DNA methylation is involved in the pathogenesis and prognosis of stroke. However, the effect of DNA methylation on stroke at high levels of inflammation is unclear. In this study, we constructed a hyperinflammatory cerebral ischemia mouse model and investigated the effect of hypomethylation and hypermethylation on the functional outcome. We constructed a mouse model of transient middle cerebral artery occlusion and treated the mice with lipopolysaccharide to induce a hyperinflammatory state. To investigate the effect of DNA methylation on stroke, we used small molecule inhibitors to restrain the function of key DNA methylation and demethylation enzymes. 2,3,5-Triphenyltetrazolium chloride staining, neurological function scores, neurobehavioral tests, enzyme-linked immunosorbent assay, quantitative reverse transcription PCR and western blot assay were used to evaluate the effects after stroke in mice. We assessed changes in the global methylation status by measuring DNA 5-mc and DNA 5-hmc levels in peripheral blood after the use of the inhibitor. In the group treated with the DNA methylation inhibitor, brain tissue 2,3,5-triphenyltetrazolium chloride staining showed an increase in infarct volume, which was accompanied by a decrease in neurological scores and worsening of neurobehavioral performance. The levels of inflammatory factors interleukin 6 and interleukin-1 beta in ischemic brain tissue and plasma were elevated, indicating increased inflammation. Related inflammatory pathway exploration showed significant overactivation of nuclear factor kappa B. These results suggested that inhibiting DNA methylation led to poor functional outcome in mice with high inflammation following stroke. Further, the effects were reversed by inhibition of DNA demethylation. Our findings suggest that DNA methylation regulates the inflammatory response in stroke and has an important role in the functional outcome of hyperinflammatory stroke.展开更多

The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.展开更多

METHODS: Consecutive patients hospitalized for acute ischemic stroke between September 2010 and June 2013 were studied prospectively(n = 482; 40.2% males, age 78.8 ± 6.7 years). T2 DM was defined as self-reported T2 DM or antidiabetic treatment. Stroke severity was evaluated with the National Institutes of Health Stroke Scale(NIHSS) score at admission. The outcome was assessed with the modified Rankin scale(m RS) score at discharge and with in-hospital mortality. Adverse outcome was defined as m RS score at discharge ≥ 2 or in-hospital death. The length of hospitalization was also recorded.RESULTS: T2 DM was present in 32.2% of the study population. Patients with T2 DM had a larger waist circumference, higher serum triglyceride and glucose levels and lower serum high-density lipoprotein cholesterol levels as well as higher prevalence of hypertension, coronary heart disease and congestive heart failure than patients without T2 DM. On the other hand, diabetic patients had lower low-density lipoprotein cholesterol levels and reported smaller consumption of alcohol than non-diabetic patients. At admission, the NIHSS score did not differ between patients with and without T2DM(8.7 ± 8.8 and 8.6 ± 9.2, respectively; P = NS). At discharge, the m RS score also did not differ between the two groups(2.7 ± 2.1 and 2.7 ± 2.2 in patients with and without T2 DM, respectively; P = NS). Rates of adverse outcome were also similar in patients with and without T2DM(62.3% and 58.5%, respectively; P = NS). However, when we adjusted for the differences between patients with T2 DM and those without T2 DM in cardiovascular risk factors, T2 DM was independently associated with adverse outcome [relative risk(RR) = 2.39; 95%CI: 1.21-4.72, P = 0.012]. Inhospital mortality rates did not differ between patients with T2 DM and those without T2DM(9.0% and 9.8%, respectively; P = NS). In multivariate analysis adjusting for the difference in cardiovascular risk factors between the two groups, T2 DM was again not associated with in-hospital death. CONCLUSION: T2 DM does not appear to affect ischemic stroke severity but is independently associated with a worse functional outcome at discharge.展开更多

Methods A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ≥ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage. Results The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of 〈 30 U/L, 30-50 U/L and ≥ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively （P 〈 0.01）. The age-sex and multivariable adjusted odds ratios （95% confidence intervals） of poor prognosis comparing the top group （≥ 50 U/L） with the lowest group （〈 30 U/L） were 5.76 （2.74-12.13）, 6.64 （2.05-21.52）, and 6.36 （1.92-21.02）. A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers. Conclusion Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.展开更多

Decompressive Hemicraniectomy has been utilized to treat brain swelling and mass effect secondary to these infarctions in an attempt to improve functional outcome. <strong>Aim: </strong>To evaluate the functional outcome of decompressive hemicraniectomy in management of malignant MCA infarctions. <strong>Methods: </strong>The study included 30 patients with malignant MCA infarctions operated upon by decompressive hemicraniectomy and duroplasty with pericranium or fascia lata graft in the period from June 2016 to January 2019. Pre-operative neurological condition, associated morbidity, location and extent of the infarction were assessed. Surgery was performed within 48 hours of the onset of stroke or 12 hours within deterioration of conscious level. Pre-operative CT scan as well as sequential post-operative CT was done. Functional outcome was assessed by the modified Rankin Scale (mRS) at the time of discharge and 3 months following surgery. <strong>Results: </strong>The study included 18 males and 12 females with a mean age of 54.7 years. The pre-operative GCS was <8 (5 - 7) in 11 patients and 8 or higher (8 - 13) in 19 patients. Good functional outcome (mRS 0 - 3) was achieved in 13 (43.3%) cases while poor outcome (mRS 4 - 5) occurred in 8 (26.7%) cases and mortality (mRS 6) occurred in 9 (30%) cases. <strong>Conclusion:</strong> Decompressive hemicraniectomy improves functional outcome in cases of malignant MCA infarction. Pre-operative GCS, age, volume of infarction, degree of midline shift, timing of surgery and associated morbidity are the most important factors affecting the outcome.展开更多

Differ...Background: Stroke survivors who exhibit impaired cognition at admission to inpatient rehabilitation may experience participation challenges and poorer functional outcomes than those without impaired cognition. Differences in functional outcomes between stroke survivors with and without impaired cognition may be attributed to age, level of cognitive impairment, and severity of stroke. Materials and Methods: A retrospective secondary data analysis was conducted using health-related administrative data acquired from a Southwestern Ontario hospital’s stroke rehabilitation database. The aim was to explore potential linkages between post-stroke impaired cognition and functional gains, rehabilitation stays, and living settings after discharge from rehabilitation. Results: An aggregate sample of 393 males and 314 females subclassified as experiencing mild, moderate, and severe stroke was analyzed. At inpatient rehabilitation admission, 21.5% (n = 152) of these patients had no impaired cognition, 33.7% (n = 238) had mild impaired cognition, 22.2% (n = 157) had moderate impaired cognition, and 22.6% (n = 160) had severe impaired cognition. Cognitively impaired stroke patients were significantly (p 0.001) older, had (mostly) moderate to severe stroke with significantly (p = 0.012) more moderate cognitive impairment, had significantly (p 0.001) longer rehabilitation stays, and a high propensity for being discharged to longer-term care facilities compared to non-cognitively impaired patients. Conclusion: Presence of significant dissimilarity in rehabilitation stays and post-discharge destinations among stroke survivors with and without cognitive impairment is attributed to the age of the patient, level of cognitive impairment, and rigorous rehabilitation interventions.展开更多

The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square ort-test.Results:During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (allp > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients.Conclusion:Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.展开更多

Patients had neovascular AMD and were initially treated with intravitreal ranibizumab （0.5 mg） between November 1, 2007 and October 31, 2008, had （6y of data available, and were treated on an ongoing, as-needed basis. Outcomes included best-corrected visual acuity （BCVA） and central retinal thickness （CRT）.RESULTS： The sample consisted of 88 eyes from 69 patients. Mean age was 76.4±6.5y, most patients were female （62.3%）. Most eyes （62.5%） were treatment-naive, 33 previously treated eyes had received predominantly other anti-vascular endothelial growth factor agents and verteporfin. Mean baseline BCVA was 57.4±12.7 ETDRS letters and CRT was 291.5±86.1 （m. On average, patients received 20.6±11.9 ranibizumab injections over the （6y. Intervals between injections were on average 12.7±16.1wk. Mean change in BCVA from baseline to last observation for the sample was less than one letter （-0.9±17.3 letters）, with an average loss of -3.2±15.6 letters in previously treated eyes versus a gain of 0.6±18.4 letters in treatment-na？ve eyes. When considering a loss of 〈15 letters over 6y as stabilization of disease, 75.9% of all eyes showed a positive （improvement or stabilization） outcome. Mean change in CRT from baseline to last observation for the sample was -26.9±148.4 （m with the greatest reduction observed in treatment-naive eyes.CONCLUSION： This retrospective study of 69 neovascular AMD patients treated for （6y with ranibizumab demonstrates long-term visual stabilization. In light of the natural evolution of the disease, these data confirm that ranibizumab is effective long-term under real-world conditions of heterogeneity of patients, clinicians, and centers.展开更多

文摘BACKGROUND The posterior cruciate ligament(PCL)is vital for regulating posterior tibial translation in relation to the femur,which is critical for knee stability.PCL tears are infrequently isolated in knee injuries;however,the absence of the PCL results in abnormal knee kinematics,which may cause injuries to other ligaments.The ideal tendon source for PCL reconstruction is still a subject of debate.AIM To evaluate the results of employing the peroneus longus tendon(PLT)in PCL reconstruction.METHODS A comprehensive search was conducted to identify relevant randomized controlled trials and retrospective observational studies discussing the outcomes of using the PLT for PCL reconstruction.Studies published up to August 2024 were searched across multiple databases,including PubMed,EMBASE,Scopus,Web of Science,Cochrane Library,and Google Scholar.Full texts of the selected articles were retrieved,reviewed,and independently assessed by the investigators.Discrepancies were resolved by consensus,with any remaining disagreements being arbitrated by a third author.RESULTS This meta-analysis included five studies on PLT use for PCL reconstruction:(1)Four prospective studies with 104 patients;and(2)One retrospective study with 18 patients.Most studies followed up participants for 24 months,while one had a shorter follow-up of 18 months.Lysholm and modified cincinnati scores improved by pooled means of 32.2(95%CI:29.3-35.1,I2=0%)and 31.1(95%CI:27.98-34.22,I2=0%),respectively.Postoperative American Orthopaedic Foot and Ankle Society and Foot and Ankle Disability Index scores were 94.5(I2=61.5%)and 94.5(I2=80.09%),respectively.Single-hop and triple-hop test scores averaged 95.5(95%CI:94.5-96.5)and 92.4(95%CI:91.9-92.9)respectively.No significant differences were observed in thigh circumference at 10 cm and 20 cm between the injured and healthy sides.CONCLUSION Evidence supports PLT autografts for PCL reconstruction,improving knee function and patient outcomes.Larger randomized trials are needed to confirm efficacy and compare graft options.
文摘BACKGROUND Total knee arthroplasty(TKA)is a widely used treatment for advanced knee osteoarthritis;however,the incidence of failures requiring revision surgery is increasing.Identifying the causes of TKA failure and assessing the outcomes of revision procedures are essential for improving patient care.We hypothesized that infection and aseptic loosening are the primary causes of TKA failure and that revision TKA(rTKA)significantly enhances functional outcomes.AIM To examine the primary causes of TKA failure and evaluate the functional outcomes following rTKA.METHODS This descriptive study was conducted at the Department of Orthopedic Surgery,Civil Hospital,Bahawalpur,from April to September 2024.A total of 118 patients undergoing rTKA for failed primary TKA were included.Data on demographics,causes of failure,and surgical details were collected.Functional outcomes were evaluated using the Knee Society Score and Visual Analog Scale before and six months after surgery.Statistical analysis was performed using SPSS version 25.0,with statistical significance set at P<0.05.RESULTS The leading causes of TKA failure were infection(45.8%),aseptic loosening(44.1%),and periprosthetic fractures(10.2%).The rTKA significantly improved knee function,with the mean Knee Society Score increasing from 39.43±6.18 to 78.91±6.17(P<0.001).Pain levels decreased substantially,with the mean Visual Analog Scale scores reducing from 7.99±1.37 to 1.42±1.17(P<0.001).No significant differences in outcomes were observed between single-stage and two-stage revision procedures.CONCLUSION Infection and aseptic loosening are the predominant causes of TKA failure.The rTKA effectively enhances knee function and alleviates pain,offering significant benefits to patients.
文摘BACKGROUND Radial head fractures constitute approximately one-third of all elbow fractures,significantly impacting the young and active population.While open reduction and internal fixation is the preferred treatment for displaced fractures,its high complication rate in comminuted fractures has led to the increasing use of radial head arthroplasty(RHA).RHA provides improved functional outcomes with fewer complications,yet its long-term efficacy remains a topic of debate.AIM To evaluate the functional outcomes of patients undergoing RHA with a modular metallic prosthesis for comminuted Mason type III and IV radial head fractures.METHODS A prospective and retrospective hospital-based study was conducted at Dayanand Medical College and Hospital,Ludhiana over 32 months(January 2021-August 2023).A total of 26 patients with Mason type III and IV fractures were included,with six retrospective and 20 prospective cases.Functional outcomes were assessed using the Mayo Elbow Performance Score(MEPS),elbow range of motion,pain via Visual Analog Scale,and activities of daily living at immediate postoperative,three-month,and six-month follow-ups.RESULTS MEPS at 6 months follow up for 4 cases(15.38%)had good scores,and 22 cases(84.62%)had excellent scores,with a mean±SD of 97.31±6.67.Comparisons showed significant improvement from immediate post-operative to 3 months(P<0.0001),from immediate post-operative to 6 months(P<0.0001),and between 3 months and 6 months(P<0.0001).None of the patients had elbow instability after radial head replacement and 22 cases(84.62%)had no complications,while 3 cases(11.54%)had a stiff elbow,and 1 case(3.85%)had heterotopic ossification.CONCLUSION RHA is an effective treatment for comminuted radial head fractures,providing stable elbow function with minimal complications.

文摘Inflammation is closely related to stroke prognosis, and high inflammation status leads to poor functional outcome in stroke. DNA methylation is involved in the pathogenesis and prognosis of stroke. However, the effect of DNA methylation on stroke at high levels of inflammation is unclear. In this study, we constructed a hyperinflammatory cerebral ischemia mouse model and investigated the effect of hypomethylation and hypermethylation on the functional outcome. We constructed a mouse model of transient middle cerebral artery occlusion and treated the mice with lipopolysaccharide to induce a hyperinflammatory state. To investigate the effect of DNA methylation on stroke, we used small molecule inhibitors to restrain the function of key DNA methylation and demethylation enzymes. 2,3,5-Triphenyltetrazolium chloride staining, neurological function scores, neurobehavioral tests, enzyme-linked immunosorbent assay, quantitative reverse transcription PCR and western blot assay were used to evaluate the effects after stroke in mice. We assessed changes in the global methylation status by measuring DNA 5-mc and DNA 5-hmc levels in peripheral blood after the use of the inhibitor. In the group treated with the DNA methylation inhibitor, brain tissue 2,3,5-triphenyltetrazolium chloride staining showed an increase in infarct volume, which was accompanied by a decrease in neurological scores and worsening of neurobehavioral performance. The levels of inflammatory factors interleukin 6 and interleukin-1 beta in ischemic brain tissue and plasma were elevated, indicating increased inflammation. Related inflammatory pathway exploration showed significant overactivation of nuclear factor kappa B. These results suggested that inhibiting DNA methylation led to poor functional outcome in mice with high inflammation following stroke. Further, the effects were reversed by inhibition of DNA demethylation. Our findings suggest that DNA methylation regulates the inflammatory response in stroke and has an important role in the functional outcome of hyperinflammatory stroke.
文摘Objective: Radical cystectomy(RC)is a standard treatment for localized muscle invasive bladder cancer and high-risk or very high-risk non-muscle invasive bladder cancer not responding to adequate endovesical therapy.In women,traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall,often resulting in sexual disorders.Vaginal-sparing techniques have been developed to improve functional outcomes.The present study explores the safety and the functional outcome of vaginal-sparing techniques.Methods: We retrospectively analyzed all consecutive female patients undergoing robot-assisted RC(RARC)with neobladder diversion between October 2017 and February 2022.The indications for vaginal-sparing RC were absence of tumor on bladder neck or urethra and no sign of infiltration of posterior bladder wall at the preoperative MRI.Functional results were evaluated with the aid of five questions out of the Bladder Cancer Index questionnaire.Complications were reported according to the Clavien–Dindo classification and cancer control was evaluated by recurrence-free and cancer-specific survival.Results: A total of 22 female patients underwent RARC with neobladder diversion.Neoadjuvant chemotherapy was given in 17(77%)cases.Clavien–Dindo grades III–IV complications occurred in four(18%)cases.After a mean follow-up of 29(interquartile range 16–44)months,six(27.3%)patients developed distant metastases,and one(4.5%)woman loco-regional relapse.Sexual-sparing surgery was performed in 19(86%)patients,and in the others the anterior vaginal wall was resected,but neobladder was still performed.During daytime,no patients reported total incontinence and 73%(11/15)reported total continence or only occasional leaks.Sexual results showed that seven of 15(47%)women regained sexual activity after surgery,with a quality reported as“good”or“very good”in 40%of all 19 cases.Conclusion: RARC in female with anterior vaginal wall preservation is feasible.The approach showed a good safety profile,with satisfying results on continence and sexual activity.Sexual-sparing approaches should be carried out after correct patient selection.
文摘BACKGROUND Post-stroke depression(PSD)is a common and debilitating condition affecting stroke survivors,significantly impacting their recovery and overall quality of life.AIM To assess the effects of early PSD screening on functional outcomes,quality of life,and mortality.METHODS From an initial pool of 1065 articles,6 studies met the inclusion criteria and were selected for analysis.Functional outcomes were measured using the functional independence measure(FIM).RESULTS The analysis revealed a significant improvement in FIM scores for a PSD scree-ning group compared to controls[standardized mean difference(SMD)=8.90,95%confidence interval(CI):4.65-13.15,P<0.01].Quality of life was assessed using the Stroke-Specific Quality of Life Scale,with the screening group showing significantly higher scores(SMD=20.83,95%CI:15.27-26.38,P<0.01).Mortality analysis indicated a reduction in five-year mortality rates for the PSD screening group.CONCLUSION Early PSD screening enhances functional recovery,improves quality of life,and reduces mortality rates in stroke survivors.Thus,integrating PSD screening into routine stroke care improves long-term outcomes for patients.
文摘Introduction: The management of fractures of the tibia shaft is an important aspect of orthopaedic care, and the selection of the surgical method for fixation can substantially impact patient outcomes. The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.
文摘AIM: To assess whether ischemic stroke severity and outcome is more adverse in patients with type 2 diabetes mellitus(T2DM). METHODS: Consecutive patients hospitalized for acute ischemic stroke between September 2010 and June 2013 were studied prospectively(n = 482; 40.2% males, age 78.8 ± 6.7 years). T2 DM was defined as self-reported T2 DM or antidiabetic treatment. Stroke severity was evaluated with the National Institutes of Health Stroke Scale(NIHSS) score at admission. The outcome was assessed with the modified Rankin scale(m RS) score at discharge and with in-hospital mortality. Adverse outcome was defined as m RS score at discharge ≥ 2 or in-hospital death. The length of hospitalization was also recorded.RESULTS: T2 DM was present in 32.2% of the study population. Patients with T2 DM had a larger waist circumference, higher serum triglyceride and glucose levels and lower serum high-density lipoprotein cholesterol levels as well as higher prevalence of hypertension, coronary heart disease and congestive heart failure than patients without T2 DM. On the other hand, diabetic patients had lower low-density lipoprotein cholesterol levels and reported smaller consumption of alcohol than non-diabetic patients. At admission, the NIHSS score did not differ between patients with and without T2DM(8.7 ± 8.8 and 8.6 ± 9.2, respectively; P = NS). At discharge, the m RS score also did not differ between the two groups(2.7 ± 2.1 and 2.7 ± 2.2 in patients with and without T2 DM, respectively; P = NS). Rates of adverse outcome were also similar in patients with and without T2DM(62.3% and 58.5%, respectively; P = NS). However, when we adjusted for the differences between patients with T2 DM and those without T2 DM in cardiovascular risk factors, T2 DM was independently associated with adverse outcome [relative risk(RR) = 2.39; 95%CI: 1.21-4.72, P = 0.012]. Inhospital mortality rates did not differ between patients with T2 DM and those without T2DM(9.0% and 9.8%, respectively; P = NS). In multivariate analysis adjusting for the difference in cardiovascular risk factors between the two groups, T2 DM was again not associated with in-hospital death. CONCLUSION: T2 DM does not appear to affect ischemic stroke severity but is independently associated with a worse functional outcome at discharge.

文摘Objective We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population. Methods A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ≥ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage. Results The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of 〈 30 U/L, 30-50 U/L and ≥ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively （P 〈 0.01）. The age-sex and multivariable adjusted odds ratios （95% confidence intervals） of poor prognosis comparing the top group （≥ 50 U/L） with the lowest group （〈 30 U/L） were 5.76 （2.74-12.13）, 6.64 （2.05-21.52）, and 6.36 （1.92-21.02）. A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers. Conclusion Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.
文摘<strong>Introduction:</strong> Malignant middle cerebral artery (MCA) infarction is a devastating entity that is associated with up to 80% mortality. Decompressive Hemicraniectomy has been utilized to treat brain swelling and mass effect secondary to these infarctions in an attempt to improve functional outcome. <strong>Aim: </strong>To evaluate the functional outcome of decompressive hemicraniectomy in management of malignant MCA infarctions. <strong>Methods: </strong>The study included 30 patients with malignant MCA infarctions operated upon by decompressive hemicraniectomy and duroplasty with pericranium or fascia lata graft in the period from June 2016 to January 2019. Pre-operative neurological condition, associated morbidity, location and extent of the infarction were assessed. Surgery was performed within 48 hours of the onset of stroke or 12 hours within deterioration of conscious level. Pre-operative CT scan as well as sequential post-operative CT was done. Functional outcome was assessed by the modified Rankin Scale (mRS) at the time of discharge and 3 months following surgery. <strong>Results: </strong>The study included 18 males and 12 females with a mean age of 54.7 years. The pre-operative GCS was <8 (5 - 7) in 11 patients and 8 or higher (8 - 13) in 19 patients. Good functional outcome (mRS 0 - 3) was achieved in 13 (43.3%) cases while poor outcome (mRS 4 - 5) occurred in 8 (26.7%) cases and mortality (mRS 6) occurred in 9 (30%) cases. <strong>Conclusion:</strong> Decompressive hemicraniectomy improves functional outcome in cases of malignant MCA infarction. Pre-operative GCS, age, volume of infarction, degree of midline shift, timing of surgery and associated morbidity are the most important factors affecting the outcome.
文摘Giant cell tumor of the bone(GCTB)is a benign,locally aggressive neoplasm that is relatively rare,with a propensity to result in progressive bone destruction,and is associated with a high risk of recurrence.There is no widely held consensus regarding its ideal treatment.Worldwide,there are varying techniques ranging from intralesional curettage to resection of the lesion,supplemented with combinations of numerous adjuncts and fillers,depending on the resected amount and integrity of bone,as well as the preference of the surgeon.This was a cross-sectional study that included 20 patients who underwent limb salvage surgery for giant cell tumor of the bone of the lower extremities from January 2009 to February 2020 at two tertiary hospitals.The mean follow-up period was 37.3 months(SD=2.84).The extended curettage(EC)group had a mean Musculoskeletal Tumor Rating Scale(MSTS)score of 28.18(SD=7.51)which is considered as an excellent outcome,while the resection(RS)group had an mean MSTS score of 19.67(SD=11.02),which is considered as a good outcome.EC resulted to a total of eight complications(47%),while RS had one complication(33%).Prevalence of recurrence was noted to be 11.75%among those who underwent EC,while no recurrence was noted among those in the RS group.Use of bone cement as a filler was noted to have less recurrence as compared with the use of bone grafts,however were both were noted to result in excellent functional outcomes.Despite the prevalence of complications and recurrence of GCTB of the salvaged extremity in those who underwent EC,there is still report of excellent functionality.It is hence important to disclose all these possible outcomes and to stress the importance of compliance to follow-up for monitoring of these events.

文摘Background: Stroke survivors who exhibit impaired cognition at admission to inpatient rehabilitation may experience participation challenges and poorer functional outcomes than those without impaired cognition. Differences in functional outcomes between stroke survivors with and without impaired cognition may be attributed to age, level of cognitive impairment, and severity of stroke. Materials and Methods: A retrospective secondary data analysis was conducted using health-related administrative data acquired from a Southwestern Ontario hospital’s stroke rehabilitation database. The aim was to explore potential linkages between post-stroke impaired cognition and functional gains, rehabilitation stays, and living settings after discharge from rehabilitation. Results: An aggregate sample of 393 males and 314 females subclassified as experiencing mild, moderate, and severe stroke was analyzed. At inpatient rehabilitation admission, 21.5% (n = 152) of these patients had no impaired cognition, 33.7% (n = 238) had mild impaired cognition, 22.2% (n = 157) had moderate impaired cognition, and 22.6% (n = 160) had severe impaired cognition. Cognitively impaired stroke patients were significantly (p 0.001) older, had (mostly) moderate to severe stroke with significantly (p = 0.012) more moderate cognitive impairment, had significantly (p 0.001) longer rehabilitation stays, and a high propensity for being discharged to longer-term care facilities compared to non-cognitively impaired patients. Conclusion: Presence of significant dissimilarity in rehabilitation stays and post-discharge destinations among stroke survivors with and without cognitive impairment is attributed to the age of the patient, level of cognitive impairment, and rigorous rehabilitation interventions.

文摘BACKGROUND Hip fracture in elderly patients,particularly those with comorbid post-traumatic stress disorder(PTSD),presents a significant clinical challenge.In addition to the physiological stress of surgery,these patients often endure psychological burdens that may adversely affect postoperative recovery.The potential benefits of targeted perioperative psychological interventions have not been fully elucidated in this special population.This study hypothesized that a structured perioperative psychological program would improve recovery outcomes,including postoperative pain,functional outcomes,and mental well-being.AIM To evaluate the impact of perioperative psychological intervention on postoperative outcomes among elderly patients with PTSD undergoing hip fracture surgery.METHODS Between January 1,2022,and December 31,2024,medical records of 50 elderly hip fracture patients(age≥65)with PTSD who underwent surgical fixation at our center were retrospectively reviewed.Patients were divided into an intervention(n=25;standardized psychological care)and control(n=25;usual care)groups.Data collected included demographics,fracture type,PTSD severity,and anesthesia details.The intervention comprised preoperative counseling,relaxation training,and postoperative coping sessions.Postoperative outcomes compared included pain,PTSD severity,activities of daily living scores,complications,length of stay,mental health,and functional recovery.RESULTS The groups had comparable demographic and clinical characteristics.The intervention group demonstrated significantly lower pain scores on postoperative days 3 and 7(P<0.01),fewer moderate-to-severe depressive symptoms(P<0.05),and a greater reduction in PTSD severity(P<0.01)compared with the control group.Furthermore,the intervention group exhibited improved activities of daily living scores at 4 weeks post-surgery and a lower postoperative complication rate(16%vs 32%,P=0.14).The average length of hospital stay was shorter in the intervention group(11.5±2.0 days vs 13.1±2.6 days,P<0.05).CONCLUSION In elderly hip fractures patients with comorbid PTSD,perioperative psychological interventions improved pain control,functional recovery,and PTSD symptoms,supporting its value in holistic perioperative management and outcome enhancement.
文摘BACKGROUND Proximal humerus fractures(PHFs)are common,especially in the elderly,and optimal surgical management remains debated.This study compares clinical,functional,and radiographic outcomes of deltoid split(DS)vs deltopectoral(DP)approaches in PHFs treated with locking plates.AIM To evaluate and compare the clinical,functional,and radiographic outcomes-as well as postoperative complication rates-associated with the DS vs the DP surgical approach in the open reduction and internal fixation(ORIF)of PHFs using locking plate constructs.METHODS A multicenter retrospective study of 120 patients undergoing ORIF for closed Neer type II-IV PHFs between January 2023 and December 2023.Patients were grouped by surgical approach[DS(n=70),DP(n=50)].Outcome measures included Numeric Rating Scale(NRS)for pain,Quick-Disabilities in Arm,Shoulder,and Hand questionnaire(QuickDASH),Constant-Murley score,Short Form Health Survey-12v2,and radiographic alignment.Complication rates were recorded.Statistical significance was defined as P<0.05.RESULTS Early outcomes favored the DS group:(1)Lower NRS(3.1 vs 5.9);(2)Higher Constant-Murley(68.2 vs 50.5);and(3)Better QuickDASH(25.4 vs 37.1).Complication rate was lower in the DS group(1.66%vs 5.81%).Radiographic outcomes were comparable.Long-term results were similar between groups.CONCLUSION While both approaches yield satisfactory long-term outcomes,the DS approach is associated with faster early recovery and fewer complications,supporting its use in selected cases.
文摘BACKGROUND Unstable intertrochanteric fractures in elderly patients require effective surgical management,with both cementless bipolar hemiarthroplasty(CBHA)and proximal femoral nail anti-rotation(PFNA)being valid treatment options to reduce morbidity and mortality.AIM To evaluate and compare the outcomes of CBHA and PFNA in treatment of unstable intertrochanteric fractures.METHODS A comprehensive search was conducted to identify relevant studies discussing the outcomes of using both CBH and PFNA in treatment of unstable intertrochanteric fractures.Studies published up to January 1,2025 were searched across multiple databases,including PubMed,EMBASE,Scopus,Web of Science,Cochrane Library,and Google Scholar.Full texts of the selected articles were retrieved,reviewed,and independently assessed by the investigators.Discrepancies were resolved by consensus,with any remaining disagreements being arbitrated by a third author.RESULTS This meta-analysis included three studies,all of which were retrospective,involving a total of 240 patients.The follow-up period for participants was at least 12 months.CBHA was associated with significantly higher blood loss compared to PFNA[mean differences(MD):129.14,95%CI(52.51,205.77),P=0.001],though heterogeneity was high(I²=97%).Operative time showed no significant difference initially[MD:6.10,95%CI(-13.34,25.54),P=0.54],but after excluding one study,BHA had longer operative times[MD:21.51,95%CI(18.60,24.41),P<0.00001].Hospital stay and Harris scores showed no significant differences between groups.CBHA facilitated faster progression to weight-bearing[MD:-11.92,95%CI(-22.46,-1.39),P=0.03]and a lower incidence of prosthetic loosening[risk ratio:0.21,95%CI(0.05,0.92),P=0.04].Refracture and thrombus formation rates were comparable between the two groups.CONCLUSION CBHA offers shorter weight-bearing duration and reduced prosthetic loosening but incurs greater blood loss and longer operative times compared to PFNA.Both techniques show comparable functional recovery,hospital stay,refracture,and thrombus risks.Clinical choice should prioritize early mobilization or surgical minimalism,guided by patient needs.Further prospective studies are warranted.
文摘Purpose:To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures.Methods:A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square ort-test.Results:During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (allp > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients.Conclusion:Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.
文摘AIM： To evaluate the outcomes of （6y ranibizumab therapy in neovascular age-related macular degeneration （AMD）.METHODS： HELIX was a retrospective, observational effectiveness study using medical records of patients treated in three clinics in Belgium. Patients had neovascular AMD and were initially treated with intravitreal ranibizumab （0.5 mg） between November 1, 2007 and October 31, 2008, had （6y of data available, and were treated on an ongoing, as-needed basis. Outcomes included best-corrected visual acuity （BCVA） and central retinal thickness （CRT）.RESULTS： The sample consisted of 88 eyes from 69 patients. Mean age was 76.4±6.5y, most patients were female （62.3%）. Most eyes （62.5%） were treatment-naive, 33 previously treated eyes had received predominantly other anti-vascular endothelial growth factor agents and verteporfin. Mean baseline BCVA was 57.4±12.7 ETDRS letters and CRT was 291.5±86.1 （m. On average, patients received 20.6±11.9 ranibizumab injections over the （6y. Intervals between injections were on average 12.7±16.1wk. Mean change in BCVA from baseline to last observation for the sample was less than one letter （-0.9±17.3 letters）, with an average loss of -3.2±15.6 letters in previously treated eyes versus a gain of 0.6±18.4 letters in treatment-na？ve eyes. When considering a loss of 〈15 letters over 6y as stabilization of disease, 75.9% of all eyes showed a positive （improvement or stabilization） outcome. Mean change in CRT from baseline to last observation for the sample was -26.9±148.4 （m with the greatest reduction observed in treatment-naive eyes.CONCLUSION： This retrospective study of 69 neovascular AMD patients treated for （6y with ranibizumab demonstrates long-term visual stabilization. In light of the natural evolution of the disease, these data confirm that ranibizumab is effective long-term under real-world conditions of heterogeneity of patients, clinicians, and centers.
文摘BACKGROUND The morbidity and burden of knee osteoarthritis affecting millions of lives worldwide has created a constant pursuit in finding the ideal treatment for knee osteoarthritis.There has been a paradigm shift in the surgical treatment of osteoarthritis ever since the initial description of Volkmann’s tibial osteotomy.This review focuses on one such recent procedure,the proximal fibular osteotomy(PFO)for medial compartment knee osteoarthritis.This review encompasses the history,evidence,risk factors,outcomes and technical considerations of PFO.AIM To understand the evidence and its techniques,and whether this could be an alternative solution to the problem of knee osteoarthritis in the developing world.METHODS The phrases“proximal fibular osteotomy”and“knee osteoarthritis”were searched(date of search December 20,2019)on PubMed to identify articles evaluating the biomechanical and clinical outcomes of PFO in patients with knee osteoarthritis.A total of 258 were retrieved.After reviewing the summary of the texts,22 articles written in English were marked for abstract review.Articles that were case studies or cadaver experiments were excluded.The abstracts of the remaining articles were read,and only those that focused on the history,outcomes of case studies and technical considerations of PFO were included in the review.A total of 12 articles were included in this review.RESULTS At least six studies reported improvement in the visual analogue scale(VAS)from the average preoperative VAS score[6.32,95%confidence interval(CI)=(4.05,8.59)]to average postoperative VAS score[1.23,95%CI:(-1.20,3.71)],which was statistically significant.Similarly,the American Knee Society Score(KSS)functional score improved from an average preoperative KSS functional score[43.11,95%CI:(37.83,48.38)]to postoperative KSS functional score[66.145,95%CI:(61.94,70.35)],which was statistically significant.The femorotibial angle improved by around 7º,and the hip knee ankle angle improved by around 6º.CONCLUSION With the existing data,it seems that PFO is a viable option for treating medial joint osteoarthritis in selected patients.Long term outcome studies and progression of disease pathology are some of the important parameters that need to be addressed by use of multicenter randomized controlled trials.
