Patients with COPD have a higher risk of type 2 diabetes compared with control subjects after adjusting for confounding factors such as sex, age, residential area, insurance premium, steroid use, hypertriglycemia, hypertension, CAD and cerebrovascular disease. Continuous surveillance of signals of dysglycemia may be incorporated into care programmes for patients with COPD.
Abundances of study in different population have noted that obese cardiovascular disease (CVD) patients have a better prognosis than leaner patients, which refer to the phenomenon of obesity paradox. However, data on the association between body mass index (BMI) and mortality among Asian patients are limited, especially in patients with type 2 diabetes mellitus (T2DM). We investigate the association between BMI and all-cause mortality in Taiwanese patients with T2DM to define the optimal body weight for health.We conducted a longitudinal cohort study of 2161 T2DM patients with a mean follow-up period of 66.7 ± 7.5 months. Using Cox regression models, BMI was related to the risk of all-cause mortality after adjusting all confounding factors.A U-shaped association between BMI and all-cause mortality was observed among all participants. Those with BMIs <22.5 kg/m2 had a significantly elevated all-cause mortality as compared with those with BMIs 22.5 to 25.0 kg/m2, (BMIs 17.5–20.0 kg/m2: hazard ratio 1.989, P < 0.001; BMIs 20.0–22.5 kg/m2: hazard ratio 1.286, P = 0.02), as did those with BMIs >30.0 kg/m2 (BMIs 30.0–32.5 kg/m2: hazard ratio 1.670, P < 0.001; BMIs 32.5–35.0 kg/m2: hazard ratio, 2.632, P < 0.001). This U-shaped association remained when we examined the data by sex, age, smoking, and kidney function.Our study found a U-shaped relationship between all-cause mortality and BMI in Asian patients with T2DM, irrespective of age, sex, smoking, and kidney function. BMI <30 kg/m2 should be regarded as a potentially important target in the weight management of T2DM.
ObjectiveTuberculosis continues to be a major global health problem. We wanted to investigate whether Type 2 diabetes was a risk factor for tuberculosis in an Asian population.MethodsFrom Taiwan’s National Health Insurance Research Database, we collected data from 31,237 female patients with type 2 diabetes and 92,642 female controls and 32,493 male patients with type 2 diabetes and 96,977 male controls. Cox proportional hazard regression was performed to evaluate independent risk factors for tuberculosis in all patients and to identify risk factors in patients with type 2 diabetes.ResultsDuring the study period, both female (standardized incidence ratio (SIR): 1.40, p<0.01) and male (SIR: 1.48, p<0.01) patients with type 2 diabetes were found to have a significantly higher rate of incident tuberculosis than the control group. Type 2 diabetes (HR:1.31, 1.23–1.39, p<0.001) was significantly associated with tuberculosis after adjusting sex, age, bronchiectasis, asthma and chronic obstructive lung disease.ConclusionsPatients with type 2 diabetes have a higher risk of tuberculosis compared to control subjects after adjusting for confounding factors. The current diabetes epidemic may lead to a resurgence of tuberculosis in endemic regions. Therefore, preventive measures, including addressing the possibility that type 2 diabetes increase the individual’s susceptibility for incident TB, should be taken to further reduce the incidence of tuberculosis.
Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.
Serum potassium (K+) levels between 3.5 and 5.0 mmol/L are considered safe for patients. The optimal serum K+ level for critically ill patients with acute kidney injury undergoing continuous renal replacement therapy (CRRT) remains unclear. This retrospective study investigated the association between ICU mortality and K+ levels and their variability. Patients aged >20 years with a minimum of two serum K+ levels recorded during CRRT who were admitted to the ICU in a tertiary hospital in central Taiwan between January 01, 2010, and April 30, 2021 were eligible for inclusion. Patients were categorized into different groups based on their mean K+ levels: <3.0, 3.0 to <3.5, 3.5 to <4.0, 4.0 to <4.5, 4.5 to <5.0, and ≥5.0 mmol/L; K+ variability was divided by the quartiles of the average real variation. We analyzed the association between the particular groups and in-hospital mortality by using Cox proportional hazard models. We studied 1991 CRRT patients with 9891 serum K+ values recorded within 24 h after the initiation of CRRT. A J-shaped association was observed between serum K+ levels and mortality, and the lowest mortality was observed in the patients with mean K+ levels between 3.0 and 4.0 mmol/L. The risk of in-hospital death was significantly increased in those with the highest variability (HR and 95% CI = 1.61 [1.13–2.29] for 72 h mortality; 1.39 [1.06–1.82] for 28-day mortality; 1.43 [1.11–1.83] for 90-day mortality, and 1.31 [1.03–1.65] for in-hospital mortality, respectively). Patients receiving CRRT may benefit from a lower serum K+ level and its tighter control. During CRRT, progressively increased mortality was noted in the patients with increasing K+ variability. Thus, the careful and timely correction of dyskalemia among these patients is crucial.
Gattinoni’s equation, $${\text{MP}}_{{{\text{rs}}}} \, = \,0.098\, \times \,{\text{RR}}\, \times \,\left[ {{\text{V}}_{T} ^{2} \left( {\frac{1}{2}{\text{E}}_{{{\text{rs}}}} \, + \,{\text{RR}}\, \times \,\frac{{1\, + \,I:E}}{{60\, \times \,I:E}}\, \times \,{\text{R}}_{{{\text{aw}}}} } \right)\, + \,{\text{V}}_{{\text{T}}} \, \times \,{\text{PEEP}}} \right]$$ MP rs = 0.098 × RR × V T 2 1 2 E rs + RR × 1 + I : E 60 × I : E × R aw + V T × PEEP , now commonly used to calculate the mechanical power (MP) of ventilation. However, it calculates only inspiratory MP. In addition, the inclusion of PEEP in Gattinoni’s equation raises debate because PEEP does not produce net displacement or contribute to MP. Measuring the area within the pressure–volume loop accurately reflects the MP received in a whole ventilation cycle and the MP thus obtained is not influenced by PEEP. The MP of 25 invasively ventilated patients were calculated by Gattinoni’s equation and measured by integration of the areas within the pressure–volume loops of the ventilation cycles. The MP obtained from both methods were compared. The effects of PEEPs on MP were also evaluated. We found that the MP obtained from both methods were correlated by R2 = 0.75 and 0.66 at PEEP 5 and 10 cmH2O, respectively. The biases of the two methods were 3.13 (2.03 to 4.23) J/min (P < 0.0001) and − 1.23 (− 2.22 to − 0.24) J/min (P = 0.02) at PEEP 5 and 10 cmH2O, respectively. These P values suggested that both methods were significantly incongruent. When the tidal volume used was 6 ml/Kg, the MP by Gattinoni’s equation at PEEP 5 and 10 cmH2O were significantly different (4.51 vs 7.21 J/min, P < 0.001), but the MP by PV loop area was not influenced by PEEPs (6.46 vs 6.47 J/min, P = 0.331). Similar results were observed across all tidal volumes. We conclude that the Gattinoni’s equation is not accurate in calculating the MP of a whole ventilatory cycle and is significantly influenced by PEEP, which theoretically does not contribute to MP.
BackgroundHydroxychloroquine (HCQ), one of the disease-modifying antirheumatic drugs, may lead to an inhibition of autophagy. Autophagy, an intracellular self-defense mechanism for the lysosomal degradation of cytoplasmic components such as damaged organelles, plays a role in protecting against neoplasm growth but is also vital for cancer cells due to an increased intracellular metabolic waste.MethodsTaiwan National Health Insurance Database was subjected to analysis to investigate the effect of HCQ exposure on cancer risk in patients with autoimmune diseases. Cancer incidence between patients with or without at least 12-month HCQ use was compared by propensity score-matched landmark analysis. A total of 100,000 participants were enrolled, including 7,662 patients who were diagnosed with autoimmune diseases between January 1, 2000, and December 31, 2012.ResultsAfter propensity score matching, HCQ user and nonuser groups consist of 1,933 patients with a mean follow-up time of 7.82 and 6.7 years, respectively. During the follow-up period, 93 HCQ users and 77 HCQ nonusers developed cancers. Meanwhile, Kaplan–Meier estimates showed no difference in the overall incidence of cancer between HCQ users and nonusers.ConclusionThis propensity score-matched study of Taiwanese patients with autoimmune diseases suggested that HCQ exposure did not increase the cancer risk.
Background: Serum potassium between 3.5 to 5.0 mmol/L is known to be a safe range for patients. The optimal serum potassium level for critically-ill patients with acute kidney injury undergoing continuous renal replacement therapy (CRRT) remains uncertain. This retrospective analysis investigated the association between ICU mortality and potassium concentrations and variability. Methods: ICU patients aged 20 or older, with a minimum of two serum potassium values during received CRRT, treated in ICU in a tertiary hospital in central Taiwan between 1 January 2010 and 30 April 2021 were eligible for inclusion. Patients were categorized into groups of mean potassium: <3.0, 3.0 to <3.5, 3.5 to <4.0, 4.0 to <4.5, 4.5 to <5.0, and ³5.0 mmol/L; potassium variability was divided by quartiles of the average real variation. We analyzed the association between potassium concentration and variability with mortality and performed Cox’s proportional hazard models.Results: We studied 1991 CRRT patients with 9891 serum potassium values within 24 hours after receiving CRRT. There was a J-shaped association between serum potassium and mortality, with the lowest mortality observed in patients with mean potassium concentrations between 3.0 and 4.0 mmol/L. The risk of in-hospital death was also significantly increased in those with the highest variability [HR and 95% CI=1.31(1.03-1.65) for in-hospital mortality; 1.39(1.06-1.82) for 28-day mortality and 1.43(1.11-1.83) for 90-day mortality, respectively].Conclusions: Patients receiving CRRT may benefit from a lower and tighter serum potassium control. During CRRT, progressively increased mortality was noted in patients with higher potassium variability. Thus, careful and timely correction of dyskalemia among these patients is particularly important.
