RESUMEN

PURPOSE: To assess the effects of dietary and physical activity (PA) interventions on generic and cancer-specific quality of life (QoL), anxiety, and depression levels among adult Chinese colorectal cancer (CRC) survivors. METHODS: Two-hundred twenty-three adult CRC survivors within 1 year of completion of primary cancer treatment were randomized to receive dietary, PA or combined intervention, or usual care for a 12 monthduration, under a 2 (diet vs usual care) × 2 (PA vs usual care) factorial design. Generic and cancer-specific QoL was assessed using a Chinese version 12-Item Short Form Health Survey (SF-12) and the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) scale, respectively. Anxiety and depression was assessed using the Hospital Anxiety and Depression Scale at baseline, 6, 12, 18, and 24 months. Linear mixed models were used for examining the intervention effects. RESULTS: Participants receiving dietary intervention experienced a significant improvement in the generic measure of QoL (SF-6D utility scores, mean difference 0.042, 95%CI 0.03 to 0.081) at 12 months, the cancer-specific QoL scores (mean difference 3.09, 95%CI 0.13 to 6.04), and levels of depression (P = 0.015) at both 12 and 24 months follow-up. Participants receiving PA intervention only demonstrated a significant improvement in SF-6D utility index (mean difference 0.039, 95%CI 0.002 to 0.077) and physical functioning (mean difference 2.85, 95%CI 1.00 to 4.70) at 6 months. CONCLUSIONS: Dietary intervention improved the generic and cancer-specific QoL and depression in CRC survivors. TRIAL REGISTRATION: The study was prospectively registered on 17 October 2012 at ClinicalTrials.gov (NCT01708824). IMPLICATIONS FOR CANCER SURVIVORS: CRC survivors can benefit from dietary interventions in alleviating depression and improving overall health-related QoL.

RESUMEN

PURPOSE: To compare febrile neutropenia (FN) incidence and hospitalization among breast cancer patients on docetaxel with no granulocyte colony-stimulating factors (GCSF) primary prophylaxis (PP), 4/5-day PP, or 7-day PP. METHODS: We identified 3916 breast cancer patients using docetaxel-cyclophosphamide (TC), doxorubicin-cyclophosphamide then docetaxel (AC-T), fluorouracil-epirubicin-cyclophosphamide then docetaxel (FEC-T), docetaxel-carboplatin-trastuzumab (TJH), or docetaxel-doxorubicin-cyclophosphamide (TAC) from a hospital pharmacy dispensing database in Hong Kong between 2014 and 2016. Patients were offered GCSF within 5 days since administering docetaxel. Outcomes included FN incidence, time to first hospitalization, hospitalization rate, and duration. RESULTS: In TC regimen, FN incidence (with odds ratio, OR) of patients with no PP, 4/5-day PP, and 7-day PP was 21.69%, 7.95% (OR 0.31, p < 0.001), and 5.33% (OR 0.20, p < 0.001), respectively. In TJH regimen, FN incidence of patients with no PP, 4/5-day PP, and 7-day PP was 38.26%, 8.33% (OR 0.15, p < 0.001), and 8.57% (OR 0.15, p < 0.001), respectively. FN incidence of patients on AC-T regimen with no PP and 4/5-day PP was 20.93% and 6.84%, respectively (OR 0.28, p = 0.005); with FEC-T regimen, the incidence was 9.91% and 4.77%, respectively (OR 0.46, p = 0.035). Only 3.27% FN cases were not hospitalized. Mean (±standard deviation, SD) time to first hospitalization was 8.21 ± 2.44 days. Mean (±SD) duration of hospitalization for patients with no PP, 4/5-day PP, and 7-day PP was 4.66 ± 2.60, 4.37 ± 2.85, and 5.12 ± 2.97 days, respectively. CONCLUSION: GCSF prophylaxis in breast cancer patients on docetaxel could reduce FN incidence and hospitalization. 4/5-day PP demonstrated similar efficacy to 7-day PP with superior saving benefits on healthcare expenditure.

RESUMEN

There has been evidence on the protective effects of diets high in fiber and low in red and processed meat (RPM), and physical activity (PA) against colorectal cancer (CRC) development, but that against CRC recurrence has been limited. This study evaluated the efficacy of a behavioral program comprising dietary and PA interventions in improving Chinese CRC survivors' lifestyle. A 2 × 2 factorial randomized controlled trial of 223 CRC patients (82 females, mean age 65), randomly assigned to receive dietary, PA or both interventions, or usual care for 12 months, and assessed every 6 months for 24 months. Primary outcomes included two dietary and two PA targets. Secondary outcomes included changes in dietary consumptions and PA levels. Dietary interventions significantly increased the odds of achieving the targets of consuming less RPM at all time-points (OR 3.22-4.57, all p < 0.01) and refined grain (RG) at months 6 (OR 3.13, p = 0.002) and 24 (OR 2.19, p = 0.039), and reduced RPM (2.49-3.48 servings/week, all p < 0.01) and RG (0.31-0.5 servings/day, all p < 0.01) consumptions. Patients receiving PA interventions potentially spent more time on moderate-to-vigorous PA. This study demonstrated the efficacy of a behavioral program in improving dietary habits of Chinese CRC survivors.

RESUMEN

Indications of liver transplantation are extensive, but deceased donation does not meet the demand. Hepatitis B surface antigen (HBsAg)-positive grafts used to be discarded in the past. The aim of this study was to examine viral activity and outcome of HBsAg-positive deceased grafts transplanted to HBsAg-positive recipients. Eleven HBsAg-positive deceased grafts were transplanted to HBsAg-positive patients with acute liver failure (3 patients), hepatocellular carcinoma (6 patients) and repeatedly bleeding varices (2 patients). Postoperatively, hepatitis B virus (HBV) infection was treated by a combination of antiviral nucleoside and nucleotide analogues. HBV DNA and HBsAg were measured periodically. The median (interquartile) model of end-stage liver disease score for the recipients was 19 (16-32) with a range from 11 to 40. HBV DNA was detected in 6 patients with a range from 61 to 1083 IU/mL before transplantation. After transplantation, HBV DNA was detected in 4 patients in the first month and 2 patients in the 6th month and became undetectable for all patients at end of the first year. The quantitative HBsAg ranged from 0.86 to 241.1 IU/mL at 6 months and 0.34 to 238.5 IU/mL at 24 months (P = .135). Three of the patients died in the early phase, and the other patients were followed up for 40.0 ± 19.2 months with normal liver function. In conclusion, HBsAg-positive deceased liver grafts function well with minimal viral activity under treatment of combined antiviral nucleoside and nucleotide analogues. Use of HBsAg-positive deceased grafts is feasible and increases the donor pool to rescue dying patients.

RESUMEN

Helping breast cancer patients who desire a pregnancy after cancer treatment is a vital issue. Little is known about the complex context of the decision to become pregnant after breast cancer treatment. The purpose of this study was to understand the risk-benefit perception of choosing conception or contraception after treatment in Taiwan. We applied grounded theory to guide this exploratory qualitative study. Data were collected through in-depth interviews with 16 breast cancer patients. Pregnancy was addressed in the context of cancer as a potentially life-threatening diagnosis and its treatment. The verbatim transcriptions were analysed using constant comparative analysis and methods of open, axial and selective coding. The core theme that described the risk perception of pregnancy among patients with breast cancer after treatment focused on "reaching the balance of life." Seven dimensions of risk-benefit perception of pregnancy, including perceived health status, safety, expected gain, harm, loading, support and time were explored among women treated for breast cancer. We found that women treated for breast cancer applied risk-benefit perceptions to decide whether to become pregnant. Implementing contextual counselling could help to decrease perceived barriers to choose pregnancy and increase the quality of pregnancy care.

RESUMEN

BACKGROUND: Currently, pancreas transplantation has been a promising strategy to restore long-term normoglycemia as well as to improve life quality for patients with insulin-dependent diabetes mellitus (DM). However, the discrepancy between the number of organs needed and the number donated for transplantation is always enormous. Under a setting of scarce organ donations, we examined our limited experience of pancreas transplantation. METHODS: A retrospective review of pancreas transplantations was performed with the use of data from the Taiwan Organ Registry and Sharing Center and the Ministry of Health and Welfare. Pancreas transplantations in the Organ Transplantation Institute of Chang Gung Memorial Hospital also were reviewed. RESULTS: At present, there are 5 medical centers approved for pancreas transplantation in Taiwan. Overall, a total of 156 pancreas transplantations were performed from 2005 to the end of 2016; only 9 of them were performed in the Organ Transplantation Institute of Chang Gung Memorial Hospital. Although the number of organ donations is rising, pancreas transplantation numbers remain low. More than 20 pancreas transplantations were performed in 2016, yet there remained a total of 111 patients registered on the wait list for pancreas transplantation at the end of this study. Thus the gap between organ donation and transplantation is still vast. CONCLUSIONS: With continuing improvements in Taiwanese health policies and public education regarding organ transplantation, organ donation rates have risen steadily in recent years. Moreover, quality control and continuing evolution in organ transplantation is crucial to ameliorate the difficult situation of pancreas transplantation and other solid organ transplantation in the context of low levels of donation.

RESUMEN

BACKGROUND: The prognosis of patients after liver transplantation (LTx) with high Model of End-Stage Liver Disease (MELD) score (>30) is predicted, but patients with lower MELD scores (<30) have no conclusive studies of pre- and post-transplant risk factors that influence the long-term outcome. METHODS: This retrospective study reviewed 268 recipients with MELD score <30, from 2008 to 2013 in our institution, for evaluation of pre-transplant risk factors including patients' clinical background data, pre-transplant lymphocyte subpopulation, and early post-transplant infection complication as predictors for long-term survival after LTx. RESULTS: The post-transplant patients' survival estimates were 90.7%, 85.1%, and 83.6% at 1, 3, and 5 years, respectively. In multivariate analysis, age >55years, presence of ascites, cluster of differentiation (CD)3 < 93.2 (count/µL), CD4/CD8 <2.4, fungal infection, and more than one site of fungal colonization significantly influenced survival (P = .0003, P = .002, P = .04, P = .004, P < .0001, and P > .0001, respectively). We also noticed that these five factors accumulatively influence the long-term survival rate; this means that in the presence of any two risk factors, the 5-year survival can still be 88.4%, whereas in the presence of any three risk factors, the survival rate dropped to only 57.1%. CONCLUSIONS: Older patients in the presence of pre-transplant low immune cell number and ascites in association with post-transplant fungal infection are the independent risk factors in MELD scores <30 LTx groups for long-term survival. Patients in these groups with any of the three factors had inferior long-term survival results.

RESUMEN

BACKGROUND: Immunosuppression (IS) protocols should be individualized according to the individual recipient's immunity to minimize adverse effects. The aim of this study was to determine whether preoperative levels of CD8+ T lymphocytes could be used as a guide for the introduction of IS. METHODS: Sixteen adult liver transplantations in our institute were retrospectively analyzed. The immunosuppressive agents were temporarily withheld for 8 patients with a lower (<10%) preoperative percentage of CD8+ cells after transplant (classified as group A). In this group, postoperative immunosuppressive agents had never been used until acute rejection was suspected. Another 8 patients receiving classic IS were classified as group B. We collected their demographic features and analyzed the clinical courses. RESULTS: The postoperative IS-free period of group A was 5 to 120 days (median, 31 days). Our data showed an inverse correlation between CD8+ levels and the severity of liver disease. Although the IS-free protocol did not present a lower incidence of infection-related events, most of them were effectively treated with antibiotics. The 1-, 3-, and 5-year overall patient survival rates were not different between those with a short-term IS-free period and those with regular IS (87.5% vs 100%, 75% vs 100%, and 62.5% vs 87.5%; P = .468). No patient died of graft failure due to acute rejection. CONCLUSIONS: Postoperative immunosuppressive agents can be safely withheld for a period of time to preserve proper immune responses against infections in very sick recipients guided by using the CD8+ levels.

RESUMEN

AIMS: Surgical treatment for early-stage hepatocellular carcinoma (HCC) is toward transplantation. However, liver resection remains the major surgical treatment for HCC in Asia. This study is to examine the results of liver resection when liver transplantation became an option of treatment for early-stage HCC. METHODS: In this retrospective cohort study, 1639 patients with resectable HCC were reviewed and divided into two groups. In the 1st period (2002-2005), all 679 patients received liver resection. In the 2nd period (2006-2010), 916 patients had liver resection and 44 patients jointed liver transplantation program. The results of treatment in these two periods were analyzed. RESULTS: The characteristics of tumors were the most important factors of tumor recurrence after liver resection. Liver function reserve, characteristics of tumors, and surgeons' endeavor were all independent factors for overall survival after liver resection. When the patients with oligo-nodular tumors or portal hypertension with low platelet count had liver transplantation rather than liver resection in the 2nd period, the survival rates in the 2nd period were improved. When the patients in the 1st period with low platelet count (≤105 × 10(3)/uL) were subtracted, the 5-year survival rate of the patients with one-segmentectomy for small-sized HCC in the 1st period was similar to those in the 2nd period and transplant patients. CONCLUSIONS: The outcomes of liver resection were improved while liver transplantation was performed for the patients with suspicious portal hypertension. Platelet count, 105 × 10(3)/uL, could be a watershed for early stage HCC patients to undergo liver resection or liver transplantation.

RESUMEN

The purposes of this study were to determine if (a) the log-transformed model can be applied to dynamic exercise and (b) the slope and y-intercept terms can provide additional information above and beyond the polynomial regression analyses. Eleven physically active individuals performed incremental cycle ergometry on a single occasion. Electromyographic electrodes were placed on the three superficial quadriceps muscles to record muscle activation during the exercise test. The patterns of responses for electromyographic amplitude vs power output were analyzed with polynomial and log-transformed regression models. The results of the polynomial regression for the composite data indicated that the best-fit model for the vastus lateralis muscle was linear (R(2) = 0.648, P < 0.0001), whereas the best-fit model for the rectus femoris (R(2) = 0.346, P = 0.013) and vastus medialis (R(2) = 0.764,P = 0.020) muscles was quadratic. One-way repeated measures analyses indicated no significant differences(P > 0.05) across the three superficial quadriceps muscles for the slope and y-intercept terms. These findings suggest that the log-transformed model may be a more versatile statistical approach to examining neuromuscular responses during dynamic exercise.

RESUMEN

AIM: Periodontal disease encompasses gingivitis and periodontitis, which exerts systemic effects. We conducted a population-based study to evaluate the association between periodontal disease and the risk of cancer. METHODS: We used insurance claims data from 1997 to 2010, accessing a database of 1 million randomly selected insurants in Taiwan. All patients were older than 20 and newly diagnosed with periodontitis between 1 January 1997 and 31 December 2010. The comparison cohort comprised patients older than 20, who were newly diagnosed with gingivitis in the same period. Both cohorts were followed until a cancer diagnosis, lost to follow-up, death, termination of insurance, or the end of 2010. RESULTS: The incidence rate of cancer was 1.14 times higher in the study cohort than in the comparison cohort [confidence interval (CI) = 1.11-1.17]. The adjusted hazard ratio (HR) was 1.05 (95% CI = 1.00-1.11). A multivariable analysis showed that the periodontitis patients exhibited an elevated risk of developing oral cancer (adjusted HR = 1.79, 95% CI = 1.42-2.25). CONCLUSION: The findings indicated that patients in the periodontitis cohort exhibited a higher risk of developing oral cancer than those in the gingivitis cohort.

RESUMEN

A selective and differential medium termed 'LG agar' was developed for the isolation and presumptive identification of Lactococcus garvieae that results in black colonies with red halos. In this study, all 14 strains of L. garvieae and only 9 of the 148 strains representing 38 other species were able to grow on the LG agar. The nine viable strains on LG agar plates (including Enterococcus faecalis, Enterococcus faecium, Lactococcus lactis, Vibrio fluvialis, Vibrio furnissii, Vibrio mimicus and Vibrio salmonicida) were further differentiated from L. garvieae by various colours or colony features. Colonies isolated from the mixing culture and the infected giant sea perch using LG agar plates were all positively identified as L. garvieae by conventional tests and 16S rDNA sequencing. Furthermore, LG agar discriminated capsulated strains of L. garvieae, which were believed to be correlated with pathogens of fish and shellfish, from non-capsulated ones by colony appearances. The specificity and differentiating ability of LG agar suggest that this medium displays considerable potential for primary isolation and presumptive identification of L. garvieae from pathological and environmental samples.

RESUMEN

BACKGROUND: The modified piggyback technique with side-to-side cavocavostomy decreases the risk of outflow obstruction compared with the standard piggyback method. However, this modification is not ideal for recipients who receive a graft that is voluminous or bears an enlarged caudate lobe. METHODS: We modified the inferior vena cava (IVC) preservation technique against deleterious complications of compression by using a passing loop. CASE PRESENTATION: A 49-year-old woman, who underwent orthotopic liver transplantation for hepatic failure, was allocated a large-size liver. In anticipation of serious caval compression due to the voluminous grafts, we kept the suprahepatic or infrahepatic donor caval cuffs open for an anastomosis. The first anastomosis was performed between suprahepatic donor IVC cuff and recipient middle-left hepatic vein common channel; the second anastomosis was a terminolateral cavocavostomy between infrahepatic donor IVC cuff and the anterior wall of the recipient's IVC. DISCUSSION: When the liver circulation was restored, the donor retrohepatic vena cava served as a passing loop for both hepatic venous outflow and infra-diaphragmatic venous return to bypass possible IVC compression. Our technique may solve a dilemna for patients receiving voluminous liver grafts.

RESUMEN

BACKGROUND: This study evaluates the risk of benign brain tumors (BBTs) and malignant brain tumors (MBTs) associated with dental diagnostic X-ray, using a large population-based case-control study. MATERIALS AND METHODS: We identified 4123 BBT cases and 16 492 controls without BBT (study 1) and 197 MBT cases and 788 controls without MBT (study 2) from Taiwan National Health Insurance claim data. The risks of both types of tumor were estimated in association with the frequency of received dental diagnostic X-ray. RESULTS: The mean ages were ~44.2 years in study 1 and 40.6 years in study 2. Multivariable unconditional logistic regression analysis showed that the risk of BBT increases as the frequency of received dental diagnostic X-ray increases. The BBT odds ratio increased from 1.33 [95% confidence interval (CI) 1.22-1.44] for those with annual mean X-ray examination of less than one to 1.65 (95% CI 1.37-1.98) for those with three or more X-ray examinations, after controlling for comorbidities. No significant association was found between MBTs and dental diagnostic X-ray exposure. CONCLUSIONS: Exposure to dental diagnostic X-rays in oral and maxillofacial care increases the risk of BBTs, but not MBTs.

RESUMEN

BACKGROUND CONTEXT: Prognostic factors for curve progression of adolescent idiopathic scoliosis (AIS) have been reported previously. There is only one existing rule that classifies AIS patients into two groups by a curvature of 25°. PURPOSE: This study aimed to develop a more refined risk classification rule for AIS. STUDY DESIGN: This was a retrospective cohort study. PATIENT SAMPLE: We examined 2,308 untreated AIS patients, aged 10 years and older, who had a Risser sign of 2 and lesser and a curvature less than 30° at presentation. OUTCOME MEASURES: Outcome was taken as the time to progression to 30°. METHODS: Patients' clinical parameters were analyzed by Classification and Regression Tree analysis. RESULTS: The new classification rule identified four risk groups of curve progression. Patients with a curvature of 26° and more and less than 18° constituted the highest and lowest risk groups, respectively. The two intermediate groups were identified by the age (11.3 years), menarcheal status, and body height (154 cm). CONCLUSIONS: The risk classification rule only uses information at the first presentation and can aid physicians in deriving an efficient management.

RESUMEN

BACKGROUND: The liver is considered to be an immune-privileged organ. Several types of liver cells have been implicated in the induction of immunologic tolerance. Hepatic stellate cells (HSCs) seem to participate in hepatic fibrosis and to display immunological properties. MATERIALS AND RESULTS: In this study, HSCs isolated from C3H mice were highly positive for GFAP (98.4%) and α-SMA (95.4%). After stimulation by interferon-γ (IFN-γ), HSCs were more active in morphology with enhanced expression of H2-K(K), I-A(K), CD80, and CD54, similar to mature myelogenic dendritic cells (MDCs). Through allogeneic stimulation, C3H HSCs induced proliferation of both CD8(+) and CD4(+) T cells in B6 mice. However, the T cells activated by allogeneic HSCs produced less INF-γ, interleukin (IL)-4, IL-10, and IL-17, but large amount of transforming growth factor-ß. These T cells expressed immunoregulatory rather than effector functions. Naïve T cells stimulated by allogeneic HSCs expressed Foxp3 compared with MDCs (8.67% vs 2.14%, P < .05). CD8(+) T cells activated by HSCs lost their allogeneic cytotoxicity, and CD4(+) T cells activated in this fashion suppressed the allogeneic cytotoxicity of CD8(+) T cells activated by MDCs. CONCLUSION: HSCs seem to act as liver-resident antigen-presenting cells instructing the generation of Foxp3(+) regulatory T cells, a property suggestion of induction of immunologic tolerance.

RESUMEN

AIMS: To compare methods to measure time outdoor and light levels, two possible predictors of myopia, in Singapore children. METHODS: Outdoor time from a diary and portable light meter over a 1-week period was compared in 117 Singapore children aged 6-12 years with and without myopia. All children wore a (HOBO Pendant temp/light Part # UA-002-64) light meter for 1 week and the parents filled the 7-day outdoor diary to track the outdoor activity. RESULTS: Mean outdoor time from diary and time with light levels was 5.44 hours per week and 7.91 hours per week, respectively, during school term and school holidays. Time spent with light levels of >1000 Lux from the light meter were 7.08 h per week and 9.81 h per week, respectively, during school term and school holidays. The intraclass correlation coefficients were 0.21 and 0.28 for outdoor time from the diary and light meter (1000 Lux cut-off) during the school term and holidays, respectively. The correlation coefficient was 0.34 (95% CI 0.05, 0.58) for a weekday during school holidays, 0.17 (-0.14, 0.45) for a weekday during school term, 0.07 (-0.16, 0.29) for a weekday during school term, and 0.25 (0.02, 0.46) for a weekend during school term. CONCLUSIONS: The agreement between the light meter and 1-week diary was poor to fair. Both instruments measure different parameters, time outdoors and light intensity, and could therefore capture different aspects of risk in future myopia studies.
