The American Thoracic Society, Centers for Disease Control and Prevention, and Infectious Diseases Society of America jointly sponsored the development of this guideline for the treatment of drug-susceptible tuberculosis, which is also endorsed by the European Respiratory Society and the US National Tuberculosis Controllers Association. Representatives from the American Academy of Pediatrics, the Canadian Thoracic Society, the International Union Against Tuberculosis and Lung Disease, and the World Health Organization also participated in the development of the guideline. This guideline provides recommendations on the clinical and public health management of tuberculosis in children and adults in settings in which mycobacterial cultures, molecular and phenotypic drug susceptibility tests, and radiographic studies, among other diagnostic tools, are available on a routine basis. For all recommendations, literature reviews were performed, followed by discussion by an expert committee according to the Grading of Recommendations, Assessment, Development and Evaluation methodology. Given the public health implications of prompt diagnosis and effective management of tuberculosis, empiric multidrug treatment is initiated in almost all situations in which active tuberculosis is suspected. Additional characteristics such as presence of comorbidities, severity of disease, and response to treatment influence management decisions. Specific recommendations on the use of case management strategies (including directly observed therapy), regimen and dosing selection in adults and children (daily vs intermittent), treatment of tuberculosis in the presence of HIV infection (duration of tuberculosis treatment and timing of initiation of antiretroviral therapy), as well as treatment of extrapulmonary disease (central nervous system, pericardial among other sites) are provided. The development of more potent and better-tolerated drug regimens, optimization of drug exposure for the component drugs, optimal management of tuberculosis in special populations, identification of accurate biomarkers of treatment effect, and the assessment of new strategies for implementing regimens in the field remain key priority areas for research.

Abstract. OBJECTIVE:To explore the effects of Dance Therapy (DT) and Traditional Rehabilitation (TR) on both motor and cognitive domains in Parkinson's Disease patients (PD) with postural instability. METHODS: Sixteen PD patients with recent history of falls were divided in two groups (Dance Therapy, DT and Traditional Rehabilitation, TR); nine patients received 1-hour DT classes twice per week, completing 20 lessons within 10 weeks; seven patients received a similar cycle of 20 group sessions of 60 minutes TR. Motor (Berg Balance Scale -BBS, Gait Dynamic Index -GDI, Timed Up and Go Test -TUG, 4 Square-Step Test -4SST, 6-Minute Walking Test -6MWT) and cognitive measures (Frontal Assessment Battery -FAB, Trail Making Test A & B -TMT A&B, Stroop Test) were tested at baseline, after the treatment completion and after 8-week follow-up. RESULTS: In the DT group, but not in the TR group, motor and cognitive outcomes significantly improved after treatment and retained after follow-up. Significant changes were found for 6MWT (p = 0.028), TUG (p = 0.007), TMT-A (p = 0.014) and TMT-B (p = 0.036). CONCLUSIONS: DT is an unconventional physical therapy for PD patients which effectively impacts on motor (endurance and risk of falls) and non-motor functions (executive functions).

IntroductionReverse transcription-polymerase chain reaction (RT-PCR) to detect SARS-CoV-2 is time-consuming and sometimes not feasible in developing nations. Rapid antigen test (RAT) could decrease the load of diagnosis. However, the efficacy of RAT is yet to be investigated comprehensively. Thus, the current systematic review and meta-analysis were conducted to evaluate the diagnostic accuracy of RAT against RT-PCR methods as the reference standard.MethodsWe searched the MEDLINE/Pubmed and Embase databases for the relevant records. The QUADAS-2 tool was used to assess the quality of the studies. Diagnostic accuracy measures [i.e., sensitivity, specificity, diagnostic odds ratio (DOR), positive likelihood ratios (PLR), negative likelihood ratios (NLR), and the area under the curve (AUC)] were pooled with a random-effects model. All statistical analyses were performed with Meta-DiSc (Version 1.4, Cochrane Colloquium, Barcelona, Spain).ResultsAfter reviewing retrieved records, we identified 60 studies that met the inclusion criteria. The pooled sensitivity and specificity of the rapid antigen tests against the reference test (the real-time PCR) were 69% (95% CI: 68–70) and 99% (95% CI: 99–99). The PLR, NLR, DOR and the AUC estimates were found to be 72 (95% CI: 44–119), 0.30 (95% CI: 0.26–0.36), 316 (95% CI: 167–590) and 97%, respectively.ConclusionThe present study indicated that using RAT kits is primarily recommended for the early detection of patients suspected of having COVID-19, particularly in countries with limited resources and laboratory equipment. However, the negative RAT samples may need to be confirmed using molecular tests, mainly when the symptoms of COVID-19 are present.

Background The sexual dimorphism represents one of the triggers of the metabolic disparities between the organisms, advising about wild implications in research or diagnostics contexts. Despite the mounting recognition of the importance of sex consideration in the biomedical fields, the identification of male- and female-specific metabolic signatures has not been achieved. Main body This review pointed the focus on the metabolic differences related to the sex, evidenced by metabolomics studies performed on healthy populations, with the leading aim of understanding how the sex influences the baseline metabolome. The main shared signatures and the apparent dissimilarities between males and females were extracted and highlighted from the metabolome of the most commonly analyzed biological fluids, such as serum, plasma, and urine. Furthermore, the influence of age and the significant interactions between sex and age have been taken into account. Conclusions The recognition of sex patterns in human metabolomics has been defined in diverse biofluids. The detection of sex- and age-related differences in the metabolome of healthy individuals are helpful for translational applications from the bench to the bedside to set targeted diagnostic and prevention approaches in the context of personalized medicine. Graphical Abstract

<b><i>Background:</i></b> The role of endoscopic ultrasound with bronchoscope fine-needle aspiration (EUS-B-FNA) in the diagnosis of suspected malignant pulmonary lesions adjacent to the esophagus has been poorly investigated. The aim of the present study was to assess the accuracy of EUS-B-FNA for the diagnosis and molecular profiling of paraesophageal pulmonary lesions, as well as its predictors of success. <b><i>Materials and Methods:</i></b> Patients who underwent EUS-B-FNA for the diagnosis of paraesophageal lesions were consecutively enrolled in four Italian centers. Demographic, clinical, procedural, pathological, and molecular characteristics of the malignant samples were collected. The primary outcome was the diagnostic accuracy for pulmonary malignancies. Secondary outcomes were diagnostic yield and predictors of success for diagnosis and molecular profiling. <b><i>Results:</i></b> 107 adult patients (60 [56.1%] males; median (interquartile range) age: 69 [60–70] years) were enrolled. The diagnostic accuracy of EUS-B-FNA was 95.3% in the overall cohort and 95.2% in the 99 patients with a final diagnosis of malignancy. Neither clinical nor procedural variables significantly affected the diagnostic accuracy, whereas rapid on-site evaluation (ROSE), performed by pathologists or trained pulmonologists, was a strong predictor for a complete molecular profiling (OR [95% CI]: 12.9 [1.2–137.4]; <i>p</i> value: 0.03). <b><i>Conclusion:</i></b> EUS-B-FNA is a safe and accurate method for the diagnosis of paraesophageal pulmonary lesions. The presence of ROSE is relevant for a complete molecular profiling in this selected cohort of patients with advanced lung cancer.

Background: Although previous studies showed an increasing prevalence of infections due to multi-drug resistant (MDR) bacteria in the community, specific data on sepsis are lacking. We aimed to assess prevalence, risk factors and outcomes of patients with sepsis due to MDR bacteria. Methods: An observational, retrospective study was conducted on consecutive adult patients coming from the community and admitted to the Policlinico Hospital, Milan, Italy, with a diagnosis of sepsis between January 2011 and December 2015. Primary study outcome was in-hospital mortality. Results: Among 518 patients, at least one MDR bacteria was isolated in 88 (17%). ESBL+ Enterobacteriaceae were the most prevalent MDR bacteria (9.7%) followed by MRSA (3.9%). Independent risk factors for sepsis due to MDR bacteria were septic shock (OR: 2.2; p = 0.002) and hospitalization in the previous 90 days (OR: 2.3; p = 0.003). Independent risk factors for sepsis due to ESBL+ bacteria were hospitalization in the previous 90 days (OR: 2.1; p = 0.02) and stroke (OR: 2.1; p = 0.04). A significantly higher mortality was detected among patients with vs. without MDR bacteria (40.2% vs. 23.1% respectively, p = 0.001). Independent risk factors for mortality among patients with sepsis were coagulation dysfunction (OR: 3.2; p = 0.03), septic shock (OR: 3.2; p = 0.003), and isolation of a MDR bacteria (OR: 4.6; p < 0.001). Conclusion: In light of the prevalence and impact of MDR bacteria causing sepsis in patients coming from the community, physicians should consider ESBL coverage when starting an empiric antibiotic therapy in patients with specific risk factors, especially in the presence of septic shock.

<b><i>Background:</i></b> Idiopathic pulmonary fibrosis (IPF) primarily affects old patients. Old age is a predictor of mortality. Nintedanib, the only antifibrotic drug approved in Italy for patients aged &#x3e;80 years, can slow the progression of IPF by reducing the rate of decline in forced vital capacity (FVC) and the risk of exacerbations. <b><i>Objectives:</i></b> The primary aim of the study was to compare the decline of FVC after 12 months of nintedanib in patients aged &#x3e;80 years versus younger patients. Differences related to other functional data, safety, tolerability, hospitalizations, exacerbations, and mortality were evaluated. <b><i>Methods:</i></b> An observational, retrospective, multicenter study was carried out in Italy. <b><i>Results:</i></b> 159 (122 [76.7%] males) patients were recruited: 106 (66.7%) aged ≤80 years and 53 (33.3%) aged &#x3e;80 years. FVC decline after 12 months of therapy was not significantly different (−45 mL [−170; 75] vs. −20 mL [−138; 110] mL; <i>p</i>: 0.51). No differences were found for other functional data. Diarrhea was the most frequent adverse event (AE). Rate and type of any AEs, permanent/temporary dose reduction, or drug discontinuation were not significantly different between patients aged ≤80 vs. &#x3e;80 years. Furthermore, acute exacerbations, hospitalization, and mortality were not significantly different. <b><i>Conclusions:</i></b> Nintedanib is effective and safe in patients with IPF aged &#x3e;80 years, and no significant differences were found when clinical outcomes were compared with those of younger patients. Thus, older age should not be a barrier for the early prescription of antifibrotic treatment in IPF patients.
