The Beijing angle closure progression study: design and methodology.

Purpose: The purpose of this study is to summarize the design and methodology of a large-scale trial in northern China, the Beijing Angle Closure Progression Study (BAPS). This trial is designed to explore the 5-year incidence of primary angle-closure suspect (PACS) progressing to primary angle-closure (PAC) or primary angle-closure glaucoma (PACG) and to determine the possible risk factors of disease progression. Methods/design: The BAPS is a clinic-based, multicenter, noninterventional trial conducted on a sample of urban Chinese adults. Consecutive eligible patients who meet PACS diagnostic criteria will be recruited from eight participating centers, with the trial commencing on August 4, 2022. The target sample size is set at 825 subjects, with follow up planned for a minimum period of 5 years. Baseline examination will include presenting visual acuity, best corrected visual acuity, intraocular pressure (IOP), undilated slit-lamp biomicroscopy, stereoscopic evaluation of the optic disc, visual field test, optical coherence tomography evaluation of retinal nerve fiber layer, ultrasound biomicroscopy and IOLMaster. Questionnaires will also be used to collect detailed personal history. Patients are scheduled to visit the glaucoma clinic every 12 months and may visit the emergency room in case of acute attack of angle closure. Study endpoints include acute PAC episodes, elevated IOP, peripheral anterior synechiae, glaucomatous visual field defect, or glaucomatous abnormality of optic nerve. Discussion: The BAPS will provide data on the 5-year incidence of PACS progressing to PAC or PACG and determine the risk factors for disease progression. This study will also help redefine high-risk patients with PACS.

Is Popliteus Tendon a Redundant Structure in Total Knee Arthroplasty?

Background: Many studies have shown that injury to the popliteus tendon has little consequence for the static stability of the knee following total knee arthroplasty (TKA). However, very few studies have evaluated the effect of intraoperative iatrogenic popliteus tendon injury on the patient-reported outcome measures (PROMs) following TKA. This study aimed to determine the incidence of iatrogenic popliteus tendon injury in our subset of the population and to find out its effect on PROMs. Methods: 100 consecutive osteoarthritic varus knees with flexion deformities less than 20° were operated upon by a single senior experienced arthroplasty surgeon. Patients were assessed intraoperatively for any iatrogenic popliteus tendon injury, the injury site, and the amount of injury which was quantified and graded. PROMs applied for assessment at 1-year follow-up were Knee Society Score (KSS 1), Knee Function Score (KSS 2), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Results: 17% of cases had an iatrogenic popliteus tendon injury. Thirteen had grade II injuries, whereas four had grade III injuries. There was no statistical significance in post-operative knee mobility and PROMs among those with popliteus tendon injury versus non-injured patients. Conclusion: The incidence of iatrogenic popliteus tendon injury is higher than what we expected. The tendon injury remains a risk, but it is unclear how the popliteus tendon injury will affect patients after the TKA. In our series, such an injury during knee replacement does not affect the functioning of the knee in the short term; however, a long-term follow-up is warranted.

Management of Refractory/Resistant Herpes Simplex Virus Infections in Haematopoietic Stem Cell Transplantation Recipients: A Literature Review.

Herpes simplex virus (HSV) infections in allogeneic haematopoietic stem cell transplantation (HSCT) recipients pose significant challenges, with higher incidence, severity, and risk of emergence of resistance to antivirals due to impaired T-cell mediated immunity. This literature review focuses on acyclovir-refractory/resistant HSV infections in HSCT recipients. The review addresses the efficacy of antiviral prophylaxis, the incidence of acyclovir-refractory/resistant HSV infections, and the identification of risk factors and potential prognostic impact associated with those infections. Additionally, alternative therapeutic options are discussed. While acyclovir prophylaxis demonstrates a significant benefit in reducing HSV infections in HSCT recipients and, in some cases, overall mortality, concerns arise about the emergence of drug-resistant HSV strains. Our systematic review reports a median incidence of acyclovir-resistant HSV infections of 16.1%, with an increasing trend in recent years. Despite limitations in available studies, potential risk factors of emergence of HSV resistance to acyclovir include human leucocyte antigen (HLA) mismatches, myeloid neoplasms and acute leukaemias, and graft-versus-host disease (GVHD). Limited evidences suggest a potentially poorer prognosis for allogeneic HSCT recipients with acyclovir-refractory/resistant HSV infection. Alternative therapeutic approaches, such as foscarnet, cidofovir, topical cidofovir, optimised acyclovir dosing, and helicase-primase inhibitors offer promising options but require further investigations. Overall, larger studies are needed to refine preventive and therapeutic strategies for acyclovir-refractory/resistant HSV infections in allogeneic HSCT recipients and to identify those at higher risk.

Decreased incidence of peritoneal dialysis-associated peritonitis in young children.

AIM: Peritonitis is the most common complication of peritoneal dialysis (PD). This study aimed to investigate changes in the incidence, risk factors, microbiology, and clinical outcomes of PD-associated peritonitis in the past decades. METHODS: This was a retrospective study that included children who initiated chronic PD at our institution between 2000 and 2017. The patients were divided into two groups according to the year of initiation: those who initiated PD between 2000 and 2008 and those who initiated PD between 2009 and 2017. The incidence and characteristics of peritonitis were compared between the groups. RESULTS: A total of 184 patients with a median age of 10.2 years were included in this study. Of the patients, 92 experienced 210 episodes of peritonitis. The incidence rate of peritonitis decreased from 0.35 to 0.21 episodes/patient year during the study period (P = 0.001). During the 2000-2008 period, the 2-year peritonitis-free survival rate was significantly lower for patients under 2 years of age than for the other age groups (P = 0.004), whereas this was not observed during the 2009-2017 period. The multivariable Cox proportional hazard model showed that the <2 years age group had a significantly higher risk of developing peritonitis in the 2000-2008 period. However, this was not evident in the 2009-2017 period. CONCLUSIONS: The incidence of PD-associated peritonitis decreased, particularly in children under 2 years of age. Thus, younger age may not be a risk factor for PD-associated peritonitis.

Prevalence and Characteristics by Age and Sex in Pediatric Trigger Digits: Nationwide Analysis Using Korea Health Insurance Dataset.

Background: Pediatric trigger digit (TD) does not appear at birth but is diagnosed after birth by finding a flexion contracture of the thumb or other fingers. The reported incidence of pediatric TDs varies from 0.5 to 5 cases per 1,000 live births without sex-specific predominance. We performed a nationwide large-scale study to determine the prevalence and incidence of pediatric TDs and analyzed operative treatment for pediatric TDs using the National Health Insurance data of South Korea. Methods: Patients with pediatric TDs, aged 0-10 years between 2011 and 2020, were included in this study. Children born between 2011 and 2015 were set as the reference population and followed up until 2020. We calculated the prevalence and incidence rates of pediatric TDs according to age and sex and analyzed the operation rate, age at surgery, time interval from initial diagnosis to surgery, and follow-up period. Patient selection and treatment were based on International Classification of Diseases, 10th Revision (ICD-10). Results: The prevalence rates of pediatric TDs ranged from 0.063% to 0.084%. Girls had a higher prevalence rate (0.066%-0.094%) than boys (0.060%-0.075%). The total incidence rate was 77.6/100,000 person-years, and the incidence rate was higher in girls (84.8) than in boys (70.7). Among 2,181,814 children born between 2011 and 2015, 12,729 were diagnosed with pediatric TDs, of which 1,128 (8.9%) underwent operative management. The means of age at initial diagnosis, age at surgery, and the time interval between diagnosis and operation were 2.76 ± 1.91 years, 3.79 ± 2.19 years, and 1.15 ± 1.71 years, respectively. Conclusions: High prevalence and incidence rates of pediatric TDs were found in 2- to 3-year-old patients. Among pediatric patients, 8.9% underwent operative management that was most frequently conducted between 2 and 3 years of age (within 1 year of initial diagnosis).

Pneumonitis Incidence in Patients With Metastatic Non-small Cell Lung Cancer on Immunotherapy: A Systematic Review and Meta-Analysis.

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, often diagnosed at the advanced stage (metastatic). Treatment options for metastatic NSCLC include radiotherapy, chemotherapy, target drug therapy, and immunotherapy. Immunotherapy (utilization of checkpoint inhibitors) boosts the immune system to recognize and destroy cancer cells. However, it is often associated with immune-related complications such as pneumonitis. This review aims to determine the incidence of pneumonitis in metastatic NSCLC patients treated with different immunotherapy drugs. PubMed, Cochrane Library, and Embase databases were scoured for randomized controlled trials (RCTs) until October 2023. Published RCTs with similar research objectives were included, while non-English articles, reviews, case reports, ongoing trials, non-randomized studies, conference abstracts, and studies on small cell lung cancer (SCLC) were excluded. The Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to assess the risk of bias among the included studies. The statistical analyses were performed with the Comprehensive Meta-Analysis software. The subgroup analysis of the 16 included RCTs showed that metastatic NSCLC patients treated with nivolumab and pembrolizumab had a higher incidence of any grade pneumonitis than those treated with atezolizumab (4.5% and 5.1% vs. 1.6%, respectively). Similarly, the incidence of grade ≥3 pneumonitis was higher among patients receiving nivolumab (1.3%) and pembrolizumab (2.4%) than those receiving atezolizumab (0.7%). Furthermore, the subgroup analysis showed that patients with naive-treated NSCLC on immunotherapy had a higher incidence of any grade pneumonitis than those with previously treated NSCLC (6.5% vs. 3.9%). Treatment-naive patients recorded higher grade ≥3 pneumonitis incidences than those previously treated (3.1% vs. 1.3%). Programmed death 1 (PD-1) inhibitors (i.e., pembrolizumab and nivolumab) have higher incidences of pneumonitis than programmed death-ligand 1 inhibitors (atezolizumab).

Impact of preoperative age-adjusted sagittal imbalance on radiographic and clinical outcomes following 1-level minimally invasive transforaminal lumbar interbody fusion for degenerative spondylolisthesis.

OBJECTIVE: Prior studies investigating the use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for treatment of degenerative lumbar conditions and concomitant sagittal deformity have not stratified patients by preoperative pelvic incidence (PI)-lumbar lordosis (LL) mismatch, which is the earliest parameter to deteriorate in mild sagittal deformity. Thus, the aim of the present study was to determine the impact of preoperative PI-LL mismatch on clinical outcomes and sagittal balance restoration among patients undergoing MI-TLIF for degenerative spondylolisthesis (DS). METHODS: Consecutive adult patients undergoing primary 1-level MI-TLIF between April 2017 and April 2022 for DS with ≥ 6 months radiographic follow-up were included. Patient-reported outcome measures (PROMs) included the Oswestry Disability Index, visual analog scale (VAS), 12-Item Short-Form Health Survey (SF-12), and Patient-Reported Outcomes Measurement Information System at preoperative, early postoperative (< 6 months), and late postoperative (≥ 6 months) time points. The minimal clinically important difference (MCID) for PROMs was also evaluated. Radiographic parameters included PI, LL, pelvic tilt (PT), and sagittal vertical axis (SVA). Patients were categorized into balanced and unbalanced groups based on preoperative PI-LL mismatch according to age-adjusted alignment goals. Changes in radiographic parameters and PROMs were evaluated. RESULTS: Eighty patients were included (L4-5 82.5%, grade I spondylolisthesis 82.5%, unbalanced 58.8%). Mean clinical and radiographic follow-up were 17.0 and 8.3 months, respectively. The average preoperative PI-LL was 18.8° in the unbalanced group and -3.3° in the balanced group. Patients with preoperative PI-LL mismatch had significantly worse preoperative PT (26.2° vs 16.4°, p < 0.001) and SVA (53.2 vs 9.0 mm, p = 0.001) compared with balanced patients. Patients with preoperative PI-LL mismatch also showed significantly worse PI-LL (16.0° vs 0.54°, p < 0.001), PT (25.9° vs 18.7°, p < 0.001), and SVA (49.4 vs 22.8 mm, p = 0.013) at long-term follow-up. No significant radiographic improvement was observed among unbalanced patients. All patients demonstrated significant improvements in all PROMs (p < 0.05) except for SF-12 mental component score. Achievement of MCID for VAS back score was significantly greater among patients with preoperative PI-LL mismatch (85.7% vs 65.5%, p = 0.045). CONCLUSIONS: Although 1-level MI-TLIF did not restore sagittal alignment in patients with preoperative PI-LL mismatch, patients presenting with DS can expect significant improvement in PROMs following 1-level MI-TLIF regardless of preoperative alignment or extent of correction. Thus, attaining good clinical outcomes in patients with mild sagittal imbalance may not require addressing imbalance directly.

Early-onset cancer incidence in the United States by race/ethnicity between 2011 and 2020.

We characterized trends in early onset (aged 20-49) cancer incidence by race/ethnicity and sex using the 2011-2020 Surveillance, Epidemiology, and End Results (SEER) Program dataset. We estimated age-standardized cancer incidence rates, incidence rate ratios (IRR), and annual percentage changes (APC) with 95 % confidence intervals (CI). During the time period examined, cancer incidence increased for female breast (APC: 0.64; 95 % CI: 0.10, 1.20), female colorectal (APC: 2.16; 95 % CI: 1.22, 3.10), and male colorectal (APC: 2.49; 95 % CI: 1.81, 3.19) cancer. Among racial/ethnic groups examined, Hispanic individuals had the largest increases in female all sites (APC: 1.31; 95 % CI: 0.38, 2.25), female breast (APC: 1.04; 95 % CI: 0.29, 1.81), and female (APC: 4.67; 95 % Cl: 3.07, 6.30) and male (APC: 3.53; 95 % CI: 2.58, 4.49) colorectal cancer incidence. Further research is needed to clarify the causal mechanisms driving these patterns.

The association of initial and changes in serum A-FABP level with the development and improvement of pre-sarcopenia.

CONTEXT: Several cross-sectional studies have reported the association between serum adipocyte fatty acid binding protein (A-FABP) level and pre-sarcopenia. However, data on the impacts of serum A-FABP level and its changes over time on the development and improvement of pre-sarcopenia are scarce. METHODS: This longitudinal cohort study included 1496 adults (41.2% men; median age, 58 [53-63] years) in 2013-2014 and was followed up to 2015-2016. Participants underwent serum A-FABP level measurements at baseline and follow-up visit. Visceral fat area (VFA) was measured using magnetic resonance imaging. Skeletal muscle mass (SMM) was estimated by bioelectrical impedance analysis and converted to skeletal muscle index (SMI). Pre-sarcopenia was defined as SMI < 1 standard deviation of the sex-specific mean for the young reference group. RESULTS: During an average follow-up period of 2.1 years, baseline serum A-FABP level was positively associated with the incidence of pre-sarcopenia (standardized by weight: risk ratio [RR] 3.22, 95% confidence interval [CI] 1.96-5.38; standardized by VFA: RR 2.11, 95%CI 1.29-3.51) and negatively associated with the improvement of pre-sarcopenia (standardized by weight: RR 0.66, 95%CI 0.45-0.97; standardized by VFA: RR 0.71, 95%CI 0.54-0.94), regardless of whether SMM was standardized by weight or VFA. Moreover, changes in serum A-FABP level provided additional information on the incidence and improvement of pre-sarcopenia, independent of baseline serum A-FABP level (all P < 0.05). CONCLUSIONS: Baseline serum A-FABP level and its changes were positively associated with the incidence, and negatively associated with the improvement of pre-sarcopenia.

Incidence and prevalence of Alzheimer's disease in China: a systematic review and meta-analysis.

As China faces demographic shifts and socioeconomic changes, the burden of Alzheimer's disease (AD) and associated cognitive impairments is increasing dramatically, with significant implications for public health and the economy. This systematic review and meta-analysis aims to provide a comprehensive assessment of the prevalence and incidence of AD across China. Drawing from an extensive search of international and Chinese databases up to August 27, 2023, including PubMed, Embase, and the Cochrane Library, we synthesized data from 105 studies. Our analysis reveals a combined prevalence of AD of 3.48% within a sample of 626,276 elderly individuals and an incidence rate of 7.90 per 1000 person-years. Subgroup and meta-regression analyses highlight age and gender as pivotal factors influencing these epidemiological patterns. Notably, significant heterogeneity exists due to variations in diagnostic criteria and study quality, impacting the comparability of findings. This meta-analysis underscores the need for continued research into demographic and modifiable risk factors influencing AD, while emphasizing standardized reporting practices to address these limitations and improve the understanding of AD's challenge in China.

The netball injury evidence base: a scoping review of methodologies and recommendations for future approaches.

BACKGROUND: Netball is a sport with a large participation base and a high risk of injuries. Effective injury prevention strategies are dependent upon a clear understanding of injury issues, aetiology and mechanisms, requiring robust research methodologies to ensure a reliable evidence base. This scoping review aims to identify the characteristics and range of netball injury research methodologies, to inform recommendations for future research. METHODS: A systematic search of SPORTDiscus, MEDLINE, CINAHL and Academic Search Complete, PubMed, Scopus and Web of Science, from 1985 to May 2023 identified relevant studies. Inclusion criteria included peer-reviewed studies assessing injury incidence, aetiology and mechanisms in netball. RESULTS: Following screening, 65 studies were included (68% descriptive epidemiology, 32% analytic epidemiology). Descriptive epidemiology reported data from hospital/clinic and insurance databases (57%) and netball competitions (43%). Only two studies used ongoing, systematic injury surveillance in netball cohorts, and significant heterogeneity existed in study designs, data collection methods, injury definitions and injury incidence rates calculations. Studies assessed a limited number of risk factors (descriptive competition studies: median: n = 4; analytic studies median: n = 6), with 76% using a simplistic reductionist approach to determine causality. Basic descriptions and retrospective recall of injury mechanisms reduced accuracy. Only two studies conducted comprehensive assessments of injury mechanisms using video-based methods. CONCLUSION: To establish an accurate netball injury evidence base, future research should prioritise the development of reliable, continuous surveillance systems. The International Olympic Committee (IOC) consensus statement guidelines are recommended for accurate injury data collection and reporting. A multifactorial approach should be adopted to assess the complex interaction between multiple risk factors, player load and the injury inciting event. Comprehensive descriptions of injury mechanisms using video methods, alongside descriptions from medical staff are recommended. This information is crucial for developing targeted prevention strategies.

Incidence of laboratory-confirmed influenza and RSV and associated presenteeism and absenteeism among healthcare personnel, Israel, influenza seasons 2016 to 2019.

BackgroundHealthcare personnel (HCP) are at high risk for respiratory infections through occupational exposure to respiratory viruses.AimWe used data from a prospective influenza vaccine effectiveness study in HCP to quantify the incidence of acute respiratory infections (ARI) and their associated presenteeism and absenteeism.MethodsAt the start and end of each season, HCP at two Israeli hospitals provided serum to screen for antibodies to influenza virus using the haemagglutination inhibition assay. During the season, active monitoring for the development of ARI symptoms was conducted twice a week by RT-PCR testing of nasal swabs for influenza and respiratory syncytial virus (RSV). Workplace presenteeism and absenteeism were documented. We calculated incidences of influenza- and RSV-associated ARI and applied sampling weights to make estimates representative of the source population.ResultsThe median age of 2,505 participating HCP was 41 years, and 70% were female. Incidence was 9.1 per 100 person-seasons (95% CI: 5.8-14.2) for RT-PCR-confirmed influenza and 2.5 per 100 person-seasons (95% CI: 0.9-7.1) for RSV illness. Each season, 18-23% of unvaccinated and influenza-negative HCP seroconverted. The incidence of seroconversion or RT-PCR-confirmed influenza was 27.5 per 100 person-seasons (95% CI: 17.8-42.5). Work during illness occurred in 92% (95% CI: 91-93) of ARI episodes, absence from work in 38% (95% CI: 36-40).ConclusionInfluenza virus and RSV infections and associated presenteeism and absenteeism were common among HCP. Improving vaccination uptake among HCP, infection control, and encouraging sick HCP to stay home are important strategies to reduce ARI incidence and decrease the risk of in-hospital transmission.

Clinical Characteristics of Moxifloxacin-Related Arrhythmias and Development of a Predictive Nomogram: A Case Control Study.

This study aimed to analyze the incidence, clinical characteristics, and risk factors of moxifloxacin-related arrhythmias and electrocardiographic alterations in hospitalized patients using real-world data. Concurrently, a nomogram was established and validated to provide a practical tool for prediction. Retrospective automatic monitoring of inpatients using moxifloxacin was performed in a Chinese hospital from January 1, 2017, to December 31, 2021, to obtain the incidence of drug-induced arrhythmias and electrocardiographic alterations. Propensity score matching was conducted to balance confounders and analyze clinical characteristics. Based on the risk and protective factors identified through logistic regression analysis, a prediction nomogram was developed and internally validated using the Bootstrap method. Arrhythmias and electrocardiographic alterations occurred in 265 of 21,711 cases taking moxifloxacin, with an incidence of 1.2%. Independent risk factors included medication duration (odds ratio [OR] 1.211, 95% confidence interval [CI] 1.156-1.270), concomitant use of meropenem (OR 4.977, 95% CI 2.568-9.644), aspartate aminotransferase >40 U/L (OR 3.728, 95% CI 1.800-7.721), glucose >6.1 mmol/L (OR 2.377, 95% CI 1.531-3.690), and abnormally elevated level of amino-terminal brain natriuretic peptide precursor (OR 2.908, 95% CI 1.640-5.156). Concomitant use of cardioprotective drugs (OR 0.430, 95% CI 0.220-0.841) was a protective factor. The nomogram showed good differentiation and calibration, with enhanced clinical benefit. The incidence of moxifloxacin-related arrhythmias and electrocardiographic alterations is in the range of common. The nomogram proves valuable in predicting the risk in the moxifloxacin-administered population, offering significant clinical applications.

Head and neck squamous cell carcinoma (HNSCC) in solid organ transplant recipients - Results from the scientific registry of transplant recipients (SRTR) database.

BACKGROUND: Solid organ transplant recipients have an elevated risk of cancer following organ transplantation than the age-adjusted general population. We assessed incidence of head and neck squamous cell carcinoma (HNSCC) in heart, lung, and liver recipients. BASIC PROCEDURES/METHODS: This retrospective cohort study included 124,966 patients from the United States Scientific Registry of Transplant Recipients (SRTR) database who received heart, lung, or liver transplantation between 1991 and 2010. Follow-up data were available until 2018. Patients with prevalent HNSCC at transplantation were excluded. Incident cases of HNSCC post organ transplantation were identified, and incidence rates (per 100,000 person-years) were reported by gender, race, organ type, year and age at organ transplantation. MAIN FINDINGS: The majority of patients received liver transplantation (58.64 %), followed by heart (28.64 %), and lung (12.72 %) transplantation. During follow-up, 4.14 % patients developed HNSCC. Overall incidence rate of HNSCC was 426.76 per 100,000 person-years. Male recipients had a higher HNSCC incidence rate than female recipients (571.8 and 177.0 per 100,000 person-years, respectively). Lung recipients had the highest overall HNSCC incidence rate (1273.6 per 100,000 person-years), followed by heart (644.2 per 100,000 person-years), and liver recipients (207.1 per 100,000 person-years). Overall, an increase in HNSCC incidence rate was observed with increase in age at organ transplantation. An increase in incidence rates of HNSCC over time was observed in lung recipients; however, incidence rates decreased over time in heart recipients. CONCLUSION: Solid organ transplant recipients have a high incidence of HNSCC following organ transplantation, and the incidence varies by type of organ received.

Association of continuous subcutaneous insulin therapy and diabetic retinopathy in type 1 diabetes: A national cohort study.

AIM: This study aimed to investigate the short-and long-term effect on diabetic retinopathy (DR) in individuals with type 1 diabetes treated with continuous subcutaneous insulin injections (CSII) compared to those using multiple daily injections (MDI). METHODS: We conducted a register-based matched cohort study utilizing data from the Danish Registry of Diabetic Retinopathy as well as several other national Danish health registers. Our cohort consisted of all individuals with type 1 diabetes who attended the Danish screening program for DR from 2013 to 2022. We included individuals registered with CSII treatment, and compared them to individuals using MDI, matched by age, sex, and DR level. Cox regression analysis was performed to evaluate the outcomes. RESULTS: The study included 674 individuals treated with CSII and 2006 matched MDI users. In our cohort 53.4 % were female and median age was 36 (IQR 27-47). Average follow-up risk-time was 4.8 years. There was no difference in the risk of DR worsening between the CSII group and MDI group (HR 1.05 [95%CI 0.91; 1.22], p = 0.49). However, an increased risk of focal photocoagulation was observed in the CSII group (HR 2.40 [95%CI 1.11; 5.19], p = 0.03). CONCLUSIONS: Our findings indicate that CSII treatment does not confer a significant difference in the overall short- and long-term risk of DR worsening or ocular intervention compared to MDI treatment. These results provide insights into the DR outcomes of CSII treatment in individuals with type 1 diabetes.

Prediabetes and the risk of peripheral artery disease: a meta-analysis.

BACKGROUND: Peripheral artery disease (PAD) is a significant vascular condition that can lead to severe complications, including limb ischemia and cardiovascular events. This meta-analysis aims to evaluate the association between prediabetes, an intermediate state between normoglycemia and diabetes, and the risk of developing PAD. METHODS: A comprehensive search of PubMed, EMBASE, and Web of Science databases was conducted to identify relevant cohort studies up to April 12, 2024. Data extraction was performed independently by two reviewers, and any discrepancies were resolved by consensus. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated using a random-effects model to account for heterogeneity among studies. RESULTS: A total of eight cohort studies comprising 90133 participants were included in the meta-analysis. The pooled analysis revealed that individuals with prediabetes had a significantly higher risk of PAD compared to those with normoglycemia (RR = 1.27, 95% CI: 1.13-1.42, p < 0.001; I2 = 55%). Subgroup analyses indicated that the association was stronger in prediabetes defined by mildly elevated hemoglobin A1c (RR: 1.47) compared to those defined by impaired fasting glucose (RR: 1.21) or impaired glucose tolerance (RR: 1.17, p for subgroup difference < 0.001). In addition, a stronger association was observed for studies reporting clinically diagnosed PAD compared to studies that included asymptomatic PAD (RR: 1.32 versus 0.92, p for subgroup difference = 0.02). CONCLUSIONS: This meta-analysis demonstrates a significant association between prediabetes and an increased risk of PAD in generally community-derived population.

Epidemiology of ANCA vasculitis in Northern Spain.

OBJECTIVES: The incidence of anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) shows disparate results due to variable classification criteria and heterogeneous-population series. We aimed to estimate the incidence of AAV in a well-defined population with standardized classification criteria. METHODS: Population-based study of AAV patients diagnosed from January 2000 to December 2023 in Cantabria, Northern Spain. Patients were classified according to ACR/EULAR 2022 into granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), or unclassified vasculitis if the criteria were not met. Eosinophilic granulomatosis with polyangiitis (EGPA) patients were not included. The annual incidence rates were estimated by cases over 1,000 000 (106) (95% CI) including overall AVV, type of AAV, sex, and year of diagnosis. A literature review was also performed. RESULTS: We included 152 (80/72 men; mean age; 70.6 ± 13.18 years) patients. They were classified as MPA (67; 44%), GPA (64; 42.2%), and unclassified vasculitis (21; 13.8%). Annual incidence was 13.4 (10-16.8)/106 [male 14.5 (10.5-18.5); female 12.1 (8.7-15.6)]. The Annual incidence of MPA was 5.9 (4-7.8)/106 and GPA 5.6 (3.9-7.3)/106. The mean Annual incidence increased from 6.1 (4.5-7.7)/106-16.5 (5.6-27.4)/106 in the last three years, particularly, in GPA from 2.3 (0.3-4.9)/106-8.2 (2-14.5)/106. The prevalence of AAV was 184.7 (181-188)/106. CONCLUSION: During a 20-year period we found that the incidence of AAV (GPA and MPA) in Northern Spain is higher than Southern Spain, but lower than Northern European countries. An increase in the incidence was observed in the last years.

Incidence and nationwide estimates of cryptogenic ischemic stroke or TIA eligible for prolonged cardiac rhythm monitoring.

INTRODUCTION: Current guidelines indicate prolonged cardiac rhythm monitoring for atrial fibrillation screening in patients with cryptogenic ischemic stroke (IS) or transient ischemic attack (TIA). This study aimed to assess the incidence of cryptogenic IS/TIA eligible for such investigation, and to estimate the number of patients potentially concerned in whole France annually. METHODS: All cryptogenic acute IS/TIA cases ⩾35 years old were retrieved from the population-based Dijon Stroke Registry, France (2013-2020). Patients eligible for prolonged cardiac rhythm monitoring were defined after excluding those who died in-hospital or within the first 30 days, or with preexisting major impairment. Annual incidence rates of eligible cryptogenic IS/TIA were calculated by age groups and sex. The total number of eligible patients in France was estimated by standardization to age- and sex-specific incidence. RESULTS: Among 2811 IS/TIA patients recorded in the Dijon Stroke Registry, 1239 had cryptogenic IS/TIA of whom 1045 were eligible for prolonged cardiac rhythm monitoring (517 IS and 528 TIA, mean age 73.6 ± 14.6 years old, 55.4% women). Crude incidence rates of eligible cryptogenic IS/TIA were 169/100,000 per year (95% CI: 159-179) in overall sexes, 83/100,000 per year (95% CI: 76-91) for IS, and 85/100,000 per year (95% CI: 78-93) for TIA. The total number of patients with cryptogenic IS/TIA eligible for prolonged cardiac rhythm monitoring in France was estimated to be 66,125 (95% CI: 65,622-66,630) for the calendar year 2022, including 32,764 (95% CI: 32,410-33,120) with IS and 33,361 (95% CI: 33,004-33,721) with TIA. CONCLUSIONS: This study demonstrated a high incidence of cryptogenic IS/TIA eligible for prolonged cardiac rhythm monitoring. Estimates at a national level pointed out the large number of patients who may require access to such atrial fibrillation screening, with attention to be paid on regarding organization of care networks and related costs.

Global, regional, and national burden of early-onset gastric cancer.

OBJECTIVE: The burden of gastric cancer (GC) across different age groups needs updating. We determined the GC global, regional, and national burden profiles and changes in incidence for 3 sequential 5-year intervals from 2003 to 2017. METHODS: The latest incidence and mortality estimates of GC from 185 countries and regions were extracted from the GLOBOCAN 2022 database. The 5-year interval age-standardised incidence rates (ASIRs) were evaluated using cancer registry data from volumes X-XII of the Cancer Incidence in Five Continents (CI5). Correlation analysis was used to evaluate the relationship between ASIR or the age-standardised mortality rate (ASMR) and the Human Development Index (HDI). RESULTS: There was an estimated global 968,000 new GC cases and 660,000 deaths in 2022, with male predominance. GC ASIRs and ASMRs were 9.2 and 6.1 per 100,000 persons, respectively. East Asia had the highest burden, with 53.8% of cases and 48.2% of deaths among all geographic regions. There was a significant correlation between ASIR and HDI. Over three 5-year intervals from 2003 to 2017, the incidence of GC notably decreased in most countries but peaked at 2008-2012 in New Zealand, Turkey, and South Africa. Several countries in Europe, Oceania, and America suggest an increasingly concerning trend among younger individuals, especially females. CONCLUSIONS: GC is a significant health issue, especially among males and in geographic regions with an HDI, such as eastern Asia. While the incidence of GC is decreasing in many countries due to prevention efforts and improved treatments, a rising trend persists among younger individuals. Comprehensive prevention strategies tailored to different age patterns are clearly needed.

Can pelvic incidence affect changes in sagittal spino-pelvic parameters between standing and sitting positions in individuals with lumbar degenerative disease?

OBJECTIVE: The aim of this study was to explore the correlation between PI and standing-to-sitting changes of the sagittal alignment in patients with lumbar degenerative diseases, and investigate the differences in posture changes among Roussouly types. METHODS: A total of 209 patients with lumbar degenerative disease were retrospectively included in this study. All the patients received lateral full body imaging in both standing and sitting positions. Sagittal parameters including SVA, OD-HA, PT, PI, PT/PI, SS, LL, TK, Upper LL (L1-L4) and Lower LL (L4-S1) were measured in both standing and sitting position, and the parameters were compared between two positions. The correlations between PI and lumbo-pelvic changes were analyzed. The postural changes were compared among different Roussouly types. RESULTS: From standing to sitting, all the parameters except PI significantly changed, including SVA, OD-HA, PT, PT/PI, SS, LL, TK, Upper LL and Lower LL. The contribution of lower LL was greater to global LL than upper LL. PI had a significant correlation with ΔPT, ΔSS, ΔLL, ΔUpper LL and ΔLower LL. From standing to sitting, type 4 patients had the most pronounced ΔPT, ΔSS and ΔLL, and ΔLower LL of types 3 and 4 were greater than that of types 1 and 2. CONCLUSIONS: In patients with degenerative disease, PI plays an important role in determining the extent of lumbo-pelvic changes from standing to sitting. Among different Roussouly types, type 4 patients have the most pronounced changes of PT, SS and LL, suggesting the relatively greater flexibility of pelvis and lumbar spine.
