Preoperative comprehensive malignancy risk estimation for thyroid nodules: Development and verification of a network-based prediction model

BackgroundIn order to avoid excessive treatment of thyroid nodules in the clinic, it is necessary to find a simple and practical analysis method to comprehensively and accurately reflect benign or malignant thyroid nodules. This study aimed to construct and validate a comprehensive and reliable network-based predictive model using a variety of imaging and laboratory criteria for thyroid nodules to stratify the risk of malignancy prior to surgery.MethodsWe retrospectively analyzed data from patients who underwent surgical treatment for thyroid nodules at the Thyroid and Breast Diagnosis and Treatment Center of Weifang Hospital of Traditional Chinese Medicine between January 2018 and December 2020. Binary logical regression analysis was performed to predict whether nodules were malignant or benign. The developmental dataset included 457 patients (January 2018–December 2020). The validation set included separate data points (n = 225, January 2018–December 2020).ResultsIn this study, criteria that showed significant predictive value for malignant nodules included TI-RADS: 4b (p = 0.065); Bethesda IV, Bethesda V, Bethesda VI (P < 0.0001); BRAF^V600E mutation (P < 0.0001); Calcitonin>5 pg/ml (p = 0.0037); and FNA-Tg>30 ng/ml (p = 0.0003). A 10-grade risk scoring system was developed. The risk of malignancy risk ranged from 2.06% to 100% and was positively associated with increasing risk grade. The areas under the receiver-operating characteristic curve of the development and validation sets were 0.972 and 0.946, respectively.ConclusionA simple, comprehensive and reliable web-based predictive model was designed using a variety of imaging and laboratory criteria to stratify thyroid nodules by probability of malignancy.     

Filiform needle acupuncture for allergic rhinitis: A systematic review and meta-analysis

BackgroundFiliform needle acupuncture (FNA), the most classical and widely applied acupuncture method based on traditional Chinese medicine theory, has shown a promising effect in the treatment of allergic rhinitis (AR).ObjectiveTo evaluate the efficacy, safety, cost-effectiveness, and patient preference of FNA in the treatment of AR by comparing FNA with sham acupuncture, no treatment, and conventional medication.Search strategyEight electronic databases were systematically searched from inception to October 14, 2021. Additional studies were acquired from clinical trial registration platforms and reference lists.Inclusion criteriaRandomized controlled trials were included if they compared FNA with either sham acupuncture, no treatment or conventional medication for AR.Data extraction and analysisTwo researchers extracted data independently of each other using a predesigned data acquisition form, and results were cross-checked after completion. The primary outcome was symptom score (Total Nasal Symptom Score or Visual Analogue Scale), and the secondary outcomes were the AR control questionnaire, quality of life (QoL) score (Different versions of Rhinoconjunctivitis Quality of Life Questionnaire), medication score (use of rescue medication), mental health score, total IgE, adverse event rate, clinical economic indicators, and patient satisfaction score. Standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval was used to calculate the effect size for continuous data, while risk ratio with 95% CI was used for dichotomous data.ResultsThirty studies were included in this review. Compared with sham acupuncture, FNA significantly reduced the symptom score (SMD: ?0.29 [?0.43, ?0.15]), AR’s impact on QoL (SMD: ?0.23 [?0.37, ?0.08]) and medication score (SMD: ?0.3 [?0.49, ?0.11]). Compared with no treatment, FNA dramatically reduced the symptom score (SMD: ?0.8 [?1.2, ?0.39]) and AR’s impact on QoL (SMD: ?0.82 [?1.13, ?0.52]). There were no increased rates of adverse events with FNA compared to sham acupuncture and no treatment. FNA increased patient satisfaction and may be cost-effective. Most pieces of evidence from the above two comparisons were of high confidence. Moreover, FNA significantly outperformed conventional medication in reducing the symptom score (SMD: ?0.48 [?0.85, ?0.1]) and displayed a lower rate of adverse events, but the quality of evidence was very low.ConclusionFNA is an effective and safe intervention for AR and can help with symptom relief, QoL improvement, reducing medication usage, and increasing patient satisfaction. Further studies are needed to verify its cost-effectiveness and superiority over conventional medication and the best therapeutic strategies.

Patient and Procedure-related Characteristics Correlated With Severity of Hemoptysis Following Percutaneous Transthoracic Needle Biopsy: Results of a 10-year Retrospective Review

PurposeA risk of percutaneous transthoracic needle biopsy (PTNB) is hemoptysis, which can range from mild to life-threatening. The reported occurrence of hemoptysis is 1.7% to 14.5%, and the demographic, patient, and procedure characteristics have not been extensively described. The purpose of this study was to assess the associations of demographic, patient, and procedure characteristics with the severity of hemoptysis.Materials and MethodsA single institution, single group, retrospective, electronic medical record (EMR) review was performed on all hemoptysis events occurring between 2008 and 2018. Demographic, clinical, and procedure variables were extracted from EMRs. Outcome of hemoptysis events was graded using Common Terminology Criteria for Adverse Events (CTCAE). Mild-moderate and severe hemoptysis were defined as CTCAE classifications of 1-2 and 3-5, respectively. Associations were generated using logistic regressions and Likelihood Ratio Chi-Square tests.ResultsIn 10 years, 14,665 PTNB resulted in 231 hemoptysis events occurring in 229 patients; 12.7% (n = 29) of those were severe. The strongest and statistically significant variables associated with an increased likelihood of a severe event, if an event occurred, were cigarette pack years (OR = 1.02, 95% C.I. = 1.01-1.04, p = .020); history of chronic obstructive pulmonary disease (COPD) (OR = 3.68, 95% C.I. = 1.53-8.82, p = .003); core biopsy technique (OR = 8.13, 95% CI = 1.07, 61.40, p = .042), and larger diameter needle (20 g vs. 18 g: OR = 2.60, 95% CI 1.09, 6.17, p = .031).ConclusionsPTNB-associated hemoptysis was an uncommon event that was rarely life-threatening. The extent of the patient’s smoking history, the diagnosis of COPD, and core biopsy technique were associated with an increased likelihood of severe hemoptysis.     

Accurate detection of reemergent anti-donor ABO antibody is crucial for safe transfusion in ABO major incompatible HSCT patient after achieved the stages of full switch to donor type

Dynamic monitoring ABO chimera including erythroid ABO antigen and anti-A/B is crucial to not only assess the status of erythroid engraftment but also achieve personalized safety transfusion in patients post ABO incompatible hematopoietic stem cell transplantation. Transfusion support for ABO incompatible (ABOi) HSCT patients after achieved complete alteration to donor origin still remains cautious because the instant hematopoietic status on these transplant patients possibly returned to patient origin derived from early disease relapse and graft loss or failure. We reported that reemergent anti-B in a female patients (donor/patient: B/O) at the early phase after achievement complete donor type were not effectively found from partial automatic ABO blood grouping systems, which directly resulted in differential judgement of transplantation stage for about 15 days and disturbed the optimal recommendation on transfusion support. Meanwhile, the solely alteration of ABO chimera was found and earlier than changes of other markers such as MRD diagnosis, chimerism analysis by STR-PCR and sex chromosome assays, which can be an available predictors for bad transplant outcomes such as graft failure.     

An economic analysis of the cost of survival of micro preemies: A systematic review

ObjectiveThis study aimed to systematically review the current literature on the economic costs of micro preemie as well as evidence on the cost-effectiveness of interventions to improve outcomes for micro preemie babies with a birth weight of ≤500 g.MethodWe searched MEDLINE, CINAHL, Scopus, ECONLIT, Business Source Premier and Cochrane Library for studies reporting costs of micro preemie from January 2000. Costs were inflated to 2019 United States dollars (US$). All full-text articles were assessed for eligibility and a quality assessment of included articles was conducted using the Drummond and the Larg and Moss checklists.ResultsThe search identified three studies that met the inclusion criteria; two cost-of-illness studies and one cost-effectiveness study. Across studies, the mean healthcare spending per micro preemie survivor (in 2019 US$) ranged from US$61,310 (birth admission) to US$263,958 (inpatient and outpatient for the first six months of life). One modelling study reported exclusive human milk diet for micro preemies at birth was more cost-effective compared to the standard approach with cow milk diet from the third-party payer and societal perspectives.ConclusionDespite significant advances in perinatal care and expanded access to life-saving equipment to improve survival outcomes of micro preemie, there remains a paucity of research on economic costs associated with these babies. No study has utilised quality-adjusted life-years as an outcome measure. Given the chronic conditions and long-term neurologic disability associated with micro preemie survivors, an estimate of the lifetime cost to the individual, healthcare providers and society would provide a benchmark of the potential cost-savings that could accrue from cost-effective interventions to improve the survival rate of micro preemies.
