Infections with extensively drug-resistant Acinetobacter baumannii (XDRAB) have limited therapeutic options. We report successful salvage treatment of XDRAB and Pseudomonas aeruginosa-infected retained spinal hardware with cefiderocol, despite the development of reversible acute interstitial nephritis after 32 days of treatment.

This study was performed to identify and characterize circulating Plasmodium species in three provinces of Mindanao approaching malaria elimination.

Rapid diagnostic tests (RDT), microscopic examination, and PCR were used to detect malaria parasites. PCR-positive isolates were genotyped for polymorphisms in loci of interest.

A total of 2639 participants were surveyed in Mindanao between 2010 and 2013. Malaria prevalence by PCR was 3.8% (95% confidence interval (CI) 2.7-5.2%) in Sarangani, 10% (95% CI 7.7-12.7%) in South Cotabato, and 4.2% (95% CI 3.2-5.6%) in Tawi-Tawi. P. falciparum and P. vivax were identified in all three provinces, and there was one case of P. selleck inhibitor malariae in South Cotabato. RDT was inferior to PCR for detecting asymptomatic P. falciparum and P. vivax. In Tawi-Tawi, microscopy failed to identify 46 PCR-positive malaria infections. The presence of pfcrt haplotypes CVMNK, CVIET, and SMNT (codons 72-76), pfmdr1 haplotype NFSND (codons 86, 184, 1034, 1042, 1246), and pvmdr1 haplotype NFL (codons 91, 976, 1076) was confirmed in Mindanao.

Asymptomatic Plasmodium infections persisted in local communities between 2010 and 2013. PCR successfully identified subpatent malaria infections, and can better characterize malaria epidemiology in communities seeking malaria control and elimination at the local level.

Some countries have already achieved high vaccination rates, offering a glimpse into the so-called "post-vaccination" world. We describe here a striking comparison between the similar-sized and neighboring countries of Bahrain and Qatar. While both countries have achieved impressive vaccination rates, cases increased to unprecedented levels in one country while decreasing steadily in the other. Although this could be attributed to a number of factors, we argue here that the heavy reliance on alum-adjuvanted inactivated virus vaccines may have contributed to these discrepant outcomes. We then expand the analysis to compare the outcomes of the top 10 vaccinated countries based on their reliance on inactivated virus vaccines. The results remarkably align with the initial findings seen in Bahrain and Qatar. Countries that did not use inactivated virus vaccines achieved steady declines in daily COVID-19 deaths, while other countries did not. This work highlights the urgent need to further study the effectiveness of alum-adjuvanted inactivated virus vaccines for COVID-19 before expanding their use.

Randomized trials are generally performed from a frequentist perspective, which can conflate absence of evidence with evidence of absence. The RECOVERY trial evaluated convalescent plasma for patients hospitalized with coronavirus disease 2019 (COVID-19) and concluded that there was no evidence of an effect. Re-analysis from a Bayesian perspective is warranted.

Outcome data were extracted from the RECOVERY trial by serostatus and time of presentation. A Bayesian re-analysis with a wide variety of priors (vague, optimistic, sceptical, and pessimistic) was performed, calculating the posterior probability for any benefit, an absolute risk difference of 0.5% (small benefit, number needed to treat 200), and an absolute risk difference of one percentage point (modest benefit, number needed to treat 100).

Across all patients, when analysed with a vague prior, the likelihood of any benefit or a modest benefit with convalescent plasma was estimated to be 64% and 18%, respectively. The estimated chance of any benmortality reduction in the 38% who are seronegative at the time of presentation. This is in contrast to the results in people who already have antibodies when they present. This biologically plausible finding bears witness to the advantage of Bayesian analyses over misuse of hypothesis tests to inform decisions.Cystic fibrosis (CF) is characterized by small airway disease; but central airways may also be affected. We hypothesized that airway resistance estimated from computational fluid dynamic (CFD) methodology in infants with CF was higher than controls and that early airway inflammation in infants with CF is associated with airway resistance. Central airway models with a median of 51 bronchial outlets per model (interquartile range 46,56) were created from chest computed tomography scans of 18 infants with CF and 7 controls. Steady state airflow into the trachea was simulated to estimate central airway resistance in each model. Airway resistance was increased in the full airway models of infants with CF versus controls and in models trimmed to 33 bronchi. Airway resistance was associated with markers of inflammation in bronchoalveolar lavage fluid obtained approximately 8 months earlier but not with markers obtained at the same time. In conclusion, airway resistance estimated by CFD modeling is increased in infants with CF compared to controls and may be related to early airway inflammation.Massive pulmonary embolism (MPE) is associated with a 20-50% mortality rate with guideline directed therapy. MPE treatment with surgical embolectomy (SE) or venoarterial extracorporeal membrane oxygenation (VA-ECMO) have shown promising results. In the context of a surgical management strategy for MPE, a comparison of outcomes associated with VA-ECMO or SE was performed. A retrospective review of a single institution cardiac surgery database was performed, identifying MPE treated with SE or VA-ECMO between 2005-2020. Primary outcome was in-hospital survival. 59 MPE [27 (46.8%) VA-ECMO vs 32 (54.2%) SE] were identified. All presented with elevated cardiac biomarkers, tachycardia (mean heart rate 113 ± 20 beats/minute), hypotension (mean systolic blood pressure 85 ± 22 mm Hg) and vasopressors requirement, without significant differences between cohorts. Preoperative CPR was performed in 37.3% (22/59), without a significant difference between cohorts. More VA-ECMO presented with questionable neurologic status (GCS ≤ 4) [9/27 (33.3%) vs 2/32 (6.2%), P = 0.008] and more VA-ECMO failed thrombolysis [8/27 (29.6) vs 2/32 (6.3), P = 0.014]. All presented with severe RV dysfunction, by discharge all had normalization of echocardiographic RV function. Overall mortality was 10.2%, with a trend toward higher mortality among VA-ECMO [14.9% (4/27) vs 6.3% (2/32) P = 0.14]. CPR was independently associated with death (OR 10.8, P = 0.02) whereas treatment modality was not (OR 0.24). In an extremely unstable MPE population VA-ECMO and SE were safely performed with low mortality while achieving RV recovery. Adverse outcomes were more closely associated with preoperative CPR than with treatment modality.To evaluate the diagnostic accuracy of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) and Endoscopic Ultrasound-guided Fine Needle Aspiration (EUS-FNA) in the diagnosis of lymphoma. A retrospective analysis of patients with suspected mediastinal lymphoproliferative disorders who underwent EBUS-TBNA, EUS-FNA or combined procedures from 2009 to 2019 was conducted using a prospectively maintained interventional thoracic endoscopy database. Demographic data, imaging, needle size, surgical biopsy, complications rate and pathology reports were reviewed. Over a 10-year period, a total of 444 patients were investigated with endosonography as the first diagnostic procedure for mediastinal adenopathy suspicious for lymphoma. Lymphoma was diagnosed in 77 patients (17.3%). In total, 68 patients (88.3%) were diagnosed using endosonographic mediastinal tissue sampling. Four patients had both lymphoproliferative disorders and lung cancer. Nine patients (11.7%) required a surgical biopsy to confirm the lymphoma diagnosis (6 non-diagnostic; 3 inadequate samples from endosonographic biopsies). In patients with adequate biopsies via endosonography, the sensitivity for the diagnosis of lymphoma, was 91.9% (n = 68/74). The histopathologic subtype of lymphoma was determined by endosonographic biopsies in 61 patients (89.7%) with an increased sensitivity (92.6%) for low grade Non-Hodgkin lymphoma (NHL). No acute complication related to endosonography was observed. Endosonographic biopsy (EBUS and/or EUS) of mediastinal adenopathy in patients with suspected lymphoma is a highly sensitive and safe diagnostic test. Endosonography should be the first test in the diagnosis of suspicious mediastinal lymphoma and should be followed by surgical biopsy in cases of insufficient sampling or indefinite diagnosis.

Yolk sac tumor (YST) is a malignant entity that often occurs in girls less than 3 years of age and is the most frequent type of primary extragonadal germ cell tumor.

We describe the case of an 11-month-old girl who was referred to our center for vaginal bleeding with evidence of a uterine mass on ultrasonography. Preoperative investigations confirmed YST of the uterine cervix without metastasis. After 4 cycles of systemic chemotherapy, the patient was treated with laparoscopic trachelectomy (fertility-sparing surgery) without perioperative complications.

After 12 months of follow-up, no residual mass was seen. The laparoscopic technique for trachelectomy for uterine cervix YST seems to be feasible and safe in children under 1 year of age.

Quantification of CPV-2 specific antibodies before vaccination can reveal the presence of interfering maternal-derived immunity and facilitate timing of effective immunisation. Inhibition of haemagglutination (HI) is commonly used to measure CPV-2-specific antibody levels in serum. However, the presence of nonspecific agglutinins in canine serum and artefactual precipitation of red blood cells (RBC) are both limitations of the assay. In this study, we compared the standard HI protocol with a refined HI protocol, in which canine serum was pre-incubated with porcine RBC for 12 h to remove nonspecific agglutinins and a lower concentration (0.1% vs. 0.8%) of porcine RBC suspensions was used to limit artefactual precipitation of RBC. A panel of canine sera, collected from 80 dogs of different ages and with different neutralising antibody titres, was analysed. Nonspecific agglutinins were identified in most (97%) serum samples from puppies less then 4 months of age and in only 7% dogs 6 months old. Pre-treatment of serum samples was effective in removing nonspecific agglutinins from all samples and artefactual precipitation of RBCs was not noted when 0.1% RBC suspensions were used. Refinement of the HI protocol has increased the accuracy of interpretation and reduced the interference of nonspecific agglutinins, primarily seen in puppies. This reduces the likelihood of incorrect assessment of passive or active immunity in puppies when deciding whether to administer or defer vaccination, which could potentially leave them susceptible to CPV-2 infection.
