Background and aims Pancreatic walled-off necrosis (WON) carries significant mortality and morbidity risks, often necessitating intensive care unit (ICU) admission. This retrospective study aimed to evaluate whether routine biochemical parameters at the time of the index endoscopic procedure could predict ICU admission and 1-year mortality following endoscopic treatment of WON. Materials and Methods We retrospectively identified 201 consecutive patients who underwent endoscopic drainage for WON between January 1, 2010, and December 31, 2020. Associations between routine biochemical blood tests and outcomes were assessed using logistic regression models. Results Within 1 year of the index endoscopy, 31 patients (15.4%) died, and 40 (19.9%) were admitted to the ICU due to sepsis. Preoperative electrolyte disturbances were more prevalent among ICU-admitted patients and nonsurvivors. Hyperkalemia, hypoalbuminemia, and elevated urea were significant predictors of 1-year mortality, while hypernatremia, elevated serum creatinine, and hypoalbuminemia predicted ICU admission. Predictive models exhibited good discriminative ability, with an AUC of 0.84 (95% CI,0,75–0.93) for 1-year mortality and 0.86 (95%CI, 0.79–0.92) for ICU admission. Conclusions Preoperative imbalances in routine blood tests effectively predict adverse outcomes in endoscopically treated WON patients., Background and aims Pancreatic walled-off necrosis (WON) carries significant mortality and morbidity risks, often necessitating intensive care unit (ICU) admission.

Background: Caregiving in Alzheimer’s disease (AD) is often provided by informal care partners, who spend more hours per week on average than care partners of individuals with conditions other than AD. The burden of care in partners of individuals with AD is not well understood, and a comparison between AD and multiple chronic diseases is yet to be presented. Objective: The current study aims to compare the care partner burden of AD to that of other chronic diseases through a systematic literature review. Methods: This study aimed to identify relevant data on care partner burden for AD and other chronic diseases. Data was collected from journal articles published in the last ten years, using two unique search strings on PubMed, and analysed using pre-defined patient-reported outcome measures (PROMs) including the EQ-5D-5L, GAD-7, GHQ-12, PHQ-9, WPAI and the ZBI. The data was grouped according to the used PROMs and the diseases studied, and the number of participants in the studies reporting burden of caregiving in AD was adjusted to reflect the number of participants in studies reporting care partner burden in other chronic diseases. Results: All results in this study are reported as a mean value and standard deviation (SD). The ZBI measurement was the most used PROM to collect care partner burden (15 studies) and showed a moderate burden (mean: 43.88, SD: 18.35) on care partners of individuals with AD, higher than most of the other included diseases (mean range: [0.77, 37.43]) except for those characterized psychiatric symptoms (mean range: [55.92, 59.11]). Other PROMs such as PHQ-9 (6 studies) and GHQ-12 (4 studies) showed greater burden on care partners of individuals with other chronic diseases such as heart failure, hematopoietic cell transplantations, cancer and depression compared to AD. Likewise, GAD-7 and EQ-5D-5L measurements showed a lesser burden on care partners of individuals with AD compared to care partners of individuals with anxiety, ca

OBJECTIVES: In patients with chronic pancreatitis, pancreatic duct leakage is associated with a prolonged disease course and serious complications. We aimed to assess the efficacy of this multimodal treatment of pancreatic duct leakage.METHODS: In a retrospective design, patients with chronic pancreatitis, an amylase content greater than 200 U/L in either ascites or pleural fluid and treated between 2011 and 2020, were evaluated. The primary end point was treatment success.RESULTS: Twenty-seven patients (22 males, median age 60, median American Society of Anesthesiologists score 3) were included.Endoscopic retrograde pancreatography was performed in 23 patients (85%) with transpapillary stenting of the main pancreatic duct in 22 patients (96%). Pancreatic sphincterotomy and dilation of the main pancreatic duct were done in 14 patients (61%) and 17 patients (74%), respectively. Twelve patients (44%) were treated with somatostatin analogs, parenteral nutrition, and were "nil by mouth" for a median of 11 days (range, 4-34 days). Six patients (22%) had extracorporeal shock wave lithotripsy due to pancreatic duct stones. One patient (4%) was referred for surgery. All 23 patients (100%) were treated with success after a median of 21 days (range, 5-80 days).CONCLUSIONS: Multimodal treatment of pancreatic duct leakage is effective, with minimal need for surgery.

The aim of this study was to assess the possible association between P-Mg and subsequent high levels of HbA1c. The study involves data from primary health care patients and data from patients treated in hospitals located in the capital region of Denmark. P-Mg and HbA1c levels were analyzed from 121,575 patients in the period 2010–2022. Patients were categorized in a diabetic and non-diabetic group. Out of 121,575 patients, 8,532 were categorized as diabetic. A reverse J-shaped association between P-Mg and HbA1c levels ≥ 48 mmol/mol was observed with nadir at P-Mg of 0.90 mmol/L. The unadjusted hazard ratio (HR) for having a first HbA1c measurement ≥ 48 mmol/mol is 1.54 (95% Cl 1.50; 1.57) per 0.1 mmol/L decrease in P-Mg when P-Mg is lower than 0.90 mmol/L. After adjusting for age and gender, the HR remained significant at 1.45 (95% Cl 1.41; 1.48). For P-Mg levels above 0.90 mmol/L, the unadjusted HR per 0.1 mmol/L increase in P-Mg was 1.04 (95% Cl 1.02; 1.06). After adjusting for age and gender the HR remained significant at 1.06 (95% Cl 1.05; 1.08). In conclusion, this study found that patients with dysmagnesemia have a higher risk of developing diabetes even after adjusting for age and gender. Hyper- or hypomagnesemia in patients could be a biomarker for predicting the risk of developing diabetes.

Vitamin D was investigated as a prognostic biomarker in COVID-19, in relation to both disease susceptibility and outcomes in infected individuals. Patients admitted to the hospital with a confirmed COVID-19 diagnosis were included if they had a vitamin D measurement prior to hospitalization. Using age- and sex-matched controls, vitamin D levels were investigated for an association with COVID-19 related hospitalizations. Further, vitamin D levels were investigated for an association with 30-day mortality in hospitalized COVID-19 patients. Additionally, three meta-analyses were conducted, investigating the association of vitamin D with the following outcomes: Having a positive SARS-CoV-2 test, hospitalization with COVID-19, and mortality in COVID-19 patients. A total of 685 hospitalized COVID-19 patients were included in the single-center study. Compared to controls, they had higher vitamin D levels. Unadjusted analysis of these 685 cases found higher vitamin D levels associated with increased 30-day mortality. This association disappeared after adjusting for age. In the fully adjusted model, no association between vitamin D and 30-day mortality was found. The meta-analyses found significant associations between lower vitamin D and having a positive SARS-CoV-2 test, and mortality among hospital-admitted COVID-19 patients. The relationship between lower vitamin D and COVID-19 related hospital admissions trended towards being positive but was not statistically significant. Many factors seem to influence the associations between vitamin D and COVID-19 related outcomes. Consequently, we do not believe that vitamin D in and of itself is likely to be a clinically useful and widely applicable predictor for the susceptibility and severity of COVID-19 infections.

Introduction: Approximately 25% of the patients with hospital acquired anemia (HAA) develop moderate to severe HAA during hospitalization. This is related to an increased risk of prolonged stay, readmission and mortality. The primary aim was during one year to characterize a population with very frequent phlebotomies based on a university hospital in the Capital Region of Denmark and the related general practitioners Material and methods: We conducted a retrospective cohort study using administrative data on phlebotomies from 1 January 2019 to 31 December 2019 analyzed at a university hospital. Results: A total of 203,811 patients had 10,083,207 requisitions and 1,373,013 tubes. One percent, 1985 patients, had an extreme of frequent phlebotomies >60 tubes and formed the basis for the study population. The study population was significantly older as compared to the excluded patients (<60 tubes) (mean 65.7 vs. 51.6 years, p <.001).The likelihood of hemoglobin decrease per 100 mL blood drawn were calculated at four levels of decreases: Hemoglobin decrease of 2 mmol/L (adjusted OR; 95%; 2.03, CI 1.79–2.31), hemoglobin decrease of 3 mmol/L (adjusted OR; 95%, 1.36, CI 1.28–1.45), hemoglobin decrease of 4 mmol/L, (adjusted OR; 95%, 1.27, CI 1.19–1.35) and hemoglobin decrease of 5 mmol/L, (adjusted OR; 95% 1.22, CI 1.13–1.31). Conclusions: Moderate to severe HAA occurred in a limited group with excessive many phlebotomies. It was a worrisome trend that the frailest patients had the highest risk of developing HAA.

It has recently been hypothesized that vitamin K could play a role in COVID-19. We aimed to test the hypotheses that low vitamin K status is a common characteristic of patients hospitalized with COVID-19 compared to population controls and that low vitamin K status predicts mortality in COVID-19 patients. In a cohort of 138 COVID-19 patients and 138 population controls, we measured plasma dephosphorylated-uncarboxylated Matrix Gla Protein (dp-ucMGP), which reflects the functional vitamin K status in peripheral tissue. Forty-three patients died within 90 days from admission. In patients, levels of dp-ucMGP differed significantly between survivors (mean 877; 95% CI: 778; 995) and non-survivors (mean 1445; 95% CI: 1148; 1820). Furthermore, levels of dp-ucMGP (pmol/L) were considerably higher in patients (mean 1022; 95% CI: 912; 1151) compared to controls (mean 509; 95% CI: 485; 540). Cox regression survival analysis showed that increasing levels of dp-ucMGP (reflecting low vitamin K status) were associated with higher mortality risk (sex-and age-adjusted hazard ratio per doubling of dp-ucMGP was 1.49, 95% CI: 1.03; 2.24). The association attenuated and became statistically insignificant after adjustment for co-morbidities (sex, age, CVD, diabetes, BMI, and eGFR adjusted hazard ratio per doubling of dp-ucMGP was 1.22, 95% CI: 0.82; 1.80). In conclusion, we found that low vitamin K status was associated with mortality in patients with COVID-19 in sex-and age-adjusted analyses, but not in analyses additionally adjusted for co-morbidities. Randomized clinical trials would be needed to clarify a potential role, if any, of vitamin K in the course of COVID-19.

Background: In hospitalized patients, abnormal plasma electrolyte concentrations are frequent and have been linked to poor outcomes following acute surgery. The aim of this study was to assess whether preoperative plasma levels of potassium, sodium, and creatinine at the time of admission were associated with 30-day mortality in patients following open abdominal surgery. Methods: This was a single-center register-based retrospective study. By means of electronic search in a maintained surgery database, all patients (n = 4177) aged ≥ 60 years old undergoing open surgery in our department from January 2000 to May 2013 were identified. Plasma was assessed within 30 days prior to surgery. The primary endpoint was 30-day postoperative mortality. The association between mortality and plasma levels of potassium, sodium, and creatinine were examined using Cox proportional hazard models. Results: A total of 3690 patients were included in the study cohort. The rates of abnormal preoperative plasma levels were 36, 41, and 38% for potassium, sodium, and creatinine, respectively. The overall 30 day mortality was 20%. A predictive algorithm for 30 day mortality following abdominal surgery was constructed by means of logistic regression showing excellent distinction between patients with and without a fatal postoperative outcome. Conclusion: Apart from demographic factors (age, sex, and emergency surgery), preoperative imbalance in potassium, sodium and creatinine levels were significant independent predictors of early mortality following open abdominal surgery.

BACKGROUND: Cardiovascular disease remains the most prevalent cause of death in hyperthyroidism. However, the impact on cardiovascular events of varying thyroid status and of treatment remains unclarified. The aims of this study were to investigate the association between hyperthyroidism and cardiovascular events in treated and untreated hyperthyroid individuals, as well as exploring the impact of cumulative periods of hyperthyroidism as a proxy for undertreatment on cardiovascular events.METHOD: This was a case-control study nested within a population-based cohort of individuals attending health services in Funen County, Denmark, in the period from 1995 to 2011. Data on comorbidities and mortality were collected from The Danish National Patient Register and The Danish Register of Causes of Death. Participants were 275,467 individuals with at least one serum thyrotropin (TSH) measurement in the study period. Hyperthyroidism was defined as at least two measurements of decreased serum TSH within six months, separated by at least 14 days. Incident cases of cardiovascular disease (myocardial infarction, atrial fibrillation, heart failure, stroke, and cardiovascular death) were matched with controls. Conditional logistic regression analyses were performed to calculate odds ratios (OR) for exposure to hyperthyroidism, adjusting for preexisting comorbidities.RESULTS: A total of 20,651 individuals experienced a cardiovascular event (9.5% incidence rate 13.2/1000 person-years [confidence interval (CI) 13.0-13.4]) compared to euthyroid individuals, conditional logistic regression showed increased cardiovascular risk in untreated hyperthyroid patients (OR = 1.25 [CI 1.06-1.48], p = 0.007) but not in treated hyperthyroid patients (OR = 1.04 [CI 0.90-1.22], p = 0.57)]. The OR for cardiovascular events per six months of decreased TSH was 1.09 ([CI 1.05-1.14], p < 0.001) in treated hyperthyroid individuals, and 1.10 ([CI 1.05-1.15], p < 0.001) in untreated h

Objective: To investigate the association between hypothyroidism and cardiovascular disease (CVD) in both treated and untreated hypothyroid patients, and the consequences of over- and under-treatment with respect to cardiovascular risk. Design: A registry-based case-control study nested within a population -based cohort of 275 467 individuals with at least one serum thyroid stimulating hormone (TSH) measurement in the period of 1995-2011. Methods: Incident cases of CVD were matched with controls according to gender, age and year of birth. Conditional logistic regression analyses were performed to calculate CVD risks associated with exposure to hypothyroidism, with adjustment for 19 pre-existing comorbidities, including cardiovascular disease and diabetes, using the Charlson Comorbidity Index. Results: Overall, 20 487 individuals experienced CVD (9.4%, incidence r ate 13.1 per 1000 person-years, 95% confidence interval (CI), 13.0-13.3). Risk of CVD was increased in untreated hypothyroidism compared to euthyroidism (odds ratio (OR): 1.83 (95% CI: 1.43-2.35; P < 0.001)). Cardiovascular risk was increased in both treated and untreated hypothyroid individuals per half year of elevated TSH (OR: 1.11 (95% CI: 1. 06-1.16; P < 0.001) and OR: 1.15 (95% CI: 1.09-1.23; P = 0.001), respectively). In patients treated with levothyroxine, OR for CVD was 1.12 (95% CI: 1.06-1.18; P < 0.001) for each 6 months of decreased TSH. Conclusion: Cardiovascular risk is increased in untreated, but not in treated hypothyroid patients. Among those with treated hypothyroidism, duration of decreased TSH (overtreatment) had a similar impact on cardiovascular risk as duration of elevated TSH (under-treatment), highlighting the importance of initiating treatment and maintaining biochemical euthyroidism in hypothyroid patients in order to reduce the risk of CVD and death.

Vitamin D has been linked to cancer development in both pre-clinical and epidemiological studies. Our study examines the association between serum levels of vitamin D and cancer incidence in the Capital Region of Denmark. Individuals who had vitamin D analyzed at The Copenhagen General Practitioners Laboratory between April 2004 and January 2010 were linked to Danish registries with end of follow-up date at Dec 31st 2014, excluding individuals with pre-existing cancer. Cox regression models adjusted for age in one-year intervals, sex, month of sampling, and Charlson Comorbidity Index were applied. The study population of 217,244 individuals had a median vitamin D level of 46 nmol/L (IQR 27–67 nmol/L). Non-melanoma skin cancer was the most frequent form of cancer, followed by breast-, lung-, and prostate cancers. No associations were found between increments of 10 nmol/L vitamin D and incidence of breast, colorectal, urinary, ovary or corpus uteri cancer. However, higher levels of vitamin D were associated with higher incidence of non-melanoma (HR 1.09 [1.09–1.1]) and melanoma skin cancer (HR 1.1 [1.08–1.13]) as well as prostate (HR 1.05 [1.03–1.07]) and hematological cancers (HR 1.03 [1.01–1.06]), but with lower incidence of lung cancer (HR 0.95 [0.93–0.97]). In our study, vitamin D levels are not associated with the incidence of several major cancer types, but higher levels are significantly associated with a higher incidence of skin, prostate, and hematological cancers as well as a lower incidence of lung cancer. These results do not support an overall protective effect against cancer by vitamin D.
