Surgical Technique for Complementing Robotic-Assisted Total Knee Arthroplasty in Middle-Aged Patients with Rigid Knee Bones.

This study reports 12 cases of inaccurate bone cutting from a single-surgeon series of 509 consecutively performed robotic-assisted total knee arthroplasty (TKA) for 1 year. In addition, a complementary technique with the combined benefits of robotic-assisted and manual techniques that address this issue is described. From June 2020 to May 2021, a consecutive series of 509 TKAs was performed on 338 patients using a posterior-stabilized total knee prosthesis with a robotic-assisted system at our hospital. The surgical records were reviewed to identify the causative bone locations and bone re-cutting events correlated with improper trial instrument positioning. The re-cutting rate was 2.4% (12/509). All re-cutting attempts occurred because of improper cutting of the femoral posterior chamfer. Re-cutting was attempted mostly on middle-aged male patients. This complementary technique can facilitate manual bone cutting while retaining the advantages of robotic surgery during robotic-assisted TKA. Additionally, the combined technique of manual bone cutting and robotic-assisted surgery can be a useful alternative for middle-aged male patients with rigid knee bones.

Sleep quality in middle-aged and elderly hemodialysis patients: Impact of a structured nursing intervention program.

Poor sleep quality is common among hemodialysis patients and can significantly impact their well-being. This study aimed to evaluate the effectiveness of a structured nursing intervention program in improving sleep quality in middle-aged and elderly hemodialysis patients. To evaluate the impact of nursing intervention on sleep quality in hemodialysis patients. This cross-sectional study was conducted in a tertiary hospital, the First Affiliated Hospital of Nanchang University, in 2023. This study included 105 middle-aged and elderly hemodialysis patients aged ≥ 45 years who underwent maintenance hemodialysis for at least 3 mo, utilizing the Pittsburgh Sleep Quality Index (PSQI) to identify poor sleepers. Those identified underwent a 12-wk nursing intervention program focusing on education, relaxation techniques, and counseling. Post-intervention, sleep quality was reassessed using the PSQI. The study found that 68.6% of hemodialysis patients were poor sleepers. Following the 12-wk nursing intervention program, there was a significant decrease in the mean global PSQI score from 8.9 ± 3.2 to 5.1 ± 2.7 (P < 0.001), indicating improved sleep quality. This demonstrated the effectiveness of the structured nursing intervention in enhancing sleep quality for middle-aged and elderly hemodialysis patients. The structured nursing intervention program focusing on sleep hygiene education, relaxation techniques, and counseling effectively improved sleep quality among middle-aged and elderly hemodialysis patients. The significant decrease in the mean global PSQI score post-intervention indicates the positive impact of tailored nursing interventions in addressing poor sleep quality in this patient population. These findings emphasize the importance of implementing targeted nursing interventions to enhance the quality of life for hemodialysis patients by addressing the prevalent issue of poor sleep quality.

Association of waist-to-hip ratio adjusted for body mass index with cognitive impairment in middle-aged and elderly patients with type 2 diabetes mellitus: a cross-sectional study

BackgroundNumerous reports indicate that both obesity and type 2 diabetes mellitus (T2DM) are factors associated with cognitive impairment (CI). The objective was to assess the relationship between abdominal obesity as measured by waist-to-hip ratio adjusted for body mass index (WHRadjBMI) and CI in middle-aged and elderly patients with T2DM.MethodsA cross-sectional study was conducted, in which a total of 1154 patients with T2DM aged ≥ 40 years were included. WHRadjBMI was calculated based on anthropometric measurements and CI was assessed utilizing the Montreal Cognitive Assessment (MoCA). Participants were divided into CI group (n = 509) and normal cognition group (n = 645). Correlation analysis and binary logistic regression were used to explore the relationship between obesity-related indicators including WHRadjBMI, BMI as well as waist circumference (WC) and CI. Meanwhile, the predictive power of these indicators for CI was estimated by receiver operating characteristic (ROC) curves.ResultsWHRadjBMI was positively correlated with MoCA scores, independent of sex. The Area Under the Curve (AUC) for WHRadjBMI, BMI and WC were 0.639, 0.521 and 0.533 respectively, and WHRadjBMI had the highest predictive power for CI. Whether or not covariates were adjusted, one-SD increase in WHRadjBMI was significantly related to an increased risk of CI with an adjusted OR of 1.451 (95% CI: 1.261–1.671). After multivariate adjustment, the risk of CI increased with rising WHRadjBMI quartiles (Q4 vs. Q1 OR: 2.980, 95%CI: 2.032–4.371, P for trend < 0.001).ConclusionsOur study illustrated that higher WHRadjBMI is likely to be associated with an increased risk of CI among patients with T2DM. These findings support the detrimental effects of excess visceral fat accumulation on cognitive function in middle-aged and elderly T2DM patients.

Effect of different anesthesia depths on perioperative heart rate variability and hemodynamics in middle-aged and elderly patients undergoing general anesthesia

BackgroundTo analyze the effects of different anesthesia depths on perioperative heart rate variability and hemodynamics in middle-aged and elderly patients undergoing general anesthesia, and to provide a basis for clinical application.MethodsA total of 111 patients with gastric cancer who were treated with epidural anesthesia combined with general anesthesia were selected as the study subjects, and the patients were randomly divided into group A, group B and group C. The bispectral index (BIS) was maintained by adjusting the infusion speed of anesthetics, the BIS of group A was maintained at 50 ~ 59, the BIS of group B was maintained at 40 ~ 49, and the BIS of group C was maintained at 30 ~ 39. The high-frequency power (HFP), low-frequency power (LFP), total power (TP), mean arterial pressure (MAP), heart rate (HR), diastolic blood pressure (DBP), and systolic blood pressure (SBP) were measured before anesthesia induction (T1), immediately after intubation (T2), 3 min after intubation (T3), and 6 min after extubation (T4). The cognitive function of the patients was evaluated before and 48 h after surgery.ResultsThe HFP, LFP/HFP, TP, HR, DBP and SBP between the three groups at T1 ~ T3 are significantly difference from each other (P < 0.05). There were significant differences in spontaneous breathing recovery time, eye opening time and extubation time among group A, B and C groups, and group B had the lowest spontaneous breathing recovery time, eye opening time and extubation time (P < 0.05). There was no significant difference in the incidence of adverse reactions during anesthesia between the three groups. The cognitive function score of group B was significantly higher than that of group A and group C (P < 0.05).ConclusionsBIS maintenance of 40 ~ 49 has little effect on perioperative heart rate variability and hemodynamics in middle-aged and elderly patients undergoing general anesthesia, which is helpful for postoperative recovery.

Comparing the imaging characteristics of middle-aged patients with multiple sclerosis and CADASIL: A retrospective cross-sectional study

BackgroundFew studies have quantitatively analyzed the imaging disparities between multiple sclerosis (MS) and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We aimed to compare the imaging characteristics of MS and CADASIL in middle-aged patients. Materials and MethodsThis retrospective study used a single-center database and included patients aged 40–60 years with MS and CADASIL who underwent the designated imaging protocol including 3D T1-weighted imaging and fluid attenuated inversion recovery (FLAIR), diffusion tensor imaging and susceptibility-weighted imaging between January 2018 and March 2023. Patients with MRI-detected macrobleeds were excluded. ResultsA total of 27 patients with MS (mean age, 46.7 years ± 4.4, 8 men) and 30 patients with CADASIL (mean age, 51.6 years ± 5.8, 14 men) were included. No significant differences were observed in the Fazekas grades of white matter lesions (WMLs). Patients with CADASIL exhibited greater external capsule involvement (56.7% vs.18.5 %; p = 0.006), whereas the MS group had more lesions in the corpus callosum (81.5% vs. 53.3 %, p = 0.02) and brainstem (74.1% vs. 46.7 %, p = 0.04). The CADASIL group exhibited a higher incidence of microbleeds (12.07 vs. 0.11, p = 0.001). The WMLs in the MS group exhibited a lower T1 lesion/cerebrospinal fluid signal index (2.206 vs. 2.882, p < 0.001). A value of ≤2.57 demonstrated a sensitivity of 92.6 % and a specificity of 90.0 % in differentiating MS. Patients with MS had a thinner corpus callosum (7.18 mm vs 7.86 mm, p = 0.04), while patients with CADASIL showed significantly higher mean diffusivity (0.8776 × 10–3 vs. 0.7637 × 10–3 mm2/s, p = 0.03) and lower fractional anisotropy (0.7581 vs. 0.8389, p = 0.04) in the splenium of the corpus callosum. ConclusionMiddle-aged patients with MS and CADASIL showed comparable Fazekas grades for WMLs. However, lesion distribution, T1 signal characteristics, and splenic diffusivity changes can help differentiate between MS and CADASIL.

The Effect of Different Sensory Perturbations on Postural Control and Fall Risk in Benign Paroxysmal Positional Vertigo Patients.

Benign paroxysmal positional vertigo (BPPV) patients may experience balance problems in various environmental conditions other than positional dizziness. Therefore, there is a need to investigate the postural control abilities and the ability to use sensory inputs in BPPV patients in different conditions. The aim of this study was to examine the postural control performance of middle-aged adult BPPV patients in easy and difficult balance tasks, the effect of vestibular stimulation on the maintenance of balance, and the risk of falling, by posturographic evaluation in various conditions. A total of 26 patients diagnosed with posterior canal BPPV and 26 controls were included in the study. Sensory Organization Test (SOT), Vestibular Stimulation Test (VST), and fall risk assessment (FRA) were applied to the participants, respectively. Significant difference was observed in SOT medio-lateral (ML) plane in Conditions 2 and 5 (p < .05). A significant difference was observed in the vestibular score in the SOT ML plane. No significant difference was observed in VST test scores (p > .05). In the FRA test, a significant difference was observed in the energy and gain parameters in the anterio-posterior plane (p < .05). The current study examined postural control abilities of patients with BPPV in extensive external conditions and in both planes, using various sensory perturbations and stimulation. It was thought that while BPPV patients were in the active phase of the disease, their postural control skills in the ML plane decreased and they might be at risk of falling.

Impact of ultra-early enteral nutrition support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage

To investigate the effect of ultra-early enteral nutrition (UEEN) support on the prognosis of young and middle-aged postoperative patients with cerebral hemorrhage. The clinical data of young and middle-aged patients (aged 18-59 years) admitted to Tianjin Fifth Central Hospital from January 2020 to June 2023 after surgery for intracerebral hemorrhage were retrospectively analyzed, and the general data, nutritional indexes, gastrointestinal complications, neurological function recovery and long-term prognosis of the patients were recorded. According to the time of initiation of enteral nutrition (EN) support, patients were divided into UEEN group (EN implementation within 12 hour after surgery) and early enteral nutrition (EEN) group (EN implementation within 24 to 48 hour after surgery). The differences of the above indexes between the two groups were analyzed and compared. A total of 64 young and middle-aged postoperative patients with cerebral hemorrhage were enrolled, including 32 cases in the UEEN group and 32 cases in the EEN group. There were no significant differences in gender, age, proportion of hypertension and diabetes, Glasgow coma score (GCS) on admission and surgical methods between the two groups. In terms of nutritional indexes, serum total protein, albumin and hemoglobin levels of patients in both groups on day 7 after admission were lower than those on day 1, and higher than those on day 3, and the above indexes levels in UEEN group were significantly higher than those in EEN group on day 7 [total protein (g/L): 63.05±5.79 vs. 59.02±6.63, albumin (g/L): 40.40±5.26 vs. 37.66±4.63, hemoglobin (g/L): 133.33±12.58 vs. 123.80±22.12, all P < 0.05]. In terms of gastrointestinal complications, the incidence of stress ulcer in the UEEN group within 14 days after admission was significantly lower than that in the EEN group [12.5% (4/32) vs. 31.3% (10/32), P < 0.05], but there was no statistically significant difference in feeding intolerance symptoms between the two groups. In terms of neurological recovery and long-term prognosis, GCS scores and Barthel index scores of 14 days after admission were higher than those of 1 day after admission, but there was no statistical significance between the two groups. Six months after surgery, Glasgow outcome scale (GOS) and Barthel index score of the UEEN group were significantly higher than those of the EEN group (GOS score: 3.81±1.06 vs. 3.18±1.07, Barthel index score: 60.78±7.24 vs. 54.52±5.13, both P < 0.05). UEEN support can improve the nutritional level of young and middle-aged postoperative patients with cerebral hemorrhage, reduce the occurrence of postoperative gastrointestinal complications, promote the recovery of neurological function, and improve the long-term prognosis.

Relationship between abdominal fat volume and bone base material pairs from dual-energy spectral computed tomography in young and middle-aged patients with metabolic syndrome.

Metabolic syndrome (MetS) has complex effects on bone health, and dual-energy spectral computed tomography (CT) has become increasingly valuable for bone quantification. However, the relationship between bone base material pairs (BMPs) and abdominal fat volume in patients with MetS remains underexplored. This study thus aimed to analyze the relationship between abdominal fat volume and various bone BMPs using dual-energy spectral CT in young and middle-aged patients with MetS. Patients with MetS who underwent sleeve gastrectomy at the Center of Obesity and Metabolic Diseases, Beijing Shijitan Hospital, Capital Medical University, from June to November 2021 were retrospectively collected. The abdominal fat measurements and BMPs were acquired using dual-energy spectral CT imaging. These included the volumes of total abdominal fat (TAF), abdominal visceral fat (AVF), and abdominal subcutaneous fat (ASF), as well as bone densities based on hydroxyapatite (water), i.e., HAP (water), and calcium (water), i.e., Ca (water), BMPs. After grouping the patients by sex, we analyzed the differences in clinical and imaging features. The correlation between the clinical and imaging parameters of patients with MetS was evaluated with Pearson correlation coefficients. Age- and sex-adjusted partial correlation analysis between fat volume and bone BMPs was conducted for patients of different sexes. Additionally, multiple linear regression analyses were performed with age, sex, and TAF volume as the independent variables and with Ca (water) and HAP (water) as dependent variables. A total of 112 young and middle-aged patients with MetS were included in this study, including 85 females and 27 males. Compared to male patients with MetS, the females with MetS exhibited higher lumbar Ca (water) and HAP (water) BMPs, with lower volumes of TAF and AVF and a smaller abdominal circumference (P<0.01). The volumes of TAF, AVF, and ASF were negatively correlated with the average Ca (water) and HAP (water) BMPs in the first to third lumbar vertebrae (L1-L3) (P<0.05). Ca (water) and HAP (water) BMPs decreased with age and increasing TAF volume (P<0.001). The fitted equations for the relationship between bone BMPs with age, sex, and TAF volume were as follows: (I) bone Ca (water) BMP = 76.469 - 0.500 age + 6.762 sex - 0.002 TAF volume; (II) bone HAP (water) BMP =171.704 - 1.138 age + 11.825 sex - 0.004 TAF volume. In young and middle-aged patients with MetS, the abdominal fat volume was negatively correlated with lumbar bone Ca (water) and HAP (water) BMPs, implying that increased abdominal fat volume may play a crucial role in the pathogenesis of osteopenia among those with MetS. The reduction of bone Ca (water) and HAP (water) with high abdominal fat volume may hold clinical significance for fracture risk in individuals with MetS.

Abstract P313: Diastolic to Systolic Arterial stiffening has Greater Prognostic Power than Diastolic Stiffness in 20-60 Years Old Patients Undergoing 24-Hour Ambulatory Blood Pressure Monitoring

The 24-hour ambulatory pulse pressure (PP), can be expressed as a sum of two ‘PP components’: ‘elastic’ PP (elPP) and ‘stiffening’ PP (stPP) associated, respectively, with arterial stiffness at the diastolic pressure (somewhat equivalent to pulse wave velocity being measured in the diastole), and the relative stiffness change from the diastolic- to the systolic pressure. Here we assess and compare the hazard ratio (HR) of elPP and stPP for outcomes in a large cohort of young and middle-age patients. We analyzed adequate quality 24h ambulatory blood pressure monitoring records from the Spanish Ambulatory Blood Pressure Registry. For standard deviation(SD), K=SD(SBP)/SD(DBP), elPP=PPxln(K)/(K-1) and stPP=PP-elPP. HRs were determined for age 20-40, 41-50, and 51-60 years, using Cox regression models applied to standardized elPP &amp; stPP (combined), adjusted for age, sex, BMI, smoking status, diabetes, dyslipidemia, mean DBP, pulse rate, SD(SBP), antihypertensive treatment, and previous cardiovascular disease (CVD). The endpoints were total mortality, and death from CVD, or coronary heart disease (CHD). Of the 24,260 patients mean age (SD) 48.0(9.0) years, 34% male] 845 deaths occurred during period of 9.6(2.2) years. The Table shows that mean elPP slightly decreased from younger to older age, while stPP strongly increased. At age 41-60 years the adjusted HRs of stPP appeared significant and greater than those of elPP for almost all cases. The most contributing adjustors in the Cox regression were smoking, for all age classes, and sex for age over 40 years. Thus, the stiffening component may have greater predictive power than the elastic component for total mortality, and CVD&amp;CHD death, in middle-age patients.

Acupuncture for chronic nonspecific low back pain in middle-aged and older patients: A randomized controlled trial: 针刺治疗中老年慢性非特异性下腰痛:一项随机对照临床试验

ObjectiveTo observe the specific effects of acupuncture in middle-aged and older patients with chronic nonspecific low back pain (CNSLBP). MethodsSixty-six patients with CNSLBP were randomized into the acupuncture or sham acupuncture groups (n = 33). In the acupuncture group, penetrating acupuncture with a long needle was delivered at Ashi points (painful/sensitive points), and the needles were manipulated by rotating technique after deqi till patients felt distending pain. The needles were retained in place for 30 min. Acupuncture was given three times per week for 4 weeks. In the sham acupuncture group, shallow needling was performed at non-meridian, non-acupoint, non-painful, and non-sensitive points. The needle retention and duration of treatment were the same as those of the acupuncture group before treatment, after the first intervention, after the whole treatment, and in follow-up visit (4 weeks after the whole treatment). The scores of the visual analog scale(VAS) for pain, range of movement (ROM) of the spine, and simplified Oswestry Dysfunction Index (ODI) were observed separately. ResultsCompared to the outcomes before treatment, the VAS score, spinal ROM, and simplified ODI score were lower after the first intervention, after treatment, and in follow-up visits in the acupuncture group, indicating the statistical significance (P < 0.05). When compared with the sham acupuncture group, the VAS score, spinal ROM, and simplified ODI score were significantly lower in the acupuncture group after the first intervention, after treatment, and in follow-up visit (P < 0.05). The total effective rate was 90.9% in the acupuncture group, which was significantly higher than that (75.76 %) in the sham acupuncture group (P < 0.05). ConclusionAcupuncture has a specific effect on CNSLBP in middle-aged and older patients and a superior effect on immediate analgesia.

Determinants and prediction of hypertension among Chinese middle-aged and elderly adults with diabetes: A machine learning approach

ObjectiveMultimorbidity, particularly diabetes combined with hypertension (DCH), is a significant public health concern. Currently, there is a gap in research utilizing machine learning (ML) algorithms to predict hypertension risk in Chinese middle-aged and elderly diabetic patients, and gender differences in DCH comorbidity patterns remain unclear. We aimed to use ML algorithms to predict DCH and identify its determinants among middle-aged and elderly diabetic patients in China. Study designCross-sectional study. MethodsData were collected on 2775 adults with diabetes aged ≥45 years from the 2015 China Health and Retirement Longitudinal Study. We employed nine ML algorithms to develop prediction models for DCH. The performance of these models was evaluated using the area under the curve (AUC). Additionally, we conducted variable importance analysis to identify key determinants. ResultsOur results showed that the best prediction models for the overall population, men, and women were extreme gradient boosting (AUC = 0.728), light gradient boosting machine (AUC = 0.734), and random forest (AUC = 0.737), respectively. Age, waist circumference, body mass index, creatinine level, triglycerides, taking Western medicine, high-density lipoprotein cholesterol, blood urea nitrogen, total cholesterol, low-density lipoprotein cholesterol, and sleep disorders were identified as common important predictors by all three populations. ConclusionsML algorithms showed accurate predictive capabilities for DCH. Overall, non-linear ML models outperformed traditional logistic regression for predicting DCH. DCH predictions exhibited variations in predictors and model accuracy by gender. These findings could help identify DCH early and inform the development of personalized intervention strategies.

Precise Nursing Service Mode: The Golden Technique on Health Condition and Body Image among Middle-Aged and Elderly Patients with Prostate Cancer

Whether coagulation dysfunction influences the onset and progression of diabetic peripheral neuropathy: A multicenter study in middle-aged and aged patients with type 2 diabetes.

Nearly half of patients with diabetes experience diabetic peripheral neuropathy (DPN), resulting in a mere 53% survival rate within 3 years. Aberrations in coagulation function have been implicated in the pathogenesis of microvascular complications, prompting the need for a thorough investigation into its role as a contributing factor in the development and progression of DPN. Data were gathered from 1211 type 2 diabetes patients admitted to five centers from September 2018 to October 2022 in China. DPN was evaluated by symptoms and electromyography. Motor and sensory nerve conduction velocity (NCV) was appraised and the NCV sum score was calculated for the median, ulnar, and peroneal motor or sensory nerves. Patients with DPN exhibited alterations in coagulation function. (i) Specifically, they exhibited prolonged thrombin time (p = 0.012), elevated fibrinogen (p < 0.001), and shortened activated partial thromboplastin time (APTT; p = 0.026) when compared to the control group. (ii) After accounting for potential confounders in linear regression, fibrinogen, and D-dimer were negatively related to the motor NCV, motor amplitude values, and mean velocity and amplitude. Also, fibrinogen was associated with higher Michigan neuropathy screening instrument (MNSI) scores (β 0.140; p = 0.001). This result of fibrinogen can be validated in the validation cohort with 317 diabetic patients. (iii) Fibrinogen was independently associated with the risk of DPN (OR 1.172; p = 0.035). In the total age group, DPN occurred at a slower rate until the predicted fibrinogen level reached around 3.75 g/L, after which the risk sharply escalated. Coagulation function is warranted to be concerned in patients with type 2 diabetes to predict and prevent the occurrence of DPN in clinical practice.

Effect of Shi-Style Steaming and Bathing Decoction in Patients with Knee Osteoarthritis: Study Protocol for a Randomized Placebo-Controlled Trial.

To prove more accurately that Chinese herbal bath therapy may be a safe, effective, simple alternative treatment modality for knee OA, we designed a randomized, double-blind, placebo-controlled trial to explore the effectiveness of SSBD for the relief of pain, daily activities, and quality of life in patients with knee OA. A single-center, 52-week, randomized controlled trial of SSBD versus placebo is being performed. A total of 200 patients with symptomatic knee OA will be randomly allocated to the SSBD treatment or placebo intervention group for 4 weeks. The two groups of patients are allowed to steam and bathe their knees once every other day, using one packet of SSBD each time, for 30 minutes, 3 times a week, for a total of 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale at 4 weeks is the primary outcome measure, and the secondary outcomes include WOMAC stiffness and function scores, the Lysholm knee scale score, quality of life, the Brief Pain Inventory score, the Patient's Global Impressions of Improvement Scale score and the Clinical Global Impressions of Severity scale score. The safety of the herbal medications will also be evaluated. We will discuss whether SSBD has greater advantages in terms of efficacy, safety, and patient overall perception than does placebo control in middle-aged and elderly patients with knee OA. The findings may provide new and valuable information about the efficacy and safety of Chinese herbal bath therapy in the treatment of knee osteoarthritis.

Stroke knowledge level among patients with ischemic stroke at Universiti Malaya Medical Centre

Background and Objectives: Stroke is a significant public health concern. The rising trend among stroke survivors, middle-aged, and multi-comorbid patients highlights the need for preventive intervention. In Malaysia, stroke survivors had insufficient understanding of stroke, despite being a common illness in the country. Methods: A single-centre prospective study was conducted to determine the level of knowledge of stroke, its warning signs and symptoms, risk factors, and its association among stroke survivors who received treatment at the Universiti Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia. A validated Stroke Knowledge Test (SKT) questionnaire was used to analyse stroke knowledge. Results: The participant’s mean age was 57.79 (± 11.13) years old, with the majority being first-time stroke patients (87.2%), below 60 years of age (55.3%), had multiple comorbidities (93.4%), and male gender (68.1%). Most (71.4%) were non-adherent to their current medications. The study participants scored poorly on identifying warning signs compared to their knowledge of strokes in general and understanding of stroke risk factors. The majority have poor knowledge of smoking (1.8%) and atrial fibrillation (AF) (1.5%) as risk factors. However, there was good knowledge of the purpose of rehabilitation (98.9%). Conclusions: Participants’ knowledge about stroke, warning signs, symptoms, and risk factors were insufficient. Stroke knowledge was significantly associated with education, medication adherence, habitation, and income.

Biologics in rotator cuff repair.

Rotator cuff tears are common in middle-aged and elderly patients. Despite advances in the surgical repair of rotator cuff tears, the rates of recurrent tear remain high. This may be due to the complexity of the tendons of the rotator cuff, which contributes to an inherently hostile healing environment. During the past 20 years, there has been an increased interest in the use of biologics to complement the healing environment in the shoulder, in order to improve rotator cuff healing and reduce the rate of recurrent tears. The aim of this review is to provide a summary of the current evidence for the use of forms of biological augmentation when repairing rotator cuff tears.

Proxy consultations for severe mental illnesses: An exploratory cross-sectional study from a tertiary care hospital.

Non-adherence to medication leading to a break in continuity of care poses significant challenges in severe mental illness (SMI), leading to poor outcomes. In India, proxy consultation, wherein caregivers consult on behalf of patients, is a commonly adopted but insufficiently researched area to address these challenges. To explore the extent of proxy consultation in outpatient care of persons with SMI and investigate its sociodemographic and clinical correlates. In a tertiary care psychiatry outpatient setting, we conducted a cross-sectional study involving 374 caregivers of persons with SMI (Schizophrenia, Bipolar and related disorders). Descriptive statistics and univariate logistic regression were performed to examine correlates' relationships with proxy consultation. Proxy consultation prevalence was 43% in the past 1 year. Compared with 18 to 30 years, middle-aged patients aged 31 to 40, 41 to 50 and 51 to 60 years had twofold, threefold and sixfold increased chances of proxy consultation, respectively. Being illiterate had six times higher odds than graduates, three times and two times if they studied till primary and secondary education. Early age of onset was associated with three times higher chances of proxy consultation compared to the onset of illness in adulthood. On the contrary, male gender and upper and middle socioeconomic status decreased the chances of proxy consultation by 40%. Financial difficulties (n = 72, 45%) and patients' unwillingness to visit outpatients (n = 44, 27.5%) were the most commonly cited reasons for proxy consultation. Proxy consultations are relatively common, driven by many social, economic, patient-related, pragmatic and practical factors. In formulating community care policies for persons with SMI, the primary imperative should be to conduct additional research, deepening our understanding of proxy consultations. Additionally, it is essential to be mindful of the diverse issues associated with proxy consultations during the formulation process.

Prospective Assessment of Outcomes After Femoral Condyle Osteochondral Allograft Transplantation With Concurrent Meniscus Allograft Transplantation.

Osteochondral allograft transplantation (OCAT) and meniscus allograft transplantation (MAT) have each become more commonly implemented for the treatment of young to middle-aged patients with complex knee pathology. Evidence regarding tibiofemoral OCAT in the setting of concurrent MAT is limited. The purpose of this study was to characterize outcomes for femoral condyle OCAT with concurrent MAT (OCAT+MAT) in the ipsilateral compartment of patients after evidence-based shifts in practice. It was hypothesized that OCAT+MAT would be associated with successful outcomes characterized by statistically significant and clinically meaningful improvements in patient-reported outcome measures (PROMs) of knee pain and function in >80% of patients for at least 2 years after transplantation. Case series; Level of evidence, 4. With institutional review board approval and documented informed consent, patients who underwent primary OCAT+MAT between 2016 and 2020 and enrolled in a lifelong registry for prospective collection of outcomes after OCAT were included. Patients with minimum 2-year follow-up data regarding complications, failures, adherence, and PROMs were analyzed. Patients who required OCAT and/or MAT revision or conversion to arthroplasty were defined as experiencing treatment failures. A total of 23 consecutive patients (mean age, 37.1 years; mean body mass index, 28 kg/m2; 14 men) met the inclusion criteria, with a mean follow-up of 51 months (range, 24-86 months). The initial treatment success rate was 78% based on 5 initial treatment failures, and the overall success rate was 83% based on a successful revision OCAT. All failures occurred in the medial compartment. Older patient age (42.2 vs 32.1 years; P = .046) and nonadherence to postoperative restriction and rehabilitation protocols (P = .033; odds ratio, 14) were significant risk factors for treatment failure. All measured PROMs achieved significant improvements (P < .001) and minimum clinically important differences at a minimum of 2 years postoperatively. OCAT+MAT was associated with successful short- to mid-term outcomes in 83% of cases. Evidence-based shifts in practice were implemented before the enrollment of this patient cohort. Older patients and those who were not adherent to postoperative restriction and rehabilitation protocols had a significantly higher risk for treatment failure and subsequent conversion to arthroplasty.

Preventing postoperative moderate- and high-risk pressure injuries with artificial intelligence-powered smart decompression mattress on in middle-aged and elderly patients: a retrospective cohort analysis.

Aims/Background Artificial intelligence technology has attained rapid development in recent years. The integration of artificial intelligence applications into pressure reduction mattresses, giving rise to artificial intelligence-powered pressure reduction mattresses, is expected to provide personalised intelligent pressure reduction solutions, through automatic user's data-based adjustment of the patient's local pressure condition to prevent pressure injury. The purpose of this study was to investigate the effectiveness of artificial intelligence-powered smart decompression in the prevention of postoperative medium- and high-risk pressure injury in middle-aged and elderly patients. Methods A total of 400 middle-aged and elderly patients admitted to our hospital from June 2021 to December 2023 were selected as study subjects. Patients were categorised into observation and control groups according to the medical record system. General demographic data of the patients were collected. The propensity score matching method was used to balance the baseline data of the two groups of patients. The incidence, severity, complications and sleep quality in the matched study subjects were also compared. Results After matching, there were 96 patients in the two groups, and the differences in baseline data between the two groups were not statistically significant. Pressure injury and the total incidence of complications in the observation group were significantly lower than those in the control group (p < 0.05). Before treatment, there was no difference in the scores of all aspects of the Richards Campbell Sleep Questionnaire between the two groups (p > 0.05). After treatment, the scores of all aspects of Richards Campbell Sleep Questionnaire in the observation group were significantly lower than those in the control group (p < 0.05). Conclusion The artificial intelligence-powered smart decompression mattress can significantly prevent moderate- and high-risk pressure injury, effectively reducing the incidence of pressure injury and complications in postoperative long-term bedridden patients, alleviating the severity of pressure injury, relieving the pressure on various parts, and improving the sleep quality of patients.
