Assessment of folate status among women of childbearing age from 2000 to 2020 / 中华预防医学杂志

Objective: To analyze the folate status among women of childbearing age worldwide from 2000 to 2020, and explore the impact of socioeconomic factors on folate status, so as to provide support for the formulation of relevant supplementary policies in China in the future. Methods: The "folate" "folic acid" "deficiency" "status" "women" "childbearing" and "reproductive" were used as Chinese and English keywords to systematically search CNKI and PubMed database. Global Health Data Exchange database (GDHx), Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia datasets (BRINDA) and Ground Work publications were systematically searched with "micronutrients" and "nutrition" as keywords. The retrieval time was from January 1, 2000 to August 31, 2020, and the language was restricted to English and Chinese. After title, abstract and full-text screening, a total of 45 literatures were included. The folate status of women of childbearing age in the eligible literature was analyzed, and the income and folate status were tested by Kruskal Wallis H test and Nemenyi test. Results: The M (Q1, Q3) of serum folate deficiency rate and erythrocyte folate insufficiency rate in women of childbearing age were 15.0% (3.5%, 37.0%) and 49.0% (22.0%, 83.0%). There were great differences in serum folate status and serum folate deficiency rate among women of childbearing age in different income countries. The serum folate deficiency rate of women of childbearing age in low-income countries was significantly higher than that in middle and high-income countries. Conclusion: The folate status of women of childbearing age in most countries has not reached the ideal state from 2000 to 2020. More studies on folate supplementation programs should be carried out.

Analysis of nosocomial infection after intermediate-high dose cytarabine consolidation theraphy in patients with acute myeloid leukemia / 肿瘤研究与临床

Objective:To investigate the clinical characteristics, influencing factors and prevention and treatment measures of nosocomial infection in patients with acute myeloid leukemia (AML) (non-acute promyelocytic leukemia) after applying intermediate-high dose cytarabine (Ara-C) chemotherapy.Methods:The clinical data of 80 patients with AML treated with intermediate-high dose Ara-C in the Second Hospital of Shanxi Medical University from March 2013 to January 2020 were analyzed retrospectively. The clinical features of nosocomial infection were summarized and the influencing factors of infection were analyzed by using multivariate logistic regression.Results:A total of 80 patients received 198 times of chemotherapy, and the infection rate was 72.7% (144/198). Infection sites mainly included respiratory tract infection, pulmonary infection, gastrointestinal infection. A total of 45 strains of pathogenic bacterias were detected, among which Gram negative bacilli accounted for 55.6% (25/45), Gram positive cocci accounted for 24.4% (11/45), fungi accounted for 8.9% (4/45) and viruses accounted for 11.1% (5/45). There were no significant differences in infection rate, hospitalization time, neutrophils recovery time and hospitalization expenses between the sterile laminar flow ward and the general ward (all P > 0.05). Multivariate logistic regression analysis showed that infection during induction chemotherapy was independent risk factor of infection ( OR = 5.076, 95% CI 1.978-13.022, P =0.001), and antibiotic prevention was independent protective factor of nosocomial infection ( OR = 0.332, 95% CI 0.136-0.803, P = 0.014). Conclusions:The infection rate of AML patients receiving intermediate-high dose Ara-C chemotherapy is high. During the treatment, we should be alert to the infection during induction chemotherapy and use antibiotics to prevent it in time. For patients undergoing intermediate-high dose Ara-C chemotherapy, strengthening the environmental cleanliness of general wards may achieve the same preventive effect as that of sterile laminar flow wards.

Maintenance of pegylated liposomal doxorubicin/carboplatin in patients with advanced ovarian cancer: randomized study of an Asian Gynecologic Oncology Group / 부인종양

Objectives@#An Asian Gynecologic Oncology Group phase III randomized trial was conducted to determine whether maintenance chemotherapy could improve progression-free survival (PFS) in stages III/IV ovarian cancer. @*Methods@#Between 2007 and 2014, 45 newly-diagnosed ovarian cancer patients were enrolled after complete remission and randomized (1:1) to arm A (4-weekly carboplatin area under the curve 4 and pegylated liposomal doxorubicin [PLD] 30 mg/m2, n=24) for 6 cycles or arm B (observation, n=21). The primary end-point was PFS. A post hoc translational study was conducted to deep sequence BRCA/homologous recombination deficiency (HRD) genes, because BRCA/HRD mutations (BRCA/HRDm) are known to be associated with better prognosis. @*Results@#Enrollment was slow, accrual was closed when 7+ years had passed. With a medianfollow-up of 88.9 months, the median PFS was significantly better in arm A (55.5 months) than arm B (9.2 months) (hazard ratio [HR]=0.40; 95% confidence interval [CI]=0.19–0.87; p=0.020), yet the median overall survival was not significantly different in arm A (not reached) than arm B (95.1 months) (p=0.148). Overall grade 3/4 adverse events were more frequent in arm A than arm B (60.9% vs 0.0%) (p<0.001). Quality of life was generally not significantly different. Distribution of BRCA1/2m or BRCA/HRDm was not significantly biased between the two arms. Wild-type BRCAon-HRD subgroup seemed to fare better with maintenance therapy (HR=0.35; 95% CI=0.11–1.18; p=0.091). @*Conclusions@#Despite limitations in small sample size, it suggests that maintenance carboplatin-PLD chemotherapy could improve PFS in advanced ovarian cancer.

Heart Rate Variability Biofeedback Increased Autonomic Activation and Improved Symptoms of Depression and Insomnia among Patients with Major Depression Disorder

OBJECTIVE: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. METHODS: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. RESULTS: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. CONCLUSION: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

A longitudinal analysis with CA-125 to predict overall survival in patients with ovarian cancer / 부인종양

OBJECTIVE: The objective of this study was to explore the association of longitudinal CA-125 measurements with overall survival (OS) time by developing a flexible model for patient-specific CA-125 profiles, and to provide a simple and reliable prediction of OS. METHODS: A retrospective study was performed on 275 patients with ovarian cancer who underwent at least one cycle of primary chemotherapy in our institute. Serial measurements of patients' CA-125 levels were performed at different frequencies according to their clinical plans. A statistical model coupling the Cox proportional hazards and the mixed-effects models was applied to determine the association of OS with patient-specific longitudinal CA-125 values. Stage and residual tumor size were additional variables included in the analysis. RESULTS: A total of 1,601 values of CA-125 were included. Longitudinal CA-125 levels, stage, and the residual tumor size were all significantly associated with OS. A patient-specific survival probability could be calculated. Validation showed that, in average, 85.4% patients were correctly predicted to have a high or low risk of death at a given time point. Comparison with a traditional model using CA-125 half-life and time to reach CA-125 nadir showed that the longitudinal CA-125 model had an improved predicative value. CONCLUSION: Longitudinal CA-125 values, measured from the diagnosis of ovarian cancer to the completion of primary chemotherapy, could be used to reliably predict OS after adjusting for the stage and residual tumor disease. This model could be potentially useful in clinical counseling of patients with ovarian cancer.

A correlation exists between IOS pulmonary function and sICAM-1 and sVCAM-1.</p>

Inferior vena cava filter as a preventive device for recurrent pulmonary embolism in a patient with nephrotic syndrome

This study describes a patient with nephrotic syndrome who experienced recurrent pulmonary emboli as renal disease relapsed frequently. Clinical Presentation: A 30-year-old male, who was diagnosed as having nephrotic syndrome at 12, presented with general edema, ascites and hypoalbuminemia. Although the patient responded well to steroid therapy, a common cold frequently caused flare-up of nephrotic syndrome. Histopathological examination of renal tissue revealed minimal disease change. At 17, the patient had a first pulmonary embolism attack with concurrent upper respiratory tract infection. Fullblown manifestations of nephrotic syndrome with low antithrombin III levels were identified at that time. Anticoagulant therapy was administered to treat the pulmonary embolism. Since the first at-tack, several episodes of pulmonary emboli occurred, which, combined with kidney disease, triggered refractory nephrotic syndrome. The nephrotic syndrome did not remit, and a secondary renal biopsy identified glomerular patho-logical changes similar to previous biopsy results. To prevent recurrent pulmonary emboli, a Greenfield inferior vena cava filter was implanted in April 2002. No further pulmonary embolism events occurred after interventional filter deployment. The results of this study suggest that inferior vena cava filter implantation can be effective for preventing recurrent pulmonary embolism complicating refractory nephrotic syndrome
