Epidemiological Characteristics

<b><i>Introduction:</i></b> Old age is an independent risk factor (RF) for severe COVID-19; evidence for clinico-epidemiological characteristics among elderly COVID-19 patients is scarce. We aimed to analyze clinical and epidemiological characteristics and comorbidities associated with COVID-19 inpatients in age-stratified populations of an elderly COVID-19 cohort. <b><i>Methods:</i></b> We conducted a retrospective cohort study, using nationwide registry data of COVID-19 patients hospitalized before October 31, 2020 (major information entered in the registry as of December 28, 2020). Participants were divided by age according to the Japan Geriatrics Society and the Japan Gerontological Society: pre-old (65–74 years), old (75–89 years), and super-old (≥90 years). Multivariable logistic regression (MLR) analyses were conducted to identify stratified risk and relationships with comorbidities associated with worse outcomes in different age-groups of elderly patients. Demographics and supportive care were evaluated by category. <b><i>Results:</i></b> Data of 4,701 patients from 444 hospitals were included. Most patients (79.3%) had at least one comorbidity; the proportion of patients with hypertension was high in all categories. The proportion of patients with dementia, cardiovascular disease, and cerebrovascular disease increased with age. The percentage of patients who underwent invasive mechanical ventilation/extracorporeal membrane oxygenation was lower in the super-old group. In total, 11.5% of patients died (5.3%, pre-old; 15.2%, old; and 22.4%, super-old). MLR showed that the risk of critical illness differed among age-groups. Male sex was a significant RF in all ages. Collagen disease, moderate to severe renal disorder, and dialysis were significant RFs in older patients, while hematological malignancies and metastatic tumors were more important RFs for severe disease in relatively younger patients. Most of the RFs for critical illnesses were associated with death. <b><i>Conclusion:</i></b> Differences in the epidemiological and clinical characteristics among the different age-groups were found.

Abstract Objective: To describe the incidence, risk factors, and outcomes of bloodstream infections (BSIs) in patients with coronavirus disease 19 (COVID-19).Methods: This was a single-center retrospective cohort study of adults admitted for COVID-19 with BSIs. Data were collected by electronic medical record review. BSIs were defined as positive blood cultures (BCs) with a known pathogen in one or more BCs or the same commensal organism in two or more BCs. Results: Of 565 eligible patients, 290 (51.3%) had BCs done, with 39 (13.4%) having a positive result. In univariable analysis, male sex, black/African American race, admission from a facility, hemiplegia, altered mental status, and a higher Charlson Comorbidity Index were positively associated with a positive BC, whereas obesity and low systolic blood pressure (SBP) were negatively associated. Patients with positive BCs were more likely to have severe disease, be admitted to the Intensive Care Unit (ICU), require mechanical ventilation, have septic shock, and higher mortality. In multivariable logistic regression, factors that were independent predictors of a positive BC were male sex (OR=2.75, p=0.03), hypoalbuminemia (OR=3.3, p=0.01), ICU admission (OR=5.3, p<0.0001), SBP < 100 (OR=3.7, p=0.03) and having a procedure (OR=10.5, p<0.0001). Patients with an abnormal chest x-ray on admission were less likely to have a positive BC (OR=0.25, p=0.007). Conclusions: We found that independent predictors of BSIs in COVID-19 patients included male sex, abnormal chest x-ray, hypoalbuminemia, admission to ICU, low SBP, and having a procedure during hospital stay.

Abstract Severe covid-19 pneumonia has posed critical challenges for the research and medical communities. Older age, male sex, and comorbidities increase the risk for severe disease. For people hospitalized with covid-19, 15-30% will go on to develop covid-19 associated acute respiratory distress syndrome (CARDS). Autopsy studies of patients who died of severe SARS CoV-2 infection reveal presence of diffuse alveolar damage consistent with ARDS but with a higher thrombus burden in pulmonary capillaries. When used appropriately, high flow nasal cannula (HFNC) may allow CARDS patients to avoid intubation, and does not increase risk for disease transmission. During invasive mechanical ventilation, low tidal volume ventilation and positive end expiratory pressure (PEEP) titration to optimize oxygenation are recommended. Dexamethasone treatment improves mortality for the treatment of severe and critical covid-19, while remdesivir may have modest benefit in time to recovery in patients with severe disease but shows no statistically significant benefit in mortality or other clinical outcomes. Covid-19 survivors, especially patients with ARDS, are at high risk for long term physical and mental impairments, and an interdisciplinary approach is essential for critical illness recovery.

Objective of the research: to present the clinical and laboratory peculiarities of modern whooping cough in hospitalized children of different ages. Materials and methods: сlinical and laboratory characteristics of whooping cough were analyzed in 88 hospitalized sick children aged 1 month to 18 years in groups of children: group 1 – children under 1 year old; group 2 – children 1–6 years old; group 3 – children 7–17 years old. DNA of causative agents of pertussis infection was isolated by PCR in nasopharyngeal swabs using a commercial kit AmpliSens®Bordetella multi-FL (Moscow). Results: children of group 1 in 90% (n=43) of cases were not vaccinated against whooping cough, severe forms were recorded in 17% (n=8) of children of the 1st year of life, and in 15% (n=7) – due to respiratory rhythm disturbances. The diagnosis was confirmed by PCR in 94% (n=45) of children, leukocytosis with lymphocytosis was detected in 81,5% (n=101). Along with hematological changes typical for whooping cough, 79% (n=38) of patients in the first year of life had thrombocytosis (>400×109/l), which was most pronounced in severe disease course 511,5 [425; 568,5]×109/l vs 421 [347; 505,5]×109/l; p<0,05, which has no tendency to decrease throughout the entire observation period and correlates with the level of leukocytes (rs=0,69; p<0,001). Patients over 7 years old in 88% (n=21) of cases were vaccinated against whooping cough, but 79% (n=27) hemograms had no characteristic changes, which, along with a low frequency of confirmation of the diagnosis by PCR 22% (n=4), made it difficult to diagnose whooping cough. Conclusion: children over 7 years of age may not have characteristic hematological changes and PCR diagnostics are insufficiently effective, which contributes to the spread of whooping cough in family foci.

Epidemiological Characteristics

BACKGROUND Coronavirus disease (Covid-19) is a zoonotic disease of novel origin that posed a continuous threat to health worldwide after taking the shape of the pandemic. An understanding of disease epidemiology is supportive in timely preventive and control measures as well as contact tracing and curbing surveillance activities. OBJECTIVE The objective of our study was to determine the epidemiological characteristics of COVID-19 confirmed cases reported at the National Institute of Health Pakistan and elements of its spread in Pakistan. METHODS A retrospective record review was conducted at the National Institute of Health (NIH) Islamabad, Pakistan from January 25 to April 4, 2020. Univariate and bivariate analysis was done with 95% CI and p<0.05. RESULTS A total of 14,422 samples of suspected COVID-19 cases were received with a positivity rate of 9% (n=1348). Among all 70% (n=939) were male. The median age was 41years of age (range: 01-99Years). Among all, 19% were from 30-39 years old followed by 50-59 years old (17%). Children remained the least affected by 3% (n=35). Of the total reported cases, 55% (n=735) have reported the travel history within the last 14 days. Among these travelers’ international travelers were 23% (n=166) and domestic travelers were 77% (n=569). Travel history including both international and domestic remained significantly associated with the different age groups and Young adults remained more vulnerable to COVID-19 (P=0.03). Fever, SOB, and Cough remained the most significantly associated (P<0.05) in all age groups. CONCLUSIONS A higher incidence of COVID-19 among elderly men suggests robust quarantine measures for this target population. An escalating incidence of local transmission needs strict social distancing and hygiene practices to help flatten the curve. An extensive multi-center study is also recommended for a full understanding of disease dynamics.

The increasing popularity of electronic cigarettes in past decades has aroused public health concern. This study aims to review the literature on the prevalence of e-cigarette use among the general adult and young populations in Europe. We searched Medline and Google Scholar from September 2019, and included “prevalence of e-cigarettes”, “electronic cigarettes” or “e-cigarettes”, and “electronic nicotine delivery system” or “vaping”. The prevalence of current e-cigarette use ranged from 0.2% to 27%, ever-use ranged from 5.5% to 56.6% and daily use ranged from 1% to 2.9%. Current smokers of conventional cigarettes showed the highest prevalence for the use of e-cigarettes, ranging from 20.4% to 83.1%, followed by ex-smokers, with ranges from 7% to 15%. The following socio-demographic factors were associated with a higher chance of using e-cigarettes: male sex and younger age groups; results for economic status were inconclusive. In European countries, there is a higher prevalence of e-cigarette use among males, adolescents and young adults, smokers of conventional cigarettes, and former smokers.

Introduction. Lung cancer represents the most common malignant tumour among men, and appears more and more frequently among women in many countries worldwide. The aims of this descriptive epidemiological study were to evaluate the mortality trends of all malignant tumours and lung cancer in Central Serbia from 1990 to 1999, and to estimate the incidence, mortality and the basic demographic characteristics of lung cancer in Central Serbia in 1999. Material and methods. The source of data concerning cancer cases in 1999 was the Cancer Registry of Central Serbia, while data of the Republic Statistics Institute were used for the analysis of mortality trends for the period 1990-1999. All rates were standardized by the direct method, to the world standard population. Confidence intervals for mortality rates were assessed with 95% level of probability. Linear regression coefficient was determined by Fisher's test. Results. The mortality rates showed rising tendencies for both lung cancer (y=-1876.26+0.96x, p=0.028 for men; y=654.78U).33x, p-0.001 for women) and all malignant tumours (y=-4139.88+2.15x, p=0.163 for men; y=3649.68 + 1.88x, p=0.016 for women), with statistically significant increase being observed for all trends, except all malignant tumours among men. In the year 1999, lung cancer ranked first among men and third among women, with 29.2% and 10.3% of cancer mortality respectively. The age-specific mortality rates were much higher in men in all age groups. Mortality increased with age and the highest rates were found in the age group 70-74 for both sexes. The highest incidence and mortality rates were reported in Belgrade, Moravicki and Sumadijski district. .

<b><i>Background:</i></b> New integrative hidradenitis suppurativa (HS) lesion pattern phenotypes have been proposed, an inflammatory phenotype (IP) and a follicular phenotype (FP). They are characterized by different lesion patterns, symptoms, and risks of disease progression. <b><i>Objectives:</i></b> To evaluate whether lesion pattern phenotypes (1) have a different cardiovascular risk factor profile, and (2) are associated with a different therapeutic approach in the setting of an HS clinic. <b><i>Methods:</i></b> A retrospective cohort study was conducted on 233 patients with HS. They were classified according to lesion pattern phenotype criteria. Data regarding cardiovascular risk factors and treatment decisions were gathered. <b><i>Results:</i></b> One hundred and seventeen HS patients (50.21%) were classified as FP and 112 (48.07%) as IP. IP was associated with more severe disease and greater impairment of quality of life. Regardless of disease severity, patients with IP may have a higher cardiovascular risk, assessed according to higher C-reactive protein (CRP) levels (12.75 vs. 5.89, <i>p</i> = 0.059). The lesion pattern phenotype also influenced treatment decisions regardless of disease severity. Patients with IP were more likely to be treated with systemic corticosteroids and adalimumab, showing that lesion pattern phenotypes are associated with different therapeutic approaches. <b><i>Conclusions:</i></b> IP is associated with higher CRP values, suggesting a greater cardiovascular risk in these patients and also a different therapeutic approach. This information could help guide dermatologists in the management of HS patients and help to determine future treatment recommendations.

Water Fluoridation

Abstract Background Tooth decay can cause pain, sleepless nights and loss of productive workdays. Fluoridation of drinking water was identified in the 1940s as a cost-effective method of prevention. In the mid-1970s, fluoride toothpastes became widely available. Since then, in high-income countries the prevalence of tooth decay in children has reduced whilst natural tooth retention in older age groups has increased. Most water fluoridation research was carried out before these dramatic changes in fluoride availability and oral health. Furthermore, there is a paucity of evidence in adults. The aim of this study is to assess the clinical and cost-effectiveness of water fluoridation in preventing invasive dental treatment in adults and adolescents aged over 12. Methods/design Retrospective cohort study using 10 years of routinely available dental treatment data. Individuals exposed to water fluoridation will be identified by sampled water fluoride concentration linked to place of residence. Outcomes will be based on the number of invasive dental treatments received per participant (fillings, extractions, root canal treatments). A generalised linear model with clustering by local authority area will be used for analysis. The model will include area level propensity scores and individual-level covariates. The economic evaluation will focus on (1) cost-effectiveness as assessed by the water fluoridation mean cost per invasive treatment avoided and (2) a return on investment from the public sector perspective, capturing the change in cost of dental service utilisation resulting from investment in water fluoridation. Discussions There is a well-recognised need for contemporary evidence regarding the effectiveness and cost-effectiveness of water fluoridation, particularly for adults. The absence of such evidence for all age groups may lead to an underestimation of the potential benefits of a population-wide, rather than targeted, fluoride delivery programme. This study will utilise a pragmatic design to address the information needs of policy makers in a timely manner.

AimThis study’s objective was to assess the risk of severe in-hospital complications of patients admitted for COVID-19 and diabetes mellitus (DM).DesignThis was a cross-sectional study.SettingsWe used pseudonymised medical record data provided by six general hospitals from the HM Hospitales group in Spain.Outcome measuresMultiple logistic regression analyses were used to identify variables associated with mortality and the composite of mortality or invasive mechanical ventilation (IMV) in the overall population, and stratified for the presence or absence of DM. Spline analysis was conducted on the entire population to investigate the relationship between glucose levels at admission and outcomes.ResultsOverall, 1621 individuals without DM and 448 with DM were identified in the database. Patients with DM were on average 5.1 years older than those without. The overall in-hospital mortality was 18.6% (N=301), and was higher among patients with DM than those without (26.3% vs 11.3%; p<0.001). DM was independently associated with death, and death or IMV (OR=2.33, 95% CI: 1.7 to 3.1 and OR=2.11, 95% CI: 1.6 to 2.8, respectively; p<0.001). In subjects with DM, the only variables independently associated with both outcomes were age >65 years, male sex and pre-existing chronic kidney disease. We observed a non-linear relationship between blood glucose levels at admission and risk of in-hospital mortality and death or IMV. The highest probability for each outcome (around 50%) was at random glucose of around 550 mg/dL (30.6 mmol/L), and the risks flattened above this value.ConclusionThe results confirm the high burden associated with DM in patients hospitalised with COVID-19 infection, particularly among men, the elderly and those with impaired kidney function. Moreover, hyperglycaemia on admission was strongly associated with poor outcomes, suggesting that personalised optimisation could help to improve outcome during the hospital stay.
