RESUMO
AIMS: To delineate the clinical topography of peripherally inserted central catheter (PICC)-related thrombosis in cancer patients. BACKGROUND: Most of the clinical features of PICC-related thrombosis are based on a single follow-up, which is insufficient to reflect the full topography of a thrombosis. DESIGN: This is an observational study conducted at West China Hospital, according to the STROBE guidelines. METHODS: Cancer patients scheduled for PICC placement were potentially eligible; patients with contraindications to PICC placement or existing diseases affecting blood flow were excluded; and those who later withdrew or did not reply to our contact request during the follow-up period were eliminated from this study. Ultrasound was used to detect thrombosis from the insertion site, proximal insertion site, axillary vein to the subclavian vein once every two days for two weeks post insertion. The thrombosis and its involved venous segments, onset time and symptoms and signs were recorded. RESULTS: Among the 173 included patients, 126 (72.8 %) were identified as having thrombosis. Specifically, 113 and 126 patients were identified as having thrombosis within the first three days and the first week post insertion, respectively. In the 126 patients, thrombosis occurred at the insertion site (72.8 %) concurrently with thrombosis at the proximal insertion site (n = 120, 69.4 %), thrombosis in the axillary vein (n = 94, 54.3 %), and/or thrombosis in the subclavian vein (n = 41, 23.7 %). The log-rank test demonstrated that thrombosis in these four venous segments decreased significantly from the distal to the proximal central vein (log-rank test = 117.128, P < .001). Of 31 patients (17.9 %) who presented symptomatic thrombosis, only five patients experienced obvious swelling in the upper arm, and the other 26 patients exhibited atypical symptoms, such as soreness, tightness, numbness, tingling, or other discomforts in the palm, arm, armpit, and/or shoulder. In some thrombotic cases, ultrasonic assessment of PICC-related thrombosis did not parallel clinical symptoms and signs. CONCLUSION: PICC-related thrombosis is common and can occur very early post insertion in cancer patients, and most thromboses present atypical symptoms. More than half of the cases with thrombosis evaluated involve multiple venous segments, and the farther the venous segments are from the central vein, the higher the incidence of thrombosis tend to be and the earlier the onset time are. RELEVANCE TO CLINICAL PRACTICE: The results highlight the importance that medical staff pay particular attention to patients with catheters in the first week post insertion and be alert to thrombosis presenting atypical symptoms while keeping in mind that clinical symptoms and signs are not reliable for diagnosing thrombosis.

RESUMO
Background: Weight loss is an important side effect of long-term anticancer treatment for nasopharyngeal carcinoma patients. The decline in body function will cause many adverse effects, such as local recurrence and distant metastasis, and reduce the patient's quality of life. Therefore, this study developed a predictive model for the probability of critical weight loss to provide timely appropriate nutritional interventions and prevent serious side effects. Methods: A 20-week prospective follow-up study of 137 nasopharyngeal carcinoma patients in West China Hospital of Sichuan University undergoing radiotherapy and chemotherapy from February 2018 to March 2020 was conducted to collect relevant clinical data. The clinical usefulness and calibration of the prediction model were assessed using the C-index, calibration plot, receiver operating curve, and decision curve analysis. Internal validation was assessed using bootstrapping validation. Results: The nomogram consisted of sex, smoking status, physical status, chemotherapy regimen, and body mass index. Good calibration was observed for the cohort, with an area under the curve of 0.924. Five independent prognostic factors were included in the nomogram, which showed a high C-index value of 0.815 in the interval validation. Decision curve analysis showed that the nomogram was clinically useful when the intervention was decided at the critical weight loss possibility threshold in the 0% to 97% range. Conclusions: We constructed and validated a nomogram for predicting the incidence of critical weight loss in nasopharyngeal cancer patients undergoing chemotherapy and radiotherapy.
RESUMO
BACKGROUND: As a result of the one-child policy of 1979, today there are numerous one-child families with adolescents in Mainland China. Little is known about the experiences of parents of such adolescents diagnosed with cancer. OBJECTIVES: This study explored the experiences of parents whose adolescent child was diagnosed with cancer in one-child families in China. METHODS: A qualitative methodology based on hermeneutic phenomenology was employed. The participants were parents of adolescent cancer patients in one-child families. Data were collected using in-depth semi-structured interviews and analysed using van Manen's hermeneutic phenomenological approach. The COREQ checklist was used for this study. RESULTS: Fourteen parents (eleven mothers, three fathers) participated in the study. One overarching theme emerged: feeling like the sky is falling down. In addition, there were five related themes: self-condemnation; 'white lies' - that is, difficulty in telling the truth; struggling with a sense of collapse; fear of losing the child and hopelessness. Almost all the participants experienced insomnia after learning about the diagnosis. In a few cases, hopelessness-induced suicidal ideation or even suicidal behaviour. CONCLUSIONS: Parents of adolescents diagnosed with cancer in one-child families in China experienced extremely painful emotions. The truth about their child's condition not only caused immense psychological trauma but also induced pessimism about their own future. IMPLICATIONS FOR CLINICAL PRACTICE: The experiences of parents in one-child families where an adolescent child has been diagnosed with cancer should be taken seriously. In addition, support should be provided to help parents maintain a normal life and feel hopeful for their future.

OBJECTIVE: To investigate the effect of early home-based cardiac rehabilitation (CR) exercise on the prognosis of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). METHODS: The clinical data of 115 patients with AMI in our hospital were collected retrospectively. All patients underwent PCI and were divided into group A (n=57) and group B (n=58) according to postoperative intervention. Patients in group A only received routine rehabilitation guidance, while those in group B received early home-based CR exercise. The incidence of postoperative complications, cardiac function index, 6-minute walking distance (6MWD), cardiac antioxidant index, exercise endurance index and quality of life score were compared between the two groups before and after intervention. RESULTS: Compared with those in group B, patients in group A showed a lower incidence of postoperative complications (17.54% vs. 3.45%, P<0.05). After intervention, group A had lower left ventricular ejection fraction (LVEF), left ventricular end systolic diameter (LVESD) and left ventricular end diastolic diameter (LVEDD), longer 6MWD, higher total antioxidant capacity (T-AOC) and superoxide dismutase (SOD), lower malonaldehyde (MAD), higher exercise duration (ED), anaerobic threshold (AT) and VO2 and higher scores of quality of life than group B (P<0.05). CONCLUSION: Early home-based CR exercise in patients with AMI after PCI can improve cardiac function, reduce the incidence of postoperative complications as well as enhance cardiac antioxidant capacity, exercise ability and quality of life.
RESUMO
BACKGROUND: The negative synergistic effect of cancer and a peripherally inserted central catheter could significantly increase the incidence of thrombosis. Rather than identifying risk factors for peripherally inserted central catheter-related thrombosis, exploring the effect of these risk factors might be a promising method to improve the outcomes of thrombosis. OBJECTIVES: To analyze the effect of systemic and local risk factors on triggering peripherally inserted central catheter-related thrombosis in the first two weeks post-insertion in cancer patients. DESIGN: A prospective cohort study. SETTING: The study was conducted at a 4500-bed university-affiliated medical center in China. PARTICIPANTS: One hundred seventy-three cancer patients with peripherally inserted central catheters were included. METHODS: Peripherally inserted central catheter-related thrombosis was assessed using ultrasound at a series of timepoints, once every two days post-insertion. Data on age, body mass index, blood hypercoagulation, insertion attempts, catheter-to-vein ratio, and blood flow velocity were collected as risk factors. Descriptive statistics and structural equation modeling were used to describe the study samples and analyze the effects of systemic and local risk factors. RESULTS: Among the 173 cancer patients included, 126 (72.8%) patients were diagnosed with peripherally inserted central catheter-related thrombosis. Most thromboses (n = 118, 93.7%) were detected within five days, and 100% were detected within nine days post-insertion. Structural equation modeling analysis showed that local risk factors [catheter-to-vein ratio (standardized path coefficient = 0.32, p < 0.05) and blood flow velocity (standardized path coefficient = -0.35, p < 0.05)] had a greater effect than systemic factors [age (standardized path coefficient = 0.13, p < 0.05) and blood hypercoagulation (standardized path coefficient = 0.17, p < 0.05)] on triggering peripherally inserted central catheter-related thrombosis. CONCLUSION: Peripherally inserted central catheter-related thrombosis is quite common and can occur very early post-insertion in cancer patients. Among the common risk factors, local risk factors reflecting peripherally inserted central catheter technology itself had a greater effect than systemic risk factors reflecting predisposition to thrombosis.

OBJECTIVES: To analyze the weight change trajectory in patients with locally advanced nasopharyngeal carcinoma (LANPC) before, during, and after radiation therapy for a time span of 40 weeks. SAMPLE & SETTING: 147 patients from a university-affiliated medical center in China were included. METHODS & VARIABLES: Body weight was measured weekly during intensive treatment and biweekly after radiation therapy. RESULTS: All 147 patients experienced critical weight loss during the peri-radiation therapy period. Overall, body weight remained basically unchanged during induction chemotherapy, followed by a sharp and severe decrease during radiation therapy. At 20 weeks after radiation therapy, body weight had increased only slightly from the lowest point. IMPLICATIONS FOR NURSING: A time-tailored intervention based on the weight change trajectory is necessary for patients with LANPC. According to the weight change trajectory, relevant interventions for maintaining body weight should be initiated as early as the second week of radiation therapy and no later than the fourth week of radiation therapy, and these interventions should continue for at least four weeks after radiation therapy.
