RESUMEN

The chemical constituents from the roots of Thalictrum cultratum and T. baicalense were investigated. By various isolation methods, such as silica gel, aluminium oxide, ODS, and Sephadex LH-20 column chromatographies, and semi-preparative HPLC, 11 simple isoquinoline alkaloids were isolated from the ethanol extract of the roots of these two plants, including a new compound, named dehydrothalflavine(1), and ten known ones(2-11): N-methylcorydaline(2), N-methylthalidaldine(3), thaliflavine(4), oxyhydrastinine(5), noroxyhydrastinine(6), dimethoxyisoquinolone(7), thalactamine(8), dehydronoroxyhydrastinine(9), 6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline(10), and isopicnarrhine(11). Their structures were elucidated on the basis of HR-ESI-MS and 1 D and 2 D NMR techniques. Compound 1 was a new isoquinoline alkaloid. Compound 11 was obtained from Tha-lictrum plant for the first time. All compounds did not show cytotoxic activities against HL-60, U937, HCT116, Caco-2, and HepG2 cancer cell lines.

RESUMEN

BACKGROUND: Hospice shared care is a model of care widely used in patients with terminal cancer. Appropriate interventions to improve related symptoms should be provided during disease progression through the end of life. PURPOSE: The purpose of this study was to explore the related symptoms and to compare symptom severity before and after the implementation of hospice shared care and medical care interventions. METHODS: Fifty patients with terminal cancer were enrolled in this longitudinal, quasi-experimental research. Inclusion criteria included having an expected life span of < 6 months and agreeing to enter hospice shared care. RESULTS: The three most-frequently noted physical symptoms were, in rank order: "pain", "weakness", and "dyspnea". In terms of severity, "pain" was the most severe, followed by "weakness" and "disturbance of sleep". The three most-frequently noted psychological symptoms were, in rank order: "depression", "worry about the disease", and "afraid of dragging others down". In terms of severity, "depression" was the most severe, followed by "anxiety" and "worry about the disease". The frequency and severity of the top-3 social and spiritual distress symptoms were, in rank order: "unfinished wish", "economic difficulties", and "painlessness". During the study period, the severity of physical symptoms improved gradually, while the severity of psychological symptoms improved significantly. The top-3 items in the original medical team`s hospice-care interventions were, in rank order: "tube care", "laboratory test", and "wound care" in the non-pharmacological category; "symptom control medication", "antibiotic injection", and "intravenous fluid infusion" in the pharmacological category; and "cognitive clarification of the prognosis condition", "do not conduct resuscitation discussions and signing", and "emotional stress consoling" in the problem-coordination and interview categories. The interventions implemented by the hospice specialist team included "emotional stress interview", "team communication", and "cognitive clarification of prognosis condition" in the problem coordination and interview categories, and "massage", "consultation", and "nursing advice" in the non-pharmacological category. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The symptoms identified in this study provide clinical staff with a reference for the rapid assessment of patients with terminal-stage cancer. Manpower from various professional fields are committed to providing diversified services in the care teams, which positively affect the control of related symptoms. The experience presented in this article may be used as a reference to promote the hospice shared care model.

RESUMEN

PURPOSE: The aims of this study were to identify the factors and reasons impacting discordance with the treatment plan in head and neck cancer (HNC) patients and compare the differences between the concordance group and the discordance group. METHODS: This secondary analysis was conducted from population-based data from Taiwan collected from January 1, 2016, to June 30, 2018. Logistic regression analysis was used to identify the factors related to discordance with the treatment plan. RESULTS: We examined 1095 HNC patients, 12.1% of whom were discordant with treatment. Patients with advanced cancer stage, old age, and treatment plans of best supportive care (BSC) or surgery combined with radiation (RT), chemotherapy (CT), or chemoradiation (CCRT) were more likely to have discordance with their treatment plan. Of the 133 patients who were discordant with their treatment plan, the top reasons were as follows: "patients or their family considered patients' poor physical condition (chronic disease or unstable systemic disease), difficulty in enduring any condition likely to cause physical discomfort from disease treatment," "inconvenient transportation," and "disease progression." CONCLUSIONS: Patients' cancer stage, age, and types of treatment plans recommended significantly influenced discordance with treatment plan. Poor physical condition was the major reason for discordance with the treatment plan. Patients in the concordance group were significantly more likely than those in the discordance group to be younger than 65 years, have less advanced cancer stage, and be recommended to receive surgery rather than any other regimen. Multidisciplinary team care can help patients make positive decisions about treatment.

RESUMEN

AIMS: To: (a) explore the prevalence of the symptoms perceived by patients with childhood-onset systemic lupus erythematosus; (b) identify the symptom clusters occurring in patients with childhood-onset Systemic lupus erythematosus; and (c) examine the association of the burden of each symptom cluster with sleep quality and depression. BACKGROUND: Systemic lupus erythematosus is an inflammatory autoimmune disease that may result in patients' perception of various symptoms, with possible negative effects on their quality of life. Understanding the prevalence of symptoms perceived by childhood-onset Systemic lupus erythematosus patients and the disease's symptom clusters may be helpful in managing such burdensome symptoms. DESIGN: A correlational study design was used for this study in 2016. METHODS: Self-reported data from the Systemic lupus erythematosus symptom checklist were used to assess the symptoms perceived by patients. Symptom clusters were analysed using cluster analysis. RESULTS: Seventy-five patients were included in this study. The most prevalent and burdensome symptom perceived by patients was fatigue. Five clusters were derived, including symptoms related to pain and itching; bruises and stomach complaints; weight gain; body image and circulatory problems; and fatigue. A poor sleeper may perceive a greater symptom burden in all five of the symptom clusters, except for cluster #3, which refers to symptoms related to weight gain. CONCLUSION: Five symptom clusters were identified. It is hoped that this study will give useful knowledge for understanding the symptom clusters for patients with Systemic lupus erythematosus and for improving nursing care quality.

RESUMEN

Heart failure is a complicated chronic disease. Although numerous new medications are used to treat and improve the quality of life of patients with heart failure, the final treatment for terminal heart failure still relies heavily on heart transplants. However, as the number of heart donations is limited, many health institutions implant mechanical assist devices to perform heart functions temporarily. These implanted ventricular assist devices help reduce heart failure symptoms and enhance quality of life. However, driveline infection is one of the more severe complications associated with these devices. If this infection is not controlled, another heart surgery will be necessary to replace the device. Severe driveline infection may even lead to patient death. An approach to care that includes driveline wound care standardization and immobilization of the driveline has been shown to effectively decrease the incidence of driveline infections and to increase the survival rate. As Taiwan still lacks the relevant clinical care standards for implantable ventricular assist device support and driveline wound care, this study introduces the relevant Western literature and the author's clinical experience related to driveline wound management. We hope that this article serves as a useful reference for related nursing care.

RESUMEN

AIMS: The purposes of this study were to identify the impact of a case management programme on the related factors of refusing treatment or discontinuing treatment in Taiwanese colorectal cancer patients. BACKGROUND: Side effects of anti-cancer treatments are associated with refusing treatment and discontinuing treatment. DESIGN: This case-control study, longitudinal database and secondary analysis of population-based data was conducted from 2009-2012. METHODS: Logistic regression was used to reveal the factors related to refusing or discontinuing treatment. RESULTS: Of the 68 patients who refused treatment, the top reasons for refusing treatment were patients or their family considered the patients poor physical condition, difficulty in enduring any condition likely to cause physical discomfort from the disease treatment, selected complementary and alternative medicine, patients or their families or friends experienced negative treatment effects and worried about the side effects of treatment, older age, poor family support and lost contact. Of the 278 patients who discontinued treatment, the most common reasons for discontinuing treatment were patients or their families or friends experienced negative treatment effects and worried about the side effects of treatment, inconvenient transportation, patients or their family considered the patients poor physical condition, difficulty in enduring any condition likely to cause physical discomfort from the disease treatment, poor treatment effect and selected complementary and alternative medicine. CONCLUSION: Case managers can provide positive communication and available resources in relation to cancer treatment. A case management programme can help patients cope with the difficulties encountered during the treatment period.

RESUMEN

BACKGROUND: Withdrawal of mechanical ventilation is an important, but rarely explored issue in Asia during end-of-life care. This study aimed to describe the clinical characteristics and survival outcomes of terminally ill patients undergoing withdrawal of mechanical ventilation in Taiwan. METHODS: One-hundred-thirty-five terminally ill patients who had mechanical ventilation withdrawn between 2013 and 2016, from a medical center in Taiwan, were enrolled. Patients' clinical characteristics and survival outcomes after withdrawal of mechanical ventilation were analyzed. RESULTS: The three most common diagnoses were organic brain lesion, advanced cancer, and newborn sequelae. The initiator of the withdrawal process was family, medical personnel, and patient him/herself. The median survival time was 45 min (95% confidence interval, 33-57 min) after the withdrawal of mechanical ventilation, and 102 patients (75.6%) died within one day after extubation. The median time from diagnosis of disease to receiving life-sustaining treatment and artificial ventilation support, receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting," "Withdrawal meeting" to ventilator withdrawn, and ventilator withdrawn to death was 12.1 months, 19 days, 1 day, and 0 days, respectively. Patients with a diagnosis of advanced cancer and withdrawal initiation by the patients themselves had a significantly shorter time interval between receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting" compared to those with non-cancer diseases and withdrawal initiation by family or medical personnel. CONCLUSION: This study is the first observational study to describe the patients' characteristics and elaborate on the survival outcome of withdrawal of mechanical ventilation in patients who are terminally ill in an Asian population. Understanding the clinical characteristics and survival outcomes of mechanical ventilation withdrawal might help medical personnel provide appropriate end-of-life care and help patients/families decide about the withdrawal process earlier.

RESUMEN

AIMS AND OBJECTIVES: To (i) investigate the characteristics of health-related quality of life and satisfaction with case management and (ii) to identify factors associated with health-related quality of life in cancer survivors. BACKGROUND: The level of health-related quality of life can reflect treatment efficacy and satisfaction with cancer care. DESIGN: A cross-sectional study design was adopted. METHODS: Subjects from the outpatient setting of a cancer centre in northern Taiwan were recruited by consecutive sampling. A set of questionnaires were employed, including a background information form, case management service satisfaction survey (CMSS) and The European Quality of Life Scale (EQ-5D). Descriptive statistics were used to examine levels of health-related quality of life and satisfaction with case management. Pearson's correlation was used to identify relationships between treatment characteristics, satisfaction with case management and health-related quality of life. Multiple stepwise regression was used to identify factors associated with health-related quality of life. RESULTS: A total of 252 cancer patients were recruited. The three lowest scores for items of health-related quality of life were mobility, self-care and usual activities. Cancer survivors with higher mobility, less pain and discomfort, and lower anxiety and depression were more likely to have better health-related quality of life. CONCLUSION: Mobility, pain and discomfort, and anxiety and depression are important predictive factors of high health-related quality of life in cancer survivors. RELEVANCE TO CLINICAL PRACTICE: In clinical care, patients' physical mobility, pain and discomfort, and anxiety and depression are important indicators of health-related quality of life. Case managers should include self-care and symptom management into survivorship care plans to improve health-related quality of life during survival after treatment concludes.

RESUMEN

As many as 50% of end-stage cancer patients will develop ascites and associated symptoms, including pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, dyspnea, perceived abdominal bloating, and immobility. Abdominal massage may stimulate lymph return to the venous system and reduce ascites-related symptoms. The purpose of this study was to test the effect of abdominal massage in reducing these symptoms and reducing ascites itself as reflected in body weight. For a randomized controlled design using repeated measures, a sample of 80 patients with malignant ascites was recruited from gastroenterology and oncology units of a medical center in northern Taiwan and randomly assigned to the intervention or the control group. A 15-minute gentle abdominal massage, using straight rubbing, point rubbing, and kneading, was administered twice daily for 3 days. The control group received a twice-daily 15-minute social interaction contact with the same nurse. Symptoms and body weight were measured in the morning for 4 consecutive days from pre- to post-test. In generalized estimation equation modeling, a significant group-by-time interaction on depression, anxiety, poor wellbeing, and perceived abdominal bloating, indicated that abdominal massage improved these four symptoms, with the greatest effect on perceived bloating. The intervention had no effect on pain, tiredness, nausea, drowsiness, poor appetite, shortness of breath, mobility limitation, or body weight. Abdominal massage appears useful for managing selected symptoms of malignant ascites.

RESUMEN

BACKGROUND/PURPOSE: Breast cancer patients may encounter a wide range of physical and psychosocial distress symptoms during diagnosis, while awaiting treatment, and during treatment. This study of newly diagnosed breast cancer patients explores: (1) changes in symptom distress over 4 months; and (2) factors predicting changes in symptom distress. METHODS: A prospective longitudinal design was used to collect data from breast cancer patients in northern Taiwan. A set of questionnaires was used to measure anxiety, symptom distress, social support, and demographic and treatment-related characteristics. Repeated measures analysis of variance (RM-ANOVA) with least significant difference (LSD) was used to examine differences in symptom distress, state anxiety, and social-support levels across four time-points. Generalized estimating equation (GEE) is used to determine predictors for the change in symptom distress. RESULTS: Participants showed mild overall symptom distress during treatment that increased from cancer diagnosis to treatment phases, with a peak at 4 months after diagnosis. Insomnia was the most commonly identified distressful symptom over time. Changes in overall symptom distress were significantly predicted by state anxiety, health professional support, and time since cancer diagnosis. CONCLUSION: Change in symptom distress following the first 4 months after diagnosis was predicted by state anxiety, health professional support, and time. Patients should receive social support and be trained in problem-solving skills to relieve distressful symptoms from diagnosis through treatment.

RESUMEN

BACKGROUND: Dysphagia is a leading cause of aspiration pneumonia and negatively affects tolerance of chemoradiotherapy in patients with esophageal cancer. OBJECTIVE: This study aimed to assess a protocol for preventing the occurrence of aspiration pneumonia for adult patients with esophageal cancer experiencing swallowing dysfunction. METHODS: This study tested a dysphagia intervention that included high-risk patients confirmed by the Eating Assessment Tool questionnaire and Water Swallowing Test. A protocol guide (Interventions for Esophageal Dysphagia [IED]) to prevent aspiration pneumonia during chemoradiotherapy was also implemented. Thirty participants were randomly assigned to an intervention or control group. The study period was 50 days; participants were visited every 7 days for a total of 7 times. Instruments for data collection included The Eating Assessment Tool, Water Swallowing Test, and personal information. The IED was administered only to the experimental group. All data were managed using IBM SPSS statistics version 21.0. RESULTS: The IED significantly reduced the occurrence of aspiration pneumonia (P = .012), delayed the onset of aspiration pneumonia (P = .005), and extended the survival time (P = .007) in the experimental group. CONCLUSION: For patients with esophageal cancer undergoing chemoradiotherapy, this protocol improved swallowing dysfunction and reduced aspiration pneumonia. IMPLICATION FOR PRACTICE: The IED protocol should be included in continuous educational training for clinical nurses to help them become familiar with these interventions and to provide these strategies to patients.

RESUMEN

Purpose: Abnormal methylation of Grainyhead-like 2 (GRHL2) is associated with a substantial role in the malignant phenotype of tumor patients. Our present research is aimed at studying the abnormal expression of GRHL2 and the association of methylation in patients with acute leukemia and its relationship with prognosis. Materials and Methods: We used quantitative real-time polymerase chain reaction (qRT-PCR) for detecting the aberrant expression level of GRHL2 in 60 patients with acute leukemia and 60 normal controls. We analyzed the significant correlation between the expression level of GRHL2 with clinicopathological features and patients' prognosis in acute leukemia using the corresponding statistical methods. Secondly, we employed qRT-PCR and Western blotting to detect the mRNA and protein levels of GRHL2 in leukemia cell lines. Next, we used methylation-specific polymerase chain reaction (MSP) technology for detecting the methylation of GRHL2 in clinical samples with acute leukemia and cell lines. Then we investigated the demethylating effect of arsenic trioxide and 5-azacitidine on the mRNA and protein expression levels of GRHL2 in cell lines of acute leukemia. Finally, we studied the effects of arsenide trioxide and 5-azacitidine on the proliferation of leukemia cells and the TGF-ß signaling pathway. Results: We found a lower level of GRHL2 expression not only in acute leukemia patients but also in cell lines when compared with normal controls. At the same time, the expression level of GRHL2 in patients with acute leukemia was significantly correlated with leukocyte count, platelet count, and cytogenetic risk grouping. In addition, the lower GRHL2 expression group showed a significantly lower overall survival rate in acute leukemia patients than that of patients with a higher GRHL2 expression group. Univariate and multivariate analyses revealed that the expression of GRHL2 is an independent risk factor in acute leukemia patients. The methylation level of the GRHL2 promoter region in acute leukemia patients and cell lines was significantly higher than the normal control group, and we found the elevated mRNA and protein levels of GRHL2 in acute leukemia cell lines after the use of the demethylation drug arsenic trioxide and 5-azacitidine. At the same time, arsenide trioxide and 5-azacitidine are associated with the inhibition of cellular proliferation of acute leukemia cells and also promote the elevated expression of TGF-ß signaling pathway-linked proteins, including TGF-ß, Smad2, Smad3, and Smad4. Conclusion: Increased expression and methylation level of GRHL2 are closely associated with the prognosis and malignant phenotype of acute leukemia patients and play an irreplaceable role in the occurrence and development of patients with acute leukemia.

RESUMEN

This research focused on a novel 7-azaisoindigo derivative [namely N(1)-(n-butyl)-7-azaisoindigo, 7-AI-b], and investigated its molecular antitumor mechanism by exploring the means of cell death and the effects on mitochondrial function. 7-AI-b inhibited cancer cell proliferation in a dose- and time-dependent way. The morphological and nuclei changes in H(2) B-GFP-labeled HeLa cells were observed using a live cell system. The results suggested that cell death induced by 7-AI-b is closely related to apoptosis. 7-AI-b induced release of cytochrome C from mitochondria to cytosol and activation of caspase-3, showing that the apoptosis is mediated by the mitochondrial pathway. Furthermore, our data indicated that 7-AI-b triggers apoptosis through reactive oxygen species (ROS): cellular ROS levels were increased after 3 h exposure of 7-AI-b, which was reversed by the ROS scavenger N-acetyl-L-cysteine. As a consequence, 7-AI-b-mediated cell death, mitochondrial transmembrane potential collapse and ATP level were partly blocked by N-acetyl-L-cysteine. Further study showed that 7-AI-b could induce mitochondrial dysfunction: collapse of the mitochondrial transmembrane potential and reduction of intracellular ATP level. In summary, the novel synthesized 7-AI-b was demonstrated to be effective in killing cancer cells via an ROS-promoted and mitochondria- and caspase-dependent apoptotic pathway.

RESUMEN

BACKGROUND: Netrin-1 is an axon guidance protein, which can inhibit inflammatory reaction and stabilize the blood-brain barrier to protect against experimental brain injury. We evaluated the concentration of netrin-1 in acute intracerebral hemorrhage (ICH) patients and explored whether netrin-1 is a potential prognostic biomarker for ICH. METHODS: This study recruited a total of 126 ICH patients and 126 healthy controls. Netrin-1 concentration was determined using a commercially available human enzyme-linked immune sorbent assay kit. National Institutes of Health Stroke Scale (NIHSS) score and hematoma volume were used to assess hemorrhagic severity. An unfavorable outcome was defined as modified Rankin Scale >2 at 90 days. RESULTS: ICH patients showed significantly lower serum netrin-1 concentrations than controls. Serum netrin-1 concentrations were strongly and inversely correlated with serum C-reactive protein concentrations, NIHSS score and hematoma volume. Multivariate analyses revealed that low netrin-1 concentration was associated with 90-day death, unfavorable outcome and overall survival after adjustment for other confounding variables. Under the receiver operating characteristic curve, serum netrin-1 remarkably discriminated patients at risk of 90-day death and unfavorable outcome. CONCLUSIONS: Serum netrin-1 concentrations are decreased in patients with ICH, and the concentrations of netrin-1 were intimately associated with inflammation, hemorrhagic severity and clinical outcome of ICH.

RESUMEN

PURPOSE: Breast cancer patients who undergo docetaxel-based chemotherapy regimens can have hand-foot syndrome (HFS), which negatively impacts their ability to perform daily activities. The purpose of the study was to assess, in breast cancer patients receiving chemotherapy: the perceived levels of HFS-related symptoms of the feet, hands or fingers; and HFS-related restrictions in daily activities; as well as to identify factors associated with these symptoms and restrictions. METHODS: This cross-sectional study examined breast cancer patients who received docetaxel-based chemotherapy from the general surgery outpatient department and oncology outpatient department of a medical center in northern Taiwan. A set of structured questionnaires were used to measure patients' HFS-related symptoms and HFS-related restrictions in daily activities. RESULTS: Of the 85 breast cancer patients studied, 41.2% reported HFS. Patients had higher level of HFS-related foot symptoms than HFS-related hand or fingers symptoms. Greater restriction in HFS-related daily activities was associated with more HFS-related hand or fingers symptoms and more HFS-related foot symptoms; these factors explained 44.7% of the variance in restriction of activities. CONCLUSION: Skin care and patient education should be provided to manage the HFS of breast cancer patients receiving chemotherapy.

RESUMEN

BACKGROUND: Our purpose is to introduce transforaminal en bloc resection for the treatment of thoracic ossification of ligamentum flavum, and report outcomes of the procedure. PATIENTS AND METHODS: The record of patients with symptomatic thoracic ossification of the ligamentum flavum who received transforaminal en block resection from October 2010 to September 2014 were retrospectively reviewed. Outcomes were Japanese Orthopaedic Association (JOA) lower extremity motor dysfunction and sphincter dysfunction scores. RESULTS: Seventeen patients (10 males, 7 females) with a median age of 60 years were included in the analysis. Surgery was performed as planned without complications in all patients. One segment decompression was performed in 1 case, 2 segment in 9 cases, 3 segment in 3 cases, and 4 segment in 4 cases. The median lower extremity motor dysfunction score was significantly higher at 2 weeks, 3 months, and 6 months postoperatively, and the end of follow-up, than before surgery (median score: 2, 2, 3, 3, respective, vs. 1, all, p ≤ 0.008). There were no significant differences in JOA sphincter dysfunction score between the different time points. CONCLUSION: Transforaminal en bloc resection is a safe and effective method for the treatment of thoracic ossification of the ligamentum flavum.

RESUMEN

BACKGROUND: Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. METHODS: A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. RESULTS: The percentages of patient populations aged <40 years, 40-49 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years were 9.7%, 17.7%, 27.8%, 22.1%, 16.9%, and 5.7%, respectively. The median follow-up period was 38.9 months (range, 22.8-60.4 months) and the overall, cancer-specific, and noncancer-specific mortality rates were 26.0%, 17.6%, and 8.5%, respectively. The overall mortality rate of patients in different age groups were 18.5%, 21.1%, 22.0%, 25.3%, 35.3%, and 49.0%, respectively. Compared to patients aged <40 years, more significant decrease in long-term survival were observed in aging patients. Multivariate analysis showed higher postoperative short-term mortality rates in patients older than 70 years, and the adjusted odds ratio of mortality risk ranged from 1.47 to 1.74 and 2.26 to 3.03 in patients aged 70-79 years and ≥80 years, respectively, compared to those aged <40 years. CONCLUSION: Aging was a negative prognostic factor of survival outcome in solid cancer patients receiving curative surgery. After adjustment of other clinicopathologic factors, the influence of age on survival outcome was less apparent in the elderly.

RESUMEN

PURPOSE: Data on end-of-life care practices in Asia are scarce. This study aimed to analyze the clinical factors associated with the recommended premedication protocol for mechanical ventilation withdrawal, in Taiwan. METHODS: A total of 135 terminally ill patients who had mechanical ventilation withdrawn between 2013 and 2016 from a single medical center in Taiwan were enrolled. A premedication protocol of morphine and midazolam intravenous bolus was routinely recommended for the patients before mechanical ventilation withdrawal. Receipt of opioids and/or benzodiazepines during the withdrawal process was defined as full (both), partial (1 drug), and no (none) adherence. The clinical factors relevant to the adherence of recommended premedication protocol for mechanical ventilation withdrawal were analyzed. RESULTS: Overall, 126 (93.3%) patients died, 8 (5.9%) patients were transferred to other institutions for further care, and 1 (0.7%) patient was discharged to home after mechanical ventilation withdrawal. The median survival time was 45 minutes, and 102 (75.6%) patients died within 1 day after the withdrawal process. The full, partial, and no adherence rates for premedication guideline were 17.8%, 40.0%, and 42.2%, respectively. The main diagnosis of cancer, receipt of hospice care, and preservation of spontaneous respiration were independent variables associated with the partial or full adherence to the premedication protocol. CONCLUSION: Our data show that adherence to the premedication protocol for mechanical ventilation withdrawal in terminally ill patients was inadequate in Taiwan. Promoting hospice care and educating medical personnel in the compassionate withdrawal of mechanical ventilation, especially in patients with noncancer disease, are warranted.

RESUMEN

The purpose of this qualitative study is to understand mothers' experiences and perspectives concerning neonatal death.?In-depth interviews with eight mothers were conducted. Data were collected using a retrospective method based on semi-structured interview guidance, and analyzed according to Colaizzi's (1978) phenomenology approach. Four themes evolved: (1) Puzzlement on the brink of neonatal death: neonatal death, as an unpredicted event, constitutes a puzzle for mothers; they tend to seek the cause of the mishap, and in turn, fall into a dilemma about whether to try to save the newborn. (2) Chaos in the wake of the loss of babies: mothers' experience of physical, mental, and behavioral changes which might stymie their original positive attitude toward the role of being a mother, and further cause a divergence of expectations between the husband and wife. (3) Adjustments in the wake of the loss: when mothers try to adjust themselves, common approaches, such as good-will pep-talk and emotional utterance/sharing, are not really helpful. Certain factors also play a part, ether positively or negatively, in the mental adjustment process; they include responsibility for the household, intentional mood-diversion, prohibiting the mother from participating in funerals for the babies. (4) Professional guidance: mothers expect to receive professional guidance to help them to face the fact of death, especially in the moment of separation; providing memorabilia and personalized follow-ups for mothers are beneficial. In conclusion, it is suggested that mothers experiencing neonatal death should be encouraged to express their grief through appropriate emotional channels, and receive professional follow-up to rebuild physiologically, psychologically, and spiritually, rather than suppressing their mourning.

RESUMEN

Purpose/Aim of the study: The purpose of this analysis was to compare the clinical outcomes of vertebral fusion with allograft versus autograft bone. MATERIALS AND METHODS: Medline, PubMed, Cochrane, EMBASE, and Google Scholar databases were searched until July 27, 2015 using the keywords: lumbar vertebrae, surgery, spondylolisthesis, bone transplantation, allograft, autograft. Inclusion criteria were randomized controlled trials (RCTs), two-arm prospective studies, retrospective studies, and cohort studies comparing the results of autograft and allograft in patients receiving lumbar spinal fusion. The outcomes were changes of Oswestry Disability Index (ODI) and visual analogue scale (VAS) pain scores from baseline at 1, 2, and 3 years after surgery and fusion rates. RESULTS: Of 154 studies identified in the database searches, five were included in the quantitative analysis (one RCT, one prospective, and three retrospective studies). The mean patient age ranged from approximately 40 to 65 years, and approximately half of the patients were males. The total number of patients who received allografts was 333 and the total that received autografts was 175. The analysis revealed the change of ODI and VAS pain score at 1, 2 and 3 years was similar between the allograft and autograft groups (all, p > .05), as were the fusion rates (p > .05). CONCLUSIONS: Both allograft and autograft provide acceptable outcomes for spinal fusion.
