Introduction: Antibiotic exposure is associated with a long-lasting alteration in gut microbiota, and may be related to subsequent major chronic diseases such as cardiovascular diseases and cancer. No previous prospective cohort study has investigated associations between duration of antibiotic use during adulthood with mortality from major chronic diseases among populations at usual risk. Hypothesis: We investigated whether a longer duration of antibiotic use was associated with elevated risks of all-cause and cause-specific deaths among women. Methods: This study included 37,510 women aged ≥60 y who were initially free of cardiovascular diseases or cancer from the Nurses’ Health Study. The present analysis included women who reported data on antibiotic use on the 2004 questionnaire when the information was first assessed. We calculated hazard ratios (HR) for all-cause mortality, and deaths from cardiovascular disease (ICD-8 [international classification of diseases, eighth revision, ICD-8], codes 390 to 458) and cancer (ICD-8, 140-209) according to total days of antibiotic use per year (none, less than 15 days, 15 days to less than 2 months, or ≥2 months) in late adulthood (age 60 or older). Follow-up time was calculated from the return date of the 2004 questionnaire until the date of death, or end of follow-up (June 30, 2012), whichever occurred first. Results: During 287,474 person-years of follow-up, we documented 2908 deaths from any cause (including 474 cardiovascular deaths and 906 cancer deaths). Longer duration of antibiotic use was significantly associated with higher risk of death from any cause after adjusted for dietary intake, lifestyle factors, hypertension, hypercholesterolemia, diabetes ( P trend <0.0001), other medication use (such as aspirin, statin, H2 blockers, proton pump inhibitors) ( P trend =0.001), and other characteristics ( P trend =0.038). As compared to women who did not use antibiotics, those who used for ≥2 months in late adulthood had significantly increased risks of all-cause mortality (multivariate-adjusted HR 1.27; 95% CI, 1.07, 1.49) and cardiovascular mortality (HR 1.58; 95% CI, 1.02, 2.46), but not cancer mortality (HR=0.86; 95% CI, 0.63, 1.16). The association between long-term antibiotic use in late adulthood and an elevated risk of all-cause death was more evident among women who also used antibiotics in middle adulthood (during age 40-59) ( P trend =0.002) than among those who did not use during this life stage. Conclusions: Long-term duration of antibiotic exposure especially in late adulthood was associated with increased all-cause and cardiovascular mortality in women.

Objective To evaluate long-term predictors of remission in patients with medication-overuse headache (MOH) by prospective cohort study. Background Knowledge regarding long-term predictors of MOH outcome is limited. Methods Two hundred and forty MOH patients recruited from 2000 to 2005 were included in a one-year follow-up study and then subsequently followed until 31 December 2013. The median follow-up was three years (interquartile range, three years). Predictive values of selected variables were assessed by the Cox proportional hazard regression model. Results At the end of follow-up, 102 (42.5%) patients were in remission. The most important predictors of remission were lower number of headache days per month before the one-year follow-up (HR-hazard ratio = 0.936, 95% confidence interval (CI) 0.884–0.990, p = 0.021) and efficient initial drug withdrawal (HR = 0.136, 95% CI 0.042–0.444, p = 0.001). Refractory MOH was observed in seven (2.9%) and MOH relapse in 131 patients (54.6%). Conclusions Outcome at the one-year follow-up is a reliable predictor of MOH long-term remission.

Abstract Aims As a consequence of modern urban life, an increasing number of individuals are living alone. Living alone may have potential adverse health implications. The long-term relationship between living alone and all-cause and cardiovascular mortality, however, remains unclear. Methods and results Participants from The Copenhagen Male Study were included in 1985–86 and information about conventional behavioural, psychosocial, and environmental risk factors were collected. Socioeconomic position (SEP) was categorized into four groups. Multivariable Cox-regression models were performed with follow-up through the Danish National Registries. A total of 3346 men were included, mean (standard deviation) age 62.9 (5.2) years. During 32.2 years of follow-up, 89.4% of the population died and 38.9% of cardiovascular causes. Living alone (9.6%) was a significant predictor of mortality. Multivariable risk estimates were [hazard ratio (95% confidence interval)] 1.23 (1.09–1.39), P = 0.001 for all-cause mortality and 1.36 (1.13–1.63), P = 0.001 for cardiovascular mortality. Mortality risk was modified by SEP. Thus, there was no association in the highest SEP but for all other SEP categories, e.g. highest SEP for all-cause mortality 1.01 (0.7–1.39), P = 0.91 and 0.94 (0.6–1.56), P = 0.80 for cardiovascular mortality; lowest SEP 1.58 (1.16–2.19), P = 0.004 for all-cause mortality and 1.87 (1.20–2.90), P = 0.005 for cardiovascular mortality. Excluding participants dying within 5 years of inclusion (n = 274) did not change estimates, suggesting a minimal influence of reverse causation. Conclusions Living alone was an independent risk factor for all-cause and cardiovascular mortality with more than three decades of follow-up. Individuals in middle- and lower SEPs were at particular risk. Health policy initiatives should target these high-risk individuals.

The Relationship

<b><i>Objective:</i></b> To further explore the relationship between the blood urea nitrogen to creatinine (BUN/Cr) ratio and the prognosis of patients with acute heart failure (AHF), a two-part study consisting of a prospective cohort study and meta-analysis were conducted. <b><i>Methods:</i></b> A total of 509 hospitalized patients with AHF were enrolled and followed up. Cox proportional hazards regression was used to analyze the relationship between the BUN/Cr ratio and the long-term prognosis of patients with AHF. Meta-analysis was also conducted regarding the topic by searching PubMed and Embase for relevant studies published up to October 2019. <b><i>Results:</i></b> During a median follow-up of 2.8 years, 197 (42.6%) deaths occurred. The cumulative survival rate of patients with a BUN/Cr ratio in the bottom quartile was significantly lower than in the other 3 groups (log-rank test: <i>p</i> = 0.003). In multivariate Cox regression models, the mortality rate of AHF patients with a BUN/Cr ratio in the bottom quartile was significantly higher than in the top quartile (adjusted HR 1.52; 95% CI 1.03–2.24). For the meta-analysis, we included 8 studies with 4,700 patients, consisting of 7 studies from the database and our cohort study. The pooled analysis showed that the highest BUN/Cr ratio category was associated with an 77% higher all-cause mortality than the lowest category (pooled HR 1.77; 95% CI 1.52–2.07). <b><i>Conclusions:</i></b> Elevated BUN/Cr ratio is associated with poor prognosis in patients with AFH and is an independent predictor of all-cause mortality.

AbstractThe aim of this study was to explore the association between serum Mg and cardiovascular mortality in the peritoneal dialysis (PD) population. This prospective cohort study included prevalent PD patients from a single centre. The primary outcome of this study was cardiovascular mortality. Serum Mg was assessed at baseline. A total of 402 patients (57 % male; mean age 49·3±14·9 years) were included. After a median of 49·9 months (interquartile range: 25·9–68·3) of follow-up, sixty-two patients (25·4 %) died of CVD. After adjustment for conventional confounders in multivariate Cox regression models, being in the lower quartile for serum Mg level was independently associated with a higher risk of cardiovascular mortality, with hazards ratios of 2·28 (95 % CI 1·04, 5·01), 1·41 (95 % CI 0·63, 3·16) and 1·62 (95 % CI 0·75, 3·51) for the lowest, second and third quartiles, respectively. A similar trend was observed when all-cause mortality was used as the study endpoint. Further analysis showed that the relationships between lower serum Mg and higher risk of cardiovascular and all-cause mortality were present only in the female subgroup, and not among male patients. The test for interaction indicated that the associations between lower serum Mg and cardiovascular and all-cause mortality differed by sex (P=0·008 andP=0·011, respectively). In conclusion, lower serum Mg was associated with a higher risk of cardiovascular and all-cause mortality in the PD population, especially among female patients.

Introduction: Hospitalization represents a major factor that may precipitate the loss of functional status and the cascade into dependence. The main objective of our study was to determine the effect of functional status measured before hospital admission on survival at one year after hospitalization in elderly patients. Methods: Prospective cohort study of adult patients (over 65 years of age) admitted to either the general ward or intensive Care units (ICU) of a tertiary teaching hospital in Buenos Aires, Argentina. Main exposure was the pre-admission functional status determined by means of the modified “VIDA” questionnaire, which evaluates the instrumental activities of daily living. We used a multivariate Cox proportional hazards model to estimate the effect of prior functional status on time to all-cause death while controlling for measured confounding. Secondarily, we analyzed the effect of post-discharge functional decline on long-term outcomes. Results: 297 patients were included in the present study. 12.8% died during hospitalization and 86 patients (33.2%) died within one year after hospital discharge. Functional status prior to hospital admission, measured by the VIDA questionnaire (e.g., one point increase), was associated with a lower hazard of all-cause mortality during follow-up (Hazard Ratio [HR]: 0.96; 95% Confidence Interval [CI]: 0.94–0.98). Finally, functional decline measured at 15 days after hospital discharge, was associated with higher risk of all-cause death during follow-up (HR: 2.19, 95% CI: 1.09–4.37) Conclusion: Pre-morbid functional status impacts long term outcomes after unplanned hospitalizations in elderly adults. Future studies should confirm these findings and evaluate the potential impact on clinical decision-making.
