To analyze the antibiotic prescription rate in low-risk patients evaluated at a telemedicine program that adopts antibiotic stewardship protocols.

Adult patients who accessed a single direct-to-consumer telemedicine center (Jan/2019-Feb/2020) were retrospectively enrolled. Diseases amenable to antimicrobial treatment were classified under five diagnostic groups upper respiratory tract infection (URI), acute pharyngotonsillitis (PT), acute sinusitis (AS), urinary tract infection (UTI), and acute diarrhea (AD). Physicians were trained on and advised to strictly follow the current guideline recommendations supported by institutional antibiotic stewardship protocols, readily available online during consultations. We analyzed the antibiotic prescription rate among patients, referral rate, and antibiotic class through descriptive statistics.

A total of 2328 patients were included in the study. 8-OH-DPAT chemical structure A total of 2085 (89·6%) patients were discharged with usual recommendations, medication (if needed), and instructions about red flags, while 243 (10·4%) were referred to a face-to-face consultation. Among the discharged patients, the antibiotic prescription rates by the diagnostic group were URI - 2·5%, PT - 35·0%, AS - 51·8%, UTI - 91.6%, and AD - 1·6%. In most cases, prescribed antibiotics were in line with institutional stewardship protocols.

Low prescription rate of antibiotics can be achieved using antibiotic stewardship protocols at direct-to-consumer telemedicine consultations, showing high adherence to international guidelines. These results reinforce telemedicine as a cost-effective and safe strategy for the initial assessment of acute non-urgent symptoms.

In 2019, the World Health Organization (WHO) flagged vaccine hesitancy as one of the top 10 threats to global health. The drivers of and barriers to under-vaccination include logistics (access to and awareness of affordable vaccines), as well as a complex mix of psychological, social, political, and cultural factors.

There is a need for effective strategies to increase vaccine uptake in various settings, based on the best available evidence. Fortunately, the field of vaccine acceptance research is growing rapidly with the development, implementation, and evaluation of diverse measurement tools, as well as interventions to address the challenging range of drivers of and barriers to vaccine acceptance.

Since 2011, the Mérieux Foundation has hosted Annual Vaccine Acceptance Meetings in Annecy, France that have fostered an informal community of practice on vaccination confidence and vaccine uptake. Mutual learning and sharing of knowledge has resulted directly in multiple initiatives and research projects. es, vaccine acceptance and demand, training on vaccine acceptance, and frameworks for resilience of vaccination programmes.

In this study, we determined the accuracy of anti-Leishmania IgG and IgG subclasses to distinguish clinical forms of American tegumentary leishmaniasis (ATL) and and determined the relationship between antibodies levels with cytokine production and severity of ATL.

Participants were 40 patients with cutaneous leishmaniasis (CL), 20 patients with mucosal leishmaniasis (ML), 20 patients with disseminated leishmaniasis (DL), and 20 individuals with subclinical Leishmania braziliensis infection (SC). Diagnosis was performed by DNA of L. braziliensis or IFN-γ production in SC. IgG and subclasses of IgG to soluble Leishmania antigen and cytokine levels in supernatants of mononuclear cells were detected by ELISA.

IgG was detected in 95%, 95%, and 100% of patients with CL, ML, and DL, respectively. Higher levels of anti-Leishmania IgG and IgG2 were seen in DL compared to CL, ML, and SC. ROC analysis confirmed the ability of IgG to distinguish DL from the other clinical forms. A direct correlation was observed between IgG titers and levels of IFN-γ and CXCL10 in CL and DL, and IgG2 antibodies were correlated with the number of lesions in DL.

High anti-Leishmania IgG and IgG2 levels are characteristic of DL, and while IgG was correlated with pro-inflammatory cytokines, IgG2 was direct correlated with the number of lesions.

Surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among sheltered homeless and other vulnerable people might provide the information needed to prevent its spread within accommodation centres.

Data were obtained from 698 participants in different accommodation centres (411 homeless individuals, 77 asylum-seekers, 58 other people living in precarious conditions and 152 employees working in these accommodation centres) who completed questionnaires and had nasal samples collected between 26 March and 17 April 2020. SARS-CoV-2 carriage was assessed by quantitative PCR.

We found a high acceptance rate (78.9%) for testing. Overall, 49 people (7.0%) were positive for SARS-CoV-2, including 37 homeless individuals (of 411, 9.0%) and 12 employees (of 152, 7.9%). SARS-CoV-2 positivity correlated with symptoms, although 51% of patients who tested positive did not report respiratory symptoms or fever. Among homeless people, being young (18-34 years) (odds ratio 3.83, 95% confidence interval 1.47-10.0, p = 0.006) and being housed in one specific shelter (odds ratio 9.13, 95% confidence interval 4.09-20.37, p < 0.001) were independent factors associated with SARS-CoV-2 positivity (rates of 11.4% and 20.6%, respectively).

Symptom screening alone is insufficient to prevent SARS-CoV-2 transmission in vulnerable sheltered people. Systematic testing should be promoted.

COVID-19 has grown rapidly across the world. Tunisia reacted early to COVID-19 resulting in low number of infections. In this paper we model the effects of different interventions on the evolution of cases and compare this to the Tunisian experience.

We use a stochastic transmission model to quantify the reduction in number of cases of COVID-19 of interventions of contact tracing, compliance with isolation and a general lockdown.

Increasing contact tracing from 20% to 80% after the first 100 cases reduces the cumulative number of infections (CNI) by 52% in one month. Similarly, increased compliance to isolation from 20% to 80% after the first 100 cases reduces the CNI by 45%. These reductions are smaller if the interventions are implemented after 1000 cases. A general lockdown reduces the CNI by 97% after the first 100 cases. Tunisia implemented its general lockdown after 75 cases were confirmed, reduced the cumulative number of infected cases by 86% among the general population.

This study shows that early application of critical interventions contributes to significantly reducing infections and the evolution of COVID-19 in a country. Tunisia's early success with control of COVID-19 is explained by its quick response.

The PubMed, Google Scholar, Embase, Scopus, Clinicaltrials.gov, and International Clinical Trials Registry Platform databases were systematically searched for the following keywords respiratory tract infection, probiotics, viral infection, COVID-19, and clinical trial. A total of 27 clinical trials conducted on 9433 patients with RTI plus 10 ongoing clinical studies of probiotics intervention in Coronavirus disease 2019 (COVID-19) were reviewed. The review looked at the potency of probiotics for the hindrance and/or treatment of RTI diseases, this may also apply to COVID-19. The review found that probiotics could significantly increase the plasma levels of cytokines, the effect of influenza vaccine and quality of life, as well as reducing the titer of viruses and the incidence and duration of respiratory infections. These antiviral and immune-modulating activities and their ability to stimulate interferon production recommend the use of probiotics as an adjunctive therapy to prevent COVID-19. Based on this extensive review of RCTs we suggest that probiotics are a rational complementary treatment for RTI diseases and a viable option to support faster recovery.

To evaluate the role of eggs and other food vehicles as risk factors associated with Salmonella enteritidis (SE) outbreaks in order to address the endemicity of SE infections in the USA.

We retrieved and analyzed data relating to all SE outbreaks reported to the Centers for Disease Control and Prevention (CDC) between 1990 and 2015. We then used descriptive and analytical statistical methods, including negative binomial regression models for the estimation of rate-ratios, to analyze the data.

Analyses showed that egg-based dishes were the most common food vehicle associated with outbreaks of SE in the USA (273 cases [24%]); this was followed by several other food items, including meat (130 cases [11%]), vegetables (96 cases [8%]), chicken items (95 cases [8%]), dairy products (55 cases [5%]), and bakery items (8 cases [1%]). Compared to egg-based dishes, other food items such as meat (exp(β) = 0.51, 95% CI 0.37, 0.69), chicken (exp(β) = 0.42, 95% CI 0.30, 0.58), vegetables (exp(β) = 0.41, 95% CI 0.29, 0.55), and dairy items (exp(β) = 0.27, 95% CI 0.18, 0.40) were significantly associated with outbreaks of SE in the USA. Of 1144 SE outbreaks, 402 (35%) occurred in the Northeast region of the USA, followed by the South (253 [22%]), West (250 [22%]), and Midwestern regions (239 [21%]).

Epidemiological and spatiotemporal trends analyses demonstrated that a significant proportions of Salmonella enteritidis outbreaks in the USA are attributed to food vehicles other than eggs. Our findings can be used to plan effective strategies to mitigate the increasing occurrence of foodborne SE outbreaks.

To determine the duration of SARS-CoV-2 persistence in quarantine hotel environments.

39 Patients confirmed by RT-PCR were included. We collected clinical features, laboratory test results, smear sample information, and quarantine room information. Genome sequencing and phylogenetic analysis were conducted. We analyzed the factors associated with environmental contamination.

Among 39 COVID-19 cases, 10 were asymptomatic and 37 were imported from aboard. We collected 271 swab samples from environmental surfaces related to observational patients. Eighteen swab samples from seven patients were positive. The highest contamination rates occurred on cups (100%), followed by hand sink (12.82%), toilet seat and flush (7.89%), telephone (5.56%), bedside table (5.56%), and floor drain (5.41%). The results showed that environmental surface contamination was associated with the clinical cycle threshold values for patients (P = 0.01) and the sampling interval time after the cases left their rooms (P = 0.03). The duration of environmental surface contamination was associated with the wet status of the sampling site (P = 0.
