Relationship between thyroid hormone levels and metabolic dysfunction associated steatotic liver disease in patients with type 2 diabetes: A clinical study.

This study investigates the correlation between thyroid hormone levels and metabolic dysfunction in patients with type 2 diabetes mellitus (T2DM) who exhibit normal thyroid function and metabolic dysfunction associated with steatotic liver disease (MASLD). The objective is to identify a scientific basis for the management of T2DM complicated by MASLD, aiming to refine clinical strategies and enhance patient well-being. Statistical analysis was conducted using SPSS 26.0, employing independent sample t-tests for normally distributed data and logarithmic transformations for non-normal data to meet analysis prerequisites. Multifactorial logistic regression analysis elucidated the impact of various factors on the risk of MASLD in T2DM patients. Elevated levels of FT3 may be associated with an increased risk of nonalcoholic fatty liver disease. Additionally, the FT3/FT4 ratio has been validated as an effective serological marker for predicting the risk of MASLD. In patients with DM2 and normal thyroid function, changes in thyroid hormone levels are closely related to the occurrence of MASLD. Elevated levels of FT3, total triiodothyronine (TT3), and thyroid-stimulating hormone are associated with an increased risk of MASLD. FT3, TT3, and thyroid-stimulating hormone have important clinical value in the diagnosis of patients with T2DM complicated with MASLD.

Generation of wine sensory descriptors by one-step method based on free profile and their use to establish the typicity of PDO wines

The typicity of wines is related to their sensory characteristics, which allow them to be differentiated from other wines. Different sensory methods have been applied to try to detect the sensory characteristics responsible for the typicity of Protected Designation of Origin wines (PDO). However, so far, none of them has been completely successful. In this study, a new one-step method based on free profile and comparative analysis by pairs was applied to generate sensory descriptors of wines. The discriminant power of the sensory attributes generated among wines from 4 different PDO wines from the Spanish Autonomous Community of Castilla y León was evaluated. The study was carried out with wine experts and 159 white, rosé, and red wines were tasted. The judges generated 245 attributes which were reduced to 95 (11 defects, 20 visual, 48 olfactory and 16 taste and mouthfeel). A Multifactorial Analysis was carried out with the data of contingency matrices based on the frequency of citation. The results obtained showed that the sensory descriptors generated allowed the wines to be distinguished according to their origin, being the discriminant power significantly higher when the visual, olfactory and gustatory attributes were considered separately.

Analysis of lymph node metastasis and survival prognosis in early gastric cancer patients: A retrospective study.

Early gastric cancer (EGC) is a common malignant tumor of the digestive system, and its lymph node metastasis and survival prognosis have been concerning. By retrospectively analyzing the clinical data of EGC patients, we can better understand the status of lymph node metastasis and its impact on survival and prognosis. To evaluate the prognosis of EGC patients and the factors that affect lymph node metastasis. The clinicopathological data of 1011 patients with EGC admitted to our hospital between January 2015 and December 2023 were collected in a retrospective cohort study. There were 561 males and 450 females. The mean age was 58 ± 11 years. The patient underwent radical gastrectomy. The status of lymph node metastasis in each group was determined according to the pathological examination results of surgical specimens. The outcomes were as follows: (1) Lymph node metastasis in EGC patients; (2) Analysis of influencing factors of lymph node metastasis in EGC; and (3) Analysis of prognostic factors in patients with EGC. Normally distributed measurement data are expressed as mean ± SD, and a t test was used for comparisons between groups. The data are expressed as absolute numbers or percentages, and the chi-square test was used for comparisons between groups. Rank data were compared using a nonparametric rank sum test. A log-rank test and a logistic regression model were used for univariate analysis. A logistic stepwise regression model and a Cox stepwise regression model were used for multivariate analysis. The Kaplan-Meier method was used to calculate the survival rate and construct survival curves. A log-rank test was used for survival analysis. Analysis of influencing factors of lymph node metastasis in EGC. The results of the multifactor analysis showed that tumor length and diameter, tumor site, tumor invasion depth, vascular thrombus, and tumor differentiation degree were independent influencing factors for lymph node metastasis in patients with EGC (odds ratios = 1.80, 1.49, 2.65, 5.76, and 0.60; 95%CI: 1.29-2.50, 1.11-2.00, 1.81-3.88, 3.87-8.59, and 0.48-0.76, respectively; P < 0.05). Analysis of prognostic factors in patients with EGC. All 1011 patients with EGC were followed up for 43 (0-13) months. The 3-year overall survival rate was 97.32%. Multivariate analysis revealed that age > 60 years and lymph node metastasis were independent risk factors for prognosis in patients with EGC (hazard ratio = 9.50, 2.20; 95%CI: 3.31-27.29, 1.00-4.87; P < 0.05). Further analysis revealed that the 3-year overall survival rates of gastric cancer patients aged > 60 years and ≤ 60 years were 99.37% and 94.66%, respectively, and the difference was statistically significant (P < 0.05). The 3-year overall survival rates of patients with and without lymph node metastasis were 95.42% and 97.92%, respectively, and the difference was statistically significant (P < 0.05). The lymph node metastasis rate of EGC patients was 23.64%. Tumor length, tumor site, tumor infiltration depth, vascular cancer thrombin, and tumor differentiation degree were found to be independent factors affecting lymph node metastasis in EGC patients. Age > 60 years and lymph node metastasis are independent risk factors for EGC prognosis.

Differential diagnosis and nosology issues of disorders with affective and psychotic symptoms: a clinical case report

Based on the results of large-scale genomic studies, the psychotic continuum hypothesis suggests considering disorders characterized by primary psychotic symptoms as part of a single spectrum of neurodevelopmental disorders and implies the existence of a gradient of severity between affective disorders and schizophrenia, with increasing severity of psychotic episodes and deficits. The continuum hypothesis explains the existence of the previously controversial diagnosis of schizoaffective disorder (SAD), which combines clinical manifestations of both schizophrenia and bipolar affective disorder: according to this hypothesis, schizoaffective disorder is assigned an intermediate position in the continuum. The common leading clinical criteria and genetic commonality on the one hand, and the absence of objective disease markers on the other significantly complicate the diagnostic search between the disorders with affective and psychotic symptoms, raising questions not only about their nosological relationships but also about the problem of finding methods of differentiation at early stages of disorder development. Promising tools for differential diagnosis include multifactorial analysis of parameters (genetic, clinical, and socio-demographic parameters, level of social functioning, response to prescribed psychopharmacotherapy), molecular phenotyping of profiles, and the search for laboratory, neuroimaging, and neurobiological markers of diseases. As of today, the main reliable approach in the differential diagnosis of these disorders remains the follow-up approach. The article presents a clinical case describing a 19-year follow-up of a patient with clinically heterogeneous episodes of affective-delusional symptomatology combined with alcoholism and demonstrating the difficulty of diagnosing disorders with affective and psychotic manifestations, as well as the need for further research in this area.

Factors associated with frozen shoulder in adults: a retrospective study

ObjectiveThis study aims to explore the risk factors associated with frozen shoulder patients and further analyze the relationship between gender and diabetes with frozen shoulder.MethodWe have reviewed the data of 1205 frozen shoulder patients in China's Xinjiang region from 2018 to 2023. The collected information included patients' gender, occupation, place of origin, marital status, age, the season of disease onset, duration of illness, etiology, surgical history, hypertension, diabetes, respiratory diseases, knee joint disease, hyperlipidemia, cardiovascular diseases, cervical spondylosis, lumbar disc herniation, rheumatoid arthritis, hyperuricemia, sleep quality, smoking and alcohol consumption, and constipation. We have used multifactor logistic regression analysis to identify the risk factors for a frozen shoulder.ResultsSingle-factor logistic regression analysis showed that the number of females, patients with diabetes, knee joint disease, constipation, and patients with poor sleep quality in the observation group are higher than in the control group (P < 0.05). There were no statistically significant differences between the two groups in terms of occupation, place of origin, marital status, age, season of disease onset, duration of illness, etiology, surgical history, hypertension, respiratory diseases, hyperlipidemia, cardiovascular diseases, cervical spondylosis, lumbar disc herniation, rheumatoid arthritis, hyperuricemia, smoking, and alcohol consumption history (P > 0.05).Multivariate analysis showed that the final model included four variables: gender, diabetes history, sleep, and constipation. Among them, the OR values of gender and diabetes history were more significant than 1, indicating that they were independent risk factors for frozen shoulder, while the OR values of sleep and constipation were less than 1, suggesting that they were negatively associated with the occurrence of frozen shoulder.ConclusionThe results of this study suggest that gender and diabetes are independent risk factors for frozen shoulder. Additionally, poor sleep quality and constipation also can be correlated with the occurrence of a frozen shoulder.

Relationship between carotid atherosclerosis and lipoprotein (a) in patients with acute ischemic stroke.

This study aimed to examine the relationship between lipoprotein (a) (Lp[a]) and other blood lipid indexes and carotid artery atherosclerosis in patients with acute ischemic stroke (AIS). A total of 2,018 patients were selected from the hospital "acute stroke intervention and secondary prevention registration database" by identifying blood fat indexes (cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and Lp[a]). Based on the results of carotid artery ultrasound examinations, the patients were divided into a "no plaque" group, comprising 400 patients, a "plaque and no stenosis" group, comprising 1,122 patients and a "carotid stenosis" group, comprising 496 patients. The relationship between Lp(a) and blood lipid indexes and carotid artery atherosclerosis was then investigated using multi-factor logistics regression analysis. There were 400 patients (19.8%) with no carotid plaque, 1,122 patients (55.6%) with plaque and no carotid stenosis and 496 patients (24.6%) with carotid stenosis. As the degree of carotid artery atherosclerosis increased, the Lp(a) level gradually increased; Lp(a) and cholesterol were identified as independent risk factors for carotid atherosclerosis. Lipoprotein (a) and cholesterol are independent risk factors for patients with AIS with carotid atherosclerosis, and their levels increase with the degree of carotid artery atherosclerosis; therefore, attention should focus on levels of cholesterol and Lp(a) in acute stroke patients to control atherosclerosis effectively.

Development and validation of a model for predicting the early occurrence of RF in ICU-admitted AECOPD patients: a retrospective analysis based on the MIMIC-IV database

BackgroundThis study aims to construct a model predicting the probability of RF in AECOPD patients upon hospital admission.MethodsThis study retrospectively extracted data from MIMIC-IV database, ultimately including 3776 AECOPD patients. The patients were randomly divided into a training set (n = 2643) and a validation set (n = 1133) in a 7:3 ratio. First, LASSO regression analysis was used to optimize variable selection by running a tenfold k-cyclic coordinate descent. Subsequently, a multifactorial Cox regression analysis was employed to establish a predictive model. Thirdly, the model was validated using ROC curves, Harrell’s C-index, calibration plots, DCA, and K-M curve.ResultEight predictive indicators were selected, including blood urea nitrogen, prothrombin time, white blood cell count, heart rate, the presence of comorbid interstitial lung disease, heart failure, and the use of antibiotics and bronchodilators. The model constructed with these 8 predictors demonstrated good predictive capabilities, with ROC curve areas under the curve (AUC) of 0.858 (0.836–0.881), 0.773 (0.746–0.799), 0.736 (0.701–0.771) within 3, 7, and 14 days in the training set, respectively and the C-index was 0.743 (0.723–0.763). Additionally, calibration plots indicated strong consistency between predicted and observed values. DCA analysis demonstrated favorable clinical utility. The K-M curve indicated the model’s good reliability, revealed a significantly higher RF occurrence probability in the high-risk group than that in the low-risk group (P < 0.0001).ConclusionThe nomogram can provide valuable guidance for clinical practitioners to early predict the probability of RF occurrence in AECOPD patients, take relevant measures, prevent RF, and improve patient outcomes.

A Cohort Study of Serum 25-Hydroxyvitamin D Levels and Lung Disease in Preterm Infants

Objectives: To analyze the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels and lung diseases (wet lung, RDS, BPD, pneumothorax) in preterm infants. Methods: Preterm infants (corrected gestational age &lt;37 weeks) hospitalized in the neonatology department of Yan'an University Hospital from January 2023 to December 2023 were selected as the study subjects, and their clinical data and 25-hydroxyvitamin D [25(OH)D] levels in the first 24 h of life were collected (by the random number table method to avoid selection bias) in a retrospective cohort study with the basis of the Serum 25(OH)D level was used to categorize preterm infants into high vitamin D and low vitamin D groups, and to compare the incidence of lung diseases in preterm infants in the 2 groups. Results: A total of 414 preterm infants were selected, and 237 preterm infants were finally included for analysis. The mean serum 25(OH)D level in preterm infants within 24 hours of birth was 16.97 ng/mL. 140 cases in the low-vitamin D group had a serum 25(OH)D level of (11.88± 2.74) ng/mL. 97 cases in the high-vitamin D group had a serum 25(OH)D level of (24.31± 7.52) ng/mL; the rate of births in the fall in the low-vitamin D group was was significantly higher than that of the high-vitamin D group (P&lt;0.05), the utilization rate of lung surface active substance was higher than that of the high-vitamin D group (P&lt;0.05), and the incidence of RDS and BPD was significantly higher than that of the high-vitamin D group (P&lt;0.05). Univariate logistic regression analysis suggested that season of birth, serum 25(OH)D level, 5 min Apgar score and prenatal hormone use were associated with pulmonary complications in preterm infants (P&lt;0.05). Multifactorial logistic regression analysis showed that higher serum 25(OH)D levels reduced the risk of pulmonary complications in preterm infants, which was statistically significant (B=-0.056, RR= 0.946, 95% CI: 0.910-0.984, P=0.006); higher 5-min Apgar scores had a lower incidence of pulmonary complications in preterm infants, which was statistical significance (B=-0.722, RR= 0.486, 95% CI: 0.281~0.840, P=0.010); prenatal use of hormones will reduce the risk of pulmonary complications in preterm infants (B=-0.763, RR= 0.466, 95% CI: 0.261~0.833, P=0.010). Conclusion: Low vitamin D levels at birth in preterm infants may increase the incidence of RDS and BPD.

Survival Patterns Based on First-site–specific Visceral Metastatic Prostate Cancer: Are Outcomes of Visceral Metastases the Same?

Background and objectiveVisceral metastatic disease in prostate cancer patients conveys a poor prognosis. Using advanced imaging techniques, studies have demonstrated increasing detection rates of visceral metastasis. Visceral metastases are now seen in up to 30–60% of prostate cancer patients. Survival patterns of site-specific visceral metastasis are described poorly in the literature. Here, we sought to investigate survival patterns in prostate cancer patients according to their first detected site of visceral metastasis. MethodsRetrospectively, we identified 203 prostate cancer patients with visceral metastases from the Mayo Clinic Advanced Prostate Cancer Registry. Patients were divided into three groups according to the first site of visceral metastases detected: lung, brain, or liver. Visceral metastases were detected primarily on either metabolic imaging (C-11 choline) or prostate-specific membrane antigen positron emission tomography computed tomography (CT) scan. Confirmation of visceral metastasis diagnosis was established with either biopsy when feasible or focused conventional imaging, including focused CT or magnetic resonance imaging. Overall survival and cancer-specific survival were estimated using the Kaplan-Meier method. Univariate and multivariate Cox regression model was conducted to assess different variables that affect overall and cancer-specific survival. Key findings and limitationsOver a median (interquartile range) follow-up duration of 16.2 (3.9–49.8) mo, the overall and cancer-specific survival of the entire cohort suggests better survival patterns in patients with first-site lung metastases than in patients with first-site brain or liver metastases (p < 0.0001). In univariate and multivariate analyses of factors impacting patients’ overall and cancer-specific survival, a high prostate-specific antigen level at diagnosis of visceral metastasis, concomitant bone and lymph node disease, and more than four visceral metastases were associated with poor overall and cancer-specific survival (p < 0.05). On the contrary, first-site lung metastasis was associated with improved overall and cancer-specific survival, compared with first-site liver and brain metastases (p < 0.001). Conclusions and clinical implicationsThese data suggest that prostate cancer patients with visceral metastatic disease have varying survival patterns according to first-site detected visceral metastasis. In our cohort, patients with first-site lung metastasis demonstrated better survival outcomes than patients with first-site brain or liver metastasis. Patient summaryOur study explored the survival outcomes among patients with visceral metastatic prostate cancer employing cutting-edge imaging methods. Prostate cancer patients with metastases to different organs have different survival rates. Patients with cancer spreading to the lungs first showed better survival than those with cancer spreading to the brain or liver first.

Analysis of multi-factors affecting resource consumption efficiency in Vietnam

Theprimary objective of this study is todelve into the factors potentially influencing resource utilisationefficiency at the provincial level in Vietnam. We leverage 185 data points gathered from 63 Vietnamese cities or provinces, obtained from two key sources: the General Statistical Office of Vietnam and the Ministry of Information and Communications Vietnam. The collected data was subjected to analysis using an empirical econometric model that incorporates time-series characteristics to explore the connections between these potential determinants of resource consumption efficiency. The analysis revealed a strong correlation between resource utilisationefficiency and the quality of digital transformation, logistics performance, and various aspects of public governance,including accountability to higher authorities, control of corruption, administrative procedures, and public service delivery. Additionally, the provincial competitiveness index, encompassing factors like entry costs, policy bias, and labourpolicy, also demonstrated a significant association. These findings highlight a clear link between effective public governance and efficient resource utilisationin Vietnamese provinces. This suggests that robust public governance systems, combined with advancements in digitalisationand logistics, can play a crucial role in optimisingresource utilisationwithin Vietnamese provinces.

Dry eye and decreased tear film stability in primary acquired nasolacrimal duct obstruction patients.

Exploring the prevalence of dry eye (DE) and the changes of tear film stability in patients with primary acquired obstruction of the nasolacrimal duct (PANDO). In this cross-sectional, observational study, 370 eyes in 223 patients with PANDO were assessed. The ocular surface disease index (OSDI) was used to evaluate ocular surface symptoms, and the Keratograph 5M non-invasive ocular surface analyser was used to assess ocular surface parameters. According to the TFOS DEWS II criteria, patients with OSDI ≥ 13 and NIKBUT < 10s were diagnosed with DE. Of the 223 PANDO patients, 65 (29.1%) met the diagnostic criteria for DE. Compared with patients without DE, PANDO patients with DE were significantly older (p < 0.001), had a longer duration of epiphora (p = 0.023), and more likely to have a positive regurgitation on pressure over the lacrimal sac (ROPLAS) sign (p = 0.003). Multifactorial analysis showed that older age, positive ROPLAS and hypertension were significant independent predictors of DE (p < 0.05). Among the 147 unilateral PANDO patients without DE, the TMH, NIKBUT-first, NIKBUT-average and bulbar erythema scores were significantly higher in the PANDO sides. This study illustrated the prevalence of DE in PANDO patients was 29.1% and DE is more likely to occur in those who are older, have hypertension and are positive for ROPLAS. In addition, in patients with unilateral nasolacrimal duct obstruction, a decrease in tear film stability was observed in the healthy eye.

Serum tumor marker and CT body composition scoring system predicts outcomes in colorectal cancer surgical patients.

To investigate the prognostic value of preoperative body composition and serum tumor markers (STM) in patients undergoing surgical treatment for colorectal cancer (CRC) and to establish the prognostic score for patients with CRC. This study enrolled 365 patients (training set 245, validation set 120) with CRC who underwent surgical resection. The predictive value of various body composition features and STM for determining CRC prognosis were compared. A novel index score based on the independent risk factors from Cox regression for CRC patients was established and evaluated for its usefulness. Multivariate Cox regression showed that low skeletal muscle radiodensity (SMD) (p = 0.020), low subcutaneous fat area (SFA) (p = 0.029), high carcinoembryonic antigen (CEA) (p = 0.008), and high alpha-fetoprotein (AFP) (p = 0.039) were all independent prognostic factors for poor overall survival (OS). The multifactorial analysis indicated that high intermuscular fat area (IMFA) (p = 0.033) and high CEA (p = 0.009) were independent prognostic factors for poor disease-free survival (DFS). Based on these findings, two scoring systems for OS and DFS were established in the training datasets. CRC patients who scored higher on the new scoring systems had lower OS and DFS (both p < 0.001) as shown in the Kaplan-Meier survival curves in the training and validation datasets. In predicting the prognosis of CRC patients, SFA and SMD are superior to other body composition measurements. A scoring system based on body composition and STM can have prognostic value and clinical applicability. This scoring system, combining body composition and serum tumor markers, may help predict postoperative survival of CRC patients and help clinicians make well-informed decisions regarding the treatment of patients. Colorectal cancer prognosis can be related to body composition. High intermuscular fat area and CEA were independent prognostic factors for poor disease-free survival. This scoring system, based on body composition and tumor markers, can prognosticate for colorectal cancer patients.

Outcomes of heart transplantation in children with previously palliated hypoplastic left heart syndrome.

Paediatric heart transplantation in children who fail multistage palliation for hypoplastic left heart syndrome is associated with challenges related to immune, clinical or anatomic risk factors. We review current outcomes and risk factors for survival following heart transplantation in this challenging patient population. The United Network for Organ Sharing transplantation database was merged with Paediatric Health Information System database to identify children who received heart transplantation following prior palliation for hypoplastic left heart syndrome. Multivariable Cox analysis of outcomes and factors affecting survival was performed. Our cohort included 849 children between 2009 and 2021. The median age was 1044 days (interquartile range 108-3535), and the median weight was 13 kg (interquartile range 7-26). Overall survival at 10 years following heart transplantation was 71%, with most of the death being perioperative. On multivariable analysis, risk factors for survival included Black race (hazard ratio = 1.630, P = 0.0253), blood type other than B (hazard ratio = 2.564, P = 0.0052) and male donor gender (hazard ratio = 1.367, P = 0.0483). Recipient age, the use of ventricular assist device or extracorporeal membrane oxygenation were not significantly associated with survival. Twenty-four patients underwent retransplantation, and 10-year freedom from retransplantation was 98%. Rejection before hospital discharge and within 1 year from transplantation was 20% and 24%, respectively, with infants having lower rejection rates. Compared with existing literature, the number of children with prior hypoplastic left heart syndrome palliation who receive heart transplantation has increased in the current era. Survival following transplantation in this patient population is acceptable. Most of the death is perioperative. Efforts to properly support these patients before transplantation might decrease early mortality and improve overall survival.

Characteristics and distinct prognostic determinants of individuals with hepatosplenic T-cell lymphoma over the past two decades.

Hepatosplenic T-cell lymphoma (HSTCL) is a rare and aggressive peripheral T-cell lymphoma with historically dismal outcomes, representing less than one percent of non-Hodgkin lymphomas. Given its rarity, the true incidence of HSTCL is unknown and most data have been extrapolated through case reports. To the best of our knowledge, the largest and most up to date study addressing the epidemiology and outcomes of patients with HSTCL in the United States covered a period from 1996 to 2014, with a sample size of 122 patients. To paint the most updated epidemiological picture of HSTCL. A total of 186 patients diagnosed with HSTCL, between 2000 and 2017, were ultimately enrolled in our study by retrieving data from the Surveillance, Epidemiology, and End Results database. We analyzed demographics, clinical characteristics, and overall mortality (OM) as well as cancer-specific mortality (CSM) of HSTCL. Variables with a P value < 0.01 in the univariate Cox regression were incorporated into the multivariate Cox model to determine the independent prognostic factors, with a hazard ratio of greater than 1 representing adverse prognostic factors. Male gender was the most represented. HSTCL was most common in middle-aged patients (40-59) and less common in the elderly (80+). Non-Hispanic whites (60.75%) and non-Hispanic blacks (20.97%) were the most represented racial groups. Univariate Cox proportional hazard regression analysis of factors influencing all-cause mortality showed a higher OM among non-Hispanic black patients. CSM was also higher among non-Hispanic blacks and patients with distant metastasis. Multivariate Cox proportional hazard regression analysis of factors affecting CSM revealed higher mortality in patients aged 80 or older and non-Hispanic blacks. Overall, the outlook for this rare malignancy is very grim. In this retrospective cohort study of the United States population, non-Hispanic blacks and the elderly had a higher CSM. This data highlights the need for larger prospective studies to investigate factors associated with worse prognosis in one ethnic group, such as treatment delays, which have been shown to increase mortality in this racial/ethnic group for other cancers.

Association between Albumin-Corrected Anion Gap and Mortality in Patients with Cardiogenic Shock.

Cardiogenic shock (CS) is a critical illness with a high mortality rate in clinical practice. Although some biomarkers have been found to be associated with mortality in patients suffering from CS in previous studies. The albumin-corrected anion gap (ACAG) has not been studied in depth. Our study aimed to explore the relationship between ACAG and mortality in patients with CS. All baseline data was extracted from Medical Information Mart for Intensive Care-IV version: 2.0 (MIMIC-IV). According to the prognosis at 30 days of follow-up, they were divided into survivors and non-survivors groups. The survival curves between the two groups were drawn using the Kaplan-Meier method and the log-rank test. Valid factors were selected using the least absolute shrinkage and selection operator (LASSO) logistic analysis model. Analysis was performed to investigate the relationship between mortality and all enrolled patients using restricted cubic spline (RCS) and Cox proportional hazards models. Receiver operating characteristic (ROC) curves were used to assess the predictive ability of ACAG. Evaluation of final result stability using sensitivity analysis. 839 cases were selected to meet the inclusion criteria and categorized into survivors and non-survivors groups in the final analysis. The ACAG value measured for the first time at the time of admission was selected as the research object. Kaplan-Meier (K-M) survival curves showed that cumulative 30- and 90-day survival decreased progressively with elevated ACAG (p 0.001), and multifactorial Cox regression analyses showed ACAG to be an independent risk factor for increased 30- and 90-day mortality in patients suffering from CS (p 0.05). RCS curves revealed that all-cause mortality in this group of patients increased with increasing ACAG ( 2 = 5.830, p = 0.120). The ROC curve showed that the best cutoff value for ACAG for predicting 30-day mortality in patients with CS was 22.625, with a sensitivity of 44.0% and a specificity of 74.7%. The relationship between ACAG and CS short-term mortality remained stable in all sensitivity analyses (All p 0.05). The ACAG is an independent risk factor for 30- and 90-day mortality in CS patients and predicts poor clinical outcomes in CS patients. According to our study, elevated ACAG at admission, especially when ACAG 20 mmol/L, was an independent predictor of all-cause mortality in CS.

Predictive efficacy of the preoperative neutrophil–lymphocyte ratio in lymph node metastasis of cN0 hormone receptor-positive breast cancer

Breast cancer, as the most common cancer, has surpassed lung cancer worldwide. The neutrophil-to-lymphocyte ratio (NLR) has been linked to the onset of cancer and its prognosis in recent studies. However, quite a few studies have shown that there is a link between NLR and lymph node metastases in cN0 hormone receptor-positive (HR(+)) breast cancer. The purpose of this study was to evaluate the correlation between NLR and lymph node metastases in cN0 HR(+) breast cancer patients. From January 2012 to January 2022, 220 patients with cN0 HR(+) invasive breast cancers were enrolled in this study. The relationship between NLR and pathological data was statistically examined. The receiver operating characteristic (ROC) curve was used to determine the optimal cutoff of NLR, a chi-squared test was used for the univariate analysis, and logistic analysis was used for the multivariate analysis. The NLR had an optimal cutoff of 2.4 when the Jorden index was at a maximum. Patients with axillary lymph node metastases had a higher NLR (P < 0.05). A Univariate analysis showed that there were significant differences in cN0 HR(+) breast cancer with axillary lymph node metastasis among different clinical stages, histological grades, Ki-67 levels, tumor sizes, and NLR levels (P < 0.05). Clinical stage, tumor size, and NLR were found to be independent risk factors for lymph node metastases in multifactorial analysis. In cN0 HR(+) breast cancer, NLR is an independent risk factor for lymph node metastases. An NLR ≥ 2.4 indicates an increased probability of lymph node metastases. An elevated preoperative NLR has a high predictive value for axillary lymph node metastases.

Multi-factor thermal analysis of phase change material integrated roofing elements

In the present study, the PCM layer is integrated into the roof, analyzed, and compared for its thermal behaviour in terms of Indoor Air Temperature Reduction (IATR), Thermal Load Levelling (TLL), and Lag Time (LT) to determine the ideal position, thickness, and type of PCM. The observations from the experimental analysis were validated using COMSOL Multiphysics v6.0 with available literature. The results showed that PCM-integrated roofs reduced the interior temperature by around 30%. Furthermore, the fluctuations in the interior temperatures were reduced to 6.1% with PCM integration within the roof. A lag time of 5–8.25 h was observed for the PCM roofs. The study also found that the material properties impact the overall thermal behaviour of the PCM-integrated roofs. These properties were further explored using continuous cyclic thermal loading and variation of latent heat over a period of four days for three climatic zones in India. Abbreviations: PCM: Phase Change Material; CC: Conventional Concrete; AAC: Autoclaved Aerated Cement; TMY: Typical Meteorological Years; epw file: Energy Plus Weather File; mPCM: Microencapsulated Phase Change Material; PTC: Positive Temperature Coefficient; DHT: Digital Temperature And Humidity; IATR: Indoor Air Temperature Reduction (%); TLL: Thermal Load Levelling (%); LT: Lag Time (hours)

Objective: To understand the health-related quality of life for patients of pneumoconiosis combined with tuberculosis and its main influencing factors. Methods: This was a cross-sectional study, and 951 patients of pneumoconiosis combined with tuberculosis from the pneumoconiosis survey in 27 provinces and autonomous regions in China from December 2017 to December 2021 were selected for the study. The nonparametric Mann-Whitney test and the Kruskal-Wallis H test were used to compare the health utility values, and multiple linear regression was used for multifactor analysis. AMOS 24.0 was used to establish a structural equation modeling. Results: The mean age of 951 patients of pneumoconiosis combined with tuberculosis was (59.3±12.4) years. The main types were silicosis combined with tuberculosis (62.2%, 591/951) and coal-worker's pneumoconiosis combined with tuberculosis (34.9%, 332/951), and other type pneumoconiosis-combined tuberculosis was 2.9% (28/951). The proportion of patients with stage Ⅰ, Ⅱ, Ⅲ, and unstaged clinical diagnosis was 27.4% (261/951), 26.6% (253/951), 32.5% (309/951) and 13.5% (128/951), respectively. 63.3% (602/951) of study participants suffered from other chronic diseases, and the percentage of patients combined the number of chronic diseases with 1, 2, and more than 3 respectively were 24.1% (229/951), 16.3% (155/951) and 22.9% (218/951). The median and quartiles of health utility values and the mean±standard deviation of self-rating scores of patients of pneumoconiosis combined with tuberculosis were 0.562 (0.482, 0.766) and (53.7±18.4), respectively, which were lower than patients of pneumoconiosis without tuberculosis (Z=-11.29, P<0.001; t=8.97, P<0.01). The health utility values and self-rating scores for patients of pneumoconiosis combined with tuberculosis were significantly different between urban and rural areas (Z= -2.22, P=0.027; t=4.85, P<0.01). Pain/discomfort was the most frequently reported problem in the five-dimensional distribution of problems, followed by daily activities and anxiety/depression, and the difference in the percentage reported by anxiety/depression between urban and rural areas was significant (χ(2)=30.28, P<0.01). The results of multiple linear regression showed that the survey area, body mass index, education level, age, employment status, annual personal income, stage of pneumoconiosis, number of multi-morbidities, hemoptysis, acute exacerbation of symptoms in two-week, social support and minimum living standard were the main influences on the health utility values of the patients of pneumoconiosis combined with tuberculosis (P<0.05). The results of structural equation model showed that economic security and health status directly affected the health-related quality of life among patients of pneumoconiosis combined with tuberculosis and played a chain-mediating effect in the influence of socioeconomic status on the health-related quality of life among patients of pneumoconiosis combined with tuberculosis. Conclusion: Health-related quality of life was poorer in patients of pneumoconiosis with tuberculosis, with pain and discomfort and anxiety/depression problems being more pronounced, and economic status and health status played multiple mediating roles in the influence of general socio-demographic characteristics on quality of life in pneumoconiosis.

Multifactor Analyses of Frontal Cortex Lipids in the APP/PS1 Model of Familial Alzheimer's Disease Reveal Anomalies in Responses to Dietary n-3 PUFA and Estrogenic Treatments.

Brain lipid homeostasis is an absolute requirement for proper functionality of nerve cells and neurological performance. Current evidence demonstrates that lipid alterations are linked to neurodegenerative diseases, especially Alzheimer's disease (AD). The complexity of the brain lipidome and its metabolic regulation has hampered the identification of critical processes associated with the onset and progression of AD. While most experimental studies have focused on the effects of known factors on the development of pathological hallmarks in AD, e.g., amyloid deposition, tau protein and neurofibrillary tangles, neuroinflammation, etc., studies addressing the causative effects of lipid alterations remain largely unexplored. In the present study, we have used a multifactor approach combining diets containing different amounts of polyunsaturated fatty acids (PUFAs), estrogen availabilities, and genetic backgrounds, i.e., wild type (WT) and APP/PS1 (FAD), to analyze the lipid phenotype of the frontal cortex in middle-aged female mice. First, we observed that severe n-3 PUFA deficiency impacts the brain n-3 long-chain PUFA (LCPUFA) composition, yet it was notably mitigated by hepatic de novo synthesis. n-6 LCPUFAs, ether-linked fatty acids, and saturates were also changed by the dietary condition, but the extent of changes was dependent on the genetic background and hormonal condition. Likewise, brain cortex phospholipids were mostly modified by the genotype (FAD>WT) with nuanced effects from dietary treatment. Cholesterol (but not sterol esters) was modified by the genotype (WT>FAD) and dietary condition (higher in DHA-free conditions, especially in WT mice). However, the effects of estrogen treatment were mostly observed in relation to phospholipid remodeling in a genotype-dependent manner. Analyses of lipid-derived variables indicate that nerve cell membrane biophysics were significantly affected by the three factors, with lower membrane microviscosity (higher fluidity) values obtained for FAD animals. In conclusion, our multifactor analyses revealed that the genotype, diet, and estrogen status modulate the lipid phenotype of the frontal cortex, both as independent factors and through their interactions. Altogether, the outcomes point to potential strategies based on dietary and hormonal interventions aimed at stabilizing the brain cortex lipid composition in Alzheimer's disease neuropathology.
