ABSTRACT

OBJECTIVE: To explore the relationship between the completion time of fluid resuscitation as well as negative fluid balance volumes and the prognosis of patients with septic shock, and to try to construct a prediction model based on the completion time of fluid resuscitation and negative fluid balance volumes, and to verify the predictive efficacy of the model on the prognosis of patients with septic shock.

METHODS: Patients with septic shock admitted to Wuxi People’s Hospital from April 2020 to April 2023 were selected. The general data (gender, age, body mass index, infection site), pathological indicators on admission, the difference of acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment (SOFA) between admission and 24 hours after fluid resuscitation, the completion time of fluid resuscitation and negative fluid balance volume were recorded. Multivariate Logistic analysis was used to screen the influencing factors of the prognosis of patients with septic shock, and a nomogram model was established. Bootstrap method was used for internal validation of the model. The consistency index, calibration curve and receiver operator characteristic curve (ROC curve) were used to evaluate the accuracy and prediction efficiency of the model.

RESULTS: A total of 96 patients with septic shock were enrolled, 38 patients died and 58 patients survived at 28 days. Compared with the survival group, the difference of APACHE II score, SOFA score, the proportion of fluid resuscitation completed within 1 to 3 hours, and the proportion of negative fluid balance volume -500 to -250 mL per day in the death group were lower, and the differences were statistically significant (all P < 0.05). Multivariate Logistic analysis showed that the completion time of fluid resuscitation was a risk factor for the prognosis of patients with septic shock [odds ratio (OR) = 26.285, 95% confidence interval (95%CI) was 9.984-76.902, P < 0.05]. The difference of APACHE II score (OR = 0.045, 95%CI was 0.015-0.131), SOFA score (OR = 0.056, 95%CI was 0.019-0.165) between admission and 24 hours after fluid resuscitation, and negative fluid balance volume (OR = 0.043, 95%CI was 0.015-0.127) were protective factors for the prognosis of patients with septic shock (all P < 0.05). The model validation results showed that the consistency index was 0.681 (95%CI was 0.596-0.924), indicating good discrimination. The calibration curve showed that the calibration curve fitted well with the ideal curve. The ROC curve showed that the sensitivity of the nomogram model for predicting the death of patients with septic shock was 83.7%, the specificity was 97.2%, and the area under the ROC curve (AUC) was 0.931 (95%CI was 0.846-0.985), indicating that the model had good prediction efficiency.

CONCLUSIONS: The completion time of fluid resuscitation and negative fluid balance volumes are related to the prognosis of septic shock patients, and the alignment diagram model improve the identification of the risk of death in septic shock patients.

ABSTRACT

INTRODUCTION: Breast cancer is the leading cause of neoplasm mortality among women. Several prevention strategies have been implemented to early detect and prevent the cancer occurrence. The most effective protocol includes prevention mastectomy for the high-risk patients. In our study, we have compared the efficacy of subcutaneous mastectomy (SCM) and skin sparing mastectomy (SSM) in long-term follow up.

METHODS: We have included 201 female patients who have been treated at our department over the course of 20 years between 2000 and 2019. All the patients were at high risk of developing breast cancer and therefore were indicated for the prophylactic mastectomy. The main indication was the presence of the mutation in the BRCA1 or BRCA2 cluster, however, even in the lack of such mutation, the family history was sufficient for the mastectomy indication. Patients underwent either SCM, SSM or areola sparing mastectomy (ASM), and were allocated to aforementioned groups, respectively. We have collected the data regarding the reconstruction method along with age, weight, height, body mass index (BMI) and presence of predisposing genetic mutations such as BRCA positivity.

RESULTS: The patients who underwent SSM compared to those who underwent SCM were of higher age, with higher BMI and body mass. The patients in SSM group had statistically significantly higher BMI than in ASM. There was no difference in efficacy between patients who underwent SSM and SCM. The majority of patients (91.5%) were positive for BRCA1 or BRCA2 mutation. In our study, only four patients were tested negative for known breast cancer inducing mutation (three in SCM and one in SSM). The most common reconstruction method was an abdominal flap and breast implant.

CONCLUSIONS: Prophylactic mastectomy is a reliable strategy for significantly reducing the number of breast cancer incidence in high-risk patients regardless of the selected method of mastectomy. These operations allow for the subsequent reconstruction with the whole spectrum of reconstructive options.

ABSTRACT

OBJECTIVE: This study was carried out to determine the mediating role of physician trust in the relationship between medical mistrust and health-care system distrust.

MATERIALS AND METHODS: The “Health Care Systems Distrust Scale”, which consists of 10 questions, the “Medical Mistrust Scale”, which consists of 17 questions, the “Physician Trust Scale”, which consists of 11 questions. The statistical analysis was performed using the SPSS 26.0 program.

RESULTS: Health-care system distrust was positively correlated with medical mistrust and negatively correlated with physician trust. There was a negative relationship between medical mistrust and physician trust. Physician trust mediates the effect of medical mistrust on health-care system distrust. In other words, it was determined that the mediating effect of physician trust was significant.

CONCLUSION: Addition of physician trust to medical mistrust decreases the negative effects of health-care system distrust. Medical mistrust must be addressed at multiple levels of society, including government, policy, and health-care systems.

ABSTRACT

OBJECTIVE: This study aims to compare the effects of microscopic microdiscectomy and microendoscopic discectomy on pain, disability, fear of falling, kinesiophobia, anxiety, quality of life in patients with lumbar disc herniation (LDH).

METHODS: A total of 90 patients who underwent microscopic microdiscectomy (n = 40) and microendoscopic discectomy (n = 50) for LDH were included in this study. The patients’ pain, disability, fear of falling, kinesiophobia, anxiety, and quality of life were evaluated before the surgery, in the early postoperative period and three months after.

RESULTS: In patients who underwent microendoscopic discectomy, the results of pain, disability, fear of falling, kinesiophobia and anxiety were statistically decreased compared with the microscopic microdiscectomy in the early postoperative period and three months later (p < 0.05). Also, a statistically higher increase was observed in the general health perception of patients who underwent microendoscopic discectomy three months after the operation (p < 0.01).

CONCLUSION: Microendoscopic microdiscectomy, remains the most effective and widely applied method with advantages on pain, quality of life, and improved physical functions.

ABSTRACT

OBJECTIVE: The aim of this study was to assess the risk factors associated with 30-day hospital readmissions after a cholecystectomy.

METHODS: We conducted a case-control study, with data obtained from UC-Christus from Santiago, Chile. All patients who underwent a cholecystectomy between January 2015 and December 2019 were included in the study. We identified all patients readmitted after a cholecystectomy and compared them with a randomized control group. Univariate and multivariate analyses were conducted to identify risk factors.

RESULTS: Of the 4866 cholecystectomies performed between 2015 and 2019, 79 patients presented 30-day hospital readmission after the surgical procedure (1.6%). We identified as risk factors for readmission in the univariate analysis the presence of a solid tumor at the moment of cholecystectomy (OR = 7.58), high pre-operative direct bilirubin (OR = 2.52), high pre-operative alkaline phosphatase (OR = 3.25), emergency admission (OR = 2.04), choledocholithiasis on admission (OR = 4.34), additional surgical procedure during the cholecystectomy (OR = 4.12), and post-operative complications. In the multivariate analysis, the performance of an additional surgical procedure during cholecystectomy was statistically significant (OR = 4.24).

CONCLUSION: Performing an additional surgical procedure during cholecystectomy was identified as a risk factor associated with 30-day hospital readmission.

ABSTRACT

US Latine adults who prefer the Spanish language for healthcare encounter communication have high risk of health disparitiesm in part from low organizational health literacy, mental health stigma and discrimination. Latine organizational health literacy includes the provision of culturally responsive, language concordant health information, which supports good comprehension and could mitigate some health disparities. We conducted a pilot study to assess commonly provided patient health information handouts about depression treatment and antidepressant consumer medication information sheets. Thirty Latine adults with a Spanish language preference and a history of depression and antidepressant use participated in one phone interview. Descriptive statistics and thematic analysis were used to assess comprehension and usefulness of selected sections extracted verbatim from these documents. Overall, 83% (n = 25) participants reported that all sections were easy to understand and 97% (n = 29) said that they were useful. Yet, responses to open-ended questions for 53% (n = 16) of revealed ‘confusing’ terminology in at least one section, and 10% (n = 3) expressed concerns about or misunderstood an idiomatic phrase as reinforcing stigma. The organizational health literacy-based issues identified in this and previous studies require that government and health service organizations make necessary and timely revisions to address them.

ABSTRACT

There is a pressing need for ecologically valid versions of traditional neuropsychological tests indexing executive function (EF), such as the Trail-Making Task (TMT), that incorporate movement and bodily awareness in healthy participants with varying abilities. We designed a proprioceptive version of the TMT (pTMT) that involved coordinated gross motor movement and proprioceptive awareness to investigate whether this measure of visual attention, task switching, and working memory positively correlated with a computerized version of the TMT (the dTMT). We aimed to establish the initial validity of our proprioceptive TMT (pTMT) by comparing performances on the dTMT and pTMT among a cohort of 36 healthy participants (18 dancers, 18 non-dancers; M age = 22, SD = 5.27; 64% female) anticipating that dancers would express higher intrinsic bodily awareness than non-dancers. Results revealed a mild to moderate but statistically significant positive correlation between dTMT and pTMT completion times [part A: r (36) = .33, p = .04; part B: r (36) = .37, p = .03] and numbers of errors [part B: r (36) = .41, p = .01] across both participant groups. These data suggest partial measurement convergence between these two TMT versions. Relative to non-dancers, dancers exhibited a higher level of performance (likely due to their better proprioceptive ability) through their faster completion times on dTMT-B [t (34) = 3.81, p = .006, d = 1.27] and pTMT-B [t (34) = 2.97, p = .005, d = .99], and their fewer errors on dTMT-B [t (34) = 2.93, p = .006, d = 1.0]. By identifying cognitive differences between these different groups of healthy individuals, our data contribute to both a theoretical understanding and the initial development of gross motor movement-based cognitive assessments, providing a path toward the further refinement of an ecologically valid full-body TMT.

ABSTRACT

PURPOSE: To compare giredestrant and physician’s choice of endocrine monotherapy (PCET) for estrogen receptor-positive, HER2-negative, advanced breast cancer (BC) in the phase II acelERA BC study (ClinicalTrials.gov identifier: NCT04576455).

METHODS: Post-/pre-/perimenopausal women, or men, age 18 years or older with measurable disease/evaluable bone lesions, whose disease progressed after 1-2 lines of systemic therapy (≤1 targeted, ≤1 chemotherapy regimen, prior fulvestrant allowed) were randomly assigned 1:1 to giredestrant (30 mg oral once daily) or fulvestrant/aromatase inhibitor per local guidelines (+luteinizing hormone-releasing hormone agonist in pre-/perimenopausal women, and men) until disease progression/unacceptable toxicity. Stratification was by visceral versus nonvisceral disease, prior cyclin-dependent kinase 4/6 inhibitor, and prior fulvestrant. The primary end point was investigator-assessed progression-free survival (INV-PFS).

RESULTS: At clinical cutoff (February 18, 2022; median follow-up: 7.9 months; N = 303), the INV-PFS hazard ratio (HR) was 0.81 (95% CI, 0.60 to 1.10; P = .1757). In the prespecified secondary end point analysis of INV-PFS by ESR1 mutation (m) status in circulating tumor DNA-evaluable patients (n = 232), the HR in patients with a detectable ESR1m (n = 90) was 0.60 (95% CI, 0.35 to 1.03) versus 0.88 (95% CI, 0.54 to 1.42) in patients with no ESR1m detected (n = 142). Related grade 3-4 adverse events (AEs), serious AEs, and discontinuations due to AEs were balanced across arms.

CONCLUSION: Although the acelERA BC study did not reach statistical significance for its primary INV-PFS end point, there was a consistent treatment effect with giredestrant across most key subgroups and a trend toward favorable benefit among patients with ESR1-mutated tumors. Giredestrant was well tolerated, with a safety profile comparable to PCET and consistent with known endocrine therapy risks. Overall, these data support the continued investigation of giredestrant in other studies.
