Background

Cough of more than two weeks has become sine quo non with pulmonary tuberculosis (PTB) in a developing country like India. The causes may be different in patients reporting to respiratory OPD vis a vis general OPD.

Aims and objectives

To study the prevalence of PTB and causes of cough other than PTB among respiratory OPD attendees with cough of more than two weeks duration.

Methods

A cross sectional study was carried out over two years in respiratory OPD of a tertiary care chest center of Indian armed forces. Of the 13,004 patients, 505 non HIV PTB suspects were included. Patients with definitive diagnosis of chronic cough were excluded. Efforts were made to establish diagnosis of pulmonary TB using clinical, microbiological and radiological features. However, patients were also subjected to further evaluation (spirometry, bronchoscopy, CECT) based on clinical features, radiological and lab profile to establish definitive diagnosis.

Results

Out of the 505 patients, 10.5% patients had smear positive pulmonary TB, 13.5% smear negative PTB, bronchial asthma (24%), COPD (9.3%), diffuse parenchymal lung diseases (DPLD's) (12.5%), bronchiectasis (6.3%), lung cancer (5.3%) and congestive cardiac failure (4.2%).

Conclusion

Though prevalence of PTB in the study correlated well with the national statistics, but a significant number of patients had other causes of chronic cough, especially, obstructive airway diseases and DPLDs. Thus, there is a need to spread awareness regarding other causes of chronic cough and all efforts should be made to establish alternate diagnosis especially in patients who do not conclusively have PTB.  相似文献

Background

There is increasing awareness of HBV reactivation in HCV-RNA-positive/HBV-coinfected patients with chronic liver disease (CLD) treated with oral direct-acting antivirals (DAAs).

Aim

To provide figures on the prevalence of HBV markers in HCV-RNA-positive subjects in Italy, where these findings are lacking.

Methods

All subjects aged ≥18?years with CLD consecutively referring to Italian liver units located throughout country were prospectively enrolled in two national surveys in 2001 and 2014.

Results

The total number of HCV-RNA-positive cases was 6984; 356 (5.1%) subjects vaccinated against HBV were excluded. A total of 6628 cases were evaluated. The prevalence rates of HBsAg, isolated anti-HBc and anti-HBc/anti-HBs-positivity were 2.9%, 8.1% and 14.7%, respectively. Among the estimated one million HCV-RNA-positive subjects in Italy, a substantial number of subjects are at risk of HBV reactivation due to DAA therapy. The prevalence of liver cirrhosis was higher than that of CLD in HBsAg-positive subjects (4.4% vs. 2.6%, p?<?0.01) but not in those positive for other HBV markers.

Conclusions

These findings outline the burden of HBV markers among HCV-RNA-positive subjects in Italy, where in 2017 reimbursement for DAA therapy by the National Health System became universal for all patients with chronic HCV infection. HBV vaccination coverage should be greatly extended, since nearly two thirds of subjects in this study resulted negative for any HBV marker.  相似文献

Aims

Gestational diabetes (GDM) and Type 2 diabetes pose tremendous health and economic burdens as worldwide incidence increases. Primary care-based systematic diabetes screening and prevention programs could be effective in women with previous GDM. GooD4Mum aimed to determine whether a Quality Improvement Collaborative (QIC) would improve postpartum diabetes screening and prevention planning in women with previous GDM in general practice.

Methods

Fifteen general practices within Victoria (Australia) participated in a 12-month QIC, consisting of baseline and four quarterly audits, guideline-led workshops and Plan-Do-Study-Act feedback cycles after each audit. The primary outcome measures were the proportion of women on local GDM registers completing a diabetes screening test and a diabetes prevention planning consultation within the previous 15 months.

Results

Diabetes screening increased with rates more than doubled from 26% to 61% and postpartum screening increased from 43%–60%. Diabetes prevention planning consultations did not show the same level of increase (0%–10%). The recording of body mass index improved overall (51%–69%) but the number of women with normal body mass index did not.

Conclusions

GooD4Mum supported increased diabetes screening and the monitoring of high risk women with previous GDM in general practice.  相似文献

Background

Anti-TNF therapies infliximab (IFX), adalimumab (ADA), and golimumab (GOL) are approved for treating moderate to severe ulcerative colitis (UC). In UC, only the switch from IFX to ADA has been investigated, reaching no more than 10–43% remission rates at 12 months.

Aim

Of the present study was to investigate disease outcome after a switch from subcutaneous (SC) agents to the intravenous (IV) agent (IFX).

Methods

In this retrospective multicentre study, we analysed the charts of UC patients unresponsive/intolerant or with secondary loss of response (LOR) to ADA or GOL who were switched to IFX. We evaluated clinical response and remission together with adverse events at 3, 6, and 12 months follow-up.

Results

Seventy-six patients were included; 38 patients started ADA and 38 started GOL for a mean therapy duration of 6?±?6 months. Indications for switch were adverse events in 3%, primary failure in 79%, and LOR in 18% of patients. Clinical remission was reached by 47%, 50%, and 77% of patients, respectively. Patients that switched for LOR did numerically, but not statistically, better than patients who switched for primary failure.

Conclusions

Our data show a superior remission rate in SC to IV anti-TNF switch in UC compared to the IV to SC switch reported in literature.  相似文献

Introduction

Three procedures for rapid identification of microorganisms in positive blood cultures were evaluated.

Methods

We performed two methods based on direct extraction from a blood culture: Sepsityper® (Bruker Daltonics) (ST) and a non-commercial saponin method (MCS), and another method consisting of a short incubation subculture (SIC). Identification values obtained by spectrometry Matrix-Assisted Laser Desorption Ionization-Time of Flight (EM MALDI-TOF) were compared by applying the manufacturer's interpretation criteria and corrected cut-off points.

Results

According to the manufacturer, 65.8%, 45.8% and 57.4% of microorganisms were identified at the species level by using ST, MCS and SIC, respectively. When applying corrected cut-off points, the values increased to 92.3%, 80.6% and 85.2%, respectively. ST offered significantly better results than MCS, and no significant differences were found between ST and SIC, except for with respect to yeast.

Conclusions

Better identification rates were obtained by using ST and SIC, which are easily applicable in any laboratory.  相似文献

Backgound

A significant proportion of hepatitis B surface antigen (HBsAg) negative/anti-hepatitis B core antigen (anti-HBc) positive patients with non-Hodgkin lymphoma (NHL) undergoing rituximab-based chemotherapy (R-CT) may suffer hepatitis B virus (HBV) reactivation.

Aims

We wanted to assess efficacy and safety of lamivudine (LMV) prophylaxis to prevent this complication.

Methods

Eighty-five consecutive HBsAg negative/anti-HBc positive NHL patients (71 years, 100% serum HBV DNA undetectable, 74% anti-HBs positive) received LMV coadministered with R-CT and for 18 months after the end of R-CT. Serum ALT, HBsAg, anti-HBs and HBV DNA were assessed every 4 months during and after end of LMV.

Results

During 39 (2–108) months of study period, including 21 months of LMV and 27 additional months after LMV discontinuation, one patient (2%) had HBV reactivation, 31 months after stopping LMV and during administration of new immunosuppressive regimens, without LMV prophylaxis, owing to incomplete oncological response. A 50% decline of anti-HBs titers occurred in 22/63 (35%) patients, including 12 who became anti-HBs seronegative. Five (6%) patients had ALT increase during R-CT but none required R-CT discontinuation. Seventeen (20%) patients died, all for tumour progression.

Conclusion

LMV prophylaxis is safe and effective in preventing HBV reactivation in HBsAg negative/anti-HBc positive NHL patients receiving R-CT.  相似文献

Aims

To study the association of EMR’s clinical reminder use on a comprehensive set of diabetes quality metrics in U.S. office-based physicians and within solo- versus multi-physician practices. We conducted a retrospective cohort study on visits made by adults with diabetes identified from the National Ambulatory Medical Care Survey (2012–2014).

Methods

Multiple logistic regression is used to test for associations between clinical reminder use and recommended services by the American Diabetes Association.

Results

Of 5508 visits, nationally representing 112,978,791 visits, 31% received HbA1c tests, 13% received urinalysis test, and <10% received retinal or foot exams. Main effects of practice size and clinical reminder use were found for HbA1c, urinalysis, and foot exams. We find no statistically significant relationship to suggest that clinical reminder use improve diabetes process guidelines for solo practices.

Conclusions

Resource efforts, beyond clinical reminders, are needed to reduce gaps in primary diabetes care between solo and non-solo practices.  相似文献

Background

Chronic hepatitis B virus (HBV) infection remains a primary cause of morbidity and mortality worldwide.

Aim

The study is aimed at updating the clinical and epidemiological profile of chronic HBV infection in Italy.

Methods

A cross-sectional multicenter prospective study enrolled consecutive HBsAg positive patients seen in 73 Italian centers in the period 2012–2015. Individual patient data were collected using an electronic platform and analyzed using standard statistical methods.

Results

Among 2877 HBsAg positive individuals (median age 49.8?years, 68% males), 27% were non-Italian natives (NINs); 20% had chronic infection, 58.5% chronic hepatitis and 21.5% cirrhosis. Among NINs, age was younger, male gender was less prevalent and liver disease less advanced than in Italians (all p?<?0.0001). HBeAg positive cases were 23.6% among NINs vs 8.2% in Italians (p?<?0.0001); HDV coinfections 11.1% vs 7.3% (p?=?0.006) and HCV coinfections 2.3% vs 4.2% (p?=?0.017), respectively. Anti-HDV or anti-HCV antibodies were detected more frequently in patients with cirrhosis. Fifty percent of NINs with cirrhosis were aged below 45?years.

Conclusion

The study offers an insight into the evolving burden of chronic hepatitis B virus infection in the near future and highlights new territories for public health interventions.  相似文献

Background

Sigmoid volvulus is a common cause of colonic obstruction in old and frail patients. Its standard management includes the endoscopic detorsion of the colonic loop, followed by an elective sigmoidectomy to prevent recurrence. However, these patients are often poor candidates for surgery.

Aim

The aim of this study was to compare death rate between elective sigmoidectomy and conservative management following endoscopic detorsion for sigmoid volvulus.

Methods

The medical records of 83 patients undergoing endoscopic detorsion of a sigmoid volvulus from 2008 to 2014 were retrospectively reviewed. Patients were divided into two groups: ‘elective surgery’ and ‘no surgery’.

Results

Patients in the ‘no surgery’ group (n?=?42) were older and had more loss of autonomy than in the ‘elective surgery’ group. Volvulus endoscopic detorsion was successful in 96% of patients with no complications. The median follow-up was 13 months (1 day-67 months). The death rate was 62% in the ‘no surgery’ group versus 32% in the ‘elective surgery’ group (p?=?0.02). In the ‘no surgery’ group, 23/42 of patients had volvulus recurrence. No recurrence occurred after surgery.

Conclusion

Elective surgery must be planned as soon as possible after the first episode of sigmoid volvulus. In frail patients, other options must be developed.  相似文献

Background

Biologics against tumor necrosis factor (anti-TNF) have dramatically changed the management of moderate-to-severe ulcerative colitis (UC). In pivotal clinical trials, golimumab showed efficacy as induction and maintenance therapy in anti-TNF naïve UC patients. However, confirmatory data on effectiveness in the real world setting are needed.

Aim

to summarize recent evidence on the effectiveness of golimumab in observational real-world studies.

Methods

A literature search was conducted using Medline, Embase, and congresses databases for English language articles or abstracts on the effectiveness of golimumab published between January 1, 2014 and May 15, 2018. Pooled short-term (6–14 weeks) and mid- and long-term (24–54 weeks) clinical response and remission rates were calculated.

Results

24 abstracts were included; of those 8 were published full-text articles and 16 were abstracts from medical conferences. Overall, pooled short-term clinical response and remission rates were 59.3% (range 35–85.5%; 13 studies; 1429 patients) and 35.9% (range 14–51.7%; 9 studies; 666 patients), respectively. Pooled mid- and long-term clinical response and remission rates were 60.3% (range 37.1–89.5%; 4 studies; 356 patients) and 39.2% (range 12–84%; 8 studies; 822 patients), respectively.

Conclusions

Results: of observational studies confirm that golimumab is an effective therapy for UC in clinical practice.  相似文献

Background

The long-term management of perianal Crohn’s disease for patients on anti-TNF-α therapy remains challenging.

Aim

To evaluate the long-term course and complications of patients with perianal fistulas treated with anti-TNF-α based on their clinical remission and healing on MRI.

Methods

Patients were evaluated clinically and by MRI. Deep remission was defined as clinical remission associated with the absence of contrast enhancement and T2 hyperintensity on MRI. Flare-free survival, surgery and hospitalizations were compared based on the presence or not of deep remission.

Results

Forty-eight consecutive patients were included with a median follow-up of 62?months after anti-TNF-α first administration. Deep remission was observed in 16 patients (33.4%). For patients in deep remission, the median time to any perianal event was 116?months (95–130) versus 42?months (8–72) in patients with pathological MRI (p?<?0.001). Sixteen patients (50%) with pathological MRI had perianal surgery versus 2 (12.5%) in the deep remission group (p?<?0.05). The mean duration of cumulative hospital stays was 0.75?±?0.52?days in the deep remission group versus 19.7?±?7.4 in the pathological group (p?<?0.05).

Conclusions

Higher flare-free survival and lower rates of surgery and hospitalization were found in patients achieving deep remission.  相似文献

Background

Few studies on the age of resolution of Food Protein Induced Enterocolitis Syndrome (FPIES) induced by solid foods are available. In particular, for FPIES induced by egg, the mean age of tolerance acquisition reported in the literature ranges from 42 to 63 months.

Objective

We have assessed whether the age of tolerance acquisition in acute egg FPIES varies depending on whether the egg is cooked or raw.

Methods

We conducted a retrospective and multicentric study of children with diagnosis of acute egg FPIES seen in 10 Italian allergy units between July 2003 and October 2017. The collected data regarded sex, presence of other allergic diseases, age of onset of symptoms, kind and severity of symptoms, cooking technique of the ingested egg, outcome of the allergy test, age of tolerance acquisition.

Results

Sixty-one children with acute egg FPIES were enrolled, 34 (56%) males and 27 (44%) females. Tolerance to cooked egg has been demonstrated by 47/61 (77%) children at a mean age of 30.2 months. For 32 of them, tolerance to raw egg has been demonstrated at a mean age of 43.9 months. No episodes of severe adverse reaction after baked egg ingestion have been recorded.

Conclusions

It is possible to perform an OFC with baked egg, to verify the possible acquisition of tolerance, at about 30 months of life in children with acute egg FPIES.  相似文献

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

Background

Reflex testing of antibodies and viral load in the same sample for diagnosing hepatitis C virus infection speeds up access to treatment. However, how hepatitis C is diagnosed in Spanish hospitals is unknown.

Objective

To describe the available resources and procedures for the diagnosis of hepatitis C virus infection in Spain.

Methods

Survey sent to public and private Spanish hospitals with teaching accreditation with at least 200 beds.

Results

Of the 160 hospitals that met the inclusion criteria, 90 centres (response rate 56.3%) completed the survey. Two hospitals (2.2%) have no diagnostic resources, 15 (16.7%) can only test for anti-hepatitis C virus(Ab), 9 (10.0%) for Ab and viral load, 47 (52.2%) for Ab, viral load and genotype, 2 (2.2%) for Ab, viral load and core antigen, and 15 (16.7%) can perform Ab, core antigen, viral load and genotype tests. When an Ab test is positive, 28 (31.1%) hospitals perform reflex testing. When an active infection is diagnosed, some communication strategy is used in 62 (68.9%) hospitals. Approximately 44.2% of the respondents believe that all determinations needed to reach a definitive diagnosis should be done on a single blood sample.

Conclusion

Although 81% of Spanish hospitals have the resources to perform reflex hepatitis C virus infection testing, it is only done in 31%, and less than a half of respondents believe that the definitive diagnosis should be performed on a single sample.  相似文献

Background

The growing number of gastric cancers together with improved survival resulted in an increasing population of survivors at risk of multiple primary cancers.

Aims

To estimate the 10-year risk and survival of third primary cancers (TPCs) among gastric first primary cancers (FPCs).

Methods

Gastric FPCs from the Portuguese North Region Cancer Registry, diagnosed in 2000-2006 (n?=?7409), were followed for a TPC (31/12/2012), and for all-cause death (31/12/2017). The cumulative incidence of TPCs was estimated. Patients with a TPC were matched (1:1, by sex, age group, years between FPC and second primary cancer [SPC] diagnosis, and SPC location) to FPC?+?SPC patients without a TPC.

Results

Overall, 25 (0.3% of FPCs and 6.8% of SPCs) TPCs were diagnosed. The most common sites were tobacco-related, mainly including digestive organs. Among all FPCs, 10-year cumulative incidence (95% confidence interval [CI]) of a TPC was 0.4% (0.2–0.5%) and among SPCs 7.6% (4.4–10.8%). For TPCs, compared to matched patients, age-adjusted hazard ratio (95%CI) for death was 1.68 (0.77–3.67). The 10-year cumulative mortality of TPCs and matched patients was 92.6% and 67.9%, respectively.

Conclusions

A clustering of tobacco-related cancers was observed in TPCs, with a 10-year cumulative incidence of 0.4% among FPCs. TPCs had worse survival than patients without a TPC.  相似文献

Aim

To describe quality management processes and appropriate interpretation with respect to HbA1c point-of-care (POC) testing in a national diabetes and cardiovascular risk screening programme.

Methods

We compared HbA1c results from capillary blood, measured by the cobas b 101 (Roche Diagnostics) POC testing system, with results from venous blood measured by accredited laboratory analysers to inform national screening practice and a (separately-reported) randomised controlled trial. Difference plots and regressions were used to aid interpretation around 40 and 50 mmol/mol, the cut-offs used to identify “pre-diabetes” and diabetes in New Zealand.

Results

After initial acceptable tests, subsequent batches delivered POC results that varied from laboratory HbA1c by +6 to ?14 mmol/mol around the clinical cut-offs. Ten faulty batches of discs were recalled worldwide. POC testing was suspended in one region, as was the planned trial. The manufacturing defect was rectified, accuracy of the new batches was confirmed, and testing resumed.

Conclusion

POC testing must be conducted within stringent quality assurance processes prior to and while in use. Within such a system, POC testing for HbA1c can be sufficiently accurate for screening and diagnosis of diabetes.  相似文献

Background

Cholangiocarcinoma (CCA) represents a devastating malignancy characterized by high mortality, and notoriously problematic to diagnose. Recently, microRNAs (miRs) have been intensively investigated due to their potential usefulness from a tumor treatment perspective.

Aims

The current study was aimed to investigate whether miR-494 influences epithelial-mesenchymal transition (EMT), tumor growth and metastasis of CCA.

Methods

The regulatory miRNAs of WDHD1 in CCA expression chip were predicted, followed by determination of the miR-494 and WDHD1 expression in normal cholangiocyte tissues and CCA tissues. The related protein levels were determined. CCA cell migration, invasion, viability, and cell cycle distribution and the dosage-dependent effect of miR-494 on CCA cell growth were subsequently detected. Finally, tumorigenicity and lymph node metastasis (LNM) were measured.

Results

Initially, miR-194 affected the CCA development via negatively regulating WDHD1 and miR-494 which were downregulated while WDHD1 was upregulated in CCA. In addition, miR-494 overexpression elevated E-cadherin expression while decreased expressions of WDHD1, N-cadherin, Vimentin, Snail, Twist and MMP-9. Finally, overexpressed miR-494 was observed to suppress EMT, cell viability, migration, invasion, arrest cell cycle progression, tumor formation, and LNM while accelerating cell apoptosis in vivo.

Conclusion

This study indicated that miR-494 overexpression suppresses EMT, tumor formation and LNM while promoting CCA cell apoptosis through inhibiting WDHD1 in CCA.  相似文献
