TL;DR: An approach to the diagnosis of these disorders is suggested and an update on new therapies is provided to help reduce the burden of this complication.
Abstract: Chemotherapy-induced peripheral neuropathy (CIN) is a common toxicity of anticancer treatment and its incidence is growing. It significantly affects quality of life and is a dose-limiting factor that interferes with treatment. Its diagnosis can be established in clinical terms but some complementary tests can help when the diagnosis is difficult. There is still no proven method to prevent it that has become a standard of care in spite of the huge amount of investigation carried out in recent years. There are promising strategies that could help reduce the burden of this complication. This review will suggest an approach to the diagnosis of these disorders and provide an update on new therapies.

TL;DR: In this article, a search for single top quark production in the s channel in proton-proton collisions with the CMS detector at the CERN LHC in decay modes of the top quarks containing a muon or an electron in the final state is presented.
Abstract: A search is presented for single top quark production in the s channel in proton-proton collisions with the CMS detector at the CERN LHC in decay modes of the top quark containing a muon or an electron in the final state. The signal is extracted through a maximum-likelihood fit to the distribution of a multivariate discriminant defined using boosted decision trees to separate the expected signal contribution from background processes. Data collected at centre-of-mass energies of 7 and 8 TeV yield cross sections of 7.1 +/- 8.1 pb and 13.4 +/- 7.3 pb, respectively, and a best fit value of 2.0 +/- 0.9 for the combined ratio of the measured and expected values. The signal significance is 2.5 standard deviations, and the upper limit on the rate relative to the standard model expectation is 4.7 at 95% confidence level.

TL;DR: In this article, a search for new high-mass resonances decaying into electron or muon pairs is presented, where upper limits on the product of a new resonance production cross section and branching fraction to dileptons are calculated in a model-independent manner.
Abstract: A search is presented for new high-mass resonances decaying into electron or muon pairs. The search uses proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 36 fb$^{−1}$. Observations are in agreement with standard model expectations. Upper limits on the product of a new resonance production cross section and branching fraction to dileptons are calculated in a model-independent manner. This permits the interpretation of the limits in models predicting a narrow dielectron or dimuon resonance. A scan of different intrinsic width hypotheses is performed. Limits are set on the masses of various hypothetical particles. For the $ {Z}_{\mathrm{SSM}}^{\prime}\left({Z}_{{}^{\psi}}^{\prime}\right) $ particle, which arises in the sequential standard model (superstring-inspired model), a lower mass limit of 4.50 (3.90) TeV is set at 95% confidence level. The lightest Kaluza-Klein graviton arising in the Randall-Sundrum model of extra dimensions, with coupling parameters k/M$_{Pl}$ of 0.01, 0.05, and 0.10, is excluded at 95% confidence level below 2.10, 3.65, and 4.25 TeV, respectively. In a simplified model of dark matter production via a vector or axial vector mediator, limits at 95% confidence level are obtained on the masses of the dark matter particle and its mediator.
