Late-onset sepsis and mortality among neonates in a Brazilian Intensive Care Unit: a cohort study and survival analysis.

A cohort study was performed from January 2014 to December 2016 in a Brazilian neonatal intensive care unit, including neonates with high risk for infection and death. We estimated bloodstream infection (BSI) incidence and conducted a survival analysis, considering the time to death and to the first episode of BSI as outcomes, comparing very low birth weight (VLBW) neonates with the remaining neonates. An extended Cox model was performed and the hazard ratio (HR) was calculated for different time periods. The study had 1560 neonates included, the incidence and the incidence density of BSI was 22% and 18.6 per 1000 central venous catheter-days, respectively. Considering VLBW neonates as the reference group, the HR for time to death was 4.06 (95% CI 2.75-6.00, P < 0.01) from day 0 to 60 and for time to the first episode of BSI was 1.76 (95% CI 1.31-2.36, P < 0.01) from day 0 to 36. Having the heavier neonates group as reference, the HR for time to the first episode of BSI was 2.94 (95% CI 1.92-4.34, P < 0.01) from day 37 to 90. Late-onset neonatal sepsis prevention measures should consider the differences in risk during time, according to neonates' birth weight.

Late-onset systemic lupus erythematosus: Is it "mild lupus"?

Objective The objective of this paper is to investigate the clinical characteristics and prognosis of patients with late-onset systemic lupus erythematosus (SLE) using a prospective observational cohort. Methods Late-onset SLE (≥50 years old) was compared with adult-onset SLE (≥18 and <50 years old) using 1997 ACR classification criteria for SLE, autoantibodies, disease activity measured by Adjusted Mean SLE Disease Activity Index (AMS), and damage measured by Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI). The standardized mortality ratio (SMR) was calculated. Results A total of 917 patients with SLE were enrolled. The mean number of cumulative ACR criteria in late-onset SLE ( n = 32, 3.5%) was lower than that in adult-onset SLE (4.6 ± 1.2 vs. 5.5 ± 1.4, p < 0.05). The percentage of patients with low complement was lower in late-onset SLE than adult-onset SLE ( p < 0.05). AMS was also lower in late-onset SLE (2.7 ± 2.1 vs. 4.3 ± 2.6, p < 0.01), but SDI was similar between the two groups (50% vs. 43.4%, p = 0.58). The SMR of late-onset SLE was 1.58 (95% CI 0.58-3.43), while the SMR of adult-onset SLE was 3.34 (2.34-4.63). Conclusion Compared with adult-onset SLE, late-onset SLE has a lower number of ACR criteria and lower disease activity. Organ damage is not different, but prognosis and mortality are more favorable.

[Late-onset systemic sclerosis: A retrospective study of 27 patients diagnosed after the age of 70]. / Sclérodermie systémique de révélation tardive : étude rétrospective de 27 patients diagnostiqués après l'âge de 70 ans.

BACKGROUND: The aim of this study was to describe special features of patients with systemic sclerosis (SSc) diagnosed after the age of 70. PATIENTS AND METHODS: This is a retrospective study of patients aged above 70 years at the time of diagnosis of SSc and followed at an internal medicine unit between 2000 and 2015. Co-morbidities and clinical characteristics were analyzed, as well as survival at 1, 2 and 3 years. RESULTS: Of 246 patients, 27 (11%) were included (89% women, 96% Caucasians, age 78.3±4.5 years). Synchronous cancer was noted in 3 patients. SSc was mostly limited cutaneous only (24/27), with telangiectasia (63%), gastroesophageal reflux (59%) and digital ulcers (22%), and was associated with anti-centromere antibody (69%). Interstitial lung disease was not frequent (29%). Pulmonary arterial hypertension (PAH) was suspected at diagnosis of SSc in 14 cases (52%), but only 5 patients had undergone heart catheterization, with severe PAH in 3 cases. Survival at 1 and 3 years was 85.2% and 66.7%, and was worse in the case of suspected PAH, at 78.6% and 57.1% respectively. CONCLUSION: Cases of SSc diagnosed after 70 years are mostly limited cutaneous forms. Suspicion of PAH is frequent, and PAH may be the main initial sign of the disease for patients at this age. There may be association with synchronous cancer. Survival is poor.

Late-onset Neonatal Infections 1997 to 2017 Within a Cohort in Western Sweden-The Last 21 Years of a 43-Year Surveillance.

BACKGROUND: The objective of the study was to assess the epidemiology of late-onset (LO) neonatal invasive infections with surveillance covering 43 years, starting from 1975. METHODS: Observational epidemiologic, retrospective study including a cohort of infants born in western Sweden in 1997-2017, who had a positive blood and cerebral spinal fluid culture between 3 and 120 days of age. A comparison was made of the incidence between 1997-2007 and 2008-2017. Data on LO infections during 3-27 days of life were assessed from 1975. RESULTS: A total of 473 cases of LO infections were registered in 437 patients. The incidence increased from 2.0 to 3.1/1000 live births (LB) between 1997-2007 and 2008-2017 (P < 0.001). The increase in incidence was most pronounced among infants born <28 weeks gestation (from 255 to 398/1000 LB, P < 0.001). The most frequent pathogens were Staphylococcus aureus (25%), coagulase-negative staphylococci (17%), and Escherichia coli (13%). Infections due to group B Streptococci rose from 0.16/1000 LB to 0.33 (P = 0.03). During the whole surveillance period from 1975 to 2017, there were 579 cases between 3 and 27 days of life. Although the incidence increased in 2008-2017 to 1.9/1000 LB after first declining in 1997-2007, the case-fatality rate continued to decline from 27/284 (9.5%) between 1975 and 1996 to 6/182 (3.3%) in 2008 and 2017 (P = 0.01). CONCLUSIONS: The incidence of LO neonatal invasive infections increased during the study period (1997-2017), but the case-fatality rate remained lower than in the previous surveillance period (1975-1996). Further surveillance and interventions with focus on prevention is critical to counteract the increasing incidence among high-risk infants.

Late-onset laryngeal paralysis: Owner perception of quality of life and cause of death.

BACKGROUND: Late-onset laryngeal paralysis (LoLP) is an idiopathic disease of older dogs, and is common in the Labrador Retriever. Owner perspective of how LoLP affects their pet's quality of life (QOL), the degree to which LoLP is perceived to be a life-limiting disease, and how a glottic opening procedure affects these perceptions is not known. OBJECTIVES: (a) To determine owner's perception of late-onset laryngeal paralysis (LoLP) with respect to their dog's QOL; (b) To determine whether LoLP is considered by owners to be a life-limiting disease; (c) To evaluate whether a glottic opening procedure altered QOL and perceived cause of death in affected dogs. METHODS: Owners of Labrador Retrievers with LoLP completed a questionnaire. Questions were asked pertaining to a dog's LoLP, including clinical progression and perception of cause of death, and whether a glottic opening procedure was undertaken. Owners also completed a pet-owner administered QOL survey. RESULTS: Seventy-six owners participated. Overall, 94% of owners felt their dog's LoLP affected QOL, and 47% of owners felt LoLP was a large contributing factor in their dog's death. Dogs that underwent a glottic opening procedure were reported to have a better QOL, and the contribution of LoLP towards their death was less than dogs that did not have surgery. CONCLUSION: Owners of Labrador Retrievers with LoLP perceive LoLP to be a life-limiting disease that negatively impacts their dog's QOL. Arytenoid lateralization surgery had a positive impact on QOL in affected dogs.

Late-onset MADD: a rare cause of cirrhosis and acute liver failure?

Late-onset multiple acyl-CoA dehydrogenase deficiency (MADD) is a severe inborn error of fat metabolism. In late-onset MADD, hepatopathy in the form of steatosis is commonplace and considered a benign and stable condition that does not progress to more advanced stages of liver disease, however, progression to cirrhosis and acute liver failure (ALF) has been reported in two previous case reports. Here, we report a 22-year-old man, who suffered from late-onset MADD and died from cirrhosis and ALF. In the span of three months repeated clinical examinations, blood tests, and diagnostic imaging as well as liver biopsy revealed rapid progression of hepatopathy from steatosis to decompensated cirrhosis with portal hypertension. Routine studies for recognized etiologies found no evident cause besides MADD. This case report supports the findings of the two previous case reports and adds further evidence to the suggestion that late-onset MADD should be considered a rare cause of cirrhosis and ALF.

Long-term outcome and medical radiation exposure in patients hospitalized for cardiovascular disease.

BACKGROUND: Low radiation doses from diagnostic and therapeutic procedures may increase cancer incidence after decades in cardiac patients. The aim of the study was to evaluate the long-term outcome and the prognostic effect of radiological exposure. METHODS: A retrospective cohort study examined 16,311 Italian cardiac patients without cancer consecutively hospitalized between 1970 and 2009 and followed-up for a median of 10 years. Cumulative estimated effective dose was calculated for the imaging procedures. Main causes of death and primary cancer onset were the end points and their relation with radiation exposure was analyzed by Cox model. RESULTS: Over the years, there was an increasing trend of cancer, a decreasing trend of cardiovascular, with stability of other-causes death. Cumulative estimated effective radiation dose was higher in patients who died for cancer (20 ± 19 mSv) compared to cardiovascular (17 ± 17, P < 0.001) and other-causes deaths (15 ± 17, p < 0.001). The cumulative estimated effective dose adjusted HR was 1.004 (95% CI 1.000-1.009, p = 0.045) for cancer death and 1.008 (95% CI 1.005-1.011, p < 0.001) for (fatal and non-fatal) cancer onset. Radiation effective dose was not predictive of cardiovascular mortality (HR = 0.991), nor it was of other types of deaths (HR = 0.995). Smoking was a predictor for cardiovascular mortality, but it was not of other types of deaths. CONCLUSIONS: Non-cardiovascular causes of death are responsible for almost half of later deaths in cardiac patients. The radiological exposure from medical imaging procedures is predictive of cancer risk and cancer death.
