Background Pneumococcal conjugate vaccines (PCVs) are recommended for use in pediatric immunization programs worldwide. Few data are available on their effect against mortality. We present a multi-country evaluation of the population-level impact of PCVs against death due to pneumonia in children less then 5 years. Methods We obtained national-level mortality data between 2000-2016 from ten Latin American and Caribbean countries, using the standardized protocol. Time series models were used to evaluate the decline in all-cause pneumonia deaths during the post-vaccination period while controlling for unrelated temporal trends using control causes of death. Results The estimated declines in pneumonia mortality following the introduction of PCVs ranged from 11% to 35% among children aged 2-59 months in five countries Colombia (24%, 95% credible interval 3-35%), Ecuador (25%, 4-41%), Mexico (11%, 3-18%), Nicaragua (19%, 0-34%), and Peru (35%, 20-47%). In Argentina, Brazil, and the Dominican Republic, the declines were not detected in the aggregated age group but were detected in certain age strata. In Guyana and Honduras, the estimates had large uncertainty, and no declines were detected. Across the ten countries, most of which have low to moderate incidence of pneumonia mortality, PCVs have prevented nearly 4500 all-cause pneumonia deaths in children 2-59 months since introduction. Conclusions Although the data quality was variable between countries, and the patterns varied across countries and age groups, the balance of evidence suggests that mortality due to all-cause pneumonia in children declined after PCV introduction. The impact could be greater in populations with a higher pre-vaccine burden of pneumonia.An ultrasound-assisted ionic liquid (IL) salting-out microextraction system was developed and applied for the extraction of quinolone antibiotics from urine. A precipitate was formed from the salt and IL, and it acted as the sorbent for the analytes. The precipitate containing the analyte was separated by filtration, redissolved, and the solution then was evaporated. The resulting extract was redissolved for high-performance liquid chromatographic analysis. Several parameters, including type and volume of IL, the type and amount of salts, sample pH, temperature and extraction time were optimized. Under the optimal experimental conditions, the limits of detection for fleroxacin and ciprofloxacin were 3.12 and 4.97 μg L-1, respectively. When the present method was applied to real urine sample analysis, the analyte recoveries ranged from 82.3 to 106.8%. This ultrasound-assisted IL salting-out microextraction system had the characteristics of high recoveries, shorter separation time and easy-to-perform collection procedure, which yielded the method to have potential for wide application.Background Household contacts of patients with drug-resistant tuberculosis are at high risk for being infected with Mycobacterium tuberculosis and for developing tuberculosis disease. To guide regimen composition for the empirical treatment of tuberculosis infection and disease in these household contacts, we estimated drug resistance profile concordance between index patients with drug-resistant tuberculosis and their household contacts. Methods We performed a systematic review and meta-analysis of studies published through July 24, 2018 and reported resistance profiles of drug-resistant tuberculosis index and secondary cases within their households. learn more Using a random-effects meta-analysis, we estimated resistance profile concordance, defined as the percentage of secondary cases whose M. tuberculosis strains were resistant to the same drugs as strains from their index cases. We also estimated isoniazid/rifampin concordance, defined as whether index and secondary cases had identical susceptibilities for isoniazid and rifampin only. Results We identified 33 eligible studies, which evaluated resistance profile concordance between 484 secondary cases and their household index cases. Pooled resistance profile concordance was 54.3% (95% confidence interval [CI] 40.7-67.6, I2=85%). Pooled isoniazid/rifampin concordance was 82.6% (95% CI 72.3-90.9; I2=73%). Concordance estimates were similar in a sub-analysis of 16 studies from high tuberculosis-burden countries. There were insufficient data to perform a sub-analysis among pediatric secondary cases. Conclusion Household contacts of drug-resistant TB patients should receive treatment for TB infection and disease that assumes that they, too, are infected with a drug-resistant M. tuberculosis strain. Whenever possible, drug susceptibility testing should be performed for secondary cases to optimize regimen composition.Aralia continentalis (AC) is a perennial herb that has long been used as a traditional medicine for many diseases. Continentalic acid (CA) and kaurenoic acid (KA) are major diterpenoids in AC, which are known to exert various pharmacological activities. This study focuses on the optimization of the extraction of CA and KA from dried AC roots by evaluating the influence of different extraction conditions on their yield. Five extraction variables were examined sample weight, solvent concentration, extraction time, solid matrix and the number of repeated extractions. The analytical method used in this study was also validated in terms of linearity, limit of detection, limit of quantification, precision and accuracy. The CA and KA yields were measured by high-performance liquid chromatography analysis. The results show that CA and KA were the highest when unpulverized samples (3.75 g) were subjected to a single extraction for 5 h using 50% ethanol (300 mL) as the solvent. These conditions are proposed for the optimization of the extraction of CA and KA from AC.Introduction Clinical practice guidelines need rigorous and transparent methods for summarizing the evidence, rate its certainty and moving from evidence to recommendations. We describe an intervention to support local efforts to provide optimal and safer care bridging the gap between researchers and local busy clinicians. Methods A group of methodologists provided a wide range of research services to the medical community of a local non-teaching general hospital in Italy. Methodological support encompassed synthesis of evidence, rating of uncertainty and moving from evidence to recommendations. Local professionals were asked to judge GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology and its impact on patients' safety, professional liability, and guideline reliability. The research team then reflected on the barriers of implementing GRADE in local settings. Results Seven clinical recommendations about frequent complex medical conditions were produced. Few local clinicians completed the project. All clinicians found the GRADE methodology a guarantee for defending excellent standards of care. However, we identified a diffuse sense of inability to improve clinical behaviours as negative effects of general poor working conditions, in particular the strained health care workforce. Discussion Current financial constraints may be impeding the ability of clinicians in improving their clinical practice through adaptation and use of evidence. A successful integration of evidence-based guidelines cannot be separated from an activate promotion by the institutional management.Arthroplasty registries represent a fundamental tool for the production of evidence in total joint replacement. Italy started in 2005 a national registry (Italian Arthroplasty Registry - RIAP) organised as federation of regional registries under the coordination of the Istituto Superiore di Sanità. However, data collection still appears to be hardened by the additional workload required from clinicians. The aim of the study was to evaluate the data entry times for an inexperienced operator and the relative learning curve. The analysis carried out shows that after 15 cases, a plateau of about two minutes is reached for the compilation of a single case of primary hip and knee arthroplasty, up to 4 minutes for the shoulder and for revision surgery. The work burden for the orthopedist does not seem to justify the reluctance in data collection observed in these years of RIAP experience.According to current vital statistics suicide appears as a growing public health problem in most Western countries. However, suicide is rarely discussed in scientific journals, possibly because of a persisting moral stigma. As a consequence, the diverse bases of suicidal behavior are little understood while the role of Chronic-Degenerative Terminal Diseases (CDTD) has been poorly investigated. In the present study, the topic of suicidality was addressed in a clinical, holistic, perspective in an attempt to clarify how, in some chronically ill patients, the decision to end their own life is taken independently from mental disorders, being conversely, the expression of a rational psychological pattern which copes with the burden of chronic illnesses to become an integral part of their clinical spectrum. An assisted suicide (AS) request should therefore be considered from a clinical point of view and not only as an ethical or legal issue, in fact a holistic evaluation of the patient's situation must be performed, conferring the decisions making process a further in-depth line of thinking. In this study we first examined the relationship between suicide and CDTD as reported in the medical literature; then we reviewed the psychological theories which allegedly explain suicidal behavior; finally we discussed the possible role of a full-fledged palliative care in preventing suicide and in managing death requests by CDTD patients.Regular physical activity grants significant health effects and lowers the risk of premature death for all causes, in particular cardiovascular ones in asymptomatic subjects. Physical activity is useful in the primary and secondary prevention of cardiovascular and lung diseases, metabolic diseases, musculoskeletal diseases, cancer and depression. Recent studies correlate inactivity with chronic low-grade inflammation and obesity, at the origin of chronic non-communicable diseases. The evidence must be taken seriously into consideration in this particular CoViD-19 emergency period and long-term effects of prolonged limitation of sports activity must not be overlooked. Contagion in open places is very difficult and the absolute prohibition of sports activities in open places and the closure of parks are creating discomfort and confusion. Institutions and media are generating the wrong message that active people must be looked at with disapproval. Instead, this habit should be encouraged, in order to protect citizens' and community health, lightening the welfare load for society.Italy is one of the most affected countries by the new coronavirus (CoViD-19) pandemic. In the country, there are an estimated 49,000-52,000 homeless people. People experiencing homelessness are among the potentially most vulnerable groups to the CoViD-19. Despite this, in Italy there is a worrying delay in implementation of a national coordinated strategy to protect homeless people from the potentially devastating effects caused by CoViD-19. In order to contain the epidemic among the most vulnerable people, we propose a short operational agenda based on the field experience of the medical-humanitarian organization Medici per i Diritti Umani (Doctors for Human Rights, Italy - MEDU) as well as on the example of initiatives taken by other countries.
