RESUMEN

OBJECTIVE: Acute Physiology and Chronic Health Evaluation II (APACHE II) is based on the data of intensive care unit (ICU) patients and often correlates with disease severity and prognosis. However, no prognostic predictors exist based on ICU admission data for patients with brain tumors, and no studies have reported an association between APACHE II and prognosis in patients with brain tumors. The Japanese Intensive Care Patients Database (JIPAD) was established to improve the quality of care delivered in intensive care medicine in Japan. We used JIPAD to examine factors associated with in-hospital mortality based on available data of postoperative patients with brain tumors admitted to the ICU. METHODS: Patients aged ≥16 years enrolled in JIPAD between April 2015 and March 2018 after surgical brain tumor resection or biopsy of brain tumors. We examined factors related to outcomes at discharge based on blood tests and medical procedures performed during ICU admission, tumor type, and APACHE II score. RESULTS: Among the 1454 patients (male:female ratio: 1:1.1, mean age: 62 years) in the study, 32 (2.2 %) died during hospital stay. In multivariate analysis, male sex (odds ratio [OR] 2.70, [95 % confidence interval, CI 1.22-6.00]), malignant tumor (OR 2.51 [95 % CI 1.13-5.55]), and APACHE II score ≥15 (OR 2.51 [95 % CI 3.08-14.3]) were significantly associated with in-hospital mortality. CONCLUSION: By picking up cases with a high risk of in-hospital death at an early stage, it is possible to improve methods of treatment and support for the patient's family.

RESUMEN

Objectives: This study aimed to assess the clinical significance of Wideband Absorbance (WBA) in children with Large Vestibular Aqueduct Syndrome (LVAS), which could potentially serve as diagnostic and predictive markers for LVAS in children. Design: This was a single-center retrospective case-control study. Audiological measurements and Wideband Acoustic Immittance (WAI) were performed. Propensity score matching (PSM) was considered to treat group imbalance. The Receiver Operating Characteristic (ROC) curves and area under the ROC curve (AUC) were used to evaluate the sensitivity and specificity of WBA. Study sample: Participants included 42 children with LVAS and 163 normal children aged 6 months -11 years recruited from clinical audiology settings between 2019 and 2021. Results: The WBA at Tympanometric Peak Pressure (WBATPP) and Ambient Pressure (WBAA) in the LVAS group were significantly lower than those of the control group at 1259-2000 Hz but higher at 4000-6349 Hz (p < 0.05, power >0.8). The WBAA (1587 Hz) AUC value was 0.805, identifying a score ≤0.565 as indicative of a LVAS risk. Conclusions: WBA holds promise in distinguishing LVAS from the normal condition and warrants further exploration as a tool to examine the influence of inner ear pressure on acoustic energy transmission in the middle ear.

RESUMEN

PURPOSE: Acknowledging the associated risk factors may have a positive impact on reducing the incidence of ectopic pregnancy (EP). In recent years, body mass index (BMI) has been mentioned in research. However, few studies are available and controversial on the relationship between EP and BMI. METHODS: We retrospectively studied the EP women as a case group and the deliveries as a control group in the central hospital of Wuhan during 2017 ~ 2021. χ2 test of variables associated with ectopic pregnancy was performed to find differences. Univariate and multivariate binary logistic regression analysis was conducted to analyze the association of the variables of age, parity, history of induced abortion, history of ectopic pregnancy, history of spontaneous abortion, history of appendectomy surgery and BMI (< 18.5 kg/m2, 18.5 ~ 24.9 kg/m2, 25 kg/m2 ~ 29.9 kg/m2, ≥ 30 kg /m2) with EP. RESULTS: They were 659 EP and 1460 deliveries. The variables of age, parity, history of induced abortion, history of ectopic pregnancy and BMI were different significantly(P < 0.05). Multivariate analysis showed that the variables of age > 35 years old [(OR (Odds Ratio), 5.415; 95%CI (Confidence Interval), 4.006 ~ 7.320, P < 0.001], history of ectopic pregnancy (OR, 3.944; 95%CI, 2.405 ~ 6.467; P < 0.001), history of induced abortion(OR, 3.365; 95%CI, 2.724 ~ 4.158, P < 0.001) and low BMI (< 18.5 kg/m2) (OR, 1.929; 95%CI, 1.416 ~ 2.628, P < 0.001])increased the risk of EP. CONCLUSION: The history of ectopic pregnancy, history of induced abortion and age > 35 years old were the risk factors with EP. In addition to these traditional factors, we found low BMI (< 18.5 kg/m2) with women may increase the risk to EP.

RESUMEN

PURPOSE: This study aimed to investigate the relationship between spinal-pelvic parameters and recurrence of lumbar disc herniation (rLDH) after percutaneous endoscopic lumbar discectomy (PELD) through a retrospective case-control study. METHODS: Patients who underwent PELD for single-segment LDH at our hospital were included in this study. The relationship between sagittal balance parameters of the spine and recurrence was analysed through correlation analysis, and ROC curves were plotted. The baseline characteristics, sagittal balance parameters of the spine and radiological parameters of the case and control groups were compared, and the relationship between sagittal balance parameters of the spine and recurrence of rLDH after PELD was determined through univariate and multivariate logistic regression analysis. RESULTS: Correlation analysis showed that PI and ∆PI-LL were negatively correlated with grouping (r = -0.090 and -0.120, respectively, P = 0.001 and 0.038). ROC curve analysis showed that the area under the curve (ROC-AUC) for predicting rLDH based on PI was 0.65 (CI95% = 0.598, 0.720), with a cut-off of 50.26°. The ROC-AUC for predicting rLDH based on ∆PI-LL was 0.56 (CI95% = 0.503, 0.634), with a cut-off of 28.21°. Multivariate logistic regression analysis showed that smoking status (OR = 2.667, P = 0.008), PI ≤ 50.26 (OR = 2.161, P = 0.009), ∆PI-LL ≤ 28.21 (OR = 3.185, P = 0.001) and presence of Modic changes (OR = 4.218, P = 0.001) were independent risk factors, while high DH (OR = 0.788, P = 0.001) was a protective factor. CONCLUSION: PI < 50.26 and ∆PI-LL < 28.21 were risk factors for recurrence of lumbar disc herniation after spinal endoscopic surgery and had some predictive value for post-operative recurrence.

RESUMEN

BACKGROUND: Patient vital signs are a measure of wellness if monitored regularly and accurately. Staff shortages in poorly resourced regional hospitals often result in inadequate patient monitoring, putting patients at risk of undetected deterioration. OBJECTIVE: This study aims to explore the pattern and completeness of vital sign monitoring and the contribution of each vital sign in predicting clinical deterioration events in resource-poor regional/rural hospitals. METHOD: Using a retrospective case-control study design, we compared 24 h of vital sign data from deteriorating and nondeteriorating patients from two poorly-resourced regional hospitals. Descriptive statistics, t-tests, and analysis of variance are used to compare patient-monitoring frequency and completeness. The contribution of each vital sign in predicting patient deterioration was determined using the Area Under the Receiver Operator Characteristic curve and binary logistical regression analysis. RESULTS: Deteriorating patients were monitored more frequently (9.58 [7.02] times) in the 24-h period than nondeteriorating patients (4.93 [2.66] times). However, the completeness of vital sign documentation was higher in nondeteriorating (85.2%) than in deteriorating patients (57.7%). Body temperature was the most frequently omitted vital sign. Patient deterioration was positively linked to the frequency of abnormal vital signs and the number of abnormal vital signs per set (Area Under the Receiver Operator Characteristic curve: 0.872 and 0.867, respectively). No single vital sign strongly predicts patient outcomes. However, a supplementary oxygen value of >3 L/min and a heart rate of >139 beats/min were the best predictors of patient deterioration. CONCLUSION: Given the poor resourcing and often geographical remoteness of small regional hospitals, it is prudent that the nursing staff are made aware of the vital signs that best indicate deterioration for the cohort of patients in their care. Tachycardic patients on supplementary oxygen are at high risk of deterioration.

RESUMEN

The tree-based scan statistic is a data mining method used to identify signals of adverse drug reactions in a database of spontaneous reporting systems. It is particularly beneficial when dealing with hierarchical data structures. One may use a retrospective case-control study design from spontaneous reporting systems (SRS) to investigate whether a specific adverse event of interest is associated with certain drugs. However, the existing Bernoulli model of the tree-based scan statistic may not be suitable as it fails to adequately account for dependencies within matched pairs. In this article, we propose signal detection statistics for matched case-control data based on McNemar's test, Wald test for conditional logistic regression, and the likelihood ratio test for a multinomial distribution. Through simulation studies, we demonstrate that our proposed methods outperform the existing approach in terms of the type I error rate, power, sensitivity, and false detection rate. To illustrate our proposed approach, we applied the three methods and the existing method to detect drug signals for dizziness-related adverse events related to antihypertensive drugs using the database of the Korea Adverse Event Reporting System.

RESUMEN

INTRODUCTION: Abiraterone and concurrent androgen deprivation therapy (ADT) are used in the treatment of patients with metastatic castration-resistant prostate cancer. Recently, it has been suggested that the use of abiraterone alone (without ADT) may have comparable efficacy to abiraterone with ongoing ADT. Here, we sought to assess the impact of ADT cessation in patients beginning abiraterone for castration-resistant prostate cancer. METHODS: We identified 39 patients at our institution who received abiraterone alone (with discontinuation of ADT) between 2011 and 2022. We then procured a comparable group of 39 patients (matched by age, Gleason score, and prostate-specific antigen [PSA] level) who received abiraterone with ongoing ADT during the same period. We assessed and compared clinical outcomes in the two groups (abiraterone-alone vs. abiraterone-ADT) with respect to PSA response rates, PSA progression-free survival, and overall survival. Results were adjusted using Cox proportional-hazards multivariable models. RESULTS: The median PSA before treatment initiation was 12.7 (range: 0.2-199) ng/mL in the abiraterone-alone group and 15.5 (range: 0.6-212) ng/mL in the abiraterone-ADT group. Use of abiraterone alone adequately suppressed testosterone levels in 35/37 (94.6%) patients. Patients receiving abiraterone alone had a median PSA reduction of 80.2% versus 79.5% in patients receiving abiraterone plus ADT. The median PSA progression-free survival in patients receiving abiraterone alone was 27.4 versus 25.8 months in patients receiving abiraterone plus ADT (hazard ratio [HR] 1.10; 95% confidence interval [CI] 0.65-1.71; p = 0.82). In addition, abiraterone alone was associated with an overall survival of 3.6 versus 3.1 years in patients receiving abiraterone plus ADT (HR 0.90; 95% CI 0.50-1.62; p = 0.72). There were no differences in PFS or OS between groups after performing Cox multivariable regression analyses. CONCLUSION: Use of abiraterone alone was associated with comparable clinical outcomes to patients who received abiraterone together with ADT. Further prospective studies are warranted to evaluate the impact of abiraterone alone on treatment outcomes and cost savings.

RESUMEN

OBJECTIVE: To explore the characteristics and risk factors of facial pressure injuries in patients using noninvasive positive pressure ventilation. SETTING AND SAMPLE: Patients who developed facial pressure injuries due to non-invasive positive pressure ventilation at a teaching hospital in Taiwan from January 2016 to December 2021 were selected, resulting in a total of 108 patients in our case group. A control group was formed by matching each case by age and gender to three acute inpatients who had used non-invasive ventilation but had not developed facial pressure injuries, resulting in 324 patients in the control group. RESEARCH METHODOLOGY: This study was a retrospective case-control study. The characteristics of the patients who developed pressure injuries at different stages in the case group were compared, and the risk factors of non-invasive ventilation-related facial pressure injuries were then determined. RESULTS: Higher duration of non-invasive ventilation usage, higher length of hospital stay, lower Braden scale score, and lower albumin levels in the former group. The results of multivariate analysis from binary logistic regression involving the duration of non-invasive ventilation usage demonstrated that the patients who used this device for 4-9 days and 16 days were at greater risk of facial pressure injuries than those who used it for 3 days; in terms of the Braden scale score, higher Braden scale scores were correlated with a higher risk of facial pressure injuries. In addition, albumin levels lower than the normal range were correlated with a higher risk of facial pressure injuries. CONCLUSION: Patients with pressure injuries at higher stages had a higher duration of non-invasive ventilation usage, higher length of hospital stay, lower Braden scale scores, and lower albumin levels. Thus, a longer duration of non-invasive ventilation use, lower Braden scale scores, and lower albumin levels were also risk factors for non-invasive ventilation-related facial pressure injuries. IMPLICATIONS FOR CLINICAL PRACTICE: Our results serve as a useful reference for hospitals, both in creating training programs for their medical teams to prevent and treat facial pressure injuries and in drafting guidelines for assessing risk in order to prevent facial pressure injuries caused by non-invasive ventilation. The duration of device usage, Braden scale scores, and albumin levels in particular should be seriously monitored to reduce the occurrence of facial pressure injuries in acute inpatients treated with non-invasive ventilation.

RESUMEN

Colorectal cancer (CRC) is a major public health issue, and there are limited studies on the association between 17ß-hydroxysteroid dehydrogenase type 4 (HSD17B4) polymorphism and CRC. We used two national databases from Taiwan to examine whether HSD17B4 rs721673, rs721675, and alcohol intake were independently and interactively correlated with CRC development. We linked the Taiwan Biobank (TWB) participants' health and lifestyle information and genotypic data from 2012 to 2018 to the National Health Insurance Database (NHIRD) to confirm their medical records. We performed a genome-wide association study (GWAS) using data from 145 new incident CRC cases and matched 1316 healthy, non-CRC individuals. We calculated the odds ratios (OR) and 95% confidence intervals (CI) for CRC based on multiple logistic regression analyses. HSD17B4 rs721673 and rs721675 on chromosome 5 were significantly and positively correlated with CRC (rs721673 A > G, aOR = 2.62, p = 2.90 × 10-8; rs721675 A > T, aOR = 2.61, p = 1.01 × 10-6). Within the high-risk genotypes, significantly higher ORs were observed among the alcohol intake group. Our results demonstrated that the rs721673 and rs721675 risk genotypes of HSD17B4 might increase the risk of CRC development in Taiwanese adults, especially those with alcohol consumption habits.

RESUMEN

Background: An increased risk of gallstones has been observed in patients undergoing hepatectomy. This study attempted to analyze the risk factors for gallstones after hepatectomy. Methods: From January 2013 to December 2016, clinical data of 1,452 eligible patients who underwent hepatectomy were consecutively reviewed. According to the imaging, including gallbladder ultrasound, computerized tomography, and magnetic resonance imaging, all patients were divided into the gallstone group and the nongallstone group. Univariate and multivariate logistic regression analyses were performed to select indicators associated with gallstone formation among patients after hepatectomy. Results: In the total sample of included patients, there were 341 patients with gallstones and 1,147 patients without gallstones. The incidence of gallstones was 23.5% (341/1,452). The incidence of gallstones in the primary liver cancer group was higher than that in the benign liver tumor group (25.7% vs. 18.9%, P = 0.004). Univariate and multivariate logistic regression analyses showed that female gender, high body mass index, tumor located in S5, and severe postoperative complication were factors related to gallstones in patients with benign liver tumors after hepatectomy. In addition, Child-Pugh B, low albumin, liver cirrhosis, and transcatheter arterial chemoembolization (TACE) after recurrence were factors related to gallstones in patients with primary liver cancer after hepatectomy. Conclusions: Hepatectomy increased the risk of gallstones in benign or malignant liver tumors, especially when the tumor was located in S5. TACE further increased the risk of gallstones in patients with postoperative recurrence.

RESUMEN

Objective: To investigate the early predictive factors for Kawasaki disease complicated with macrophage activation syndrome (KD-MAS). Methods: We performed a retrospective case-control study in children with KD from August 2017 to August 2022, involving 28 cases with KD-MAS and 112 cases not developing KD-MAS. Based on the univariate analysis, binary logistic regression was used to identify the early predictive factors for KD-MAS development, and the receiver operating characteristic curve (ROC) analysis was carried out to obtain the optimal cut-off value. Results: Two predictive factors were associated with the development of KD-MAS, which were PLT (OR = 1.013, 95%CI, 1.001-1.026), and serum ferritin (OR = 0.991, 95%CI, 0.982-0.999). The cut-off value of PLT was 110 × 109/L, and the cut-off value of serum ferritin was 548.4 ng/ml. Conclusion: Children with KD who had a PLT count under 110 × 109/L, and a serum ferritin level over 548.4 ng/ml are more likely to develop KD-MAS.

RESUMEN

Background: During the perioperative period, empiric antibiotic escalation therapy is not uncommon, leading to longer postoperative hospital stay and higher medical expenses. However, few systematic studies have investigated this issue. In this case-control study, we explored the factors affecting empiric antibiotic escalation therapy after minimally invasive lung surgery during hospitalization, with the aim to enhance recovery after surgery and rational use of antibiotics. Methods: The data of patients who underwent minimally invasive lung surgery at our center from January 2019 to December 2020 were collected from the hospital information system (HIS). A total of 1,360 cases were identified based on the inclusion and exclusion criteria. These patients were divided into 2 groups: group A (n=825), in which patients did not receive antibiotic escalation therapy after surgery; and group B (n=535), in which patients received empiric antibiotic escalation therapy after surgery. A logistic regression model was used to analyze the influencing factors of empiric antibiotherapy escalation during postoperative hospitalization. Results: Compared with group A, group B had significantly longer postoperative hospital stay (5.05±2.78 vs. 4.49±2.24 days, P<0.001) and slightly higher average total hospitalization costs (74,080.85±23,796.51 vs. 71,798.09±21,307.26 yuan, P=0.067). Multivariate analysis showed that the statistically significant factors included history of secondary lung surgery [odds ratio (OR): 3.267; 95% confidence interval (CI): 1.305-8.178; P=0.011], preoperative hemoglobin A1c (HbA1c) ≥6.5% (OR: 1.603; 95% CI: 1.143-2.249; P=0.006), postoperative fever of unknown origin [temperature (T) >38 ℃; OR: 2.494; 95% CI: 1.321-4.708; P=0.005], postoperative hypoalbuminemia (intravenous albumin administration for ≥2 days; OR: 14.125; 95% CI: 1.777-112.282; P=0.012). Conclusions: Multivariate analysis showed that history of secondary lung surgery, preoperative HbA1c ≥6.5%, postoperative fever of unknown origin (T >38 ℃), and postoperative hypoalbuminemia (<35 g/L and intravenous albumin administration ≥2 days) were the independent risk factors for empiric antibiotic escalation therapy after minimally invasive lung surgery. For preoperative risk factors, further cohort studies should be conducted to explore better intervention indicators or measures. For postoperative risk factors, perioperative dynamic monitoring of procalcitonin can guide the rational use of antibiotics, reduce the risk of drug resistance and hospitalization cost.

RESUMEN

AIMS AND OBJECTIVES: This study aimed to investigate factors associated with facial pressure injury (FPI) in patients receiving non-invasive positive pressure ventilation (NIPPV) during hospitalisation in the intensive care unit (ICU) and to identify predictors of FPI. BACKGROUND: Non-invasive positive pressure ventilation is a method of treating patients with acute and chronic respiratory failure. However, FPI may occur due to unsuitable nasal-oral NIPPV masks and discomfort in contact with the skin surface. DESIGN: A retrospective case-control study. METHODS: From January 2018 to October 2020, a total of 397 patients admitted to a national hospital in Taiwan were enrolled. Patients received NIPPV and routinely used under-mask prophylactic dressings during hospitalisation. Patients were divided into the non-FPI group (n = 357) and the FPI group (n = 40). Demographic, clinical characteristics, acute physiology and chronic health evaluation II scores, and Braden Scale scores were collected from medical records. Logistic regression analysis was performed to examine the contribution of each factor to the FPI, and odds ratios were reported. The STROBE checklist was used in this retrospective case-control study. RESULTS: There were significant differences between the groups in age, serum albumin, C-reactive protein, body mass index (BMI), disease severity, Braden Scale score, length of stay, duration of mechanical ventilation and use of corticosteroids. Logistic regression analysis revealed that the risk factor for FPI was the Braden Scale score [OR = 1.630 (1.176-2.260)], BMI [OR = 0.396 (0.210-1.784)] and corticosteroids [OR = 0.394 (0.159-1.811)], which were predictors of FPI in patients with NIPPV. CONCLUSIONS: Facial pressure injury may still occur in patients who routinely use prophylactic dressings under NIPPV masks. This study provides information on continuing education training for FPI to more accurately identify high-risk and timely preventive measures to reduce FPI. RELEVANCE TO CLINICAL PRACTICE: Addressing FPI-related factors to prevent facial skin damage and reduce comorbidities in patients using NIPPV masks.

RESUMEN

OBJECTIVE: We conducted a retrospective case control study to examine whether remote monitoring of Cheyne-Stokes breathing (CSB) was useful for predicting the onset of heart failure (HF) in patients with obstructive sleep apnea (OSA) on continuous positive airway pressure (CPAP). METHODS: Among patients with OSA treated at our hospital, 33 patients with HF that occurred between July 2014 and May 2021 [11 patients with acute HF (AHF); 22 patients with chronic HF (CHF) exacerbation] were included in the HF group. Of the 618 stable patients, 149 patients with a 30-days average CSB rate (CSB%) ≧1% were included in the non-HF control group. The chronologic change of CSB% were compared among the AHF, CHF and Control groups. Furthermore, of the 149 patients in the non-HF control group, 44 patients were matched for CSB%, body mass index, and sex in a ratio of 1:2 to 22 patients with CHF. The average cycle length (CL) of CSB was compared among three groups: CHF in stable period (CHF-stable group), CHF in exacerbation period (CHF-exacerbation group), and control group. In addition, according to the status of HF, receiver operating characteristic (ROC) curves were generated to determine the optimal cut-off points for variation of CSB% and CL. RESULTS: Chronological change in CSB% among the three groups was significantly different. Standard deviation of CSB% (SD CSB%) before onset HF was significantly higher in both the AHF and CHF groups than in the control group. The CL of CSB was significantly longer in the CHF group than in the control group and was longer during the exacerbation period than during the stable period. The optimal cut-off value of CL that could differentiate patients with and without the onset of HF was 68.9 s. CONCLUSION: The HF group demonstrated greater CSB variations and longer CL than the non-HF control group. Furthermore, the CL was longer during the exacerbation period of HF even in the same patient. These results suggest that remote monitoring of CPAP device data for CSB variations and CL might allow early prediction of the onset and exacerbation of HF.

RESUMEN

Background and Objective: Coronavirus disease 2019 (COVID-19) is a viral infectious disease caused by the severe acute respiratory syndrome virus, which has affected billions of people across the globe. The pathogenesis of respiratory inflammation involves elevated concentration of interleukin-6; hence, interventions targeting interleukin-6 receptor, such as tocilizumab (TCZ), have been investigated as potential treatment amidst the dilemma of COVID-19 management. The aim of the study is to analyse the efficacy and safety of TCZ and record the outcome in COVID-19 patients. Materials and Methods: A retrospective case-control study of 80 patients in each group (N = 160) was carried out in a tertiary care hospital in Vadodara, Gujarat. Non-pregnant COVID-19-positive patients above 12 years of age were included in the study and were divided into case (those given TCZ) and control (those given standard treatment) groups after collecting their history and related data. From each group, further data was collected in the form of general and systemic examination, investigations and calculation of inflammatory and Sequential Organ Failure Assessment (SOFA) scores. Results: Overall mortality was less in the case group compared to the control group. Patients with moderate to severe disease, age <55 years, patients having no comorbidity and patients with higher oxygen demand had lower deaths when given TCZ. Inflammatory score <3 and SOFA score <6 were associated with reduced mortality in the case group. Additionally, the study found significant results by simultaneously analysing two parameters in combination, which has not been done in any other study to the best of our knowledge. Conclusions: Adjuvant TCZ therapy had overall mortality benefit compared to standard treatment, with specific benefit observed in those with increasing disease severity, young to middle-age group, absence of comorbidity, higher oxygen requirements and lower inflammatory and SOFA scores.

RESUMEN

To establish a risk prediction model and the clinical value of trisomy 21 using alpha-fetoprotein variants L2 (AFP-L2) combined with maternal serum biomarkers and nuchal translucency (NT) thickness in early pregnancy. A retrospective case-control study was conducted. The subjects were divided into the case group (n = 40) or the control group (n = 40). An enzyme-linked immunosorbent assay was used to measure the maternal serum AFP-L2 level in both groups. The AFP-L2 single-index or multi-index combined risk model was used to predict the efficiency of trisomy 21. The best cut-off value and area under the curve (AUC) were determined to evaluate the predictive efficacy of different risk models constructed by AFP-L2. The maternal serum AFP-L2 level in the case group was 1.59 (0.61-3.61) Multiple of medium (MoM), which was higher than 1.00 (0.39-2.12) MoM in the control group (P < 0.001). The free beta-human chorionic gonadotropin (free ß-hCG) level and NT in the case group were significantly higher than those in the control group (P < 0.001). The pregnancy-associated plasma protein A (PAPP-A) level in the case group was lower than that in the control group (P < 0.001). The AUC of AFP-L2 in predicting trisomy 21 was 0.797. After considering the maternal serum AFP-L2 level, the AUC, detection rate (DR), positive predictive value (PPV), negative predictive value (NPV), falsepositive rate (FPR), false negative rate (FNR), positive likelihood ratio (+LR), and negative likelihood ratio (-LR) were significantly improved. In this study, PAPP-A + free ß-hCG + NT + AFP-L2 and PAPP-A + free ß-hCG + AFP-L2 increased the integrated discrimination improvement (IDI) and net classification improvement (NRI) of predicting fetuses with trisomy 21 (1.10% and 5.27%; 11.07% and 2.78%)  (1.10% and 5.27%; 11.07% and 2.78%), respectively, after considering the maternal serum AFP-L2 level. The maternal serum AFP-L2 level in early pregnancy had high sensitivity and specificity, and it was a good biomarker to predict fetuses with trisomy 21.

RESUMEN

BACKGROUND: The coexistence of primary hyperparathyroidism and papillary thyroid carcinoma (PTC) is common and may be associative with more aggressive PTC, with higher rates of extrathyroidal extension and multicentricity. However, it is unclear whether secondary hyperparathyroidism (SHPT) is associated with more invasive PTC in terms of morbidity, tumor pathological characteristics, and prognosis. The aim of this study was to evaluate the rate and tumor characteristics of PTC in patients with SHPT. METHODS: A total of 531 patients diagnosed with SHPT who underwent surgery from August 2013 to December 2018 at the First Affiliated Hospital of Zhejiang University were evaluated retrospectively. Patient demographics, surgical records, and follow-up information were recorded and analyzed. Control subjects were matched to the enrolled patients in a 1:4 ratio in terms of age, sex and pathological subtype. RESULTS: Among the 531 patients with SHPT who underwent surgery, 34 had coexisting PTC and PTC + SHPT (6.4%). The mean tumor diameter in the PTC + SHPT group was smaller than that in the PTC group (5.57 mm vs 9.00 mm, p < 0.001). The proportion of papillary thyroid micro-carcinoma in the PTC + SHPT group was significantly higher than that in the PTC group (29 [85.29%] vs. 86[63.24%], p = 0.014). There were no statistically significant differences between groups in terms of tumor multicentricity (15 [44.12%] vs 39 [28.68%], p = 0.066), tumor bilaterality (9 [26.47%] vs. 29 [21.32%], p = 0.499), tumor extrathyroidal extension (2 [5.88%] vs. 19 [13.97%], p = 0.255), or lymph node (LN) metastasis rate (12 [35.29%] vs. 49 [36.03%], p = 1.000). However, the PTC + SHPT and PTC groups were significantly different in terms of contralateral thyroidectomy (10 [29.41%] vs. 70 [51.47%], p = 0.023) and lymph node dissection (22 [64.71%] vs. 125 [91.91%], p < 0.001).There was no significant difference between the PTC + SHPT and PTC groups in terms of prognostic staging (33 [97.06%] vs. 122 [89.71%], p = 0.309) or recurrence (mean follow-up time: 36 months vs. 39 months, p = 0.33). CONCLUSIONS: The prevalence of PTC is high in patients with SHPT; compared with PTC in the general population, most papillary thyroid carcinomas with SHPT are occult thyroid carcinomas and present no significant difference in terms of tumor pathological features and prognostic staging. It is necessary for surgeons to perform more adequate preoperative examination and be more careful during surgery to avoid missing the coexistence of PTC in patients with SHPT.

RESUMEN

PURPOSE: Previous evidence has shown that psychological stress can trigger the onset of autoimmune disease. This study aimed to investigate the prevalence of stressful life events preceding the onset of symptoms in female primary Sjogren's syndrome (pSS) in China compared to controls and the possible associations of stressful life events with disease activity. PATIENTS AND METHODS: This was a hospital-based retrospective case-control study. Sixty-seven consecutive female pSS patients and an equal number of age-matched (± 3 years) healthy controls were recruited for assessment using the related Stressful Life Events Scale. The pSS disease activity was measured by the EULAR Sjogren's syndrome disease activity index. Data were analyzed by SPSS, version 23, using chi-square, univariate logistic regression, multiple logistic regression, and partial correlation. RESULTS: A higher number of negative stressful life events before disease onset in pSS patients compared with healthy controls suggest that these play a role in increasing the risk of disease occurrence (OR = 2.59, 95% CI: 1.87-3.58, p < 0.05). The number of positive life events did not differ between the two groups. Both the number and severity of the negative stressful life events were also significantly correlated with disease activity. CONCLUSION: Patients with pSS experienced more negative stressful life events in the year preceding the onset of symptoms than controls. Negative stressful life events before symptom onset may be risk factors for pSS and may affect pSS disease activity.

RESUMEN

PURPOSE: This study sought to identify the complication, mortality, and readmission rates of patients undergoing either percutaneous (PCLB) or transjugular liver biopsy (TJLB) when propensity matched for demographics and hepatic comorbidities. METHODS: A retrospective review of New York's Statewide Planning and Research Cooperative System ICD9 coded database from the years 2009-2013 was conducted. Patients over the age of 18 undergoing either PCLB or TJLB were included. Patients with hepatic neoplasm or metastasis were excluded. 2:1 PCLB:TJLB propensity match for age, race, payment, coagulopathy, thrombocytopenia/purpura, hypercoagulability, ascites, acute liver failure, chronic hepatitis, cirrhosis, and bone marrow disease was conducted. Univariate analysis compared demographics, complications, readmissions, and mortality. RESULTS: 1467 patients met inclusion criteria (PCLB = 978, TJLB = 489). Propensity match was successful in that there were no significant differences in demographics or hepatic comorbidities. TJLB had significantly lower rates of hematoma (0.20 % vs 1.20 %, p = 0.049) and higher rates of cardiac complications (0.40 % vs 0.00 %, p = 0.045). Other complication, readmission, and mortality rates did not differ significantly. Logistic regression found no significant predictors of readmission within 7 days or any complication within 5 days. CONCLUSION: This retrospective, multi-center database review of adult patients undergoing PCLB or TJLB propensity matched for demographics and hepatic comorbidities found that TJLB patients had a significantly higher rate of cardiac complications while PCLB patients had a significantly higher rate of hematoma. These findings support prior literature suggesting a trend towards safety of TJLB compared to PCLB in patients with hemostatic disorders and/or advanced liver disease.

RESUMEN

BACKGROUND: Technical factors leading to hernia recurrence after transabdominal preperitoneal repair include insufficient dissection, inadequate prosthetic overlap and prosthetic size, improper fixation and folding, or crinkling of the prosthesis. However, determining intraoperatively if a case will develop recurrent hernias due to these factors remains unclear. METHODS: Five surgeons blind-reviewed operation videos of primary laparoscopic hernioplasty in 13 lesions that went on to develop recurrent hernias (i.e., future recurrence), as well as 28 control lesions, to assess twelve items of surgical techniques. Since we changed a surgical policy of covering myopectineal orifice (MPO) in April 2003, we analyzed the data for the earlier and later periods. The data was analyzed with hierarchical clustering to obtain a gross grouping. The differences of the ratings between the future recurrent and control lesions were then analyzed and the association of the techniques with the hernia recurrence rate, the size of the prosthesis, and the hernia type across hernia recurrence were explored. RESULTS: The lesions were grouped based on the time series, and its boundary was approximated when we changed our surgical policy. This policy change caused ratings to progress from 34% satisfactory, to 79% satisfactory. The recurrence rate decreased to 0.7% (5/678), compared with 6.2% (10/161) before the policy was implemented (p < 0.001). With univariate analysis, the ratings of posterior prosthesis overlap to the MPO in the recurrent lesions were significantly lower than controls in the later period (p = 0.019). Although various types of recurrences were noted in the earlier period, only primary indirect and recurrent indirect hernias were observed in the later period (p = 0.006). CONCLUSIONS: Fully covering the MPO with mesh is essential for preventing direct recurrence hernias. Additional hernia recurrence prevention can be obtained by giving appropriate attention to prosthesis overlap posterior to the MPO in a large indirect hernia.
