RESUMO
OBJECTIVE: To analyze the psychological and functional sequelae of the COVID-19 pandemic among older adults living in long term care facilities (LTCFs). DESIGN: Cohort longitudinal study SETTING ANT PARTICIPANTS: A total of 215 residents ≥ 65 years without moderate-to-severe cognitive impairment, living in five LTCFs in Albacete (Spain). MEASUREMENTS: Baseline on-site data were collected between March - June 2020 and three-month follow-up between June to September 2020. Symptoms of depression, anxiety, posttraumatic stress disorder (PTSD), and sleep disturbances were measured as psychological variables. Disability in basic activities of daily living (BADL), ambulation and frailty were assessed as functional variables. Differences were analyzed in relation to level of comorbidity and test positivity for COVID-19. RESULTS: At baseline, residents with COVID-19 presented worse functionality, higher frailty levels and malnutrition risk compared to non-COVID-19 residents. At three-month follow-up, higher rates of clinically significant depressive symptoms (57.7%), anxiety symptoms (29.3%), PTSD symptoms (19.1%) and sleep disturbances (93.0%) were found among residents regardless of COVID status. Thus, among 215 residents, 101 (47%) experienced a decline in BADL from baseline to the 3-month follow-up (median functional loss = 5 points in Barthel Index). In multivariate analyses, COVID-19 status did not explain either the functional or the ambulation loss. By contrast, residents with low comorbidity and COVID-19 presented higher PTSD symptoms (effect 2.58; 95% CI 0.93 to 4.23) and anxiety symptoms (effect 2.10; 95% CI 0.48 to 3.73) compared to the low comorbidity/non-COVID19 group. CONCLUSION: COVID-19 pandemic was associated, after three-months, with high psychological impact in older adults in LTCFs., specifically with higher post-traumatic stress and anxiety symptoms. Functional decline did not differ in relation to COVID-19 status but could be related to isolation strategies used for pandemic control.

BACKGROUND: The gut microbiota is a significant reservoir of antimicrobial resistance genes (ARGs). The use and misuse of antimicrobials can select multi-resistant bacteria and modify the repertoire of ARGs in the gut. Developing effective interventions to manipulate the intestinal resistome would allow us to modify the antimicrobial resistance risk. MATERIALS AND METHODS: Applying shotgun metagenomics, we compared the composition of fecal resistome from individuals treated with triple therapy for Helicobacter pylori plus Saccharomyces boulardii CNCM-I 745 (Sb) versus triple antibiotherapy without S. boulardii (control) before, after, and one month after treatments. DNA samples were sequenced on an Illumina NovaSeq 6000 platform. Reads were trimmed and filtered for quality, and the reads classified as host genome were removed from further analysis. We used the ResFinder database for resistome analysis and the web-based tool ResistoXplorer and RStudio for graphical representation and statistical analysis. RESULTS: We identified 641 unique ARGs in all fecal samples, conferring resistance to 18 classes of antibiotics. The most prevalent ARGs found in at least 90% of the samples before the treatments were against tetracyclines, MLS-B (macrolide, lincosamide, and streptogramin B), beta-lactams, and aminoglycosides. Differential abundance analysis allowed the identification of ARGs significantly different between treatment groups. Thus, immediately after the treatments, the abundance of ARGs that confer resistance to lincosamides, tetracyclines, MLS-B, and two genes in the beta-lactam class (cfxA2 and cfxA3) was significantly lower in the group that received Sb than in the control group (edgeR, FDR <0.05). CONCLUSION: Our study demonstrated that the addition of S. boulardii CNCM-I 745 to the conventional antibiotic eradication therapy for H. pylori reduced the abundance of ARGs, particularly those genes that confer resistance to lincosamides, tetracyclines, MLS-B, and a few genes in the beta-lactams class.

OBJECTIVE: To respond to the World Health Assembly call for dissemination of lessons learnt from countries that have begun implementing the International Health Regulations, 2005 revision; IHR (2005). METHODS: In November 2015, we conducted a systematic search of the following online databases and sources: PubMed®, Embase®, Global Health, Scopus, World Health Organization (WHO) Global Index Medicus, WHO Bulletin on IHR Implementation and the International Society for Disease Surveillance. We included identified studies and reports summarizing national experience in implementing any of the IHR (2005) core capacities or their components. We excluded studies that were theoretical or referred to IHR (1969). Qualitative systematic review methodology, including meta-ethnography, was used for qualitative synthesis. FINDINGS: We analysed 51 articles from 77 countries representing all WHO Regions. The meta-syntheses identified a total of 44 lessons learnt across the eight core capacities of IHR (2005). Major themes included the need to mobilize and sustain political commitment; to adapt global requirements based on local sociocultural, epidemiological, health system and economic contexts; and to conduct baseline and follow-up assessments to monitor the status of IHR (2005) implementation. CONCLUSION: Although experiences of IHR (2005) implementation covered a wide global range, more documentation from Africa and Eastern Europe is needed. We did not find specific areas of weakness in monitoring IHR (2005); sustained monitoring of all core capacities is required to ensure effective systems. These lessons learnt could be adapted by countries in the process of meeting IHR (2005) requirements.

Colistin is one of the last-line treatments for multi-drug resistant Gram-negative bacterial infections. The emergence of mobile colistin resistance genes has driven global concern and triggered the need for surveillance. Our report reveals the identification of mcr-9.1 and mcr-10.1 in Ecuador by employing a proximity ligation technique.
RESUMO
In tropical areas, the predominant cause of fever has historically been malaria. However by 2011, among febrile patients in northwestern Ecuador, dengue was identified in 42% and malaria in none. This finding suggests a transition in the cause of fever from malaria to other illnesses, such as dengue.

OBJECTIVES: The paediatric gut microbiota is a reservoir of antimicrobial resistance genes. Environmental factors such as a child's exposure to faecal contamination and antimicrobial resistance genes of animal origin likely shape the resistome of infants and children. This study measured how different levels of exposure to domestic or food animals affect the structure of the intestinal resistome in children between 1 and 7 years of age. METHODS: One hundred nineteen faecal samples from 39 children were analysed according to the level of exposure to domestic or food animals and categorized into three risk groups. Using high-throughput sequencing with an Illumina NovaSeq 6000 SP platform, we performed faecal resistome analyses using the ResFinder database. Additionally, ResistoXplorer was used to characterize the resistomes of children differentially exposed to domestic animals. RESULTS: Our data indicated that specific antimicrobial resistance genes such as those that confer resistance to MATFPR (macrolide, aminoglycoside, tetracycline, fluoroquinolone, phenicol, and rifamycin) and tetracyclines were statistically less abundant in the group of children without exposure to animals (group 2), compared with the groups exposed to domestic and food animals (groups 1 and 3). However, the overall resistome structure among the children was not affected by the different levels of exposure to animals. CONCLUSIONS: This study suggests that animal exposure is a risk factor for young children acquiring specific antimicrobial resistance genes from domestic animals or animal production areas. However, the overall resistome structure was not affected.

INTRODUCTION: Objective: to describe the nutritional status of older adults hospitalized in an acute geriatric unit (AGU) and its association with mortality and days of hospitalization. Material and methods: a retrospective study in 1,084 adults older than 65 years, hospitalized in an AGU. The Mini Nutritional Assessment®-Short Form (MNA®-SF) and subjective global assessment (SGA) were used. The association between nutritional status, mortality, and long hospital stay (> 7 days) was analyzed using regression models and Cox hazard models. Results: mean age was 86.5 years: 58.7% were women. Mean MNA®-SF score was 8.9 (20.0%, well nourished; 48.2%, at nutritional risk, and 31.7% with malnutrition). Using the SGA, 22.1% were well nourished, 54.7% had moderate malnutrition, and 23.2% had severe malnutrition. Agreement between SGA and MNA®-SF was good (kappa, 0.654; p < 0.001), and correctly classified 78.5% of participants. Malnutrition was associated with poorer cognitive status, greater disability, worse ambulation, and lower levels of total protein, albumin, cholesterol, and transferrin. Patients with malnutrition in the MNA®-SF assessment had a higher adjusted mortality risk than those who were well nourished (HR, 1.80; 95% CI, 1.01-3.20), same as those with SGA C versus A (HR, 1.66; 95% CI, 0.96-2.86). Patients with SGA B and C presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.42; 95% CI, 1.04-1.96 and OR, 1.73; 95% CI, 1.18-2.54, respectively. Patients with malnutrition per the MNA-SF® presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.59; 95% CI, 1.09-2.33). Conclusions: nutritional risk and malnutrition are very common in older adults in AGUs, and are associated with higher mortality and longer hospital stay.
INTRODUCCIÓN: Objetivo: describir el estado nutricional de los mayores hospitalizados en una unidad geriátrica de agudos (UGA) y su asociación con la mortalidad y la estancia hospitalaria. Material y métodos: estudio retrospectivo de 1084 personas mayores de 65 años en una UGA. Se emplearon el Mini Nutritional Assessment®-Short Form (MNA®-SF) y la valoración global subjetiva (VGS). La asociación entre estado nutricional, mortalidad y estancia hospitalaria prolongada (> 7 días) se analizó mediante un modelo de regresión y el análisis de riesgos de Cox. Resultados: edad media de 86,5 años: 58,7% de mujeres. La puntuación media del MNA®-SF fue de 8,9, estando el 20,0% sin riesgo nutricional, el 48,2% en riesgo nutricional y el 31,7% con malnutrición. Mediante la VGS, el 22,1% estaban bien nutridos, el 54,7% moderadamente desnutridos y el 23,2% gravemente desnutridos. El acuerdo entre VGS y MNA®-SF fue bueno (kappa = 0,654; p < 0,001), clasificando correctamente al 78,5% de los participantes. La malnutrición se asoció a peor estado cognitivo, mayor discapacidad, peor deambulación y niveles menores de proteínas totales, albúmina, colesterol y transferrina. Los pacientes con malnutrición según el MNA®-SF presentaron una mortalidad ajustada mayor que la de los bien nutridos (HR: 1,80; IC 95%: 1,01-3,20), igual que aquellos con VGS de C frente a los de A (HR: 1,66; IC 95%: 0,96-2,86). Los pacientes con VGS de B (OR: 1,42; IC 95%: 1,04-1,96) y C (OR: 1,73; IC 95%: 1,18-2,54) presentaron mayor riesgo ajustado de estancia hospitalaria prolongada frente a los bien nutridos. Los pacientes con malnutrición según el MNA®-SF presentaron mayor riesgo ajustado de estancia hospitalaria prolongada (OR: 1,59; IC 95%: 1,09-2,33) frente a los bien nutridos. Conclusiones: el riesgo nutricional y la malnutrición son muy frecuentes en los mayores hospitalizados en una UGA y se asocian con mayor mortalidad y estancias más prolongadas.

BACKGROUND/OBJECTIVES: To analyze mortality, costs, residents and personnel characteristics, in six long-term care facilities (LTCF) during the outbreak of COVID-19 in Spain. DESIGN: Epidemiological study. SETTING: Six open LTCFs in Albacete (Spain). PARTICIPANTS: 198 residents and 190 workers from LTCF A were included, between 2020 March 6 and April 5. Epidemiological data were also collected from six LTCFs of Albacete for the same period of time, including 1,084 residents. MEASUREMENTS: Baseline demographic, clinical, functional, cognitive and nutritional variables were collected. 1-month and 3-month mortality was determined, excess mortality was calculated, and costs associated with the pandemics were analyzed. RESULTS: The pooled mortality rate for the first month and first three months of the outbreak were 15.3% and 28.0%, and the pooled excess mortality for these periods were 564% and 315% respectively. In facility A, the percentage of probable COVID-19 infected residents were 33.6%. Probable infected patients were older, frail, and with a worse functional situation than those without COVID-19. The most common symptoms were fever, cough and dyspnea. 25 residents were transferred to the emergency department, 21 were hospitalized, and 54 were moved to the facility medical unit. Mortality was higher upon male older residents, with worse functionality, and higher comorbidity. During the first month of the outbreak, 65 (24.6%) workers leaved, mainly with COVID-19 symptoms, and 69 new workers were contracted. The mean number of days of leave was 19.2. Costs associated with the COVID-19 in facility A were estimated at 276,281/month, mostly caused by resident hospitalizations, leaves of workers, staff replacement, and interventions of healthcare professionals. CONCLUSION: The COVID-19 pandemic posed residents at high mortality risk, mainly in those older, frail and with worse functional status. Personal and economic costs were high.

BACKGROUND: Staphylococcus aureus is a common nasal colonizer in 20-30% of the general population. When mucosal and cutaneous barriers are disrupted, S. aureus can cause severe infections. While MRSA nasal carriers have an increased risk of infections when compared to non-carriers, prolonged exposure to the hospital environment may cause an increase in carriage of MRSA. MATERIALS AND METHODS: A survey questionnaire was filled for analyzing risk factors of colonization. Swab isolates were identified as S. aureus by traditional microbiological assays. Antibiotic susceptibility profiles were performed following the CLSI standard guidelines. Multiplex PCR was conducted to determine the presence of genes mecA and lukS-PV/lukF-PV. Chi-squared, univariate, and multivariate logistic regressions were applied to find statistically significant associations between risk factors and the presence of S. aureus and MRSA. RESULTS: One hundred and eighty-six isolates were identified as S. aureus. The strains showed high resistance to penicillin, oxacillin, azithromycin, erythromycin, clindamycin (inducible), and tetracycline. The overall prevalence of MRSA in medical students was 45.9% [40.4-51.6] 95% CI. PCR showed a prevalence of mecA gene in MRSA isolates of 6.1% while lukS-PV/lukF-PV gene was present in 3.2% [1.2-6.9] 95% CI of the S. aureus samples. The risk factors frequency of antibiotic intake and repeated visits to hospitals demonstrated statistical significance. CONCLUSION: S. aureus and MRSA isolates have a high prevalence of colonization, and antibiotic resistance in the population studied. MRSA resistance was not related to the presence of the mecA gene. The prevalence of PVL genes was low, but it could represent a risk because they are circulating in the community.
RESUMO
Microscopic examination is the standard method for diagnosis of cutaneous and mucocutaneous leishmaniasis despite its low sensitivity. This study compared the diagnosis efficacy of microscopic examination versus polymerase chain reaction (PCR)-based methods and DNA sequencing using whole blood and skin lesion samples from patients with suspected leishmaniasis. The presence of Leishmania was determined by microscopy and amplification of 18S ribosomal RNA gene from blood and skin samples of 22 patients. Twenty individuals were positive for leishmaniasis. Microscopic analysis identified 85%, whereas PCR identified 100% of positive cases from skin and 90% from blood. Cytochrome b gene (cyt-b) amplification and sequencing identified Leishmania guyanensis, Leishmania shawi, and Leishmania naiffi from skin and blood samples. This study demonstrated the usefulness of whole blood and molecular techniques for the diagnosis and species identification of leishmaniasis.
