beginning of the workshop and all the students at the end. A perception survey was applied to attendees at the end of the workshop.

Results

247 students were included and a workshop that involved 8 students per session was held. Students significantly improved their skills comparing pre- and post-evaluation results [13.36 ± 4.46 (55.7%) vs. 22.3 ± 1.83 (92.9%) respectively (n = 69) p < 0.001]. The students’ perception questionnaire (n = 38) showed that the training sessions were highly valued, averaging 4.8 ± 0.38 on a Likert scale of 1–5.

Conclusions

Simulated training in abdominal paracentesis is a very good teaching method. This teaching methodology should be highly recommended as an educational strategy in medicine because it could accelerate the acquisition of clinical skills in a safe learning environment.  相似文献

Objective

To assess the efficacy and side effects of methotrexate and leflunomide in patients with rheumatoid arthritis (RA) as the first disease-modifying antirheumatic drug (DMARD).

Methods

We performed a systematic review and meta-analysis of clinical studies that included patients who took methotrexate, leflunomide, placebo or another DMARD for RA treatment. A systematic review yielded 1971 articles from databases; once completely reviewed, 73 trials that completed inclusion criteria were selected. In structured workshops for discussion and assessment of each article, 6 could be meta-analyzed for the primary and secondary outcomes: achievement of American College of Rheumatology (ACR) 20 and its core set components; and change of serum C-reactive protein (CRP) levels, Health Assessment Questionnaire Disability Index (HAQ-Di), liver enzyme aspartate transaminase/alanine transaminase ratio, new gastrointestinal (GI) side effects and infections.

Results

A total of 1984 patients were included: 986 took leflunomide and 998 methotrexate. The probability of achieving ACR 20 had an odds ratio (OR) of 0.88 (95% confidence interval [CI] 0.74, 1.06) with a trend toward favoring methotrexate; reduction of the swollen joint count was greater for methotrexate: mean difference = 0.82 (95%CI 0.24, 1.39); tender joint count, physician global assessment, HAQ-Di, and serum CRP levels revealed no significant difference between groups. Increased liver enzymes were more frequent in the leflunomide group, OR = 0.38 (95%CI 0.27, 0.53), and new GI complaints were more common with methotrexate (OR = 1.44; 95%CI 1.17, 1.79). There was no difference in the incidence of non-severe infections.

Conclusion

Leflunomide used as the first DMARD in RA seemed to be as efficacious as methotrexate; only the reduction of swollen joint count was more marked for methotrexate. Leflunomide was linked to a greater increase in liver enzymes, but there were fewer GI complaints.  相似文献

Aims

The aim of the present paper was to establish and implement an integrated nursing management model for patients with newly-diagnosed type 2 diabetes mellitus (T2DM) based on the Omaha System and to explore its impact on blood glucose levels, quality of life, and diabetes knowledge in these patients.

Methods

A non-randomized concurrent controlled trial was designed and the study was conducted in a hospital on the east coast of China between September 2013 and November 2015. We screened for patients with newly-diagnosed T2DM in 12 clinics of 3 comprehensive hospitals. A total of 367 patients with newly-diagnosed T2DM were assigned into two groups. In the intervention group, patients received routine outpatient care plus integrated nursing management; in the control group, only routine outpatient care was given. Changes in blood glucose levels, quality of life, and diabetes knowledge in both groups before the intervention and 6 months after the intervention were observed and compared.

Results

At the 6 months, blood glucose levels, quality of life, and diabetes knowledge in the intervention group were significantly superior to those in the control group (all P < 0.01).

Conclusions

The integrated nursing management model was able to improve patients’ glucose levels, quality of life, and diabetes knowledge.  相似文献

Background

Allergy to cow's milk proteins has often been associated with dysfunction of the intestinal mucosa caused by chronic inflammation in infants. This study evaluated the protective effect of taurine on intestinal damage induced by beta-lactoglobulin (β-Lg) in Balb/c mice used as an animal model of allergy to cow's milk proteins.

Methods

Balb/c mice were treated with taurine administered orally by gavage (3 mmol/kg/day) or intraperitoneally (100 mg/kg/day) for two weeks, then sensitized intraperitoneally with β-Lg. The electrophysiological parameters: active ion transport of chloride (Short-circuit current: Isc) and the passive ion permeability (Conductance: G) were measured ex vivo in Ussing chamber by intestine challenge with β-Lg. Histological study was used to assess gut inflammation. Serum levels of TNF-α and IL-6 were measured. Serum IgG and IgE anti-β-Lg were determined by ELISA.

Results

Compared with sensitized mice, β-Lg challenge of intestinal epithelium of taurine-pre-treated mice in Ussing chamber did not influence the intensity of Isc, nor produce any changes in the G, reflecting a reduction in the secretory response and epithelial permeability. Histological and morphometric analysis showed that taurine reduced the intestinal damage and limited intestine retraction caused by β-Lg sensitization. No statistically significant difference in the serum levels of TNF-α or IL-6 was found after oral or intraperitoneal administration of taurine. Treatment with taurine significantly decreased the IgG (p < 0.001) and IgE anti β-Lg levels (p < 0.05).

Conclusions

These results have for the first time provided evidence that pre-treatment with taurine appears to prevent intestinal damage induced by β-Lg.  相似文献
