A Study on Internal Service Recovery Strategy Using CIT from the First Line Staff's Perspective

Service is a special product. It is intangible and unstored, so service er-rors are not avoided. Once service errors appear, the first line staffs who keep di-rect touch with customers wil play an important role in service recovery. The staffs＇ negative emotions during the recovery service should be recovered by internal ser-vice recovery. In this paper, critical incident technique is applied to analyse the re-covery strategies expected by the first line staff and the internal service recovery strategies such as inspiring, authorization, training and psychology service are put forward. the strategy most expected by the staff is reward.

Patient and Health System Factors Associated with First Line Tuberculosis Treatment Adherence, 2009-2014

Background: The prevalence and incidence rate of tuberculosis remains high although the disease is known to be almost always curable provided the patient adheres to the treatment regimen. This study assessed the strength of association between known patient and health system factors associated with first line tuberculosis treatment adherence. Methods: A quantitative cross sectional study. Retrospective chart reviews were conducted among 570 persons who had primary tuberculosis and received first line treatment at a health facility within the Nkangala district, Mpumalanga province and who had a treatment outcome recorded between 1st January 2009 and 31st December 2014. Adherence to first line tuberculosis treatment was defined as taking ≥80% of tuberculosis prescribed drugs within a period of 6 to 8 months. Stata software (logistic regressions model) was used to analyze results and find the strength of association between known factors and treatment adherence. Results: Out of the 570 study participants, 473 were adherent and 96 were not adherent. There was a statistically significant association between age 18 years and above (OR: 1.02, P-value: 0.027), sex (lower in males OR: 0.44, P-value: 0.001) and support (OR: 3.04, P-value: 0.05) and HIV (OR: 1, P-value: 0.634) and first line TB treatment adherence. Conclusion and Recommendation: >80% adherence to first line tuberculosis outcome is possible. The support given to people with tuberculosis will further enhance adherence to first line tuberculosis treatment.

First Line Anti-Tuberculosis Drugs Resistance Patterns of <i>Mycobacterium tuberculosis</i>Isolates from Newly Diagnosed Cases of Tuberculosis

Introduction: Tuberculosis is a major cause of mortality and morbidity world-wide. Anti-tuberculosis drugs have been used for many decades but resistance to them is now widespread. Globally 5% of tuberculosis cases and in India 3% among new TB cases. This study was planned to know the pattern of first line anti-tuberculosis drug resistance in south Gujarat, Surat region in newly diagnosed patients of tuberculosis. Material and Methods: 350 samples were processed for homogenisation and concentration using 4% NAOH-2.9% trisodium citrate. Processed samples were inoculated in liquid medium that is MGIT (Mycobacterial growth indicator tube). Positive samples for M. tbwere processed further for first line anti-tuberculosis drugs sensitivity testing (DST). Reading was taken by using MicroMGIT system. Result: Out of 350 samples 59 (17%) were positive samples, of which 48 (13%) were M. tb and 11 (3%) were non tuberculous mycobacteria. Out of 48 samples 2% (1 isolate) was resistant to isoniazid and Rifampicin while 2% were monoresistant to isoniazide, 2% monoresistant to streptomycin. No rifampicin monoresistant was detected. Conclusion: Such study may help in control of tuberculosis at regional and national level which would in turn help in planning of measures to control Multi-drug resistance tuberculosis. Continuous surveillance should be applied to know the periodic changing patterns and trend in Drug resistant tuberculosis.

Immunovirologic Evaluation of Triomune (Lamivudine, Stavudine and Nevirapine) Antiretroviral Therapy in First Line HIV-1 Adult Patients in N’Djamena, Chad

Contexte:?The fight against HIV/AIDS epidemics is one of the greatest challenges of this century. The epidemic affects generally under-developed countries, and Sub-Saharan Africa are the most concerned. The combined marketed form known as Triomune was used as first-line treatment in several sub-Saharan African Countries (60% of VIH infected people), including Chad. However, no evaluation has been done for that treatment in the country. Objective: To evaluate the efficacy and safety immuno-virological of Triomune at the General Hospital in N’Djamena/Chad. Methods: 48 HIV-1 positive patients eligible for ARV treatment were enrolled in our study, and they have been then followed for 8 months. We have measured in these patients the CD4 cell count before treatment and at the 8th month of treatment. After 8 months of treatment, we have also evaluated the Lymphocyte T CD4 and the plasma viral load (VL). Comparisons of means of CD4 lymphocytes and plasma CV (≥1000 copies/ml) were used to define treatment failure.?Results:?48 patients were under Triomune regime. The average CD4 count was decreased from 462 ± 179.22 [56 - 981] cells/mm3?before treatment to 327.23 ± 153.77 [10 - 1008] cells/mm3?at the 8th month of treatment. The mean plasma viral load for patients was 66008.62 copies/ml. The failure rate to Triomune was 43.75% (21/48).?Conclusion:?Aside from the side effects already described for Triomune, our study reveals a high treatment failure rate. Hence, there is the need of regular revisions of therapeutic regime administer in the first intention.

Use of Cost Effective Semi-Automated (Mannual/Micro) MGIT System over BACTEC 960 to Perform First Line Anti-Tuberculosis Drugs Sensitivity Testing

Introduction: Multi-drug resistant tuberculosis (MDR-TB) that is the tuberculosis that is resistant to at least 2 of the first line anti-tuberculosis drugs is fatal infectious disease. Cases of MDR-TB are now increasing with 30,000 cases of MDR-TB reported in 2013 by national TB programme. Rapid diagnosis of MDR-TB is extremely important for rapid treatment of patient and to prevent spread of MDR-TB to other. BACTEC 960 system helps in rapid diagnosis but purchase of expensive instrument for the same is the limitation. However, the same purpose can be solved by use of semi-automated MGIT system. Aims and Objectives: Aim of this study is to do drug sensitivity testing of the first line anti-tuberculosis drugs with the use of semi-automated MGIT systems. 350 newly registered and suspected cases of tuberculosis in tertiary care hospital were included. Samples were processed for digestion and decontamination and inoculated in MGIT tubes and also on LJ medium. Reading was taken using semi-automated MGIT system. Positive tubes were confirmed by rapid test for M. tuberculosis and then drug sensitivity was performed. Result: Out of 350 samples, 62% were sputum;33% were pleural fluid and rest 5% were lymph node, Ascetic fluid, CSF, pus. Average day of positivity by MGIT was 13 - 20 days as compared to 25 - 37 days by solid medium, which was statistically significant with p value Conclusion: Manual MGIT System is a simple, efficient, safe to use diagnostic system. It does not require any expensive/special instrumentation other than the UV lamp for detection of fluorescence. The rapidity by which mycobacteria are detected is the most important advantage of the Manual MGIT. In areas with limited resources where purchase of expensive instruments such as the MGIT960 is out of scope, the use of manual MGIT for rapid susceptibility testing for MDR-TB could be a possibility.

Research Progress of Radical Treatment of Helicobacter Pylori Based on Drug Sensitivity Test as First-Line Treatment

Helicobacter pylori (HP) infection is a global problem that affects about half of the world’s population and requires sufficient attention in clinical and scientific work. Due to differences in economic and medical conditions among countries around the world, there is currently no unified treatment plan for anti-HP. In China, empirical quadruple therapy is mainly used. With the abuse of antibiotics, many patients face the problem of secondary eradication after failure, and the resistance rate of HP is gradually increasing. After eradication failure, drug sensitivity cultivation is carried out to choose sensitive antibiotics for treatment. A new strategy is currently needed to address how to improve the eradication rate of HP during the first eradication. This article aims to discuss the first-line treatment plans and research progress for eradicating HP based on drug sensitivity testing before eradication. Compared with traditional empirical therapies, treatment based on drug sensitivity results can effectively improve the eradication rate of HP, and reduce drug resistance rates, and adverse reactions, among other benefits. .

Role of cetuximab in first-line treatment of metastatic colorectal cancer

The treatment of metastatic colorectal cancer(mCRC)has evolved considerably in the last decade,currently allowing most mCRC patients to live more than two years.Monoclonal antibodies targeting the epidermal growth factor receptor(EGFR)and vascular endothelial growth factor play an important role in the current treatment of these patients.However,only antibodies directed against EGFR have a predictive marker of response,which is the mutation status of v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog(KRAS).Cetuximab has been shown to be effective in patients with KRAS wild-type mCRC.The CRYSTAL study showed that adding cetuximab to FOLFIRI(regimen of irinotecan,infusional fluorouracil and leucovorin)significantly improved results in the first-line treatment of KRAS wildtype mCRC.However,results that evaluate the efficacy of cetuximab in combination with oxaliplatin-based chemotherapy in this setting are contradictory.On the other hand,recent advances in the management of colorectal liver metastases have improved survival in these patients.Adding cetuximab to standard chemotherapy increases the response rate in patients with wild-type KRAS and can thus increase the resectability rate of liver metastases in this group of patients.In this paper we review the different studies assessing the efficacy of cetuximab in the first-line treatment of mCRC.

Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer:A phase II open-label clinical study

Objective: The aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel(nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer(NSCLC).Methods: A total of 84 participants received either 100 mg/m^2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m^2 on d 1 every three weeks(nab-TP arm); or gemcitabine 1,000 mg/m^2 on d 1 and 8, plus cisplatin 75 mg/m^2 on d 1 every three weeks(GP arm). The primary end point was progression-free survival(PFS). The secondary end points were overall response rate(ORR) and overall survival(OS).Results: According to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm(P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm(P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor(EGFR) mutation(26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0(23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.Conclusions: Therefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials.

Efficacy of moxifloxacin-based sequential and hybrid therapy for first-line Helicobacter pylori eradication

AIM: To evaluate the efficacy of moxifloxacin-based sequential therapy(MBST) versus hybrid therapy as a first-line treatment for Helicobacter pylori(H. pylori) infection.METHODS: From August 2014 to January 2015, 284 patients with confirmed H. pylori infection were randomized to receive a 14-d course of MBST(MBST group, n = 140) or hybrid(Hybrid group, n = 144) therapy. The MBST group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 7 d, followed by 20 mg rabeprazole and 500 mg metronidazole twice daily, and 400 mg moxifloxacin once daily for 7 d. The Hybrid group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 14 d. In addition, the Hybrid group received 500 mg metronidazole and 500 mg clarithromycin twice daily for the final 7 d. Successful eradication of H. pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of treatment. Patient compliance was defined as "good" if drug intake was at least 85%. H. pylori eradication rates, patient compliance with treatment, and adverse event rates were evaluated.RESULTS: The eradication rates in the intention-totreat(ITT) analysis were 91.4%(128/140; 95%CI: 90.2%-92.9%) in the MBST group and 79.2%(114/144; 95%CI: 77.3%-80.7%) in the Hybrid group(P = 0.013). The eradication rates in the perprotocol(PP) analysis were 94.1%(128/136; 95%CI: 92.9%-95.6%) in the MBST group and 82.6%(114/138; 95%CI: 80.6%-84.1%) in the Hybrid group(P = 0.003). The H. pylori eradication rate in the MBST group was significantly higher than that of the Hybrid group for both the ITT(P = 0.013) and the PP analyses(P = 0.003). Both groups exhibited full compliance with treatment(MBST/Hybrid group: 100%/100%). The rate of adverse events was 11.8%(16/136) and 19.6%(27/138) in the MBST and Hybrid group, respectively(P = 0.019). The majority of adverse events were mild-to-moderate in intensity; none were severe enough to cause discontinuation of treatment in either group.CONCLUSION: MBST was more effective and led to fewer adverse events than hybrid therapy as a first-line treatment for H. pylori infection.

Efficacy of moxifloxacin-based sequential therapy for first-line eradication of Helicobacter pylori infection in gastrointestinal disease

AIM:To evaluate the efficacy of 14-d moxifloxacinbased sequential therapy as first-line eradication treatment of Helicobacter pylori(H.pylori) infection.METHODS:From December 2013 to August 2014, 161 patients with confirmed H.pylori infection randomly received 14 d of moxifloxacin-based sequential group(MOX-ST group, n = 80) or clarithromycin-based sequential group(CLA-ST group, n = 81) therapy.H.pylori infection was defined on the basis of at least one of the following three tests:a positive 13C-urea breath test; histologic evidence of H.pylori by modified Giemsa staining; or a positive rapid urease test(CLOtest; Delta West, Bentley, Australia) by gastric mucosal biopsy.Successful eradication therapy for H.pylori infection was defined as a negative 13C-urea breath test four weeks after the end of eradication treatment.Compliance was defined as good when drug intake was at least 85%.H.pylori eradication rates, patient compliance with drug treatment, adverse event rates, and factors influencing the efficacy of eradication therapy were evaluated.RESULTS:The eradication rates by intention-to-treat analysis were 91.3%(73/80;95%CI:86.2%-95.4%)in the MOX-ST group and 71.6%(58/81;95%CI:65.8%-77.4%)in the CLA-ST group(P=0.014).The eradication rates by per-protocol analysis were 93.6%(73/78;95%CI:89.1%-98.1%)in the MOX-ST group and 75.3%(58/77;95%CI:69.4%-81.8%)in the CLAST group(P=0.022).Compliance was 100%in both groups.The adverse event rates were 12.8%(10/78)and 24.6%(19/77)in the MOX-ST and CLA-ST group,respectively(P=0.038).Most of the adverse events were mild-to-moderate in intensity;there was none serious enough to cause discontinuation of treatmentin either group.In multivariate analysis,advanced age(≥60 years)was a significant independent factor related to the eradication failure in the CLA-ST group(adjusted OR=2.13,95%CI:1.97-2.29,P=0.004),whereas there was no significance in the MOX-ST group.CONCLUSION:The 14-d moxifloxacin-based sequential therapy is effective.Moreover,it shows excellent patient compliance and safety compared to the 14-d clarithromycin-based sequential therapy.

Non-bismuth quadruple therapy for first-line Helicobacter pylori eradication:A randomized study in Japan

AIM:To find the way to improve the eradication rate of first-line therapy in Japanese patients.METHODS:We prospectively compared the effectiveness of 7-d quadruple therapy to standard 7 d triple therapy in Japanese patients infected with Helicobacter pylori(H.pylori).One hundred and nineteen patients were randomly assigned to receive 7-d non-bismuth quadruple therapy with lansoprazole,amoxicillin,clarithromycin and metronidazole(LACM7) or 7-d triple therapy with lansoprazole,amoxicillin and clarithromycin(LAC7).After three months,H.pylori status was analyzed by 13C-urea breath test.Incidence rates of adverse events were evaluated by use of questionnaires.RESULTS:By intention-to-treat(ITT) analysis,the eradication rate in the LACM7 group was 94.9%,which was significantly higher than the LAC7 group(68.3%,P < 0.001).Per protocol analysis also showed a significantly higher eradication rate in the LACM7 group(98.3%) than the LAC7 group(73.2%,P < 0.001).Nevertheless,the incidence of serious adverse events did not differ between the two groups(RR:1.10,95% CI:0.70-1.73,P = 0.67).CONCLUSION:Seven day non-bismuth quadruple therapy(LACM7) was superior to standard 7-d triple therapy(LAC7) for first-line eradication.

Efficacy of gefitinib as a first-line single agent treatment in patients with advanced non-small cell lung cancer

Objective： To assess the efficacy and toxicity of gefitinib as a single agent treatment in Chinese patients with advanced non-small cell lung cancer （NSCLC）. Methods： Forty-five patients with advanced NSCLC were treated with gefitinib at 250 mg daily until the disease progressed or the patient could not tolerate the toxicity. Results： None of the patients achieved a complete response （CR）, while 15 patients achieved a partial remission （PR） and 17 experienced a stable disease （SD）. Thirteen patients continued to have a progressive disease （PD）. The response rate and the disease control rate were 33.3% and 71.1%, respectively. The symptom remission rate was 72.5%, and the median remission time was 8 days. The median survival time was 15.3 months. The median progression-free survival time was 6.0 months. The most common toxicities included rash （53.3%） and diarrhea （33.3%）. Dehydration and pruritus of the skin developed in 26.7% and 22.2% of the patients, respectively. Hepatic toxicity occurred in 6.7% of patients and oral ulceration occurred in 4.4% of patients. Conclusion： Single agent treatment with gefitinib is effective against advanced NSCLC, and is well tolerated in Chinese patients.

Efficacy and Safety of Axitinib as First-Line Therapy in Japanese Patients with Metastatic Renal Cell Carcinoma

Previous study reported that patients treated with axitinib as second-line therapy had longer median progression-free survival than those treated with sorafenib for metastatic renal cell carcinoma (mRCC). In this study, we reviewed our experience of axitinib as a first-line therapy for mRCC in Japanese patients, focusing on its efficacy and safety. We retrospectively assessed 26 patients treated with axitinib as a first-line therapy for mRCC from July 2010 to July 2014 at Chiba Cancer Center and Kinki University Hospital. Observation period was 24.6 ± 18.3 months. The objective response rate was 50.0%, and the median progression-free survival was 27.5 months. Overall survival was not estimable. Common grade 3 adverse events were hypertension in 19 patients and proteinuria in 5 patients. Axitinib demonstrated significant efficacy as a first-line therapy in Japanese patients with mRCC. Careful monitoring and management of the adverse effects may help to control its toxicities.

FOLFOXIRI vs FOLFIRINOX as first-line chemotherapy in patients with advanced pancreatic cancer: A population-based cohort study

BACKGROUND FOLFIRINOX regimen is the first-line reference chemotherapy(L1)in advanced pancreatic ductal adenocarcinoma(aPDAC).FOLFOXIRI,a schedule with a lower dose of irinotecan and no bolus 5-fluorouracil,has demonstrated efficacy and feasibility in colorectal cancer.AIM To investigate the potential clinical value of FOLFOXIRI in patients with aPDAC in routine clinical practice.METHODS Analyses were derived from all consecutive aPDAC patients treated in L1 between January 2011 and December 2017 in two French institutions,with either FOLFOXIRI(n=165)or FOLFIRINOX(n=124)regimens.FOLFOXIRI consisted of irinotecan(165 mg/m2),oxaliplatin(85 mg/m2),leucovorin(200 mg/m2)and 5-fluorouracil(3200 mg/m2 as a 48-h continuous infusion)every 2 wk.Ninety-six pairs of patients were selected through propensity score matching,and clinical outcomes of the two treatment regimens were compared.RESULTS Median overall survival was 11.1 mo in the FOLFOXIRI and 11.6 mo in the FOLFIRINOX cohorts,respectively.After propensity score matching,survival rates remained similar between the two regimens in terms of overall survival(hazard ratio=1.22;P=0.219)and progression-free survival(hazard ratio=1.27;P=0.120).The objective response rate was 37.1%in the FOLFOXIRI group vs 47.8%in the FOLFIRINOX group(P=0.187).Grade 3/4 toxicities occurred in 28.7%of patients in the FOLFOXIRI cohort vs 19.5%in the FOLFIRINOX cohort(P=0.079).FOLFOXIRI was associated with a higher incidence of grade 3/4 digestive adverse events.Hematopoietic growth factors were used after each chemotherapy cycle and the low hematological toxicity rates were below 5%with both regimens.CONCLUSION FOLFOXIRI is feasible in L1 in patients with aPDAC but does not confer any therapeutic benefit as compared with FOLFIRINOX.The low hematological toxicity rates strengthened the relevance of primary prophylaxis with hematopoietic growth factors.

The Effect of the First order Responses of Mooring Line on the Second order Mooring Line Damping

In this paper we investigated the effect of the first order responses of mooring line on the second order mooring line damping.In the study of the slow oscillating of a moored floating structure by perturbation method in frequency domain,the second order equations of the mooring line are divided into non homogeneous and homogeneous equations.The solutions are related to the first order responses of mooring line and second order floating structure oscillation respectively.In order to find the effect of the first order responses of mooring line,the second order mooring line tension and damping were determined by solving the non homogeneous equation and homogeneous equation.From the results,we found,although the second order mooring line tension obtained from the non homogenous equation is quite small compared with the total second order mooring line tension,the damping contributed from both of them are in the same order in quantity.So,in predicting the second order mooring line damping,the effect of the solution related to the non homogeneous equation can not be omitted.
