Abstract
In this systematic review, we aimed to assess the efficacy and safety of nonsteroidal anti-inflammatory drugs (NSAIDs) in treating respiratory tract infections in adults and children. PubMed, Scopus, Web of Science, Cochrane, and Embase databases were searched. A total of 34 randomized clinical trials were included in this systematic review. We assessed the risk of bias of all included studies using the Cochrane tool for risk of bias assessment. The evidence on ibuprofen, naproxen, aspirin, diclofenac, and other NSAIDs were rated for degree of uncertainty for each of the study outcomes and summarized using the grading of recommendations assessment, development, and evaluation (GRADE) approach. Our findings suggest that high-quality evidence supports the use of NSAIDs to reduce fever in both adults and children. However, the evidence was uncertain for the use of NSAIDs to reduce cough. Most studies showed that NSAIDs significantly relieved sore throat. The evidence for mortality and oxygenation is limited. Regarding the adverse events, gastrointestinal discomfort was more frequently reported in children. For adults, our overall certainty in effect estimates was low and the increase in gastrointestinal adverse events was not clinically significant. In conclusion, NSAIDs seem to be beneficial in the outpatient management of fever and sore throat in adults and children. Although the evidence does not support their use to decrease mortality nor improve oxygenation in inpatient settings, the use of NSAIDs did not increase the rate of death or the need for ventilation in patients with respiratory tract infections. Further studies with a robust methodology and larger sample sizes are recommended.

International journal of antimicrobial agents. 2022;(1):106469
Abstract
OBJECTIVES The aim of this cross-sectional study was to investigate the pattern of antibiotic prescriptions for upper respiratory tract infections (URTIs) in children seen by primary care paediatricians (PCPs). METHODS Data were collected from face-to-face interviews administered to a sample of parents of outpatient children aged 0-14 years in two regions in Southern Italy. To be eligible, children had to be diagnosed with sinusitis, pharyngotonsillitis, otitis media, bronchitis, influenza or a common cold. The presence of an indication of antibiotic therapy was evaluated according to national and international guidelines. RESULTS An antibiotic prescription was indicated in 57 (10.1%) of the sampled patients, of whom 33.3% did not receive an antibiotic prescription; among the 508 patients for whom an antibiotic prescription was not indicated, 27.4% received a prescription. Of all PCP consultations, 72% were appropriate (an antibiotic was prescribed when indicated and not prescribed when not indicated), whilst an antibiotic prescription not indicated by guidelines was given to 24.6% of the participants, and 3.4% of the sample did not receive an antibiotic prescription when indicated. The most frequently prescribed antibiotic was amoxicillin with clavulanic acid. A rapid microbiological examination was performed in two patients. CONCLUSIONS The study findings highlight a high rate of sub-optimal antibiotic therapeutic profile. Over-prescription of antibiotic therapy and the use of broad-spectrum molecules are widespread in children with URTIs. Antibiotic under-prescription, which may deprive paediatric patients of an effective treatment when indicated, also occurs.

Clinical nutrition (Edinburgh, Scotland). 2021;(4):1843-1850
Abstract
BACKGROUND In polymorbid patients with bronchopulmonary infection, malnutrition is an independent risk factor for mortality. There is a lack of interventional data investigating whether providing nutritional support during the hospital stay in patients at risk for malnutrition presenting with lower respiratory tract infection lowers mortality. METHODS For this secondary analysis of a randomized clinical trial (EFFORT), we analyzed data of a subgroup of patients with confirmed lower respiratory tract infection from an initial cohort of 2028 patients. Patients at nutritional risk (Nutritional Risk Screening [NRS] score ≥3 points) were randomized to receive protocol-guided individualized nutritional support to reach protein and energy goals (intervention group) or standard hospital food (control group). The primary endpoint of this analysis was all-cause 30-day mortality. RESULTS We included 378 of 2028 EFFORT patients (mean age 74.4 years, 24% with COPD) into this analysis. Compared to usual care hospital nutrition, individualized nutritional support to reach caloric and protein goals showed a similar beneficial effect of on the risk of mortality in the subgroup of respiratory tract infection patients as compared to the main EFFORT trial (odds ratio 0.47 [95%CI 0.17 to 1.27, p = 0.136] vs 0.65 [95%CI 0.47 to 0.91, p = 0.011]) with no evidence of a subgroup effect (p for interaction 0.859). Effects were also similar among different subgroups based on etiology and type of respiratory tract infection and for other secondary endpoints. CONCLUSION This subgroup analysis from a large nutrition support trial suggests that patients at nutritional risk as assessed by NRS 2002 presenting with bronchopulmonary infection to the hospital likely have a mortality benefit from individualized inhospital nutritional support. The small sample size and limited statistical power calls for larger nutritional studies focusing on this highly vulnerable patient population.

American journal of otolaryngology. 2021;(6):103083
Abstract
PURPOSE Recurrent upper respiratory disorders (RURD) are among the most common problems diagnosed in pediatric otolaryngology practice. Although several preliminary studies have demonstrated beneficial effects of thermal water inhalations for RURD, inhalation of thermal water has not been included among validated management protocols. The effects of sulfurous-arsenical-ferruginous thermal water nasal irrigations have been confirmed also in prospective, randomized studies. The main aim of this explorative, retrospective, observational study has been to compare the clinical outcome in pediatric patients with RURD treated with sulfurous-arsenical-ferruginous thermal water inhalation versus combined inhalation and nasal irrigation. METHODS Two hundred and fifty-three pediatric patients with RURD were considered; 231 underwent thermal water inhalations (inhalation of hot humid air and aerosol) only, while 22 underwent nasal irrigations combined with inhalations. Subjective overall efficacy perception and treatment tolerability were scored as categorical variables (from 0 = no efficacy/worst tolerability to 3 = maximal efficacy/best tolerability). RESULTS Nasal obstruction, sneezing, serous, mucous, and purulent rhinorrhea, cough, and snoring improved respectively in 80.2%, 72.9%, 79.0%, 93.8%, 92.3%, 64.8%, and 60.4% of patients referring these symptoms at presentation, respectively. No statistically significant differences between inhalations alone and combined inhalations and irrigations emerged. The median overall efficacy perception score was 2 while the median treatment tolerability score was 3. CONCLUSIONS This investigation found that sulfurous-arsenical-ferruginous water treatment was a well-tolerated therapeutic option for selected pediatric patients with RURD. These promising preliminary results should be confirmed in prospective, randomized, double-blind settings, also using minimally invasive but objective and quantitative evaluation methods.

Abstract
Currently, the world is under a pandemic of severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), responsible for coronavirus disease 2019 (COVID‑19). This disease is characterized by a respiratory syndrome that can progress to an acute respiratory distress syndrome. To date, limited effective therapies are available for the prevention or treatment of COVID‑19; therefore, it is necessary to propose novel treatment options with immunomodulatory effects. Vitamin D serves functions in bone health and has been recently reported to exert protective effects against respiratory infections. Observational studies have demonstrated an association between vitamin D deficiency and a poor prognosis of COVID‑19; this is alarming as vitamin D deficiency is a global health problem. In Latin America, the prevalence of vitamin D deficiency is unknown, and currently, this region is in the top 10 according to the number of confirmed COVID‑19 cases. Supplementation with vitamin D may be a useful adjunctive treatment for the prevention of COVID‑19 complications. The present review provides an overview of the current knowledge of the potential immunomodulatory effects of vitamin D in the prevention of COVID‑19 and sets out vitamin D recommendations for the Latin American population.

Effect of micronutrient supplements on influenza and other respiratory tract infections among adults: a systematic review and meta-analysis.
Abioye, AI, Bromage, S, Fawzi, W
BMJ global health. 2021;(1)
Abstract
Acute respiratory tract infections (ARIs) are a leading cause of ill-health and death globally. Individual or multiple micronutrients have been shown to modulate immune function and affect the risk and severity of a number of infectious diseases. We systematically reviewed the evidence on the impact of micronutrient supplements to reduce the occurrence of ARIs and shorten the duration of ARI symptoms among adults. Random effects meta-analyses were conducted to estimate the pooled effects of vitamin D, vitamin C, zinc and multiple micronutrient supplementation (MMS) on the occurrence of ARIs and the duration of ARI symptoms. Vitamin D supplementation reduced the risk of ARI (risk ratio (RR)=0.97; 95% CI 0.94 to 1.00; p=0.028) and shortened the duration of symptoms (per cent difference: -6% (95% CI -9% to -2%; p=0.003)). The RR of vitamin D to prevent ARI was farther from the null when diagnosis was based on clinical diagnosis or laboratory testing, compared with self-report and when the loading dose was <60 000 IU. Vitamin C supplementation reduced the risk of ARIs (RR=0.96; 95% CI 0.93 to 0.99; p=0.01) and shortened the duration of symptoms (per cent difference: -9% (95% CI -16% to -2%; p=0.014)). The effect of vitamin C on preventing ARI was stronger among men and in middle-income countries, compared with women and high-income countries, respectively. Zinc supplementation did not reduce the risk of ARIs but shortened the duration of symptoms substantially (per cent difference: -47% (95% CI -73% to -21%; p=0.0004)). Our synthesis of global evidence from randomised controlled trials indicates that micronutrient supplements including zinc, vitamins C and D, and multiple micronutrient supplements may be modestly effective in preventing ARIs and improving their clinical course. Further research is warranted to better understand the effectiveness that individual or multiple micronutrients have on SARS-CoV-2 infection and treatment outcomes.

Abstract
Objetivo. Describir la evidencia disponible sobre la trans-misión por Covid-19 e infecciones respiratorias agudas simi-lares al Covid-19 en espacios públicos abiertos. Material y métodos. La búsqueda incluyó 4 926 artículos en inglés de los años 2000 a 2020. Seis investigadores revisaron el título y el resumen de los artículos de Embase y PubMed; dos inves-tigadores revisaron los de medRxiv. Todos los investigadores revisaron textos completos y otros resolvieron las discre-pancias. Resultados. De los 21 artículos seleccionados, se observó que la presencia de virus en superficies públicas, aguas residuales y áreas exteriores no fue indicativa de trans-misión. No obstante, se observó que el uso de cubrebocas, el lavado de manos, el distanciamiento social, no asistir a eventos masivos y la movilidad individual a espacios públicos podría ayudar a reducir el riesgo de transmisión. Conclusión. Esta información podría coadyuvar a generar recomendaciones en salud pública, sin embargo, es recomendable actualizar esta revisión conforme avance la evidencia científica.

Alcohol Use and the Risk of Communicable Diseases.
Morojele, NK, Shenoi, SV, Shuper, PA, Braithwaite, RS, Rehm, J
Nutrients. 2021;(10)
Abstract
The body of knowledge on alcohol use and communicable diseases has been growing in recent years. Using a narrative review approach, this paper discusses alcohol's role in the acquisition of and treatment outcomes from four different communicable diseases: these include three conditions included in comparative risk assessments to date-Human Immunodeficiency Virus (HIV)/AIDS, tuberculosis (TB), and lower respiratory infections/pneumonia-as well as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) because of its recent and rapid ascension as a global health concern. Alcohol-attributable TB, HIV, and pneumonia combined were responsible for approximately 360,000 deaths and 13 million disability-adjusted life years lost (DALYs) in 2016, with alcohol-attributable TB deaths and DALYs predominating. There is strong evidence that alcohol is associated with increased incidence of and poorer treatment outcomes from HIV, TB, and pneumonia, via both behavioral and biological mechanisms. Preliminary studies suggest that heavy drinkers and those with alcohol use disorders are at increased risk of COVID-19 infection and severe illness. Aside from HIV research, limited research exists that can guide interventions for addressing alcohol-attributable TB and pneumonia or COVID-19. Implementation of effective individual-level interventions and alcohol control policies as a means of reducing the burden of communicable diseases is recommended.

Pediatric pulmonology. 2021;(1):171-178
Abstract
BACKGROUND Children with Down syndrome (DS) are at high risk of respiratory tract infections (RTIs) due to anatomical variations, comorbidities, and immune system immaturity. Evidence on interventions to reduce this risk is incomplete. This study aims to quantify the effect of antibiotics prescribed for RTIs in primary care on the subsequent risk of RTI-related hospitalization for children with DS versus controls. METHODS We conducted a retrospective cohort study of 992 children with DS and 4874 controls managed by UK National Health Service General Practitioners (GPs) and hospitals as identified in CALIBER (Clinical disease research using LInked Bespoke studies and Electronic health Records), 1997-2010. Univariate and multivariate logistic regression were undertaken. RESULTS In children with DS, the prescription of antibiotics following an RTI-related GP consultation did not significantly reduce the risk of RTI-related hospitalization in the subsequent 28 days (risk with antibiotics, 1.8%; without, 2.5%; risk ratio, 0.699; 95% confidence interval, 0.471-1.036). Subgroup analyses showed a risk reduction only in infants with DS, after adjustment for covariates. There was no reduction in risk for controls, overall or across subgroups. CONCLUSIONS In conclusion, while prescription of antibiotics following RTI-related GP consultations were effective for infants with DS in reducing subsequent RTI-related hospitalization, this was not the case for older children with DS. We would encourage further high-quality cohort and randomized controlled trials to interrogate this finding, and to examine the impact of antibiotics on other endpoints, including symptom duration.

The intracellular phase of extracellular respiratory tract bacterial pathogens and its role on pathogen-host interactions during infection.
Lamberti, Y, Surmann, K
Current opinion in infectious diseases. 2021;(3):197-205
Abstract
PURPOSE OF REVIEW An initial intracellular phase of usually extracellular bacterial pathogens displays an important strategy to hide from the host's immune system and antibiotics therapy. It helps the bacteria, including bacterial pathogens of airway diseases, to persist and eventually switch to a typical extracellular infection. Several infectious diseases of the lung are life-threatening and their control is impeded by intracellular persistence of pathogens. Thus, molecular adaptations of the pathogens to this niche but also the host's response and potential targets to interfere are of relevance. Here we discuss examples of historically considered extracellular pathogens of the respiratory airway where the intracellular survival and proliferation is well documented, including infections by Staphylococcus aureus, Bordetella pertussis, Haemophilus influenzae, Pseudomonas aeruginosa, and others. RECENT FINDINGS Current studies focus on bacterial factors contributing to adhesion, iron acquisition, and intracellular survival as well as ways to target them for combatting the bacterial infections. SUMMARY The investigation of common and specific mechanisms of pathogenesis and persistence of these bacteria in the host may contribute to future investigations and identifications of relevant factors and/or bacterial mechanisms to be blocked to treat or improve prevention strategies.
