Patients were undernourished and BMI percentiles did not differ between groups (30.7% vs 43.4%, p=0.32 at baseline, 37.9% vs. 37.6%, p=0.98 at 5 years). There was no difference in the pulmonary exacerbation rate (3.0/year vs 2.5/year, p=0.34). Genotyping showed diverse genetic strains between patients.
Inquilinus can present in childhood and is often associated with chronic infection in CF. Lung function and nutrition status at time of detection, lung function decline, and pulmonary exacerbation rates in Inquilinus cases were similar to those with chronic P. aeruginosa, a well-established CF pathogen.

The cilium originates from the mother centriole through a complex set of cellular events requiring hundreds of distinct components. Aberrant ciliogenesis or ciliary transport leads to a broad spectrum of clinical entities with overlapping yet highly variable phenotypes, collectively called ciliopathies, which include sensory defects and syndromic disorders with multi-organ pathologies. For efficient light detection, photoreceptors in the retina elaborate a modified cilium known as the outer segment, which is packed with membranous discs enriched for components of the phototransduction machinery. Retinopathy phenotype involves dysfunction and/or degeneration of the light sensing photoreceptors and is highly penetrant in ciliopathies. This review will discuss primary cilia biogenesis and ciliopathies, with a focus on the retina, and the role of CP110-CEP290-CC2D2A network. We will also explore how recent technologies can advance our understanding of cilia biology and discuss new paradigms for developing potential therapies of retinal ciliopathies.During mitosis microtubules self-organize to form a bipolar mitotic spindle structure, which positions the sister chromatids on the spindle mid-plane and separates them afterwards. Previous studies have identified many spindle associated proteins. Yet, we do not fully understand how these nanoscopic proteins lead to force generation through interactions of individual microtubules, motor proteins and chromosomes, and how a large number of these local interactions ultimately determine the structure and mechanics of the spindle in micron scale. Here we review the current understanding and open questions related to the structure and mechanics of the mitotic spindle. We then discuss how a combination of electron microscopy and computational modeling can be used to tackle some of these open questions.
Continuing tyrosine kinase inhibitor (TKI) therapy may be beneficial when patients with non-small-cell lung cancer and EGFR mutations experience gradual disease progression after initial EGFR-TKI treatment. We aimed to compare the efficacy of simultaneous EGFR-TKI and chemotherapy with that of sequential treatment after patients’ disease gradually progressed after first-line EGFR-TKI treatment.
Patients with gradual progression who were EGFR-T790M mutation negative were randomly divided into two groups. In the concurrent group, patients were treated with pemetrexed plus cisplatin along with the same EGFR-TKI. In the sequential group, patients continued with EGFR-TKI until the disease progressed again, according to RECIST, then switched to chemotherapy. We evaluated the patients’ progression-free survival (PFS) and overall survival times.
Ninety-nine patients were enrolled 49 in the concurrent group and 50 in the sequential group. The median PFS (mPFS) was 7.7 months (95% confidence interval [CI], 3.6-11.7) in the concurrent group and 5.7 months (95% CI, 3.5-7.9) in the sequential group (hazard ratio= 0.66; 95% CI, 0.44-1.00; P= .026), respectively. For the sequential group, the mPFS1 and mPFS2 were 1.8 months (95% CI, 1.4-2.3) and 3.8 months (95% CI, 3.1-4.5), respectively. The median overall survival of the concurrent group was longer than that of the sequential group (20.0 vs. 14.7 months; hazard ratio=0.52; 95% CI, 0.32-0.85; P= .038).
For patients with advanced non-small-cell lung cancer and gradual progression who are EGFR-T790M mutation negative after initial EGFR-TKI therapy, EGFR-TKI combined with chemotherapy confers longer PFS and overall survival than sequential EGFR-TKI and chemotherapy does.

Recognizing entrapment neuropathy early can help avoid progressive neurological deficits, as well as facilitate appropriate treatment measures, which can effectively minimize a patient’s symptoms. Entrapment neuropathies may be distinguished from other musculoskeletal causes of lower extremity pain by identifying characteristic patterns of weakness and/or sensory loss, so a focused bedside neurological examination is key for diagnosis. In this chapter, we review the most common entrapment neuropathies that occur in the lower extremities, review the relevant neuroanatomy, outline a diagnostic approach to distinguish them from other mimics, and highlight appropriate management options.
The serologic response of individuals with mild forms of SARS-CoV-2 infection is poorly characterized.
Hospital staff who had recovered from mild forms of PCR-confirmed SARS-CoV-2 infection were tested for anti-SARS-CoV-2 antibodies using two assays a rapid immunodiagnostic test (99.4% specificity) and the S-Flow assay (~99% specificity). The neutralizing activity of the sera was tested with a pseudovirus-based assay.
Of 162 hospital staff who participated in the investigation, 160 reported SARS-CoV-2 infection that had not required hospital admission and were included in these analyses. The median time from symptom onset to blood sample collection was 24 days (IQR 21-28, range 13-39). The rapid immunodiagnostic test detected antibodies in 153 (95.6%) of the samples and the S-Flow assay in 159 (99.4%), failing to detect antibodies in one sample collected 18 days after symptom onset (the rapid test did not detect antibodies in that patient). Neutralizing antibodies (NAbs) were detected in 79%, 92% and 98% of samples collected 13-20, 21-27 and 28-41 days after symptom onset, respectively (P=0.
