A six-year study of complications related to peripherally inserted central catheters: A multi-center retrospective cohort study in China.

OBJECTIVE: Peripherally inserted central catheters (PICCs), the most frequent central venous catheter, are used to provide medical treatments, although long-term PICC-related adverse outcomes are unknown in China. This study systematically investigated PICC-related complications in four Chinese hospitals. METHODS: Between January 2014 and January 2020, we analyzed the results of 3550 patients with PICC who were referred to four Chinese hospitals. All patients underwent PICC treatment in four Chinese hospitals. Patient-reported signs and symptoms of a putative PICC-related complication or functional were studied. Long-term outcomes and hospitalization costs were also evaluated. RESULTS: An aggregate of 3285 patients were enrolled in the analytic cohort. 58.6% were females and 41.4% were males. The most common reasons for PICC placement included oncologic malignancy and critically ill patients. The majority of PICCs had valved systems (90.7%) and were implanted in the right side (85.5%) and into the basilic vein (87.7%). At least one potential PICC-related problem or adverse effects (AEs) was reported by 67.3% of patients. Central line-associated bloodstream infection (28.1%) and symptomatic deep vein thrombosis (20.7%) were the most common complications. The majority of PICCs were removed for causes other than AEs, with just 723 reported AEs accounting for 22.0% of all PICC removals. The most reasons for PICCs removal were occlusion (425, 12.9%) and exit-site infections (189, 5.8%). CONCLUSIONS: This study is the first retrospective study in our country to explore PICC-related complications. While living with a PICC, more than 67.3% of patients report signs and symptoms of at least one PICC-related problem or adverse impacts, such as difficulties with PICC use and poor effects on physical and social function. In this group, PICCs are safe and effective, although the danger of PICC-related problems should not be disregarded.

Effects of Atorvastatin Therapy on Postoperative Delirium After Malignant Tumor Surgeries in Older Adults.

Introduction: Postoperative delirium (POD) is one of the prevalent and potentially fatal clinical conditions, leading to high disability and mortality in older patients, as well as increased duration of hospital stay and more hospitalization expenses. There were no effective drugs in the clinical management of POD, and an absence of evidence-based medicine concerning the treatment of POD. Materials and Methods: The present study explored whether atorvastatin (Ato) can decrease the occurrence rate of POD. The present research included patients over the age of 60 who were hospitalized to critical care units (ICUs) following surgery for malignant tumors. Patients received Ato (40mg/day) or placebos utilizing a computer-based random sequencing (in a 1:1 ratio). The primary outcome measure was the occurrence of delirium within the first seven days following surgery. Results: A total of 230 individuals were classified into two groups, namely the placebo group (n=123) and the Ato group (n=107). Patients belonging to two groups had similar baseline clinical data, and there were no statistically significant differences between them. The occurrence of delirium in the Ato group was remarkably reduced unlike the case in the placebo group. 30-day all-cause mortality did not vary significantly between the two groups. Pulmonary infection and Bedsore were significantly decreased in the Ato group than the placebo group, there were no statistically significant differences between the two groups in rhabdomyolysis and abnormal liver enzymes. In terms of medication responses, there were no statistically significant differences between the two groups. Ato patients had remarkably shortened hospital stays and spent remarkably less on hospitalization expenditures in comparison with those in the placebo group. Conclusion: The findings from the present research indicated that Ato can decrease the occurrence of delirium following surgical operation of malignant tumors among elderly patients, it also can reduce the duration of hospitalization, hospital cost, and post-surgical complications, but not improve 30-day all-cause mortality.

Efficacy and safety profile of two-dose SARS-CoV-2 vaccines in cancer patients: An observational study in China.

BACKGROUND: The new coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has produced a global pandemic of coronavirus disease 2019 (COVID-19), resulting in modifications to public health policies on a universal scale. SARS-CoV-2 vaccine has evolved as the most effective and secure way for protecting healthy individuals against COVID-19. Patients with cancer were excluded from clinical trials due to their increased COVID-19 risk and current immunosuppressing therapy. Safety and effectiveness evidence is insufficient for SARS-CoV-2 vaccination in cancer patients. AIM: To assess the efficacy and safety of two-dose SARS-CoV-2 vaccines in cancer patients. METHODS: A multicenter observational study was performed at ten Chinese hospitals between January 1, 2021 and December 31, 2021. Each participant in the research received two doses of vaccination. A total of 215 healthy people were screened and 132 eligible patients with cancer were recruited. In order to verify the safety of the second dose of the vaccine, a side-effect report was compiled. Two weeks following the second vaccination dose, subjects underwent an analogous questionnaire survey. Utilizing a magnetic particle-based chemiluminescence immunoassay, serum levels of anti-SARS-CoV-2 immunoglobulin G (IgG) antibodies were measured to determine the effectiveness of vaccination. IgG levels ≥ 10 AU/mL were considered seropositive. RESULTS: All the 347 eligible patients completed the follow-up, and anti-SARS-CoV-2 IgG antibodies were detected. Local pain at the injection location was the most common side effect mentioned by all responders, with an increased incidence in cancer patients than the healthy people after the second dose vaccine (17.2% vs 9.1%; P = 0.035). There was no significant difference in headache, urticaria, or other adverse reactions between patients with cancer and healthy people. In the group of cancer patients, the seropositivity incidence was 83.3%, while it was 96.3% in the group of healthy people. In the group of cancer patients, the seropositivity incidence and antibody levels were significantly lower (P < 0.001). This analysis showed a poorer response rate in patients on active immunosuppressive treatment and elderly cancer patients. CONCLUSION: Two-dose Chinese vaccines are effective and safe in cancer patients. However, further research is required on the efficacy in elderly cancer patients and those on active immunosuppressive treatment.
