RESUMO
Hypoglycemia due to underlying terminal illness in nondiabetic end-of-life patients receiving palliative care has not been fully studied. For example, we do not have adequate information on the frequency of spontaneous hypoglycemia in patients as occurs during the different stages of palliative care. Depending on the case-mix nature of the palliative care ward, at least 2% of palliative care patients may develop hypoglycemia near the end of life when the remaining life expectancy counts down in days. As many as 25%-60% of these patients will neither have autonomic response nor have neuroglycopenic symptoms during a hypoglycemic episode. Although it is not difficult to diagnose and confirm a true hypoglycemia when it is suspected clinically, an episode of hypoglycemic attack may go unnoticed in some patients in a hospice setting. Current trends in palliative care focus on providing treatments based on a prognosis-based framework, involving shared decision-making between the patient and caregivers, after considering the prognosis, professional recommendations, patient's autonomy, family expectations, and the current methods for treating the patient's physical symptoms and existential suffering. This paper provides professional care teams with both moral and literature support for providing care to nondiabetic patients presenting with hypoglycemia.
RESUMO
INTRODUCTION: Osteoporosis is becoming an impending epidemic in the Asia-Pacific region. The association between risk of osteoporotic fracture (OTPF) and chronic obstructive pulmonary disease (COPD) in East Asian patients is yet to be fully examined. We conducted a nationwide population-based retrospective cohort study of 98,700 patients aged ≥50 years with or without COPD using a national administrative claims dataset. MATERIALS AND METHODS: The patients were divided into COPD and comparison groups comprising 19,740 and 78,960 patients, respectively. The groups were 1 to 4 matched for age, gender, index date, diabetes mellitus, pre-existing osteoporosis and chronic kidney disease. Information such as the geographic area where southern part represented more sunshine exposure, smoking-related diagnoses, alcohol use disorder, whether there was regular use of inhaled corticosteroids and oral corticosteroids, vitamin D prescriptions, Charlson-Deyo comorbidity index score, and other relevant medical comorbidities were extracted for analysis. They were followed up until OTPF or the end of the year 2013. The outcome measure was an osteoporotic vertebral fracture and other long-bone fractures. A multivariate Cox model was constructed to derive adjusted hazard ratios (aHR) for OTPF with corresponding 95% confidence intervals (CI) after controlling for age, sex, insurance premium category, vitamin D prescription, osteoporosis, and coronary heart disease (CHD). Kaplan-Meier curves of the probability of OTPF-free survival for each cohort were compared using the log-rank test. Patients with OTPF during the first follow-up year were excluded from the overall risk calculation. Contributing factors to the increased risk of OTPF in COPD patients were examined in a sensitivity analysis. RESULTS: After a total follow-up of 68,743 patient-years for the COPD group and 278,051 patient-years for the matched comparison group, the HR for OTPF was 1.24 (95% CI [1.02-1.51]; P = 0.0322) in COPD patients. The aHR was increased by 30% for vertebral OTPF (aHR = 1.297, 95% CI [1.020-1.649]; P = 0.0339). Differential lag time sensitivity analysis revealed a progressively elevated risk up to 8-fold increase in women (aHR = 8.0 (95% CI [1.81-35.4]; P < 0.01)) during the fifth follow-up year. COPD patients with pre-existing osteoporosis or given vitamin D prescription harbor a sustained increased risk up to the 5th (aHR, 4.1; 95% CI [1.61-10.35]) and third (aHR, 2.97; 95% CI [1.48-5.97]) follow-up year, respectively. CONCLUSIONS: Our nationwide population-based cohort study demonstrates that East Asian COPD patients aged 50 and beyond do harbor a modestly increased risk for osteoporotic vertebral fractures particularly for those who are female, have pre-existing osteoporosis or require vitamin D prescription.
