Metabolic Dysfunction-Associated Steatotic Liver Disease Is Associated with Increased Risk of Kidney Cancer: A Nationwide Study.

Background: This study investigated the association between metabolic dysfunction-associated steatotic liver disease (MASLD) and Kidney Cancer Risk, as the incidence of both diseases gradually increases owing to metabolic health issues. Methods: Participants (aged 20-79) undergoing a national health examination between 2009 and 2010 were monitored for new-onset kidney cancer. The MASLD spectrum was classified as non-MASLD, MASLD, or MASLD with increased alcohol uptake (MetALD). Kidney Cancer Risk associated with the MASLD spectrum was estimated using multivariate Cox proportional hazard models. Age- and sex-stratified analyses were also performed. Results: Among 8,829,510 participants (median follow-up 13.3 years), the proportion of non-MASLD, MASLD, and MetALD was 64.9%, 30.3%, and 4.7%, respectively, with newly developed kidney cancer in 17,555 participants. Kidney cancer was significantly increased with MASLD (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.46-1.56) and MetALD (aHR 1.51, 95% CI 1.42-1.61), compared with the non-MASLD group. Kidney Cancer Risk was the highest among young populations (aHR 1.93, 95% CI 1.77-2.11 for MASLD and aHR 1.91, 95% CI 1.65-2.22 for MetALD), according to stratification analysis. Furthermore, the cumulative relationship between metabolic dysfunction and Kidney Cancer Risk was confirmed across all MASLD spectra. Conclusions: Our study highlights the positive association between MASLD and Kidney Cancer Risk, emphasizing a comprehensive approach to metabolic health. This also serves as a call to devote closer attention to the metabolic health of younger patients.

Association between diabetic status and risk of acute pancreatitis: A nationwide population-based study.

OBJECTIVE: There have been several epidemiologic studies on the association between diabetes mellitus and acute pancreatitis. However, there is no solid evidence, and the effect of diabetes mellitus severity on acute pancreatitis incidence is not well known. This study aimed to evaluate the association between diabetic status and the risk of acute pancreatitis in a nationwide population-based cohort. METHODS: Among the participants who underwent national health examinations between 2009 and 2012, patients with diabetes mellitus were included. Patients diagnosed with acute pancreatitis before the health examination or diagnosed with pancreatitis within 1 year following the examination were excluded. The association between the number of oral hypoglycemic agents (<3 or ≥3) or insulin use during examination and acute pancreatitis occurrence was analyzed after follow-up until December 31, 2018. RESULTS: Overall, 2,444,254 patients were included in the final analysis. During the follow-up period, acute pancreatitis occurred in 10,360 patients with an incidence ratio of 0.585 per 1,000 person-years, and it was observed that the risk of acute pancreatitis sequentially increased between patients taking oral hypoglycemic agents <3 (incidence ratio = 0.546), those taking ≥3 (incidence ratio = 0.665), and those using insulin (incidence ratio = 0.872). The adjusted hazard ratios of patients taking three or more hypoglycemic agents and those using insulin were 1.196 (95% confidence interval (CI) 1.123-1.273) and 1.493 (95% CI 1.398-1.594), respectively. CONCLUSIONS: As diabetes mellitus severity increases, the risk of acute pancreatitis increases.

Risk of depression in amyotrophic lateral sclerosis: A nationwide cohort study in South Korea.

Depression is frequently reported in amyotrophic lateral sclerosis (ALS) due to the disastrous prognosis of progressive motor impairment, but the risk of depression in ALS is still unclear. Therefore, we investigated the risk of depression in ALS and analyzed the effect of ALS-related physical disability on the risk of developing depression using the Korean National Health Insurance Service (KNHIS) database. A total of 2241 ALS patients, as defined by the International Classification Diseases (ICD, G12.21) and Rare Intractable Disease codes (V123), and 1:10 sex- and age-matched controls were selected from the KNHIS. After applying exclusion criteria (non-participation in national health screening, history of depression, or having missing data), 595 ALS patients and 9896 non-ALS individuals were finally selected. Primary outcome is newly diagnosed depression during follow-up duration defined by ICD code (F32 or F33). A Cox regression model was used to examine the hazard ratios (HRs) after adjustment for potential confounders. During the follow-up period, 283 cases of depression in the ALS group and 1547 in the controls were recorded. The adjusted HR for depression in ALS was 9.1 (95% confidence interval [CI] 7.87-10.60). The risk of depression was slightly higher in the disabled ALS group (aHR 10.1, 95% CI 7.98-12.67) than in the non-disabled ALS group (aHR 8.78, 95% CI 7.42-10.39). The relative risk of depression was higher in younger patients than in older patients, and in obese patients than in non-obese patients. Our study showed that ALS patients have an increased risk of depression compared to non-ALS individuals.

Multifocal motor neuropathy in Japan: A nationwide survey on prevalence, clinical profiles, and treatment.

INTRODUCTION/AIMS: Multifocal motor neuropathy (MMN) is a rare disease for which epidemiological and clinical data are limited. We conducted a nationwide survey to determine disease prevalence, incidence, clinical profile, and current treatment status in Japan. METHODS: A nationwide survey was conducted in 2021 using an established epidemiological method. Questionnaires were sent to all neurology and pediatric neurology departments in Japan. An initial questionnaire was administered to determine the number of patients with and incidence of MMN. A second questionnaire was administered to collect detailed clinical information. The European Federation of Neurological Societies/Peripheral Nerve Society 2010 guidelines were used as diagnostic criteria. RESULTS: The estimated number of patients with MMN was 507. The estimated prevalence was 0.40 per 100,000 individuals. Detailed clinical profiles were available for 120 patients. The male-to-female ratio was 2.3:1 and the median onset age was 42 years. The median disease duration at diagnosis was 25 months. Most patients presented with upper limb-dominant muscle weakness. Motor nerve conduction blocks were found in 62% of patients and positive anti-GM1 IgM antibody results in 54%. A total of 117 (98%) patients received immunoglobulin therapy, and 91% of them showed improvement. At the time of the last visit (median, 82 months from treatment initiation), 89 (74%) patients were receiving maintenance immunoglobulin therapy. A slight progression of neurological deficits was observed during follow-up. DISCUSSION: Most patients with MMN in Japan received induction and maintenance immunoglobulin therapies, which appear to suppress long-term disease progression.

Anti-epileptic drug use and subsequent degenerative dementia occurrence.

INTRODUCTION: The use of anti-epileptic drugs (AEDs) in degenerative dementia (DD) remains uncertain. We aimed to evaluate the association of early AED administration with subsequent DD occurrence. METHODS: Using a large nationwide database, we enrolled patients newly diagnosed with epilepsy from 2014 to 2019 (n = 104,225), and using propensity score matching, we divided them into treatment (those prescribed AEDs in 2014) and control groups. The primary outcome was subsequent DD occurrence in 2019. RESULTS: Overall, 4489 pairs of patients (2156 women) were matched. The odds ratio (treatment/control) for DD occurrence was 0.533 (95% confidence interval: 0.459-0.617). The DD proportions significantly differed between the treatment (340/4489 = 0.076) and control (577/4489 = 0.129) groups. DISCUSSION: Among patients newly diagnosed with epilepsy, compared to non-use, early AED use was associated with a lower occurrence of subsequent DD. Further investigations into and optimization of early intervention for epilepsy in DD are warranted. Highlights: Anti-epileptic drug (AED) use before epilepsy diagnosis was linked with a lower subsequent degenerative dementia (DD) occurrence.Identifying the epileptic phenotype was crucial for justifying early AED use in DD.AED use with an epilepsy diagnosis did not pose an additional risk of DD.The potential contribution of combination drug therapy to the strategy was noted.

Mortality in elderly Parkinson's disease patients with long-term care needs: A nationwide population-based study in Korea.

BACKGROUND: The effects of long-term care insurance (LTCI) in reducing medical costs and utilization among older adults have been reported. This study aims to investigate the mortality in patients with Parkinson's disease (PD) requiring LTCI and its relationships with economic status. METHODS: This study was conducted using the database of the Korean National Health Insurance Service (NHIS)-Senior Cohort between 2008 and 2019. A total of 5937 patients with PD were included. Hazard ratios (HRs) of mortality associated with LTCI were estimated using a Cox regression model. Potential confounders such as demographics and comorbidities were adjusted. RESULTS: Out of 5937 PD patients, 821 required LTCI, and 5116 did not. Compared to PD patients without LTCI, PD patients with LTCI were older and exhibited a higher comorbidity burden. The overall incidence rate of mortality was 18.63 per 100 person-years in PD patients with LTCI. PD patients requiring LTCI were associated with an increased HR of 3.61 (95 % CI = 3.13-4.16) for mortality compared to PD patients not eligible for LTCI. Low-income status with LTCI was associated with the highest mortality risk (HR = 4.54, 95 % CI = 3.38-6.09), compared to middle-income status (HR = 3.47, 95 % CI = 2.64-4.61) and high-income status (HR = 3.53, 95 % CI = 2.91-4.91). CONCLUSIONS: Our study suggests that older PD patients requiring LTCI with low economic status have a higher risk of death. Continuous policy efforts to reduce the mortality risk in this group are needed.

Inequality in Mortality and Cardiovascular Risk Among Young, Low-Income, Self-Employed Workers: Nationwide Retrospective Cohort Study.

Background: Self-employment is a significant component of South Korea's labor force; yet, it remains relatively understudied in the context of occupational safety and health. Owing to different guidelines for health checkup participation among economically active individuals, disparities in health maintenance may occur across varying employment statuses. Objective: This study aims to address such disparities by comparing the risk of all-cause mortality and comorbidities between the self-employed and employee populations in South Korea, using nationwide data. We sought to provide insights relevant to other countries with similar cultural, social, and economic contexts. Methods: This nationwide retrospective study used data from the Korean National Health Insurance Service database. Participants (aged 20-59 y) who maintained the same insurance type (self-employed or employee insurance) for ≥3 years (at least 2008-2010) were recruited for this study and monitored until death or December 2021-whichever occurred first. The primary outcome was all-cause mortality. The secondary outcomes were ischemic heart disease, ischemic stroke, cancer, and hospitalization with a mental illness. Age-standardized cumulative incidence rates were estimated through an indirect method involving 5-unit age standardization. A multivariable Cox proportional hazards model was used to estimate the adjusted hazard ratio (HR) and 95% CI for each sex stratum. Subgroup analyses and an analysis of the effect modification of health checkup participation were also performed. Results: A total of 11,652,716 participants were analyzed (follow-up: median 10.92, IQR 10.92-10.92 y; age: median 42, IQR 35-50 y; male: n=7,975,116, 68.44%); all-cause mortality occurred in 1.27% (99,542/7,851,282) of employees and 3.29% (124,963/3,801,434) of self-employed individuals (P<.001). The 10-year cumulative incidence rates of all-cause mortality differed significantly by employment status (1.1% for employees and 2.8% for self-employed individuals; P<.001). The risk of all-cause mortality was significantly higher among the self-employed individuals when compared with that among employees, especially among female individuals, according to the final model (male: adjusted HR 1.44, 95% CI 1.42-1.45; female: adjusted HR 1.89, 95% CI 1.84-1.94; P<.001). The risk of the secondary outcomes, except all types of malignancies, was significantly higher among the self-employed individuals (all P values were <.001). According to subgroup analyses, this association was prominent in younger individuals with lower incomes who formed a part of the nonparticipation groups. Furthermore, health checkup participation acted as an effect modifier for the association between employment status and all-cause mortality in both sexes (male: relative excess risk due to interaction [RERI] 0.76, 95% CI 0.74-0.79; female: RERI 1.13, 95% CI 1.05-1.21). Conclusions: This study revealed that self-employed individuals face higher risks of all-cause mortality, cardio-cerebrovascular diseases, and mental illnesses when compared to employees. The mortality risk is particularly elevated in younger, lower-income individuals who do not engage in health checkups, with health checkup nonparticipation acting as an effect modifier for this association.

Characteristic features of late-onset systemic lupus erythematosus: An observational study of data from the Lupus Registry of Nationwide Institutions.

OBJECTIVE: Late-onset systemic lupus erythematosus (LoSLE) is known to possess characteristics different from those of early-onset SLE (EoSLE), thereby making their diagnosis difficult. This study aimed to assess the characteristic features of LoSLE in Japan, a model country with a super-aged society. METHODS: Data were obtained from the Lupus Registry of Nationwide Institutions, which includes a multicenter cohort of patients with SLE in Japan who satisfied the 1997 American College of Rheumatology revised classification criteria for SLE. Data were compared between patients with LoSLE (≥50 years old at onset) and EoSLE (<50 years old at onset). To identify factors associated with LoSLE, binary logistic regression was used for the multivariate analysis, and missing values were complemented by multiple imputations. We also conducted a sub-analysis for patients diagnosed within 5 years of onset. RESULTS: Out of 929 enrolled patients, 34 were excluded owing to a lack of data regarding onset age. Among the 895 remaining patients, 100 had LoSLE, whereas 795 had EoSLE. The male-to-female ratio was significantly higher in the LoSLE group than in the EoSLE group (0.32 vs 0.11, p < 0.001). With respect to SLEDAI components at onset, patients with LoSLE exhibited a higher frequency of myositis (11.9% vs 3.75%, p = 0.031), lower frequency of skin rash (33.3% vs 67.7%, p < 0.001), and lower frequency of alopecia (7.32% vs 24.7%, p = 0.012). No significant differences in overall disease activity at onset were observed between the two groups. Regarding medical history, immunosuppressants were more commonly used in EoSLE. A multivariate analysis revealed that a higher male proportion and a lower proportion of new rash at onset were independent characteristic features of LoSLE. We also identified late onset as an independent risk factor for a high SDI score at enrollment and replicated the result in a sub-analysis for the population with a shorter time since onset. CONCLUSIONS: We clarified that LoSLE was characterized by a higher male proportion, a lower frequency of skin rash and a tendency to organ damage. Now that the world is faced with aging, our results may be helpful at diagnosis of LoSLE.

Trends in hospitalisations for lower respiratory infections after the COVID-19 pandemic in France.

OBJECTIVES: We aimed to evaluate the impact of the pandemic and post-pandemic periods on hospital admissions for LRTI, with a focus on patients with chronic respiratory disease (CRD). METHODS: From July 2013 to June 2023, monthly numbers of adult hospitalisations for LRTI (excluding SARS-CoV-2) were extracted from the French National Hospital Discharge Database. They were modelled by regressions with autocorrelated errors. Three periods were defined: (1) early pandemic and successive lockdowns; (2) gradual lifting of restrictions and widespread SARS-CoV-2 vaccination; (3) withdrawal of restriction measures. RESULTS: Pre-pandemic incidence was 96 (90.5 to 101.5) per 100,000 population. Compared with the pre-pandemic period, no more seasonality and significant reductions were estimated in the first two periods: -43.64% (-50.11 to -37.17) and -32.97% (-39.88 to -26.05), respectively. A rebound with a positive trend and a seasonal pattern was observed in period 3. Similar results were observed for CRD patients with no significant difference with pre-pandemic levels in the last period (-9.21%; -20.9% to 1.67%), albeit with differential changes according to the type of CRD. CONCLUSIONS: COVID-19 pandemic containment measures contributed to changes in LRTI incidence, with a rapid increase and return to a seasonal pattern after their lifting, particularly in patients with CRD.

Robot-assisted vs. laparoscopic right hemicolectomy in octogenarians and nonagenarians: an analysis of the US nationwide inpatient sample 2005-2018.

BACKGROUND: Colorectal cancer (CRC) is a significant health concern, particularly among older adults. Outcomes between laparoscopic and robot-assisted surgeries for right-sided colon cancers in the oldest old population have yet to be evaluated despite increased use of these surgeries. AIM: This study aimed to compare clinical outcomes after robot-assisted right hemicolectomy (RARH) versus laparoscopic right hemicolectomy (LRH) in octogenarian and nonagenarian patients. METHODS: This population-based, retrospective and observational study analyzed the data of adults ≥ 80 years old diagnosed with right-side colon cancer who received RARH or LRH. All data were extracted from the US National Inpatient Sample (NIS) database 2005-2018. Associations between type of surgery and in-hospital outcomes were determined using univariate and multivariable logistic regression and linear regression analysis. RESULTS: Data of 7,550 patients (representing 37,126 hospitalized patients in the U.S.) were analyzed. Mean age of the study population was 84.8 years, 61.4% were females, and 79.1% were non-smokers. After adjusting for relevant confounders, regression analysis showed that patients undergoing RARH had a significantly shorter LOS (adjusted Beta (aBeta), -0.24, 95% CI: -0.32, -0.15) but greater total hospital costs (aBeta, 26.54, 95% CI: 24.64, 28.44) than patients undergoing LRH. No significant differences in mortality, perioperative complications, and risk of unfavorable discharge were observed between the two procedures (p > 0.05). Stratified analyses by frailty status revealed consistent results. CONCLUSIONS: RARH is associated with a significantly shorter LOS but higher total hospital costs than LRH among octogenarians and nonagenarians. Other short-term outcomes for this population are similar between the two procedures, including in-hospital mortality, perioperative complications, and unfavorable discharge. These findings also apply to frail patients.

Acromegaly: Incidence, Patient Characteristics And Treatment Patterns In A 10-Year Nationwide Retrospective Hospital Cohort Study.

INTRODUCTION: Acromegaly is a multisystemic disease associated with numerous comorbidities, notably cardiovascular disease and cancer. The objective of our study was to estimate the contemporary prevalence and incidence of acromegaly and its complications in a nationwide French retrospective cohort. METHODS: First, the positive predictive value of the ICD-10 acromegaly code E22.0 was checked by individually reviewing 132 medical records from one teaching hospital. Second, to estimate the prevalence of acromegaly, data of patients hospitalized between 2012 and 2021 were extracted from the PMSI French hospital database, using the dedicated ICD-10 code. Third, in a 2015-2020 subset cohort, we estimated the incidence of acromegaly, prevalence of complications and risk ratios of associated comorbidities or complications in subgroups of interest. RESULTS: A total of 7,943 adult patients were identified, with a positive predictive value of 87%, resulting in a prevalence of 10.4/100,000 in France. Annual incidence was 0.76/100,000. The most frequent complications were hypertension (43%), sleep apnea (34.3%) and diabetes (31.3%), mostly with onset before diagnosis. Patients with diabetes were at higher risk for most comorbidities: myocardial infarction (odds ratio (OR) 3.14 [1.92-5.13]), ischemic stroke (1.64 [1.18-2.28]) and cancer of any type (1.53 [1.27-1.84]). These risks were partially attenuated after adjustment for other cardiovascular risk factors, becoming respectively 1.52 [0.89-2.59], 0.92 [0.64-1.33] and 1.09 [0.88-1.34]. Treatment involved pituitary surgery in 43% and radiotherapy in 4.6% of patients. CONCLUSION: This study was the first, in a large population, to estimate the contemporary incidence and prevalence of acromegaly in non-selected patients at nationwide level in France. We found higher prevalences of complications than previously reported in tertiary specialized expert centers, probably reflecting suboptimal management in non-selected hospitals, whether specialized or not.

Impact of frailty on outcomes and readmissions after transcatheter and surgical aortic valve replacement in a national cohort.

Objective: We examined the effect of frailty on in-hospital mortality, readmission rates, and hospitalization costs after transcatheter and surgical aortic valve replacement in a population-level cohort. Methods: The Nationwide Readmissions Database was queried for patients who underwent transcatheter or surgical aortic valve replacement during 2016-2018. Multivariate logistic regression was used to discern independent effects of frailty on outcomes. Kaplan-Meier time-to-event analysis was used to evaluate the effect of frailty on freedom from readmission. Results: A total of 243,619 patients underwent aortic valve replacement: 142,786 (58.6%) transcatheter aortic valve replacements and 100,833 (41.4%) surgical aortic valve replacements. Frail patients constituted 16,388 (11.5%) and 7251 (7.2%) in the transcatheter aortic valve replacement and surgical aortic valve replacement cohorts, respectively. Compared with nonfrail patients, frail patients had greater in-hospital mortality (transcatheter aortic valve replacement: 3.2% vs 1.1%; surgical aortic valve replacement: 6.1% vs 2.0%; both P < .001), longer length of stay (transcatheter aortic valve replacement: 4 vs 2 days; surgical aortic valve replacement: 13 vs 6 days; P < .001), and greater cost (transcatheter aortic valve replacement: $51,654 vs $44,401; surgical aortic valve replacement: $60,782 vs $40,544; P < .001). Time-to-event analysis showed that frail patients had higher rates of readmission over the calendar year in both transcatheter aortic valve replacement (P < .001) and surgical aortic valve replacement (P < .001) cohorts. This association persisted on adjusted multivariate regression for mortality (transcatheter aortic valve replacement odds ratio [95% CI] 1.98 [1.65-2.37], surgical aortic valve replacement 1.96 [1.60-2.41]), 30-day readmission (transcatheter aortic valve replacement 1.38 [1.27-1.49], surgical aortic valve replacement 1.47 [1.30-1.65]), and 90-day readmission (transcatheter aortic valve replacement 1.41 [1.31-1.52], surgical aortic valve replacement 1.60 [1.43-1.79]) (P < .001 for all). Conclusions: For patients undergoing transcatheter or surgical aortic valve replacement, frailty is associated with in-hospital mortality, readmission, and higher costs. Further efforts to optimize outcomes for frail patients are warranted.

The epidemiology of geriatric fractures: A nationwide analysis of 1 million fractures.

OBJECTIVE: Fractures among the geriatric population impose a substantial burden on healthcare systems. This study aims to investigate the incidence and distribution of fractures among geriatric individuals over seven years, analyzing changes by age and sex. The findings will inform national healthcare strategies for addressing the growing impact of geriatric fractures. MATERIALS AND METHODS: Electronic health records from a nationwide personal health records system were analyzed, focusing on ICD-10 codes for fractures. Recurrent codes for the same patients within three months were excluded. Patients were categorized into three age groups (65-74, 75-84, and 85+ years), and fractures were grouped anatomically. Incidence rates for specific fracture locations were calculated based on the actual population at risk annually. Incidence rates were further stratified by sex and age groups using Turkey's age- and sex-specific populations. RESULTS: A total of 1,004,663 geriatric fractures (66.9 % female, 33.1 % male) were identified over seven years. The overall fracture incidence among the geriatric population was 1.9 % (1910/100,000). Hip fractures were the most common (25.2 %), followed by wrist (15 %) and lumbar-pelvic fractures (11.9 %). Femur fractures were predominant in the 75-84 and 85+ age groups, while wrist fractures were more common in the 65-74 age group. Fracture incidences generally increased with age, except for ankle, foot, and toe fractures, which decreased with age for both sexes (p < 0.05). The male/female ratio was lowest for wrist, elbow, and humeral shaft fractures (1:3.2, 1:2.7, and 1:2.7, respectively). The lowest overall fracture incidence was observed in 2020 (1568/100,000), while the highest was in 2017 (2523/100,000). CONCLUSION: With Turkey's aging population, the socioeconomic impact of geriatric fractures is anticipated to rise. Fracture patterns and incidence vary by age and sex among geriatric individuals. These findings provide valuable insights for healthcare planning and the development of community-based preventive measures tailored to specific fracture locations and demographics.

Bidirectional association between inflammatory bowel disease and type 1 diabetes: a nationwide matched cohort and case-control study.

Background: Co-occurrence of inflammatory bowel disease (IBD) and type 1 diabetes (T1D) has been linked to poor clinical outcomes, but evidence on their bidirectional associations remain scarce. This study aims to investigate their bidirectional associations. Methods: A nationwide matched cohort and case-control study with IBD patients identified between 1987 and 2017. The cohort study included 20,314 IBD patients (≤28 years; Crohn's disease [CD, n = 7277], ulcerative colitis [UC, n = 10,112], and IBD-unclassified [IBD-U, n = 2925]) and 99,200 individually matched reference individuals, with a follow-up until December 2021. The case-control study enrolled 87,001 IBD patients (no age restriction) and 431,054 matched controls. We estimated adjusted hazard ratio (aHR) of incident T1D in the cohort study with flexible parametric survival model and adjusted odds ratio (aOR) of having a prior T1D in the case-control study with conditional logistic regression model, with 95% confidence intervals (CI). Findings: During a median follow-up of 14 years, 116 IBD patients and 353 reference individuals developed T1D. Patients with IBD had a higher hazard of developing T1D (aHR = 1.58 [95% CI = 1.27-1.95]). The hazard was increased in UC (aHR = 2.02 [1.51-2.70]) but not in CD or IBD-U. In the case-control study, a total of 1018 (1.2%) IBD patients and 3496 (0.8%) controls had been previously diagnosed with T1D. IBD patients had higher odds of having prior T1D (aOR = 1.36 [1.26-1.46]). Such positive association was observed in all IBD subtypes. The sibling comparison analyses showed similar associations between IBD and T1D (aHR = 1.44 [0.97-2.15] and aOR = 1.32 [1.18-1.49]). Interpretation: Patients with IBD had a moderately increased hazard of developing T1D and higher odds of having prior T1D. Their bidirectional associations may be partially independent of shared familial factors.

Impact of SARS-CoV-2 infection on short-term postoperative outcomes after gastroenterological cancer surgery using data from a nationwide database in Japan.

Background: Due to the coronavirus disease 2019 (COVID-19) pandemic, cancer screening, diagnosis, and treatment have changed. This study aimed to investigate the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection prior to gastroenterological cancer surgeries on postoperative complications using data from a nationwide database in Japan. Methods: Data on patients who underwent surgery for cancer including esophageal, gastric, colon, rectal, liver, and pancreatic cancer between July 1, 2019, and September 300, 2022, from real-world sources in Japan were analyzed. The association between preoperative SARS-CoV-2 infection and short-term postoperative outcomes was evaluated. A similar analysis stratified according to the interval from SARS-CoV-2 infection to surgery (<4 vs. >4 weeks) was conducted. Results: In total, 60 604 patients were analyzed, and 227 (0.4%) patients were diagnosed with SARS-CoV-2 infection preoperatively. The median interval from SARS-CoV-2 infection to surgery was 25 days. Patients diagnosed with SARS-CoV-2 infection preoperatively had a significantly higher incidence of pneumonia (odds ratio: 2.05; 95% confidence interval: 1.05-3.74; p = 0.036) than those not diagnosed with SARS-CoV-2 infection based on the exact logistic regression analysis adjusted for the characteristics of the patients. A similar finding was observed in patients who had SARS-CoV-2 infection <4 weeks before surgery. Conclusions: Patients with a history of SARS-CoV-2 infection had a significantly higher incidence of pneumonia. This finding can be particularly valuable for countries that have implemented strict regulations in response to the COVID-19 pandemic and have lower SARS-CoV-2 infection-related mortality rates.

Vascular disease and risk of fall-related injuries in Parkinson's disease: A nationwide cohort study in Sweden.

INTRODUCTION: Parkinson's disease (PD) patients are prone to fall and fall-related injuries (FI). Vascular disease is common in PD and is positively associated with falls in elderly. We aimed to evaluate the association of vascular disease with FI risk in PD. METHODS: A nationwide cohort study of patients with primary PD diagnosis in Sweden was performed using Swedish national registers. Patients with and without vascular disease were followed from PD diagnosis until subsequent FI or 2013-12-31. The association of vascular disease with FI risk was estimated as hazard ratio (HR) and 95 % confidence interval (CI) by Cox regression using attained age as underlying timescale. RESULTS: We identified 2734 and 6979 incident FI from 8025 PD patients with and 20,543 without vascular disease, respectively. Overall, vascular disease associated positively with subsequent FI, which was mainly driven by the significant risk elevation within the first 6 months following vascular disease (HR < 0.5year [95 % CI] for PD diagnosed ≤75 years is 1.61 [1.39-1.87] and for PD diagnosed >75 years is 1.48 [1.32-1.65]). Thereafter, the association attenuated to null before it rebounded five years after exposure in PD diagnosed ≤75 years (HR > 5year = 1.26, 95 % CI: 1.10-1.45); whereas for PD diagnosed >75 years, it dropped remarkably and remained non-significant 6 months after exposure. When vascular disease was restricted to stroke, we saw a similar temporal pattern except that the short-term HRs among younger patients were stronger, lasted longer, and declined continuously without rebound. CONCLUSIONS: Fall prevention is crucial to PD patients immediately after a vascular event.

Permanent pacemaker implantation after combined mitral- and tricuspid valve surgery-a nationwide multicentre study.

OBJECTIVES: The threshold to perform concomitant TV repair (TVr) during primary mitral valve (MV) surgery has decreased, based on recent randomized evidence. Based on these developments, the indication for TVr during MV surgery is expected to increase further. However, concerns have been raised regarding the risk of permanent pacemaker implantation (PPI) during a concomitant procedure. Therefore, we aim to assess the incidence of PPI in combined MV and TV surgery in a nationwide registry. METHODS: The current study uniquely cross-linked the Cardiothoracic and Pacemaker/ICD registry of the Netherlands Heart Registration. Patients undergoing primary MV and TV surgery (± ASD closure, rhythm surgery, CABG) between January 1st-December 31st 2021 were included. The primary outcome was PPI within 30 days after surgery. Subgroup analyses were performed for isolated MV and TV surgery and MV repair. The association between concomitant TV surgery and PPI was assessed using multivariable binary logistic regression analyses. RESULTS: A total of 1060 patients (n = 833 MV, n = 227 MV+TV) were included. The overall incidence of PPI was 4.3%. No significant difference in PPI between MV and MV+TV surgery were found (3.7% vs 6.6%, P = 0.06). Concomitant TV surgery was not an independent risk factor for PPI after surgery after adjustment for covariates. These results were robust across subgroup and sensitivity analyses. CONCLUSIONS: The current study was not able to find a statistical difference between the PPI rate in MV surgery patients and MV + TV surgery patients. Extension of the waiting period prior to PPI, may result in decreased PPI rates.

Association of rheumatoid arthritis with age-related macular degeneration in nationwide longitudinal cohort study.

Previous studies on the association between age-related macular degeneration (AMD) and rheumatoid arthritis (RA) have shown conflicting results. We sought to assess the association between AMD with/without visual disability (VD) and the risk of RA using National Health Insurance data in South Korea. In total, 3,537,293 individuals who underwent health checkups in 2009 were included and followed until 2019. Participants with VD were defined as those with loss of vision or a visual field defect as certified by the Ministry of Health and Welfare of Korea. Using multivariable adjusted Cox regression analysis, RA hazard ratios were estimated for control and AMD with/without VD groups. In total, 43,772 participants (1.24%) were diagnosed with RA. Individuals with AMD were at higher risk of RA compared to controls, regardless of the presence of VD (aHR 1.11; 95% CI 1.02-1.21). Among individuals with AMD, different risk levels of RA were observed between those without VD (aHR 1.13; 95% CI 1.03-1.21) and those with VD (aHR 0.90; 95% CI 0.64-1.27). AMD was associated with a higher risk of RA, which remained significant as a trend even after adjusting for lifestyle factors and comorbidities.

Anxiety and depression as risk factors for postoperative complications and pain in lumbar spine surgery: A national database study.

Objective: To investigate the potential association between anxiety and depression and surgical outcomes in patients undergoing LSS. By analyzing data from the Nationwide Inpatient Sample (NIS) database, we aim to identify whether anxiety and depression serve as predictors for postoperative complications and pain-related symptoms. Methods: A retrospective analysis was conducted via the NIS database. Those undergoing LSS from 2010 to 2019 were divided into four groups: those with a diagnosis of anxiety, depression, both depression and anxiety, and neither depression nor anxiety. The chi-squared test, rank sum test, the Student-Newman-Keuls, least significant difference, and Bonferroni tests were used to identify differences between these groups. Logistic regression analysis was utilized to determine if anxiety and depression were predictors for postoperative complications and pain-related symptoms. Results: From 2010 to 2019, 832,099 patients undergoing LSS were identified. Patients with either anxiety or depression were associated with heavier economic burdens ($85,375, $76,840, $88,542 in the anxiety, depression, and comorbid group, respectively, p < 0.001) and prolonged hospital stay (p < 0.001). They were identified to experience higher risks of various complications especially thrombophilia (OR = 1.82, and 1.55 in the anxiety and the depression group, respectively, p < 0.01). Multiple pain-related symptoms, but face reduced risks of inpatient mortality (OR = 0.71, 0.75, and 0.63 in the anxiety, depression, and comorbid group, respectively, p < 0.01). Conclusions: The overall morbidities of depression and anxiety were relatively high. Psychiatric comorbidities were closely correlated with the negative outcomes after LSS. The psychological health of patients receiving LSS requires necessary attention to ensure pain control and prevent complications postoperatively.
