Risk factors for post-cerebral infarction cognitive dysfunction in older adults: a retrospective study.

OBJECTIVE: Our research aims to elucidate the significance of type 2 diabetes (T2D) and provides an insight into a novel risk model for post-cerebral infarction cognitive dysfunction (PCICD). METHODS: Our study recruited inpatients hospitalized with cerebral infarction in Xijing hospital, who underwent cognitive assessment of Mini-Mental State Examination (MMSE) from January 2010 to December 2021. Cognitive status was dichotomized into normal cognition and cognitive impairment. Collected data referred to Demographic Features, Clinical Diseases, scale tests, fluid biomarkers involving inflammation, coagulation function, hepatorenal function, lipid and glycemic management. RESULTS: In our pooled dataset from 924 eligible patients, we included 353 in the final analysis (age range 65-91; 30.31% female). Multivariate logistic regression analysis was performed to show that Rural Areas (OR = 1.976, 95%CI = 1.111-3.515, P = 0.020), T2D (OR = 2.125, 95%CI = 1.267-3.563, P = 0.004), Direct Bilirubin (OR = 0.388, 95%CI = 0.196-0.769, P = 0.007), Severity of Dependence in terms of Barthel Index (OR = 1.708, 95%CI = 1.193-2.445, P = 0.003) that were independently associated with PCICD, constituting a model with optimal predictive efficiency. CONCLUSION: To the best of our knowledge, this study provides a practicable map of strategical predictors to robustly identify cognitive dysfunction at risk of post-cerebral infarction for clinicians in a broad sense. Of note, our findings support that the decline in serum direct bilirubin (DBil) concentration is linked to protecting cognitive function.

Self-Balancing Exoskeleton Robots Designed to Facilitate Multiple Rehabilitation Training Movements.

This study presents the biomimetic design of the structure and controller of AutoLEE-II, a self-balancing exoskeleton developed to assist patients in performing multiple rehabilitation movements without crutches or other supporting equipment. Its structural design is founded upon the human body structure, with an eliminated axis deviation and a raised CoM of the exoskeleton. The controller is a physical parameter-independent controller based on the CoM modification. Thus, the exoskeleton can adapt to patients with different physical parameters. Five subjects underwent exoskeleton-assisted rehabilitation training experiments, including squatting, tilting, and walking trainings. The results showed that the exoskeleton can assist patients in completing various rehabilitation exercises and help them maintain their balance during the rehabilitation training. This helpful role of the exoskeleton in rehabilitation training is analyzed through an electromyography (EMG) data analysis. The findings revealed that wearing the exoskeleton can reduce the activity of the lower limb muscles by approximately 20-30% when performing the same rehabilitation exercises.

Therapeutic strategies targeting folate receptor α for ovarian cancer.

Epithelial ovarian cancer (EOC) is the deadliest gynecological cancer, and presents a major clinical challenge due to limited treatment options. Folate receptor alpha (FRα), encoded by the FOLR1 gene, is an attractive therapeutically target due to its prevalent and high expression in EOC cells. Recent basic and translational studies have explored several modalities, such as antibody-drug conjugate (ADC), monoclonal antibodies, small molecules, and folate-drug conjugate, to exploit FRα for EOC treatment. In this review, we summarize the function of FRα, and clinical efficacies of various FRα-based therapeutics. We highlight mirvetuximab soravtansine (MIRV), or Elahere (ImmunoGen), the first FRα-targeting ADC approved by the FDA to treat platinum-resistant ovarian cancer. We discuss potential mechanisms and management of ocular adverse events associated with MIRV administration.

Multimorbidity Patterns and Associations with Gait, Balance and Lower Extremity Muscle Function in the Elderly: A Cross-Sectional Study in Northwest China.

Purpose: Fall is a common geriatric syndrome leading to various adverse outcomes in the elderly. Gait and balance disorders and decreased lower extremity muscle function are the major intrinsic risk factors of falls, and studies suggested that they were closely related to the underlying chronic conditions. This study aimed to explore the patterns of multimorbidity and determine the associations of these multimorbidity patterns with gait, balance and lower extremity muscle function. Patients and Methods: A cross-sectional survey of 4803 participants aged ≥60 years in Shaanxi Province, China was conducted and the self-reported chronic conditions were investigated. The 6-m walk test, timed-up-and-go test (TUG) and 5-sit-to-stand test (5-STS) were conducted to evaluate gait, balance, and lower extremity muscle function respectively. Latent class analysis was used to explore patterns of multimorbidity, and multivariate regression analysis was used to determine the associations of multimorbidity patterns with gait, balance, and lower extremity muscle function. Results: Five multimorbidity patterns were identified: Degenerative Disease Class, Cardio-metabolic Class, Stroke-Respiratory-Depression Class, Gastrointestinal Class, and Very sick Class, and they were differently associated with gait and balance disorders and decreased lower extremity muscle function. In particular, the multimorbidity patterns of Degenerative Disease Class and Stroke-Respiratory-Depression Class were closely associated with all the three risk factors of falls. Conclusion: There are significant differences in the impact of different multimorbidity patterns on the major intrinsic risk factors of falls in the elderly population, and appropriate multimorbidity patterns are closely related to the prediction of falls and can help to develop fall prevention strategies in the elderly.

Pseudo-pseudo Meigs syndrome in systemic lupus erythematosus misdiagnosed as pseudo-Meigs' syndrome: A case report.

Symptoms of pelvic masses, elevated serum CA125 levels, massive ascites, and pleural effusion in female patients are usually associated with malignancy. Some benign ovarian tumors or other nonmalignant tumors may also produce similar symptoms, called Meigs syndrome or pseudo-Meigs' syndrome, which should be one of the differential diagnoses. However, there is an extremely rare form of SLE called pseudo-pseudo Meigs syndrome (PPMS), which may also present with the above symptoms, but is not associated with any of the tumors. In this paper, we report a case of a 47-year-old woman who presented with abdominal distention. The patient was found to have elevated serum CA125 levels to 182.9 U/mL before the operation. Her PET-CT suggested a large heterogeneous mass in the pelvis measuring 8.2 × 5.8 cm with a large amount of ascites. She was initially diagnosed with ovarian cancer and underwent exploratory laparotomy. Pathology of the surgical specimen revealed a uterine leiomyoma. Two months after discharge, the patient's ascites reappeared along with recurrent intestinal obstruction. After ascites and serological tests, she was eventually diagnosed with systemic lupus erythematosus and received systemic hormonal therapy.

Highly Efficient Refractive Index Sensor Based on a Dual-Side Polished SMS Fiber Enabled by Femtosecond Laser Writing.

Fiber-optic refractive index (RI) sensors based on wavelength-shift-based interrogation continue to present a challenge in achieving high sensitivity for a wide detection range. In this paper, we propose a sensor for determining the RI of liquids based on femtosecond laser (fs-laser) writing of a dual-side polished singlemode-multimode-singlemode (SMS) fiber. The proposed sensor can determine the RI value of a surrounding liquid by detecting the dip wavelength in the transmission spectrum of the light propagating through the sensing area. The high RI sensitivity is attributed to the increased interaction area established by the fs-laser, which creates hydrophilic surfaces and maintains the wide detection range of the SMS structure. The results of the wavelength-shift-based interrogation reveal that the fabricated device exhibited a high sensitivity of 161.40 nm per refractive index unit (RIU) over a wide RI detection range of 0.062 RIU. The proposed device has high processing accuracy and a simple manufacturing process. Hence, it has the potential to be used as a lab-on-fiber sensing platform in chemical and biotechnological applications.

Application and evaluation of transitory protective stoma in ovarian cancer surgery.

Ovarian cancer is the most fatal of all female reproductive cancers. The fatality rate of OC is the highest among gynecological malignant tumors, and cytoreductive surgery is a common surgical procedure for patients with advanced ovarian cancer. To achieve satisfactory tumor reduction, intraoperative bowel surgery is often involved. Intestinal anastomosis is the traditional way to restore intestinal continuity, but the higher rate of postoperative complications still cannot be ignored. Transitory protective stoma can reduce the severity of postoperative complications and traumatic stress reaction and provide the opportunity for conservative treatment. But there are also many problems, such as stoma-related complications and the impact on social psychology. Therefore, it is essential to select appropriate patients according to the indications for the transitory protective stoma, and a customized postoperative care plan is needed specifically for the stoma population.

Development and Evaluation of a Lumbar Assisted Exoskeleton With Mixed Lifting Tasks by Various Postures.

A large number of the WRLSs (wearable robots lumbar support) research have been presented for working efficient increase and injure risk reduction in recent years. However, the previous research can only complete the sagittal-plane lifting task, which can not adapt to the mixed lifting tasks in the actual work scene. Therefore, we presented a novel lumbar assisted exoskeleton with mixed lifting tasks by various postures based on position control, which can not only carry out the lifting tasks of sagittal-plane, but also complete the lifting tasks of sides. First, we proposed a new generation method of raising reference curves that can generate assistance curve for each user with each task, which is very convenient in mixed lifting tasks. Then, an adaptive predictive controller was designed to track the reference curves of different users under different loads, the maximum tracking errors of the angles are 2.2° and 3.3° respectively at 5kg and 15kg, and all the errors are within 3%. Compared to the condition of no exoskeleton, the average RMS (root mean square) of EMG (electromyography) for six muscles are reduced by 10.33±1.44% , 9.62±0.69% , 10.97±0.81% and 14.48±2.11% by lifting loads with stoop, squat, left-asymmetric and right-asymmetric respectively. The results demonstrate that our lumbar assisted exoskeleton presents outperformance in mixed lifting tasks by various postures.

Efficacy of Oral Medications or Intrauterine Device-Delivered Progestin in Patients with Endometrial Hyperplasia with or without Atypia: A Network Meta-Analysis.

The aim of this systematic review was to evaluate the efficacy of oral medication or intrauterine device-delivered progestins in patients with endometrial hyperplasia (EH) with or without atypia. We systematically examined PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov to identify studies reporting the regression rate of patients with EH who received progestins or non-progestins. The regression rates after different treatments were compared using a network meta-analysis in terms of the relative ratios (RRs) and 95% confidence intervals (CIs). Begg-Mazumdar rank correlation and funnel plots were performed to evaluate the publication bias. Five non-randomized studies and 21 randomized controlled trials involving 2268 patients were included in the network meta-analysis. The levonorgestrel-releasing intrauterine system (LNG-IUS) was associated with a higher regression rate than medroxyprogesterone acetate (MPA) (RR 1.30, 95% CI 1.16-1.46) in patients with EH. Among those without atypia, the LNG-IUS was associated with a higher regression rate than any of the three types of oral medications (MPA, norethisterone, or dydrogesterone (DGT)) (RR 1.35, 95% CI 1.18-1.55). According to the network meta-analysis, combining the LNG-IUS with MPA or metformin increased regression rate, while DGT was associated with the highest regression rate among all oral medications. The LNG-IUS may be the best choice for patients with EH, and combining it with MPA or metformin may further improve its efficacy. DGT may be the preferred choice for patients who are unwilling to use the LNG-IUS or who cannot tolerate its side effects.

Recurrence and survival of patients with stage III endometrial cancer after radical surgery followed by adjuvant chemo- or chemoradiotherapy: a systematic review and meta-analysis.

OBJECTIVE: To compare recurrence and survival in patients with stage III endometrial cancer after radical surgery, followed by either adjuvant chemoradiotherapy (ACR) or adjuvant chemotherapy (AC). METHODS: We searched for relevant studies in PubMed Central, Embase and the Cochrane Central Register of Controlled Trials. Data were pooled on rates of recurrence as well as rates of progression-free, disease-free and overall survival. Heterogeneity was evaluated using the I2 test. Subgroup and sensitivity analyses were performed to identify potential sources of heterogeneity. RESULTS: Data from 18,375 patients in 15 retrospective studies and one randomized controlled trial were meta-analyzed. Compared to the AC group, the ACR showed significantly lower risk of local recurrence (OR 0.43, 95%CI 0.32-0.59) and total recurrence (OR 0.72, 95%CI 0.58-0.89). ACR was also associated with significantly better overall survival (HR 0.66, 95%CI 0.57-0.76), progression-free survival (HR 0.56, 95%CI 0.39-0.81) and disease-free survival (HR 0.66, 95%CI 0.53-0.83). CONCLUSIONS: Adding adjuvant radiotherapy to adjuvant chemotherapy after radical surgery may significantly reduce risk of local and overall recurrence, while significantly improving survival of patients with stage III endometrial cancer.

Knowledge Transmission and Skills Building Relating to Child Sexual Abuse in China.

Parents play a key role in child CSA prevention, but the mechanisms underlying the intergenerational knowledge transmission are not fully understood. This study explores the role of two parenting practices - parent-child communication and parent's protective behavior - as mediating factors in the relation between parents' knowledge and their children's knowledge and skills. Four hundred and ten dyads of early adolescents and their mother or father from rural China participated in the study. Parents were surveyed on their knowledge, protective behaviors, and parent-child communication regarding CSA, while children answered questions on relevant knowledge and skills. Results revealed that parental knowledge was positively and significantly related to communication and protective behavior, protective behavior was positively related to children's knowledge and skills, but the coefficient between communication and children's knowledge and skills was insignificant. The findings highlight direct parental protection as one of the most important mechanism for intergenerational knowledge transmission.

Digital twin rehabilitation system based on self-balancing lower limb exoskeleton.

BACKGROUND: The digital twin concept is the virtual model based on entity design measures, which is used in many enterprises' virtual workshop design models for workshop production scheduling and optimization. However, in the field of medical rehabilitation, the integration of digital twin technology started late compared to traditional industrial manufacturing. Many current digital models are not well suited for information interaction between patients and devices. OBJECTIVE: In order to address the lack of interaction between patients and devices in the field of medical rehabilitation, this paper proposes an automatic gait data control system (AGDCS) for fully actuated lower limb exoskeleton digital twinning. This system improves the integration of digital twinning system with the medical rehabilitation field and analyzes the patient's gait data through simulation experiments. METHODS: The digital twin system was designed in several steps. Firstly, the upper computer function module was designed and developed according to the rehabilitation treatment needs. After that, the combination of exoskeleton robot and software was carried out, and finally the real rehabilitation treatment environment of patients was simulated through experiments. RESULTS: The proposed system was very reliable in the experimental tests of the host computer and exoskeleton robot. In the upper computer test, the patient specific gait can be generated, and the motion of the exoskeleton robot can be observed in real-time. During the walking test of the exoskeleton robot, the exoskeleton robot completed the specified gait. The result verified the superiority and effectiveness of the digital twin system AGDCS in the field of rehabilitation. CONCLUSIONS: The digital twin system proposed in this paper improves the interaction between self-balancing exoskeleton robot and patients, and improves the autonomy and safety of patients in rehabilitation treatment.

Risk factors and current state of therapy for anemia after kidney transplantation.

Post-transplant anemia is one of the most common complications in kidney transplant recipients, severely affecting patient prognosis and quality of life, and is an independent predictor of graft kidney loss and patient mortality. However, our clinical understanding and the attention given to post-transplant anemia are currently insufficient. This paper reviews the current status, risk factors, and therapeutic progress in anemia after transplantation in kidney transplant recipients. We recommend that clinical staff pay attention to anemia and its complications in kidney transplant recipients and intervene early for anemia.
