Predictive Value of Multiple Scoring Systems in the Prognosis of Septic Patients with Different Infection Sites: Analysis of the Medical Information Mart for the Intensive Care IV Database.

The heterogeneity nature of sepsis is significantly impacted by the site of infection. This study aims to explore the predictive value of multiple scoring systems in assessing the prognosis of septic patients across different infection sites. Data for this retrospective cohort study were extracted from the Medical Information Mart for Intensive Care IV database (MIMIC-IV) (v2.2). Adult patients meeting the criteria for sepsis 3.0 and admitted to the intensive care unit (ICU) were enrolled. Infection sites included were pneumonia, urinary tract infection (UTI), cellulitis, abdominal infection, and bacteremia. The primary outcome assessed was 28-day mortality. The sequential Organ Failure Assessment (SOFA) score, Oxford Acute Severity of Illness Score (OASIS), and Logistic Organ Dysfunction System (LODS) score were compared. Binomial logistic regression analysis was conducted to evaluate the association between these variables and mortality. Additionally, differences in the area under the curve (AUC) of receiver operating characteristic (ROC) among the scoring systems were analyzed. A total of 4721 patients were included in the analysis. The average 28-day mortality rate was 9.4%. Significant differences were observed in LODS, OASIS, and SOFA scores between the 28-day survival and non-survival groups across different infection sites (p < 0.01). In the pneumonia group and abdominal infection group, both the LODS and OASIS scoring systems emerged as independent risk factors for mortality in septic patients (odds ratio [OR]: 1.165, 95% confidence interval [CI]: 1.109-1.224, p < 0.001; OR: 1.047, 95% CI: 1.028-1.065, p < 0.001) (OR: 1.200, 95% CI: 1.091-1.319, p < 0.001; OR: 1.060, 95% CI: 1.025-1.095, p < 0.001). For patients with UTI, the LODS, OASIS, and SOFA scoring systems were identified as independent risk factors for mortality (OR: 1.142, 95% CI: 1.068-1.220, p < 0.001; OR: 1.062, 95% CI: 1.037-1.087, p < 0.001; OR: 1.146, 95% CI: 1.046-1.255, p = 0.004), with the AUC of LODS score and OASIS significantly higher than that of the SOFA score (p = 0.006). Among patients with cellulitis, the OASIS and SOFA scoring systems were identified as independent risk factors for mortality (OR: 1.055, 95% CI: 1.007-1.106, p = 0.025; OR: 1.187, 95% CI: 1.005-1.403, p = 0.044), with no significant difference in prognosis prediction observed (p = 0.243). In the bacteremia group, the LODS scoring system was identified as an independent risk factor for mortality (OR: 1.165, 95% CI: 1.109-1.224, p < 0.001). The findings suggest that LODS scores offer better prognostic accuracy for predicting the mortality risk in septic patients with pneumonia, abdominal infections, bacteremia, and UTI compared to SOFA scores.

The association of cholesterol crystals and non-culprit plaque characteristics in AMI patients: an OCT study

Objective: To analyze plaque characteristics of non-culprit coronary lesions with cholesterol crystals in patients with acute myocardial infarction(AMI) by using optical coherence tomography(OCT). We also investigated the potential association between cholesterol crystals with plaque rupture and healed plaque at non-culprit segment. Methods: This study was a retrospective cohort study. Between January 2017 and December 2017, patients with AMI who underwent 3-vessel OCT imaging were included in this study. Patients were divided into two groups according to the presence or absence of cholesterol crystals at the non-culprit lesions. All patients underwent coronary angiography and OCT examination, and non-culprit plaque characteristics were compared between the two groups. The generalized estimating equation log-binomial multirariate regression model was used to assess the relationship between non-culprit lesions with cholesterol crystals and plaque rupture and plaque healing. The follow-up data collection ended in October 2023. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the cumulative incidence of major adverse cardiovascular events between the two groups. Results: A total of 173 AMI patients were included (aged (56.8±11.6) years; 124 men (71.7%)). Among 710 non-culprit lesions identified by OCT, there were 102 (14.4%) in cholesterol crystals group and 608 (85.6%) in non-cholesterol crystals group. Compared with non-culprit lesions without cholesterol crystals, those with cholesterol crystals had smaller minimum lumen diameter, severer diameter stenosis, and longer lesion length (all P<0.01). The prevalence of plaque rupture (17.6% (18/102) vs. 4.9% (30/608), P=0.001) and thin-cap fibroatheroma (31.4% (32/102) vs. 11.5% (70/608), P<0.01) was higher in the cholesterol crystals groups than in the non-cholesterol crystals group. In addition, vulnerable plaque characteristics such as (44.1% (45/102) vs. 25.8% (157/608), P<0.01), macrophages were more frequently observed in non-culprit lesions with cholesterol crystals. The generalized estimating equation log-binomial multivariate regression analyses showed that non-culprit cholesterol crystals were positively correlated with healed plaque (OR=1.583, 95%CI: 1.004-2.495, P=0.048). Conversely, cholesterol crystals were not associated with plaque rupture (OR=1.632, 95%CI: 0.745-3.576, P=0.221). The follow-up time was 2 142 (1 880, 2 198) days. Non-culprit cholesterol crystals were not related to the major adverse cardiovascular events in patients with AMI (log-rank P=0.558). Conclusions: Among AMI patients, non-culprit lesions with cholesterol crystals presented with severer luminal stenosis and increased plaque vulnerability. The presence of non-culprit cholesterol crystals was associated with rather than plaque rupture.

Hysterectomy—a possible risk factor for operative intervention in female patients for degenerative lumbar spine conditions: a case control and cohort study

Researchers have recently linked hysterectomy, which alters sex hormone levels, to diseases like osteoporosis, lumbar spondylolisthesis, hypertension and diabetes etc. However, the association between hysterectomy and lumbar disc herniation (LDH)/lumbar spinal stenosis (LSS) remains unclarified. To determine whether there is a correlation between hysterectomy and surgical intervention for LDH/LSS in women, further substantiated through imaging and clinical research. A case control and cohort study. The study group comprised 1202 female patients aged 45 and older who had undergone operative treatment due to LDH/LSS (825 for LDH and 377 for LSS), and the comparison group comprised 1168 females without lumbar diseases who visited health examination clinic during the same period. One hundred and 2 hysterectomized patients were further selected (Hysterectomy cohort) and matched approximately with the control cohort at a 1:2 ratio from the study group with a minimum follow-up of 2 years. Odds Ratios (ORs) and 95% Confidence Intervals (CIs) were calculated to assess the association between hysterectomy and surgical intervention for LDH/LSS in women after adjusted by confounding factors. Patients from both the hysterectomy and control cohorts underwent a comprehensive assessment. This assessment included the evaluation of several parameters: the functional cross-sectional area, fat infiltration rate, relative functional cross-sectional area of the lumbar paravertebral muscles, facet joint degeneration grade, cartilage endplate damage, Modic changes for the L3/4-L5/S1 segments, Pfirrmann grade of lumbar disc degeneration, and disc height index for the L1/2-L5/S1 segments. Additionally, the Visual Analog Scale (VAS) and Japanese Orthopaedic Association (JOA) scores were recorded preoperatively and at the last follow-up. Associations between hysterectomy and patients treated surgically for LDH or LSS were analyzed using multivariate binomial logistic regression analysis. Lumbar X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) were used to evaluate the imaging variables. Imaging and clinical variables were compared. Hysterectomized women were associated with requiring surgery due to LDH/LSS, with ORs of 2.613 (p<.001) and 2.084 (p=.006), respectively. The imaging evaluation further revealed that the hysterectomy cohort had more severe degeneration of the paraspinal muscles, facet joints, endplates, and intervertebral discs, Modic changes at L3/4-L5/S1 segments, and intervertebral height reduction at L1/2-L5/S1 segments when compared to the control cohort (p<.01). Compared to the control cohort, the hysterectomy cohort exhibited higher preoperative and last follow-up VAS scores for low back pain, and last follow-up JOA scores (p<.01). Based on the findings of this study, it seems that women who have had a hysterectomy are correlated with requiring surgical intervention due to LDH/LSS. Imaging and clinical studies also indicate that hysterectomized patients exhibited more severe lumbar degeneration and back pain.

Risk of acute kidney injury following contrast-enhanced CT or MRI in a cohort of 3061 hospitalized children in China

ObjectivesTo compare the risk of acute kidney injury (AKI) between hospitalized children who received intravenous contrast media for imaging examinations and those who did not.MethodsThis retrospective cohort study enrolled patients aged 0–18 years with serum creatinine levels before and after imaging examinations from 2015 to 2020 at Beijing Children’s Hospital. Participants were classified into an exposure group or a control group. Log-binomial regression analysis was used to estimate the adjusted risk ratio (aRR) value for the association between exposure to contrast media and consequential AKI. After which, inverse probability treatment weighting was used to reduce systematic differences in baseline characteristics among the groups. Moreover, subgroup and sensitivity analyses were performed. Finally, multivariate logistic regression analysis was performed to identify risk factors for pediatric AKI.ResultsIn total, 3061 pediatric patients were included in the analyses (median age, 4.5 [IQR, 1.3–8.9] years, 1760 males). According the KDIGO definition of AKI, the incidence of AKI in the exposure group, and the control group were 7.4% and 6.5%, respectively; furthermore, the aRR was 1.35 (95% CI: 1.31–1.39). In patients underwent CT, the risk of AKI in the exposure group of contrast media increased compared with the control group and the aRR was 1.39 (95% CI: 1.09–1.78). However, it is not observed in patients underwent MRI (aRR: 1.36; 95% CI: 0.96–1.95). According to our subgroup analysis of pediatric patients aged ≥ 2 years (aRR: 1.38; 95% CI: 1.05–1.82) and sensitivity analysis (aRR: 1.32, 95% CI: 1.08–1.61), the risk of AKI in the exposure group was greater than that in the control group. An increased risk to exposure to contrast media was seen in females (aRR: 1.41, 95% CI: 1.05–1.89) rather than males (aRR: 1.30, 95% CI: 0.99–1.70). According to the multivariate logistic regression analyses, the baseline eGFR (OR: 1.02; 95% CI: 1.01–1.03) and comorbidities (OR: 2.97; 95% CI: 1.89–4.65) were risk factors, while age (OR: 0.87; 95% CI: 0.84–0.91) was a protective factor against AKI.ConclusionThe evidence from the present study suggested that the increased risk of AKI in hospitalized children induced by intravascular contrast should not be ignored.

Systemic immune-inflammation index mediates the association between metabolic dysfunction-associated fatty liver disease and sub-clinical carotid atherosclerosis: a mediation analysis.

Limited research has been conducted to quantitatively assess the impact of systemic inflammation in metabolic dysfunction-associated fatty liver disease (MAFLD) and sub-clinical carotid atherosclerosis (SCAS). The systemic immune-inflammation index (SII), which integrates inflammatory cells, has emerged as a reliable measure of local immune response and systemic inflammation Therefore, this study aims to assess the mediating role of SII in the association between MAFLD and SCAS in type 2 diabetes mellitus (T2DM). This study prospectively recruited 830 participants with T2DM from two centers. Unenhanced abdominal CT scans were conducted to evaluate MAFLD, while B-mode carotid ultrasonography was performed to assess SCAS. Weighted binomial logistic regression analysis and restricted cubic splines (RCS) analyses were employed to analyze the association between the SII and the risk of MAFLD and SCAS. Mediation analysis was further carried out to explore the potential mediating effect of the SII on the association between MAFLD and SCAS. The prevalence of both MAFLD and SCAS significantly increased as the SII quartiles increased (P<0.05). MAFLD emerged as an independent factor for SCAS risk across three adjusted models, exhibiting odds ratios of 2.15 (95%CI: 1.31-3.53, P < 0.001). Additionally, increased SII quartiles and Ln (SII) displayed positive associations with the risk of MAFLD and SCAS (P < 0.05). Furthermore, a significant dose-response relationship was observed (P for trend <0.001). The RCS analyses revealed a linear correlation of Ln (SII) with SCAS and MAFLD risk (P for nonlinearity<0.05). Importantly, SII and ln (SII) acted as the mediators in the association between MAFLD and SCAS following adjustments for shared risk factors, demonstrating a proportion-mediated effect of 7.8% and 10.9%. SII was independently correlated with MAFLD and SCAS risk, while also acting as a mediator in the relationship between MAFLD and SCAS.

University Students' Vaccination Intention after the Fifth Wave of the COVID-19 Outbreak in Hong Kong: Inspiration from a Health Belief Model.

The fifth wave of COVID-19, driven by the Omicron variant, started to surge in Hong Kong in December 2021. Previous studies have shown that younger adults, compared to older adults, are vulnerable to increased risks of side effects after vaccination. However, little is known about the COVID-19 vaccination behavior among younger adults, especially university students, in Hong Kong. Therefore, the present online survey study aimed to investigate the predictors of COVID-19 vaccination intention among university students in Hong Kong using the Health Belief Model (HBM) as a framework. Two other potential predictors, the previous influenza vaccine uptake frequency and the Hong Kong SAR government vaccination lottery program, were also examined. The intention to receive another dose of the COVID-19 vaccine was low (36.4%). Multivariate binomial logistic regression analysis showed that, after controlling for demographic and baseline characteristics, the perceived susceptibility (OR = 2.98, CI = 1.18-7.53) and previous influenza vaccine uptake frequency (OR = 1.54, CI = 1.08-2.19) significantly and positively predicted the COVID-19 vaccination intention. However, the government vaccination lottery program (i.e., wining prizes for being vaccinated) (OR = 0.87, CI = 0.34-2.26) was not a significant motivator of COVID-19 vaccination. Future public health campaigns should focus on the individual susceptibility to COVID-19 and past influenza vaccination history to promote increased vaccination uptake among university students.

Police-referred psychiatric emergency presentations during the first and second wave of COVID-19 in Berlin, Germany: a retrospective chart review

BackgroundLiterature on psychiatric emergency services (PES) presentations during the COVID-19 pandemic showed heterogeneous results regarding patients brought in by police (BIBP). This is the first study primarily focusing on patients BIBP in a PES during the COVID-19-period.MethodsCase documentation records during the first and second wave of the COVID-19 pandemic in a PES in Berlin, Germany were analyzed using descriptive data analysis and binomial logistic regression analysis to detect factors that predict presentations BIBP.Results5440 PES presentations: 20.4% BIBP during the first wave vs. 16.3% during its control period; second wave: 17.6% BIBP vs. 14.9% during its control period. In both waves, absolute increases in presentations BIBP were seen compared to control (p = .029, p = .028, respectively). COVID-19-period was a predictor for presentations BIBP during the first and the second wave. The following factors also predicted presentations BIBP: younger age, male gender, aggressive behavior, suicide attempt prior to presentation and diagnosis of psychotic or substance use disorders; depressive disorders were negatively associated.ConclusionsDuring the two first waves of the COVID-19 pandemic, there was an increase in presentations BIBP in a PES in Berlin. Regression analysis shows that the pandemic itself was a predictor of presentations BIBP. The underlying factors of this association need to be further elucidated in future research. Additionally, general factors predicting PES presentations BIBP are reported that replenish the present literature.

Easing anxiety symptoms through leisure activities during social isolation: Findings from nationally representative samples.

Public health interventions implemented during the COVID-19 pandemic may exacerbate anxiety symptoms for many. We conducted this study to better understand the role of leisure activity in promoting mental wellness during times of social isolation and reduced access to recreation facilities and mental health support services. We analyzed nationally representative survey data collected by Statistics Canada as part of the Canadian Perspectives Survey Series (CPSS) during May 4-10 (CPSS 2) and July 20 to 26, 2020 (CPSS 4). Data related to leisure activity and anxiety symptoms as measured by a score of more than 10 on the General Anxiety Disorder scale were examined using descriptive and log-binomial regression analyses. Survey sampling weights were applied in all analyses, and regression results were adjusted for sociodemographic characteristics. Exercise and communication with friends and loved ones were the most frequently reported leisure activity. Prevalence of moderate to severe anxiety symptoms reported by participants was lower in CPSS 4 compared to CPSS 2. Results of adjusted log-binomial regression analyses revealed lower prevalence of moderate to severe anxiety symptoms in those who engaged in exercise and communication, while those who meditated exhibited higher prevalence. In conclusion, leisure activities, such as exercise and communication with loved ones, can promote mental wellness. Future research should clarify the role of meditation for mental wellness promotion during periods of social isolation.

Diagnostic Sensitivity and Symptomatic Relevance of Dopamine Transporter Imaging and Myocardial Sympathetic Scintigraphy in Patients with Dementia with Lewy Bodies.

Dementia with Lewy bodies (DLB) presents with various symptoms, posing challenges for early diagnosis challenging. Dopamine transporter (123I-FP-CIT) single-photon emission tomography (SPECT) and 123I-meta-iodobenzylguanidine (123I-MIBG) imaging are crucial diagnostic biomarkers. Hypothesis about body- and brain-first subtypes of DLB indicate that some DLB may show normal 123I-FP-CIT or 123I-MIBG results; but the characteristic expression of these two subtypes remains unclear. This study aimed to evaluate the diagnostic sensitivity of 123I-FP-CIT and 123I-MIBG imaging alone, combined in patients with DLB and explore symptoms associated with the abnormal imaging results. Demographic data, clinical status, and imaging results were retrospectively collected from patients diagnosed with possible DLB. Both images were quantified using semi-automated software, and the sensitivity of each imaging modality and their combination was calculated. Demographic data, cognition, and motor and non-motor symptoms were compared among the subgroups based on the imaging results. Symptoms related to each imaging abnormality were examined using binomial logistic regression analyses. Among 114 patients with DLB, 80 underwent 123I-FP-CIT SPECT (sensitivity: 80.3%), 83 underwent 123I-MIBG imaging (68.2%), and 66 both (sensitivity of either abnormal result: 93.9%). Visual hallucinations differed among the four subgroups based on imaging results. Additionally, nocturia and orthostatic hypotension differed between abnormal and normal 123I-MIBG images. Overall, 123I-FP-CIT SPECT was slightly higher sensitivity than 123I-MIBG imaging, with combined imaging increasing diagnostic sensitivity. Normal results of a single imaging test may not refute DLB. Autonomic symptoms may lead to abnormal 123I-MIBG scintigraphy findings indicating body-first subtype of patients with DLB.

The relationships of inflammatory blood markers with maternal periodontal and dental states and their effects on preterm membrane rupture development

BackgroundThe influence of maternal oral and dental health on the occurrence of Preterm Premature Rupture of Membranes (P-PROM) and its underlying mechanisms remain uncertain. This research seeks to investigate the impact of maternal oral and dental health on the incidence of P-PROM and its association with inflammatory markers in the blood.MethodsThis study adopts a prospective case-control design methodology. The study involved 70 women diagnosed with P-PROM and delivered by an obstetrician and 79 women who had healthy deliveries with no prenatal complications. The values for DMFT (Number of decayed, missing and filled teeth) index, Gingival Index (GI), Plaque index (PI), Pocket depth (PD), Clinical attachment loss (CAL) and medical history were recorded. Mann-Whitney U test and hierarchical binomial logistic regression analysis were applied. It was considered statistically significant at p < 0.05.ResultsThe case group’s DMFT, PI, GI, PD values were statistically significantly higher than the control group (p < 0.001). There was no relationship between DMFT, GI, PD, CAL and inflammatory blood markers (p > 0.05). In the regression analysis for possible risk factors that may be effective in P-PROM, oral and dental health parameters were the most effective.ConclusionsOral and dental health of women with P-PROM was found to be worse than that of the control group. Oral and dental health may be a potential risk factor that may contribute to adverse pregnancy outcomes associated with P-PROM.

Association between Internet Use and Locomotive Syndrome, Frailty, and Sarcopenia among Community-Dwelling Older Japanese Adults.

In the lives of those who are the target of community health nursing, it is important to collaborate with individuals and communities to improve their quality of life. Herein, we aimed to determine the association between Internet use among older individuals and locomotive syndrome (LS), frailty, and sarcopenia. In this cross-sectional study conducted between July 2022 and March 2023, we recruited 105 community-dwelling older Japanese adults who participated in a care prevention project called "Kayoi-no-ba". All participants were divided into Internet and non-Internet user groups according to the classification of a previous study. We assessed LS (standing test, two-step test, and five-question Geriatric Locomotive Function Scale), frailty (through the Questionnaire for Medical Checkup of Old-Old), and sarcopenia (grip strength, normal walking speed, and skeletal muscle mass index) and made group comparisons between Internet users and non-users. Binomial logistic regression analyses were performed with Internet use as the independent variable and sarcopenia or LS as the dependent variables. The Internet and non-Internet user groups had 69 and 36 participants, respectively. The Internet user group comprised 65.7% of all participants, which was similar to that reported in a previous study of the same age group. Between-group comparisons showed significant differences in sarcopenia and LS items, whereas adjusted binomial logistic analysis showed a significant association between sarcopenia and Internet use. In summary, among LS, frailty, and sarcopenia, sarcopenia showed the highest association with Internet use. Older adults without sarcopenia having good physical functions, such as grip strength, walking speed, and skeletal muscle index, more likely used the Internet; while older adults with sarcopenia were less likely to use the Internet. This implied that Internet use may be associated with physical function.

Does supplemental private health insurance impact health care utilization and seeking behavior of residents covered by social health insurance? Evidence from China National Health Services Survey

BackgroundSupplemental private health insurance (PHI) plays a crucial role in complementing China’s social health insurance (SHI). However, the effectiveness of incorporating PHI as supplementary coverage lacks conclusive evidence regarding its impact on healthcare utilization and seeking behavior among SHI-covered individuals. Therefore, investigating the effects of supplementary PHI on health care utilization and seeking behavior of residents covered by social health insurance is essential to provide empirical evidence for informed decision-making within the Chinese healthcare system.MethodsData from the 2018 China National Health Services Survey were analyzed to compare outpatient and inpatient healthcare utilization and choices between PHI purchasers and non-purchasers across three SHI schemes: urban employee-based basic medical insurance (UEBMI), urban resident-based basic medical insurance (URBMI), and the new rural cooperative medical scheme (NRCMS). Using the Andersen Healthcare Services Utilization Behavior Model as the theoretical framework,binary logistic regression and multinomial logistic regression (MNL) models were employed to assess the impact of PHI on healthcare utilization and provider preferences.ResultsAmong UEBMI, URBMI, and NRCMS participants with PHI, outpatient visit rates were 17.9, 19.8, and 21.7%, and inpatient admission rates were 12.4, 9.9, and 12.9%, respectively. Participants without PHI exhibited higher rates for outpatient visits (23.6, 24.3, and 25.6%) and inpatient admissions (15.2, 12.8, and 14.5%). Binomial logistic regression analyses revealed a higher probability of outpatient visits and inpatient admissions among UEBMI participants with PHI (p < 0.05). NRCMS participants with PHI showed a lower probability of outpatient visits but a higher probability of inpatient admissions (p < 0.05). Multinomial logistic regression indicated that NRCMS participants with PHI were more likely to choose higher-level hospitals, with a 17% increase for county hospitals and 27% for provincial or higher-level hospitals compared to primary care facilities.ConclusionThe findings indicate that the possession of PHI correlated with increased utilization of outpatient and inpatient healthcare services among participants covered by UEBMI. Moreover, for participants under the NRCMS, the presence of PHI is linked to a proclivity for seeking outpatient care at higher-level hospitals and heightened utilization of inpatient services. These results underscore the nuanced influence of supplementary PHI on healthcare-seeking behavior, emphasizing variations across individuals covered by distinct SHI schemes.

Consecutive positive nucleic acid tests in COVID-19 patients: a retrospective cohort study in Fangcang hospitals, Shanghai.

The coronavirus disease 2019 (COVID-19) spread rapidly in Shanghai in February 2022. Patients with asymptomatic and mild symptoms were admitted to Fangcang shelter hospitals for centralized quarantine. A total of 5,217 non-severe patients hospitalized in the Longyao Fangcang and Shilong Fangcang hospitals were included in the study. Demographic and clinical characteristics, comorbidity, exposure history, treatment and disease duration were analyzed. Univariate analysis and binomial logistic regression analysis were performed to identify the factors influencing nucleic acid change from positive to negative over 14 days. Consecutive positive nucleic acid test results (days) were significantly associated with advanced age (OR = 1.343, 95% CI 1.143 to 1.578, p < 0.001), smoking (OR = 0.510, 95% CI 0.327 to 0.796, p = 0.003) and vaccination (OR = 0.728, 95% CI 0.641 to 0.827, p < 0.001). However, there was no significant difference between asymptomatic and mild symptomatic patients (p = 0.187). In univariate analysis, comorbidities including diabetes, hypertension, cardiovascular system, malignant tumors, autoimmune diseases and cerebral apoplexy were associated with consecutive positive nucleic acid test results, but there was no significant difference in binomial logistics regression analysis. Aging and comorbid conditions lead to the prolongation of positive nucleic acid test results for several days. Improving vaccination coverage is beneficial for prevention and control of the epidemic. The management and treatment methods of Shanghai Fangcang shelter hospitals had important referential significance, which can provide valuable guidance for the prevention and control of the COVID-19 epidemic in the future.

An empirical analysis of the effects of nudge-based measures on job seekers' participatory behavior in the Care Worker Initial Training

Objectives The study aim was to explore effective measures to promote job seekers' participation in the Care Worker Initial Training course provided by Hello Work.Methods In this study, we adopted the nudge approach as a method to promote behavioral changes based on a knowledge of behavioral economics. Additionally, we tested the effectiveness of nudge-based measures compared to that of conventional measures. The survey was conducted through two rounds of Web distribution. In the first Web distribution, we consistently implemented the following, in order: 1) recruited individuals who agreed to participate in the study, 2) distributed the first Web questionnaire regarding basic attributes and eligibility criteria in terms of the target individuals, and 3) distributed course guidance. Individuals who responded to the first Web questionnaire (n=50,000) were randomly assigned to eight groups. The intervention groups were presented with course guidance based on loss-aversion nudge, empathy nudge, long-term gain nudge, and their combinations. The control group was presented with traditional course guidance used by the Ministry of Health, Labour and Welfare over the Web. Two weeks after the intervention, we identified 2,404 individuals who met the eligibility criteria and assessed their behavioral changes (pre-contemplation, contemplation/preparation, information-gathering, action); we received responses from 1,995 individuals. Binomial logistic regression analyses were performed using nudge-based interventions and behavioral change stages as dependent and independent variables, respectively. Sex, age, education level, marital status, interest in caregiving before the intervention, and behavioral change stages before the intervention were included as moderator variables.Results A total of 1,995 individuals were included in the analysis. Among the 1,756 participants in the intervention groups, 321 (18.3%) took on contemplation/preparation behavior, 102 (5.8%) took on information-gathering behavior, and 50 (2.8%) took action by participating in the course. Among the 239 individuals in the control group, 38 (15.9%) took on contemplation/preparation behavior, 31 (13.0%) took on information-gathering behavior, and 2 (0.8%) took action by participating in the course. Binomial logistic regression analyses showed that while traditional measures were effective in promoting information-gathering behavior toward participation, nudge-based measures combining loss-aversion nudge, long-term gain nudge, and empathy nudge were effective in motivating individuals to participate in the course (odds ratio: 5.39, 95%CI: 1.18-24.74, P=0.03).Conclusion The introduction of measures combining multiple types of nudges is necessary to promote participation in the Care Worker Initial Training course, rather than traditional measures or a nudge in isolation.

Factors Associated with Discharge Destination in Patients with Bone Metastases.

Background and Objectives: The discharge destination of patients with advanced cancer correlates with their quality of life. Patients with bone metastases often undergo lifestyle changes owing to pain and activity limitations. However, there are few reports on factors related to the discharge destination of patients with bone metastases. This study aimed to elucidate the factors associated with the discharge destination of patients with bone metastases. Methods: This study included 278 patients diagnosed with bone metastases who were admitted to the University of Tsukuba Hospital between April 2015 and March 2020. This study examined discharge destination, occurrence of skeletal-related events (SREs), primary lesions, locations of bone metastases, functional ambulation categories (FAC), age, and length of hospital stay. A binomial logistic regression analysis was conducted to compare the home and non-home discharge groups. Results: Of the 278 patients, 142 were discharged to home, 89 were discharged to somewhere other than home (non-home), and 47 died. The discharge destination was associated with spinal cord compression (SCC) (odds ratio [OR] 3.37, 95% confidence interval [CI] 1.35-8.43), hypercalcemia (OR 6.84, 95% CI 1.09-42.76), and FAC at admission (OR 0.45, 95% CI 0.35-0.58). The admission FAC cut-off value for discharge to home was determined to be 1.5 (area under the curve [AUC] 0.79, sensitivity 77.5%, specificity 68.5%). Conclusions: Factors associated with discharge destination were identified. The walking ability required for discharge to home was FAC 1.5, meaning that the patient needed one person to assist in preventing falls when walking on level ground. A cut-off value for FAC on admission for predicting outcomes was identified, suggesting the importance of gait ability assessment on admission.

Life satisfaction and awareness of meaningful activities among middle-aged adults: A population-based study

Introduction: Meaningful activities have been suggested to contribute to life satisfaction. Investigating the association between the awareness of meaningful activities and life satisfaction will help us develop a population-based occupational therapy strategy. The purpose of this study was to investigate the proportion of people who were aware of meaningful activities among middle-aged adults, and the relationship between the awareness of meaningful activities and life satisfaction. Method: A cross-sectional analysis was conducted on 2698 middle-aged adults who participated in an online survey conducted in Japan by the Y-Cloud system. Participants responded to demographic questions, life satisfaction, and awareness of meaningful activities. We examined the association between the awareness of meaningful activities and life satisfaction using binomial logistic regression analysis. Results: Of the respondents, 77.4% were aware of meaningful activities. Binomial logistic regression analysis adjusted for covariates showed that the awareness of meaningful activities was significantly associated with higher life satisfaction (odds ratio, 2.97; 95% confidence interval: 2.45–3.61, p &lt; 0.001). Conclusion: The results suggest the value of presenting that the awareness of meaningful activities should be considered in preventive population-based occupational therapy strategies for life satisfaction.

Intimate partner violence, depression, hazardous alcohol use, and social support among people with HIV initiating HIV care in Cameroon.

Intimate partner violence (IPV) has been associated with poor mental health among people with HIV (PWH) globally. Social support may be a strategy to foster mental health among PWH. Little is known about whether the relationship between IPV and mental health differs by IPV type or level of social support. Interviews were conducted with 426 PWH initiating HIV care in Cameroon. Log binomial regression analyses were used to estimate the association between four types of IPV (controlling behavior and emotional, physical, and sexual IPV) and symptoms of depression or hazardous alcohol use, separately by IPV type and level of social support. Over half (54.8%) of respondents experienced moderate/high levels of controlling behavior, 42.0% experienced emotional IPV, 28.2% experienced physical IPV and 23.7% experienced sexual IPV. Controlling behavior was associated with greater prevalence of depressive symptoms. This relationship did not vary meaningfully by level of social support (low: aPR 2.4 [95% CI 1.2, 4.9]; high: 1.7 [95% CI 1.0, 2.7]). Emotional and physical IPV were associated with greater prevalence of depressive symptoms among those with low social support (emotional IPV: aPR 1.9 [95% CI 1.0, 3.4]; physical IPV: aPR 1.8 [95% CI 1.2, 2.8]), but not among those with high social support (emotional IPV: aPR 1.0 [95% CI 0.7, 1.6]; physical IPV: aPR 1.0 [95% CI 0.6, 1.6]). Controlling behavior, emotional IPV, and physical IPV were associated with a greater prevalence of hazardous alcohol use, with moderately larger effect estimates among those with high compared to low social support. Sexual IPV was not associated with depressive symptoms or hazardous alcohol use. Services to screen and care for people experiencing IPV are urgently needed among PWH in Cameroon. Future research to identify barriers, feasibility, acceptability, and organizational readiness to integrate IPV and mental health services into HIV care settings is needed.

Group Multimodal Prenatal Care and Postpartum Outcomes.

An increasing body of evidence suggests equivalent if not improved postpartum outcomes of in-person group prenatal care compared with individual prenatal care. However, research is needed to evaluate outcomes of group multimodal prenatal care (GMPC), with groups delivered virtually in combination with individual in-person office appointments to collect vital signs and conduct other tests compared with individual multimodal prenatal care (IMPC) delivered through a combination of remotely delivered and in-person visits. To compare postpartum outcomes between GMPC and IMPC. A frequency-matched longitudinal cohort study was conducted at Kaiser Permanente Northern California, an integrated health care delivery system. Participants included 424 individuals who were pregnant (212 GMPC and 212 frequency-matched IMPC controls (matched on gestational age, race and ethnicity, insurance status, and maternal age) receiving prenatal care between August 17, 2020, and April 1, 2021. Participants completed a baseline survey before 14 weeks' gestation and a follow-up survey between 4 and 8 weeks post partum. Data analysis was performed from January 3, 2022, to March 4, 2024. GMPC vs IMPC. Validated instruments were used to ascertain postpartum psychosocial outcomes (stress, depression, anxiety) and perceived quality of prenatal care. Self-reported outcomes included behavioral outcomes (breastfeeding initiation, use of long-acting reversible contraception), satisfaction with prenatal care, and preparation for self and baby care after delivery. Primary analyses included all study participants in the final cohort. Three secondary dose-stratified analyses included individuals who attended at least 1 visit, 5 visits, and 70% of visits. Log-binomial regression and linear regression analyses were conducted. The final analytic cohort of 390 participants (95.6% follow-up rate of 408 singleton live births) was racially and ethnically diverse: 98 (25.1%) Asian/Pacific Islander, 88 (22.6%) Hispanic, 17 (4.4%) non-Hispanic Black, 161 (41.3%) non-Hispanic White, and 26 (6.7%) multiracial participants; median age was 32 (IQR, 30-35) years. In the primary analysis, after adjustment, GMPC was associated with a 21% decreased risk of perceived stress (adjusted risk ratio [ARR], 0.79; 95% CI, 0.67-0.94) compared with IMPC. Findings were consistent in the dose-stratified analyses. There were no significant differences between GMPC and IMPC for other psychosocial outcomes. While in the primary analyses there was no significant group differences in perceived quality of prenatal care (mean difference [MD], 0.01; 95% CI, -0.12 to 0.15) and feeling prepared to take care of baby at home (ARR, 1.09; 95% CI, 0.96-1.23), the dose-stratified analyses documented higher perceived quality of prenatal care (MD, 0.16; 95% CI, 0.01-0.31) and preparation for taking care of baby at home (ARR, 1.27; 95% CI, 1.13-1.43) for GMPC among those attending 70% of visits. No significant differences were noted in patient overall satisfaction with prenatal care and feeling prepared for taking care of themselves after delivery. In this cohort study, equivalent and, in some cases, better outcomes were observed for GMPC compared with IMPC. Health care systems implementing multimodal models of care may consider incorporating virtual group prenatal care as a prenatal care option for patients.

The Usefulness of Posterior Shiny Corner Lesions in the Early Diagnosis of Medial Meniscus Posterior Root Tears.

Posterior shiny corner lesions (PSCLs) have been reported to be useful for the early diagnosis of medial meniscus posterior root tears (MMPRTs) in surgical patients. However, the usefulness of PSCLs in outpatients, particularly regarding the optimal timing of magnetic resonance imaging (MRI) examinations after injury, remains unknown. We hypothesized that PSCLs would normally be observed in patients with MMPRTs within one month of injury. This study included 144 patients with knee pain who visited our hospital between January 2021 and May 2023. MRI findings within and after one month were examined. Fisher's exact test was performed for PSCLs, cleft signs, ghost signs, radial tear signs, bone cysts, and medial meniscus extrusion (MME), which are findings used for the diagnosis of MMPRTs. Time-dependent receiver operating characteristic (ROC) curve analysis was performed for each MRI finding. A binomial logistic regression analysis was performed for age, sex, PSCL, ghost sign, and MME. PSCLs were observed on 82.6% of the MRI scans within one month, but the positivity rate decreased after one month. After one month, a high percentage of patients had cleft signs and ghost signs. The results of a time-dependent ROC curve analysis showed that the PSCL had better diagnostic ability than the cleft sign, ghost sign, radial tear sign, and MME at a relatively early stage. Additionally, the area under the curve (AUC) of PSCL peaks around 35 days and then declines, reaching 0.8 or less around 40 days. On the other hand, the AUC of the cleft sign and ghost sign began to increase around 30 days after injury, and it exceeded 0.8 after approximately 100 days. The results of the binomial logistic regression analysis revealed significant PSCLs and ghost signs. Independent associations between the PSCL, or ghost sign, and the MMPRT were demonstrated. This study suggests that PSCLs have a superior diagnostic capability for MMPRT during the early stages of injury compared with other MRI findings in outpatients. In particular, PSCLs have a high positivity rate within one month after injury and a high diagnostic capacity up to 40 days after injury.

Age and schooling are associated with job loss in the initial months of the COVID-19 pandemic in Brazil

Brazil was one of the countries most affected by the social and economic crisis caused by the COVID-19 pandemic. This study aimed to verify the association between job loss and region of the country, sex, age, educational status, marital status, and parenting in Brazilian workers during the initial months of the COVID-19 pandemic. This cross-sectional online study was performed with data from workers aged 18 years or older in any economic sector and different occupations. A sociodemographic and occupational questionnaire was applied. Data collection began on June 2020 and ended on September 2020. To estimate the degree of association between job loss and the region of the country and workers’ characteristics, binomial logistic regression analysis was performed to obtain the odds ratio (OR) and confidence intervals. The sample was composed of 1319 participants and of these, 108 (8.2%) lost their jobs in the initial months of the pandemic; 51.6% were female; 53.5% were married; 42.5% reported having children; 80.7% had a complete college education. The age and educational status were associated with job loss, with younger and less educated workers being more affected by unemployment. For women, age and educational status were associated with job loss, for men only educational status showed a significant association. Young workers, mainly women, and with less educational status were the most affected by unemployment at the beginning of the pandemic in Brazil. Thus, this group of workers proved to be more vulnerable and should be prioritized by public policies.
