Mortality in patients admitted to hospital with heart failure in China: a nationwide Cardiovascular Association Database-Heart Failure Centre Registry cohort study

China has the largest burden of heart failure worldwide. However, large-scale studies on heart failure mortality are scarce. We aimed to investigate mortality and identify risk factors for mortality among patients with heart failure in China. This prospective cohort study used data from the China Cardiovascular Association (CCA) Database-Heart Failure Centre Registry, which were linked to the National Mortality Registration Information Management System by the Chinese Centre for Disease Control and Prevention. We included patients enrolled from Jan 1, 2017, to Dec 31, 2021, across 572 CCA Database-Heart Failure Centre certified hospitals in 31 provinces of mainland China. Eligible patients were aged 18 years or older (younger than 100 years) with a principal discharge diagnosis of heart failure based on Chinese heart failure guidelines. All-cause mortality at 30 days, 1 year, and 3 years for patients with heart failure were calculated and the causes of death were recorded. Multivariable analysis was used to analyse factors associated with all-cause mortality and cardiovascular mortality. This study was registered with the Chinese Clinical Trial Registry, ChiCTR2200066305. Of the 327 477 patients in the registry, 230 637 eligible adults with heart failure were included in our analyses. Participant mean age was 69·3 years (SD 13·2), 94 693 (41·1%) participants were female, and 135 944 (58·9%) were male. The median follow-up time was 531 days (IQR 251-883). Post-discharge all-cause mortality of patients with heart failure at 30 days was 2·4% (95% CI 2·3-2·5), at 1 year was 13·7% (13·5-13·9), and at 3 years was 28·2% (27·7-28·6). Cardiovascular death accounted for 32 906 (71·5%) of 46 006 all-cause deaths. Patients with heart failure with reduced ejection fraction had the highest all-cause mortality. A lower guideline adherence score was independently associated with the increase of all-cause and cardiovascular mortality. In China, mortality for patients with heart failure is still high, especially in patients with reduced ejection fraction. Our findings suggest that guideline-directed medical therapy needs to be improved.

Fatigue, depression, and sleep disorders are more prevalent in patients with metabolic-associated fatty liver diseases.

To determine the prevalence and risk factors for depression, sleep disturbances, and exhaustion in MAFLD patients. Two hundred twenty-four consecutive patients with MAFLD attending the outpatient clinic from April to October 2023; were subjected to clinical evaluation, laboratory testing including non-invasive laboratory markers, fibroscan (measuring steatosis and fibrosis), and different quantitative and qualitative fatigue scores. A control group including 342 patients without MAFLD was taken. The prevalence of fatigue, depression, and sleeping disorders in the MAFLD group was 67.8%, 75%, 62.5% vs 21%, 16.4%, and 19.5% in the control group respectively ( P = <0.001, P = <0.001 and P = <0.001). MAFLD with fatigue was significantly associated with the presence and severity of steatosis and fibrosis by fibroscan ( P = <0.0001). By univariate and multivariate analysis: age, BMI, waist circumference, T2DM, hypertension, steatosis, fibrosis, and Fib-4 were considered risk factors for fatigue in the MAFLD group. The age, high social level, diabetes, hypertension, steatosis, fibrosis, and fib-4 were considered, by univariate and multivariate analysis, independent risk factors for depression in the MAFLD group. age, BMI, waist circumference, diabetes, hypertension, steatosis, fibrosis, and fib-4 were independent risk factors for sleep disorders in MAFLD. Fatigue, sleeping disorders, and depression are more prevalent in MAFLD patients than in the general population. The lower health utility scores in patients with MAFLD are associated with more advanced stages of the disease.

Investigation of anti-adhesion ability of 8-arm PEGNHS-modified porcine pericardium

In post-adhesion surgery, there is a clinical need for anti-adhesion membranes specifically designed for the liver, given the limited efficacy of current commercial products. To address this demand, we present a membrane suitable for liver surgery applications, fabricated through the modification of decellularized porcine pericardium with 20 KDa hexaglycerol octa (succinimidyloxyglutaryl) polyoxyethylene (8-arm PEGNHS). We also developed an optimized modification procedure to produce a high-performance anti-adhesion barrier. The modified membrane significantly inhibited fibroblast cell adherence while maintaining minimal levels of inflammation. By optimizing the modification ratio, we successfully controlled post-adhesion formation. Notably, the 8-arm PEG-modified pericardium with a molar ratio of 5 exhibited the ability to effectively prevent post-adhesion formation on the liver compared to both the control and Seprafilm®, with a low adhesion score of 0.5 out of 3.0. Histological analysis further confirmed its potential for easy separation. Furthermore, the membrane demonstrated regenerative capabilities, as evidenced by the proliferation of mesothelial cells on its surface, endowing anti-adhesion properties between the abdominal wall and liver. These findings highlight the membrane’s potential as a reliable barrier for repeated liver resection procedures that require the removal of the membrane multiple times.

Health-related quality of life over chemotherapy course among individuals with early-stage breast cancer: the association of social determinants of health and neighborhood socioeconomic disadvantage.

This study aimed to examine relationships between health-related quality of life (HRQOL), social determinants of health, and neighborhood socioeconomic disadvantage in individuals with early-stage breast cancer (ESBC) during chemotherapy. This is a longitudinal study that recruited Black and White women with ESBC receiving chemotherapy. Participants completed questionnaires recording their sociodemographic information at baseline and the Functional Assessment of Cancer Therapy-General (FACT-G) to report their HRQOL before each chemotherapy cycle. Linear mixed modeling was employed to examine the associations between FACT-G scores, self-reported race, and area deprivation index (ADI) before and at the last chemotherapy cycle, with the duration of chemotherapy treatment as a covariate. A total of 84 Black and 146 White women with ESBC completed the surveys. Linear mixed modeling results suggested that women with ESBC who reported being Black experienced significantly worse physical well-being than those who reported being White throughout chemotherapy, with a 0.22-point lower average (p = 0.02). Both Black and White women with ESBC experienced decreased functional well-being over the chemotherapy, and Black women consistently reported lower scores than White women, with the change in functional well-being over time differing between racial groups (p = 0.03). Participants' ADI national percentiles were not significantly associated with their HRQOL throughout chemotherapy. These findings underscore possible racial differences in some dimensions of HRQOL during chemotherapy among women with ESBC. Future research should consider further assessing life stressors and past experiences of discrimination and racism that may contribute to these disparities and guide proactive interventions.

Diffusion tensor imaging metrics as natural markers of multiple sclerosis-induced brain disorders with a low Expanded Disability Status Scale score

Non-invasive and effective differentiation along with determining the degree of deviations compared to the healthy cohort is important in the case of various brain disorders, including multiple sclerosis (MS). Evaluation of the effectiveness of diffusion tensor metrics (DTM) in 3T DTI for recording MS-related deviations was performed using a time-acceptable MRI protocol with unique comprehensive detection of systematic errors related to spatial heterogeneity of magnetic field gradients. In a clinical study, DTMs were acquired in segmented regions of interest (ROIs) for 50 randomly selected healthy controls (HC) and 50 multiple sclerosis patients. Identical phantom imaging was performed for each clinical measurement to estimate and remove the influence of systematic errors using the b-matrix spatial distribution in the DTI (BSD-DTI) technique. In the absence of statistically significant differences due to age in healthy volunteers and patients with multiple sclerosis, the existence of significant differences between groups was proven using DTM. Moreover, a statistically significant impact of spatial systematic errors occurs for all ROIs and DTMs in the phantom and for approximately 90 % in the HC and MS groups. In the case of a single patient measurement, this appears for all the examined ROIs and DTMs. The obtained DTMs effectively discriminate healthy volunteers from multiple sclerosis patients with a low mean score on the Expanded Disability Status Scale. The magnitude of the group differences is typically significant, with an effect size of approximately 0.5, and similar in both the standard approach and after elimination of systematic errors. Differences were also observed between metrics obtained using these two approaches. Despite a small alterations in mean DTMs values for groups and ROIs (1–3 %), these differences were characterized by a huge effect (effect size ∼0.8 or more). These findings indicate the importance of determining the spatial distribution of systematic errors specific to each MR scanner and DTI acquisition protocol in order to assess their impact on DTM in the ROIs examined. This is crucial to establish accurate DTM values for both individual patients and mean values for a healthy population as a reference. This approach allows for an initial reliable diagnosis based on DTI metrics.

The impact of burnout on over-the-counter counseling: a survey of community pharmacists in Vietnam

Abstract Background In many countries, self-medication is, in fact, the main service provided, exhausting pharmacist time and increasing their workload. However, there are currently no reports describing the impact of burnout on patient medication counseling. Objectives This study was conducted to determine the influence of burnout on over-the-counter (OTC) medication counseling services in Vietnam. Methods A cross-sectional study was conducted in community pharmacies across four districts in Can Tho City, Vietnam, between April and May 2023. Burnout was assessed using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), comprising three subscales: emotional exhaustion (EE; 9 items), depersonalization (DP; 5 items), and personal accomplishment (PA; 8 items). OTC medication counseling activities were evaluated using 12 questions. Results Of the 385 participants recruited, 22.3% reported high work intensity as a common factor contributing to burnout. Pharmacists with burnout had significantly lower medication counseling scores than those without burnout (mean = 4.35 vs. mean = 4.55, P = 0.005). Of the 12 OTC medication counseling activities, 6 activities, including inquiring about the recent medications used by the patient (P = 0.044), discouraging long-term medication use (P = 0.021), warning about the possibility of self-misdiagnosis (P &amp;lt; 0.001), warning about the possibility of the patient choosing the wrong treatment method (P = 0.001), providing advice on improving health (P = 0.005), and inquiring about allergies in the patient (P &amp;lt; 0.001), had significantly lower scores in pharmacists with burnout. Conclusions There was a significant negative association between burnout and medication counseling activities. Increasing staff numbers may be a useful solution for reducing work intensity, as this factor is reported to contribute the most to burnout among current pharmacists.

Systematic review of clinical practice guidelines for the diagnosis and management of retinal vein occlusion.

To assess the methodological quality of Clinical Practice Guidelines (CPG) for the diagnosis and management of Retinal Vein Occlusion (RVO). A systematic review of CPGs for the diagnosis and management of RVO was carried out with a search in databases, metasearch engines, CPG development institutions, ophthalmology associations and CPG repositories until April 2022. Search update was performed on April 2023, with no new record available. Five CPGs published in the last 10 years in English/Spanish were selected, and 5 authors evaluated them independently, using the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument. An individual assessment of each CPG by domain (AGREE-II), an overall assessment of the guide, and its use with or without modifications were performed. Additionally, a meta-synthesis of the recommendations for the most relevant outcomes was carried out. The lowest score (mean 18.8%) was for domain 5 'applicability', and the highest score (mean 62%) was for domain 4 'clarity of presentation'. The 2019 American guideline (PPP) presented the best score (40.4%) in domain 3 'rigour of development'. When evaluating the overall quality of the CPGs analysed, all CPGs could be recommended with modifications. In the meta-synthesis, anti-VEGF therapy is the first-choice therapy for macular oedema associated with RVO, but there is no clear recommendation about the type of anti-VEGF therapy to choose. Recommendations for diagnosis and follow-up are similar among the CPGs appraised. Most CPGs for the diagnosis and management of RVO have a low methodological quality assessed according to the AGREE-II. PPP has the higher score in the domain 'rigour of development'. Among the CPGs appraised, there is no clear recommendation on the type of anti-VEGF therapy to choose.

Relationship between night work and health-related quality of life: an analysis based on profiles and cumulative duration of exposure to night work among French workers in the CONSTANCES cohort.

The aim of this study is to estimate the association between night work and health-related quality of life (HRQoL) among French workers. The association between cumulative duration of night work and HRQoL was also investigated. Three career-long night work exposure groups were defined at inclusion in the CONSTANCES cohort: permanent night workers, rotating night workers and former night workers. Day workers with no experience of night work were the reference group. HRQoL was assessed using the Short Form Health Survey (SF-12), in particular the physical component summary (PCS) and mental component summary (MCS) scores, with a higher score indicating better HRQoL. Several linear regression models were built to test the association between night work exposure and HRQoL. The relationship between cumulative duration of night work and HRQoL scores was analyzed using generalised additive models. The sample consisted of 10,372 participants. Former night workers had a significantly lower PCS score than day workers (β [95% CI]: -1.09 [-1.73; -0.45], p = 0.001), whereas permanent night workers had a significantly higher MCS score (β [95% CI]: 1.19 [0.009; 2.36], p = 0.048). A significant decrease in PCS score from 5 to 20years of cumulative night work was observed among former night workers. Former night workers had poorer physical HRQoL in contrast to permanent and rotating night workers who had similar or even better HRQoL than day workers, suggesting the well-known healthy worker survivor effect. Consequently, both current and former night workers require regular and specific follow-up focused on the physical components of their health.

The Humanistic and Economic Burden Associated with Major Depressive Disorder: A Retrospective Cross-Sectional Analysis.

Major depressive disorder (MDD) is a debilitating and costly condition. This analysis characterized the health-related quality of life (HRQoL), health care resource utilization (HCRU), and costs between patients with versus without MDD, and across MDD severity levels. The 2019 National Health and Wellness Survey was used to identify adults with MDD, who were stratified by disease severity (minimal/mild, moderate, moderately severe, severe), and those without MDD. Outcomes included HRQoL (Short Form-36v2 Health Survey, EuroQol Five-Dimension Visual Analogue Scale, utility scores), HCRU (hospitalizations, emergency department [ED] visits, health care provider [HCP] visits), and annualized average direct medical and indirect (workplace) costs. A subgroup analysis was conducted in participants with MDD and prior medication treatment failure. Participant characteristics and study outcomes were evaluated using bivariate analyses and multivariable regression models, respectively. Cohorts comprised 10,710 participants with MDD (minimal/mild = 5905; moderate = 2206; moderately severe = 1565; severe = 1034) and 52,687 participants without MDD. Participants with MDD had significantly lower HRQoL scores than those without (each comparison, P < 0.001). Increasing MDD severity was associated with decreasing HRQoL. Relative to participants without MDD, participants with MDD reported more HCP visits (2.72 vs 5.64; P < 0.001) and ED visits (0.18 vs 0.22; P < 0.001) but a similar number of hospitalizations. HCRU increased with increasing MDD severity. Although most patients with MDD had minimal/mild to moderate severity, total direct medical and indirect costs were significantly higher for participants with versus without MDD ($8814 vs $6072 and $5425 vs $3085, respectively, both P < 0.001). Direct and indirect costs were significantly higher across all severity levels versus minimal/mild MDD (each comparison, P < 0.05). Among patients with prior MDD medication treatment failure (n = 1077), increasing severity was associated with significantly lower HRQoL and higher total indirect costs than minimal/mild MDD. These results quantify the significant and diverse burdens associated with MDD and prior MDD medication treatment failure.

Combined balloon Eustachian tuboplasty/endoscopic sinus surgery for patients with chronic rhinosinusitis and Eustachian tube dysfunction.

To elucidate the role of balloon Eustachian tuboplasty (BET) in the management of chronic rhinosinusitis with obstructive Eustachian tube dysfunction (ETD), we evaluated the results of endoscopic sinus surgery (ESS) with and without BET in patients with chronic rhinosinusitis with obstructive ETD. This randomized controlled trial conducted in a single-institution tertiary care center setting included 50 patients diagnosed with primary chronic rhinosinusitis and obstructive ETD between July 2018 and June 2022. Twenty-five patients were prospectively enrolled for combined ESS/BET. The control group (25 patients) underwent ESS alone. Outcome measurements of the Sinonasal Outcome Test 22,modified Lund-Kennedy score, Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), and serial Eustachian tube function test results were analyzed 3 months postoperatively. The improvement (12.60±6.50) in the ETDQ-7 score in the BET group was significantly higher than that in the control group (6.60±5.58). The ratio of improvement in the ETDQ-7 score was also significantly higher in the BET than in the control group (92%vs. 68%, p=0.034). Logistic regression analysis showed that performing BET (odds ratio [OR]: 5.41, 95% confidence interval [CI]: 1.02-28.79, p=0.048) and a low post-modified Lund-Kennedy score (OR: 0.15, 95% CI: 0.04-0.54, p=0.004) were significantly associated with ETDQ-7 score improvement. Combined BET/ESS could decrease otologic symptoms and improve Eustachian tube function. BET may be an appropriate adjunctive procedure for treating chronic rhinosinusitis with obstructive ETD.

Propensity matched analysis of minimally invasive and open radical resection for rectal cancer: comparison of short-term outcomes in elderly/frail patients.

Although minimally invasive surgery (MIS), such as robotic and laparoscopic procedures, is sometimes a better option than open surgery for patients with rectal cancer, it can present challenges for some elderly or frail patients who have a higher risk of chronic illnesses and poor surgical tolerance. On the basis of several pathophysiological characteristics, the patients were grouped according to their age. The time nodes, which are 65 and 80years old, can clarify the goal of the study and offer some therapeutic benefit. These subgroups stand to gain a great deal from MIS because of its superior arm of machinery and imagery. The short-term oncological outcomes and postoperative conditions of robotic surgery, laparoscopic surgery, and conventional open surgery were compared in this study using a propensity-matched analysis. In this retrospective study, a total of 2049 consecutive patients who underwent proctectomy between September 2017 and June 2023 were chosen. We then carried out a propensity matching analysis based on inclusion criteria. Patients were split into two age groups: 65-80 and > 80. While the secondary objective was to further investigate the similar characteristics between RS and LS, the major objective was to compare oncological outcomes and postoperative conditions between MIS and OS. K-M survival curves were used to represent oncological outcomes and survival conditions. Complication rate and mFI score were used to assess postoperative conditions. Regarding the functional outcomes, the LARS scale was applied to create questionnaires that calculated the anal function of the patients. 110 cases from the group of patients aged 65-80 were successfully merged after matching 1: 1 by propensity score, whereas 73 instances from patients aged > 80 were incorporated while examining the primary objective between OS and MIS. Regarding the secondary goal, each group contained 45 cases for patients above 80 and 65 cases for patients aged 65-80, respectively. Faster recovery from MIS included quicker first flatus passage, earlier switch to liquid nutrition, and shorter hospital stay. In the meantime, MIS also showed benefits in terms of the proportion of low mFI scores and the rates of wound complications in the two age groups. Less blood loss and shorter operational time are further MIS features. On the other hand, MIS experienced more pulmonary complications than OS. Robotic surgery was statistically no different from laparoscopic surgery in patients aged 65-80, although it was superior in terms of operative time and recovery. Comparable and satisfactory oncological and survival results were obtained with all three treatments. For elderly/frail patients with rectal cancer, MIS could be recognized as an effective procedure with favorable outcomes of recovery that are accompanied by better postoperative conditions. While, robotic surgery is slightly better than laparoscopic surgery in some aspects. However, to further demonstrate the effectiveness of three surgical modalities in treating certain groups, multi-center prospective studies are required.

Neuraxial clonidine is not associated with lower post-cesarean opioid consumption or pain scores in parturients on chronic buprenorphine therapy: a retrospective cohort study.

Adequate post-cesarean delivery analgesia can be difficult to achieve for women diagnosed with opioid use disorder receiving buprenorphine. We sought to determine if neuraxial clonidine administration is associated with decreased opioid consumption and pain scores following cesarean delivery in women receiving chronic buprenorphine therapy. This was a retrospective cohort study at a tertiary care teaching hospital of women undergoing cesarean delivery with or without neuraxial clonidine administration while receiving chronic buprenorphine. The primary outcome was opioid consumption (in morphine milligram equivalents) 0-6h following cesarean delivery. Secondary outcomes included opioid consumption 0-24h post-cesarean, median postoperative pain scores 0-24h, and rates of intraoperative anesthetic supplementation. Multivariable analysis evaluating the adjusted effects of neuraxial clonidine on outcomes was conducted using linear regression, proportional odds model, and logistic regression separately. 196 women met inclusion criteria, of which 145 (74%) received neuraxial clonidine while 51 (26%) did not. In univariate analysis, there was no significant difference in opioid consumption 0-6h post-cesarean delivery between the clonidine (8 [IQR 0, 15]) and control (1 [IQR 0, 8]) groups (P = 0.14). After adjusting for potential confounders, there remained no significant association with neuraxial clonidine administration 0-6h (Difference in means 2.77, 95% CI [-0.89 to 6.44], P = 0.14) or 0-24h (Difference in means 8.56, 95% CI [-16.99 to 34.11], P = 0.51). In parturients receiving chronic buprenorphine therapy at the time of cesarean delivery, neuraxial clonidine administration was not associated with decreased postoperative opioid consumption, median pain scores, or the need for intraoperative supplementation.

Demographic, biochemical, clinical,and cognitivesymptomdifferences between smokersandnon-smokersin Chineseoldermale patients with chronic schizophrenia.

Several studies have suggested that smoking may impair cognitive function and worsen psychiatric symptoms in people with schizophrenia, but the results have not been consistent. There have been few studies to date that have examined the effects of smoking in older men with chronic schizophrenia. The participants in our study consisted of 167 order Chinese males with chronic schizophrenia and 359 normal control subjects. We split them into smoking and non-smoking groups based on whether or not they smoked. Second, we compared their differences in terms of general demographic characteristics (such as age, education, body mass index, age of illness onset, and course of disease), disease information (such as hypertension, diabetes, and hyperlipidemia), lifestyle factors (such as physical exercise and lunch break), blood biochemical indicators (such as albumin, triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein and fasting blood glucose), and medication usage (such as clozapine, olanzapine, risperidone, and chlorpromazine). Lastly, a neuropsychologicaltestbattery was used to assess their psychiatric and cognitive symptoms, for example, the Montreal Cognitive Assessment (MoCA) was used to assess their overall cognitive functioning. Their depressive symptoms were assessed by the geriatric depression scale (GDS). Activities of daily living (ADL) were used to assess their ability to lead a daily life, while the positive and negative syndrome scales (PANSS) were used to assess their psychiatric symptoms. Smokers who develop schizophrenia at older ages had a higher body mass index than non-smokers. We also found that plasma albumin, triglycerides, low-density lipoprotein, and fasting blood glucose concentrations were significantly higher in smokers. In contrast, smokers with schizophrenia also had lower PANSS total scores, negative symptom scores, and general psychopathology scores. A forward stepwise binary logistics regression analysis demonstrated a significant association between negative symptom scores and smoking status (B = 0.112, p < 0.001, OR = 1.119, 95% confidence interval: 1.059-1.181). Correlation analysis was carried out and it was found that the amount of cigarette consumption per day had a negative correlation with plasma albumin level(r = -0.290, p = 0.004). However, no such association was found in normal controls. Elderly Chinese men with schizophrenia have a higher percentage of smokers, and although smoking can reduce their plasma albumin levels, it does contribute to the prevention of negative symptoms.

Functional outcome and analysis of factors affecting health-related quality of life of surgically managed pelvic ring fractures: a cross-sectional study.

Pelvic ring fractures, particularly those involving the posterior pelvis, pose significant challenges due to their inherent instability. The posterior pelvic ring is critical in providing structural support and stability to the pelvis. This study evaluates the functional outcomes and health-related Quality of life (HRQOL) of patients who underwent internal fixation for unstable pelvic fractures. Various factors influencing the outcomes are also investigated. A single-center cross-sectional study was conducted on patients with unstable sacral fractures treated with posterior tension band plate or sacroiliac plating with or without symphyseal plating between 2016 and 2020. Patient demographics, injury mechanisms, associated injuries, surgical details, complications, and return-to-work data were collected. HRQOL was assessed using specific pelvic fracture instruments and general HRQOL questionnaires. Logistic regression analysis was performed to identify factors associated with lower SF-12 and SF-36 scores RESULTS: The study included 54 patients, predominantly males (55.6%), aged 18-70 years, with high-energy trauma mechanisms, such as road traffic accidents and occupational injuries. The majority of patients had lateral compression pelvic fractures. Overall, the functional outcomes were favorable, with excellent or good outcomes observed in 86.1% of cases. Patients with associated injuries, such as abdominal, chest, or head injuries, were likelier to have lower SF-12 physical component scores. Sexual satisfaction scores remained stable for most patients post-surgery. This study highlights the favorable functional outcomes and HRQOL for patients undergoing fixation for unstable pelvic ring fractures. Younger, working-age males were the most commonly affected demographic. Associated injuries significantly affected physical HRQOL scores. Despite high-energy trauma, patients generally reported satisfactory sexual function post-surgery.

Progressive coronal caudal curve after corrective osteotomies for congenital cervicothoracic scoliosis: incidence and predictors.

Postoperative progressive coronal caudal curve (PCC) was characterized by a postoperative de novo caudal S-curve ≥ 20° following congenital cervicothoracic scoliosis (CTS) corrective osteotomies, and at least 20° greater than the preoperative measurement, while the incidence was uncertain and the pathogenesis was equivocal. The objective of this study was to investigate the morbidity and potential factors contributing to PCC following CTS surgery. This study reviewed 72 CTS patients between 2005 and 2021. Patients were categorized into two groups according to the absence or presence of PCC at last follow-up, namely the nonprogressive curve group (NPC-group) and the progressive curve group (PC-group). Demographics, radiographic data and the Scoliosis Research Society-22 (SRS-22) questionnaire results were reviewed. Multivariate linear regression analyses were utilized to determine possible predictors for PCC. PCC was observed in 11 (15%) of the total 72 patients. Compared with the NPC-group, the PC-group exhibited greater postoperative residual local curve (24.0 ± 9.7° vs. 9.1 ± 4.4°, P < 0.001), upper instrumented vertebra (UIV) tilt (16.9 ± 7.4° vs. 6.2 ± 3.7°, P < 0.001), T1 tilt (14.3 ± 9.4° vs. 6.6 ± 3.9°, P = 0.022) and neck tilt (10.1 ± 6.7° vs. 3.7 ± 2.5, P = 0.009). The multivariable linear regression demonstrated that the larger postoperative UIV tilt, residual local curve and neck tilt were associated with PCC. In addition, patients with PCC showed lower SRS-22 scores in terms of pain, mental health, self-image and satisfaction (P < 0.05). The morbidity of PCC was 15% in CTS patients who underwent corrective osteotomies. Greater residual local curve, postoperative UIV tilt and neck tilt were identified as predictors for PCC.

Performance of a commercially available Generative Pre-trained Transformer (GPT) in describing radiolucent lesions in panoramic radiographs and establishing differential diagnoses.

To evaluate the performance of a commercially available Generative Pre-trained Transformer (GPT) in describing and establishing differential diagnoses for radiolucent lesions in panoramic radiographs. Twenty-eight panoramic radiographs, each containing a single radiolucent lesion, were evaluated in consensus by three examiners and a commercially available ChatGPT-3.5 model. They provided descriptions regarding internal structure (radiodensity, loculation), periphery (margin type, cortication), shape, location (bone, side, region, teeth/structures), and effects on adjacent structures (effect, adjacent structure). Diagnostic impressions related to origin, behavior, and nature were also provided. The GPT program was additionally prompted to provide differential diagnoses. Keywords used by the GPT program were compared to those used by the examiners and scored as 0 (incorrect), 0.5 (partially correct), or 1 (correct). Mean score values and standard deviation were calculated for each description. Performance in establishing differential diagnoses was assessed using Rank-1, -2, and - 3. Descriptions of margination, affected bone, and origin received the highest scores: 0.93, 0.93, and 0.87, respectively. Shape, region, teeth/structures, effect, affected region, and nature received considerably lower scores ranging from 0.22 to 0.50. Rank-1, -2, and - 3 demonstrated accuracy in 25%, 57.14%, and 67.85% of cases, respectively. The performance of the GPT program in describing and providing differential diagnoses for radiolucent lesions in panoramic radiographs is variable and at this stage limited in its use for clinical application. Understanding the potential role of GPT systems as an auxiliary tool in image interpretation is imperative to validate their clinical applicability.

Machine learning-based cell death signature for predicting the prognosis and immunotherapy benefit in stomach adenocarcinoma.

Stomach adenocarcinoma (STAD) is a one of most common malignancies with high mortality-to-incidence ratio. Programmed cell death (PCD) exerts vital functions in the progression of cancer. The role of PCD-related genes (PRGs) in STAD are not fully clarified. Using TCGA, GSE15459, GSE26253, GSE62254 and GSE84437 datasets, PCD-related signature (PRS) was constructed with an integrative procedure including 10 machine learning methods. The role of PRS in predicting the immunotherapy benefits was evaluated by several predicting score and 3 immunotherapy datasets (GSE91061, GSE78220, and IMvigor210). The model developed by Lasso + CoxBoost algorithm having a highest average C-index of 0.66 was considered as the optimal PRS. As an independent risk factor for STAD patients, PRS had a good performance in predicting the overall survival rate of patients, with an AUC of 1-, 3-, and 5-year ROC curve being 0.771, 0.751 and 0.827 in TCGA cohort. High PRS score demonstrated a lower gene set score of some immune-activated cells and immune-activated activities. Patient with high PRS score had a higher TIDE score, higher immune escape score, lower PD1&CTLA4 immunophenoscore, lower TMB score, lower response rate and poor prognosis, indicating a less immunotherapy response. The IC50 value of some drugs correlated with chemotherapy and targeted therapy was higher in high PRS score group. Our investigation developed an optimal PRS in STAD and it acted as an indicator for predicting the prognosis, stratifying risk and guiding treatment for STAD patients.

Freezing of gait in idiopathic normal pressure hydrocephalus

BackgroundReports of freezing of gait (FoG) in idiopathic normal pressure hydrocephalus (iNPH) are few and results are variable. This study’s objective was to evaluate the frequency of FoG in a large cohort of iNPH patients, identify FoG-associated factors, and assess FoG’s responsiveness to shunt surgery.MethodsVideotaped standardized gait protocols with iNPH patients pre- and post-shunt surgery (n = 139; median age 75 (71–79) years; 48 women) were evaluated for FoG episodes by two observers (Cohens kappa = 0.9, p < 0.001). FoG episodes were categorized. Mini-mental state examination (MMSE) and MRI white matter hyperintensities (WMH) assessment using the Fazekas scale were performed. CSF was analyzed for Beta-amyloid, Tau, and Phospho-tau. Patients with and without FoG were compared.ResultsTwenty-two patients (16%) displayed FoG at baseline, decreasing to seven (8%) after CSF shunt surgery (p = 0.039). The symptom was most frequently exhibited during turning (n = 16, 73%). Patients displaying FoG were older (77.5 vs. 74.6 years; p = 0.029), had a slower walking speed (0.59 vs. 0.89 m/s; p < 0.001), a lower Tinetti POMA score (6.8 vs. 10.8; p < 0.001), lower MMSE score (21.3 vs. 24.0; p = 0.031), and longer disease duration (4.2 vs. 2.3 years; p < 0.001) compared to patients not displaying FoG. WMH or CSF biomarkers did not differ between the groups.ConclusionsFoG is occurring frequently in iNPH patients and may be considered a typical feature of iNPH. FoG in iNPH was associated with higher age, longer disease duration, worse cognitive function, and a more unstable gait. Shunt surgery seems to improve the symptom.

Prognostic factors for tracheostomy early decannulation in acquired brain injury patients.

After severe brain injuries, a tracheostomy tube is usually inserted for respiratory support. This study aimed to clarify the prognostic factors for tracheostomy early decannulation in patients with acquired brain injuries. We retrospectively reviewed the medical records of inpatients with acquired brain injuries who underwent successful tracheostomy decannulation between March 2021 and June 2022. Fifty-six patients were included; median age was 68 (59-72) years; 28 (50%) were men; 28 (50%) underwent tracheostomy due to stroke. The median time to decannulation was 47 days. The patients were divided into the early and the late decannulation groups based on the median time, and compared. In univariate analysis, the early decannulation group had a higher BMI, peak cough flow, and acquired brain injuries due to trauma, and a lower penetration-aspiration scale score, duration of antibiotic use, and duration of oxygen use. Multivariate Cox regression analysis revealed that a higher initial peak cough flow [hazard ratio (HR) 1.142; 95% confidence interval (CI) 0.912-0.954; P < 0.001] and lower duration of oxygen use (HR 0.930; 95% CI 0.502-0.864; P = 0.016) were independent factors for early tracheostomy decannulation, with each unit increase in peak cough flow corresponding to a 14.2% increase and each additional day of duration of oxygen use corresponding to a 7.0% decrease in the likelihood of early decannulation. In conclusion, key prognostic factors for early tracheostomy decannulation were identified as the initial cough strength and duration of oxygen use. These results could play important role in decannulation plans for patients with tracheostomy tube.

Ranking of immunization programs in Latin America, 2020Ranking dos programas de vacinação na América Latina, 2020

Construct a ranking of national immunization programs in Latin America in 2020 and compare it with the previous year. Eighteen national immunization programs were evaluated on the basis of public information obtained from official sites of the countries' ministries of health, the World Health Organization, the Pan American Health Organization, the United Nations Children's Fund, and local sources. The ranking was based on the 2020 vaccination schedule for different life stages, special situations, vaccination against influenza, 2019 vaccination coverage, and programmatic aspects. Vaccination coverage decreased in most countries. The average regional declined in 2020, as did the scores for most countries, except Chile and Colombia. Chile leads the ranking, followed by Uruguay, Panama, and Costa Rica. Chile stands out for its full calendar, higher vaccination coverage rates, and programmatic achievements. The lower overall score in 2020 highlights the need to recover the Region's vaccination coverage rates. This analysis seeks to motivate countries to address pending challenges.
