Clinical features of unilateral multilobar and hemispheric polymicrogyria (PMG)-related epilepsy and seizure outcome with different treatment options.

To provide evidence for choosing surgical or nonsurgical treatment for epilepsy in patients with unilateral multilobar and hemispheric polymicrogyria (PMG). We searched published studies until September 2022 related to unilateral multilobar and hemispheric PMG and included patients who were followed up at the Pediatric Epilepsy Centre of Peking University First Hospital in the past 10 years. We summarized the clinical characteristics and compared the long-term outcomes after surgical or nonsurgical (anti-seizure medications, ASMs) treatment. A total of 70 patients (49 surgical, 21 non-surgical) with unilateral multilobar and hemispheric PMG were included. The median age at epilepsy onset was 2.5 years (1.0-4.1). The most common seizure types were focal and atypical absence seizures. In the whole cohort, 87.3% had hemiparesis and 67.1% had electrical status epilepticus during slow sleep (ESES). There were significant differences in age at epilepsy onset, extent of lesion, and EEG interictal discharges between the two groups. At the last follow-up (median 14.1 years), the rates of seizure-freedom (81.6% vs. 57.1%, p = 0.032) and ASM discontinuation (44.4% vs. 6.3%, p = 0.006) were higher in the surgical group than in the nonsurgical group. Patients in the surgical group had a higher rate of seizure-freedom with complete resection/disconnection than with subtotal resection (87.5% vs. 55.6%, p = 0.078), but with no statistically significant difference. In the nonsurgical group, more extensive lesions were associated with worse seizure outcomes. Cognition improved postoperatively in 90% of surgical patients. In patients with unilateral multilobar and hemispheric PMG, the age of seizure onset, the extent of the lesion and EEG features can help determine whether surgery should be performed early. Additionally, surgery could be more favorable for achieving seizure freedom and cognitive improvement sooner. We aim to summarize clinical characteristics and compare the long-term outcomes after surgical and nonsurgical (ASM) treatment to provide a basis for treatment decisions for patients with unilateral multilobar and hemispheric polymicrogyria (PMG)-related epilepsy. We found that patients with unilateral hemispheric and multilobar PMG had significantly higher rates of seizure freedom and ASM discontinuation with surgical treatment than with nonsurgical treatment. In the surgical group, seizure outcomes were better in patients treated with complete resection/disconnection than in those treated with subtotal resection, but the difference was not statistically significant.

The effects of surgical resection in the treatment of limited-stage small cell lung cancer: a multicenter retrospective study.

This study aimed to examine the effects of surgical resection on the treatment of limited-stage small cell lung cancer and identify patient characteristics that may indicate a benefit from surgical resection.We retrospectively reviewed medical data from patients diagnosed with small cell lung cancer between January 2013 and December 2020 at three hospitals. A total of 478 patients were included in the study, 153 patients received surgery treatment and 325 patients received non-surgery treatment. Survival differences between the surgical resection group and the nonsurgical resection group were analyzed using the Kaplan-Meier method and the log-rank test.The overall survival in the surgical resection group was significantly improved compared to that in the nonsurgical resection group (HR: 0.58, 95% CI: 0.370-0.876, p = 0.0126). Surgical resection significantly improved overall survival compared to nonsurgical resection in stage I disease (HR: 0.56, 95% CI: 0.34-0.94, p = 0.029) and stage IIA disease (HR: 0.60, 95% CI: 0.40-0.92, p = 0.019). However, no significant differences in overall survival were found between surgical resection and nonsurgical resection in stage IIB disease (HR: 0.86, 95% CI: 0.57-1.29, p = 0.46) and stage III disease (HR: 0.99, 95% CI: 0.71-1.39, p = 0.97). The overall survival of patients who underwent lobectomy was significantly better than that of patients who underwent sublobular resection (HR: 1.85, 95% CI: 1.15-4.16, p = 0.021) and who underwent pneumonectomy (HR: 2.04, 95% CI: 1.29-5.28, p = 0.009).Surgical resection should be recommended for patients diagnosed with stage I-IIA SCLC. When deciding on the surgical type, it is preferable to choose lobectomy over sublobar resection or pneumonectomy.

Responsiveness and clinically important differences of the Western Ontario Rotator Cuff (WORC) Index in surgical and non-surgical treatment groups with different follow-up periods: A systematic review and meta-analysis

Background This study reviews and meta-analyzes the responsiveness and minimal clinically important difference (MCID) of the Western Ontario Rotator Cuff (WORC) Index for various patient populations and treatment durations. Methods A comprehensive search in PubMed, Embase, Web of Science, and CINAHL identified studies on the responsiveness or MCID of the WORC in shoulder conditions. Two authors independently screened articles. Study quality was appraised using COSMIN and GRADE guidelines. Responsiveness was evaluated using anchor-based MCID and distribution-based standardized mean differences (SMDs) computed with Hedges’ g. A random-effect model addressed study variability, and heterogeneity was assessed with the chi-squared test and I² statistic. Results The 12 studies yielded high-quality evidence supporting the WORC's responsiveness. A meta-analysis of 1326 observations revealed a significant overall effect size (SMD) of 0.91 (95% CI: 0.56 to 1.26; p < 0.0001), with high heterogeneity ( I² = 91.2%). Subgroup analyses showed larger effect sizes for long-term follow-ups (SMD = 1.28) and surgical treatments (SMD = 1.14). The average MCID was 17 for conservative treatments within six months, 26 for surgical procedures, and 29 for follow-ups over six months. Conclusion The WORC measures improvements in rotator cuff conditions, with varying MCID values for different treatments and durations.

Outcomes and prognosis of postpartum hemorrhage according to management protocol: an 11-year retrospective study from two referral centers

BackgroundNo standard treatment guidelines have been established for postpartum hemorrhage (PPH). We aimed to assess the differences in outcomes and prognoses between patients with PPH who underwent surgical and non-surgical treatment.MethodsThis retrospective study included 230 patients diagnosed with PPH at two referral hospitals between August 2013 and October 2023. The patients were divided into non-surgical (group 1, n = 159) and surgical intervention groups (group 2, n = 71). A subgroup analysis was performed by dividing the surgical intervention group into immediate (n = 45) and delayed surgical intervention groups (n = 26).ResultsInitial lactic acid levels and shock index were significantly higher in group 2 (2.85 ± 1.37 vs. 4.54 ± 3.63 mmol/L, p = 0.001, and 0.83 ± 0.26 vs. 1.10 ± 0.51, p < 0.001, respectively). Conversely, initial heart rate and body temperature were significantly lower in group 2 (92.5 ± 21.0 vs. 109.0 ± 28.1 beat/min, p < 0.001, and 37.3 ± 0.8 °C vs. 37.0 ± 0.9 °C, p = 0.011, respectively). Logistic regression analysis identified low initial body temperature, high lactic acid level, and shock index as independent predictors of surgical intervention (p = 0.029, p = 0.027, and p = 0.049, respectively). Regarding the causes of PPH, tone was significantly more prevalent in group 1 (57.2% vs. 35.2%, p = 0.002), whereas trauma was significantly more prevalent in group 2 (24.5% vs. 39.4%, p = 0.030). Group 2 had worse overall outcomes and prognoses than group 1. The subgroup analysis showed significantly higher rates of uterine atony combined with other causes, hysterectomy, and disseminated intravascular coagulopathy in the delayed surgical intervention group than the immediate surgical intervention group (42.2% vs. 69.2%, p = 0.027; 51.1% vs. 73.1%, p = 0.049; and 17.8% vs. 46.2%, p = 0.018, respectively).ConclusionsPatients with PPH presenting with increased lactic acid levels and shock index and decreased body temperature may be surgical candidates. Additionally, immediate surgical intervention in patients with uterine atony combined with other causes of PPH could improve prognosis and reduce postoperative complications.

Improved survival after primary tumor resection in distant metastasis medullary thyroid carcinoma: a population-based cohort study with propensity score matching

Few studies have investigated the impact of primary tumor resection (PTR) on patients with distant metastasis medullary thyroid carcinoma (DMMTC). This population-based study aims to assess the application of PTR in DMMTC patients, ascertain its benefits, and identify optimal surgical indications. DMMTC Patients diagnosed between 2010 and 2020 were included through the Surveillance, Epidemiology, and End Results (SEER) program. Logistic regression analysis identified driving factors of surgical decision-making. Propensity score matching (PSM), Kaplan–Meier method, and Cox regression were utilized to compare overall survival (OS) and disease-specific survival (DSS) between surgical and non-surgical groups. Subgroup analyses were performed to determine optimal surgical indications. Of 238 DMMTC patients included, 122 (51.3%) patients underwent PTR. Extrathyroidal extension and N1 stage emerged as independent factors promoting the surgical decision. PSM-adjusted survival analyses revealed significant advantages in both OS and DSS for the surgical group. Moreover, subgroup analyses indicated that except for patients aged ≥ 65 years, tumors ≤ 20 mm, or with multiple metastasized sites (> 1), the others significantly benefit from PTR. PTR significantly improves prognosis in selected DMMTC patients. The decision to undergo PTR in other patients should be based on a comprehensive assessment of the disease, surgeon’s experience, and family discussions for potential survival benefits.

Non-surgical management of acute proximal hamstring avulsions can produce clinically acceptable results.

To evaluate the mid-term clinical outcomes for the non-surgical and surgical management of acute proximal hamstring avulsions. Sixty physically active individuals were offered surgical or non-surgical management for their proximal hamstring avulsion injuries. Distal retraction was defined as greater than 2 cm. Primary outcome measures were the Victorian Institute of sport assessment-proximal hamstring tendons (VISA-H) and functional assessment scale for acute hamstring injuries (FASH). Secondary outcome measures included palpable gap (cm), return to sport (RTS) and the ability to perform Nordic hamstring curls. Outcome variables were adjusted in regression models for gender, age, and treatment. Thirty-one patients elected to undertake non-surgical management, and 29 chose surgery with a mean follow-up of 34.8 ± 8.7 and 34.9 ± 7.0 months, respectively. The mean VISA-H for the non-surgical and surgical groups were 87.3 ± 3.4 and 87.9 ± 4.1 (n.s.), respectively. The mean FASH for the non-surgical group was 89.3 ± 2.4 and 88 ± 3.6 for the surgical group (n.s.). This was consistent after adjusting for confounders. The mean gap for the non-surgical group was 4.5 ± 1.09and 4.9 ± 1.19 cm for the surgical group (n.s.). No significant differences were found in the abilities to perform Nordic hamstring curls (n.s.). Both groups achieved comparable RTS rates (n.s.). On average, the non-surgical group achieved RTS at 5.5 ± 1.2 months post-injury, whereas the surgical group was at 5.7 ± 0.7 months (n.s.). Physically active individuals with acute proximal hamstring avulsions and distal retraction of the tendon stump can be managed non-surgically, achieving similar functional levels and RTS compared to patients treated surgically. Level III.

Predictors of Alcohol Use, Alcohol-Related Problems, and Substance Use Following Adolescent Metabolic and Bariatric Surgery.

To identify factors associated with incident alcohol consumption, hazardous drinking, alcohol-related problems, and substance use up to 8 years following metabolic and bariatric surgery (MBS) during adolescence. In this cohort, nearly half of those who underwent MBS as adolescents screened positive for alcohol use disorder, symptoms of alcohol-related harm, or alcohol-related problems within 8 years post-surgery. Moreover, persistent or heavy marijuana use following MBS during adolescence is higher than national data. This study includes 217 adolescents (aged 13-19 years) enrolled in a 5-center prospective cohort study who underwent Roux-en-Y gastric bypass or vertical sleeve gastrectomy between 2007 and 2011 and were followed for up to 8 years. Participants self-reported alcohol use via the Alcohol Use Disorders Identification Test and substance use for up to 8 years. Female sex, pre-surgery lower body mass index, and pre-surgery substance use were independently associated with increased risk of incident post-surgery hazardous drinking. Pre-surgery psychiatric counseling was significantly associated with increased risk for new-onset substance use post-surgery. Starting substance use post-surgery or continuing pre- to post-surgery was independently associated with a higher risk of post-surgery hazardous drinking. Greater percent weight loss, starting post-surgery or continuing pre- to post-surgery psychiatric counseling, using alcohol, and hazardous drinking were independently associated with a higher risk of post-surgery substance use. Future research with a nonsurgical control group should be examined to further elucidate the relationships between MBS and alcohol and substance use following surgery during adolescence.

Non-surgical vs. surgical treatment of distal radius fractures: a meta-analysis of randomized controlled trials

PurposeTo compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture.MethodsWe performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS).ResultsThere were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P < 0.001). And in grip strength (%), the results showed a significant improvement in surgical treatment compared with non-surgical treatment (WMD − 6.60, 95% CI (-11.61, -1.60), P = 0.01). There was significant difference in radial inclination, radial length, volar title, range of wrist pronation, range of wrist supination. However, no difference in radial deviation, ulnar deviation, ulnar variance, range of wrist extension and range of wrist flexion was observed.ConclusionsThe results of this meta-analysis suggest that some patients with surgical treatment of distal radius fractures not only improved the grip strength (%), decreased the DASH score, but also improved the range of wrist pronation and the range of wrist supination compared with nonsurgical treatment. Based on the present meta-analysis, we suggest that some patients with surgical treatment might be more effective in patients with distal radius fracture.

Prevalence of neurocognitive disorders 5 years after elective orthopaedic surgery.

Peri-operative neurocognitive disorders are one of the most common complications affecting older adults after anaesthesia and surgery. It is not clear how exposure to surgery and anaesthesia contributes to the prevalence of long-term neurocognitive disorders. This study aimed to report the prevalence of neurocognitive disorders, and explore pre-operative factors associated with neurocognitive disorders 5 years after elective orthopaedic surgery. A prospective, 5-year longitudinal, cohort study was performed recruiting patients (aged ≥ 60 y) undergoing elective orthopaedic surgery and a contemporaneous non-surgical control group. Neurocognitive disorder was evaluated and classified at baseline and 5-year review incorporating: self- and informant-reported cognition; functional participation; and performance on neuropsychological tests. Recruitment at 5-year follow-up included 195 patients and 21 control participants. In the patient cohort the prevalence of neurocognitive disorder was 38.1% (n = 75), with 61 (30.1%) meeting the criteria for mild neurocognitive disorder and 14 (7.1%) for major neurocognitive disorder. At 5-year follow-up, 121 (61.4%) patients were classified with a neurocognitive disorder, with 88 (44.7%) characterised with mild neurocognitive disorder and 33 (16.8%) with major neurocognitive disorder. Age (odds ratio (95%CI) 1.07 (1.02-1.13); p = 0.01) and baseline cognitive impairment (odds ratio (95%CI) 2.1 (1.06-4.15); p = 0.03) were significant predictors of neurocognitive disorder 5 years after surgery. More than half of older adult patients had some form of neurocognitive disorder 5 years after elective orthopaedic surgery. Surgery and anaesthesia may be associated with the trajectory of cognitive decline in at-risk older adults, including those with pre-operative cognitive impairment. Cognitive screening should be factored into pre-operative assessments of older adults to inform subsequent care.

Efficacy of cytoreductive surgery for metastatic upper tract urothelial carcinoma: a Surveillance, Epidemiology and End Results (SEER) study of 508 patients.

Cisplatin-based combination chemotherapy alone is currently considered the standard of care for patients with metastatic upper tract urothelial carcinoma (mUTUC). However, less research has been done on the efficacy of other combinations. In this study, we explored the role of cytoreductive surgery in patients with mUTUC receiving different types of systemic therapy. Data from 9,436 anonymized records were abstracted from the Surveillance, Epidemiology, and End Results (SEER) database between 2008-2018. Of these, 508 individuals received systemic therapy subsequent to being diagnosed with mUTUC. These patients had all been treated with systemic therapies such as chemotherapy and/or radiotherapy. Patients were stratified into either a non-surgical or surgical group based on cytoreductive surgery status before systemic therapeutics commenced. Kaplan-Meier curves were used to compare overall survival (OS) and cancer-specific survival (CSS). Cox's proportional hazard models were then used to analyze prognostic factors related to OS and CSS. Of the 508 cases, 36.8% (n=187) had received cytoreductive surgery with systemic treatments. The remaining 63.2% (n=321) received either chemotherapy and/or radiotherapy alone. Kaplan-Meier curves showed that 11.6% had 3-year OS [95% confidential interval (CI): 7.1-17.3] for cytoreductive surgery with systemic treatment and 4.9% (95% CI: 2.7-8.0) for systemic treatment alone (P=0.001). The 3-year CSS was 14.9% for cytoreductive surgery plus systemic treatment (95% CI: 9.4-21.7%) and 6.0% (95% CI: 3.4-9.8%) for systemic treatments alone (P=0.003). Under multivariate regression analysis, primary ureter site OS had a hazard ratio (HR) of 0.74 (95% CI: 0.58-0.95, P=0.02) and a CSS HR of 0.72 (95% CI: 0.56-0.94, P=0.01). The cytoreductive surgery OS HR was 0.79 (95% CI: 0.65-0.95, P=0.02) and the CSS HR was 0.75 (95% CI: 0.61-0.92, P=0.006). Additionally, chemotherapy had an OS HR of 0.46 (95% CI: 0.33-0.0.65, P<0.001) and a CSS HR of 0.44 (95% CI: 0.31-0.63, P<0.001). Bones and liver metastases were also indicative of poorer prognosis. Validation was conducted through subgroup analysis which suggested cytoreductive surgery was effective only for patients who received chemotherapy or combined chemo-radiotherapy but not for radiotherapy alone. Cytoreductive surgery provided significantly increased OS and CSS for mUTUC patients who received chemotherapy or combined chemo-radiotherapy in this study. In addition, the primary tumor and metastatic sites were shown to be related to improved patient survival although this was a small and relatively homogeneous cohort of study, sample therefore, further research is required.

Outcomes from a single institution cohort of 248 patients with stage I–III esophageal cancer treated with radiotherapy: Comparison of younger and older populations

Outcomes for patients receiving radiotherapy (RT) for non-metastatic esophageal cancer at a single institution were assessed, as well as the impact of factors including age and intensity modulated RT (IMRT) planning on patient outcomes. A retrospective cohort of patients treated with RT for stage I-III esophageal cancer between 2010 and 2018 was identified. Among 248 identified patients, 28 % identified as older (≥75 years of age). Other than histology, there were no other statistically significant differences in patient and tumour characteristics between the younger and older populations. Treatments varied between the two age groups, with significantly less older patients completing trimodality treatments (17 % vs 58 %). Median overall survival (M−OS) and progression-free survival (M−PFS) were 20 months and 12 months for all patients and 40 months and 26 months for trimodality patients, respectively. In the older patients, the M−OS improved from 13 months for all to 34 months for trimodality patients; and M−PFS from 10 months to 16 months. On multivariate analysis, the use of trimodality therapy showed improved OS (HR 0.26, p < 0.001). In the non-surgical older patient group, significantly better survival was seen in patients who had a heart V30Gy under 46 %. There was no significant difference in M−OS in patients planned with IMRT compared with 3D-conformal RT. Clinical outcomes in the treatment of esophageal cancer vary significantly by treatment approach, with the most favourable results in those receiving trimodality therapy. Among older patients deemed fit after assessment by the multidisciplinary team for trimodality treatments, the M−OS is comparable to the younger patient group.

Long-Term Echocardiographic and Clinical Outcomes After Invasive and Non-Invasive Therapies for Sub-Massive and Massive Acute Pulmonary Embolism

Acute pulmonary embolism (PE) is a significant cause of mortality in the hospital setting. The objective of this study was to outline the long-term outcomes after surgical and non-surgical management for patients with massive and submassive PE. Population cohort observational study evaluating all patients who presented to three tertiary hospitals in the state of Western Australia with access to cardiothoracic services over 5 years (2013-2018). Reviewed notes of all patients as well as radiology, linked mortality data and all available echocardiography studies at the primary hospital. In total, 245 patients were identified, of which 41 received surgical management and 204 non-surgical management; demographic data was similar. Clinically, the surgical group had higher rates of shock requiring vasopressors, severe bradycardia, or cardiopulmonary resuscitation prior to intervention. The 28-day mortality was not statistically significantly different between the surgical embolectomy group (2/41 [4.2%]) and the non-surgical group (17/201 [8.3%]) (p=0.382). There was no difference in 12-month mortality, including when this was adjusted for vasopressors, right ventricular (RV) strain, troponin, and brain natriuretic peptide. In the massive PE sub-group, 28-day mortality was not significantly different: 2/29 (6.9%) surgical group vs 7/34 (20.2%) non-surgical group (p=0.064). Higher rates of severe RV impairment and dilatation were present in the surgical group. All patients with available echocardiography studies at outpatient follow-up returned to normal or mild RV impairment. Patients who presented with massive or submassive PE had similar outcomes whether treated with surgical or non-surgical management. Surgical embolectomy is a safe option in a cardiothoracic centre setting.

Adverse Cardiovascular Outcomes in Patients With Obstructive Sleep Apnea and Obesity: Metabolic Surgery vs Usual Care

BackgroundNo therapy has been shown to reduce the risk of major adverse cardiovascular events (MACE) and death in patients with obstructive sleep apnea (OSA). ObjectivesThe authors sought to investigate the long-term relationship between metabolic surgery and incident MACE in patients with OSA and obesity. MethodsAdult patients with a body mass index 35 to 70 kg/m2 and moderate-to-severe OSA at a U.S. health system (2004-2018) were identified. Baseline characteristics of patients who underwent metabolic surgery were balanced with a nonsurgical control group using overlap-weighting methods. Multivariable Cox regression analysis estimated time-to-incident MACE. Follow-up ended in September 2022. ResultsA total of 13,657 patients (7,496 [54.9%] men; mean age 52.0 ± 12.4 years; median body mass index 41.0 kg/m2 [Q1-Q3: 37.6-46.2 kg/m2]), including 970 patients in the metabolic surgery group and 12,687 patients in the nonsurgical group, with a median follow-up of 5.3 years (Q1-Q3: 3.1-8.4 years) were analyzed. The mean between-group difference in body weight at 10 years was 26.6 kg (95% CI: 25.6-27.6 kg) or 19.3% (95% CI: 18.6%-19.9%). The 10-year cumulative incidence of MACE was 27.0% (95% CI: 21.6%-32.0%) in the metabolic surgery group and 35.6% (95% CI: 33.8%-37.4%) in the nonsurgical group (adjusted HR: 0.58 [95% CI: 0.48-0.71]; P < 0.001). The 10-year cumulative incidence of all-cause mortality was 9.1% (95% CI: 5.7%-12.4%) in the metabolic surgery group and 12.5% (95% CI: 11.2%-13.8%) in the nonsurgical group (adjusted HR: 0.63 [95% CI: 0.45-0.89]; P = 0.009). ConclusionsAmong patients with moderate-to-severe OSA and obesity, metabolic surgery, compared with nonsurgical management, was associated with a significantly lower risk of incident MACE and death.

Retrospective study of 189 cases of acute perforated peptic ulcer: safety and efficacy of over-the-scope-clip based endoscopic closure.

To compare the clinical outcomes in patients with acute perforated peptic ulcer (PPU) treated with over-the-scope clip (OTSC), non-surgical, and surgical interventions, and to explore the effectiveness and safety of OTSC closure. Hospital stay, antibiotic use, diet resumption time, and mortality rate were analyzed retrospectively. Binary Logistic regression analysis was used to identify the risk factors influencing PPU complicated with sepsis. Patients were divided into three treatment groups: OTSC (n = 62), non-surgical (n = 72), and surgical (n = 55) groups. The median time (IQR) from symptom onset to admission was 9.0 (4-23) h. 88.71% (55/62) of the patients in In the OTSC group underwent OTSC closure within 24h (median [IQR] time: 14.5 [7.00-30.25] h). The perforation diameters in the OTSC and surgical groups were 9.87mm ± 5.97mm and 8.55mm ± 6.17mm, respectively. The median (IQR) hospital stays in the OTSC (9.50 [7.00-12.25] days) and non-surgical group (9.00[7.00-13.00]days) were similar (p > 0.05), but shorter than that in surgical group (12.00[10.00-16.00]days), (p < 0.05). The median duration of antibiotic use was shorter in the OTSC group (7.00[3.00-10.00]) than in the non-surgical group (9.00[7.00-11.00]) and surgical group (11.00[9.00-13.00]) ( p < 0.05); and the time to resume oral feeding was shorter in the OTSC group (4.00[2.00-5.25]) than in the non-surgical group (7.00[6.13-9.00]) and surgical group (8.00[6.53-10.00]), respectively ( p < 0.05). No mortality difference among groups (p = 0.109) was found. Lower albumin level at admission, older age, and elevated creatinine levels were associated with increased sepsis risk, with OR(95%CI) of 0.826 (0.687-0.993), 1.077 (1.005-1.154), and 1.025 (1.006-1.043), respectively (all p < 0.05). OTSC closure improves clinical outcomes of acute PPU patients without sepsis. Age, hypoalbuminemia, and baseline renal dysfunction increase the risk of sepsis, while mortality was associated with sepsis and multiorgan dysfunction.

Percutaneous vertebroplasty/kyphoplasty contributes to the improved outcome in patients with newly diagnosed multiple myeloma: A single center cohort study

ObjectiveTo evaluate the efficacy and prognosis of percutaneous vertebroplasty/kyphoplasty (PVP/PKP) in patients with newly diagnosed multiple myeloma (NDMM). MethodsClinical data of NDMM patients who underwent PVP/PKP during front-line regimen at Peking Union Medical College Hospital from January 1, 2003, to June 30, 2023, were analyzed. Patients with comparable bone diseases not receiving orthopedic surgery were selected as controls. Visual analogue scale (VAS) score, progression-free survival (PFS), and overall survival (OS) were compared. ResultsBaseline characteristics were matched between the surgical group (n = 51 with 56 surgeries) and non-surgical group (n = 102), including demographics, tumor load, International Staging System (ISS), bone diseases, cytogenetic abnormalities, first-line treatment, and autologous stem-cell transplantation (ASCT). Bone lesions for PVP/PKP were located at thoracic vertebrae (53.6 %, 30/56) or lumbosacral vertebrae (46.4 %, 26/56). The postoperative VAS score was significantly improved (2.25 ± 0.81 vs 5.92 ± 1.05, P < 0.001). The median follow-up time was 51[38–70] months. Kaplan-Meier survival analysis suggested that both PFS (37[17–89] vs 23[12–61] months, HR 0.648, 95 %CI 0.431–0.973, P = 0.047) and OS (not reached vs 66[28-NR] months, HR 0.519, 95 %CI 0.296–0.910, P = 0.045) were significantly prolonged in the surgical group. COX multivariate analysis suggested that PVP/PKP was an independent prognostic factor for PFS (P = 0.021, HR 0.589, 95 %CI 0.376–0.922) and OS (P = 0.038, HR 0.496, 95 %CI 0.255–0.963). Subgroup analysis confirmed that patients with ISS II/III or non-ASCT achieved better PFS and OS in the surgical group (PFS: P = 0.033, P = 0.040; OS: P = 0.024, P = 0.018 respectively), while similar survival outcome was observed in patients with ISS I or ASCT between two groups. ConclusionFor NDMM patients, not only does PVP/PKP alleviate bone pain, meanwhile, it improves the PFS and OS in advanced subpopulation or non-transplant myeloma patients, which suggests that shortening the gap from symptom onset to diagnosis by orthopedic surgery favors clinical prognosis.

Outcomes after surgical and nonsurgical treatment of pediatric cerebral cavernous malformation.

Pediatric cerebral cavernous malformation (CCM) is a rarely encountered vascular entity. Comparative study on surgical excision and nonsurgical management outcomes of CCM in pediatrics is limited. To determine the demographic characteristics, hemorrhage rate, and long-term outcomes of pediatric patients with CCM. A retrospective study of pediatric patients with CCM in Chinese PLA General Hospital was conducted between January 2004 and January 2019. We compared the clinical characteristics, radiological features, and outcomes of the surgical and nonsurgical groups. Seventy-nine children were included, with 69.6% being boys, and the average age was 11.8 ± 5.5 years. The annual retrospective hemorrhagic rate was 5.7% per patient per year. Fifty-six children (70.9%) underwent surgical excision, and they were more likely to present with seizure symptoms (P = 0.011), have a higher proportion of larger lesion size (P = 0.008), less likely to have durations ≤10 days (P = 0.048), and less likely to have supratentorial deep CCM (P = 0.014) compared to children who received nonsurgical management. Total resection was achieved in most surgical cases (55, 98.2%). During the 143.9 ± 50.8 months of follow-up, 44 patients (78.6%) achieved improvement, 12 patients (17.8%) remained the same, and two (3.6%) experienced worsening. In the nonsurgical management group, 14 children (60.9%) experienced symptom improvement, eight (34.8%) remained the same, and one (4.3%) worsened, with a re-hemorrhagic risk of 8.7%. Surgical removal of pediatric CCM can eliminate the risk of hemorrhage and lead to satisfactory outcomes. For children undergoing nonsurgical management, long-term close monitoring is essential due to the life-long risk of hemorrhage.

Renoprotective Effects of Metabolic Surgery Versus GLP1 Receptor Agonists on Progression of Kidney Impairment in Patients with Established Kidney Disease.

To examine the renoprotective effects of metabolic surgery in patients with established chronic kidney disease (CKD). The impact of metabolic surgery compared with glucagon-like peptide-1 receptor agonists (GLP-1RA) in patients with established CKD has not been fully characterized. Patients with obesity (body mass index ≥30kg/m 2 ), type 2 diabetes, and baseline estimated glomerular filtration rate (eGFR) 20-60mL/min/1.73 m² who underwent metabolic bariatric surgery at a large US health system (2010-2017) were compared with nonsurgical patients who continuously received GLP-1RA. The primary end point was CKD progression, defined as a decline of eGFR by ≥50% or to <15mL/min/1.73m 2 , initiation of dialysis, or kidney transplant. The secondary end point was the incident kidney failure (eGFR <15mL/min/1.73m 2 , dialysis, or kidney transplant) or all-cause mortality. 425 patients, including 183 patients in the metabolic surgery group and 242 patients in the GLP-1RA group, with a median follow-up of 5.8 years (IQR, 4.4-7.6), were analyzed. The cumulative incidence of the primary end point at 8 years was 21.7% (95% CI: 12.2-30.6) in the surgical group and 45.1% (95% CI: 27.7 to 58.4) in the nonsurgical group, with an adjusted hazard ratio of 0.40 (95% CI: 0.21 to 0.76), P =0.006. The cumulative incidence of the secondary composite end point at 8 years was 24.0% (95% CI: 14.1 to 33.2) in the surgical group and 43.8% (95% CI: 28.1 to 56.1) in the nonsurgical group, with an adjusted HR of 0.56 (95% CI: 0.31 to 0.99), P =0.048. Among patients with type 2 diabetes, obesity, and established CKD, metabolic surgery, compared with GLP-1RA, was significantly associated with a 60% lower risk of progression of kidney impairment and a 44% lower risk of kidney failure or death. Metabolic surgery should be considered as a therapeutic option for patients with CKD and obesity.

The effect of thoracic trauma scoring system in thoracic trauma patients with rib fracture

Objective Rib fractures are common in thoracic trauma patients. There are various factors, including flail chest, pulmonary contusion, and accompanying conditions, affecting morbidity and mortality. The study aimed to identify high-risk patients for morbidity and mortality with a scoring system that the authors created. Methods Cases over the age of 18 admitted due to trauma and diagnosed with rib fractures between 1 January 2019 and 1 March 2023, were included. Trauma scores were determined by applying the new trauma scoring system. Trauma scores and other variables regarding morbidity and mortality were evaluated. Results A total of 1023 cases were included in the study. The total trauma scores were higher in bilateral and multiple fractures. In those without respiratory failure, the total score was statistically significantly lower than in the groups with respiratory failure. The total score was significantly higher in those who needed surgery, those who were hospitalized, and those who needed intensive care compared to the non-surgical groups. However, there was no correlation between intensive care unit stay and total score. Trauma mechanism, presence of additional extrathoracic pathology, and thoracic trauma-age score were independent predictors of survival. Conclusion The present study demonstrated that the number of rib fractures and the presence of pulmonary contusion did not have an effect on mortality and morbidity. The presence of extrathoracic pathology and age significantly affect survival.

Barriers to resection following neoadjuvant chemotherapy for resectable pancreatic adenocarcinoma: A national and local perspective.

Neoadjuvant chemotherapy (NAC) use for pancreatic ductal adenocarcinoma (PDAC) has increased, but some patients never get resection following NAC. Data from January 2012 to December 2019 for all clinically resectable patients across two health networks were utilized, as well as data from the ACS NCDB registry. Univariate testing, multivariable logistic regression, and survival analyses were employed to evaluate failure to resection after neo-adjuvant chemotherapy. Of the 10 007 registry patients eligible for resection, the resected group was younger (64.6 vs. 69.5 years; p < 0.001) and had a slightly lower mean comorbidity index (0.41 vs. 0.45; p < 0.001) than the nonsurgical group. The nonsurgical group was composed of a higher percentage of Black and Hispanic patients (17.5 vs. 13.1%; p < 0.001). After adjusting for age and comorbidities, the factors associated with decreased probability of resection after NAC were evaluation at a community hospital (OR 2.4), Black or Hispanic race (OR 1.6), areas of increased high school drop-out rates (OR 1.4), and lack of private health insurance (OR 1.3). The median overall survival for nonsurgery was markedly worse than the surgical cohort (10.6 vs. 26.6 months; p < 0.001). The most frequent reasons for a lack of definitive resection were operative upstaging to unresectable (39.6%), patient preference (14.5%), progression on NAC (13.2%), deconditioning or comorbidity severity (12.5%), and nonreferral to a surgeon (8.8%). Racial, economic, and educational disparities have a considerable influence on the successful completion of a neoadjuvant approach for resectable PDAC. A comprehensive closed or highly collaborative/communicative multidisciplinary neoadjuvant program is optimal for treatment success and completion.

Treatment and Outcomes of 844 Cases of Pneumothorax in Heritable Connective Tissue Disorders

BackgroundCharacteristics, practice patterns, and clinical outcomes of secondary spontaneous pneumothorax (SSP) with heritable connective tissue disorders (Marfan, Ehlers-Danlos, and Birt-Hogg-Dubé syndromes) are unclear. MethodsA nationwide Japanese inpatient database that included data of 524 patients with SSP (884 hospitalizations) and 137,821 with primary spontaneous pneumothorax between July 2010 and March 2020 was used in this study. Hospitalization for SSP (n = 884) was categorized into surgical (n = 459) and nonsurgical (n = 425) groups, and the patient characteristics, treatment, and outcomes were compared between the groups. Multivariable analyses were performed to evaluate risk factors for pneumothorax recurrence. We also compared the characteristics of patients with different underlying heritable connective tissue disorders. ResultsCompared with the nonsurgical group, the surgical group had less frequent readmission for pneumothorax (26% vs 44%; hazard ratio, 0.47; 95% CI, 0.38-0.58). Young patients (2.46; 1.83-3.32) or those with Birt-Hogg-Dubé syndrome (2.53; 1.77-3.63) had a high risk of recurrence. Pneumothorax occurred frequently in teenagers with Marfan syndrome, in those aged 20 to 39 years with Ehlers-Danlos syndrome, and in those aged ≥40 years with Birt-Hogg-Dubé syndrome. ConclusionsDetailed information on the characteristics and clinical course of SSP in heritable connective tissue disorders will aid in the clinical decision-making process.
