Maackia amurensis seed lectin (MASL) and soluble human podoplanin (shPDPN) sequence analysis and effects on human oral squamous cell carcinoma (OSCC) cell migration and viability.

Maackia amurensis lectins serve as research and botanical agents that bind to sialic residues on proteins. For example, M. amurensis seed lectin (MASL) targets the sialic acid modified podoplanin (PDPN) receptor to suppress arthritic chondrocyte inflammation, and inhibit tumor cell growth and motility. However, M. amurensis lectin nomenclature and composition are not clearly defined. Here, we sought to definitively characterize MASL and its effects on tumor cell behavior. We utilized SDS-PAGE and LC-MS/MS to find that M. amurensis lectins can be divided into two groups. MASL is a member of one group which is composed of subunits that form dimers, evidently mediated by a cysteine residue in the carboxy region of the protein. In contrast to MASL, members of the other group do not dimerize under nonreducing conditions. These data also indicate that MASL is composed of 4 isoforms with an identical amino acid sequence, but unique glycosylation sites. We also produced a novel recombinant soluble human PDPN receptor (shPDPN) with 17 threonine residues glycosylated with sialic acid moieties with potential to act as a ligand trap that inhibits OSCC cell growth and motility. In addition, we report here that MASL targets PDPN with very strong binding kinetics in the nanomolar range. Moreover, we confirm that MASL can inhibit the growth and motility of human oral squamous cell carcinoma (OSCC) cells that express the PDPN receptor. Taken together, these data characterize M. amurensis lectins into two major groups based on their intrinsic properties, clarify the composition of MASL and its subunit isoform sequence and glycosylation sites, define sialic acid modifications on the PDPN receptor and its ability to act as a ligand trap, quantitate MASL binding to PDPN with KD in the nanomolar range, and verify the ability of MASL to serve as a potential anticancer agent.

Decline of tuberculosis notification rate in different populations and regions in Portugal, 2010-2017.

BACKGROUND: Tuberculosis (TB) incidence declined in Portugal in recent decades, but trends differ between regions and population subgroups. We investigated these differences to inform prevention and control programmes. METHODS: We extracted TB notifications from the Portuguese National TB Surveillance System (SVIG-TB) in 2010-2017, disaggregated by region, age group, nationality and HIV status. We calculated notification rates using denominators from the Portuguese National Institute of Statistics and the Joint United Nations Programme on HIV/AIDS and performed stratified time series analysis. We estimated interannual decline percentages and 95% confidence intervals (CI) using Poisson and binomial negative regression models. RESULTS: The overall TB notification rate decreased from 25.7 to 17.5/100,000 population from 2010 to 2017 (5.2%/year) in Portugal. Interannual decline did not differ significantly between regions, but it was smaller amongst non-Portuguese nationals (-1.57% [CI: -4.79%, 1.75%] vs -5.85% [CI: -6.98%, -4.70%] in Portuguese nationals); children under five years of age (+1.77% [CI: -4.61%, 8.58%] vs -5.38% [CI: -6.33%, -4.42%] in other age groups); and HIV-negative people (-6.47% [CI: -9.10%, -3.77%] vs -11.29% [CI; -17.51%, -4.60%] in HIV-positive). CONCLUSIONS: The decline in TB notification rates in Portugal during the study period has been steady. However, the decline amongst non-Portuguese nationals, children under five years of age and non-infected-HIV patients was lower. No significant differences were observed between regions. Changes in TB epidemiology in specific risk groups and geographical areas should be closely monitored to achieve the objectives of the End TB Strategy. We recommend intensifying screening of TB in the subpopulations identified.

Preliminary assessment of the subjective effects of electronic-cigarettes in young-adult low-dose electronic-cigarette users: Effects of nicotine dose and e-liquid flavor.

OBJECTIVE: The present study evaluated the effects of nicotine concentration (0-10 mg/ml) and flavor (gummy bear vs unflavored) on the subjective experiences of vaporized nicotine in young adult low-dose nicotine (3 mg/ml) ECIG users. PARTICIPANTS: Eight young adult ECIG users were recruited. METHODS: A single blinded crossover study was used. Participants were instructed to take ten 1.5 second puffs, each separated by 20 seconds. After self-administration, heart rate was recorded, and participants completed the Drug Effects, Direct Effects of Nicotine, and Direct Effects of ECIG questionnaires. RESULTS: ECIG user's standard daily nicotine dose influenced the rewarding and aversive effects of nicotine as the 10 mg/ml dose was found to be aversive in this user group. The combination of flavor and nicotine increased the subjective effects of ECIGs. CONCLUSIONS: Flavored e-liquids contribute to the reinforcing properties of nicotine by enhancing the subjective effects, which may lead to continued ECIG use.

Estimation of forced vital capacity using speech acoustics in patients with ALS.

In this study, we present and provide validation data for a tool that predicts forced vital capacity (FVC) from speech acoustics collected remotely via a mobile app without the need for any additional equipment (e.g. a spirometer). We trained a machine learning model on a sample of healthy participants and participants with amyotrophic lateral sclerosis (ALS) to learn a mapping from speech acoustics to FVC and used this model to predict FVC values in a new sample from a different study of participants with ALS. We further evaluated the cross-sectional accuracy of the model and its sensitivity to within-subject change in FVC. We found that the predicted and observed FVC values in the test sample had a correlation coefficient of .80 and mean absolute error between .54 L and .58 L (18.5% to 19.5%). In addition, we found that the model was able to detect longitudinal decline in FVC in the test sample, although to a lesser extent than the observed FVC values measured using a spirometer, and was highly repeatable (ICC = 0.92-0.94), although to a lesser extent than the actual FVC (ICC = .97). These results suggest that sustained phonation may be a useful surrogate for VC in both research and clinical environments.

Assessment of antidepressant-like effects of dextromethorphan on differential reinforcement of low-rate 72-s performance in rats.

The effectiveness of ketamine for treatment-resistant depression along with several other clinical advantages, such as rapid onset and reduced adverse effects associated with serotonin transporter inhibition, has garnered interest in other similar acting psychedelics as novel antidepressant drugs. The antitussive dextromethorphan exhibits glutamate N-methyl-d-aspartate receptor antagonism, sigma-1 receptor agonism, and serotonin reuptake inhibition, which has exhibited antidepressant effects in limited human studies and animal models. The present study sought to further examine dextromethorphan using a differential reinforcement of low-rate 72-s schedule, which can be used to screen antidepressant drugs, in male and female rats. The tricyclic antidepressant drug imipramine and the psychostimulant d-amphetamine also were examined. Sex differences were not shown for baseline performance or for the drugs tested. Further, performance did not differ between the estrus and diestrus stages. Dextromethorphan alone and with quinidine produced an antidepressant-like effect by reducing the number of responses emitted, increasing the number of reinforcers earned, and shifting inter-response times to the right, although significant response suppression occurred at these doses. An antidepressant-like effect was shown with imipramine, but d-amphetamine increased the number of responses emitted and did not affect the number of reinforcers earned. The present findings provide additional support for antidepressant effects produced by dextromethorphan.

Nutrient intake and influence on markers of oxidative stress in zoo-managed male snow leopards (Uncia uncia).

Oxidative stress (OS) results from the overproduction of reactive species. Nutrient intake can contribute positively or negatively to OS, and the lack of established nutrient requirements for most of the exotic species managed in zoos exacerbates the possibilities for nutrient imbalances that potentially could lead to reactive species production. The objective of this study was to evaluate the influence of nutrient intake and nutritional husbandry on markers of OS in male snow leopards (n = 14) maintained in U.S. facilities (n = 12). Diet samples and husbandry information were obtained and snow leopards were immobilized once for collection of blood. Samples were analyzed for chemical composition (diet and blood), antioxidant capacity (blood), and markers of OS (blood). Correlations between weekly nutrient intakes and markers of OS were analyzed by linear regression. Analyzed markers of OS included antioxidant enzymes (superoxide dismutase [SOD] and glutathione peroxidase [GPx]) and ferric reducing antioxidant potential that are protective against OS, and protein carbonyls, thiobarbituric acid reactive substances, and DNA/RNA damage that are indicative of oxidative damage. Weekly copper intake (10.1 to 80.2 mg) was negatively correlated with DNA/RNA damage (R 2 = 0.44; P = 0.01). Weekly sodium intake (4.4 to 12.7 g) was positively correlated with GPx activity (R 2 = 0.43; P = 0.04). More frequent feeding of whole prey (0.3 to 3 times/wk) was correlated with increased blood SOD activity (R 2 = 0.55; P < 0.01). In conclusion, greater dietary copper intake and more frequent feeding of whole prey may reduce OS in snow leopards. Dietary sodium intake and relationship with GPx activity should be further evaluated to determine benefit or detriment. No cause and effect can be inferred from our results, but our data suggest altering dietary form and nutrient concentrations may influence OS in snow leopards.

A new health care index predicts short term mortality for TB and HIV co-infected people.

BACKGROUND: Using 2004-2007 TB:HIV Study data from Europe and Latin America, we previously generated a health care index (HCI) for TB and HIV co-infected people. With improvements in diagnostic and management practices, we have now updated the HCI with new data.METHODS: We evaluated nine aspects of health care in Cox proportional hazards models on time from TB diagnosis to death. Kaplan-Meier methods were used to estimate the probability of death by HCI quartile.RESULTS: Of 1396 eligible individuals (72% male, 59% from Eastern Europe), 269 died within 12 months. Use of rifamycin/isoniazid/pyrazinamide-based treatment (HR 0.67, 95% CI 0.50-0.89), TB drug susceptibility testing (DST) and number of active TB drugs (DST + <3 drugs (HR 1.09, 95% CI 0.80-1.48), DST + ≥3 drugs (HR 0.49, 95% CI 0.35-0.70) vs. no DST), recent HIV-RNA measurement (HR 0.64, 95% CI 0.50-0.82) and combination antiretroviral therapy use (HR 0.72, 95% CI 0.53-0.97) were associated with mortality. These factors contributed respectively 5, -1, 8, 5 and 4 to the HCI. Lower HCI was associated with an increased probability of death; 30% (95% CI 26-35) vs. 9% (95% CI 6-13) in the lowest vs. the highest quartile.CONCLUSION: We found five potentially modifiable health care components that were associated with mortality among TB-HIV positive individuals. Validation of our HCI in other TB cohorts could enhance our findings.

[Contact tracing in patients infected with SARS-CoV-2. The fundamental role of Primary Health Care and Public Health]. / Estudio de contactos en infectados por SARS-CoV-2. El papel fundamental de la Atención Primaria y de la Salud Pública.

The aim of this study was to promote the rapid identification of the contacts of patients infected with SARS-CoV-2 and therefore the control of the pandemic. Different methodologies and recommendations on contact tracing for Primary Health Care (PHC) and Public Health Services (PHS), like articles in Pubmed about COVID-19 and contact tracing, official contact definitions, the classic contact tracing model in tuberculosis (TB), information about apps for contact tracing and the role of the diagnostic tests, were reviewed. To establish efficient prevention and control measures, it is always necessary to implement contact tracing based on clinical suspicion, early diagnosis and isolation of cases and contacts and their follow-up. The classic contact tracing model in TB can be applied to this new infection, but accelerating the process given its acute nature and its potential severity. Good coordination between PHC and PHS and having sufficient resources is essential.

Hospital-acquired influenza infections detected by a surveillance system over six seasons, from 2010/2011 to 2015/2016.

BACKGROUND: In addition to outbreaks of nosocomial influenza, sporadic nosocomial influenza infections also occur but are generally not reported in the literature. This study aimed to determine the epidemiologic characteristics of cases of nosocomial influenza compared with the remaining severe cases of severe influenza in acute hospitals in Catalonia (Spain) which were identified by surveillance. METHODS: An observational case-case epidemiological study was carried out in patients aged ≥18 years from Catalan 12 hospitals between 2010 and 2016. For each laboratory-confirmed influenza case (nosocomial or not) we collected demographic, virological and clinical characteristics. We defined patients with nosocomial influenza as those admitted to a hospital for a reason other than acute respiratory infection in whom ILI symptoms developed ≥48 h after admission and influenza virus infection was confirmed using RT-PCR. Mixed-effects regression was used to estimate the crude and adjusted OR. RESULTS: One thousand seven hundred twenty-two hospitalized patients with severe laboratory-confirmed influenza virus infection were included: 96 (5.6%) were classified as nosocomial influenza and more frequently had > 14 days of hospital stay (42.7% vs. 27.7%, P < .001) and higher mortality (18.8% vs. 12.6%, P < .02). The variables associated with nosocomial influenza cases in acute-care hospital settings were chronic renal disease (aOR 2.44 95% CI 1.44-4.15) and immunodeficiency (aOR 1.79 95% CI 1.04-3.06). CONCLUSIONS: Nosocomial infections are a recurring problem associated with high rates of chronic diseases and death. These findings underline the need for adherence to infection control guidelines.

Factors affecting reproductive traits in male snow leopards (Unciauncia).

ABSTRACT: The population of snow leopards (Unciauncia) maintained in US zoos is no longer sustainable due to poor reproductive success. Our objective was to assess reproductive traits in male snow leopards and identify factors (markers of oxidative stress in seminal fluid, surveys of husbandry practices, gonadal and adrenocortical activity, dietary intake of various nutrients, and genetics) that may affect ejaculate traits and subsequent fertility. Ejaculates (2.9 ± 0.2 mL) from 32 male snow leopards (9.8 ± 0.7 years; 38.6 ± 0.8 kg) housed at 27 institutions contained 119.2 + 26.0 x 106 spermatozoa, of which 75.1 ± 2.3% were motile and 28.6 ± 2.6% exhibited normal morphology. Overall, 34% of males produced <5 million spermatozoa and 27% of males produced spermatozoa with <20% normal morphology. Activity of superoxide dismutase (SOD) in the seminal fluid was negatively correlated (P < 0.05, r2 = 0.90) with normal sperm morphology. Husbandry practices, mean concentrations of fecal androgen metabolites (fAM), and baseline concentrations of fecal glucocorticoid metabolites (fGM), inbreeding coefficients, and generations each male was removed from the founders in their lineages were not correlated (P > 0.05) with the total number of spermatozoa or the proportion of spermatozoa with normal morphology. Total sperm count was positively correlated (P < 0.05, R2 = 0.86) with the weekly intake of polyunsaturated fatty acids (PUFA) and the proportion of spermatozoa with normal morphology tended (P < 0.10, R2 = 0.31) to be positively correlated with copper intake. Altering the nutrient composition of snow leopard diets could provide managers with a possible method of improving reproductive traits in this endangered species. LAY SUMMARY: The population of snow leopards (Uncia uncia) maintained in US zoos has been declining since 1993 due to poor breeding success. Our objective was to assess the reproductive traits of male snow leopards and identify factors (e.g. hormones, diet, genetics) that may be affecting the quality of semen produced and therefore subsequent fertility. Within a cohort of 32 male snow leopards maintained at 27 US zoos, we found that 34% produced less than 5 million sperm and 27% of males produced sperm where less than 20% looked normal. The quantity and quality of the recovered sperm was not correlated with husbandry practices, concentrations of hormones (androgens and glucocorticoids) in feces, or genetics. However, the number of sperm was positively correlated with polyunsaturated fatty acids in the diet. Altering the nutrient composition of snow leopard diets could provide managers with a possible method of improving reproductive traits in this endangered species.

Emotional Reactivity as a Vulnerability for Psychogenic Nonepileptic Seizures? Responses While Reliving Specific Emotions.

OBJECTIVE: Dysfunction in emotional processes is a hypothesized contributor to functional neurological disorders (FNDs), yet few studies have evoked real-time emotion during multimethod assessment incorporating subjective, behavioral, and psychophysiological indicators. This approach may reveal clinical and neurobiological vulnerability to FND and clarify how dysfunctional emotional processes serve as perpetuating factors. METHODS: Eleven participants with video-EEG-confirmed diagnoses of psychogenic nonepileptic seizures (PNES) were compared with 49 seizure-free trauma control subjects (TCs) with or without clinically elevated posttraumatic stress symptoms (25 clinically elevated [TC-clin], 24 not clinically elevated [TC-nonclin]). Participants recalled and described memories evoking anger, shame, happiness, and neutral feelings. RESULTS: Even though PNES patients and TCs reported similar amounts of emotional experience, PNES patients reported more difficulty reliving emotions and were less likely to complete the relived shame task. During and after reliving happiness, PNES and TC-clin groups showed respiratory sinus arrhythmia (RSA) decreases, indicating parasympathetic withdrawal, whereas the TC-nonclin group showed RSA increases. CONCLUSIONS: Findings from this pilot study are consistent with previous research and clinical observations that emotional engagement may be more effortful for PNES patients. Patterns of RSA change, which may also point to greater effortful engagement, were similar in PNES and TC-clin groups, suggesting that traumatic stress reactions may play a part. At the same time, experience of greater difficulty or avoidance may be even greater among PNES patients. Especially when regulatory resources are already limited, accumulated effort, coupled with self-threatening contexts such as shame, may be particularly problematic for those with PNES and perhaps other FNDs.

Is it possible to eliminate hepatitis C from the prisons of Catalonia, Spain, in 2021?

AIM: Predict the elimination of chronic hepatitis C in Catalan prisons. MATERIAL AND METHOD: We analyzed the trend of the prevalence of HCV-RNA and anti-hepatitis C treatments prescribed in Catalonia in the period 2002-2016. Using linear exponential smoothing from the historical values in the time series, we estimate the time required to eliminate hepatitis C as a public health problem in prisons (prevalence of hepatitis C virus RNA<1%). RESULTS: A total of 1264 treatments were administered by 12/31/2016. The prevalence of hepatitis C virus RNA was 31.2% in 2002, decreasing to 8.81% in 2016. We estimate that prevalence will reach 0-0.5% in 5 years (second half 2021; 95% CI: 2019-2025). DISCUSSION: Appropriate actions can eliminate hepatitis C infection in prisoners. We estimate that by 2021 hepatitis C infection will no longer be a public health problem in Catalonia prisons.

Social Participation of Burn Survivors and the General Population in Work and Employment: A Life Impact Burn Recovery Evaluation (LIBRE) Profile Study.

INTRODUCTION: Work integration and retention after burn injury is a key outcome. Little is known about how burn survivors reintegrate into the workplace. This article compares scores on the Life Impact Burn Recovery Evaluation (LIBRE) Profile, a burn-specific measure of social participation, between burn survivors and general population samples, focusing on the Work and Employment domain. METHODS: Convenience samples of burn survivors and the U.S. population were obtained. Differences in demographic and clinical characteristics and LIBRE Profile scores were assessed. To examine work and employment, we compared family and friends, social activities, and social interactions scores among working vs nonworking burn survivors. RESULTS: Six hundred and one burn survivors (320 employed) and 2000 U.S. residents (1101 employed) were surveyed. The mean age (P = .06), distributions of sex (P = .35), and Hispanic ethnicity (P = .07) did not differ significantly. Distributions of race (P < .01) and education (P = .01) differed significantly. The burn survivor sample had higher scores, demonstrating higher participation, for work and employment (mean = 49.5, SD = 9.42) than the general sample (mean = 46.94, SD = 8.94; P < .0001), which persisted after adjusting for demographic characteristics. Scores on the three domains administered to all respondents were higher (P < .001) for working than nonworking burn survivors. CONCLUSION: Distributions indicated higher social participation in the burn survivor sample than the general sample. Possible explanations include sample bias; resilience, posttraumatic growth, or response-shift of survivors; and limitations of using items in the general sample. Working burn survivors scored higher than those not working. Future work can explore factors that mediate higher scores and develop interventions.

Impact of socio-economic inequities on tuberculosis in a Southern European city: what is the effect of the recession?

INTRODUCTION: Economic crises affect a population's health, particularly among the most deprived. The increase in health inequalities in the latest recession may have influenced the incidence of tuberculosis (TB). We analysed the effect of socio-economic inequities and recession on TB incidence in Barcelona, Spain. METHODS: We conducted a population-based incidence study of TB cases in Barcelona of patients who started treatment between 2003 and 2015. A multilevel interrupted time-series analysis was performed to analyse differences in incidence trends between the pre-recession (until 2008) and recession periods. RESULTS: We found differences in TB incidence according to deprivation and immigration status. TB incidence among the most deprived neighbourhoods was 2.72 times higher than the least deprived neighbourhoods. Compared with native-born persons, incidence was nine times higher among those born in Africa, and six times higher among those born in Asia and Oceania. The previous decreasing trend in incidence (4%) was accentuated during the recession (7%). CONCLUSIONS: TB incidence decreased during the recession, probably due to a reduction in the number of new immigrants and the TB programme. However, incidence was highly unequal between districts with different levels of deprivation, and between foreign-born persons from different geographic regions. Social measures are important to reduce inequalities and TB incidence in Barcelona.

Diagnostic utility of the Minnesota Multiphasic Personality Inventory-2 Restructured Form in the epilepsy monitoring unit: Considering sex differences.

Psychological assessment measures are frequently used to evaluate patients in epilepsy monitoring units. One goal of that assessment is to contribute information that may help with differential diagnosis between epilepsy and psychogenic nonepileptic seizures (PNES). The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) is one such measure. Del Bene et al. (2017) recently published an analysis that was the first to compare MMPI-2-RF scale elevations between diagnostic groups stratified by sex. The purpose of the present study was to replicate that analysis in a larger sample. Similar to previous work, we found that both men and women with PNES were more likely than men and women with epilepsy to report high levels of somatic complaints (2 to 5 times greater odds of somatic symptom reporting) and a variety of types of complaints. Mood disturbance scales were not significantly elevated in our PNES sample. Results contribute to the small body of research on sex differences in patients with PNES and suggest that somatization is a key characterization across sexes.

Nutrient evaluation of a pork by-product and its use as environmental enrichment for managed large exotic cats.

North American zoological institutions typically feed ground raw meat diets to large exotic cats. These diets typically are nutritionally complete, but lack physical properties characteristic of whole prey. Lack of mastication and prey manipulation may contribute to behavioral and health challenges. Pork by-products may provide environmental enrichment to mitigate these challenges. The objectives of this study were to evaluate a pig head for nutritional composition and to determine if a pig head was biologically relevant environmental enrichment for managed large exotic cats. Pig heads consisted of: DM: 48.5%; OM: 60.7%; CP: 38.4%; fat: 22.0%; CF: 13.5%; TDF: 3.4%; GE: 4.1 kcal/g DM. Five individually housed exotic cats (Panthera tigris tigris, Panthera tigris altaica (n = 2), Panthera tigris jacksoni, Panthera leo) were observed in 2-h blocks, 24-h before pig head introduction (Baseline), at time of pig head introduction (Enrichment) and immediately after the pig head was removed (Post Enrichment) via instantaneous scan sampling for 4 consecutive weeks. Active behaviors were 55.7% higher on Enrichment compared to Baseline days, and 26.4% higher compared to Post Enrichment days (p<0.0001). Active behaviors were 39.8% higher on Post Enrichment compared to Baseline days (p<0.0001). Total active behaviors were highest (p<0.0001) in week 3 and lowest (p<0.0001) in week 4 with differences as high as 64.5% seen among weeks. In conclusion, pig heads have potential to provide nutrient dense enrichment to large exotic cats, and employing a pig head as environmental enrichment increased active behaviors and did not lose novelty.

Capture-recapture and anti-tuberculosis drug prescriptions, Balearic Islands, Spain, 2010-2012.

SETTING: Tuberculosis (TB) control requires accurate knowledge of TB incidence, but few studies have been published on TB incidence using individual data from drug prescriptions. OBJECTIVE: To measure the estimated completeness of regional surveillance system data before and after adding data from anti-tuberculosis drug prescriptions. DESIGN: We compiled data on all individuals who received specific anti-tuberculosis drugs from three sources-the passive surveillance system, the active surveillance system and the anti-tuberculosis drug prescription database-in the Balearic Islands, Spain, between 2010 and 2012. We applied the capture-recapture method to measure completeness of data reporting. Statistical significance was set at P < 0.05, and 95% confidence intervals (CIs) were calculated. RESULTS: We detected 605 incident cases, compared with an estimated incidence of 719 cases (95%CI 646-793), representing 84.1% data completeness. We detected 480 of an estimated 559 pulmonary TB cases (95%CI 501-617; 85.9% data completeness) and 125 of an estimated 161 extra-pulmonary TB cases (95%CI 113-211; 77.6% data completeness). CONCLUSIONS: By adding a new source, we increased detection with respect to a previous study by 10.4% for all forms of TB, 9.7% for pulmonary TB and 13% for extra-pulmonary TB.

Effectiveness of antiviral treatment in preventing death in severe hospitalised influenza cases over six seasons.

We investigated the predictors of neuraminidase inhibitor (NAI) treatment in severe hospitalised influenza cases and the association between antiviral treatment and mortality. An observational epidemiological study was carried out in Catalonia (Spain) during 2010-2016 in patients aged ⩾18 years. Severe hospitalised cases of laboratory-confirmed influenza requiring hospitalisation were included. We collected demographic, virological and clinical characteristics. Mixed-effects logistic regression was used to estimate crude and adjusted odds ratio (aOR). We included 1727 hospitalised patients, of whom 1577 (91.3%) received NAI. Receiving NAI ⩽48 h after onset of clinical symptoms (aOR 0.37, 95% confidence interval (CI) 0.22-0.63), ⩽3 days (aOR 0.49, 95% CI 0.30-0.79) and ⩽5 days (aOR 0.50, 95% CI 0.32-0.79) was associated with a reduction in deaths. In patients admitted to the intensive care unit (ICU) (595; 34.5%), treatment ⩽48 h (aOR 0.32, 95% CI 0.14-0.74), ⩽3 days (aOR 0.44, 95% CI 0.20-0.97) and ⩽5 days (aOR 0.45, 95% CI 0.22-0.96) was associated with a reduction in deaths. Receiving treatment >5 days after onset of clinical symptoms was not associated with the reduction in deaths in hospitalised patients or those admitted to the ICU. NAI treatment of hospitalised patients with severe confirmed influenza was effective in avoiding death, mainly when administered ⩽48 h after symptom onset, but also when no more than 5 days had elapsed.

Management of MDR-TB in HIV co-infected patients in Eastern Europe: Results from the TB:HIV study.

OBJECTIVES: Mortality among HIV patients with tuberculosis (TB) remains high in Eastern Europe (EE), but details of TB and HIV management remain scarce. METHODS: In this prospective study, we describe the TB treatment regimens of patients with multi-drug resistant (MDR) TB and use of antiretroviral therapy (ART). RESULTS: A total of 105 HIV-positive patients had MDR-TB (including 33 with extensive drug resistance) and 130 pan-susceptible TB. Adequate initial TB treatment was provided for 8% of patients with MDR-TB compared with 80% of those with pan-susceptible TB. By twelve months, an estimated 57.3% (95%CI 41.5-74.1) of MDR-TB patients had started adequate treatment. While 67% received ART, HIV-RNA suppression was demonstrated in only 23%. CONCLUSIONS: Our results show that internationally recommended MDR-TB treatment regimens were infrequently used and that ART use and viral suppression was well below the target of 90%, reflecting the challenging patient population and the environment in which health care is provided. Urgent improvement of management of patients with TB/HIV in EE, in particular for those with MDR-TB, is needed and includes widespread access to rapid TB diagnostics, better access to and use of second-line TB drugs, timely ART initiation with viral load monitoring, and integration of TB/HIV care.
