SummaryTo investigate the joint association of patient and strain characteristics with the outcome of meningococcal disease (MD), data were collected on 563 consecutive cases of MD reported between 1989 and 1990 in The Netherlands. The meningococcal isolates were characterized with regard to their surface characteristics. Sequelae occurred in 8.5% of the patients, and were only associated with the presence of bacteraemia. The case-fatality rate was 7.7%. Infants aged ≤ 5 months and patients in the age-groups of 10–19 years and ≥ 50 years had an increased risk for a fatal outcome compared with children from 6 months to 9 years old (Odds Ratios [ORs]: 5.1, 3.4 and 9.8, respectively). The OR for females versus males was 2.3. The ORs for patients with bacteraemia, or a combination of bacteraemia and meningitis, compared with meningitic patients, were 2.3 and 3.1. Meningococcal strain characteristics did not influence the case-fatality rate substantially. In conclusion, host factors were found to be determinants for a fatal outcome of MD in The Netherlands from 1989 to 1990.

SUMMARYTo identify determinants for mortality and sequelae and to analyse the spatial distribution of meningococcal disease, we linked four national Danish registries. In the period 1974–2007, 5924 cases of meningococcal disease were registered. Our analysis confirms known risk factors for a fatal meningococcal disease outcome, i.e. septicaemia and high age (>50 years). The overall case-fatality rate was 7·6%; two phenotypes were found to be associated with increased risk of death; C:2a:P1.2,5 and B:15:P1.7,16. B:15:P1.7,16 was also associated with excess risk of perceptive hearing loss. The incidence rates of meningococcal disease were comparable between densely and less densely populated areas, but patients living further from a hospital were at significantly higher risk of dying from the infection. To improve control of meningococcal disease, it is important to understand the epidemiology and pathogenicity of virulent ‘successful clones’, such as C:2a:P1.2,5 and B:15:P1.7,16, and, eventually, to develop vaccines against serogroup B.

The annual incidence rate of serogroup W invasive meningococcal disease in the Netherlands increased from < 0.05/100,000 (n < 10) before 2015 to 0.5/100,000 (n = 80) in 2017. Most isolates (94%) belong to clonal complex 11. The incidence rate is highest among  < 5 year-olds and 15–24 year-olds. The case fatality rate was 12% (17/138) in 2015–2017. From May 2018, MenACWY vaccination replaces MenC vaccination at age 14 months and from October 2018, 13–14 year-olds are offered MenACWY vaccination.

Abstract Background Various patient demographic and clinical characteristics have been associated with poor outcomes for individuals with coronavirus disease 2019 (COVID-19). To describe the importance of age and chronic conditions in predicting COVID-19 related outcomes. Methods Search strategies were conducted in PubMed/MEDLINE. Daily alerts were created. Results A total of 28 studies met our inclusion criteria. Studies varied broadly in sample size (n=21 to more than 17,000,000). Participants mean age ranged from 48 years to 80 years and the proportion of male participants ranged from 44%-82%. The most prevalent underlying conditions in patients with COVID-19 were hypertension (range: 15% - 69%), diabetes (8% - 40%), cardiovascular disease (4% - 61%), chronic pulmonary disease (1% - 33%), and chronic kidney disease (range 1% - 48%). These conditions were each associated with an increased in-hospital case fatality rate ranging from 1% to 56%. Overall, older adults have a substantially higher case fatality rate (CFR) as compared with younger individuals affected by COVID-19 (42% for those &lt;65 vs 65% &gt; 65 years ). Only one study examined the association of chronic conditions and the risk of dying across different age groups; their findings suggested similar trends of increased risk in those &lt; 65 and those &gt; 65 years as compared to those without these conditions. Conclusions There has been a traditional, single condition approach to consideration of how chronic conditions and advancing age relate to COVID-19 outcomes. A more complete picture of the impact of burden of multimorbidity and advancing patient age is needed.

The main objective was to compare the in-hospital case-fatality rate of leptospirosis between pediatric (< 19 years) and adult (>19 years) patients, taking into account gender, renal function, duration of symptoms and jaundice. Medical records of 1016 patients were reviewed. Comparative analysis was restricted to 840 patients (100 pediatric, 740 adults) with recorded information on the variables included in the analysis. Among these patients 81.7% were male and 91.5% were icteric. The case-fatality rate of leptospirosis was 14.4%. The odds of death adjusted for gender, jaundice, duration of symptoms, serum urea and serum creatinine were almost four times higher for the adult than for the pediatric group (odds ratio (OR) = 3.94; 95% confidence interval = 1.19-13.03, p = 0.029). Among adults, increased age was also significantly and independently associated with increased risk of death (p < 0.01). Older patients were also more often treated by dialysis. In conclusion, the data suggest that the in-hospital case fatality rate of leptospirosis is higher for adults than for children and adolescents, even after taking into account the effects of several potential risk factors of death. Among adults, older age was also strongly and independently associated with higher risk of death.

AbstractIncidence of hip fractures has remained unchanged during the pandemic with overlapping vulnerabilities observed in patients with hip fractures and those infected with COVID-19. We aimed to investigate the independent impact of COVID-19 infection on the mortality of these patients. Healthcare databases were systematically searched over 2-weeks from 1st–14th November 2020 to identify eligible studies assessing the impact of COVID-19 on hip fracture patients. Meta-analysis of proportion was performed to obtain pooled values of prevalence, incidence and case fatality rate of hip fracture patients with COVID-19 infection. 30-day mortality, excess mortality and all-cause mortality were analysed using a mixed-effects model. 22 studies reporting 4015 patients were identified out of which 2651 (66%) were assessed during the pandemic. An excess mortality of 10% was seen for hip fractures treated during the pandemic (OR 2.00, p = 0.007), in comparison to the pre-pandemic controls (5%). Estimated mortality of COVID-19 positive hip fracture patients was four-fold (RR 4.59, p < 0.0001) and 30-day mortality was 38.0% (HR 4.73, p < 0.0001). The case fatality rate for COVID-19 positive patients was 34.74%. Between-study heterogeneity for the pooled analysis was minimal (I2 = 0.00) whereas, random effects metaregression identified subgroup heterogeneity for male gender (p < 0.001), diabetes (p = 0.002), dementia (p = 0.001) and extracapsular fractures (p = 0.01) increased risk of mortality in COVID-19 positive patients.

SUMMARYIn a retrospective epidemiological study, 293 meningococcal disease patients hospitalized during 1985–2002, were examined for fatality and risk factors related to death. The overall case fatality rate (CFR) was 8·2%, but increased from 4% during 1985–1993 to 17% during 1994–2002. The latter 9-year period was characterized by more serogroup C infections and more patients with thrombocytopenia on admission to hospital. All patients categorized as meningitis on admission survived. Of the 24 patients who died, 21 had meningococcal skin rash on admission, 23 had an onset to admission time of ⩽24 h, and 16 had severe septicaemia with hypotension and/or ecchymoses without meningitis on admission. By multivariate analyses, a short onset to admission time, >50 petechiae, thrombocytopenia and severe septicaemia on admission were associated with fatality. More lives could be saved through earlier admission to hospital. This can be achieved through more information to the public about the early signs of meningococcal septicaemia, with the recommendation to look for skin rash in patients with acute fever during the first day and night.

Background: Rajshahi medical college hospital is a tertiary care teaching and referral center in the North-West part of Bangladesh. To assess the epidemiological trend in hospital admission, including morbidity and mortality pattern of illness in the pediatric population, it needs to develop effective health care planning, appropriate resource allocation, and integration of existing health care service facilities. Objective: To evaluate the diseases and deaths of children admitted in the department of pediatrics, Rajshahi medical college hospital, Rajshahi. Materials and methods: This is a retrospective study. The collected case records of all patients admitted in the department of pediatrics from 1st January 2017 to 31st December 2019 (3 years) were analyzed.  Result: A total of 62000 children were admitted during the mentioned study period. All the patients were distributed into three age groups infant, under five, and more than five, contributing 22%, 27.5%, and 19%, respectively. Acute watery diarrhea (21%), hereditary hemolytic anemia (18%), bronchopneumonia (10.4%), acute gastritis (9.4%), and acute bronchiolitis and wheezy child (7.17%) were the top five diseases in each of the three years of admission. Among the total admitted patients, 1003 (1.61%) patients died. Infant, under five, and more than five age groups constitute 61.3%, 28.1%, and 15.1%, respectively. Encephalitis and fulminant hepatic failure found the top two diseases causing death with a case fatality rate was 61% and 43%, respectively. The next highest case fatality rate was found in acute leukemia (15%). Other common causes of death include meningitis, cerebral palsy with complications (7.5%), bronchopneumonia with complications (3.8%). Conclusion: An admission-related comprehensive evaluation of this study will help to understand the diseases and death patterns of a hospital, leading to the development of more effective planning and case management strategies.

The study was conducted on 106 E. coli isolates to determine the phylogenetic group, serotype and carriage of Class 1 integrons in isolates and ascertain their association along with other parameters with vital disease measures in broiler flocks affected with colibacillosis. Out of 32 isolates of which “O” antigen was characterized, serogroup O2 comprising of 12 (37.5%) isolates was most prevalent in the present study. Most of the isolates (85/106; 80.19%) belonged to phylogenetic group B2. Mean apparent morbidity, mortality and case fatality rate (CFR) were 3.77%, 2.32% and 61.49%, respectively. There was significant difference in number of outbreaks reported in different age groups (p less than 0.0001). Also, there was significant association between phylogenetic group and age of outbreak due to E. coli (p=0.024). Comparatively, no significant association was observed between age of outbreaks and serotypes (p=0.980). There was significant association between various disease measures and E. coli isolates affiliated to various phylogenetic groups and serotypes. All the measures (apparent morbidity, mortality and CFR) of disease were highest in outbreaks due to isolates of phylogenetic group B2 and serogroup O20. However, the measures were not significantly affected by the presence of integrons in the E. coli.

Abstract Background Previous studies have indicated coronavirus disease 2019 (COVID-19) patients with cancer have a high fatality rate. Methods We conducted a systematic review of studies that reported fatalities in COVID-19 patients with cancer. A comprehensive meta-analysis that assessed the overall case fatality rate and associated risk factors was performed. Using individual patient data, univariate and multivariable logistic regression analyses were used to estimate odds ratios (OR) for each variable with outcomes. Results We included 15 studies with 3019 patients, of which 1628 were men; 41.0% were from the United Kingdom and Europe, followed by the United States and Canada (35.7%), and Asia (China, 23.3%). The overall case fatality rate of COVID-19 patients with cancer measured 22.4% (95% confidence interval [CI] = 17.3% to 28.0%). Univariate analysis revealed age (OR = 3.57, 95% CI = 1.80 to 7.06), male sex (OR = 2.10, 95% CI = 1.07 to 4.13), and comorbidity (OR = 2.00, 95% CI = 1.04 to 3.85) were associated with increased risk of severe events (defined as the individuals being admitted to the intensive care unit, or requiring invasive ventilation, or death). In multivariable analysis, only age greater than 65 years (OR = 3.16, 95% CI = 1.45 to 6.88) and being male (OR = 2.29, 95% CI = 1.07 to 4.87) were associated with increased risk of severe events. Conclusions Our analysis demonstrated that COVID-19 patients with cancer have a higher fatality rate compared with that of COVID-19 patients without cancer. Age and sex appear to be risk factors associated with a poorer prognosis.
